Fat-soluble Vitamin Deficiencies and Inflammatory Bowel Disease: Systematic Review and Meta-Analysis.

Fat-soluble Vitamin Deficiencies and Inflammatory Bowel Disease: Systematic Review and Meta-Analysis. J Clin Gastroenterol. 2017 Aug 30;: Authors: Fabisiak N, Fabisiak A, Watala C, Fichna J Abstract BACKGROUND: Vitamin deficiency is frequently associated with inflammatory bowel disease (IBD). Supplementation of vitamins could thus serve as an adjunctive therapy. The present meta-analysis reviews the deficiencies and alterations in serum fat-soluble vitamins (A, D, E, and K) reported in IBD patients. MATERIALS AND METHODS: PubMed database search was performed to identify all primary studies up to January 2015 that evaluated the serum…

Vitamin D Status Is Associated with Hepcidin and Hemoglobin Concentrations in Children with Inflammatory Bowel Disease.

Vitamin D Status Is Associated with Hepcidin and Hemoglobin Concentrations in Children with Inflammatory Bowel Disease. Inflamm Bowel Dis. 2017 Jul 11;: Authors: Syed S, Michalski ES, Tangpricha V, Chesdachai S, Kumar A, Prince J, Ziegler TR, Suchdev PS, Kugathasan S Abstract BACKGROUND: Anemia, iron deficiency, and hypovitaminosis D are well-known comorbidities in inflammatory bowel disease (IBD). Epidemiologic studies have linked vitamin D deficiency with increased risk of anemia, and in vitro studies suggest that vitamin D may improve iron recycling through downregulatory effects on hepcidin and proinflammatory cytokines. METHODS:…
