Abstract
BACKGROUND Graft loss in intestinal transplantation (ITx) is close to 25% in the first year and 50% at 5-year post-transplantation. Although technically and immunologically challenging, intestinal retransplantation is now the 4th most common indication for ITx. METHODS The aim of this study was to review and compare the outcomes of intestinal retransplantation with primary ITx, which included isolated ITx, modified multivisceral transplantation (mMVTx), and full MVTx, between 2003 and 2014 at Indiana University. RESULTS Of 218 ITx, 18 (8.3%) were retransplantation. Causes of graft loss were rejection(78%), pancreatitis (11%), and severe intestine dismotility (11%). MVTx (16/18, 89%) was the preferred retransplantation option. In 7 (39%) patients, graftectomy was performed between primary and intestinal retransplantation. Median interval between primary ITx and retransplantation was 421 days. Although patient and graft survival rates at 1 year, 3 years, and 5 years were comparable between primary and retransplants, the number of retransplants was limited in the follow-up after post-transplant year 3. CONCLUSIONS We identified that timing of retransplantation, graftectomy prior to retransplant allowing an immunosuppression free state, inclusion of the liver, and preserved renal function are important factors in the consideration of intestinal retransplantation. Immunological aspects remain challenging in the decision making and for short- and long-term outcomes.

Abstract
BACKGROUND We evaluated the outcomes of intestinal retransplantation in children and adults in the United States. METHODS The United Network for Organ Sharing data were analyzed from October 1987 to August 2009. RESULTS In adult isolated intestinal transplant (ITx) retransplants (n=41), patient survival was 80.1%, 47.4%, and 28.5% at 1, 3, and 5 years, which was worse than primary isolated ITx (P=0.005). For liver ITx (L-ITx) retransplants (n=31), patient survival was 63.1%, 56.1%, and 46.8% and was not significantly different than primary L-ITx. In pediatric isolated ITx retransplants (n=28), patient survival at 1, 3, and 5 years was 80.7%, 74%, and 57.5%; graft survival was 76.4%, 56.6%, and 44%. In L-ITx retransplants (n=49), patient survival was 42%, 42%, and 42%; graft survival was 39%, 39%, and 39%. Patient and graft survival in adult L-ITx retransplants were better in era 2 (January 2001-August 2009) than era 1 (October 1987-December 2000) (P=0.01). Among pediatric L-ITx retransplants, outcomes were worst in children younger than 2 years (n=12). In regression analysis, prior hospitalization was a negative predictor for all the groups of patients (relative risk, 5.4). CONCLUSION Patient and graft survival in adult isolated ITx are less favorable after a retransplant compared with a primary transplant. Patient and graft survival are also poor in pediatric L-ITx after a retransplant, especially for children younger than 2 years of age. L-ITx retransplant results improved significantly in era 2 in adult recipients.

Abstract
OBJECTIVES To examine changes in individual bile acids in serum in a pig model of allogenic small bowel transplantation. METHODS Seventeen pigs were divided into two groups: group 1 (n=10), controls; group 2 (n=7), allotransplantation, nonimmunosuppressed recipients. Both groups received a segmental intestine. Intestinal specimens for histologic studies were obtained at the end of cold flushing (T0) and on postoperative day 8 (T1). Total and individual bile acid concentrations were measured in serum samples taken at T0 and T1. RESULTS All animals survived until the end of the study. In group 1, intestinal histology revealed no significant changes between T0 and T1 specimens. In contrast, in group 2, graft histology revealed moderate to severe rejection at T1 in all specimens. In contrast to group 1, serum levels of total bile acids increased significantly in group 2 at T1 compared with baseline (P=0.001). The increase was due to secondary bile acids which were significantly higher at T1 compared with baseline (P=0.0003). In contrast, secondary bile acids increased but not significantly at T1 in group 1 compared with baseline (P=0.056). CONCLUSION Our study suggests that total and secondary serum bile acids may be a useful diagnostic tool for the diagnosis of acute intestinal rejection.

Abstract
Even though surgical techniques for isolated intestine, liver-intestine, and multivisceral transplantations were developed in the 1960's, very few patients were transplanted before 1990 because initial immunosuppression regimens were insufficient, making intestine transplantation impossible. Intestine transplantation resulted in death in most patients within days or months. The discouraging results of the first clinical trials were due to technical complications, sepsis, and the failure of conventional immunosuppression to control rejection. By 1990 the development of tacrolimus-based immunosuppression and improved surgical techniques, the increased array of potent immunosuppressive medications, infection prophylaxis, and suitable patient selection helped improve actuarial graft and patient survival rates for all types of intestine transplantation. The aims of this review are to describe the current status of intestine transplantation including the underlying diseases and conditions that may be indications for intestine transplantation, to identify patient populations for this indication, to provide key steps for patient evaluation, to summarize current recommendations for immunosuppression, to list the most common postoperative complications, and to discuss the international experience of small bowel transplantation compiled and analyzed by the International Intestine Transplant Registry since 1985.

Abstract
BACKGROUND Because no biomarker that reflects small bowel allograft rejection is available, we applied surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) to develop noninvasive markers required for routine diagnosis. METHODS Heterotopic small bowel transplantation (SBT) was performed in rats, and they were divided into four experimental groups: sham-operated rats (sham), syngeneic transplants (syngeneic), allogeneic transplants (allogeneic), allogeneic transplants received FK506 (allo+FK). Plasma samples were analyzed with SELDI ProteinChip arrays to detect peaks that predominated in the allogeneic model. Possible biomarkers were identified in combination with SELDI retentate chromatography mass spectrometry (RCMS) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). The identified protein was further analyzed by immunohistochemistry. RESULTS An increase in the level of a 14.8-kDa protein, identified as lysozyme, was observed specifically in the plasma of the allogeneic group; the levels of this protein remained unchanged in the plasma of the other groups. On the other hand, the levels of a 10.1-kDa and a 13.0-kDa protein, identified as migration inhibitory factor-related proteins (MRP), MRP-8 and MRP-14, respectively, began to increase from an early stage of acute rejection. We also observed that lysozyme-positive macrophages had strongly infiltrated the lamina propria during acute rejection. CONCLUSIONS We identified three plasma proteins-MRP-8, MRP-14, and lysozyme-that increased during small bowel allograft rejection. The identified proteins appeared to be markers for inflammation associated with allograft rejection. This proteomic approach will be useful for the identification of candidate biomarkers.

Abstract
BACKGROUND The small bowel has been successfully transplanted in patients with irreversible intestinal failure. This report aims to describe endoscopic monitoring of small bowel rejection. METHODS A magnification endoscope (zoom endoscope) was used in this study. In the first part of the study (October 1998 to March 2000, 271 endoscopy sessions), the specific endoscopic findings that correlated with rejection were determined. An analysis then was performed on data from the second period (March 2001 to November 2002, 499 sessions) to evaluate the zoom endoscope's accuracy in monitoring rejection. RESULTS Specific endoscopic findings of rejection found in the first period included background erythema, villous congestion, blunted villous tip, and shortened villous height. When the rejection was successfully treated, endoscopic appearance returned to normal. On the basis of these findings, five endoscopic criteria (villous shortening, villous blunting, background erythema, villous congestion, and mucosal friability) were used to score endoscopic sessions in the second period. Endoscopic diagnosis of rejection was compared with histology. Adult patients showed a sensitivity of 45%, a specificity of 98%, a positive predictive value of 82%, and a negative predictive value of 88%. In pediatric patients, these values were, respectively, 61%, 84%, 57%, and 86%. On 59 distinct occasions (30 in period 1 and 29 in period 2) in which the results were endoscopy negative yet biopsy positive (mild) for rejection, we elected not to treat these rejections on the basis of clinical evaluation, and 58 (98%) resolved without further therapy. CONCLUSIONS With the use of magnification, endoscopy is a useful tool for monitoring acute rejection in the small bowel allograft.

Abstract
We performed 124 intestinal transplants on 108 children (median age, 1.5 years) since 1994. Initial graft types included isolated intestine (I) (n=26), liver and intestine (LI) (n=26), multivisceral (MV) (n=50), and multivisceral without liver (MMV) (n=6). Four groups were defined by type of induction therapy: none, OKT3, or cyclophosphamide (August 1994-December 1997, n=25), early experience with daclizumab (January 1998-December 2000, n=26), recent experience with daclizumab (January 2001-April 2004, n=40), and Campath-1H (January 2001-April 2004, n=17). Actuarial patient survival at 1 year for groups 1-4 was 44%+/-10%, 54%+/-10%, 83%+/-6%, and 41%+/-12%, respectively, with group 3 having the most favorable survival (P=0.0004). Using Cox stepwise regression, the hazard rate of developing severe rejection was significantly higher in patients with transplant type I or LI (P=0.0002), with no difference between these groups (P=0.24) but a significantly higher rate for LI versus MV (P=0.005). Three factors associated with improved patient survival were recipient of MV or MMV (P=0.008), age at transplantation greater than 1 year (P=0.01), and use of daclizumab (P=0.0006). Cause-specific hazard analysis revealed a decreased rate of rejection-related mortality for recipients of MV or MMV (P=0.0007), whereas age greater than 1 year indicated a lower rate of infection-related mortality (P=0.0009). Pediatric intestinal transplantation provides an increasingly realistic chance of survival, particularly with the more recent use of daclizumab and multivisceral transplantation. A protective effect of multivisceral transplantation appears to exist with respect to the development of severe rejection.
