[Comparative analysis of various indicators of venous blood and peripheral lymph in healthy subjects]

Over four hundred industrial workers underwent immunological examination for quantitative and functional evaluation of the main blood lymphocyte and neutrophil subpopulations and reactions of sensitization to industrial allergens at the cellular and subcellular levels. Concurrent quantitative and functional T- and B-lymphocyte deficiency was revealed in 17.5 per cent workers; the majority of subjects were found to have changes in specific indices (30 per cent) or heterogeneous changes (11.5 per cent). The incidence and magnitude of the secondary immunodeficiency signs are shown to be dependent on the main unfavourable factors of the industrial environment which are also related to the sensitization to the industrial allergens, developing primarily in T- and B-lymphocyte deficient subjects (40 per cent of the 69 per cent sensitized). A principle of group formation is proposed for the dynamic follow-up of the outcome of the revealed signs of secondary immunodeficiency and their effect on the workers' health. A methodology is established for revealing secondary immunodeficiency state and sensitization during mass immunological examinations of industrial workers.
