BackgroundHypertension (HT) is a disease associated with endothelial dysfunction which is related to some adipokines and pro- and anti-inflammatory cytokines.AimsOur aim was to investigate roles of apelin, omentin-1, and vaspin in essential HT and to evaluate their relationships with other pro- and anti-inflammatory cytokines, trace elements, and oxidative stress. We also investigated these parameters to determine asymptomatic target organ damage period and grading essential hypertension.MethodsOne hundred fifty-three patients diagnosed with essential hypertension and 45 healthy controls were included in the study. Hypertension was defined as a systolic blood pressure > 140 mmHg and/or a diastolic blood pressure > 90 mm Hg or current use of an antihypertensive medication. The patients who had secondary HT, other chronic metabolic, cardiovascular, cerebrovascular diseases were excluded. History and physical exam including detailed cardiovascular examination were performed in all participants. Adipokines, cytokines, trace elements, lipid peroxidation, and ischemia-modified albumin levels were measured in blood samples by biochemical methods.ResultsVaspin, IL-4, IL-8, IL-10, selenium, and zinc levels were significantly lower in the HT group compared to healthy controls while omentin-1, TNF-α, copper, iron, MDA, SOD, and IMA-C levels were significantly higher in HT patients compared to controls. Multiple ordinal regression revealed that TNF-α, IL-10, and body mass index of patients were statistically significant independent predictors (P = 0.024, P = 0.019, and P = 0.032, respectively) for grading of HT. IL-4 and IL-10 were significantly higher in patients with asymptomatic target organ damage, compared to patients without asymptomatic target organ damage (P = 0.032 and P = 0.015, respectively). Our findings suggest that adipokines apelin, omentin, and vaspin may be involved in hypertension by a complex interaction with the anti- and pro-inflammatory cytokines, trace elements, and oxidative stress pathways.
