- Abstract
The importance of metabolic disorders in the pathophysiology of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections is becoming increasingly apparent. Metabolic anomalies, with their potential for multiple-organ involvement, are to be expected, given the chronic nature of these diseases, and the intracellular dysregulation associated with them. Not only have the endocrine and cytokine metabolic anomalies seen in HIV and HCV infections been linked with the metabolic syndrome, but they also appear to have some pathways in common. Studying the differences and similarities between these metabolic anomalies may add to our understanding of HIV and HCV infection, and provide guidance on how to treat these chronic diseases. This review highlights the principal underlying factors for metabolic disorders in these chronic viral diseases-namely insulin resistance and liver damage. Both the chronic viral state itself and the host immune response give rise to glucose and lipid metabolic disorders that, in turn, are risk factors for hepatic damage. The various interactions between HIV and/or HCV with insulin resistance, type 2 diabetes, steatosis and fibrogenesis should be considered when determining the treatment and long-term follow-up of patients. Recent data indicate that HCV clearance improves insulin resistance and hepatic function in HCV-infected patients treated with interferon with or without ribavirin.
