A group of 138 B cell chronic lymphocytic leukaemia (B-CLL) patients, 83 with active disease and 53 having the indolent form of the disease, were evaluated. The aim of the study was to clarify whether indolent and active B-CLL differ in their immune and hormonal characteristics. Peripheral blood lymphocyte proliferation in response to phytohaemagglutinin, concanavalin A, recombinant interleukin-2, dextran sulphate, Pisum sativatum agglutinin and wheat germ agglutinin was investigated. Serum immunoglobulin and beta 2 microglobulin levels were determined. Adrenocorticotropic hormone (ACTH), cortisol, follicle-stimulating hormone luteinizing hormone, 17 beta-oestradiol, testosterone, triiodothyronine, thyroxine, thyroglobulin and thyrotropic hormone levels were determined by radioimmunoassay. Active and indolent CLL presented differences in immunological characteristics, as demonstrated by the more severe suppression of T lymphocyte function, reduced IgA level and considerably higher serum beta 2-microglobulin values in active disease. Immune disturbances were accompanied by hormonal imbalance, depending on disease status: lower ACTH, cortisol and triiodothyronine levels were established to occur in active CLL compared to indolent disease. Male patients demonstrated striking changes in sex hormones, which were more evident in active disease. The findings point to the complexity of immuno-hormonal disturbances in CLL with differences in the active and indolent state of the disease.

Clinical data and immunoglobulin variable heavy chain (IgVH) gene configuration were analyzed in 47 CLL patients, exposed to ionizing radiation (IR) due to Chernobyl NPP accident, and 141 non-exposed patients. Clean-up workers of the second quarter of 1986 (n=19) were picked out as separate group with the highest number of unmutated cases (94.4%), increased usage of IgVH1-69 (33.3%) and IgVH3-21 (16.7%) genes, high frequency of secondary solid tumors (6 cases) and Richter transformation (4 cases). These preliminary data suggest that CLL in the most suffered contingent due to Chernobyl NPP accident might have some specific features.
