AB Chronic ethanol (EtOH) abuse in humans leads to a variety of
immunomodulatory events that can alter resistance to a number of
infectious agents. Whether alcohol abuse affects the susceptibility to
human immunodeficiency virus infection or the subsequent development of
acquired immune deficiency syndrome (AIDS) is a matter of extreme
importance; however, available information in humans or animal models is
limited. The goal of this study was to evaluate the effect of chronic
EtOH feeding in mice on the development of immunodeficiency in the
murine model of AIDS (MAIDS). C57BI/6 mice were placed on the
Lieber-DeCarli liquid EtOH diet (25% or 31% total caloric intake) or a
nutrient-matched isocaloric liquid control diet. Seven days later, mice
were infected with the LP-BM5 murine leukemia virus mixture, and groups
of infected and noninfected mice were assayed at defined time points
postinfection for antigen-specific and nonspecific immune responses. In
the absence of retroviral infection, chronic EtOH feeding (5-8 weeks)
led to reductions in spleen weights, compared with isocaloric controls.
In spite of reduced spleen size, mitogenic responses of spleen cells to
concanavalin A (ConA) and lipopolysaccharide (LPS) were elevated in
EtOH-fed mice, as compared with mice fed the control diet. Chronic EtOH
feeding also enhanced the allogeneic mixed lymphocyte response and
increased antigen-specific priming of both B-cells and CD4+ T-cells to
the antigen, sheep red blood cells. In MAIDS-infected mice, chronic EtOH
feeding delayed but did not prevent the onset of virus-induced
immunodeficiency and MAIDS-induced autoantibody synthesis.(ABSTRACT
