BackgroundNonsteroidal anti-inflammatory drugs (NSAIDs) have been linked recently to a lower expression of pro-inflammatory cytokines in humans with acute pancreatitis. Because it is unclear if this effect results in clinical benefits, the aim of this study was to determine if prior NSAID exposure improves immediate clinical outcomes.MethodsRetrospective medical record review of adult patients admitted with acute pancreatitis. Cases were extracted from a national Veterans Affairs database using International Classification of Diseases, Ninth Revision codes. Prior NSAIDs use was determined through pharmacy data claims. The rates of acute kidney injury, respiratory failure, cardiovascular failure, and in-hospital mortality were compared between those with prior NSAID use (AP+NSAID) and those without it (AP-NSAID) using univariate and multivariate analysis.ResultsA total of 31,340 patients were identified: 28,364 AP+NSAID and 2976 AP-NSAID. The median age was 60 years, 68% were white, and the median hospital stay was 4 days. Approximately 2% of patients died during the hospitalization. After adjusting for demographics and other covariates, patients in the AP+NSAID arm had lower rates of acute kidney injury, P = .0002), cardiovascular failure (P = .025), any organ failure (P ≤ .0001), and in-hospital mortality (P < .0001).ConclusionPrior use of NSAIDs is associated with a lower incidence of organ failure and in-hospital mortality in adult patients with acute pancreatitis. The role of NSAIDs as therapeutic agents in this condition should be evaluated in interventional trials.Copyright © 2021 Elsevier Inc. All rights reserved.
