Anti-dsDNA antibodies are most commonly associated with which disease?

Anti-dsDNA antibodies are most commonly associated with which disease?

• A. Systemic sclerosis
• B. Rheumatoid arthritis
• C. Sjogren syndrome
• D. SLE

Answer: (D)

Anti-dsDNA antibodies are highly specific for systemic lupus erythematosus and are particularly associated with lupus nephritis, reflecting immune complex–mediated kidney involvement. Their presence strongly supports a lupus diagnosis when clinical features fit, whereas they are uncommon in systemic sclerosis, rheumatoid arthritis, or Sjogren’s syndrome. This makes systemic lupus erythematosus the disease most characteristically linked to anti-dsDNA antibodies.
