[Idiopathic thrombocytopenic purpura: long-term outcome]. / Purpura thrombopénique idiopathique chez 87 enfants: évolution à long terme.

ABSTRACT

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) has usually an excellent prognosis even when no specific therapy is given. We studied, in 1996, the outcome of 87 patients with ITP observed between 1973 and 1995. PATIENTS AND METHODS: These 87 cases represented all the thrombocytopenic purpura observed during 23 years in the same pediatric unit not specialized in hematology. The outcome of these children was investigated in 1996 by phone or writing to the patients themselves or to their physician. Adequate information was obtained for 63 patients (72.4%). RESULTS: Two cerebral hemorrhages were observed, one was lethal while the other, observed after several years of course, healed completely. All these patients became free from clinical signs but 11 were not cured in 1996. None of these 63 patients had developed autoimmune disease. One patient died in a traffic accident, his thrombocytopenic purpura had been cured. CONCLUSION: In spite of two cerebral hemorrhages, ITP remains in the great majority of cases a benign disease not requiring grave therapeutic decisions.
