Changes of Cytokine Level in Patients with Hypertension and Obesity, Depending on the Duration of the Disease

Interleukins (IL) 2, 6, 10, and C-reactive protein are crucial in arterial hypertension with obesity. Background. To identify the characteristics of inflammatory markers in patients with arterial hypertension and obesity, in accordance with the disease duration. Materials and Methods. The study involved 52 patients with stage II hypertension and obesity, divided in three groups according to the disease duration. In the first group consisted of 19 patients disease duration was 5 years, in the second (18 patients) — 6–10 years, and in the third one (15 patients) — more than 11 years. The serum levels of inflammatory markers were determined by ELISA. Results. When disease duration is 6–10 years, the IL‑6 level is increased slightly compared to the first group, and then decreased. The content of IL‑2 was increased in the first group by 3.74 times, and further decreased by 3.15 times and 3.04 times, respectively, compared to the controls. Levels of IL‑10 and C-reactive protein have the same tendency, as IL‑6. Conclusions. It was found that levels of interleukin 2, 6, 10, and C-reactive protein are significantly increased in patients with hypertension and obesity (greater levels of pro-inflammatory cytokines than the anti-inflammatory). Lengthening the duration of illness leads to less expressive inflammation that may indicate deeper immunological disorders. Initially increased blood concentration of cytokines and C-reactive protein became significantly reduced under standard therapy, but not significantly different from the controls, except the level of IL‑2
