Introduction: Translocation of bacteria from the gut is one of the most important factors in the development of septic complications and mortality in acute pancreatitis. Aims: To investigate whether S-methylisothiourea (SMT), taurine (TAU), and meropenem (MER) could effect bacterial translocation and the course of acute necrotizing pancreatitis. Methodology: Seventy male Sprague-Dawley rats were studied. Rats were randomly allocated into seven groups. Acute pancreatitis was induced in group II (MER), group III (TAU), group IV (TAU + MER), group V (TAU + SMT), group VI (TAU + MER + SMT), and group VII (positive control) by retrograde injection of taurocholate into the common biliopancreatic duct. Group I rats (sham) received normal saline infusion into the common biliopancreatic duct as negative control. Rats were treated with drug combinations intraperitoneally for 48 hours after induction of pancreatitis. At the 48th hour of induction, all animals were killed, and specimens were collected. Results: Bacterial translocation to peritoneum and pancreas in groups treated with MER were lower than in the other groups. Pancreatic tissue GSHpx and SOD levels were higher in all groups in comparison with levels in group VII. Pancreatic tissue MDA levels were also lower in all treatment groups except group II. The most favorable results were obtained in group VI (TAU + MER + SMT). Also, the lowest pathologic score between the groups in which acute pancreatitis developed was obtained in group VI. Conclusions: Addition of TAU and SMT to the treatment protocol for acute pancreatitis seems to improve the pathologic score and oxidative stress parameters. Also, antibiotherapy with MER decreases the risk of bacterial translocation.
