Active clinical trials for "Cytomegalovirus Infections"

If the participant decides to take part in the study, the participant will need to do the following: Visit the study clinic up to 10 times and be available for a reasonable amount of follow up phone calls to see how the participant is doing. The participant will receive three doses of vaccine injected into the muscle of the upper arm. After each injection the participant will be asked to remain at the study site for at least 30 minutes after the participant receives the study vaccine. The results of all of the participants blood tests, just like all other laboratory test results, will be provided to the Investigators, Sponsor, and vaccine developer. Positive HIV and viral hepatitis test results will be reportable to local health authorities according to local laws. The participant will be asked to refrain from excessive physical activities and alcohol consumption within 2 days before each clinic visit to avoid possible confusing effects on laboratory tests.

An open-label randomized controlled trial to adapt the duration of antiviral prophylaxis in D+/R- patients and in R+ patients receiving ATG according to the result of the T-Track® CMV assay. Investigators will include kidney and liver transplant recipients. Patients will be randomized during the first month post transplant. In the interventional arm, while the patient is on antiviral prophylaxis, CMI will be monitored every 4 weeks from the 2nd month after transplant. Measurement of CMV CMI will be done in real time by using the T-Track® CMV assay. The continuation of antiviral prophylaxis will depend on the result of the assay: T-Track positive (patient at lower risk): discontinuation of the antiviral drug T-Track negative (patient at higher risk): continuation of the antiviral drug until the maximal duration of prophylaxis (3 to 6 months) The standard arm will receive a standard fixed duration of antiviral prophylaxis (3 months for R+ thymoglobulin treated-patients and 6 months for D+/R- patients). Measurement of CMV CMI by both T-Track® CMV and the Quantiferon-CMV® assays will be done at the same time points of the interventional arm, but the result will not be known by the investigators. After discontinuation of prophylaxis, patients in both arms will be followed for the development of CMV replication at each visit using the local PCR assay and antiviral therapy will be administered in case of CMV infection according to local guidelines. The co-primary endpoints will be the incidence of CMV disease or antiviral-treated CMV replication during the first 12 months post transplant AND the duration of antiviral prophylaxis.

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.

The purpose of this study is to estimate the incidence of Cytomegalovirus (CMV) secondary infections (re-infections/re-activations) and the incidence of CMV primary infections in adolescent females.

To evaluate, in a prospective multicenter study, ultrashort-term heat inactivation for the prevention of Cytomegalovirus (CMV) transmission in preterm infants (<32 weeks gestational age or <1500 g birth weight) under clinical conditions. Inactivation will be done only during the period of infectivity of breast milk, characterized by viral excretion strongly associated with subsequent infection, monitored by periodic virologic examinations of BM and urine of the infant. Thus the investigators hypothesis is that no CMV transmission through breast milk will occur using a gentle ultrashort heat inactivation procedure applied to infective breast milk. The protocol has been approved by the ethics committee of Tuebingen University Hospital.

The primary objective of this study is to evaluate the pharmacokinetics (PK) of letermovir (LET) in pediatric participants. Participants will be enrolled in the following 3 age groups: Age Group 1: From 12 to <18 years of age (adolescents); Age Group 2: From 2 to <12 years of age (children); and Age Group 3: From birth to <2 years of age (neonates, infants and toddlers). All participants will receive open label LET for 14 weeks (~100 days) post-transplant, with doses based on body weight and age.

The purpose of this study is to develop a brief screening and behavioral intervention for the prevention of congenital cytomegalovirus (CMV) that will both be acceptable to clinic staff and feasible to implement as part of routine clinical prenatal care, and to test whether behavioral intervention for susceptible pregnant women can lead to a behavioral change that is likely to lead to decreased primary CMV infection. The study research assistants will enroll pregnant women who are less than 20 weeks' gestation, either English or Spanish-speaking and that do not have a primary CMV infection (never been infected or previously infected). Enrollment will occur during the woman's prenatal visit.

The study will prospectively determine the clinical utility of CMV cell-mediated immunity using the Quantiferon test. The investigators will use the assay results to tailor the duration of CMV prophylaxis in solid organ transplant patients.

Congenital cytomegalovirus (cCMV) is the most common non-genetic cause of pediatric hearing loss and an important cause of neurodevelopmental delay. Symptomatic infants are readily identified and quickly referred for treatment, but the majority of infants (85-90%) with cCMV show no symptoms at birth and therefore do not receive timely treatment. Often, these otherwise asymptomatic infants with cCMV may have early congenital hearing loss and therefore fail the newborn hearing screen, but because they are not specifically identified as having cCMV there is a delay in seeking further audiology exam and treatment of the CMV infection. This study will investigate how testing newborns for congenital cytomegalovirus infection (cCMV) after a failed newborn hearing screens can improve early identification of cCMV infection and therefore reduce the delay in referral of the newborn to appropriate specialists for intervention.

The purpose of the study is to assess the incidence and severity of late Cytomegalovirus (CMV) disease, defined as CMV syndrome or tissue invasive disease occurring between 100 and 200 days and after 200 days post-transplant in patients treated with valganciclovir per package insert guidelines for prophylaxis against CMV infection for 200 days post-transplant versus valganciclovir per package insert guidelines for 100 days post-transplant with Cytogam 100 mg/kg administered at 90 days, 120 days, and 180 days post-transplant.
