This study shows significant effects on parameters during Ramadan fasting such as anthropometric indices, fasting glucose, plasma insulin, and inflammatory cytokines in patients with NAFLD. The results of this study suggest that Ramadan fasting may be useful to improve NAFLD, so further studies are needed in this area.

Abstract. Background: Nonalcoholic fatty liver disease (NAFLD) is a serious global health problem, thus the prevention and management of the disease is necessary. This study aimed to determine the effects of Ramadan Fasting (RF) on liver function, Visceral Adiposity Index (VAI) and Atherogenic Index of Plasma (AIP) in these patients. Methods: Eighty-three NAFLD patients (57 males and 26 females) were enrolled in the study, 42 patients who practiced RF, between Jun 18 through July 17, 2015 and 41 patients in non-fasting groups. Anthropometric parameters and Ultrasound grading were measured before and after Ramadan. The biochemical parameters including lipid profiles (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides), liver enzymes (Aspartate aminotransferase, SGOT and Alanine aminotransferase, SGPT) were evaluated before and after Ramadan. AIP and VAI were calculated based on formula. Results: The mean decreases in anthropometric indices were significantly different between groups. Similarly, the mean decrease in the total cholesterol values in the fasting group was remarkably greater than in the control group (p = 0.02). The values of AIP and VAI decreased at the end of the study in both group and the mean of changes showed no differences between groups (p = 0.79 and p = 0.65 for AIP and VAI, respectively). The changes in the concentrations of liver enzymes, as well as the severity of hepatic steatosis, showed remarkable differences between groups (p = 0.03, p = 0.05, and p = 0.02 for SGOT and SGPT, and Liver steatosis, respectively). Conclusion: RF improved liver steatosis in NAFLD patients and might be useful in the management of NAFLD.

SummaryBackgroundNon-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of insulin resistance, is the most common cause of chronic liver. The present study aimed to investigate the roles of vaspin and omentin-1 in the NAFLD-related pathology including IR, inflammation and elevated blood pressure.MethodsThis cross-sectional study was conducted among 83 NAFLD patients in Jahrom, Iran. Plasma levels of omentin-1, vaspin, hs-CRP and IL-6 were measured. Anthropometric indices, lipid profiles, liver enzymes as well as abdominal ultrasonography were assessed.ResultsPartial correlations controlling for age and sex showed significant positive correlation between vaspin and fasting blood sugar (FBS), insulin, HOMA-IR, and hs-CRP. It has been observed that omentin negatively correlated with glucose levels. Moreover, a marginally significant association has been found between omentin levels and systolic blood pressure (SBP).ConclusionsThis study shows that vaspin and omentin-1 are associated with inflammation, insulin resistance and serum glucose levels in patients with NAFLD.
