- Ileocaecal resection for Crohn's disease is commonly performed. The severity of endoscopic lesions in the anastomotic area one year postoperatively is considered to reflect the subsequent clinical course. Fecal calprotectin (FC) has been shown to correlate with the findings at ileocolonoscopy in Crohn's disease. The objectives of this study were to assess whether the concentration of FC reflects the endoscopic findings one year after ileocaecal resection and to evaluate the variation of FC in individual patients during 6months prior to the ileocolonoscopy.

- Background Although infliximab treatment is an option for patients with ulcerative colitis (UC), not all patients do respond to therapy, and cellular mechanisms leading to therapy response are incompletely known. Objective The objective of this article is to determine early effects of infliximab therapy on T cells in the blood of UC patients and if effects differed in therapy responders and nonresponders. Methods: Blood samples were obtained before and two weeks post-treatment start from 34 anti-tumor necrosis factor (TNF) therapy-naïve UC patients undergoing infliximab therapy. Response to therapy was evaluated prior to the fourth treatment dose. Expression of T cell surface markers and levels of soluble receptors and cytokines in serum were determined. Results At baseline, there were no differences in cellular, biochemical or clinical parameters between therapy responders and nonresponders. Infliximab therapy reduced frequencies of CD25+ T cells and increased frequencies of annexin V+ T cells in patients responding to infliximab, but not in nonresponding patients, two weeks after therapy start. Only therapy responders had decreased serum levels of sCD25 and sTNFRII two weeks after treatment start. In contrast, clinical parameters did not reflect therapy outcome already two weeks after therapy start. Conclusion Soluble and membrane-bound T cell receptors may be early indicators of infliximab therapy response in UC, which can be of clinical importance for the decision when to continue or to stop the treatment.

- Abstract Background. Self-expandable metallic stents (SEMS) placement is a standard treatment for inoperable malignant bile duct strictures. Covered SEMS have been introduced to avoid stent occlusion by tumor ingrowth. The aims were to compare covered and uncovered stents in terms of patency, efficacy and complication rate. Material and methods. Consecutive patients with inoperable malignant distal biliary strictures were included in the study and randomized to receive a covered (n = 34) or uncovered (n = 34) Hanaro SEMS. Follow-up was performed by nurses after 18 h, 48 h, 2 weeks and thereafter every month until stent dysfunction or the patient died. Outcomes were measured as follows: the patients reported urine and stool color, presence of fever and abdominal pain. Liver function tests and CRP were analyzed each time. The procedure time and complications were monitored. The follow-up was blinded to stent type. Results. The median patient age was 79 years (IQR: 66-83, R: 54-92), 59% were female and 85% had the gallbladder in situ. There was no difference between covered and uncovered stents in terms of procedure time (median: 30 min (20-38, R: 12-90) vs. 30 min (IQR: 20-42, R: 12-70)), stent patency (median: 153 days (IQR: 65-217; R: 20-609) vs. median of 127 days (IQR: 70-196; R: 18-486)) or patient survival (median: 154 days (IQR: 65-217; R: 21-609) vs 157 days (IQR: 70-273, R: 20-690)). Eighty-seven percent died with a patent covered and 83% with an uncovered stent (n.s.). Two early complications occurred (sepsis; pancreatitis), both with covered stents. Conclusion. There is no clinical difference between covered and uncovered biliary Hanaro SEMS. Both types are easily inserted with low complication rate and have long-term patency.
