Quality of life and cost-effectiveness of anti-HCV therapy in HIV-infected patients

Abstract

Quality of life studies in chronic hepatitis C using specific questionnaires have been performed in mono-infected patients; however, these studies have just begun in HIV-HCV co-infected patients. The questionnaires used in mono-infected patients are not well adapted for co-infected patients and need to be redesigned. Typically, co-infected patients have multiple symptoms that may be attributable to HIV, to HCV, to a combination of both diseases or even to side effects related to drug therapy. These patients usually need substitutive therapy to manage side effects related to HCV therapy, particularly anaemia, leukopenia and depression. There are no cost-effectiveness studies published on the current HCV standard therapy with pegylated interferon and ribavirin. However, there is some research on the old standard interferon and ribavirin, which shows that HCV therapy is cost-effective. Cost-effectiveness studies in co-infected patients will have to take into account variables that do not affect mono-infected patients, such as the different levels of CD4, the increase in the fibrosis progression rate and the use of other expensive drugs for the management of side effects. Currently, the literature does not provide adequate information on the effect of HCV infection on the quality of life of HIV-HCV co-infected patients or the most cost-effective HCV therapy.
