Vitamin D deficiency has been implicated in chronic pain. Immigrant and ethnic minority populations have been shown to have lower vitamin D levels than native Western populations and often to be vitamin D deficient. This systematic review investigates the relationship between vitamin D and chronic pain in immigrant and ethnic minority populations. Included were studies reporting on 25-OH vitamin D levels in immigrant/ethnic minority populations affected by chronic pain, and/or reporting on the treatment of chronic pain with vitamin D preparations in such populations. We found that 25-OH vitamin D levels were low and often deficient in immigrant/ethnic minority populations. Vitamin D levels depended on the latitude of the study location and hence sunlight exposure. There was insufficient evidence to reach a verdict on the value of treating chronic pain in immigrant/ethnic minority patients with vitamin D preparations because the studies were few, small, and of low quality.

Abstract Background The roles of FTO gene and the level of serum 25-OH-vitamin D in obesity are frequently reported. This study aimed to investigate the interactions of serum 25-OH-vitamin D level, FTO and IRX3 genes expression, and FTO genotype in obese and overweight boys. Methods This study was carried out on the 120 male adolescents with overweight in Tehran, Iran. Blood samples were collected from the participants in order to evaluate the serum level of 25-OH-vitamin D, the expression level of FTO and IRX3 genes, and FTO genotype for rs9930506 at baseline and after 18 weeks of the study. Results In general, no significant association was found between serum 25-OH-vitamin D level and IRX3 and FTO genes expression. The results of linear regression on the relationship between 25-OH-vitamin D serum level and FTO and IRX3 genes expression based on FTO genotypes for rs9930506 indicated that in AA/AG genotype carriers, serum 25-OH-vitamin D level was positively associated with FTO gene expression (B = 0.07, p = 0.02) and inversely associated with IRX3 gene expression (B = − 0.07, p = 0.03). In GG carriers, serum 25-OH-vitamin D level was not associated with expression of IRX3 and FTO genes. Conclusion There are significant interactions between 25-OH-vitamin D and the expression of FTO and IRX3 genes in the subset of obese patients with specific genotypes for FTO rs9930506. There was no association between serum 25-OH-vitamin D levels and the expression of FTO and IRX genes in individuals with a homozygous genotype for the risk allele of the FTO gene polymorphism.

Abstract Objective: To compare the efficacy of daily versus low dose depot oral vitamin D3 for treating nutritional rickets. Design: Randomized Controlled Trial Setting: Paediatrics department of a tertiary care hospital catering to semi-urban and rural population in Delhi, India Methods: We randomized 66 children aged 3 months to 5 years with nutritional rickets to receive either daily oral vitamin D3 drops (3-12 months: 2000 IU; >12 months-5y: 4000 IU; n=33) for 12 weeks duration, or a single oral depot dose of vitamin D3 granules (3-12 months: 60,000 IU; >12 months-5y: 150,000 IU; n=33). Results: Participants in both groups had comparable demographic characteristics, laboratory features and radiological severity of rickets. 33 participants in each group received the assigned intervention and all were followed up till 12 weeks. At 12 weeks follow up, children in both groups showed a significant improvement in all biochemical parameters [serum calcium, phosphorus, alkaline phosphatase, parathormone and 25(OH) vitamin D levels] as well as radiological healing. At 12 weeks, the mean (SD) serum 25(OH) vitamin D levels (nmol/L) were statistically comparable in both groups [daily: 120.2 (83.2), depot: 108 (74), P=0.43] and 31 (94%) children in each group had radiological healing (Thacher score <1.5). Two children in each group persisted to have raised alkaline phosphatase and one child each in the daily group continued to have hypocalcemia and hypophosphatemia at 12 weeks. Conclusion: Low dose oral depot vitamin D3 is an effective alternative to daily oral vitamin D3 for nutritional rickets.

ABSTRACT Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

Adjustment Equation

AimsMany clinical laboratories in the UK use a standard equation to adjust total calcium for albumin concentration. To assess the validity of this practice, we assessed the effect of the use of a traditional and locally derived calcium adjustment equation on parathyroid hormone (PTH) and 25(OH, hydroxy) vitamin D levels.MethodsSamples requested for calcium and albumin measurement over a 6 month period that met inclusion criteria were used to derive a calcium adjustment equation (n=60 941). The traditional and locally derived calcium adjustment equations were then applied to a second cohort of adult patients that underwent calcium measurement over a 1 year period (n=275 456). Patients were classified as hypocalcaemic, normocalcaemic or hypercalcaemic using a UK Pathology Harmony adjusted calcium reference interval (2.2–2.6 mmol/L).ResultsThe local calcium adjustment equation provided a 7.1-fold reduction in the prevalence of hypocalcaemia. Patients classified as hypocalcaemic using the locally derived equation had statistically significantly lower 25(OH) vitamin D and higher PTH levels. A 2.4-fold increase in the prevalence of hypercalcaemia was also observed using the new equation, but with no significant difference in 25(OH) vitamin D or PTH levels.ConclusionsA locally derived calcium adjustment equation reclassified the calcium status of 61 278 (22%) patients. Patients classified as hypocalcaemic by the locally derived equation had significantly lower 25(OH) vitamin D and significantly higher PTH values, providing evidence that use of this adjustment equation generates adjusted calcium results of greater clinical relevance. This study provides further and novel evidence that individual laboratories should determine local equations for adjusted calcium where possible.
