RESUMO
BACKGROUND/OBJECTIVES: Acute Pancreatitis (AP) is one of the leading gastrointestinal conditions requiring hospitalization. It has been suggested that statins could exert a protective role in the natural history of AP; however, their influence is not entirely clear. Our objective was to investigate the relationship between statin intake and AP. METHODS: Retrospective analysis of a prospective registry of patients diagnosed with AP. Statin intake on admission as well as clinical, analytical, demographic and radiological data were recorded. OUTCOME PARAMETERS: Severity of AP, SIRS development, organ failure, local complications, intensive care admission, collection drainage, hospital length of admission, and death. Univariate and multivariate analyses as well as a propensity score logistic regression were conducted. RESULTS: From March 2014-October 2018 we studied 356 patients. 101 patients (28%) were taking statins. 55 (15%) suffered from moderate/severe pancreatitis. Multivariate analysis showed a 50% less risk of suffering from moderate/severe AP (OR 0.50 95% CI 0.22-1.0, p 0.50) and 33% less risk of developing local complications (OR 0.33 95%CI 0.15-0.80, p 0.014) among statin consumers, with a tendency towards less SIRS. Propensity score analysis confirmed that patients on statins suffering from AP had a lower risk to have a moderate/severe episode (OR 0.409 95%CI 0.192-0.872, p 0.031), to develop local complications (OR 0.47 95%CI 0.20-1.06, p 0.11) and SIRS (OR 0.516 95% CI 0.28-0.93, p 0.041). CONCLUSIONS: Patients taking statins who suffer from an episode of AP are more likely to follow a mild course and have a lower risk of developing local complications and SIRS.
