Chinese herbal medicine for the treatment of endocrine therapyrelated osteoporosis among patients with breast cancer:A systematic review and meta-analysis

Objective:To assess the efficacy and safety of combining traditional Chinese medicine(TCM),specifically Chinese herbal medicine(CHM),with Western medicine(WM),compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis(BCET-OP)by meta-analysis.Methods:Thirty-eight randomized controlled trials involving 2170 participants were analyzed.Eight databases were searched for articles published between inception and December 2023.Quality assessment was performed using the Risk of Bias 2 tool.Results:Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density(BMD)(P<.001,mean difference(MD)=0.07,95%confidence interval(CI):0.06 to 0.08),lumbar vertebrae T-score(P=.0005,MD=0.21,95%CI:0.09 to 0.33)and collum femoris BMD(P=.01,MD=0.10,95%CI:0.02 to 0.19).No significant difference was observed between the groups in the collum femoris T-score and estradiol levels.Bone gla-protein levels were significantly increased in the TCM-WM group(P=.0002,MD=0.52,95%CI:0.25 to 0.79).Beta-CrossLaps decreased significantly in the TCM-WM group(P=.0008,MD=−0.10,95%CI:−0.16 to−0.04).No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase,in procollagen type I N-terminal propeptide,and in the Kupperman index.The visual analog score(VAS)was decreased in the TCM-WM group compared to the WM group(P<.001,MD=−1.40,95%CI:−1.94 to−0.87).No significant difference in adverse events was observed between the two groups.Conclusion:Combining CHM with WM in patients with BCET-OP significantly improved BMD,T-score,and certain bone turnover markers and reduced the VAS score,indicating potential benefits for bone health and related pain.Adverse event analysis revealed no differences between the groups,supporting the feasibility of the combination therapy.However,further research,particularly in diverse populations,is required.

Research trends in exercise therapy for the treatment of pain in postmenopausal osteoporosis over the past decade:A bibliometric analysis

BACKGROUND Postmenopausal osteoporosis(PMOP)is the most common form of primary osteoporosis among women,and the associated pain often drives patients to seek clinical intervention.Numerous studies have highlighted the unique clinical benefits of exercise therapy(ET)in alleviating PMOP-related pain.However,bibliometric analyses examining collaboration,development trends,and research frontiers in the field of ET for PMOP pain remain scarce.AIM To explore the research trends in ET for pain treatment in PMOP patients over the past decade.METHODS All scholarly works were meticulously sourced from the Science Citation Index-Expanded within the prominent Web of Science Core Collection.Utilizing the capabilities of CiteSpace 6.2.R5,we conducted a thorough analysis of publications,authors,frequently cited scholars,contributing nations,institutions,journals of significant citation,comprehensive references,and pivotal keywords.Additionally,our examination explored keyword cooccurrences,detailed timelines,and periods of heightened citation activity.This comprehensive search,from 2014 through 2023,was completed within a single day,on October 11,2023.RESULTS In total,2914 articles were ultimately included in the analysis.There was a rapid increase in annual publication output in 2015,followed by stable growth in subsequent years.Boninger,Michael L,is the most prolific author,whereas Ware JE has the most citations.The United States’global influence is significant,surpassing all other nations.The University of California System and Harvard University are the most influential academic institutions.J Bone Joint Surg Am is the most influential journal in this field.“Spinal cord injury”is the keyword that has garnered the most attention from researchers.The developmental pattern in this field is characterized by interdisciplinary fusion,with different disciplines converging to drive progress.CONCLUSION The academic development of the field of ET for pain in PMOP has matured and stabilized.Clinical management and rehabilitation strategies,along with the mechanisms underlying the relationship between ET and bone resorption analgesia,continue to be the current and future focal points of research in this field.

Integrative analysis of bone-formation associated genes and immune cell infiltration in osteoporosis, and the prediction of active ingredients in targeted traditional Chinese medicine

Objective To explore the differential expression and mechanisms of bone formation-related genes in osteoporosis(OP)leveraging bioinformatics and machine learning methodologies;and to predict the active ingredients of targeted traditional Chinese medicine(TCM)herbs.Methods The Gene Expression Omnibus(GEO)and GeneCards databases were employed to conduct a comprehensive screening of genes and disease-associated loci pertinent to the pathogenesis of OP.The R package was utilized as the analytical tool for the identification of differentially expressed genes.Least absolute shrinkage and selection operator(LASSO)logis-tic regression analysis and support vector machine-recursive feature elimination(SVM-RFE)algorithm were employed in defining the genetic signature specific to OP.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses for the selected pivotal genes were conducted.The cell-type identification by estimating rela-tive subsets of RNA transcripts(CIBERSORT)algorithm was leveraged to examine the infiltra-tion patterns of immune cells;with Spearman’s rank correlation analysis utilized to assess the relationship between the expression levels of the genes and the presence of immune cells.Coremine Medical Database was used to screen out potential TCM herbs for the treatment of OP.Comparative Toxicogenomics Database(CTD)was employed for forecasting the TCM ac-tive ingredients targeting the key genes.AutoDock Vina 1.2.2 and GROMACS 2020 softwares were employed to conclude analysis results;facilitating the exploration of binding affinity and conformational dynamics between the TCM active ingredients and their biological targets.Results Ten genes were identified by intersecting the results from the GEO and GeneCards databases.Through the application of LASSO regression and SVM-RFE algorithm;four piv-otal genes were selected:coat protein(CP);kallikrein 3(KLK3);polymeraseγ(POLG);and transient receptor potential vanilloid 4(TRPV4).GO and KEGG pathway enrichment analy-ses revealed that these trait genes were predominantly engaged in the regulation of defense response activation;maintenance of cellular metal ion balance;and the production of chemokine ligand 5.These genes were notably associated with signaling pathways such as ferroptosis;porphyrin metabolism;and base excision repair.Immune infiltration analysis showed that key genes were highly correlated with immune cells.Macrophage M0;M1;M2;and resting dendritic cell were significantly different between groups;and there were signifi-cant differences between different groups(P<0.05).The interaction counts of resveratrol;curcumin;and quercetin with KLK3 were 7;3;and 2;respectively.It shows that the interac-tions of resveratrol;curcumin;and quercetin with KLK3 were substantial.Molecular docking and molecular dynamics simulations further confirmed the robust binding affinity of these bioactive compounds to the target genes.Conclusion Pivotal genes including CP;KLK3;POLG;and TRPV4;exhibited commendable significant prognostic value;and played a crucial role in the diagnostic assessment of OP.Resveratrol;curcumin;and quercetin;natural compounds found in TCM;showed promise in their potential to effectively modulate the bone-forming gene KLK3.This study provides a sci-entific basis for the interpretation of the pathogenesis of OP and the development of clinical drugs.

Bone anabolics in osteoporosis: Actuality and perspectives

Vertebral and nonvertebral fractures prevention is the main goal for osteoporosis therapy by inhibiting bone resorption and/or stimulating bone formation.Antiresorptive drugs decrease the activation frequency,thereby determining a secondary decrease in bone formation rate and a low bone turnover.Bisphosphonates are today’s mainstay among antiresorptive treatment of osteoporosis.Also,oral selective estrogen receptor modulators and recently denosumab have a negative effect on bone turnover.Agents active on bone formation are considered a better perspective in the treatment of severe osteoporosis.Recombinant-human parathyroid hormone(PTH)has showed to increase bone formation and significantly decrease vertebral fractures in severe patients,but with a modest effect on nonvertebral fractures.The study of Wnt signaling pathway,that induces prevalently an osteoblastic activity,opens large possibilities to antagonists of Wnt-inhibitors,such as sclerostin antibodies and dickkopf-1 antagonists,with potential effects not only on trabecular bone but also on cortical bone.

Osteoporosis and fractures in liver disease: Relevance, pathogenesis and therapeutic implications

It is being increasingly recognized that patients with liver disease develop bone loss that can be severe enough to lead to atraumatic fractures and thus markedly diminish life quality and expectancy. The estimated prevalence for liver-related osteoporosis is between 20-420/100000 of the general population, and fractures between 60-880/100000. It should be kept in mind that up to 40% of patients with chronic liver disease may experience a fracture. The pathogenic mediators include fibronectin, insulin like growth factor-I, and various cytokines, but decreased vitamin D and/or treatment with corticosteroids contribute to worsening bone health. Despite the advances in bone biology that have shed some light on the pathogenesis of this bone loss, treatment options remain nonspecific and tightly linked to treatments of other forms of osteoporosis. Thus, treatment should include calcium and vitamin D supplementation in all patients with chronic liver disease. Therapy with bisphosphonates should be considered, especially in patients receiving corticosteroids. This review focuses on the prevalence of this entity as well as the evidence available with regard to the pathogenesis of bone loss in liver disease, the diagnostic steps required in all patients, and the therapeutic options available.

中医药靶向线粒体动力学防治骨质疏松研究进展

骨质疏松症(osteoporosis,OP)是一种机体慢性代谢性骨疾病,主因机体骨质细胞内成骨与破骨平衡关系失衡而发生。线粒体是机体内为细胞活动提供能量的重要细胞器,能够调整和影响机体细胞内众多压力源和代谢需求,极大程度地影响着机体细胞的分化及死亡过程。线粒体动力学内涵了线粒体融合、分化裂变、自噬和转运的变化过程,这对OP的发生起着关键作用。当前研究表明,在人体正常生理情况下,线粒体动力学积极调控骨质细胞的成骨与破骨之间的平衡关系,对骨质状态的稳定起重要作用。反之,在病理情况下,线粒体动力学的障碍会打破成骨与破骨之间的平衡关系,相当程度上决定了OP的发生。因此在此背景下,线粒体动力学日益成为OP的靶向治疗研究热点。笔者查阅国内外相关文献,就线粒体动力学与OP的相关性及中医药靶向治疗作一综述,以期为进一步防治骨质疏松症提供参考和策略。

Effect of androgen deprivation therapy on bone mineral density in prostate cancer patients

Aim: To evaluate the effect of androgen deprivation therapy (ADT) on bone mineral density (BMD) in prostate cancer patients. Methods: Forty-nine prostate cancer patients with their BMD determined were divided into two groups: the non-treated group included 21 patients before the commencement of ADT and the treated group, 28 patients, who had received ADT for more than 1 year. BMD was measured by dual energy X-ray absorptiometry (DEXA) in the lumbar spine (L2-4) and femoral neck. Results: Thirteen (62 %) non-treated and 23 (82 %) treated patients fulfilled the BMD criteria for osteopenia or osteoporosis. Z scores for age-matched control in lumbar spine and femoral neck were -0.9 ± 0.7 and -0.6 ± 0.5, respectively, in the treated group, and -1.8 ± 1.1 and-1.6 ± 1.0 , respectively, in the non-treated group, the differences between the two groups were highly significant (P<0.01). Conclusion: Prostate cancer patients who received ADT for more than 1 year had a significantly lower BMD in the lumbar spine and femoral neck than those before the beginning of ADT.

Bilateral sequential femoral neck stress fractures in young adult with HIV infection on antiretroviral therapy: A case report

BACKGROUND Femoral neck stress fractures are rarely encountered among young adults and are often associated with either repetitive excessive loading or underlying bone pathology.Preliminary research has indicated human immunodeficiency virus(HIV)/antiretroviral therapy(ART)as predisposing agents to osteopenia and osteoporosis related complications.We report a case of HIV/ART induced insufficiency fracture in a resource limited setting in Central India.Our aim is to increase awareness and promote screening of HIV/ART related osteopenia and osteoporosis in order to prevent catastrophic orthopaedic complications.CASE SUMMARY A 35-year-old HIV positive male presented with a stress fracture of left femoral neck.The patient was on ART and reported no comorbidities.He went on to be successfully managed surgically.However,during work-up osteopenia of the contralateral proximal femur was recognised using Singh’s Index.Six months post-op the patient presented with right-sided femoral-neck stress fracture.At this stage the patient was nonconcordant with ART and denied surgical fixation.CONCLUSION In the absence of co-morbidities,several mechanisms of HIV/antiretroviral therapy may have played a role in predisposing our patient towards such a presentation.We recommend routine screening all HIV-infected patients for osteopenia,especially in younger individuals.In low resource settings and district hospitals,pelvis radiograph&Singh’s index can be used for screening.

Low-level laser therapy enhances the number of osteocytes in calvaria bone defects of ovariectomized rats

Background : Osteoporosis can make bone repair difficult. Low-level laser therapy( LLLT) has been shown to be a promising tool for bone neoformation. This study aimed to analyze the effect of LLLT on calvaria bone defects of ovariectomized rats using stereology. Methods : Fifty-four Wistar rats were subjected to bilateral ovariectomy, and bone defects were created in calvaria after 150 days. The animals were divided into nine groups(n = ?6 per group), and 24 hours after the bone defects were created they received three, six or 12 sessions of LLLT at 0, 20 or 30 J/cm 2, using a 780-nm low-intensity GaAlAs laser. One-way ANOVA followed by Tukey ' s post hoc test was used for data processing. A difference of P < 0.05 was considered statistically significant. The parameters evaluated were osteocyte density( Nv_(ost)), total osteocyte number( Nto ost), trabecular surface density( Sv_t), and trabecular surface area( Sa_t). Results : Data obtained showed that Nto ost, Sv t, and Sa t in group G2 rats were significantly different from G1(0 J/cm^2)( P < 0.05). Compared to group G4, G5 presented higher values for the parameters Sv t and Sa t, and G6 presented significantly higher values for almost all the analyzed parameters( Nv _(ost), Nto_(ost), Sv_t, and Sa t)( P < 0.05). Compared to group G7, G8 showed a higher value only for the parameter Sa t, and G9 showed significantly higher values for parameters Nv ost, Nto ost, Sv_t, and Sa_t. Conclusion : We conclude that LLLT stimulated bone neoformation and contributed to an increase in the total number of osteocytes, especially with a laser energy density of 30 J/cm^2 given for six and 12 sessions.
