Abstract:
:Changes in the concentration and composition of serum immunoglobulin A (IgA) and deposits of IgA in tissues are well-known characteristics of alcoholic liver disease. We investigated whether these changes also accompany IgA synthesis by peripheral blood mononuclear cells (MNC), by counting immunoglobulin-producing cells using a solid-phase enzymatic 'spot' test, and by analysis of immunoglobulin content in lysed cells with culture supernatant using conventional enzymatic methods. Patients with alcoholic liver disease exhibited a significantly higher number of spontaneously IgA-producing cells than did normal healthy controls (1.7 X 10(6) cells/blood and 0.5 X 10(6) cells/blood, respectively, P less than 0.01). The IgA content of MNC directly after isolation was also higher (38 and 13 ng/10(6) MNC, respectively, P less than 0.01), as was the IgA production during an unstimulated 6-day culture period (520 and 95 ng/10(6) MNC put into culture, respectively, P less than 0.001). The spontaneously IgA-producing cells assessed directly after isolation of mononuclear cells correlated with the IgA production during an unstimulated culture (P less than 0.01). We conclude that in alcoholic liver disease, B lymphocytes circulate which may have been activated in vivo.
