Late-onset aspirin-related hemolysis and subsequent subdural hemorrhage in patient with glucose-6-phosphate dehydrogenase deficiency

Key Clinical MessageAspirin-related hemolysis in G6PD deficiency could be late-onset during long-term administration. Hemolytic anemia could continue for a relatively long time in elder patient with G6PD deficiency, which might be related to other adverse events.AbstractAspirin-related hemolysis in G6PD-deficient individuals was generally reported among patients who received high-dose supplements within several days after ingestion. The safety of long-term and low-dose (50-325 mg/day) aspirin in patients coexist G6PD deficiency and cardiovascular disease is neglected in clinical practice. In this case, we observed a late-onset hemolysis and subsequent fatal subdural hemorrhage in one G6PD-deficient individual who had received long-term and low-dose aspirin. An 83-year-old male was diagnosed with acute ischemic stroke and treated with 100 mg/day aspirin at the emergency room. After admission, the patient was diagnosed with severe G6PD deficiency based on enzyme activity, but no hemolysis occurred within 10-day aspirin therapy in the hospital. Hence, 100 mg/day aspirin was continued on discharge. Two months later, the patient presented acute hemolysis manifested as fatigue, dark urine, and moderate jaundice. Although hemolysis was self-limit in a few days, hemoglobin decline continued for 20 days until a fatal subdural hemorrhage occurred. Our study indicated aspirin-related hemolysis could be late-onset in G6PD-deficient individual even receiving low-dose treatment and is probably linked to subsequent major bleeding events.
