BACKGROUND: Mycophenolate mofetil (MMF) or enteric-coated mycophenolate sodium (MPS) are now commonly used in pediatric intestinal transplantation (Tx), but to date, no clear recommendations regarding the dosing regimen have been made in this population. The aim of this study was to determine the MMF/MPS dosage required to achieve an area under the plasma concentration-time curve from 0 to 12 hours (AUC0-12) for mycophenolic acid (MPA) greater than 30 mg.h/L in children after intestinal transplantation...

AIM: Our aim is to describe our achievements in pediatric intestinal transplantation (ITx) and define areas for improvement. METHODS: After a period (1987-90) of 9 isolated small bowel transplants (SBTx) where only one patient survived with her graft, 110 ITx were performed on 101 children from 1994 to 2014: 60 SBTx, 45 liver-small bowel, 4 multivisceral (3 with kidneys), 1 modified multivisceral. Indications were short bowel syndrome (36), motility disorders (30), congenital enteropathies (34) and others (1)...

The main cause of acute intestinal failure is short bowel syndrome, generally as a result of resection of extensive segments of small intestine. As a result, the main symptoms are watery diarrhea, malabsorption syndrome, chronic malnutrition, and death, if the patient is not properly treated. If the length of the remaining intestine is greater than 30 cm, complete adaptation is possible and the patient may not require parenteral nutrition. The currently recommended treatment includes the use of prolonged parenteral nutrition and enteral nutrition, always aimed at constant weight gain, in conjunction with surgeries aimed at elongating the dilated bowel...

Intestinal failure is a serious complication of conditions such as inflammatory bowel disease, mesenteric ischemia, and radiation enteritis--and of extensive bowel resection performed because of these diseases. Imbalances of fluids and electrolytes and poor nutritional status manifest as chronic diarrhea or increased ostomy output. Prompt referral to a center specializing in intestinal rehabilitation is key to achieving nutritional homeostasis and, in some cases, can help the patient return to oral food intake...

Ileoscopy with mucosal biopsy is fundamental in the management and surveillance of inflammatory bowel disease patients and intestinal transplant recipients. There is a paucity of data describing the risks of ileoscopy in the presence of a prolapsed stoma. Parastomal hernias are frequently associated with prolapsed stomas. We report the first case of perforation during ileoscopy in the setting of a prolapsed stoma and unrecognized parastomal hernia. Recognition of parastomal hernia associated with stoma prolapse is of paramount importance in patients undergoing ileoscopy as it may increase the risk of perforation...

Children with intestinal failure have had improved survival, particularly those with extreme short bowel syndrome, over the last 10-15 y. This has been attributed to better understanding of the pathophysiology of intestinal failure, improvement in line care, recognition of the importance of a team approach as well as the progress of intestinal transplant as a viable option. Parenteral nutrition remains the cornerstone for the continual survival of these patients. This review will cover contemporary approaches to intestinal failure including post surgical approaches, non-transplant surgery, dietetic and medication approaches during the adaptation process, considerations for home parenteral nutrition and latest in intestinal transplantation...

Antibody-mediated rejection (ABMR) has increasingly emerged as an important cause of allograft loss after intestinal transplantation (ITx). Compelling evidence indicates that donor-specific antibodies can mediate and promote acute and chronic rejection after ITx. However, diagnostic criteria for ABMR after ITx have not been established yet and the mechanisms of antibody-mediated graft injury are not well-known. Effective approaches to prevent and treat ABMR are required to improve long-term outcomes of intestine recipients...

Intestinal transplantation is the most immunologically complex of all abdominal organ transplants. Understanding the role both humoral and innate and adaptive cellular immunity play in intestinal transplantation is critical to improving outcomes and increasing indications for patients suffering from intestinal failure. Recent findings highlighting the impact of donor-specific antibodies on intestinal allografts, the role of NOD2 as a key regulator of intestinal immunity, the protective effects of innate lymphoid cells, and the role of Th17 in acute cellular rejection are reviewed here...

BACKGROUND: The pathology and diagnosis of acute and chronic rejection in intestinal transplantation are far from being completely understood. We established models of acute and chronic intestinal graft rejection and analysed peripheral and intragraft immune responses. METHODS: We performed intestinal transplantation (ITX) from Dark Agouti into Lewis rats applying single-dose tacrolimus (TAC) at varying concentrations. Graft histology and immunohistology were assessed on POD7,14,45...

BACKGROUND: Intestinal transplant recipients require frequent hospital readmission after a successful transplantation, but the reasons for readmission have not been characterized in detail. METHODS: We reviewed our single-center experience to characterize the patterns of readmissions and to identify preventable causes. Among 87 adult patients who received an intestinal or multivisceral transplant, 65 patients (35 males, 30 females; median age, 42 years [range, 19-66]) with a follow-up of at least 1 year were included in this study...

BACKGROUND: Non-HLA-allo- and autoantibodies are involved in allograft rejection in kidney and heart transplantation. Their role in intestinal transplantation has not yet been described. We examined the development of anti-Angiotensin II type I receptor antibodies (anti-AT1R) and anti-Endothelin-Type A receptor antibodies (anti-ETAR) associated with the clinical course and histopathological findings of ITX-recipients. METHODS: 37 patients underwent intestinal or multivisceral transplantation...

BACKGROUND: Rejection remains the leading cause of allograft loss, and a major barrier to improving long-term outcomes following intestinal transplantation (ITx). 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. Patients were screened for DSA pretransplant, monitored regularly posttransplant and when clinically-indicated using the single-antigen bead Luminex assay...

BACKGROUND: The long-term outcome of intestinal transplantations is still not favorable, which is partly due to the intestinal susceptibility to ischemia. There are several indications that the inflammatory response to ischemia-reperfusion injury is mediated by cyclooxygenases and that their inhibition may be associated with improved organ function. The aim of this study was to analyze if COX inhibitors could improve the early posttransplant outcome after orthotopic small bowel transplantation (SBTx)...

Intestinal transplantation (ITx) is often associated with decreased abdominal domain, rendering abdominal closure difficult. Pre-transplant placement of tissue expanders (TE) can overcome this challenge; however it can be associated with life-threatening complications. This review aimed to comprehensively summarize all available literature on TE in ITx candidates and include the technical details of osmotic, self-inflatable TE -a technique undescribed before. PubMed, EMBASE and CCTR were searched until April 30, 2016...

BACKGROUND: Microvillus inclusion disease (MVID) is a known congenital cause of intractable diarrhea resulting in permanent intestinal failure. There is need for a lifelong total parenteral nutrition (TPN) from diagnosis and the prognosis is poor. Most patients die by the second decade of life as a result of complications of parenteral alimentation including liver failure or sepsis. The only available treatment at this moment is a small bowel transplantation. But before that moment, the patients often suffer from a persistent failure to thrive and electrolyte disturbances despite continuous TPN...

INTRODUCTION: Megacystis microcolon intestinal hypoperistalsis (MMIHS) is a rare disorder characterized by distended nonobstructed bladder, microcolon, and decreased intestinal peristalsis. MMIHS has a particularly poor prognosis; however, when appropriately managed, survival can be prolonged. STUDY DESIGN: A systematic review (1996-2016) was performed with the key words "megacystis microcolon intestinal hypoperistalsis syndrome." In addition, a case series of four patients is presented as well as algorithms for the diagnosis and treatment of MMIHS...
