BACKGROUND: Hyperuricemia is associated with non-alcoholic fatty liver disease (NAFLD).
AIM: We therefore aimed at evaluating the influence of allopurinol on the course of NAFLD in rats.
STUDY DESIGN: We divided 21 mature albino Sprague Dawley rats into three groups: controls (n = 7, normal diet for 12 weeks); NAFLD rat models (by feeding water containing 30% fructose for first 8 weeks) treated with allopurinol subsequently for the next 4 weeks (n = 7); and similar case treated with placebo (saline) subsequently for the next 4 weeks (n = 7).
METHODS: We compared the histopathological scores, IL-1 and IL-2 immunoexpression levels across the groups. Liver histopathological score was determined by observing the steatosis (the percentage of liver cells containing fat): <25% = 1+, 25% - 50% = 2+, 51% - 75% = 3+, >75% = 4+; inflammation and necrosis: 1 focus per low-power field = 1+; and 2 or more foci = 2+. The number of liver IL-1 and IL-2 positive cells was measured by systematically scoring at least 100 hepatocyte cells per field in 10 fields of tissue sections by a magnification of 100.
RESULTS: Xanthine oxidase (XO) activity and lipid peroxidation was significantly different in the allopurinol group compared to the saline group (XO; 0.098 ± 0.006 mU/mg vs. 0.162 ± 0.008 mU/mg, p = 0.01, 0.116 ± 0.040 nmol malondialdehyde/mg versus 0.246 ± 0.040 nmol malondialdehyde /mg, p = 0.01). The allopurinol group had lower histopathological scores, IL-1 and IL-2 immunoexpression levels in the liver compared to the saline group (2.13 ± 0.35 against 5.45 ± 0.24, p = 0.003, IL-1; 5.76 ± 0.43 against 12.85 ± 3.26, p = 0.023, IL-2; 8.55 ± 1.14 against 56.23 ± 7.12, p = 0.002).
CONCLUSIONS: Allopurinol has a therapeutic role against the progression of NAFLD of the rats.
