Association between serum vitamin D and parathyroid hormone levels in Turkish patients with colonic polyps (original) (raw)

Acta gastro-enterologica Belgica

Abstract

Epidemiological and investigational studies have proved that vitamin D is important in autoimmune processes and has anticancerogenic properties. But the interplay between serum vitamin D and parathyroid hormone (PTH) in colorectal polyps has been less clearly put forward. We evaluated serum vitamin D, PTH levels in Turkish people and tried to stratify colorectal polyps according to risk factors. Patients undergoing colonoscopy between January 2012 and March 2012 were considered to study serum vitamin D levels during winter. Study population comprised of 98 colorectal polyp and 197 normal colonoscopy patients. Serum vitamin D levels were not different between the groups (mean vitamin D level in polyp group 14.3 ± 11.1 vs. 12.7 ± 6.74 the normal group, p = 0.12). Likewise serum PTH levels were not different between the groups Patients with polyps were further classified as high and low risk polyps. When discriminant function analysis was conducted, the effects of vitamin D or PTH leve...
