As the lesion was growing, getting more violaceous and indurated, a biopsy was performed. The biopsy showed multiple discrete lobules of dermal capillaries with slight extension into the superficial subcutis. Capillary lobules demonstrate the “cannonball-like” architecture often associated with tufted angioma, and some lobules showed bulging into adjacent thin-walled vessels. Spindled endothelial cells lining slit-like vessels were present in the mid dermis, although this comprises a minority of the lesion. The majority of the subcutis was uninvolved. The findings are overall most consistent with a tufted angioma.

Kaposiform hemangioendothelioma (KHE) has been considered given the presence of occasional slit-like vascular spaces; however, the lesion is predominantly superficial and therefore the lesion is best classified as tufted angioma. GLUT–1 staining was negative.

At the time of biopsy, blood work was ordered, which showed a normal complete blood count with normal number of platelets, slightly elevated D-dimer, and slightly low fibrinogen. Several repeat blood counts and coagulation tests once a week for a few weeks revealed no changes.

The patient was started on aspirin at a dose of 5 mg/kg per day. After a week on the medication the lesion was starting to get smaller and less red.

Tufted angiomas are a rare type of vascular tumor within the spectrum of kaposiform hemangioendotheliomas. Most cases present within the first year of life; some occur at birth. They usually present as papules, plaques, or erythematous, violaceous indurated nodules on the face, neck, trunk, and extremities. The lesions can also be present with hyperhidrosis and hypertrichosis. Clinically, the lesions will have to be differentiated from other vascular tumors such as infantile hemangiomas, congenital hemangiomas, and Kaposi’s sarcoma, as well as subcutaneous fat necrosis of the newborn, cellulitis, and nonaccidental trauma.

Pathogenesis of tufted angiomas is poorly understood. A recent case report found a somatic mutation on GNA14.This protein regulates Ras activity and modulates endothelial cell permeability and migration in response to FGF2 and VEGFA. The p.205L mutation causes activation of GNA14, which upregulates pERK-MAPK pathway, suggesting MAPK inhibition as a potential target for therapy. Clinically, tufted angioma can present in three patterns: uncomplicated tufted angioma (most common type); tufted angioma without thrombocytopenia but with chronic coagulopathy, as it was seen in our patient; and tufted angioma associated with Kasabach-Merritt phenomenon (KMP). KMP is characterized by thrombocytopenia in association with microangiopathic hemolytic anemia, consumptive coagulopathy, and enlarging vascular tumor. Treatment of uncomplicated tufted angioma will depend on symptomatology, size, and location of the lesion. Smaller lesions in noncosmetically sensitive areas can be treated with surgical excision. Cases that are not amenable to excision can be treated with aspirin. There are also reports of response to topical modalities including tacrolimus and timolol. For complicated cases associated with KMP, sirolimus, systemic corticosteroids, ticlopidine, interferon, or vincristine are recommended. Some lesions may demonstrate spontaneous regression.

The photo distribution and annular quality of this patient’s rash, combined with his positive autoimmune work-up, led to a diagnosis of subacute cutaneous lupus erythematosus (SCLE), a nonscarring subtype of cutaneous lupus erythematosus.

SCLE is a chronic and relapsing condition that may manifest as either a papulosquamous or annular eruption.¹ It most commonly affects areas of sun exposure such as the shoulders, upper back, and extensor surfaces of the arms. This disorder typically affects young or middle-aged women between the ages of 30 and 40 years.

The differential diagnosis of this eruption includes dermatomyositis, polymorphous light eruption, psoriasis, tinea corporis, and other photodermatoses. The etiology of SCLE is multifactorial and may include a genetic susceptibility in combination with environmental triggers that provoke an autoimmune response to sunlight.¹ There is strong evidence linking drug-induced SCLE with proton pump inhibitors, anticonvulsants, beta-blockers, terbinafine, and immune modulators.²

As many as 70% of patients with SCLE have positive anti-Ro/SSA autoantibodies, and this is most often associated with Sjogren syndrome.¹ Interestingly, SCLE patients often exhibit symptoms that overlap with Sjogren syndrome. Systemic involvement is rare in SCLE, and if present, these symptoms are usually limited to arthritis and myalgia.

Treatment of SCLE includes photo-protective behaviors, topical corticosteroids/calcineurin inhibitors, and systemic therapies such as hydroxychloroquine (first-line), methotrexate, and mycophenolate mofetil (second-line).²

Our patient was started on hydroxychloroquine 200 mg orally bid, with complete resolution of the lesions at his 2 month–follow-up appointment. This case emphasizes the importance of distinguishing SCLE from other subtypes of lupus erythematosus as the prognostic course and treatment varies between these conditions.

The Food and Drug Administration has approved pembrolizumab (Keytruda) for the adjuvant treatment of stage IIB and IIC melanoma after complete resection in adults and children over age 12 years. The FDA also extended the approval to those with stage III disease.

The FDA approval on Dec. 3 was based on first interim findings from the randomized, placebo-controlled KEYNOTE-716 trial, which evaluated patients with stage IIB and IIC disease. 

Since the anti-PD-1 therapy was approved in metastatic melanoma 7 years ago, “we have built on this foundation in melanoma and have expanded the use of KEYTRUDA into earlier stages of this disease,” said Scot Ebbinghaus, MD, vice president, clinical research, Merck Research Laboratories, in a press release. “With today’s approval, we can now offer health care providers and patients 12 years and older the opportunity to help prevent melanoma recurrence with Keytruda across resected stage IIB, stage IIC, and stage III melanoma.”

In KEYNOTE-716, patients with completely resected stage IIB or IIC melanoma were randomly assigned to receive 200 mg of intravenous pembrolizumab, the pediatric dose 2 mg/kg (up to a maximum of 200 mg) every 3 weeks, or placebo for up to 1 year until disease recurrence or unacceptable toxicity.

After a median follow-up of 14.4 months, investigators reported a statistically significant 35% improvement in recurrence-free survival (RFS) in those treated with pembrolizumab, compared with those who received placebo (hazard ratio, 0.65).

The most common adverse reactions reported in patients receiving pembrolizumab in KEYNOTE-716 were fatigue, diarrhea, pruritus, and arthralgia, each occurring in at least 20% of patients.

“Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of Keytruda,” according to Merck.

Pinker or redder actinic keratoses (AKs) indicate greater inflammation, according to a retrospective study that analyzed images and histopathology slides of 49 actinic keratosis lesions.

Data suggest that up to 65% of squamous cell carcinomas (SCCs) were at some point diagnosed as AKs, wrote Jessica G. Labadie, MD, of the department of dermatology at Northwestern University, Chicago, and colleagues. Early identification of AKs is important to prevent progression to SCCs; previous studies have used histology or morphology, but not color, to characterize AK lesions, they said. In the study published in Dermatologic Surgery, the researchers analyzed images and histopathology slides to characterize AKs by color and to examine associations with inflammation and vasculature. They identified AKs from patients diagnosed between January 2018 and October 2019. The lesions were classified as white (4), brown (9), red (15), or pink (21).

Overall, white AKs had an absence of erythema and were significantly less likely to show inflammation on histopathology, compared with other colors. Brown AKs showed no significant increase in vascularity, but were significantly associated with pigment incontinence, basilar pigment presence, and absence of inflammation.

Notably, dermoscopy of red AKs revealed a distinctive polymorphous vessel pattern in most samples, as well as erythema in all. Similarly, all pink AKs showed erythema, and all showed inflammatory infiltrate on histology, although most did not show increased vascularity.

For all colors of AKs, there was a significant association between the presence of erythema on dermoscopy and the presence of inflammation on histology, while the absence of erythema on dermoscopy corresponded to a significant absence of inflammation on histology, the researchers noted.

“This report adds to the armamentarium of a dermatologist by proposing a novel way to characterize AK lesions,” the researchers wrote.

The study findings were limited by several factors including the inability to confirm which AKs would transform into SCCs based on color, and the inclusion of a study population with advanced AKs that may not generalize to typical AKs, the researchers noted. More research is needed to explore the impact of AK color on SCC development, they emphasized.

However, the results represent a novel way to characterize AK lesions, and triage them in a way that may spare some patients from unneeded biopsies, they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

An updated analysis of the phase 3 CheckMate 067 trial confirms the durability of combination immunotherapy for metastatic melanoma, representing a “substantial development” in treatment, researchers say.

Nearly half the patients treated with nivolumab (Opdivo) and ipilimumab (Yervoy) were alive at 6½ years. Within this group, 77% had not received further systemic treatment after coming off the study drugs.

After a minimum follow-up of 77 months, median overall survival was 72.1 months in patients on the combination, which was more than three times longer than the 19.9 months with ipilimumab alone (hazard ratio, 0.52; 95% confidence interval, 0.43-0.64) and twice as long as the 36.9 months with nivolumab alone (HR, 0.84; 95% CI, 0.67-1.04).

The results represent the longest median overall survival seen in a phase 3 trial of advanced melanoma and are evidence of “a substantial development in the melanoma treatment landscape versus the standard median survival of 8 months a decade ago,” researchers wrote in a study published online in the Journal of Clinical Oncology.

However, lead author Jedd D. Wolchok, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, noted that the study was not designed to compare nivolumab alone with the combination. “It wasn’t powered for that. [But] what we can say is that the highest survival was in the combination group,” Dr. Wolchok told this news organization.

Dr. Wolchok cautioned that the combination therapy is not currently standard of care. “PD-1 blockade – either nivolumab or the combination – are both excellent options for care,” he added. “I can’t tell you that one of them is the standard of care because that’s too complex of a decision.”

For example, he explained, “for a patient who only has lung metastases, a single-agent PD-1 blockade might be sufficient. But if it has spread to other organs, such as the liver or bones, which are more difficult to treat, that’s when we often reach for the combination.”

Other factors that weigh into the therapeutic decision are the patient’s performance status and their so-called clinical reserve for tolerating side effects. “The likelihood of having a high-grade side effect with the combination is more than twice that of the single agent,” Dr. Wolchok said.

Until 2011, only two therapies were approved for metastatic melanoma: Chemotherapy with dacarbazine and immunotherapy with high-dose interleukin-2, neither of which was very effective at prolonging life. But patient survival changed with the advent of targeted therapies and immunotherapy. Some patients are now living for years, and as the current study shows, many have surpassed the 5-year mark and are treatment free.

The updated CheckMate 067 analysis included patients with previously untreated, unresectable stage III/IV melanoma who were randomly assigned to receive nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks (four doses) followed by nivolumab 3 mg/kg every 2 weeks (n = 314), nivolumab 3 mg/kg every 2 weeks (n = 316), or ipilimumab 3 mg/ kg every 3 weeks (four doses; n = 315).

The authors reported the 5-year overall survival rates from the trial, published in the New England Journal of Medicine in 2019 – 52% with the combination, 44% with nivolumab alone, and 26% with ipilimumab alone.

In the updated study, overall survival at 6½ years had dropped slightly to 49%, 42%, and 23%, respectively. Patients with BRAF-mutant tumors had overall survival rates of 57%, 43%, and 25% versus 46%, 42%, and 22% in those with BRAF wild-type tumors.

Overall, median investigator-assessed progression-free survival was 11.5 months with the combination, 6.9 months with nivolumab alone, and 2.9 months with ipilimumab.

The new analysis also evaluated melanoma-specific survival (MSS), which removes competing causes of deaths from the long-term follow-up. The MSS was not reached in the combination group, and was 58.7 months in the nivolumab group and 21.9 months for ipilimumab, with MSS rates at 6.5 years of 56%, 48%, and 27%, respectively.

No new safety signals were detected, but there was more immune-mediated toxicity in the combination group, the researchers reported.

“The patients will continue to be followed,” said Dr. Wolchok, “And data are still being collected.”

An updated analysis of the phase 3 CheckMate 067 trial confirms the durability of combination immunotherapy for metastatic melanoma, representing a “substantial development” in treatment, researchers say.

Nearly half the patients treated with nivolumab (Opdivo) and ipilimumab (Yervoy) were alive at 6½ years. Within this group, 77% had not received further systemic treatment after coming off the study drugs.

After a minimum follow-up of 77 months, median overall survival was 72.1 months in patients on the combination, which was more than three times longer than the 19.9 months with ipilimumab alone (hazard ratio, 0.52; 95% confidence interval, 0.43-0.64) and twice as long as the 36.9 months with nivolumab alone (HR, 0.84; 95% CI, 0.67-1.04).

The results represent the longest median overall survival seen in a phase 3 trial of advanced melanoma and are evidence of “a substantial development in the melanoma treatment landscape versus the standard median survival of 8 months a decade ago,” researchers wrote in a study published online in the Journal of Clinical Oncology.

However, lead author Jedd D. Wolchok, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, noted that the study was not designed to compare nivolumab alone with the combination. “It wasn’t powered for that. [But] what we can say is that the highest survival was in the combination group,” Dr. Wolchok told this news organization.

Dr. Wolchok cautioned that the combination therapy is not currently standard of care. “PD-1 blockade – either nivolumab or the combination – are both excellent options for care,” he added. “I can’t tell you that one of them is the standard of care because that’s too complex of a decision.”

For example, he explained, “for a patient who only has lung metastases, a single-agent PD-1 blockade might be sufficient. But if it has spread to other organs, such as the liver or bones, which are more difficult to treat, that’s when we often reach for the combination.”

Other factors that weigh into the therapeutic decision are the patient’s performance status and their so-called clinical reserve for tolerating side effects. “The likelihood of having a high-grade side effect with the combination is more than twice that of the single agent,” Dr. Wolchok said.

Until 2011, only two therapies were approved for metastatic melanoma: Chemotherapy with dacarbazine and immunotherapy with high-dose interleukin-2, neither of which was very effective at prolonging life. But patient survival changed with the advent of targeted therapies and immunotherapy. Some patients are now living for years, and as the current study shows, many have surpassed the 5-year mark and are treatment free.

The updated CheckMate 067 analysis included patients with previously untreated, unresectable stage III/IV melanoma who were randomly assigned to receive nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks (four doses) followed by nivolumab 3 mg/kg every 2 weeks (n = 314), nivolumab 3 mg/kg every 2 weeks (n = 316), or ipilimumab 3 mg/ kg every 3 weeks (four doses; n = 315).

The authors reported the 5-year overall survival rates from the trial, published in the New England Journal of Medicine in 2019 – 52% with the combination, 44% with nivolumab alone, and 26% with ipilimumab alone.

In the updated study, overall survival at 6½ years had dropped slightly to 49%, 42%, and 23%, respectively. Patients with BRAF-mutant tumors had overall survival rates of 57%, 43%, and 25% versus 46%, 42%, and 22% in those with BRAF wild-type tumors.

Overall, median investigator-assessed progression-free survival was 11.5 months with the combination, 6.9 months with nivolumab alone, and 2.9 months with ipilimumab.

The new analysis also evaluated melanoma-specific survival (MSS), which removes competing causes of deaths from the long-term follow-up. The MSS was not reached in the combination group, and was 58.7 months in the nivolumab group and 21.9 months for ipilimumab, with MSS rates at 6.5 years of 56%, 48%, and 27%, respectively.

No new safety signals were detected, but there was more immune-mediated toxicity in the combination group, the researchers reported.

“The patients will continue to be followed,” said Dr. Wolchok, “And data are still being collected.”

The trial was supported by Bristol-Myers Squibb, the National Cancer Institute, and the National Institute for Health Research Royal Marsden–Institute of Cancer Research Biomedical Research Centre. Dr. Wolchok and coauthors reported relationships with Bristol-Myers Squibb and other drugmakers.

More clinical data suggesting that men may have a better response to immunotherapy than women in certain circumstances have been reported.

In a population-based cohort study, women with advanced melanoma and prior ipilimumab treatment who then received combination nivolumab and ipilimumab immunotherapy had a more than twofold increase in the risk for death in comparison with their male counterparts.

The hazard ratio (HR) for mortality among women versus men treated with the combination immunotherapy after prior ipilimumab treatment was 2.06 (P = .003). No such difference was observed among those receiving single-agent therapy with pembrolizumab or nivolumab (HR for mortality in women vs. men, 0.97; P = .85) or among patients without prior ipilimumab use (HR, 0.85; P = .16).

Women with prior ipilimumab use also had a nearly threefold increase in the risk for death with combination immunotherapy versus with single-agent anti–programmed cell death protein–1 (anti-PD-1) therapy (HR, 2.82), but no such difference was seen among the men in the study.

The findings were published online Dec. 2 in JAMA Network Open.

They come from an analysis of Surveillance, Epidemiology, and End Results (SEERS)–Medicare linked data for 982 men and 387 women with stage III or IV melanoma whose median age was 75 years.

The findings suggest that the patient’s sex should be considered in treatment planning to optimize outcomes, the authors noted.

“These novel findings suggest that, for women with a prior history of ipilimumab, treatment with anti-PD-1 therapy may be preferable to combination therapy, whereas for men, it is unclear which treatment is better,” they wrote.

In a press release, principal author Grace Lu-Yao, PhD, a professor at Thomas Jefferson University, Philadelphia, acknowledged that it remains unclear whether the increased risk for death in women is a result of treatment side effects or lack of efficacy, but she stressed that “this is a powerful signal in real-world data that we need to investigate further.

“This data is a wake-up call based on the experience of hundreds of patients on these drugs,” said Dr. Lu-Yao. “This real-world data demonstrates that the results derived from men might not be applicable to women and it is critical to design studies with sufficient power to evaluate treatment effectiveness by sex.”
 

Relevance for routine practice is unclear

The relevance of the findings for routine practice is unclear, given the median age of the cohort and a lack of data on whether excess mortality was cancer- or toxicity-related or due to another cause, Jeffrey S. Weber, MD, PhD, told this news organization. Dr. Weber is a professor and deputy director of the Laura and Isaac Perlmutter Cancer Center at New York University.

“The study is interesting and detailed, but it is a rather narrowly defined cohort that is over 65 and has a median of age 75, [which is] very different than most melanoma patient cohorts of patients treated with immunotherapy, whose median age is 10 years younger,” Dr. Weber said in an interview.

Furthermore, “in practice, almost no current patients will have been previously treated with ipilimumab and then receive combination immunotherapy,” he said. “Overall, these data would not impact on how I treat patients,” he said.
 

Gender differences in response

This study is not the first to show a gender-based difference in outcomes after immunotherapy. As previously reported by this news organization, a meta-analysis published in The Lancet Oncology in 2018 showed that immune checkpoint inhibitors are twice as effective as standard cancer therapies in men with advanced solid tumors, compared with their female counterparts.

However, sex-based differences remain under-assessed despite “accumulating evidence of the potential role played by sex in drug effectiveness owing to the biological differences between men and women,” wrote the authors of the latest study in melanoma.

“This lack of attention on the association of sex with the effectiveness of immune checkpoint inhibitor (ICI)–based immunotherapy may have significant negative consequences, especially because these treatments are associated with high toxicity and high treatment cost. For future trials, it would be crucial to examine effect modification by sex,” they added.

The study was funded by the Sidney Kimmel Cancer Center. Dr. Lu-Yao and coauthors have disclosed no relevant financial relationships. Dr. Weber is a regular contributor to Medscape. He reports relationships with Bristol-Myers Squibb, GlaxoSmithKline, Genentech BioOncology, Merck & Co, Novartis, EMD Serono, Celldex, CytomX, Nektar, Roche, Altor, Daiichi-Sankyo, and Eli Lilly and is named on patents filed for biomarkers for ipilimumab and nivolumab.

International consensus recommendations on the use of energy‐based devices (EBDs) for the treatment of acne scars, published in Lasers in Surgery and Medicine, call for EBDs to be used as first-line treatment.

Peter R. Shumaker, MD, a dermatologist and dermatologic surgeon at the VA San Diego Healthcare System and one of the authors of the paper, noted that a panel of 24 international experts in dermatology and plastic surgery assembled to develop the recommendations for integrating EBDs into the management of acne scarring.

“The advent of fractional laser technology in the mid-2000s ushered in an exciting new period of exploration and advances in scar treatment with EBDs,” Dr. Shumaker said in an interview. “Despite intense interest and a wealth of available literature, international treatment guidelines and patient access to these potentially life-changing treatments are currently lagging behind our capabilities.”

One of the key recommendations of the paper is that EBDs should have an expanded role in the treatment of acne scars, according to Dr. Shumaker, associate clinical professor of dermatology at the University of California, San Diego. “Panel members were unanimous in their view that EBDs, particularly ablative and nonablative fractional lasers, vascular lasers, and fractional radiofrequency devices, have an important role in the management of acne scars and should be considered a first-line treatment for a variety of scar types,” he said.

The process leading to the recommendations included developing clinical questions, based on input from the panelists and a literature review, and using a two-step modified Delphi method, “an iterative process used to achieve consensus for a defined clinical problem where there is little or conflicting published evidence and where expert opinion is decisive,” the authors wrote. This involved email questionnaires highlighting different topics, including the role of EBDs in mitigating and treating acne scars in patients with active acne, the use of different EBDs for treating different types of acne scars, and considerations in treating skin of color.

The panel noted considerations in the treatment of acne scars in skin of color. “Regardless of the platform, patients with darker skin types may require treatment modifications including: a reduction in fluence/pulse energy; decreased microcolumn density; greater intervals between treatments; longer pulse durations; epidermal cooling with fastidious technique to ensure appropriate cooling, additional cooling in between passes to decrease bulk heating; and pretreatment and posttreatment topical regimens (e.g., retinoids, bleaching creams, etc.) and strict sun precautions,” wrote the authors.

Panelists agreed that there is an absence of large, well-controlled, multicenter comparative trials of various laser and energy treatments for acne scars. “Such trials would be helpful in establishing the relative utility and persistence of benefit of various laser treatments and also in comparing their effectiveness versus that of nonenergy treatments,” the authors noted.

Asked to comment on the paper, Andrei Metelitsa, MD, a dermatologist in Calgary, Alta., and clinical associate professor at the University of Calgary, said the consensus recommendations on EBDs in acne scarring are “providing an international expert perspective, potentially changing a long-perceived paradigm of treatments.”

Dr. Metelitsa pointed out that the authors are taking a solid position with respect to reducing the delay to initiation of laser treatment following isotretinoin therapy. “The authors take a strong stance against the old dogma of postponing laser resurfacing for at least 6 months post isotretinoin,” he said. “According to the authors, there is sufficient evidence to support the idea of safely starting laser therapies, including fractional ablative and nonablative, within 1 month post isotretinoin, much sooner than previously suggested.”

He added that the authors point to the fact most experts utilize vascular lasers, such as pulsed-dye, to treat active acne in combination with medical therapy, thus reducing duration and severity of inflammation and potentially reducing further scar formation. “According to this published consensus, such laser therapies can even be used while the patient is actively treated with isotretinoin,” he said.

Dr. Metelitsa noted that the consensus recommendations outline how the choice of device should be guided by the clinical subtype of acne scars.

Dr. Shumaker, Dr. Metelitsa, and the authors have disclosed no relevant financial relationships.

Asked to comment on the paper, Andrei Metelitsa, MD, a dermatologist in Calgary, Alta., and clinical associate professor at the University of Calgary, said the consensus recommendations on EBDs in acne scarring are “providing an international expert perspective, potentially changing a long-perceived paradigm of treatments.”

Dr. Metelitsa pointed out that the authors are taking a solid position with respect to reducing the delay to initiation of laser treatment following isotretinoin therapy. “The authors take a strong stance against the old dogma of postponing laser resurfacing for at least 6 months post isotretinoin,” he said. “According to the authors, there is sufficient evidence to support the idea of safely starting laser therapies, including fractional ablative and nonablative, within 1 month post isotretinoin, much sooner than previously suggested.”

He added that the authors point to the fact most experts utilize vascular lasers, such as pulsed-dye, to treat active acne in combination with medical therapy, thus reducing duration and severity of inflammation and potentially reducing further scar formation. “According to this published consensus, such laser therapies can even be used while the patient is actively treated with isotretinoin,” he said.

Dr. Metelitsa noted that the consensus recommendations outline how the choice of device should be guided by the clinical subtype of acne scars.

Sublingual immunotherapy (SLIT) with house dust mite (HDM) extract showed some benefit in improving the signs and symptoms of atopic dermatitis in mite-sensitized patients, but improvement in the primary outcome was not significant, new data show.

Results of the small, randomized, double-blind, placebo-controlled trial were published recently in The Journal of Allergy and Clinical Immunology: In Practice.

Lead author Sarah Sella Langer, MD, of the department of medicine, Ribeirão Preto (Brazil) Medical School, University of São Paulo, and colleagues said their results suggest HDM SLIT is safe and effective as an add-on treatment.

The dust mite extract therapy had no major side effects after 18 months of treatment, the authors reported.

The researchers included data from 66 patients who completed the study. The participants were at least 3 years old, registered at least 15 on the SCORing Atopic Dermatitis (SCORAD) measure, and had a skin prick test and/or immunoglobulin E (IgE) test for sensitization to dust mites.

Patients were grouped by age (younger than 12 years or 12 years and older) to receive HDM SLIT (n = 35) or placebo (n = 31) 3 days a week for the study period – between May 2018 and June 2020 – at the Clinical Research Unit of Ribeirão Preto Medical School Hospital.

At baseline, the mean SCORAD was 46.9 (range, 17-87).

After 18 months, 74.2% and 58% of patients in HDM SLIT and placebo groups, respectively, showed at least a15-point decrease in SCORAD (relative risk, 1.28; 95% confidence interval, 0.89-1.83). However, those primary outcome results did not reach statistical significance.

On the other hand, some secondary outcomes did show significant results.

At 95% CI, the researchers reported significant objective-SCORAD decreases of 56.8% and 34.9% in HDM SLIT and placebo groups (average difference, 21.3). Significantly more patients had a score of 0 or 1 on the 5-point Investigator’s Global Assessment scale in the intervention group than in the placebo group (14/35 vs. 5/31; RR, 2.63).

There were no significant changes in the Eczema Area and Severity Index, the visual analogue scale for symptoms, the pruritus scale, or the Dermatology Life Quality Index.

Patients in the trial, most of whom had moderate to severe disease, continued to be treated with usual, individualized therapy for AD, in accordance with current guidelines and experts’ recommendations.

Tina Sindher, MD, an allergist with the Sean N. Parker Center for Allergy and Asthma Research at Stanford (Calif.) University, , told this news organization that the results are not robust enough to recommend the immunotherapy widely.

She pointed out that even in the placebo group, more than half the patients met the primary endpoint.

However, she did say HDM SLIT could be considered as an add-on treatment for the right patients, especially since risk for an allergic reaction or other adverse condition is small. The most common adverse effects were headache and abdominal pain, and they were reported in both the treatment and placebo groups.

With AD, she said, “there is no one drug that’s right for everyone,” because genetics and environment make the kind of symptoms and severity and duration different for each patient.

It all comes down to risk and benefits, she said.

She said if she had a patient with an environmental allergy who’s trying to manage nasal congestion and also happened to have eczema, “I think they’re a great candidate for sublingual dust mite therapy because then not only am I treating their nasal congestions, their other symptoms, it may also help their eczema,” Dr. Sindher said.

Without those concurrent conditions, she said, the benefits of dust mite immunotherapy would not outweigh the risks or the potential burden on the patient of having to take the SLIT.

She said she would present the choice to the patient, and if other treatments haven’t been successful and the patient wants to try it, she would be open to a trial period.

The study was supported by the Brazilian National Council for Scientific and Technological Development, the Institute of Investigation in Immunology, the National Institutes of Science and Technology, the Brazilian National Council for Scientific and Technological Development, and the São Paulo Research Foundation. The mite extract for immunotherapy was provided by the laboratory IPI-ASAC Brasil/ASAC Pharma Brasil. Dr. Langer received a doctoral scholarship from the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES). Dr. Sindher reported no relevant financial relationships.

Commentary by Lawrence F. Eichenfield, MD

Environmental triggers of atopic dermatitis (AD) may be difficult to assess, especially as children with AD commonly develop “overlap” conditions of allergic rhinitis, food allergy, and asthma. The place of immunotherapy in treatment of AD has been controversial over the years, with mixed results from studies on its effect on eczema in different subpopulations. However, a holistic view of allergy care makes consideration of environmental allergies reasonable. The study by Dr. Langer and colleagues was a well-designed double-blind placebo-controlled trial of house dust mite sublingual immunotherapy in mite-sensitized AD patients aged 3 and older with at least mild AD, though the mean eczema severity was severe. After 18 months, there was an impressive 74% decrease in eczema score (SCORAD), but also a 58% decrease in the placebo group. While the primary outcome measure wasn’t statistically significant, some secondary ones were. I agree with the commentary in the article that the data doesn’t support immunotherapy being advised to everyone, while its use as an add-on treatment for certain patients in whom the eczema may overlap with other allergic manifestations is reasonable. For several years at Rady Children’s Hospital, San Diego, we have run a multidisciplinary atopic dermatitis program where patients are comanaged by dermatology and allergy. We have learned to appreciate that a broad perspective on managing comorbid conditions in children with AD really helps the patients and families to understand the many effects of inflammatory and allergic conditions, with improved outcomes and quality of life.

As the pandemic shows no signs of ending, primary care doctors may be reassured that delivering care via video teleconferencing can be as effective as usual in-person consultation for several common health conditions.

This was a finding of a new study published in Annals of Internal Medicine involving a review of literature on video teleconferencing (VTC) visits, which was authored by Jordan Albritton, PhD, MPH and his colleagues.

The authors found generally comparable patient outcomes as well as no differences in health care use, patient satisfaction, and quality of life when visits conducted using VTC were compared with usual care.

While VTC may work best for monitoring patients with chronic conditions, it can also be effective for acute care, said Dr. Albritton, who is a research public health analyst at RTI International in Research Triangle Park, N.C., in an interview.

The investigators analyzed 20 randomized controlled trials of at least 50 patients and acceptable risk of bias in which VTC was used either for main or adjunct care delivery. Published from 2013 to 2019, these studies looked at care for diabetes and pain management, as well as some respiratory, neurologic, and cardiovascular conditions. Studies comparing VTC with usual care that did not involve any added in-person care were more likely to favor the VTC group, the investigators found.

“We excluded conditions such as substance use disorders, maternal care, and weight management for which there was sufficient prior evidence of the benefit of VTC,” Dr. Albritton said in an interview. “But I don’t think our results would have been substantially different if we had included these other diseases. We found general evidence in the literature that VTC is effective for a broader range of conditions.”

In some cases, such as if changes in a patient’s condition triggered an automatic virtual visit, the author said he thinks VTC may lead to even greater effectiveness.

“The doctor and patient could figure out on the spot what’s going on and perhaps change the medication,” Dr. Albritton explained.

In general agreement is Julia L. Frydman, MD, assistant professor in the Brookdale Department of Geriatric and Palliative Medicine at Icahn School of Medicine at Mount Sinai in New York, who was not involved in the RTI research.

“Telemedicine has promise across many medical subspecialties, and what we need now are more studies to understand the perspectives of patients, caregivers, and clinicians as well as the impact of telemedicine on health outcomes and healthcare utilization.”

In acknowledgment of their utility, video visits are on the rise in the United States. A 2020 survey found that 22% of patients and 80% of physicians reported having participated in a video visit, three times the rate of the previous year. The authors noted that policy changes enacted to support telehealth strategies during the pandemic are expected to remain in place, and although patients are returning to in-person care, the virtual visit market will likely continue growing.
 

Increased telemedicine use by older adults

“We’ve seen an exciting expansion of telemedicine use among older adults, and we need to focus on continuing to meet their needs,” Dr. Frydman said.

In a recent study of televisits during the pandemic, Dr. Frydman’s group found a fivefold greater uptake of remote consultations by seniors – from 5% to 25%. Although in-person visits were far more common among older adults.

A specific advantage of video-based over audio-only telehealth, noted Dr. Albritton, is that physicians can directly observe patients in their home environment. Sharing that view is Deepa Iyengar, MBBS/MD,MPH, professor of family medicine at McGovern Medical School at The University of Texas Health Science Center at Houston, where, she said, “the pandemic has put VTC use into overdrive.”

According to Dr. Iyengar, who was not involved in the RTI research, the video component definitely represents value-added over phone calls. “You can pick up visual cues on video that you might not see if the patient came in and you can see what the home environment is like – whether there are a lot of loose rugs on the floor or broken or missing light bulbs,” she said in an interview.
 

‘VTC is here to stay’

In other parts of the country, doctors are finding virtual care useful – and more common. “VTC is here to stay, for sure – the horse is out of the barn,” said Cheryl L. Wilkes, MD, an internist at Northwestern Medicine and assistant professor of medicine at Northwestern University in Chicago. “The RTI study shows no harm from VTC and also shows it may even improve clinical outcomes.”

Video visits can also save patients high parking fees at clinics and spare the sick or elderly from having to hire caregivers to bring them into the office or from having to walk blocks in dangerous weather conditions, she added. “And I can do a virtual visit on the fly or at night when a relative or caregiver is home from work to be there with the patient.”

In addition to being beneficial for following up with patients with chronic diseases such as hypertension or diabetes, VTC may be able to replace some visits that have traditionally required hands-on care, said Dr. Wilkes.

She said she knows a cardiologist who has refined a process whereby a patient – say, one who may have edema – is asked to perform a maneuver via VTC and then display the result to the doctor: The doctor says, “put your leg up and press on it hard for 10 seconds and then show me what it looks like,” according to Dr. Wilkes.

The key now is to identify the best persons across specialties from neurology to rheumatology to videotape ways they’ve created to help their patients participate virtually in consults traditionally done at the office, Dr. Wilkes noted.

But some conditions will always require palpation and the use of a stethoscope, according Dr. Iyengar.

“If someone has an ulcer, I have to be able to feel it,” she said.

And while some maternity care can be given virtually – for instance, if a mother-to be develops a bad cold – hands-on obstetrical care to check the position and health of the baby obviously has to be done in person. “So VTC is definitely going to be a welcome addition but not a replacement,” Dr. Iyengar said.

Gaps in research on VTC visits

Many questions remain regarding the overall usefulness of VTC visits for certain patient groups, according to the authors.

They highlighted, for example, the dearth of data on subgroups or on underserved and vulnerable populations, with no head-to-head studies identified in their review. In addition, they found no studies examining VTC versus usual care for patients with concurrent conditions or on its effect on health equity and disparities.

“It’s now our job to understand the ongoing barriers to telemedicine access, including the digital divide and the usability of telemedicine platforms, and design interventions that overcome them,” Dr. Frydman said. “At the same time, we need to make sure we’re understanding and respecting the preferences of older adults in terms of how they access health care.”

This study was supported by the Patient-Centered Outcomes Research Institute (PCORI). Dr. Albritton is employed by RTI International, the contractor responsible for conducting the research and developing the manuscript. Several coauthors disclosed support from or contracts with PCORI. One coauthor’s spouse holds stock in private health companies. Dr. Frydman, Dr. Iyengar, and Dr. Wilkes disclosed no competing interests relevant to their comments.

In addition, they found no studies examining VTC versus usual care for patients with concurrent conditions or on its effect on health equity and disparities.

“It’s now our job to understand the ongoing barriers to telemedicine access, including the digital divide and the usability of telemedicine platforms, and design interventions that overcome them,” Dr. Frydman said. “At the same time, we need to make sure we’re understanding and respecting the preferences of older adults in terms of how they access health care.”

This study was supported by the Patient-Centered Outcomes Research Institute (PCORI). Dr. Albritton is employed by RTI International, the contractor responsible for conducting the research and developing the manuscript. Several coauthors disclosed support from or contracts with PCORI. One coauthor’s spouse holds stock in private health companies. Dr. Frydman, Dr. Iyengar, and Dr. Wilkes disclosed no competing interests relevant to their comments.

As the pandemic shows no signs of ending, primary care doctors may be reassured that delivering care via video teleconferencing can be as effective as usual in-person consultation for several common health conditions.

This was a finding of a new study published in Annals of Internal Medicine involving a review of literature on video teleconferencing (VTC) visits, which was authored by Jordan Albritton, PhD, MPH and his colleagues.

The authors found generally comparable patient outcomes as well as no differences in health care use, patient satisfaction, and quality of life when visits conducted using VTC were compared with usual care.

While VTC may work best for monitoring patients with chronic conditions, it can also be effective for acute care, said Dr. Albritton, who is a research public health analyst at RTI International in Research Triangle Park, N.C., in an interview.

The investigators analyzed 20 randomized controlled trials of at least 50 patients and acceptable risk of bias in which VTC was used either for main or adjunct care delivery. Published from 2013 to 2019, these studies looked at care for diabetes and pain management, as well as some respiratory, neurologic, and cardiovascular conditions. Studies comparing VTC with usual care that did not involve any added in-person care were more likely to favor the VTC group, the investigators found.

“We excluded conditions such as substance use disorders, maternal care, and weight management for which there was sufficient prior evidence of the benefit of VTC,” Dr. Albritton said in an interview. “But I don’t think our results would have been substantially different if we had included these other diseases. We found general evidence in the literature that VTC is effective for a broader range of conditions.”

In some cases, such as if changes in a patient’s condition triggered an automatic virtual visit, the author said he thinks VTC may lead to even greater effectiveness.

“The doctor and patient could figure out on the spot what’s going on and perhaps change the medication,” Dr. Albritton explained.

In general agreement is Julia L. Frydman, MD, assistant professor in the Brookdale Department of Geriatric and Palliative Medicine at Icahn School of Medicine at Mount Sinai in New York, who was not involved in the RTI research.

“Telemedicine has promise across many medical subspecialties, and what we need now are more studies to understand the perspectives of patients, caregivers, and clinicians as well as the impact of telemedicine on health outcomes and healthcare utilization.”

In acknowledgment of their utility, video visits are on the rise in the United States. A 2020 survey found that 22% of patients and 80% of physicians reported having participated in a video visit, three times the rate of the previous year. The authors noted that policy changes enacted to support telehealth strategies during the pandemic are expected to remain in place, and although patients are returning to in-person care, the virtual visit market will likely continue growing.
 

Increased telemedicine use by older adults

“We’ve seen an exciting expansion of telemedicine use among older adults, and we need to focus on continuing to meet their needs,” Dr. Frydman said.

In a recent study of televisits during the pandemic, Dr. Frydman’s group found a fivefold greater uptake of remote consultations by seniors – from 5% to 25%. Although in-person visits were far more common among older adults.

A specific advantage of video-based over audio-only telehealth, noted Dr. Albritton, is that physicians can directly observe patients in their home environment. Sharing that view is Deepa Iyengar, MBBS/MD,MPH, professor of family medicine at McGovern Medical School at The University of Texas Health Science Center at Houston, where, she said, “the pandemic has put VTC use into overdrive.”

According to Dr. Iyengar, who was not involved in the RTI research, the video component definitely represents value-added over phone calls. “You can pick up visual cues on video that you might not see if the patient came in and you can see what the home environment is like – whether there are a lot of loose rugs on the floor or broken or missing light bulbs,” she said in an interview.
 

‘VTC is here to stay’

In other parts of the country, doctors are finding virtual care useful – and more common. “VTC is here to stay, for sure – the horse is out of the barn,” said Cheryl L. Wilkes, MD, an internist at Northwestern Medicine and assistant professor of medicine at Northwestern University in Chicago. “The RTI study shows no harm from VTC and also shows it may even improve clinical outcomes.”

Video visits can also save patients high parking fees at clinics and spare the sick or elderly from having to hire caregivers to bring them into the office or from having to walk blocks in dangerous weather conditions, she added. “And I can do a virtual visit on the fly or at night when a relative or caregiver is home from work to be there with the patient.”

In addition to being beneficial for following up with patients with chronic diseases such as hypertension or diabetes, VTC may be able to replace some visits that have traditionally required hands-on care, said Dr. Wilkes.

She said she knows a cardiologist who has refined a process whereby a patient – say, one who may have edema – is asked to perform a maneuver via VTC and then display the result to the doctor: The doctor says, “put your leg up and press on it hard for 10 seconds and then show me what it looks like,” according to Dr. Wilkes.

The key now is to identify the best persons across specialties from neurology to rheumatology to videotape ways they’ve created to help their patients participate virtually in consults traditionally done at the office, Dr. Wilkes noted.

But some conditions will always require palpation and the use of a stethoscope, according Dr. Iyengar.

“If someone has an ulcer, I have to be able to feel it,” she said.

And while some maternity care can be given virtually – for instance, if a mother-to be develops a bad cold – hands-on obstetrical care to check the position and health of the baby obviously has to be done in person. “So VTC is definitely going to be a welcome addition but not a replacement,” Dr. Iyengar said.

ANSWER

The correct answer is bullous impetigo (choice “a”).

Had the source of the problem been MRSA (choice “b”), there would have been marked tenderness and swelling. Psoriasis vulgaris (choice “c”) was a possibility; however, it almost never manifests with blisters, it rarely comes on as quickly as this patient’s problem did, and it produces scale that is far thicker and more tenacious than that seen in bullous impetigo. Nummular eczema (choice “d”) does not manifest with blisters and would likely have caused itching.

DISCUSSION

Impetigo is one of many common skin diseases—other examples include granuloma annulare and lichen planus—that have bullous variants, which can make diagnosis challenging. Impetigo is easy to diagnose in its more common papulosquamous form. But it also can manifest with flaccid blisters that last only a short time, leaving the round, scaly lesions seen in this case.

Staphylococcus aureus, the organism responsible for bullous impetigo, elaborates serine proteases, which bind to and cleave desmoglein-1. This effectively destroys the connections between skin layers, creating a space that is quickly filled with serum. The level of this separation is typically subcorneal, which allows the formation of a very thin, friable roof for the bulla.

This modern version of impetigo is not considered dangerous, despite its association with staph aureus. In pre-antibiotic times, the predominant organism was streptococcal, some types of which could be nephritogenic—that is, capable of causing Bright disease or, as it is now known, acute post-streptococcal glomerulonephritis. Fortunately, this potentially fatal condition is only rarely seen in modern times.

Two items of note about this case: Bullous impetigo, contrary to what was seen in this patient, typically favors intertriginous areas. And a key factor is the history of atopy, which renders the patient more susceptible to skin infections of all kinds.

Treatment

The patient responded well to topical mupirocin ointment, applied three times a day. In rare instances, impetigo can require an oral antibiotic, such as cephalexin.
