METHODS: This study was a nationwide population-based case-control study about the association between the psoriatic disease risk among patients with a history of appendicitis in Taiwan. The study population consisted of newly diagnosed psoriatic disease with at least two outpatient visits, and the control group included those patients without psoriatic disease at the same index date...

INTRODUCTION: Physician assistants (PAs) are often members of dermatologic care teams. Adequate knowledge of dermatologic conditions in skin of color (SOC) is crucial to proper diagnosis, treatment, and patient satisfaction. The objective of this study was to increase PA students' objective knowledge of and comfort level with evaluating dermatologic conditions in SOC. METHODS: Eligible participants included 36 PA students at a major metropolitan medical center during the 2022 to 2023 academic year...

IMPORTANCE: The epidemiological link between immune-mediated diseases (IMIDs) and cardiovascular disease has often been attributed to systemic inflammation. However, the direction of causality and the biological mechanisms linking cardiovascular disease with IMIDs are incompletely understood. Given the robust epidemiological association and the growing body of supportive mechanistic evidence, psoriasis is an exemplary IMID model for exploring this relationship. OBJECTIVE: To assess the bidirectional relationships between genetic predictors of psoriasis and the 2 major forms of cardiovascular disease, coronary artery disease (CAD) and stroke, and to evaluate the association between genetic predictors of cardiovascular disease with 9 other IMIDs...

The use of medications which target the JAK-STAT signaling pathway, also known as janus kinase (JAK) inhibitors, has rapidly increased in recent years. Patient perceptions, opinions, and concerns regarding the use of JAK inhibitors are largely uninvestigated. Our objective is to better understand patient concerns, reported side effects, and sentiments regarding the use of JAK inhibitors for dermatologic disease. The authors performed a cross-sectional analysis of the most frequented subreddits for dermatologic disease in which JAK inhibitors have obtained FDA approval (r/atopic dermatitis, r/psoriasis, r/alopecia areata, r/vitiligo, and r/eczeJAKS)...

Introduction Nail disorders account for an important component of all dermatological conditions. Nail abnormalities can result from local pathology or systemic diseases. Pathologies can lead to pain and impaired fine touch and are aesthetically distressing. Clinical assessment of nail pathologies is seldom accurate; moreover, the limited available investigative modalities make it difficult to correctly diagnose the disorders. Nail biopsies provide crucial histological information, especially for nail-limited dermatoses, though they are infrequently used and technically challenging...

INTRODUCTION: Many studies have shown significant alterations in the gut microbiome of patients with psoriasis compared to healthy controls. AIM: The primary objective of the current research was to explore the impact of gut microbiome composition on the progression and severity of plaque psoriasis. MATERIAL AND METHODS: A total of 20 patients with moderate-to-severe psoriasis and 20 healthy individuals were recruited and provided a stool sample to assess the gut microbiome...

Onychomycosis, a nail infection caused by dermatophytes, yeast, and molds makes up roughly half of all onychopathies and is the most prevalent nail condition in the world. Clinically, nail psoriasis and onychomycosis can frequently be difficult to distinguish from one another. To assess the prevalence of onychomycosis in patients with psoriasis. Fifty patients with psoriasis associated with nail disease were included in this study. After taking clinical history, nail samples were gathered for dermoscopic inspection, culture, direct microscopy with 20% KOH solution, and nail clipping with PAS stain...

Psoriatic arthritis (PsA) is an immune-mediated, chronic inflammatory joint disease that commonly occurs as a complication of psoriasis. EGF-like repeats and discoidal I-like domain 3 (EDIL3) is a secreted protein with multiple structural domains and associated with various physiological functions. In this study, we employed a mannan-induced psoriatic arthritis model to investigate the impact of EDIL3 on PsA pathogenesis. Notably, a downregulation of EDIL3 expression was observed in the PsA model, which correlated with increased disease severity...

A man in his 50s with a history of psoriasis was evaluated for acute on chronic left ankle pain. His symptoms were attributed to psoriatic arthritis, and he tried several immunosuppressive regimens without improvement. Further diagnostic workup confirmed Coccidioides immitis/posadasii septic monarthritis thought secondary to a known remote history of Valley fever while residing in Arizona and subsequent reactivation in the setting of immunosuppression. The patient ultimately required prolonged anti-fungal therapy and multiple surgical debridements...

BACKGROUND: Due to the diversity of the immune repertoire (IR), reconstructing full-length IR using traditional short-read sequencing has proven challenging. METHODS: A full-length IR sequencing (FLIRseq) work flow was developed with linear rolling circle amplification and nanopore sequencing. Its accuracy and quantification ability were verified by plasmid mixtures and commercial B-cell receptor/T-cell receptor sequencing (BCR/TCR-seq) based on short reads. IRs in tissues and the peripheral blood from 8 patients with acute lymphoblastic leukemia, 3 patients with allergic diseases, 4 patients with psoriasis, and 5 patients with prostate cancer were analyzed using FLIRseq...

BACKGROUND: Psoriasis is a chronic inflammatory skin disease. To date, there are no serum biomarkers for psoriasis that have been validated to diagnose or treat psoriasis. METHODS: Peptidase inhibitor 3 (PI3) levels in serum were measured using chemiluminescence immunoassay (CLIA) in two independent cohorts including healthy controls (HC) and patients diagnosed with chronic urticaria (CU), chronic eczema (CE), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriatic arthritis (PsA), or psoriasis vulgaris (PV)...

Pityriasis rubra pilaris (PRP) is a rare, chronic, inflammatory papulosquamous skin disease. Here, we report a case of a 43-year-old female with a known history of atopic dermatitis, bronchiectasis, and goiter who presented with a six-month history of persistent itchy skin lesions on her extremities. A skin examination revealed multiple diffuse, well-defined, fine, scaly erythematous patches with areas of spared skin over all four extremities, along with palmoplantar keratoderma. The trunk was spared. The differential diagnosis included atopic eczema, pityriasis rubra pilaris, dermatomyositis, mycosis fungoides, parapsoriasis, psoriasis, and drug-induced eczematous dermatitis...

MATERIALS AND METHODS: A cross-sectional, self-administered question-based study was conducted at Siriraj Hospital. Participants were psoriasis patients older than 18 years of age with past or current genital involvement...

BACKGROUND: To clarify the controversy between inflammatory or autoimmune skin diseases and thyroid diseases, we performed two-sample Mendelian randomization (MR) analyses. PARTICIPANTS: Genetic data on factors associated with atopic dermatitis (AD, n=40,835), seborrheic dermatitis (SD, n=339,277), acne (n=363,927), rosacea (n=299,421), urticaria (n=374,758), psoriasis (n=373,338), psoriasis vulgaris (n=369,830), systemic lupus erythematosus (SLE, n=14,267), vitiligo (n=353,348), alopecia areata (AA, n=361,822), pemphigus (n=375,929), bullous pemphigoid (BP, n=376,274), systemic sclerosis (SSc, n=376,864), localized scleroderma (LS, n=353,449), hypothyroidism (n=314,995 or n=337,159), and hyperthyroidism (n=281,683 or n=337,159) were derived from genome-wide association summary statistics of European ancestry...

Maintaining peripheral immune tolerance and preventing harmful autoimmune reactions is a fundamental task of the immune system. However, these essential functions are significantly compromised during autoimmune disorders, creating a major challenge in treating these conditions. In this context, we provide an overview of research on small spleen polypeptides (SSPs) that naturally regulate peripheral immune tolerance. Alongside outlining the observed effects of SSPs, we summarize here the findings on the cellular and molecular mechanisms that underlie their regulatory impact...

In the setting of increasing patient-reported cannabidiol (CBD) usage in the dermatologic setting, it is of great importance that clinicians become aware of potential medication interactions that may arise from cannabidiol usage in order to ensure safe and efficacious medication therapy. This brief review aimed to bring awareness to the mechanism of CBD while highlighting potential interactions between CBD and medication therapy for commonly encountered dermatologic conditions, including acne, allergic contact dermatitis, atopic dermatitis, pruritus, skin aging, skin cancer, and psoriasis...

INTRODUCTION: With newer biologics, the achievement of complete skin clearance has become an attainable treatment goal for patients with plaque psoriasis. We evaluate how improvements in Psoriasis Area and Severity Index (PASI) responses, particularly at incremental improvements approaching complete skin clearance (PASI 100), translate into improvements in health-related quality of life (HRQoL) and patient-perceived symptoms. METHODS: Data from the BE RADIANT phase 3b trial (NCT03536884) and its open-label extension (OLE), pooled across all study visits and treatments over 16 weeks (randomised patients) and 2 years (patients entering the OLE), were analysed using mixed-effects logistic regression models...

BACKGROUND: For patients with psoriasis, discontinuation of biologics following remission has become more common in daily practice. OBJECTIVE: We aimed to identify predictors and construct a predictive model for time to relapse following withdrawal from biologics. METHODS: This 12-year, multicenter, observational cohort study was performed in six dermatology centers between February 2011 and February 2024. We identified biological treatment episodes in patients with moderate-to-severe psoriasis and included only treatment episodes in which a clinical response (≥ 50% reduction in Psoriasis Area and Severity Index score [PASI 50] from baseline) was achieved and the patient withdrew from biological therapy with a well-controlled status (PASI < 10 and ≥ 50% improvement in PASI from baseline)...
