In children with PH, peripheral blood leukocytes express adiponectin receptors, and the expression is inversely correlated with the serum adiponectin levels irrespective of BMI; however, it correlates with the severity of hypertension—the more severe the hypertension, the greater the expression of adiponectin receptors and lower adiponectin concentrations [66]. This evidence concerns the gene ADIPOQ and hypertensive disorder.
