The clinical course of immune thrombocytopenic purpura in children who did not receive intravenous immunoglobulins or sustained prednisone treatment

OBJECTIVE: To demonstrate the result of watchful waiting without specific therapy in unselected children with acute immune thrombocytopenic purpura (ITP). STUDY DESIGN: Between May 1992 and October 1999, 55 consecutive children (aged 2 months to 16 years; 28 boys and 27 girls) with acute ITP did not receive intravenously administered immune globulin G (IVIG) or sustained prednisone treatment. Patients with extensive mucosal bleeding were given prednisone, 2 mg/kg/d, for 3 days. RESULTS: In 37 of 55 patients the initial platelet count was <10,000/microL. Ten of these patients had active mucosal bleeding. Five additional patients with bleeding had platelet counts between 10,000 and 20,000/microL. Four patients were given a 3-day course of prednisone. Chronic ITP occurred in 7 (13%) of the patients; 29 patients achieved remission within 6 weeks, and 19 patients, between 6 weeks and 6 months. No life-threatening bleeding occurred, and no patient died. CONCLUSION: Most children with severe thrombocytopenia do not have active mucosal bleeding. This management approach, which did not administer specific therapy, avoided side effects, reduced cost, and was effective.
