Teriparatide, a recombinant form of parathyroid hormone, is an anabolic agent approved for use in women and men with osteoporosis. However, it is not well studied in people with chronic kidney disease (CKD). We report on a patient with stage 5 CKD treated with dialysis who presented to our clinic with multiple fractures, including bilateral nondisplaced pelvic fractures resulting in chronic pain and interfering with the patient's ability to work. Bone histomorphometry demonstrated low-turnover bone disease, and he was treated with 20µg of teriparatide (subcutaneous injection) every morning for 24 months. Within 6 months of initiating therapy, the patient's pain resolved and he was able to resume work. Serum calcium and phosphate levels remained within reference ranges throughout his treatment, and he sustained no further fractures. During 24 months of treatment, bone mineral density was maintained at the lumbar spine, and there was an increase of 4% at the femoral neck and total hip. A second transiliac bone biopsy demonstrated improvements in static and dynamic parameters of bone formation. In our patient, 24-month treatment with teriparatide was safe and effective; however, larger studies are needed to determine the efficacy of teriparatide in the dialysis-dependent CKD population.
