Abstract:

Exposure to hepatitis C virus (HCV), hepatitis G virus (HGV) and the carrier 'rate' for hepatitis B virus (HBsAg) were investigated in thalassaemia patients in Lebanon, a group that has not been studied in the past. The HCV genotypes and their distribution in the 395 thalassaemics, all of whom had been registered at the Chronic Care Center (CCC) in Hazmieh since 1996, were also studied. Of the 55 samples (14%) found positive for anti-HCV, 19 were also positive for HCV RNA. The 19 samples of HCV RNA were mostly of genotype 4 (37%), followed by 1a and 3a (21% each), 1b (16%) and 2b (5%). Most (14; 74%) of the 19 HCV-RNA-positive samples, but only 13 (36%) of the 36 samples that were negative for HCV RNA although anti-HCV-positive, were positive for anti-HGV. Among 100 anti-HCV-negative samples, eight (8%) were anti-HGV positive. Only one (0.28%) of all 395 patients investigated was found to be HBsAg-positive. All of the HBV- and HCV-positive patients had initially been found positive in 1996, when they were first registered at the CCC, and none of the remaining patients had seroconverted since. As none of the patients had been checked for anti-HGV until the present study, the history of their exposure to HGV was unknown.

These results emphasise the importance of screening all blood donations collected in Lebanon for HBsAg and anti-HCV. This and stringent infection-control measures are necessary steps to limit the spread of HBV, HCV and perhaps HGV to thalassaemics.
