We measured the 25(OH)D serum level in 165 patients. Mean age of patients was 49.7 years (range: 11-80). Median time after transplantation was 6.5 years (range 0.8-16.4 years). Mean 25(OH)D level for all cohort was 22.71 ± 7.06 ng/mL; only 30/165 (18%) of patients were vitamin D sufficient. 71/165 (43%) patients showed insufficient 25(OH)D level, 62/165 (38%) patients were mildly vitamin D deficient, and 2/165 (1%) were severely vitamin D deficient.
