Filter by:This retrospective review will evaluate the efficacy of Valcyte (valganciclovir) in preventing Cytomegalovirus (CMV) disease in D+/R- liver transplant recipients. Data from eligible patients will be collected for the 6 months following transplantation.
CMV is one of the most important opportunistic infection in transplant recipients. In South Korea, more than 95% of adults reveal sero-positivity for CMV IgG. Until now, sero-positivity for CMV IgG before solid organ transplantation is a laboratory test of choice to stratify the risk of CMV reactivation after solid organ transplantation. Theoretically, CMV-specific cell-mediate immune response before solid organ transplantation will further categorize the patients into high or low risk of CMV development after solid organ transplantation. The investigators thus evaluate the usefulness of CMV-specific ELISPOT assay in kidney transplant candidates to predict the development of CMV infection after kidney transplantation.
To assess the feasibility of donor-derived interferon (IFN)-γ positive select-ed virus-specific T-cells using the cytokine capture system® (CCS) and the safety of subsequent infusion in recipients of hematopoietic stem cell transplantation (HSCT) with treatment refractory post-transplant viral infections. The CCS has already been successfully used in clinical studies in Germany and United Kingdom (UK).
The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.
This study will evaluate the safety, tolerability, and immunogenicity of various doses, formulations, and routes of administration of Human Cytomegalovirus (HCMV) vaccine V160 administered in a 3-dose regimen in healthy adults. The initial treatment arm of HCMV seropositive participants will receive V160 Low Dose without adjuvant by intramuscular injection. Escalation of the V160 dose, inclusion of adjuvant, administration by intradermal injection, and vaccination of HCMV seronegative participants will be performed only after review of safety data of previous treatment arms. The purpose of the study is to identify vaccine formulations associated with optimal safety profile and HCMV-specific immune response for evaluation in subsequent clinical studies of V160.
Our study will compare all kidney transplant recipients receiving valganciclovir vs. valacyclovir for one year following kidney transplant and compare: 1. the incidence, magnitude and duration of CMV and EBV viremia in the first year after transplant. 2. the side effects of the anti-viral drugs requiring dose reduction or cessation In addition, we will test renal tissue obtained from any biopsies post-transplant (surveillance or clinically indicated biopsies) by both polymerase chain reaction (PCR) and fluorescence in situ hybridization to assess for latent CMV and/or EBV.
Subjects have a type of blood cell cancer, other blood disease or a genetic disease for which they received a stem cell transplant. After transplant while the immune system grows back the subjects have an infection with one or more of three viruses - Epstein Barr virus (EBV), cytomegalovirus (CMV) or adenovirus - that has persisted or come back despite standard therapy. Adenovirus is a virus that causes symptoms of a common cold normally but can cause serious life-threatening infections in patients who have weak immune systems. It usually affects the lungs and can cause a very serious pneumonia, but it can also affect the gut, the liver, the pancreas and the eyes. CMV is a virus that can also cause serious infections in patients with suppressed immune systems. It usually affects the lungs and can cause a very serious pneumonia, but it can also affect the intestinal tract, the liver and the eyes. Approximately 2/3 of normal people harbor this virus in their body. In healthy people CMV rarely causes any problems because the immune system can keep it under control. If the subject and/or the subject's donor are positive for CMV, s/he is at risk of developing CMV disease while his/her immune system is weak post transplant. EBV is the virus that causes glandular fever or kissing disease. It is also normally controlled by a healthy immune system, but when the immune system is weak, it can cause fevers, enlarged lymph nodes and sometimes develop into a type of cancer called lymphoma. This treatment with specially trained T cells (called CTLs) has had activity against these viruses when the cells are made from the transplant donor. However, as it takes 2-3 months to make the cells, that approach is not practical when the subject already has an infection. We want to find out if we can use CTLs which have already been made from another donor that match the subject and his/her donor as closely as possible and if the CTLs will last in the body and have activity against these viruses. In a recent study these cells were given to 50 patients with viral infections post transplant and over 70% had a complete or partial response. The purpose of this study is to make CTL lines leftover from that previous study available to patients with viral infections that have not responded to standard treatments. These virus-specific CTLs are an investigational product not approved by the FDA.
This phase I trial studies the side effects and the best dose of vaccine therapy in healthy volunteers with or without previous exposure to cytomegalovirus. Vaccines made from a gene-modified virus may help the body build an immune response and may help prevent cytomegalovirus infection.
CMV infection is common in transplant patients and can cause graft loss. CMV is a major factor in increasing morbidity, and post-transplant costs. The CMV infection is associated with many deleterious indirect effects including rejection, interstitial fibrosis and tubular atrophy, mortality. In addition to the potential for undesirable clinical outcomes associated with CMV, there is also a negative economic aspect. Patients who developed CMV events have been found to use significantly more inpatient and outpatient resources than patients without CMV disease. Universal prophylaxis is associated with high treatment cost and the potential for drug-related toxicity. It can be speculated that use of EVR may offer additional economic benefits in terms of decreased utilization associated with prevention of CMV disease, and reduce use of costly prophylaxis. Any efforts to reduce costs in renal transplants are very important and may have a great impact in total cost of a renal program. And the other hand, the clinical data suggest that EVR is associated with a decrease in CMV incidence compared to mycophenolic acid (MPA). CMV replication is dependent upon 1 ou 2 mTor pathways and in vitro studies support an association between mTor inhibitors and decreased CMV infection and disease. In cardiac transplantation, the use of EVR was associated with a lower incidence of CMV events. Some clinical trials data have also shown that use of EVR was associated with a lower incidence of CMV infection compared to MPA following renal transplantation. Brennan et al compared the incidence of CMV in three clinical trials using EVR versus MPA in De Novo renal transplants. They pooled for analysis the studies B201, B251 and A2309, all double-blind, randomized, parallel-groups that compared the incidence of freedom form and incidence of CMV between EVR groups and MPA groups. The results of this pooled analysis of over 2000 patients de novo renal transplant demonstrated that EVR was associated with a decrease in and delay in the time of onset of CMV events compared to MPA. Our hypothesis is that basiliximab in combination with low dose tacrolimus, everolimus and prednisone may result in comparable efficacy (BCAR) observed in patients receiving tacrolimus/mycophenolate/prednisone but with a better safety profile (CMV infection) and cost-effectiveness.
The main objective of this study is to validate , in the neonatal period, a prognostic score for the development of neurosensorineural sequelae at 1 year and at 2 years in neonates infected in utero by cytomegalovirus. This score will be based on clinical, imaging and biological criteria . The second objective of the study is to estimate the prevalence of this infection in France and to describe its epidemiology through the screening of 12,000 consecutive neonates.
