Fulminant hemolysis in glucose-6-phosphate dehydrogenase deficiency.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked disorder affecting some 400 million people worldwide. Though clinically silent, it may result in hemolysis on oxidative stress induced by drugs or infections. Viral hepatitis A with coexisting G6PD deficiency can be devastating associated with severe hemolysis, anemia, renal failure, and hepatic encephalopathy.
