Hepatitis G virus (HGV) infection in Saudi dialysis patients and healthy controls.
BACKGROUND
Viral hepatitis is a global health problem with a high mortality rate. End stage renal disease (ESRD) patients have a high prevalence of Hepatitis B and C virus infection. Present study was done to identify the prevalence and course of a new isolate Hepatitis G virus (HGV) infection in Saudi dialysis patients.


METHODS
The pattern of viral hepatitis infection (HBV. HCV and HGV) was investigated in 109 Saudi patients with ESRD and 100 healthy Saudi blood donors. Donated blood was tested for markers of Hepatitis B, C and G viruses. Liver functions were measured and blood picture and liver biopsies were also performed at regular intervals.


RESULTS
Out of the 109 ESRD patients 68 (62.4%) were positive for at least one viral marker: 59 (54.1%) were positive for HCV, six (5.5%) were positive for HGV and three (2.8%) were positive for HBsAg. Four of the six HGV positive patients were also co-infected with HCV. Eight (8%) of the blood donors were positive for at least one viral marker. Elevated ALT levels (>4 times normal) were recorded in four out of the six HGV-positive patients including three co-infected with HCV.


CONCLUSIONS
Our results are in agreement with similar studies from different countries and also raise the question about the causal relationship between HGV and liver disease among dialysis patients.
