Osteoarthritis is one of the most common diseases in Ukraine and worldwide, often leading to early disability in people of working age, making it both a medical and social concern. According to the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis, and Musculoskeletal Diseases, as well as the International Society for the Study of Osteoarthritis, it is known that a middle-aged patient with osteoarthritis typically has four accompanying pathologies. In elderly patients, in addition to osteoarthritis, up to eight other chronic conditions are often diagnosed. Comorbidity is frequently observed in middle-aged patients with osteoarthritis. Understanding the pathogenetic links between osteoarthritis and comorbid conditions plays an important role in the timely diagnosis and treatment of these diseases, helping to maintain a high quality of life for patients.
Objevtive: the study of the pathogenesis of osteoarthritis and arterial hypertension, along with the proposed therapy for treating comorbidities in patients with both osteoarthritis and arterial hypertension, aims to enhance the treatment outcomes.
Materials and methods. Analytical and bibliosemantic methods were used in this study. During the scientific search, 38 modern literature sources were reviewed and analyzed concerning the pathogenetic impact on the development of osteoarthritis and arterial hypertension, as well as their shared mechanisms in the development and progression of both conditions.
The study was carried out at the Department of Family Medicine and Therapy of the Regional Rheumatology Center, M. V. Sklifosovsky Poltava Regional Hospital. A total of 50 people were examined; the main group consisted of 35 individuals with stage II hypertension, grade 2, combined with stage II knee osteoarthritis (according to the Kellgren-Lawrence scale), with joint dysfunction of stages 1-2. These patients were aged 40-65 years (mean age 51.8±2.14 years). The duration of hypertension was 10.07±1.24 years, and the duration of manifested osteoarthritis was 8.56±1.03 years. The comparison group consisted of 20 individuals with stage II, grade 2 hypertension (mean age 52.5±2.38 years), with a mean hypertension duration of 11.31±1.17 years. The clinical diagnosis of osteoarthritis was established according to the recommendations of the European Alliance of Associations for Rheumatology (2018). The diagnoses of comorbid conditions were confirmed in accordance with relevant orders from the Ministry of Health of Ukraine, with verification by specialized experts. Patients with osteoarthritis received standard treatment, and, when necessary, additional treatment for comorbid conditions was prescribed (a hypotensive combination of an ACE inhibitor and long-acting calcium.
Results: The presence of osteoarthritis exerts an additional negative impact on heart rate variability in patients with hypertension. The reduction of the Low Frequency/High Frequency (LF/HF) index due to the use of this therapy (a combination of an ACE inhibitor and a long-acting calcium antagonist in doses of 4/5 mg, 4/10 mg, 8/5 mg, 8/10 mg) in the treatment of patients with comorbidity of hypertension and osteoarthritis contributes to the activation of the sympathetic nervous system, reduction of patient mortality, balancing of the nervous system by inhibiting sympathetic nervous tone, and lowering high blood pressure.
Conclusions: The proposed combination therapy for patients with osteoarthritis and hypertension contributes to prolong remission of both the primary disease and comorbid conditions, reduces the frequency of hospitalizations, and shortens inpatient treatment by 3-4 days.
