The profile of comorbid conditions and the structure of mortality in patients with rheumatoid arthritis in the Stavropol Territory: preliminary results

Objective: to study the comorbid background and mortality structure of patients with rheumatoid arthritis (RA) in the Stavropol region in a cohort of patients of the Stavropol Regional Clinical Hospital (SRCH) within the period 2015–2021. Materials and methods: There was carried out systematic review of the literature. There was carried out the analysis of the protocols of autopsies in the pathoanatomical department of the SRCH within 2015-2021. There were studied the comorbidity component and lethal outcomes of patients with RA in the pathoanatomical diagnosis. Results: the structure of the comorbid pathology of RA patients in the SRCH cohort included coronary heart disease (CHD), autoimmune thyroiditis (AT), respiratory diseases (RD), hypertension (HT), “Blastomatosis”, diabetes mellitus (DM), COVID-19 infection. The comorbidity profile of patients with RA in decreasing order of the incidence of the pathological condition was as follows: CHD (35.29%) > RD (29.41%) > (“Blastomatosis”, СOVID-19 by 11.75%) > (AT, HT, DM by 5.88%). The structure of the conditions that led to the death of patients with RA included: acute myocardial infarction (40.0%), hemorrhagic stroke (6.67%), breast cancer (13.33%), thyroid cancer (6.67%), viral pneumonia (20.0%), sepsis (13.33%). Conclusions: the data obtained provide information that can be used by rheumatologists to optimize the strategy for managing RA and the risk of comorbid conditions.
