ABSTRACT

Objective: While the role of aldosterone in bone metabolism is well established, the specific effects of the widely used aldosterone antagonist, spironolactone, on bone health are not fully understood. This study aimed to investigate the effects of spironolactone on osteoporosis and future fracture risk in middle-aged and elderly hypertensive patients, revealing its potential benefits for bone health. Methods: Propensity score matching was employed in this study to create matched groups of spironolactone users and non-users at a 1:4 ratio. We investigated the association between spironolactone use and the risk of osteoporosis using multivariate logistic regression analysis. Furthermore, we conducted multivariate linear regression analysis to explore the relationship between cumulative dosage and the FRAX score. Subgroup analysis was also performed to assess the effects under different stratification conditions. Results: In both pre-match and post-match analyses, multivariable logistic regression revealed a significant reduction in the risk of osteoporosis in the spironolactone usage group (pre-match: odds ratios [OR] 0.406, 95% confidence interval [CI], 0.280-0.588; post-match: OR 0.385, 95% CI, 0.259-0.571). Furthermore, post-match multivariable linear regression demonstrated a clear negative correlation between cumulative spironolactone dosage and the FRAX score. Subgroup analyses consistently supported these findings. Conclusion: This study offers evidence supporting the significant positive impact of the antihypertensive drug spironolactone on bone health, resulting in a substantial reduction in the risk of osteoporosis and future fractures in hypertensive patients. Future research should consider conducting large-scale, multicenter, randomized controlled trials to further investigate the long-term effects of spironolactone on bone health in hypertensive patients.

ABSTRACT

Background: Previous studies have suggested that aldosterone may play a major role in calcium-phosphorus homeostasis and bone metabolism. However, the relationship between plasma aldosterone concentrations (PAC) and bone mineral density (BMD) in middle-aged and elderly hypertensive patients remains unclear. Therefore, this study sought to investigate the relationship between PAC levels and BMD and explore PAC's potential impact on osteoporosis and future fracture risk in hypertensive patients. Methods: Our study included a total of 1430 participants. Associations are tested using multiple linear and logistic regression models. Nonlinearity was investigated using the restricted cubic spline (RCS). We also performed mediating analyses to assess mediating factors mediating the relationship between PAC and osteoporosis. Results: The multiple linear regression showed a negative correlation between PAC and BMD and was generally positively associated with FRAX scores. Meanwhile, logistic regression analyses indicated that osteoporosis was highly correlated with PAC levels. In addition, a clear non-linear dose-response relationship was also shown in the constructed RCS model. Finally, mediation analyses showed that serum potassium played an important role in the development of osteoporosis. Conclusion: This study demonstrates that elevated PAC levels are strongly associated with decreased BMD, increased prevalence of osteoporosis, and the risk of future fractures in middle-aged and elderly hypertensive patients. Further studies are needed to confirm this relationship and reveal its underlying mechanisms.

ABSTRACT

PURPOSE: Osteoporosis is a pressing public health concern among older adults, contributing to substantial mortality and morbidity rates. Low- to middle-income countries (LMICs) often grapple with limited access to dual-energy X-ray absorptiometry (DXA), the gold standard for early osteoporosis detection. This study aims to assess the performance of the FRAX® score as a population-wide screening tool for predicting osteoporosis risk, rather than fracture, in individuals aged 50 and above within an LMIC context. METHODS: This retrospective cohort study (n=864) assessed the performance of the FRAX® score for predicting osteoporosis risk using comparative c-statistics from Receiver Operating Characteristic (ROC) curves. Hazard ratios (HR) and 95 % confidence intervals (CI) were calculated, with p-values <0.05 indicating statistically significant. RESULTS: The 10-year FRAX® probability for hip fracture, calculated without bone mass density (BMD), exhibited significantly superior performance compared to the 10-year FRAX® probability for major fracture in predicting osteoporosis risk (AUROC: 0.71 versus 0.67, p<0.001). Within 2 to 10 years of follow-up, the 10-year FRAX® probability for hip fracture showed both greater predictive performance and net benefit in the decision curve compared to the FRAX® 10-year probability for major fracture. A newly established cutoff of 1.9 % yielded a negative predictive value of 92.9 % (95 %CI: 90.4-94.8 %) for the 10-year FRAX® probability for hip fracture. CONCLUSION: The 10-year FRAX® probability for hip fracture estimated without BMD emerges as an effective 10-year screening tool for identifying osteoporosis risk in aged 50 and older, especially when confronted with limited access to DXA scans in LMICs. MINI ABSTRACT: The Fracture Risk Assessment Tool score performance as an osteoporosis screening tool was assessed in areas with limited dual-energy X-ray access. The hip fracture probability showed better performance than major fracture probability within 2 to 10 years. The tool emerges as effective for screening osteoporosis risk in individuals over 50.

ABSTRACT

AIM: The purpose of this study was to investigate the association between the metabolic score for insulin resistance (METS-IR) and bone mineral density (BMD) in American non-diabetic adults. METHODS: We conducted a cross-sectional study with 1114 non-diabetic adults from the National Health and Nutrition Examination Survey cycle (2013-2014). The associations between METS-IR and BMD of total femur and spine were assessed by the multiple linear regression and verified the non-linear relationship with a smooth curve fit and threshold effect model. Furthermore, we evaluated the relationship between METS-IR, FRAX score, and history of bone fractures. RESULTS: We found that BMD of the total femur and spine increased by 0.005 g/cm3 and 0.005 g/cm3, respectively, for a one-unit increase of METS-IR in all participants. This positive association was more pronounced among higher METS-IR participants, and there was a non-linear relationship, which was more significant when the MTTS-IRfemur was < 41.62 or the METS-IRspine was < 41.39 (ßfemur = 0.008, ßspine = 0.011, all P < 0.05). We also found that METS-IR was positively correlated with both FRAX scores in all female participants. However, METS-IR was positively correlated only with the 10-year hip fracture risk score in male participants with fractures. No significant association between METS-IR and a history of bone fractures. CONCLUSIONS: In American non-diabetic adults, there is a correlation between elevated levels of METS-IR within the lower range and increased BMD as well as decreased risk of fractures, suggesting that METS-IR holds promise as a novel biomarker for guiding osteoporosis (OP) prevention. However, it is important to carefully balance the potential benefits and risks of METS-IR in OP.

ABSTRACT

Background: Osteoporosis is characterized by a low bone mass of bone tissue. If osteoporosis is not treated properly, it will increase the high risk of fracture. The common causes of fracture on osteoporosis condition due to falls. This study aims to find the correlation between the risk of osteoporosis with fall risk (ONTARIO) based on osteoporosis fracture risk (FRAX). Methods: This study is an analytic study with a cross-sectional method. We collected the sample using random cluster sampling in the six primary health care in Malang on different times service since August-September 2021. Total patient 139, however only 132 patients were included in this study. After collecting data is complete, we analyze using Chi-square tests. Results: The mean age of participants was 63.9 ± 7.14. with the age group was dominated by the range of 60-64. It was found that the result of the FRAX SCORE had a low-risk category for major fracture osteoporosis and risk hip fracture. In contrast, from the OSTA score in this study, more than 68 participants (50.8%) were found medium and high-risk scores. Then, in ONTARIO score of the risk fall assessment, and high score in 57 participants (43.2%). If compared between OSTA and ONTARIO, there was a significant relationship between OSTA score and ONTARIO score (p < 0.000) with high-risk OSTA have a significant relationship with a high risk of falling and vice versa. Conclusion: In this study, there was a relationship between the risk of high osteoporosis and the risk of falling.

ABSTRACT

Background and Objective: Prediction of fractures in cancer survivors exposed to hormone-deprivation therapies (HDTs) is a challenge since bone loss is rapid and severe, and determinants of fractures in this setting are still largely unknown. In this study we investigated reliability of the WHO Fracture Risk Assessment Tool (FRAX) and bone mineral density (BMD) to identify subjects developing vertebral fractures during HDTs. Design: Five-hundred-twenty-seven consecutive subjects (429 females with breast cancer, 98 males with prostate cancer; median age 61 years), under HDTs for at least 6 months, were evaluated for vertebral fractures by a radiological and morphometric approach, in relationship with FRAX score, body mass index (BMI), BMD, age and duration of HDTs. Results: Vertebral fractures were found in 140 subjects (26.6%) and spine deformity index was significantly associated with duration of HDTs (rho 0.38; p < 0.001). Only in females, vertebral fractures were significantly associated with FRAX score for major fractures [OR 1.08; P < 0.001]. The best cut-off of FRAX score for major fractures, as calculated by receiving operating characteristic (ROC) analysis was 6.35%. In males, however, vertebral fractures were significantly and independently associated with BMI ≥ 25 Kg/m2 (OR 17.63; P < 0.001), BMD T-score below -1.0 SD at any skeletal site (OR 7.79; P < 0.001) and gonadotropin-releasing hormone agonists (GnRHa) plus abiraterone treatment (OR 11.51; P = 0.001). Conclusions: FRAX and BMD may be useful for predicting vertebral fractures in subjects undergoing HDTs, but the thresholds seem to be lower than those used in the general population. High BMI is a determinant of vertebral fractures in males under HDT.

ABSTRACT

BACKGROUND: Androgen-deprivation therapy (ADT) as a treatment modality in advanced prostate cancer has deleterious effect on bone mineral density (BMD) and quality of life (QOL). Using FRAX (Fracture Risk Assessment) model, candidates at high risk of fractures can be predicted and appropriate treatment can be initiated at early step to prevent skeletal-related events. Objectives of the present study were to evaluate bone health, implication of FRAX tool in advanced prostate cancer and to see the impact of ADT and Bone-directed therapy (BDT) on FRAX and FACT-P QOL scores. MATERIAL & METHOD: We conducted a prospective longitudinal study of 83 localized and metastatic prostate cancer patients from March 2017 to Dec 2020. FRAX tool using BMD femoral neck (GE-Lunar) was used to compute the probability of 10-year Major osteoporotic fracture (MOF) and hip fracture risk %. Patients who received monthly Zolendronic acid with or without Vitamin-D/calcium supplementation were classified as BDT group. FRAX and FACT-P were measured at baseline and 12 months follow-up and compared between different therapeutic modalities to see the impact on clinical outcomes. RESULTS: Majority of patients had skeletal metastasis (78.3%) and high-grade disease at presentation. Secondary osteoporosis was the most commonly (82.05%) observed clinical risk factor (CRF) followed by smoking (19.23%). Hip fracture risk ≥3% accounted for larger proportion of patients than did MOF risk ≥20% (21.2% and 2.5%, respectively). Statistically significant reduction was observed in both MOF and hip fracture risk in BDT group, while worsening on ADT. ADT duration correlated positively with both MOF and hip fracture risk (R2=0.148, P<0.001 and R2=0.164, P<0.001, respectively). FRAX score accurately predict future fracture events in majority (80%) of high-risk patients. Statistically and clinically significant worsening in PWB, EWB, PCS, FACT-P Total, FACT-P TOI and FAPSI scores were observed in patients on ADT. Statistically and clinically significant improvement was noted in physical well-being in BDT group. However, other QOL domains and FACT-P total scores remained stable. CONCLUSIONS: ADT caused duration depended worsening of FRAX and FACT-P score in these patients while improvements of FRAX were seen on BDT. FRAX tool is advantageous in identifying the patients who require early intervention or therapy to decrease skeletal-related events.

ABSTRACT

PURPOSE: Previous reports have identified the important role of zinc in bone health. Although the risk of zinc deficiency is still a concern in the U.S., there has never been an in-depth study of the association between zinc status and bone health in a sample representing the country. METHODS: We included 2,895 subjects (aged ≥ 40 years) from National Health and Nutrition Examination Survey (NHANES) 2013-2014 to explore the relationship among three biomarkers of zinc (serum, food, and total intake), the bone mineral density (BMD) of the total spine and femur, the FRAX® scores, and the previous history of bone fractures. RESULTS: We showed a one-unit increase in the ln-serum zinc level was associated with an increase in the total spine BMD (ß = 0.068; S.E. = 0.028; P = 0.030) and total femur BMD (ß = 0.061; S.E. = 0.017; P = 0.003), while a one-unit increase in the ln-food zinc intake amount was correlated with an increase in the total femur BMD in the participants (ß = 0.023; S.E. = 0.009; P = 0.021). The ln-total zinc intake amount was correlated with an increase in the total femur BMD in women (ß = 0.016; S.E. = 0.007; P = 0.041). We also found food zinc intake was negatively correlated with the FRAX® score, while increased levels of all three zinc biomarkers were associated with a decreased incidence of previous bone fractures. CONCLUSIONS: In this representative survey of American adults above 40 years old, higher zinc status was associated with higher total spine and femoral BMD, lower FRAX® scores, and lower incidence of previous fractures. If this finding is causal, increased zinc intake remains an important issue for Americans.

ABSTRACT

Glucocorticoid-induced osteoporosis (GIOP) is a frequently encountered and serious side effect of glucocorticoid use. Bone loss leading to an increased risk for fracture occurs early in the use of glucocorticoids, yet patients at risk for this complication are often undertreated. All physicians prescribing glucocorticoids should therefore be familiar with a basic approach to anticipating and preventing GIOP when starting patients on glucocorticoid therapy. This manuscript and its case vignettes are designed to help dermatologists assess and manage bone health to prevent GIOP in patients receiving glucocorticoid therapy.

ABSTRACT

Celiac disease is associated with an increased fracture risk but is not a direct input to the FRAX® calculation. When celiac disease is considered as a secondary osteoporosis risk factor or BMD is included in the FRAX assessment, FRAX accurately predicts fracture risk. INTRODUCTION: The fracture risk assessment tool (FRAX®) uses clinical factors and bone mineral density (BMD) measurement to predict 10-year major osteoporotic (MOF) fracture probability. The study aim was to determine whether celiac disease affects MOF risk independent of FRAX score. METHODS: The Manitoba BMD Registry includes clinical data, BMD measurements, 10-year probability of MOF calculated for each individual using the Canadian FRAX tool and diagnosed celiac disease. Using linkage to population-based healthcare databases, we identified incident MOF diagnoses over the next 10 years for celiac disease and general population cohorts. RESULTS: Celiac disease (N = 693) was associated with increased fracture risk adjusted for FRAX score computed without secondary osteoporosis or BMD (adjusted hazard ratio [HR] 1.43, 95% confidence interval [CI] 1.11-1.86). Celiac disease was no longer a significant risk factor for fracture when secondary osteoporosis or BMD were included in the FRAX calculation (p > 0.1). In subjects with celiac disease, each SD increase in FRAX score (calculated with and without secondary osteoporosis or BMD) was associated with higher risk of incident MOF (adjusted HR 1.66 to 1.80), similar to the general population (p-interaction > 0.2). Including celiac disease as secondary osteoporosis or including BMD in FRAX 10-year MOF probability calculations (10.1% and 8.6% respectively) approximated the observed cumulative 10-year MOF probability (10.8%, 95% CI 7.8-13.9%). CONCLUSIONS: Celiac disease is associated with an increased risk of major osteoporotic fractures. When celiac disease is considered as a secondary osteoporosis risk factor or BMD is included in FRAX assessment, FRAX accurately predicts fracture risk.

ABSTRACT

Selenium is an essential trace mineral element for humans. Although previous in vitro and animal studies have reported the vital role of selenium in bone, the results of the relationship between the selenium status and bone health were inconsistent in epidemiological studies. The risk of selenium deficiency is negligible for U.S. general population, however, the relationship between selenium status and bone health has never been surveyed in a nationally representative sample. In this study, we analyzed the data of 2983 adults (aged ≥40 years) in the National Health and Nutrition Examination Survey (NHANES) 2013-2014 to investigate the association among three markers of the selenium status (measured from whole blood, serum, and dietary intake), total spine and femur bone mineral density (BMD), and FRAX scores, and history of bone fractures. We found a one-unit increase in the ln-whole-blood selenium level was correlated with an increase in the total femur BMD of 0.064 g/cm2 (S.E. = 0.025; P = 0.022) in all participants and 0.086 g/cm2 (S.E. = 0.031; P = 0.013) in menopausal women. Additionally, a one-unit increase in the ln-selenium intake amount was associated with an increase in the total femur BMD of 0.014 g/cm2 (S.E. = 0.007; P = 0.043) in all participants. We also found that the dietary and whole-blood selenium statuses were negatively associated with the FRAX score, while levels of all the three selenium biomarkers were negatively associated with a history of bone fractures. In conclusion, increased selenium status is correlated with an increased total femur BMD, decreased FRAX scores, and a reduced incidence of previous bone fractures in the U.S. representative survey of adults. Further study is warranted to clarify the causal inference.

ABSTRACT

OBJECTIVE: Controversy exists about the impact of bone mineral density (BMD) and fracture risk in newly diagnosed patients with breast cancer (BC). It is presumed that there are differences in BMD between women with BC and healthy controls. BMD is therefore considered as a potential marker to predict BC risk. This study was conducted to investigate the association of BMD, trabecular bone score (TBS) and fracture risk in younger postmenopausal women with hormone responsive BC. METHODS: Overall, 343 women were examined. Women with BC were matched to a control group of the general population. Forty-nine women and fifty-nine controls were included in the final analysis. All subjects underwent dual energy x-ray absorptiometry (DXA) of the lumbar spine, femoral neck, and the total hip to evaluate bone mineral density. The 10-year fracture risk for a major osteoporotic fracture was assessed using the FRAX-score and the TBS-adjusted FRAX-Score, respectively. RESULTS: Lumbar and femoral neck BMD were similar in BC patients and controls. No difference was found for TBS of the spine (1.38 ± 0.1 vs.1.36 ± 0.09) in the BC and the control group, respectively (p = 0.19). The 10- year probability for a major osteoporotic fracture (MoF) or femoral neck (FN) fracture was 6.1 (± 2.6%) and 0.9 (± 1.2%) in the BC group vs. 6.7 (± 3.5%) (p = 0.33) and 0.9 (± 1.1%) (p = 0.73) in the control group. CONCLUSION: Postmenopausal women younger than 60 years with breast cancer do not show any differences in baseline BMD, TBS, or TBS adjusted FRAX in comparison to controls.

ABSTRACT

Objectives: To assess the change in the bone mineral density (BMD) score, bone-specific biomarkers (serum vitamin D3, tartrate-resistant acid phosphatase 5b [TRAP-5b], and osteocalcin), quality of life, Ayurvedic symptoms (Asthikshaya Lakshanas), and fracture risk assessment tool (FRAX) scores following treatment with Panchatikta Ghrita (PG), a classical herbal formulation as add-on therapy to calcium and vitamin D3 supplements. Study design: Randomized, open-labeled, comparative, controlled clinical study. Location: TN Medical College and BYL Nair Hospital, Mumbai, India. Study participants: Eighty adult patients, aged between 40 and 75 years, diagnosed to have osteopenia (BMD T-score between -1 and -2.5 in at least two of the three joints tested-lumbar spine L1-L4, left femur-neck, left forearm-radius total). Study intervention: Treatment group received two tablespoons of PG (10 mL in lukewarm milk) along with calcium and vitamin D3 supplements twice a day, whereas control group received only calcium and vitamin D3 supplements twice a day for a period of 12 months. Outcome measures: BMD, bone-specific biomarkers (vitamin D3, TRAP-5b, and osteocalcin), quality of life, Ayurvedic symptoms, and FRAX scores were evaluated before and at 6 and 12 months. Results: Eighty patients were enrolled; of which, 65 patients completed the study while 15 patients dropped out. Improvement in the BMD scores was observed at 6 and 12 months with the maximum benefit in the lumbar spine region. Significant improvement in the bone-specific biomarkers, namely serum vitamin D3 (p < 0.001), osteocalcin (p < 0.001), and TRAP-5b (p < 0.05), was observed in the PG-treated group compared with the standard treatment group. Improvement in the quality of life, Ayurvedic symptoms scores, and risk reduction in FRAX scores of major osteoporotic fracture risk and hip fracture risk was greater with PG, although not statistically significant. Conclusions: The study findings demonstrate that PG slows down the bone degeneration processes by its stabilizing effect on the bone-specific biomarkers, indicating its potential usefulness as preventive therapy in osteopenia. The positive improvement noted in this study needs to be confirmed in studies with a larger sample size and longer duration.

ABSTRACT

PURPOSE: Early low bone mass is a risk factor for osteoporotic fractures associated with multiple factors, including menopause and chronic liver diseases. Hepatitis C virus (HCV) also plays a major role in chronic liver disease and has many extrahepatic consequences, such as decreased bone mineral density (BMD). This study aimed to examine the hypothesis that HCV seropositivity is independently associated with menopausal BMD loss. METHODS: This community-based, cross-sectional study was based in two rural townships in Yunlin County, Taiwan. A total of 636 menopausal women aged 45-80 years who underwent annual health checks were included. Viral markers of HCV, dual-energy X-ray absorptiometry and fracture risk assessment tool (FRAX) scores were measured. Logistic regression analysis was performed to assess the association between various predictors and the presence of low BMD. RESULTS: The participants (median age: 65 years) had a HCV seropositivity rate of 32.2%. BMD was significantly lower in the HCV-seropositive participants in different anatomic locations than in the seronegative individuals (lumbar spine: -1.5 vs -1.1; total hip: -0.9 vs -0.6; femoral neck: -1.2 vs -1.0; p<0.05). HCV-seropositive subjects had higher rates of major osteoporotic fractures (11.3%±7.6%vs 9.0±6.8%; p<0.001) and hip fractures (3.4%±4.7%vs 2.3±4.9%; p=0.006) and a higher risk of lower BMD (osteopenia and osteoporosis) based on a multivariable regression analysis (adjusted OR: 1.8; 95% CI 1.16 to 2.81; p=0.009). CONCLUSIONS: HCV infection may be an independent risk factor for menopausal BMD loss and fractures predicted by FRAX.

ABSTRACT

There was no significant difference between the areas under receiver operating characteristics (AUROCs) and diagnostic indexes (sensitivity, specificity, positive predictive value, negative predictive value) for either major osteoporotic or hip fracture FRAX scores when comparing the unadjusted and trabecular bone score (TBS)-adjusted scores. INTRODUCTION: FRAX 10-year probability of fracture can be calculated with adjustment for the TBS. Studies have shown that TBS can improve FRAX assessments in some populations. This study aimed to determine if TBS-adjusted FRAX score is better than the unadjusted score for predicting major osteoporotic fracture (MOF) and hip fracture in Australian men. METHODS: This study involved 591 men aged 40-90 years, enrolled in the Geelong Osteoporosis Study. Incident MOF (n = 50) and hip fractures (n = 14) were ascertained using radiological reports. Median follow-up time was 9.5 years (IQR7.5-11.4). Diagnostic indexes were calculated using cut points of ≥20% for MOF and ≥3% for the hip. AUROC curves were also determined for adjusted and unadjusted scores as continuous variables. RESULTS: Sensitivity was higher in the TBS-adjusted scores (MOF 4%, hip 78.6%) than the unadjusted scores (MOF 2%, hip 57.1%), with a decrease in specificity (MOF 98.9 vs 99.3%; hip 79.9 vs 83.9%). When considering TBS-adjusted and unadjusted FRAX as continuous scores, AUROCs were 0.738 and 0.740, respectively, for MOF and 0.849 and 0.848 for the hip. CONCLUSIONS: Prediction of fractures by MOF or hip FRAX was not substantially improved by TBS adjustment. There was no difference in AUROCs or diagnostic indexes for cut-off points of ≥20 for MOF and ≥3% for hip FRAX.

ABSTRACT

The Fracture Risk Assessment (FRAX) tool has been developed to estimate patients' 10-yr probability of fracture, thus establishing which patients should undergo dual-energy X-ray Absorptiometry (DXA) scan. This study aimed to evaluate if the FRAX tool can replace or optimize the use of DXA scan in celiac disease (CD). We prospectively enrolled all CD patients aged over 40 yr diagnosed at our third-level unit. At time of CD diagnosis, all patients underwent FRAX score calculation for risk of major osteoporotic and hip fractures and DXA scan (used as gold standard) to assess the accuracy of the FRAX score. The FRAX score calculation was based on the following 10 variables: age (>40 yr), sex (M/F), body mass index, history of previous fracture (yes/no), parent fractured hip (yes/no), current smoking (yes/no), use of steroids (yes/no), rheumatoid arthritis (yes/no), secondary osteoporosis (yes/no), and alcohol ≥3 units/d (yes/no). DXA assessment was performed within 1 week from FRAX calculation. The FRAX score was dichotomized as normal or pathologic in accordance with the National Osteoporosis Guideline Group. A total of 160 CD patients were enrolled (M/F = 20/140; mean age 48.7 yr). A pathologic FRAX score was evident in 14 out of 160 patients (8.7%), whereas osteoporosis based on DXA scan was found in 10 patients (6%) (κ = 0.6); 3 patients with osteoporosis (1.9%) showed a 10-yr risk of major fracture >10% according to the National Osteoporosis Guideline Group criteria. With regard to diagnostic accuracy, the FRAX score showed sensitivity of 0%, specificity of 91%, positive predictive value of 0%, and negative predictive value of 94%. The prevalence of osteoporosis in adult CD appears to be quite low and only a small proportion of patients would require a DXA investigation. The FRAX score could be an effective tool to avoid useless DXA scans in CD patients in view of its high negative predictive value.

ABSTRACT

We investigated the association between celiac disease (CD) and bone mass density (BMD) and risk of osteoporotic fractures in the general US population. In children and men ≥18 years, CD was associated with reduced BMD, and in men ≥40 years, CD was associated with increased risk of osteoporotic fractures. INTRODUCTION: Celiac disease (CD) is an autoimmune condition, characterized by inflammation of the small intestine. CD has an increasing prevalence, and if unrecognized or untreated, CD can lead to complications from malabsorption and micronutrient deficiencies. We aimed to study whether CD is an independent predictor of reduced bone mineral density (BMD) and FRAX scores in the general US population. METHODS: We used data from the National Health and Nutrition Examination Survey, 2009-2010 and 2013-2014. CD was defined by positive tissue transglutaminase IgA antibody test. Multivariable models of BMD and FRAX scores were adjusted for BMI, serum 25-hydroxyvitamin D, vitamin D and calcium supplements, milk intake, serum calcium, and smoking status, when available. RESULTS: In children, aged 8-17 years, CD was associated with decreased Z-scores, by 0.85 for hip and 0.46 for spine (both P < 0.001). In men aged ≥ 18 years, CD was associated with 0.06 g/cm2 decrease in BMD in hip and with 0.11 g/cm2 decrease in BMD in spine (P = 0.08 and P < 0.001, respectively). In women, there were no statistically significant differences in the multiple-adjusted model. In men aged ≥ 40 years, CD predicted FRAX scores, resulting in increased scores by 2.25 % (P = 0.006) for hip fracture and by 2.43 % (P = 0.05) for major osteoporotic fracture. CD did not predict FRAX scores in women aged ≥40 years. CONCLUSION: CD is independently associated with reduced BMD in children and adults aged ≥18 years and is an independent risk factor of osteoporotic fractures in men aged ≥40 years.
