RESUMO

INTRODUCTION: The aim of this study was to investigate the associations of patient characteristics, bone mineral density (BMD), bone microarchitecture and calculated bone strength with secondary displacement of a DRF based on radiographic alignment parameters. MATERIALS AND METHODS: Dorsal angulation, radial inclination and ulnar variance were assessed on conventional radiographs of a cohort of 251 patients, 38 men and 213 women, to determine the anatomic position of the DRF at presentation (primary position) and during follow-up. Secondary fracture displacement was assessed in the non-operatively treated patients (N = 154) with an acceptable position, preceded (N = 97) or not preceded (N = 57) by primary reduction (baseline position). Additionally, bone microarchitecture and calculated bone strength at the contralateral distal radius and tibia were assessed by HR-pQCT in a subset of, respectively, 63 and 71 patients. OUTCOME: Characteristics of patients with and without secondary fracture displacement did not differ. In the model with adjustment for primary reduction [OR 22.00 (2.27-212.86), p = 0.008], total [OR 0.16 (95% CI 0.04-0.68), p = 0.013] and cortical [OR 0.19 (95% CI 0.05-0.80], p = 0.024] volumetric BMD (vBMD) and cortical thickness [OR 0.13 (95% CI 0.02-0.74), p = 0.021] at the distal radius were associated with secondary DRF displacement. No associations were found for other patient characteristics, such as age gender, BMD or prevalent vertebral fractures. CONCLUSIONS: In conclusion, our study indicates that besides primary reduction, cortical bone quality may be important for the risk of secondary displacement of DRFs.

RESUMO

This study aimed to gain insight in specific characteristics and beliefs of FLS non-responders. INTRODUCTION: The proportion of non-responding fracture liaison service (FLS) invitees is high but characteristics of FLS non-responders are unknown. METHODS: We contacted FLS non-responders by telephone to consent with home visit (HV) and to fill in a questionnaire or, if HV was refused, to receive a questionnaire by post (Q), to gain insight in beliefs on fracture cause and subsequent fracture risk. RESULTS: Out of 716 FLS invitees, 510 attended, nine declined, and 197 did not respond. Of these non-responders, 181 patients were consecutively traced and phoned until 50 consented with HV. Forty-two declined HV but consented with Q. Excluded were eight Q-consenters in whom no choice was offered (either HV or Q) and 81 patients who declined any proposition (non-HV|Q). 62% HV and Q could recall the FLS invitation letter. The fracture cause was differently believed between HV and Q; the fall (96% versus 79%, p = .02), bad physical condition (36% versus 2%, p = .0001), dizziness or imbalance (24% versus Q 7%, p = .03), osteoporosis (16% versus 2%, p = .02), and increased fracture risk (26% versus 17%, NS). Age ≥ 70, woman, and major fracture were significantly associated with HV consent compared to Q (OR 2.7, 2.5, and 2.4, respectively) and HV compared to non-HV|Q (OR 16.8, 5.3, and 6.1). CONCLUSION: FLS non-responders consider fracture risk as low. Note, 50 patients (about 25%) consented with a home visit after one telephone call, mainly older women with a major fracture. This non-responder subgroup with high subsequent fracture risk is therefore approachable for secondary fracture prevention.

RESUMO

Chronic kidney disease (CKD) is a risk factor for fractures. However, in hip fracture patients, CKD G3-G5 was associated with a higher mortality risk and not associated with a higher risk of subsequent non-hip fractures compared to eGFR > 60 ml/min. The higher mortality risk may, as competing risk, explain our findings. INTRODUCTION: Chronic kidney disease (CKD) is a known risk factor for fragility fractures. Patients aged 50+ with a recent fragility fracture have an increased risk of subsequent fractures. Our aim was to evaluate the association between CKD stages G3-G5 versus estimated glomerular filtration rate (eGFR) > 60 ml/min and the risk of a new non-hip fracture or fragility fracture in patients with a first hip fracture. METHODS: Population-based cohort study using the UK general practices in the Clinical Practice Research Datalink. Associations between CKD stage and first subsequent fracture were determined using Cox proportional hazard analyses to estimate hazard ratios (HRs). To explore the potential competing risk of mortality, cause-specific (cs) HRs for mortality were estimated. RESULTS: CKD G3-G5 was associated with a lower risk of any subsequent non-hip fracture (HR: 0.90, 95%CI: 0.83-0.97), but not with the risk of subsequent major non-hip fragility fracture. CKD G3-G5 was associated with a higher mortality risk (cs-HR: 1.05, 95%CI: 1.01-1.09). Mortality risk was 1.5- to 3-fold higher in patients with CKD G4 (cs-HR: 1.50, 95%CI: 1.38-1.62) and G5 (cs-HR: 2.93, 95%CI: 2.48-3.46) compared to eGFR > 60 ml/min. CONCLUSIONS: The risk of a subsequent major non-hip fragility fractures following hip fracture was not increased in patients with CKD G3-G5 compared to eGFR > 60 ml/min. Mortality risk was higher in both hip fracture and non-hip fracture patients with CKD G4 and G5. The higher mortality risk may, as competing risk, explain our main finding of no increased or even decreased subsequent fracture risk after a hip fracture in patients with CKD G3-G5.

RESUMO

INTRODUCTION: Diagnosing scaphoid fractures remains challenging. High-resolution peripheral quantitative computed tomography (HR-pQCT) might be a potential imaging technique, but no data are available on its feasibility to scan the scaphoid bone in vivo. METHODOLOGY: Patients (≥18 years) with a clinically suspected scaphoid fracture received an HR-pQCT scan of the scaphoid bone (three 10.2-mm stacks, 61-µm voxel size) with their wrist immobilized with a cast. Scan quality assessment and bone contouring were performed using methods originally developed for HR-pQCT scans of radius and tibia. The contouring algorithm was applied on coarse hand-drawn pre-contours of the scaphoid bone, and the resulting contours (AUTO) were manually corrected (sAUTO) when visually deviating from bone margins. Standard morphologic analyses were performed on the AUTO- and sAUTO-contoured bones. RESULTS: Ninety-one patients were scanned. Two out of the first five scans were repeated due to poor scan quality (40%) based on standard quality assessment during scanning, which decreased to three out of the next 86 scans (3.5%) when using an additional thumb cast. Nevertheless, after excluding one scan with an incompletely scanned scaphoid bone, post hoc grading revealed a poor quality in 14.9% of the stacks and 32.9% of the scans in the remaining 85 patients. After excluding two scans with contouring problems due to scan quality, bone indices obtained by AUTO- and sAUTO-contouring were compared in 83 scans. All AUTO-contours were manually corrected, resulting in significant but small differences in densitometric and trabecular indices (<1.0%). CONCLUSIONS: In vivo HR-pQCT scanning of the scaphoid bone is feasible in patients with a clinically suspected scaphoid fracture when using a cast with thumb part. The proportion of poor-quality stacks is similar to radius scans, and AUTO-contouring appears appropriate in good- and poor-quality scans . Thus, HR-pQCT may be promising for diagnosis of and microarchitectural evaluations in suspected scaphoid fractures.

RESUMO

This questionnaire-based study evaluated the reasons for attendance or non-attendance at the fracture liaison service in patients with a recent fracture. Frailty, male sex, living alone, and low education were associated with non-attendance, and the information perceived by the patient was associated with attendance. INTRODUCTION: The purpose of this study was to evaluate hospital registration- and patient-related factors associated with attendance or non-attendance to the Fracture Liaison Service (FLS). METHODS: Out of 1728 consecutive patients registered with a recent fracture at hospital entry, and after exclusion of 440 patients because of death, residence in a nursing home, already on osteoporosis treatment, or recent DXA, 1288 received an FLS invitation. We evaluated the hospital registration of fractures at entry and exit of the hospital. A questionnaire was sent to all invited patients to evaluate factors related to non-attendance (including age, gender, frailty, living alone, income, education, extrinsic motivations (impact of perceived information) and intrinsic motivations (patient's own perceived views and opinions) and to attendance (personal impact of clinical professionals' advice). RESULTS: There were 278 more hospital exit codes than entry codes. Of the 1288 invited patients, 745 returned analyzable questionnaires (537 attenders and 208 non-attenders). Non-attendance was associated with male gender (OR: 2.08, 95% CI: 1.35, 3.21), frailty (OR: 1.62, CI: 1.08, 2.45), living alone (OR:2.05, CI: 1.48, 2.85), low education (OR: 1.82, CI: 1.27, 2.63), not interested in bone strength (OR: 1.85, CI: 1.33, 2.63), and being unaware of increased subsequent fracture risk (OR: 1.75, CI: 1.08, 2.86). Information perceived by the patient was significantly associated with attendance (OR: 3.32, CI: 1.75, 6.27). CONCLUSION: Fracture entry registration inaccuracies, male gender, frailty, living alone, having low general education, or low interest in bone health and subsequent fracture risk were independently associated with FLS non-attendance. Adequately perceived advice (to have a bone densitometry and attend the FLS) was strongly associated with FLS attendance.

RESUMO

We evaluated the association between prevalent vertebral fractures and bone micro-architecture and strength measured using HR-pQCT in postmenopausal women with a recent non-vertebral fracture visiting the Fracture Liaison Service. The presence and severity of prevalent vertebral fracture reflect generalized bone deterioration. INTRODUCTION: We evaluated the association between prevalent vertebral fractures (VFs) and bone micro-architecture and strength measured using HR-pQCT in postmenopausal women visiting the Fracture Liaison Service. METHODS: In this cross-sectional study in women aged 50-90 with a recent non-vertebral fracture (NVF), VFs were identified on lateral spine images by dual-energy X-ray absorptiometry. Bone micro-architecture and strength were measured at the non-dominant distal radius and distal tibia using HR-pQCT. Linear regression analyses were used to estimate the association between prevalent VFs and HR-pQCT parameters. RESULTS: We included 338 women of whom 74 (21.9%) women had at least one prevalent VF. After adjustment for femoral neck aBMD (FN aBMD) and other parameters, women with at least one prevalent vertebral fracture had significantly lower total and trabecular vBMD and trabecular number (ß - 16.7, - 11.8, and - 7.8 in the radius and - 21.4, - 16.6, and - 7.2 in the tibia, respectively), higher trabecular separation at the radius and tibia (ß 9.0 and 9.3, respectively), and lower cortical thickness and calculated ultimate failure load and compressive bone strength at the tibia (ß - 5.9, - 0.6, and - 10.9, respectively) as compared with those without prevalent VFs. Furthermore, more severe prevalent VFs were associated with even lower total and trabecular vBMD and lower ultimate failure load and compressive stiffness at the radius and tibia, and lower trabecular number and higher trabecular separation at the radius. CONCLUSION: This study indicates that the presence and severity of prevalent VFs reflect generalized bone deterioration in women with a recent NVF, independently of FN aBMD.

RESUMO

In the first year, after an osteoporotic fracture of a hip, forearm, upper arm, or spine, the dispensing rates of antidepressants and benzodiazepines increased significantly. After those fractures, recent and past use of antidepressants and benzodiazepines was associated with increased all-cause mortality; current use was not associated with mortality risk. INTRODUCTION: It remains unclear to what extent use of antidepressants and benzodiazepines is associated with mortality risk after a major osteoporotic fracture (MOF). We aimed to study the cumulative use of antidepressants and benzodiazepines during the year after MOF or hip fracture (HF) and whether the use was associated with mortality. METHODS: A cohort study was performed within the Dutch PHARMO Database Network including all patients aged 65+ with a first record of MOF (hip, humerus, forearm, and clinical vertebral fracture) between 2002 and 2011. Data were analyzed using Cox regression models, adjusted for comorbidities, and concomitant medication use and broken down to index fracture type. RESULTS: A total of 4854 patients sustained a first MOF, of whom 1766 patients sustained a HF. Mean follow-up was 4.6 years, divided in 30-day periods. The cumulative antidepressant and benzodiazepine use during the first year after MOF increased from 10.6 to 14.7% and from 24.0 to 31.4%, respectively. Recent (31-92 days before each follow-up period) and past use (> 92 days before) of antidepressants and benzodiazepines after MOF or HF was associated with an increased all-cause mortality risk but current use (< 30 days before) was not. CONCLUSION: There is a considerable increase in dispensing rate of antidepressants and benzodiazepines in the first year after a MOF. Recent and past use of these medications was associated with all-cause mortality. The finding that current use was not associated with mortality should be further explored and may probably be explained by the healthy survivor's bias.

RESUMO

X-ray, CT and DXA enable diagnosis of vertebral deformities. For this study, level of agreement of vertebral deformity diagnosis was analysed. We showed that especially on subject level, these imaging techniques could be used for opportunistic screening of vertebral deformities in COPD patients. INTRODUCTION: X-ray and CT are frequently used for pulmonary evaluation in patients with chronic obstructive pulmonary disease (COPD) and also enable to diagnose vertebral deformities together with dual-energy X-ray absorptiometry (DXA) imaging. The aim of this research was to study the level of agreement of these imaging modalities for diagnosis of vertebral deformities from T4 to L1. METHODS: Eighty-seven subjects (mean age of 65; 50 males; 57 COPD patients) who had X-ray, chest CT (CCT) and DXA were included. Evaluable vertebrae were scored twice using SpineAnalyzer™ software. ICCs and kappas were calculated to examine intra-observer variability. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the receiver operating characteristic curve (AUROC) were calculated to compare vertebral deformities diagnosed on the different imaging modalities. RESULTS: ICCs for height measurements were excellent (> 0.94). Kappas were good to excellent (0.64-0.77). At vertebral level, the AUROC was 0.85 for CCT vs. X-ray, 0.74 for DXA vs. X-ray and 0.77 for DXA vs. CCT. Sensitivity (51%-73%) and PPV (57%-70%) were fair to good; specificity and NPV were excellent (≥ 96%). At subject level, the AUROC values were comparable. CONCLUSIONS: Reproducibility of height measurements of vertebrae is excellent with all three imaging modalities. On subject level, diagnostic performance of CT (PPV 79-82%; NPV 90-93%), and to a slightly lesser extend of DXA (PPV 73-77%; NPV 80-89%), indicates that these imaging techniques could be used for opportunistic screening of vertebral deformities in COPD patients.

RESUMO

Telephone call intervention did not improve alendronate persistence in Fracture Liaison Service (FLS) patients in this study. A bone turnover marker cut-off point for alendronate persistence is proposed for individual FLS patients. INTRODUCTION: FLS aims to prevent subsequent fractures, which should include improving patients' persistence with prescribed oral bisphosphonates. We studied the influence of telephone calls and the predictive value of changes in bone turnover markers (BTMs) for evaluating persistence with alendronate. METHODS: Postmenopausal women with a recent fracture and osteoporosis who started alendronate were randomized to receive three phone calls (PC) (after 1, 4, and 12 months) or no phone calls (no PC). s-CTX and P1NP were measured at baseline and after 3, 6, 9, and 12 months. As a reference group, 30 postmenopausal osteopenic patients with a recent fracture were analyzed as well. Persistence was assessed using the Dutch National Switch Point Pharmacies-GPs database and cross-referenced with PC, no PC, and BTM changes. Cut-off values of BTMs were calculated based on least significant change (LSC) and also on underrunning median values of the untreated osteopenic postmenopausal reference group with a recent fracture. RESULTS: Out of 119 patients, 93 (78%) completed 12 months follow-up (45 PC and 48 no PC). Mean age was 69 years. Persistence was similar in PC and no PC participants. The cut-off value > 29% (< 415 ng/L) as LSC of s-CTX and > 36% (< 53.1 µg/L) as LSC of P1NP was determined optimally showing alendronate persistence after 1 year (being 93 and 88%, respectively). CONCLUSIONS: In this context, telephone calls did not improve persistence. In around 90% of patients, 1-year alendronate persistence was confirmed by achieving LSC of s-CTX and of P1NP at 12 months.

RESUMO

In this cross-sectional study, two-thirds of Fracture Liaison Service (FLS) patients had comorbidities and medications associated with increased bone- or fall-related fracture risk. Bone-related and fall-related fracture risk (BRR and FRR) were associated with age and fracture type, but not with gender or BMD. Systematic evaluation of these factors leads to a more profound assessment in FLS care. INTRODUCTION: This study is a systematic evaluation of comorbidities and medications associated with increased fracture risk in patients aged 50-90 years with a recent fracture visiting the FLS. METHODS: In this cross-sectional cohort study, comorbidities were classified according to ICD-10 and medications according to the Anatomic Therapeutic Chemical (ATC) classification and further categorized into those associated BRR and FRR. RESULTS: Of 1282 patients (72% women; 65 ± 9 years), 53% had at least one BRR, 46% had at least one FRR, and 66% at least one BRR and/or FRR. At least one BRR, as well as at least one FRR were associated with age, BMI, and fracture type, but not with gender or BMD. The proportion of patients with only BRR (± 20%) or only FRR (± 10%) was similar among ages, gender, BMI, fracture type, and BMD. The combination of at least one BRR and at least one FRR was significantly associated with age, BMI, and major fractures, but not with gender or BMD. CONCLUSION: Comorbidities and medications associated with increased fracture risk are present in two-thirds of patients visiting the FLS. In addition, the proportion of patients having a combination of BRR and FRR increased significantly with age, BMI, and fracture severity. This indicates that systematic evaluation of these factors is important for a more profound assessment of subsequent fracture risk in FLS care.

RESUMO

We studied the incidence of subsequent fractures in persons of 50+ years from 1990 to 2012 and the relative risk (RR) of subsequent fractures after an index femur/hip fracture, stratified per 5-year age band. Patients suffering a fracture have a high incidence of a subsequent fracture; the RR of subsequent fracture after a femur/hip fracture ranged from 2 to 7. INTRODUCTION: Recent information on the risk of subsequent fractures after a broad range of index fractures in the UK population is scarce. We therefore studied the rates of subsequent fractures of the femur/hip, humerus, radius/ulna, vertebrae, rib, or pelvis after fractures at one of these sites from 1990 to 2012 in 3,156,347 UK men and women aged 50 years or over. METHODS: We undertook a retrospective observational study using the UK Clinical Practice Research Datalink (CPRD). The incidence of subsequent fractures at a specific site was calculated by dividing the observed number of fractures by the number of person-years (py) at risk. The relative risk (RR) of subsequent fractures after a femur/hip fracture, by 5-year age band, was calculated by dividing the incidence of a specific subsequent fracture type by the incidence of first fractures at the same site in the same age group. RESULTS: The highest subsequent fracture incidence after a femur/hip fracture was for humerus fracture in men (59.5/10.000 py) and radius/ulna fracture in women (117.2/10.000 py). After an index fracture of the radius/ulna, humerus fracture in men (59.3/10.000 py) and femur/hip fracture in women (82.4 per 10.000 py) were most frequent. The RR of fractures after a femur/hip fracture ranged from 2 to 7 and were highest in men and younger age groups. CONCLUSION: Patients suffering a fracture have a high incidence of a subsequent fracture. Our findings demonstrate the importance of fracture prevention in patients with a history of a fracture by adequate medical diagnosis and treatment.

RESUMO

In this small cross-sectional study of predominantly well-treated participants with relatively short-term type 2 diabetes duration, HbA1c > 7% (53 mmol/mol) was associated with lower cortical density and thickness and higher cortical porosity at the distal radius, lower trabecular thickness at the distal tibia, and higher trabecular number at both sites. INTRODUCTION: To examine the association between diabetes status and volumetric bone mineral density (vBMD), bone microarchitecture and strength of the distal radius and tibia as assessed with HR-pQCT. Additionally-in participants with type 2 diabetes (T2DM), to examine the association between HbA1c, diabetes duration, and microvascular disease (MVD) and bone parameters. METHODS: Cross-sectional data from 410 (radius) and 198 (tibia) participants of The Maastricht Study (mean age 58 year, 51% female). Diabetes status (normal glucose metabolism, prediabetes, or T2DM) was based on an oral glucose tolerance test and medication history. RESULTS: After full adjustment, prediabetes and T2DM were not associated with vBMD, bone microarchitecture, and strength of the radius and tibia, except for lower trabecular number (Tb.N) of the tibia (- 4%) in prediabetes and smaller cross-sectional area of the tibia (- 7%) in T2DM. In T2DM, HbA1c > 7% was associated with lower cortical vBMD (- 5%), cortical thickness (- 16%), higher cortical porosity (+ 20%) and Tb.N (+ 9%) of the radius, and higher Tb.N (+ 9%) and lower trabecular thickness (- 13%) of the tibia. Diabetes duration > 5 years was associated with higher Tb.N (+ 6%) of the radius. The presence of MVD was not associated with any bone parameters. CONCLUSIONS: In this study with predominantly well-treated T2DM participants with relatively short-term diabetes duration, inadequate blood glucose control was negatively associated with cortical bone measures of the radius. In contrast, trabecular number was increased at both sites. Studies of larger sample size are warranted for more detailed investigations of bone density and bone quality in patients with T2DM.

RESUMO

We evaluated the impact of a new Dutch guideline on systematic implementation of densitometric Vertebral Fracture Assessment (VFA) in patients with a recent non-vertebral fracture. Systematic implementation resulted in a significant increase of VFA, diagnosis of vertebral fractures (VFs), and percentage of patients eligible for treatment. INTRODUCTION: VFs are underdiagnosed although they are important predictors of fracture risk, independent of age and bone mineral density (BMD). The Dutch guideline on osteoporosis and fracture prevention recommends VFA in all patients aged >50 years with a recent non-VF. Our aim was to evaluate the effect of systematic implementation of densitometric VFA in patients with a recent non-VF at the fracture liaison service (FLS). METHODS: VFA was performed on lateral images of the spine using dual-energy X-ray absorptiometry (DXA) and graded according to Genant using Spine Analyzer software. RESULTS: We evaluated 582 patients before and 484 after implementation (mean age 67 and 66 years; 71 and 74% women, respectively). Performing VFA increased from 4.6 to 97.1% (p < 0.001) and the diagnosis of VFs from 2.2 to 26.2% for grade ≥ 1 (p < 0.001) and from 0.9 to 14.7% for grade ≥ 2 (p < 0.001). Prevalence of VFs increased with age (5.2% in 50-59-year olds to 27.8% in 80+-year olds, p < 0.001), but was similar for both genders, non-VF locations, and BMD. Including patients with osteopenia and a VF increased the percentage of patients eligible for treatment by a quarter, from 31.0% in the pre-guideline to 38.4% in the post-guideline cohort. CONCLUSIONS: Systematic guideline implementation resulted in a significant increase of VFA, diagnosis of VFs, and percentage of patients eligible for treatment. VFA contributes to documenting the high prevalence of VFs in patients visiting the FLS with a non-VF in both genders, at any age, non-VF location, and BMD.

RESUMO

We studied sex-specific incidence rates in a population 50 years or older in the UK. In the period of 1990-2012, the overall rate of fracture did not change, but there were marked secular alterations in the rates of individual fracture types, particularly hip and spine fractures in the elderly. INTRODUCTION: There is increasing evidence of secular changes in age- and sex- adjusted fracture incidence globally. Such observations broadly suggest decreasing rates in developed countries and increasing rates in transitioning populations. Since altered fracture rates have major implications for healthcare provision and planning, we investigated secular changes to age- and sex-adjusted fracture risk amongst the UK population aged 50 years or above from 1990 till 2012. METHODS: We undertook a retrospective observational study using the Clinical Practice Research Datalink (CPRD), which contains the health records of 6.9 % of the UK population. Site-specific fracture incidence was calculated by calendar year for men and women separately, with fracture type categorised according to ICD-9 classification. Linear regression analysis was used to calculate mean annualised change in absolute incidence. For presentational purposes, mean rates in the first 5 years and last 5 years of the period were calculated. RESULTS: Overall fracture incidence was unchanged in both women and men from 1990 to 2012. The incidence of hip fracture remained stable amongst women (1990-1994 33.8 per 10,000 py; 2008-2012 33.5 per 10,000 py; p trend annualised change in incidence = 0.80) but rose in men across the same period (10.8 to 13.4 per 10,000 py; p = 0.002). Clinical vertebral fractures became more common in women (8.9 to 11.8 per 10,000 py; p = 0.005) but remained comparable in men (4.6 to 5.9 per 10,000 py; p = 0.72). Similarly, the frequency of radius/ulna fractures did not change in men (9.6 to 9.6 per 10,000 py; p = 0.25), but, in contrast, became less frequent in women (50.4 to 41.2 per 10,000 py; p = 0.001). Secular trends amongst fractures of the carpus, scapula, humerus, foot, pelvis, skull, clavicle, ankle, patella, and ribs varied according to fracture site and sex. CONCLUSION: Although overall sex-specific fracture incidence in the UK population 50 years or over appears to have remained stable over the last two decades, there have been noticeable changes in rates of individual fracture types. Given that the impact of a fracture on morbidity, mortality, and health economy varies according to fracture site, these data inform the provision of healthcare services in the UK and elsewhere.

RESUMO

UNLABELLED: In this retrospective cohort study using the Clinical Practice Research Datalink (CPRD), patients with sarcoidosis have an increased risk of clinical vertebral fractures and when on recent treatment with oral glucocorticoids, also an increased risk of any fractures and osteoporotic fractures. INTRODUCTION: Sarcoidosis is a chronic inflammatory disease, in which fragility fractures have been reported despite normal BMD. The aim of this study was to assess whether patients with sarcoidosis have an increased risk of clinical fractures compared to the general population. METHODS: A retrospective cohort study was conducted using the CPRD. All patients with a CPRD code for sarcoidosis between January 1987 and September 2012 were included. Cox proportional hazards models were used to derive adjusted relative risks (RRs) of fractures in all sarcoidosis patients compared to matched controls, and within the sarcoidosis group according to use and dose of systemic glucocorticoids. RESULTS: Five thousand seven hundred twenty-two sarcoidosis patients (mean age 48.0 years, 51 % females, mean follow-up 6.7 years) were identified. Compared to 28,704 matched controls, the risk of any fracture was not different in patients with sarcoidosis. However, the risk of clinical vertebral fractures was significantly increased (adj RR 1.77; 95 % CI 1.06-2.96) and the risk of non-vertebral fractures was decreased although marginally significant (adj RR 0.87; 95 % CI 0.77-0.99). Compared to sarcoidosis patients not taking glucocorticoids, recent use of systemic glucocorticoids was associated with an increased risk of any fracture (adj RR 1.50; 95 % CI 1.20-1.89) and of an osteoporotic fracture (adj RR 1.47; 95 % CI 1.07-2.02). CONCLUSIONS: Patients with sarcoidosis have an increased risk of clinical vertebral fractures, and when using glucocorticoid therapy, an increased risk of any fractures and osteoporotic fractures. In contrast, the risk of non-vertebral fractures maybe decreased. Further investigation is needed to understand the underlying mechanisms of these contrasting effects on fracture risk.

RESUMO

In this cohort of relatively young and well-treated participants with type 2 diabetes, we found no association between diabetes status and a history of previous fractures and recent falls. Furthermore, no association between diabetes severity and previous fractures or recent falls was found. INTRODUCTION: In this study, we examined the association between glucose metabolism status and historical fractures or recent falls and the effect of diabetes severity (glucose control, insulin use, and diabetes duration) on falls and fractures in the participants with type 2 diabetes. METHODS: Cross-sectional data from 2005 participants of the Maastricht Study. Falls in the past 6 months and fractures ≥age 50 were assessed by questionnaire. Glucose metabolism status (normal glucose metabolism, impaired glucose metabolism, or type 2 diabetes) was based on the oral glucose tolerance test and medication use. RESULTS: In the completely adjusted model, the odds for a fall were not significantly higher in those with impaired glucose metabolism status (OR (95%CI) 1.28 (0.93-1.77)) or with type 2 diabetes (OR (95%CI) 1.21 (0.80-1.81)) compared with the group with normal glucose metabolism. Within the group with type 2 diabetes, there were no significant differences with regard to reported falls between participants with HbA1c >7 % (53 mmol/mol) versus HbA1c ≤7 % (OR (95%CI) 1.05 (0.58-1.90)), insulin users versus non-insulin users (OR (95%CI) 1.51 (0.79-2.89)), and with a diabetes duration >5 versus ≤5 years (OR (95%CI) 0.52 (0.46-1.47)). Similarly, neither glucose metabolism status nor diabetes severity was associated with prior fractures. CONCLUSIONS: Glucose metabolism status was not significantly associated with previous fractures and recent falls. In addition, in this cohort of relatively young and well-treated participants with type 2 diabetes, diabetes severity was not associated with previous fractures and recent falls.

RESUMO

UNLABELLED: The Fracture Liaison Service (FLS) is advocated to be effective for the prevention of secondary fractures, but implementation is variable. A questionnaire based on the International Osteoporosis Foundation (IOF) Capture the Fracture® FLS standards was used in the current study. The results showed high compliancy with the IOF standards in the Dutch responding hospitals. INTRODUCTION: The FLS is advocated for the prevention of secondary fractures, but its implementation varies between hospitals and countries. The present survey applied the standards proposed by the IOF to evaluate the implementation of FLSs in non-university hospitals in the Netherlands. METHODS: A questionnaire based on the IOF FLS standards was used in this study, requesting the selection, evaluation and treatment data of patients older than 50 years with a recent fracture. RESULTS: Of 90 invited hospitals, 24 (27 %) fully responded, providing data of 24,468 consecutive patients, corresponding with 25 % of fracture patients in the Netherlands in the year 2012. After excluding skull and toe fractures and patients exceeding the upper age limits applied by individual hospitals, 11,983 patient data were available for analysis. The data showed high compliance (>90 %) for fracture patient identification, invitation for FLS, timing of assessment, identification of vertebral fractures, application of national guidelines, evaluation of secondary osteoporosis, drug initiation when indicated, communication with the general practitioner and application of follow-up strategy and 70 % for fall prevention. The response rate was on average (49 %). CONCLUSIONS: The available data also showed that patients attending the FLSs were evaluated, treated and followed in high compliancy with the IOF standards. Some standards are open to different interpretations and may need further specification. The major shortcoming in FLS practice was that patients invited to attend the FLSs showed a low response rate. None of the hospitals achieved the IOF standard patient response rate of over 90 %.

RESUMO

UNLABELLED: The response rate to the invitation to the fracture liaison service and reasons for non-response were evaluated in 2,207 fragility fracture patients. Fifty-one percent responded; non-responders were most often not interested (38 %) or were hip fracture patients. After 1 year of treatment, 88 % was still persistent and 2 % had a new fracture. INTRODUCTION: To increase the percentage of elderly fracture patients undergoing a dual energy x-ray absorptiometry (DXA) measurement, and to investigate why some patients did not respond to invitation to our fracture liaison service (FLS). METHODS: In four Dutch hospitals, fracture patients ≥ 50 years were invited through a written or personal invitation at the surgical outpatient department, for a DXA measurement and visit to our FLS. Patients who did not respond were contacted by telephone. In patients diagnosed with osteoporosis, treatment was started. Patients were contacted every 3 months during 1 year to assess drug persistence and the occurrence of subsequent fractures. RESULTS: Of the 2,207 patients who were invited, 50.6 % responded. Most frequent reasons for not responding included: not interested (38 %), already screened/under treatment for osteoporosis (15.7 %), physically unable to attend the clinic (11.5 %), and death (5.2 %). Hip fracture patients responded less frequently (29 %) while patients with a wrist (60 %) or ankle fracture (65.2 %) were more likely to visit the clinic. In 337 responding patients, osteoporosis was diagnosed and treatment was initiated. After 12 months of follow-up, 88 % of the patients were still persistent with anti-osteoporosis therapy and only 2 % suffered a subsequent clinical fracture. CONCLUSION: In elderly fracture patients, the use of a FLS leads to an increased response rate, a high persistence to drug treatment, and a low rate of subsequent clinical fractures. Additional programs for hip fracture patients are required, as these patients have a low response rate.
