BACKGROUND AND OBJECTIVES: Liver steatosis in chronic hepatitis C (CHC) is related to viral and metabolic factors and likely to genetic factors. The aim of this study was to know if hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR)-C677T polymorphisms are associated with liver steatosis in nonalcoholic patients with CHC.
PATIENTS AND METHOD: In 54 consecutive patients with CHC, alcohol consumption less than 40g/week, and no other causes of liver disease, a liver biopsy was performed. All variables were obtained at the time of biopsy. MTHFR-C677T was also performed in 128 healthy subjects, with age and gender similar to the patients.
RESULTS: Liver steatosis was found in 33 patients (61%), 30 of them having a mild degree. Hyperhomocysteinemia was more prevalent in patients with steatosis (61% vs 24%; p=0.008) and overweight tended to be more prevalent in the same patients (61% vs 33%; p=0.05). All patients with virus C genotype 3 had steatosis. Viral load, liver inflammatory and fibrosis score were not different in patients with and without steatosis. MTHFR-C677T polymorphism was similar in controls and cases and in cases with and without steatosis. A multiple logistic regression showed that hyperhomocysteinemia was associated with liver steatosis after adjustment for age and sex (OR: 3.94; 95% CI: 1.09-14.29), and adjustment for overweight (OR: 4.43; 95% CI: 1.27-15.51).
CONCLUSIONS: In nonalcoholic patients with CHC mild liver steatosis is frequent, and is associated with hyperhomocysteinemia. An association between steatosis and MTHFR-C677T polymorphism was not found.
