Long-Term Signs of T Cell and Myeloid Cell Activation After Intestinal Transplantation With Cellular Rejections Contributing to Further Increase of CD16 + Cell Subsets. Front Immunol 2019; 10:866.

Abstract
The intestine mediates a delicate balance between tolerogenic and inflammatory immune responses. The continuous pathogen encounter might also augment immune cell responses contributing to complications observed upon intestinal transplantation (ITx). We thus hypothesized that ITx patients show persistent signs of immune cell activation affecting both the adaptive and innate immune cell compartment. Information on the impact of intestinal grafts on immune cell composition, however, especially in the long-term is sparse. We here assessed activated and differentiated adaptive and innate immune subsets according to time, previous experience of cellular or antibody-mediated rejections or type of transplant after ITx applying multi-parametric flow cytometry, gene expression, serum cytokine and chemokine profiling. ITx patients showed an increase in CD16 expressing monocytes and myeloid dendritic cells (DCs) compared to healthy controls. This was even detectable in patients who were transplanted more than 10 years ago. Also, conventional CD4+ and CD8+ T cells showed persistent signs of activation counterbalanced by increased activated CCR4+ regulatory T cells. Patients with previous cellular rejections had even higher proportions of CD16+ monocytes and DCs, whereas transplanting higher donor mass with multi-visceral grafts was associated with increased T cell activation. The persistent inflammation and innate immune cell activation might contribute to unsatisfactory results after ITx.

Abstract
PURPOSE OF REVIEW This review summarizes the most recent relevant knowledge in clinical practice in the field of intestinal transplantation. RECENT FINDINGS Three important factors that have allowed improving results during the last few years are reviewed here. The first relates to the development of a different approach to tackle the underlying cause of intestinal failure and to the patient's characteristics in terms of liver function, age, and body size. The second involves immune modulation and especially the immunosuppressive regimen at induction. The third refers to posttransplantation monitoring, in particular the diagnosis and treatment of intestinal graft rejection and lymphoproliferative disorders. Patient status and referral for intestinal transplantation remain debated. The Intestinal Transplant Registry and a report from an individual program have demonstrated the relationship between a patient's pretransplant status and outcome. Candidacy for intestinal transplantation was analysed in a European survey of home parenteral nutrition patients. Early referral and listing are important for successful outcomes after intestinal grafting. SUMMARY Patient management should include therapies adapted to each stage of intestinal failure based on a multidisciplinary approach in centers involving surgery, gastroenterology, parenteral nutrition expertise, home parenteral nutrition programs, and liver-intestinal transplantation experience. Timing for referral of patients in specialized centers remains a crucial issue.

Abstract
AIM: To observe the histopathological changes in transplanted small bowel from a patient developing acute antibody-mediated rejection (AMR) and to perform a literature review.
METHODS: The resected allograft was fixed in 10% buffered formalin, embedded in paraffin, sectioned, and stained with hematoxylin and eosin. Morphological changes in the mucosa, intestinal wall and mesentery were observed by two pathologists separately. Acute rejection, vascular lesions and related changes were assessed. Immunohistochemical staining of C4d was also performed.
RESULTS: AMR lesions were widely distributed in the allograft, involving muscular arteries, arterioles, capillaries, vasa vasorum, venules and veins. The most serious AMR was observed in arterioles located in the submucosa and vasa vasorum. Main morphological changes included fibrous necrosis of blood vessel wall, thrombosis, and leucocyte margination. Neutrophilic granulocyte infiltration was noted in the edematous interstitium surrounding the involved blood vessels, with numerous erythrocytes extravasated. The fibrocollagenous network and part of the smooth muscle cells of the outer layer of the muscularis externa showed fibrous necrosis. Foci of lysis were present in the outer layer of arteries adjacent to the involved vasa vasorum. Foci of medial necrosis in the arteries were also observed. Immunohistochemical staining showed C4d deposition in the involved blood vessels. The blood vessels in the lamina propria showed congestion and significant dilation, and thrombosis was occasionally observed. No morphological changes were found in the crypt epithelium. There was no acute rejection in the mucosa.
CONCLUSION: Fibrous necrosis of blood vessel wall and thrombosis are main morphological changes in the transplanted small bowel after severe AMR. All types of blood vessels in the allograft can be involved, but the lesion in mucosal blood vessels may not reflect the most serious injury. Therefore, early diagnosis of AMR can not rely on the biopsy of intestinal mucosa.

Abstract
Context.—Intestinal transplant has become a standard treatment option in the management of patients with irreversible intestinal failure. The histologic evaluation of small-bowel allograft biopsy specimens plays a central role in assessing the integrity of the graft. It is essential for the management of acute cellular and chronic rejection; detection of infections, particularly with respect to specific viruses (cytomegalovirus, adenovirus, Epstein-Barr virus); and immunosuppression-related lymphoproliferative disease.Objective.—To provide a comprehensive review of the literature and illustrate key histologic findings in small-bowel biopsy specimen evaluation of patients with small-bowel or multivisceral transplants.Data Sources.—Literature review using PubMed (US National Library of Medicine) and data obtained from national and international transplant registries in addition to case material at Columbia University, Presbyterian Hospital, and Mount Sinai Medical Center, New York, New York.Conclusions.—Key to the success of small-bowel transplantation and multivisceral transplantation are the close monitoring and appropriate clinical management of patients in the posttransplant period, requiring coordinated input from all members of the transplant team with the integration of clinical, laboratory, and histopathologic parameters.

Abstract
INTRODUCTION The purpose of this study was to evaluate the correlation of plasma citrulline and rejection episodes in intestinal transplantation. METHODS From January 2007 until present, we performed citrulline assays on our small bowel patients. We investigated the correlation of these assays with the rejection status of the patients. The rejection status of the graft was defined based on graft biopsies. RESULTS Of 5195 citrulline samples, average serum citrulline levels decreased significantly when the patients presented a rejection episode. We found the following: no rejection, 17.38 microm/L; mild rejection, 13.05 microm/L; moderate rejection, 7.98 microm/L; and severe rejection, 6.05 microm/L. Our current emphasis is to determine the predictive power of citrulline with other biomarkers versus as a separate and isolated measurement. CONCLUSIONS In our study, citrulline levels correlated significantly with the rejection status of the graft. Serial follow-up of the patients using this assay may alert us to the possibility of increased alloreactivity and rejection episodes.

Abstract
Pediatric small bowel transplant recipients are susceptible to diarrhea due to rejection or infectious enteritis, particularly of viral etiology. The most common causes of viral enteritis in this setting are rotavirus, adenovirus, cytomegalovirus, and Epstein-Barr virus. This study is the first to compare the histologic findings of rotavirus infection with acute cellular rejection in small bowel transplant biopsies. Three patients with small bowel transplants had rapid stool antigen test-proven rotavirus infection. Endoscopic biopsies during infection were examined, including material from the allograft, native small bowel, stomach, and colon. Biopsies from 2 of the patients during unrelated episodes of mild acute cellular rejection were also evaluated. Blunting of villi was the most common finding in rotavirus infection. Additionally, there was a mononuclear infiltrate that was "top heavy," or denser towards the lumen. There were surface apoptoses but no increase in crypt apoptotic figures. In contrast, during mild acute cellular rejection, there was no villous blunting, the mononuclear infiltrate was diffuse, and there were increased crypt apoptosis. As expected, the changes of acute cellular rejection were confined to the graft, in contrast to rotavirus infection, in which case native bowel often had more pronounced changes. Although the small number of patients limits this study, several histologic features were helpful in identifying rotavirus infection. These were blunting of villi, distribution of the inflammatory infiltrate, number and location of apoptotic bodies, and anatomic location of the effect. A larger follow-up study would be valuable to confirm these findings.

Abstract
BACKGROUND Subclinical rejection (SCR) is a known entity in various solid organ transplants but not in intestinal transplantation. METHODS The purpose of this study is to characterize the presence and effect of SCR in small intestinal transplantation (Itx). A total of 151 patients who underwent Itx and maintained a functioning graft for at least 3 months after Itx were investigated. The clinicopathological characteristics associated with a SCR episode within 3 months after Itx were analyzed. Cox regression with the landmark method (the landmark time being 3 months after Itx) was used for the analyses of overall graft survival and cause-specific hazard rate of SCR. RESULTS A total of 2744 small intestinal transplant biopsies within 3 months after Itx were available for retrospective evaluation; 171 cases (6.2%) were determined as SCR and 78 patients (51.7%) experienced SCR episode within 3 months after Itx. Adult patients were associated with a significantly higher occurrence of a SCR episode (P=0.001). Overall graft survival at 5 years posttransplant for patients experiencing SCR within 3 months posttransplant and for patients without SCR was 37.2% and 60.2%, respectively (P=0.009). Cause-specific hazard rate analysis showed that a SCR episode was associated with a significantly higher hazard rate of death due to infection (P=0.005). CONCLUSIONS A SCR episode in the initial postoperative period of Itx is a significant factor for unfavorable graft prognosis, likely representing alloimmune injury ultimately resulting in patient morbidity due to infection.

Abstract
INTRODUCTION Intestinal transplantation has become a life-saving therapy in patients with irreversible loss of intestinal function and complications of total parenteral nutrition. DISCUSSION The patient and graft survival rates have improved over the last years, especially after the introduction of tacrolimus and rapamycin. However, intestinal transplantation is more challenging than other types of solid organ transplantation due to its large amount of immune competent cells and its colonization with microorganisms. Moreover, intestinal transplantation is still a low volume procedure with a small number of transplanted patients especially in Germany. A current matter of concern is the late referral of intestinal transplant candidates. CONCLUSION Thus, patients often present after onset of life-threatening complications or advanced cholestatic liver disease. Earlier timing of referral for candidacy might result in further improvement of this technique in the near future.
