Los inhibidores de la aromatasa son fármacos disponibles por vía oral que inhiben la conversión de la testosterona en estradiol. Los estrógenos desempeñan un papel esencial en la maduración del cartílago de crecimiento y del cierre epifisario, evento que marca el final del proceso de crecimiento esquelético. Por este motivo, los inhibidores de la aromatasa se han probado como una intervención para mejorar la talla en niños y adolescentes de sexo masculino mediante el retraso en la maduración esquelética al disminuir la concentración de estradiol en la placa de crecimiento. Se resumen los resultados de una revisión sistemática Cochrane en la cual se evaluaron la eficacia y la seguridad de los inhibidores de la aromatasa para el tratamiento de la estatura baja en niños.

Objective: Considering the increased fracture risk in early breast cancer patients treated with aromatase inhibitors (AI), we assessed the impact of a preventive intervention conducted by a specialized osteoporosis unit on bone health at AI treatment start., Material and Methods: Retrospective cohort of postmenopausal women who started treatment with AI after breast cancer surgical/chemotherapy treatment and were referred to the osteoporosis unit for a comprehensive assessment of bone health. Bone densitometry and fracture screening by plain X-ray were performed at the baseline visit and once a year for 5 years., Results: The final record included 130 patients. At AI treatment start, 49% had at least one high-risk factor for fractures, 55% had osteopenia, and 39% osteoporosis. Based on the baseline assessment, 79% of patients initiated treatment with bisphosphonates, 88% with calcium, and 79% with vitamin D. After a median of 65 (50-77) months, 4% developed osteopenia or osteoporosis, and 14% improved their densitometric diagnosis. Fifteen fractures were recorded in 11 (8.5%) patients, all of them receiving preventive treatment (10 with bisphosphonates). During the follow-up period, patients with one or more high-risk factors for fracture showed a greater frequency of fractures (15% vs. 3%) and experienced the first fracture earlier than those without high-risk factors (mean of 99 and 102 months, respectively; P=0.023)., Conclusions: The preventive intervention of a specialized unit at the start of AI treatment in breast cancer survivors allows the identification of patients with high fracture risk and may contribute to preventing bone events in these patients., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.
