ABSTRACT
Glucose 6 phosphate dehydrogenase (G6PD) deficiency is the most common disease producing enzymopathy. People with G6PD deficiency cannot cope with oxidative stressors. These patients are asymptomatic until they develop a haemolytic crisis which presents as anaemia and jaundice. The agents known to cause haemolysis in these patients are: oxidant drugs, (primaquine, chloroquine and other anti-malarials), antibiotics, (chloramphenicol, nitrofurantoin, sulphonamides, and all quinolone antibiotics). Chemicals to be avoided are moth balls (napththalene), aniline dyes, and some Chinese herbal medicine (San Chi, Chuan Lian). The classic presentation of exposure to Fava beans (legumes), causing oxidative haemolysis, has led G6PD deficiency to be also known as Favism. The patient we present here had no exposure to any of the known causes of oxidative haemolysis. Instead his precipitating cause strongly suggests raw fenugreek (T foenum-graecum L), a legume used as a herbal treatment for diabetes and previously not known to be a precipitant of haemolysis in G6PD deficiency.
