Abstract
Background
Glucose 6 phosphate dehydrogenase deficiency (G6PDd) is the most common enzyme deficiency in humans. Randomized clinical trials comparing the efficacy of different types of fluid therapy for prevention of acute kidney injury (AKI) following hemolysis in patients with G6PDd are lacking. The present study aimed to compare the efficacy of three different types of fluid administration, isotonic saline with or without acetazolamide versus bicarbonate solution in prevention of AKI among children with acute hemolysis due to G6PDd.
Methods
In this double-blind randomized controlled clinical trial, 120 infants and children with acute hemolysis due to G6PDd were randomly divided into three groups consisting of 40 participants in each group. Group A received normal saline. Group B received normal saline plus oral acetazolamide at a dose of 5 mg/kg/day, and group C received half saline plus 75 mEq/L sodium bicarbonate. The primary outcome of this study was the frequency of AKI among the different types of fluid administration.
Results
In this study, 72 (60%) patients were boys with the mean age and length of hospital stay of 3.9 ± 2.2 years and 54.4 ± 29.9 h, respectively. AKI as the primary outcome of this study occurred only in one patient in group C and the rate of AKI did not differ significantly among patients receiving different types of fluid resuscitation (P > 0.05).
Conclusion
Normal saline was equivalent to fluids containing alkalinizing agents in preventing heme-induced nephropathy in patients with G6PDd.
