Morbilidad de las fracturas vertebrales osteoporóticas durante el aislamiento social en la pandemia COVID-19 / Osteoporotic vertebral fractures morbidity during social isolation on COVID-19 pandemic

Introducción: la pandemia por COVID-19 afectó negativamente los sistemas de salud. Las fracturas vertebrales osteoporóticas y el aislamiento social se relacionan con mayor morbimortalidad. Objetivos: caracterizar la morbilidad de las fracturas vertebrales osteoporóticas y evaluar una posible relación entre morbilidad y nivel de aislamiento social se-cundario al estado de pandemia. Material y métodos: estudio observacional, analítico y transversal. Resultados: se incluyeron en el estudio 45 adultos. La fractura fue mayorita-riamente lumbar con una evolución superior de 3 meses. El 35% presentaba seguimiento, el 48% había recibido tratamiento para osteoporosis y el 48% presentaba fracturas previas documentadas. El 46% refirió falta de accesibilidad al sistema. Se evaluó el aisla-miento social con la escala sociofamiliar de Gijón, que evidenció una situación buena en el 75% y un deterioro social intermedio/severo en el 24%. El Índice de Oswestry mostró una discapacidad mínima/moderada en el 66% y severa o mayor en el 33%. Se evaluó el dolor por la Escala análoga visual (VAS) y se obtuvo un VAS mayor de 5 en el 57%. Al comparar el grupo de situación sociofamiliar buena con el de deterioro social intermedio/severo se observó una diferencia en multipli-cidad de fracturas (p 0,030), hipovitaminosis D (p 0,045) y falta de accesibilidad (p 0,029). En discapacidad y dolor no hubo diferencias. Conclusión: el grupo con mayor aislamiento presentó una enfermedad más severa en términos de multiplicidad de fracturas e hipovitaminosis D; esto podría indicar una asociación entre aislamiento social secundario al estado de pandemia y morbilidad por las fracturas vertebrales.

Introduction: the COVID-19 pandemic had a negative impact on healthcare systems. Osteoporotic vertebral fractures and social isolation have a significant morbidity in our setting. Objectives: to characterize the morbidity of osteoporotic vertebral fractures and evaluate a potential relationship between morbidity and the level of social isolation secondary to the pandemic. Material and methods: observational, analytical and cross-sectional study. Results: forty-five adults were included. Fractures were mostly lumbar with a history of over 3 months. Thirty-five percent (35%) had been followed-up, 48% had been treated for osteoporosis and 48% had previous documented fractures. Forty-six percent (46%) reported lack of accessibility to healthcare. Social isolation was measured using Gijón ́s social-familial evaluation scale, which showed a good situation in 75% of cases and an intermediate/severe social deterioration in 24%. According to the Oswestry index, disability was minimal/moderate in 66% of cases and severe or worse in 33%. Pain was assessed using the Visual Analogue Scale (VAS), with a score greater than 5 recorded in 57% of patients. When comparing the group with a good social-familial situation vs. the group with intermediate/severe social deterioration, differences were found in multiplicity of fractures (p 0.030), hypovitaminosis D (p 0.045) and lack of accessibility (p 0.029). No differences were found in disability and pain. Conclusion: the group with higher levels of isolation exhibited more severe disease in terms of multiplicity of fractures and hypovitaminosis D, which might suggest an association between social isolation secondary to the pandemic and morbidity due to vertebral fractures.

Osteoporotic fractures in rheumatoid arthritis patients in Argentina: a matched retrospective cohort study

Abstract Background: To compare the incidence of osteoporotic fractures in patients with rheumatoid arthritis (RA) with matched controls from a university hospital. Methods: Consecutive RA patients (n = 100) were matched (age and sex) with controls (1:2). The follow-up period began at the index date, defined as the date of diagnosis for RA patients and the date of the first medical claim at the Health Management Organization (HMO) for non-RA patients. Fracture incidence rates per 1000 persons-years (PY) for distinct types of fractures were calculated. Multivariate cox regression analysis was performed to identify factors associated with fractures. Results: One hundred RA patients were followed for a total of 975.1 patients-years and 200 controls for 1485.7 patients-years. No difference was found in the overall fracture incidence rate per 1000 PY between RA and controls (19.5, 95% CI 12.7-28.6 vs 12.1, 95% CI 7.7-18.7, p =0.07). In the Cox regression analysis, only age (HR 1.06, 95% CI 1.02-1.11, p = 0.006) and history of a prior fracture (HR 9.85, 95% CI 2.97-32.64, p < 0.001) were associated with fractures after the index date. The stratified analysis of the fractures by location showed that only the vertebral fractures were more frequent in RA patients compared with controls (12.9 per 1000 PY, 95% CI 8.9-25.8, vs. 3.4, 95% CI 1.4-8.1, respectively, p =0.01). Conclusion: Patients with RA didn't show an overall increased risk of osteoporotic fractures compared with matched controls, but vertebral fractures were more frequently observed in patients with RA.

Manejo subóptimo de fracturas por fragilidad en el Servicio de Traumatología del Hospital de Antofagasta / Suboptimal management of Frailty fractures in Traumatology Service of the Antofagasta Hospital

Existe escasa información respecto al estudio y manejo de la osteoporosis en los pacientes que han sufrido fractura por fragilidad en Chile. Objetivo: Describir la epidemiologia, aproximación diagnóstica y manejo realizado a pacientes hospitalizados por fractura por fragilidad (muñeca, cadera, columna) que ingresaron al Servicio de Traumatología (ST) del Hospital de Antofagasta (HRA). Método: Estudio retrospectivo, se revisó registros de pacientes hospitalizados en ST y se identificó a pacientes que presentaron fractura por fragilidad. Se revisó sus fichas clínicas (período enero 2015-diciembre 2016). Se analizaron factores de riesgos, exámenes realizados, terapias y controles médicos al alta. Resultados: Fueron 971 ingresos y 100 pacientes con fractura por fragilidad. 88% fueron mujeres cuya edad promedio fue 73,1 años. El factor de riesgo más común fue la postmenopausia y antecedente de fractura previa. Las fracturas se distribuyeron en cadera 64%, muñeca 35% y columna 1%. A solo 3 pacientes se le pidió densitometría ósea. En ninguno fue evaluada vitamina D ni PTH. Al 7% se indicó calcio y vitamina D post fractura, a 4% se indicó antiresortivos. En ningún paciente se promovió el consumo de lácteos. Discusión: Las fracturas osteoporóticas en el HRA son inadecuadamente estudiadas para descarte de factores modificables y son farmacológicamente subtratadas, con el riesgo de nueva aparición de fracturas por fragilidad y morbimortalidad asociada. Es importante reforzar en los servicios de traumatología la importancia del manejo médico postfracturas y eventualmente incorporar la participación de otros especialistas en el manejo de estos pacientes durante la hospitalización y al alta.

We have poor information regarding study and management of osteoporosis in patient who have a fragility fracture in Chile. Objetive: Describe epidemiology, diagnostic approach and management performed on patients hospitalized for fragility fracture in Traumatology Service(ST) of the Antofagasta Hospital(HRA). Method: Retrospective study, we reviewed your clinical record (period January 2015-December 2016). Risk factor, laboratory test performed, therapies and medical controls at discharge were analyzed. Resuls: 971 patient admited to ST, 100 were fragility fracture. 88% were women with average age 73,1 years old. The mosts commons risk factors were chronic kidney failure and anticonvulsants treatment. The fractures were 64% of hip, 35% wrist, and 1% column. Only 3 patients have bone densitometry. None had vitamin D or PTH evaluated. Calcium and vitamin D after fracture were indicated at 7%, antiresorptives were indicated at 4%. In none diary consumption were promoted. Discussion: Osteoporotic fractures in HRA are inadequately studied to rule out modifiable factors and they are pharmacologically subtracted, with risk of new fractures an mobility and mortality. Is important remember in the ST importance of the medical management postfracture and the multidisciplinary work.

Servicio de enlace para pacientes con fracturas por osteoporosis / Osteoporotic fracture liaison service

Los pacientes con fracturas por fragilidad presentan elevadas tasas de morbimortalidad, lo que implica además un alto costo para el erario público. Luego de una fractura por osteoporosis, la mayoría de los pacientes no recibe una adecuada evaluación y tratamiento. Para suplir este vacío de atención médica se crearon distintas políticas; la mejor de ellas son los Servicios de Enlace de Pacientes con Fracturas (Fracture Liaison Service, en inglés). Estos programas tienen una vigencia internacional de más de diez años y son patrocinados por organismos internacionales. La finalidad de estos servicios es la prevención secundaria de fracturas. La modalidad de trabajo tiene como objetivo facilitar y asegurar la rápida identificación, el diagnóstico y la terapéutica de esta población en diferentes contextos asistenciales. La experiencia internacional demuestra que estos servicios son exitosos pues logran incrementar el inicio y la adherencia al tratamiento, disminuir las tasas de mortalidad, de morbilidad y de nuevas fracturas, y son costo-efectivos. En nuestro medio, el inicio de los Servicios de Enlace es reciente. El propósito de esta actualización es realizar una revisión de los fundamentos, características, modalidad operativa y los logros obtenidos por dichos programas. Las fracturas por fragilidad ósea constituyen un problema importante para la salud pública. Esta presentación tiene como objetivo alertar y motivar a la comunidad médica a intervenir de manera sistemática y dinámica para mejorar el cuidado habitual en esta población de pacientes. (AU)

Fragility fractures are associated with increased morbidity and mortality rates and higher costs. After a fracture, most patients do not receive adequate assessment and treatment. To fill this gap in medical care, different policies have been created; the best of them being the Fracture Liaison Services. These programs have been in place for over ten years worldwide and are sponsored by international organisms and societies. The purpose of the Fracture Liaison Services is secondary fracture prevention. Their goal is to ensure the rapid identification, diagnosis and treatment of this population in different clinical contexts. They increase treatment adherence and decrease mortality and morbidity rates and the incidence of new fractures. International experience shows that these services are successful and costeffective.

Baseline characteristics of postmenopausal women with osteoporosis treated with teriparatide in a real-world setting in Latin America: a subregional analysis from the Asia and Latin America Fracture Observational Study (ALAFOS)

Abstract Background: Osteoporosis is a major healthcare concern in Latin America. Factors such as changing demographics, fragmented healthcare systems, and financial considerations may result in a huge increase in the burden of osteoporosis in this region. The aim of this article is to describe the baseline clinical characteristics and fracture history of patients who are prescribed teriparatide in normal clinical practice in Latin America. Methods: We conducted a prospective, multinational, observational study (the Asia and Latin America Fracture Observational Study [ALAFOS]) in 20 countries worldwide to assess the incidence of fractures in postmenopausal women with osteoporosis receiving teriparatide as a part of routine clinical practice in a real-world setting. In this subregional analysis of the ALAFOS study, we report the clinical characteristics, fracture history, risk factors for osteoporosis, comorbidities, previous osteoporosis therapies and health-related quality of life measures at baseline for patients from the four participant Latin American countries: Argentina, Brazil, Colombia, and Mexico. Results: The Latin America subregional cohort included 546 postmenopausal women (mean [SD] age: 71.0 [10.1] years; range: 40-94 years), constituting 18% of the ALAFOS total population. The baseline mean (SD) bone mineral density T-scores were - 3.02 (1.23) at the lumbar spine and - 2.31 (0.96) at the femoral neck; 62.8% of patients had a history of low trauma fracture after the age of 40 years and 39.7% of patients had experienced ≥1 fall in the past year. Osteoporosis medications were used by 70.9% of patients before initiating teriparatide. The median (Q1, Q3) EQ-5D-5 L Visual Analog Scale (VAS) scores for perceived health status at baseline was 70 (50, 80). The mean (SD) worst back pain numeric rating scale score for the overall Latin American cohort was 4.3 (3.4) at baseline. Conclusions: This baseline analysis of the Latin America subregion of the ALAFOS study indicates that patients who are prescribed teriparatide in the four participant countries had severe osteoporosis and high prevalence of fractures. They also had back pain and poor health-related quality of life. The proportions of patients with severe or extreme problems on the EQ-5D-5 L individual domains were lower than those in the overall ALAFOS study population.

Functionality, comorbidity, complication & surgery of hip fracture in older adults by age distribution

SUMMARY BACKGROUND Hip fractures may be the greatest complication secondary to osteoporotic disorder. The objective of this study was to determine the influence of age distribution in the functionality, comorbidity, complications and surgical features of older adults with hip fractures. METHODS A prospective cohort study was carried out from 2013 to 2014. A sample of 557 adults over 75 years old with osteoporotic hip fractures was recruited from the Orthogeriatric Unit of the León University Hospital (Spain). Age distributions of 75-84, 85-90 and >90 years old were considered. Firstly, sociodemographic data, fracture type and hospital staying days were collected. Secondly, baseline functionality (Barthel index), ambulation, cognitive impairment and comorbidities were described. Thirdly, surgical intervention, urgency, type, American Association of Anesthesiologists (ASA) scores, non-surgical cause, and baseline pharmacologic treatments were determined. Finally, complications and features at hospital discharge were observed. RESULTS The age ranges did not show any statistically-significant differences (P<.05; R2=.000-.005) for gender, fracture type, or number of hospital staying days. Statistically-significant differences (P<.05; R2=.011-.247) between age groups were observed for Barthel index, cognitive impairment, dementia, osteoporosis, Parkinson's disease, aortic stenosis, surgery type, ASA-score, non-surgical cause, benzodiazepines, antidementia, anti-osteoporosis, insulin, pharmacologic treatments, renal function alteration, heart failure, destination and ambulation features. All other measurements did not show statistically-significant differences (P>.05; R2=.000-.010). CONCLUSION Age distributions greater than 75 years old may determine the functionality, comorbidities, surgical features, baseline pharmacologic treatments, complications and features at hospital discharge for older adults who suffer a hip fracture.

CONCLUSÃO As distribuições de idade após 75 anos podem determinar a funcionalidade, comorbidades, características cirúrgicas, tratamentos farmacológicos de base, complicações e características na alta hospitalar de adultos mais velhos que sofrem fratura de quadril.

Risk of Vertebral Fracture in Patients Diagnosed with a Depressive Disorder: A Nationwide Population-Based Cohort Study

OBJECTIVE: Previous studies have reported that depression may play a crucial role in the occurrence of vertebral fractures. However, a clear correlation between depressive disorders and osteoporotic fractures has not been established. We explored the association between depressive disorders and subsequent new-onset vertebral fractures. Additionally, we aimed to identify the potential risk factors for vertebral fracture in patients with a depressive disorder. METHODS: We studied patients listed in the Taiwan National Health Insurance Research Database who were diagnosed with a depressive disorder by a psychiatrist. The comparison cohort consisted of age- and sex-matched patients without a depressive disorder. The incidence rate and hazard ratios of subsequent vertebral fracture were evaluated. We used Cox regression analysis to evaluate the risk of vertebral fracture among patients with a depressive disorder. RESULTS: The total number of patients with and without a depressive disorder was 44,812. The incidence risk ratio (IRR) between these 2 cohorts indicated that depressive disorder patients had a higher risk of developing a subsequent vertebral fracture (IRR=1.41, 95% confidence interval [CI]=1.26-1.57, p<0.001). In the multivariate analysis, the depressive disorder cohort showed a higher risk of vertebral fracture than the comparison cohort (adjusted hazard ratio=1.24, 95% CI=1.11-1.38, p<0.001). Being older than 50 years, having a lower monthly income, and having hypertension, diabetes mellitus, cerebrovascular disease, chronic obstructive pulmonary disease, autoimmune disease, or osteoporosis were considered predictive factors for vertebral fracture in patients with depressive disorders. CONCLUSIONS: Depressive disorders may increase the risk of a subsequent new-onset vertebral fracture.

Asymptomatic vertebral fractures in patients with low bone mineral density / Fraturas vertebrais assintomáticas em indivíduos com baixa massa óssea

Summary Objective: Vertebral fracture assessment (VFA) is a test technique that can be used to detect asymptomatic vertebral fractures (AVF). It uses dual energy X-ray bsorptiometry (DXA) and can be performed concurrently with bone densitometry. This study aims to assess the prevalence of AVF in patients with low bone mass. Methods: Cross-sectional study including 135 individuals with low bone mineral density (BMD) with a T-score < -2.0 standard deviation (SD) in a densitometry clinic located in the city of Blumenau (state of Santa Catarina). Anthropometric, clinical and lifestyle variables were obtained from history-taking and physical examination. Densitometric variables were obtained by bone mineral densitometry and VFA (Explorer, Hollogic®). Vertebral fractures were classified according to the Genant criteria. Student's t, chi-square and logistic regression were performed for statistical analysis. Results: AVFs occurred in 24.4% of the subjects. They were older compared to those without AVF (65±9.25 versus 60.1±8.66; p=0.005), and had a history of lowimpact fractures (38.24% versus 19.8%; OR 2.5; p=0.03). Half of the patients that reported steroid therapy had AVFs, compared to one fifth of those who did not use steroids (50% versus 21.49%; OR 3.6; p=0.01). Conclusion: Asymptomatic vertebral fractures were present in approximately one fourth of patients. The risk factors associated were history of low-impact fracture, use of steroids and age > 61 years.

Resumo Objetivos: vertebral fracture assessment (VFA) é uma técnica de exame que pode ser aplicada na detecção de fraturas vertebrais assintomáticas (FVA). Utiliza absorciometria de raios-X de dupla energia (DXA) e pode ser realizada concomitantemente ao exame de densitometria óssea. Este estudo visa a avaliar a prevalência de FVA em indivíduos com baixa massa óssea. Métodos: estudo transversal realizado em 135 indivíduos, com baixa densidade mineral óssea (DMO), com T-score < -2,0 desvio padrão (DP), em uma clínica de densitometria de Blumenau (SC). As variáveis antropométricas, clínicas e referentes ao estilo de vida foram obtidas por anamnese e exame clínico; as variáveis densitométricas foram obtidas por DMO e VFA (aparelho modelo Explorer, marca Hollogic®). As fraturas vertebrais foram classificadas de acordo com os critérios de Genant. Os testes estatísticos foram t de student, qui-quadrado e regressão logística. Resultados: FVA ocorreram em 24,4% dos indivíduos. A idade desses indivíduos foi superior à dos indivíduos sem FVA (65±9,25 vs. 60,1±8,66; p=0,005), assim como o antecedente de fratura por baixo impacto (38,24% vs.19,8%; OR 2,5; p=0,03). A metade dos indivíduos que relataram corticoterapia possuíam FVA, contrastando com um quinto dos indivíduos sem corticoterapia (50% vs. 21,49%; OR 3,6; p=0,01). Conclusão: fraturas vertebrais assintomáticas estiveram presentes em aproximadamente um quarto dos pacientes. Os fatores de risco associados foram história de fratura por baixo impacto, corticoterapia e idade > 61 anos.

Fraturas osteoporóticas da coluna vertebral / Osteoporotic fractures spine

As fraturas vertebrais são comuns em idosos e em mulheres no período pós-menopausa. Tais fraturas podem ter como etiologia principal a osteoporose ou ser decorrentes de trauma, infecções ou neoplasia.A osteoporose é caracterizada por diminuição da massa e modificação da microarquitetura óssea, sendo a manifestação mais comum a fratura patológica. Apresenta como manifestação clínica dor, diminuição da altura e desalinhamento da coluna vertebral, sintomas neurológicos, bem como alteração na autoestima e problemas sociais. O diagnóstico de osteoporose é dado por meio da realização de densitometria óssea, sendo esse o padrão-ouro, podendo-se lançar mão de outros métodos de imagemem situações específicas. O tratamento da osteoporose inclui métodos para a prevenção de fraturas, tais como reposição de cálcio e vitamina D, uso de bifosfonados, paratormônio e reposição hormonal. Quando em vigência de fratura, a conduta preferida ainda é a abordagem não cirúrgica, sendo feitapor meio de imobilização, uso de analgésicos, fisioterapia e reabilitação motora. Quando em vigência de déficit neurológico, deformidade severa ou ausência de resposta ao tratamento conservador, está indicada a abordagem cirúrgica.

Vertebral fractures are common in the elderly and in women in the post menopausal period. Such fractures can have as cause osteoporosis or be due to trauma, infection or neoplasia. Osteoporosis is characterized by decreased bone mass and modified microarchitecture, the most common manifestation of a pathological fracture. Presenting clinical manifestation as pain, height loss and misalignment of the spine, neurological symptoms, and change in self-esteem and social problems. The diagnosis of osteoporosis is given by bone densitometry, this being the gold standard, and we can make use of other imaging methods in specific situations. Treatment of osteoporosis includes methods for the prevention of fractures, such as treatment with calcium and vitamin D, use of bisphosphonates, parathyroid hormone and hormone replacement. When in the presence of fracture, the preferred approach is still nonsurgical approach being taken by immobilization, analgesics, physical therapy and motor rehabilitation. Whenin the presence of neurologic deficit, severe deformity or lack of response to conservative treatment require surgical approach.

Association between Bone Mineral Density and Clinical Consequences: Cross-Sectional Study of Korean Postmenopausal Women in an Orthopaedic Outpatient Clinic

This study is to identify the characteristics of BMD and the related clinical consequences through a nationwide, consecutive, cross-sectional study. A total of 1,281 postmenopausal women was enrolled nationwide and underwent measurement for BMD using dual energy x-ray absorptiometry. Following the T-spine and L-spine plane radiography, they were evaluated for vertebral fracture by a semi-quantitative method using the Genant's method. Relationship between BMD and osteoporotic fracture and a degree of deformity in vertebral fracture, treatment history in osteoporosis and the EQ-5D was analyzed. The distribution of the normal, osteopenia and osteoporosis group was 25.9%, 37.0%, and 37.2% in lumbar spine, and 31.4%, 45.3%, and 23.3% in femur neck, respectively. BMD in subjects with symptomatic or asymptomatic vertebral fracture was significantly lower than those without fracture. The femur neck and total hip BMDs were significantly lower in hip fracture group (0.646 g/cm2 and 0.643 g/cm2, respectively) and wrist fracture group (0.661 g/cm2 and 0.712 g/cm2, respectively) than in subjects without fracture (0.721 g/cm2 and 0.712 g/cm2, respectively). The BMD was significantly lower with more severe degree of deformity in vertebral fracture and lower scores in mobility, usual activities and pain/discomfort of the EQ-5D. In Korean postmenopausal women, the prevalence of osteoporosis and vertebral, hip and wrist fracture increase and quality of life decreases with lower BMD.

Percutaneous Vertebroplasty Using Fresh Frozen Allogeneic Bone Chips as Filler

BACKGROUND: Vertebroplasty is not free from cement related complications. If an allograft is used as a filler, most of them can be averted. METHODS: Forty consecutive cases of osteoporotic vertebral fracture were divided into two groups by self-selection. The study and the control groups underwent vertebroplasty with fresh frozen allogeneic bone chips and bone cement, respectively. Clinical results were assessed at preoperation, postoperative day 1 and months 3, 6, and 12 by 10-grade visual analog scale (VAS), and radiological results were assessed at the same time by vertebral kyphotic angle (VKA) and local kyphotic angle (LKA). The results were compared within and between the groups. Survival function was analyzed. The criteria of an event were clinical or radiological deterioration versus pre-index surgery state. RESULTS: VAS was improved in the study group from 8.4 +/- 0.8 to 5.2 +/- 1.4, 6.4 +/- 1.2, 5.5 +/- 2.7, and 3.7 +/- 1.4 at postoperative day 1 and months 3, 6, and 12, respectively, and in the control group from 8.4 +/- 1.2 to 3.2 +/- 1.1, 3.2 +/- 1.7, 3.2 +/- 2.7, and 2.5 +/- 1.7, respectively (within group, p < 0.001; between groups, p < 0.001). VKA was improved in the study group from 18.9degrees +/- 8.0degrees to 15.2degrees +/- 6.1degrees (p = 0.046) and in the control group from 14.7degrees +/- 5.2degrees to 10.3degrees +/- 4.7degrees (p < 0.001) at postoperative day 1. LKA was not improved in the study group but was improved in the control group from 16.8degrees +/- 11.7degrees to 14.3degrees +/- 9.6degrees (p = 0.015). Correction angle was 2.7degrees +/- 4.6degrees, -7.9degrees +/- 5.3degrees, -7.2degrees +/- 5.2degrees, and -7.4degrees +/- 6.3degrees at postoperative day 1 and months 3, 6, and 12, respectively, in the study group and 4.3degrees +/- 3.7degrees, 0.7degrees +/- 3.6degrees, 0.7degrees +/- 4.2degrees, and 0.1degrees +/- 4.4degrees, respectively, in the control group. Correction loss was significant in both groups (p < 0.001) and more serious in the study group (p < 0.001). The 6-month survival rate was 16.7% in the study group and 64.3% in the control group (p = 0.003; odds ratio, 5.250). CONCLUSIONS: In treatment of osteoporotic vertebral fracture, fresh frozen allogeneic bone chips are not recommendable as a filler for its worse results than bone cement.

Factors associated with fragility fractures in women over 50 years of age: a population-based household survey / Fatores associados a fraturas por fragilidade óssea em mulheres acima de 50 anos de idade: um estudo de base populacional

PURPOSE: To analyze the prevalence of and factors associated with fragility fractures in Brazilian women aged 50 years and older. METHODS: This cross-sectional population survey, conducted between May 10 and October 31, 2011, included 622 women aged >50 years living in a city in southeastern Brazil. A questionnaire was administered to each woman by a trained interviewer. The associations between the occurrence of a fragility fracture after age 50 years and sociodemographic data, health-related habits and problems, self-perception of health and evaluation of functional capacity were determined by the χ2 test and Poisson regression using the backward selection criteria. RESULTS: The mean age of the 622 women was 64.1 years. The prevalence of fragility fractures was 10.8%, with 1.8% reporting hip fracture. In the final statistical model, a longer time since menopause (PR 1.03; 95%CI 1.01-1.05; p<0.01) and osteoporosis (PR 1.97; 95%CI 1.27-3.08; p<0.01) were associated with a higher prevalence of fractures. CONCLUSIONS: These findings may provide a better understanding of the risk factors associated with fragility fractures in Brazilian women and emphasize the importance of performing bone densitometry.

OBJETIVO: Analisar a prevalência e os fatores associados a fraturas por fragilidade óssea em mulheres brasileiras com 50 anos ou mais. MÉTODOS: Estudo transversal com base populacional, conduzido de 10 de maio de 2011 a 31 de outubro de 2011, que incluiu 622 mulheres com idade >50 anos, residentes em uma cidade na região Sudeste do Brasil. Foi aplicado um questionário por entrevistadores treinados. As associações entre ocorrência de fraturas por fragilidade óssea após os 50 anos e dados sociodemográficos, hábitos e problemas de saúde, autopercepção de saúde e avaliação da capacidade funcional foram realizadas por meio do teste do χ2 e da regressão de Poisson com critério de seleção de variáveis backward. RESULTADOS: A idade média das 622 mulheres foi 64,1 anos. A prevalência de fraturas por fragilidade óssea foi de 10,8%, com 1,8% relatando fratura de quadril. No modelo estatístico final, apresentar maior tempo de menopausa (RP 1,03; IC95% 1,01-1,05; p<0,01) e osteoporose (RP 1,97; IC95% 1,27-3,08; p<0,01) se associaram a maior prevalência de fraturas. CONCLUSÕES: Esses dados podem ajudar a melhorar o conhecimento sobre os fatores associados a fraturas por fragilidade óssea em mulheres brasileiras e enfatizar a importância da realização da densitometria óssea.

OBJECTIVE: To analyze expenditure on treatment for postmenopausal osteoporosis and associated factors on mean per capita expenditure. METHODS: A probabilistic-deterministic linkage between the database of Authorizations for Highly Complex Procedures and the mortality information system was constructed, resulting in a historical cohort of patients using high-cost medications for the treatment of postmenopausal osteoporosis, between 2000-2006. Mean monthly spending on medicines was stratified by age group and described according to demographic and clinical characteristics and the type of drug used. A linear regression model was used to assess the impact of demographic and clinical characteristics on per capita mean monthly expenditure on medicines. RESULTS: We identified 72,265 women who received drugs for the treatment of postmenopausal osteoporosis. The average monthly expenditure per capita in the first year of treatment was $ 54.02 (sd $ 86.72). The population was predominantly composed of women aged 60-69 years old, who had started treatment in 2000, resident in the Southeast of Brazil, who had previously suffered osteoporotic fractures, and Alendronate sodium was the drug most commonly used at baseline. For most of the patients, the same active ingredient remained in use throughout the treatment period. During the program, 6,429 deaths were identified among participants. More than a third of women remained in treatment for up to 12 months. Raloxifen and calcitonin were the therapeutic alternatives with the greatest impact on the average monthly expenditure on medicine using alendronate sodium as a reference standard. CONCLUSIONS: Due to the high impact of the type of drug used on expenditure on medication, it is recommended that criteria for prescribing and dispensing ...

Perfil dos usuários e gastos com medicamentos excepcionais pelo SUS, destinados ao tratamento da osteoporose, em Minas Gerais, 2000-2004 / Users profile and expenses with the high cost medicines in the National Health System of Brazil for the treatment of osteoporosis in Minas Gerais, 2000-2004

Introdução: A osteoporose é uma doença comum, caracterizada por um comprometimento sistêmico da massa óssea e da microarquitetura que resulta em fraturas por fragilidade. Objetivo: Descrever o perfil demográfico e epidemiológico e os gastos envolvidos com o tratamento da osteoporose em indivíduos residentes em Minas Gerais, atendidos pelo Programa de Medicamentos Excepcionais do Sistema Único de Saúde, no período de 2000 a 2004. Métodos: Realizou-se pareamento probabilístico-determinístico de dados provenientes de registros de Autorizações de Procedimentos de Alta Complexidade/Alto Custo (APAC/SIA) e Sistema de Informação sobre Mortalidade (SIM), do DATASUS, identificando- se os indivíduos com diagnóstico com osteoporose e registro de gastos. Resultados: Foram identificados 6.596 pacientes com osteoporose, predominantemente do sexo feminino, idade igual ou superior a 50 anos. Grande parte dos pacientes atendidos iniciou tratamento medicamentoso após a ocorrência de fraturas osteoporóticas e o medicamento mais utilizado no início do tratamento foi o alendronato de sódio. A média de gastos com medicamentos no primeiro ano de tratamento foi de R$73,60±194,89, sendo maior para pacientes com idades entre 10-14, 20-39 e acima de 80 anos; que iniciaram tratamento em 2000, com fraturas osteoporóticas e utilizaram calcitonina e raloxifeno. Conclusão: Maior ênfase deve ser dada à prevenção de fraturas osteoporóticas, afim de que se inicie o tratamento o mais precocemente possível, auxiliando na redução da morbi-mortalidade e dos custos com o tratamento. Além disso, deve-se priorizar a utilização de medicamentos eficazes, seguros e que apresentem baixo custo de tratamento.(AU)

Introduction: Osteoporosis is a common disease characterised by a systemic impairment of bone mass and microarchitecture that results in fragility fractures. Objective: To describe the epidemiological and demographic profile of patients with osteoporosis enrolled at the High Cost Medicines Program and their treatment expenditures, in Minas Gerais, from 2000 to 2004. Methods: We conducted a data probabilistic-deterministic linkage from records of Ministry of Health's databases (DATASUS): Outpatient Information System (APAC/SIA) and Mortality Information System (SIM), identifying individuals diagnosed with osteoporosis and related drug expenditures. Results: We identified 6596 patients with osteoporosis, most of them were female, aged 50 years or more. Most patients started drug treatment after the occurrence of osteoporotic fractures and the drug used was alendronate sodium. The average cost of medication in the first year of treatment was R$73,60±194,89. The higher expenditures were observed for patients aged 10-14, 20-39 and 80 years or more, who started treatment in 2000, with osteoporotic fractures and were treated with calcitonin and raloxifene. Conclusion: Increased emphasis should be placed for the prevention of osteoporotic fractures. Treatment must begin as early as possible, helping to reduce morbidity and mortality and treatment costs. In addition, the use of effective and low cost drugs should be prioritized.(AU)

Association of Paraoxonase 1 (PON1) polymorphisms with osteoporotic fracture risk in postmenopausal Korean women

There is increasing evidence of a biochemical link between lipid oxidation and bone metabolism. Paraoxonase 1 (PON1) prevents the oxidation of low-density lipoprotein (LDL) and metabolizes biologically active phospholipids in oxidized LDLs. Here, we performed association analyses of genetic variation in PON1 to ascertain its contribution to osteoporotic fractures (OFs) and bone mineral density (BMD). We directly sequenced the PON1 gene in 24 Korean individuals and identified 26 sequence variants. A large population of Korean postmenopausal women (n = 1,329) was then genotyped for eight selected PON1 polymorphisms. BMD at the lumbar spine and femoral neck was measured using dual-energy X-ray absorptiometry. Lateral thoracolumbar (T4-L4) radiographs were obtained for vertebral fracture assessment, and the occurrence of non-vertebral fractures (i.e., wrist, hip, forearm, humerus, rib, and pelvis) was examined using self-reported data. Multivariate analyses showed that none of the polymorphisms was associated with BMD at either site. However, +5989A>G and +26080T>C polymorphisms were significantly associated with non-vertebral and vertebral fractures, respectively, after adjustment for covariates. Specifically, the minor allele of +5989A>G exerted a highly protective effect against non-vertebral fractures (OR = 0.59, P = 0.036), whereas the minor allele of +26080T>C was associated with increased susceptibility to vertebral fractures (OR = 1.73, P = 0.020). When the risk for any OFs (i.e., vertebral or non-vertebral) was considered, the statistical significance of both polymorphisms persisted (P = 0.002-0.010). These results suggest that PON1 polymorphisms could be one of useful genetic markers for OF risk in postmenopausal women.

Epidemiology of osteoporotic fractures in Brazil: what we have and what we need: [review] / Epidemiologia de fraturas pela osteoporose no Brasil: o que temos e o que precisamos: [revisão]

The epidemiology of osteoporotic fractures varies widely among countries and is primarily related to differences in the population and utilization of public healthcare services. Since 1994, over 200 studies about osteoporosis and fractures have been conducted in Brazil, among which 60 have described the current epidemiological status. This work is a compilation of studies published in scientific journals (PubMed, MedLine, Lilacs, SciELO Database) with the respective highlights. Overall, these studies show moderate incidence of hip fracture in subjects over 50 years old. However, the prevalence of all types of bone fragility fracture is higher, ranging from 11 percent to 23.8 percent. In addition, there is a high incidence of recurrent falls, which are the main extra-skeletal factor associated with these fractures. According to the national studies, 12 months after femoral fractures, the mortality rate ranged between 21.5 percent and 30 percent, and there was also a high rate of physical impairment, deterioration of the quality of life and excessive burden to the healthcare system. Considering its high prevalence and associated mortality and physical impairment, osteoporosis and its main consequence, bone fragility fractures, must be considered a major public health problem in our country.

A epidemiologia das fraturas por osteoporose varia amplamente entre os países, principalmente em decorrência das diferenças entre as populações e da utilização de recursos públicos de saúde. Desde 1994, mais de 200 estudos sobre osteoporose e fraturas foram feitos no Brasil, dos quais 60 descreveram a situação epidemiológica atual. Esse manuscrito é a compilação de estudos publicados em revistas científicas (PubMed, MedLine, Lilacs, SciELO Database) com seus principais achados. Em geral, esses trabalhos mostram moderada incidência de fratura de quadril em indivíduos acima de 50 anos de idade. No entanto, a prevalência de todos os tipos de fratura por fragilidade óssea é elevada, variando de 11 por cento a 23,8 por cento. Além disso, é observada alta incidência de quedas recorrentes, um dos principais aspectos extraesqueléticos associados com essas fraturas. De acordo com os estudos nacionais, 12 meses após a fratura de fêmur, a taxa de mortalidade variou de 21,5 por cento a 30 por cento, com elevada taxa de incapacidade física, deterioração da qualidade de vida e grande impacto sobre o sistema de saúde. Diante da elevada prevalência, associação com mortalidade e incapacidade física, a osteoporose e sua principal consequência, a fratura por fragilidade óssea, deveriam ser consideradas um problema de saúde pública em nosso país.

A Comparison of Three Different Guidelines for Osteoporosis Treatment in Patients with Rheumatoid Arthritis in Korea

BACKGROUND/AIMS: Osteoporotic fractures are an important comorbidity with rheumatoid arthritis (RA). We determined the overall fracture risk as assessed by the World Health Organization (WHO)'s FRAX(R) tool in Korean patients with seropositive RA. Additionally, we compared treatment eligibility according to the criteria of the Korean Health Insurance Review Agency (HIRA), FRAX, and the National Osteoporosis Foundation (NOF). METHODS: Postmenopausal women and men > or = 50 years of age with seropositive RA were recruited from one rheumatism center in Korea. The FRAX score was estimated using the Japanese model. Patients were classified as eligible for treatment using the HIRA, NOF, and FRAX thresholds for intervention. RESULTS: The study of 234 patients included 40 men (17%). The mean age was 60 +/- 9 years, and 121 (52%) patients had osteoporosis according to the WHO criteria. The overall median 10-year fracture risk was 13% for major osteoporotic fractures and 3.5% for hip fractures. HIRA guidelines identified 130 patients (56%) eligible for treatment, FRAX included 126 patients (54%), and 151 patients (65%) were included according to NOF guidelines. Older patients with a greater number of risk factors were included by FRAX compared to HIRA. The overall concordance between HIRA and FRAX, expressed as the kappa index, was 0.67, but was as low as 0.44 when limited to patients > or = 60 years of age. CONCLUSIONS: One-half of the patients had osteoporosis requiring treatment. RA patients have a high risk of fracture, and the adoption of a risk-scoring system should be considered.
