Alcohol Impairs the Body's Ability to Fight Off Viral Infection, Study Finds

Oct. 2, 2011 — Alcohol can worsen the effects of disease, resulting in longer recovery period after trauma, injury or burns. It is also known to impair the anti-viral immune response, especially in the liver, including response against Hepatitis C (HCV) and HIV. New research published in BioMed Central's open access journal BMC Immunology shows that alcohol modulates the anti-viral and inflammatory functions of monocytes and that prolonged alcohol consumption has a double negative effect of reducing the anti-viral effect of Type 1 interferon (IFN) whilst increasing inflammation via the pro-inflammatory cytokine TNFα.
