Abstract
Evans syndrome (ES) is a rare and chronic autoimmune disease characterized by autoimmune hemolytic anemia and immune thrombocytopenic purpura with a positive direct anti-human globulin test. It is classified as primary and secondary, with the frequency in patients with autoimmune hemolytic anemia being 37%–73%. It predominates in children, mainly due to primary immunodeficiencies or autoimmune lymphoproliferative syndrome. ES during pregnancy is associated with high fetal morbidity, including severe hemolysis and intracranial bleeding with neurological sequelae and death. The clinical presentation can include fatigue, pallor, jaundice and mucosal bleeding, with remissions and exacerbations during the person’s lifetime, and acute manifestations as catastrophic bleeding and massive hemolysis. Recent molecular theories explaining the physiopathology of ES include deficiencies of CTLA-4, LRBA, TPP2 and a decreased CD4/CD8 ratio. As in other autoimmune cytopenias, there is no established evidence-based treatment and steroids are the first-line therapy, with intravenous immunoglobulin administered as a life-saving resource in cases of severe immune thrombocytopenic purpura manifestations. Second-line treatment for refractory ES includes rituximab, mofetil mycophenolate, cyclosporine, vincristine, azathioprine, sirolimus and thrombopoietin receptor agonists. In cases unresponsive to immunosuppressive agents, hematopoietic stem cell transplantation has been successful, although it is necessary to consider its potential serious adverse effects. In conclusion, ES is a disease with a heterogeneous course that remains challenging to patients and physicians, with prospective clinical trials needed to explore potential targeted therapy to achieve an improved long-term response or even a cure.

Abstract
Hemolysis after solid organ transplantation can be caused by both immune and non-immune-mediated mechanisms, and the evaluation must take into account issues distinctive to the post-transplant period. Autoimmune hemolytic anemia usually occurs within the first year and has been attributed to immunosuppressive treatment, infections, or underlying post-transplant lymphoproliferative disorder. Review of the literature revealed 59 cases with autoimmune hemolytic anemia mostly in children after liver transplantation. Almost all of the patients at the time of diagnosis received immunosuppression with tacrolimus, and first-line treatment with steroids and/or intravenous immunoglobulin was ineffective for complete remission. Rituximab was used as second-line treatment especially in patients with underlying lymphoproliferative disorders whereas sirolimus showed encouraging results.

Abstract
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.

Abstract
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.

Abstract
Cytopenias are common among pediatric SOT; however, autoimmune cytopenias are infrequently reported. We report five cases of autoimmune cytopenias in pediatric LT patients: two with isolated IgG-mediated AIHA, two with ITP, and one with Evans syndrome (ITP and AIHA). All patients were maintained on tacrolimus as immunosuppression. Viral illness commonly preceded the autoimmune cytopenias. All patients responded well to medical therapy (steroids, intravenous immunoglobulin, and rituximab) and lowering tacrolimus serum level. Prognosis appears to be worse when more than one cell line (e.g., Evans syndrome) is affected, and/or there is no preceding viral illness. A critical literature review of autoimmune cytopenias in children following SOT is conducted. Autoimmune cytopenias are a rarely reported complication of pediatric SOT, but clinicians taking care of pediatric transplant recipients need to be aware of this complication.

Abstract
Evans syndrome (ES) is a chronic hematological disorder characterized by autoimmune hemolytic anemia and immune-mediated thrombocytopenia that often requires profound and long-term immunosuppression. Only a few small case series or single case studies of autologous and allogeneic hematopoietic stem cell transplantation (HSCT) in patients with ES have been reported in the literature, with long-term remissions being observed after both autologous and allogeneic HSCT. Patients with ES suffering from refractory disease, multiple relapses and serious disease-related complications should be offered allogeneic HSCT, which is the only treatment with curative potential. Autologous HSCT might be preferable in patients with serious pre-existing comorbidities lacking an HLA-identical donor. Owing to the rarity of this disease and the small number of patients receiving HSCT for ES, prospective controlled studies on this approach are not available. A prospective registration of patients transplanted for ES would allow the development of optimal transplant strategies.

Abstract
Chronic graft-versus-host disease (GVHD) is a major complication after allogeneic haematopoietic stem cell transplantation (HSCT). Not only is it the major cause of late mortality in HSCT patients, but it also accounts for significant morbidity. Much of the literature on chronic GVHD has focused on adults. Chronic GVHD is of major importance in children, especially since they have years to live following the complications of chronic GVHD and its therapy. The goal is to review incidence, manifestations, and therapies, especially when applicable to the paediatric population.

Abstract
Five-year survival rates for childhood cancer now exceed 80% and with the significant progress made by the transplant community in developing less toxic conditioning regimens and in the treatment of posttransplant complications, allo-hematopoietic stem cell transplantation (HSCT) contributes significantly to that population of long-term survivors. In this context, the acute and long-term toxicities of chronic graft-versus-host disease (cGVHD) have an ever-increasing effect on organ function, quality of life, and survival; patients and families who initially felt great relief to be cured from the primary disease, now face the challenge of a chronic debilitating illness for which preventative and treatment strategies are suboptimal. Hence, the development of novel strategies that reduce and or control cGVHD, preserve graft-versus-tumor effects, facilitate engraftment and immune reconstitution, and enhance survival after allo-HSCT represents one of the most significant challenges facing physician-scientists and patients.

Abstract
We describe here an immune pancytopenia occurring soon after liver transplantation. Viral causes and allo- and/or auto-antibodies transferred with the graft have been excluded. The condition was concomitant with symptoms compatible with clinical onset of acute graft-versus-host disease. Both pancytopenia and clinical symptoms resolved rapidly under prednisone and intravenous immunoglobulins. We believe that the immune pancytopenia was due to the passive transfer of donor's lymphocytes within the graft and their persistence in peripheral blood in the recipient.

Abstract
A 3 and 1/2-yr-old boy underwent matched unrelated stem cell transplantation (SCT) for hyper-IgM syndrome. He developed acute and chronic skin graft-vs.-host disease (GVHD). Ten months following SCT he presented with severe hemolytic anemia and thrombocytopenia (Evans' syndrome). Treatment included high-dose steroids, intravenous immunoglobulins, cyclosporine, mycophenolate mofetil, chemotherapeutic agents (cyclophosphamide, vincristine, VP-16), immunoadsorption, and anti-CD20 and anti-CD52 monoclonal antibodies without response. The patient died 16 months after SCT.

Abstract
This article reviews acute graft vs. host disease (GVHD) as a complication of orthotopic liver transplantation (OLT). The incidence, presentation, clinical course and outcome of GVHD after OLT are summarized and the pathogenesis is discussed, drawing parallels with GVHD after allogeneic haematopoietic stem cell transplantation. Risk factors for GVHD after OLT are examined and the potential role of donor lymphocyte macrochimerism in the recipient peripheral blood as a diagnostic aid for GVHD is discussed. Finally, treatment of GVHD after OLT is reviewed with particular emphasis on the potential role of some of the newer biological agents.

Abstract
The skin, easily accessible for medical examination, is affected in many ways by liver transplantation. Mucocutaneous manifestations of advanced liver disease and dermatologic conditions associated with specific hepatic diagnoses generally improve after liver transplantation. Vasculitic lesions due to cryoglobulinemia associated with hepatitis C, and photosensitivity due to porphyria are occasional exceptions. Dermatologic diseases complicating the posttransplantation course can be challenging. Their presentation is sometimes unusual and their course severe. Infections with rare organisms alone or in combination may occur. Our intent is to provide an overview of the current knowledge regarding nontumoral dermatologic problems associated with liver transplantation by summarizing the available information from all documented case reports.

Abstract
Anemia is common after liver transplantation, with the incidence ranging from 4.3% to 28.2% depending on the criteria used to define anemia. The cause of anemia is unidentified in the majority of patients, and it is likely to be multifactorial. Immunosuppressive-medication-induced bone marrow suppression is perhaps the most common cause of unexplained anemia. Chronic blood loss, iron deficiency, hemolysis, and renal insufficiency are other potential causes of chronic anemia. Rare causes, somewhat unique to transplantation, include aplastic anemia, graft-versus-host disease (GVHD), and lymphoproliferative disease. Anemia due to immunosuppressive medication is challenging, since almost all drugs currently used for this purpose cause anemia, but the renal-sparing property of sirolimus may benefit the subgroup in which renal insufficiency is contributing to anemia. Aplastic anemia is seen in young patients transplanted for non-A, non-B, non-C, fulminant hepatic failure. It is thought to be immunologically mediated, secondary to an unknown viral infection, and is associated with a grave prognosis. GVHD is another infrequent (approximately 1% of transplant recipients) but serious cause of severe anemia that carries a dismal prognosis. Lymphoproliferative disorder, too may rarely rare cause anemia and it may respond to reduction of immunosuppression. Recipients of solid-organ transplants do not mount a significant increase in erythropoietin in response to anemia. In conclusion, though there are no data on the response of anemia to erythropoietin in liver transplant recipients, it appears to benefit other solid-organ-transplant recipients with anemia.

Abstract
Posttransplantation lymphoproliferative disease (PTLD) presenting as an Epstein-Barr-virus (EBV)-related nasal plasmacytoma developed in a renal-allograft recipient 13 years after transplantation. Systemic dissemination occurred despite immunosuppression withdrawal, surgery, irradiation, and chemotherapy. A nonmyeloablative hematopoietic-stem-cell-transplantation (HSCT) with peripheral blood HSC from the kidney donor was performed. With the onset of graft-versus-host disease, resolution of the systemic disease was demonstrated clinically and molecularly by serial quantification of plasma EBV-DNA. Isolated relapse occurred in the central nervous system (CNS), a known tumour sanctuary site, ultimately leading to death. Nonmyeloablative HSCT might be considered a cellular therapy for PTLD, but possible CNS relapse must be effectively tackled.

Abstract
BACKGROUND Red blood cell (RBC) alloantibodies are present in up to 14% of white recipients of liver transplants and can cause severe delayed hemolysis. METHODS A retrospective survey showed 17 cases (8.8%) of RBC alloantibodies in 192 consecutive Chinese recipients of liver transplants compared with a background hospital incidence of 3.7%. RESULTS The spectrum of RBC alloantibodies in Chinese patients was different than in white patients, with no anti-D or anti-K antibodies but a significant incidence of anti-Mi (29%) antibodies. There was a significantly increased incidence of transfusions in RBC alloantibody positive cases. Delayed hemolysis also resulted in higher day-7 bilirubin levels. A total of 7 to 86 antigen-positive units were issued in five RBC alloantibody cases, including three early deaths. Seven cases in the RBC alloantibody negative group, but none in the positive group, were salvaged by regraft. CONCLUSIONS Blood banks servicing transplant centers should be aware of ethnic patterns in RBC alloantibodies. Delayed hemolysis may jeopardize patient survival as the result of difficult postoperative stabilization, especially in cases requiring massive transfusion.

Abstract
We report a unique case of emergency living related donor orthotopic liver transplantation (OLT) for late fulminant reactivation of hepatitis B virus (HBV) after matched unrelated bone marrow transplantation (BMT) for chronic myeloid leukemia (CML). Cessation of lamivudine after BMT for HBV positive patients may carry risks of late fatal HBV reactivation. Similar to fulminant HBV reactivation in the general population, OLT under resumption of lamivudine can be life saving. In our case, concomitantly molecular relapse of CML at the time of liver failure was also cleared by OLT, possibly via a 'liver-graft vs. leukemia' effect. Liver rejection (graft vs. graft disease) was mild due to inherent immunocompromise of the marrow graft. Hence BMT recipients in stable remission should not be denied the opportunity for life-saving solid organ transplantation. A choice of marrow and liver donors with innate HBV immunity may be needed to give the additional advantage of long-term HBV clearance.

Abstract
As solid organ transplantation becomes increasingly common and complex, the demands on the transfusion service expand. Transplant recipients present unique challenges not only because of product availability but also because of specialized blood components, serologic problems, and immunologic effects of transfusion on the allograft and the recipient. Solid organ transplant recipients receive immunosuppressive agents that make them more susceptible to infectious or immunologic complications of transfusion such as cytomegalovirus infection and graft-versus-host disease. Other immunologic consequences of transfusion such as alloimmunization may also be severe, resulting in acute or chronic graft rejection. The transfusion specialist must recommend the optimal approach to reducing the risk of these complications in organ transplant recipients.

Abstract
Upper respiratory tract (URT) viral infections may cause severe consequences during myeloablative bone marrow transplantation (BMT). We present a patient with parainfluenza virus (PIV) infection during the course of BMT. He remained relatively asymptomatic during the course of cytopenia, but presented with complete loss of voice and severe laryngitis a few days after engraftment, which is not usual for adult PIV infections. Seroconversion to PIV and marked increase in antibody titres was demonstrated, with complete lymphoid engraftment. Our case illustrated that the virulence of some URT viral infections depend on host immune factors, and may remain latent until graft versus host responses can be mounted.
