Method: We performed a cross-sectional study in 727 stable recipients from 28 Spanish transplant clinics. Mineral metabolism parameters, the semi-quantification of vertebral fractures and abdominal aortic calcifications were determined centrally. Results: Vitamin D deficiency (250HD(3) <15 ng/ml) was more common in female recipients at CKD-T stages I-III (29.6% vs 44.4%; p = 0.003). The inverse and significant correlation between 250HD(3) and PTH was gender-specific and women exhibited a steeper slope than men (p = 0.01). Vertebral fractures (VFx) with deformity grade >= 2 were observed in 15% of recipients. Factors related to VFx differed by gender; in males, age (OR 1.04; 95% CI 1.01-1.06) and CsA treatment (OR: 3.2; 95% CI: 1.6-6.3); in females, age (OR 1.07; 95% CI: 1.03-1.12) and PTH levels (OR per 100 pg/ml increase: 1.27; 95% CI: 1.043-1.542). Abdominal aortic calcifications were common (67.2%) and related to classical risk factors but not to mineral metabolism parameters. Conclusions: Vitamin D deficiency is more common among female kidney transplant recipients at earlier CKD-T stages, and it contributes to secondary hyperparathyroidism. Prevalent vertebral fractures are only related to high serum PTH levels in female recipients. (C) 2016 Sociedad Espanola de Nefrologia.
