The early identification of patients at risk for severe acute pancreatitis (SAP) is crucial. Serum markers of disease severity have been assessed including interleukin (IL)-6 and IL-8; however, their predictive accuracy has varied significantly across studies. We conducted a meta-analysis to assess the accuracy of IL-6 and IL-8 at predicting SAP.We identified relevant published articles and calculated pooled sensitivities, specificities and likelihood ratios using the random-effect model. We included values for days 1, 2 and 3 of presentation for IL-6 and for days 1 and 2 for IL-8. We also constructed summary receiver-operating curves and assessed the area under the curve (AUC) and the diagnostic odds ratios (DORs) as measures of diagnostic accuracy.For IL-6, we included 7 reports for day 1 and 4 reports for days 2 and 3. For IL-8, we analyzed 5 studies for day 1 and 4 for day 2. The pooled IL-6 sensitivities ranged between 81.0 and 83.6
