Time to onset of bisphosphonate-related osteonecrosis of the jaws: a multicentre retrospective cohort study

2017

Objectives: Osteonecrosis of the jaw (ONJ) is a potentially severe adverse effect of bisphosphonates (BP). Although the risk of ONJ increases with increasing duration of BP treatment, there are currently no reliable estimates of the ONJ time to onset (TTO). The objective of this study was to estimate the TTO and associated risk factors in BP-treated patients. Subjects and Methods: Retrospective analysis of data from 22 secondary care centres in seven countries relevant to 349 patients who developed BP-related ONJ between 2004 and 2012. Results: The median (95%CI) TTO was 6.0 years in patients treated with alendronate (n = 88) and 2.2 years in those treated with zoledronate (n = 218). Multiv…

Description of a new protocol with application of PRP in post-extraction sockets of a patient treated with aminobisphosphonate

2014

Background. Platelet-rich plasma (PRP), an autologous product rich of growth factors, is an adjunctive bio-material able to promote healing in dental surgery, especially in elderly. It is also used for treating bisphosphonate-related osteonecrosis of the jaw (BRONJ) and for application in post-extraction alveolar site in order to obtain mucosa healing and reduce BRONJ risk. Aim. To describe a dental extraction PRP enriched protocol adopted in a patient treated with aminobisphosphonate in order to evaluate the healing of the post-extraction alveolar site. Case report. An osteoporotic woman (71 yrs), treated with alendronate per os for 10 years and suspended from 1 year, currently with vitami…

Aminobisphosphonates as new weapons for gammadelta T Cell-based immunotherapy of cancer.

2008

BACKGROUND: Activated V gamma 9 V delta 2 T cells are able to kill most tumour cells because of recognition by T cell receptor and natural killer receptors. OBJECTIVE: We discuss the possibility that the intentional activation of gammadelta T cells in vivo by aminobisphosphonates may represent a promising target for the design of novel and highly innovative immunotherapy in cancer patients. METHODS: The antitumoral effects of gammadelta T cells both in vitro and in vivo have been demonstrated suggesting a new therapeutic approach for translation into the clinical setting. RESULTS/CONCLUSION: V gamma 9 V delta 2 T lymphocytes represent a particularly interesting target for immunotherapeutic …

IMAGING FINDINGS SYSTEMATIZATION AND IMAGING STAGING PROPOSAL IN BISPHOSPHONATES ASSOCIATED OSTEOMYLITIS/OSTEONECROSIS OF THE JAWS

2011

INTRODUZIONE I Bifosfonati (BPs), farmaci analoghi al pirofosfato, sono usati nel trattamento dell’osteoporosi, nella malattia di Paget, nel mieloma multiplo e nelle metastasi ossee. Sebbene siano molto utili nella sintomatologia osteolitica, dal 2003 è stata descritta la correlazione tra la loro somministrazione e l’insorgenza dell’osteonecrosi dei mascellari (BRONJ). Il nostro studio si propone di descrivere la superiorità delle immagini TC nei pazienti in cura con BPs affetti da BRONJ, e di raggruppare gli stessi in accordo con una classificazione radiologica basata sulla presenza o meno dei segni dell’osteomielite/osteonecrosi e delle successive complicanze. Si dimostra, inoltre, l’impo…

Medication-Related Osteonecrosis of Jaws (MRONJ) Prevention and Diagnosis: Italian Consensus Update 2020

2020

The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference—held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) (20 October 2018, Ancona, Italy)—after the newest recommendations (2020) on MRONJ were published by two scientific societies (Italian Societies of Maxillofacial Surgery and Oral Pathology and Medicine, SI…

Assessing the risk of osteonecrosis of the jaw due to bisphosphonate therapy in the secondary prevention of osteoporotic fractures

2012

There is evidence that the use oral bisphosphonates can lead to osteronecrosis of the jaws (ONJ). Although the occurrence of ONJ appears rare among oral bisphosphonates (BPs) users, it is important to know that it exists and can be opportunely minimized. INTRODUCTION: The purpose of this study is to evaluate the association between BPs prescribed for the secondary prevention of osteoporotic fractures and the occurrence of ONJ. METHODS: An Italian record linkage claims database with a target population of around 18 million individuals (6 million over 55 years of age) constituted the data source. We conducted a nested case-control study within a cohort of individuals aged 55+ years old, who w…

Improving adherence in osteoporosis: a new management algorithm for the patient with osteoporosis

2011

Introduction: Bisphosphonates are the first-choice treatment for osteoporosis. They effectively increase bone mineral density, reduce markers of bone resorption, and lower the incidence of new fractures in patients with osteoporosis-related fracture. However, the efficacy observed in clinical trials may not be realized in a real-life setting, partly due to poor adherence to therapy, with a significant worsening of clinical outcomes. Several issues contribute to poor adherence to osteoporosis medication, including inconvenient dosing regimens and concerns about possible adverse events. Although strategies to improve adherence have been investigated, new approaches are required. Areas covered…

Onset of MRONJ in Breast Cancer Patients after Switching from Low to High Dose of Bone Modifying Agents Due to Bone Metastases Development: A Single …

2022

Background: Medication-Related Osteonecrosis of the Jaw (MRONJ) is an adverse drug reaction mainly associated to bone modifying agents (BMAs). Breast cancer (BC) is the most frequent cancer worldwide. Its therapy can cause cancer treatment-induced bone loss (CTIBL), commonly treated with BMAs. The aims of this retrospective study are: to describe characteristics of BC patients under BMAs for CTIBL; to record any switch to high-dose BMAs; to assess MRONJ onset and to identify any factors associated with it. Patients: Authors included patients referred for MRONJ prevention to the Unit of Oral Medicine (University Hospital of Palermo). Results: Fourteen female BC patients under low-dose BMAs f…

Novel formulations of oral bisphosphonates in the treatment of osteoporosis

2022

AbstractOral bisphosphonates are a key intervention in the treatment of osteoporosis and in reducing the risk of fragility fractures. Their use is supported by over 3 decades of evidence; however, patient adherence to oral bisphosphonates remains poor in part due to complex dosing instructions and adverse events, including upper gastrointestinal symptoms. This problem has led to the development of novel oral bisphosphonate formulations. Buffered, effervescent alendronate is dissolved in water and so seeks to reduce upper gastro-intestinal adverse events, and gastro-resistant risedronate aims to reduce the complexity of dosing procedure (e.g. fasting prior to consumption) whilst still mainta…
