RESUMO
Immune thrombocytopenia is a benign and self-limiting disorder. Data about the condition and its incidence from low-income countries is limited. This paper reviews the research about immune thrombocytopenia, comparing low- and high-income countries. Diagnosis is usually based on complete blood count and peripheral smear and, in selected cases, bone marrow aspiration. The disease has a high remission rate both in high- and low-income countries and intracranial haemorrhage is rare. The recommended treatment is simply observation of cases, especially when the platelet count is > 10 000 /mm[3]. If drug therapy is required, oral steroids are the most economical choice

We report the results of allogeneic bone marrow transplantation in 26 female and 37 male patients with beta-thalassaemia major [age range: 2-17 years], performed at Namazi Hospital over the period 1992-99. In all cases, standard conditioning and immunosuppressive regimens were employed. Currently, 50 patients remain thalassaemia-free, 9 of whom have developed chronic graft-versus-host disease. There were 8 deaths among the 13 unsuccessful transplant cases: 4 due to acute uncontrollable graft-versus-host disease, and 4 to non-transplant-related causes such as hypoglycaemia, hypersensitivity reactions and advanced disease. We conclude that allogeneic bone marrow transplantation is an effective therapy for the treatment of beta-thalassaemia major, particularly for patients classified as classes I and II
