Frequency of active HCV infection among anti-HCV positive patients in selected districts of Khyber Pakhtunkhwa, Pakistan
Journal Title: Journal of Microbiology and Infectious Diseases - Year 2013, Vol 3, Issue 4
Abstract
Objective: The objective of this study was to determine frequency of active HCV infection among confirmed anti-HCV positive subjects of KPK in order to help the infected subjects decide about anti-viral treatment options. Methods: Blood samples (3075 samples) were collected from patients in selected districts of KPK and were transported to Centre of Biotechnology and Microbiology, Diagnostic laboratory, University of Peshawar. These patients were already screened for anti-HCV by ICT (Immuno Chromatographic Technique) and ELISA (Enzyme Linked Immunosorbant Assay) in the local laboratories of the concern districts. Subsequently, viral RNA was isolated from serum sample and subjected to Real-time PCR. The frequency of the results was calculated for the HCV-RNA positive and negative samples. Results: Out of 3075 confirmed anti-HCV samples, HCV-RNA positive and negative samples were 2055 (66.6%) and 1020 (33.3%) respectively. The frequency of male and female HCV-RNA positive samples was 57.6% and 42.4% respectively. Rate of false anti-HCV positivity was 33.3%. Moreover, rate of active HCV infection was found more in district Bunir followed by districts Dir and Mardan. Comparatively less positive percent frequency of active HCV infection was found in districts Swabi, Peshawar and Kohat, respectively. Conclusion: It is concluded that viremia is present in more than 50% of confirmed anti-HCV positive patients. Anti-HCV positive, but HCV-RNA negative samples represent either false- positivity of anti-HCV or a spontaneous clearance of HCV.
