People with HIV/hepatitis C virus (HCV) co-infection are between a quarter and a third more likely to develop cardiovascular disease compared to people of a similar age with HIV mono-infection, according to the results of a meta-analysis published in the Journal of Viral Hepatitis. Co-infection increased the risk of stroke by 24% and the risk of heart attack by 33%.
“In this meta-analysis of 33,723 participants from four cohort studies, HIV/HCV coinfection was associated with a 24%-33% increased risk of CVD [cardiovascular disease] compared to HIV monoinfection,” write the investigators. ‘In coinfected individuals, it has been postulated that both viruses may act synergistically through persistent inflammatory responses to increase the risk of CVD.”
There is a well-established link between HIV infection and CVD, with research suggesting that the risk is increased by as much as 61% compared to HIV-negative individuals. People with HCV also have an increased risk of developing CVD. It has therefore been suggested that HIV and HCV have the potential to act synergistically and increase the risk of CVD in individuals with co-infection. Studies examining whether this is the case have yielded conflicting results. To clarify this question, investigators in the United States performed a meta-analysis of studies examining the risk of CVD in adults with HIV/HCV co-infection compared to people with HIV mono-infection. Risk of CVD – coronary heart disease, congestive heart failure and stroke – was adjusted for traditional risk factors including sex, smoking, blood pressure, diabetes and LDL cholesterol.
Four cohort studies (two prospective, two retrospective) met the inclusion criteria. A total of 33,723 were included in the analysis. The majority were men and mean age varied between 36 and 48 years. Average follow-up was between 2.3 and 7.3 years. The studies were conducted in the United States, Canada and Spain.
