Background and study aimsInfliximab (IFX) is a chimeric anti-TNF-α body which is effectively used in the treatment of inflammatory bowel diseases and a variety of autoimmune diseases. The effect of IFX on the healing of intestinal anastomosis has been evaluated in several studies, however with conflicting results. Furthermore, the effect of IFX on colonic anastomosis in sepsis has not been evaluated to date. In this study, we aimed to investigate whether IFX has an adverse effect on the healing process of colonic anastomosis either under normal or septic condition.Material and methodThe efficiency of IFX was assessed with respect to anastomotic bursting pressure (ABP), tissue hydroxyproline levels (THL) and histopathological examination of left colonic anastomosis in 40 male rats. The rats were randomly allocated into four groups of 10 rats each as control (C), septic control (SC), control IFX (C-IFX) and septic IFX (S-IFX).ResultsThe anastomotic bursting pressure was measured at 182±19.1, 158±15.4, 161±26.8 and 100±10.3mm/Hg, in C, SC, C-IFX and S-IFX; respectively. IFX administration did not influence the anastomotic strength under normal condition whereas in sepsis significantly induced the reduction of APB. The mean THL was almost similar in both control groups (p=0.87), whilst IFX reduced the level of TH in sepsis comparing with control groups (p=0.01). IFX significantly impaired immune response in sepsis resulting in poor anastomotic healing in S-IFX group.ConclusionOur study demonstrated that IFX had no detrimental effect on the healing of colonic anastomosis under normal condition whilst significantly impaired the healing process in sepsis.
