Abstract
Introduction
Impaired vitamin K status in cystic fibrosis (CF) has been considered as a newly emerged pathogenetic factor for reduced bone mineral density (BMD).
Objectives
Our aim was to evaluate the effectiveness of vitamin K supplementation in managing bone formation abnormalities in children and adolescents with CF.
Materials and methods
The statuses of vitamins K and D in relation to biochemical markers of bone metabolism and BMD were examined in 20 CF children receiving vitamin D supplements but not vitamin K supplements. Laboratory tests were carried out at the beginning of the study period and after 1 year of vitamin K supplementation (10 mg single oral dose/week) and the results were compared; the results were also compared with those of 25 healthy controls.
Results and discussion
Ten of the CF patients had BMD z-score ≤2.5 (n=5) or between −1 and −2.5 (n=5). Biochemical tests on patients before vitamin K supplementation revealed that the levels of osteoblastic activity markers, namely, bone alkaline phosphatase (BAP), serum osteocalcin (Gla-OC), serum carboxy-terminal propeptide of type I procollagen (PICP) and serum amino-terminal propeptide of type I procollagen (PINP), were significantly reduced compared with those of the controls. These patients had also lower 25-hydroxy-vitamin D (25(OH)D) and vitamin K serum levels, higher undercaboxylated osteocalcin (Glu-OC) and parathormone (PTH) levels and a higher calcium to creatinine ratio (Ca/Cr) than the controls. Vitamin K intake was associated with an increase in Gla-OC, PINP, PICP levels and a decrease in Glu-OC levels. PTH levels were lower after vitamin K supplementation without any difference in BMD z-scores.
Conclusion
Our data indicate that vitamin K supplementation may have a beneficial role in bone health in CF children.
