Abstract
OBJECTIVE To study and compare the clinical effects of Rehmannia Decoction and alendronate sodium for the treatment of primary osteoporosis. METHODS From January 2016 to December 2017, 72 patients with primary osteoporosis who took Dihuang Decoction(DHD) orally and alendronate regularly for more than one year were randomly divided into 2 groups:experimental group and control group. The experimental group consisted of 14 males and 22 females, with an average age of(63.97±3.70) years old. The patients in the experimental group took Chinese medicine DHD, one dose each time, one time in the morning and one time in the evening, twice a week. The control group consisted of 16 males and 20 females with an average age of(63.36±3.07) years old. Patients in the control group were given alendronate 70 mg orally once a week. The basic treatment for osteoporosis remained unchanged in both groups(600 mg of calcium carbonate D3 and 0.5 μg of calcitriol capsules were taken daily). Bone mineral density (BMD) of femoral neck and lumbar vertebrae was measured by dual energy X-ray absorptiometry before and after treatment for one year. The levels of serum collagen type I C-terminal peptide (beta-CTX) and serum osteoclast (SOST) were measured before and after treatment for two groups. RESULTS The age, bone mineral density, SOST and beta-CTX baseline values between the two groups before and after anti-osteoporosis treatment were compared. The difference was not statistically significant(P>0.05). Compared with the two groups, the BMD of femoral neck and lumbar vertebrae were increased after 1 year of anti-osteoporosis treatment. The differences were statistically significant (P<0.001). The value of serum beta-CTX was significantly lower than before. The t values were 52.002 and 50.071 respectively. The value of serum SOST was increased than that before treatment. The t values were -29.242 and -30.807 respectively. The differences were statistically significant (P<0.001). BMD of the femoral neck and lumbar spine was compared between the two groups after treatment. The P values were 0.294 and 0.478 respectively. The difference was not statistically significant (P>0.05). The serum beta-CTX values were compared between the two groups after treatment. The P value was 0.908. The serum SOST values were compared between the two groups after treatment. The P value was 0.888. The difference was not statistically significant (P>0.05). CONCLUSIONS In this study, traditional Chinese medicine DHD is used to treat osteoporosis. It is found that DHD and alendronate have a good effect. The DHD can be used as a choice of Chinese medicine in the treatment of primary osteoporosis.

Tan, DHS, Lee, T, Raboud, J, Qamar, A, Cheung, AM, Walmsley, S
HIV research & clinical practice. 2019;(6):140-150
Abstract
Background: Antiretroviral therapy (ART) initiation is associated with decreases in bone mineral density (BMD).Objectives: To plan for a larger trial, we sought to obtain preliminary estimates for the difference in the change in BMD at 48 weeks achieved with 24 weeks of prophylactic alendronate/vitamin D during ART initiation compared to no intervention, the within-group standard deviation of this change, and intra-patient correlation coefficient for repeated BMDs. Secondary objectives included assessing enrollment feasibility, treatment acceptability, adherence and safety.Methods: We randomized treatment-naïve HIV-positive adults initiating tenofovir disoproxil fumarate/emtricitabine/elvitegravir/cobicistat or abacavir/lamivudine/dolutegravir 1:1:1 to immediate alendronate/vitamin D3 70 mg/5600 IU for 24 weeks (concomitant treatment arm, CTA), the same intervention starting 24 weeks after study entry (delayed treatment arm, DTA), or no bone anti-resorptive therapy (standard of care, SOC). We assessed BMD, acceptability, adverse events and drug adherence at baseline, week 24 and week 48.Results: Of 29 included participants, 72% initiated TDF/FTC/ELV/c and 28% initiated ABC/3TC/DTG. Median (IQR) CD4 count was 388 (303,525) cells/mm3 and median plasma HIV RNA was 4.45 (2.26, 4.84) log10 copies/mL. The mean (SD) percentage change in BMD for the CTA and DTA combined was 1.95% (2.53%), 0.38% (3.34%), and -0.57% (3.50%) at the lumbar spine, femoral neck and total hip respectively at 48 weeks. The ICC among repeated measurements of BMD was 0.978, 0.964, and 0.967 at these sites, respectively. Enrollment feasibility, drug acceptability, adherence, and tolerability were good.Conclusions: Our findings inform the sample size for a larger trial of bone anti-resorptive therapy during ART initiation and support feasibility.

Abstract
Bisphosphonates, potent antiresorptive agents, have been found to be associated with mortality reduction. Accelerated bone loss is, in itself, an independent predictor of mortality risk, but the relationship between bisphosphonates, bone loss, and mortality is unknown. This study aimed to determine whether the association between bisphosphonates and mortality is mediated by a reduction in the rate of bone loss. Participants from the population-based Canadian Multicentre Osteoporosis Study were followed prospectively between1996 and 2011. Comorbidities and lifestyle factors were collected at baseline and bone mineral density (BMD) at baseline and at years 3 (for those aged 40 to 60 years), 5, and 10. Rate of bone loss was calculated using linear regression. Information on medication use was obtained yearly. Bisphosphonate users grouped into nitrogen bisphosphonates (nBP; alendronate or risedronate) and etidronate and non-users (NoRx) were matched by propensity score, including all baseline factors as well as time of treatment. Cox's proportional hazards models, unadjusted and adjusted for annual rate of bone loss, were used to determine the association between nBP and etidronate versus NoRx. For the treatment groups with significant mortality risk reduction, the percent of mortality reduction mediated by a reduction in the rate of bone loss was estimated using a causal mediation analysis. There were 271 pairs of nBP and matched NoRx and 327 pairs of etidronate and matched NoRx. nBP but not etidronate use was associated with significant mortality risk reduction (hazard ratios [HR] = 0.61 [95% confidence interval 0.39-0.96] and 1.35 [95% CI 0.86-2.11] for nBP and etidronate, respectively). Rapid bone loss was associated with more than 2-fold increased mortality risk compared with no loss. Mediation analysis indicated that 39% (95% CI 7%-84%) of the nBP association with mortality was related to a reduction in the rate of bone loss. This finding provides an insight into the mechanism of the relationship between nBP and survival benefit in osteoporotic patients. © 2019 American Society for Bone and Mineral Research.

Abstract
AIMS/INTRODUCTION Postmenopausal women receive bisphosphonates for osteoporosis treatment. The effect of these medications on developing diabetes mellitus in prediabetic patients is yet to be investigated. We aimed to determine the effect of alendronate on plasma glucose, insulin indices of postmenopausal women with prediabetes and osteopenia. MATERIALS AND METHODS The present triple-blind randomized controlled clinical trial included 60 postmenopausal women, aged 45-60 years. All patients were vitamin D sufficient. They were randomly enrolled in intervention (70 mg/week alendronate for 12 weeks) and control (placebo tablet per week for 12 weeks) groups. The morning 8-h fasting blood samples were collected at the baseline and follow-up visits to measure the fasting plasma glucose (mg/dL), insulin and hemoglobin A1c (HbA1c). Plasma glucose and insulin concentration were measured 30, 60 and 120 min after the glucose tolerance test. The Matsuda Index, homeostasis model assessment of insulin resistance, homeostasis model assessment of β-cell function and the area under the curves of glucose and insulin were calculated. RESULTS The mean (standard deviation) fasting plasma glucose (102.43 [1.46] mg/dL vs 94.23 [1.17] mg/dL, P = 0.001), 120-min insulin concentration (101.86 [15.70] mU/L vs 72.60 [11.36] mU/L, P = 0.026), HbA1c (5.60 [0.06]% vs 5.40 [0.05]%, P = 0.001), homeostasis model assessment of insulin resistance (3.57 [0.45] vs 2.62 [0.24], P = 0.021) and Matsuda Index (7.7 [0.41] vs 9.2 [0.4], P = 0.001) significantly improved in the alendronate-treated group. There were more statistically significant reductions in fasting plasma glucose (-8.2 [8.63] mg/dL vs -2.5 [14.26] mg/dL, P = 0.002) and HbA1c (-0.2 [0.23]% vs -0.09 [0.26]%, P = 0.015) observed in the alendronate-treated group than the placebo group during the study course, respectively. CONCLUSIONS Administration of 70 mg/week alendronate improves fasting plasma glucose, HbA1c and insulin indices in postmenopausal women.

[Sequential treatment of osteoporosis with anti-sclerostin.].
Inoue, D
Clinical calcium. 2019;(3):363-369
Abstract
Romosozumab is a humanized anti-sclerostin monoclonal antibody that has just been approved for the treatment of osteoporosis in Japan. Romosozumab causes both transient stimulation of bone formation and continuous suppression of resorption, thereby increasing bone mineral density and decreasing fracture incidence. Because the effect of romosozumab is reversible, sequential therapy with anti-resorptives after romosozumab will be necessary. This overview summarizes the results of ARCH study demonstrating superior efficacy of romosozumab compared to alendronate and effect of sequential therapy with alendronate. Possible adverse effect of romosozumab on cardiovascular diseases will also be discussed.

Abstract
OBJECTIVE To compare the efficacy differences between catgut implantation at stellate ganglion combined with oral administration of alendronate sodium and oral administration of alendronate sodium alone on postmenopausal osteoporosis (PO). METHODS Sixty patients of PO were randomly divided into an observation group and a control group, 30 cases in each one. The patients in the control group were treated with oral administration of alendronate sodium. Based on the treatment of control group, the patients in the observation group were treated with catgut implantation at stellate ganglion. The treatment was given once a week in the two groups; the consecution treatment of four weeks constituted one session, and totally six sessions were given. The changes of total syndrome score, bone mineral density of lumbar vertebra (L1 to L4) and femeral neck (FN) and estradiol were observed before and after treatment; the clinical efficacy was compared between the two groups. RESULTS Compared before treatment, the total syndrome score, bone mineral density of lumbar vertebra (L1 to L4) and FN and estradiol were significantly improved after treatment (all P<0.05); which were more significant in the observation group (all P<0.05). Compared before treatment, the level of estradiol in the control group was not significantly changed after treatment (P>0.05), while that in the observation group was significantly changed after treatment (P<0.05). After treatment, the level of estradiol in the observation group was higher than that in the control group (P<0.05). The total effective rate was 93.3% (28/30) in the observation group, which was significantly higher than 83.3% (25/30) in the control group (P<0.05). CONCLUSION Catgut implantation at stellate ganglion combined with oral administration of alendronate sodium are superior to oral administration of alendronate sodium alone for postmenopausal osteoporosis, which improve the clinical symptoms, regulate the hormone level and increase bone mineral density.

Abstract
Baseline and on-treatment characteristics, including age, obesity, calcium intake, and bone turnover markers, may predict the bone mineral density (BMD) response in women with postmenopausal osteoporosis (PMO) to 1 to 2 years of antiresorptive therapy and/or vitamin D supplementation. This study aimed to explore clinical characteristics associated with 12-month BMD improvement in Chinese women with postmenopausal osteoporosis (PMO).In this post hoc analysis of a previous phase 3 multicenter, randomized controlled trial, Chinese PMO women who were treated with once weekly alendronate 70 mg/vitamin D3 5600 IU (ALN/D5600) or once daily calcitriol 0.25 mcg, and had measurements of 1-year lumbar spine BMD (LS-BMD) and on-treatment bone turnover markers (BTMs) were included in the analysis.In Chinese PMO patients on ALN/D5600, 1-year LS-BMD change was negatively correlated with age (β = -0.00084, P < .01), dietary calcium (β = -0.0017, P = .07), and procollagen type 1 N-terminal propeptide (P1NP) change at month 6 (β = -0.000469, P = .0016), but positively with body mass index (BMI) (β = 0.00128, P = .08); baseline P1NP above the median was associated with a significantly greater BMD percentage change at the lumbar spine (P = .02) and the total hip (P = .0001). In the calcitriol group, a significant 1-year LS-BMD increase was associated with BMI (β = 0.0023, P = .02), baseline P1NP (β = 0.00035, P = .0067), history of prior vertebral fracture(s) (β = 0.034, P < .0001) and baseline serum 25(OH)D level (β = -0.00083, P = .02).The presented findings from Chinese postmenopausal osteoporotic women suggested clinically meaningful baseline and on-treatment characteristics predicting BMD improvement after 1 year of ALN/D5600 treatment, which differed from calcitriol treatment with baseline identifiable associations. The study remained exploratory and further accumulation of evidence is needed.

Abstract
BACKGROUND It is generally believed that Thai people do not suffer from hypovitaminosis D because there is abundant sunlight throughout the year, and that taking vitamin D supplements could result in abnormally high levels of vitamin D. This is a Thai FDA-driven study to investigate this risk over a period of 26 weeks of taking alendronate sodium/vitamin D3 combination tablets. METHODS Osteoporosis patients in Thailand were recruited to a multicenter, open-label, 6-month trial of oral alendronate sodium 70 mg/vitamin D3 5600 IU. Patients received study medication once a week for 26 weeks. Serum 25-hydroxyvitamin D (25(OH)D) and Beta-CrossLaps (β-CTx) levels were measured at baseline and 26 weeks. The primary endpoint was the proportion of patients with 25(OH)D ≥ 50 ng/mL at week 26; it was hypothesized that 26 weeks' treatment would not result in 25(OH)D serum levels ≥ 50 ng/mL in > 7% of osteoporosis patients. RESULTS One hundred ninety-eight patients were recruited. At baseline, 67.2% of the patients had 25(OH)D < 30 ng/mL; this declined to 34.4% by week 26. The mean 25(OH)D level improved from 27.8 ng/mL at baseline to 33.6 ng/mL at week 26. Five patients (2.69% of the full analysis set) had 25(OH)D levels ≥ 50 ng/mL at 26 weeks. The highest 25(OH)D level, 64.3 ng/mL, was observed in a patient whose baseline level was 102.2 ng/mL. The majority (62.9%) of the patients had optimal 25(OH)D levels (30-50 ng/mL). β-CTx levels were reduced by 57.7% after 26 weeks' treatment. No clinically significant cases of hypercalcemia which could be associated with hypervitaminosis D were identified during physical examination, in vital signs, or in laboratory results. Overall, 73 patients (36.9%) reported at least one adverse event (AE), with 13 (6.6%) reporting drug-related AEs. Four patients discontinued due to AEs, two of which were drug-related. Serious AEs were reported for four patients, of which one was considered drug-related. CONCLUSIONS Oral alendronate sodium 70 mg plus vitamin D3 5600 IU once weekly had an acceptable safety profile in this study, and increased serum 25(OH)D and reduced β-CTx levels in osteoporosis patients. This treatment improved 25(OH)D levels, without causing abnormally high levels, after 26 weeks' treatment. TRIAL REGISTRATION Clinical Trials.gov NCT01437111 , Registered September 19, 2011.

Abstract
The aim of this study was to assess changes in bone mineral density (BMD) and cadmium (Cd) levels in blood and urine in individuals living in a Cd-contaminated area according to the type of osteoporosis medication over a three-year period. This follow-up study included 204 residents living in the vicinity of a closed copper refinery, who had been found to have elevated urinary or blood Cd levels. Cd levels in the blood and urine, as well as BMD, were measured every 6 months. After the first BMD measurement, individuals were prescribed antiresorptives such as alendronate or vitamin D and calcium, according to their BMD. Subjects were classified according to the type of medicine provided over the previous 6 months. General linear models controlling for other factors were used to evaluate the effects of each type of medication on the participants' Cd levels and BMD. Spinal BMD showed a significant increase in the antiresorptive group compared to the nontreatment group. Significant decreases in blood Cd levels were found in the vitamin D and calcium group, in comparison to the nontreatment group, as well as a marginally significant decrease in the antiresorptive group. The vitamin D and calcium group showed a significantly greater decrease in urinary Cd levels than the nontreatment group. In contrast, antiresorptive medication was found to have a negative effect on urinary Cd excretion. These results suggest that vitamin D and calcium treatment for osteoporosis lowers blood Cd levels more effectively and improves urinary Cd excretion.

Archives of endocrinology and metabolism. 2018;(4):438-445
Abstract
OBJECTIVE This study evaluated the effects of combination therapy of curcumin and alendronate on BMD and bone turnover markers in postmenopausal women with osteoporosis. SUBJECTS AND METHODS In a randomized, double-blind trial study, 60 postmenopausal women were divided into three groups: control, alendronate, and alendronate + curcumin. Each group included 20 patients. Total body, total hip, lumbar spine and femoral neck BMDs were measured by dual-energy X-ray absorptiometry (DXA) at baseline and after 12 months of therapy. Bone turnover markers such as bone-specific alkaline phosphatase (BALP), osteocalcin and C-terminal cross-linking telopeptide of type I collagen (CTx) were measured at the outset and 6 months later. RESULTS Patients in the control group suffered a significant decrease in BMD and increased bone turnover markers at the end of study. The group treated with only alendronate showed significantly decreased levels of BALP and CTx and increased levels of osteocalcin compared to the control group. The alendronate group also showed significant increases in the total body, total hip, lumbar spine and femoral neck BMDs at the end of study compared to the control group. In the curcumin + alendronate group, BALP and CTx levels decreased and osteocalcin levels increased significantly at the end of study compared to the control and alendronate groups. BMD indexes also increased in four areas significantly at the end of study compared to the control and alendronate groups. CONCLUSION The combination of curcumin and alendronate has beneficial effects on BMD and bone turnover markers among postmenopausal women with osteoporosis. Arch Endocrinol Metab. 2018;62(4):438-45.
