AI Article Synopsis

  • Cutaneous inflammation is a shared characteristic found in several systemic autoimmune rheumatic diseases (SARDs), particularly systemic lupus erythematosus, undifferentiated connective tissue disease, mixed connective tissue disease, and dermatomyositis, while it’s less common in primary Sjögren's syndrome.
  • Understanding whether the underlying processes of skin inflammation in these diseases are similar or distinct is crucial for the development of targeted treatments.
  • This review will explore the similarities and differences in inflammatory skin diseases across SARDs, emphasizing histopathology and highlighting recent advancements from single-cell technologies.

Article Abstract

Cutaneous inflammation is a common feature of several systemic autoimmune rheumatic diseases (SARDs) including systemic lupus erythematosus (SLE), undifferentiated connective tissue disease (UCTD), mixed connective tissue disease (MCTD) and dermatomyositis (DM) but is less common in other SARDs such as primary Sjögren's syndrome (pSS). It is important to understand whether the pathophysiological processes underlying skin inflammation are different or shared between SARDs to develop targeted therapies. This review will discuss commonalities and differences between inflammatory skin disease in SARDs focusing on histopathology and describe newer insights obtained from single-cell technologies.

Background: Tuberculosis (TB) remains a significant global health issue. Drug-resistant TB and comorbidities exacerbate its burden, influencing treatment outcomes and healthcare utilization. Despite the growing prevalence of TB comorbidities, research often focuses on single comorbidities rather than comorbidity patterns.

Detection of anti-MGL_1304 IgE using the ImmunoCAP system for diagnosis of type I allergy to sweat.

Background: Type I allergy to sweat is involved in the pathogenesis of atopic dermatitis (AD) and cholinergic urticaria (CholU), with MGL_1304 from Malassezia globosa being the major causative antigen. Currently, no standard diagnostic test exists for sweat allergy that uses serum.

Methods: The ImmunoCAP (iCAP) system to measure antigen-specific IgE was developed using recombinant MGL_1304 (rMGL_1304).

Background: Identification of predictive biomarkers is crucial for formulating preventive interventions and halting the progression of atopic march. Although controversial, the use of accessible markers to predict or detect early onset of atopic diseases is highly desirable. Therefore, this study aimed to investigate whether corneal squamous cell carcinoma antigen-1 (SCCA1) collected from infants can predict the development of atopic dermatitis and food allergy.

Canine atopic dermatitis (cAD) and feline atopic skin syndrome are inflammatory and pruritic skin diseases with both environmental and genetic factors. Genetic factors may include barrier defects and a predisposition to mount T helper 2 lymphocyte immune response when allergens are encountered. These diseases have repeatable patterns of skin and ear inflammation and commonly lead to Staphylococcal and Malassezia skin and ear infections.

Alterations in the lipid layer and intercellular corneocyte connections can lead to increased allergen penetration through the skin surface. A normal cutaneous microbiome keeps the opportunistic pathogen Staphylococcus pseudintermedius levels low, but allergic inflammation leads to decreased diversity and increase in S pseudintermedius. Keratinocytes sound the initial allergen alarm via cytokine signaling and promote T-helper 2 (Th-2) inflammation.
