Inflammatory cytokines, C reactive protein, and procalcitonin as early predictors of necrosis infection in acute necrotizing pancreatitis.

Background: Infection of necrosis is a major risk factor in patients with acute pancreatitis. Systematic use of broad spectrum antibiotics has been recommended in these patients but may induce serious side effects. To better target patients in whom antibiotic prophylaxis could be beneficial, we evaluated whether early serum profiles of interleukin 6 (IL-6), tumor necrosis factor (TNF-alpha, C reactive protein (CRP) and procalcitonin (PCT) help to discriminate between patients who eventually develop infection of necrosis and those who do not.
