A preoperative low nutritional prognostic index correlates with the incidence of incisional surgical site infections after bowel resection in patients with Crohn’s disease

Abstract Aim Bowel resection in Crohn's disease still has a high rate of complications due to risk factors including immune suppression, malnutrition and active inflammation or infection at the time of operating. In this study, we use serological levels and inflammatory markers to predict the potential of complications in patients undergoing resections for complicated Crohn's disease. Methods All patients undergoing laparoscopic bowel resection for Crohn’s disease from 5th of November 2012 to 11th of October 2017 were included in this retrospective observational study. Patients were divided into 4 groups scoring 0, 1, 2 or 3 depending on their pre-operative haemoglobin concentration (Hb), C-reactive protein (CRP) and albumin (Alb) where 1 point was given for an abnormal value in each as detailed in the definitions. They were then grouped into a low risk group comprised of those scoring 0 and 1, and a high risk group for those scoring 2 and 3 and data was collected to compare outcomes and the incidence of septic complications. Results Seventy-nine patients were included. Eleven (13.9%) and 2 (2.5%) patients had 2 or 3 abnormal values of CRP, Alb and Hb and were categorized as high risk. High risk patients had a significantly higher rate of post-operative septic complications (30.7%) compared with low risk patients (10.6%) p value < 0.0001. Conclusion Pre-operative CRP, haemoglobin and albumin can serve as predictors of septic complications after surgery for Crohn’s disease and can therefore be used to guide pre-operative optimisation and clinical decision-making.

Abstract Background The aims of this study were to characterize the immune response profile in patients with Crohn’s disease (CD) and early postoperative recurrence (POR), to identify predictive biomarkers, and to develop a noninvasive predictive tool for individual estimation of POR risk. Methods Sixty-one patients who had undergone ileocolonic resection for CD were prospectively included and followed up for 24 months. Fecal calprotectin (FC), analytical parameters, and plasma cytokines were obtained before surgery and at various time points during postoperative follow-up. Morphological recurrence was assessed by ileocolonoscopy or magnetic resonance enterography within 6–12 months after surgery. Clinical activity was scored using the Harvey-Bradshaw Index. Results Twenty-seven patients (44.3%) had morphological recurrence during follow-up. Fecal calprotectin values were significantly associated with POR risk over time. The receiver operating characteristic curve for FC provided an area under the curve (AUC) of 0.88 (95% confidence interval, 0.75–0.96), and morphological recurrence was best predicted by FC ≥160 μg/g at 6 months after surgery (85% sensitivity, 70% specificity, 26% predictive positive value, 98% negative predictive value [NPV]). The plasma cytokine profile showed higher presurgery interleukin (IL)-13 plasma levels and higher IL-6 and interferon (IFN)-γ levels at 6 months after surgery in patients with POR compared with patients without recurrence. The combination of FC, IL-6, and IFN-γ values at 6 months gave an AUC of 0.90 for predicting an early recurrence. Conclusions FC values <160 μg/g at 6 months have a high NPV to rule out early lesions. Combined values of FC, IL-6, and IFN-γ levels at 6 months postsurgery constitute a prognostic index with a high predictive capacity to assess the risk of early POR.
