Glucose 6 phosphate dehydrogenase deficiency: A single-center experience

OBJECTIVE: This study aims to evaluate the demographic information, clinical and laboratory findings of patients with glucose 6 phosphate dehydrogenase deficiency. MATERIAL AND METHODS: We collected data by reviewing files and electronic records of 65 patients with glucose 6 phosphate dehydrogenase deficiency under the age of 18 years who were followed up in our clinic between 2007 and 2019. Demographic, clinical, and laboratory features, family history, complications of the disease, and history of splenectomy and cholecystectomy were evaluated. Mean, standard deviation, and median values were used when descriptive analyses were presented. RESULTS: The age of diagnosis ranged between 1–192 months and the median age of diagnosis was two months. Fifty-nine patients (90.7%) were boys and six (9.2%) were girls. The mean value of glucose 6 phosphate dehydrogenase enzyme on admission was 1,9±1,4 U/g of hemoglobin (Hb). Family history was pesent in 40% of patients in whom information was avaliable. The most common presentation was prolonged jaundice and the most common physical finding was jaundice. Splenomegaly was detected in none of the patients. Cholelithiasis was present in one of 21 patients who were evaluated with ultrasonography. None of the patients required splenectomy, cholecystectomy, and regular erythrocyte transfusion during follow-up. CONCLUSION: As G6PD variants with chronic hemolysis are not usually seen in Turkey, patients who required splenectomy, cholecystectomy, and regular erythrocyte transfusion were not detected. Although glucose 6 phosphate dehydrogenase deficiency is more common in males, it can also be seen in girls. In Turkey, glucose 6 phosphate dehydrogenase deficiency should be considered in patients presenting with prolonged jaundice.
