Abstract
Objective: Dysregulated leptin and adiponectin profile is known to be associated with atherosclerotic disease. The evaluation of the leptin to adiponectin (L/A) ratio has been suggested as a powerful useful atherosclerotic index compared with adiponectin and leptin alone in patients with type 2 diabetes and obesity. In this study, we investigated the usefulness of L/A ratio for vascular structural abnormalities in essential hypertensive patients. Design and method: In 151 untreated essential hypertensive patients (86 males, average age 56 ± 12 years) without chronic kidney disease (urinary albumin excretion (UAE) less than 300 mg/g of creatinine and estimated glomerular filtration rate 60 mL/min/1.73m2 or more), blood sampling, 24-hour urine collection, and 24-hour blood pressure monitoring were performed. Intima-media thickness of carotid artery (IMT) and minimal forearm vascular resistance (MVR) (wall to lumen ratio in resistance vessel) were also measured by using ultrasonography and strain-gauge plethysmography, respectively. Results: L/A ratio was higher in men than in women (1.23 ± 1.56 vs 0.73 ± 0.87, p < 0.05). There was no correlation between L/A ratio and systolic and diastolic blood pressure, and pulse rate. L/A ratio correlated positively with body mass index, triglyceride, hemoglobin A1c, HOMA-R and urinary C-peptide excretion (r = 0.57, 0.20, 0.20, 0.31, 0.27, p < 0.05, respectively) and negatively with HDL-cholesterol (r = -0.24, p < 0.05). In addition, UAE, IMT and MVR were increased accompanying incremental L/A ratio (r = 0.20, 0.17, 0.19, p < 0.05, respectively)In addition, UAE, IMT and MVR were increased accompanying incremental L/A ratio (r = 0.20, 0.17, 0.19, p < 0.05, respectively), whereas these indices did not associated with leptin and adiponectin individually. In multiple regression analysis, L/A ratio was an independent determinant for UAE, IMT and MVR. Conclusions: In patients with essential hypertension, L/A ratio was associated with obesity, abnormal glucose and lipid metabolism, increase in microalbuminuria, and arterial and arteriolar sclerosis. L/A ratio was considered as a useful indicator of vascular structural abnormalities in patients with essential hypertension.
