Salusins are recently identified endogenous bioactive peptides that have hypotensive and bradycardiac effects. Salusin-beta is involved in the pathogenesis of human atherosclerosis. This was a prospective cohort study of a young patient population with hypertension (HTN). Based on ambulatory blood pressure monitoring (ABPM), the adolescents were categorized into two groups, namely, a hypertensive group consisting of patients with essential (primary) HTN (HTN group) and a group consisting of patients with white-coat HTN [reference (R) group]. Correlations between serum salusin-beta level and clinical, laboratory and ambulatory blood pressure (BP) variables were assessed. The median salusin-beta concentration was significantly higher in patients with essential HTN than in those with white-coat HTN (R group). Salusin-beta was positively correlated with the body mass index Z-score, systolic and diastolic blood pressure (BP) from three independent measurements, mean systolic BP during the daytime, triglyceride (TG) level, and atherogenic index (TG/high-density lipoprotein-cholesterol ratio). The results of this preliminary study suggest that salusin-beta may play an important role in the pathogenesis of HTN in a young population. Further research should focus on the role of salusin-beta in the mechanism of essential HTN and the assessment of possible correlations between salusin-beta and other well-known markers of atherosclerosis in both teenagers and adults. This research should serve as a base for future studies in this field.
