AI Article Synopsis

  • The study investigates the role of anti-PSMA1 antibodies in idiopathic nephrotic syndrome (INS) among children, aiming to understand its effects on podocyte function.
  • Researchers found that levels of these antibodies were higher in INS patients and correlated with urinary protein levels, indicating an association with disease severity.
  • Experiments in mice and zebrafish demonstrated that PSMA1 is crucial for maintaining podocyte structure and function, with deficiencies leading to significant kidney damage and morphological changes.

Introduction: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with limited reliable diagnostic biomarkers. This study evaluates the utility of DEAD-box helicase 5 (DDX5) as a diagnostic and differential marker for SLE and assesses the performance of a capture bead-based flow cytometry (CBFCM) method for detecting serum proteins.

Method: Serum samples were collected from 52 patients with SLE, 38 patients with rheumatoid arthritis (RA), 49 patients with lung cancer (LC), and 50 healthy controls (HCs).

Objectives: The feasibility of corticosteroid withdrawal (CW) for Takayasu arteritis (TAK) remains uncertain. Two autoantibodies (Abs) are identified against endothelial protein C receptor (EPCR) and scavenger receptor class B type 1 (SR-BI) in TAK, determining its three subgroups. This study aimed to evaluate CW using tocilizumab (TCZ) and its association with the Ab profile.

We report a patient with autonomic dysfunction following acute SARS-CoV-2 infection, presenting progressively worsening severe orthostatic hypotension to the point where she could no longer sit or stand. The patient experienced a delay in diagnosis after an initial misdiagnosis of a functional neurological disorder. Persistent orthostatic symptoms prompted us to re-examine the diagnosis and explore other diagnostic tools, which ultimately allowed us to identify and treat severe immune-mediated orthostatic hypotension (OH).

Objectives: Autoantibodies mimicking alloantibodies (referred to as mimicking antibodies) are a type of specific antibody that reacts with all red blood cells, but exhibits a stronger reaction with red blood cells expressing the target antigens. This study aimed to explore immunohematologic methods for identifying mimicking antibodies, autoantibodies and alloantibodies, and to formulate safe transfusion strategies based on the results.

Methods: ABO, Rh blood types and direct antiglobulin test were determined using the tube saline method.

Desmosomes are adhesive cell contacts abundant in tissues exposed to mechanical strain, such as the stratified and simple epithelia of the epidermis and mucous membranes, as well as the myocardium. Besides their role in mechanical cell cohesion, desmosomes also modulate pathways important for tissue differentiation, wound healing and immune responses. Dysfunctional desmosomes, resulting from pathogenic variants in genes encoding desmosomal components, autoantibodies targeting desmosomal adhesion molecules or inflammation, cause the life-threatening diseases arrhythmogenic cardiomyopathy and pemphigus and contribute to the pathogenesis of inflammatory bowel diseases.
