AB OBJECTIVE: To compare hepatitis C virus (HCV) load in patients infected
with HCV alone and those coinfected with HIV, and to evaluate the
antibody response to HCV in the case of HIV infection. DESIGN: Patients
coinfected with both HCV and HIV have been shown to develop hepatic
changes more rapidly, which may be due to an interaction between HCV and
HIV. In a prospective study, serum samples were taken from 150 patients.
METHODS: Using reverse transcription followed by polymerase chain
reaction and the branched DNA assay, we detected HCV RNA in 75 patients
coinfected with HIV and HCV and in 75 patients infected with HCV alone.
The HIV RNA was also quantified by the branched DNA assay and the p24
antigenaemia was determined by enzyme-linked immunosorbent assay. The
immune response to HCV was studied in the 150 patients by the use of
third generation recombinant immunoblot assay (RIBA). RESULTS: Although
a comparable number of patients had detectable HCV viraemia in both
groups, HCV RNA was quantifiable in 79% of HIV-positive patients and in
only 43% of HIV-negative patients (P < 10(-5)), and the mean HCV RNA
level was much higher in the HIV-positive group than in the HIV-negative
group (P < 10(-7)). The quantity of HCV RNA did not correlate with the
CD4 count, p24 antigenaemia or HIV RNA level. The analysis of RIBA
showed 14.7% indeterminate or negative results in the HIV-positive group
and only 4% indeterminate results in the HIV-negative group.
HIV-positive patients had reactivity to less antigen bands than
HIV-negative patients (P < 10(-3)), and they had a weaker reactivity to
c100, c33c and NS5 antigen bands than HIV-negative patients. CONCLUSION:
Our results show that in the case of HIV infection, the HCV RNA levels
are strongly increased, but HCV load is not linked to the
immunosuppression induced by HIV; therefore, the present data do not
support the hypothesis of a direct interaction between HIV and HCV.
