Immune-mediated comorbidities in patients with psoriasiform eczema are common. It can be challenging to manage multiple immune-mediated diseases, especially considering that biologic treatments are prone to causing paradoxical effects. The aim of this retrospective observational case series was to describe the course of both psoriasiform eczema and immune-mediated comorbidities in five patients treated with upadacitinib for psoriasiform dermatitis. Five patients, all male, were included. All the patients suffered from psoriasiform eczema. Moreover, two of the patients suffered from alopecia areata, two from vitiligo, one from ulcerative colitis and one from hidradenitis suppurativa. In all cases, the treatment with upadacitinib was rapidly effective on the eczema. The effectiveness on alopecia areata was good in both cases, while the results on vitiligo were only partial. The only case of ulcerative colitis achieved complete remission, while the case of hidradenitis suppurativa experience partial improvement. In conclusion, upadacitinib was effective in treating not only psoriasiform eczema, but also several immune mediated comorbidities. Additional studies are necessary to determine the efficacy of upadacitinib in alopecia areata, vitiligo and hidradenitis suppurativa. [ABSTRACT FROM AUTHOR]

Background Artificial intelligence (AI) is reshaping healthcare, using machine and deep learning (DL) to enhance disease management. Dermatology has seen improved diagnostics, particularly in skin cancer detection, through the integration of AI. However, the potential of AI in automating immunofluorescence imaging for autoimmune bullous skin diseases (AIBDs) remains untapped. While direct immunofluorescence (DIF) supports diagnosis, its manual interpretation can hinder efficiency. The use of DL to classify DIF patterns automatically, including the intercellular (ICP) and linear pattern (LP), holds promise for improving the diagnosis of AIBDs. Objectives To develop AI algorithms for automated classification of AIBD DIF patterns, such as ICP and LP, in order to enhance diagnostic accuracy, streamline disease management and improve patient outcomes through DL-driven immunofluorescence interpretation. Methods We collected immunofluorescence images from skin biopsies of patients suspected of having an AIBD between January 2022 and January 2024. Skin tissue was obtained via a 5-mm punch biopsy, prepared for DIF. Experienced dermatologists classified the images as ICP, LP or negative. To evaluate our DL approach, we divided the images into training (n = 436) and test sets (n = 93). We employed transfer learning with pretrained deep neural networks and conducted fivefold cross-validation to assess model performance. Our dataset's class imbalance was addressed using weighted loss and data augmentation strategies. The models were trained for 50 epochs using Pytorch, achieving an image size of 224 × 224 pixels for both convolutional neural networks (CNNs) and the Swin Transformer. Results Our study compared six CNNs and the Swin Transformer for AIBD image classification, with the Swin Transformer achieving the highest average validation accuracy (98.5%). On a separate test set, the best model attained an accuracy of 94.6%, demonstrating 95.3% sensitivity and 97.5% specificity across AIBD classes. Visualization with Grad-CAM (class activation mapping) highlighted the model's reliance on characteristic patterns for accurate classification. Conclusions The study highlighted the accuracy of CNNs in identifying DIF features. This approach aids automated analysis and reporting, offering reproducibility, speed, data handling and cost-efficiency. Integrating DL into skin immunofluorescence promises precise diagnostics and streamlined reporting in this branch of dermatology. [ABSTRACT FROM AUTHOR]

Background: Psoriasis is a chronic inflammatory skin condition that affects millions of individuals worldwide, impacting their physical and emotional well-being. The management of psoriasis requires effective communication and a strong physician–patient relationship. Objective: We aim to develop a novel algorithm to enhance patient well-being and care in moderate-to-severe psoriasis, considering the time constraints that dermatologists have in public hospitals. Methods: This project employed a multidisciplinary approach, involving collaboration between 14 experienced dermatologists (referred to as Key Opinion Leaders: KOLs) and a psychologist. During three separate meetings (an initial virtual session, a face-to-face meeting, and a final virtual meeting), an algorithm (Embracing Patients' Well-being in their Journey of Moderate-to-Severe psoriasis: EMPATHY), describing the patient's reception through the entire first visit and follow-up visits, was developed and refined. Results: The EMPATHY algorithm provides a step-by-step approach from the moment the patient arrives at reception, through the first visit and on to subsequent visits. This algorithm fills a critical gap in the existing guidelines by specifically addressing how to foster empathy during psoriasis patient visits within time-limited consultations. The algorithm outlines patient-centered strategies at each visit. Key aspects include creating a welcoming environment, active listening, respecting privacy, tailoring communication styles, and managing patient expectations. Conclusions: The EMPATHY algorithm represents a novel and promising approach to improving patient care and well-being in moderate-to-severe psoriasis. Developed together by dermatologists and a psychologist, this algorithm offers healthcare providers practical guidance for managing both initial and follow-up patient visits. While further validation is necessary, the potential for adapting the EMPATHY algorithm to diverse healthcare settings and patient populations holds promise for improving patient outcomes across various chronic conditions.

Background: Trypanophobia or "needle phobia" represents a potential hindrance to the effective management of chronic diseases whenever an injectable therapy might be required, especially in case of frequent administrations. Psoriasis, a chronic dermatologic disease, can be effectively treated with biologic drugs administered subcutaneously. Thankfully, anti‐IL‐23 drugs require few administrations per year and are available in prefilled pens that hide the needle, thus representing a convenient option in patients with trypanophobia. Methods: An observational multicentric study was conducted on patients with moderate‐to‐severe psoriasis who were treated with 75 mg × 2 risankizumab prefilled syringe therapy for more than 6 months and reported a loss of efficacy measured by the Psoriasis Area and Severity Index (PASI) from PASI 90 to PASI 75 attributed to a reduction of adherence due to trypanophobia. The patients were switched to 1 prefilled pen of risankizumab 150 mg and asked to fill out the Self‐Injection Assessment Questionnaire (SIAQ) before and after the injection at week 0 and at the following administration after 12 weeks. Subjects scored each item of the SIAQ on a 5‐point scale, scores were later transformed from 0 (worst experience) to 10 (best experience). Results: Twenty‐two patients were enrolled. The mean SIAQ predose domain scores were 5.5 for feelings about injection, 6.2 for self‐confidence, and 6.4 for satisfaction with self‐injection. After dose scores were higher (> 8.5) for each of the six domains at Week 0 and even higher after 12 weeks (> 9.0). Conclusions: User‐friendly devices, such as prefilled pens, and a lower number of injections improved patient satisfaction in a group of patients with psoriasis on treatment with biologic drugs. We believe that treatment adherence could be positively influenced by such changes in the way of administration of a biologic treatment. [ABSTRACT FROM AUTHOR]

This article discusses a series of 10 cases where patients with psoriasis developed paradoxical eczema (PE) exclusively on their ears after being treated with biologic drugs. The patients experienced the onset of PE at different times after starting biologic therapy, with a median time of 12 months. The implicated biologics included tumor necrosis factor (TNF) inhibitors, anti-interleukin (IL)-17 drugs, and anti-IL-23p19 drugs. Treatment with topical steroids and systemic therapy was successful for some patients, while others had to discontinue their current biologic treatment or switch to a different class of biologic. The duration of eczema before resolution varied depending on the treatment approach. The article suggests that the pathogenesis of PE may be related to the mechanism of action of the involved drugs and alterations in the skin microbiome. Further research is needed to better understand this phenomenon. [Extracted from the article]

Background: The incidence of syphilis has increased in high-income countries in the past few decades, especially among men who have sex with men. In the present study, we aimed to analyze the correlations between atypical syphilis manifestations and the demographic, clinical, and laboratory features of patients and to review unusual presentations of syphilis reported in the literature. Methods: We conducted a retrospective analysis of 307 patients with syphilis diagnosed between 1 January 2013 and 31 October 2023 at the sexually transmitted infection (STI) centers of the University of Genoa and University of Foggia with both typical and atypical manifestations of disease. Results: In our series, atypical manifestations were detected in 25.8% of the patients, especially in the secondary stage of the disease. Lesions with annular morphology and lesions presenting as itchy erythematous scaly plaques with a psoriasiform appearance were the most common atypical presentations of secondary syphilis. A statistical analysis revealed that homosexual orientation, syphilis reinfection, and venereal disease research laboratory (VDRL) titers > 1:32 were correlated with atypical manifestations. Conclusions: Our study demonstrates that the spectrum of syphilis manifestations, in all the stages of the disease, is wide; atypical manifestations often pose diagnostic challenges, may delay the provision of appropriate treatment, and facilitate the spread of the infection.
