BACKGROUND: Vitamin D (vitD) deficiency is prevalent among childhood hematopoietic stem cell transplantation (HSCT) recipients and associated with inferior transplant survival at 100 days after transplantation. Achieving and maintaining therapeutic vitD levels in HSCT recipients is extremely challenging in the first 3-6 months after transplant due to poor compliance in the setting of mucositis, and concomitant use of critical transplant drugs that interfere with vitD absorption. We sought to evaluate the safety and efficacy of a single, ultra-high dose of vitD given prior to childhood HSCT to maintain levels in a therapeutic range during the peri-transplantation period...

Within the wide spectrum of symptoms and alteration of systems that characterizes CeD, several studies indicate a low-level of vitamin D, therefore recent guidelines suggest its evaluation at the time of diagnosis. This review examines the data from existing studies in which vitamin D has been assessed in CeD patients. Our review indicates that most of the studies on vitamin D in adult CeD report a 25 (OH) vitamin D deficiency at diagnosis that disappears when the patient goes on a gluten-free diet, independently of any supplementation...

INTRODUCTION AND OBJECTIVES: New biomarkers could improve the predictive capacity of classic risk functions. The aims of this study were to determine the association between circulating levels of apolipoprotein A1 (apoA1), apolipoprotein B (apoB), albumin, and 25-OH-vitamin D and coronary events and to analyze whether these biomarkers improve the predictive capacity of the Framingham-REGICOR risk function. METHODS: A case-cohort study was designed. From an initial cohort of 5404 individuals aged 35 to 74 years with a 5-year follow-up, all the participants who had a coronary event (n = 117) and a random group of the cohort (subcohort; n = 667) were selected...

Background and Aims: There is evidence vitamin D may be immunomodulatory and alter faecal microbiota, but results from clinical studies in humans to date have been inconclusive. This study aimed to assess the effect of vitamin D replacement in vitamin D deficient patients with and without ulcerative colitis (UC) on inflammation and faecal microbiota. Methods: Vitamin D was replaced over 8 weeks in patients with active UC (defined by faecal calprotectin ≥100 µg/g), inactive UC (faecal calprotectin <100 µg/g), and non-IBD controls with baseline 25(OH) vitamin D <50 nmol/L, and markers of inflammation and faecal microbiota analysed...

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder caused by complicated interactions between genetic and environmental factors. Clinical trials, including case reports, case-control studies, and a double-blinded randomized clinical study, have suggested that high-dose vitamin D3 regimens may ameliorate the core symptoms of ASD. Vitamin D3 supplementation was effective in about three-quarters of children with ASD. To further investigate the relationship between vitamin D and ASD symptoms in vitamin D-responsive autistic children, changes in symptoms were assessed in three children with ASD who were given vitamin D3 supplementation followed by a long interruption...
