BACKGROUND: G6PD deficiency is the most common enzymopathy of red blood cells. 
The clinical symptoms of favism are jaundice, hematuria and haemolytic anaemia 
that seem to affect liver and kidney in long term. Thus we evaluate kidney and 
liver function of favism patients in an endemic area of the disease with a high 
rate of fava beans cultivation.
METHODS: This study was performed on favism patients and healthy controls 
referring to Iranshahr central hospital. Liver and kidney function tests were 
performed.
RESULTS: The results showed a statistically significant difference between these 
two groups (p <0.05) for liver function tests, (AST, ALT and ALP), but not for 
renal tests (BUN and creatinine) (p >0.05).
CONCLUSION: Due to abnormalities were seen in the liver function tests of these 
patients, we suggest that these tests be regularly performed for favism patients 
who are constantly exposed to oxidant agents.
