Filter by:Liver is an organ that is well-known for its immune tolerant capacity. However, there were still controversial issues about the impact of immunologic challenge after liver transplantation on the graft function. Different results of graft function affected by immunologic factors such as pre-transplant panel reactive antibody (PRA) status, pre-transplant positive lymphocyte cross match (LCM), or post-transplant circulating donor specific antibody (DSA) has been reported according to individual institutes. There was no trial for presenting anti-donor lymphocyte antibody change after liver transplantation. The investigators designed this study to analyze the correlation between pre- and post-transplant immune status (PRA, LCM), and graft survival / rejection episode. Also, the investigators will find aspects of anti-donor lymphocyte antibody change after liver transplantation.
Acute cellular rejection is relatively common after liver transplantation, typically does not affect graft survival, and is not associated with the development of chronic rejection. Acute cellular rejection is diagnosed when liver enzymes and/or liver function tests are elevated when compared to baseline. The only means of differentiating acute rejection from other liver pathologies is with a liver biopsy. However, even with this invasive diagnostic procedure, it may be difficult to distinguish acute rejection from another disease process, such as injury caused by the hepatitis C virus (HCV) from the native liver. This study will evaluate whether certain patterns of biomarkers in the peripheral blood and/or liver tissue of a liver transplant recipient can be used to determine if the transplanted liver is being rejected by the recipient or sustaining HCV injury. Diagnostic biomarkers that are specific for acute rejection and informative of the severity of HCV recurrence could allow for modulation of immunosuppression therapy and treat the clinical condition without the need for invasive liver biopsies.
Patients with liver failure undergoing liver transplantation often have clinical or sub-clinical encephalopathy that may lead to increased intracranial pressure. The latter may lead to abnormal regulation of blood flow to the brain (cerebral autoregulation) complicating patient management during and after general anesthesia. The current methods for monitoring for elevated intracranial pressure are invasive and, thus, limited to severe encephalopathy. In this study the investigators will evaluate the potential utility of monitoring cerebral blood flow (CBF) autoregulation non-invasively using near infra-red spectroscopy in patients undergoing liver transplantation.
- Liver/renal transplantations are now tending to be the most important treatment for terminal liver and renal disease. Although transplantation can prevent recipients from suffering with critical and fatal symptoms, patients may experience the complication from surgery and immunosuppressive drugs. Furthermore, they might have many unmet needs in daily life, and so as their spouses. The purpose of this study is to explore the home-care needs among the post liver or renal transplant recipients and their spouses, and identify the significant factors for care needs. - A cross-sectional correlated design will be used and patients will be recruited by purposive sampling from an organ transplant outpatient department at a medical center in northern Taiwan. A set of structured questionnaires will be used to collect data. - The result of this study will be helpful for clinical nurses to understand liver or renal recipients' physical and mental distress, also identify the potential risk of home-care needs and the degree of satisfaction as well.
The vecuronium requirements may be reduced for recipients of living donor liver transplantation, as the vecuronium is eliminated principally by the liver. Furthermore, the requirements may be different according to the phase of surgery. The requirements may also be different according to the preoperative hepatic function as measured by MELD score during prehepatic phase, or graft to recipient body weight ratio (GRWR) during neohepatic phase. Therefore, the investigators are trying to investigate the difference of vecuronium requirements according to the phase of surgery or MELD score, GRWR.
The purpose of this study, a follow up to study FG506-CL-0403, is to see how safe and effective Modigraf® is (Part A) and to see how safe and effective it is to change your child's medication from Modigraf® to Prograf® (Part B).
The purpose of this study is to find out how much of Modigraf is absorbed and used in the body and how fast it leaves the body (Pharmacokinetics). The results will then help to decide how much Modigraf in future can be given safely to children and young people following transplantation.
The purpose of this study is to investigate and compare the pharmacokinetic parameters of tacrolimus from Advagraf and Prograf in de nove living donor liver transplant recipients.
As is well known, immunosuppressive treatment (IS) after liver transplantation has several and frequents adverse effects that limit the survival of the graft and recipients. Because of that, it is desirable that these recipients were able to receive a mild IS regime with a better safety profile. An attempt to get that aim has been evaluated in several trials in the past, and consist in to change the IS regime from an calcineurin inhibitors (CNI) based to another less intense and with less adverse effects based on mycophenolate mofetil (MMF), which is known to have a better safety profile. The success rate of this strategy(i.e. complete conversion in absence of rejection) has a wide range from 100% to 50% approximately. However it is accepted that this strategy is associated with the improvement of several adverse effects of CNIs such as renal failure and dyslipemia. This study's aim is to perform IS conversion from CNI to MMF monotherapy and look for transcriptional biomarkers employing a whole genome expression study performed with microarrays at baseline on liver tissue and/or PBMCs to try to find a differential gene expression able to correlate with a successful conversion and thus, to generate a set of transcriptional biomarkers potentially able to predict the result of the IS conversion on an independent cohort of liver recipients.
Saliva is used nowadays as a significant diagnostic tool due to the latest technological developments. The research compares two experimental groups; children after liver transplantation and a control group. Our objective is to identify from all the parameters that are evaluated, the ones that differ between the two groups. If such parameters will be found and differ statistically, it will be possible to create a non invasive medical examination protocol, which will probably be much more complaint, and being so would help locate individuals in risk groups with the tendency to develop an end-organ liver disease.
