Glucose-6-phosphate Dehydrogenase Deficiency And Sickle Cell Disease In Brazil

The frequency of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency was determined in 54 male patients with sickle cell diseases: 31 sickle cell anemia (SS), 14 sickle cell hemoglobinopathyc (SC) and 9 HbS/β-thalassemia (S/B-thal) by a combination of quantitative assay, fluorescent spot test and electrophoresis. Of the 54 patients tested, 7 were found to be G-6-PD deficient (G-6-PD-) (3 SS, 3 SC and 1 S/B-thal) and 47 G-6-PD normal (G-6-PD+) (6 G-6-PD A and 41 G-6-PD B). All the deficient patients were G-6-PD A-. The frequency of G-6-PD deficiency did not differ significantly from that observed in the general population. Compared to patients who were not G-6-PD-, there were no significant differences in the hemoglobin concentration and reticulocyte count in patients with sickle cell diseases who were G-6-PD-.42212512
