Effect of moderate beer consumption (with and without ethanol) on osteoporosis in early postmenopausal women: Results of a pilot parallel clinical trial

Introduction: Osteoporosis is a chronic progressive bone disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to an increase in bone fragility and the risk of fractures. A well-known risk factor for bone loss is postmenopausal status. Beer may have a protective effect against osteoporosis associated with its content of silicon, polyphenols, iso-α-acids and ethanol, and its moderate consumption may therefore help to reduce bone loss in postmenopausal women. Methods: Accordingly, a 2-year controlled clinical intervention study was conducted to evaluate if a moderate daily intake of beer with (AB) or without alcohol (NAB) could have beneficial effects on bone tissue. A total of 31 postmenopausal women were assigned to three study groups: 15 were administered AB (330 mL/day) and six, NAB (660 mL/day), whereas, the 10 in the control group refrained from consuming alcohol, NAB, and hop-related products. At baseline and subsequent assessment visits, samples of plasma and urine were taken to analyze biochemical parameters, and data on medical history, diet, and exercise were collected. BMD and the trabecular bone score (TBS) were determined by dual-energy X-ray absorptiometry. Markers of bone formation (bone alkaline phosphatase [BAP] and N-propeptide of type I collagen [PINP]) and bone resorption (N-telopeptide of type I collagen [NTX] and C-telopeptide of type I collagen [CTX]) were determined annually. Results: Bone formation markers had increased in the AB and NAB groups compared to the control after the 2-year intervention. However, the evolution of BMD and TBS did not differ among the three groups throughout the study period. Discussion: Therefore, according to the findings of this pilot study, moderate beer intake does not seem to have a protective effect against bone loss in early post-menopausal women

Vertebral fracture risk in glucocorticoid-induced osteoporosis: the role of hypogonadism and corticosteroid boluses

Objective: The aim of this study was to identify the risk factors associated with fragility fracture (FF) development in glucocorticoid (GC)-treated patients. Methods: 127 patients (aged 62±18 years, 63% women) on GC-treatment (mean dose 14.5±14.1 mg/day and duration 47.7±69 months) were included. The clinical data collected included bone metabolism study (including gonadal axis), GC-treatment, disease activity, dual-energy X-ray absorptiometry analysis (evaluating densitometric osteoporosis (OP) and trabecular bone score (TBS) degraded microarchitecture values (DMA)), X-ray (assessing vertebral fractures (VF)), FRAX risk (GC-adjusted) and previous FF. Results: 17% of the patients had VF, 28% FF (VF and/or non-VF), 29% OP and 52% DMA. Patients with VF received more GC boluses (57.1% vs 29.5%, p=0.03), were older (68±13 vs 60±19 years, p=0.02), postmenopausal (100% vs 67%, p=0.02), had low testosterone levels (57% vs 11%, p=0.02), lower TBS values (1.119±0.03 vs 1.237±0.013, p100, p=0.01) and having received GC boluses (OR 3.45; 95% CI 1.04 to 12.15, p=0.01) were the main factors related to VF. Hypogonadism (OR 7.03; 95% CI 1.47 to 38.37, p=0.01) and FRAX >20 (OR 7.08; 95% CI 1.28 to 53.71, p=0.02) were factors related to FF. Conclusion: Hypogonadism is the principal risk factor for developing fractures in GC-treated men and women, whereas receiving GC boluses is a major factor for VF. These results indicate the importance of evaluating the gonadal axis in these patients

Riesgo de fractura en la cohorte FRODOS. Estudio comparativo de la aplicación del modelo FRAX® español, francés, inglés y sueco.

Background and objectives: Studies on the validation of FRAX® in Spain show an underestimation of the risk of principal osteoporotic fractures (POFs) and more accurate predictions for femoral fractures (FF). It has been suggested that this algorithm may be improved with more specific data on the epidemiology of these fractures in Spain. The objectives of this work were to describe the baseline risk of fractures according to the Spanish FRAX® model in the participants of the FRODOS cohort, and to compare these data with the application of other European models of FRAX® in the same cohort. Methods: Observational study in a population cohort of 2,968 postmenopausal women (59-70 years of age). The online desktop version of FRAX® was used for multiple data entries to calculate the risk of POFs and FFs at 10 years using the Spanish, French, British and Swedish models in the same cohort. Results: The lowest risk corresponded to the Spanish model: FF: 1.22% (36 expected fractures) and POF: 5.28% (n=197), while the highest risk was for the Swedish model: FF: 3.15% and POF 13.51% (n=401). The models for France and the United Kingdom had intermediate values. Conclusion: In a Spanish cohort of 2,968 postmenopausal women the percentage risk of expected fractures at 10 years increased following a south-north latitude gradient when different European FRAX® models were applied. The results for the incidence of fractures on the FRODOS cohort predicted for the coming years will confirm, or not, the usefulness of this analysis.Fundamento y objetivos: Los estudios sobre validación del FRAX® en España muestran una infravaloración del riesgo de fracturas osteoporóticas principales (FOP) y predicciones más ajustadas para las fracturas femorales (FF). Se ha sugerido que este algoritmo podría mejorarse con datos más concretos de la epidemiología de las fracturas en España. Los objetivos de este trabajo fueron describir el riesgo basal de fracturas según el modelo español FRAX® en las participantes de la cohorte FRODOS y comparar estos datos con la aplicación de otros modelos europeos FRAX® en la misma cohorte. Métodos: Estudio observacional en una cohorte poblacional de 2.968 mujeres postmenopáusicas (59-70 años); se utilizó la versión online desktop de FRAX® para múltiples entradas de datos para calcular los riesgos de FOP y FF a 10 años aplicando los modelos español, francés, inglés y sueco en la misma cohorte. Resultados: El riesgo más bajo correspondió al modelo español: FF: 1,22% (36 fracturas esperadas) y FOP: 5,28% (n=197), mientras que el riesgo más alto fue el del modelo sueco: FF: 3,15% y FOP 13,51% (n=401). Los modelos de Francia y el Reino Unido presentaron valores intermedios. Conclusión: En una cohorte española de 2.968 mujeres postmenopáusicas el riesgo porcentual de fracturas esperadas a 10 años se incrementa con un gradiente de latitud sur-norte al aplicar diferentes modelos FRAX® europeos. Los resultados de incidencia de fracturas en la cohorte FRODOS previsto para los próximos años, confirmarán o no la utilidad del presente análisis

Factores relacionados con la respuesta inadecuada al tratamiento osteoformador (teriparatida/PTH 1–84) en pacientes con osteoporosis severa. Resultados preliminares

The aim of this study was to evaluate the long-term bone mineral density (BMD) response rate to osteoanabolic treatment in patients with severe osteoporosis and the factors related to “inadequate” response (IR). Methods: 49 patients (46F:3M) with a mean age of 69.5±11.1 years treated with teriparatide (41) or PTH1-84 (8) during 18/24months were included (84% had vertebral fractures and 84% had previously received bisphosphonates). Previous skeletal fractures and antiosteoporotic treatment, risk factors and cause of osteoporosis were recorded in all patients. Bone turnover markers (BTM) and 25-OH vitamin D (25OHD) levels were assessed before and at 3, 6, 12 and 18/24 months. Lumbar and femoral BMD and spinal X-ray were assessed at baseline and at 12 and 18/24 months. IR was defined by a lumbar BMD change <3% at 18/24 months. Results: 29% of patients showed IR to therapy. No significant differences were observed in age, baseline BMD and BTM and 25OHD levels between patients with or without IR. 92% of IR patients had been previously treated with bisphosphonates (vs 79%, p=0.34) during 7±4.8 years (vs 4.9±4.2 years, p=0.19). No significant differences were observed between groups in the magnitude of changes in BTM throughout the study. Conclusions: 29% of patients with severe osteoporosis presented IR to osteoanabolic therapy. Although no predictive factors related to this finding were identified, previous prolonged therapy with bisphosphonates may play a role.El objetivo de este estudio ha sido analizar la evolución de la masa ósea a largo plazo tras tratamiento osteoformador (teriparatida o PTH 1-84) en pacientes con osteoporosis severa, y determinar la frecuencia y los factores relacionados con una respuesta inadecuada (RI) al tratamiento. Métodos: Se incluyeron 49 pacientes (46 mujeres:3 hombres) con una edad media de 69,5±11,1 años, tratados con teriparatida (41) o PTH1-84 (8) durante 18/24 meses (84% tenían fracturas vertebrales y 84% habían recibido tratamiento previamente). Se analizaron: factores de riesgo y causa de osteoporosis, fracturas y tratamiento antiosteoporótico previo. Se valoraron los marcadores de recambio óseo (MRO), los niveles de 25-OH vitamina D (25OHD) basal y a los 3, 6, 12 y 18/24 meses, radiografías de columna dorso-lumbar y densitometría ósea (DMO) previa, a los 12 y 18/24 meses. Se definió RI cuando el cambio de DMO lumbar era <3% a los 18/24 meses. Resultados: 29% de los pacientes presentaron RI al tratamiento. No se observaron diferencias en la edad, DMO basal, valores de 25OHD y/o MRO entre los pacientes con y sin RI. El 92% de pacientes con RI había seguido tratamiento previo con bisfosfonatos (vs. el 79% de los pacientes sin RI, p=0,34) durante 7±4,8 años (vs. 4,9±4,2 años, p=0,19). No se observaron diferencias significativas en la evolución de los MRO tras iniciar el tratamiento entre ambos grupos de pacientes. Conclusión: El 29% de los pacientes con osteoporosis grave presenta una RI al tratamiento osteoformador. Aunque no se han identificado factores predictores de este tipo de respuesta, es posible que el tratamiento prolongado previo con bisfosfonatos pueda estar relacionado con este hallazgo

Clinical evolution of sacral stress fractures: influence of additional pelvic fractures

To evaluate the clinical evolution of sacral stress fractures in relation to the scintigraphic pattern and the presence of additional pelvic fractures. METHODS--This was a retrospective study of 14 patients with sacral fractures. RESULTS--Six patients had additional pelvic fractures. Four bone scintigraphic patterns were found. The resolution of symptoms was longer in patients with associated pelvic fractures (30 weeks v three weeks). No relation was found between the bone scintigraphic pattern and the time of evolution. CONCLUSION--Associated pelvic fractures delay the resolution of symptoms in patients with sacral fractures, regardless of scintigraphic pattern
