Abstract
Aim. To analyze the link between levels of adipocytokines (leptine), non-specific cytokines (interleukin-6, tumor necrosis factor-α) and arterial hypertension. Methods. 123 subjects, including 100 patients with metabolic syndrome (according to 2005 Criteria of International Diabetes Federation) and 23 healthy subjects, were examined. General examination was performed, body weight, height and waist circumference were measured, body mass index was calculated. Following laboratory test were performed: serum leptin, interleukin-6, tumor necrosis factor-α, main classes of immunoglobulin, C-reactive protein levels were measured. Results. In patients with metabolic syndrome, increased body weight was associated with increased risk of arterial hypertension. A 10-fold increase of serum leptin level (44.69±8.96 ng/ml) compared to healthy controls (4.72±1.33 ng/ml, p <0.01), was revealed. Leptin level elevation was strongly associated with increased body mass index (r=0.77; p <0.001). Tumor necrosis factor-α concentration in patients with metabolic syndrome exceeded 2 pg/ml, while in healthy controls it didn’t reach this level. Interleukin-6 level was elevated in patients with metabolic syndrome (7.32 [3.25; 7.17] pg/ml) compared to controls (1.53 [1.19; 2.49] pg/ml, Fisher’s exact test, p <0.001). Examination of immunoglobulin levels in patients with metabolic syndrome revealed decreased serum level of immunoglobulin E (97.12±66.24 IU/ml) compared to controls (60.47±19.04 IU/ml, p=0.01). Concentration of immunoglobulin G in patients with metabolic syndrome was also higher (14.61±3.50 g/l) compared to controls (12.57±2.07 g/l, p=0.009). Increased interleukin-6 and immunoglobulin G levels were associated with presence of arterial hypertension. Conclusion. Increased interleukin-6 and immunoglobulin G might be an important factor for arterial hypertension onset and progression.
