          Key Clinical Message

          An Austrian patient with diabetes mellitus type 2 developed visceral leishmaniasis after trips to Spain and Crete, presenting with slight bicytopenia, later developing severe pancytopenia. Travel history taking is important due to an extended incubation period. Coexistence of diabetes mellitus can impair T lymphocyte function and cause higher relapse rates.

            Consequences of alcohol consumption on host defence.

            B Szabo (2015)
            This communication reviews recent literature and summarizes current views on the immunomodulatory effects of acute and chronic alcohol consumption. Chronic and even acute, moderate alcohol use can increase host susceptibility to infections caused by bacterial and viral pathogens. Impaired host defence after alcohol exposure appears to be linked to a combination of decreased inflammatory response, altered cytokine production, and abnormal reactive oxygen intermediate generation. Furthermore, cellular immunity, particularly antigen-specific immune response, is impaired by both acute and chronic alcohol use. Although T lymphocyte functions can be directly affected by ethanol, decreased antigen presenting cell function appears to be a key element in the ethanol-induced decrease in cell-mediated immunity. In addition, a preferential induction of Th2 vs Th1 immune response has been suggested, based on the increased immunoglobulin levels seen in chronic alcoholics. The effects of chronic and acute alcohol consumption in humans, animal models and in vitro systems on host defence and immunity are discussed in the context of the functional abnormalities of T and B lymphocytes, natural killer cells and monocytes/macrophages resulting in the altered immune response seen after alcohol use.

              Polyclonal B cell activation, circulating immune complexes and autoimmunity in human american visceral leishmaniasis.

              In a prospective study, serum and plasma samples from 17 patients with kala-azar were collected in Rio de Janeiro. High levels of immune complexes (IC) were detected in serum by means of 125I-Clq and conglutinin binding assays. The Clq binding material had a sedimentation coefficient of 19-25S, as determined by ultracentrifugation on sucrose gradient. Plasma levels of C3 and C3 breakdown products were measured and the C3d levels were increased in six out of 11 patients. The occurrence of polyclonal B cell activation was suggested by (a) a marked increase of serum IgG and IgM levels and (b) of the presence of antibodies against various proteins and haptens (SRBC, DNP-BSA, FITC-BSA,KLH). There was a close association between the presence of IC and anti-immunoglobulin antibodies. Anti-smooth muscle antibodies were also observed. These data are consistent with a major role of polyclonal B cell activation in the induction of IC during visceral leishmaniasis.
