C. Gout 
D. Muscular dystrophy 
E. Systemic Lupus Erythematosus (SLE) 
Choose the most appropriate answer from the options given below:     (NEET 2024)

Detailed Solution for 31 Years NEET Previous Year Questions: Health & Disease - 1 - Question 3

Autoimmune disorders are conditions in which the immune system mistakenly attacks the body's own tissues. Analysis of the given diseases in the context of autoimmune disorders includes:
Myasthenia gravis: This is an autoimmune disorder where antibodies interfere with the communication between nerves and muscles, leading to muscle weakness.
Rheumatoid arthritis: Another autoimmune disease where the immune system mistakenly attacks the lining of the joints, causing inflammation and potentially leading to joint deformity.
Gout: This is not an autoimmune disease; it's a form of arthritis caused by excess uric acid in the bloodstream, resulting in the formation of crystals in joints, not by immune system activity attacking body tissues.
Muscular dystrophy: This refers to a group of genetic diseases characterized by progressive weakness and loss of muscle mass, not caused by an autoimmune response.
Systemic Lupus Erythematosus (SLE): It is an autoimmune disease in which the immune system attacks various body systems including skin, joints, and organs like kidneys and heart.
With this analysis, the correct diseases identified as autoimmune disorders are Myasthenia gravis, Rheumatoid arthritis, and Systemic Lupus Erythematosus (SLE). Therefore, among the provided options, the correct answer is: Option B: A, B & E only.
