Id: 24736 Autor: Desforges, J. F; Thayer, W. W; Dawson, J. P Título: Hemolytic anemia induced by sulfoxone therapy, with investigations into the mechanisms of its production ?- Fonte: Boston; s.n; 1960. 5p p. ilus. Resumo: A case report is presented of a patient in whom clinical evidence of hemolytic anemia with methemoglobinemia developed upon increasing the dosage of sulfoxone which he was receiving for Hansen's disease. Administration of the drug was withdrawn for six weeks, after which studies were made with the use of radioactive iron to demosntrate the hemolytic effect of sulfoxone. By means of tagging cells of a single age group, it was shown that the suceptibility to hemolysis was related to cell age, and it was only after the red cells had been in the circulation for approximately fifty days that they were subject to the hemolytic effects of this drug. No significant biochemical defect could be demonstrated in the erythrocytes of this patient. However, the decline in activity of glucose-6-phosphate dehydrogenase and glutathione reductase in the aging red cell and the reported sensitivity to this drug of patients with red cell deficiency of glucose-6-phosphate dehydrogenase suggest that the hemolytic mechanism is related to this enzyme system. The case demonstrates that drug-induced hemolytic anemia of this type may occur without demonstrable enzymatic defect of the erythrocytes. The observation that patients appear to compensate for the hemolytic anemia and methemoglobinemia if maintained on this drug may be explained by the fact that the older cells containing less adequate enzyme systems are removed from the circulation and an equilibrium is maintained by increased production of red cells with a shorter age span.

Id: 17868 Autor: Kenner, D. J; Holt, K; Agnello, R; Chester, G. H Título: Permanent retinal damage following massive dapsone overdose ..- Fonte: s.l; s.n; oct. 1980. 4 p. ilus, graf. Resumo: A massive dose of 7.5 g of 4,4'-diamino, diphenyl sulphone (dapsone) taken as a suicide attempt in a patient on long-term therapy for tuberculoid leprosy resulted in permanent bilateral retinal necrosis, previously unreported side effect of this drug. The patient developed a severe haemolytic anaemia, methaemoglobinaemia, and acute renal failure requiring peritoneal dialysis. It is proposed that the retinal damage was due to a combination of severe hypoxaemia and the physical effects of red cell fragmentation producing vascular occlusion in the macular and perimacular region, with consequent ischaemic necrosis...(AU).
