title: Chronic childhood idiopathic thrombocytopenic purpura.
abstract: Childhood idiopathic thrombocytopenic purpura (ITP) is a largely trivial disorder from which over 95% of children sooner or later recover spontaneously, and for most of whom the risks of unnecessary or ineffective therapy are arguably greater than those of the untreated disease. There are, however, a few patients who continue to have very low platelet counts and remain symptomatic for many months or years. They are rare, and they present difficult management problems. Splenectomy is probably the most effective treatment but is also the most dangerous and is not always successful. It is also irreversible. Most other regimens are either ineffective, unacceptably toxic, or both. Planning management for an individual patient requires a realistic risk:benefit appraisal, a process that is impeded by inadequate epidemiological data and a scarcity of large-scale randomized clinical trials. International collaborative studies may help in the future.
