This study aim is to assess the prevalence of occult HCV infection among Egyptian patients with non alcoholic fatty liver disease (NAFLD) with elevated AST and ALT, and to correlate presence of occult HCV with severity of liver disease. Patients and Methods: After informed consent 27 patients with elevateed liver enzymes diagnosed as NAFLD were examined for demographic, clinical, laboratory data and Ultrasonography. Liver biopsy was done and tested for HCV RNA in tissue. Genotyping using RFLP analysis of PCR products in the 5’NCR was done for positive cases. Results: HCV RNA in tissue was positive in 11/27 patients (40.7%); genotype was 4a in all positive cases. AST and ALT values showed significantly lower values in occult HCV than the non HCV NAFLD group. Liver biopsy of studied patients showed no significant difference as regard inflammation and fibrosis according to METAVIR score. Conclusions: Occult HCV is highly prevalent among Egyptian NAFLD patients. It seems to induce a mild liver disease. Patients with elevated ALT and negative HCV RNA in sera might be investigated for tissue HCV RNA. Follow up is recommended for the occult HCV patients to monitor progression to overt disease.
