Prevalence and risk factors of bisphosphonate-associated osteonecrosis of the jaw in prostate cancer patients with advanced disease treated with zole…
2008
Abstract Background In addition to other treatments, patients with prostate cancer (pCA) and bone metastasis receive bisphosphonates. Since 2003, a previously unknown side-effect of bisphosphonates—bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ)—has been described, and frequency has since increased. An exact incidence is still unknown. Objectives The aim of this study was to assess the incidence and additional factors in the development of BP-ONJ. Design, setting, and participants From July 2006 to October 2007, patients with advanced pCA and osseous metastasis receiving bisphosphonate therapy in the Department of Urology or Haematology and Oncology at the Johannes-Gutenberg-Un…
Prevalence of bisphosphonate associated osteonecrosis of the jaws in multiple myeloma patients
2010
Abstract Background Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is an adverse effect of bisphosphonate treatment with varying reported incidence rates. Methods In two neighboring German cities, prevalence and additional factors of the development of BP-ONJ in multiple myeloma patients with bisphosphonates therapy were recorded using a retrospective (RS) and cross-sectional study (CSS) design. For the RS, all patients treated from Jan. 2000 - Feb. 2006 were contacted by letter. In the CSS, all patients treated from Oct. 2006 - Mar. 2008 had a physical and dental examination. Additionally, a literature review was conducted to evaluate all articles reporting on BP-ONJ prevalen…
Exposed necrotic bone in 183 patients with bisphosphonate-related osteonecrosis of the jaw: Associated clinical characteristics
2017
The main objective of our study was to identify oral symptoms and signs most likely to be associated with the exposure of necrotic bone in bisphosphonate-related osteonecrosis of the jaw (BRONJ). The study group consisted of 183 patients with BRONJ. We recorded data on the underlying disease, bisphosphonate used, location of osteonecrosis, symptoms, pain, fistula development, suppuration, infection, exposed necrotic bone, and BRONJ stage. The mean age of the patients was 68.22 ± 12.19 years. The sample included 118 (64.5%) women. Breast cancer and multiple myeloma were the most common underlying diseases, and 50 patients received oral bisphosphonates for osteoporosis. Dental extractions (69…
Medication-related osteonecrosis of the jaw associated with bisphosphonates and denosumab in osteoporosis
2016
OBJECTIVE: To describe the clinical characteristics and evolution of our series of medication-related osteonecrosis of the jaws (MRONJ) associated with denosumab in osteoporotic patients. MATERIAL AND METHODS: We present 10 new cases of MRONJ in patients receiving denosumab for osteoporosis. We describe the mean doses of denosumab, previous bisphosphonate intake, and the clinical characteristics associated with the osteonecrosis, such as local contributing factors, symptoms, and evolution after treatment. RESULTS: The mean number of denosumab doses was 3.4 2.2. In 90% of patients, there was a prior history of oral bisphosphonate intake, with a mean duration of 46.78 25.11 months. The most c…
BRONJ in patients with rheumatoid arthritis: A multicenter case series
2016
Objective: Osteonecrosis of the jaw (ONJ) is a potentially severe adverse effect of various medications (bisphosphonates, anti-resorptive, and anti-angiogenic drugs). ONJ pathogenesis is still unclear although some risk factors have been recognized. Of these, rheumatoid arthritis (RA) has been hypothesized as a potential risk factor for developing ONJ. This observational study will describe a multicenter case series of patients affected with RA and ONJ, and it will attempt to evaluate the association between features of ONJ and pharmacological, systemic, and site variables. Methods: Demographic, pharmacological, and clinical data from 18 RA patients with ONJ were collected and registered fr…
Serum levels of RANKL and OPG, and the RANKL/OPG ratio in bisphosphonate-related osteonecrosis of the jaw: Are they useful biomarkers for the advance…
2017
We determined whether serum levels of Receptor Activator for Nuclear Factor κ B Ligand (RANKL), Osteoprotegerin (OPG), and the RANKL/OPG ratio could be useful biomarkers for the severity of oral lesions in bisphosphonate-related osteonecrosis of the jaw (BRONJ). A case-control study in which Group 1 consisted of 41 patients with BRONJ due to bisphosphonates, and Group 2 consisted of 44 healthy control cases. The plasma levels of RANKL and OPG were analyzed by an ELISA assay. The OPG/RANKL ratio was also calculated. We determined if the mean serum values differed among the different stages of BRONJ. Serum levels of RANKL were lower in Group 1 than in Group 2 (p =0.01), and serum levels of OP…

Effects of zoledronic acid and dexamethasone on early phases of socket healing after tooth extraction in rats : a preliminary macroscopic and microsc…
2018
Background The exact pathogenesis of medication-related osteonecrosis of the jaw (MRONJ) is still unknown. The aim of this paper was to investigate the effects of zoledronic acid and dexamethasone on the early phases of socket healing in rats subjected to tooth extractions. Material and Methods Thirty male Sprague-Dawley rats were divided into 2 groups: pharmacologically treated group (T, n=20) and non-pharmacologically treated group (C, n=10). T group rats received 0.1 mg/Kg of zoledronic acid (ZOL) and 1 mg/Kg of dexamethasone (DEX) three times a week for 10 consecutive weeks. C group rats were infused with vehicle. After 9 weeks from the first infusion, first maxillary molars were extrac…
THE ROLE OF HIGH-DOSE VITAMIN D IN RISK REDUCTION OF OSTEONECROSIS OF THE JAW IN CANCER PATIENTS RECEIVING ZOLEDRONIC ACID
Osteonecrosis of the jaw (ONJ) is a serious complication of oncological patients after or during drug therapy, whose manifestations range from asymptomatic to aspects requiring extensive operative treatment and adversely affecting patient’s qualify of life. Taking in account that the lack of supplementation vitamin D causes hypovitaminosis, increasing bone renewal, losing bone mass, and in severe cases determing osteomalacia (one of the risk factors for ONJ) and that the probability of developing ONJ increases significantly during the first 3 years of treatment, the main objective of the present study is to assess whether the implementation of high-dose vitamin D in oncologic patients treat…
Osteoradionecrosis and Antiresorptive Drug-Related Osteonecrosis of the Jaws
2019
With similar clinical appearances, osteoradionecrosis and antiresorptive drug-related osteonecrosis of the jaw (ARONJ) are different side effects of treatment regimens of mostly malignant diseases. While radiotherapy is usually used to control the progress of locoregional tumors, antiresorptive agents are administered in patients with generalized catabolic bone diseases. Although surgical techniques to treat both diseases are comparable, it should be noted that the pathophysiology is different. For the different genesis of both entities, they are dealt with separately in the following chapter.
