ABSTRACT

SUMMARY OBJECTIVE: The effects of Certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α, on experimentally induced acute pancreatitis (AP) were examined. METHODS: Thirty-six Wistar Albino male rats were randomly divided into four groups. Group I was the control group and no medication administered to this group. Group II was the Certolizumab group, and 100 ml/kg serum physiologic administered into the biliopancreatic duct and a single dose of 10 μg Certolizumab was simultaneously administered intraperitoneally. Acute pancreatitis was induced with a retrograde injection of 3% Na taurocholate into the common biliopancreatic duct in the study (Group III) and treatment (Groups IV) groups. Rats were sacrificed 72 hours later. Serum amylase, lipase, lactate dehydrogenase activities, along with pancreatic histopathology, were examined. RESULTS: Certolizumab treatment significantly decreased serum amylase, lipase, and LDH levels; histopathologically edema, hemorrhage, parenchymal necrosis, fat necrosis, and infiltration scores; immunohistochemically MDA, MPO, TNF-α and Caspase-3 activity. CONCLUSION: The results support the idea that certolizumab might be beneficial for the severity of AP.


RESUMO OBJETIVO: Os efeitos de Certolizumab, um anticorpo monoclonal pegilado para o fator de necrose tumoral α, na pancreatite aguda induzida experimentalmente (PA) foram examinados. MÉTODO: Trinta e seis ratos Wistar Albino foram divididos aleatoriamente em quatro grupos. O Grupo I foi considerado o grupo controle e não recebeu medicação; o Grupo II foi o grupo Certolizumab e recebeu 100 ml/kg de soro fisiológico administrado no ducto biliopancreático e dose única de 10 mg Certolizumab administrada por via intraperitoneal simultaneamente. A pancreatite aguda foi induzida com uma injeção retrógrada de uma solução de 3% taurocolato de sódio aplicada no ducto biliopancreático comum nos grupos de estudo (Grupo III) e tratamento (Grupos IV). Os ratos foram sacrificados 72 horas depois. As atividades séricas de amilase, lipase, lactato desidrogenase, juntamente com a histopatologia pancreática, foram examinadas. RESULTADOS: O tratamento com Certolizumab diminuiu significativamente os níveis séricos de amilase, lipase e LDH; edema histopatológico, hemorragia, necrose paranquimatosa, necrose gordurosa e escores de infiltração; atividade imuno-histoquímica de MDA, MPO, TNF-α e Caspase-3. CONCLUSÃO: Estes resultados suportam a ideia de que o Certolizumab pode ser benéfico para a gravidade da PA.
