Comparison of the prophylactic use of ibandronate and its use in early-stage osteonecrosis in rats with steroid-induced osteonecrosis of the femoral head. Jt Dis Relat Surg 2023; 34:640-650. [PMID: 37750269 PMCID: PMC10546859 DOI: 10.52312/jdrs.2023.1096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 06/15/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVES The aim of this study was to investigate the effects of ibandronate before and after the onset of osteonecrosis in rats with steroid-induced osteonecrosis of the femoral head. MATERIALS AND METHODS A total of 24 female Sprague-Dawley rats were used in this study. Three groups were formed with eight rats in each group. The first group was the prophylactic group that received ibandronate treatment before and after the onset of osteonecrosis (Group PT). The second group received ibandronate treatment three weeks after the development of osteonecrosis (Group TAO). The third group was the control group in which osteonecrosis was created, but only normal saline (NS) was given. At the end of the study, all rats were sacrificed, and their right femoral heads were removed, fixed with formalin, and sent for micro-computed tomography. Hematoxylin-eosin (H&E) and immunohistochemical examinations of the right femoral head sections were performed. RESULTS In the PT group, the trabecular thickness was significantly higher compared to those of the TAO and control groups (p<0.05). The trabecular thickness did not significantly differ between the TAO and control groups. The trabecular bone pattern factor was significantly higher in the PT group compared to the control and TAO groups (p<0.05); however, it showed no significant difference between the TAO and control groups. The incidence of type 2 osteonecrosis in the PT and TAO groups was significantly lower than that in the control group (p<0.05). The incidence of tissue-non-specific alkaline phosphatase (TNAPase) immunoreactivity of osteoblast positivity was significantly higher in the PT and TAO groups compared to the control group (p<0.05), whereas the incidence of TRAPase immunoreactivity of osteoclastic positivity was significantly lower in the PT and TAO groups compared to the control group (p<0.05). CONCLUSION Intravenous administration of ibandronate before the onset of the disease was more effective in the treatment of osteonecrosis in rats with steroid-induced osteonecrosis of the femoral head.

Abstract
Study Design Randomized Control Trial. Objective A randomized control trial was planned to aim to assess whether subcutaneous Injection of Teriparatide and Tablet Reunion (combination of Cissus Quadrangularis and Dalbergia sissoo) improves maxillofacial fracture healing as compared to the control group. Methods 24 patients of mandibular fracture with or without concomitant maxillofacial fractures were randomly divided into 3 equal groups (Group 1- Control, Group 2- Tablet Reunion, and Group 3- Injection Teriparatide) and the treatment duration was 4 weeks. Pain, fracture site mobility, bite force, serum markers, and radiographic healing were assessed preoperatively and postoperatively at regular intervals till 12 weeks. Results Group 2 showed early pain relief, although it was insignificant. Group 3 showed the highest anterior bite force at all the time points. Change in mean posterior bite force (PBF) showed a statistically significant increase at 8th week and 12th week in intergroup comparison; however, at 12th week, Group 3 was significantly better than Group 1 and reported the highest posterior bite force compared to other groups. Serum calcium and PTH level showed no significant difference, whereas Serum ALP showed a statistically significant increase in Group 3. The radiographic assessment showed no significant difference among the 3 groups. Conclusions Both the intervention group drugs showed a promising effect on accelerating the fracture healing and improving bite force restoration with the osteoanabolic action; however, early radiographic healing and increased serum osteogenic markers in Group 3 indicate its possible optimistic role in maxillofacial fracture healing.

Abstract
Fracture healing is related to osteogenic differentiation and mineralization. Recently, due to the unwanted side effects and clinical limitations of existing treatments, various natural product-based chemical studies have been actively conducted. Albiflorin is a major ingredient in Paeonia lactiflora, and this study investigated its ability to promote osteogenic differentiation and fracture healing. To demonstrate the effects of albiflorin on osteoblast differentiation and calcified nodules, alizarin red S staining and von Kossa staining were used in MC3T3-E1 cells. In addition, BMP-2/Smad and Wnt/β-catenin mechanisms known as osteoblast differentiation mechanisms were analyzed through RT-PCR and western blot. To investigate the effects of albiflorin on fracture healing, fractures were induced using a chainsaw in the femur of Sprague Dawley rats, and then albiflorin was intraperitoneally administered. After 1, 2, and 3 weeks, bone microstructure was analyzed using micro-CT. In addition, histological analysis was performed by staining the fractured tissue, and the expression of osteogenic markers in serum was measured. The results demonstrated that albiflorin promoted osteoblastogenesis and the expression of RUNX2 by activating BMP-2/Smad and Wnt/β-catenin signaling in MC3T3-E1 cells. In addition, albiflorin upregulated the expression of various osteogenic genes, such as alkaline phosphatase, OCN, bone sialoprotein, OPN, and OSN. In the femur fracture model, micro-CT analysis showed that albiflorin played a positive role in the formation of callus in the early stage of fracture recovery, and histological examination proved to induce the expression of osteogenic genes in femur tissue. In addition, the expression of bone-related genes in serum was also increased. This suggests that albiflorin promotes osteogenesis, bone calcification and bone formation, thereby promoting the healing of fractures in rats.

Abstract
BACKGROUND Breast cancer (BC) is one of the most common malignancies worldwide. Although the burden and mechanisms of endocrine therapy-related bone loss are known, the evidence is scanty regarding the impact of cytotoxic chemotherapy on bone health. We have attempted to summarize the effect of cytotoxic chemotherapy on bone health in BC patients. METHODS A comprehensive literature search was performed via MEDLINE and Cochrane library databases to evaluate the effect of chemotherapy on bone health among women with BC. We included articles related to skeletal-related events, bone mineral density, bone turnover markers, osteoporosis-specific quality of life, bisphosphonate, and other bone-directed therapy. We excluded articles that included patients with metastatic breast cancer and patients receiving hormonal therapy. DISCUSSION Bone microenvironment in cancer is directly or indirectly influenced by clinical, hormonal, nutritional, and treatment factors. Calcitonin, parathyroid hormone, calcitriol, and estrogen are the major hormonal regulators. Bone turnover markers, namely bone formation and resorption markers, have been used to predict bone loss, fracture risk, and monitoring treatment response. Chemotherapeutic drugs such as anthracyclines and taxanes synergistically affect BMD and quality of life. Calcium, vitamin D, bisphosphonates, and denosumab are supplemented to prevent excess bone resorption. Bone-targeted anti-resorptive agents have been studied as potential anticancer agents in the adjuvant treatment of breast cancer. CONCLUSION This review summarizes the negative effect of chemotherapy on bone health of BC patients and the importance of preventing or treating bone loss.

Abstract
INTRODUCTION In a rapidly aging society, the number of people suffering from osteoporosis keeps increasing. However, effective prevention strategies for osteoporosis are not yet currently available. OBJECTIVE In this study, we examined the ameliorative effects of tranexamic acid on osteoporosis in 24-month-old mice. METHODS During the study period, mice were orally administered tranexamic acid 3 times per week. RESULTS Bone mineral density, which is a parameter of osteoporosis, was improved following tranexamic acid administration. In addition, female mice evidenced a stronger phenotypic improvement than male mice. In female mice treated with tranexamic acid, ovary abnormalities were reduced. Furthermore, the levels of transforming growth factor-β, hyaluronic acid, CD44, reactive oxygen species, and apoptosis, as well as the number of infiltrated neutrophils and macrophages in the ovary were lower than those in the control or solvent-administered mice. In addition, 17β-estradiol levels in blood increased when compared with the control or solvent-treated mice. In addition, administration of tranexamic acid to 24-month-old male mice decreased the level of apoptosis in the testis. However, the levels of 17β-estradiol and testosterone in blood increased compared with the control or solvent-administered mice. CONCLUSIONS The use of tranexamic acid had an ameliorative effect on osteoporosis, possibly by protecting ovaries and testes.

Abstract
Calcitonin regulates blood calcium levels and possesses certain clinically useful anti-fracture properties. Specifically, it reduces vertebral fractures in postmenopausal osteoporotic women significantly compared to a placebo. Nevertheless, the use of calcitonin has declined over the years and salmon calcitonin is no longer the first-line treatment for many of its indications. Commercial calcitonin only exists in intranasal or injectable preparations, which are less preferable for patients. Efficacy of a potential oral formulation has been under investigation but achieving adequate bioavailability remains a conundrum and the latest phase III trials have not shown promising evidence justifying its use. Associations with cancer have also derailed this treatment option. Furthermore, the rise of bisphosphonates and, more recently, monoclonal antibodies (such as denosumab), has revolutionised the treatment of osteoporotic fractures. Therefore, we are posed with an interesting question: is calcitonin a treatment of the past? This review aims to explore the reasons behind this paradigm shift and outline the potential role of calcitonin in the management of fractures and other conditions in the years to come.

Abstract
Purpose With improved survival after chemotherapy for acute lymphoblastic leukemia (ALL), it is imperative to maintain good quality of life as part of the management of post-therapy adverse effects. Avascular necrosis of the femoral head (AVNFH) is one such adverse effect. A need exists for a therapy that ameliorates discomfort, provides a productive life, is cost effective, and is joint preservative. We conducted the current study to evaluate the response to bisphosphonate in the nonsurgical management of AVNFH in adolescents and young adults (AYA) who receive treatment for ALL. Materials and Methods This is a retrospective study of 20 AYA patients—34 affected hips—who received zolendronic acid 5 mg intravenously each year along with oral alendronate 70 mg weekly for 3 years. Clinical evaluation was performed by using the Visual Analog Scale and the Harris Hip Score. Radiographs were used to classify the Ficat-Arlet stage, monitor radiologic collapse, and evaluate the rate of progression. Results Pain relief with a drop in the Visual Analog Scale score was observed at a mean duration of 5.2 weeks (range, 3 weeks to 11 weeks) after the start of therapy. Radiologic progression by one grade was observed in 12 hips (35.3%), and only one hip (2.94%) showed progression by two grades. At a mean follow-up of 50.3 months, 31 affected hips (91.1%) had a satisfactory clinical outcome and had not required any surgical intervention. The proportion of hips that required total hip arthroplasty were 0%, 5%, and 22.2% in Ficat-Arlet stage I, II, and III, respectively. Conclusion The combination of intravenous zolendronic acid and oral alendronate provides a pragmatic solution for the management of AVNFH after therapy for ALL in AYA patients. This therapy is safe, effective, and well tolerated.

Abstract
Objective To shorten the natural course of transient osteoporosis of hip (TOH), which is a self-limiting idiopathic condition and requires 6–12 months for the resolution of symptoms, various therapies including treatment with bisphosphonates have been attempted. There exist fewer case reports evaluating the effect of bisphosphonates in TOH and most of them lack radiographic evidence of resolution of disease. The present study was carried out with an aim to evaluate the clinical and radiological outcomes of TOH patients subsequent to treatment with a single dose of zoledronic acid. Methods Data of 19 adult male and non-pregnant female patients with TOH treated with zoledronic acid were included in the study. Efficacy was assessed using changes in clinical signs and symptoms, visual analogue scale pain score, and changes in bone marrow edema (BME) in magnetic resonance imaging (MRI). Results Mean age of the patients was 42.1 years, 17 being males. The mean time of onset of symptom was 4 weeks. Subsequent to treatment, the patients were pain-free and had no limp within an average of 2.8 weeks (range, 2–5 weeks) and remained asymptomatic at a mean follow-up of 35 months (range, 6–54 months). The post-treatment MRI showed resolution of BME in approximately 84% (16/19) of patients at 3 months. No major adverse events were reported. None of the patients progressed to avascular necrosis at their last follow-up. Conclusion Intravenous single dose administration of zoledronic acid provides early pain relief and complete reversal of TOH. Consequently, zoledronic acid is proposed as a new paradigm in the management of TOH.

Abstract
Dysfunction of osteoblastic bone formation and matrix mineralization plays a key role in the pathological development of osteoporosis. The orexin peptide orexin-A, a highly excitatory neuropeptide hormone, possesses various biological functions by activating its specific G protein-coupled receptors, orexin-1 receptor (OX1R) and orexin-2 receptor (OX2R). Here, we report that OX1R but not OX2R was expressed in MC3T3-E1 cells. Importantly, we found that orexin-A accelerated osteoblast differentiation and matrix mineralization in MC3T3-E1 cells, as manifested by elevation of physiological markers of osteoblastic differentiation [alkaline phosphatase (ALP) and osteogenic genes] and Alizarin Red staining, respectively. Importantly, our findings indicated that orexin-A significantly increased the expression of runt-related transcription factor 2 (Runx-2), which is the central transcriptional factor. Orexin-A treatment phosphorylated the kinase p38 mitogen-activated protein kinase (MAPK) in a dose- and time-dependent manner. Also, orexin-induced increase in gene expression (Runx-2, ALP, osteocalcin, and osterix) and matrix mineralization were prevented by the p38 MAPK specific inhibitor SB203580. Additionally, we also revealed that protein kinase D (PKD) is involved in the effects of Orexin-A on p38 MAPK activation and Runx-2 expression. Finally, we found that Orexin-A-induced osteoblastic formation and matrix mineralization and the activation of the PKD/p38 MAPK pathway are mediated by OX1R. Based on these findings, we concluded that activation of OX1R by orexin-A might possess a therapeutic strategy for bone disease. © 2018 IUBMB Life, 70(7):633-641, 2018.

Abstract
INTRODUCTION Pharmacological options to address the imbalance between bone resorption and accrual in osteoporosis include anti-resorptive and osteoanabolic agents. Unique biologic pathways such as the Wnt/β-catenin pathway have been targeted in the quest for new emerging therapeutic strategies. AREAS COVERED This review provides an overview of existing pharmacotherapy for osteoporosis in women and explore state-of-the-art and emerging therapies to prevent bone loss, with an emphasis on the mechanism of action, indications and side effects. EXPERT OPINION Bisphosphonates appear to be a reliable and cost-effective option, whereas denosumab has introduced a simpler dosing regimen and may achieve a linear increase in bone mineral density (BMD) with no plateau being observed, along with continuous anti-fracture efficacy. Abaloparatide, a parathyroid-hormone-related peptide (PTHrP)-analogue, approved by the FDA in April 2017, constitutes the first new anabolic osteoporosis drug in the US for nearly 15 years and has also proven its anti-fracture efficacy. Romosozumab, a sclerostin inhibitor, which induces bone formation and suppresses bone resorption, has also been developed and shown a significant reduction in fracture incidence; however, concerns have arisen with regard to increased cardiovascular risk.

Abstract
Osteoporosis is among the most common forms of age-related diseases, especially for females, which has been a grave public health problem. Drug therapies have shown promising outcomes to promote bone formation and bone density. This study identified a novel potential drug, gossypol, for the treatment of osteoporosis. Treatments of ovariectomy-induced osteoporosis mice with gossypol significantly increased serum osteocalcin and osteoprotegerin (OPG) levels; meanwhile they decreased serum RANKL levels. Microcomputed tomography (microCT) analysis showed that treatment of gossypol improved bone density and strength and decreased bone postyield displacement for both medullar and cortical bones. In vitro experiments also showed that gossypol increased cell viability in a time- and dose-dependent manner. Furthermore, incubation of the osteoblast MC3T3-E1 cells with gossypol inhibited cell apoptosis through intrinsic apoptotic pathway as evidenced by the Annexin V/PI assay, TUNEL assay, biochemical analysis, and western blot assays. Moreover, the classical Wnt/β-catenin signaling pathway was found to be regulated by gossypol treatments. Inhibition of Wnt/β-catenin signaling reversed the prevention effects of gossypol in osteoporosis. Our findings provided novel clues for the treatment of osteoporosis in clinic.

Abstract
OBJECTIVE To estimate the association between osteoporosis treatment and severe periodontitis in postmenopausal women. METHODS This cross-sectional study comprised of 492 postmenopausal women, 113 women in osteoporosis treatment, and 379 not treated. Osteoporosis treatment consisted of systemic estrogen alone, or estrogen plus progestin, and calcium and vitamin D supplements, for at least 6 months. Severe periodontitis was defined as at least two interproximal tooth sites with clinical attachment loss of at least 6 mm, and at least one interproximal site with probing depth of at least 5 mm; and dental caries experience was measured using the decayed, missing, and filled teeth (DMFT) index. Analysis included descriptive statistics and Poisson multivariate analysis with robust variance. RESULTS Women receiving osteoporosis treatment had less periodontal probing depth, less clinical attachment loss, and less gingival bleeding than women not receiving treatment for osteoporosis (P ≤ 0.05). In the osteoporosis treatment group, the estimated mean DMFT index score was approximately 20, the most frequent component being the number of missing teeth, and in the nontreated group, the DMFT index was approximately 19. The prevalence of severe periodontitis was 44% lower in the osteoporosis treatment group than in the nontreatment group. The prevalence ratioadjusted was 0.56, 95% confidence interval was 0.31 to 0.99 (P = 0.05), after adjustments for smoking, age, family income, and visit to the dentist. CONCLUSIONS The results suggest that women treated with estrogen for postmenopausal osteoporosis have a lower prevalence of severe periodontitis than women not receiving treatment.

Dietary phlorizin enhances osteoblastogenic bone formation through enhancing β-catenin activity via GSK-3β inhibition in a model of senile osteoporosis. J Nutr Biochem 2017; 49:42-52. [PMID: 28866105 DOI: 10.1016/j.jnutbio.2017.07.014] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2017] [Revised: 06/30/2017] [Accepted: 07/24/2017] [Indexed: 01/21/2023]
Abstract
Osteoporosis is one of the most prevalent forms of age-related bone diseases. Increased bone loss with advancing age has become a grave public health concern. This study examined whether phlorizin and phloretin, dihydrochalcones in apple peels, inhibited senile osteoporosis through enhancing osteoblastogenic bone formation in cell-based and aged mouse models. Submicromolar phloretin and phlorizin markedly stimulated osteoblast differentiation of MC3T3-E1 cells with increased transcription of Runx2 and osteocalcin. Senescence-accelerated resistant mouse strain prone-6 (SAMP6) mice were orally supplemented with 10 mg/kg phlorizin and phloretin daily for 12 weeks. Male senescence-accelerated resistant mouse strain R1 mice were employed as a nonosteoporotic age-matched control. Oral administration of ploretin and phorizin boosted bone mineralization in all the bones of femur, tibia and vertebra of SAMP6. In particular, phlorizin reduced serum RANKL/OPG ratio and diminished TRAP-positive osteoclasts in trabecular bones of SAMP6. Additionally, treating phlorizin to SAMP6 inhibited the osteoporotic resorption in distal femoral bones through up-regulating expression of BMP-2 and collagen-1 and decreasing production of matrix-degrading cathepsin K and MMP-9. Finally, phlorizin and phloretin antagonized GSK-3β induction and β-catenin phosphorylation in osteoblasts and aged mouse bones. Therefore, phlorizin and phloretin were potential therapeutic agents encumbering senile osteoporosis through promoting bone-forming osteoblastogenesis via modulation of GSK-3β/β-catenin-dependent signaling.

Abstract
β-thalassemia is the most common single gene disorder worldwide, in which hemoglobin
β-chain production is decreased. Today, the life expectancy of thalassemic patients is
increased because of a variety of treatment methods; however treatment related complications
have also increased. The most common side effect is osteoporosis, which usually
occurs in early adulthood as a consequence of increased bone resorption. Increased bone
resorption mainly results from factors such as delayed puberty, diabetes mellitus, hypothyroidism,
ineffective hematopoiesis as well as hyperplasia of the bone marrow, parathyroid
gland dysfunction, toxic effect of iron on osteoblasts, growth hormone (GH) and
insulin-like growth factor-1 (IGF-1) deficiency. These factors disrupt the balance between
osteoblasts and osteoclasts by interfering with various molecular mechanisms and result
in decreased bone density. Given the high prevalence of osteopenia and osteoporosis in thalassemic patients and
complexity of their development process, the goal of this review is to evaluate the molecular
aspects involved in osteopenia and osteoporosis in thalassemic patients, which may
be useful for therapeutic purposes.

Abstract
Expanding medical knowledge increases the potential risk of medical errors in clinical practice. We present, OPAD, a clinical decision support system in the field of the medical care of osteoporosis. We utilize clinical information from international guidelines and experts in the field of osteoporosis. Physicians are provided with user interface to insert standard patient data, from which OPAD provides instant diagnostic comments, 10-year risk of fragility fracture, treatment options for the given case, and when to offer a follow-up DXA-evaluation. Thus, the medical decision making is standardized according to the best expert knowledge at any given time. OPAD was evaluated in a set of 308 randomly selected individuals. OPAD's ten-year fracture risk computation is nearly identical to FRAX (r = 0.988). In 58% of cases OPAD recommended DXA evaluation at the present time. Following a DXA measurement in all individuals, 71% of those that were recommended to have DXA at the present time received recommendation for further investigation or specific treatment by the OPAD. In only 5.9% of individuals in which DXA was not recommended, the result of the BMD measurement changed the recommendations given by OPAD.

Abstract
Osteoporosis is a chronic disease of the osseous system characterized by decreased bone strength and increased fracture risk. It is due to an imbalance in the dynamic ongoing processes of bone formation and bone resorption. Currently available osteoporosis therapies like bisphosphonates, selective estrogen receptor modulators (SERMs), and denosumab are anti-resorptive agents. Parathyroid hormone analogs like teriparatide are the only anabolic agents currently approved for osteoporosis treatment. The side-effects and limited efficacy of the presently available therapies has encouraged extensive research into the pathophysiology of the disease and newer drug targets for its treatment. The novel anti-resorptive agents being developed are newer SERMs, osteoprotegerin, c-src (cellular-sarcoma) kinase inhibitors, αVβ3 integrin antagonists, cathepsin K inhibitors, chloride channel inhibitors, and nitrates. Upcoming anabolic agents include calcilytics, antibodies against sclerostin and Dickkopf-1, statins, matrix extracellular phosphoglycoprotein fragments activin inhibitiors, and endo-cannabinoid agonists. Many of these new drugs are still in development. This article provides an insight into the emerging drugs for the treatment of osteoporosis.
