BACKGROUND: Adoptive T-cell therapy relying on conventional T cells transduced with T-cell receptors (TCRs) or chimeric antigen receptors (CARs) has caused substantial tumor regression in several clinical trials. However, genetically engineered T cells have been associated with serious side-effects due to off-target toxicities and massive cytokine release. To obviate these concerns, we established a protocol adaptable to GMP to expand and transiently transfect γ/δ T cells with mRNA...

The aim of the present study was to investigate risk factors for the development of an acute-phase response (APR) associated with the initial zoledronic acid (ZA) infusion in patients undergoing surgery, and to assess whether its onset may be reduced by post-dose administration of low-dose methylprednisolone (MP) or acetaminophen. A retrospective study of patients with osteoporosis who attended the departments of orthopedics and endocrinology of a single hospital and received 5 mg ZA was conducted; the patients included surgical and non-surgical cases...

Only 40% of patients with advanced ovarian cancer survive more than 5 years. We have previously shown that pitavastatin induces regression of ovarian cancer xenografts in mice. To evaluate whether the response of ovarian cancer cells to pitavastatin is potentiated by farnesyl diphosphate synthase inhibitors or geranylgeraniol transferase I inhibitors, we evaluated combinations of pitavastatin with zoledronic acid, risedronate and GGTI-2133 in a panel of ovarian cancer cells. Pitavastatin (IC50 = 0.6-14 μM), zoledronic acid (IC50 = 21-57 μM), risedronate (IC50 > 100 μM) or GGTI-2133 (IC50 > 25 μM) inhibited the growth of ovarian cancer cell cultures...

Medication-related osteonecrosis of the jaw (MRONJ) is a rare but serious and potentially severe side effect of antiresorptive therapy with bisphosphonates or denosumab. Recently, a large animal minipig MRONJ model was introduced which led to early necrotic lesions in the majority of extraction sites after bisphosphonate administration. The aim of this project was to modify the preoperative cumulative bisphosphonate dose (zoledronate) and hereby firstly to demonstrate the reliability and reproducibility of the established model...

There has been no study regarding the effect of a combination of teriparatide (TPTD) and zoledronic acid (ZA) on vertebral fusion. In this study, we investigate the effect of single and combined TPTD and ZA treatment on lumbar vertebral fusion in aged ovariectomized (OVX) rats. Sixty two-month-old female Sprague-Dawley rats were ovariectomized and underwent bilateral L4-5 posterolateral intertransverse fusion after ten months. The OVX rats received vehicle (control) treatment, or ZA (100µg/kg, once), or TPTD (60µg/kg/2 d for 42 d), or ZA + TPTD until they were euthanized at six weeks following lumbar vertebral fusion...

The ocular side-effects of bisphosphonates have the potential to escalate with their widespread use. We report a patient of osteoporosis who was treated with zoledronic acid infusion. He developed ocular pain, redness, watering, photophobia and swelling of both the eyes. He was diagnosed with acute anterior uveitis and conjunctivitis and treated with topical 1% prednisolone acetate and 1% atropine sulphate. The signs of inflammation abated by one week and the steroids were tapered over the next six weeks. There were no further recurrences...

Multiple myeloma (MM) is a haematological malignancy characterised by the clonal proliferation of plasma cells in the bone marrow. More than 80% of patients with MM display evidence of myeloma bone disease (MBD), characterised by the formation of osteolytic lesions throughout the axial and appendicular skeleton. MBD significantly increases the risk of skeletal-related events such as pathologic fracture, spinal cord compression and hypercalcaemia. MBD is the result of MM plasma cells-mediated activation of osteoclast activity and suppression of osteoblast activity...

Clinical use of zoledronate is accompanied with osteonecrosis of the jaw but the pathogenesis is not well understood. We assumed that zoledronate may have cytotoxicity against stem cells of the oral cavity, and in this way helps to initiate or promoting osteonecrosis. Dental pulp stem cells (DPSCs) and gingival fibroblasts (GFs) were isolated from volunteers who were undergoing third molar extraction. The proliferation of DPSCs and GFs was evaluated using thiazolyl blue tetrazolium bromide assay. Effect of zoledronate on apoptosis was determined by propidium iodide staining and western blotting analysis...

OBJECTIVE: The aim of this systematic review and meta-analysis was to evaluate the role of osteogenic coatings (placement of a thin film of organic and inorganic osteoinductive and osteoproliferative materials) on implant surfaces in augmenting bone-to-implant contact (BIC) in osteoporotic bone. DATA SOURCES: To answer the focused question "Do osteogenic coatings on implant surfaces increase BIC in osteoporotic bone?" PubMed/MEDLINE, EMBASE, ISI Web of Knowledge, Scopus, and Google-Scholar databases were searched till June 2017 using different combinations of the following key words: bone-to-implant contact, coating, implant surface, osseointegration, and osteoporosis...

Tibial pseudarthrosis associated with Neurofibromatosis type 1 (NF1) is an orthopedic condition with consistently poor clinical outcomes. Using a murine model that features localized double inactivation of the Nf1 gene in an experimental tibial fracture, we tested the effects of recombinant human bone morphogenetic protein-2 (rhBMP-2) and/or the bisphosphonate zoledronic acid (ZA). Tibiae were harvested at 3 weeks for analysis, at which time there was negligible healing in un-treated control fractures (7% union)...

Phosphorescence O2 analyzer was used to measure calvarial bone cellular respiration (cellular mitochondrial O2 consumption) in Taylor Outbred mice in the presence and absence of zoledronic acid. This potent bisphosphonate inhibits osteoclast-mediated calcium resorption, and its effects on bone respiration have not been previously investigated. The change of O2 concentration with time was measured in closed vials containing phosphate-buffered saline (PBS), 5 mM glucose and 5-25 mg calvarial bone fragments, and it was complex for t = 0-30 h...

OBJECTIVES: Osteoporosis has become an increasing concern for older people as it may potentially lead to osteoporotic fractures. This study is designed to assess the efficacy and safety of ten therapies for post-menopausal women using network meta-analysis. METHODS: We conducted a systematic search in several databases, including PubMed and Embase. A random-effects model was employed and results were assessed by the odds ratio (OR) and corresponding 95% confidence intervals (CI)...

BACKGROUND: For the treatment of patients with cancer to be successful and well-tolerated, the complications and side effects of the disease and its treatment must be treated and limited as far as possible. Summarized recommendations based on the constantly increasing evidence in the area of supportive care must be defined, standardized, and communicated. METHODS: We systematically reviewed the literature on the topics of anemia, neutropenia, nausea/vomiting, diarrhea, oral mucositis, skin toxicity, and peripheral neurotoxicity induced by cancer treatment, as well as osseous complications, extravasation, and side effects of radiotherapy...

BACKGROUND: Prostate cancer (PC) is the most common cancer in Western countries. More than one third of PC patients develop metastatic disease, and the 5-year expected survival in distant disease is about 35%. During the last few years, new treatments have been launched for metastatic castrate-resistant prostate cancer (mCRPC). OBJECTIVES: We aimed to review the current literature on health economic analysis on the treatment of metastatic prostate cancer (mPC), compare the studies, summarize the findings and make the results available to administrators and decision makers...

AIMS: The aim of this work was to examine the antitumor effects and mechanisms of M4IDP, a zoledronic acid derivative, on human colorectal cancer (CRC) HCT116 cells. MAIN METHODS: The effects of M4IDP on proliferation, cell cycle and ROS production were determined by CCK-8 and flow cytometry assays. Annexin-V-FITC/PI, Hoechst 33258, MDC staining assays and Ad-mCherry-GFP-LC3B fluorescence assay were performed to investigate apoptosis and autophagy. The effects of M4IDP on the induction of ER stress as well as the expression of cell cycle, apoptosis and autophagy-related proteins were analyzed by western blot assay...

BACKGROUND: Pemetrexed maintenance therapy holds tremendous potential in improving the survival of patients with advanced pulmonary adenocarcinoma. Major side effects include myelosuppression and cutaneous reactions. However, little data are available on pemetrexed nephrotoxicity. Our case describes clinically relevant renal events leading to treatment discontinuation in routine practice. CASE PRESENTATION: We report a case of a 69-year-old Moroccan man treated for metastatic non-small cell lung cancer...

Milk-Alkali syndrome (MAS) consists of a triad of hypercalcemia, metabolic alkalosis, and acute renal failure. We hereby report a 75-year-old Indian gentleman who presented to our emergency department with a history of generalized weakness and easy fatigability. Investigations were consistent with MAS secondary to calcium carbonate and calcitriol treatment to prevent osteoporosis, aggravated by H1N1 influenza vaccine. The patient was treated with hemodialysis and zoledronate. To our knowledge, this is the first reported case of such association in the literature...

Zoledronate-induced (Aclasta®) uveitis is a rare iatrogen-induced inflammation of ocular structures, which can result in substantial morphological and functional limitations. This case report describes the clinical course of a female patient with zoledronate-induced panuveitis. Additionally, the diagnostic procedure, therapy and follow-up are presented.

The NLRP3 inflammasome senses a variety of signals referred to as danger associated molecular patterns (DAMPs), including those triggered by crystalline particulates or degradation products of extracellular matrix. Since some DAMPs confer tissue-specific activation of the inflammasomes, we tested the hypothesis that bone matrix components function as DAMPs for the NLRP3 inflammasome and regulate osteoclast differentiation. Indeed, bone particles cause exuberant osteoclastogenesis in the presence of RANKL, a response that correlates with NLRP3 abundance and the state of inflammasome activation...
