AimThe aim of the study was to study the frequency of occurrence of exposure to harmful occupational factors in patients with sarcoidosis of the respiratory organs, depending on the course of the disease.Materials And MethodsAn open prospective study included 121 patients with sarcoidosis of the respiratory system from the age of 21 to 66 years, from 20072019. The diagnosis was histologically confirmed in all patients. Patients underwent a set of laboratory and instrumental examinations, studied profane history. The presence of a history of contact with harmful and dangerous production factors was clarified. To determine the effect of a harmful production factor on the course of sarcoidosis, patients were divided into 2 clinical groups: the first group consisted of 85 (70.2%) patients with a favorable course of the disease, the second group included 36 (29.8%) patients with an unfavorable course sarcoidosis (standardization coefficient between groups 2.4:1).Results And DiscussionAmong the examined patients of working age prevailed (87%). Patient groups were comparable by age, but statistically differed by gender (chi2=9.75, p=0.0018). Frequency analysis of the occurrence of harmful occupational factors in sarcoidosis of the respiratory organs showed that the most frequently encountered factors in all the studied groups were contact with chemical hazards.ConclusionThe presence of contact with harmful production factors increases the risk of an unfavorable course of sarcoidosis by more than 2 times.
