Abstract [sv]

Syfte: Syftet med den systematiska översikten är att granska och sammanställa tillgänglig kunskap om cellulära mekanismer involverade i utvecklingen av läkemedelsrelaterad osteonekros i käkarna orsakad av zoledronsyra. Material och metod: En systematisk översikt. En elektronisk sökning gjordes i databaserna MEDLINE/PubMed and Scopus den 3e juni 2019. Resultat: Totalt 804 artiklar identifierades, varav 11 inkluderades i fulltext utifrån inklusion- och exklusionskriterier. Samtliga artiklar studerade olika humana celler in-vitro. Denna studie har funnit att zoledronsyra i varierande koncentrationer ökade apoptos, minskade migration och proliferation hos epitelceller, fibroblaster, osteoblaster, endotelceller och stamceller från pulpan vilket vidare påverkar homeostasen lokalt i vävnaden. Zoledronsyrans effekter var både koncentration- och tidsberoende.    Slutsats: Läkemedelsrelaterad osteonekros i käkarna är mest troligt en multifaktoriell process innefattande förlängd sårläkning, kronisk inflammation och förändrad benremodellering till följd av behandling med zoledronsyra. Vidare forskning behövs för att kartlägga exakt patofysiologi i syfte till att kunna optimera omhändertagandet och behandlingsmetod.

Abstract [en]

Aim: The aim of this systematic review was to present an up to date review of available publications investigating the cellular mechanisms initiating the development of medication-related osteonecrosis of the jaw caused by zoledronic acid. Material and method: A systematic review. Electronic searches of MEDLINE/PubMed and Scopus were conducted on the 3rd of June 2019. Results: A total of 804 publications were identified, of which 11 were eligible for the inclusion criteria and were therefore included in this study. All the included studies were in vitro studies investigating various human cells. The current review found that zoledronic acid in various concentrations increased apoptosis, decreased migration and proliferation of epithelial cells, fibroblasts, osteoblasts, endothelial cells and dental pulp stem cells and therefore can affect local tissue homeostasis. The consequences of zoledronic acid were found to be both time and dose dependent. Conclusion: The pathophysiology of medication-related osteonecrosis of the jaw is in all likelihood a multifactorial process involving prolonged wound healing, chronic inflammation and altered bone remodeling, following administration of zoledronic acid. Further research is needed to identify the exact pathophysiology to optimize management and treatment. Key words: medication-related osteonecrosis of the jaw, MRONJ, pathophysiology, zoledronate, zoledronic acid.
