Prevalence of hepatitis G virus (HGV) among hepatitis-B patients and others suspected for PT- hepatitis in Baghdad

The aim of this research is to evaluate the prevalence of hgv among three different categories, group1, composed of hepatitis –b patients (hb- patients), group 2, included people having hepatitis-like symptoms with sera negative for hbv and hcv markers, referred to as suspected for hepatitis (sus-patients) while the third group is the control group. serum samples were assayed for anti-hgv antibodies using elisa technique-indirect method. results revealed that hgv coinfection detected in only few number of hb-p 9.8%, 23.5% of hb-p having anti-hgv antibodies with titer lower than the cut-off value (cov) which are said to be in the shadow zone and the other 66.6% of the group are reported as negative cases, reporting a highly significant difference p˂0.001. among the second group (sus- patients), hgv was detected in only 4.8%, 58.5% detected as shadow cases while the other 36.5% were found to be negative for hgv.when both hb-p and sus-p are gathered in one group a low percentage 7.6% of hgv infection was recorded, 39.1% of hb-/sus-patients were in the shadow zone while the majority of this group 53.2% were detected as negative cases. in conclusion hgv play only a minor role as a confection agent with hbv and as a responsible agent among non-a-e hepatitis cases. remarkable high percentages of shadow cases are reported in the three groups especially among non-a-e hepatitis patients.
