Background: Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Although occult HCV infection is less aggressive than classic chronic HCV infection, nevertheless it is important in management of hemodialysis (HD) patients. Occult HCV infection has been described in two different clinical settings: in patients with normal liver enzymes or in patients with abnormal values of liver enzymes. The aim of this study was to detect the occult HCV infection in hemodialysis patients with elevated liver enzymes.

Materials and Methods: This cross sectional study was performed in hemodialysis patients referring to 3 dialysis units in Tehran. In 30 anti-HCV negative HD patients with elevated liver enzymes, presence of HCV-RNA in plasma samples was tested by Reverse Transcriptase-Nested Polymerase Chain Reaction (RT-nested PCR). In cases with negative anti-HCV and plasma HCV-RNA, HCV-RNA was checked in PBMC specimens by RT-nested PCR.

Results: A total of 30 HD patients with mean age 54.4± 14.1years and mean dialysis duration 81.2 ±64.4 months were enrolled in the study. All HD subjects were negative for HCV-RNA in plasma and occult HCV infection with RT-nested PCR method.

Conclusion: Occult HCV infection was rare in HD patients with elevated levels of liver enzymes.
