Article Abstract

This report documents the first known cases of lepromatous leprosy in patients with chronic mucocutaneous candidiasis (CMC) linked to a gain-of-function mutation in the STAT1 gene. Two related patients, a mother and daughter, who both suffer from CMC and lepromatous leprosy, carry a heterozygous STAT1 mutation (c.821G>A; p.R274Q). Both individuals exhibited similarly high levels of total and phosphorylated STAT1 in CD4+ T cells and decreased interleukin 17A transcripts. This mutation underscores a complex relationship between genetic susceptibility to infections and the necessity to evaluate each case individually.

Purpose: Inborn errors of immunity (IEIs) caused by mutations in are associated with a broad range of clinical manifestations, ranging from relatively mild to life-threatening. Our aim was to give a clinical and molecular description of a Norwegian cohort with STAT1-related disease.

Methods: This is a descriptive epidemiological study.

Exocrine pancreatic insufficiency (EPI) arises from a deficiency in pancreatic enzymes, leading to malabsorption and varied symptoms such as gastrointestinal discomfort, weight loss and steatorrhea. Though EPI commonly follows chronic pancreatitis or pancreatic surgery, its delayed onset is rarely discussed. We report a unique case of EPI manifesting 29 years after pancreaticoduodenectomy.

Cardiovascular disease (CVD) remains one of the leading causes of death worldwide, with several well-established risk factors. Among dermatological conditions, psoriasis is a well-known contributor to cardiometabolic risk, while lichen planus (LP) remains an underexplored chronic inflammatory disorder in this context. This study aimed to comparatively assess the prevalence and clinical patterns of metabolic syndrome (MetS) components in patients with LP versus psoriasis and healthy controls, focusing on the intrinsic inflammatory burden in patients not receiving systemic therapy.

Behçet's syndrome (BS) is a chronic, relapsing inflammatory disease with multisystem involvement and prominent neutrophil activation. The neutrophil-to-lymphocyte ratio (NLR) has gained increasing attention as a potential surrogate marker for systemic inflammation. In this review we aimed to summarize and critically review the current evidence regarding the utility of NLR in BS, including its association with overall disease activity and specific organ involvement, as well as to explore its strengths and limitations as a clinical biomarker.

Acne vulgaris is a widespread, chronic inflammatory skin condition that significantly impacts patients' quality of life. Although oral isotretinoin remains the most effective treatment, recent evidence suggests that H-antihistamines such as desloratadine and levocetirizine may enhance acne therapy. This study assesses whether combining H-antihistamines to isotretinoin enhances treatment efficacy in acne vulgaris compared to isotretinoin alone.
