Bone mineral density and fat-soluble vitamin status in adults with cystic fibrosis undergoing lung transplantation: A pilot study

Abstract

Purpose: Patients with cystic fibrosis (CF) often experience low bone mineral density (BMD) pre- and post-lung transplantation (LTX). The study purpose was to describe BMD and micronutrient status in adults with CF pre- and post-LTX. Methods: Twelve patients with CF (29 ± 8 years) were recruited from the CF clinic at the University of Alberta Lung Transplant Program. BMD and vitamins A, D, E, K status, and parathyroid hormone were measured pre- and post-LTX. Results: No significant differences pre- and post-LTX were observed at the different bone sites measured (lumber-spine, femoral-neck (FN), hip, and femoral-trochlea) (P > 0.05). BMD T-scores ( 3 ng/mL) pre- and post-LTX. Conclusion: Adults with CF pre- and post-LTX had reduced BMD and suboptimal vitamin K status.
