Detection of occult hepatitis C virus among healthy spouses of patients with HCV infection.

ABSTRACT

The criterion standard for the diagnosis of occult hepatitis C virus (HCV) infection is detection of HCV-RNA in liver cells. However, because of the invasive nature of liver biopsy, other methods have been studied. The present study aimed to identify subjects with occult HCV-4 infection among healthy sexual partners of patients with chronic HCV-4 infection by detecting HCV-RNA in peripheral blood mononuclear cells (PBMCs) using real-time polymerase chain reaction (PCR). Fifty healthy Egyptian spouses of patients with chronic HCV-4 infection were included in this study. Real-time PCR was used to detect HCV-RNA in PBMCs in all the study subjects. The prevalence of occult HCV-4 infection was 4%, and a statistically significant higher prevalence was found among patients with a history of sexually transmitted infection. The results of the present study indicate the importance of intra-spousal transmission of HCV-4 infection, especially in subjects with a history of sexually transmitted infection.
