title: The relationship between resistin and ghrelin levels with fibrosis in nonalcoholic fatty liver disease.
abstract: BACKGROUND
  Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease. It is generally accepted that insulin resistance is a pathophysiological factor in the development of NAFLD. In the present study, the aim was to determine the relationship between resistin and ghrelin levels, which were found to be closely related to insulin resistance and fibrosis scores in NAFLD.
  
  
  METHODS
  A total of 40 (21 male, 19 female) NAFLD patients whose diagnosis was confirmed with biopsy and 40 (18 male, 22 female) healthy controls were included in the study.
  
  
  RESULTS
  In the comparison of resistin and ghrelin levels, only resistin values were found to be significantly higher in NAFLD group while there was no significant difference in ghrelin values (respectively P < 0.05; P = 0.078). In according to the fibrosis groups there was no difference about fasting plasma glucose, insulin values, Homeostatic Measurement Assessment-Insulin Resistance measurements and also resistin and ghrelin levels.
  
  
  CONCLUSIONS
  It has been understood that insulin resistance plays an important part in NAFLD. Larger studies are required that investigate the gene expression of hormones influencing insulin resistance, particularly resistin and ghrelin in order to determine their role in NAFLD.
