Osteopenia after transplantation is a significant cause of morbidity.
Despite the lack of randomized, placebo-controlled trials in renal tra
nsplantation, there is literature supporting both the prevention and t
reatment of existing corticosteroid-induced osteoporosis with antireso
rptive agents, such as calcitonin and bisphosphonates. The newer pharm
acologic agents, nasal spray calcitonin and alendronate, have shown pr
omising results in postmenopausal osteoporosis, and their ease of admi
nistration and low incidence of side effects make them ideal for renal
transplant patients.
