Introduction: Hepatitis G virus (HGV) infection appears to be common in patients with chronic hepatitis C virus (HCV) infection. The aim of this study was to investigate the prevalence of HCV/HGV in patients with chronic hepatitis C (CHC) in Pakistan and to look for possible associations with various clinical and histopathological changes in HCV/HGV coinfection and HCV infection.
Patients and methods: The present study included 136 patients. Clinical, biochemical, virological and histological findings were compared between patients coinfected with HCV/HGV and patients with HCV alone.
Results: Of the 136 patients with CHC, 16 (11.76%) were coinfected with HCV/HGV. The mean age of coinfected patients was lower than in patients with HCV alone. HCV/HGV coinfected patients did not show significant differences in sex, clinical presentation, biochemical markers, and liver fibrosis as compared to those with HCV infection. Only the mean values of platelets count, mean corpuscular hemoglobin (MCH), and MCH concentration markers were significantly different in HCV/HGV coinfected patients as compare to patients with HCV alone.
Conclusion: It was found that 11.76% of patients with CHC in Pakistan were associated with HCV/HGV coinfection. No significant differences were observed in clinical and histological features except for platelets count, MCH, and MCH concentration markers between HCV and HGV coinfected patients in comparison with HCV-infected patients.
