Nosocomial transmission of hepatitis C virus in haemodialysis patients.
A systematic virological follow-up of 114 haemodialysis patients treated in the same unit showed that 37, including 17 PCR positive patients, were seropositive for hepatitis C virus (HCV).
Type 1b HCV was detected in 10 patients and was much more frequent in this population than in the whole population of patients treated in the hepatogastroenterology departments in southeastern France.
The E1/E2 genomic region of seven type 1b HCV strains was sequenced.
In four patients, a similar strain was detected in both the E1 variable region and the E2 hypervariable region (HVR1).
In addition, two of these four patients were seronegative and PCR negative at the beginning of the study and had not been transfused or transplanted during this period.
A phylogenetic tree was drawn which confirmed that these strains were very similar and showed that HCV was transmitted via the nosocomial pathway in this haemodialysis unit.
