Abstract

VitD deficiency and bone disease are common after Tx. Prevalence and risk factors for low VitD and BMD and response to VitD therapy were investigated in pediatric renal Tx recipients. 25-hydroxy VitD levels of 71 Tx were compared to 54 healthy AA children. DXA of 44 Tx were compared to 47 AA controls. Of Tx, 59% were AA. Majority (59.1%) of Tx were VitD deficient (23.9%) or insufficient (35.2%). Prevalence of low VitD levels was double in AA (73.9%) vs. non-AA Tx (37.7%), (p = 0.003). Low VitD among Tx was associated with AA ethnicity (p < 0.01), winter (p < 0.05), older age (p < 0.05), males (p < 0.05) and time <6 months post Tx (p < 0.05). Tx with low VitD were treated with oral ergocalciferol or cholecalciferol (23 each); 13% treated with ergocalciferol vs. 82.6% treated with cholecalciferol achieved repletion (p < 0.0001). Of 36 Tx with whole body DXA, 19.5% had BMD (z < -1) after height adjustment. AA Tx had 3.4-fold higher risk of low BMD vs. controls (p < 0.05). Low VitD and BMD are prevalent in children after renal Tx. Better repletion of VitD is achieved with cholecalciferol.
