Computed tomography versus Acute Physiology and Chronic Health Evaluation II score in predicting severity of acute pancreatitis: a prospective, comparative study with statistical evaluation.
ABSTRACT The aim of the study was to compare Acute Physiology and Chronic Health Evaluation II score and C-reactive protein as a clinical index and computed tomography-based severity index (CTSI) in predicting the course of acute pancreatitis.
One hundred forty-eight patients with acute pancreatitis were enrolled in the study during a 2-year period. All data concerning etiology, Atlanta classification, CT findings, Acute Physiology and Chronic Health Evaluation score, C-reactive protein levels, stay in the intensive care unit, length of hospital stay, treatment, complications, and deaths were analyzed with Mann-Whitney U, Wilcoxon, Pearson, and Spearman statistical tests. The CT was performed on a spiral unit after intravenous administration of contrast material. Images were graded according to the Balthazar-CTSI scoring system.
A very good correlation was noticed between Balthazar-CTSI scores and local complications, whereas no statistically significant correlation was found between CT scores and stay in the intensive care unit. Among survivors and nonsurvivors, there were no statistically significant differences as far as CT scores were concerned.
Although the extent of necrosis as defined on contrast-enhanced CT examinations is considered as a risk factor for a negative prognosis, our findings suggest that the initially documented disease severity according only to imaging parameters is not highly important for the final patient outcome.

ABSTRACT: Severity scores are used to predict the outcome of acute pancreatitis (AP). Several scores are used in adult patients, but none has been thoroughly validated for specific use in paediatric patients. We retrospectively collected data from 48 children with AP (13 severe and 35 mild). The main causes were trauma (23%), idiopathic (23%), lithiasis (12.5%), and virus (10.5%). We evaluated 3 clinical scores (Ranson, Glasgow modified, and DeBanto) and Balthazar computed tomography severity index. The clinical scores had a good specificity (approximately 85%) but a low sensitivity (approximately 55%) in predicting the severity of paediatric AP. The radiological score is better (sensitivity 80%, specificity 86%). The area under the receiver operator characteristic curve was 0.699 (95% CI 0.508%-0.891%, P = 0.054) for the DeBanto score, 0.846 (95% CI 0.69%-1%, P = 0.001) for the Ranson score, and 0.774 (95% CI 0.584%-0.964%, P = 0.008) for the Glasgow and 0.898 (95% CI 0.73%-1%, P = 0.011) for the Balthazar computed tomography severity index score. In our paediatric cohort, the severity of AP was best predicted by Balthazar computed tomography-based scoring scale. Our results confirm previously reported low sensitivity of adult-based clinical scoring scales.Journal of pediatric gastroenterology and nutrition 03/2012; 55(3):266-7. · 2.18 Impact Factor

ABSTRACT: . Early assessment of severity in acute pancreatitis (AP) is a key measure to provide rational and effective management. The aim of our study is to determine the prognostic value of interleukins (IL) 6, 8, and 10, soluble receptor for tumor necrosis factor (sTNFr), pancreatic elastase (E1), and C-reactive protein (CRP) as predictors of systemic complications in AP. . A hundred and fifty patients with confirmed AP were enrolled in the study. The severity of AP was defined according to Atlanta criteria. Measurements of interleukins and sTNFr were performed on the first day of admission. CRP and E1 levels were assessed on admission and after 48 hours. ROC analysis was performed for all parameters. . Interleukins and sTNFr significantly differentiated patients with systemic complications from those without. Elevation of IL-6 showed the highest significance as a predictor ( = 0.001). CRP and elastase levels did not differ between mild and severe cases on admission, but reached statistical significance when measured on the third day ( = 0.002 and = 0.001, resp.). . Our study confirmed that IL-6, IL-8, IL-10, and sTNFr measured on admission, and CRP and pancreatic elastase measured on third day of admission represent valuable prognostic factors of severity and systemic complications of AP.Gastroenterology Research and Practice 01/2013; 2013:282645. · 1.62 Impact Factor
