MRONJ Dotaz Zobrazit nápovědu
The Medication-Related Osteonecrosis of the Jaw (MRONJ) is a disease that may appear in patients treated by bisphosphonates or other antiresorptive therapy such as denosumab. Both conservative and surgical approach to its treatment are possible. This paper summarizes a case of a patient with MRONJ who, after being unsuccessfully treated by a conservative therapy, was completely cured by the surgical treatment. A detailed step-by-step analysis of the case is provided along with recommendations for therapy according to our up-to-date experience with this type of affliction.

INTRODUCTION: The purpose of this European multicenter study was to describe the general characteristics and risk factors of MRONJ lesions as well as their clinical diagnosis and management at different European Oral and Maxillofacial Surgery centers, in order to minimize selections biases and provide information about the epidemiology, etiopathogenesis, and the current trends in the treatment of MRONJ across Europe. MATERIALS AND METHODS: The following data were registered for each patient: gender; age at MRONJ diagnosis; past medical history; indication for antiresorptive or antiangiogenic therapy; type of antiresorptive medication; local risk factor for MRONJ; MRONJ Stage; anatomic location and symptoms; treatment; surgical complications; recurrence. RESULTS: A total of 537 patients (375 females, 162 males) with MRONJ were included. Statistically significant associations were found between patients with metastatic bone disease and recurrences (P < 0.0005) and between advanced MRONJ stages (stages 2 and 3) and recurrences (P < 0.005). Statistically significant associations were also found between male gender and recurrences (P < 0.05), and between MRONJ maxillary sites and recurrences (P < 0.0000005). CONCLUSIONS: A longer mean duration of antiresorptive medications before MRONJ onset was observed in patients affected by osteoporosis, whereas a shorter mean duration was observed in all metastatic bone cancer patients, and in particular in those affected by prostate cancer with bone metastases or multiple myeloma. Surgery plays an important role for the management of MRONJ lesions.

Both denosumab (DMB) and bisphosphonates (BPs), antiresorptive drugs (ARDs) used for the treatment of osteoporosis and oncological disorders, are known for their potential to cause medication-related osteonecrosis of the jaws (MRONJ). Besides ARDs, statins were recently associated with MRONJ development, especially in patients taking higher doses of statins for a longer period of time. Here, we report a case of a female patient with osteoporosis using statins and treated with alendronate for 3 years who rapidly developed MRONJ stage III after only a single low dose of DMB. After partial maxillectomy complete healing was observed without any recurrence. We performed a literature review of cases with MRONJ triggered by a single low dose of DMB, with or without previous application of other ARDs. Only six similar cases of patients who developed MRONJ after a single low dose of DMB following previous BP therapy have been reported so far. Besides these, literature reports one patient who developed MRONJ after a single dose of DMB following romosozumab treatment and five cases developing MRONJ after a single dose of DMB even without any previous ARD treatment. We suggest that before DMB therapy is initiated, all factors predisposing to MRONJ development should be considered.

Bisfosfonáty (ďalej BF) patria do skupiny antiresorpčných látok. Inhibujú diferenciáciu osteoklastov a ich zrenie, redukujú resorpciu kostí. Indikované sú hlavne pri myeloma muptiplex, m. Paget, pri kostných metastázach pri Ca prostaty, prsníka, obličiek a pod., a pri osteoporóze. Ich negatívom je, že niekedy vyvolávajú osteonekrózu čeľustí, Americkou asociáciou pre oromaxilofaciálnu chirurgiu pomenovanú ako BRONJ – bisphosponate related osteonecrosis of the jaws resp. MRONJ – medication related osteonecrosis of the jaws. Incidencia osteonekrózy pri p. o. užívaní BF je 1 percento a menej, pri užívaní i. v. 1 až 10 percent. Liečba už vzniknutej BRONJ/MRONJ je komplikovaná a zdĺhavá. Dôležitá je preto prevencia jej vzniku sanovaním zubov a ústnej dutiny už pred začatím liečby BF. Nutná je úzka spolupráca ošetrujúceho lekára, ktorý antiresorpčné lieky ordinuje, so zubným lekárom. Veľmi pozitívne je, ak farmaceut pri vydávaní lieku upozorní pacienta na nutnosť konzultácie u zubného lekára.
Significant group of antiresorptive substances are bisphosphonates (abbr. BP). They inhibit diferentiation and maturation of osteoclasts, decrease bone resorption. Main indications of the BP are multiple myeloma, Paget´s disease, bone metastases by cancer of prostata, breast cancer, kidney malignancies etc. and by osteoporosis. As negative effect of the BP reveals development of jaw osteonecrosis in some cases, by the American Association for Oromaxilofacial Surgery named BRONJ – bisphosponate related osteonecrosis of the jaws or MRONJ – medication related osteonecrosis of the jaws respectively. Incidence of the osteonecrosis by oral use of the BP is above 1 percent or less, by intravenous application ranges from 1 to 10 percents. Therapy of the developed BRONJ/MRONJ is complicated and long lasting. Therefore the prevention is prefered by sanation of teeth and the oral cavity before start of the BP treatment. Close cooperation is required within the general physician who prescribes the antiresorptive substances and the dentist. Very positive is when the annoucement of the need of consultation with the dentist of the patient is made by the pharmacist.
BACKGROUND: Medication - related osteonecrosis of the jaw (MRONJ) is a rare but serious complication of antiresorptive and/or antiangiogenic therapy. It mainly affects oncological patients, however, it can occur in patients with metabolic bone diseases, although this is less frequent. These lesions not only significantly impair the quality of life but can also have impact on the treatment of any underlying disease. In some rare cases MRONJ can be life-threatening. There is still no ideal consensus for treatment, though surgical therapy has been mostly preferred in recent years. MATERIALS AND METHODS: A monocentric retrospective evaluation of surgical therapy of MRONJ in osteoporotic patients, treated in the time period 3/2014-3/2018 using the uniform department-specific protocol. RESULTS: 26 osteoporotic patients with 32 MRONJ lesions of stage 1 (9%), stage 2 (75%) and stage 3 (16%) were treated surgically. The maxilla: mandibula ratio was 1:2.2, in 19% of patients there was multiple jaw involvement. 69.2% of patients had received bisphosphonates, 15.4% denosumab and 15.4% had a history of both types of antiresorptive treatment. Complete healing was observed in all patients, in 9% of cases by secondary intention in the mean period of 6 weeks. The mean follow-up was 20.5 months. CONCLUSION: The presented protocol for surgical therapy was effective in the management of all MRONJ stages in the osteoporotic patients described here. The surgery is indicated as an early treatment to prevent complications and the progression of the lesions. It leads to improvement in quality of life and option to resume antiresorptive therapy if interrupted.

The use of antiangiogenic and antiresorptive medications, particularly in patients with cancer or osteoporosis, can lead to osteonecrosis of the jaw following tooth extraction, trauma or arising spontaneously- A condition known as medication-related osteonecrosis of the jaw (MRONJ). In this article, we present a unique case of MRONJ in a patient with no history of antiresorptive or antiangiogenic drug use, who was instead taking the anti-interleukin 17-A (Secukinumab) medication for severe psoriasis. This association has not been previously reported in the literature.

OBJECTIVES: Medication-related osteonecrosis of the jaw (MRONJ) is defined as exposed bone in the maxillofacial region persisting for more than eight weeks in patients who are or were treated with antiresorptive or antiangiogenic agents and had no radiation therapy to the craniofacial region or obvious metastatic disease of the jaws. It is a recognised side effect of antiresorptive or antiangiogenic medication. To date, there is no specific gold standard treatment for MRONJ cases. The aim of this study was to evaluate the successful rate of surgical treatment with adjuvant local application of platelet rich fibrin. METHODS: 40 patients treated with necrotic bone resection and adjuvant local application of platelet-rich fibrin (PRF) were included. Treatment outcomes were evaluated after 12 months. RESULTS: The outcome of surgical treatment was successful in 34 of all 40 patients (85%), in 12 months follow-up. If we evaluate only cases where removal of all necrotic bone was possible the success rate was increased to 94%. A significant association between size of necrotic bone and treatment response was found (P=0.014, Wilcoxon rank sum test with continuity correction). CONCLUSIONS: Surgical treatment of MRONJ with adjuvant local PRF application proved to be very effective and safe, especially in early stages when all necrotic bone can be easily removed.
