BACKGROUND: Metabolic consequences resulting from loss of renal mass in living kidney donors remain uncertain. There is recent focus on the changes in the active form of vitamin D because it is an agent for cancer regulation. The objective of the study was to measure serum concentrations of 1,25-dihydroxycholecalciferol, parathyroid hormone and insulin-like growth factor-1 (IGF-1) in living donors after kidney donation. PATIENTS AND METHODS: Forty living kidney donors reported for follow-up visits. Their mean age was 46.14 years. They were women in 52.5% of cases. The mean observation period was 65.6 months. Serum 1,25(OH)2D3 and IGF-1 concentrations were measured by radioimmunoassay after extraction. Serum intact parathyroid hormone (PTH) was quantified using an enhanced chemiluminescence immunoassay system. RESULTS: 1,25-dihydroxycholecalciferol deficiency in 57.5% patients after nephrectomy was the most important change we noted. No correlation was observed between 1,25(OH)2D3 and PTH. A decreased serum IGF-1 concentration was observed in 17.5% of donors. However, decreases in both serum IGF-1 and 1,25(OH)2D3 concentrations were observed in 12.5% of donors. CONCLUSION: Prospective studies may be essential to determine metabolic changes after nephrectomy among living kidney donors.
