The heartache of bereavement can be fatal in heart failure
that points to the need for greater integration of psychosocial risk factors in the treatment of HF.
The adjusted relative risk of dying was nearly 30% higher among bereaved patients with HF (1.29; 95% confidence interval, 1.27-1.30) and slightly higher for those grieving the loss of more than one family member (RR, 1.35).
The highest risk was in the first week after the loss (RR, 1.78) but persisted after 5 years of follow-up (RR, 1.30).
“Heart failure is a very difficult condition and has a very poor prognosis comparable to many, many cancers,” senior author Krisztina László, PhD, Karolinska Institutet, Stockholm, said in an interview. “So it’s important for us to be aware of these increased risks and to understand them better.”
The early risk for death could be related to stress-induced cardiomyopathy, or Takotsubo syndrome, as well as activation of the hypothalamic-pituitary-adrenal axis, the renin-angiotensin-aldosterone system, and sympathetic nervous system, she explained. Higher long-term risks may reflect chronic stress, leading to poorly managed disease and an unhealthy lifestyle.
“If we understand better the underlying mechanisms maybe we can give more specific advice,” Dr. László said. “At this stage, I think having an awareness of the risk and trying to follow patients or at least not let them fall out of usual care, asking questions, trying to understand what their needs are, maybe that is what we can do well.”
A recent position paper by the European Association of Preventive Cardiology pointed out that psychosocial risk factors, like depression and social isolation, can exacerbate heart failure and calls for better integration of psychosocial factors in the treatment of patients with chronic HF.
“We don’t do a very good job of it, but I think they are very important,” observed Stuart D. Russell, MD, a professor of medicine who specializes in advanced HF at Duke University, Durham, N.C., and was not involved in the study.
“When we hear about a spouse dying, we might call and give condolences, but it’s probably a group of patients that for the next 6 months or so we need to watch more closely and see if there are things we can impact both medically as well as socially to perhaps prevent some of this increase in mortality,” he told this news organization.
Although several studies have linked bereavement with adverse health outcomes, this is just one of two studies to look specifically at its role in HF prognosis, Dr. László noted. A 2013 study of 66,000 male veterans reported that widowers had nearly a 38% higher all-cause mortality risk than did married veterans.
The present study extends those findings to 490,527 patients in the Swedish Heart Failure Registry between 2000 and 2018 and/or in the Swedish Patient Register with a primary diagnosis of HF between 1987 and 2018. During a mean follow-up of 3.7 years, 12% of participants had a family member die, and 383,674 participants died.
Results showed the HF mortality risk increased 10% after the death of a child, 20% with the death of a spouse/partner, 13% with a sibling’s death, and 5% with the death of a grandchild.
No increased risk was seen after the death of a parent, which is likely owed to a median patient age of about 75 years and “is in line with our expectations of the life cycle,” Dr. László said.
An association between bereavement and mortality risk was observed in cases of loss caused by cardiovascular disease (RR, 1.34) and other natural causes (RR, 1.27) but also in cases of unnatural deaths, such as suicide (RR, 1.13).
The overall findings were similar regardless of left ventricular ejection fraction and New York Heart Association functional class and were not affected by sex or country of birth.
Dr. Russell agreed that the death of a parent would be expected among these older patients with HF but said that “if the mechanism of this truly is kind of this increased stress hormones and Takotsubo-type mechanism, you’d think it would be worse if it was your kid that died. That shocked me a bit.”
The strong association between mortality and the loss of a spouse or partner was not surprising, given that they’re an important source of mutual social support, he added.
“If it’s a 75-year-old whose spouse dies, we need to make sure that we have the children’s phone number or other people that we can reach out to and say: ‘Can you check on them?’ ” he said. “And we need to make sure that somebody else is coming in with them because I would guess that probably at least half of what patients hear in a clinic visit goes in one ear and out the other and it’s going to make that much better. So we need to find who that new support person is for the patient.”
Asked whether there are efforts underway to incorporate psychosocial factors into current U.S. guidelines, Dr. Russell replied, “certainly within heart failure, I don’t think we’re really discussing it and, that may be the best part of this paper. It really makes us think about a different way of approaching these older patients.”
Dr. László said that future studies are needed to investigate whether less severe sources of stress may also contribute to poor HF prognosis.
“In our population, 12% of patients were affected, which is quite high, but there are patients with heart failure who experience on a daily basis other sources of stress, which are less severe but chronic and affect large numbers,” she said. “This may also have important public health implications and will be an important next step.”
The authors noted that they were unable to eliminate residual confounding by genetic factors or unmeasured socioeconomic-, lifestyle-, or health-related factors shared by family members. Other limitations are limited power to detect a modest effect in some of the subanalyses and that the findings may be generalizable only to countries with social and cultural contexts and health-related factors similar to those of Sweden.
The study was supported by grants from the Swedish Council for Working Life and Social Research, the Karolinska Institutet’s Research Foundation, and the China Scholarship Council. Dr. László is also supported by a grant from the Heart and Lung Foundation. All other authors and Dr. Russell reported no relevant financial relationships.

FROM JACC: HEART FAILURE
Pulse oximeters lead to less oxygen supplementation for people of color
The new research suggests that skin color–related differences in pulse oximeter readings are in fact impacting clinical decision-making, lead author Eric R. Gottlieb, MD, of Brigham and Women’s Hospital and Massachusetts Institute of Technology, both in Boston, and colleagues wrote. This suggests that technology needs to updated to improve health equity, they continued, in their paper published in JAMA Internal Medicine.
“It has been known for decades that these readings are affected by various surface pigmentations, including nail polish and skin melanin, which may affect light absorption and scattering,” the investigators wrote. “This increases the risk of hidden hypoxemia [among patients with darker skin], in which patients have falsely elevated SpO2 readings, usually defined as 92% or greater, with a blood hemoglobin oxygen saturation less than 88%.”
Although published reports on this phenomenon date back to the 1980s, clinical significance has been largely discounted, they said, citing a 2008 paper on the topic, which stated that “oximetry need not have exact accuracy” to determine if a patient needs oxygen supplementation.
‘We’re not providing equal care’
Questioning the validity of this statement, Dr. Gottlieb and colleagues conducted a retrospective cohort study involving 3,069 patients admitted to intensive care at the Beth Israel Deaconess Medical Center in Boston between 2008 and 2019, thereby excluding patients treated during the COVID-19 pandemic. The population consisted of four races/ethnicities: White (87%), Black (7%), Hispanic (4%), and Asian (3%).
Aligning with previous studies, multivariable linear regression analyses showed that Asian, Black, and Hispanic patients had significantly higher SpO2 readings than White patients in relation to hemoglobin oxygen saturation values, suggesting falsely elevated readings.
Further modeling showed that these same patient groups also received lower oxygen delivery rates, which were not explained directly by race/ethnicity, but instead were mediated by the discrepancy between SpO2 and hemoglobin oxygen saturation values. In other words, physicians were responding consistently to pulse oximetry readings, rather than exhibiting a direct racial/ethnic bias in their clinical decision-making.
“We’re not providing equal care,” Dr. Gottlieb said in an interview. “It’s not that the patients are sicker, or have other socioeconomic explanations for why this happens to them. It’s us. It’s our technology. And that’s something that really has to be fixed.”
The investigators offered a cautionary view of corrective algorithms, as these “have exacerbated disparities and are subject to ethical concerns;” for example, with glomerular filtration rate estimations in Black patients.
Dr. Gottlieb also cautioned against action by individual physicians, who may now be inclined to change how they interpret pulse oximeter readings based on a patient’s race or ethnicity.
“I don’t think that we can expect physicians, every time they see a patient, to be second guessing whether the number basically reflects the truth,” he said.
Instead, Dr. Gottlieb suggested that the burden of change rests upon the shoulders of institutions, including hospitals and device manufacturers, both of which “really need to take the responsibility” for making sure that pulse oximeters are “equitable and have similar performance across races.”
While Dr. Gottlieb said that skin color likely plays the greatest role in measurement discrepancies, he encouraged stakeholders “to think broadly about this, and not just assume that it’s entirely skin color,” noting a small amount of evidence indicating that blood chemistry may also play a role. Still, he predicted that colorimetry – the direct measurement of skin color – will probably be incorporated into pulse oximeters of the future.
Black patients 3X more likely to have hidden hypoxia than White patients
Michael Sjoding, MD, of the University of Michigan, Ann Arbor, was one of the first to raise awareness of skin color–related issues with pulse oximeters during the throes of the COVID-19 pandemic. His study, which involved more than 10,000 patients, showed that Black patients were threefold more likely to have hidden hypoxia than White patients.
The present study shows that such discrepancies are indeed clinically significant, Dr. Sjoding said in an interview. And these data are needed, he added, to bring about change.
“What is being asked is potentially a big deal,” Dr. Sjoding said. “Pulse oximeters are everywhere, and it would be a big undertaking to redesign pulse oximeters and purchase new pulse oximeters. You need a compelling body of evidence to do that. I think it’s there now, clearly. So I’m hopeful that we’re going to finally move forward, towards having devices that we are confident work accurately in everyone.”
Why it has taken so long to gather this evidence, however, is a thornier topic, considering race-related discrepancies in pulse oximeter readings were first documented more than 3 decades ago.
“We sort of rediscovered something that had been known and had been described in the past,” Dr. Sjoding said. He explained how he and many of his colleagues had completed pulmonary fellowships, yet none of them knew of these potential issues with pulse oximeters until they began to observe differences in their own patients during the pandemic.
“I’ll give previous generations of researchers the benefit of the doubt,” Dr. Sjoding said, pointing out that techniques in data gathering and analysis have advanced considerably over the years. “The types of studies that were done before were very different than what we did.”
Yet Dr. Sjoding entertained the possibility that other factors may have been at play.
“I think definitely there’s a social commentary on prioritization of research,” he said.
The study was supported by grants from the National Institutes of Health. The investigators and Dr. Sjoding reported no conflicts of interest.

Physicians urged to write indications on drug scripts as methotrexate users face new barriers with SCOTUS decision
.
The Court’s 5-4 decision in Dobbs v. Jackson Women’s Health Organization, which halted abortion procedures across the country, also appears to be affecting certain drug regimens. Reports have emerged that pharmacies are denying access to methotrexate (MTX), a drug often used in patients with arthritis or cancer, as well as psoriasis and other skin diseases. In very high doses, MTX it is used to terminate an ectopic pregnancy after miscarriage. The drug can also lead to birth defects.
“It’s happening all over,” Donald Miller, PharmD, professor of pharmacy practice at North Dakota State University, Fargo, said in an interview. “Pharmacists are reluctant to dispense it, and rheumatologists are reluctant to prescribe it because they’re afraid of going to jail.”
Becky Schwartz, a patient who takes MTX for lupus, recently tweeted that her physician’s office stopped prescribing the drug because it is considered an abortifacient. “I had care that made my disabled life easier, and [the Supreme Court] took that from me,” Ms. Schwartz wrote.
Prior to the Supreme Court’s ruling, physicians were concerned about the impact an overturning of the 1973 law would have on patient access to MTX and other prescription medications with abortifacient properties. Doctors in general are becoming afraid of prescribing anything that’s a teratogen, said Dr. Miller.
MTX is used far more often for autoimmune disease than as an abortifacient, said rheumatologist Kristen Young, MD, clinical assistant professor at the University of Arizona College of Medicine, Phoenix. It’s a slippery slope if states reacting to the Supreme Court ruling start regulating oral abortifacients, she added. Specifically, this will have a significant impact on patients with rheumatic disease.
Texas pharmacies target two drugs
MTX denials have caught the attention of health care organizations. “Uncertainty in financial and criminal liability for health care professionals in certain state laws and regulations are possibly compromising continuity of care and access [to] medications proven to be safe and effective by the Food and Drug Administration for these indications,” warned the American Pharmacists Association (APhA) in a statement to this news organization.
The APhA said that it was monitoring this situation to assess the effect on patients and pharmacists.
The Arthritis Foundation was made aware of challenges from patients in accessing their MTX prescription for managing their arthritis and shared a statement on the Foundation’s website.
In Texas, pharmacists can refuse to fill scripts for misoprostol and MTX, a combination used for medical abortions. According to the foundation, “Already there are reports that people in Texas who miscarry or take methotrexate for arthritis [are] having trouble getting their prescriptions filled.”
MTX, approved by the FDA in 1985, “is the absolute cornerstone of rheumatoid arthritis. We cannot deny our patients this incredibly valuable drug,” said John Reveille, MD, vice-chair for the department of medicine at the University of Texas McGovern School of Medicine and a member of the Arthritis Foundation expert panel, in an interview.
“While it’s true that methotrexate can be lethal to the fetus, misoprostol is much more likely to cause a spontaneous abortion, and the combination is especially effective,” he said.
“If you look at Cochrane clinical studies, the dose of misoprostol contained in certain combinations with NSAIDs [nonsteroidal anti-inflammatory drugs] can induce spontaneous abortions. It’s surprising that pharmacists are targeting methotrexate, an essential drug in arthritis treatment, when there are medications available that do not have this benefit that can by themselves cause loss of the fetus, such as mifepristone,” added Dr. Reveille.
The Dobbs ruling could also affect the ability of oncologists to provide lifesaving cancer care, according to Jason Westin, MD, an oncologist at the University of Texas MD Anderson Cancer Center in the department of lymphoma and myeloma.
“We have heard of medications with multiple indications, such as methotrexate, not being dispensed by pharmacies due to confusion regarding the intended use and potential consequences for the health care team,” he said in an interview.
Conflicting laws pose challenges for physicians
In North Dakota, inconsistencies in several laws are making it difficult for physicians and pharmacists to make decisions. “Lots of confusion can result when people pass laws against abortion. There’s sometimes no insight into the ramifications of those laws,” said Dr. Miller.
North Dakota approved a trigger law several years ago that makes abortion illegal 30 days after an overturning of Roe. However, another law that regulates abortion conflicts with the trigger law. “Some of the language will need clarification in the next legislative session,” he said.
APhA and other pharmacy associations strongly favor not interfering with the doctor- or pharmacist-patient relationship. The law needs to defer to appropriate care between doctor and patient, said Dr. Miller. State pharmacy associations in North Dakota are working with legislatures to clarify any exceptions in the law, he added.
Arizona lawmakers are trying to reconcile two abortion laws on the books. One, based on an 1864 territorial law, deems abortion illegal. In addition, a newly approved law bans abortions after 15 weeks. The latter will go into effect in September 2022. In both laws, a risk to the mother’s life is the only exception for abortion, said Dr. Young.
Denials aren’t widespread
Not all doctors are seeing MTX denials, but they’re worried about the future. “To date, we have not encountered difficulty in obtaining methotrexate based upon state abortion restrictions but are concerned that this could occur and result in dangerous delays in care,” said Dr. Westin.
Dr. Reveille, who practices rheumatology in Houston, has not yet received any complaints from patients. Things may be different in more rural parts of Texas, where pharmacists could be denying prescriptions based on religious issues, he offered.
It’s a little soon to see what repercussions may result from the Supreme Court ruling and state actions, said Dr. Reveille. “In Texas, we’re a bit ahead of the tidal wave.”
Access problems also haven’t shown up at the university clinic where Dr. Young practices. “In Arizona, it’s unclear if there would be a legal basis to refuse a person methotrexate on the basis that it can be used as an abortifacient,” she said.
Specificity is key in writing Rx scripts
Physicians can make things easier for patients by writing the indication and dose for the drug on the prescription slip. For example, a 10-mg script for MTX is not going to be used for an abortion, said Dr. Miller.
Rheumatologists in Texas have been doing this for some time, even before the Supreme Court ruling, said Fehmida Zahabi, MD, FACR, president of the Society of Texas Association of Rheumatology. For MTX prescriptions in premenopausal women, “patients are told their doctor needs to call the pharmacist. In the small print, we are asked to give a diagnosis to make sure we aren’t using it to terminate pregnancies,” said Dr. Zahabi.
She further noted that if the diagnosis is already indicated on the script, pharmacies generally won’t give patients a hard time.
Patients can also ask their physicians for a letter of medical necessity that confirms a drug’s use for a specific medical condition.
Mail order is another option if a local pharmacy won’t fill a prescription, said Dr. Miller. “This is legal unless a state makes it illegal to send an abortifacient across state lines,” he added.
Many medications used in rheumatic diseases are harmful in pregnancy, and it’s important to routinely discuss pregnancy risk and planning in the rheumatology clinic, said Dr. Young. This should include a thorough discussion and referral for long-acting reversible contraception in most cases, she suggested.
Actions at the federal, state level
President Joe Biden recently signed an executive order prompting federal regulators to protect access to medication abortions, among other steps to safeguard access to reproductive services.
In a statement on Twitter, the American College of Rheumatology (ACR) said that it was “ ... following this issue closely to determine if rheumatology providers and patients are experiencing any widespread difficulty accessing methotrexate or if any initial disruptions are potentially temporary and due to the independent actions of pharmacists trying to figure out what is and isn’t allowed where they practice.”
ACR has assembled a task force of medical and policy experts to determine the best course of action for patients.
The Arthritis Foundation also continues to monitor the situation, encouraging patients to call its hotline, said Steven Schultz, director of state legislative affairs, in an interview.
“We are analyzing how medication abortion could cause confusion on the part of providers or pharmacists dispensing the medication and what this means for specific patients,” said Mr. Schultz. Through a survey, the foundation hopes to get a better idea of what’s going on in the states at a macro level.
This may take some time, as states go through a process of lawsuits, injunctions, or coming into session to do something that may affect access to MTX, said Mr. Schultz.
Being involved in local advocacy is more important than ever, stressed Dr. Young. “Additionally, being plugged into what the ACR and other advocacy groups are doing on the national level is helpful as well to know the status of these medication access issues.”
Rheumatologists have a unique voice in this discussion, she added. “We guide our patients to stability for a safe pregnancy, and even with careful planning, we see patients who become critically ill during pregnancy and require lifesaving treatment, which at times can mean an abortion is necessary.”
Oncologists also advocate for their patients on a regular basis to make sure they have access to the care they need, said Dr. Westin. This situation with Roe is no different, he added. “We will continue to use our unique expertise to advocate for policies that assure access to high-quality, evidence-based care – and to help our patients overcome barriers that may interfere.”
Dr. Reveille participated on an advisory board with Eli Lilly in October 2021.

High deductible insurance linked to delayed advanced cancer diagnosis
In oncology, delayed care may result in a failed opportunity to achieve remission. Delays in diagnosis can result in patients having to undergo more extensive surgery, radiation exposure, or more intensive drug therapy than if their disease had been detected at an early stage.
Now, researchers at Harvard Medical School, Boston, report that
Using national insurance claims data, the authors conducted an observational study to examine what happened when some workers with employer-based insurance were switched from low-deductible to high-deductible plans, compared with a control group of workers who remained on low-deductible plans.
After the switch, workers shunted into high-deductible plans had a longer time to first diagnosis of a metastatic cancer, indicating delayed detection of advanced disease, compared with controls. The difference translated into a delay in diagnosis of metastatic disease of nearly 5 months, reported Nico Trad, BA, a fourth-year medical student at Dana-Farber Cancer Institute, Boston.
“The takeaway here is that these plans were associated with delayed detection of metastatic cancer. We did not assess the mechanism, but it’s a reasonable assumption to make that increased cost-sharing is having some adverse impacts on people’s willingness to seek care. And although we didn’t study potential impacts, we might anticipate that a delayed diagnosis might also lead to delayed engagement with palliative care,” he said in an oral abstract presentation at the annual meeting of the American Society of Clinical Oncology.
“A delay in initiation of symptom-relieving therapies and a delayed presentation might also lead to greater dissemination of disease throughout the body, which also has the potential to limit therapeutic options,” he added.
‘Deductible relief day’
Mr. Trad said that in 2022 more than half of employees are covered by high-deductible health plans, compared with only about 10% in 2006.
This major shift in cost burden coincided with President Joseph Biden’s announcement in early 2022 of the “Cancer Moonshot,” program with the goal of reducing cancer mortality by 50% over the next 25 years.
“Part of that is cancer prevention and control, which involves timely detection of cancer so that we can treat it early and have better outcomes,” he said.
High-deductible health plans ostensibly provide motivation for patients to shop for lower-priced care and avoid unnecessary or low-quality care, but making patients shell out more upfront before their insurance kicks in, while it reduced health care utilization, can also reduce the quality of care, he said.
In 2022, “Deductible Relief Day,” the day in which the average patient has satisfied the deductible and insurance starts to pick up more of the tab, occurred in mid-May, compared with late February in 2006.
Insurance claims data
Mr. Trad and colleagues used health insurance claims data from a nationally representative cohort of privately insured patients in a national commercial and Medicare Advantage database. They excluded patients 65 and older who were eligible for Medicare because it does not have high-deductible options.
The study cohort included 345,401 adults from the ages of 18 to 64 whose employers mandated a switch from a low-deductible plan which was defined as $500 or less, to a high-deductible plan defined as $1,000 or more. Controls were 1,654,775 contemporaneous adults whose employers offered only low-deductible plans. Both groups had a 1-year baseline period when all members were enrolled in low deductible plans.
To minimize the possibility of confounding, the investigators matched the participants by age, gender, race/ethnicity, morbidity according to Adjusted Clinical Group score, poverty level, geographic region, employer size, baseline primary cancer, baseline medical and pharmacy costs, and follow-up duration.
During the baseline period, the hazard ratio for time to a first observed metastatic cancer diagnosis in the main cohort, compared with controls, was 0.96 with a nonsignificant P value, indicating no difference in the time to diagnosis between the groups.
During a maximum 13.5 years of follow-up, however, the participants who had been switched after a year to a high-deductible plan had a significantly longer time to first metastatic diagnosis (HR, 0.88; P = .01), indicating delayed diagnosis relative to controls. This difference translated to a delay of 4.6 months associated with the higher out-of-pocket costs plans.
According to a systematic review and meta-analysis published online in 2020, a 1-month delay in treatment for many types of cancer can translate into a 6% to 13% higher risk for death, a risk that continues to increase with further delays.
The investigators acknowledged that the study was limited by the use of retrospective claims-based data, which not contain information on how the patients fared after diagnosis.
“I would say in terms of policy relevance that this really points to the need for new and innovative insurance models that, No. 1, reduce the cost-sharing burden for patients so that they’re not deterred from seeking care, and No. 2, that align rather than contradict the goal of improving population-level survival from cancer,” Mr. Trad said.
Further evidence of a flawed system
The study adds to an already strong body of evidence showing that high-deductible plans can have a negative impact on health, said Sara R. Collins, vice president for health care coverage and access at the Commonwealth Fund, a New York–based private foundation dedicated to improving health care.
“This is really the latest evidence on top of years of research that shows that high-deductible health plans lead people to make decisions that are not in the best interest of their health,” said Ms. Collins, who is not affiliated with the study presented at ASCO.
“We have a health care cost problem in the United States that far exceeds that of other high-income countries. Insurers try to solve it by shifting the costs to consumers and using other measures to restrict people’s use of health care, and often needed health care like this. The result is less access to needed care, and long-term adverse health consequences and their associated costs to patients and the health system generally,” she said.
The real driver of health care costs is not utilization, but the prices that insurers and providers negotiate in their service contracts, she explained.
“Prices are the central problem, insurers have control over those prices in their negotiations with providers. So unless we can gain control of that driver, patients are going to continue to suffer unnecessarily from both the short- and long-term effects of insurers who use tools to reduce their access to care,” she said.
In oncology, delayed care may result in a failed opportunity to achieve remission. Delays in diagnosis can result in patients having to undergo more extensive surgery, radiation exposure, or more intensive drug therapy than if their disease had been detected at an early stage.
Now, researchers at Harvard Medical School, Boston, report that
Using national insurance claims data, the authors conducted an observational study to examine what happened when some workers with employer-based insurance were switched from low-deductible to high-deductible plans, compared with a control group of workers who remained on low-deductible plans.
After the switch, workers shunted into high-deductible plans had a longer time to first diagnosis of a metastatic cancer, indicating delayed detection of advanced disease, compared with controls. The difference translated into a delay in diagnosis of metastatic disease of nearly 5 months, reported Nico Trad, BA, a fourth-year medical student at Dana-Farber Cancer Institute, Boston.
“The takeaway here is that these plans were associated with delayed detection of metastatic cancer. We did not assess the mechanism, but it’s a reasonable assumption to make that increased cost-sharing is having some adverse impacts on people’s willingness to seek care. And although we didn’t study potential impacts, we might anticipate that a delayed diagnosis might also lead to delayed engagement with palliative care,” he said in an oral abstract presentation at the annual meeting of the American Society of Clinical Oncology.
“A delay in initiation of symptom-relieving therapies and a delayed presentation might also lead to greater dissemination of disease throughout the body, which also has the potential to limit therapeutic options,” he added.
‘Deductible relief day’
Mr. Trad said that in 2022 more than half of employees are covered by high-deductible health plans, compared with only about 10% in 2006.
This major shift in cost burden coincided with President Joseph Biden’s announcement in early 2022 of the “Cancer Moonshot,” program with the goal of reducing cancer mortality by 50% over the next 25 years.
“Part of that is cancer prevention and control, which involves timely detection of cancer so that we can treat it early and have better outcomes,” he said.
High-deductible health plans ostensibly provide motivation for patients to shop for lower-priced care and avoid unnecessary or low-quality care, but making patients shell out more upfront before their insurance kicks in, while it reduced health care utilization, can also reduce the quality of care, he said.
In 2022, “Deductible Relief Day,” the day in which the average patient has satisfied the deductible and insurance starts to pick up more of the tab, occurred in mid-May, compared with late February in 2006.
Insurance claims data
Mr. Trad and colleagues used health insurance claims data from a nationally representative cohort of privately insured patients in a national commercial and Medicare Advantage database. They excluded patients 65 and older who were eligible for Medicare because it does not have high-deductible options.
The study cohort included 345,401 adults from the ages of 18 to 64 whose employers mandated a switch from a low-deductible plan which was defined as $500 or less, to a high-deductible plan defined as $1,000 or more. Controls were 1,654,775 contemporaneous adults whose employers offered only low-deductible plans. Both groups had a 1-year baseline period when all members were enrolled in low deductible plans.
To minimize the possibility of confounding, the investigators matched the participants by age, gender, race/ethnicity, morbidity according to Adjusted Clinical Group score, poverty level, geographic region, employer size, baseline primary cancer, baseline medical and pharmacy costs, and follow-up duration.
During the baseline period, the hazard ratio for time to a first observed metastatic cancer diagnosis in the main cohort, compared with controls, was 0.96 with a nonsignificant P value, indicating no difference in the time to diagnosis between the groups.
During a maximum 13.5 years of follow-up, however, the participants who had been switched after a year to a high-deductible plan had a significantly longer time to first metastatic diagnosis (HR, 0.88; P = .01), indicating delayed diagnosis relative to controls. This difference translated to a delay of 4.6 months associated with the higher out-of-pocket costs plans.
According to a systematic review and meta-analysis published online in 2020, a 1-month delay in treatment for many types of cancer can translate into a 6% to 13% higher risk for death, a risk that continues to increase with further delays.
The investigators acknowledged that the study was limited by the use of retrospective claims-based data, which not contain information on how the patients fared after diagnosis.
“I would say in terms of policy relevance that this really points to the need for new and innovative insurance models that, No. 1, reduce the cost-sharing burden for patients so that they’re not deterred from seeking care, and No. 2, that align rather than contradict the goal of improving population-level survival from cancer,” Mr. Trad said.
Further evidence of a flawed system
The study adds to an already strong body of evidence showing that high-deductible plans can have a negative impact on health, said Sara R. Collins, vice president for health care coverage and access at the Commonwealth Fund, a New York–based private foundation dedicated to improving health care.
“This is really the latest evidence on top of years of research that shows that high-deductible health plans lead people to make decisions that are not in the best interest of their health,” said Ms. Collins, who is not affiliated with the study presented at ASCO.
“We have a health care cost problem in the United States that far exceeds that of other high-income countries. Insurers try to solve it by shifting the costs to consumers and using other measures to restrict people’s use of health care, and often needed health care like this. The result is less access to needed care, and long-term adverse health consequences and their associated costs to patients and the health system generally,” she said.
The real driver of health care costs is not utilization, but the prices that insurers and providers negotiate in their service contracts, she explained.
“Prices are the central problem, insurers have control over those prices in their negotiations with providers.

FROM ASCO 2022
Transplanted pig hearts functioned normally in deceased persons on ventilator support
A team of surgeons successfully transplanted genetically engineered pig hearts into two recently deceased people whose bodies were being maintained on ventilatory support – not in the hope of restoring life, but as a proof-of-concept experiment in xenotransplantation that could eventually help to ease the critical shortage of donor organs.
The surgeries were performed on June 16 and July 6, 2022, using porcine hearts from animals genetically engineered to prevent organ rejection and promote adaptive immunity by human recipients
without utilizing unapproved devices or techniques or medications,” said Nader Moazami, MD, surgical director of heart transplantation and chief of the division of heart and lung transplantation and mechanical circulatory support at NYU Langone Health, New York.
Through 72 hours of postoperative monitoring “we evaluated the heart for functionality and the heart function was completely normal with excellent contractility,” he said at a press briefing announcing early results of the experimental program.
He acknowledged that for the first of the two procedures some surgical modification of the pig heart was required, primarily because of size differences between the donor and recipient.
“Nevertheless, we learned a tremendous amount from the first operation, and when that experience was translated into the second operation it even performed better,” he said.
Alex Reyentovich, MD, medical director of heart transplantation and director of the NYU Langone advanced heart failure program noted that “there are 6 million individuals with heart failure in the United States. About 100,000 of those individuals have end-stage heart failure, and we only do about 3,500 heart transplants a year in the United States, so we have a tremendous deficiency in organs, and there are many people dying waiting for a heart.”
Infection protocols
To date there has been only one xenotransplant of a genetically modified pig heart into a living human recipient, David Bennett Sr., age 57. The surgery, performed at the University of Maryland in January 2022, was initially successful, with the patient able to sit up in bed a few days after the procedure, and the heart performing like a “rock star” according to transplant surgeon Bartley Griffith, MD.
However, Mr. Bennett died 2 months after the procedure from compromise of the organ by an as yet undetermined cause, of which one may have been the heart's infection by porcine cytomegalovirus (CMV).
The NYU team, mindful of this potential setback, used more sensitive assays to screen the donor organs for porcine CMV, and implemented protocols to prevent and to monitor for potential zoonotic transmission of porcine endogenous retrovirus.
The procedure used a dedicated operating room and equipment that will not be used for clinical procedures, the team emphasized.
An organ transplant specialist who was not involved in the study commented that there can be unwelcome surprises even with the most rigorous infection prophylaxis protocols.
“I think these are important steps, but they don’t resolve the question of infectious risk. Sometimes viruses or latent infections are only manifested later,” said Jay A. Fishman, MD, associate director of the Massachusetts General Hospital Transplant Center and director of the transplant infectious diseases and compromised host program at the hospital, which is in Boston.
“I think these are important steps, but as you may recall from the Maryland heart transplant experience, when porcine cytomegalovirus was activated, it was a long way into that patient’s course, and so we just don’t know whether something would have been reactivated later,” he said in an interview.
Dr. Fishman noted that experience with xenotransplantation at the University of Maryland and other centers has suggested that immunosuppressive regimens used for human-to-human transplants may not be suited for animal-to-human grafts.
The hearts were taken from pigs genetically modified with knockouts of four porcine genes to prevent rejection – including a gene for a growth hormone that would otherwise cause the heart to continue to expand in the recipient’s chest – and with the addition of six human transgenes encoding for expression of proteins regulating biologic pathways that might be disrupted by incompatibilities across species.
Vietnam veteran
The organ recipients were recently deceased patients who had expressed the clear wish to be organ donors but whose organs were for clinical reasons unsuitable for transplant.
The first recipient was Lawrence Kelly, a Vietnam War veteran and welder who died from heart failure at the age of 72.
“He was an organ donor, and would be so happy to know how much his contribution to this research will help people like him with this heart disease. He was a hero his whole life, and he went out a hero,” said Alice Michael, Mr. Kelly’s partner of 33 years, who also spoke at the briefing.
“It was, I think, one of the most incredible things to see a pig heart pounding away and beating inside the chest of a human being,” said Robert A. Montgomery, MD, DPhil, director of the NYU Transplant Institute, and himself a heart transplant recipient.
Dr. Fishman said he had no relevant conflicts of interest.

Insulin Injection-Site Acanthosis Nigricans: Skin Reactions and Clinical Implications
Insulin injection therapy is one of the most widely used health care interventions to manage both type 1 and type 2 diabetes mellitus (T1DM/T2DM). Globally, more than 150 to 200 million people inject insulin into their upper posterior arms, buttocks, anterior and lateral thighs, or abdomen.1,2 In an ideal world, every patient would be using the correct site and rotating their insulin injection sites in accordance with health care professional (HCP) recommendations—systematic injections in one general body location, at least 1 cm away from the previous injection.2 Unfortunately, same-site insulin injection (repeatedly in the same region within 1 cm of previous injections) is a common mistake made by patients with DM—in one study, 63% of participants either did not rotate sites correctly or failed to do so at all.
Insulin-resistant cutaneous complications may occur as a result of same-site insulin injections. The most common is lipohypertrophy, reported in some studies in nearly 50% of patients with DM on insulin therapy.4 Other common cutaneous complications include lipoatrophy and amyloidosis. Injection-site acanthosis nigricans, although uncommon, has been reported in 18 cases in the literature.
Most articles suggest that same-site insulin injections decrease local insulin sensitivity and result in tissue hypertrophy because of the anabolic properties of insulin and increase in insulin binding to insulin-like growth factor-1 (IGF-1) receptor.5-20 The hyperkeratotic growth and varying insulin absorption rates associated with these cutaneous complications increase chances of either hyper- or hypoglycemic episodes in patients.10,11,13 It is the responsibility of the DM care professional to provide proper insulin-injection technique education and perform routine inspection of injection sites to reduce cutaneous complications of insulin therapy. The purpose of this article is to (1) describe a case of acanthosis nigricans resulting from insulin injection at the same site; (2) review case reports
Case Presentation
A 75-year-old patient with an 8-year history of T2DM, as well as stable coronary artery disease, atrial fibrillation, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and stage 3 chronic kidney disease, presented with 2 discrete abdominal hyperpigmented plaques. At the time of the initial clinic visit, the patient was taking metformin 1000 mg twice daily and insulin glargine 40 units once daily. When insulin was initiated 7 years prior, the patient received
The patient reported 5 years of progressive, asymptomatic hyperpigmentation of the skin surrounding his insulin glargine injection sites and injecting in these same sites daily without rotation. He reported no additional skin changes or symptoms. He had noticed no skin changes while using NPH insulin during his first year of insulin therapy. On examination, the abdominal wall skin demonstrated 2 well-demarcated, nearly black, soft, velvety plaques, measuring 9 × 8 cm on the left side and 4 × 3.5 cm on the right, suggesting acanthosis nigricans (Figure 1A). The remainder of the skin examination, including the flexures, was normal. Of note, the patient received biweekly intramuscular testosterone injections in the gluteal region for secondary hypogonadism with no adverse dermatologic effects. A skin punch biopsy was performed and revealed epidermal papillomatosis and hyperkeratosis, confirming the clinical diagnosis of acanthosis nigricans (Figure 2).
After a review of insulin-injection technique at his clinic visit, the patient started rotating insulin injection sites over his entire abdomen, and the acanthosis nigricans partially improved. A few months later, the patient stopped rotating the insulin injection site, and the acanthosis nigricans worsened again. Because of worsening glycemic control, the patient was then started on insulin aspart. He did not develop any skin changes at the insulin aspart injection site, although he was not rotating its site of injection.
Subsequently, with reeducation and proper injection-site rotation, the patient had resolution of his acanthosis nigricans (Figure 1b).
Discussion
A review of the literature revealed 18 reported cases of acanthosis nigricans at sites of repeated insulin injection (Table).5-20 Acanthosis nigricans at the site of insulin injection afflicts patients of any age, with cases observed in patients aged 14 to 75 years. Sixteen (84%) of 19 cases were male. Fourteen cases (73%) had T2DM; the rest of the patients had T1DM. The duration of insulin injection therapy prior to onset ranged from immediate to 13 years (median 4 years). Fourteen cases (73%) were reported on the abdomen; however, other sites, such as thighs and upper arm, also were reported. Lesions size varied from 12 to 360 cm2. Two cases had associated amyloidosis. The average HbA1c reported at presentation was 10%. Following insulin injection-site rotation, most of the cases reported improvement of both glycemic control and acanthosis nigricans appearance.
In the case described by Kudo and colleagues, a 59-year-old male patient with T2DM had been injecting insulin into the same spot on his abdomen for 10 years. He developed acanthosis nigricans and an amyloidoma so large and firm that it bent the needle when he injected insulin.11
Most of the cases we found in the literature were after 2005 and associated with the use of human or analog insulin. These cases may be related to a bias, as cases may be easier to find in digital archives in the later years, when human or analog insulins have been in common use. Also noteworthy, in cases that reported dosage, most were not very high, and the highest daily dose was 240 IU/d. Ten reports of injection-site acanthosis nigricans were in dermatology journals; only 5 reports were in endocrinology journals and 3 in general medical journals, indicating possible less awareness of this phenomenon in other HCPs who care for patients with DM.
Complications of Same-Site Injections
Acanthosis nigricans. Commonly found in the armpits, neck folds, and groin, acanthosis nigricans is known as one of the calling cards for insulin resistance, obesity, and hyperinsulinemia.21 Acanthosis nigricans can be seen in people with or without DM and is not limited to those on insulin therapy. However, same-site insulin injections for 4 to 6 years also may result in injection-site acanthosis nigricans–like lesions because of factors such as insulin exposure at the local tissue level.16
Acanthosis nigricans development is characterized by hyperpigmented, hyperkeratotic, velvety, and sometimes verrucous plaques.6 Acanthosis nigricans surrounding repeated injection sites is hypothesized to develop as a result of localized hyperinsulinemia secondary to insulin resistance, which increases the stimulation of IGF, thereby causing epidermal hypertrophy.5-20 If insulin injection therapy continues to be administered through the acanthosis nigricans lesion, it results in decreased insulin absorption, leading to poor glycemic control.13
Acanthosis nigricans associated with insulin injection is reversible. After rotation of injection sites, lesions either decrease in size or severity of appearance.5-8,11 Also, by avoiding injection into the hyperkeratotic plaques and using normal subcutaneous tissue for injection, patients’ response to insulin improves, as measured by HbA1c and by decreased daily insulin requirement.6-8,10,12,18-20
Lipohypertrophy. This is characterized by an increase in localized adipose tissue and is the most common cutaneous complication of insulin therapy.2 Lipohypertrophy presents as a firm, rubbery mass in the location of same-site insulin injections.22 Development of lipohypertrophy is suspected to be the result of either (1) anabolic effect of insulin on local adipocytes, promoting fat and protein synthesis; (2) an autoimmune response by immunoglobulin (Ig) G or IgE antibodies to insulin, immune response to insulin of different species, or to insulin injection techniques; or (3) repeated trauma to the injection site from repeated needle usage.4,23
In a study assessing the prevalence of lipohypertrophy and its relation to insulin technique, 49.1% of participants with
Primary prevention measures include injection site inspection and patient education about rotation and abstaining from needle reuse.22 If a patient already has signs of lipohypertrophy, data supports education and insulin injection technique practice as simple and effective means to reduce insulin action variability and increase glycemic control.24
Lipoatrophy. Lipoatrophy is described as a local loss of subcutaneous adipose tissue often in the face, buttocks, legs and arm regions and can be rooted in genetic, immune, or drug-associated etiologies.25 Insulin-induced lipoatrophy is suspected to be the result of tumor necrosis factor-α hyperproduction in reaction to insulin crystal presence at the injection site.26,27 Overall, lipoatrophy development has decreased since the use of recombinant human insulin and analog insulin therapy.28 The decrease is hypothesized to be due to increased subcutaneous tissue absorption rate of human insulin and its analog, decreasing overall adipocyte exposure to localized high insulin concentration.27 Treatments for same-site insulin-derived lipoatrophy include changing injection sites and preparation of insulin.26 When injection into the lipoatrophic site was avoided, glycemic control and lipoatrophy appearance improved.26
Amyloidosis. Amyloidosis indicates the presence of an extracellular bundle of insoluble polymeric protein fibrils in tissues and organs.29 Insulin-induced amyloidosis presents as a hard mass or ball near the injection site.29 Insulin is one of many hormones that can form amyloid fibrils, and there have been several dozen cases reported of amyloid formation at the site of insulin injection.29-31 Although insulin-derived amyloidosis is rare, it may be misdiagnosed as lipohypertrophy due to a lack of histopathologic testing or general awareness of the complication.29
In a case series of 7 patients with amyloidosis, all patients had a mean HbA1c of 9.3% (range, 8.5-10.2%) and averaged 1 IU/kg bodyweight before intervention.30 After the discovery of the mass, participants were instructed to avoid injection into the amyloidoma, and average insulin requirements decreased to 0.48 IU/kg body weight (P = .40).30 Patients with amyloidosis who rotated their injection sites experienced better glycemic control and decreased insulin requirements.30
Pathophysiology of Localized Insulin Resistance
Insulin regulates glucose homeostasis in skeletal muscle and adipose tissue, increases hepatic and adipocyte lipid synthesis, and decreases adipocyte fatty acid release.32 Generalized insulin resistance occurs when target tissues have decreased glucose uptake in response to circulating insulin.32 Insulin resistance increases the amount of free insulin in surrounding tissues. At high concentrations, insulin fosters tissue growth by binding to IGF-1 receptors, stimulating hypertrophy and reproduction of keratinocytes and fibroblasts.33 This pathophysiology helps explain the origin of localized acanthosis nigricans at same-site insulin injections.
Conclusions
Cutaneous complications are a local adverse effect of long-term failure to rotate insulin injection sites. Our case serves as a call to action for HCPs to improve education regarding insulin injection-site rotation, conduct routine injection-site inspection, and actively document cases as they occur to increase public awareness of these important complications.
If a patient with DM presents with unexplained poor glycemic control, consider questioning the patient about injection-site location and how often they are rotating the insulin injection site. Inspect the site for cutaneous complications. Of note, if a patient has a cutaneous complication due to insulin injection, adjust or decrease the insulin dosage when rotating sites to mitigate the risk of hypoglycemic episodes.
Improvement of glycemic control, cosmetic appearance of injection site, and insulin use all begin with skin inspection, injection technique education, and periodic review by a HCP.

Insulin injection therapy is one of the most widely used health care interventions to manage both type 1 and type 2 diabetes mellitus (T1DM/T2DM). Globally, more than 150 to 200 million people inject insulin into their upper posterior arms, buttocks, anterior and lateral thighs, or abdomen.1,2 In an ideal world, every patient would be using the correct site and rotating their insulin injection sites in accordance with health care professional (HCP) recommendations—systematic injections in one general body location, at least 1 cm away from the previous injection.2 Unfortunately, same-site insulin injection (repeatedly in the same region within 1 cm of previous injections) is a common mistake made by patients with DM—in one study, 63% of participants either did not rotate sites correctly or failed to do so at all.
Insulin-resistant cutaneous complications may occur as a result of same-site insulin injections. The most common is lipohypertrophy, reported in some studies in nearly 50% of patients with DM on insulin therapy.4 Other common cutaneous complications include lipoatrophy and amyloidosis. Injection-site acanthosis nigricans, although uncommon, has been reported in 18 cases in the literature.
Most articles suggest that same-site insulin injections decrease local insulin sensitivity and result in tissue hypertrophy because of the anabolic properties of insulin and increase in insulin binding to insulin-like growth factor-1 (IGF-1) receptor.5-20 The hyperkeratotic growth and varying insulin absorption rates associated with these cutaneous complications increase chances of either hyper- or hypoglycemic episodes in patients.10,11,13 It is the responsibility of the DM care professional to provide proper insulin-injection technique education and perform routine inspection of injection sites to reduce cutaneous complications of insulin therapy. The purpose of this article is to (1) describe a case of acanthosis nigricans resulting from insulin injection at the same site; (2) review case reports
Case Presentation
A 75-year-old patient with an 8-year history of T2DM, as well as stable coronary artery disease, atrial fibrillation, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and stage 3 chronic kidney disease, presented with 2 discrete abdominal hyperpigmented plaques. At the time of the initial clinic visit, the patient was taking metformin 1000 mg twice daily and insulin glargine 40 units once daily. When insulin was initiated 7 years prior, the patient received
The patient reported 5 years of progressive, asymptomatic hyperpigmentation of the skin surrounding his insulin glargine injection sites and injecting in these same sites daily without rotation. He reported no additional skin changes or symptoms. He had noticed no skin changes while using NPH insulin during his first year of insulin therapy. On examination, the abdominal wall skin demonstrated 2 well-demarcated, nearly black, soft, velvety plaques, measuring 9 × 8 cm on the left side and 4 × 3.5 cm on the right, suggesting acanthosis nigricans (Figure 1A). The remainder of the skin examination, including the flexures, was normal. Of note, the patient received biweekly intramuscular testosterone injections in the gluteal region for secondary hypogonadism with no adverse dermatologic effects. A skin punch biopsy was performed and revealed epidermal papillomatosis and hyperkeratosis, confirming the clinical diagnosis of acanthosis nigricans (Figure 2).
After a review of insulin-injection technique at his clinic visit, the patient started rotating insulin injection sites over his entire abdomen, and the acanthosis nigricans partially improved. A few months later, the patient stopped rotating the insulin injection site, and the acanthosis nigricans worsened again. Because of worsening glycemic control, the patient was then started on insulin aspart. He did not develop any skin changes at the insulin aspart injection site, although he was not rotating its site of injection.
Subsequently, with reeducation and proper injection-site rotation, the patient had resolution of his acanthosis nigricans (Figure 1b).
Discussion
A review of the literature revealed 18 reported cases of acanthosis nigricans at sites of repeated insulin injection (Table).5-20 Acanthosis nigricans at the site of insulin injection afflicts patients of any age, with cases observed in patients aged 14 to 75 years. Sixteen (84%) of 19 cases were male. Fourteen cases (73%) had T2DM; the rest of the patients had T1DM. The duration of insulin injection therapy prior to onset ranged from immediate to 13 years (median 4 years). Fourteen cases (73%) were reported on the abdomen; however, other sites, such as thighs and upper arm, also were reported. Lesions size varied from 12 to 360 cm2. Two cases had associated amyloidosis. The average HbA1c reported at presentation was 10%. Following insulin injection-site rotation, most of the cases reported improvement of both glycemic control and acanthosis nigricans appearance.
In the case described by Kudo and colleagues, a 59-year-old male patient with T2DM had been injecting insulin into the same spot on his abdomen for 10 years. He developed acanthosis nigricans and an amyloidoma so large and firm that it bent the needle when he injected insulin.11
Most of the cases we found in the literature were after 2005 and associated with the use of human or analog insulin. These cases may be related to a bias, as cases may be easier to find in digital archives in the later years, when human or analog insulins have been in common use. Also noteworthy, in cases that reported dosage, most were not very high, and the highest daily dose was 240 IU/d. Ten reports of injection-site acanthosis nigricans were in dermatology journals; only 5 reports were in endocrinology journals and 3 in general medical journals, indicating possible less awareness of this phenomenon in other HCPs who care for patients with DM.
Complications of Same-Site Injections
Acanthosis nigricans. Commonly found in the armpits, neck folds, and groin, acanthosis nigricans is known as one of the calling cards for insulin resistance, obesity, and hyperinsulinemia.21 Acanthosis nigricans can be seen in people with or without DM and is not limited to those on insulin therapy. However, same-site insulin injections for 4 to 6 years also may result in injection-site acanthosis nigricans–like lesions because of factors such as insulin exposure at the local tissue level.16
Acanthosis nigricans development is characterized by hyperpigmented, hyperkeratotic, velvety, and sometimes verrucous plaques.6 Acanthosis nigricans surrounding repeated injection sites is hypothesized to develop as a result of localized hyperinsulinemia secondary to insulin resistance, which increases the stimulation of IGF, thereby causing epidermal hypertrophy.5-20 If insulin injection therapy continues to be administered through the acanthosis nigricans lesion, it results in decreased insulin absorption, leading to poor glycemic control.13
Acanthosis nigricans associated with insulin injection is reversible. After rotation of injection sites, lesions either decrease in size or severity of appearance.5-8,11 Also, by avoiding injection into the hyperkeratotic plaques and using normal subcutaneous tissue for injection, patients’ response to insulin improves, as measured by HbA1c and by decreased daily insulin requirement.6-8,10,12,18-20
Lipohypertrophy. This is characterized by an increase in localized adipose tissue and is the most common cutaneous complication of insulin therapy.2 Lipohypertrophy presents as a firm, rubbery mass in the location of same-site insulin injections.22 Development of lipohypertrophy is suspected to be the result of either (1) anabolic effect of insulin on local adipocytes, promoting fat and protein synthesis; (2) an autoimmune response by immunoglobulin (Ig) G or IgE antibodies to insulin, immune response to insulin of different species, or to insulin injection techniques; or (3) repeated trauma to the injection site from repeated needle usage.4,23

In a case series of 7 patients with amyloidosis, all patients had a mean HbA1c of 9.3% (range, 8.5-10.2%) and averaged 1 IU/kg bodyweight before intervention.30 After the discovery of the mass, participants were instructed to avoid injection into the amyloidoma, and average insulin requirements decreased to 0.48 IU/kg body weight (P = .40).30 Patients with amyloidosis who rotated their injection sites experienced better glycemic control and decreased insulin requirements.30

Lipoatrophy is described as a local loss of subcutaneous adipose tissue often in the face, buttocks, legs and arm regions and can be rooted in genetic, immune, or drug-associated etiologies.25 Insulin-induced lipoatrophy is suspected to be the result of tumor necrosis factor-α hyperproduction in reaction to insulin crystal presence at the injection site.26,27 Overall, lipoatrophy development has decreased since the use of recombinant human insulin and analog insulin therapy.28 The decrease is hypothesized to be due to increased subcutaneous tissue absorption rate of human insulin and its analog, decreasing overall adipocyte exposure to localized high insulin concentration.27 Treatments for same-site insulin-derived lipoatrophy include changing injection sites and preparation of insulin.26 When injection into the lipoatrophic site was avoided, glycemic control and lipoatrophy appearance improved.26
Amyloidosis. Amyloidosis indicates the presence of an extracellular bundle of insoluble polymeric protein fibrils in tissues and organs.29 Insulin-induced amyloidosis presents as a hard mass or ball near the injection site.29 Insulin is one of many hormones that can form amyloid fibrils, and there have been several dozen cases reported of amyloid formation at the site of insulin injection.29-31 Although insulin-derived amyloidosis is rare, it may be misdiagnosed as lipohypertrophy due to a lack of histopathologic testing or general awareness of the complication.29
In a case series of 7 patients with amyloidosis, all patients had a mean HbA1c of 9.3% (range, 8.5-10.2%) and averaged 1 IU/kg bodyweight before intervention.30 After the discovery of the mass, participants were instructed to avoid injection into the amyloidoma, and average insulin requirements decreased to 0.48 IU/kg body weight (P = .40).30 Patients with amyloidosis who rotated their injection sites experienced better glycemic control and decreased insulin requirements.30
Pathophysiology of Localized Insulin Resistance
Insulin regulates glucose homeostasis in skeletal muscle and adipose tissue, increases hepatic and adipocyte lipid synthesis, and decreases adipocyte fatty acid release.32 Generalized insulin resistance occurs when target tissues have decreased glucose uptake in response to circulating insulin.32 Insulin resistance increases the amount of free insulin in surrounding tissues. At high concentrations, insulin fosters tissue growth by binding to IGF-1 receptors, stimulating hypertrophy and reproduction of keratinocytes and fibroblasts.33 This pathophysiology helps explain the origin of localized acanthosis nigricans at same-site insulin injections.
Conclusions
Cutaneous complications are a local adverse effect of long-term failure to rotate insulin injection sites. Our case serves as a call to action for HCPs to improve education regarding insulin injection-site rotation, conduct routine injection-site inspection, and actively document cases as they occur to increase public awareness of these important complications.
If a patient with DM presents with unexplained poor glycemic control, consider questioning the patient about injection-site location and how often they are rotating the insulin injection site. Inspect the site for cutaneous complications. Of note, if a patient has a cutaneous complication due to insulin injection, adjust or decrease the insulin dosage when rotating sites to mitigate the risk of hypoglycemic episodes.
Improvement of glycemic control, cosmetic appearance of injection site, and insulin use all begin with skin inspection, injection technique education, and periodic review by a HCP.

Large study reaffirms rare risk of TNF inhibitor–induced psoriasis in patients with RA, IBD
according to a new study published in JAMA Dermatology.
Despite this finding, the authors of the large Danish nationwide cohort study noted that TNFi-induced psoriasis is still a rare adverse event. “Practitioners and patients should be aware and observant of the potential for TNFi-associated psoriasis during TNFi treatment but keep in mind that the absolute risk appears to be low,” David Thein, MB, of the department of dermatology at Bispebjerg Hospital, University of Copenhagen, and colleagues wrote in the study.
They analyzed 109,085 patients with RA and IBD enrolled in Danish national registries between 1995 and 2018 without a previous diagnosis of psoriasis, who received either TNFi (20,910 patients) or conventional treatments (108,024 patients) and were followed for 5 years. They were a mean of 50 years old when they started treatment, 62% were women, with 87.8% of patients in the TNFi group receiving prior conventional therapy and 1% of patients in the conventional therapy group receiving prior TNFi treatment.
The investigators assessed the risk of developing any psoriasis, nonpustular psoriasis, and pustular psoriasis in the two groups using ICD-10 codes as well as a record of two consecutive prescriptions for topical vitamin D analogs.
Overall, 1,471 patients (1.4%) developed psoriasis of any type; 1,332 had non-pustular psoriasis, 127 had palmoplantar pustulosis, and 12 had generalized pustulosis.
The incidence rate of developing any psoriasis was 3.0 per 1,000 patient-years (95% confidence interval, 2.9-3.2) for patients receiving conventional therapy and 7.8 per 1,000 patient-years (95% CI, 7.5-8.9) for patients receiving TNFi treatment. Compared with conventional treatment, the risk of developing nonpustular psoriasis was twofold higher among patients receiving TNFi treatment (hazard ratio, 2.12; 95% CI, 1.87-2.40; P < .001). The risk of developing pustular psoriasis was more than sixfold higher among those on a TNFi (HR, 6.50; 95% CI, 4.60-9.23; P < .001).
Dr. Thein and colleagues estimated that the exposure needed to harm 1 additional patient was 241 patient-years for any psoriasis type, 342 patient-years for nonpustular psoriasis, and 909 patient-years for pustular psoriasis, with an estimated absolute risk difference of 5 per 1,000 patient-years.
Best evidence to date on risk
Asked to comment on the study findings, Anthony Fernandez, MD, PhD, director of medical dermatology at the Cleveland Clinic, said that he applauded the researchers for performing this well-designed study to determine the risk of TNF inhibitor–induced psoriasis in patients with RA and IBD.
The strengths of the study include excluding patients with a history of psoriasis to rule out disease recurrence and having a large comparator group of patients with IBD and RA who were taking medications other than TNF inhibitors, while one limitation was the potential accuracy of the ICD-10 codes used as the basis for diagnosing psoriasis. “It’s probably closer to the truth of what the true risk is compared to studies done in the past,” he said in an interview.
Dr. Fernandez noted that the results aren’t likely to change how dermatologists, rheumatologists, or gastroenterologists practice, but the message to stay the course in initially treating TNFi-induced psoriasis also holds value. “We don’t need to change anything in our clinical practice when it comes to TNF-alpha inhibitors.”
For patients with RA or IBD who develop TNFi-induced psoriasis with disease that is well controlled with TNFi treatment, keeping them on that treatment is a priority, Dr. Fernandez explained. “The first and foremost goal is, if the TNF inhibitor is working very well to control the disease that it was prescribed for, then you exhaust your efforts to try to control the psoriasis and allow those patients to stay on the TNF inhibitor.”
In his experience, most patients with RA and IBD who develop TNFi-induced psoriasis are controlled with topical medications. Switching to another TNFi is not recommended, he noted, as patients are “likely to have that reaction with any TNF inhibitor.”
However, Dr. Fernandez said that won’t be an option for all patients with RA and IBD. “In some patients you do simply have to stop the TNF inhibitor” and try an alternative treatment with a different mechanism of action.
The cause of TNFi-induced psoriasis is still not well understood. “There certainly is evidence to support that interferon alpha production by plasmacytoid dendritic cells is playing some role in this phenomenon,” but there is “more to the story” and unanswered questions remain, Dr. Fernandez said.
What’s most interesting about this phenomenon, he added, is that “patients can develop it at any time when exposed to a TNF inhibitor.” For instance, most patients develop drug reactions within 2-3 weeks of starting a treatment, but TNFi-induced psoriasis can appear after a single dose or several years after initiating treatment.
“Why so few patients, and why is there such variability in terms of how long they’re on the TNF inhibitor before the reaction occurs?” he asked. “That really points to ... some other trigger besides exposure to the TNF inhibitor needed for the initiation of this reaction.”
He noted that it would be valuable to identify triggers – or the most likely triggers – which would be challenging, but could “potentially impact clinical practice.”
The authors reported personal and institutional relationships in the form of personal and institutional research grants, honoraria, personal fees, investigator fees paid to university, consultancies, and speaker’s bureau positions for a variety of pharmaceutical companies, data companies, hospitals, and foundations. Dr. Fernandez reported he has nonbranded speaking, consulting, and research relationships with AbbVie and Novartis; and is a consultant for UCB, Bristol-Myers Squibb, and Boehringer Ingelheim on related products.

Dr. Fernandez noted that the results aren’t likely to change how dermatologists, rheumatologists, or gastroenterologists practice, but the message to stay the course in initially treating TNFi-induced psoriasis also holds value. “We don’t need to change anything in our clinical practice when it comes to TNF-alpha inhibitors.”
For patients with RA or IBD who develop TNFi-induced psoriasis with disease that is well controlled with TNFi treatment, keeping them on that treatment is a priority, Dr. Fernandez explained. “The first and foremost goal is, if the TNF inhibitor is working very well to control the disease that it was prescribed for, then you exhaust your efforts to try to control the psoriasis and allow those patients to stay on the TNF inhibitor.”
In his experience, most patients with RA and IBD who develop TNFi-induced psoriasis are controlled with topical medications. Switching to another TNFi is not recommended, he noted, as patients are “likely to have that reaction with any TNF inhibitor.”
However, Dr. Fernandez said that won’t be an option for all patients with RA and IBD. “In some patients you do simply have to stop the TNF inhibitor” and try an alternative treatment with a different mechanism of action.
The cause of TNFi-induced psoriasis is still not well understood. “There certainly is evidence to support that interferon alpha production by plasmacytoid dendritic cells is playing some role in this phenomenon,” but there is “more to the story” and unanswered questions remain, Dr. Fernandez said.
What’s most interesting about this phenomenon, he added, is that “patients can develop it at any time when exposed to a TNF inhibitor.” For instance, most patients develop drug reactions within 2-3 weeks of starting a treatment, but TNFi-induced psoriasis can appear after a single dose or several years after initiating treatment.
“Why so few patients, and why is there such variability in terms of how long they’re on the TNF inhibitor before the reaction occurs?” he asked. “That really points to ... some other trigger besides exposure to the TNF inhibitor needed for the initiation of this reaction.”
He noted that it would be valuable to identify triggers – or the most likely triggers – which would be challenging, but could “potentially impact clinical practice.”
The authors reported personal and institutional relationships in the form of personal and institutional research grants, honoraria, personal fees, investigator fees paid to university, consultancies, and speaker’s bureau positions for a variety of pharmaceutical companies, data companies, hospitals, and foundations. Dr. Fernandez reported he has nonbranded speaking, consulting, and research relationships with AbbVie and Novartis; and is a consultant for UCB, Bristol-Myers Squibb, and Boehringer Ingelheim on related products.
according to a new study published in JAMA Dermatology.
Despite this finding, the authors of the large Danish nationwide cohort study noted that TNFi-induced psoriasis is still a rare adverse event. “Practitioners and patients should be aware and observant of the potential for TNFi-associated psoriasis during TNFi treatment but keep in mind that the absolute risk appears to be low,” David Thein, MB, of the department of dermatology at Bispebjerg Hospital, University of Copenhagen, and colleagues wrote in the study.
They analyzed 109,085 patients with RA and IBD enrolled in Danish national registries between 1995 and 2018 without a previous diagnosis of psoriasis, who received either TNFi (20,910 patients) or conventional treatments (108,024 patients) and were followed for 5 years. They were a mean of 50 years old when they started treatment, 62% were women, with 87.8% of patients in the TNFi group receiving prior conventional therapy and 1% of patients in the conventional therapy group receiving prior TNFi treatment.
The investigators assessed the risk of developing any psoriasis, nonpustular psoriasis, and pustular psoriasis in the two groups using ICD-10 codes as well as a record of two consecutive prescriptions for topical vitamin D analogs.
Overall, 1,471 patients (1.4%) developed psoriasis of any type; 1,332 had non-pustular psoriasis, 127 had palmoplantar pustulosis, and 12 had generalized pustulosis.
The incidence rate of developing any psoriasis was 3.0 per 1,000 patient-years (95% confidence interval, 2.9-3.2) for patients receiving conventional therapy and 7.8 per 1,000 patient-years (95% CI, 7.5-8.9) for patients receiving TNFi treatment. Compared with conventional treatment, the risk of developing nonpustular psoriasis was twofold higher among patients receiving TNFi treatment (hazard ratio, 2.12; 95% CI, 1.87-2.40; P < .001). The risk of developing pustular psoriasis was more than sixfold higher among those on a TNFi (HR, 6.50; 95% CI, 4.60-9.23; P < .001).
Dr. Thein and colleagues estimated that the exposure needed to harm 1 additional patient was 241 patient-years for any psoriasis type, 342 patient-years for nonpustular psoriasis, and 909 patient-years for pustular psoriasis, with an estimated absolute risk difference of 5 per 1,000 patient-years.

If nuclear disaster strikes, U.S. hematologists stand ready
For many Americans – especially those too young to know much about the Cold War or Hiroshima – Russia’s invasion of Ukraine might mark the first time they’ve truly considered the dangers of nuclear weapons. But dozens of hematologists in the United States already know the drill and have placed themselves on the front lines. These physicians stand prepared to treat patients exposed to radiation caused by nuclear accidents or attacks on U.S. soil.
They work nationwide at 74 medical centers that make up the Radiation Injury Treatment Network, ready to manage cases of acute radiation syndrome (ARS) during disasters. While RITN keeps a low profile, it’s been in the news lately amid anxieties about the Ukraine conflict, nuclear plant accidents, and the potential launching of nuclear weapons by foreign adversaries.
“The Radiation Injury Treatment Network helps plan responses for disaster scenarios where a person’s cells would be damaged after having been exposed to ionizing radiation,” program director Cullen Case Jr., MPA, said in an interview.
A U.S. Army veteran who took part in hurricane response early in his career, Mr. Case now oversees preparedness activities among all RITN hospitals, blood donor centers, and cord blood banks, in readiness for a mass casualty radiological incident. He also serves as a senior manager of the National Marrow Donor Program/Be a Match Marrow Registry.
Intense preparation for nuclear attacks or accidents is necessary, Mr. Case said, despite the doomsday scenarios disseminated on television shows and movies.
“The most frequent misconception we hear is that a nuclear disaster will encompass the whole world and be so complete that preparedness isn’t useful. However, many planning scenarios include smaller-scale incidents where survivors will need prompt and expert care,” he said.
In the wake of 9/11, the National Marrow Donor Program and the American Society for Blood and Marrow Transplantation established the RITN in 2006, with a mission to prepare for nuclear disaster and help manage the response if one occurs.
“The widespread availability of radioactive material has made future exposure events, accidental or intentional, nearly inevitable,” RITN leaders warned in a 2008 report. “Hematologists, oncologists, and HSCT [hematopoietic stem cell transplantation] physicians are uniquely suited to care for victims of radiation exposure, creating a collective responsibility to prepare for a variety of contingencies.”
RITN doesn’t just train physicians, Mr. Case noted. All medical centers within the RITN are required to conduct an annual tabletop exercise where a radiation disaster scenario and a set of discussion questions are presented to the team.
Hematologists specially equipped to treat radiation injuries
Why are hematologists involved in treating people exposed to dangerously high levels of radiation? The answer has to do with how radiation harms the body, said Dr. Ann A. Jakubowski, a hematologist/oncologist and transplant physician at Memorial Sloan Kettering Cancer Center, New York, who serves as a medical director for RITN.
“One of the most common toxicities from radiation exposure and a major player in acute radiation syndrome is hematologic toxicity– damage to the bone marrow by the radiation, with a resultant decrease in peripheral blood counts,” she said in an interview. “This is similar to what is often seen in the treatment of cancers with radiation and/or chemotherapy.”
In cases of severe and nonreversible radiation damage to the bone marrow, Dr. Jakubowski noted, “patients can be considered for a stem cell transplant to provide new healthy cells to repopulate the bone marrow, which provides recovery of peripheral blood counts. Hematologist/oncologists are the physicians who manage stem cell transplants.”
The crucial role of hematologists in radiation injuries is not new. In fact, these physicians have been closely intertwined with nuclear research since the dawn of the atomic age. The work of developing atomic bombs also led investigators to an understanding of the structure and processes of hematopoiesis and helped them to identify hematopoietic stem cells and prove their existence in humans.
Disaster response poses multiple challenges
As noted in a recent article in ASH Clinical News, the challenges of treating radiation injuries would be intense, especially in the event of a nuclear accident or attack that affects a wide area. For starters, how quickly can medical professionals be mobilized, and will there be enough physicians comfortable treating patients? Fortunately, irradiated patients should not pose a direct risk to medical professionals who treat them.
“The expectation is that the patients will all be decontaminated,” said Nelson Chao, MD, MBA, one of the founders of RITN and a hematologist/oncologist and transplant physician at Duke University, Durham, N.C.
Dr. Jakubowski questions whether there will be adequate resources to handle the influx of patients who need more intensive treatment, as well as outpatients who “received lower doses of radiation and may experience a period of low blood counts but are expected to eventually recover blood counts.”
And if many people are injured, Dr. Chao asks, how will physicians “adopt altered standards of care to treat large numbers of patients?”
There will also be a need for physicians who aren’t hematologists, Dr. Jakubowski said. “There may be many victims who have both radiation exposure and traumatic or burn injuries, which need to be addressed first, before the hematologist can start addressing the consequences of ARS. Traumatic and burn injuries will require surgical resources.”
In addition, ARS affects the gastrointestinal track and central nervous system/cardiovascular, and it has multiple stages, she noted.
“Although we have methods of supporting the hematopoietic system – transfusions and growth factors – and even replacing it with a stem cell transplant, this will not necessarily fix the badly damaged other organs, Dr. Jakubowski said. “Also, not all radioactive isotopes are equal in their effects, nor are the various types of radiation exposure.”
Training goes beyond transplants and drugs
RITN offers individual hematologists specialized education about treating radiation injuries through annual exercises, modules, and “just-in-time” training.
For example, the RITN webpage devoted to triage includes guidelines for transferring radiation injury patients, triage guidelines for cytokine administration in cases of ARS, an exposure and symptom triage tool, and more. The treatment page includes details about subjects such as when human leukocyte antigen typing of casualties is appropriate and how to keep yourself safe while treating patients.
Another focus is teaching hematologists to react quickly in disasters, Mr. Case said. “The vast majority of hematologists have little to no experience in responding to disasters and making decisions with imperfect or incomplete information, as emergency medicine practitioners must do regularly.”
“Some of the RITN tabletop exercises present physicians and advanced practitioners with an incomplete set of patient information and ask physicians to then determine and prioritize their care,” Mr. Case said. “The resulting discussions help to lay the groundwork for being able to shift to the crisis standards of care mindset that would be necessary during a radiological disaster.”
Here’s how hematologists can get involved
If you want to help improve the nation’s response to radiation injuries, Mr. Case suggests checking RITN’s list of participating hospitals. If your facility is already part of this network, he said, contact its bone marrow transplant unit for more information.
In such cases, Dr. Jakubowski suggests that you “consider periodically giving a presentation to staff on the basics of radiation injury and the center’s role in RITN.” And if you’re not part of RITN, she said, consider contacting the network about becoming a member.
Hematologists, Mr. Case said, can also take advantage of RITN’s free short overview courses, review the RITN Treatment Guidelines, or watch short videos on the RITN’s YouTube channel.
He highlighted the Radiation Emergency Medical Management website administered by the Department of Health & Human Services, the Center for Disease Control’s radiation emergencies webpage, and the Department of Energy’s Radiation Emergency Assistance Center/Training Site.

U.K. survey: Dermatologists want training in prescribing antipsychotics for delusional infestation
GLASGOW – that also indicated there is a clear demand for training in prescribing these drugs.
Delusional infestation is a rare disorder characterized by an individual’s belief that his or her skin, body, or immediate environment is infested by small, living pathogens, despite a lack of any medical evidence. Most of these patients require antipsychotic medication to alleviate symptoms.
The survey of almost 80 dermatologists found that almost 90% had not prescribed antipsychotics in the previous month for patients with psychodermatology conditions and that the most common barrier to prescribing was lack of experience with the drugs.
This was reflected in only 10% of survey respondents who said they were “happy to” prescribe antipsychotics without consulting either dermatology or psychiatric colleagues, and less than half having attended a related course.
Yet the research, presented at the annual meeting of the British Association of Dermatologists, indicated that more than 75% of respondents would attend such a course to increase their confidence.
This finding, said study presenter Ling Li, MD, Churchill Hospital, Oxford (England) University Hospitals NHS Foundation Trust, shows that there is a “clear demand for training, particularly among all the registrars [residents] who we surveyed.”
Dr. Li noted that the UK’s Joint Royal Colleges of Physicians Training Board’s latest curriculum for dermatology training highlights psychocutaneous medicine as a key area, and “that will include antipsychotic medication.”
The BAD also recently published guidelines for the management of adults with delusional infestation, which includes a recommendation to conduct a survey on attitudes toward antipsychotic prescribing for the condition among U.K. dermatologists.
Heeding that call, Dr. Li and colleagues sent an email containing a 10-question online survey to members of the BAD and the British Society for Medical Dermatology. Questions covered familiarity with antipsychotics and frequency of prescribing, confidence around antipsychotics, and current training and future needs. Responses were received between February through April 2021.
Among the 79 respondents, 51 (65%) were consultants and 20 (25%) were dermatology registrars, with the remainder dermatology clinical fellows, foundation doctors, or other doctors. A total of 31 respondents had an average of more than 50 visits with patients per week, 18 had an average of 41-50 patient visits, and 13 had an average of 31-40 visits per week; the remainder had an average of 11-30 visits per week.
Most of the respondents (39) said they had seen 2-5 patients with psychodermatology conditions in the last 6 months, while 17 said they had seen 1 patient, 13 said they had seen more than 10 patients, and 6 said they had seen 6-10 patients (4 had seen none and 1 could not remember).
The most commonly prescribed antipsychotics for psychodermatology patients in the past 6 months were risperidone (Risperdal; prescribed by five respondents), followed by olanzapine (Zyprexa; by four respondents). Seventy respondents had not prescribed any antipsychotics.
Asked about how confident they felt about prescribing antipsychotic medication for patients with delusional infestation, 8 (10%) said they were happy to prescribe independently, while 42 (54%) said they were not at all confident. Another 10 (13%) respondents said they would be happy to prescribe the medications after liaising with a dermatology colleague, while 17 (22%) said they would prefer to consult with the psychiatry team.
The most common barrier to prescribing antipsychotic medications was a lack of experience with the drugs, cited by 66 respondents, followed by concerns over drug monitoring, cited by 43 respondents.
In addition, 42 respondents highlighted concerns over adverse effects, 36 cited lack of experience in psychodermatology clinics, and 19 cited lack of experience in discussing psychodermatologic conditions with patients. Other barriers mentioned by the respondents included difficulties with patient acceptance of a psychiatric medication prescribed by a dermatologist.
An audience member went further, saying that clinicians have been told not to “confront” such patients and that the temptation is therefore to cloak the discussion of antipsychotics in nonthreatening language so that it is more acceptable to the patient.
However, under the U.K. system, a letter with the results of the consultation, including information that an antipsychotic has been prescribed, must be sent to the patient’s family doctor along with a copy that goes to the patient. “The situation is almost impossible,” the audience member said, adding that there “must be some arrangement where in certain circumstances dermatologists could be allowed not to write to the patient” or alternatively, “write an entirely different letter” to the family doctor.
Session cochair Susannah Baron, MD, a consultant dermatologist at St. John’s Institute of Dermatology, Guy’s and St. Thomas’ Hospital, London, said that, in these situations, it is “really helpful to talk about doses” with patients.
She explained that she uses the analogy of aspirin, which has different effects depending on the dose given, giving pain relief at high doses but primarily an antiplatelet effect at low doses.
In the case of an antipsychotic, it is helpful to explain to the patient that “you don’t think they’re psychotic, and you’re prescribing it in a very low dose, because what it can do is help with their symptoms,” Dr. Baron added. “You have to be very open because if you’re not, they go to the pharmacy, and the pharmacist says: ‘Why are you on an antipsychotic?’ ”
Further results from the survey revealed that 56 (71%) respondents did not have access to a specialist psychodermatology clinic, whereas 36 (46%) had not yet attended a psychodermatology course.
Despite these responses, 60 (77%) respondents said they would be interested in attending a training course for prescribing antipsychotics, which included all 20 of the registrars who took part in the survey. a psychodermatologist at Frimley Health Foundation Trust, Windsor, England, and lead author of the BAD guidelines, commented from the audience that the survey results were “sort of what we expected.”
She explained that the intention of the authors when developing the guidelines “was to be able to help our junior colleagues and our peers to be able to feel competent to discuss antipsychotics with patients with delusional infestation and also initiate management.”
Dr. Ahmed added: “Why we’re encouraging our colleagues to prescribe antipsychotics is the longer you leave this type of psychotic illness untreated, the worse the prognosis.”

GLASGOW – that also indicated there is a clear demand for training in prescribing these drugs.
Delusional infestation is a rare disorder characterized by an individual’s belief that his or her skin, body, or immediate environment is infested by small, living pathogens, despite a lack of any medical evidence. Most of these patients require antipsychotic medication to alleviate symptoms.
The survey of almost 80 dermatologists found that almost 90% had not prescribed antipsychotics in the previous month for patients with psychodermatology conditions and that the most common barrier to prescribing was lack of experience with the drugs.
This was reflected in only 10% of survey respondents who said they were “happy to” prescribe antipsychotics without consulting either dermatology or psychiatric colleagues, and less than half having attended a related course.
Yet the research, presented at the annual meeting of the British Association of Dermatologists, indicated that more than 75% of respondents would attend such a course to increase their confidence.
This finding, said study presenter Ling Li, MD, Churchill Hospital, Oxford (England) University Hospitals NHS Foundation Trust, shows that there is a “clear demand for training, particularly among all the registrars [residents] who we surveyed.”
Dr. Li noted that the UK’s Joint Royal Colleges of Physicians Training Board’s latest curriculum for dermatology training highlights psychocutaneous medicine as a key area, and “that will include antipsychotic medication.”
The BAD also recently published guidelines for the management of adults with delusional infestation, which includes a recommendation to conduct a survey on attitudes toward antipsychotic prescribing for the condition among U.K. dermatologists.
Heeding that call, Dr. Li and colleagues sent an email containing a 10-question online survey to members of the BAD and the British Society for Medical Dermatology. Questions covered familiarity with antipsychotics and frequency of prescribing, confidence around antipsychotics, and current training and future needs. Responses were received between February through April 2021.
Among the 79 respondents, 51 (65%) were consultants and 20 (25%) were dermatology registrars, with the remainder dermatology clinical fellows, foundation doctors, or other doctors. A total of 31 respondents had an average of more than 50 visits with patients per week, 18 had an average of 41-50 patient visits, and 13 had an average of 31-40 visits per week; the remainder had an average of 11-30 visits per week.
Most of the respondents (39) said they had seen 2-5 patients with psychodermatology conditions in the last 6 months, while 17 said they had seen 1 patient, 13 said they had seen more than 10 patients, and 6 said they had seen 6-10 patients (4 had seen none and 1 could not remember).
The most commonly prescribed antipsychotics for psychodermatology patients in the past 6 months were risperidone (Risperdal; prescribed by five respondents), followed by olanzapine (Zyprexa; by four respondents). Seventy respondents had not prescribed any antipsychotics.
Asked about how confident they felt about prescribing antipsychotic medication for patients with delusional infestation, 8 (10%) said they were happy to prescribe independently, while 42 (54%) said they were not at all confident. Another 10 (13%) respondents said they would be happy to prescribe the medications after liaising with a dermatology colleague, while 17 (22%) said they would prefer to consult with the psychiatry team.
The most common barrier to prescribing antipsychotic medications was a lack of experience with the drugs, cited by 66 respondents, followed by concerns over drug monitoring, cited by 43 respondents.
In addition, 42 respondents highlighted concerns over adverse effects, 36 cited lack of experience in psychodermatology clinics, and 19 cited lack of experience in discussing psychodermatologic conditions with patients. Other barriers mentioned by the respondents included difficulties with patient acceptance of a psychiatric medication prescribed by a dermatologist.

Quality of life benefit exaggerated in some cancer studies
, according to a study published in JAMA Oncology.
The study found trials that failed to show improved quality of life often reported their quality of life outcomes more favorably. Non–immunotherapy-targeted drugs were found to lead to worse quality of life outcomes more often than did cytotoxic agents. And, while there is an association between quality of life benefit and overall survival, no such association was found with progression-free survival.
“In this study, we evaluated the outcomes of cancer drug trials with regard to patients’ quality of life and found that only a quarter of phase 3 cancer drug trials in the advanced-disease setting demonstrated improved quality of life,” wrote authors who were led by Bishal Gyawali, MD, PhD, of the Cancer Research Institute, Queen’s University, Kingston, Ont.
“Improved quality of life outcomes were associated with improved overall survival but not with improved progression-free survival. Importantly, almost half of the cancer drugs drug trials that showed improved progression-free survival showed no improved overall survival or quality of life (i.e., PFS-only benefit). Some reports included conclusions regarding quality of life (QOL) findings that were not directly supported by the trial data, particularly for inferior or non–statistically significant QOL outcomes, thereby framing the findings in a favorable light or downplaying detrimental effects of the study intervention on QOL. Furthermore, contrary to common perception, inferior QOL outcomes were more common with targeted drugs than cytotoxic drugs. Taken together, these findings have important policy implications,” the authors wrote.
These findings are based on the results of a cohort study of 45 phase 3 research clinical trials of 24,806 patients. Only a small percentage of patients showed QOL benefits. The study found that industry-funded clinical trial reports often framed QOL findings more favorably than was warranted by the data.
The study found improved QOL with experimental agents in 11 of 45 randomized controlled trials (24.4%). Studies that reported improved QOL were more likely to also show improved overall survival as compared with trials in which quality of life was not improved (7 of 11 [64%] versus 10 of 34 [29%] trials). For improved progression-free survival, however, there was no positive association (6 of 11 [55%] trials versus 17 of 34 [50%] trials without improved QOL). Among six trials reporting worsening QOL, three (50%) were trials of targeted drugs. Among 11 trials reporting improved QOL, 6 (55%) were trials of immunotherapy drugs. Among the 34 trials in which QOL was not improved compared with controls, the findings were framed favorably (versus neutrally or negatively) in the abstract or conclusions in 16 (47%), an observation that was statistically significantly associated with industry funding (chi-squared = 6.35; P = .01).
“It is important to clearly understand and communicate the effects of cancer drugs”
To fulfill the obligation to inform patients about proposed treatments, the authors wrote that it is important to clearly understand and communicate the effects of cancer drugs on patient quality of life alongside their effects on overall survival and intermediate end points such as progression-free survival. “Patients with advanced cancer expect treatment to help them live longer or have better lives,” the authors wrote. In that respect, in clinical trials of cancer medicines, overall survival and quality of life are the most important measures. Toxicity profiles and disease progression delays do not reliably predict quality of life, and studies have shown poor correlations between quality of life, overall survival, and progression-free survival. This raises the question of validity of progression-free survival as a surrogate endpoint. “Progression-free survival is meaningless without overall survival or quality of life gains,” Dr. Gyawali said in an interview.
Writing in The Lancet Oncology in March, Dr. Gyawali stated that, because progression free survival “does not directly measure how a patient feels or functions, or how long a patient lives, progression-free survival was not intended to inform clinical practice or establish whether a new therapy provides clinically meaningful benefits for patients. However, over the past 2 decades, it has become the most common primary endpoint in oncology clinical trials. We are deeply worried about how the term survival in this phrase can influence clinical practice and patient choices. We propose replacing the phrase progression-free survival with a less ambiguous term: progression-free interval.”
In JAMA Oncology, Dr. Gyawali aimed to elucidate relationships between QOL, overall survival, and progression-free survival, and to assess, as well, how QOL results are framed, especially in industry-sponsored research. When drug trials they analyzed showed no change in QOL but reported that QOL did not worsen or QOL was maintained rather than stating that QOL did not improve, or if there was downplaying of worse QOL outcomes, the study had favorable interpretation, Dr. Gyawali and associates wrote. The expectation of patients receiving cancer drugs would be improved QOL rather than “not worse” QOL, Dr. Gyawali said.
Regarding the finding that QOL outcomes were described as favorable in 47% of trials with unimproved QOL outcomes, Dr. Gyawali said, “the bias in reporting should be corrected by the reviewers and editors of journals. Also, quality of life reporting should be made mandatory. Without unbiased quality of life information, informed decision making on whether or not to use a certain drug is impossible. Patients and physicians need to know that information. Regulators can demand that this should be mandatory in all trials in noncurative settings.”
He remarked further on the worsening QOL in some targeted drug trials, “People tout chemo-free regimens as automatically having better quality of life, but that doesn’t seem to be the case. Targeted drugs can have a severe impact on quality of life, probably due to prolonged duration of side effects. Quality of life should be measured and reported for all drugs.”
Dr. Gyawali and associates noted the limitation in that several studies with negative QOL results are not published at all or are published after a considerable delay, so the present observations may understate the issues that have been raised.
Dr. Gyawali declared that he received no funding and disclosed no conflicts of interest for this study.
