Which statement best describes acute ITP?

• A. Remission usually happens within several weeks
• B. Primarily affects elderly men
• C. Causes increased platelet production
• D. It never resolves spontaneously

Answer: (B)

Acute ITP is typically a self-limited immune destruction of platelets that mainly affects children after a recent infection. The defining point is that most pediatric cases resolve on their own, with platelet counts returning to normal within a few weeks to a couple of months without ongoing treatment. That’s why the statement about remission within several weeks best describes acute ITP. In adults, the disease is more likely to become chronic, and it’s not confined to elderly men. The marrow often shows increased megakaryocytes as production ramps up to compensate for peripheral destruction, so platelet production is indeed increased, but the hallmark course for acute cases—especially in kids—is spontaneous remission within weeks.
