Hauser Barbara , Riches Philip , Gilchrist Tamara , Wilson Jim F , Fraser William D , Ralston Stuart H

Introduction: Osteoporosis and fragility fractures are recognized complications of rheumatoid arthritis (RA). Previously Riches et al. described a patient with celiac disease and severe osteoporosis in whom neutralizing antibodies to osteoprotegerin (OPG) were present.

FGF23 and vitamin D metabolism in chronic kidney disease – mineral bone disorder

Piec Isabelle , Chipchase Allison , Nicholls Holly , Washbourne Christopher , Tang Jonathan , Fraser William D.

Fibroblast growth factor-23 (FGF23) is a major regulator of phosphate metabolism often elevated in genetic hypophosphataemic disorders and in chronic kidney disease–bone mineral disorder (CKD–BMD). Recent studies have identified relationships between FGF23 and vitamin D.Objectives: To determine the relationship between vitamin D and FGF23 metabolism in CKD.Method: We used randomized samples from patient...
