The relation between nonalcoholic steatohepatitis and iron metabolism is still controversial. Free fatty acids, iron, and other sources of oxidative stress probably result in cell damage, and necroinflammation mediated by various cytokines.


Sixty patients were diagnosed with NASH were included in the study, and the patient group was divided into three subgroups. Iron metabolism markers, inflammatory cytokines, including TNF-α, IL-6 and IL-8, MDA and nitric oxide levels were measured.


Serum ferritin, inflammatory cytokines, and oxidative stress markers were significantly higher in the patient group. Among three patient groups, divided according to the results of ultrasonic examination, there were significant changes with regard to these parameters.


The study results suggest that liver iron and fat accumulation, oxidant stres, and inflammatory cytokines are closely related. Therefore, levels of serum ferritin, MDA, IL-6, TNF-α and IL-8 could represent the indices of activity and progression of NASH.
