[Post-hemolytic renal failure in children with glucose-6-phosphate dehydrogenase deficiency at the University Hospital Center in Lome]

Abstract

The purpose of the study was to identify predisposing factors for acute hemolysis and post-hemolytic renal failure in children with glucose-6-phosphate dehydrogenase deficiency (G6PD). Any child presenting hemoglobinuria during the study period was prospectively evaluated. Evaluation included detection of the presence of hemolytic agents, laboratory tests to measure hemolysis, G6PD activity, infection and renal failure, and assessment of outcome and management of hemolysis and renal failure. G6PD deficiency was documented in 32.1% of the 230 children admitted with hemoglobinuria. Anuric renal failure occurred during the hemolysis episode in 35.1% of patients with G6PD deficiency (21 boys and 5 girls between 30 months to 13 years old). Acute hemolysis associated with infection occurred before any treatment in 53.8% of cases and after beginning treatment in 46.1%. In 84.6% of cases, occurrence of acute hemolysis involved association of drugs considered as nonhemolytic either with themselves or with other drugs. Anuric renal failure occurred after beginning treatment in all cases and was most severe in patients with of multiple-germ infection (30.7%) and drug association (84.6%). Renal failure was reversible in 80.7% and fatal in 19.2%. Multiple-germ infection and drug association appeared as the main predisposing factors for post hemolytic anuric renal failure in patients with G6PD deficiency. The high frequency of these factors in tropical areas suggests implication of local endemic infections.
