Total 25(<scp>OH</scp>) vitamin D, free 25(<scp>OH</scp>) vitamin D and markers of bone turnover in cirrhotics with and without synthetic dysfunction

Abstract

Cirrhotics with low vs. normal albumin have lower levels of DBP, total and free 25(OH)D. The expected relationship between total or free 25(OH)D with iPTH was observed in normal but not in low albumin cirrhotics, demonstrating that total 25(OH)D is not an accurate marker of bioactive vitamin D status in cirrhotics with synthetic dysfunction. Additional investigation into the role of vitamin D supplementation and its impact on bone mineral homoeostasis in this population is needed.
