No. of bitstreams: 1 karineandradeoliveirazanini.pdf: 564422 bytes, checksum: 95992f692adb8715af66d371f3987b2f (MD5) Previous issue date: 2016-03-04 / Introdução: Apesar dos avanços recentes no tratamento de pacientes com doença de Crohn (DC), os sintomas oclusivos e suboclusivos observados na presença de estenoses clinicamente significativas permanecem um problema clínico desafiador. Na DC, a identificação de fatores que se associam à redução do risco de cirurgia é importante. Materiais e Métodos: Neste estudo retrospectivo, avaliamos os possíveis fatores preditivos, incluindo os marcadores inflamatórios associados à redução da necessidade de intervenção cirúrgica em pacientes com DC que apresentaram o primeiro episódio de suboclusão intestinal clinicamente resolvido e tratados, subsequentemente, com azatioprina (AZA) durante três anos. Resultados: Trinta e seis pacientes com DC suboclusiva foram incluídos, dos quais, 24 não necessitaram de ressecção intestinal. Nenhum dado demográfico ou clínico associou-se com a resposta à AZA. Apenas a proteína C reativa (PCR) apresentou correlação com a eficácia da AZA. Para cada aumento de 1 mg na PCR, houve uma redução do risco de cirurgia em 8% (RR 0,92; IC 0,86-0,98; p=0,008). O grupo PCR>6 (elevada) apresentou 81% de redução de risco de cirurgia em relação ao grupo PCR<6 (OR 0,19 IC 0,05-0,64; p=0,008). Conclusões: Os pacientes que apresentaram PCR elevada tiveram uma menor taxa de cirurgia a médio e longo prazos durante a terapia com AZA. A PCR pode identificar pacientes com estenoses predominantemente inflamatórias e responsivas ao tratamento clínico. / Background: Despite recent advances in the treatment of patients with Crohn's disease (CD), occlusive and subocclusive symptoms observed in the presence of clinically significant stenosis remains a challenging clinical problem. In inflammatory bowel diseases (IBD), the identification of factors associated with reduced risk of surgery in this context is important. Materials and methods: In this retrospective study, we evaluated the possible predictive factors, including inflammatory markers associated with reduced need for surgical intervention in patients with CD who presented the first episode of clinically solved subocclusion and treated subsequently with azathioprine (AZA) for three years. Results: Thirty-six patients with subocclusive CD were included, of these, 24 has not required bowel resection. No demographic or clinical data associated with the response to AZA. Only C reactive protein (CRP) was correlated with the effectiveness of AZA. For each increase of 1 mg CRP, there was a reduction of surgery risk in 8% (RR 0.92, CI 0.86-0.98; P = 0.008). The CRP group> 6 (elevated) had 81% of surgery risk reduction compared to PCR group <6 (OR 0.19 CI 0.05-0.64; P = 0.008). Conclusions: Patients with elevated CRP has a lower rate of surgery in the medium and long term during therapy with AZA. CRP can identify patients with inflammatory stenosis and responsive to clinical treatment.
