Taurolidine has potent antiendotoxin and antimicrobial effects in vitr
o. This study assessed the effect of taurolidine in a well-described m
odel of acute pancreatitis. Ninety-five male Wistar rats (250 g) were
studied. Pancreatitis was induced by intraductal injection of 50 mu l
of a 4% sodium taurocholate solution at a pressure of 25 cm water. Ani
mals were randomly allocated to 1 of 10 groups: 4 groups were used to
characterize the model and there were 6 treatment groups. Taurolidine
(100 mg/kg) or saline was administered intravenously at Time 1, 4 hr,
or 4 and 24 hr following induction of pancreatitis. Serum amylase, end
otoxin levels, and blood cultures were assessed at 4 and 24 hr. Surviv
al was documented at 1 week. Serum amylase levels were elevated in ani
mals in whom acute pancreatitis was induced; however, there was no dif
ference in serum amylase between animals treated with taurolidine and
those treated with saline. Positive blood cultures were more numerous
in saline-treated groups. Treatment with taurolidine was associated wi
th significantly (P < 0.01) lower endotoxin levels (14+/-8 pg/ml) comp
ared with saline-treated animals (350+/-87 pg/ml). Taurolidine adminis
tration significantly improved survival compared with controls, when g
iven at 4, 24, and 4/24 hr postinduction of pancreatitis (P < 0.05). T
aurolidine was beneficial in this model of acute pancreatitis. (C) 199
