Tratamiento de la osteoporosis grave con teriparatide / Severe osteoporosis treatment with teriparatide

El objetivo de este trabajo retrospectivo fue evaluar el tratamiento de la osteoporosis grave con teriparatide (PTH) y comparar nuestros resultados con los publicados en la literatura médica. Se incluyeron cuarenta y seis pacientes, cuarenta y dos mujeres y cuatro varones, edad: 69.15 ± 9.43 años. Seis eran vírgenes de tratamiento y cuarenta tratados previamente con bisfosfonatos. Treinta y dos pacientes habían tenido 93 fracturas de las cuales 86 vertebrales. Cuarenta y seis recibieron PTH 6 meses, 29 pacientes durante 12 meses y 20 completaron los 18 meses sugeridos. La densidad mineral ósea (DMO) de columna lumbar aumentó significativamente desde el primer control a los 6 meses (p < 0.0001). La DMO de cuello de fémur alcanzó un incremento significativo al final del tratamiento (p = 0.002). La osteocalcina aumentó significativamente al mes, seguido por el ß crosslaps (beta-CTx, prueba en suero) al tercer mes y la fosfatasa alcalina ósea, regresando los marcadores de recambio óseo a niveles basales a los 18 meses. Las calcemias y las calciurias no se modificaron significativamente, pero 8 pacientes tuvieron hipercalcemias leves y tres hipercalciurias asintomáticas. El tratamiento fue bien tolerado y no se registraron efectos adversos graves que requirieran suspender el tratamiento. En conclusión, la PTH es una alternativa útil y segura para el tratamiento de la osteoporosis grave. Nuestros resultados concuerdan con los previamente publicados en la literatura médica.(AU)

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.(AU)

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.
