In this study, we aimed to investigate the effect of long-term administration of alendronate to treat bone loss in renal transplant patients.Eighty-two renal transplant recipients were divided into 3 groups. Group 1 included patients who were treated with calcium, vitamin D3, and alendronate; group 2 included patients who were treated with calcium and vitamin D3; and group 3 included patients who did not receive these medications. All patients' sociodemographic data, biochemical parameters, and bone mineral density (BMD) measurements were recorded.There were no significant differences between sociodemographic and laboratory findings at the beginning of study in all groups. The BMD of lumbar spine and femoral neck was significantly less in group 1 at the beginning, 12 and 24 months of the study when compared with other group. At 12 and 24 months of the study, the BMD levels were decreased both group 2 and group 3, whereas in group 1, it was stable at 12 months and increased thereafter. In group 1, the initial femoral neck BMD was negatively correlated with parathormone, sex, and body mass index, and positively correlated with creatinine level. While there was a positive correlation between basal body mass index and femur neck BMD in group 2, there was no correlation between baseline parameters, demographic data, and bone mineral density in group 3 patients.In conclusion, bone loss is inevitable despite calcium and vitamin D replacement. However, bone loss can be stopped and even reversed with alendronate therapy. |
