[Autoimmune thrombocytopenic purpura. Clinical and therapeutic retrospective study of 544 cases (author's transl)].

A retrospective study of 544 patients with autoimmune thrombocytopenic purpura showed that 81 had immunological abnormalities (antinuclear factors and/or positive direct Coombs; test and/or anti-smooth muscle antibodies). After one year, 58-8% of all patients were still in complete remission, irrespective of treatment. The outcome of the disease was studied in relation to therapeutic regimens. Prognosis was worst in patients with immunological abnormalities, since 11% died as compared with 4% of the whole patient population. Most relapses occurred during the first two years following remission.
