The Influence of Genital Lichen Sclerosus on Sexual Health and Well-being: A Tripartite Comparative Analysis.

Objectives: Genital lichen sclerosus (LS) is a chronic mucocutaneous disorder causing considerable discomfort. Despite this, comprehensive comparison of LS impacts on quality of life (QoL), particularly on men's health or relative to other dermatological conditions like pemphigus, are sparse. This research aims to discern the effects of LS on sexual functionality and overall QoL, benchmarking against pemphigus patients and healthy controls.

Cytokine profiling reveals HLA-linked Th2 and Th17 driven immune activation in pemphigus vulgaris patients and genetically susceptible healthy controls.

Introduction: Cytokines and chemokines direct the inflammatory response and may serve as markers of immune dysregulation in Pemphigus vulgaris (PV), an autoimmune blistering skin disorder. Previous studies on limited numbers of patients and cytokine profiles in PV have produced equivocal results regarding the role these mediators play in disease.

Methods: In this study, we interrogated serum samples from 116 PV patients and 29 healthy controls by multiplexed bead array assays across a comprehensive set of cytokines and chemokines covering several functional categories, including IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, IL-17, IL-21, IL-22, IL-23, TNFα, IFNγ, MCP-1, and Eotaxin.

The lost generation of Pemphigus populiglobuli (Hemiptera, Aphididae): exploring the taxonomy of the Svalbard aphids of genus Pemphigus.

Species identification within the aphid genus Pemphigus Hartig, 1839 poses challenges due to morphological similarities and host-plant associations. Aphids of this genus generally exhibit complex life cycles involving primary hosts (poplars) and secondary (mostly unrelated herbaceous) host-plants, with some species relying solely on root-feeding generation. An example is a representative of the genus Pemphigus, trophically associated with grass roots, found in the High Arctic Svalbard archipelago.

Life-threatening dermatoses.

While rare, life-threatening dermatoses encompass various inflammatory, infectious, vasculitic/vasculopathy, paraneoplastic, and neoplastic skin diseases. Complications include skin barrier dysfunction, secondary infection, and internal organ involvement. Skin signs may serve as a critical window into systemic disease.

Oral pemphigus vulgaris diagnostic characteristics and treatment: a systematic review.

Pemphigus vulgaris (PV) is a rare, potentially fatal, immune-mediated chronic disease characterized by the presence of bullous intraepithelial lesions on mucous membranes and skin. This study aimed to perform a systematic literature review covering PV clinical and histopathological aspects and treatment. The literature searches were carried out in the Pubmed, Periódicos Capes, Scopus, Science Direct, Web of Science and Scielo databases.

Pathophysiology of oral lesions subsequent to SARS-CoV-2 vaccination: A systematic review.

Amidst worldwide reports of adverse oral lesions subsequent to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, the current systematic review planned to determine the prevalence of adverse oral events in adult individuals (≥18 years) after SARS-CoV-2 vaccination, emphasizing upon the type and dose of vaccine, time of onset, and underlying pathophysiology. The registered protocol (PROSPERO CRD42023421307), conforming with PRISMA guidelines, included an all-inclusive literature search through online databases, consisting of Scopus, PubMed/MEDLINE, Web of Science, Lilacs, Livivo, and PROSPERO, completed on 2 May 2023, followed by assessment of risk of bias by Joana Briggs Institute Evaluation Checklist. Due to the paucity of literature, case reports and case series were included.

Pemphigus Vulgaris With Esophageal Involvement in an Atopic Child Successfully Treated With Dupilumab.

We report the case of a 3-year-old boy who was diagnosed with childhood pemphigus vulgaris having developed oral lesions, gastrointestinal symptoms with esophageal involvement, and failure to thrive. He had a markedly increased total serum IgE level and peripheral blood eosinophilia. The pemphigus was recalcitrant to conventional therapies and, based on the coexisting characteristics of Th2 immune deviation, he was treated with dupilumab and has had sustained clinical improvement since starting treatment.

Refractory benign familial pemphigus successfully treated with dupilumab: a case series.

Benign familial pemphigus (BFP) is a chronic autosomal dominant dermatosis characterized by the appearance of flaccid blisters which evolve to painful erythematous macerated plaques and erosions in intertriginous areas. While different medical therapies for BFP exist, current treatments are not consistently effective, and symptoms often cause decreased quality of life. We report a case series of three patients with refractory moderate-to severe BFP which have been successfully treated with dupilumab, describing clinical evolution within a follow-up period of 18 months.

The monitoring of B lymphocytes in non-lymphoma patients following rituximab treatment.

RTX was initially used for non-Hodgkin's lymphoma treatment and has been used in the clinical treatment of various autoimmune diseases as well as in antirejection and immune induction therapy for kidney transplant recipients. Following RTX treatment, the time for B cell regeneration varies among patients, but there is no unified recommendation for the frequency of B cell monitoring. This study aimed to investigate the clinical significance of periodic monitoring of peripheral blood B lymphocytes in individualized immunotherapy following rituximab (RTX) treatment in patients with different diseases.

Anti-vitamin D antibodies.

Background: Low vitamin D levels are commonly observed in autoimmune diseases, suggesting a potential role in disease pathogenesis. The presence of anti-vitamin D antibodies may contribute to these deficiencies and influence autoimmune processes.

Objective: To review and analyze studies investigating the occurrence of anti-vitamin D antibodies in autoimmune diseases.

Immunosuppressants in dermatology on vaccine immunogenicity: a prospective cohort study of pemphigus patients in the pandemic.

Introduction: Both cellular and humoral responses are important for vaccine protection, but recommendations on immunosuppressants in dermatology are largely based on pre-pandemic experiences. This study aimed to investigate the impacts of immunosuppressants on humoral and cellular immunogenicity to COVID-19 vaccinations in pemphigus patients.

Methods: SARS-CoV-2-naïve pemphigus patients and age-, and sex-matched healthy controls were recruited from multiple tertiary medical centers during 2021-2023.

Case Report: A rare pediatric case of paraneoplastic pemphigus associated with Castleman disease misdiagnosed as Behçets disease.

Castleman disease (CD) is a rare lymphoproliferative disease known as angiofollicular lymph node hyperplasia, firstly reported in 1954. It mainly occurs in adults, presenting with a wide range of clinical manifestations, including paraneoplastic pemphigus (PNP). PNP is a rare and often life-threatening autoimmune disorder characterized by painful blisters and erosions on the skin and mucous membranes.

Prevalence of Fungal Infections in Pemphigus Patients: A Systematic Review and Meta-Analysis.

Background: Pemphigus is a life-threatening autoimmune disease characterised by blistering skin and/or mucous membranes. The present study aimed to determine the prevalence of fungal infections in the pemphigus population.

Methods: Different databases were searched to gain access to all studies on the prevalence of fungal infections published up to the 31st of May 2024.

Retroperitoneal unicentric Castleman disease presenting with paraneoplastic pemphigus.

Castleman disease is a benign lymph node hyperplasia with two histological subtypes. In the case reported here, a young adult male presented with mucocutaneous lesions mimicking common dermatological conditions. Suspicion of an underlying systemic disease arose when the routine clinical care of the skin lesions failed to cure them.
