Efficacy of complementary treatment with autologous platelet concentrates and/or mesenchymal stem cells in chemical osteonecrosis of the jaw. Systematic review of the literature

The aim of this systematic review was to establish the current status of the subject and find out what scientific evidence we have on the use of autologous plasma concentrates (APCs) and mesenchymal stem cells (MSCs) as complementary therapies at the management of Medication-related Osteonecrosis of the jaw (MRONJ). We performed a literature search of articles published between December 2019 to January 2020 in electronic databases, in accordance to PRISMA system. The variables analyzed were: the number of patients, age, sex, medical history, origin of MRONJ, imaging studies, treatment performed, and evolution of MRONJ. The articles included in the review were grouped into two groups (Group A Therapy with APCs and Group B Therapy with APCs and MSCs). Newcastle-Ottawa scale (NOS) was used to assess the quality of the articles. Fisher's exact test was used to evaluate eventual differences between groups. Of the 306 patients who were included, 297 belonged to Group A and 9 to Group B. In our sample, women predominated against men and no significant differences in age were observed. Osteoporosis was the most frequent underlying disease in both groups. The most common origin of MRONJ was oral surgery in group A. Conservative surgery was performed in all patients, but complementary treatment was applied in different ways in each group. The resolution of the pathology was achieved in 90% of cases in both groups without significant differences between them. The mean score of the reviewed studies at NOS was 4. There are currently no published scientific data that can sufficiently support the use of APCs and MSCs for the treatment of established MRONJs. xe002;C 2021 Elsevier Masson SAS.

Automated summary

The aim of this systematic review was to establish the current status and scientific evidence for the use of autologous plasma concentrates (APCs) and mesenchymal stem cells (MSCs) as complementary therapies in the management of Medication-related Osteonecrosis of the jaw (MRONJ). The review found that although there were differences in the treatment approaches in the two groups, both groups achieved a pathology resolution rate of 90% for MRONJ.
