RESUMO
BACKGROUND: New highly effective drugs for moderate-to-severe cutaneous psoriasis are regularly marketed, and the hierarchy of treatments thus requires frequent review. OBJECTIVES: A Delphi method was used to enable a structured expert consensus on the use of systemic treatments and phototherapy among adults with moderate-to-severe psoriasis. METHODS: The Delphi method consists in achieving a convergence of opinions among a panel of experts using several rounds of questionnaires with controlled feedback between rounds. A two-part Delphi questionnaire was administered online to French psoriasis experts. In the first part, 180 items related to the prescription of systemic treatments and phototherapy for adult patients with moderate-to-severe psoriasis were grouped into 21 sections covering different lines of treatment and different forms of cutaneous psoriasis. The experts voted on each proposal using an ordinal 7-point Likert scale. The second part comprised 11 open-ended questions about special indications for each therapeutic class. These were converted into 101 questions for subsequent rounds. Consensus was deemed to have been reached if more than 80% of the experts agreed with a given proposal. RESULTS: Three rounds of questionnaires were sequentially sent to 35 participants between November 2021 and March 2022. Thirty-three (94%) completed all three rounds. For plaque psoriasis, only methotrexate was recommended by the experts as first-line systemic treatment (89% of votes). Cyclosporin was advocated in pustular and erythrodermic psoriasis, and acitretin was suggested for hyperkeratotic and palmoplantar psoriasis. In the event of failure of or intolerance to non-biological systemic treatments, guselkumab, risankizumab, ixekizumab or secukinumab were recommended by more than 80% of the experts. Tumor Necrosis Factor (TNF) inhibitors remain useful for patients with cardiovascular risk factors. Special indications were provided for each therapeutic class (methotrexate/narrowband ultraviolet B phototherapy, psoralen/ultraviolet A phototherapy, cyclosporin, acitretin, apremilast, TNF inhibitors, interleukin (IL)-12/23 inhibitors, IL-17(R)A inhibitors, and IL-23 inhibitors). CONCLUSIONS: This expert consensus statement indicate that newly available IL-17 and IL-23 inhibitors may be favored over TNF and IL-12/23 inhibitors as first-line biologics. The Centre of Evidence of the French Society of Dermatology has drawn up a decision-making algorithm to guide clinicians in the therapeutic management of moderate-to-severe psoriasis.
RESUMO
BACKGROUND: Strategies for the control of scabies should be adapted to local settings. Traditional communities in French Guiana have non-Western conceptions of disease and health. OBJECTIVES: The objectives for this study were to explore knowledge, attitudes and practices to identify potential factors associated with the failure of scabies treatment in these communities. METHODS: Patients with a clinical diagnosis of scabies, seen at either the Cayenne Hospital or one of 13 health centres between 01 April 2021 and 31 August 2021, were included as participants, and were seen again after 6 weeks to check for persistence of lesions. Factors associated with treatment failure were looked for both at inclusion and at 6 weeks. Semi-structured interviews were conducted with a diversified subsample of participants. RESULTS: In total, 164 participants were included in the quantitative component, and 21 were interviewed for the qualitative component. Declaring that the second treatment dose had been taken was associated with therapeutic success. Western treatments were not always affordable. Better adherence was observed with topical treatments than with oral ivermectin, whereas permethrin monotherapy was associated with failure. Scabies-associated stigma was high among Amerindians and Haitians but absent in Ndjuka Maroons. Participants reported environmental disinfection as being very complex. CONCLUSIONS: The treatment of scabies in traditional Guianan communities may vary depending on local perceptions of galenic formulations, disease-associated stigma and differences in access to health care. These factors should be taken into account when devising strategies for the control of scabies aimed at traditional communities living in remote areas, and migrant populations.

BACKGROUND: The nature of the COVID-19 pandemic led to concerns among patients and physicians about the potential impact of immunosuppressive treatments for chronic diseases such as psoriasis on the risk of severe COVID-19. OBJECTIVES: To describe treatment modifications and determine the incidence of COVID-19 infection among psoriasis patients during the first wave of the pandemic, and identify the factors associated with these events. METHODS: Data from PSOBIOTEQ cohort relating to the first COVID-19 wave in France (March to June, 2020), as well as a patient-centred COVID-19 questionnaire, were used to evaluate the impact of lockdown on changes (discontinuations, delays or reductions) in systemic therapies, and to determine the incidence of COVID-19 cases among these patients. Logistic regression models were used to assess associated factors. RESULTS: Among the 1751 respondents (89.3%), 282 patients (16.9%) changed their systemic treatment for psoriasis, with 46.0% of these changes being initiated by the patients themselves. Patients were more likely to experience psoriasis flare-ups during the first wave if they changed their treatment during this period (58.7% vs 14.4%; Pâ¯<â¯0.0001). Changes to systemic therapies were less frequent among patients with cardiovascular diseases (Pâ¯<â¯0.001), and those agedâ¯≥â¯65â¯years (Pâ¯=â¯0.02). Overall, 45 patients (2.9%) reported having COVID-19, and eight (17.8%) required hospitalization. Risk factors for COVID-19 infection were close contact with a positive case (Pâ¯<â¯0.001) and living in a region with a high incidence of COVID-19 (Pâ¯<â¯0.001). Factors associated with a lower risk of COVID-19 were avoiding seeing a physician (Pâ¯=â¯0.002), systematically wearing a mask during outings (Pâ¯=â¯0.011) and being a current smoker (Pâ¯=â¯0.046). CONCLUSIONS: Discontinuation of systemic psoriasis treatments during the first COVID-19 wave (16.9%) - mainly decided by patients themselves (46.0%) - was associated with a higher incidence of disease flares (58.7% vs 14.4%). This observation and factors associated with a higher risk of COVID-19 highlight the need to maintain and adapt patient-physician communication during health crises according to patient profiles, with the aim of avoiding unnecessary treatment discontinuations and ensuring that patients are informed about the risk of infection and the importance of complying with hygiene rules.

BACKGROUND: Biologics are the cornerstone of treatment of patients with moderate-to-severe plaque psoriasis and switches between biologics are frequently needed to maintain clinical improvement over time. OBJECTIVES: The main purpose of this study was to describe precisely switches between biologics and how their pattern changed over time with the recent availability of new biologic agents. METHODS: We included patients receiving a first biologic agent in the Psobioteq multicenter cohort of adults with moderate-to-severe psoriasis receiving systemic treatment. We described switches between biologics with chronograms, Sankey and Sunburst diagrams, assessed cumulative incidence of first switch by competing risks survival analysis and reasons for switching. We assessed the factors associated with the type of switch (intra-class - i.e. within the same therapeutic class - vs. inter-class) in patients switching from a TNF-alpha inhibitor using multivariate logistic regression. RESULTS: A total of 2153 patients was included. The cumulative incidence of switches from first biologic was 34% at 3 years. Adalimumab and ustekinumab were the most prescribed biologic agents as first and second lines of treatment. The main reason for switching was loss of efficacy (72%), followed by adverse events (11%). Patients receiving a TNF-alpha inhibitor before 2016 mostly switched to ustekinumab, whereas those switching in 2016 or after mostly switched to an IL-17 inhibitor. Patients switching from a first-line TNF-alpha inhibitor before 2016 were more likely to switch to another TNF-alpha inhibitor compared with patients switching since 2018. Patients switching from etanercept were more likely to receive another TNF-alpha inhibitor rather than another therapeutic class of bDMARD compared with patients switching from adalimumab. CONCLUSION: This study described the switching patterns of biologic treatments and showed how they changed over time, due to the availability of the new biologic agents primarily IL-17 inhibitors.

BACKGROUND: During isotretinoin treatment, special attention is required to detect any symptom or change in the mental health of patients. The monitoring is complex for adolescents because of confounding factors such as mood changes associated with adolescence and puberty and the higher psychosocial impairment due to the acne itself. AIM: To determine the utility of the Adolescent Depression Rating Scale (ADRS) for monitoring symptoms in adolescents before and during isotretinoin treatment in dermatology real-life practice. METHODS: This was a national, multicentre prospective study that enrolled a random sample of dermatologists treating adolescents. An algorithm including ADRS score and its changes between consecutive visits was used. At each visit, dermatologists rated their satisfaction with ADRS and its ease of use, while patients rated the acceptability of the ADRS. RESULTS: In total, 70 dermatologists used the algorithm for 1227 visits of 283 adolescents receiving isotretinoin. Of these 70 dermatologists, 80.8% were satisfied/very satisfied with the ADRS, 82.7% considered the use of the ADRS in clinical practice to be easy/very easy and 75% considered that the ADRS enabled them to discuss more easily the risk of depression with their patients. For the patients, acceptability of the ADRS was considered good by 93.8%. CONCLUSIONS: The implementation of the ADRS could be valuable in dermatology practice, optimizing the monitoring of patients and the good use of isotretinoin.

BACKGROUND: Eosinophilic annular erythema (EAE) is a rare eosinophil-related skin disease which typically manifests with annular erythematous plaques and severe pruritus. Besides the diagnosis, the treatment of EAE is challenging since relevant published data are sparse. METHODS: The aim of this study was to assess the underlying diseases, treatments and outcomes of patients with EAE. To this end, we conducted a retrospective multicenter study and a systematic review of the MEDLINE database. RESULTS: We included 18 patients with EAE followed in 8 centers. The MEDLINE database search yielded 37 relevant publications reporting 55 cases of EAE with 106 treatment sequences. The most common and efficient treatments included topical or systemic corticosteroids, hydroxychloroquine and dapsone. In refractory patients, a combination of systemic corticosteroids with hydroxychloroquine was associated with 88% of complete clinical response. DISCUSSION: To improve the management of EAE patients, we discuss the following treatment strategy: in topical steroid-resistant patients, hydroxychloroquine can be given as first-line systemic treatment. Dapsone, hydroxychloroquine or systemic corticosteroids are second-line options to consider. Last, monoclonal antibodies or JAK inhibitors targeting type 2 inflammation could represent promising last-resort options in refractory patients.

The classification of pityriasis lichenoides (PL) into pityriasis lichenoides et varioliformis acuta (PLEVA), PL chronica (PLC) and febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is based on both clinical and chronological features. In this retrospective monocentric study, we aimed to investigate the relevance of the classification in routine practice. We enrolled 49 patients (25 female, 24 male; median age 41 years). The lesions were papular in 76% of patients, necrotic in 12% and mixed in 12%. We found three histological patterns: 'classic' (65%), 'lymphomatoid' (13%) and 'mild' (22%). The 'lymphomatoid' pattern was associated with necrotic presentation and the 'mild' pattern with papular lesions (P = 0.01). Among the 27 patients with follow-up, 18% had relapses and 44% had chronic disease. One patient had mycosis fungoides. Neither clinical nor histological findings were correlated with disease progression, and are a reflection of the intensity of epidermal injury rather than of the disease course. The term 'pityriasis lichenoides' should be preferred to the classic PLEVA/PLC/FUMHD classification.

Frequently described as 'the worst itch' one can ever experience scabies itch is the hallmark of Sarcoptes scabiei mite infestation. Notably, the itchiness often persists for weeks despite scabicides therapy. The mechanism of scabies itch is not yet fully understood, and effective treatment modalities are still missing which can severely affect the quality of life. The aim of this review is to provide an overview of the scope of itch in scabies and highlight candidate mechanisms underlying this itch. We herein discuss scabies itch, with a focus on the nature, candidate underlying mechanisms and treatment options. We also synthesize this information with current understanding of the mechanisms contributing to non-histaminergic itch in other conditions. Itch is a major problem in scabies and can lead to grave consequences. We provide the latest insights on host-mite interaction, secondary microbial infection and neural sensitization with special emphasis on keratinocytes and mast cells to better understand the mechanism of itch in scabies. Also, the most relevant current modalities remaining under investigation that possess promising perspectives for scabies itch (i.e. protease-activated receptor-2 (PAR-2) inhibitor, Mas-related G protein-coupled receptor X2 (MRGPRX2) antagonist) are discussed. Greater understanding of these diverse mechanisms may provide a rational basis for the development of improved and targeted approaches to control itch in individuals with scabies.

BACKGROUND: There is no consensus on the treatment of drug reaction with eosinophilia and systemic symptoms (DRESS). At our center, systemic steroids (SS) are used for severe cases while topical steroids (TS) are used for mild and moderate forms. OBJECTIVES: To investigate the short-term outcome for patients with DRESS receiving SS as first-line therapy before being transferred to our department and then switched to TS after admission. METHODS: A retrospective monocenter study in DRESS patients (RegiSCAR score≥4) transferred to our dermatology department from a different setting between 07/2012 and 06/2018 and who had received SS before being transferred. Epidemiological, clinical and laboratory data were collected, as well as details of treatment modalities and outcome. RESULTS: Twenty patients were included. On admission to our department, 4 were assessed as having severe DRESS and continued on SS, while 16 were assessed as mild/moderate DRESS and were switched to TS. Among these 16 patients, the outcome on TS was favorable for 12 and quickly unfavorable for 4, who had to be switched back to SS. Retrospective analysis of the initial data (before transfer) showed that these 4 patients had previously had a greater number of severity criteria than the other 12. CONCLUSION: Caution is needed not only when deciding to initiate SS in DRESS but also on withdrawal of these drugs. Our series suggests that when SS are used as first-line therapy in DRESS patients with initial severity criteria, they should not be withdrawn quickly for a switch to TS, even where progression appears favorable, due to the risk of relapse.
