Background: Patients with atopic dermatitis (AD) may discontinue dupilumab owing to dupilumab-induced ocular adverse events (DOAEs) or dupilumab-induced facial redness (DFR).

Objective: To evaluate DOAE and DFR outcomes after switching to tralokinumab or Janus kinase inhibitor (JAKi).

Methods: This retrospective study included 106 patients discontinuing dupilumab because of DOAEs and/or DFR.

SETD2 is known to be the unique histone methyltransferase responsible for the trimethylation of the lysine 36 of histone H3 thus generating H3K36me3. This epigenetic mark is critical for transcriptional activation and elongation, DNA repair, mRNA splicing, and DNA methylation. Recurrent SETD2-inactivating mutations and altered H3K36me3 levels are found in cancer at high frequency and numerous studies indicate that SETD2 acts as a tumor suppressor.

Objectives: To investigate factors associated with dermatomyositis (DM) complete clinical response and overall survival with a focus on the use of immunosuppressive therapies in patients with cancer-associated DM.

Methods: We performed a multicentre, retrospective cohort study. Multivariable survival analyses used a Cox model with time-dependent covariates and adjustments with inverse probability censoring weighting.

Background: The effects of hyperbaric oxygen therapy (HBOT) on wound healing have been demonstrated mainly in diabetic foot ulcer.

Objectives: To study the efficacy and safety of HBOT in chronic painful wounds, excluding diabetic foot ulcers.

Methods: From 2008 to 2021, patients with chronic wounds showing no clinical improvement for more than 1 month, who were in pain despite the use of level 2 or 3 analgesics, and who had undergone HBOT sessions, were included in a monocentric retrospective study.

Article Synopsis
  • Systemic sclerosis (SSc) is a rare autoimmune disease classified into two groups based on skin involvement; this study investigates the role of autoantibody profiles in predicting organ damage and mortality compared to skin phenotype.
  • Researchers analyzed data from 1,605 patients across seven French hospitals, focusing on autoantibodies and their correlation with various organ issues and death rates.
  • Findings reveal that specific autoantibodies are strongly linked to serious complications like interstitial lung disease and renal crisis, while skin phenotype alone does not effectively predict patient outcomes.

Background: T-follicular-helper (Tfh) cells form a distinct population of T-helper cells with different polarizations (type 1, type 2 and type 17) that regulates humoral responses and may participate in the pathophysiology of B-cell mediated autoimmune diseases, such as bullous pemphigoid (BP), a dermatosis mediated by auto-antibodies specific for hemidesmosomal proteins.

Objectives: The aim was to evaluate the impact of superpotent topical corticosteroid (TCS) treatment, which is more effective and safer than high doses of oral corticosteroids and recommended first-line treatment of BP, on circulating Tfh cells.

Methods: We compared by flow cytometry the frequency, polarization and activation of blood Tfh cells from patients with BP at baseline and longitudinally after initiation of TCS treatment to age- and sex-matched healthy subjects.

In patients with moderate to severe atopic dermatitis (AD) showing an inadequate response to dupilumab 300mg/2weeks, few real-life studies reported the response to alternative regimen maintaining dupilumab. To assess and analyze the response to an increased dose of dupilumab or its combination with cyclosporin A (CsA), methotrexate (MTX), or itraconazole (ITRA), all adult AD patients from 7 French University Hospitals were retrospectively included if they achieved an inadequate response to dupilumab 300mg/2weeks and were subsequently treated with an increased dose of dupilumab (300mg every 7 or 10 days), or a combination of dupilumab 300mg/2weeks with CsA, MTX or ITRA. The response after 3 months, along with epidemiological, clinical, and therapeutic baseline characteristics, were collected.

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.

Article Synopsis
  • Sézary syndrome is a rare and deadly skin cancer, and this study looked into the survival rates and factors affecting outcomes, particularly focusing on the treatment mogamulizumab.
  • *The research analyzed data from 339 patients diagnosed between 2000 and 2020 across Europe, highlighting that age over 80 and large-cell transformation worsened survival rates.
  • *Results indicated that patients treated with mogamulizumab had significantly lower mortality rates, suggesting it is an effective treatment option for Sézary syndrome.

Fecal bacteria in surface water may indicate threats to human health. Our hypothesis is that village settlements in tropical rural areas are major hotspots of fecal contamination because of the number of domestic animals usually roaming in the alleys and the lack of fecal matter treatment before entering the river network. By jointly monitoring the dynamics of and of seven stanol compounds during four flood events (July-August 2016) at the outlet of a ditch draining sewage and surface runoff out of a village of Northern Lao PDR, our objectives were (1) to assess the range of concentration in the surface runoff washing off from a village settlement and (2) to identify the major contributory sources of fecal contamination using stanol compounds during flood events.

Background: New skin and soft tissue infections (SSTI) guidelines were published in 2019 in France, changing the recommended duration for antibiotic treatment. The objective of the present study was to assess the impact of the publication of the 2019 French guidelines on SSTIs on the duration of antibiotic prescription for erysipelas.

Methods: In a before-after study (a year before and a year after April 1st, 2019), we included all adult patients diagnosed with erysipelas in Reims University Hospital medical wards and the emergency department.

Background: GPP is a rare, chronic, neutrophilic skin disease, with limited real-world data characterizing patients with flares and the impact of flares on disease progression and morbidity.

Objective: Describe the clinical characteristics of patients with GPP, comorbidities, disease epidemiology and frequency and severity of flares, and compare patients with GPP with a matched severe psoriasis population.

Methods: In this population-based real-world cohort study an algorithm was developed to identify patients with GPP flares.

Article Synopsis
  • The study evaluated the effectiveness and safety of the drug omalizumab for treating bullous pemphigoid (BP) in patients who did not respond to standard treatments, analyzing data from 100 patients across 18 medical centers in France from 2014 to 2021.
  • 77% of patients achieved complete remission (CR), and 9% achieved partial remission, with a median time to CR of approximately 3 months, although 14% experienced relapses within a median follow-up of 12 months.
  • Higher baseline levels of anti-BP180-NC16A IgE were linked to better CR outcomes, while other factors like urticarial lesions or eosinophil

Routine clinical assays, such as conventional immunohistochemistry, often fail to resolve the regional heterogeneity of complex inflammatory skin conditions. We introduce MANTIS (Multiplex Annotated Tissue Imaging System), a flexible analytic pipeline compatible with routine practice, specifically designed for spatially resolved immune phenotyping of the skin in experimental or clinical samples. On the basis of phenotype attribution matrices coupled to α-shape algorithms, MANTIS projects a representative digital immune landscape while enabling automated detection of major inflammatory clusters and concomitant single-cell data quantification of biomarkers.

Background: Traditional systemic immunosuppressants and advanced therapies improve signs and symptoms of moderate-to-severe atopic dermatitis (AD). However, data are limited in severe and/or difficult-to-treat AD. In the phase 3 JADE COMPARE trial of patients with moderate-to-severe AD receiving background topical therapy, once-daily abrocitinib 200 mg and 100 mg showed significantly greater reductions in the symptoms of AD than placebo and significantly greater improvement in itch response (with abrocitinib 200 mg) than dupilumab at week 2.
