RESUMEN

Objetivo: Evaluar, a lo largo de un seguimiento de 79,2 meses, el comportamiento de la densidad mineral ósea (DMO) determinada mediante Densitometría Axial Computarizada (DXA), la densidad mineral ósea volumétrica (DMOvol) y su relación con los datos antropométricos, junto con los parámetros relativos al metabolismo óseo (calcio, fósforo, fosfatasa alcalina, parathormona (PTH) y vitamina D (25-OH-D3)) en una población infantil con Diabetes Mellitus Tipo 1 (DM1) sin complicaciones microvasculares y un grupo control de referencia de similares características.Material y métodos: Inicialmente, se realizó un estudio transversal en 40 niños diabéticos (edad media 9,4±2,8 años) y 108 controles (9,3±1,5 años) para valorar las posibles diferencias entre ambas poblaciones. 26 pacientes del grupo diabético inicial, fueron reevaluados tras 79,2 meses de seguimiento.Resultados: Se observó que, al inicio, la masa ósea fue similar en los diabéticos y controles. Después del seguimiento, la DMO de los niños diabéticos era muy inferior a la esperada en población infantil no diabética.El peso, la altura y el Índice de Masa Corporal (IMC) siguieron el mismo patrón que la DMO. Los valores de calcio, fósforo, fosfatasa alcalina, PTH y vitamina D, aunque en rango de normalidad, fueron más bajos que en los controles. La fosfatasa alcalina no se incrementó en el periodo puberal.Conclusiones: El presente estudio demuestra que los niños y adolescentes con un diagnóstico reciente de DM1 tienen una DMO normal. Sin embargo, con el paso del tiempo, y sobre todo durante la adolescencia, muestran una menor ganancia de masa ósea y alteraciones en los parámetros de recambio óseo. (AU)

RESUMEN

OBJECTIVE: To evaluate the incidence of osteoporotic hip fracture in the Macarena Health Area (Seville). SETTING AND PARTICIPANTS: This was a prospective observational study that collected all osteoporotic hip fractures that occurred between March 2013 and February 2014 at the Clinical Unit of Traumatology and Orthopaedics. All cases collected during the first 6 months of the study were followed for 1 year after the occurrence of the event. OUTCOME MEASURES: We evaluated the incidence of osteoporotic hip fractures in the Macarena Health Area (Seville) from 1 March 2013 to 28 February 2014, and we compared the incidence with that in 2 previous studies carried out with the same methodology in 1994 and 2006. Furthermore, we calculated the morbidity and degree of disability 1 year after the fracture occurred and determined mortality and the associated factors. RESULTS: The overall incidence was 228 per 100 000 individuals/year (95% CI 204.5 to 251.6), and the incidence was higher in women than in men. In women, the incidence rate decreased in all age groups over time, while in men, the incidence rate increased. The mortality rate 1 year after the episode was 27.2%. The factors associated with overall mortality were a body mass index below 25 kg/m2, renal failure and low plasma proteins. CONCLUSIONS: Our results show a high incidence of osteoporotic hip fracture that is increasing in men, and in men it is associated with a higher mortality than in women. There is room to improve the modifiable factors associated with mortality and the available rehabilitation interventions to reduce the disability associated with these fractures.

RESUMEN

BACKGROUND/OBJECTIVE: Osteoporosis and osteoporotic fracture risk are extraintestinal manifestations of the inflammatory bowel disease, whose etiopathogenic mechanisms have not been determined yet. Anti-tumor necrosis factor (TNF)-α are used in treatment of inflammatory bowel disease (IBD), but it is unknown if they play a role in osteoporotic fracture prevention. The objective of this study was to know if anti-TNF decreases fracture risk or modifies bone mineral density. To determine the possible risk factors associated with fractures, and assess the incidence of vertebral fractures in IBD patients. METHODS: Longitudinal prospective cohort study (7 yr of follow-up); which included 71 IBD patients, 23 received anti-TNF-α; the remaining 48 received conventional treatment, constituted the control group. Patients participated in a questionnaire which gathered risk factors associated with the development of osteoporosis and fractures. Radiographs of the dorsolumbar-spine were performed and also a bone density measurement. Their biochemical and bone remodeling parameters were determined. RESULTS: Although patients who did not receive anti-TNF-α, suffered more fractures but biologic therapy did not reduce the risk of new vertebral fractures. The increase of bone mass was significantly higher the group treated with anti-TNF-α. The increase in the lumbar spine was of 8% and in the femoral neck was of 6.7%. The only determinant factor for the incidence of vertebral fractures was a history of previous fractures (odds ratio of 12.8; confidence interval 95% 2.37-69.9; p = 0.003). The incidence of vertebral fractures in IBD patients was considerably high: 26.7/700 patient-yr. CONCLUSIONS: Anti-TNF-α, although increased bone mass in these patients, did not reduce the risk of new vertebral fractures. In this study, patients with IBD have a considerably high incidence of fractures. Only the existence of previous vertebral fractures was a predictive factor for consistent fractures.

RESUMEN

BACKGROUND AND AIMS: Osteoporosis has been traditionally considered as a disease in women. However, it is now known that this condition is also important in men. It is a multifactor condition whose main independent risk factor to suffer fractures, in general, and those of the hip, specifically, is bone mass. Nonetheless, there are other independent risk factors of importance. This study has aimed to study if men and women suffer hip fractures with the same bone mass and if they have the same risk factors associated to this condition. PATIENTS AND METHODS: We studied 105 patients with non-traumatic hip fracture and 68 healthy controls. The different risk factors were analyzed, including clinical data, lifestyle, analytic data, data related to bone metabolism and sex hormones as well as a complete bone evaluation. RESULTS AND CONCLUSIONS: Hip bone mass density (BMD) values are the main risk factor for osteoporotic fractures in both genders. These values are comparable when expressed in terms of volumetric density. In women, risk factors that determine the appearance of fractures are previous non-traumatic fractures when they are older than 50 years, total hip BMD, serum calcium levels and thiazide intake while in men only total hip BMD reaches statistical significance.
