Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect. Screening for this condition in HIV-infected patients from susceptible ethnic groups is recommended based on expert opinion. Here we determined the prevalence of G6PD deficiency and the occurrence of G6PD-related hemolytic events in a large cohort of patients.


We identified all HIV-infected adults who presented as new patients at a single urban HIV clinic between 02/01/2007 and 01/31/2009. Demographic and laboratory data including G6PD results were collected. In addition, outpatient and inpatient medical records of G6PD deficient patients were reviewed for episodes of hemolytic anemia.


A total of 1172 patients were identified and G6PD testing was performed in 1110 (94.7%). Overall, 75 (6.8%) subjects had G6PD deficiency. Rates were higher among African Americans (68/699; 9.7%) and Hispanics (5/253; 2.0%). Only one non-Hispanic White subject had G6PD deficiency (1/153; 0.7%). At baseline, hemoglobin concentrations were similar among subjects with or without G6PD deficiency. Among patients with G6PD deficiency, 40 (53.3%) were prescribed trimethoprim-sulfamethoxazole or dapsone. During follow-up, five (6.7%) of these patients developed acute hemolytic anemia.


These results provide strong clinical evidence for recommending G6PD testing in HIV-infected subjects from susceptible ethnic backgrounds.
