Abstract

GUTIERREZ-GROBE, Ylse; PONCIANO-RODRIGUEZ, Guadalupe  and  MENDEZ-SANCHEZ, Nahum. Viral hepatitis infection and insulin resistance: a review of the pathophysiological mechanisms. Salud pública Méx [online]. 2011, vol.53, suppl.1, pp. S46-S51. ISSN 0036-3634.  http://dx.doi.org/10.1590/S0036-36342011000700009.

Viral hepatitis is a common cause of morbidity in Mexico. Insulin resistance (IR) is related to the liver damage caused by some viral infections, especially chronic infections. Chronic viral infection is an important risk factor for the development of type 2 diabetes mellitus, disease that is currently among the 10 main causes of morbidity and the most common cause of mortality. Although several studies have reported an association between IR and hepatitis B virus or hepatitis C virus (HCV) infection, the pathophysiology has been studied thoroughly only for the association between IR and HCV infection. It is thought that HCV infection causes direct damage through the action of the core proteins, which induces an inflammatory state characterized by secretion of proinflammatory cytokines that interfere with normal insulin signaling and disturb glucose, lipid and protein metabolism. This review summarizes the mechanisms by which viral infection is thought to induce IR.

Keywords : insulin resistance; hepatitis B virus; hepatitis C virus.
