title: [The role of cell-mediated immunity in progression of myeloma disease].
abstract: The aim of the work was to study the role of cellular and humoral immunity in progression of myeloma disease (MD). The study included 97 patients and 125 age and sex-matched healthy volunteers. The state of cell-mediated and humoral immunity was evaluated at admission, before the pathogenetic treatment, by indirect immunofluorescence technique using anti-CD3, CD4+, CD8+, CD16+, CD19+, HLA-DR+ monoclonal antibodies. Serum IgA, IgM, IgE, IgG were measured by immunoenzymatic assay. The results were analysed using Statistica 7.0 (StatSoft, USA) program. The quantitative values are expressed as the median (Me) and interquartile range (C25-C75). Qualitative variables are presented as absolute values and percentage. The critical statistical significance level was taken as 0.05. The patients with MD developed combined secondary T, B-cell immunodeficiency. The disbalance between CD4+ cells and cytotoxic lymphocytes as well as signs of B-lymphocyte deficit increased with the progress of the disease. The number of NK-cells decreased at all stages of the disease. A rise in the serum level of LgC at all stages compared with control is an identifying sign confirming diagnosis of G-variant of myeloma disease.
