ABSTRACT Aim: Current guidelines do not address between-person variability in markers of bone and mineral metabolism across subgroups of patients, nor delineate treatment strategies based upon such factors. Methods: A cross sectional study was carried out to analyze data from 20,494 United States Veterans and verify the variability of Vitamin D (25(OH)D) and parathyroid hormone (PTH) levels across race and stage of chronic kidney disease. Results: PTH levels were higher in Black Americans (BA) than White Americans (WA) at all levels of 25(OH)D and across eGFR strata. There was a progressive decline in PTH levels from the lowest (25(OH)D < 20) to highest quartile (25(OH)D >=40) in both BA (134.4 v 90 pg/mL, respectively) and WA (112.5 v 71.62 pg/mL) (p<0.001 for all comparisons). Conclusion: In this analysis, higher than normal 25(OH)D levels were well tolerated and associated with lower parathyroid hormone values in both blacks and whites. Black Americans had higher PTH values at every level of eGFR and 25(OH)D levels suggesting a single PTH target is not appropriate.

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.

Combined Supplementation

Vitamin K (VK) and vitamin D (VD) deficiency/insufficiency is a common feature of chronic kidney disease (CKD), leading to impaired bone quality and a higher risk of fractures. CKD patients, with disturbances in VK and VD metabolism, do not have sufficient levels of these vitamins for maintaining normal bone formation and mineralization. So far, there has been no consensus on what serum VK and VD levels can be considered sufficient in this particular population. Moreover, there are no clear guidelines how supplementation of these vitamins should be carried out in the course of CKD. Based on the existing results of preclinical studies and clinical evidence, this review intends to discuss the effect of VK and VD on bone remodeling in CKD. Although the mechanisms of action and the effects of these vitamins on bone are distinct, we try to find evidence for synergy between them in relation to bone metabolism, to answer the question of whether combined supplementation of VK and VD will be more beneficial for bone health in the CKD population than administering each of these vitamins separately.

Objective: To determine whether patients with chronic kidney disease (CKD) without dialysis their stage impacts the native vitamin D levels. Methods: Patients over 18 years with chronic kidney disease stage 2-5 without dialysis treatment. They demographic, anthropometric variables, degree of sun exposure, disease etiology and laboratory variables related to bone and mineral disorders were evaluated. Study analytical cross-sectional prospective. Descriptive statistical methods for quantitative and qualitative are characterized, and analytical correlation between levels of vitamin D statistical laboratory tests related to bone and mineral disorders, sun exposure and ethnicity variables for each stage were characterized. By descriptive statistical methods, quantitative and qualitative variables were characterized, and analytical statistical correlation between levels of vitamin D with laboratory tests related to bone and mineral disorders, sun exposure and ethnicity for each stage were practiced. Results: 331 patients were evaluated, with a mean age of 71 years, the mestizo majority (71%), 173 women, main etiology of CKD hypertensive nephropathy (33.2%). 21.1% of patients had normal levels of vitamin D, 70.1% insufficient, and 8.8% in deficit. Negative correlation was detected between the levels of vitamin 25(OH)D and serum creatinine, phosphorus, calcium x phosphorus product, PTH, proteins in urine 24 hours and BMI. Positive correlation for calcium and albumin. Positive statistical significance between the levels of vitamin 25(OH)D and sun exposure for 3b and 4 stages was found. Conclusions: In patients with CKD is common to detect low levels of vitamin 25(OH)D, which can contribute to the generation of secondary hyperparathyroidism.
