Mixed cryoglobulinemic vasculitis (CV) is occasionally caused by autoimmune diseases including systemic sclerosis. Multiorgan involvement such as skin, kidney, and peripheral nerve involvement is common in mixed CV. However, central nervous system (CNS) involvement is extremely rare. Here, we report a case of overlap syndrome of limited cutaneous systemic sclerosis and mixed cryoglobulinemic vasculitis with CNS involvement. The neurologic deficits and systemic symptoms improved promptly after steroid and cyclophosphamide therapy.

Anti-CD20 monoclonal antibodies are gaining clinical relevance in the nephrology community due to their demonstrated efficacy and favorable safety profiles across short-, medium-, and long-term use. Initially developed for hematologic malignancies and multiple sclerosis, B-cell depletion therapies are now being investigated across a broader spectrum of autoimmune diseases, including glomerulopathies, both with and without associated podocytopathy. Recent advances have led to the development of novel anti-CD20 agents that are being used not only as potential alternatives to corticosteroids but also as adjunctive therapies in complex clinical settings.

Objective: To evaluate the efficacy of baricitinib in combination therapy for managing refractory, rapidly progressive systemic sclerosis (SSc) with severe cardiac conduction defects and interstitial lung disease (ILD).
Methods: A 48-year-old male patient with SSc complicated by significant cardiac enlargement, third-degree atrioventricular block, heart failure, progressive ILD, and partial intestinal obstruction was included in the study. Prior treatments with mycophenolate mofetil (MMF), tacrolimus, and cyclophosphamide (CTX) had shown limited efficacy.

Systemic sclerosis (SSc) is an autoimmune rheumatic disease marked by excessive extracellular matrix deposition, causing fibrosis, endothelial dysfunction, and microvascular injury. There are two major types of SSc, limited and diffuse. SSc can affect any organ, leading to dysfunction and failure.

Polymyositis with concomitant scleroderma is a rare, progressive condition with profound consequences if not addressed promptly. Severity and symptom presentation varies between patients, and much is unknown about how best to treat overlapping connective tissue diseases. This case discusses the rare presentation, medical evaluation, and successful treatment of a 46-year-old woman with excessive muscle atrophy, weakness, and tissue fibrosis, who was diagnosed with overlapping connective tissue disorder after extensive work up that included a muscle biopsy, skin punch biopsy, and autoantibody lab work.

Mitochondria play a crucial role in reactive oxygen species (ROS)-dependent rheumatic diseases, including ankylosing spondylitis, osteoarthritis (OA), systemic lupus erythematosus (SLE) and scleroderma. Mitochondrial DNA (mtDNA), which encodes mitochondrial proteins, is more vulnerable to oxidants compared to nuclear DNA. When mtDNA gets damaged, it leads to mitochondrial dysfunction, such as electron transport chain impairment and loss of mitochondrial membrane potential.
