Abstract

Abstract:  We studied the general outcome in 94 adult patients with autoimmune thrombocytopenic purpura (ATP) submitted to splenectomy. Of 84/94 patients who presented a complete or partial response 30 d after splenectomy, 16 (19%) showed one or more relapses. The clinical situation of the 81 patients still under observation is as follows: 13 unrensponsive, 60 completely or partially responsive, without relapses during the follow-up, 8 completely or partially responsive after one or more relapses. No correlation was found between the favourable splenectomy outcome and age at splenectomy, the diagnosis-splenectomy interval and initial response to corticosteroids. The probability of disease-free survival is 83%, projected at 10 yr, while the overall survival is 93%, projected at 10 yr.

PAIgG levels of the normal subjects and of responding patients were found to be similar, while in the groups of non-responding/relapsing patients, significantly higher values of PAIgG were detected, as compared to the control group.
