Burden of HIV and hepatitis C co-infection: the changing epidemiology of hepatitis C in HIV-infected patients in France

Background & AimsTo better evaluate the HIV-HCV co-infection burden in the context of new effective HCV treatment. MethodsWe reviewed all the epidemiological data available on HCV-related disease in HIV-infected patients in France. Sources of data have been selected using the following criteria: (i) prospective cohorts or cross-sectional surveys; (ii) conducted at a national level; (iii) in the HIV-infected population; (iv) able to identify HCV co-infection and chronic active hepatitis C (HCV RNA positive); and (v) conducted during the period 2003-2012. ResultsThe overall prevalence of HIV-HCV co-infection has decreased from 22-24% to 16-18%. This prevalence decreased from 93% to 87% among injecting drug users while it increased from 4% to 6% among men who have sex with men. The characteristics of patients have changed: decrease in the proportion of patients with chronic active hepatitis C (HCV RNA positive) from 77% to 63% and in the genotypes 2 and 3 HCV infection; increase in the proportion of HCV genotype 1 (from 45-50% to 58%) and genotype 4 (from 15% to 22%). The proportion of patients treated with highly active antiretroviral therapy increased from 76% to 95%, with higher rates of undetectable HIV viral load (47% in 2004 vs. 85% in 2012). ConclusionThe decreasing prevalence and the change in patients profile in HIV-HCV co-infection underline the importance of continuing efforts to educate physicians and patients. This should increase the benefit of viral risk reduction policies and increase the access of co-infected patients to HCV treatment.
