title: Acute intravascular haemolysis in glucose-6-phosphate dehydrogenase deficiency.
abstract: Thirty-five children with G6PD deficiency, who presented with acute intravascular haemolysis, were evaluated to define its aetiology, clinical features and ultimate outcome. All were boys with ages ranging from 6 months to 12 years. Pallor of abrupt onset and passage of cola-coloured urine were universal presenting symptoms. Incriminating factors responsible for haemolysis include hepatitis (7), malaria (4), bacterial sepsis (3) and drug intake (24), with more than one predisposing condition existing in some children. Marked elevations in serum bilirubin, coinciding with intravascular haemolysis, was a feature in all the seven children with hepatitis. Azotaemia was noted in 20 patients, of whom 14 did not have oliguria. All four children with malaria presented with protracted renal failure. Therapy focused on maintaining a high urine output in those without oliguria. A total of 15 peritoneal dialyses and five haemodialyses were required in six patients with acute renal failure, all of whom were oliguric. Supportive therapy consisted of blood transfusions and treatment of the predisposing diseases. Thirty-two children recovered completely while three died, the cause of death being severe anaemia and congestive cardiac failure, malaria with oliguric renal failure and hepatic encephalopathy, respectively.
