Abstract
Acute graft-versus-host disease (GVHD) is a rare complication after solid organ transplantation (SOT) that carries high mortality. Caused by immunocompetent donor leukocytes within the transplanted organ, which become activated against recipient tissues, GVHD typically develops 2 to 12 weeks after SOT and can affect the skin, gastrointestinal tract, liver, and bone marrow. Signs and symptoms are nonspecific and include a rash, nausea, appetite loss, diarrhea, and cytopenias. Pancytopenia from marrow-directed GVHD is the primary driver of mortality. The diagnosis of GVHD is often delayed but should be confirmed by biopsy of an affected organ. Evidence of donor chimerism in blood or marrow supports the diagnosis. When GVHD is diagnosed we initiate treatment with systemic corticosteroids. At that time, if GVHD only involves skin or oral mucosa we also decrease maintenance immunosuppression levels to allow the recipient to reject the donor immune cells. For GVHD involving the marrow we initiate an allogeneic hematopoietic cell donor search early. In this article, we describe 3 cases of GVHD after SOT, outline our approach to diagnosis and management, and then provide analysis of the 3 instructive cases.

Abstract
OBJECTIVE We aimed to assess whether native spleen preservation during visceral transplantation (VT) affects graft-versus-host-disease (GVHD) incidence. SUMMARY BACKGROUND DATA GVHD is one of the most severe and frequently lethal hematological complications after VT procedures. Because there is no specific treatment for GVHD, it is imperative to develop a strategy to reduce donor lymphocyte engraftment and proliferation. METHODS Our study included both clinical and experimental data. A total of 108 patients were divided into 3 groups: a native spleen preservation group, a native spleen removal with no donor spleen group, and a donor spleen included (allogeneic spleen) group. We also used an allogeneic VT rat model, in which recipients were divided into 2 groups: a native spleen preservation (+SP) group and a native spleen removal (-S) group. Skin rash appearance, histopathological changes, chimerism, and spleen effects on circulating allogeneic T-cells were assessed. RESULTS The patients with native spleen preservation showed a lower rate of GVHD ( P <.001) and better survival ( P <.05) than those in the other groups. Skin and histological signs of GVHD were lower in the rats in the +SP group ( P <.05). The donor T-cell frequency in the bloodstream and skin was also significantly reduced when the native spleen was preserved ( P <.01 and P <.0001, respectively). CONCLUSIONS The clinical and experimental data indicate that recipient spleen preservation protects against GVHD after VT, and donor cell clearance from the bloodstream by spleen macrophages could be the underlying mechanism. Therefore, spleen preservation should be considered in VT procedures, whenever possible.

Abstract
PURPOSE OF REVIEW The intestine is the most immunologically complex solid organ allograft with the greatest risk of both rejection and graft-versus-host disease (GVHD). High levels of immunosuppression are required, further increasing morbidity. Due to low volume of transplants and few centers with experience, there is paucity of evidence-based, standardized, and effective therapeutic regimens. We herein review the most recent data about immunosuppression, focusing on novel and emerging therapies. RECENT FINDINGS Recent data are moving the field toward increasing use of basilixumab and consideration of alemtuzumab for induction and inclusion of mammalian target of rapamycin inhibitors and antimetabolites for maintenance. For rejection, we highlight novel roles for tumor necrosis factor-α inhibition, α4β7 integrin inhibition, microbiome modulation, desensitization protocols, and tolerance induction strategies. We also highlight emerging novel therapies for GVHD, especially the promising role of Janus kinase inhibition. SUMMARY New insights into immune pathways associated with rejection and GVHD in intestinal allografts have led to an evolution of therapies from broad-based immunosuppression to more targeted strategies that hold promise for reducing morbidity from infection, rejection, and GVHD. These should be the focus of further study to facilitate their widespread use.

Treatment of Acute Graft-versus-Host Disease in Liver Transplant Recipients. Case Rep Transplant 2021; 2021:8981429. [PMID: 34888111 PMCID: PMC8651419 DOI: 10.1155/2021/8981429] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 11/05/2021] [Indexed: 11/17/2022] Open
Abstract
Acute graft-versus-host disease (aGvHD) is a rare complication of liver transplantation associated with high morbidity and mortality. Death typically occurs due to complications related to severe infection, shock, and multiorgan failure. The clinical presentation involves dysfunction of multiple organ systems with overlapping symptoms that often results in a diagnostic delay. As there are a limited number of cases reported in the literature, there are no clear guidelines for treatment. Many different therapeutic measures have been utilized that target various immune system pathways, but steroids remain the first line of therapy. We report on two patients who developed aGvHD after liver transplantation who were treated with ruxolitinib, a novel Janus kinase 1/2 (JAK) inhibitor that has been shown to improve outcomes in steroid refractory cases of aGvHD after allogenic hematopoietic stem cell transplantation. We reviewed the literature to discuss various therapeutic options currently available for aGvHD after liver transplantation.

Graft Versus Host Disease After Intestinal Transplantation: A Single-center Experience. Transplant Direct 2021; 7:e731. [PMID: 34291153 PMCID: PMC8291352 DOI: 10.1097/txd.0000000000001187] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 04/13/2021] [Indexed: 12/25/2022] Open
Abstract
Supplemental Digital Content is available in the text. Background. Graft versus host disease (GVHD) is an uncommon but highly morbid complication of intestinal transplantation (ITx). In this study, we reviewed our 17-y experience with GVHD focusing on factors predicting GVHD occurrence and survival. Methods. Retrospective review of 271 patients who received 1 or more ITx since program inception in 2003 with survival analysis using Cox proportional hazard modeling. Results. Of 271 patients, 28 developed GHVD 34 (18–66) d after ITx presenting with rash or rash with fever in 26, rectosigmoid disease in 1, and hemolysis in 1; other sites, mainly rectosigmoid colon, were involved in 13. Initial skin biopsy demonstrated classic findings in 6, compatible findings in 14, and no abnormalities in 2. Additional sites of GVHD later emerged in 14. Of the 28 patients, 16 died largely from sepsis, the only independent hazard for death (hazard ratio [HR], 37.4181; P = 0.0008). Significant (P < 0.0500) independent hazards for occurrence of GVHD in adults were pre-ITx functional intestinal failure (IF) (HR, 15.2448) and non-IF diagnosis (HR, 20.9952) and early post-ITx sirolimus therapy (HR, 0.0956); independent hazards in children were non-IF diagnosis (HR, 4.3990), retransplantation (HR, 4.6401), donor:recipient age ratio (HR, 7.3190), and graft colon omission (HR, 0.1886). Variant transplant operation was not an independent GVHD hazard. Conclusions. Initial diagnosis of GVHD after ITx remains largely clinical, supported but not often confirmed by skin biopsy. Although GVHD risk is mainly recipient-driven, changes in donor selection and immunosuppression practice may reduce incidence and improve survival.

Abstract
PURPOSE OF REVIEW Despite improvement in short-term outcomes after intestinal transplantation in the last 20 years, long-term rates of graft attrition and patient survival remain unchanged, with worse outcomes compared with other solid organ transplants. This review investigates the multiple causes of late graft loss, including chronic rejection, infection, graft-versus-host disease, posttransplant lymphoproliferative disorder and postsurgical complications. RECENT FINDINGS New insights into immunology of the intestine and evolution of immunosuppression, as well as review of current persistent causes of late graft loss, shed light on findings that may help improve long-term intestinal allograft survival. SUMMARY Although intestinal transplantation remains a life-saving intervention with significant advancements since its inception, further understanding of mechanisms of injury is needed to improve long-term outcomes and prevent late intestinal graft loss.
