Norepinephrine Spillover

There is increasing evidence that renal denervation is effective in alleviating hypertension associated with elevation of renal sympathetic nerve activity (RSNA) in chronic kidney disease (CKD), but whether this is due to reduction in renal afferent signaling is unclear. We determined the cardiovascular and sympathetic effects of total renal denervation or afferent renal denervation (topical capsaicin) on CKD induced by glomerular layer lesioning of the left kidney and right nephrectomy in conscious rabbits. CKD increased blood pressure by 18±2 mmHg and plasma creatinine by 40% over 2 to 4 weeks (both P <0.001), while RSNA (43%) and total norepinephrine spillover (28%) were elevated in CKD compared with sham (both P =0.04). After total or afferent renal denervation blood pressure, RSNA and norepinephrine spillover were similar or lower than non-CKD (sham) rabbits. While plasma creatinine in CKD rabbits was not affected by total renal denervation, deafferented rabbits had lower levels ( P =0.017). The greater hypotensive response to pentolinium in CKD was also normalized after total or afferent denervation. Heart rate and RSNA baroreflex gain were similar in all groups. The RSNA response to airjet stress was greater in CKD compared with sham but not after total or afferent renal denervation. By contrast, the sympathetic response to hypoxia was similar in sham and CKD intact or deafferented groups but elevated in total denervated CKD animals. We conclude that the elevated sympathetic activity and blood pressure in this model of CKD is predominantly driven by renal afferents.

Abstract. Background/Aims: Trials on the effects of cholecalciferol supplementation in type 2 diabetes with chronic kidney disease patients were underexplored. Therefore, the aim of this study was to investigate the effects of two different doses of vitamin D supplementation on serum 25-hydroxyvitamin D [25(OH)D] concentrations and metabolic parameters in vitamin D-deficient Korean diabetes patients with chronic kidney disease. Methods: 92 patients completed this study: the placebo group (A, n = 33), the oral cholecalciferol 1,000 IU/day group (B, n = 34), or the single 200,000 IU injection group (C, n = 25, equivalent to 2,000 IU/day). 52% of the patients had less than 60 mL/min/1.73m2 of glomerular filtration rates. Laboratory test and pulse wave velocity were performed before and after supplementation. Results: After 12 weeks, serum 25(OH)D concentrations of the patients who received vitamin D supplementation were significantly increased (A, -2.4 ± 1.2 ng/mL vs. B, 10.7 ± 1.2 ng/mL vs. C, 14.6 ± 1.7 ng/mL; p < 0.001). In addition, the lipid profiles in the vitamin D injection group (C) showed a significant decrease in triglyceride and a rise in HDL cholesterol. However, the other parameters showed no differences. Conclusions: Our data indicated that two different doses and routes of vitamin D administration significantly and safely increased serum 25(OH)D concentrations in vitamin D-deficient diabetes patients with comorbid chronic kidney disease. In the group that received the higher vitamin D dose, the lipid profiles showed significant improvement, but there were no beneficial effects on other metabolic parameters.
