Interleukin-2 receptor antagonists for pediatric liver transplant recipients: a systematic review and meta-analysis of controlled studies.

IL-2RA are frequently used as induction therapy in liver transplant recipients to decrease the risk of AR while allowing the reduction of concomitant immunosuppression. The exact association with the use of IL-2RA, however, is uncertain. We performed a systematic literature search for relevant studies.

Erythropoietin rs1617640 G allele associates with an attenuated rise of serum erythropoietin and a marked decline of hemoglobin in hepatitis C patients undergoing antiviral therapy.

Background: A decline in hemoglobin (Hb) concentration during antiviral therapy in chronic hepatitis C (CHC) is a serious side effect. It may compel to dose reduction or even termination of antiviral treatment. The activation of erythropoietin (EPO) synthesis as a physiological response to anemia and its relation to a genetic variation within the EPO gene has not been evaluated yet.

Treatment of chronic HCV genotype 1 infection with telaprevir: a Bayesian mixed treatment comparison of fixed-length and response-guided treatment regimens in treatment-naïve and -experienced patients.

Background: Telaprevir (TVR) has been approved for response-guided-therapy (RGT) of chronic hepatitis C (HCV) genotype-1-infection in treatment-naïve and -experienced patients. In RGT-regimens patients that did not achieve extended rapid-virological-response (eRVR) within the first 4-12 weeks undergo treatment for 48-weeks, whereas in fixed-length-treatment (FLT) patients are treated for a fixed-duration regardless of their RVR.

Methods: This systematic review and Bayesian mixed-treatment-comparison (MTC) aimed to compare the efficacy and safety of standard-therapy with pegylated-interferon-α/ribavirin (Peg-IFN-α/RBV (48 weeks), group A), FLT with TVR, Peg-IFN-α/RBV for 12 weeks with a long (+36 weeks, group B) or short (+12 weeks, group C) tail of Peg-IFN-α/RBV treatment, and RGT with 12 weeks of TVR, Peg-IFN-α/RBV followed by 12 weeks of Peg-IFN-α/RBV (group D) or no therapy (group E).

Vitamin D status and serum ferritin concentration in chronic hepatitis C virus type 1 infection.

The circulating 25-hydroxylated form of vitamin D(3), 25(OH)D, and serum ferritin concentrations have been described to be associated with disease progression in chronic hepatitis C. Both parameters also have been assessed with regard to treatment outcome, however, with divergent results. This study examined both the pre- and posttreatment serum concentrations of 25(OH)D and ferritin in 191 patients infected chronically with hepatitis C virus (HCV) type 1 with regard to liver inflammatory activity (grading), disease progression in terms of fibrosis (staging) and an antiviral treatment outcome.

Liver transplantation in patients with liver cirrhosis and active pneumonia: an observational study.

Patients with chronic liver disease are at high risk for severe infection because of increased bacterial translocation and immune suppression associated with liver dysfunction. Patients presenting with severe pneumonia and acute decompensation of cirrhosis are generally not considered for liver transplantation because it is unknown if these patients can recover from infection while under immunosuppression. We performed an observational study where patients with cirrhosis of the liver remained on the waiting list, although suffering from active pneumonia.

Interleukin 2 receptor antagonists for liver transplant recipients: a systematic review and meta-analysis of controlled studies.

Unlabelled: Interleukin 2 receptor antagonists (IL-2Ra) are frequently used as induction therapy in liver transplant recipients to decrease the risk of acute rejection while allowing the reduction of concomitant immunosuppression. We conducted a systematic review of prospective, controlled studies to test the hypothesis that the use of IL-2Ra is associated with a decrease in acute rejection and/or a decrease in the side effects of concomitant medication. We performed a search of all major databases and secondary sources from inception to December 2010.

Posterior cavoplasty: a new approach to avoid venous outflow obstruction and symptoms for small-for-size syndrome in right lobe living donor liver transplantation.

Purpose: A common and serious problem after living donor liver transplantation (LDLT) of small grafts is small-for-size syndrome (SFSS). Although hyperdynamic portal inflow and portal hypertension are cornerstones in the development of SFSS, inadequate outflow may aggravate SFSS. Therefore, enlargement of the portal outflow tract by incision of the anterior rim of the orifice of the right hepatic vein (RHV) has been advocated for right lobe LDLT.

Tissue damage with different surgical techniques in a porcine model of liver resection: implications for living-donor liver transplantation?

Background/purpose: For living-donor liver transplantation (LDLT) it is of paramount importance to preserve as much viable liver tissue as possible to avoid postoperative complications in the donor and recipient. The depth of tissue damage caused by common surgical techniques for liver resection has not been studied so far.

Methods: Here we compared the depth of tissue damage and the immunohistochemical expression of heat shock protein (HSP) 70, a marker for tissue damage, in a porcine model of liver resection, to assess the effect of different surgical techniques, i.

A therapeutic exploratory study to determine the efficacy and safety of calcineurin-inhibitor-free de-novo immunosuppression after liver transplantation: CILT.

Background: Immunosuppression with calcineurin inhibitors (CNI) increases the risk of renal dysfunction after orthotopic liver transplantation (OLT). Controlled trials have shown improvement of renal function in patients that received delayed and/or reduced-dose CNI after OLT. Delaying immunosuppression with CNI in combination with induction therapy does not increase the risk of acute rejection but reduces the incidence of acute renal dysfunction.

Acute paranoid psychosis as sole clinical presentation of hepatic artery thrombosis after living donor liver transplantation.

Background: Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications.

Adult Living Donor Liver Transplantation with ABO-Incompatible Grafts: A German Single Center Experience.

Adult living donor liver transplantations (ALDLTs) across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies.

Fourteen-year survival of a renal graft reused 2 years after initial transplantation: a case report.

We report on the successful regrafting of a transplanted kidney. The donor kidney was first transplanted into a 32-year-old patient with renal atrophy. More than 2 years later, he suffered from severe grand mal seizure with brain edema and the patient met the criteria for brain death.
