Circulating polymorphonuclear leukocytes (PMNLs) may contribute to development of organ dysfunction in acute pancreatitis (AP). We outlined aberrations in PMNL signaling profiles in patients with AP complicated by organ dysfunction and immune suppression. ⋯ In patients with AP complicated by organ dysfunction proportion of pNFκB-positive PMNLs is decreased. This impairs patients' defense mechanisms against infection. Despite immune suppression, PMNL transmigration was increased and p38 phosphorylation capacity was not depressed, which may contribute to end organ inflammation and dysfunction.
