- 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
