Abstract
There is a strong rationale for using vitamin D in combination with anti-osteoporotic drugs. Still, available trials do not give clear indications in this setting, presenting a suboptimal and heavily inhomogeneous experimental design. Health authorities should revise requirements for using vitamin D in anti-osteoporotic drug trials to maximise their effect and produce reliable indications for clinical practice in this setting.

Radiological Factors Associated with Bisphosphonate Treatment Failure and Their Impact on Fracture Healing in Postmenopausal Women with Osteoporotic Vertebral Fractures. J Clin Med 2023; 12:jcm12113820. [PMID: 37298015 DOI: 10.3390/jcm12113820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 05/27/2023] [Accepted: 05/29/2023] [Indexed: 06/12/2023] Open
Abstract
(1) Background: Bisphosphonate treatment failure is one of the most difficult clinical problems for patients with osteoporosis. This study aimed to analyze the incidence of bisphosphonate treatment failure, associated radiological factors, and effect of fracture healing in postmenopausal women with osteoporotic vertebral fractures (OVFs). (2) Methods: A total of 300 postmenopausal patients with OVFs who were prescribed bisphosphonate were retrospectively analyzed and divided into two groups according to the treatment response: response (n = 116) and non-response (n = 184) groups. The radiological factors and the morphological patterns of OVFs were included in this study. (3) Results: The initial BMD values of the spine and femur in the non-response group were significantly lower than those in the response group (all Ps < 0.001). The initial BMD value of the spine (odd ratio = 1.962) and the fracture risk assessment tool (FRAX) hip (odd ratio = 1.32) showed statistical significance in logistic regression analysis, respectively (all Ps < 0.001). (4) Conclusions: The bisphosphonate non-responder group showed a greater decrease in BMD over time than the responder group. The initial BMD value of the spine and the FRAX hip could be considered radiological factors influencing bisphosphonate non-response in the postmenopausal patients with OVFs. The failure of bisphosphonate treatment for osteoporosis has a possible negative on the fracture healing process in OVFs.

A systematic review and meta-analysis. Int J Older People Nurs 2023; 18:e12492. [PMID: 35842938 PMCID: PMC10078370 DOI: 10.1111/opn.12492] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 06/11/2022] [Accepted: 06/13/2022] [Indexed: 01/13/2023]
Abstract
INTRODUCTION Hip fractures have a huge impact in reducing the quality of life and increasing mortality. This review aims to assess the impact of daily oral supplementation of vitamin D3 plus calcium on the incidence of hip fracture in people over 65 years. METHODS PRISMA guidelines were followed and RCTs that evaluated the effectiveness of daily oral supplementation of vitamin D3 plus calcium in preventing hip fracture in adults over 65 years were included in the study. The databases such as Cochrane Library, Embase, Medline, PubMed, CINAHL, Web of Science and Scopus were searched from October 2019- January 2020.The Cochrane risk of bias tool was used to check the quality of the included studies. A meta-analysis with fixed effect model using Review Manager (Revman 5.3) was used to analyse the data. RESULTS The meta-analysis of seven RCTs on vitamin D3 plus calcium supplementation and hip fracture (n = 12,620) identified odds ratio (OR) of 0.75; 95% Confidence interval (CI): 0.64, 0.87; p = .0003. Daily oral supplementation of 800 IU of Vitamin D3 plus 1200 mg of calcium was found more effective (n = 5676 participants; OR = 0.69; 95% CI: 0.58, 0.82; p < .0001) than daily oral supplementation of 800 IU of Vitamin D3 plus 1000 mg of calcium (n = 6555,OR = 1.08; 95% CI: 0.74, 1.56; p = .70) in reducing hip fracture. A meta-analysis of the seven RCTs to identify the incidence of non-vertebral fracture gave the OR of 0.80; 95% CI: 0.72, 0.89; p < .0001. A meta-analysis of three RCTs on femoral neck bone mineral density (BMD) (n = 483) gave a mean difference of 1.21; 95% CI: -0.79, 3.20; p = .24. CONCLUSION Daily oral supplementation 800 IU of vitamin D3 plus 1200 mg of calcium reduces hip fracture and non-vertebral fracture in older people. Administering vitamin D3 and calcium supplements had no effect in increasing the femoral neck BMD. IMPLICATIONS FOR PRACTICE Even though it is evident from the review that optimal daily intake of vitamin D3 plus calcium supplementation help in the prevention of fracture, it is only one essential element in fracture prevention. Also, people who are on dietary supplements should be compliant with same for better result. Efforts to prevent bone loss and osteoporosis should begin from an early age. It includes maintaining a healthy lifestyle, optimal intake of calcium and vitamin D3, proper nutrition, adequate exposure to sunlight, exercise etc. Proper education on healthy lifestyle, avoiding risk factors like smoking, caffeine, alcohol and awareness of bone health should continue throughout life with emphasis during menopause when increased bone loss is expected.

Abstract
Object Eldecalcitol (ED-71) is a vitamin D analog for the treatment of osteoporosis. However, inconsistent results have been reported in this regard. Hence, this meta-analysis of randomized controlled trials (RCTs) aimed to assess the efficacy and safety of ED-71 for osteoporosis. Methods The PubMed, Embase, and the Cochrane Library databases were systematically searched to identify potential trials from inception until April 2021. The investigated outcomes included bone mineral density and fractures at various sites, and potential adverse events. The pooled effect estimates were calculated using weighted mean difference (WMD) and relative risk (RR) with 95% confidence interval (CI) using the random-effects model. Results Eight RCTs involving 2368 patients were selected for the final meta-analysis. The pooled results showed that ED-71 were associated with a higher level of femoral neck (FN) bone mineral density (BMD) (WMD: 0.92; 95% CI: 0.24-1.60; P = 0.008), while it had no significant effect on lumbar spine BMD (WMD: 1.09; 95% CI: -0.11 to 2.30; P = 0.076) and hip BMD (WMD: 1.12; 95% CI: -0.16 to 2.40; P = 0.088). Moreover, the use of ED-71 could protect against the risk of all osteoporotic fracture (RR: 0.70; 95% CI: 0.55-0.88; P = 0.003) and vertebral fracture (RR: 0.74; 95% CI: 0.55-0.98; P = 0.038), while it did not affect the risk of nonvertebral fracture (RR: 0.53; 95%CI: 0.23-1.23; P = 0.140). The subgroup analyses found that the effects of ED-71 were superior to those of alfacalcidol on both BMD and fracture results. Moreover, the use of ED-71 plus bisphosphonate was associated with a greater improvement in BMD at various sites compared with bisphosphonate alone. Finally, ED-71 was associated with an increased risk of increased urine calcium level (RR: 1.69; 95% CI: 1.33-2.15; P < 0.001). Conclusion This study found that the use of ED-71 could improve BMD and fractures at various sites, especially compared with alfacalcidol or a combination with bisphosphonate for patients with osteoporosis.

Abstract
BACKGROUND Osteoporosis is a metabolic bone disease. Bisphosphonate (BP) and eldecalcitol (ELD) are two clinical first-line drugs for osteoporosis patients. However, the effect of ELD + BP vs. BP alone on osteoporosis treatment is still unclear. The present meta-analysis was conducted to evaluate the different therapeutic effect of BP + ELD vs. BP alone in osteoporosis treatment. METHODS Eligible documents that selected from online databases including PubMed, Embase, and Cochrane Library were included in this study (updated to March 3, 2020). The quality assessment of the included studies was based on the guidelines of Cochrane. Meta-analysis was performed according to criteria such as intervention plan and outcome. The indicators including bone mineral density (BMD) in all enrolled studies were included in the current analysis. Pooled odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence intervals (CI) were calculated using fixed- or random-effects models. Then, heterogeneity analysis was performed based on Cochran's Q test and I2 statistics. RESULTS A total of 4 studies (456 cases) with high quality were enrolled in this study. The effect of ELD + BP was superior to BP alone based on indicators including femoral neck BMD (FN-BMD) and total hip BMD (TH-BMD) in patients with followed up ≤ 6 months. Moreover, the effect of ELD + BP was superior to BP alone based on lumbar spine BMD (LS-BMD) in patients with 12 months followed up. CONCLUSION Therapeutic effect of ELD + BP was superior to BP alone in osteoporotic patients based on the influence of BMD.

Abstract
BACKGROUND The incidence of osteoporosis (OP) is increasing year by year. researches have shown that there was an intense link between the vitamin D (VitD) status and the efficacy of zoledronate (ZOL) in patients with osteoporosis. Since VitD is related to the geogen, its promotion effect on zoledronate has regional specificity. AIM Combining dual-energy X-ray and bone turnover markers (BTM) to explore the VitD level in postmenopausal osteoporosis patients in Harbin and monitor its effect on the anti-osteoporosis effect of ZOL. METHODS A total of 120 patients with postmenopausal osteoporosis (PMO) were enrolled .These patients were divided into two groups with 25(OH)D levels = 10ng/ml as a critical point, and each group was randomly divided into experimental groups and control groups). All of the patients were conducted 5 mg ZOL. Then the experimental group was given calcitriol and calcium carbonate, and the control group was only given calcium carbonate. BTM were measured at baseline, 24h, 3 months and 6 months. We also measured bone mineral density (BMD) of bilateral hips (TH BMD) and lumbar spine (LS BMD) at baseline and 6 months. RESULTS The VitD deficiency rates of the patients enrolled were 84.1%. There was an inverse relationship between the baseline level of VitD and the serum levels of P1NP / β-CTX, (r=-0.452,p=0.00; r=-0.225, p=0.01). Comparing with baseline, the level of serum P1NP,β-CTX in each group declined significantly after the treatment (P<0.05). The mean decreasing rates of P1NP and β-CTX in the both experimental groups were significantly higher than that of the corresponding control groups at the same time point (P<0.05), after 6 months of medication. Both TH BMD and LS BMD at 6 months increased significantly. The increase rate of LS BMD in the high VitD experimental group was significantly higher than the other three groups (P<0.05), the increase rates of TH BMD in the low VitD control group were significantly lower than the other three groups (P<0.05). CONCLUSIONS The levels of serum VitD in the patients enrolled in this study were generally low. VitD could increase the therapeutic effect of ZOL on osteoporosis.

Abstract
Factors associated with an inadequate response (IR) to bisphosphonates have been reported in many countries, but not in Japan, where the approved dose is half the global dose. We analyzed factors associated with IR to risedronate in Japanese patients with osteoporosis. This was a post hoc analysis of 1261 Japanese osteoporosis patients who received risedronate for 1 year in phase III trials. IR was defined as more than one new vertebral fracture (VF) and/or negative change in lumbar spine bone mineral density (BMD) at 1 year. Various baseline and follow-up variables were examined for potential contribution to IR. Of the 1261 subjects, 118 exhibited an IR. At baseline, IR was associated with a higher BMD, lower levels of bone turnover markers (BTM) (serum bone-specific alkaline phosphatase, urinary N-terminal telopeptide of type 1 collagen and C-terminal telopeptide of type 1 collagen), and serum 25-hydroxyvitamin D [25(OH)D] below 16 ng/mL. BTM changes were blunted at 6 months in subjects with IR. On simple regression analysis, all the above variables and poor drug adherence were associated with an IR. On multivariate regression analysis, factors associated with IR were high BMD, vitamin D deficiency at baseline and low BTM at baseline, or a decreased BTM response at 6 months. Low serum 25(OH)D and BTM as well as high BMD at baseline were independent predictors of an IR to risedronate in Japan. These results emphasize the importance of the assessment of serum 25(OH)D and BTM in the management of osteoporosis with bisphosphonates.

Abstract
This study investigated whether or not vitamin D and calcium supplementation affected bone metabolism and bone mineral density (BMD) over a period of four years of denosumab therapy in patients with primary osteoporosis. Patients were divided into a denosumab monotherapy group (22 cases) or a denosumab plus vitamin D and calcium supplementation group (combination group, 21 cases). We measured serum bone alkaline phosphatase (BAP), tartrate-resistant acid phosphatase (TRACP)-5b, urinary N-terminal telopeptide of type-I collagen (NTX), and BMD of the lumbar 1-4 vertebrae (L-BMD) and bilateral hips (H-BMD) at baseline and at 12, 24, 36, and 48 months of treatment. There were no significant differences in patient background. Serum BAP, TRACP-5b, and urinary NTX were significantly and comparably inhibited in both groups from 12 to 48 months versus baseline values. L-BMD was significantly increased at every time point in both groups, while H-BMD was significantly increased at every time point in the combination group only. There were significant differences between the groups for L-BMD at 24, 36, and 48 months (P < 0.05) and for H-BMD at 12 months (P < 0.05). Compared with denosumab monotherapy, combination therapy of denosumab plus vitamin D and calcium significantly increased H-BMD at 12 months and L-BMD from 24 to 48 months. These findings indicate that continuous vitamin D and calcium supplementation is important, especially for 12 months to improve H-BMD and from 24 to 48 months to improve L-BMD.

Abstract
To evaluate the differences in outcomes of treatment with denosumab alone or denosumab combined with vitamin D and calcium supplementation in patients with primary osteoporosis. Patients were split into a denosumab monotherapy group (18 cases) or a denosumab plus vitamin D supplementation group (combination group; 23 cases). We measured serum bone alkaline phosphatase (BAP), tartrate-resistant acid phosphatase (TRACP)-5b and urinary N-terminal telopeptide of type-I collagen (NTX) at baseline, 1 week, as well as at 1 month and 2, 4, 8 and 12 months. We also measured bone mineral density (BMD) of L1–4 lumbar vertebrae (L)-BMD and bilateral hips (H)-BMD at baseline and at 4, 8 and 12 months. There was no significant difference in patient background. TRACP-5b and urinary NTX were significantly suppressed in both groups from 1 week to 12 months (except at 12 months for NTX). In the combination group, TRACP-5b was significantly decreased compared with the denosumab monotherapy group at 2 and 4 months (P<0.05). BAP was significantly suppressed in both groups at 2–12 months. L-BMD significantly increased at 8 and 12 months (8.9%) in the combination group and at 4, 8 and 12 months (6.0%) in the denosumab monotherapy group, compared with those before treatment. H-BMD was significantly increased in the combination group (3.6%) compared with the denosumab group (1.2%) at 12 months (P<0.05). Compared with denosumab monotherapy, combination therapy of denosumab with vitamin D and calcium stopped the decrease in calcium caused by denosumab, inhibited bone metabolism to a greater extent, and increased BMD (especially at the hips).

Abstract
The aim of this 12-month retrospective study was to evaluate differences in the outcomes of denosumab alone or denosumab combined with vitamin D and calcium supplementation in patients having osteoporosis (OP) with rheumatoid arthritis (RA). Patients were divided into the denosumab monotherapy group (denosumab group, 22 cases) or denosumab plus vitamin D supplementation group (combination group, 21 cases).

We also assessed bone mineral density (BMD) of the lumbar 1-4 vertebrae (L-BMD) and bilateral total hips (H-BMD) at baseline and 4, 8, and 12 months. Matrix metalloprotanase-3 (MMP-3), Disease Activity Score-28 C-reactive protein (DAS28-CRP), Simplified Disease Activity Index (SDAI), and Health Assessment Questionnaire-Disability Index (HAQ-DI) were assessed before treatment and at 12 months to evaluate RA conditions. The study results showed that BAP, TRACP-5b, and NTX were significantly decreased, but tended to return to pre-treatment levels around 6 and 12 months in both groups. While L-BMD and H-BMD substantially increased in both groups, H-BMD had become significantly higher in the combination group at 12 months (p < 0.01) as compared with the denosumab group. There were no significant differences between the groups regarding MMP-3, DAS28-CRP, SDAI, or HAQ-DI. Compared with denosumab monotherapy, combination therapy of denosumab with vitamin D and calcium significantly increased H-BMD in patients having OP with RA.

Osteoporos Int 2017; 28:1279-1286.

Abstract
UNLABELLED We evaluated the influence of baseline age, bone mineral density (BMD), and serum levels of vitamin D on the response to risedronate treatment. Risedronate consistently increased BMD, but our results suggest vitamin D supplementation may be necessary to achieve optimal treatment effect. Furthermore, early intervention may help prevent bone fractures. INTRODUCTION We aimed to investigate the influence of baseline age, BMD, and vitamin D insufficiency on the response to risedronate treatment. METHODS Data regarding 1447 patients was obtained from the registries of three phase III clinical trials of risedronate. The response to treatment was expressed in terms of BMD increase and occurrence of new vertebral fractures. The patients were stratified by baseline values for age (<65, 65-72, and ≥72 years), lumbar spine BMD T-score (osteoporotic, <-2.5; and non-osteoporotic, ≥- 2.5), and serum levels of 25-hydroxyvitamin D (deficient, <21 ng/mL; and non-deficient, ≥21 ng/mL). RESULTS Risedronate consistently increased lumbar spine BMD in all the groups, with similar percentage and absolute increments in all the age tertiles. The percentage, but not absolute, increment in BMD was significantly higher (p = 0.0003) in the osteoporotic than that in the non-osteoporotic patients (baseline). Of the 1330 patients whose baseline serum levels of 25-hydroxyvitamin D were available, 44.7% had vitamin D deficiency (<20 ng/mL), while 89.2% had insufficiency (<30 ng/mL). The percentage and absolute increments in BMD were lower (p < 0.05 and p < 0.01, respectively) in the vitamin D-deficient than those in the non-deficient patients. New vertebral fractures occurred in 1.5 and 0.8% of the osteoporotic and non-osteoporotic patients, respectively (end of the treatment). CONCLUSIONS Therapeutic response in elderly patients is consistent, but early initiation of risedronate treatment may help prevent fractures. Risedronate-induced increase in BMD is lower in patients with vitamin D deficiency, suggesting that vitamin D supplementation is important to achieve optimal treatment response.

Clin Ther 2016; 38:1686-1695.e3.

Abstract
PURPOSE Fragility fractures are a clinical consequence of osteoporosis (OP). Evidence suggests however, current OP treatments may be inadequate in reducing fracture risk. The purpose of this study was to estimate the proportion and characteristics of Swedish patients who remain at high risk of fracture after 2 years of treatment, as evidenced by osteoporotic bone mineral density (BMD), a decrease in BMD, or the occurrence of new fractures. METHODS This was a retrospective, descriptive analysis of a subset of participants obtained from a Swedish osteoporosis patient registry from 1991 to 2009. Patients were required to be osteoporotic, to be treatment naive at baseline, to have returned for at least 1 follow-up visit, and to have reported osteoporosis treatment use for ≥2 years after the baseline visit with a BMD T score. Two overlapping cohorts remaining at high risk of fracture were defined using the BMD T score measured after 2 years of treatment from baseline. The osteoporosis cohort comprised patients who remained osteoporotic, whereas the BMD decrease cohort included patients whose total hip or lumbar spine T score decreased by ≥3%. FINDINGS A total of 3292 osteoporotic patients were identified in the registry, of whom 392 met the study inclusion criteria. The mean (SD) patient age was 68.3 (8.5) years, with most patients being female (92.3%). Among all patients, 297 (75.8%) remained osteoporotic after at least 2 years of treatment, 90 (23.0%) experienced a BMD decrease of ≥3%, and 23 (5.9%) reported an incident fracture between the baseline and first follow-up visit. More than three-quarters (76.8%) of all patients reported taking bisphosphonates, whereas only 72.4% and 47.8% reported this in the osteoporosis and BMD decrease cohorts, respectively. Raloxifene was the only nonbisphosphonate used, with 24.2% of all patients reportedly taking it. IMPLICATIONS This study highlighted that despite 2 years of osteoporosis treatment, a high percentage of patients remain at high risk of fracture. There is a need for improved treatment strategies that reduce fracture risk and improve patient outcomes in the real-world setting.

J Bone Miner Metab 2016; 34:243-50.

Abstract
The aim of this observational, nonrandomized study was to compare the effects of 12 months of monthly minodronate (MIN; 50 mg/month) monotherapy and MIN combination therapy with vitamin K2 (VK; 45 mg/day) or eldecalcitol (ELD; 0.75 μg/day) in treatment-naïve patients with primary osteoporosis. Patients (n = 193; 178 postmenopausal women and 15 men; mean age 71.6 years) were treated with (1) MIN monotherapy (n = 63), (2) MIN plus VK combination therapy (n = 50), or (3) MIN plus ELD combination therapy (n = 80) for 12 months. Changes in bone mineral density (BMD) and the levels of serum bone turnover markers were monitored. No significant difference was observed in baseline BMD among the three groups. After 12 months, BMD increased by 2.93, 4.65, and 6.55 % in the lumbar spine, 0.66, 2.57, and 3.42 % in the total hip, and 0.05, 2.06, and 3.58 % in the femoral neck in groups 1, 2, and 3, respectively. The BMD increase induced by MIN plus ELD combination therapy was significantly greater than that induced by MIN monotherapy in the lumbar spine (P = 0.0002), total hip (P = 0.003), and femoral neck (P = 0.004), and also that induced by MIN plus VK combination therapy in the lumbar spine (P = 0.03). MIN plus ELD combination therapy compared with MIN monotherapy resulted in a greater decrease in serum procollagen type I N-terminal propeptide levels (-37.4 % vs -54.6 %; P = 0.001) and tartrate-resistant acid phosphatase isoform 5b levels (-41.1 % vs -52.9 %; P = 0.009) at 3 months, and a greater decrease in procollagen type I N-terminal propeptide levels (-64.3 % vs -50.3 %; P = 0.03) and a decrease in intact parathyroid hormone levels (-12.3 % vs 14.0 %; P = 0.01) at 12 months. Combination therapy with MIN and VK or ELD for 12 months showed additive effects in decreasing the levels of bone turnover markers compared with MIN monotherapy, whereas MIN plus ELD combination therapy resulted in the highest BMD increase compared with MIN monotherapy and MIN plus VK combination therapy.

Abstract
Several previous studies have reported that bone mineral density (BMD) loss around femoral implants is a common outcome, particularly in the proximal femur, after total hip arthroplasty (THA). The purpose of this study was to investigate the effectiveness of alendronate monotherapy and combined therapy using alendronate and alfacalcidol for BMD preservation around femoral implants after primary THA. This study series included 60 patients who were classified into monotherapy (alendronate alone) (n = 18), combined-therapy (alendronate and alfacalcidol) (n = 20) or non-medication (n = 22) groups. The periprosthetic BMD and profile of the biochemical markers such as bone-specific alkaline phosphatase and serum N-terminal telopeptides of type-1 collagen (NTX) were measured at 1, 12, 24 and 48 weeks after surgery. The BMD values in the region of the calcar of monotherapy and combined-therapy patients were maintained and were significantly higher than those of non-medication patients at each measurement period. The plasma levels of NTX in the monotherapy and combined-therapy groups were found to be significantly lower than those in the non-medication group at each measurement period. In conclusion, the monotherapy and combined-therapy regimens significantly prevent periprosthetic BMD loss around femoral implants, most notably in the calcar, compared to no medication.

Abstract
UNLABELLED Among 97 postmenopausal women with primary osteoporosis, adequate calcium and vitamin D supplementation, and good compliance to a 36-month bisphosphonate treatment, the 25.8% of patients are inadequate responders. Current smoking and a bone turnover in the upper part of the normal range increase the risk of treatment failure. INTRODUCTION To evaluate the prevalence of the bisphosphonate treatment failure and its possible associated factors in women with primary osteoporosis (PO). METHODS We studied 97 previously untreated postmenopausal women with PO and fragility fractures and/or a FRAX® 10-year probability of a major osteoporotic fracture ≥ 7.5%, before and after a 36-month treatment with alendronate or risedronate and adequate vitamin D supplementation with good compliance. At baseline and after 36 months, lumbar spine (LS) and femoral bone mineral density (BMD) were assessed by Dual X-ray absorptiometry and vertebral fractures by spinal radiographs. Spinal deformity index (SDI) was calculated. Treatment failure was defined by the presence of ≥ 2 incident fragility fractures and/or a BMD decrease greater than the least significant change. RESULTS Bisphosphonate treatment failure was observed in 25.8% of patients. Age, body mass index, years since menopause, familiar history of hip fracture, number of falls, type of bisphosphonate used, 25-hydroxyvitamin D levels (25OHVitD), BMD, SDI, and FRAX® score at baseline were not different between responders and inadequate responders. Treatment failure was associated with current smoking (OR 3.22, 95% CI 1.10-9.50, P = 0.034) and baseline alkaline phosphatase total activity levels ≥ 66.5 U/L (OR 4.22, 95% CI 1.48-12.01, P = 0.007), regardless of age, number of falls, LS BMD, and baseline SDI. CONCLUSIONS The 25.8 % of PO postmenopausal women inadequately responds to bisphosphonates, despite a good compliance to therapy and normal 25OHVitD levels. The current smoking and bone turnover in the upper part of the normal range are associated with the inadequate response to bisphosphonates.

Abstract
Bisphosphonates are pyrophosphate analogues, with a strong affinity for bones. They inhibit bone resorption and are currently the first choice of treatment for osteoporosis. Bisphosphonates should be taken in a specific manner and for at least one year to be effective in the maintenance and improvement of bone mineral density (BMD), as well as for protection against fractures. We report a case of a postmenospausal osteoporotic woman who lost BMD despite being on bisphosphonate therapy for eight years, highlighting issues that a primary care doctor needs to address before deciding on the next best option.

Abstract
Some patients sustain fractures while on antiresorptives. Whether this represents an inadequate response (IR) to treatment or a chance event has not been elucidated. We performed a study to identify which patients are more likely to fracture while on treatment. This is a multicentric, cross-sectional study of postmenopausal women on antiresorptives for osteoporosis in 12 Spanish hospitals, classified as adequate responders (ARs) if on treatment with antiresorptives for 5 years with no incident fractures or inadequate responders (IRs) if an incident fracture occurred between 1 and 5 years on treatment. Poor compliance, secondary osteoporosis, and previous anti-osteoporosis treatment other than the assessed were exclusion criteria. Clinical, demographic, analytical, dual-energy X-ray absorptiometry (DXA) variables, and proximal femur structure analysis (ImaTx™) and structural/fractal analyses of distal radius were performed. A total of 179 women (76 IRs; mean (SD): age 68.2 (9.0) years; 103 ARs, age 68.5 (7.9) years) were included. History of prior fracture (p = 0.005), two or more falls in the previous year (p = 0.032), low lumbar spine bone mineral density (BMD) (p = 0.02), 25 hydroxyvitamin D (p = 0.017), and hip ImaTx fracture load index (p = 0.004) were associated with IR. In the logistic regression models a fracture before treatment (odds ratio [OR], 3.60; 95% confidence interval [CI], 1.47-8.82; p = 0.005) and levels of 25 hydroxyvitamin D below 20 ng/mL (OR, 3.89; 95% CI, 1.55-9.77; p = 0.004) significantly increased risk for IR, while increased ImaTx fracture load (OR, 0.96; 95% CI, 0.93-0.99; p = 0.006; per every 100 units) was protective, although the latter became not significant when all three variables were fitted into the model. Therefore, we can infer that severity of the disease, with microarchitectural and structure deterioration, as shown by previous fracture and hip analysis, and low levels of 25 hydroxy vitamin D carry higher risk of inadequate response to antiresorptives. More potent regimes should be developed and adequate supplementation implemented to solve this problem.

Abstract
BACKGROUND We performed a randomized, double-blind, prospective, 16-week clinical trial to evaluate the efficacy and safety of risedronate with and without cholecalciferol on 25-hydroxyvitamin D [25(OH)D] levels and bone markers in Korean patients with osteoporosis. METHODS We randomly assigned 164 adults with osteoporosis to one of two treatment groups: weekly risedronate 35 mg and cholecalciferol 5600 IU combined in a single pill (RSD+) or weekly risedronate 35 mg alone (RSD). We measured serum levels of 25(OH)D, parathyroid hormone (PTH), and bone markers and performed muscle function tests, at baseline and after 16 weeks of treatment. RESULTS After 16 weeks of treatment, mean serum 25(OH)D increased significantly from 39·8 to 70·8 nmol/l in the RSD+ group and declined significantly from 40·5 to 35 nmol/l in the RSD group. Although both treatment groups had significant increases in serum PTH over baseline during the study, the RSD group had a significantly larger increase than the RSD+ group (13·6 vs 4·8 ng/l; P = 0·0005). In both groups, serum bone-specific alkaline phosphatase (BSAP) and C-terminal telopeptide (CTX) declined rapidly; there were no significant differences between groups. There was also no significant difference between groups in lower-extremity function tests. The overall incidence of clinical adverse events was not significantly different between groups. CONCLUSION In patients with osteoporosis, a once-weekly pill of risedronate and cholecalciferol provided equivalent antiresorptive efficacy to risedronate alone in terms of bone turnover and improved 25(OH)D level over a 16-week treatment period without significant adverse events.

Abstract
Vitamin D insufficiency and deficiency are common in the elderly. Most previous studies using alendronate have used vitamin D supplementation regardless of individual vitamin D status. However, the minimum required vitamin D levels for the efficacy of alendronate treatment of osteoporosis remain unclear. Fifty-two postmenopausal women, diagnosed with osteoporosis, were enrolled in this prospective study, in which they took 5 mg of alendronate daily for 6 months without any supplements. Associations between baseline factors and their changes during the treatment and the change in the lumbar spine bone mineral density (LS-BMD) were examined. The most appropriate cut-off level of 25-hydroxyvitamin D (25[OH]D) for the optimal increase in LS-BMD with alendronate was determined using the Akaike information criterion statistical criterion. Overall, alendronate treatment significantly increased LS-BMD by 4.7%. The basal serum 25(OH)D and change in urinary NTX were significantly associated with the increase in LS-BMD. The increase in LS-BMD between the two groups was not different when comparing those with baseline 25(OH)D above vs. below 30 ng/ml. However, 25(OH)D of 25 ng/ml was determined to be the minimum required vitamin D level for an adequate effect of alendronate. Vitamin D status may affect the increase in LS-BMD with alendronate treatment in individuals being treated for osteoporosis, and a 25(OH)D level >25 ng/ml appears to be required for an optimal LS-BMD response.

Abstract
SUMMARY This study reports on oral treatment with different doses of vitamin D3 ranging from 25 to 200 microg in females with 25-hydroxyvitamin D3 levels < 60 nmol/L screened for participation in an osteoporosis trial. A guidance to safely and efficiently achieve 25-hydroxyvitamin D3 levels > 60 nmol/L is presented. INTRODUCTION The importance of vitamin D for skeletal health has been implemented in clinical trials in osteoporosis. The threshold of 25-hydroxyvitamin D for inclusion has changed from 30 to 60 nmol/L. This study reports on oral treatment with different doses of vitamin D3 in females with 25-hydroxyvitamin D3 levels < 60 nmol/L. METHODS In 131 postmenopausal females screened for participation in an osteoporosis trial, the 25-hydroxyvitamin D3 concentration was < 60 nmol/L. They were treated with 25 (n = 22), 50 (n = 19), 75 (n = 19), 100 (n = 41) or 200 microg (n = 30) of vitamin D3 daily for at least 10 days. RESULTS In the females treated with 25, 50, 75, 100 and 200 microg of vitamin D3 daily the 25-hydroxyvitamin D3 concentrations increased significantly from 32.4 +/- 2.7 (mean +/- SEM) to 50.8 +/- 2.9, from 46.7 +/- 2.8 to 65.8 +/- 2.6, from 41.6 +/- 2.7 to 67.4 +/- 2.9, from 46.7 +/- 1.4 to 64.4 +/- 2.2 and from 42.1 +/- 2.0 to 71.2 +/- 2.8 nmol/L, respectively (p < 0.001). S-calcium increased significantly but within the reference range (p < 0.006). CONCLUSION Oral vitamin D3 safely increased 25-hydroxyvitamin D3 concentrations in all females above 60 nmol/L. This study demonstrates how to achieve the new recommended 25-hydroxyvitamin D concentrations within the screening period of a clinical trial.

Effectiveness of antiresorptives for the prevention of nonvertebral low-trauma fractures in a population-based cohort of women. Osteoporos Int 2009; 20:283-90. [PMID: 18581034 PMCID: PMC5101049 DOI: 10.1007/s00198-008-0656-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2007] [Accepted: 05/05/2008] [Indexed: 01/06/2023]
Abstract
UNLABELLED Observational studies are needed to quantify real-life effectiveness of antiresorptive therapy in the prevention of clinical fractures. Antiresorptive therapies were associated with an overall 32% reduction in low-trauma nonvertebral fracture risk among women 50 and older. Effectiveness may be lower among older women and those without risk factors. INTRODUCTION Randomized controlled trials have shown that antiresorptive therapies reduce the risk of fracture in selected populations, but further study is needed to quantify their real-life effectiveness. The study objective was to determine the association between antiresorptive use and low-trauma nonvertebral fracture in women 50 and older. METHODS The design was a retrospective nested case-control study (density-based sampling) within the Canadian Multicentre Osteoporosis Study. There were 5,979 eligible women with 453 cases and 1,304 matched controls. RESULTS The current use of antiresorptives was associated with a decreased risk of fracture with OR = 0.68, 95% CI: 0.52-0.91; where OR is the adjusted odds ratio and CI is the confidence interval. Subgroup analysis yielded OR = 0.61, 95% CI: 0.42-0.89 for ages 50-74; OR = 0.76, 95% CI: 0.50-1.17 for ages 75+; OR = 0.58, 95% CI: 0.40-0.83 for those with a major risk factor; and OR = 0.92; 95% CI: 0.59-1.42 for those without a major risk factor. Major risk factors were prevalent low-trauma fracture, vertebral deformity (grade 2+), and BMD T-score < or = -2.5. CONCLUSIONS Antiresorptive therapy is associated with a clinically important reduction in low-trauma nonvertebral fracture risk among community-dwelling women aged 50 and older. Antiresorptive therapy may be less effective for women 75 and older and women without major risk factors.

Abstract
UNLABELLED The concept of inadequate response to osteoporosis treatment is not clear. In the literature several criteria have been used. We propose an operational definition of an inadequate responder based on the changes observed in bone mineral density and incident fractures while on therapy. INTRODUCTION Fractures may occur in compliant patients even while on active treatment. These cases have been defined as inadequate responders (IR). METHODS We reviewed the basis for this concept and propose an operational definition for IR. RESULTS Good compliance and adequate calcium and vitamin D supplementation are the first requirement. The second requirement is a treatment period of at least 1 year, since before that time treatment may not have been fully effective. Fractures are the gold standard for measuring efficacy and changes in bone density and turnover markers may be surrogates. We propose classifying patient response as: Inadequate--incident fracture and a decrease in BMD greater than a significant change (Trend Assessment Margin or TAM); Possibly inadequate--incident fracture or a decrease in BMD greater than a significant change (TAM); and Appropriate--no fracture and no decrease in BMD greater than a significant change (TAM). Additional criteria (biochemical markers, bone quality parameters) may be taken into account. CONCLUSION A wide consensus on the IR concept is required given its clinical, regulatory, and reimbursement implications.

Abstract
Patients treated with pharmacological agents to improve bone strength and reduce fracture risk may not achieve optimal skeletal benefit for reasons that include poor compliance and persistence, inadequate calcium and vitamin D intake, malabsorption, and medications or co-morbidities with adverse skeletal effects. Monitoring the effects of therapy can inform the patient and physician that the drug is having its expected skeletal response. Treatment is often monitored with serial bone mineral density (BMD) measurements using dual-energy X-ray absorptiometry or bone turnover markers (BTMs). Stable or increasing BMD is associated with reduced fracture risk in clinical trials, and is considered an indication of good response to therapy in individual patients outside of clinical trials. There are many differences between subjects in clinical trials and patients being treated in clinical practice. Thus, although defining a clinical practice patient as a "nonresponder" or "suboptimal responder" to treatment is problematic, a pragmatic approach would be to consider evaluation for contributing factors and possible changes in therapy in patients who have a statistically significant decrease in BMD, do not have the expected change in BTMs, or have a fracture.

Abstract
UNLABELLED Hip fracture is associated with recurrent fractures and increased mortality. The results of our retrospective cohort study support the use of antiresorptive agents to prevent recurrent hip fractures in this population. INTRODUCTION Hip fracture, the most serious consequence of osteoporosis, is associated with recurrent fractures and increased mortality. Antiresorptive therapy has proven efficacy in the prevention of fractures after vertebral fractures. It is unknown if it can prevent recurrent fractures after a hip fracture. METHODS We designed a population based, retrospective cohort study, using administrative databases and identified patients hospitalized for a hip fracture between 1996 and 2002. The exposure was defined as being dispensed a prescription for an antiresorptive agent at any time following discharge. Multivariate Cox regression models were used to estimate the hazard ratio of recurrent hip fracture. Subgroup and propensity score analyses were performed. RESULTS A total of 20,644 patients were identified; 6,779 filled a prescription for antiresorptive agents. There were 992 recurrent hip fractures. Patients exposed to antiresorptives had a 26% reduction in the rate of recurrent fractures (adjusted hazard ratio 0.74; 95% CI, 0.64-0.86) compared to patients who were not. All subgroups experienced a reduction in recurrent fracture, except the very elderly. Propensity score analyses were consistent with the main analysis. CONCLUSIONS Antiresorptive therapy reduces the risk of recurrent hip fractures in elderly patients. These results provide evidence that this therapy should be considered for secondary prevention of hip fractures.

Abstract
INTRODUCTION Vitamin D is given to most patients with osteoporosis particularly the elderly and those on bisphosphonates. The most widely advocated dose is 800 IU with or without calcium. Whether or not this enables all or most patients to become vitamin D replete in clinical practice is not established. AIMS This study investigated a large cohort of patients with osteoporosis attending a metabolic bone clinic to identify if those on vitamin D supplements were adequately treated and if those commenced on treatment developed normal vitamin D levels. METHODS Twenty-five hydroxy vitamin D measurements from new all patients attending a district general hospital metabolic bone clinic as part of their preclinic investigations was examined. It was noted as to whether or not they were taking calcium and or vitamin D supplements. Patients not on supplements but with a low baseline vitamin D were treated with supplements and then had a repeat measurement after at least 3 months to assess whether or not they were replete. RESULTS From the database of 1028 patients, 100 had preclinic and follow-up vitamin D levels. They were of average age 61 years (SD 12) with a mean baseline vitamin D of 26 nmol/l. The mean posttreatment level was 58 nmol/l (SD 25). Posttreatment vitamin D levels were < 60 nmol/l in 55%, < 50 nmol/l in 36%, < 40 nmol/l in 24% and < 30 nmol/l in 13% and < 20 nmol/l in 4%. In 41 patients on Calcichew D3 Forte two tablets per day pretreatment vitamin D was 24 nmol/l (SD 16) and posttreatment 62 nmol/l (SD 28). Of this subgroup posttreatment 41% were < 60 nmol/l, 27% < 50 nmol/l, 22% < 40 nmol/l and 10% < 30 nmol/l. Two hundred and ten patients on vitamin D treatment preclinic had a mean vitamin D level of 64 nmol/l (SD 28). One hundred and twenty-four patients already on two tablets of Calcichew D3 Forte per day had a mean of 68 nmol/l (SD 28) of whom 38% were < 60 nmol/l, 24% < 50 nmol/l, 16% < 40 nmol/l, 6% < 30 nmol/l and 3% < 20 nmol/l. CONCLUSION Vitamin D therapy with conventional treatment improves serum levels of 25 hydroxy vitamin D but still leaves some patients with significant insufficiency and therefore the same dose of vitamin D is not appropriate for all.

Abstract
Vitamin D is a hormone that controls phosphorus, calcium, and bone metabolism and neuromuscular function. Vitamin D synthesis is a process in which the skin, liver, and kidney are sequentially involved. The vitamin D pool is completed by the amount taken with food and supplements. Vitamin D deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes a painful disease, osteomalacia, and increases muscle weakness, which worsens the risk of falls and fractures. A high prevalence of vitamin D insufficiency exists in the apparently healthy population, osteoporotic patients, and patients with prior fractures. Factors contributing to low vitamin D levels include low sunlight exposure, decreased skin synthesis and intestinal absorption, and inadequate diet. The simplest way to correct hypovitaminosis is adequate nutrition and supplements. However, few patients with osteoporosis and/or fractures, receive adequate supplements. Vitamin D insufficiency may alter the regulatory mechanisms of parathyroid hormone and may induce a secondary hyperparathyroidism that increases the risk of osteoporosis and fractures, although the necessary degree of this is not established. Monitoring of serum 25-hydroxyvitamin D levels is the only way to assess vitamin D status. The ideal healthy blood levels of 25-hydroxyvitamin D are controversial, although a range from 30 to 60ng/mL is widely accepted. The role of vitamin D supplementation is to provide humans with the nutrient in an amount closer to the biological norm for our species. This amount of vitamin D results in optimal function of many aspects of health, including balance and muscle strength, thus reducing the risk of fracture beyond what is possible via the quality and quantity of bone itself.

Abstract
Regression to the mean (RTM) is a widespread statistical phenomenon. It is a group phenomenon that occurs whenever an extreme group is selected from a population based on the measurement of a particular variable. If a second measurement is then taken for the same group, the second mean will be closer to the population mean than the first measurement. This decrease (or increase) can be mistakenly attributed to a treatment effect; the conclusion can be drawn that an effect results from treatment when it in fact results from chance. Any intervention that is aimed at a group or characteristic that is very different from the average will appear to be successful because of RTM. It is therefore important that any genuine reductions because of the treatment are separated out from the effect of RTM. If the problem is ignored then this will lead to errors in the interpretation of results and, potentially, decisions made on the evidence of those results. This paper highlights the importance of the issue and its effects on many common clinical, public health and managerial decisions.

Abstract
The goal of osteoporosis therapy is reduction of fracture risk. In randomized controlled trials, relative risk of fracture is determined by comparing the absolute fracture rate of a treatment group to a control group. Fracture risk cannot be measured in individual patients being treated for osteoporosis. Since osteoporosis is a silent disease, and some patients may not respond to therapy, a surrogate test for reduction of fracture risk is often used-most commonly a bone density test. A proposed definition of nonresponse is: A decrease in bone mineral density greater than the Least Significant Change at the 95% level of confidence. The Least Significant Change is a value based on bone density measurements in patients and calculated according to well-established standards. There are other candidates for measuring responsiveness to therapy, most notably biochemical markers of bone metabolism, but none is as well validated or standardized as bone density testing. Causes of nonresponse include poor adherence, co-morbid conditions, calcium and vitamin D deficiency, malabsorption, metabolic factors, wrong dose, wrong dosing interval, and lack of efficacy. A bone density increase or stability of bone density is associated with fracture risk reduction in approved osteoporosis therapies, while a bone density decrease is cause for clinical concern. The proposed definition of nonresponse identifies a subset of patients who may require a change of therapy and/or additional medical intervention. More data are needed to develop guidelines for clinicians. Further study is suggested.
