Intestinal Re-Transplantation.

The history of intestinal transplantation can be traced back to the turn of the twentieth century. Although advancements have been made, the intestine still presents a greater challenge to transplantation than does that of other solid organs, experiencing higher rates of graft rejection and lower long-term survival. Increasingly, intestinal re-transplantation (re-ITx) is seen as a viable option and is now the fourth most common indication for ITx.

Non-HLA AT1R antibodies are highly prevalent after pediatric intestinal transplantation.

The role of angiotensin II type-1 receptor (AT1R) antibodies in intestinal transplantation (ITx) is unclear. The aims were 1) to identify the prevalence of AT1R antibodies in pediatric ITx, compared to pediatric intestinal failure (IF), and 2) to determine whether AT1R antibodies were associated with graft dysfunction. 46 serum samples from 25 ITx patients (3 isolated ITx, 22 liver-inclusive ITx) were collected during routine visits >6 months apart and during episodes of graft dysfunction as a result of infectious enteritis or rejection.

Characterization of T cell immunophenotypes in intestinal transplantation: A pilot study.

Immunophenotyping of peripheral blood mononuclear cells has been shown to be a useful, non-invasive method of predicting acute cellular rejection (ACR) following intestinal transplantation (ITx). Our objectives were to characterize differences in the T cell immunophenotype of ITx recipients in peripheral blood samples (1) collected late versus early after ITx and (1) associated with episodes of ACR and infectious enteritis. An IRB-approved, cross-sectional study of ITx recipients was performed.

Prevalence and Clinical Impact of Donor-Specific Alloantibody Among Intestinal Transplant Recipients.

Background: Rejection remains the leading cause of allograft loss, and a major barrier to improving long-term outcomes after intestinal transplantation. Our aim is to define the prevalence and investigate the role of donor-specific antibody (DSA) on intestinal graft outcomes.

Methods: The study includes 109 transplants performed in 95 recipients at a single center.

Incidence, timing, and significance of early hypogammaglobulinemia after intestinal transplantation.

Background: Despite recent advances in intestinal transplantation (ITx), infection (INF) and acute cellular rejection (ACR) remain major causes of patient and graft loss. Studies in other solid-organ transplantations indicate that low levels of serum immunoglobulin G (IgG) negatively impact outcomes. To date, there have been no studies on IgG after ITx.

Pretransplant predictors of survival after intestinal transplantation: analysis of a single-center experience of more than 100 transplants.

Introduction: Outcomes after intestinal transplantation (ITx) have steadily improved. There are few studies that assess factors associated with these enhanced results. The purpose of this study was to examine peri-ITx variables and survival.

Immunosuppression and the risk of post-transplant malignancy among cadaveric first kidney transplant recipients.

The success of renal transplantation may be counterbalanced by serious adverse medical events. The effect of immunosuppression on the incidence of de novo neoplasms among kidney recipients should be monitored continuously. Using data from the Scientific Registry of Transplant Recipients, we studied the association of induction therapy by immunosuppression with antilymphocyte antibodies, with the development of de novo neoplasms.

One hundred in situ split-liver transplantations: a single-center experience.

Objective: To identify predictors of graft and recipient survival from a single-institution series of in situ split-liver transplantations and compare outcomes to living donor and whole organs for adults and children.

Summary Background Data: Split-liver transplantation is a surgical technique that creates 2 allografts from a single cadaver donor. We have applied split-liver transplantation to all indications and categories of medical urgency for initial as well as retransplantation to expand the current donor pool and decrease reliance upon living donation.

Liver transplantation for fulminant hepatic failure: experience with more than 200 patients over a 17-year period.

Objective: To analyze outcomes after liver transplantation (LT) in patients with fulminant hepatic failure (FHF) with emphasis on pretransplant variables that can potentially help predict posttransplant outcome.

Summary Background Data: FHF is a formidable clinical problem associated with a high mortality rate. While LT is the treatment of choice for irreversible FHF, few investigations have examined pretransplant variables that can potentially predict outcome after LT.
