The neutrophil-lymphocyte ratio as a predictor of steroid response in patients with severe ulcerative colitis: a retrospective cohort study
REVISTA ESPANOLA DE ENFERMEDADES DIGESTIVAS(2023)
摘要
In this study we assessed the neutrophil-lymphocyte ratio (NLR) as a predictor of steroid non-response (SNR) in patients with acute severe ulcerative colitis and found a NLR on day 3 (NLR-3) >6.1 as a suitable cutoff point to identify SNR (OR 3.44, 95%CI 1.22-9.66) with sensitivity, specificity, positive predictive value, negative predictive value, and AUROC of 66.75, 63.2%, 35.9%, 86%, and 0.650, respectively. A model including bowel movements, albumin levels, and a NLR-3>6.1 had an AUC of 0.812 to predict SNR, with acceptable calibration.
