Which autoimmune disease is also known as Poly-Arthritis?

• A. Osteoarthritis
• B. Rheumatoid Arthritis or Poly-Arthritis
• C. Osteoporosis
• D. Tendonitis

Answer: (B)

Rheumatoid arthritis is an autoimmune inflammatory joint disease that commonly presents as polyarthritis, meaning inflammation in multiple joints. This pattern—involvement of several joints, often symmetrically and affecting small joints of the hands and feet—fits the description of an autoimmune condition manifesting as widespread joint inflammation. The other options describe conditions that are not autoimmune or do not characteristically involve multiple joints: osteoarthritis is a degenerative wear-and-tear disease, osteoporosis is a bone-density problem, and tendonitis is inflammation of a tendon. So the autoimmune, multi-joint inflammatory nature makes rheumatoid arthritis the correct label for Poly-Arthritis.
