Vasculitis Overview – types and classification

Vasculitis explained: learn types, causes, symptoms, and complications of blood vessel inflammation — including giant cell arteritis, Takayasu, Kawasaki, ANCA-associated vasculitis, IgA vasculitis, and anti-GBM disease. This concise video breaks down primary vs. secondary vasculitis and categorizes disorders by vessel size (large, medium, small), plus variable and single-organ vasculitides. Viewers will understand mechanisms (immune attack, immune complexes, ANCA antibodies, anti-GBM), hallmark features like temporal artery pain, absent pulses, fever and mucocutaneous signs in Kawasaki, and life‑threatening risks such as blindness, aneurysm, thrombosis, lung hemorrhage, and renal failure. Practical insights include common triggers for secondary vasculitis—autoimmune diseases, infections (hepatitis B/C, syphilis), drugs, and malignancy—and how presentations guide diagnosis and urgency of treatment. Packed with clear clinical examples (GCA, Takayasu, PAN, MPA, GPA, EGPA, IgA vasculitis, cryoglobulinemia, Behçet’s, Cogan syndrome), the video emphasizes early recognition, the role of antibodies (MPO/PR3 ANCA, anti‑GBM), and key complications to watch for. Whether you’re a medical student, clinician, or patient seeking a solid overview, this engaging, evidence-focused guide makes complex vasculitis syndromes accessible and actionable. Watch to sharpen diagnostic thinking and learn which red flags require prompt intervention.
