dc.description.abstractA osteonecrose dos maxilares induzida por bisfosfonatos (OMB) é uma subclasse da condição caracterizada como osteonecrose dos maxilares induzida por medicamentos (OMM), sendo o principal medicamento associado é o AZ, que é fortemente associada a desregulação inflamatória, em especial à superexpressão do fator de necrose tumoral alfa (TNF-α). O infliximabe é um de um anticorpo monoclonal quimérico humano-murino contra o TNF-α. O objetivo desse estudo é avaliar influência do TNF-α por um anticorpo ant-TNF-α, infliximabe, na severidade de osteonecrose dos maxilares induzida por ácido zoledrônico em ratos. Para isso, 24 ratos Wistar machos foram divididos em três grupos (n=8/cada) nos quais foi administrada solução salina (grupo controle) intravascular e por via subcutânea, AZ 0,2mg/kg intravascular e subcutânea de 0,1ml/kg de solução salina (grupo AZ) ou AZ 0,2mg/kg intravascular e 5mg/kg de infliximabe (grupo Inf) por via subcutânea. As administrações intravasculares foram realizadas nos dias 0, 7, 14 e 49 e as subcutâneas foram realizadas semanalmente até o dia 70 (eutanásia). A exodontia foi realizada após 42 dias do início do experimento e foram analisados peso do dente e número de fraturas radiculares. Após eutanásia, 0,2ml de sangue foi coletado para contagem total e diferencial de leucócitos, os animais foram pesados (peso inicial e final do experimento) e as mandíbulas foram coletadas para análise histológica (contagem de células inflamatórias polimorfonucleares (PMN), mononucleares (MN), osteoclastos sadios e apoptóticos e lacunas de osteócitos vazias e preenchidas). Teste ANOVA foi utilizado. Não houve diferença significante no peso dos dentes (p=0,338) e número de fraturas radiculares (p=0,930), mas os animais do grupo AZ e infliximabe apresentaram perda de peso significativa (p<0,001) em relação ao grupo salina e grupo AZ. O percentual de lacunas de osteócitos viáveis foi revertida no grupo Infliximabe comparado com AZ (p=0,002), bem como e o número de células PMN (p= 0,005) e MN(p=0,005). Número de osteoclastos não diferiu entre os grupos (p=0,898). Dessa forma, o tratamento com Infliximabe mostrou redução da inflamação e reversão da OMM, apesar da perda de peso e da hipoglicemia já previstas devido seu efeito hipoglicemiante.pt_BR

dc.description.resumo_abstractBisphosphonate-induced osteonecrosis of the jaw (BIO) is a subclass of the condition characterized as drug-induced osteonecrosis of the jaw (DOM), with the main associated drug being AZ, which is strongly associated with inflammatory dysregulation, especially overexpression of tumor necrosis factor alpha (TNF-α). Infliximab is a human-murine chimeric monoclonal antibody against TNF-α. The aim of this study is to evaluate the influence of TNF-α by an anti-TNF-α antibody, infliximab, on the severity of zoledronic acid-induced osteonecrosis of the jaw in rats. For this purpose, 24 male Wistar rats were divided into three groups (n=8/each) in which saline solution (control group) was administered intravascularly and subcutaneously, AZ 0.2mg/kg intravascularly and 0.1ml/kg subcutaneously of saline solution (AZ group) or AZ 0.2mg/kg intravascularly and 5mg/kg of infliximab (Inf group) subcutaneously. Intravascular administrations were performed on days 0, 7, 14 and 49 and subcutaneous administrations were performed weekly until day 70 (euthanasia). Extraction was performed 42 days after the beginning of the experiment and tooth weight and number of root fractures were analyzed. After euthanasia, 0.2 ml of blood was collected for total and differential leukocyte counts, the animals were weighed (initial and final weight of the experiment) and the mandibles were collected for histological analysis (count of polymorphonuclear inflammatory cells (PMN), mononuclear cells (MN), healthy and apoptotic osteoclasts and empty and filled osteocyte lacunae). ANOVA test was used. There was no significant difference in tooth weight (p=0.338) and number of root fractures (p=0.930), but the animals in the AZ and infliximab groups showed significant weight loss (p<0.001) in relation to the saline group and AZ group. The percentage of viable osteocyte lacunae was reversed in the Infliximab group compared to AZ (p=0.002), as well as the number of PMN (p=0.005) and MN cells (p=0.005). The number of osteoclasts did not differ between the groups (p=0.898). Thus, treatment with Infliximab showed a reduction in inflammation and reversal of OMM, despite the weight loss and hypoglycemia already predicted due to its hypoglycemic effect.pt_BR
