- Not as much active vitamin D if poor kidney function and low vitamin D – March 2015
- UVB increases vitamin D even if poor kidney by changing CYP27B1 genes in skin – Dec 2013
- Kidney Inflammation: both prevented and reduced by Vitamin D – review Jan 2014
Overview Kidney and vitamin D contains the following summary
- FACT: Kidney is the primary way to activate vitamin D
- FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
- FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
- FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
- FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
- FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
- Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
Calcitriol - which bypasses the need for the kidney to activate vitamin D
Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications
Update: Pre-cursor of active vitamin D made from plants is better than calcitriol – Sept 2012
- Category Kidney and Vitamin D contains
Kidney Intervention trials using Vitamin D:
- Diabetic nephropathy (Kidney) treated by 50,000 IU of vitamin D weekly – RCT Jan 2019
- Hemodialysis patients (CKD) helped by weekly 50,000 IU of vitamin D – Jan 2017
- Kidney disease helped by active or high dose Vitamin D - Feb 2014
- Peritoneal Dialysis nicely treated by active vitamin D – July 2013
- 7100 IU (50000 weekly) restored vitamin D levels for those with Chronic Kidney Disease – July 2012
- Chronic Kidney Disease reduced with 3600 IU vitamin D (50000 twice a month)– RCT Aug 2012
- Overview Kidney and vitamin D
Pages listed in BOTH of the categories Infant/Child and Kidney
- Sudden kidney infection in children was 9X more likely if poor Vitamin D receptor – July 2018
- Every child with kidney problems (ideopathic nephrotic syndrome) had low vitamin D – Oct 2015
- Chronic kidney with low vitamin D: 90 percent of pediatric nephrologists now recommend more D – Feb 2013
- 2000 IU vitamin D3 was not enough for children with chronic kidney disease – Feb 2013
Cross-sectional studies of children with prevalent nephrotic syndrome (NS) have shown 25-vitamin D (25(OH)D) deficiency rates of 20-100 %. Information on 25(OH)D status in incident patients or following remission is limited. This study aimed to assess 25(OH)D status of incident idiopathic NS children at presentation and longitudinally with short-term observation.
Multicenter longitudinal study of children (2-18 years old) from 14 centers across the Midwest Pediatric Nephrology Consortium with incident idiopathic NS. 25(OH)D levels were assessed at diagnosis and 3 months later.
Sixty-one children, median age 5 (3, 11) years, completed baseline visit and 51 completed second visit labs. All 61 (100 %) had 25(OH)D < 20 ng/ml at diagnosis. Twenty-seven (53 %) had 25(OH)D < 20 ng/ml at follow-up. Fourteen (28 %) children were steroid resistant. Univariate analysis showed that children prescribed vitamin D supplements were less likely to have 25(OH)D deficiency at follow-up (OR 0.2, 95 % CI 0.04, 0.6). Steroid response, age, and season did not predict 25(OH)D deficiency. Multivariable linear regression modeling showed higher 25(OH)D levels at follow-up by 13.2 ng/ml (SE 4.6, p < 0.01) in children supplemented with vitamin D.
In this incident idiopathic NS cohort, all children at diagnosis had 25(OH)D deficiency and the majority continued to have a deficiency at 2-4 months. Supplemental vitamin D decreased the odds of 25(OH)D deficiency at follow-up, supporting a role for supplementation in incident NS.
