Core Tip
Core Tip: This study analyzed the results of 130 kidney transplant recipients. Of the 52 recipients who underwent graft biopsy and met the study inclusion criteria, 14 had a vitamin D level > 15 ng/mL vs ≤ 15 ng/mL in 38. Although low serum vitamin D level emerged as a risk factor for rejection in univariate analysis, this finding was not confirmed by multivariate analysis. Nonetheless, diagnostic and predictive accuracy is limited when a single test is used, and larger-scale prospective clinical studies are needed to clearly discern the effects of serum vitamin D level on the renal allograft rejection rate.
