Use of antibiotics in acute pancreatitis: ten major concerns

Abstract

Acute pancreatitis is one of the most common gastrointestinal causes for hospitalization. In 15–20% it evolves into severe necrotizing pancreatitis. Recent studies have shown no association between the initiation of antibiotic therapy in acute pancreatitis and severe outcomes such as organ failure, infection of pancreatic necrosis, extrapancreatic infections or mortality. Specific subgroups with predicted severe acute pancreatitis or both extensive sterile necrosis and persistent organ failure may benefit from prophylactic antibiotics. Local infection develops in 30% of patients with pancreatic necrosis and results in morbidity and mortality. Contrast enhanced computed tomography should be performed in all patients with acute pancreatitis who develop sepsis, organ failure or fail to improve. C-reactive protein is an independent predictor of severe acute pancreatitis. Procalcitonin is the most sensitive laboratory test for detection of pancreatic infection. Antibiotics do however play a large role in patients with suspected or confirmed infected pancreatic necrosis and extrapancreatic infections. In clinical practice most clinicians prescribe antibiotics in the first 3?days of acute pancreatitis which in turns lead to excessive, unjustified use of antibiotics. Deep knowledge of the recent guidelines combined with an individualized management based on right clinical judgment is a rationale approach of patients with acute pancreatitis.
