[Exogenous and endogenous risk factors in the development of nonspecific lung diseases in young people]

An organized community numbering 900 normal subjects aged 18 to 19 years were examined. Acute pneumonia was encountered in 15% of persons of the group under study per year. To identify persons with premorbid condition of nonspecific pulmonary diseases, anamnestic screening and outpatient examinations (microbiological and immunologic studies) were performed. As a result, the group constituted by subjects at risk for disease accounted for 18.6%, whereas S. pneumoniae was found in 44.9%. The immunologic findings were compared to the data obtained in the anamnestic screening. It was inferred that certain anamnestic signs correlated with the immune status. The leading factor in the formation of the premorbid condition lies in integral shifts in the immunologic system during adaptation. It follows from the data obtained that persons with risk factors need immune correction.
