Background: Chronic recurrent pain is a clinical symptom of rheumatologic diseases with primary joint damage. The mechanisms of chronic pain syndrome development are often associated with depression. Methods: The study enrolled 67 patients with ostheoarthrosis (OA), rheumatoid arthritis (RA) and lower back pain. The average subject age was 59, 5 ± 5, 3; 24 were males and 43 were females. In order to achieve the study objective, Luscher test, CES-D; TAS; Spielberg-Hanin's scale; MMPI; VAS scale and McGill Pain Questionnaire were used. Results: Following the testing results, 32 (47,8%) of 67 patients were diagnosed with chronic pain syndrome associated with depression respectively р=0,002. The average pain syndrome (PS) level by VAS scale in patients with depression was almost 1,7 times higher than in patients without psychological disorders, 8,6±0,9 vs. 5,2±1,09; р <0,001. Under adaptive tension conditions, when the MMPI profile exceeded 70 Т-scores, PS tended to exacerbate (р<0,001), while manifestation of depression symptoms correlated with PS (г= 0,627) and the presence of personality traits accentuation (г= 0,531), along with increased anxiety (г= 0,425), asthenic condition (г= 0,392) and general TAS alexithymia score (г= 0,473). After the course of therapy involving antidepressant drugs, PS decreased by 2,9 times as compared to the baseline level, р <0,001. Conclusion: Indications for antidepressant use in patients with PS include the chronic pain syndrome associated with depression at the background of basic anti-inflammatory therapy.
