Question

Quizplus · Accepted Answer

Rheumatoid arthritis is indeed an autoimmune disease, where the body's immune system mistakenly attacks its own tissues, affecting primarily the joints but can also involve other organ systems. Osteoarthritis, on the other hand, is a degenerative joint disease caused by wear and tear on the joints over time, not an autoimmune process. Methotrexate is commonly used in the treatment of rheumatoid arthritis, not primarily for osteoarthritis. Osteoarthritis is more common than rheumatoid arthritis. Rheumatoid arthritis typically affects the small joints in the hands and feet, excluding the distal interphalangeal joints, which are more commonly affected in osteoarthritis.
