Abstract
BACKGROUND The impact of Fontan-associated liver disease (FALD) on post-transplant mortality and indications for combined heart-liver transplant (CHLT) in adult Fontan patients remains unknown. OBJECTIVES The purpose of this study was to assess the impact of FALD on post-transplant outcomes and compare HT vs CHLT in adult Fontan patients. METHODS We performed a retrospective-cohort study of adult Fontan patients who underwent HT or CHLT across 15 centers. Inclusion criteria were as follows: 1) Fontan; 2) HT/CHLT referral; and 3) age ≥16 years at referral. Pretransplant FALD score was calculated using the following: 1) cirrhosis; 2) varices; 3) splenomegaly; or 4) ≥2 paracenteses. RESULTS A total of 131 patients (91 HT and 40 CHLT) were included. CHLT recipients were more likely to be older (P = 0.016), have a lower hemoglobin (P = 0.025), require ≥2 diuretic agents pretransplant (P = 0.051), or be transplanted in more recent decades (P = 0.001). Postmatching, CHLT demonstrated a trend toward improved survival at 1 year (93% vs 74%; P = 0.097) and improved survival at 5 years (86% vs 52%; P = 0.041) compared with HT alone. In patients with a FALD score ≥2, CHLT was associated with improved survival (1 year: 85% vs 62%; P = 0.044; 5 years: 77% vs 42%; P = 0.019). In a model with transplant decade and FALD score, CHLT was associated with improved survival (HR: 0.33; P = 0.044) and increasing FALD score was associated with worse survival (FALD score: 2 [HR: 14.6; P = 0.015], 3 [HR: 22.2; P = 0.007], and 4 [HR: 27.8; P = 0.011]). CONCLUSIONS Higher FALD scores were associated with post-transplant mortality. Although prospective confirmation of our findings is necessary, compared with HT alone, CHLT recipients were older with higher FALD scores, but had similar survival overall and superior survival in patients with a FALD score ≥2.

Abstract
Preformed donor-specific antibodies are associated with a higher risk of rejection and worse graft survival in organ transplantation. However, in heart transplantation, the risk and benefit balance between high mortality on the waiting list and graft survival may allow the acceptance of higher immunologic risk donors in broadly sensitized recipients. Transplanting donor-recipient pairs with a positive complement dependent cytotoxic (CDC) crossmatch carries the highest risk of hyperacute rejection and immediate graft loss and is usually avoided in kidney transplantation. Herein we report the first successful simultaneous heart-kidney transplant with a T- and B-cell CDC crossmatch positive donor using a combination of rituximab, intravenous immunoglobulin, plasmapheresis, bortezomib and rabbit anti-thymocyte globulin induction followed by eculizumab therapy for two months post-transplant. In the year following transplantation, both allografts maintained stable graft function (all echocardiographic left ventricular ejection fractions ≥ 65%, eGFR>60) and showed no histologic evidence of antibody-mediated rejection. In addition, the patient has not developed any severe infections including cytomegalovirus or BK virus infection. In conclusion, a multitarget immunosuppressive regimen can allow for combined heart/kidney transplantation across positive CDC crossmatches without evidence of antibody-mediated rejection or significant infection. Longer follow-up will be needed to further support this conclusion.

Abstract
Simultaneous liver and kidney (SLK) transplantation is considered the best treatment modality among selected patients with both chronic kidney disease (CKD) and end-stage liver disease (ESLD). Since the first SLK transplant in 1983, the number of SLK transplants has increased worldwide, and particularly in the United States since the implementation of the MELD system in 2002. SLK transplants are considered a relatively low immunological risk procedure evidenced by multiple studies displaying the immunomodulatory properties of the liver on the immune system of SLK recipients. SLK recipients demonstrate lower rates of both cellular and antibody-mediated rejection on the kidney allograft when compared to kidney transplant-alone recipients. Therefore, SLK transplants in the setting of preformed donor-specific HLA antibodies (DSA) are a common practice, at many centers. Acceptance and transplantation of SLKs are based solely on ABO compatibility without much consideration of crossmatch results or DSA levels. However, some studies suggest an increased risk for rejection for SLK recipients transplanted across high levels of pre-formed HLA DSA. Despite this, there is no consensus regarding acceptable levels of pre-formed DSA, the role of pre-transplant desensitization, splenectomy, or immunosuppressive management in this unique population. Also, the impact of post-transplant DSA monitoring on long-term outcomes is not well-studied in SLK recipients. In this article, we review recent and relevant past articles in this field with a focus on the immunological risk factors among SLK recipients, and strategies to mitigate the negative outcomes among them.

Abstract
The long-term outcomes of positive crossmatch (+XM) simultaneous liver-kidney (SLK) transplantations are conflicting. We examined the association between crossmatch status and SLK outcomes in recipients discharged on tacrolimus and mycophenolate with or without steroids. We analyzed the Scientific Registry of Transplant Recipients for all primary SLK recipients between 2003 and 2020 with available crossmatch and induction data. We grouped recipients according to the crossmatch status: negative crossmatch (-XM; n = 3040) and +XM (n = 407). Kaplan-Meier curves were generated to examine recipient, death-censored liver, and death-censored kidney survival by crossmatch status. Cox proportional hazard models were used to investigate the association between crossmatch status and outcomes of interest with follow-up censored at 10 years. Models were adjusted for recipient age, sex, diabetes mellitus, Model for End-Stage Liver Disease score, duration on the liver waiting list, induction immunosuppression, steroid maintenance, hepatitis C infection, donor age and sex, local vs. shared organ, cold ischemia time, and previous liver transplantation status. In the univariable analysis, crossmatch status was not associated with recipient survival (log-rank p = 0.63), death-censored liver graft survival (log-rank p = 0.05), or death-censored kidney graft survival (log-rank p = 0.11). Compared with -XM, +XM recipients had a similar 1-year liver rejection rate, but higher kidney rejection rate (4.6% vs. 8.9%, p = 0.002). In the multivariable models, +XM status was not associated with deleterious long-term recipient, liver, or kidney grafts survival. -XM and +XM SLK transplantations have comparable long-term recipient, liver graft, and kidney survival with a slightly increased risk of early kidney allograft rejection in the +XM group. Crossmatch positivity in SLK transplantations should not influence the decision to use organs from a specific donor.

Abstract
Simultaneous liver-kidney transplant (SLKT) in the presence of antihuman leukocyte antigen (HLA) donor-specific antibodies (DSA) is a well-accepted practice. Herein, we describe the evolution of alloantibodies in a patient who received an SLKT. The pre-SLKT serum sample showed multiple strong DSA. As expected, all DSA cleared in a sample collected 4 days after the SLKT. Because of the primary nonfunction of the liver in the SLKT, the patient had a second liver transplant 4 days later. An abrupt increase in DSA levels against the kidney was detected 10 days after the second liver transplant. These DSA were refractory to treatment, and the transplanted kidney was lost due to antibody-mediated rejection (AMR). A detailed study of the HLA epitopes recognized by DSA and, after normalization with third-party alloantibodies to address the effect of multiple transfusions and liver allograft neutralization, showed that the elimination of these antibodies depended on the HLA antigens expressed by the transplanted liver cells. The return of DSA after removal of the first transplanted liver was associated with AMR in the transplanted kidney.

Abstract
BACKGROUND A safety net policy was implemented in August 2017 giving liver transplant alone (LTA) recipients with significant renal dysfunction posttransplant priority for subsequent kidney transplantation (KT). This study was undertaken to evaluate early outcomes under this policy. METHODS Adults undergoing LTA after implementation of the safety net policy and were subsequently listed for KT between 60 and 365 days after liver transplantation contained in United Network for Organ Sharing data were examined. Outcomes of interest were receipt of a kidney transplant and postliver transplant survival. Safety net patients were compared with LTA recipients not subsequently listed for KT as well as to patients listed for simultaneous liver-kidney (SLK) transplant yet underwent LTA and were not subsequently listed for KT. RESULTS There were 100 patients listed for safety net KT versus 9458 patients undergoing LTA without subsequent KT listing. The cumulative incidence of KT following listing was 32.5% at 180 days. The safety net patients had similar 1-year unadjusted patient survival (96.4% versus 93.4%; P = 0.234) but superior adjusted survival (hazard ratio0.133, 0.3570.960; P = 0.041) versus LTA recipients not subsequently listed for KT. Safety net patients had superior 1-year unadjusted (96.4% versus 75.0%; P < 0.001) and adjusted (hazard ratio0.039, 0.1260.406; P < 0.001) survival versus SLK listed patients undergoing LTA without subsequent KT listing. CONCLUSIONS The safety net appears to provide rapid access to KT with good early survival for those able to take advantage of it. Survival of patients unable to qualify for KT listing after LTA needs to be better understood before further limitation of SLK, however.

Abstract
BACKGROUND Combined liver-kidney transplantation (CLKT) improves survival for liver transplant recipients with renal dysfunction; however, the tenuous perioperative hemodynamic and metabolic milieu in high-acuity CLKT recipients increases delayed graft function and kidney allograft failure. We sought to analyze whether delayed KT through pumping would improve kidney outcomes following CLKT. METHODS A retrospective analysis (University of California Los Angeles [n = 145], Houston Methodist Hospital [n = 79]) was performed in all adults receiving CLKT at 2 high-volume transplant centers from February 2004 to January 2017, and recipients were analyzed for patient and allograft survival as well as renal outcomes following CLKT. RESULTS A total of 63 patients (28.1%) underwent delayed implantation of pumped kidneys during CLKT (dCLKT) and 161 patients (71.9%) received early implantation of nonpumped kidneys during CLKT (eCLKT). Most recipients were high-acuity with median biologic model of end-stage liver disease (MELD) score of, 35 for dCLKT and 34 for eCLKT (P = ns). Pretransplant, dCLKT had longer intensive care unit stay, were more often intubated, and had greater vasopressor use. Despite this, dCLKT exhibited improved 1-, 3-, and 5-year patient and kidney survival (P = 0.02) and decreased length of stay (P = 0.001), kidney allograft failure (P = 0.012), and dialysis duration (P = 0.031). This reduced kidney allograft futility (death or continued need for hemodialysis within 3 mo posttransplant) for dCLKT (6.3%) compared with eCLKT (19.9%) (P = 0.013). CONCLUSIONS Delayed implantation of pumped kidneys is associated with improved patient and renal allograft survival and decreased hospital length of stay despite longer kidney cold ischemia. These data should inform the ethical debate as to the futility of performing CLKT in high-acuity recipients.

Abstract
Recipients of simultaneous liver-kidney transplantations (SLKTs) have a lower risk of rejection compared with recipients of kidney transplants alone. However, there is disagreement about the impact of pretransplant anti-human leukocyte antigen sensitization on patient and kidney graft survival in the long term. The aim of the study was to evaluate the impact of the recipient immunological risk and comorbidities in renal graft outcomes on SLKT. We reviewed the SLKTs performed in our center from May 1993 until September 2017. Patient and graft survival were analyzed according to the immunological risk, comorbidities, liver and kidney rejection episodes, immunosuppression, and infections. A total of 20 recipients of SLKT were considered in the high immunological risk (HIR) group, and 68 recipients were included in the low immunological risk (LIR) control group. The prevalence of hepatitis C virus infection, second renal transplant, and time on dialysis prior to transplantation were significantly higher in the HIR group. The incidence of acute kidney rejection was higher in the HIR group (P<0.01). However, death-censored kidney graft survival as well as the estimated glomerular filtration rate at follow-up were not different between the 2 groups. Comorbidities, but not the immunological risk, impact negatively on patient survival. Despite the higher incidence of rejection in the HIR SLKT group, longterm renal function and graft survival were similar to the LIR group.

Rapid reduction of high-level pre-formed donor-specific antibodies after simultaneous liver-kidney transplantation: a report of two cases. BMC Nephrol 2020; 21:47. [PMID: 32050922 PMCID: PMC7014704 DOI: 10.1186/s12882-020-01714-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Accepted: 02/07/2020] [Indexed: 01/27/2023] Open
Abstract
Background Kidney transplantation performed in the presence of high-titre donor-specific antibodies (DSA) may result in hyper-acute or accelerated antibody-mediated rejection and rapid allograft loss. Previous studies have shown that this risk may be mitigated with simultaneous liver-kidney transplantation (SLKT); however, the mechanisms are not well defined. Here we report the evolution of pre-formed, high-level DSAs in two highly sensitised SLKT recipients peri-operatively and describe a profound sustained depletion of all DSAs from the time of liver anastomosis with no extra desensitisation therapy required. Case presentation Two patients underwent SLKT and received our centre’s standard renal transplant immunosuppression with basiliximab and methylprednisolone for induction therapy and prednisolone, mycophenolate and tacrolimus for maintenance therapy. HLA antibody samples were collected pre-operatively, and immediately post-liver and post-kidney revascularisation, and then regularly in the post-transplant period. Complement Dependant Cytotoxicity (CDC) crossmatches were also performed. Both patients were highly sensitised with a PRA over 97%. One patient had a positive B- and T-cell crossmatch pre-transplant. These positive CDC crossmatches became negative and the level of pre-formed DSAs reduced profoundly and rapidly, within 3 h post-liver revascularisation. The reduction in pre-formed DSAs, regardless of subclass, was seen immediately post-liver revascularisation, before implantation of the renal allografts. No significant reduction in non-donor specific HLA-antibodies was observed. Both patients maintained good graft function with no rejection on kidney allograft protocol biopsies performed at 10-weeks post-transplant. Conclusions These cases support the protective immunoregulatory role of the liver in the setting of SLKT, with no extra desensitisation treatment given pre-operatively for these highly sensitised patients.

Abstract
BACKGROUND Rejection remains the leading cause of allograft loss, and a major barrier to improving long-term outcomes after intestinal transplantation. 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. Standard induction immunosuppression was with interleukin-2 receptor antagonists, and antithymocyte globulin in high-risk recipients. Maintenance regimens were tacrolimus-based. RESULTS Pretransplant DSA was detected in 12 (11%) recipients with 50% continuing to have circulating antibodies posttransplant. An additional 24 (25%) patients developed de novo DSA, and of these, 71% had persistent antibodies. Recipients with preformed DSA demonstrated elevated risks of early graft failure, whereas those with de novo DSA experienced accelerated graft loss once DSA was detected, reaching a 28% failure rate within 2 years. HLA-DQ mismatch is a significant risk factor for de novo DSA emergence, whereas the persistence of antibodies is predicted by DSA strength and specificity. Although inclusion of the liver in the intestinal allograft imparts an immunological advantage against rejection-related graft loss, this protective effect was lost among recipients with persistent DSA. CONCLUSIONS The presence of DSA is associated with inferior graft outcomes among intestinal transplant recipients. An enhanced understanding of the mechanisms by which DSA causes allograft injury, and effective strategies targeting humoral immune reactivity are needed to improve long-term intestinal graft outcomes.

Abstract
BACKGROUND Combined kidney and auxiliary orthotopic liver transplantation from the same donor is used to treat highly sensitized renal transplant recipients. Auxiliary liver can protect the transplanted kidney against hyperacute rejection. METHODS In the current case, combined kidney and splenic fossa auxiliary heterotopic liver transplantation was performed from the same donor for a highly sensitized recipient without preoperative preconditioning. No postoperative hyperacute rejection occurred. RESULTS Seven days after surgery, preexisting antibody levels rose and decreased after treatment; meanwhile, the function of transplanted kidney returned to normal. During 24 months of follow-up, the grafts showed good blood perfusion and functioned well. The levels of preexisting antibodies, donor-specific antibodies (DSA) and C1q-fixing human leukocyte antigen (C1q-HLA) antibodies, all decreased. CONCLUSIONS Combined kidney and splenic fossa auxiliary heterotopic liver transplantation can be used in renal transplantation for highly sensitized recipients.

Abstract
Combined liver-kidney transplantation (CLKT) is well established as a definitive therapy with the potential to provide complete recovery for certain liver-kidney diseases, although the results might be contingent on the cause of transplantation. The purposes of the present study were to review the longterm outcome of renal allografts in CLKT patients from single living donors and to investigate the beneficial factors, compared with solitary renal transplantation. Thirteen patients underwent sequential liver transplantation (LT) and kidney transplantation (KT) from single living donors. The indications for KT were oxaluria (n = 7), autosomal recessive polycystic disease (n = 3), and others (n = 3). The same immunosuppressive regimen used after LT was also used after KT. KT was performed between 1.7 and 47.0 months after the LT. The overall patient survival rate was 92.3% at 10 years. In 12 of the 13 surviving patients, the renal allografts were found to be functioning in 11 patients after a mean follow-up period of 103.6 months. The death-censored renal allograft survival rate at 10 years was 100%, which was better than that of KT alone (84.9%) in Japan. Immunological protection conferred by the preceding liver allograft may have contributed to the longterm outcomes of the renal allografts. In addition, the donation of double organs from a single living and related donor may have a favorable impact on the graft survival rate. In the future, investigations of factors affecting the longterm outcome of renal allografts, including details of the involvement of de novo donor-specific antibody, will be needed.

Abstract
The results of simultaneous liver-kidney transplants in highly sensitized recipients have been controversial in terms of antibody-mediated rejection and kidney allograft outcomes. This case report provides a detailed and sophisticated documentation of histocompatibility and pathologic data in a simultaneous liver-kidney transplant performed in a recipient with multiple high-titered class I and II antidonor HLA antibodies and a strongly positive cytotoxic crossmatch. Patient received induction with steroids, rituximab, and eculizumab without lymphocyte depleting agents. The kidney transplant was delayed by 6 hours after the liver transplant to allow more time to the liver allograft to “absorb” donor-specific antibodies (DSA). Interestingly, the liver allograft did not prevent immediate antibody-mediated injury to the kidney allograft in this highly sensitized recipient. Anti-HLA single antigen bead analysis of liver and kidney allograft biopsy eluates revealed deposition of both class I and II DSA in both liver and kidney transplants during the first 2 weeks after transplant. Afterward, both liver and kidney allograft functions improved and remained normal after a year with progressive reduction in serum DSA values.

Abstract
The tolerogenic properties of the liver have long been recognised, especially in regard to transplantation. Spontaneous acceptance of liver grafts occurs in a number of experimental models and also in a proportion of clinical transplant recipients. Liver graft acceptance results from donor antigen-specific tolerance, demonstrated by the extension of tolerance to other grafts of donor origin. A number of factors have been proposed to be involved in liver transplant tolerance induction, including the release of soluble major histocompatibility (MHC) molecules from the liver, its complement of immunosuppressive donor leucocytes, and the ability of hepatocytes to directly interact with and destroy antigen-specific T cells. The large tissue mass of the liver has also been suggested to act as a cytokine sink, with the potential to exhaust the immune response. In this review, we outline the growing body of evidence, from experimental models and clinical transplantation, which supports a role for large tissue mass and high antigen dose in the induction of tolerance. We also discuss a novel gene therapy approach to exploit this dose effect and induce antigen-specific tolerance robust enough to overcome a primed T cell memory response.

Abstract
BACKGROUND We evaluated whether combined heart and liver transplant (H+LTx) can protect the heart graft from the development of cardiac allograft vasculopathy using coronary three-dimensional (3D) volumetric intravascular ultrasound (IVUS). METHODS From 2004 to 2009, we identified 24 isolated heart transplant (HTx) and 10 H+LTx recipients in whom two coronary 3D IVUS studies were performed 1 year apart. Baseline 3D IVUS was performed at 0.22 (0.17-1.16) years after transplantation, with follow-up 3D IVUS exams performed after baseline exam (0.96 [0.83-1.08]). RESULTS Rate of plaque volume and plaque index (plaque volume/vessel volume) progression was attenuated in the H+LTx group (0.3±1.1 vs. 1.5±2.9 mm/mm; P=0.08 and 0.01±0.03 vs. 0.1±0.1; P=0.004, respectively). Rejection burden was much lower in the H+LTx patients. Outcome analysis in 66 consecutive patients (56 HTx and 10 H+LTx) was performed irrespective of performance of second coronary IVUS. H+LTx was associated with reduced rate of cardiac events (P=0.04), which remained significant when adjusted for the difference in the primary etiology for heart disease (P=0.05). CONCLUSIONS Our preliminary serial 3D coronary IVUS data show that H+LTx attenuates cardiac allograft vasculopathy by decreasing the rate of plaque volume and plaque index progression and improves coronary-related outcomes. Because of the small numbers and the differences in etiology of heart disease, our data should be interpreted cautiously, and larger clinical trials would be required to recommend H+LTx for improved coronary remodeling.

Abstract
The role of antibodies in chronic injury to organ transplants has been suggested for many years, but recently emphasized by new data. We have observed that when immunosuppressive potency decreases either by intentional weaning of maintenance agents or due to homeostatic repopulation after immune cell depletion, the threshold of B cell activation may be lowered. In human transplant recipients the result may be donor-specific antibody, C4d+ injury, and chronic rejection. This scenario has precise parallels in a rhesus monkey renal allograft model in which T cells are depleted with CD3 immunotoxin, or in a CD52-T cell transgenic mouse model using alemtuzumab to deplete T cells. Such animal models may be useful for the testing of therapeutic strategies to prevent DSA. We agree with others who suggest that weaning of immunosuppression may place transplant recipients at risk of chronic antibody-mediated rejection, and that strategies to prevent this scenario are needed if we are to improve long-term graft and patient outcomes in transplantation. We believe that animal models will play a crucial role in defining the pathophysiology of antibody-mediated rejection and in developing effective therapies to prevent graft injury. Two such animal models are described herein.

Abstract
We simultaneously transplanted a liver and kidney (SLK) into a 55-year-old woman with end-stage liver disease secondary to recurrent primary biliary cirrhosis. The patient was blood group O, the donor was A(2) (A, non-A1) and the patient's A isoagglutinin titer was 512. Good renal function was evident by normalization of her creatinine values following transplantation. Recovery was unremarkable and she was discharged on post op day 9. The patient has not experienced an episode of rejection in either organ during the 6 months of follow-up. This case is important because high A IgG isoagglutinin levels (8 or higher) in kidney alone A(2) → O transplantation are detrimental to outcome but do not affect outcome in liver alone A(2) → O transplants; however, no such anti-A titer data have been published for A(2) → O (or B) SLK transplantation.

Abstract
For patients with chronic renal and liver diseases, simultaneous liver and kidney transplantation (SLKT) is the best therapeutic option. The role of a pretransplant donor-specific antibody (DSA) in SLKT is unclear. We report the results of a retrospective review from 7/08 to 10/09 of SLKT at our institution. Monitoring of DSA was performed using single antigen bead assay. Between 7/08 and 10/09, there were six SLKT who had preformed DSA and positive XM (four class I and II DSA, one class I DSA only, one class II only). One-year patient and renal graft survival was 83%. Death-censored liver allograft survival was 100%. Acute humoral rejection (AHR) of the kidney occurred in 66% (three with both class I and II DSA and one with only class II DSA) of patients. In those with AHR, class I antibodies were rapidly cleared (p < 0.01) while class II antibodies persisted (p = 0.25). All patients who had humoral rejection of their kidney had preformed anticlass II antibodies. Liver allografts may not be fully protective of the renal allograft, especially with pre-existing MHC class II DSA. Long-term and careful follow-up will be critical to determine the impact of DSA on both allografts.

Abstract
Hyperacute rejection of a transplanted liver is rare even when the recipient has circulating donor-specific alloantibodies (DSA). There is also evidence that a transplanted liver may provide immunological protection for other organs transplanted from the same donor. We monitored the kinetics of circulating DSA in a highly sensitized recipient of a combined split liver and kidney transplant and demonstrated a reduction in antibody titres immediately after liver perfusion. The absorption of DSA was not compromised by the smaller liver mass transplanted. DSA titres remained low at 3 months post-transplant, and the recipient did not experience antibody-mediated rejection.

Abstract
With advancements in the operative techniques, patient survival following liver transplantation (LTx) has increased substantially. This has led to the acceleration of pre-existing kidney disease because of immunosuppressive nephrotoxicity making additional kidney transplantation (KTx) inevitable. On the other hand, in a growing number of patients on the waiting list to receive liver, long waiting time has resulted in adverse effect of decompensated liver on the kidney function. During the last two decades, the transplant community has considered combined liver kidney transplantation (CLKTx) to overcome this problem. The aim of our study is to present an overview of our experience as well as a review of the literature in CLKTx and to discuss the controversy in this regard. All performed CLKTx (n = 22) at our institution as well as all available reported case series focusing on CLKTx are extracted. The references of the manuscripts were cross-checked to implement further articles into the review. The analyzed parameters include demographic data, indication for LTx and KTx, duration on the waiting list, Model for End-Stage Liver Disease (MELD) score, Child-Turcotte-Pugh (CTP) score, immunosuppressive regimen, post-transplant complications, graft and patient survival, and cause of death. From 1988 to 2009, a total of 22 CLKTx were performed at our institution. The median age of the patients at the time of CLKTx was 44.8 (range: 4.5-58.3 yr). The indications for LTx were liver cirrhosis, hyperoxaluria type 1, polycystic liver disease, primary or secondary sclerosing cholangitis, malignant hepatic epithelioid hemangioendothelioma, cystinosis, and congenital biliary fibrosis. The KTx indications were end-stage renal disease of various causes, hyperoxaluria type 1, polycystic kidney disease, and cystinosis. The mean follow-up duration for CLKTx patients were 4.6 +/- 3.5 yr (range: 0.5-12 yr). Overall, the most important encountered complications were sepsis (n = 8), liver failure leading to retransplantation (n = 4), liver rejection (n = 3), and kidney rejection (n = 1). The overall patient survival rate was 80%. Review of the literature showed that from 1984 to 2008, 3536 CLKTx cases were reported. The main indications for CLKTx were oxalosis of both organs, liver cirrhosis and chronic renal failure, polycystic liver and kidney disease, and liver cirrhosis along with hepatorenal syndrome (HRS). The most common encountered complications following CLKTx were infection, bleeding, biliary complications, retransplantation of the liver, acute hepatic artery thrombosis, and retransplantation of the kidney. From the available data regarding the need for post-operative dialysis (n = 673), a total of 175 recipients (26%) required hemodialysis. During the follow-up period, 154 episodes of liver rejection (4.3%) and 113 episodes of kidney rejection (3.2%) occurred. The cumulative 1, 2, 3, and 5 yr survival of both organs were 78.2%, 74.4%, 62.4%, and 60.9%, respectively. Additionally, the cumulative 1, 2, 3, and 5 yr patient survival were 84.9%, 52.8%, 45.4%, and 42.6%, respectively. The total number of reported deaths was 181 of 2808 cases (6.4%), from them the cause of death in 99 (55%) cases was sepsis. It can be concluded that there is still no definitive evidence of better graft and patient survival in CLKTx recipients when compared with LTx alone because of the complexity of the exact definition of irreversible kidney function in LTx candidates. Additionally, CLKTx is better to be performed earlier than isolated LTx and KTx leading to the avoidance of deterioration of clinical status, high rate of graft loss, and mortality. Shorter graft ischemia time and more effective immunosuppressive regimens can reduce the incidence of graft malfunctioning in CLKTx patients. Providing a model to reliably determine the need for CLKTx seems necessary. Such a model can be shaped based upon new and precise markers of renal function, and modification of MELD system.

Abstract
A significant number of patients awaiting liver transplantation have associated renal failure and renal dysfunction is associated with increased morbidity and mortality after LT. There has been a recent increase in the number of CLKT in adults. The common indications for CLKT in children are different from those of adults and include metabolic diseases affecting the kidney with or without liver dysfunction and congenital developmental abnormalities affecting both organs. The results are generally encouraging among these groups of patients. Early evaluation and listing of patients before they become severely ill or have major systemic manifestations of their metabolic problem are important.

Abstract
Combined liver-kidney transplantation has become a common practice for the treatment of patients with concurrent end-stage renal disease and end-stage liver disease. Liver transplantation in the setting of multiorgan transplantation is thought to have a protective effect against humoral rejection even when a positive crossmatch is obtained prior to surgery. In most centers, a pre liver-kidney transplant crossmatch is rarely performed because of the known immunoprotective effect of the liver allograft. In this report, a case of acute humoral rejection in the kidney allograft after a combined liver-kidney transplant is described. Although humoral rejection was treated using plasmapheresis, intravenous immunoglobulin and rituximab, the kidney required 3 months to recover function and finally progressed to chronic allograft nephropathy. A heightened index of suspicion for acute humoral rejection of the renal allograft is necessary when performing combined liver-kidney transplants to highly sensitized patients due to previous organ transplants.

Abstract
UNLABELLED A significant number of patients awaiting liver transplantation have associated renal failure. Combined Liver and Kidney Transplantation (CLKT) is increasingly offered especially since the introduction of Model for End-Stage Liver Disease (MELD). Decision to perform CLKT is straightforward when both organs suffer end-stage failure. However, the indications for CLKT are not well defined and there is controversy concerning some. We reviewed available data on PUBMED, United Network for Organ Sharing (UNOS), Organ Procurement Transplantation Network (OPTN), European Society for Organ Transplantation (ESOT) and discuss all current indications for CLKT. CONCLUSION Overall long-term outcome following CLKT is acceptable. There is an urgent need to further refine our ability to identify the cases with reversible renal injury in the setting of end-stage liver disease to avoid unnecessary CLKT. Liver protects the kidney from disease recurrence and allograft loss in metabolic diseases. However, the use of liver allograft for immunological protection of kidneys in highly sensitised patients with positive cross-match and previously failed renal transplants is still experimental.

Abstract
Combined liver-kidney transplantation is considered a low risk for immunologic complication. We report an unusual case of identical ABO liver-kidney recipient without preformed anti-human leukocyte antigen (HLA) antibodies, transplanted across a T- and B-cell-negative cross-match and complicated by early acute humoral and cellular rejection, first in the liver then in the kidney. While analyzing the immunologic complications in our cohort of 12 low-risk combined liver-kidney recipients, only one recipient experienced a rejection episode without detection of anti-HLA antibody over time. Although humoral or cellular rejection is rare after combined kidney-liver transplantation, our data suggest that even in low-risk recipients, the liver does not always systematically protect the kidney from acute rejection. Indeed, the detection of C4d in the liver should be carefully followed after combined liver-kidney transplantation.

Abstract
Acute renal failure (ARF) is common immediately after orthotopic liver transplantation (OLT), whereas the incidences of chronic kidney disease (CKD) and end-stage renal disease increase with time. Introduction of the Model for End-stage Liver Disease (MELD) score-intended to prioritize patients with more-severe pretransplantation liver disease in general, and worse pretransplantation renal function in particular-for the allocation of liver grafts led to concerns about compromised patient and allograft survival and increased incidence of postoperative ARF and CKD. Nonetheless, it has been suggested that early OLT of candidates with baseline renal dysfunction improves post-transplantation renal outcomes. For OLT candidates with mild to moderate chronic renal impairment or recent-onset ARF, the decision of whether to perform OLT alone or combined liver-kidney transplantation (CLKT) can be challenging because no single factor has been shown to be predictive of the degree of renal function recovery or CKD progression following successful OLT. In this article, we provide an overview of the literature on renal function outcomes following OLT and CLKT, share our perspectives on the potential predictors of renal dysfunction or nonrecovery of renal function after OLT, and present United Network for Organ Sharing data on patient and allograft outcomes in CLKT recipients in the pre-MELD and post-MELD eras. Mechanisms that might underlie immunological protection of kidney grafts by liver allografts are also discussed.

Abstract
Combined liver and renal transplantations can be performed against a positive cross-match, indicating that the liver protects the kidney from the harmful HLA antibodies. This led us to the hypothesis that a partial auxiliary liver graft may have a similar protective effect when performed together with the kidney in highly sensitized patients. Seven patients, with broadly reacting HLA antibodies and positive crossmatches, were transplanted with a partial liver and a kidney from the same donor. In one of the cases a living donor was used. We performed lymphocytotoxic and flow cross-matches before and after the transplantation. Cross-matches turned negative after grafting in five of seven cases. The kidney function was excellent, without rejections, during the follow-up (24-60 months) in these patients. In two cases the cross-match remained positive after transplantation, one with a never-functioning renal graft and the other with an early graft failure, probably due to humoral rejection. A simultaneous transplantation of a partial auxiliary liver graft from the same donor, with the sole purpose of protecting the kidney from harmful lymphocytotoxic antibodies, can be performed successfully despite a positive cross-match and may thus be a new option of treatment for highly sensitized patients waiting for a kidney transplant.

Abstract
ABO-incompatible (ABO-I) liver transplantation is a controversial issue because of the generally less favorable outcome as compared to compatible transplants. Encouraging results have been shown by the introduction of new strategies to reduce posttransplant-specific hemagglutinin (HA) titers with plasmapheresis, reinforced immunosuppression (IS), and the use of splenectomy. We describe a new protocol consisting of daclizumab (DAC) induction, mycophenolate mofetil (MMF)/tacrolimus (TAC)/steroids without splenectomy. Five recipients (mean age of 47 +/- 14 yr) undergoing ABO-I living donor liver transplantation (LDLT) were included in this protocol. Immunoadsorbent columns (Glycosorb ABO) were used for antigen-specific immunoadsorption (ASI). The median follow-up was 18.5 +/- 10.5 months. ASI was very efficient in lowering HA titers (mean log(2) immunoglobulin [Ig] M [IgM] and IgG values before and after ASI were 5.9 +/- 2.8 and 1.2 +/- 1.4 [P= 0.0038] and 6.5 +/- 2.3 and 1.1+/- 1.9, respectively [P= 0.0001]). Persisting low HA titers were observed over time. No sepsis nor cytomegalovirus infection episodes were recorded. Acute cellular rejection (ACR) occurred in 1 recipient responding to steroid pulse therapy. Two grafts were lost in 2 patients due to technical failure during the first postoperative month. We conclude that ASI using Glycosorb ABO, quadruple immunosuppression including DAC and MMF provide high efficiency to lower HA titers over time, avoiding the need for splenectomy. ABO-I LDLT can be performed with this adapted IS protocol.

Abstract
Combined liver kidney transplantation (LKT) has the potential to provide a complete recovery of liver and kidney failure; the literature reports an increase in LKT in the last few years and an improvement in patient and graft survival. In our experience 15 patients underwent LKT from 1997 to 2005. The mean age was 50 +/- 9 years (range 34 to 63). The patients were affected by viral (n = 9), alcoholic (n = 1), polycystic (n = 2), cholangitis (n = 1), cholestatic (n = 1), or amyloidotic (n = 1) chronic hepatopathy. Chronic renal failure (CRF) was due to polycystic kidney disease (n = 4), IgA (n = 2), interstitial nephropathy (n = 2), glomerulonephritis (n = 4), amyloidosis (n = 1), vascular nephropathy (n = 1), of unknown end-stage renal disease (n = 1). Twelve of 15 patients were on renal dialysis treatment, three patients had moderate/severe CRF. Two patients had previously been transplanted (kidney). All patients were selected based upon blood group identity and negative cross-match before kidney transplant. Histocompatibility matching (HLA) was not included in the selection criteria. We did not observe delayed graft function. After a mean follow-up was 23 +/- 32 months (range 5 to 99), 12 subjects show, normal hepatic and renal function. At the beginning of our experience two patients in bad clinical condition died within 3 months because of sepsis, and one died because of a malignancy after 7 years. Both organs were functioning well in the deceased patients. Survival analysis confirms LKT efficacy: at 5 years follow-up patient survival is 86%, graft survival censored for death 100%. Only two subjects had an acute rejection episode in the first year; the kidney rejection incidence was lower than that reported for an isolated kidney transplant (13% vs 21%).

Abstract
A pretransplant positive cross-match is a contraindication for kidney transplantation, unlike in liver transplantation (OLT). In combined liver kidney transplantation (LKT) it is hypothesized that liver can protect kidney from rejection. We report the case of a 35-year-old woman on renal replacement therapy with gastrointestinal tract compression due to a hematoma following spontaneous liver rupture (May 2004). She was affected by amyloidosis, treated with a bone marrow autotransplantation (2001). The liver rupture was surgically untreatable, so an LKT was proposed. Panel-reactive antibody was 80% to 100% (complement dependent cytotoxicity) with specific anti-HLA antibodies (enzyme-linked immunosorbent assay). A compatible donor was found (July 2004). The cross-match before LKT was positive for B and T cells (score 8): an emergency OLT was performed. Immediately after liver reperfusion the cross-match result was less positive (6) for T cells. After 6 hours it was negative for T and slightly positive for B cells (4): the kidney was transplanted. The immunosuppressive therapy was: alemtuzumab, steroids, and tacrolimus. Renal function immediately recovered. On day 7 a rejection episode was successfully treated by increasing steroids (intravenous bolus). At discharge hepatic and renal function were normal (creatinine 1 mg/dL). They are stable after 1 year. This case showed LKT efficacy even in complex immunological situations. Many immunological mechanisms, still not defined, are hypothesized about the protective role of the liver. This case confirmed experimental data that highlighted that in vivo in humans a cross-match can change from positive to negative after OLT giving highly sensitized patients the possibility for LKT.

Abstract
Human leukocyte antigen G (HLA-G) is a regulatory molecule that is expressed in the cytotrophoblast during implantation and is thought to allow the tolerance and the development of the semiallogeneic embryo. In vitro, HLA-G inhibits natural killer (NK) cell and CD8 T-cell cytotoxicity. HLA-G also decreases CD4 T-cell expansion. This suggests that it participates in the acceptance of allogeneic organ transplants in humans. We here describe the detection of high concentration of HLA-G in serum from liver-kidney transplant patients, but not in kidney transplant patients. This finding is supported by the ectopic expression of HLA-G in graft biopsies. Finally, its association with a low number of acute transplant rejections, especially in liver-kidney transplant patients led us to propose that HLA-G may serve to monitor transplant patients who are likely to accept their allograft and, thus, may benefit of a reduced immunosuppressive treatment.

Abstract
BACKGROUND/AIMS Liver allograft is known to protect simultaneously transplanted organs from acute rejection. We have reported that only 6% of combined liver-kidney recipients, versus 32.5% of kidney recipients, develop kidney graft acute rejection. Release of soluble human leukocyte antigen (HLA) molecules by the liver has been proposed as a possible tolerogenic mechanism involved in the better acceptance of double transplants. The HLA-G molecule is acknowledged to possess tolerogenic properties. METHODS We investigated the involvement of HLA-G in allogeneic transplant acceptance by analyzing its expression in kidney and liver biopsies of 40 combined transplanted patients. RESULTS We demonstrate the presence of HLA-G in 14 out of 40 liver and five out of nine kidney transplants biopsies. HLA-G is expressed de novo by cells that are otherwise frequently susceptible target cells of acute rejection, i.e. liver biliary and renal tubular epithelial cells. We show a significant association between HLA-G expression in liver biliary epithelial cells and the absence of liver graft rejection. No acute or chronic rejection of the kidney graft was observed in patients in whom HLA-G was expressed in the liver graft. CONCLUSIONS HLA-G expression in the liver allograft is associated with a lower frequency of hepatic and renal acute rejection and may be involved in the acceptance of simultaneously transplanted organs.

Abstract
Experience with combined liver-kidney transplantation (L-KTx) has increased, but controversy regarding this procedure continues because the indications are not clearly defined yet. Between 1984 and 2000, 38 patients underwent simultaneous L-KTx and 9 patients underwent sequential transplantation, receiving either a liver before a kidney or a kidney before a liver. Main indications for a simultaneous procedure were polycystic liver-kidney disease with cirrhosis and coincidental renal failure. The main indications for sequential procedure were cirrhosis caused by viral infection for the liver and glomerulonephritis for the kidneys. Outcomes in these patients were evaluated retrospectively. Regarding simultaneous transplantation, 28 (73.7%) long-term survivors were followed up for 0.7 to 12.5 years. Currently, 24 (63.2%) patients are alive with good liver function. Fourteen patients died; 10 patients died in the early postoperative phase because of septic complications, and most of them were cirrhotic with a poor preoperative clinical status. Currently, 2 of the surviving patients (8%) have returned to dialysis, 4 (17%) have reduced renal function, and 18 (75%) have good renal function. Five liver and 2 kidney retransplantations were performed during the follow-up. In cases of sequential grafting, patients undergoing kidney transplantation in the presence of a previously transplanted stable liver did better than those who underwent liver transplantation after kidney transplantation. When liver transplantation was performed early and electively before substantial worsening, combined L-KTx is a safe procedure offering excellent long-term palliation.

Abstract
In the case of coexisting abdominal aortic aneurysm (AAA) and liver/renal failure, the controversial issue is the timing of the AAA repair and the transplantation of the affected organs. The question is whether to repair the AAA first and perform the double transplantation at a later time, or to perform all three procedures in the same operative session. This patient was affected by hepatic/renal failure and had also developed AAA. We describe the operative strategies utilized to perform the cadaver donor and recipient operations in this setting. In our patient, a combined liver/kidney transplantation with simultaneous aneurysm repair using arterial allografts was successfully performed. In a patient affected by end-stage liver, kidney, and aneurysmatic disease, a simultaneous liver/kidney transplant and AAA repair may represent the safest and most efficient treatment solution.

Abstract
Multiple organ transplantations are used to treat chronic multiple organ failure. However, long-term mortality and graft tolerance remain to be evaluated. We carried out a retrospective and comparative analysis of 45 patients who underwent a combined liver and kidney (LK) transplantation (LKT) from the same donor. They were compared to 86 matched patients who underwent kidney (K) transplantation (KT). All patients had an organic renal failure associated with cirrhosis (n = 35) or with inherited disease (n = 10). Nineteen (42.9%) had been transplanted previously. The patients' survival rate was 85% at 1 year and 82% at 3 years. Seven patients died within the first 3 months, due to severe polymicrobial infection. Two patients in the LK population (4.2%) developed acute rejection of the kidney graft compared to 24 of the 86 matched renal transplanted patients (32.6%). In parallel, acute liver rejection was observed in 14 cases (31.1%) in the LK population. The occurrence of acute rejection was not associated with panel-reactive lymphocytotoxic antibodies (n = 16), nor with positive cross-matches (n = 3). Four of the 45 patients (8.8%) subsequently developed chronic renal allograft rejection, and 16 cases of chronic hepatic dysfunction were noted (42.2%). In conclusion, the overall survival rate following combined liver kidney transplantation is acceptable, and LKT can be proposed to patients with kidney failure associated with liver dysfunction, primary oxaluria or amyloid neuropathy. The main cause of mortality in this population was severe infectious complications. The frequency of acute kidney rejection was lower than in single transplantation.

Abstract
Liver-kidney transplantation (LKT) should be reserved for those recipients with primary disease affecting both organs. However, increasing transplant list waiting times have increased the development and duration of acute renal failure before liver transplantation. Furthermore, the need for posttransplant calcineurin inhibitors can render healing from acute renal failure difficult. Because of the increasing requests for and controversy over the topic of a kidney with a liver transplant (OLT) when complete failure of the kidney is not known, the following article will review the impact of renal failure on liver transplant outcome, treatment of peri-OLT renal failure, rejection rates after LKT, survival after LKT, and information on renal histology and progression of disease into the beginnings of an algorithm for making a decision about combined LKT.

Abstract
Many liver transplant recipients are now reaching survival beyond 5 years from the liver transplant procedure, and many others are alive more than a decade from acquiring their new liver. Orthotopic liver transplant recipients enjoy the benefits of normal liver function, but a variety of metabolic and other medical problems often develop that require diagnosis and adequate management. These problems include hyperlipidemia, obesity, diabetes mellitus, renal disfunction, arterial hypertension, bone disease and neuropsychiatric syndromes. The gastroenterologist, internist, or local family physician is frequently called on to identify and treat these postoperative complications in conjunction with physicians at the transplant center.
