Abstract
ABSTRACTWe deduced that leukocyte-derived H2S would also play a pivotal role regarding nutrition homeostasis in hypertensive subjects. Plasma was obtained from patients with hypertension (n = 151) as well as control (n = 41). Leukocyte-derived H2S speed was determined, and biochemical indices of glucose and lipid metabolism were measured. Western blot analyses of CSE were also performed. Inflammation factors were measured. Leukocyte-derived H2S is produced at a significantly lower rate in overweight or obese patients (p < 0.05). There is a significant negative correlation between H2S and the levels of HOMA-RI and insulin in overweight patients and has a positive relationship with HDL-C only in overweight hypertensive patients (p < 0.05). Patients with high insulin levels showed down-regulation of CSE (p < 0.05). The levels of IL-10 decreased in both the obese and the overweight which showed significant relationship with all metabolism parameters such as HDL-C(r = 0.176, p = 0.031), insulin (r = −0.181, p = 0.027), HOMA-IR (r = −0.166, p = 0.045), and H2S speed (r = 0.995, p = 0.001). Linear regression analysis showed that insulin levels will increase (β = −1.685, p = 0.041) with the slower speed of H2S. Leukocyte-derived H2S production varied according to the nutritional status of hypertensive subjects, and the H2S/IL-10 signaling pathway may be the junction point among hypertension, disturbance of nutritional status, and inflammation.
