Prevalence and clinical expression of HCV-genotypes in haemodialysis-patients of two geographically remote countries : Belgium and Saudi-Arabia.
Hepatitis C virus is the leading cause of acute and chronic liver disease in hemodialysis patients.
There are at least six major HCV-genotypes, with a well documented geographical distribution in the general population.
Moreover, HCV-genotype is one of the major determinants of the therapeutic response to Interferon Alpha in affected patients.
Since the therapeutic outcome in HCV-positive hemodialysis patients, especially with regard to the different HCV-genotypes, is of interest, a multicentre epidemiologic study was performed in HCV-antibody positive hemodialysis patients of two geographically remote countries, i.e. in Flanders (Belgium) and in Saudi-Arabia. 184 chronic hemodialysis patients, with a positive second or third generation Elisa assay for HCV, were tested for HCV-viremia and HCV-genotype, using a 5'untranslated region (UR) nested PCR for the detection of HCV-RNA and subsequently type-specific probes to hybridize with HCV-RNA (Inno-Lipa).
Additionally, clinical data were collected by means of a standardized questionnaire, thoroughly completed by the nephrologist in charge of each respective patient.
Viremia was present in 79% of the patients (146 out of 184).
The prevalence of HCV-genotypes differed significantly between Belgian and Saudi-Arabian dialysis-patients.
In Belgian dialysis patients HCV-genotype 1b was most prevalent (i.e. (...)
