[Relation between genetic and non-genetic factors of individual susceptibility to silicosis].
The study was carried out at a number of industrial enterprises at risk of silicosis by means of the methodological approach based on the mathematical theory of image discrimination. It was shown that under the given conditions of dust exposure higher or lower probability of the development of silicosis and silicotuberculosis in an individual depended on the whole set of environment and endogenic factors, involving genetic predisposition to the disease as one of the leading factors. The impact of the above factors being similar irrespective of the type of the enterprise, their comparative contribution could be different. Thus reliable prediction of high probability of the disease development could be provided by means of the method of multifactorial analysis only as applied to specific conditions of the given enterprise. In spite of low prevalence of the genotype of silicosis- and silicotuberculosis-associated resistance, under the exposure to quartz dust, high probability of the disease development was predicted only in a number of cases if other individual symptoms were taken into account along the genotype. Therefore it became possible to identify the most susceptible persons at the stage of medical vocational selection.
