The Efficacy and Safety of Chinese Herbal Medicine Xianling Gubao Capsule Combined With Alendronate in the Treatment of Primary Osteoporosis: A Systematic Review and Meta-Analysis of 20 Randomized Controlled Trials

Role of traditional Chinese medicine on fracture, hospitalization, and total mortality risks in patients with hyperthyroidism and osteoporosis

Previous studies have confirmed that hyperthyroidism is one of the common causes of secondary osteoporosis and can aggravate the disease severity in patients with osteoporosis. This study is mainly based on the Taiwan National Health Insurance Database and through big data analysis shows that combining traditional Chinese medicine (TCM) treatment can help the health of patients with hyperthyroidism and osteoporosis. There were 4980 patients who received TCM treatment and 19,920 controls who did not receive TCM treatment selected from Taiwan National Health Insurance Database in a 4:1 ratio of gender, age, and index year. Cox proportional hazards analyzes were performed to compare fracture, inpatient, and all-cause mortality over an average follow-up period of 15 years. A total of 4745/5823/3487 enrolled subjects (19.06%/23.39%/14.00%) suffered fractures/hospitalization/all-cause death which TCM group was 452/987/511 (15.10%/19.82%/10.26%); control group was 3993/4836/2976 (20.05%/24.28%/14.94%). Cox proportional hazards regression analysis showed that subjects in the TCM group had lower fractures, hospital mortality, and all-cause mortality (adjusted HR = 0.563; 95% confidence intervals [CI] = 0.392-0.680, P < .001; adjusted HR = 0.614; 95% CI = 0.474-0.714, P < .001; adjusted HR = 0.691; 95% CI = 0.569-0.792, P < .001). Kaplan-Meier analysis showed that the cumulative risk of fracture, hospitalization and death were lower in TCM group with significant differences (all log-rank P < .001). The analysis of this study shows that patients with hyperthyroidism and osteoporosis even with comorbidity of atrial fibrillation, atrial flutter, or heart failure combined with TCM treatment are associated with a lower risk of fractures, hospitalization, or all-cause death, providing clinicians with a treatment option.

Additional effects of herbal medicine combined with bisphosphonates for primary osteoporosis: a systematic review and meta-analysis

Background

Osteoporosis (OP) is a significant medical issue associated with population aging. Recent research on herbal medicines (HMs) for OP has been increasing, with these therapies sometimes used in conjunction with bisphosphonates (BPs), the standard treatment for OP. We conducted a systematic review and meta-analysis to evaluate the effects of combining HMs with BPs on improving bone mineral density (BMD) in patients with primary OP.

Methods

We searched nine databases-PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure Wanfang, KISS, Kmbase, Science On, and Oasis-up to 31 August 2023. We selected randomized controlled trials (RCTs) comparing BMD between HMs plus BPs and BPs alone in primary OP. A meta-analysis with BMD as the primary outcome was performed using RevMan version 5.4. Study quality and evidence certainty were assessed through Cochrane's risk of bias2 and GRADE.

Results

Out of 43 RCTs involving 4,470 participants (mean age 65.8 ± 6.6 years), 35 RCTs with 3,693 participants were included in the meta-analysis. The combination of HMs and BPs was found to be more effective in improving BMD compared to BPs alone, with improvements of 0.10 g/cm2 at the lumbar spine (33 RCTs, 95% CI: 0.07-0.12, p < 0.001, I2 = 93%) and 0.08 g/cm2 at the femoral neck (20 RCTs, 95% CI: 0.05-0.12, p < 0.001, I2 = 94%), though this result was associated with high heterogeneity, high risk of bias, and very low certainty of evidence.

Conclusion

Our data suggest the possibility that combining HMs with BPs may improve BMD in primary OP more effectively than using BPs alone. However, the results should be interpreted with caution due to the high heterogeneity and low quality of the studies included in the review. Therefore, further well-designed RCTs are needed to confirm these findings.

Efficacy of Xianling Gubao capsule vs. its combination therapy in the treatment of primary osteoporosis: A network meta-analysis of randomized controlled trials

Objective

This study aimed to evaluate the efficacy of the Xianling Gubao (XLGB) capsule alone and its combination therapy in primary osteoporosis (POP).

Methods

Databases including PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP, and SinoMed were searched from their inception to January 16, 2024, for randomized controlled trials (RCTs) investigating the XLGB treatment for POP. A network meta-analysis (NMA) was performed to evaluate the efficacy and safety of multiple interventions in the treatment of POP. The Cochrane risk-of-bias tool was used to assess the quality of RCTs included in the meta-analysis. Software Stata (version 15.0) was used for statistical analysis. The surface under the cumulative ranking curve (SUCRA) method was used to present the findings from this NMA numerically and graphically by ranking multiple interventions.

Results

A total of 107 RCTs were included in the meta-analysis, involving 10,032 participants and 21 interventions. Meta-analysis showed that XLGB + calcium (Ca) + calcitonin (99.9 %) was the most desirable treatment option for improving clinical efficacy. XLGB + Ca + bisphosphonate (BP) was most effective for improving bone mineral density (BMD) at the lumbar spine, femoral neck BMD, and serum bone Gla protein (BGP). SUCRA values for improving these three outcome measures by XLGB + Ca + BP were 87.4 %, 77.2 %, and 84.3 %, respectively. XLGB + calcitonin was the optimal option in terms of safety evaluation and improving visual analogue scale (VAS), with the SUCRA values being 89.6 % and 94.9 %, respectively.

Conclusions

The XLGB combination therapy is a desirable option for treating POP as it can effectively improve the therapeutic effects, BMD, and serum BGP, as well as relieve pain in patients with POP.

Impact of postmenopausal osteoporosis on the lives of Omani women and the use of cultural and religious practises to relieve pain: A hermeneutic phenomenological study

INTRODUCTION

Osteoporosis is a significant clinical and public health concern worldwide. Despite the impact of this condition on women's lives, most studies have focused on its clinical manifestations, drug efficacy, and medical treatment. Furthermore, most studies have been conducted in the West. This study aimed to uncover the personal experiences of postmenopausal Omani women living with osteoporosis.

METHODS

In this interpretive phenomenological study, a purposive sample of 15 postmenopausal Omani women with osteoporosis was recruited from primary and secondary care facilities in Muscat, Oman. Semi-structured one-to-one interviews were conducted via Zoom and telephone because of coronavirus disease 2019 restrictions. The interviews were audio-recorded, and the Ajjawi and Higgs framework was used to analyse the data thematically.

RESULTS

The following key themes were constructed from the interviews: the impact of osteoporosis on religious practices, cultural and social life, and financial status, and the benefits derived from religious and cultural practices and rituals, including Muslim prayer, recitation of Quranic verses, and herbal remedies to cope with osteoporosis-related pain and suffering.

CONCLUSION

Osteoporosis and fragility fractures have a significant impact on the religious, cultural, and financial lives of postmenopausal Omani women with osteoporosis. Muslim prayers, recitation of Quranic verses, and herbal remedies are coping strategies for pain in this population.

PATIENT OR PUBLIC CONTRIBUTION

Postmenopausal Omani women with osteoporosis participated in this study through interviews and contributed their lived experiences. Orthopaedic doctors helped recruit patients with postmenopausal osteoporosis.

Efficacy of Bushen Jiangu therapy in the treatment of glucocorticoid-induced osteoporosis: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Glucocorticoid-induced osteoporosis (GIOP) is the most common secondary osteoporosis. Bushen Jiangu (BSJG), a classic traditional Chinese medicine (TCM) therapy, is widely used for treatment of GIOP. We conducted a meta-analysis to evaluate the effectiveness and safety of BSJG therapy on the treatment of GIOP.

METHODS

We searched randomized controlled trials (RCTs) of BSJG therapy for GIOP in 10 databases. Methodological quality assessment was performed by using the Cochrane collaboration tool. RevMan v5.3 and Stata v14.0 software were used for performing data analysis. This study was conducted and reported following the PRISMA checklist.

RESULTS

Overall, 14 RCTs with 988 participants met the inclusion criteria. Pooled results indicated that BSJG therapy contributed to a betterment in improving the clinical efficacy rate of GIOP (risk ratio [RR] = 1.22, 95% confidence interval [CI]: 1.14, 1.30, P < .00001). The pooled results also indicated that BSJG therapy increased lumbar spine bone mineral density (LS-BMD) (weighted mean difference [WMD] = 0.21, 95% CI: 0.08, 0.33, P = .001), total hip bone mineral density (TH-BMD) (WMD = 0.16, 95% CI: 0.09, 0.24, P < .0001), and femoral neck bone mineral density (FN-BMD) (WMD = 0.07, 95% CI: 0.03, 0.10, P = .0001). Furthermore, our results indicated that BSJG therapy improved visual analogue scale (VAS) score (WMD = -0.60, 95% CI: -0.97, -0.23, P = .002), parathyroid hormone (PTH) (standardized mean difference [SMD] = -0.93, 95% CI: -1.58, -0.27, P = .006), and N-terminal propeptide of type I precollagen (PINP) (SMD = 0.69, 95% CI: 0.44, 0.95, P < .00001). In terms of safety, there was no significant difference in the adverse events (AEs) between the 2 groups (RR = 1.45, 95% CI: 0.63, 3.31, P = .38).

CONCLUSION

Our analysis indicates that BSJG therapy has a valid and safe effect on the treatment of GIOP in the clinic. However, the results need to be confirmed in more well-designed and large-scale RCTs.

Icariin alleviates osteoarthritis through PI3K/Akt/mTOR/ULK1 signaling pathway

OBJECTIVES

This study aims to investigate the effects of Icariin (ICA) on interleukin-1β (IL-1β)-induced osteoarthritis (OA) and its potential mechanism of action.

METHODS

SW1353 chondrocytes were pretreated with ICA for 2 h, followed by stimulation with IL-1β to mimic OA. Expression levels of matrix metalloproteinases (MMP-3) and collagen II were determined using real-time PCR and Western blot assays. Autophagy activation (by ICA) or inhibition (by shRNA) was determined based on the expression levels of ULK1, Beclin-1, LC3-II/I, and p62, using Western blot analysis. The phosphorylation levels of PI3K, Akt, mTOR, and ULK1 were also detected using Western blot analysis.

RESULTS

IL-1β increased MMP-3 overproduction, induced collagen II degradation, and reduced the level of autophagy-associated proteins, including ULK1, Beclin-1, and LC3-II/I. In contrast, ICA pretreatment attenuated IL-1β-induced MMP-3 overproduction, increased collagen II expression, and induced expression of autophagy-related proteins. ICA also decreased PI3K, Akt, and mTOR phosphorylation, increased the production of ULK1, and induced autophagy. Short hairpin RNA-mediated knockdown of ULK1 led to activation of the PI3K/Akt/mTOR pathway, which reversed the protective effects of ICA.

CONCLUSIONS

Our findings indicate that ICA can induce autophagy by regulating the PI3K/AKT/mTOR/ULK1 signaling pathway. This study suggests that ICA may be effective for treating OA.

Protective Effect and Possible Mechanisms of Tripterygium Glycosides in Patients with Ankylosing Spondylitis: A Systematic Review and Meta-Analysis

Objective

The safety and efficacy of Tripterygium glycosides (TG) were assessed for ankylosing spondylitis (AS) in accordance with the existing literatures.

Materials and Methods

Electronic literature was searched from Chinese VIP databases, Cochrane Library, Chinese Biomedical Literature Database, Wanfang Web of Science, EMBASE, Chinese National Knowledge Infrastructure, and the PubMed for the studies with the publication from the beginning to December 2021. Randomized controlled trials (RCTs) were included only. The major variables of result comprised erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Spinal Pain Visual Analog Score (SP-VAS), Bath Ankylosing Spondylitis Functional Index (BASFI), and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Moreover, the secondary variables of result covered the overall clinical effective rate following the adverse drug reaction (ADR). We carried out the meta-analysis with the use of STATA 12.0 and RevMan 5.3. We used GRADE pro3.6.1 software to assess the quality of evidence.

Results

In general, we covered 15 randomized controlled trials with the focus of 1186 patients. As proven by our meta-analysis, TG as adjuvant therapy or monotherapy decreased the BASDAI, BASFI, SP-VAS, serum CRP, and ESR than control in patients suffering from AS. Additionally, TG treatment visibly improved the overall effective rate in AS. Nevertheless, TG was not found to significantly increase the rate of ADR in contrast to the control.

Conclusion

As indicated by our result, TG may be an option to treat AS. In this paper, we recommended strict trials with high quality and large samples sizes for confirming the finding here.

Comparative Efficacy of Xianling Gubao Capsules in Improving Bone Mineral Density in Postmenopausal Osteoporosis: A Network Meta-Analysis

OBJECTIVE

The clinical efficacy of Xianling Gubao capsule (XLGB) and its combination therapy in the treatment of postmenopausal osteoporosis (PMOP) was systematically evaluated by frequency-based network meta-analysis.

METHODS

We searched the China National Knowledge Infrastructure (CNKI), Wanfang, SinoMed, PubMed, Embase and Cochrane Library databases to identify clinical trials of XLGB for the treatment of PMOP from the establishment of each database to November 22, 2021. The quality of the included studies was evaluated by using the risk of bias assessment tool version 2.0 (Rob 2.0) recommended by Cochrane. Stata 14.0 was applied for statistical analysis of the data, and the surface under the cumulative ranking curve (SUCRA) was used to rank the intervention measures of each outcome index.

RESULTS

This study included 22 clinical trials (including 19 RCTs and 3 non-RCTs) involving 12 drug therapies. According to the results of the network meta-analysis and SUCRA, the best three interventions for improving lumbar bone mineral density (BMD) are XLGB+BP+calcium (83.7%), XLGB+BP (68.5.7%) and XLGB+VD (67.1%). XLGB+calcium was the best combination regimen for improving femoral neck BMD and increasing bone Gla protein (BGP) and alkaline phosphatase (ALP) contents in serum. The SUCRA values of XLGB+calcium for improving the three outcome indicators were 68.0%, 59.5% and 82.1%, respectively.

CONCLUSIONS

The results of this network meta-analysis show that combined application of XLGB can effectively improve BMD and serum BGP and ALP compared to calcium alone, VD or BP. In the future, multicenter, large-sample and double-blind clinical RCTs should be carried out to supplement and verify the results of this study.

Meta-Analysis of the Efficacy and Safety of Alendronate Combined with Atorvastatin in the Treatment of Osteoporosis in Diabetes Mellitus

OBJECTIVE

Diabetes is a chronic disease caused by defective insulin secretion in the body, resulting in metabolic abnormalities with persistent blood glucose elevation. Osteoporosis is the most common diabetes complication. The aim of this study was to perform a meta-analysis of the effects of alendronate combined with atorvastatin compared with alendronate alone in the treatment of osteoporosis in diabetes mellitus.

METHODS

Two researchers independently used PubMed, ScienceDirect, Cochrane Library, Wanfang Data, CNKI, and VIP databases to search for all relevant studies that met the inclusion criteria and used RevMan 5.3 and STATA 16.0 for data analysis.

RESULTS

Fourteen studies that met the inclusion criteria were selected, including 1456 patients. Among the data extracted in this meta-analysis, bone mineral density (BMD) was the primary outcome measurement, while total effective rate, VAS, osteoprotegerin (OPG), bone Gla protein (BGP), bone alkaline phosphatase (BAP), blood P and Ca, and adverse effects were secondary outcome measurements. Our results showed that alendronate combined with atorvastatin is more effective than alendronate alone, with higher BMD, OPG, BGP, and BAP, more significant pain relief, and fewer adverse events.

CONCLUSION

The results of this meta-analysis indicate that alendronate combined with atorvastatin is a better treatment for osteoporosis in diabetes mellitus, showing more effective and higher BMD and fewer adverse events than alendronate alone.

Advances in Use of Nanomaterials for Musculoskeletal Regeneration

Since the worldwide incidence of bone disorders and cartilage damage has been increasing and traditional therapy has reached its limits, nanomaterials can provide a new strategy in the regeneration of bones and cartilage. The nanoscale modifies the properties of materials, and many of the recently prepared nanocomposites can be used in tissue engineering as scaffolds for the development of biomimetic materials involved in the repair and healing of damaged tissues and organs. In addition, some nanomaterials represent a noteworthy alternative for treatment and alleviating inflammation or infections caused by microbial pathogens. On the other hand, some nanomaterials induce inflammation processes, especially by the generation of reactive oxygen species. Therefore, it is necessary to know and understand their effects in living systems and use surface modifications to prevent these negative effects. This contribution is focused on nanostructured scaffolds, providing a closer structural support approximation to native tissue architecture for cells and regulating cell proliferation, differentiation, and migration, which results in cartilage and bone healing and regeneration.
