Rheumatology has an ______ component.

Rheumatology has an ______ component.

• A. Autoimmune
• B. Infectious
• C. Genetic
• D. Degenerative

Answer: (A)

Autoimmune processes are central to rheumatic diseases, where the immune system mistakenly targets the body's own tissues, producing chronic inflammation in joints and connective tissues. This autoimmune drive explains the classic inflammatory patterns seen in conditions like rheumatoid arthritis and systemic lupus erythematosus, often supported by autoantibodies such as rheumatoid factor, anti-CCP, or ANA. Infectious factors can trigger or mimic rheumatic symptoms, but they do not define the field’s typical mechanism. Degenerative changes, like those in osteoarthritis, arise from wear and tear rather than immune attack. Genetic predisposition exists and influences susceptibility, yet the defining feature of rheumatology remains immune-mediated inflammation.
