Correlation between Serum Ferritin Level and Histopathological Disease Severity in Non-alcoholic Fatty Liver Disease.

BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. Recently several parameters, such as serum ferritin, have emerged as possible predictors for the severity of NAFLD and insulin sensitivity. We aimed to investigate the value of serum ferritin level as a useful biomarker for the prediction of histopathological disease severity in non-alcoholic steatohepatitis (NASH), the necro-inflammatory form of NAFLD. METHODS This was a prospective cross sectional study in which demographic, clinical, histological, laboratory, and anthropometric data of 30 adult patients with biopsy-proven NAFLD/NASH were analyzed. RESULTS In our patients population with mean age of 37.9 years and mean BMI of 26.5, statistical analysis did not show a significant difference between the three grades of steatosis in the mean ferritin levels ( p = 0.559). It was also observed that ferritin level did not have a significant correlation with the stage of fibrosis ( p = 0.228). The mean transferrin saturation did not show significant difference in different stages and grades of NASH ( p = 0.260 and 0.944, respectively), either. CONCLUSION Serum ferritin level may not be useful as a single marker for the prediction of histopathological severity of disease in young patients with NASH who are not morbidly obese.
