    Combination of allopurinol and hyperbaric oxygen therapy
    (Pancreas, 2008) Cömert, Bilgin; Işık, Ahmet Turan; Aydın, Sezai; Bozoğlu, Ergun; Ünal, Bülent; Deveci, Salih; Mas, Nuket; Çınar, Eşref; Mas, Mehmet Refik
    AIM: To investigate the individual and combined effects of allopurinol and hyperbaric oxygen (HBO) therapy on biochemical and histopathological changes, oxidative stress, and bacterial translocation (BT) in the experimental rat acute pancreatitis (AP). METHODS: Eighty-five Sprague-Dawley rats were included in the study. Fifteen of the eighty-five rats were used as controls (sham, GroupⅠ). AP was induced via intraductal taurocholate infusion in the remaining seventy rats. Rats that survived to induction of acute necrotizing pancreatitis were randomized into four groups. Group Ⅱ received saline, Group Ⅲ allopurinol, Group Ⅳ allopurinol plus HBO and Group Ⅴ HBO alone. Serum amylase levels, oxidative stress parameters, BT and histopathologic scores were determined. RESULTS: Serum amylase levels were lower in Groups Ⅲ, Ⅳ and Ⅴ compared to Group Ⅱ (974 ± 110, 384 ± 40, 851 ± 56, and 1664 ± 234 U/L, respectively, P < 0.05, for all). Combining the two treatment optionsrevealed significantly lower median [25-75 percentiles] histopathological scores when compared to individual administrations (13 [12.5-15] in allopurinol group, 9.5 [7-11.75] in HBO group, and 6 [4.5-7.5] in combined group, P < 0.01). Oxidative stress markers were significantly better in all treatment groups compared to the controls. Bacterial translocation into the pancreas and mesenteric lymph nodes was lower in Groups Ⅲ, Ⅳ and Ⅴ compared to Group Ⅱ (54%, 23%, 50% vs 100% for translocation to pancreas, and 62%, 46%, 58% vs 100% for translocation to mesenteric lymph nodes, respectively, P < 0.05 for all). CONCLUSION: The present study confirms the benefit of HBO and allopurinol treatment when administered separately in experimental rat AP. Combination of these treatment options appears to prevent progression of pancreatic injury parameters more effectively.

    Effects of infliximab on bacterial translocation in experimental acute necrotizing pancreatitis
    (Wolters Kluwer Medknow Publications, 2012) Aydin, Sezai; Isik, A. Turan; Unal, Bulent; Comert, Bilgin; Ozyurt, Mustafa; Deveci, Salih; Ozgur, Gokhan
    Background & objectives: Translocation of bacteria from the gut is an important factor in the development of septic complications and mortality in acute pancreatitis (AP). The present study was designed to assess the effects of infliximab treatment on bacterial translocation (BT) in experimental acute necrotizing pancreatitis. Methods: Male Sprague-Dawley rats (n=45) were allocated into three groups. AP was induced in group II (positive control, n=15) and group III (Infliximab; n=15) by retrograde injection of taurocholate into the common biliopancreatic duct. Group I rats (Sham; n=15) received normal saline infusion into the common biliopancreatic duct as placebo. Groups I and II were treated by normal saline and group HI was treated with infliximab intraperitoneally on 6, 30 and 54 h after induction of pancreatitis. All surviving animals were killed 60 h after the induction of pancreatitis, and specimens were collected for amylase measurement as well as histopathologic and microbiologic examinations. Results: Oedema, acinar cell necrosis, inflammatory infiltration, haemorrhage, fat necrosis and perivascular inflammation in group III rats were decreased with infliximab treatment when compared with group II (P<0.001). BT to mesentery lymph node in groups I, II and III were 20, 100 and 46 per cent, respectively. BT to peritoneum and pancreas in group III was lower than group II (P<0.05). Interpretation & conclusions: Infliximab administration resulted in beneficial effects on BT and histopathologic changes in the experimental necrotizing pancreatitis. Whether anti-TNF therapy has a role in prevention of complications of ANP needs to be established.
