Rhizomelia and Impaired Linear Growth in a Girl with Juvenile Paget Disease: The Natural History of the Condition.

In ultra-rare bone diseases, information on growth during childhood is sparse. Juvenile Paget disease (JPD) is an ultra-rare disease, characterized by loss of function of osteoprotegerin (OPG). OPG inhibits osteoclast activation via the receptor activator of nuclear factor-κB (RANK) pathway. In JPD, overactive osteoclasts result in inflammatory-like bone disease due to grossly elevated bone resorption. Knowledge on the natural history of JPD, including final height and growth, is limited. Most affected children receive long-term antiresorptive treatment, mostly with bisphosphonates, to contain bone resorption, which may affect growth. In this study, we report the follow-up of height, growth velocity, and skeletal maturation in a 16-year-old female patient with JPD. The patient was treated with cyclic doses of pamidronate starting at 2.5 years of age and with 2 doses of denosumab at the age of 8 years, when pamidronate was paused. In the following years, a sustainable decline in a height z-score and a stunted pubertal growth spurt; despite appropriate maturation of the epiphyseal plates of the left hand, the proximal right humerus and both femora were observed. Whether this reflects the growth pattern in JPD or might be associated to the antiresorptive treatments is unclear, since there is very limited information available on the effect of bisphosphonates and denosumab on growth and the growth plate in pediatric patients. Studies are needed to understand the natural history of an ultra-rare bone disease and to assess the effects of antiresorptive treatment on the growing skeleton.

Atrial fibrillation in patients treated with intravenous zoledronic or pamidronic acid: a pharmacoepidemiological study.

OBJECTIVE: Atrial fibrillation (AF) may be triggered by intravenous bisphosphonates (IVBPs) such as zoledronic acid or pamidronic acid. Our objective was to confirm the association between AF and IVBPs in a real-life large pharmacovigilance database. DESIGN: A systematic analysis of VigiBase, the World Health Organization's pharmacovigilance database. METHODS: Analysis of adverse events reported as 'atrial fibrillation' (according to the Medical Dictionary for Drug Regulatory Activities) associated with the use of zoledronic acid or pamidronic acid, in VigiBase, the World Health Organization's global Individual Case Safety Report (ICSR) database. All ICSRs reporting AF associated with zoledronic acid or pamidronic acid were included in a disproportionality analysis determining the lower end of the 95% credibility interval for the information component (IC025), showing a statistical association when >0. RESULTS: 530 ICSRs reporting on the association between AF and IVBPs were extracted. Bayesian disproportionality analysis detected a significant association between AF and use of zoledronic acid (IC025 = 1.83) and pamidronic acid (IC025 = 2.16). Further analysis of these ICSRs determined that AF was severe in 85.0% of cases and with a mortality of 17.7%. The risk of severe AF was increased (OR: 2.98 (95% CI: 1.17-7.57), P = 0.02) following zoledronic acid vs pamidronic acid, after adjustment for age and gender. CONCLUSIONS: This is the first VigiBase pharmacoepidemiological study confirming the association between IVBPs and AF. Most AF were severe, with a high frequency of lethal outcome. The risk of severe AF was increased following zoledronic acid use compared to pamidronic acid, advocating for a cautious use of IVBPs.

Intravenous pamidronate for treatment of osteogenesis imperfecta in Indian children.

Osteogenesis imperfecta is characterised by low bone mineral density, bone fragility, fractures and deformity. We present five such children treated with intravenous pamidronate, which resulted in a decrease of fracture rate and increase in spinal bone mineral density.

Monthly intravenous alendronate treatment can maintain bone strength in osteogenesis imperfecta patients following cyclical pamidronate treatment.

Objectives Osteogenesis imperfecta (OI) is a skeletal dysplasia characterized by recurrent fractures due to congenital bone fragility. The only bisphosphonate approved for OI in Japan is pamidronate (PAM). To investigate whether monthly intravenous alendronate (ALN) infusions can maintain bone strength in OI children following cyclical PAM treatment. Methods A prospective and non-inferiority study was conducted. Eight school-age OI patients aged 8.5±2.0 years who were treated with cyclical PAM for 6.0±2.3 years were enrolled and switched to monthly intravenous ALN (0.030 mg/kg/month). Changes in L1-4 bone mineral density (BMD) Z-scores, fracture rates, and bone turnover markers for 12 months were analyzed. Results Average BMD Z-scores were -3.0±1.9, -2.9±2.0, and -2.2±2.0 in 12 months before enrollment, at enrollment, and after 12 months of ALN treatment, respectively. BMD Z-scores increased significantly during treatment with both PAM and ALN (p=0.012), and the effect of ALN was not inferior to that of PAM (p=0.67). There was no change in fracture rates (p=0.86) and bone turnover markers during the 12 months before and after enrollment. Additionally, ALN showed no remarkable side effects. Conclusions Our results suggest that monthly intravenous ALN can maintain bone strength after primary usage of cyclical PAM. We concluded that monthly intravenous ALN as a maintenance treatment following cyclical PAM administration can be an option for OI children.

The Influence of Local Pamidronate Application on Alveolar Dimensional Preservation after Tooth Extraction-An Animal Experimental Study.

The aim of this randomized, controlled animal exploratory trial was to investigate the influence of local application of aminobisphosphonate pamidronate during the socket preservation procedure. Mandibular premolars were extracted in five Göttingen minipigs. Two animals underwent socket preservation using BEGO OSS (n = 8 sockets) and three animals using BEGO OSS + Pamifos (15 mg) (n = 12 sockets). After jaw impression, cast models (baseline, eight weeks postoperative) were digitized using an inLab X5 scanner (Dentsply Sirona) and the generated STL data were superimposed and analyzed with GOM Inspect 2018 (GOM, Braunschweig). After 16 weeks, the lower jaws were prepared and examined using standard histological methods. In the test group (BEGO OSS + pamidronate), buccooral dimensional loss was significantly lower, both vestibulary (0.80 ± 0.57 mm vs. 1.92 ± 0.63 mm; p = 0.00298) and lingually (1.36 ± 0.58 mm vs. 2.56 ± 0.65 mm; p = 0.00104) compared with the control group (BEGO OSS). The test group showed a significant difference between vestibular and lingual dimensional loss (p = 0.04036). Histology showed cortical and cancellous bone in the alveolar sockets without signs of local inflammation. Adjuvant application of pamidronate during socket preservation reduces alveolar dimensional loss significantly. Further investigations with regard to dose-response relationships, volume effects, side effects, and a verification of the suitability in combination with other bone substitute materials (BSMs) are necessary.

Radiation therapy combined with bone-modifying agents ameliorates local control of osteolytic bone metastases in breast cancer.

Bone-modifying agents (BMAs) are frequently used for the treatment of bone metastases. Both BMA and radiation therapy (RT) are effective; however, there are few studies that have evaluated the efficacy of the combination treatment. We evaluated the effectiveness of RT + BMA in breast cancer-induced osteolytic bone metastasis as compared to BMA alone. A total of 43 lesions in 25 patients were evaluated. The median follow-up period was 18 (range, 2-90) months. None of the lesions was treated with chemotherapy or molecular targeted drugs during the follow-up period for evaluating the local response. Patients with complete or partial response were considered as responders, while those with stable or progressive disease were considered as non-responders. The rate of response with RT + BMA was significantly higher than that with BMA alone (P = 0.001). The cumulative incidence rate of response at 6 months was 54.4% in the RT + BMA group and 27.5% in the BMA alone group. The median time to response was 4 (range, 2-11) months in the RT + BMA group and 6 (range, 4-16) months in the BMA alone group. The overall survival rate in the responder group (83.1% at 1 year) was significantly higher than that in the non-responder group (37.5% at 1 year) (P = 0.029). In conclusion, RT combined with BMA was found to be more effective than BMA alone for the treatment of osteolytic bone metastasis, which thereby improves the prognosis.

Pretreatment with Pamidronate Decreases Bone Formation but Increases Callus Bone Volume in a Rat Closed Fracture Model.

Clinical concerns have been raised over prior exposure to bisphosphonates impairing fracture healing. To model this, groups of male Wistar rats were assigned to saline control or treatment groups receiving 0.15 mg/kg (low dose), 0.5 mg/kg (medium dose), and 5 mg/kg (high dose) Pamidronate (PAM) twice weekly for 4 weeks. At this point, closed fractures were made using an Einhorn apparatus, and bisphosphonate dosing was continued until the experimental endpoint. Specimens were analyzed at 2 and 6 weeks (N = 8 per group per time point). Twice weekly PAM dosing was found to have no effect on early soft callus remodeling at 2 weeks post fracture. At this time point, the highest dose PAM group gave significant increases in bone volume (+ 10%, p < 0.05), bone mineral content (+ 30%, p < 0.01), and bone mineral density (+ 10%, p < 0.01). This PAM dosing regimen showed more substantive effects on hard callus at 6 weeks post fracture, with PAM treatment groups showing + 46-79% increased bone volume. Dynamic bone labeling showed reduced calcein signal in the PAM-treated calluses (38-63%, p < 0.01) and reduced MAR (32-49%, p < 0.01), suggesting a compensatory reduction in bone anabolism. These data support the concept that bisphosphonates lead to profound decreases in bone turnover in fracture repair, however, this does not affect soft callus remodeling.

Severe hypercalcaemia due to household cleaner ingestion.

We report the case of a 59-year-old man with a history of type 2 diabetes, hypertension and chronic kidney disease who presented with symptomatic severe hypercalcaemia (calcium 15.8 mg/dL) and acute kidney injury. Evaluation revealed that the hypercalcaemia was not mediated by parathyroid hormone (PTH), PTH-related peptide or 1,25-hydroxyvitamin D. Adrenal insufficiency was subsequently diagnosed and was initially thought to be the aetiology of the hypercalcaemia. He was treated with intravenous fluid, pamidronate and started on hydrocortisone with resolution of his hypercalcaemia. Over the next several months, despite adherence to hydrocortisone therapy, the patient continued to have recurrent severe hypercalcaemia requiring hospitalisation. Additional laboratory evaluation showed similar results to the initial evaluation. On further questioning, the patient admitted to routinely ingesting the household cleaning product Comet, which contains a large amount of calcium. Psychiatric assessment confirmed the diagnosis of pica. The patient eventually discontinued ingestion of Comet with resolution of his hypercalcaemia.

Multifaceted approach to a rare clinical case of calciphylaxis in a renal transplant recipient.

Calcific uremic arteriolopathy (CUA) is a highly morbid condition usually found in ESRD patients that has rarely been reported after renal transplantation and renal function restoration. Furthermore, little is known about the optimal management of CUA in this setting. Herein, we report on the clinical case of AB, a 70-year-old woman who developed CUA after renal transplantation and renal function restoration. However, other risk factors for CUA such as diabetes and warfarin treatment, due to mechanical aortic valve implantation, were present. Thirty-eight months after renal transplantation she developed erythema and livedo reticularis in both legs and a gradually enlarging skin ulcer in the right leg. A skin biopsy of the ulcer showed features compatible with the CUA, such as sub-intimal calcification and luminal obstruction of the small dermal arterioles, tissue ischemia and signs of adipocytes degeneration. A multidisciplinary approach was adopted, including medical and non-medical treatments such as surgical debridement and vacuum-assisted closure therapy. Medical treatments included a five weeks course of once a week intravenous infusion of pamidronate and intravenous sodium thiosulfate (STS) at increasing doses. Four months after beginning the therapy with STS, a complete healing of the ulcer on the right leg and the disappearance of the livedo reticularis on the left leg was noted. In conclusion, although rare CUA may develop also in renal transplanted patients, a timely and combined therapeutic approach is essential for its resolutive treatment. Sodium thiosulfate therapy has proven to be effective and tolerated.

Severe bilateral Legg-Calvé-Perthes resolved with pamidronate in combination with casts, physiotherapy and adductor tenotomy: a pictorial essay over 11 years.

We describe an 11-year prospective clinical and radiologic course of a 6-year-old boy with bilateral Legg-Calvé-Perthes disease, who was treated with intravenous pamidronate (IV-PAM). His baseline radiographs showed grade IV avascular necrosis/Catterall stage IV, and at worst he progressed to lateral pillar/Herring stage C bilaterally. His disease initially was extremely functionally limiting with expected poor outcome with eventual joint replacement. Because IV-PAM stops bone breakdown and allows for ongoing bone formation while revascularisation of bone occurs, we hypothesised that IV-PAM could act as an adjunct to traditional treatment to help heal the femoral heads. Our patient received nine once monthly doses of IV-PAM (1 mg/kg/dose) over 13 months, along with Petrie/broomstick casts and physiotherapy. Remarkably, over time, his femoral heads healed. Now, at 11-year follow-up, he has excellent functional and radiologic outcome with congruence between femoral head and acetabulum, no residual osteonecrosis and minimal loss of femoral head sphericity.

Treatment of chronic recurrent multifocal osteomyelitis with bisphosphonates in children.

OBJECTIVES: Assessment of bisphosphonates efficiency in the therapy of NSAIDs-refractory Chronic Recurrent Multifocal Osteomyelitis. METHODS: Retrospective analysis of records of patients treated for Chronic Recurrent Multifocal Osteomyelitis between 2012 and 2018. RESULTS: Between 2012 and 2018, 76 children and adolescents were diagnosed with Chronic Recurrent Multifocal Osteomyelitis in our department. All patients underwent an initial course of NSAIDs therapy that provided a remission in 46% of cases. Of 41 NSAIDs-resistant cases, 7 patients were male and 34 were female. Disease started meanly in the age of 10. Most frequently pain localised in foot, clavicle and hip. In presented group, pamidronate was administered intravenously in the dose of 1mg/kg/day for 3 days. Patients received 6 series (1-17 series) on average with mean interval of 10 weeks (4-14 weeks). Our observations demonstrated rapid decrease of symptoms intensity after first dose of pamidronate with relapse of pain after 3-4 weeks. The frequency of pamidronate dosage was dependent of patient's symptoms. No serious adverse effects were reported. We finished the therapy after complete remission of symptoms and complete bone remodelling in imaging. Of 41 patients, 32 achieved remission and 9 continue their therapy. In remission group patients received 7 series of pamidronate on average and their treatment lasted meanly 20 months. CONCLUSIONS: Pamidronate is a safe and efficient method of CRMO therapy, particularly in cases refractory to NSAIDs treatment. Treatment with pamidronate provides both symptomatic relief as well as normalisation of bone morphology.

Bisphosphosphonate-calcium phosphate cement composite and its properties.

Calcium phosphate cement (CPC) has been studied extensively due to its bioactivity and biodegradability. CPC is typically made by a combination of multiple calcium phosphates that form a paste that sets and hardens in the body after being combined with either water or an aqueous solution. It is highly moldable and easily manipulated, and CPCs possess osteoconductive properties. Due to these characteristics, CPCs offer great promise in bone grafting applications. CPC combined with drugs has a great potential as drug delivery system and has been studied extensively. In this review we have focused on Bisphosphonate-CPC drug delivery system. In addition, we introduce and discuss the potential of studying other bisphosphonates.

WNT1-associated osteogenesis imperfecta with atrophic frontal lobes and arachnoid cysts.

A rare form of osteogenesis imperfecta (OI) caused by Wingless-type MMTV integration site family 1 (WNT1) mutations combines central nervous system (CNS) anomalies with the characteristic increased susceptibility to fractures. We report an additional case where arachnoid cysts extend the phenotype, and that also confirms the association of intellectual disabilities with asymmetric cerebellar hypoplasia here. Interestingly, if the cerebellum is normal in this disorder, intelligence is as well, analogous to an association with similar delays in a subset of patients with sporadic unilateral cerebellar hypoplasia. Those cases typically appear to represent vascular disruptions, and we suggest that most brain anomalies in WNT1-associated OI have vascular origins related to a role for WNT1 in CNS angiogenesis. This unusual combination of benign cerebellar findings with effects on higher functions in these two situations raises the possibility that WNT1 is involved in the pathogenesis of the associated sporadic cases as well. Finally, our patient reacted poorly to pamidronate, which appears ineffective with this form of OI, so that a lack of improvement is an indication for molecular testing that includes WNT1.

Primary isolated hepatosplenic sarcoidosis mimicking malignancy and causing symptomatic hypercalcaemia.

This is a case of a 67-year-old woman, known to have multiple medical problems, mainly papillary thyroid cancer status post-total thyroidectomy and cervical neck dissection in addition to radioactive iodine currently in remission for 1 year, who presented to the hospital with severe weakness and fatigue. The initial workup showed significant hypercalcaemia and suppressed Parathyroid hormone (PTH). The patient was treated with hydration and pamidronate and her hypercalcaemia and symptoms improved. The differential was wide, however, a CT scan of the chest, abdomen and pelvis did show multiple liver and splenic nodular lesions; therefore, malignancy was the highest possible diagnosis. Biopsy of the splenic lesion confirmed the diagnosis of sarcoidosis. Therefore, the patient was diagnosed with primary isolated nodular hepatosplenic sarcoidosis mimicking malignancy and causing significant symptomatic hypercalcaemia.

Non-uraemic calciphylaxis successfully treated with pamidronate infusion.

Calciphylaxis is a rare and potentially fatal disease that affects the subcutaneous layer of the skin. It is a calcific vasculopathy induced by a systemic process that causes occlusion of small blood vessels. The mortality rate for individuals diagnosed with calciphylaxis is estimated between 52% and 81% with sepsis being the leading cause of death. Uraemic calciphylaxis and its known effective treatments are well documented in the literature. Unfortunately, there is no known effective treatment for non-uraemic calciphylaxis. Most of the current treatments for non-uraemic calciphylaxis are derived from uraemic calciphylaxis treatment protocols. We report a case of a 75-year-old female with calciphylaxis on the right lower extremity who was successfully treated with four pamidronate infusions in addition to local wound care. This case represents a non-uraemic calciphylaxis wound successfully treated with pamidronate infusions and standard wound care, and suggests that IV pamidronate can be an effective treatment option.

A case of severe, irreversible hypocalcemia after one dose of pamidronate administered for hypercalcemia of malignancy.

This is a case report of a patient who developed severe, irreversible hypocalcemia after receiving one dose of pamidronate 90 mg for hypercalcemia of malignancy. Hypocalcemia is a known risk of bisphosphonate treatments, but the incidence of severe hypocalcemia is rare, and the risk factors are well established. However, in the treatment of hypercalcemia of malignancy, the treatment objective is to reduce the elevated serum calcium level, and the bisphosphonate is usually given as one time dose only. The potential for developing severe hypocalcemia may not be considered a significant concern in this setting compared to the setting of the treatment of bone metastasis, where the baseline serum calcium level is not elevated and the bisphosphonate is administered at a regular interval of every three to four weeks. Furthermore, there is unawareness of prevalence of vitamin D deficiency in cancer patients, especially in those with advanced cancer, which may lead to inadvertent, severe hypocalcemia from bisphosphonate treatment. The objective of this case report is to bring awareness to the risk of severe hypocalcemia in patients with hypercalcemia of malignancy and the high prevalence of unrecognized vitamin D deficiency in cancer patients.

Pre-treatment with Pamidronate Improves Bone Mechanical Properties in Mdx Mice Treated with Glucocorticoids.

Duchenne muscular dystrophy (DMD) is an X-linked disease of progressive muscle deterioration and weakness. Patients with DMD have poor bone health which is partly due to treatment with glucocorticoids, a standard therapy to prolong muscle function that also induces bone loss. Bisphosphonates are used to treat adults at risk of glucocorticoid-induced osteoporosis but are not currently used in DMD patients until after they sustain fractures. In this study, C57BL/10ScSn-mdx mice, a commonly used DMD animal model, received continuous glucocorticoid, prednisone treatment (0.083 mg/day) from 5 to 10 weeks of age. Pre-treatment with the bisphosphonate pamidronate started at 4 weeks of age over a period of 2 weeks or 6 weeks (cumulative dose 8 mg/kg for both) to assess the effectiveness of the two dosing regimens in ameliorating glucocorticoid-induced bone loss. Mdx mice treated with prednisone had improved muscle function that was not changed by pamidronate treatment. Glucocorticoid treatment caused cortical bone loss and decreased cortical bone strength. Both 2 and 6 week pamidronate treatment increased cortical thickness and bone area compared to prednisone-treated Mdx mice, however, only 2 week pamidronate treatment improved the strength of cortical bone compared to that of glucocorticoid-treated Mdx mice. In the trabecular bone, both pamidronate treatments significantly increased the amount of bone, and increased the ultimate load but not the energy to fail. These results highlight the importance of when and how much bisphosphonate is administered prior to glucocorticoid exposure.

Sodium thiosulfate and pamidronate for treatment of calciphylaxis: case report / Tiosulfato de sodio y pamidronato para el tratamiento de calcifilaxis: reporte de caso

Abstract Introduction: Calciphylaxis is an infrequent disease that almost exclusively affects patients with chronic kidney disease, although cases have been observed in patients without renal function impairment. The diagnosis is mainly made by clinical manifestations and subsequently confirmed by radiological and histological study. The optimal treatment is not known, although there is a consensus that a multifactorial approach is required. Clinical Case: A 68-year-old woman on hemodialysis for 2 years, who presented a painful nodular lesion in the left thigh, a skin biopsy was performed resulting in a diagnosis of calciphylaxis. Treatment and Outcome: Treatment was started with intravenous sodium thiosulfate. Pamidronate is added intravenously, three months later, due to an unfavorable evolution. After 6 months of treatment, improvement in nodular lesions and healing of the ulcerated lesion was observed to be generally well tolerated treatment. Conclusion: The combined treatment of sodium thiosulfate, pamidronate and calcitomimetics has been effectiveand safe for the treatment of calciphylaxis, inducing complete remission.

Resumen: Introducción: La calcifilaxis es una enfermedad infrecuente que afecta casi exclusivamente a pacientes con insuficiencia renal, aunque se han observado casos en pacientes sin deterioro de la función renal. El diagnóstico es clínico confirmándose con estudio radiológico e histológico. No se conoce con exactitud el tratamiento óptimo, aunque hay consenso en que se requiere un abordaje multifactorial. Caso Clínico: Mujer de 68 años en hemodiálisis desde hace 2 años, que presenta una lesión nodular dolorosa en muslo izquierdo, resultando un diagnostico compatible con calcifilaxis, tras biopsia cutánea. Tratamiento y resultado: Inicia tratamiento con tiosulfato de sodio vía venosa. Tres meses más tarde y ante la evolución desfavorable, se añade al tratamiento pamidronato vía intravenosa. Tras 6 meses de tratamiento se observa mejoría de las lesiones nodulares y cicatrización de la lesión ulcerada, habiéndose experimentado buena tolerancia. Conclusión: El tratamiento combinado de tiosulfato de sodio, pamidronato y calcimiméticos ha resultado efectivo y seguro para el tratamiento de la calcifilaxis, induciendo su remisión completa.

Does Local Ibandronate and/or Pamidronate Delivery Enhance Osseointegration? A Systematic Review.

PURPOSE: To our knowledge from indexed literature, the present study is the first one to systematically review the influence of local delivery of pamidronate (PAM) and/or ibandronate (IBA) on osseointegration enhancement. The aim of the present systematic review was to assess the efficacy of IBA and/or PAM local delivery (topically or coating on implants surfaces) in promoting osseointegration. MATERIALS AND METHODS: To address the focused question, "Does local IBA and/or PAM delivery enhances osseointegration?," indexed databases were searched without time or language restrictions up to and including May 2016 using various combinations of the following keywords: "pamidronate," "ibandronate," "bisphosphonates," "osseointegration," and "topical administration." Letters to the Editor, historic reviews, commentaries, case series, and case reports were excluded. RESULTS: Fifteen studies were included. Fourteen studies were performed in animals and 2 were clinical trials. One study reported an experimental model and a clinical trial in the same publication. Results from 12 experimental studies and 2 clinical studies reported improved biomechanical properties and/or osseointegration around implants with PAM and/or IBA. Two experimental studies showed that PAM and/or IBA did not improve osseointegration. CONCLUSIONS: On experimental grounds, local IBA and/or PAM delivery seems to enhance osseointegration; however, from a clinical perspective, further randomized control trials are needed to assess the effectiveness of IBA and PAM in promoting osseointegration around dental implants.
