Endoscopic full-thickness resection (eFTR) of complex colorectal lesions appears safe and effective, based on prospective data from 20 Dutch hospitals.

Macroscopic complete en bloc resection was achieved in 83.9% of procedures with an adverse event rate of 9.3%, reported lead author Liselotte W. Zwager, a PhD candidate at the University of Amsterdam, and colleagues.

“With the advantage of enabling a transmural resection, eFTR offers an alternative to radical surgery in lesions considered incurable with current resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD),” the investigators wrote in Endoscopy.

But more data are needed for widespread adoption, they noted. “Several studies have reported encouraging results on the short-term safety and efficacy of eFTR for numerous indications. However, firm conclusions on clinical results will require analysis of large prospective series of patients in everyday clinical practice.”

The present study provided data from 362 patients who underwent 367 procedures at 5 academic and 15 nonacademic centers in the Netherlands.

Patients were eligible for eFTR if polyps were nonlifting or in difficult-to-reach locations, or if T1 colorectal cancer (CRC) was suspected. In addition, eFTR was performed for subepithelial tumors, and as secondary completion treatment after incomplete endoscopic resection of T1 CRC with a positive or nonassessable resection margin. Lesions greater than 30 mm were excluded because of device diameter constraints.

The primary outcome was macroscopic complete en bloc resection. Secondary outcomes included adverse events, full-thickness resection rate, and clinical success, the latter of which was defined by tumor-free resection margins (R0).

Out of 367 procedures, eFTR was most frequently conducted because of incomplete resection of T1 CRC (41%), followed by nonlifting or difficult-to-reach polyps (36%), suspected T1 CRC (19%), and least often, subepithelial tumors (4%).

Complete en bloc resection was achieved in 83.9% of procedures. Excluding 21 procedures in which eFTR was not performed because of inaccessibility of the lesion (n = 7) or immobility of tissue prohibiting retraction of the lesion into the cap (n = 14), R0 was achieved in 82.4% of cases. Among the same group, full-thickness resection rate was comparable, at 83.2%.

Adverse events occurred in 34 patients (9.3%), among whom 10 (2.7%) underwent emergency surgery for perforations or appendicitis.

“In conclusion,” the investigators wrote, “eFTR is an exciting, innovative resection technique that is clinically feasible and safe for complex colorectal lesions, with the potential to obviate the need for surgical resection. Further efficacy studies on eFTR as a primary and secondary treatment option for T1 CRC are needed, focusing on both the short- and long-term oncologic results.”

Peter V. Draganov, MD, of the University of Florida, Gainesville, called the R0 resection rate “respectable,” and suggested that the study “reconfirms on a larger scale that eFTR with the full-thickness resection device is successful in the majority of cases.”

“The full-thickness resection device expands our armamentarium to remove difficult polyps and early CRC,” he said.

Still, Dr. Draganov, who has previously advised careful patient selection for eFTR, noted certain drawbacks of the technique. “The presented data highlight some of the limitations of the full-thickness resection device, including the relatively small size of the lesion [median diameter, 23 mm] that can be resected, and challenges related to accessing and capturing the lesion due to the limited visibility and maneuverability of the device.”

Ultimately, Dr. Draganov supported the investigators’ call for more data. “Before eFTR becomes a primary modality for management of T1 CRC, we do need follow-up data on long-term cancer-related outcomes,” he said.

The study was supported by Ovesco Endoscopy. The investigators disclosed additional relationships with Cook, Ethicon, Olympus, and others.

The DAPA-HF trial has already changed cardiology in opening up a new class of drugs to patients with heart failure (HF), whether or not they have diabetes. Now the trial is yielding clues as to how it benefits them. For now, it’s doing so by process of elimination.

A new analysis suggests that dapagliflozin (Farxiga, AstraZeneca) didn’t need help from loop diuretics to cut the risk for clinical events in patients with HF with reduced ejection fraction (HFrEF), a benefit seen across the spectrum of glycosylated hemoglobin levels and without compromising renal function, said DAPA-HF investigators. Also, use of dapagliflozin and its clinical effects were not associated with changes in loop diuretic dosage. Those findings and others suggest the drug helps in HFrEF at least partly by some other mechanism than its own diuretic effect, the researchers say.

Such insights will likely be important to case-by-case decisions on whether to use the drug, a sodium-glucose cotransporter 2 (SGLT2) inhibitor once reserved for patients with diabetes, given the recently broader landscape of HF treatment options.

As previously reported from DAPA-HF, with more than 4,700 patients, those who received dapagliflozin showed significant reductions in the primary end point, a composite of cardiovascular (CV) death, HF hospitalization, and urgent HF visit requiring IV therapy over about 18 months. The 45% of patients with and 55% without type 2 diabetes enjoyed about equal benefit in the placebo-controlled trial for that end point, as well as for all-cause mortality.

SGLT2 inhibitors work in diabetes by promoting urinary glucose excretion. That had led some to speculate that its benefit in HFrEF comes primarily from a diuretic effect; the current findings largely put that question to rest.

“Our findings show that treatment with dapagliflozin was effective regardless of diuretic use or diuretic dose. They also show that dapagliflozin did not lead to an increase in renal adverse events or discontinuation of therapy in patients treated with a diuretic,” trialist Alice M. Jackson, MB, ChB, said in an interview.

“In fact, renal adverse events were generally less common in patients treated with dapagliflozin, across the diuretic categories,” said Dr. Jackson, from the University of Glasgow.

Dr. Jackson presented the new analysis at a Late-Breaking Science Session during the European Society of Cardiology Heart Failure Discoveries virtual meeting. The HFA sessions were conducted virtually this year due to the COVID-19 pandemic.

At baseline, 84% of patients were on conventional diuretics. The post hoc analysis broke out all patients by loop-diuretic dosage level: none; less than 40 mg furosemide equivalents (FE); 40 mg FE; or more than 40 mg FE. Clinical outcomes were similar across the four groups.

Clinicians in the trial “were not given specific advice about adjusting diuretic doses, but were encouraged to assess volume status and make changes to medical therapy based on this, if necessary,” Dr. Jackson said. “This suggests that, for most patients, starting dapagliflozin will not necessitate a change in diuretic dose.”

With the caveat that the event rate was low in the relatively few patients not prescribed loop diuretics, she said, “the magnitude of the benefit from dapagliflozin appeared to be larger in patients not treated with a diuretic.”

There was no suggestion of a diuretic dose–response effect or statistical interaction between diuretic use and clinical outcomes on dapagliflozin, Dr. Jackson observed in the interview.

Of note in the analysis, hematocrit levels shot up soon after patients started active therapy, but they didn’t rise much in the placebo group. The sustained hematocrit elevation on dapagliflozin, seen at all diuretic dosage levels, persisted even after dosage reductions at 6 months, she said.

“Dapagliflozin is effective in HFrEF irrespective of background diuretic therapy; therefore, it is almost certainly not purely acting as a diuretic,” Andrew J. Coats, MD, DSc, MBA, said in an interview.

The findings also “lessen the concern that dapagliflozin’s beneficial effects are only seen only in patients without effective diuretic dosing,” said Dr. Coats, from University of Warwick, Coventry, England.

“Altogether, these data give further reassurance that dapagliflozin can safely be used in heart failure, and has a beneficial effect independent of the use of diuretic drugs,” invited discussant Wolfram Doehner, MD, PhD, Charité-Universitätsmedizin Berlin, said after Dr. Jackson’s presentation of the analysis.

He made special mention of the sustained hematocrit elevation on dapagliflozin. “While this effect may likely relate to the mild reduction in plasma volume secondary to dapagliflozin therapy, it is noted that the increase in hematocrit was independent of any change of the diuretic dose,” Doehner said. “If additional mechanisms have a role for this observed increase in hematocrit, it may be of interest in further investigations.”

Dr. Jackson pointed to several observations that suggest the hematocrit finding isn’t explained by hemoconcentration from reduced plasma volume, at least not entirely.

For example, hematocrit levels rose “without any suggestion of a relationship between diuretic dose and degree of hematocrit elevation with dapagliflozin,” she said.

The elevations persisted even with diuretic dose reductions at 6 and 12 months, “which should have led to a decrease in hemoconcentration if it was caused by volume contraction.”

Also, she said, “among patients not taking a diuretic, volume depletion occurred less frequently in the dapagliflozin group than in the placebo group, but there was still a similar rise in hematocrit with dapagliflozin.”

Both Dr. Jackson and Dr. Coats said the sustained elevation in hematocrit on the drug is unlikely to pose a major hazard.

Dr. Coats said that, theoretically, “increased hematocrit could reduce peripheral vessel blood flow, making ischemia and thrombosis more likely. But the size of the effect is small and unlikely to be clinically important.”

A diuretic dose could not be determined for 128 of the trial’s 4,744 randomized patients with HFrEF, so the post hoc analysis was limited to the remaining 4,616. Of those, 746 were not on diuretics at baseline, 1,311 were on loop diuretics at less than 40 mg FE or on non-loop diuretics only, 1,365 were taking 40 mg FE, and 1,204 were on higher doses of loop diuretics.

The mean baseline dosage was 60 mg FE, which rose slightly throughout the trial. But the baseline dosage and the increases were both similar in the placebo and dapagliflozin groups. Dr. Jackson said 84% and 83% of patients on dapagliflozin and placebo, respectively, maintained their baseline dose at 6 months and about 77% in both groups at 12 months.

The overall trial’s significant primary endpoint reduction for dapagliflozin versus placebo applied similarly to patients not on a diuretics and to those on any dose of diuretic, with an interaction P value of .23 for the effect of diuretic use. The hazard ratios (95% confidence interval) were 0.57 (0.36-0.92) for patients not on diuretics, 0.78 (0.68-0.90) for patients on any diuretic dosage, and 0.74 (0.65-0.85) overall

Dr. Jackson said during her formal online presentation that patients on diuretics showed a “tendency toward slightly more volume depletion in those on dapagliflozin than in those on placebo, but the excess was small and not greater than approximately 3% in those taking 40 mg furosemide equivalent diuretic. And fortunately, this did not result in an increase in frequency in renal adverse events nor of discontinuation of study drug.”

Of those, 746 were not on diuretics at baseline, 1,311 were on loop diuretics at less than 40 mg FE or on non-loop diuretics only, 1,365 were taking 40 mg FE, and 1,204 were on higher doses of loop diuretics.

The mean baseline dosage was 60 mg FE, which rose slightly throughout the trial. But the baseline dosage and the increases were both similar in the placebo and dapagliflozin groups. Dr. Jackson said 84% and 83% of patients on dapagliflozin and placebo, respectively, maintained their baseline dose at 6 months and about 77% in both groups at 12 months.

The overall trial’s significant primary endpoint reduction for dapagliflozin versus placebo applied similarly to patients not on a diuretics and to those on any dose of diuretic, with an interaction P value of .23 for the effect of diuretic use. The hazard ratios (95% confidence interval) were 0.57 (0.36-0.92) for patients not on diuretics, 0.78 (0.68-0.90) for patients on any diuretic dosage, and 0.74 (0.65-0.85) overall

Dr. Jackson said during her formal online presentation that patients on diuretics showed a “tendency toward slightly more volume depletion in those on dapagliflozin than in those on placebo, but the excess was small and not greater than approximately 3% in those taking 40 mg furosemide equivalent diuretic. And fortunately, this did not result in an increase in frequency in renal adverse events nor of discontinuation of study drug.”

Despite a lack of financial penalties, the U.S. Veterans Affairs Health Care System has seen a steady 15% reduction in 30-day all-cause readmissions for patients admitted for heart failure, with no concurrent increase in 30-day mortality, a large cohort study suggests.

Unlike the Center for Medicare & Medicaid’s Hospital Readmissions Reduction Program (HRRP), whose primary objective is reducing payments to hospitals with excess readmissions, the VA’s efforts to reduce readmissions across their system did not include any financial penalties.

“The intervention focused on encouraging participation in transitions of care programs, such as the American College of Cardiology’s Hospital to Home Initiative and the creation of a heart failure provider network that included more than 900 heart failure providers throughout the VA system,” said the study’s lead author Justin T. Parizo, MD, of Stanford (Calif.) University.

The only measuring sticks the VA used were the public reporting of 30-day readmission rates (starting in 2012) and inclusion of those rates into hospitals’ overall star ratings (starting in 2014).  

“The readmissions reductions we saw were similar in magnitude to those seen in patients in CMS fee-for-service categories in the HRRP,” said Dr. Parizo. “And while we had no ability to evaluate causality here, our best guess from what we can see is that there’s been no impact of the readmissions program on mortality,” he added.

Their results were published online June 17 in JAMA Cardiology.

Dr. Parizo and colleagues conducted a cohort study of 304,374 heart failure hospital admissions in 164,566 patients from January 2007 to September 2017. Importantly, he stressed, the researchers were able to do sophisticated risk adjustment for illness trends, something that has been a sticking point in some of the HRRP studies to date.

“We leveraged the robust dataset that the VA provides to adjust for illness severity. Accounting for clinical factors, like blood pressure, weight, creatinine, BNP [B-type natriuretic peptide], and other markers of heart failure severity, but also for changes in coding,” said Dr. Parizo.

Stratification according to left ventricular ejection fraction (LVEF) showed similar results both in terms of 30-day readmission and 30-day mortality for those with LVEF of 40% or greater and those with LVEF less than 40%.

In an interview, Dr. Parizo noted that they actually saw a small but significant uptick in mortality in the 2011-2012 period (compared with 2007-2008) that remains unexplained. “By the 2015-2017 period, 30-day death had returned to baseline levels,” he said.

In contrast, the HRRP, which was rolled out in 2012, has also been shown to reduce readmissions but, in most studies, 30-day mortality had gone up.

“The VA has a very robust quality infrastructure and a robust mechanism for prioritizing certain quality-improvement goals and getting them accomplished that I think they are underrecognized for,” said Leora Horwitz, MD, MHS, the director of the Center for Healthcare Innovation and Delivery Science at NYU Langone Medical Center, New York.

In an interview, she also noted some concern with the uptick seen in the 2011-2012 period, noting that the increase might be the same signal seen with the HRRP intervention.

“This is around the same time period where other people were writing the HRRP papers that showed an increase in mortality, so that’s something to consider,” she said.

Dr. Horwitz coauthored a study published in 2017 indicating that, on a hospital level (compared with a patient level, the approach most other studies took), reductions in readmissions were only weakly correlated with 30-day mortality rates after discharge.

“So, if you think that a hospital that’s behaving badly and keeping people out of the hospital inappropriately to cut down their readmissions, you’d expect to see increased mortality in that hospital, and in our study there was no correlation whatsoever. So there is still debate as to what is behind the increase in mortality on a patient level with heart failure that we’ve seen in some studies,” she said.

Dr. Horwitz doubts an intervention such as the one undertaken in the VA system – even with its fairly soft-touch “name and shame” component – would work in the non-VA hospital world.

“Those who have been in favor of financial penalties have pointed to the fact that, in general, it’s hard to get health systems to respond without financial alignment, even if it’s not an overt financial incentive,” she said.

“The VA is a unique environment,” she noted. “They have a very strong top-down command control focus where people are kind of used to being told, ‘OK, here are the measures we have to address this year.’ It’s good to see that the system that has worked for them for other outcomes also worked for them for heart failure readmissions too.”

Dr. Parizo has disclosed no relevant financial relationships. Dr. Horwitz has worked under contract to Medicare to develop readmission measures.

Here are the stories our MDedge editors across specialties think you need to know about today:

COVID-related care delays mean excess cancer deaths

There could be 10,000 excess deaths from breast and colorectal cancer over the next 10 years as a result of missed screenings, delays in diagnosis, and reductions in oncology care caused by the COVID-19 pandemic, according to predictions generated by a National Cancer Institute model.

The number of excess deaths per year would peak in the next year or two, likely sooner for colorectal cancer than for breast cancer.

In an editorial published June 19 in Science, NCI Director Norman “Ned” Sharpless, MD, highlighted the modeling. In an interview, he pointed out that this analysis is conservative because the researchers evaluated only two types of cancer. They chose breast and colorectal cancer because these are common cancers – accounting for about one-sixth of all cancers – with relatively high screening rates.

“We didn’t model other cancer types, but we have no reason to think that we’re not going to see the same thing with other types of malignancies,” he said. “That is a significant amount of excess mortality.” Read more.

Diabetes control in U.S. youth has worsened over time

Glycemic control among youth with diabetes is no better today than it was in 2002 and in some subgroups it’s worse, according to data reported at the virtual American Diabetes Association scientific sessions. This finding comes despite the increased availability of diabetes technology, newer therapies, and more aggressive recommended blood glucose targets.

A particularly striking data point was seen among youth who had type 2 diabetes for 10 years or more: average A1c skyrocketed from 7.9% in 2008-2013 to 10.1% in 2014-2019. The numbers were small, 25 patients in the earlier cohort and 149 patients in the later, yet the difference was still statistically significant.

“Our finding that current youth and young adults with diabetes are not demonstrating improved glycemic control, compared to earlier cohorts in the SEARCH study, was surprising given how the landscape of diabetes management has changed dramatically over the past decade,” Faisal S. Malik, MD, of the University of Washington, Seattle, and Seattle Children’s Research Institute, said in an interview. Read more.

CDC advisors approve flu vaccine recommendations for 2020-2021

A pair of new vaccines for adults aged 65 years and older will be available for the 2020-2021 flu season – Fluzone high-dose quadrivalent, which replaces the trivalent Fluzone high-dose and Fluad quadrivalent (Seqirus), according to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices.

At a virtual meeting on June 24, the committee voted unanimously to approve the vaccine recommendations for annual influenza immunization of all individuals aged 6 months and older. They also voted to accept some guidance and language changes to the recommendations. Read more.

How can we better engage black men as patients?

In a new commentary, Kevin M. Simon, MD, seeks to answer a key question: “How do psychiatrists and other mental health clinicians better engage men of color?” Dr. Simon, a psychiatrist at Boston Children’s Hospital, recommends creating a comfortable environment, allowing for storytelling, assuring confidentiality, being aware of nonverbal language, and being respectful.

“Those on the front lines providing mental health services should understand black men’s mental health from an ecological perspective. Beyond the emotional burden that mental illness imposes on the individual, there are more considerable interpersonal and societal implications for the state of black men’s mental health. As such, in our full capacity like other men, black men play an essential role within families, churches, neighborhoods, and organizations,” Dr. Simon wrote. Read more.

The Diagnosis: Epidermodysplasia Verruciformis 

Histopathologic examination demonstrated acanthosis and coarse hypergranulosis with enlarged keratinocytes exhibiting blue cytoplasmic discoloration (Figure), which was suggestive of acquired epidermodysplasia verruciformis (EV).  

Acquired EV is a rare dermatologic condition associated with specific human papillomavirus (HPV) types that presents with recalcitrant lesions most commonly in the setting of immunosuppression.¹ The most common HPV types associated with EV are HPV-5 and -8, but associations with HPV-3, -9, -10, -12, -14, -15, -17, -19 to -25, -36 to -38, -47, and -50 also have been reported.^1,2 Acquired EV has been identified in individuals with human immunodeficiency virus, as well as in immunosuppressed patients with organ transplantation, Hodgkin lymphoma, systemic lupus erythematosus, and IgM deficiency, and in patients taking immunosuppressive medications such as tumor necrosis factor α inhibitors.^1,3 The diagnosis is clinicopathological with potential polymerase chain reaction studies to identify underlying HPV types. 

Acquired EV presents as hypopigmented to red, tinea versicolor-like macules or as verrucous, flat-topped papules on the trunk, arms, and/or legs.⁴ Histopathology reveals viral epidermal cytopathic changes, blue cytoplasm, and coarse hypogranulosis.⁴ 

There is no standardized treatment regimen for acquired EV, and no single approach has proven to yield an efficacious clinical outcome. Topical treatment options include steroids, retinoids, immunomodulators, cryotherapy, and electrosurgery, whereas retinoids or interferon alfa have been used as oral systemic therapy. Photodynamic therapy also has been shown to improve symptoms.³ Combination therapy such as interferon alfa with zidovudine or imiquimod with oral isotretinoin has shown better results than any single treatment.⁴ Due to the underlying HPV infection and its role in promotion of skin cancer development, lesions can characteristically undergo malignant transformations into Bowen disease but most commonly invasive squamous cell carcinoma (SCC), with initial lesions preferentially affecting sun-exposed areas due to the synergistic effect of UV light with EV-HPV lesions. The EV-HPV strains ^{5, 8,} and 41 carry the highest oncogenic potential.5 Little is known of the true incidence of oncogenicity for acquired EV. Regardless, consistent sun protection and lifelong clinical examinations are critical for prognosis.⁵  

The differential diagnosis of EV presenting in a tattoo includes allergic contact dermatitis, cutaneous sarcoidosis, pityriasis versicolor, and SCC. The pathology is critical to differentiate between these entities. The most frequently reported skin reactions to tattoo ink include inflammatory diseases (eg, allergic contact dermatitis, granulomatous reaction) or infectious diseases (eg, bacterial, viral, fungal).⁶ Allergic contact dermatitis, typically red pigment, is a common tattoo reaction. The most common histologic feature, however, is spongiosis, which results from intercellular edema. It often is limited to the lower epidermis but may affect the upper layers if the reaction is severe.⁷ Cutaneous sarcoidosis is a great masquerader that can present in various ways; however, its salient features on pathology are noncaseating granuloma involving the basal cell layer and epithelioid granuloma consisting of Langerhans giant cells.⁸ Although pityriasis versicolor can present in young immunocompromised adults, histologically salient features are the presence of both spores and hyphae in the stratum corneum.⁹ Although immunosuppression is a known risk factor for SCC, it is characterized histologically by hyperkeratosis, parakeratosis, and acanthosis with thickened and elongated rete ridges. Scattered atypical cells and frequent mitoses are present.¹⁰

The most frequently reported skin reactions to tattoo ink include inflammatory diseases (eg, allergic contact dermatitis, granulomatous reaction) or infectious diseases (eg, bacterial, viral, fungal).⁶ Allergic contact dermatitis, typically red pigment, is a common tattoo reaction. The most common histologic feature, however, is spongiosis, which results from intercellular edema. It often is limited to the lower epidermis but may affect the upper layers if the reaction is severe.⁷ Cutaneous sarcoidosis is a great masquerader that can present in various ways; however, its salient features on pathology are noncaseating granuloma involving the basal cell layer and epithelioid granuloma consisting of Langerhans giant cells.⁸ Although pityriasis versicolor can present in young immunocompromised adults, histologically salient features are the presence of both spores and hyphae in the stratum corneum.⁹ Although immunosuppression is a known risk factor for SCC, it is characterized histologically by hyperkeratosis, parakeratosis, and acanthosis with thickened and elongated rete ridges. Scattered atypical cells and frequent mitoses are present.¹⁰ 

The Diagnosis: Epidermodysplasia Verruciformis 

Histopathologic examination demonstrated acanthosis and coarse hypergranulosis with enlarged keratinocytes exhibiting blue cytoplasmic discoloration (Figure), which was suggestive of acquired epidermodysplasia verruciformis (EV).  

Acquired EV is a rare dermatologic condition associated with specific human papillomavirus (HPV) types that presents with recalcitrant lesions most commonly in the setting of immunosuppression.¹ The most common HPV types associated with EV are HPV-5 and -8, but associations with HPV-3, -9, -10, -12, -14, -15, -17, -19 to -25, -36 to -38, -47, and -50 also have been reported.^1,2 Acquired EV has been identified in individuals with human immunodeficiency virus, as well as in immunosuppressed patients with organ transplantation, Hodgkin lymphoma, systemic lupus erythematosus, and IgM deficiency, and in patients taking immunosuppressive medications such as tumor necrosis factor α inhibitors.^1,3 The diagnosis is clinicopathological with potential polymerase chain reaction studies to identify underlying HPV types. 

Acquired EV presents as hypopigmented to red, tinea versicolor-like macules or as verrucous, flat-topped papules on the trunk, arms, and/or legs.⁴ Histopathology reveals viral epidermal cytopathic changes, blue cytoplasm, and coarse hypogranulosis.⁴ 

There is no standardized treatment regimen for acquired EV, and no single approach has proven to yield an efficacious clinical outcome. Topical treatment options include steroids, retinoids, immunomodulators, cryotherapy, and electrosurgery, whereas retinoids or interferon alfa have been used as oral systemic therapy. Photodynamic therapy also has been shown to improve symptoms.³ Combination therapy such as interferon alfa with zidovudine or imiquimod with oral isotretinoin has shown better results than any single treatment.⁴ Due to the underlying HPV infection and its role in promotion of skin cancer development, lesions can characteristically undergo malignant transformations into Bowen disease but most commonly invasive squamous cell carcinoma (SCC), with initial lesions preferentially affecting sun-exposed areas due to the synergistic effect of UV light with EV-HPV lesions. The EV-HPV strains ^{5, 8,} and 41 carry the highest oncogenic potential.5 Little is known of the true incidence of oncogenicity for acquired EV. Regardless, consistent sun protection and lifelong clinical examinations are critical for prognosis.⁵

About one in five adolescents has thought about suicide, about 10% have experienced serious suicidal ideation, and 7% have attempted suicide by age 20 years, according to a longitudinal study of Canadian adolescents published online in Pediatrics.

In multivariable analyses, depression and anxiety were independently associated with passive and serious suicidal ideation at some ages, but none of the externalizing problems were significantly associated with passive or serious suicidal ideation. However, “both depressive and conduct symptoms [were] independently associated with suicidal risk,” the researchers found. Most adolescents with suicidal ideation or suicide attempt met criteria for at least one mental health problem.

“These findings suggest that suicide risk should be systematically assessed in adolescents who present with mental health symptoms and not solely in adolescents with clinically diagnosed mental disorders,” said Massimiliano Orri, PhD, and colleagues. Dr. Orri is affiliated with the McGill Group for Suicide Studies, Douglas Mental Health University Institute, Montreal, and the University of Bordeaux (France).

To document the prevalence of passive or serious suicidal ideation and suicide attempt from ages 13-20 years and examine correlations with mental health symptoms, Dr. Orri and colleagues analyzed data from 1,618 participants in the Quebec Longitudinal Study of Child Development. The population-based study follows individuals born in 1997 and 1998 in Quebec. Participants answered questions about suicidal ideation or suicide attempt in the past year at ages 13, 15, 17, or 20 years (“Did you ever think about suicide?” “Did you ever seriously think of attempting suicide?” and “How many times did you attempt suicide?”). The researchers assessed symptoms of mental health problems using self-report questionnaires.

Lifetime prevalence of suicide-related outcomes was higher for female participants than for male participants. The prevalence of passive suicidal ideation was 28% in females versus 15% in males. The prevalence of serious suicidal ideation was 12% in females versus 8% in males. The prevalence of suicide attempt was 9% in females versus 4% in males. “Sex differences in suicidal ideation and suicide attempt might be attributed to various factors, such as mental health (e.g., higher prevalence of depression in female participants) or social stigma (e.g., greater stigma around suicide in male than in female participants),” the authors wrote.

In the entire cohort, the prevalence of passive suicidal ideation increased from 12% at 13 years to 18% at 17 years. The prevalence of serious suicidal ideation increased from 3% at 13 years to 10% at 20 years. The prevalence of suicide attempt was approximately 4% at each age.

“Although having a major depressive episode is a well-known risk factor of suicidal ideation and suicide attempt, our study adds to the general body of knowledge by showing associations with suicide-related outcomes across the full spectrum of depressive symptoms,” Dr. Orri and colleagues wrote. “This suggests that youth who present with depressive symptoms (and not solely those who are clinically depressed) may be more likely to experience suicidal ideation or attempt suicide.”

The estimated rates of serious suicidal ideation and attempted suicide by age 20 years are consistent with previous U.S. and Canadian surveys. Sample attrition, the use of different questionnaires in early and late adolescence, and the lack of information about substance use and psychotic symptoms are among the study’s limitations.

Six of the authors were supported by grants from a variety of Canadian and European agencies and the American Foundation for Suicide Prevention. All of the authors said they had no relevant financial disclosures.

Combining a personalized cancer vaccine with an immune checkpoint inhibitor induced neoantigen-specific immune responses in most patients with advanced solid tumors in a phase 1b study.

Only two clinical responses were seen in this early investigation of the vaccine, RO7198457, combined with the PD-L1 inhibitor atezolizumab. However, T-cell responses were observed in about three-quarters of the patients evaluated, according to study investigator Juanita Lopez, MB BChir, PhD.

Those immune responses, coupled with preliminary evidence of infiltration of RO7198457-stimulated T cells into tumors, suggest the viability of this individualized anticancer strategy, according to Dr. Lopez, a consultant medical oncologist at The Royal Marsden NHS Foundation Trust and The Institute of Cancer Research, London.

“Failure of T-cell priming is a major cause of lack of response to immune checkpoint inhibitors,” Dr. Lopez said in an interview. “We hoped that, by eliciting a tumor-specific T-cell response, we would be able to overcome this.”

Preclinical data suggested the combination of vaccine and immune checkpoint inhibitors improved outcomes, which prompted the current study, added Dr. Lopez, who presented results from this study at the American Association for Cancer Research virtual meeting II.

Dr. Lopez noted that mutated neoantigens are recognized as foreign and have been shown to induce stronger T-cell responses, compared with shared antigens, likely because of a lack of central tolerance.

“Most of these mutated neoantigens are not shared between the patients, and therefore, targeted neoantigen-specific therapy requires an individualized approach,” she explained.

RO7198457 is manufactured on a per-patient basis and includes as many as 20 tumor-specific neoepitopes.
 

Study details

Dr. Lopez presented results from dose-escalation and expansion cohorts of the study, which included 142 patients with advanced solid tumors. The patients had colorectal, skin, kidney, lung, urothelial, breast, gynecologic, and head and neck cancers.

Most patients had low or no PD-L1 expression, and nearly 40% had received prior treatment with a checkpoint inhibitor.

Patients received nine doses of RO7198457 at 25-50 mcg during the 12-week induction stage. They then received RO7198457 every eight cycles until disease progression. Patients received atezolizumab at 1,200 mg on day 1 of each 21-day cycle.

Induction of proinflammatory cytokines was observed at each dose tested, and ex vivo T-cell responses were noted in 46 of 63 patients evaluated, or 73%.

T-cell receptors specific to RO7198457 were present posttreatment in a patient with rectal cancer, providing some preliminary evidence suggesting infiltration of RO7198457-stimulated T cells in the tumor, Dr. Lopez said.

There were two clinical responses. A patient with rectal cancer had a complete response, and a patient with triple-negative breast cancer had a partial response.

The combination of RO7198457 with atezolizumab was generally well tolerated, and the maximum tolerated dose was not reached, Dr. Lopez said. Most adverse events were grade 1/2, and immune-mediated adverse events were rare.
 

Implications and next steps

This study furthers earlier observations from neoantigen vaccine studies by linking dosing of the vaccine to dosing with immune checkpoint inhibitor, rather than giving the vaccine in the period leading up to immune checkpoint inhibitor administration, according to former AACR President Elaine R. Mardis, PhD, of Nationwide Children’s Hospital and The Ohio State University College of Medicine, both in Columbus.

That said, the implications for clinical practice remain unclear, according to Dr. Mardis.

“This combination did elicit an immune response that was highly specific for the neoantigen vaccine, but most patients did not receive a clinical benefit of disease response,” Dr. Mardis said in an interview. “This tells us the combination approach used was, overall, not quite right, and we need to continue to innovate in this area.”

The low clinical response rate in the study was likely caused in part by the fact that patients had very advanced disease and were heavily pretreated, according to Dr. Lopez

Randomized phase 2 studies of RO7198457 are now underway, Dr. Lopez said. One is a study of RO7198457 plus atezolizumab as adjuvant treatment for non–small cell lung cancer (NCT04267237). Another is testing RO7198457 in combination with pembrolizumab as first-line treatment for melanoma (NCT03815058).

The current study was funded by Genentech and BioNTech. Dr. Lopez reported disclosures related to Roche/Genentech, Basilea Pharmaceutica, and Genmab. Dr. Mardis reported disclosures related to Quiagen NV, PACT Pharma, Kiadis Pharma NV, and Interpreta.

Dual-energy computed tomography (DECT) appears to have limited utility for differentiating between gout and calcium pyrophosphate deposition disease (CPPD), according to a German prospective cohort study. Findings were reported at the annual European Congress of Rheumatology, held online this year because of COVID-19.

“Differentiation of gout and pseudogout, or CPPD, is sometimes difficult,” said presenting investigator Valentin S. Schäfer, MD, associate professor of internal medicine and head of the department of rheumatology and clinical immunology at University Hospital Bonn (Germany).

“Arthrocentesis and subsequent polarization microscopy remains the gold standard,” he noted. “Novel diagnostic approaches, such as DECT, have recently been validated for gout, but limited data [are] available on the use of DECT in patients with CPPD.”

The investigators studied 30 patients: 22 with suspected gout and 8 with suspected CPPD. All underwent arthrocentesis with subsequent polarization microscopy for definitive diagnosis, plus clinical examination, ultrasound examination, conventional radiography, DECT, and assessment of 12 laboratory parameters.

For diagnosis of gout, DECT had a sensitivity and specificity of 59.1% and 100%, respectively, Dr. Schäfer reported, noting that this sensitivity falls considerably short of the 90% previously reported for gout.

Corresponding sensitivity and specificity were 90.9% and 75% for ultrasound, 58.8% and 100% for conventional radiography, and 81.8% and 87.5% for the rheumatologists’ suspected clinical diagnosis.

For diagnosis of CPPD, DECT had sensitivity of 37.5% and specificity of 81.8%. Corresponding values were 87.5% and 91% for ultrasound, 0% and 94.1% for conventional radiography, and 75.0% and 100% for suspected clinical diagnosis.

None of the 12 laboratory parameters studied – uric acid, C-reactive protein, organic phosphate, and leukocytes, among others – significantly differentiated between conditions.

“Both ultrasound and suspected clinical diagnosis had higher sensitivities than DECT for gout and CPPD,” Dr. Schäfer concluded. “Further studies with larger patient cohorts and perhaps modified scan protocols are needed in order to determine the diagnostic utility of DECT in CPPD.”
 

Findings in context

“Noninvasive, accurate methods for distinguishing between gout and CPPD will improve clinical care,” Sara K. Tedeschi, MD, MPH, predicted in an interview.

“Arthrocentesis is painful in an acutely inflamed joint, can be difficult to perform on small joints, and is underutilized in clinical practice,” she elaborated. And ultrasound is operator dependent and does not quantify crystal volume in and around the joint.

The question addressed by the study is therefore clinically relevant, according to Dr. Tedeschi, a rheumatologist at Brigham and Women’s Hospital and assistant professor of medicine at Harvard Medical School, Boston.

However, among the patients with CPPD, the study did not report specific phenotypes (acute inflammatory arthritis, chronic inflammatory arthritis, and osteoarthritis with calcium pyrophosphate deposits), she noted. “It is difficult to draw conclusions about the sensitivity or specificity of DECT for CPPD without this information, especially among just 8 CPPD patients.”

In addition, among the patients with gout, the proportion having new-onset disease with flare duration less than 6 weeks and the proportion with tophi were unknown, both of which affected DECT sensitivity in the previous study that reported 90% sensitivity. “Based on the 95% confidence interval in the present study, it is possible that with a larger sample size, DECT sensitivity for gout would have been higher,” she pointed out. “We also do not know the DECT software settings, which impact DECT interpretation as positive or negative for the crystal of interest.”

Finally, “it would be relevant to know what joints were aspirated and imaged in each group,” Dr. Tedeschi said. “For example, if the first metatarsophalangeal (MTP) joint was aspirated and imaged for half of the gout patients but for none of the CPPD patients, that may affect the study interpretation.”

The study did not receive any specific funding. Dr. Schäfer disclosed a variety of financial relationships with multiple pharmaceutical companies. Dr. Tedeschi disclosed receiving grant support from the National Institutes of Health to study imaging modalities for CPPD, and being first author on a study comparing the sensitivity of DECT, ultrasound, and x-ray for acute CPP crystal arthritis.

“Differentiation of gout and pseudogout, or CPPD, is sometimes difficult,” said presenting investigator Valentin S. Schäfer, MD, associate professor of internal medicine and head of the department of rheumatology and clinical immunology at University Hospital Bonn (Germany).

“Arthrocentesis and subsequent polarization microscopy remains the gold standard,” he noted. “Novel diagnostic approaches, such as DECT, have recently been validated for gout, but limited data [are] available on the use of DECT in patients with CPPD.”

The investigators studied 30 patients: 22 with suspected gout and 8 with suspected CPPD. All underwent arthrocentesis with subsequent polarization microscopy for definitive diagnosis, plus clinical examination, ultrasound examination, conventional radiography, DECT, and assessment of 12 laboratory parameters.

For diagnosis of gout, DECT had a sensitivity and specificity of 59.1% and 100%, respectively, Dr. Schäfer reported, noting that this sensitivity falls considerably short of the 90% previously reported for gout.

Corresponding sensitivity and specificity were 90.9% and 75% for ultrasound, 58.8% and 100% for conventional radiography, and 81.8% and 87.5% for the rheumatologists’ suspected clinical diagnosis.

For diagnosis of CPPD, DECT had sensitivity of 37.5% and specificity of 81.8%. Corresponding values were 87.5% and 91% for ultrasound, 0% and 94.1% for conventional radiography, and 75.0% and 100% for suspected clinical diagnosis.

None of the 12 laboratory parameters studied – uric acid, C-reactive protein, organic phosphate, and leukocytes, among others – significantly differentiated between conditions.

“Both ultrasound and suspected clinical diagnosis had higher sensitivities than DECT for gout and CPPD,” Dr. Schäfer concluded. “Further studies with larger patient cohorts and perhaps modified scan protocols are needed in order to determine the diagnostic utility of DECT in CPPD.”
 

Findings in context

“Noninvasive, accurate methods for distinguishing between gout and CPPD will improve clinical care,” Sara K. Tedeschi, MD, MPH, predicted in an interview.

“Arthrocentesis is painful in an acutely inflamed joint, can be difficult to perform on small joints, and is underutilized in clinical practice,” she elaborated. And ultrasound is operator dependent and does not quantify crystal volume in and around the joint.

The question addressed by the study is therefore clinically relevant, according to Dr. Tedeschi, a rheumatologist at Brigham and Women’s Hospital and assistant professor of medicine at Harvard Medical School, Boston.

However, among the patients with CPPD, the study did not report specific phenotypes (acute inflammatory arthritis, chronic inflammatory arthritis, and osteoarthritis with calcium pyrophosphate deposits), she noted. “It is difficult to draw conclusions about the sensitivity or specificity of DECT for CPPD without this information, especially among just 8 CPPD patients.”

In addition, among the patients with gout, the proportion having new-onset disease with flare duration less than 6 weeks and the proportion with tophi were unknown, both of which affected DECT sensitivity in the previous study that reported 90% sensitivity. “Based on the 95% confidence interval in the present study, it is possible that with a larger sample size, DECT sensitivity for gout would have been higher,” she pointed out. “We also do not know the DECT software settings, which impact DECT interpretation as positive or negative for the crystal of interest.”

Finally, “it would be relevant to know what joints were aspirated and imaged in each group,” Dr. Tedeschi said. “For example, if the first metatarsophalangeal (MTP) joint was aspirated and imaged for half of the gout patients but for none of the CPPD patients, that may affect the study interpretation.”

The study did not receive any specific funding. Dr. Schäfer disclosed a variety of financial relationships with multiple pharmaceutical companies. Dr. Tedeschi disclosed receiving grant support from the National Institutes of Health to study imaging modalities for CPPD, and being first author on a study comparing the sensitivity of DECT, ultrasound, and x-ray for acute CPP crystal arthritis.

A pair of new vaccines for adults aged 65 years and older will be available for the 2020-2021 flu season – Fluzone high-dose quadrivalent, which replaces the trivalent Fluzone high-dose and Fluad quadrivalent (Seqirus), according to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices.

At a virtual meeting on June 24, the committee voted unanimously to approve the vaccine recommendations for annual influenza immunization of all individuals aged 6 months and older. They also voted to accept some guidance and language changes to the recommendations.

The past flu season was unique in its overlap with the emergence of the COVID-19 coronavirus, which likely contributed to a third peak in reported cases of influenza-like illness at approximately week 14 of last season, said Lisa Grohskopf, MD, of the CDC’s influenza division, who presented data on last year’s activity and the updates for next season.

The CDC estimates that 39,000,000-56,000,000 flu illnesses occurred in the United States from Oct. 1, 2019, to April 4, 2020, said Dr. Grohskopf. Estimates also suggest as many as 740,000 hospitalizations and 62,000 deaths related to the seasonal flu.

Preliminary results of vaccine effectiveness showed 39% overall for the 2019-2020 season, with more substantial protection against influenza B and lower protection against A/H1N1pmd09.

Vaccine safety data from the Vaccine Adverse Event Reporting System and Vaccine Safety Datalink showed no new safety concerns for any flu vaccine types used last year, Dr. Grohskopf noted.

Based on this information, three components (A/H1N1pdm09, A/H3N2, and B/Victoria) have been updated for the 2020-2021 vaccines, said Dr. Grohskopf. The egg-based influenza vaccines will include hemagglutinin derived from an A/Guangdong-Maonan/SWL1536/2019(H1N1)pdm09–like virus, an A/Hong Kong/2671/2019(H3N2)–like virus and a B/Washington/02/2019 (Victoria lineage)–like virus, and (for quadrivalent vaccines) a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

Nonegg vaccines will contain hemagglutinin derived from an A/Hawaii/70/2019 (H1N1)pdm09–like virus, an A/Hong Kong/45/2019 (H3N2)–like virus, a B/Washington/02/2019 (Victoria lineage)–like virus, and a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

New guidance for next year’s flu season includes a change to the language in the contraindications and precautions table to simply read “Contraindications,” with more details in the text explaining package insert contraindications and ACIP recommendations, Dr. Grohskopf said. In addition, updated guidance clarifies that live-attenuated influenza vaccine quadravalents (LAIV4) should not be used in patients with cochlear implants, active cerebrospinal fluid leaks, and anatomical or functional asplenia, based on ACIP’s review of the latest evidence and the availability of alternative vaccines.

ACIP also updated guidance on the use of antivirals and LAIV4. Based on half-lives, language was added indicating that clinicians should assume interference if antivirals are given within certain intervals of LAIV4, Dr. Grohskopf explained. “Newer antivirals peramivir and baloxavir have longer half-lives than oseltamivir and zanamivir, and insufficient data are available on the use of LAIV4 in the setting of antiviral use.”

The ACIP members had no financial conflicts to disclose.

To the Editor:

Raynaud phenomenon is characterized by vasospasm of arterioles causing intermittent ischemia of the digits. The characteristic triphasic color change presents first as a dramatic change in skin color from normal to white, as the vasoconstriction causes pallor secondary to ischemia. This change is followed by a blue appearance, as cyanosis results from the deoxygenated venous blood. Finally, reflex vasodilation and reperfusion manifest as a red color from erythema. Several cases have been reported describing Raynaud phenomenon affecting the nipples of breastfeeding women.^1-5 This vasospasm results in episodic nipple pain manifesting from breastfeeding and exposure to cold. If it is not appropriately treated, the pain’s severity causes affected women to stop breastfeeding. We report a case of vasospasm of the nipple in which the patient experienced nipple pain and a separate lancinating pain that radiated through the breasts.

A 36-year-old woman presented with excruciating nipple and breast pain 3 weeks after delivering her first child. She had no history of smoking or Raynaud phenomenon. The nipple pain was triggered upon breastfeeding and exposure to cold. During these episodes, the nipples would initially blanch white, then turn purple and finally a deep red. The patient also experienced an episodic excruciating lancinating pain of the breast that would randomly and spontaneously radiate through either breast several times per day for 15 to 30 seconds. A workup including an antinuclear antibody test, complete blood cell count with differential, and comprehensive metabolic panel all were within reference range.

The patient was diagnosed with nipple vasospasm. Partial relief of nipple pain occurred after treatment with 30 mg daily of nifedipine; 60 mg daily resulted in complete control, allowing the patient to breastfeed without discomfort, but the lancinating pain continued unabated. The patient could not discontinue breastfeeding because her child was intolerant to formula. She became despondent, as she could find no relief from the pain that she found to be intolerable. Because the patient’s description was reminiscent of the lancinating pain seen in postherpetic neuralgia, a trial of pregabalin was prescribed. A dosage of 75 mg twice daily resulted in near-complete resolution of the pain. After 3 months, the patient successfully weaned her child from breast milk to formula, and the nipple and breast pain promptly resolved. The baby experienced no adverse effects from the patient’s use of pregabalin.

This condition was first described by Gunther¹ in 1970 as initial blanching of the nipple followed by a mulberry color. It was termed psychosomatic sore nipples.¹ Lawlor-Smith and Lawlor-Smith² described the condition in 1997 and termed it vasospasm of the nipple. They reported 5 patients who experienced debilitating nipple pain as well as the triphasic color change of Raynaud phenomenon or a biphasic color change (white and blue). Two patients had a history of Raynaud phenomenon affecting the digits before their first pregnancy.² Anderson et al³ presented 12 breastfeeding women with Raynaud phenomenon of the nipple; only 1 patient had a history of Raynaud phenomenon. In this series, all 6 women who chose to try nifedipine responded well to the drug.³ 

Raynaud phenomenon of the nipple also has been reported to be associated with the use of labetalol.⁴ In this case, the patient had a history of Raynaud phenomenon affecting the toes and nipples on cold days. In 2 subsequent pregnancies she was treated with labetalol for pregnancy-induced hypertension, which resulted in severe nipple pain with each pregnancy unrelated to cold weather. Unlike other cases, this patient experienced antenatal symptoms in addition to the typical postnatal symptoms. The nipple pain resolved with discontinuation of the labetalol.⁴

Barrett et al⁵ conducted a retrospective review of medical records of 88 breastfeeding mothers who presented with nipple pain and dermatitis. They defined the criteria for Raynaud phenomenon of the nipple as chronic deep breast pain (in general lasting >4 weeks) that responded to therapy for the condition and had at least 2 of the following characteristics: (1) observed or self-reported color changes of the nipple, especially with cold exposure (white, blue, or red); (2) cold sensitivity or color changes of the hands or feet with cold exposure; or (3) failed therapy with oral antifungals. Using these criteria, they diagnosed 22 women (25%) with Raynaud phenomenon of the nipple; 20 (91%) reported a history of cold sensitivity or color change of acral surfaces. Of 12 patients who received and tolerated nifedipine use, 10 (83%) reported decreased pain or complete resolution. This series described breast or nipple pain, whereas other reported cases only described nipple pain. The authors described a sharp, shooting, or stabbing pain—qualifications not previously noted.⁵ Our patient experienced both nipple pain and a lancinating breast pain consistent with the cases reported by Barrett et al.⁵

The nipple pain and treatment response in our patient was typical of previously reported cases of vasospasm of the nipple in breastfeeding women; however, Barrett et al⁵ did not describe individual patients who exhibited the dual nature of the pain described in our patient. The nipple pain experienced during breastfeeding in our patient was successfully treated with nifedipine. We report the successful treatment of the separate lancinating pain with pregabalin.

Using these criteria, they diagnosed 22 women (25%) with Raynaud phenomenon of the nipple; 20 (91%) reported a history of cold sensitivity or color change of acral surfaces. Of 12 patients who received and tolerated nifedipine use, 10 (83%) reported decreased pain or complete resolution. This series described breast or nipple pain, whereas other reported cases only described nipple pain. The authors described a sharp, shooting, or stabbing pain—qualifications not previously noted.⁵ Our patient experienced both nipple pain and a lancinating breast pain consistent with the cases reported by Barrett et al.⁵

The nipple pain and treatment response in our patient was typical of previously reported cases of vasospasm of the nipple in breastfeeding women; however, Barrett et al⁵ did not describe individual patients who exhibited the dual nature of the pain described in our patient. The nipple pain experienced during breastfeeding in our patient was successfully treated with nifedipine. We report the successful treatment of the separate lancinating pain with pregabalin.
