Graft-versus-Host Disease Presenting With Pancytopenia After En Bloc Multiorgan Transplantation: Case Report and Literature Review

Acute graft versus host disease after liver transplantation: where do we stand?

Graft-versus-host disease (GVHD) is a rare complication after liver transplantation (LT), with an estimated incidence rate of 0.5% to 2% and a mortality rate as high as 75%. The classical target organs of GVHD include the intestines, liver, and skin. The damage of these organs is not easy to detect for the clinician as there is no widely accepted clinical or laboratory diagnostic tests; as a result, diagnosis and initiation of therapy are often delayed. Moreover, without prospective clinical trials to reference, evidence guiding therapy is limited. This review summarized the current knowledge, the potential applications and the clinical relevance of GVHD after LT, highlighting novel approaches in grading and management of GVHD.

Multidrug-resistant Klebsiella Pneumoniae Infection Led to Resection of the Graft in a Small Bowel Transplant Recipient: A Case Report and Review of the Literature

BACKGROUND

Infection due to multidrug-resistant Klebsiella pneumoniae is a common cause of graft resection after small bowel transplantation. We report a failed case in which the intestinal graft was resected 18 days after the operation due to postoperative infection with multidrug-resistant K pneumoniae and a literature review of other common causes of small bowel transplantation failure have been reported.

METHODS

A female, 29 years of age, underwent partial living small bowel transplantation for short bowel syndrome. After the operation, the patient was infected with multidrug-resistant K pneumoniae, even though various anti-infective regimens were employed. It further developed into sepsis and disseminated into intravascular coagulation, leading to exfoliation and necrosis of the intestinal mucosa. Finally, the intestinal graft had to be resected to save the patient's life.

RESULTS

Multidrug-resistant K pneumoniae infection often affects the biological function of intestinal grafts and can even lead to necrosis. Other common causes of failure, including postoperative infection, rejection, post-transplantation lymphoproliferative disorder, graft-vs-host disease, surgical complications, and other related diseases, were also discussed throughout the literature review.

CONCLUSIONS

Pathogenesis due to diverse and interrelated factors makes the survival of intestinal allografts a great challenge. Therefore, only by fully understanding and mastering the common causes of surgical failure can the success rate of small bowel transplantation be effectively improved.

How I diagnose and treat acute graft-versus-host disease after solid organ transplantation

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.

Graft versus host disease after liver transplantation following radiotherapy for the treatment of hepatocellular carcinoma: A case report and literature review

Graft versus host disease after solid organ transplantation is very rare. This article reports a case of graft versus host disease after liver transplantation following targeted therapy and radiotherapy for the treatment of hepatocellular carcinoma. The patient developed a symptomatic skin rash and pancytopenia 13 days after surgery, which was confirmed as graft versus host disease after liver transplantation by histopathology and fluorescence in situ hybridization. Early diagnosis of graft versus host disease after solid organ transplantation is difficult and often delayed due to nonspecific manifestations that overlap with other diseases. Currently, the treatment of graft versus host disease after liver transplantation occurs by either strengthening the immune suppression or weakening the immune suppression; however, there is no unified standard treatment strategy. We found that in addition to age, gender, and human leukocyte antigen type, preoperative radiotherapy is a likely risk factor for graft versus host disease after liver transplantation.

Chronic graft-versus-host disease in pancreas after kidney transplant recipients - An unrecognized entity

Graft-versus-host disease (GVHD), a common complication after peripheral blood stem cell or bone marrow transplantation, rarely occurs in kidney and pancreas transplant recipients. The true incidence may be confounded by the rarity of the disorder, with a resultant lack of appreciation of the diagnosis as a potential cause of common clinical manifestations such as cytopenias and immune dysfunction. Reports of GVHD in kidney and pancreas transplant recipients almost uniformly describe patients in the early posttransplant period (days to months) with the typical manifestations of acute GVHD involving the skin, liver, and intestines. In contrast, reports of solid organ transplant recipients with clinical features more consistent with chronic GVHD (cGVHD) are lacking, raising concern of underrecognition of this severe complication. Occurrence later after transplant may be even more likely to result in lack of recognition. We report 2 cases of possible cGVHD occurring in recipients of pancreas after kidney transplantation, which were diagnosed at 5.5 and 42 months after pancreas transplant. Both patients presented with severe pancytopenia, multiple opportunistic infections, and features suggestive of cGVHD. Transplant professionals should be aware of the possibility of acute and cGVHD in pancreas after kidney transplant recipients and be able to recognize the clinical manifestations.

Temporary Cessation of Immunosuppression for Infection May Contribute to the Development of Graft-vs-Host Disease After ABO-Incompatible Living Donor Liver Transplantation: A Case Report

Graft-vs-host disease (GVHD) after liver transplantation is a rare complication with a high mortality rate. A complex interplay between donor and recipient immunity plays a role in the development of GVHD. Infection following liver transplantation is one of the most common complications in a recipient of an organ transplant who is immunosuppressed. On clinical signs of infection, the immune reaction of the recipient can be reconstituted by withdrawal of immunosuppression in order to help combat infection. However, the discontinuation of immunosuppression could restore the donor's immune activity rather than that of the recipient. There is little information available as to whether the discontinuation of immunosuppression for severe infection could contribute to the development of GVHD in a patient who underwent ABO-incompatible (ABO-I) living donor liver transplantation (LDLT). Herein, we present a unique case of GVHD following ABO-I LDLT, for which the cessation of immunosuppression could be responsible.

Post-intestine transplant graft-vs-host disease associated with inclusion of a liver graft and with a high mortality risk

INTRODUCTION

This study reports the incidence, anatomic location, and outcomes of graft-vs-host disease (GVHD) at a single active intestine transplant center.

METHODS

Records were reviewed for all patients receiving an intestine transplant from 2003 to 2015. Pathology reports and pharmacy records were reviewed to establish the diagnosis, location, and therapeutic interventions for GVHD.

RESULTS

A total of 236 intestine transplants were performed during the study period, with 37 patients (16%) developing GVHD. The median time to onset of disease was 83 days, with 89% of affected patients diagnosed in the first year post-transplant. Mortality for affected patients was 54% in the 1 year after GVHD diagnosis. Skin lesions were the most common manifestation of GVHD. Other sites of disease included lungs, bone marrow, oral mucosa, large intestine, and brain. The incidence of GVHD was 16% in adult patients, and slightly lower in pediatric recipients (13%). In adults, increasing graft volume (isolated vs multi-organ) and liver inclusion were associated with increasing risk of GVHD, though this was not seen in pediatric patients.

CONCLUSION

Overall, 16% of intestine transplant recipients developed GVHD. GVHD is associated with high mortality, and disease in the lungs, brain, and bone marrow was universally fatal.

Improved survival after LTx-associated acute GVHD with mAb therapy targeting IL2RAb and soluble TNFAb: Single-center experience and systematic review

Acute graft-versus-host disease (GVHD) after liver transplant (LTx) is a rare complication with a high mortality rate. Recently, monoclonal antibody (mAb) treatment, specifically with anti-interleukin 2 receptor antibodies (IL2RAb) and anti-tumor necrosis factor-α antibodies (TNFAb), has gained increasing interest. However, evidence is mostly limited to case reports and the efficacy remains unclear. Here, we describe 5 patients with LTx-associated GVHD from our center and provide the results of our systematic literature review to evaluate the potential therapeutic benefit of IL2RAb/TNFAb treatment. Of the combined population of 155 patients (5 in our center and 150 through systematic search), 24 were given mAb (15.5%)-4 with TNFAb (2.6%) and 17 with IL2RAb (11%) ("mAb group")-and compared with patients who received other treatments (referred to as "no-mAb group"). Two-sided Fisher exact tests revealed a better survival when comparing treatment with mAb versus no-mAb (11/24 vs 27/131; P = .018), TNFAb versus no-mAb (3/4 vs 27/131; P = .034), and IL2RAb versus no-mAb (8/17 vs 27/131; P = .029). This systematic review suggests a beneficial effect of mAb treatment and a promising role for TNFAb and IL2RAb as a first-line strategy to treat LTx-associated acute GVHD.

Graft Versus Host Disease After Liver Transplantation in Adults: A Case series, Review of Literature, and an Approach to Management

BACKGROUND

Graft-versus-host-disease (GVHD) after liver transplantation (LT) is a deadly complication with very limited data on risk factors, diagnosis and management. We report a case series and a comprehensive review of the literature.

METHODS

Data were systematically extracted from reports of GVHD after LT, and from the United Network for Organ Sharing database. Group comparisons were performed.

RESULTS

One hundred fifty-six adult patients with GVHD after LT have been reported. Median time to GVHD onset was 28 days. Clinical features were skin rash (92%), pancytopenia (78%), and diarrhea (65%). Six-month mortality with GVHD after LT was 73%. Sepsis was the most common cause of death (60%). Enterobacter bacteremia, invasive aspergillosis, and disseminated Candida infections were frequently reported. Recipient age over 50 years is a risk factor for GVHD after LT. Hepatocellular carcinoma was overrepresented, whereas chronic hepatitis C was underrepresented, in reported United States GVHD cases relative to all United Network for Organ Sharing database LT cases. Mortality rate with treatment of GVHD after LT was 84% with high-dose steroids alone, 75% to 100% with regimens using dose increases of calcineurin inhibitors, and 55% with IL-2 antagonists. Mortality was 25% in small case series using the CD2-blocker alefacept or TNF-α antagonists.

CONCLUSIONS

Age older than 50 years and hepatocellular carcinoma appear to be risk factors for GVHD. Hepatitis C may be protective. High-dose steroids and calcineurin inhibitors are ineffective in the treatment of GVHD after LT. CD2-blockers and TNF-α antagonists appear promising. We propose a diagnostic algorithm to assist clinicians in managing adults with GVHD after LT.

Immunological basis for treatment of graft versus host disease after liver transplant

Graft versus host disease (GVHD) after liver transplant, although a rare disease, has a very high mortality rate. GVHD occurs due to immunoreactions caused by donor T lymphocytes and host cell surface antigens resulting in proliferation and clonal expansion of T lymphocyte. Migration of effector cells, including macrophages, NK cells and cytotoxic T lymphocyte, to the target organs such as skin, intestine and bone marrow results in skin rashes, diarrhea and bone marrow depression. GVHD is diagnosed by clinical symptoms, histopathological findings and by the presence of chimerism. The delayed diagnosis, opportunistic infections and lack of definitive treatment of post orthotopic liver transplant (OLT)-GVHD results in sepsis and multi-organ failure leading to very low survival rates. In this review, we have focused on early diagnosis and critically discuss novel treatment modalities to decrease the incidence of GVHD.

Extracorporeal photopheresis in solid organ transplant-associated acute graft-versus-host disease

BACKGROUND

Extracorporeal photopheresis (ECP) culls pathogenic T lymphocytes, be these the clones of cutaneous T-cell lymphoma, or mediators of chronic graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (BMT-GVHD). Whether or not ECP may have an effect in the rarer instances of solid organ transplantation-associated GVHD (SOT-GVHD) is unclear. Mortality rates in SOT-GVHD rival those of transfusion-associated GVHD, with fatalities preceded by pancytopenia and peripheral blood chimerism (PBC) levels exceeding 20%. ECP has been described in two SOT-GVHD cases to date, with one surviving.

STUDY DESIGN AND METHODS

Clinicolaboratory features (including HLA relationships) in a case of multivisceral transplantation were reviewed from the time of surgery to the onset and progression of SOT-GVHD. ECP, which was introduced as a less immunosuppressive and more selective intervention, was assessed for its effect on serial PBC (as measured by short-tandem-repeat analysis) and clinical outcome.

RESULTS

Multivisceral SOT-GVHD manifested with erythroderma, neutropenic sepsis, and PBC increasing from 6% on Posttransplant Day (PTD) 38 to 78% by PTD 60 (at a doubling time of 6 days despite corticosteroids). ECP was administered on PTDs 62 and 67 and was associated with the first evidence of PBC decay to 67% on PTD 69. Death nevertheless ensued on the last day of salvage antithymocyte globulin (PTDs 69-73) despite further PBC reduction to 41%.

CONCLUSION

Further study is needed to determine if the sooner or more frequent application of ECP might attenuate the high case fatality rates of SOT-GVHD.

Successful treatment of acute severe graft-versus-host-disease in a pancreas-after-kidney transplant recipient: case report

The development of acute graft-versus-host-disease (GVHD) in recipients of pancreas transplants is a rare and quite often a fatal post-transplantation complication. We present a 38-year-old male with a longstanding history of type 1 diabetes mellitus and end-stage kidney disease, with a living unrelated kidney transplant from his wife for 3 years, who received an enteric-drained 5-antigen HLA-mismatched deceased-donor pancreas. Five weeks after transplantation, he presented with spiking fevers, severe skin rash, diarrhea, pancytopenia, and increasingly abnormal liver function tests. Skin biopsies were consistent with grade 3 acute GVHD. The patient was treated for GVHD with escalated doses of tacrolimus, pulse doses of steroids, and basiliximab. He was discharged after a 4-week hospital stay with complete resolution of his rash, fever, abnormal liver enzymes, and leukopenia. He remained in good health with excellent kidney and pancreas allograft function 3 years later.

Fluorescence in situ hybridization (FISH) as an aid for the diagnosis of graft-versus-host disease in two multivisceral organ transplant patients

We herein describe 2 cases of adult multivisceral transplant patients who developed graft-versus-host disease manifesting predominantly as lichenoid skin papules and plaques. The diagnosis was supported by histopathology but ultimately corroborated by the utilization of the fluorescence in situ hybridization (FISH) technique using X and Y chromosome probes on unstained biopsy slides. In both cases, FISH revealed a high percentage of donor-derived cells as part of the inflammatory infiltrate in the skin biopsy. This report adds to the previous publications showing the utility of FISH in corroborating the diagnosis of graft-versus-host disease in transplant patients with unmatched sex donor.

Graft-versus-host disease after liver transplantation: A comprehensive literature review

AIM: To determine the factors affecting mortality in patients who developed graft-versus-host disease (GvHD) after liver transplantation (LT).

METHODS: We performed a review of studies of GvHD following LT published in the English literature and accessed the PubMed, Medline, EBSCO, EMBASE, and Google Scholar databases. Using relevant search phrases, 88 articles were identified. Of these, 61 articles containing most of the study parameters were considered eligible for the study. Risk factors were first examined using a univariate Kaplan-Meier model, and variables with a significant association (P < 0.05) were then subjected to multivariate analyses using a Cox proportional-hazards model.

RESULTS: The 61 articles reported 87 patients, 58 male and 29 female, mean age, 40.4 ± 15.5 years (range: 8 mo to 74 years), who met the inclusion criteria for the present study. Deaths occurred in 59 (67.8%) patients, whereas 28 (32.2%) survived after a mean follow-up period of 280.8 ± 316.2 d (range: 27-2285 d). Among the most frequent symptoms were rash (94.2%), fever (66.6%), diarrhea (54%), and pancytopenia (54%). The average time period between LT and first symptom onset was 60.6 ± 190.1 d (range: 2-1865 d). The Kaplan-Meier analysis revealed that pancytopenia (42.8% vs 59.3%, P = 0.03), diarrhea (39.2% vs 61.0%, P = 0.04), age difference between the recipient and the donor (14.6 ± 3.1 years vs 22.6 ± 2.7 years, P < 0.0001), and time from first symptom occurrence to diagnosis or treatment (13.3 ± 2.6 mo vs 15.0 ± 2.3 mo, P < 0.0001) were significant factors affecting mortality, whereas age, sex, presence of rash and fever, use of immunosuppressive agents, acute rejection before GvHD, etiological causes, time of onset, and donor type were not associated with mortality risk. The Cox proportional-hazards model, determined that an age difference between the recipient and donor was an independent risk factor (P = 0.03; hazard ratio, 7.395, 95% confidence interval, 1.2-46.7).

CONCLUSION: This study showed that an age difference between the recipient and donor is an independent risk factor for mortality in patients who develop GvHD after LT.

Acute graft versus host disease after orthotopic liver transplantation

Graft versus host disease (GVHD) is an uncommon complication after orthotopic liver transplantation (OLT) with an incidence of 0.1–2%, but an 80–100% mortality rate. Patients can present with skin rashes, diarrhea, and bone marrow aplasia between two to eight weeks after OLT. Diagnosis of GVHD is made based on clinical and histologic evidence, supported by chimerism studies showing donor HLA alleles in the recipient bone marrow or blood. Several therapeutic approaches have been used for the management of GVHD after OLT including increased immunosuppression, decreased immunosuppression, and cellular therapies. However, success rates have been low, and new approaches are needed.

Unsuccessful treatment of four patients with acute graft-vs-host disease after liver transplantation

AIM: To investigate appropriate therapeutic strategies for graft-vs-host disease (GVHD) following liver transplantation.

METHODS: Four patients who developed GVHD after liver transplantation in West China Hospital were included in this study. Therapeutic strategies with augmentation or withdrawal of immunosuppressants combined with supportive therapy were investigated in these patients. In addition, a literature review of patients who developed GVHD after liver transplantation was performed.

RESULTS: Although a transient response to initial treatment was detected, all four patients died of complications from GVHD: one from sepsis with multiple organ failure, one from gastrointestinal bleeding, and the other two from sepsis with gastrointestinal bleeding. Few consensuses for the treatment of GVHD after liver transplantation have been reached.

CONCLUSION: New and effective treatments are required for GVHD after liver transplantation to improve the prognosis of patients with this diagnosis.
