AB BACKGROUND & AIMS: The role of the cytokine interleukin 2 (IL-2) has
long been recognized as central to normal immunologic function and
defense against infection after burns and trauma, but little effort has
been directed towards its role in acute pancreatitis (AP), which also
has a high mortality related to sepsis. This study investigated the
potential role of IL-2 in mice with diet-induced AP. METHODS: AP was
induced in mice by 10 days of feeding a choline-deficient,
ethionine-supplemented diet. T-helper (CD4) cells were estimated, and
T-cell mitogen-stimulated splenocyte proliferation and IL-2 production
in vitro were measured on days 3, 7, and 10. RESULTS: Significant
reduction in IL-2 production was found on day 3 (32%; P < 0.05) and day
10 (48%; P < 0.005). Administration of intraperitoneal
lipopolysaccharide on day 10 was associated with reduced IL-2 production
(P < 0.025) 4 hours later and 90% mortality in animals with AP. In vivo
therapy with recombinant IL-2 improved in vitro IL-2 secretion (P <
0.05) and reduced lipopolysaccharide-induced mortality (P = 0.036).
CONCLUSIONS: Murine diet-induced AP is associated with impaired immune
function and increased susceptibility to sepsis and may be a valuable
tool in the investigation of immunomodulation in AP.
