    Abstract:
    Immunologic parameters were evaluated in 22 patients with alcoholic liver disease (ALD). Patients with ALD had increased levels of circulating immune complexes (CIC) and serum immunoglobulins, particularly IgA. The classical complement pathway was preferentially activated in CIC-positive patients. There was no increase in total lymphocyte or total T lymphocyte counts, but a significant rise in both the helper/inducer population (OKT4) and helper/suppressor cell ratio (T4/T8) was noted. The presence of interleukin-2 receptors and HLA-DC/DS and HLA-DR antigens suggested in vivo activation of ALD patients' T cells. The rate of differentiation of B cells to plasma cells was high in both pokeweed mitogen-stimulated and unstimulated cultures of ALD patients' B cells, whereas plasma cell generation doubled when patient T lymphocytes were added to enriched normal B cells. The above data support a role for activated helper (T4+) T cells in the immune response initiated by alcoholic hepatitis. Serum angiotensin-converting enzyme levels and lysozyme levels were increased in ALD patients, and cultured adherent mononuclear cells from ALD patients secreted more lysozyme in vitro than normal cells, suggesting the presence of an activated monocyte-macrophage system in ALD.
