AB The prevalence and the characteristics of hepatitis C virus infection
(HCV) in 161 HIV-positive patients were studied. HCV seroprevalence was
determined by enzyme immunoassay and recombinant immunoblot assay
(RIBA). Two different reverse transcriptase polymerase chain reaction
(RT-PCR) methods were also used to test the HCV-seropositive samples and
50 EIA-negative sera used as controls. The RNA HCV-positive sera were
genotyped by the LiPA procedure. Associations of HCV status with
demographic characteristics and risk factors were assessed by chi 2 and
Fisher's exact tests. The seroprevalence of HCV was 34.2% with a
significant difference between blood and sexual exposure risk groups
(60.6% vs. 13.6%, respectively; P < 0.0001). Thirty-six of the 55
anti-HCV-positive sera were also positive for HCV RNA, and PCR detected
HCV RNA in 8 HCV-seronegative patients. Various RIBA profiles were found
and all sera were positive for antibodies to the c33 protein. A
proportion of sera had elevated levels of transaminase activity (37.2%),
and abnormal liver function as associated with HCV infection. Forty-two
samples were genotyped and five genotypes and subtypes of the HCV virus
were detected. Genotype 1a was the most frequent in this cohort,
although genotype 1b is generally more common in France. The majority
(94.1%) of the patients with genotype 1a had a history of blood
exposure, which may account for the difference.
