and inhibits Th17 cells. The immune-modulatory role of vitamin D in chronic kidney disease (CKD) and renal transplant patients is unclear. We measured whether different serum levels of vitamin D were associated with an increased or decreased presence of lymphocyte subsets including Treg and Th17 cells in end-stage renal disease (ESRD) and renal transplant recipients. Methods: Eighty-seven renal transplant recipients and 53 end-stage renal disease (ESRD) patients were enrolled in this study. The absolute counts of CD4+ and CD8+ T, CD16+ CD56+ NK, CD19+ B, CD4+ CD25+ CD127- Foxp3+ (Tregs), Helios+ Tregs, CD38+ Tregs, and CD4+ CD17+ (Th17) cells were analyzed in peripheral blood in both patient groups. In addition, serum 25 (OH) D3, 1, 25 (OH)2 D3, IL-6, IL-17, IL-23, and TGF-β1 were measured. The association between lymphocyte subset counts and 1, 25 (OH)2 D3 or 25 (OH) D3 was studied, as was the association between serum IL-6, IL-17, IL-23, or TGF-β1 and 1,25 (OH)2 D3 or 25 (OH) D3. Results: Serum 25 (OH) D3 and 1,25 (OH)2 D3 levels were not independently associated with peripheral CD4+ T, CD19+B, CD16+CD56+NK, Treg, or Th17 cell counts. In contrast to serum 25 (OH) D3, serum1, 25 (OH)2 D3 was positively associated with CD8+ T cells counts in renal transplant recipients. Conclusion: Our findings indicate low utility of serum 25 (OH) D3 and 1, 25 (OH)2 D3 levels in predicting a change in lymphocyte subset counts in ESRD and renal transplant patients.

Background Ginkgo biloba extract 761 (EGb761) was studied for its nephroprotective effects in experimentally induced hypertension. Hypertension is increasingly a cause of end‑stage renal diseases. Increased cytokine release and oxidative stress are mechanisms that appear to be involved in the pathogenesis of hypertensive renal damage. EGb has antioxidant and anti‑inflammatory effects and can attenuate hypertensive renal damage. Methods and results Male adult Wistar rats were used in this study. Hypertension was induced in these rats by administering l‑NG‑nitroarginine methyl ester (l‑NAME) (10 mg/kg/day, intraperitoneal) for 12 weeks. Another group of rats received l‑NAME and EGb761 (100 mg/kg/day, orally) starting from the ninth week to the end of treatment. It was found that the blood pressure was reduced at the end of 12th week in rats treated with EGb761 compared with l‑NAME‑treated (hypertensive) rats. EGb761‑treated rats showed lower renal tissue malondialdehyde level and renal tissue tumor necrosis factor‑ level when compared with l‑NAME‑treated rats (hypertensive). Conclusion EGb761 has antihypertensive effect; it can protect the kidney from hypertension through the reduction of renal inflammation and oxidative stress.
