  • Work impact of immune‐mediated inflammatory skin diseases: A systematic review and meta‐analysis

    by Fanny C. Kpenou, Ju Hee Han, Marc Fadel, Tat‐Thang Vo, Hyun Jeong Ju, Tarik El Aarbaoui, Christopher E. M. Griffiths, Henry W. Lim, Lars E. French, Carsten Flohr, et al.

    Background: Patients with immune‐mediated inflammatory diseases (IMIDs) of the skin face challenges beyond visible signs. Despite their significant psychosocial burden, the global impact of skin IMIDs on work productivity has not been systematically reviewed. Objective: To evaluate the global burden of skin IMIDs on work productivity. Methods: We conducted a systematic review and meta‐analysis. Eight electronic databases (PubMed, Web of Science Core Collection, Embase, SciELO, KCI Korean Journal Database, Global Index Medicus, Informit and Google Scholar) were searched from inception to June 2024. We included quantitative studies reporting work‐related outcomes in adults (≥18 years) with alopecia areata, atopic dermatitis, hidradenitis suppurativa, psoriasis or vitiligo. For the meta‐analysis, studies had to report Work Productivity and Activity Impairment (WPAI), Work Limitations Questionnaire (WLQ) or sick leave duration. Two reviewers independently screened and extracted data. Risk of bias was assessed using validated tools. Data were pooled using frequentist and Bayesian approaches to ensure estimations robustness across heterogeneous designs and sample sizes. Results: Across 100 studies with a cumulative sample of 306,619 participants worldwide, skin IMIDs were consistently associated with impaired work functioning. Notably, the mean WPAI overall work impairment was 28.96 (95% CI 25.61; 32.31), and participants averaged 16.74 days of sick leave per year (95% CI 7.39; 26.1). Findings suggest that occupational impairment was influenced by psychosocial factors, thereby highlighting broader societal and economic consequences. Conclusion: Skin IMIDs substantially reduce work functioning and productivity worldwide, representing an underrecognized burden on individuals, employers and health systems. Better multidisciplinary strategies are needed to prevent occupational disadvantage and mitigate the economic and social impact of these chronic conditions.

    Statement from the frontal fibrosing alopecia international expert alliance: SOFFIA 2024

    by Nekma Meah, Jane Li, Dmitri Wall, Katherine York, Bevin Bhoyrul, Laita Bokhari, Lachlan Coulthard, Leila Asfour, Leonardo Spagnol Abraham, Daniel Asz‐Sigall, et al.

    Background: As the incidence of frontal fibrosing alopecia (FFA) continues to rise, there is a need for an optimal treatment algorithm for FFA. Objectives: To produce an international consensus statement on the treatment modalities and prognostic indicators of FFA. Methods: Sixty‐nine hair experts from six continents were invited to participate in a three‐round Delphi process. The final stage was held as a virtual meeting facilitated via Zoom. The consensus threshold was set at ≥66%. Results: Of 365 questions, expert consensus was achieved in 204 (56%) questions following completion of the three rounds. Three additional questions were included at the final meeting. The category with the strongest consensus agreement was disease monitoring (9; 100%). Questions pertaining to physical therapies achieved the least category consensus (15; 40%), followed by systemic therapy (45; 43%). Limitations: The study lacked sufficient representation from Africa and South America. Conclusions: SOFFIA highlights areas of agreement and disagreement among experts. Robust research is warranted to provide evidence‐based treatment recommendations.

    COLLAB: A Global Survey of Clinical and Laboratory Assessment in Alopecia Areata by Hair Specialists

    by Cathal O'COnnor, Aoife Boyle, Leila Asfour, Bevin Bhoyrul, Laita Bokhari, George Cotsarelis, Chantal Cotter, Brittany Craiglow, Lara Cutlar, Rachita Dhurat, et al.

    Background: Alopecia areata (AA) is a common non‐scarring alopecia. Data continue to emerge on associations with autoimmune and other conditions. Janus kinase inhibitors (JAKi) are increasingly used to treat AA.Objectives: The aim was to assess variation in laboratory testing in patients with AA among hair experts internationally and to compare subspecialized clinical practice to current guidelines.Methods: Thirty hair experts from 14 countries and six continents contributed to develop a 24‐item survey collecting demographic information on respondents; methods of severity assessment; and laboratory testing practices in AA for mimics, contributory factors, associations, and workup for systemic therapy. The survey was distributed to a global network of expert hair specialists.Results: Of 214 respondents, 79.9% (171/214) had special interest/expertise in hair loss disorders, and 35.5% (n = 76) were based in Europe. Most cared for both adults and children (87.9%, n = 188). For clinical assessment, almost two‐thirds (63.6%, n = 136) used the Severity of Alopecia Tool and 38% (n = 84) used the Dermatology Life Quality Index. Only 24.3% (n = 52) typically tested for alternative infectious or inflammatory diagnoses, 39.7% (n = 85) typically tested for contributory conditions such as nutritional deficiencies, and 50.9% (n = 109) typically tested for co‐existent autoimmune illnesses. Thyroid function testing was routinely performed in 73.4% (n = 157) and complete blood count (CBC) was checked in 65.9% (n = 141). Compared to conventional systemic therapy, experts were more likely to check lipid levels, creatine kinase, coagulation profiles, thrombophilia screens, tuberculosis blood testing, hepatitis B and C serology before prescribing JAKi.Conclusions: Real world practice of laboratory testing for AA by hair experts, who may see more severe or complex alopecia, is variable. Most experts routinely perform thyroid function and CBC testing. We discuss evidence for indications for testing for AA mimics, contributory factors, associated autoimmune conditions, and before systemic therapy. Further research is required to characterise the role of laboratory testing in AA.

    Testing for methicillin-resistant Staphylococcus aureus in the anterior nares for antibiotic de-escalation in patients presenting with acute skin and soft tissue infections: systematic review and meta-analysis

    by Sara Bohjanen, Connor Goldstick, Maria Hordinsky

    Objective: To improve the understanding of appropriate antibiotic de-escalation and stewardship by consolidating the evidence on screening for methicillin-resistant Staphylococcus aureus (MRSA) colonization of the nares to predict MRSA in acute skin and soft tissue infections (SSTIs).Methods: This meta-analysis was performed according to PRISMA guidelines. Six databases were searched by two reviewers for articles on MRSA detection in the nares and acute SSTIs. The quality and risk of bias of the articles were then assessed. The primary outcomes of interest were pooled sensitivity and specificity. Sub-analyses were also performed to test for heterogeneity.Results: After screening 1040 records, 15 articles (n = 1,970) were included in the meta-analysis. Using MRSA nares screening to predict MRSA in acute SSTIs had an overall specificity of 0.949 and sensitivity of 0.474. With a prevalence of 29.1%, the calculated NPV was 0.815. There were sub-analyses on various study variables, such as study location, participant age, and detection by polymerase chain reaction versus culture. The only significant finding was an increased sensitivity for adults (0.543) compared to pediatric participants (0.285).Discussion: To our knowledge, this is the first meta-analysis that focuses on the performance of MRSA nares screening for predicting MRSA infection in patients presenting with acute SSTIs. The baseline prevalence of MRSA SSTIs is important for interpreting the screening results, and the prevalence is influenced by geography and patient factors. This clinical context must be considered before utilizing MRSA nares screening for acute SSTIs.


  • Hydroxychloroquine may be beneficial as an adjuvant therapy for folliculitis decalvans: a 5-year retrospective study with 49 patients

    by Isabella Doche, Mirian N Sotto, Maria K Hordinsky, Isabela P Melhado, Paula Gerlero, Maria Cecília Rivitti-Machado

    Folliculitis decalvans (FD) is a chronic and recurrent neutrophilic scarring alopecia that mostly affects the vertex scalp of young male patients. It manifests as painful alopecic lesions surrounded by pustules, tuftings and intense scalp fibrosis. However, the occurrence of less active or ‘lichen planopilaris-like’ forms of FD questions the exact role of Staphylococcus aureus in the pathogenic mechanism of this disease. The management of FD is very challenging, as relapses are frequent and prolonged use of combined antibiotics is often required. Recent evidence showed the presence of S. aureus and lymphocytic inflammation also in nonlesional FD scalp. This suggested the potential use of immunomodulating drugs such as hydroxychloroquine to better control the chronic inflammatory status of this ­disease.
