CO-MORBID CONDITIONS IN THE VIBRATION DISEASE PATIENTS

. Occupation vibration is the main etiological factor of the vibration disease. Vibration disease disrupts the activity of different systems of the body (nervous, vascular, musculoskeletal, endocrine systems, etc.) which predisposes to the development of co-morbid conditions. Aim of the study. Based on the studying the prevalence and the structure of co-morbid pathology in vibration disease patients to identify the dependence of a polymorbidity on the duration of work experience and severity of vibration pathology, determine a prognosis of “10-year survival” according to the Charlson co-morbidity index. Material and methods. A retrospective analysis of 175 clinical charts of 83 patients of the clinic of the Research Institute for Complex Problems of Hygiene and Occupational Diseases for the period from 2013 to 2018 was carried out. All patients (40-60 years old men) were exposed to vibration in the course of the occupational activity for more than 10 years. Results. Co-morbid conditions in vibration disease were found in 90% of the patients. There most frequent were hypercholesterolemia (52%), dorsopathy (29%), arterial hypertension (27%), sensorineural hearing loss (24%), etc. The results confirm the previously described data on the predominance of co-morbid cardiovascular and metabolic disorders in vibration disease, which are interrelated by pathogenetic mechanisms. The Charlson co-morbidity index in the study group was 2.6 ± 1.04. Average statistical association of the polymorbidity prevalence (φ = 0.21) with the severity of the vibration disease was revealed. Conclusions. The vast majority of the vibration disease patients have co-morbid pathology. More severe damage in vibration pathology is associated with polymorbidity. This relationship is probably due to the mutual worsening of the course of associated diseases.
