Background & aims. - End-stage chronic liver disease is associated with vitamin D deficiency but the prevalence across a broad-spectrum of liver disease is unknown. This study prospectively examines prevalence of vitamin D deficiency and response to replacement in chronic liver disease. Methods. - One hundred and fifty-eight outpatients with chronic liver disease were enrolled. Serum 25-hydroxyvitamin D (25[OH] D) levels were classified as: severely deficient less than 25 nmol/l, deficient 25-54 nmol/l or replete greater than 54 nmol/l. Sixty-five of 158 (41%) had cirrhosis. Results. - 25[OH] D was suboptimal in 101/158 (64%), including severe deficiency in 24 patients (15%). Vitamin D deficiency occurred in liver disease of all aetiologies, including patients with only mild liver disease. 25[OH] D increased by 60.0% (19.11+/-13.20 nmol/l) in patients with deficiency after vitamin D replacement and decreased by 25.2% (-18.33+/-12.02 nmol/l) in non-treated initially replete patients over a median of 4 months. Conclusions. - Vitamin D deficiency improves with oral vitamin D supplementation and levels fall without supplementation. Chronic liver disease patients are at very high risk of vitamin D deficiency regardless of etiology or severity. Crown Copyright (C) 2010 Published by Elsevier Masson SAS. All rights reserved.
