The primary objective of this retrospective study was to evaluate the treatment of severe osteoporosis with teriparatide (PTH) and to compare our results with those published in the literature. We included 46 patients, 42 women and four men, mean age: 69.15 ± 9.43 years. Six patients were treatment naive and forty previously treated with bisphosphonates. Thirty-two patients had had 93 fractures of which 86 vertebral. Forty-six received PTH for 6 months, twenty-nine for 12 months and twenty completed the 18 months suggested. Bone mineral density (BMD) of the lumbar spine increased significantly at the first control performed at six months of treatment (p < 0.0001), and the femoral neck BMD reached a significant increase at the end of treatment (p = 0.002). Serum osteocalcin values significantly increased from the first month of treatment, followed by ß crosslaps (beta-CTx, serum test) and bone-specific alkaline phosphatase, returning all the markers of bone turnover to baseline levels at 18 months. Serum and urinary calcium did not change significantly at any time, but 8 (17.9%) patients developed mild hypercalcemia and 3 (6.5%) asymptomatic hypercalciuria. The treatment was well tolerated and there were no serious adverse events requiring discontinuation. In conclusion, PTH is a safe and useful alternative for the treatment of primary severe osteoporosis. Our results agree with those previously reported in the literature.
