Multiple studies during the past decades have identified chronic liver disease as an important cause of morbidity and mortality in kidney transplant recipients. It has been reported that up to 25% of patients will have some degree of abnormal liver functions during the immediate posttransplant period. In these patients, liver failure has been implicated as the cause of death in approximately 30% of the long-term survivors. While infections from hepatitis virus remain the main cause of ongoing liver damage, many other opportunistic infections with various potential to alter liver function have also been identified. In addition, posttransplant patients are also exposed to hepatotoxic adverse effects of many pharmacotherapeutics including immunosuppressive and nonimmunosuppressive agents. Since there are numerous reports dealing with classic viral hepatitis after kidney transplantation, this review primarily focuses on post-kidney transplant liver diseases which are not due to classic hepatitis viruses.

Bilirubin adsorption column Medisorba BL-300 (Kuraray Medical Inc.) for the treatment of hyperbilirubinemia is introduced. The adsorbent packed in this column is the porous anion exchange resin coated with hydrophilic 2-hydroxyethyl methacrylate copolymer in order to improve blood compatibility. The adsorbent showed a high adsorption rate for direct bilirubin and indirect bilirubin in patient plasma in vitro. This column is used in plasmaperfusion therapy in clinical use. BL-300 showed high removal rate for direct bilirubin, indirect bilirubin and bile acid in clinical evaluation. BL-300 is approved in Japan and it has been used for the treatment of hyperbilirubinemia caused by many diseases such as liver failure and hepatitis.

Acute thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder that has previously been described associated with various types of surgery. An association between total abdominal hysterectomy (TAH) and TTP has never been reported. Thrombotic thrombocytopenic purpura is classically characterized by thrombocytopenia, microangiopathic hemolytic anemia, fever, azotemia and neurological manifestations. Atypical manifestations of TTP include hepatitis, pancreatitis, acute respiratory distress syndrome, non-occlusive mesenteric ischemia and peripheral digital ischemia. This case report describes the occurrence of acute TTP following TAH and bilateral salpingo-oopherectomy, which manifested with typical and atypical features (i.e. hepatitis, pancreatitis). Plasma exchange therapy resulted in the complete resolution of the process.

The most important transplantation antigen system for organ transplantation is the ABO blood group system. Crossing the blood barrier is usually not done except in emergency cases such as liver transplantations for fulminant hepatitis. Early experiences of allograft transplantations across the blood barriers were discouraging. In the 1970s, clinical trials were started transplanting kidneys of subgroup A2 into blood group O recipients because the tissues of the A2 subgroup express a lower amount of A antigens compared with subgroup A1. The recipients required no special treatment and received the standard immunosuppressive regimen as used in blood group identical cases. Many early graft loses immediately after transplantations were experienced, but these trials resulted in an excellent graft survival rate. A few centers have adapted the concept of A2 kidneys to non-A recipient transplantations with successful results by reducing anti-A blood type titers prior to transplantations. In the early 1980s, the possibility of bridging the ABO barrier was tested by several groups. A1 and B kidneys from living donors were also successfully transplanted across the blood barrier using quadruple immunosuppressive drugs and splenectomy. Since 1989, the largest number of ABO-incompatible renal transplantations have been performed in Japan because of the limited numbers of cadaveric donors. Approximately 400 cases have been successfully transplanted across the blood barrier at many centers in Japan. Owing to novel immunosuppressive drugs, the ABO-incompatible allografts exhibited a level of function comparable with that of ABO-matched allografts even though anti-A or anti-B antibodies had returned to the circulation of the recipients. In this article, we describe the historical background, the current therapeutic strategies including apheresis therapy for the ABO-incompatible transplantations, and the experiences at our institution.

We developed a series-parallel treatment method for combined plasma exchange (PE) and continuous hemodiafiltration (CHDF) therapy in fulminant hepatitis. We then compared total serum bilirubin, citrate, and cytokine levels obtained by the new methods to those obtained with treatment by the single and reverse-parallel PE methods. Ten adult patients with fulminant hepatitis consented to participate. Plasma exchange was conducted 25 times by the single method (PE only), 16 times by the reverse-parallel method, and 37 times by the series-parallel method. The percentage of total bilirubin removed was highest with the single method followed in order by that with the series-parallel and reverse-parallel methods; the differences were significant. The percentage increase in citrate level was highest with the single method, followed in order by that with the series-parallel and the reverse-parallel methods; these differences were also significant. There was no significant difference in serum interleukin (IL)-6 levels after PE, by the single or the reverse-parallel methods. However, the IL-6 level decreased significantly following PE by the series-parallel method. The serum IL-18 level decreased significantly following PE by each of the three methods. Thus, removal of excess bilirubin, citrate, and cytokines by the series-parallel method, a simple maneuver with excellent removal rates, was considered effective.

Severe viral hepatitis with high mortality is the most common cause of liver failure in China. Treatment of severe viral hepatitis by hemoperfusion was initially adopted in the late 1970s and early 1980s. Following 10 years of development in China, a plasma exchange (PE)-centered artificial liver support system (ALSS), principally dependent on PE technology was developed. Based on the condition and symptoms of each patient, PE was given alone, or combined with hemodialysis, hemofiltration, hemodiafiltration, hemoperfusion, or plasma perfusion. In the late 1990s, training courses for ALSS were developed, and ALSS began to be carried out across China. Guidelines for artificial liver therapy were formulated and published by the Artificial Liver and Liver Failure Group of the Chinese Society of Infection. In recent years, new methods have been attempted, including small pore-size plasma separators, a molecular adsorbent-based recirculating system (MARS), and a continuous albumin purification system (CAPS). According to a retrospective analysis published in 2004, ALSS therapy significantly (P < 0.001) improved the survival rate of patients with severe hepatitis compared with patients who received only medicines (43.4%, 157/362 vs. 15.4%, 55/358 in chronic patients and 78.9%, 30/38 vs. 11.9%, 5/42 in acute and subacute patients). Furthermore, ALSS has also proved valuable as a bridge to liver transplantation in the treatment of patients with end-stage severe hepatitis in China. More recently, ALSS has been used in the treatment of drug-induced liver failure, acute fatty liver during pregnancy, and other difficult-to-treat disorders in China.

A 60-year-old male with cerebral infarction was admitted to our hospital and treated with edaravone. On day 12 of hospitalization, he suddenly lost consciousness and went into shock. Based on the laboratory findings, acute renal failure (ARF), fulminant hepatitis, and disseminated intravascular coagulation (DIC) were diagnosed. We immediately initiated continuous hemodiafiltration for three days and performed three sessions of plasma exchange. Following this, a gradual improvement was observed in the patient's general condition and laboratory values. On day 17 of hospitalization, intermittent hemodialysis (HD) was initiated. On day 20 of hospitalization, his renal function started to improve with an increase in urine volume. HD was successfully discontinued on the same day. Although the drug lymphocyte stimulation test for edaravone was negative, edaravone-induced fulminant hepatitis was suggested based on liver biopsy findings. We present a case of ARF, fulminant hepatitis, and DIC due to edaravone administration that was successfully treated with blood purification techniques. Since the use of edaravone treatment is expected to increase in the future, it is essential that clinicians consider the potential adverse effects of this treatment. It is suggested that blood purification is effective in inducing remission in patients with complications due to edaravone treatment.

Plasma diafiltration (PDF) is blood purification therapy in which simple plasma exchange is performed with a membrane plasma separator while dialysate flows outside the hollow fibers. A 14-year-old boy with fulminant hepatitis underwent two sessions of PDF and one session of hemodiafiltration. We infused filtered replacement fluid for artificial kidneys at a dialysate flow rate of 600 mL/h and a replacement flow rate of 450 mL/h. We infused fresh frozen plasma (1200 mL) and 25% albumin solution (50 mL) intravenously over 8 h. Each PDF session lasted 8 h. The patient's total bilirubin, interleukin-18, and cystatin C levels decreased with treatment, and he recovered from hepatic failure. PDF may be an extremely useful blood purification therapy for pediatric fulminant hepatitis in terms of both medical economics and cytokine removal.

The aim of this study was to evaluate the improvement of prognostic parameters after treatment with the molecular adsorbent recirculating system (MARS) in patients with fulminant hepatitis (FH). The parameters conducive to a positive prognosis include: Glasgow Coma Scale (GCS) score >/=11, intracranial pressure (ICP) <15 mm Hg or an improvement of the systolic peak flow of 25-32 cm/s via Doppler ultrasound in the middle cerebral artery, lactate level <3 mmol/L, tumor necrosis factor-alpha <20 pg/mL, interleukin (IL)-6 <30 pg/mL, and a change in hemodynamic instability from hyperkinetic to normal kinetic conditions, and so define the timing (and indeed the necessity) of a liver transplant (LTx). From 1999 to 2008 we treated 45 patients with FH with MARS in the intensive care unit of our institution. We analyzed all the parameters that were statistically significant using univariate analysis and considered the patients to be candidates for inclusion in a multivariate logistic regression analysis. Thirty-six patients survived: 21 were bridged to liver transplant (the BLT group) and 15 continued the extracorporeal method until native liver recovery (the NLR group) with a positive resolution of the clinical condition. Nine patients died before transplantation due to multi-organ failure. We stratified the entire population into three different groups according to six risk factors (the percentage reduction of lactate, IL-6 and ICP, systemic vascular resistance index values, GCS <9, and the number of MARS treatments): group A (0-2 risk factors), group B (3-4 risk factors), and group C (5-6 risk factors). Analyzing the prevalence of these parameters, we noted that group A perfectly corresponded to the NLR group, group B corresponded to the BLT group, and group C was composed of patients from the non-survival group; thus, we were able to select the patients who could undergo a LTx using the predictive criteria. For patients with an improvement of neurological status, cytokines, lactate, and hemodynamic parameters, LTx was no longer necessary and their treatment continued with MARS and standard medical therapy.

Plasma diafiltration (PDF) is a blood purification therapy in which simple plasma exchange (PE) is performed using a selective membrane plasma separator while the dialysate flows outside the hollow fibers. A prospective, multicenter study was undertaken to evaluate the changes in bilirubin, IL-18, and cystatin C, as well as the 28-day and 90-day survival rates, with the use of PDF according to the level of severity as measured by the Model for End-Stage Liver Disease (MELD) score. Twenty-one patients with liver failure were studied: 10 patients had fulminant hepatitis and PDF therapies were performed 28 times; 11 had acute liver failure with the therapy performed 96 times. Levels of total bilirubin, IL-18, and cystatin C decreased significantly after treatment. The 28-day survival rate was 70.0% and that at 90 days was 16.7%. According to the severity of the MELD score, each of the results compared well with the use of Molecular Adsorbent Recirculating System or Prometheus therapy. In conclusion, PDF appears to be one of the most useful blood purification therapies for use in cases of acute liver failure in terms of medical economics and the removal of water-soluble and albumin-bound toxins.
