Filter by:This is an open-label, controlled study, conducted at US sites to evaluate the anti-inflammatory effectiveness of the study drug letermovir in adults with HIV and asymptomatic cytomegalovirus (CMV) who are on antiretroviral therapy (ART)-mediated suppression. Participants will be randomly assigned to receive either letermovir once daily or no anti-CMV treatment, for 48 weeks.
The cCHIPS study is a feasibility study for larger scale multi-centre studies and is designed as a single-centre observational cohort, longitudinal, natural history study. The overarching aim of this study is to evaluate the feasibility of performing larger scale, multi-centre studies to evaluate the relationship between CMV shedding in pregnancy with congenital CMV (cCMV). There is no randomisation involved in this study and all participants will perform the same study procedures and receive treatment as usual. The primary (main) objective is to evaluate the prevalence (percentage of occurrence) of CMV shedding in saliva, urine and vaginal secretions of CMV seropositive women throughout pregnancy. The secondary objectives are to evaluate the quantity of CMV shedding in saliva, urine and vaginal secretions of CMV seropositive women throughout pregnancy, to compare the prevalence and quantity of CMV shedding in CMV seropositive women between different sources of shedding (saliva, urine or vaginal secretions) and different gestational stages, to identify risk factors for CMV shedding in CMV seropositive pregnant women, to evaluate the acceptability of the study procedures to the participating pregnant women, to evaluate the proportion of women approached who are recruited into the study and who are completing the study, and to evaluate the relationship between CMV specific cell mediated immunity (a type of immune protection following exposure to CMV) and CMV shedding in CMV seropositive pregnant women. The tertiary objective is to compare the evaluation of CMV specific T cell immune responses (a type of CMV specific cell mediated immunity) between the two commercially available CMV-specific T cell immune response assays which are QuantiFERON-CMV and CMV-ELISPOT assays. This study will aim to recruit 200 pregnant women. This study will be undertaken in parallel with a separate study called RACE-FIT (REC reference number 18/SC/0360, IRAS ID 239977), which will have ethical approval to screen pregnant women with children less than 4 years of age booked for their antenatal care at St George's Hospital, London, identified during the antenatal combined screening bloods appointment or the antenatal booking appointment, for their CMV serology status on a sample of blood collected as part of the screening process. As part of the ethical approval sought for the RACE-FIT study and the cCHIPS study, the pregnant women screened and found to be CMV seronegative will be eligible for recruitment into the RACE-FIT study and those screened and found to be CMV seropositive will be eligible and approached for recruitment into the cCHIPS study. The cCHIPS study aim to recruit over a 6 month period. The study involves four visits (Visit 1, Visit 2, Visit 3, Visit 4) for each participant. The total study period for each participant will be between 6 to 8 months.
To evaluate the illumigene CMV assay, using the illumipro-10 with neonates (up to 21 days of age) saliva swabs
Fecal microbiota transplantation (FMT) is recommended in the treatment of recurrent Clostridium difficile infection (CDI). The principle is to administer a fecal suspension of a healthy subject (donor) in the digestive tract of a patient with an CDI (receiver). Donors are being clinical and laboratory screening to reduce the likelihood of pathogens transmission (infectious and other). Cytomegalovirus (CMV) is part of the examinations requested by the Agence national de sécurité du médicament et des produits de santé in the context of clinical research. A sero-matching between donor and recipient CMV is requested. This recommendation eliminates many potential donors to a recipient. To date, the frequency detection level of CMV in stool in healthy volunteers with documented positive CMV serology is not known. In addition, CMV transmission risk via the stool is not established. This study aims to determine the detection frequency of CMV in healthy volunteers stool samples selected as potential donors for a FMT and having a positive CMV serology documented
In this study, investigators are trying to see if infusion of "m-CTLs" will prevent or treat cytomegalovirus (CMV), Epstein Barr Virus (EBV) and adenovirus (AdV) reactivation or infection after cord blood transplant. Patients with blood cell cancer, other blood disease or a genetic disease may receive a cord blood transplant (UCBT) from an unrelated donor. After receiving a cord blood transplant, they are at risk of infections until a new immune system to fight infections grows from the cord blood cells. In this study, investigators are trying to give special cells from the cord blood called T cells. These cells will try to fight viruses that can cause infection. Investigators will test to see if blood cells from donor that have been grown in a special way, can prevent patients from getting an infection. EBV, AdV and CMV are viruses that can cause serious life-threatening infections in patients who have weak immune systems after transplant. T lymphocytes can kill viral cells but normally there are not enough of them to kill all the virus infected cells after transplant. Some researcher have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person during a viral infection after a bone marrow transplant. Some of these studies have shown a positive therapeutic effect in patients receiving the CTLs (specially trained T cells) after a viral infection in the post-transplant period. In this study we are trying to prevent or treat viral infections by given the CTLs soon after getting the umbilical cord blood transplant. With this study, investigators want to see if they can use a kind of white blood cell called T cells to prevent or treat AdV, EBV and CMV infection. Investigators will grow these T cells from the cord blood before transplant. These cells have been trained to attack adenovirus/EBV/CMV- infected cells and are called multivirus-specific cytotoxic (killer) T-cells or "m-CTL." Investigators would plan to give patients one dose of m-CTL any time from 30 to 364 days after your transplant. They have used T cells made in this way from the blood of donors to prevent infections in patients who are getting a bone marrow or blood stem cell transplant but this will be the first time investigators make them from cord blood.
This randomized, double-blind, placebo-controlled, parallel group, multicenter study compared the effectiveness of oral brincidofovir (BCV) to placebo for the prevention of cytomegalovirus (CMV) infection in stem cell transplant patients who were CMV seropositive but negative for CMV viremia before starting treatment with BCV.
Cytomegalovirus (CMV) is the largest member of the virus family Herpesviridae that infects almost all humans at some point in their lives (Ross, 2004). Congenital CMV infection is most likely to occur when the mother experiences a primary infection during pregnancy, and it is much less common in cases of reactivation of the disease or infection by a different CMV strain (Boppana 1999, Endres 2001). The prevalence of congenital CMV infection varies between 0.15-2.2% (Ross 2004, Ross 2006, Malm 2007). While most infants born with congenital CMV infection are asymptomatic, 10 to 15% show clinical findings at birth (Ross 2004). It is generally agreed that congenital CMV infection, whether it is symptomatic or not, is a major risk factor for perceptual deficits. However, its influence on children's future neuropsychological functioning is less well established. Symptomatic congenital CMV infection is a major risk factor for poor developmental outcome (Williamson 1982, Kylat 2006, Dollard 2007), but the available data regarding neuropsychological outcome for asymptomatic children is extremely diverse (Conboy 1986, Ivarson 1997, Kashdan 1998, Temple 2000, Zhang 2007). We evaluated the neuropsychological outcome of children with congenital cytomegalovirus (CMV) infection and normal consecutive fetal neurosonographic examinations and determined whether Magnetic Resonance Imaging (MRI) provided additional information in these cases.
