Chronic idiopathic thrombocytopenic purpura (ITP) in adult Ethiopians: clinical findings and response to therapy.
Between January 1982 and December 1989, thirty four cases of chronic idiopathic thrombocytopenic purpura (ITP) were seen in adult Ethiopians in the Department of Internal Medicine in-patient and haematology referral clinic, of Tikur Anbessa teaching hospital. Twenty three were females and eleven males; female to male ratio of 2.1:1. The age range was 13-57 years, with a mean of 24.9 years. The commonest manifestations were: purpura, epistaxis, gum-bleeding and menorrhagia. The duration of symptoms ranged from one month to over ten years (median 4.5 months). The platelet counts ranged from 4000/mm3 to 77,000/mm3 (mean - 19,200/mm3), haemoglobin 3.01 to 15.4 gm/dl (mean - 8.2 gm/dl). Four (11.8%) patients were not treated; of these, one went into spontaneous remission. Thirty patients (88.2%) were treated with prednisolone 1.0 to 1.5 mg/kg/day orally. Of these, 7 (23.3%) had excellent, 2 (6.7%) good, 6 (20%) fair, and 15 (50%) had poor responses. Ten patients had splenectomy with 5 (50%) excellent 2 (20%) good, 2 (20%) fair and 1 (10%) poor response. One patient with refractory ITP was treated with immunosuppressive drugs and had an excellent response. Fifteen patients are alive and on followup 3-122 months (median 33 months) after diagnosis, fifteen are lost after followup of 1-66 months (median 9 months) and four have died 1-18 months (median 2 months) after diagnosis. Chronic ITP is frequently seen in adult Ethiopians, its clinical features and response to therapy are similar to those reported in the literature.
