Updated celiac disease guideline addresses common clinical questions
The American College of Gastroenterology issued updated guidelines for celiac disease diagnosis, management, and screening that incorporates research conducted since the last update in 2013.
The guidelines offer evidence-based recommendations for common clinical questions on topics that include nonbiopsy diagnosis, gluten-free oats, probiotic use, and gluten-detection devices. They also point to areas for ongoing research.
“The main message of the guideline is all about quality of care,” Alberto Rubio-Tapia, MD, a gastroenterologist at the Cleveland Clinic, said in an interview.
“A precise celiac disease diagnosis is just the beginning of the role of the gastroenterologist,” he said. “But most importantly, we need to take care of our patients’ needs with good goal-directed follow-up using a multidisciplinary approach, with experienced dietitians playing an important role.”
The update was published in the American Journal of Gastroenterology.
Diagnosis recommendations
The ACG assembled a team of celiac disease experts and expert guideline methodologists to develop an update with high-quality evidence, Dr. Rubio-Tapia said. The authors made recommendations and suggestions for future research regarding eight questions concerning diagnosis, disease management, and screening.
For diagnosis, the guidelines recommend esophagogastroduodenoscopy (EGD) with multiple duodenal biopsies – one or two from the bulb and four from the distal duodenum – for confirmation in children and adults with suspicion of celiac disease. EGD and duodenal biopsies can also be useful for the differential diagnosis of other malabsorptive disorders or enteropathies, the authors wrote.
For children, a nonbiopsy option may be considered to be reliable for diagnosis. This option includes a combination of high-level tissue transglutaminase (TTG) IgA – at greater than 10 times the upper limit of normal – and a positive endomysial antibody finding in a second blood sample. The same criteria may be considered after the fact for symptomatic adults who are unwilling or unable to undergo upper GI endoscopy.
For children younger than 2 years, the TTG-IgA is the preferred test for those who are not IgA deficient. For children with IgA deficiency, testing should be performed using IgG-based antibodies.
Disease management guidance
After diagnosis, intestinal healing should be the endpoint for a gluten-free diet, the guidelines recommended. Clinicians and patients should discuss individualized goals of the gluten-free diet beyond clinical and serologic remission.
The standard of care for assessing patients’ diet adherence is an interview with a dietician who has expertise in gluten-free diets, the recommendations stated. Subsequent visits should be encouraged as needed to reinforce adherence.
During disease management, upper endoscopy with intestinal biopsies can be helpful for monitoring cases in which there is a lack of clinical response or in which symptoms relapse despite a gluten-free diet, the authors noted.
In addition, after a shared decision-making conversation between the patient and provider, a follow-up biopsy could be considered for assessment of mucosal healing in adults who don’t have symptoms 2 years after starting a gluten-free diet, they wrote.
“Although most patients do well on a gluten-free diet, it’s a heavy burden of care and an important issue that impacts patients,” Joseph Murray, MD, a gastroenterologist at the Mayo Clinic in Rochester, Minn., said in an interview.
Dr. Murray, who wasn’t involved with this guideline update, contributed to the 2013 guidelines and the 2019 American Gastroenterological Association practice update on diagnosing and monitoring celiac disease. He agreed with many of the recommendations in this update.
“The goal of achieving healing is a good goal to reach. We do that routinely in my practice,” he said. “The older the patient, perhaps the more important it is to discuss, including the risk for complications. There’s a nuance involved with shared decision-making.”
Nutrition advice
The guidelines recommended against routine use of gluten-detection devices for food or biospecimens for patients with celiac disease. Although multiple devices have become commercially available in recent years, they are not regulated by the Food and Drug Administration and have sensitivity problems that can lead to false positive and false negative results, the authors noted. There’s also a lack of evidence that the devices enhance diet adherence or quality of life.
The evidence is insufficient to recommend for or against the use of probiotics for the treatment of celiac disease, the recommendations stated. Although dysbiosis is a feature of celiac disease, its role in disease pathogenesis and symptomatology is uncertain, the authors wrote.
Probiotics may help with functional disorders, such as irritable bowel syndrome, but because probiotics are marketed as supplements and regulations are lax, some products may contain detectable gluten despite being labeled gluten free, they added.
On the other hand, the authors recommended gluten-free oats as part of a gluten-free diet. Oat consumption appears to be safe for most patients with celiac disease, but it may be immunogenic in a subset of patients, depending on the products or quantity consumed. Given the small risk for an immune reaction to the oat protein avenin, monitoring for oat tolerance through symptoms and serology should be conducted, although the intervals for monitoring remain unknown.
Vaccination and screening
The guidelines also support vaccination against pneumococcal disease, since adults with celiac disease are at significantly increased risk of infection and complications. Vaccination is widely recommended for people aged 65 and older, for smokers aged 19-64, and for adults with underlying conditions that place them at higher risk, the authors noted.
Overall, the guidelines recommended case findings to increase detection of celiac disease in clinical practice but recommend against mass screening in the community. Patients with symptoms for whom there is lab evidence of malabsorption should be tested, as well as those for whom celiac disease could be a treatable cause of symptoms, the authors wrote. Those with a first-degree family member who has a confirmed diagnosis should also be tested if they have possible symptoms, and asymptomatic relatives should consider testing as well.
The updated guidelines include changes that are important for patients and patient care, and they emphasize the need for continued research on key questions, Isabel Hujoel, MD, a gastroenterologist at the University of Washington Medical Center, Seattle, told this news organization.
“In particular, the discussion on the lack of evidence behind gluten-detection devices and probiotic use in celiac disease addresses conversations that come up frequently in clinic,” said Dr. Hujoel, who wasn’t involved with the update. “The guidelines also include a new addition below each recommendation where future research questions are raised. Many of these questions address gaps in our understanding on celiac disease, such as the possibility of a nonbiopsy diagnosis in adults, which will potentially dramatically impact patient care if addressed.”
The update received no funding. The authors, Dr. Murray, and Dr. Hujoel have disclosed no relevant financial relationships.

AD outcomes improved with lebrikizumab and topical steroids
, according to results of the 16-week phase 3 ADhere trial.
“Lebrikizumab, a monoclonal antibody inhibiting interleukin-13, combined with TCS was associated with reduced overall disease severity of moderate to severe AD in adolescents and adults, and had a safety profile consistent with previous lebrikizumab AD studies,” noted lead author Eric L. Simpson, MD, professor of dermatology at Oregon Health & Science University, Portland, and coauthors in their article on the study, which was published in JAMA Dermatology.
The double-blind trial, conducted at 54 sites across Germany, Poland, Canada, and the United States, included 211 patients, mean age 37.2 years, of whom 48.8% were female and roughly 22% were adolescents. Almost 15% were Asian, and about 13% were Black.
At baseline, participants had a score of 16 or higher on the Eczema Area and Severity Index (EASI), a score of 3 or higher on the Investigator’s Global Assessment (IGA) scale, AD covering a body surface area of 10% or greater, and a history of inadequate response to treatment with topical medications.
After a minimum 1-week washout period from topical and systemic therapy, participants were randomized in a 2:1 ratio to receive lebrikizumab plus TCS (n = 145) or placebo plus TCS (n = 66) for 16 weeks.
Lebrikizumab or placebo was administered by subcutaneous injection every 2 weeks; the loading and week-2 doses of lebrikizumab were 500 mg, followed by 250 mg thereafter. All patients were instructed to use low- to mid-potency TCS at their own discretion. Study sites provided a mid-potency TCS (triamcinolone acetonide 0.1% cream) and a low-potency TCS (hydrocortisone 1% cream), with topical calcineurin inhibitors permitted for sensitive skin areas.
Primary outcomes at 16 weeks included a 2-point or more reduction in IGA score from baseline and EASI-75 response. Patients in the lebrikizumab arm had superior responses on both of these outcomes, with statistical significance achieved as early as week 8 and week 4, respectively, and maintained through week 16. Specifically, 41.2% of those treated with lebrikizumab had an IGA reduction of 2 points or more, compared with 22.1% of those receiving placebo plus TCS (P = .01), and the proportion of patients achieving EASI-75 responses was 69.5% vs. 42.2%, respectively (P < .001).
Patients treated with lebrikizumab also showed statistically significant improvements, compared with TCS alone in all key secondary endpoints, “including skin clearance, improvement in itch, itch interference on sleep, and enhanced QoL [quality of life],” noted the authors. “This study captured the clinical benefit of lebrikizumab through the combined end point of physician-assessed clinical sign of skin clearance (EASI-75) and patient-reported outcome of improvement in itch (Pruritus NRS).”
The percentage of patients who achieved the combined endpoint was more than double for the lebrikizumab plus TCS group vs. the group on TCS alone, indicating that patients treated with lebrikizumab plus TCS “were more likely to experience improvement in skin symptoms and itch,” the investigators added.
The authors noted that most treatment-emergent adverse events “were nonserious, mild, or moderate in severity, and did not lead to study discontinuation.” These included conjunctivitis (4.8%), headache (4.8%), hypertension (2.8%), injection-site reactions (2.8%), and herpes infection (3.4%) – all of which occurred in 1.5% or less of patients in the placebo group.
“The higher incidence of conjunctivitis has also been reported in other biologics inhibiting IL [interleukin]–13 and/or IL-4 signaling, as well as lebrikizumab monotherapy studies,” they noted. The 4.8% rate of conjunctivitis reported in the combination study, they added, is “compared with 7.5% frequency in 16-week data from the lebrikizumab monotherapy studies. Although the mechanism remains unclear, it has been reported that conjunctival goblet cell scarcity due to IL-13 and IL-4 inhibition, and subsequent effects on the homeostasis of the conjunctival mucosal surface, results in ocular AEs [adverse events].”
“This truly is a time of great hope and promise for our patients with AD,” commented Zelma Chiesa Fuxench, MD, who was not involved in the study. “The advent of newer, targeted therapeutic agents for AD continues to revolutionize the treatment experience for our patients, offering the possibility of greater AD disease control with a favorable risk profile and less need for blood work monitoring compared to traditional systemic agents.”
On the basis of the study results, Dr. Chiesa Fuxench, of the department of dermatology at the University of Pennsylvania, Philadelphia, said in an interview that “lebrikizumab represents an additional option in the treatment armamentarium for providers who care for patients with AD.” She added that, “while head-to-head trials comparing lebrikizumab to dupilumab, the first FDA-approved biologic for AD, would be beneficial, to the best of my knowledge this data is currently lacking. However, based on the results of this study, we would expect lebrikizumab to work at least similarly to dupilumab, based on the reported improvements in IGA and EASI score.”
Additionally, lebrikizumab showed a favorable safety profile, “with most treatment-emergent adverse effects reported as nonserious and not leading to drug discontinuation,” she said. “Of interest to clinicians may be the reported rates of conjunctivitis in this study. Rates of conjunctivitis for lebrikizumab appear to be lower than those reported in the LIBERTY AD CHRONOS study for dupilumab – a finding that merits further scrutiny in my opinion, as this one of the most frequent treatment-emergent adverse events that I encounter in my clinical practice.”
The study was funded by Dermira, a subsidiary of Eli Lilly. Dr. Simpson reported personal fees and grants from multiple sources, including Dermira and Eli Lilly, the companies developing lebrikizumab. Several authors were employees of Eli Lilly. Dr. Fuxench disclosed serving as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, Pfizer, AbbVie, and Incyte, for which she has received honoraria for AD-related work. She is the recipient of research grants through Regeneron, Sanofi, Tioga, Vanda, Menlo Therapeutics, Leo Pharma, and Eli Lilly for work related to AD as well as honoraria for continuing medical education work related to AD sponsored through educational grants from Regeneron/Sanofi and Pfizer.

At baseline, participants had a score of 16 or higher on the Eczema Area and Severity Index (EASI), a score of 3 or higher on the Investigator’s Global Assessment (IGA) scale, AD covering a body surface area of 10% or greater, and a history of inadequate response to treatment with topical medications.
After a minimum 1-week washout period from topical and systemic therapy, participants were randomized in a 2:1 ratio to receive lebrikizumab plus TCS (n = 145) or placebo plus TCS (n = 66) for 16 weeks.
Lebrikizumab or placebo was administered by subcutaneous injection every 2 weeks; the loading and week-2 doses of lebrikizumab were 500 mg, followed by 250 mg thereafter. All patients were instructed to use low- to mid-potency TCS at their own discretion. Study sites provided a mid-potency TCS (triamcinolone acetonide 0.1% cream) and a low-potency TCS (hydrocortisone 1% cream), with topical calcineurin inhibitors permitted for sensitive skin areas.
Primary outcomes at 16 weeks included a 2-point or more reduction in IGA score from baseline and EASI-75 response. Patients in the lebrikizumab arm had superior responses on both of these outcomes, with statistical significance achieved as early as week 8 and week 4, respectively, and maintained through week 16. Specifically, 41.2% of those treated with lebrikizumab had an IGA reduction of 2 points or more, compared with 22.1% of those receiving placebo plus TCS (P = .01), and the proportion of patients achieving EASI-75 responses was 69.5% vs. 42.2%, respectively (P < .001).
Patients treated with lebrikizumab also showed statistically significant improvements, compared with TCS alone in all key secondary endpoints, “including skin clearance, improvement in itch, itch interference on sleep, and enhanced QoL [quality of life],” noted the authors. “This study captured the clinical benefit of lebrikizumab through the combined end point of physician-assessed clinical sign of skin clearance (EASI-75) and patient-reported outcome of improvement in itch (Pruritus NRS).”
The percentage of patients who achieved the combined endpoint was more than double for the lebrikizumab plus TCS group vs. the group on TCS alone, indicating that patients treated with lebrikizumab plus TCS “were more likely to experience improvement in skin symptoms and itch,” the investigators added.
The authors noted that most treatment-emergent adverse events “were nonserious, mild, or moderate in severity, and did not lead to study discontinuation.” These included conjunctivitis (4.8%), headache (4.8%), hypertension (2.8%), injection-site reactions (2.8%), and herpes infection (3.4%) – all of which occurred in 1.5% or less of patients in the placebo group.
“The higher incidence of conjunctivitis has also been reported in other biologics inhibiting IL [interleukin]–13 and/or IL-4 signaling, as well as lebrikizumab monotherapy studies,” they noted. The 4.8% rate of conjunctivitis reported in the combination study, they added, is “compared with 7.5% frequency in 16-week data from the lebrikizumab monotherapy studies. Although the mechanism remains unclear, it has been reported that conjunctival goblet cell scarcity due to IL-13 and IL-4 inhibition, and subsequent effects on the homeostasis of the conjunctival mucosal surface, results in ocular AEs [adverse events].”
“This truly is a time of great hope and promise for our patients with AD,” commented Zelma Chiesa Fuxench, MD, who was not involved in the study. “The advent of newer, targeted therapeutic agents for AD continues to revolutionize the treatment experience for our patients, offering the possibility of greater AD disease control with a favorable risk profile and less need for blood work monitoring compared to traditional systemic agents.”
On the basis of the study results, Dr. Chiesa Fuxench, of the department of dermatology at the University of Pennsylvania, Philadelphia, said in an interview that “lebrikizumab represents an additional option in the treatment armamentarium for providers who care for patients with AD.” She added that, “while head-to-head trials comparing lebrikizumab to dupilumab, the first FDA-approved biologic for AD, would be beneficial, to the best of my knowledge this data is currently lacking. However, based on the results of this study, we would expect lebrikizumab to work at least similarly to dupilumab, based on the reported improvements in IGA and EASI score.”
Additionally, lebrikizumab showed a favorable safety profile, “with most treatment-emergent adverse effects reported as nonserious and not leading to drug discontinuation,” she said. “Of interest to clinicians may be the reported rates of conjunctivitis in this study. Rates of conjunctivitis for lebrikizumab appear to be lower than those reported in the LIBERTY AD CHRONOS study for dupilumab – a finding that merits further scrutiny in my opinion, as this one of the most frequent treatment-emergent adverse events that I encounter in my clinical practice.”
The study was funded by Dermira, a subsidiary of Eli Lilly. Dr. Simpson reported personal fees and grants from multiple sources, including Dermira and Eli Lilly, the companies developing lebrikizumab. Several authors were employees of Eli Lilly. Dr. Fuxench disclosed serving as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, Pfizer, AbbVie, and Incyte, for which she has received honoraria for AD-related work. She is the recipient of research grants through Regeneron, Sanofi, Tioga, Vanda, Menlo Therapeutics, Leo Pharma, and Eli Lilly for work related to AD as well as honoraria for continuing medical education work related to AD sponsored through educational grants from Regeneron/Sanofi and Pfizer.

Children and COVID: ED visits and hospitalizations start to fall again
Emergency department visits and hospitalizations for COVID-19 in children appear to be following the declining trend set by weekly cases since early December, based on data from the Centers for Disease Control and Prevention.
. New cases took a different path that had the weekly total falling through November before taking a big jump during the week of Nov. 27 to Dec. 3 – the count doubled from 30,000 the previous week to 63,000 – and then decreased again,The proportion of ED visits with COVID, which was down to 1.0% of all ED visits (7-day average) for children aged 0-4 years on Nov. 4, was up to 3.2% on Jan. 3 but slipped to 2.5% as of Jan. 10. The patterns for older children are similar, with some differences in timing and lower peaks (1.7% for 12- to 15-year-olds and 1.9% for those aged 16-17), according to the CDC’s COVID Data Tracker.
The trend for new hospital admissions of children with confirmed COVID showed a similar rise through December, and the latest data for the very beginning of January suggest an even faster drop, although there is more of a reporting lag with hospitalization data, compared with ED visits, the CDC noted.
The most current data (Dec. 30 to Jan. 5) available from the American Academy of Pediatrics and the Children’s Hospital Association show less volatility in the number of weekly cases through November and December, with the peak being about 48,000 in mid-December. The AAP/CHA totals for the last 2 weeks, however, were both higher than the CDC’s corresponding counts, which are more preliminary and subject to revision.
The CDC puts the total number of COVID cases in children at 16.7 million – about 17.2% of all cases – as of Jan. 11, with 1,981 deaths reported so far. The AAP and CHA are not tracking deaths, but their case total as of Jan. 5 was 15.2 million, which represents 18.1% of cases in all ages. The AAP/CHA report is based on data reported publicly by an ever-decreasing number of states and territories.

Manicure gone wrong leads to cancer diagnosis
. Now, she and her doctor are spreading the word about her ordeal as a lesson that speed and persistence in seeking treatment are the keys that make her type of cancer – squamous cell carcinoma – completely curable.
“She cut me, and the cut wasn’t just a regular cuticle cut. She cut me deep, and that was one of the first times that happened to me,” Grace Garcia, 50, told TODAY.com, recalling the November 2021 incident.
Ms. Garcia had been getting her nails done regularly for 20 years, she said, but happened to go to a different salon than her usual spot because she couldn’t get an appointment during the busy pre-Thanksgiving season. She doesn’t recall whether the technician opened packaging that signals unused tools.
She put antibiotic ointment on the cut, but it didn’t heal after a few days. Eventually, the skin closed and a darkened bump formed. It was painful. She went to her doctor, who said it was a “callus from writing,” she told TODAY.com. But it was on her ring finger, which didn’t seem connected to writing. Her doctor said to keep an eye on it.
Five months after the cut occurred, she mentioned it during a gynecology appointment and was referred to a dermatologist, who also advised keeping an eye on it. A wart developed. She went back to her primary care physician and then to another dermatologist. The spot was biopsied.
Squamous cell carcinoma is a common type of skin cancer, according to the American Academy of Dermatology. It can have many causes, but the cause in Ms. Garcia’s case was both very common and very rare: human papillomavirus, or HPV. HPV is a virus that infects millions of people every year, but it’s not a typical cause of skin cancer.
“It’s pretty rare for several reasons. Generally speaking, the strains that cause cancer from an HPV standpoint tend to be more sexually transmitted,” dermatologist Teo Soleymani told TODAY.com. “In Grace’s case, she had an injury, which became the portal of entry. So that thick skin that we have on our hands and feet that acts as a natural barrier against infections and things like that was no longer the case, and the virus was able to infect her skin.”
Dr. Soleymani said Ms. Garcia’s persistence to get answers likely saved her from losing a finger.
“Your outcomes are entirely dictated by how early you catch them, and very often they’re completely curable,” he said. “Her persistence – not only was she able to have a great outcome, she probably saved herself from having her finger amputated.”

Scaly facial plaques
This patient was experiencing a flare of his psoriasis. Three factors contributed to the flare: noncompliance with his treatment regimen, decreased sunlight in the winter, and his lithium therapy. Though carcinogenic, certain wavelengths of UV light are beneficial for psoriasis, and the shorter days of winter can cause flaring of psoriasis (or relative flaring). In addition, lithium—the most effective therapy for this patient’s bipolar disorder—can worsen psoriasis.
Psoriasis is a chronic multisystem inflammatory disorder with characteristic skin findings that include well-demarcated micaceous plaques, nail pitting, and sometimes tendon pain and inflammatory arthritis. Severity can range from small, thin plaques that are intermittently noticeable on the elbows or knees to widespread ash-like plaques covering most of the body.
Good topical choices for facial skin include hydrocortisone 2.5% cream or desonide 0.05%. Nonsteroidal topical therapies that are safe for facial skin include tacrolimus 0.1% ointment or pimecrolimus 1% cream.1 These options may be used twice daily until the disease is controlled.
In many cases (as in this one), the patient’s previous psoriasis outbreaks could not be controlled with topical therapy alone. The patient had not responded to a previous methotrexate regimen, and more recently had been clear for several years on systemic ustekinumab, a monoclonal antibody. Dosed every 12 weeks, or sometimes every 8 weeks, ustekinumab is given by subcutaneous injection, usually in the abdomen, through normal skin. Ustekinumab was recently approved for home use with just 4 injections per year for maintenance therapy. However, the infrequency of the injections sometimes leads to noncompliance, as occurred with this patient. He had missed 2 doses since taking over his own dosing regimen.
Ultimately, the patient’s flare resolved when he was transitioned back to in-office treatment with ustekinumab.

Add this to the list of long COVID symptoms: Stigma
Most people with long COVID find they’re facing stigma due to their condition, according to a new report from researchers in the United Kingdom. In short: Relatives and friends may not believe they’re truly sick.
The U.K. team found that more than three-quarters of people studied had experienced stigma often or always.
In fact, 95% of people with long COVID faced at least one type of stigma at least sometimes, according to the study, published in November in the journal PLOS One.
Those conclusions had surprised the study’s lead researcher, Marija Pantelic, PhD, a public health lecturer at Brighton and Sussex Medical School, England.
“After years of working on HIV-related stigma, I was shocked to see how many people were turning a blind eye to and dismissing the difficulties experienced by people with long COVID,” Dr. Pantelic says. “It has also been clear to me from the start that this stigma is detrimental not just for people’s dignity, but also public health.”
Even some doctors argue that the growing attention paid to long COVID is excessive.
“It’s often normal to experience mild fatigue or weaknesses for weeks after being sick and inactive and not eating well. Calling these cases long COVID is the medicalization of modern life,” Marty Makary, MD, a surgeon and public policy researcher at Johns Hopkins University, Baltimore, wrote in a commentary in the Wall Street Journal.
Other doctors strongly disagree, including Alba Azola, MD, codirector of the Johns Hopkins Post-Acute COVID-19 Team and an expert in the stigma surrounding long COVID.
“Putting that spin on things, it’s just hurting people,” she says.
One example is people who cannot return to work.
“A lot of their family members tell me that they’re being lazy,” Dr. Azola says. “That’s part of the public stigma, that these are people just trying to get out of work.”
Some experts say the U.K. study represents a landmark.
“When you have data like this on long COVID stigma, it becomes more difficult to deny its existence or address it,” says Naomi Torres-Mackie, PhD, a clinical psychologist at Lenox Hill Hospital in New York. She also is head of research at the New York–based Mental Health Coalition, a group of experts working to end the stigma surrounding mental health.
She recalls her first patient with long COVID.
“She experienced the discomfort and pain itself, and then she had this crushing feeling that it wasn’t valid, or real. She felt very alone in it,” Dr. Torres-Mackie says.
Another one of her patients is working at her job from home but facing doubt about her condition from her employers.
“Every month, her medical doctor has to produce a letter confirming her medical condition,” Dr. Torres-Mackie says.
Taking part in the British stigma survey were 1,166 people, including 966 residents of the United Kingdom, with the average age of 48. Nearly 85% were female, and more than three-quarters were educated at the university level or higher.
Half of them said they had a clinical diagnosis of long COVID.
More than 60% of them said that at least some of the time, they were cautious about who they talked to about their condition. And fully 34% of those who did disclose their diagnosis said that they regretted having done so.
That’s a difficult experience for those with long COVID, says Leonard Jason, PhD, a professor of psychology at DePaul University in Chicago.
“It’s like they’re traumatized by the initial experience of being sick, and retraumatized by the response of others to them,” he says.
Unexplained illnesses are not well-regarded by the general public, Dr. Jason says.
He gave the example of multiple sclerosis. Before the 1980s, those with MS were considered to have a psychological illness, he says. “Then, in the 1980s, there were biomarkers that said, ‘Here’s the evidence.’ ”
The British study described three types of stigma stemming from the long COVID diagnosis of those questioned:
- Enacted stigma: People were directly treated unfairly because of their condition.
- Internalized stigma: People felt embarrassed by that condition.
- Anticipated stigma: People expected they would be treated poorly because of their diagnosis.
Dr. Azola calls the medical community a major problem when it comes to dealing with long COVID.
“What I see with my patients is medical trauma,” she says. They may have symptoms that send them to the emergency room, and then the tests come back negative. “Instead of tracking the patients’ symptoms, patients get told, ‘Everything looks good, you can go home, this is a panic attack,’ ” she says.
Some people go online to search for treatments, sometimes launching GoFundMe campaigns to raise money for unreliable treatments.
Long COVID patients may have gone through 5 to 10 doctors before they arrive for treatment with the Johns Hopkins Post-Acute COVID-19 Team. The clinic began in April 2020 remotely and in August of that year in person.
Today, the clinic staff spends an hour with a first-time long COVID patient, hearing their stories and helping relieve anxiety, Dr. Azola says.
The phenomenon of long COVID is similar to what patients have had with chronic fatigue syndrome, lupus, or fibromyalgia, where people have symptoms that are hard to explain, says Jennifer Chevinsky, MD, deputy public health officer for Riverside County, Calif.
“Stigma within medicine or health care is nothing new,” she says.
In Chicago, Dr. Jason notes that the federal government’s decision to invest hundreds of millions of dollars in long COVID research “shows the government is helping destigmatize it.”
Dr. Pantelic says she and her colleagues are continuing their research.
“We are interested in understanding the impacts of this stigma, and how to mitigate any adverse outcomes for patients and services,” she says.

“When you have data like this on long COVID stigma, it becomes more difficult to deny its existence or address it,” says Naomi Torres-Mackie, PhD, a clinical psychologist at Lenox Hill Hospital in New York. She also is head of research at the New York–based Mental Health Coalition, a group of experts working to end the stigma surrounding mental health.
She recalls her first patient with long COVID.
“She experienced the discomfort and pain itself, and then she had this crushing feeling that it wasn’t valid, or real. She felt very alone in it,” Dr. Torres-Mackie says.
Another one of her patients is working at her job from home but facing doubt about her condition from her employers.
“Every month, her medical doctor has to produce a letter confirming her medical condition,” Dr. Torres-Mackie says.
Taking part in the British stigma survey were 1,166 people, including 966 residents of the United Kingdom, with the average age of 48. Nearly 85% were female, and more than three-quarters were educated at the university level or higher.
Half of them said they had a clinical diagnosis of long COVID.
More than 60% of them said that at least some of the time, they were cautious about who they talked to about their condition. And fully 34% of those who did disclose their diagnosis said that they regretted having done so.
That’s a difficult experience for those with long COVID, says Leonard Jason, PhD, a professor of psychology at DePaul University in Chicago.
“It’s like they’re traumatized by the initial experience of being sick, and retraumatized by the response of others to them,” he says.
Unexplained illnesses are not well-regarded by the general public, Dr. Jason says.
He gave the example of multiple sclerosis. Before the 1980s, those with MS were considered to have a psychological illness, he says. “Then, in the 1980s, there were biomarkers that said, ‘Here’s the evidence.’ ”
The British study described three types of stigma stemming from the long COVID diagnosis of those questioned:
- Enacted stigma: People were directly treated unfairly because of their condition.
- Internalized stigma: People felt embarrassed by that condition.
- Anticipated stigma: People expected they would be treated poorly because of their diagnosis.
Dr. Azola calls the medical community a major problem when it comes to dealing with long COVID.
“What I see with my patients is medical trauma,” she says. They may have symptoms that send them to the emergency room, and then the tests come back negative. “Instead of tracking the patients’ symptoms, patients get told, ‘Everything looks good, you can go home, this is a panic attack,’ ” she says.
Some people go online to search for treatments, sometimes launching GoFundMe campaigns to raise money for unreliable treatments.
Long COVID patients may have gone through 5 to 10 doctors before they arrive for treatment with the Johns Hopkins Post-Acute COVID-19 Team. The clinic began in April 2020 remotely and in August of that year in person.
Today, the clinic staff spends an hour with a first-time long COVID patient, hearing their stories and helping relieve anxiety, Dr. Azola says.
The phenomenon of long COVID is similar to what patients have had with chronic fatigue syndrome, lupus, or fibromyalgia, where people have symptoms that are hard to explain, says Jennifer Chevinsky, MD, deputy public health officer for Riverside County, Calif.
“Stigma within medicine or health care is nothing new,” she says.
In Chicago, Dr. Jason notes that the federal government’s decision to invest hundreds of millions of dollars in long COVID research “shows the government is helping destigmatize it.”
Dr. Pantelic says she and her colleagues are continuing their research.
“We are interested in understanding the impacts of this stigma, and how to mitigate any adverse outcomes for patients and services,” she says.

Most people with long COVID find they’re facing stigma due to their condition, according to a new report from researchers in the United Kingdom. In short: Relatives and friends may not believe they’re truly sick.
The U.K. team found that more than three-quarters of people studied had experienced stigma often or always.
In fact, 95% of people with long COVID faced at least one type of stigma at least sometimes, according to the study, published in November in the journal PLOS One.
Those conclusions had surprised the study’s lead researcher, Marija Pantelic, PhD, a public health lecturer at Brighton and Sussex Medical School, England.
“After years of working on HIV-related stigma, I was shocked to see how many people were turning a blind eye to and dismissing the difficulties experienced by people with long COVID,” Dr. Pantelic says. “It has also been clear to me from the start that this stigma is detrimental not just for people’s dignity, but also public health.”
Even some doctors argue that the growing attention paid to long COVID is excessive.
“It’s often normal to experience mild fatigue or weaknesses for weeks after being sick and inactive and not eating well. Calling these cases long COVID is the medicalization of modern life,” Marty Makary, MD, a surgeon and public policy researcher at Johns Hopkins University, Baltimore, wrote in a commentary in the Wall Street Journal.
Other doctors strongly disagree, including Alba Azola, MD, codirector of the Johns Hopkins Post-Acute COVID-19 Team and an expert in the stigma surrounding long COVID.
“Putting that spin on things, it’s just hurting people,” she says.
One example is people who cannot return to work.
“A lot of their family members tell me that they’re being lazy,” Dr. Azola says. “That’s part of the public stigma, that these are people just trying to get out of work.”

Can siRNA improve compliance in patients with hypertension?
Many approaches have been explored in recent years to make life easier for patients living with chronic conditions that require them to take daily medication: subcutaneous implantable devices, nanogels, and, more specifically in the case of hypertension, renal denervation or small interfering RNA (siRNA) with a long half-life.
It’s siRNA that Michel Azizi, MD, PhD, head of the blood pressure clinic at Georges Pompidou European Hospital (HEGP) in Paris, discussed at the International Meeting of the French Society of Hypertension.
These small molecules have already shown their worth in treating rare diseases such as transthyretin amyloidosis. More recently, treating hypercholesterolemia with the PCSK9 inhibitor inclisiran has proven effective. “One subcutaneous injection of inclisiran reduces LDL cholesterol by 50% for a period of 210 days,” said Dr. Azizi.
The benefit of a new therapeutic siRNA – zilebesiran, administered subcutaneously – in treating hypertension is currently the subject of a phase II clinical trial.
This is a double-stranded RNA. One of the strands is linked to a sugar, N-acetylgalactosamine (GalNAc), which protects these highly fragile siRNA and binds with a very strong affinity in the liver. The second strand binds to a specific area of the RNA to prevent synthesis of the precursor peptide of angiotensin, angiotensinogen. The resulting effect is suppression of the production of angiotensin I and II, which leads to a long-lasting lowering of blood pressure.
Lasting efficacy
Phase I studies with zilebesiran have demonstrated a long-term effect, with a reduction of greater than 90% in circulating angiotensinogen over 6 months after a single subcutaneous dose (800 mg). The peak in reduction of circulating angiotensinogen occurs after approximately 3 weeks.
“It’s extremely powerful,” said Dr. Azizi.
Lasting reductions in blood pressure have also been observed, with 24-hour ambulatory blood pressure monitoring showing a reduction in systolic BP of greater than 15 mm Hg 8 weeks after administration of a single dose of zilebesiran (800 mg).
Zilebesiran was also well tolerated, with only mild to moderate reactions at the site of the injection (n = 5/56) and no serious treatment-related adverse events, hypotension, or significant changes in kidney or liver function.
“In terms of benefits, the effect is ongoing. Zilebesiran leads to reduced medication use and causes less variability in blood pressure response. Nevertheless, interfering RNA acts slowly, meaning that zilebesiran would not be suitable for people presenting with a hypertensive crisis. The fact that it blocks the renin-angiotensin system [RAS] for a very long period of time also poses the question of how to reverse its hypotensive effects,” said Dr. Azizi.
Unanswered questions
The lasting RAS antagonist and blood pressure–lowering effects pose a potential safety problem in circumstances involving patients in a state of hypovolemia and hypotension who require rapid blood pressure–raising interventions to prevent morbidity and mortality.
In recent studies, Estrellita Uijl et al. have thus examined strategies to counteract the blood pressure–lowering effect of siRNA in spontaneously hypertensive rats.
Fludrocortisone and a high-salt diet were both successful in gradually increasing blood pressure, which returned to its baseline levels on days 5 and 7, respectively. Yet this rate of response would be wholly inadequate in an urgent clinical situation.
However, midodrine could not reduce blood pressure to normal levels, whether administered subcutaneously or orally.
A rapid and short-lasting increase in blood pressure was observed with bolus doses of vasopressors, but clinically, these would need to be administered intravenously to achieve a lasting effect. Such administration would require hospitalization, close monitoring, and the use of human resources and additional health care provisions.
Encouragingly, the laboratory that created this molecule, Alnylam Pharmaceuticals, has come up with an antidote: Reversir. It is a GalNAc-conjugated, single-stranded, high-affinity oligonucleotide complementary to the zilebesiran strand that achieves effective reversal of siRNA activity in 24 hours.
In the future, after the phase 2 trials have been completed, whether or not zilebesiran reduces the incidence of cardiovascular events and mortality remains to be seen. But as for Dr. Azizi, the director of HEGP’s blood pressure clinic in Paris, he has no doubt that “this approach is about to shake up how we treat patients in the cardiovascular field.”
On the horizon
Zilebesiran is being studied in phase 2 trials in patients with mild to moderate hypertension not taking antihypertensive drugs (KARDIA-1: 375 patients; double-blind, placebo-controlled, five-arm trial; zilebesiran at 150, 300, and 600 mg twice per year and 300 mg once every 3 months) and in patients whose blood pressure is not controlled (KARDIA-2: 800 patients; initial open-label start-up period of 4 weeks with indapamide/amlodipine/olmesartan, followed by a double-blind, placebo-controlled study over 6 months, then an open-label extension study for up to 12 additional months; zilebesiran at 600 mg on the first day of the initial double-blind period, then every 6 months during the open-label extension period).

Metformin monotherapy not always best start in type 2 diabetes
Metformin failure in people with type 2 diabetes is very common, particularly among those with high hemoglobin A1c levels at the time of diagnosis, new findings suggest.
An analysis of electronic health record data for more than 22,000 patients starting metformin at three U.S. clinical sites found that over 40% experienced metformin failure.
This was defined as either failure to achieve or maintain A1c less than 7% within 18 months or the use of additional glucose-lowering medications.
Other predictors that metformin use wouldn’t be successful included increasing age, male sex, and race/ethnicity. However, the latter ceased to be linked after adjustment for other clinical risk factors.
“Our study results suggest increased monitoring with potentially earlier treatment intensification to achieve glycemic control may be appropriate in patients with clinical parameters described in this paper,” Suzette J. Bielinski, PhD, and colleagues wrote.
“Further, these results call into question the ubiquitous use of metformin as the first-line therapy and suggest a more individualized approach may be needed to optimize therapy,” they added in their article, published online in the Journal of Clinical Endocrinology and Metabolism.
The study is also noteworthy in that it demonstrated the feasibility of using EHR data with a machine-learning approach to discover risk biomarkers, Dr. Bielinski, professor of epidemiology at the Mayo Clinic, Rochester, Minn., said in an interview.
“We wanted to repurpose clinical data to answer questions ... I think more studies using these types of techniques repurposing data meant for one thing could potentially impact care in other domains. ... If we can get the bang for the buck from all these data that we generate on people I just think it will improve health care and maybe save health care dollars.”
Baseline A1c strongest predictor of metformin failure
The investigators identified a total of 22,047 metformin initiators from three clinical primary care sites: the University of Mississippi’s Jackson centers, which serves a mostly African American population, the Mountain Park Health Center in Arizona, a seven-clinic federally qualified community health center in Phoenix that serves a mostly Latino population, and the Rochester Epidemiology Project, which includes the Mayo Clinic and serves a primarily White population.
Overall, a total of 43% (9,407) of patients met one of two criteria for metformin failure by 18 months. Among those, median time to failure on metformin was 3.9 months.
Unadjusted failure rates were higher among African Americans, Hispanics, and other racial groups, compared with non-Hispanic White patients.
However, the racial groups also differed by baseline characteristics. Mean A1c was 7.7% overall, 8.1% for the African American group, 7.9% for Asians, and 8.2% for Hispanics, compared with 7.6% for non-Hispanic Whites.
Of 150 clinical factors examined, higher A1c was the strongest predictor of metformin failure, with a rapid increase in risk appearing between 7.5% and 8.0%.
“The slope is steep. It gives us some clinical guidance,” Dr. Bielinski said.
Other variables positively correlated with metformin failure included “diabetes with complications,” increased age, and higher levels of potassium, triglycerides, heart rate, and mean cell hemoglobin.
Factors inversely correlated with metformin failure were having received screening for other suspected conditions and medical examination/evaluation, and lower levels of sodium, albumin, and HDL cholesterol.
Three variables – body mass index, LDL cholesterol, and creatinine – had a U-shaped relationship with metformin failure, so that both high and low values were associated with increased risk.
“The racial/ethnic differences disappeared once other clinical factors were considered suggesting that the biological response to metformin is similar regardless of race/ethnicity,” Dr. Bielinski and colleagues wrote.
They also noted that the abnormal lab results which correlated with metformin failure “likely represent biomarkers for chronic illnesses. However, the effect size for lab abnormalities was small compared with that of baseline A1c.”
Dr. Bielinski urged caution in interpreting the findings. “Electronic health records data have limitations. We have evidence that these people were prescribed metformin. We have no idea if they took it. ... I would really be hesitant to be too strong in making clinical recommendations.”
However, she said that the data are “suggestive to say maybe we need to have some kind of threshold where if someone comes in with an A1c of X that they go on dual therapy right away. I think this is opening the door to that.”
The authors reported no relevant financial relationships.

“Our study results suggest increased monitoring with potentially earlier treatment intensification to achieve glycemic control may be appropriate in patients with clinical parameters described in this paper,” Suzette J. Bielinski, PhD, and colleagues wrote.
“Further, these results call into question the ubiquitous use of metformin as the first-line therapy and suggest a more individualized approach may be needed to optimize therapy,” they added in their article, published online in the Journal of Clinical Endocrinology and Metabolism.
The study is also noteworthy in that it demonstrated the feasibility of using EHR data with a machine-learning approach to discover risk biomarkers, Dr. Bielinski, professor of epidemiology at the Mayo Clinic, Rochester, Minn., said in an interview.
“We wanted to repurpose clinical data to answer questions ... I think more studies using these types of techniques repurposing data meant for one thing could potentially impact care in other domains. ... If we can get the bang for the buck from all these data that we generate on people I just think it will improve health care and maybe save health care dollars.”
Baseline A1c strongest predictor of metformin failure
The investigators identified a total of 22,047 metformin initiators from three clinical primary care sites: the University of Mississippi’s Jackson centers, which serves a mostly African American population, the Mountain Park Health Center in Arizona, a seven-clinic federally qualified community health center in Phoenix that serves a mostly Latino population, and the Rochester Epidemiology Project, which includes the Mayo Clinic and serves a primarily White population.
Overall, a total of 43% (9,407) of patients met one of two criteria for metformin failure by 18 months. Among those, median time to failure on metformin was 3.9 months.
Unadjusted failure rates were higher among African Americans, Hispanics, and other racial groups, compared with non-Hispanic White patients.
However, the racial groups also differed by baseline characteristics. Mean A1c was 7.7% overall, 8.1% for the African American group, 7.9% for Asians, and 8.2% for Hispanics, compared with 7.6% for non-Hispanic Whites.
Of 150 clinical factors examined, higher A1c was the strongest predictor of metformin failure, with a rapid increase in risk appearing between 7.5% and 8.0%.
“The slope is steep. It gives us some clinical guidance,” Dr. Bielinski said.
Other variables positively correlated with metformin failure included “diabetes with complications,” increased age, and higher levels of potassium, triglycerides, heart rate, and mean cell hemoglobin.
Factors inversely correlated with metformin failure were having received screening for other suspected conditions and medical examination/evaluation, and lower levels of sodium, albumin, and HDL cholesterol.
Three variables – body mass index, LDL cholesterol, and creatinine – had a U-shaped relationship with metformin failure, so that both high and low values were associated with increased risk.
“The racial/ethnic differences disappeared once other clinical factors were considered suggesting that the biological response to metformin is similar regardless of race/ethnicity,” Dr. Bielinski and colleagues wrote.
They also noted that the abnormal lab results which correlated with metformin failure “likely represent biomarkers for chronic illnesses. However, the effect size for lab abnormalities was small compared with that of baseline A1c.”
Dr. Bielinski urged caution in interpreting the findings. “Electronic health records data have limitations. We have evidence that these people were prescribed metformin. We have no idea if they took it. ... I would really be hesitant to be too strong in making clinical recommendations.”
However, she said that the data are “suggestive to say maybe we need to have some kind of threshold where if someone comes in with an A1c of X that they go on dual therapy right away. I think this is opening the door to that.”
The authors reported no relevant financial relationships.

Can 6 minutes of intense cycling put the brakes on Alzheimer’s?
new research suggests.
In a small study of healthy adults, 6 minutes of high-intensity cycling increased circulating levels of brain-derived neurotrophic factor (BDNF) to a significantly greater extent than prolonged light cycling or fasting.
However, the data do not suggest that 6 minutes of high-intensity exercise “wards off dementia,” cautioned lead investigator Travis Gibbons, MSc, PhD candidate in environmental physiology at the University of Otago (New Zealand), Dunedin, and now postdoctoral fellow at the University of British Columbia – Okanagan, Kelowna.
“Like all science, this is just a small piece that supports a potential mechanistic role for how exercise might improve brain health,” Dr. Gibbons told this news organization.
The findings were published online in the Journal of Physiology.
Targeting BDNF
Both intermittent fasting and exercise have previously been shown to have potent neuroprotective effects; and an acute upregulation of BDNF appears to be a common mechanistic link.
To tease apart the influence of fasting and exercise on BDNF production, Dr. Gibbons and colleagues studied 12 aerobically fit, healthy men (n = 6) and women (n = 6) aged 20-40 years.
In a study that employed a repeated-measures crossover design, they assessed circulating BDNF levels after a 20-hour fast, prolonged (90-min) light cycling, short (6-min) high-intensity cycling, and combined fasting and exercise.
Six minutes of high-intensity exercise appeared to be the most efficient way to increase BDNF.
Fasting for 20 hours led to a ninefold increase in ketone body delivery to the brain but had no effect on any metric of BDNF in peripheral circulation at rest or during exercise.
Six minutes of high-intensity exercise increased every metric of circulating BDNF four to five times more than prolonged low-intensity exercise.
In addition, the increase in plasma-derived BDNF correlated with a sixfold increase in circulating lactate irrespective of feeding or fasting state.
Lactate delivery?
“My leading theory is that, during and following intense exercise, lactate produced by muscles is delivered and consumed by the brain,” Dr. Gibbons noted.
“It takes high-intensity exercise to provoke this ‘cerebral substrate switch’ from glucose to lactate. Critically, this cerebral substrate switch has been shown to contribute to the early processes that upregulate BDNF production in the brain,” he said.
However, “Whether this translates to ‘warding off dementia’ is not clear,” Dr. Gibbons added.
The study also suggests that increases in plasma volume and platelet concentration appear to play a role in concentrating BDNF in the circulation during exercise.
The investigators note that BDNF and other neurotrophic-based pharmaceutical therapies have shown “great promise” in slowing and even arresting neurodegenerative processes in animals, but attempts to harness the protective power of BDNF in human neurodegeneration have thus far failed.
“Whether episodically upregulating BDNF production with intense exercise is an effective strategy to curb age-related cognitive decline in humans is unknown, but animal models indicate that it is and that BDNF plays a primary role,” the researchers write.
Funding for the study was provided by the Healthcare Otago Charitable Trust. The investigators have reported no relevant financial relationships.

Singer is paralyzed after delay in care; hospital must pay
Delay in treatment will cost hospital millions
WFAA.com, among other news sites.
according to a report onOn March 21, 2019, Judy “Jessie” Adams, then part of a singing-songwriting duo with her husband, Richard, went to Premier Interventional Pain Management, in Flower Mound, Tex., prior to the couple’s drive to Ohio for a funeral. At Premier, Jesse received an epidural steroid injection (ESI) that she hoped would ease her back pain during the long drive.
Instead, the injection ended up increasing her pain.
“He [the pain physician] gave me the shot, but I couldn’t feel my legs. They were tingling, but I couldn’t feel them,” Mrs. Adams explained. “The pain was so bad in my back.” In their suit, Adams and her husband alleged that the doctor had probably “nicked a blood vessel during the ESI procedure, causing Jessie to hemorrhage.” (The couple’s suit against the doctor was settled prior to trial.)
Mrs. Adams remained under observation at the pain facility for about 1½ hours, at which point she was taken by ambulance to nearby Texas Health Presbyterian Hospital. There, in the emergency department, staff ordered a “STAT MRI” in preparation for an emergency laminectomy.
For reasons that remain murky, the MRI wasn’t performed for 1 hour and 37 minutes. The emergency laminectomy itself wasn’t started until more than 5 hours after Adams had been admitted to the ED. This was a direct violation of hospital protocol, which required that emergency surgeries be performed within 1 hour of admittance in the first available surgical suite. (At trial, Mrs. Adams’s attorneys from Lyons & Simmons offered evidence that a suite became available 49 minutes after Adams had arrived at the ED.)
During the wait, Mrs. Adams continued to experience excruciating pain. “I kept screaming: ‘Help me,’ ” she recalled. At trial, her attorneys argued that the hospital’s delay in addressing her spinal emergency led directly to her current paralysis, which keeps her confined to a wheelchair and renders her incontinent.
The hospital disagreed. In court, it maintained that Mrs. Adams was already paralyzed when she arrived at the ED and that there was no delay in care.
The jury saw things differently, however. Siding with the plaintiffs, it awarded Mrs. Adams and her husband $10.1 million, including $500,000 for Mr. Adams’s loss of future earnings and $1 million for his “loss of consortium” with his wife.
Their music career now effectively over, Mr. Adams spends most of his time taking care of Mrs. Adams.
“Music was our lifeblood for so many years, and he can’t do it anymore,” Mrs. Adams said. “He goes upstairs to play his guitar and write, and suddenly I need him to come and cath me. I just feel like I’m going to wake up from this bad dream, but it’s the same routine.”
Two doctors are absolved in woman’s sudden death
In a 3-2 decision in December 2022, the Pennsylvania Supreme Court ruled that the state’s 2-year statute of limitations in wrongful-death cases applies even in cases in which plaintiffs fail to identify the cause of death in a timely manner, as a report in the Claims Journal indicates.
The decision stems from a lawsuit filed by Linda Reibenstein on behalf of her mother, Mary Ann Whitman, who died in late April 2010 from a ruptured aortic aneurysm.
On April 12, 2010, Ms. Whitman visited Patrick D. Conaboy, MD, a Scranton family physician, complaining of a persistent cough, fever, and lower-back pain. Following an initial examination, Dr. Conaboy ordered an aortic duplex ultrasound scan and a CT scan of the patient’s abdomen.
The ultrasound was performed by radiologist Charles Barax, MD, who reviewed both scans. He identified a “poorly visualized aortic aneurysm.” At this point, Dr. Conaboy referred Ms. Whitman to a vascular surgeon. But before this visit could take place, Whitman’s aneurysm ruptured, killing her. This was listed as the medical cause of death on the patient’s death certificate.
In April 2011, Ms. Reibenstein filed a claim against Dr. Barax, alleging that he had failed to gauge the severity of her mother’s condition. Ms. Reibenstein’s attorney wasn’t able to question Dr. Barax on the record until well after the state’s 2-year statute of limitations had elapsed. When he did testify, Dr. Barax explained that the scans’ image quality prevented him from determining whether Whitman’s aneurysm was rupturing or simply bleeding. Despite this, he insisted that he had warned Dr. Conaboy of the potential for Ms. Whitman’s aneurysm to rupture.
In March 2016, nearly 6 years after her mother’s death, Ms. Reibenstein filed a new lawsuit, this one against Dr. Conaboy, whom she alleged had failed to properly treat her mother’s condition. Dr. Conaboy, in turn, asked the court for summary judgment – that is, a judgment in his favor without a full trial – arguing that the state’s window for filing a wrongful-death claim had long since closed. For their part, Ms. Reibenstein and her attorney argued that the state’s 2-year statute of limitations didn’t start until the plaintiff had discovered the cause of her mother’s death.
Initially refusing to dismiss the case, a lower court reconsidered Dr. Conaboy’s motion for summary judgment and ruled that Ms. Reibenstein had failed to present any evidence of “affirmative misrepresentation or fraudulent concealment.” In other words, in the absence of any willful attempt on the part of the defendant to hide the legal cause of death, which includes “acts, omissions, or events having some causative connection with the death,” the statute of limitations remained in effect, and the defendant’s motion was thereby granted.
Continuing the legal seesaw, a state appeals court reversed the lower-court ruling. Noting that the Pennsylvania malpractice statute was ambiguous, the court argued that it should be interpreted in a way that protects plaintiffs who seek “fair compensation” but encounter willfully erected obstacles in pursuit of their claim.
Dr. Conaboy then took his case to the state’s highest court. In its majority decision, the Pennsylvania Supreme Court staked out a narrow definition of cause of death – one based on the death certificate – and ruled that only willful fraud in that document would constitute the necessary condition for halting the claim’s clock. Furthermore, the high court said, when lawmakers adopted the Medical Care Availability and Reduction of Error Act in 2002, they did so with no guarantee “that all of the information necessary to sustain a claim will be gathered in the limitations period.”
Similarly, the court ruled, “at some point the clock must run out, lest health care providers remain subject to liability exposure indefinitely, with the prospect of a trial marred by the death or diminished memory of material witnesses or the loss of critical evidence.”
