ObjectivesMany HIV-infected patients with chronic hepatitis C virus (HCV) infection do not receive treatment for HCV infection, often because of contraindications or poor adherence to anti-HIV therapy. The aim of this study was to identify factors influencing guideline-based HCV treatment initiation in a large cohort of HIV/HCV-coinfected patients.
MethodsBetween 2005 and 2011, 194 (40.5%) of 479 coinfected patients not previously treated for HCV infection started this treatment based on current recommendations, i.e. a Metavir score > F1 for liver fibrosis; HCV genotype 2 or 3 infection; or HCV genotype 1 or 4 infection and low HCV viral load (< 800 000 IU/mL), whatever the fibrosis score. Clinical and biological data were compared between patients who started HCV therapy during follow-up and those who did not.
ResultsIn multivariate analyses, good adherence to treatment for HIV infection, as judged by the patient's physician, was associated with HCV treatment initiation [odds ratio (OR) 2.37; 95% confidence interval (CI) 1.17-4.81; P = 0.017], whereas patients with children (OR 0.53; 95% CI 0.30-0.91; P = 0.022) and those with cardiovascular disease or respiratory distress (OR 0.10; 95% CI 0.01-0.78; P = 0.03) were less likely to be treated.
ConclusionsAdherence to treatment for HIV infection, as judged by the patient's physician, appears to have a major influence on the decision to begin treatment for HCV infection in coinfected patients. This calls for specific therapeutic education and adherence support in order to ensure timely anti-HCV therapy in this population.
IntroductionCompared with isolated hepatitis C virus (HCV) infection, concurrent infection by HIV and HCV results in more rapid progression towards cirrhosis and liver failure [1,2]. In the last decade, chronic liver disease, mainly resulting from HCV infection, has become one of the leading causes of morbidity and mortality in HIV-infected patients [3]. In the first published trials of anti-HCV therapy in this setting, the pegylated interferon alpha (peg-interferon) and ribavirin combination was less effective in HIV-coinfected patients. Sustained virological response (SVR) rates ranged from 14 to 38% among patients with HCV genotype 1 infection and The outcome variable was the initiation of HCV treatment, defined as the first prescription of peg-interferon and ribavirin to an HCV-treatment-naïve patient during follow-up (between 2005 and 2011). In a first analysis, clinical and biological data were compared between patients with an indication for HCV therapy and who started treatment during follow-up (patients with Ն F2 fibrosis, patients infected with genotype 2 or 3, and patients infected with genotype 1 or 4 who had a low viral load (< 800 000 IU/mL), whatever the fibrosis score), and patients who remained HCV-treatment-naïve. The second analysis was restricted to patients with a formal indication for HCV therapy, i.e. a fibrosis score Ն F2 regardless of the HCV genotype.Liver fibrosis was assessed by liver histology or noninvasive methods ...
