C-reactive protein is associated with postoperative outcomes in patients with intestinal Behçet’s disease

Abstract

Abstract Background Patients with intestinal Behçet’s disease (BD) frequently undergo intestinal resections, which significantly affects postoperative morbidity and mortality. The aim of this study was to identify the association between C-reactive protein (CRP) levels and postoperative outcomes in patients with intestinal BD who underwent surgical bowel resection. Methods Patients who were diagnosed with intestinal BD and underwent intestinal surgery due to BD at Severance Hospital between November 2005 and April 2018 were retrospectively investigated. Clinical relapse was defined as a disease activity index of BD (DAIBD) > 40, existence of newly added medications, re-hospitalization, or re-operation related to intestinal BD. The relationship between CRP level and postoperative outcomes was analyzed, and a receiver operating characteristic (ROC) curve was drawn to specify a cut-off value. Results Ninety patients with intestinal BD were included. Among them, 44 were male (48.9%), and the median age at diagnosis was 38 years (range, 11–69 years). The median total disease follow-up duration was 130 months (range, 3–460 months). Forty patients (44.4%) underwent laparoscopic surgery. A higher CRP level immediately after surgery was significantly associated with postoperative complications (OR 1.01, 95% CI 1.004–1.018, p < 0.01), re-operation (hazard ratio [HR] 1.01, 95% CI 1.005–1.020, p < 0.01), and re-admission (HR 1.01, 95% CI 1.006–1.017 p < 0.01). The ROC curve showed that CRP predicts the risk of postoperative complications (p < 0.01) at a cut-off value of 41.9% with a sensitivity of 60.0% and specificity of 67.7%. Conclusions Postoperative CRP levels in patients with intestinal BD undergoing surgical resection were associated with postoperative outcomes.
