Abstract
Out of 20 patients with viral hepatitis whose glucose-6-phosphate dehydrogenase (G-6-PD) levels were normal, 14 had clinical evidence of a mild to moderate degree of haemolysis but in all the patients studied the half life of chromium-51-labelled red cells was shortened. Out of 18 viral hepatitis patients deficient in G-6-PD 17 had clinical evidence of haemolysis, and in eight this was more severe than in the group with normal G-6-PD values. Massive intravascular haemolysis occurred in four, three of whom died. The massive haemolysis was attributed to the presence of additional drug-induced oxidative stress to the G-6-PD-deficient red cells.
