Question

Which of the following are Autoimmune disorders?
A. Myasthenia gravis
B. Rheumatoid arthritis
C. Gout
D. Muscular dystrophy
E. Systemic Lupus Erythematosus (SLE)
Choose the most appropriate answer from the options given below:

• A. A, B & D only
• B. A, B & E only
• C. B, C & E only
• D. C, D & E only

Answer 1

The Correct Option is B

To determine which of the given options are autoimmune disorders, let's explore each condition:

• Myasthenia gravis: It is an autoimmune disorder where antibodies block or destroy muscle receptor sites, leading to muscle weakness.
• Rheumatoid arthritis: This is an autoimmune condition in which the immune system attacks the synovium (lining of the membranes that surround the joints), causing inflammation and joint damage.
• Gout: This condition is caused by the accumulation of urate crystals in the joints due to high levels of uric acid. It is not an autoimmune disease.
• Muscular dystrophy: A group of genetic diseases causing muscle weakness, not autoimmune in nature.
• Systemic Lupus Erythematosus (SLE): This is a chronic autoimmune disease affecting multiple systems of the body, leading to inflammation and tissue damage.

Based on this information, the autoimmune disorders among the options are:

• A. Myasthenia gravis
• B. Rheumatoid arthritis
• E. Systemic Lupus Erythematosus (SLE)

Thus, the correct answer is: A, B & E only.

Answer 2

Myasthenia gravis, Rheumatoid arthritis, and Systemic Lupus Erythematosus (SLE) are all autoimmune disorders, where the immune system attacks the body’s own tissues.

Gout is not an autoimmune disorder; it is caused by the accumulation of uric acid crystals.

Muscular dystrophy is a genetic disorder, not autoimmune.

Thus, the correct answer is (2) A, B, E only.
