Filter by:This study is a single-center, prospective, non-interventional cohort study based on the real world data.In this study, 30 patients with a history of PD-1/PD-L1 monotherapy prior to liver transplantation and 30 patients without a history of PD-1/PD-L1 monotherapy prior to liver transplantation were recruited from the group of patients with hepatocellular carcinoma who had undergone allogeneic liver transplantation.Collected patient data included demographics, oncology and immunotherapy history, evaluated index before liver transplantation, laboratory, pathological and imaging results at specific time points after transplantation (1 week, 2 weeks, 3 weeks, 4 weeks, 12 weeks, 16 weeks, 24 weeks), as well as the occurrence of acute rejection (AR) , grading of severity, and anti-rejection treatment plan at the same time. Endpoints included relapse-free survival and overall survival (OS). These data aims to assess: 1) the incidence of acute rejection after liver transplantation in patients with hepatocellular carcinoma; 2) the time of acute rejection, Banff classification, and acute rejection-related mortality after liver transplantation in patients with hepatocellular carcinoma; 3) the cellular immune function after liver transplantation;; 4) the dose and drug concentration of tacrolimus after liver transplantation in patients with hepatocellular carcinoma; and 5) the overall survival (OS) and relapse-free survival(RFS) after liver transplantation in patients with hepatocellular carcinoma.
This study is being done to test blood, urine and tissue samples to see if this can help decide if CKD (Chronic Kidney Disease), AR (Acute Rejection) and HCV (Hepatitis C Virus) can be identified in its early stages. CKD damage to the kidneys, AR and HCV all lower the body's ability to function properly. Early detection of these conditions could assist with successful treatment and possibly lead to less repeat organ transplants.
Acute kidney allograft rejection is the major cause for a loss of graft function and has a negative impact on long-term graft survival. Anti-rejection therapy traditionally focuses on T cell-mediated mechanisms of renal allograft rejection. However, available agents that affect T-cell pathways have only little impact on long-term graft survival. There is increasing evidence that B-cells play an important role in acute transplant rejections. CD20+ B cell infiltrates in acute T-cell mediated rejections are frequent and correlate with a worse response to conventional anti-rejection treatment and an increased risk of graft loss. In one pilot study, supported by several case reports, a beneficial effect of Rituximab for the treatment of acute rejection episodes with intrarenal B-cell infiltrates was shown. However, despite the promise of these observations solid evidence is required before incorporating this treatment option into a general treatment recommendation. In a multicenter randomized placebo controlled double blind phase III trial the investigators want to demonstrate that Rituximab in addition to standard treatment with steroid-boli is superior to the standard treatment alone regarding long-term kidney function. If the proposed study proves that Rituximab treatment of acute rejections is beneficial for the long-term allograft function, the conventional rejection therapy needs to be revised to this novel concept of B- cell targeting
The hypothesis of this study is that lymphocyte depletion by Campath-1H and rituximab will obviate the need for long-term calcineurin inhibitors in renal transplantation. Most successful strategies to date have relied on the use of either tacrolimus or cyclosporine for an indefinite period of time. However, the advantage of a long term, calcineurin inhibitor free regimen may include improved renal allograft function, a lower incidence of hypertension, diabetes, and less drug related side effects. This is a non-randomized open-label pilot trial in 30 adult renal transplant patients. Subjects will receive 2 doses of Campath-1H (30mg given on Day 0 and Day 1) and a single dose of Rituximab (375mg/m2) on Day 0, given intra-operative. Subjects will take maintenance doses of prednisone and enteric coated mycophenolate sodium (Myfortic™). Subject will also be given cyclosporine (Neoral®) therapy for approximately 2 weeks (10-20 days).
