Filter by:The purpose of this study is to study the prevalence of EBV, HCMV, HHV-6 in saliva and on the toothbrush patient with periodontitis.
The purpose of this research study is to test the safety and tolerability of four new investigational Cytomegalovirus (CMV) vaccines (Towne-Toledo 1, 2, 3, 4) in healthy male volunteers who are CMV negative. CMV is a common virus, infecting 50-80% of adults in the United States by the age of twenty-one. CMV does not usually cause illness in adults or children. However, CMV can be a cause of deafness and mental retardation in a child if a mother is infected during pregnancy. It also can be a serious illness in patients with impaired immunity (decreased ability to fight infection).
This study will look at the feasibility and acceptability of testing newborn babies who are referred after their newborn hearing screen for an infection called congenital Cytomegalovirus (cCMV). Around 1 in every 100 to 200 babies is born with this virus, and although most remain well it causes 1 in 5 cases of childhood deafness. Knowing that a baby is infected shortly after birth could have significant benefit since a treatment is now available, but screening programs need to be feasible and acceptable. This study aims to evaluate targeted screening for cCMV by taking samples (saliva and urine) from babies who do not pass their newborn hearing screening. The investigators want to see if we can find a quick, reliable and parentally acceptable way to screen babies who fail their hearing test for this virus.
The purpose of this study is to determine the seroprevalence of Hepatitis A Virus (HAV), Varicella-Zoster virus (VZV), Cytomegalovirus (CMV), Herpes Simplex (HSV) and Bordetella pertussis (BP)infections in Mexico.
The investigators aim is to determine the incidence of cytomegalovirus resistance to antivirals in a cohort study. The patients are included at their first CMV active infection and are followed during two years thereafter. When criteria for suspected resistance are meet, blood and urine samples are collected for virus isolation and further resistance phenotype, and for resistance genotype determination. Results are compared with baseline samples. Clinical information such as treatment, immunosuppressive regimen and clinical evolution will be collected. Through this study, the investigators aim to organize a national network for the detection and identification of CMV resistant strains that will be useful when new therapeutics will be available.
Direct DNA amplification, viral isolation and specific antibody measurement in saliva 1. From children in day care centers (samples collection will take place during a single week) 2. From children coming at the emergency department of our hospital during a three months period. Sample collection will be done by the pediatrician the nurse, or one of the authorized investigators of the study.
Cytomegalovirus infection threatens preterm infant. We investigated, whether thawed breast milk is a mode of transmission
The purpose of this study is to evaluate the effect of burn injury on the human immune system with a focus on cytomegalovirus (CMV) reactivation and the immunologic correlates of latent viral reactivation. Subjects will be patients admitted to the North Carolina Jaycee Burn Center with burn injury. Blood samples will be collected over time and will be evaluated for CMV reactivation and immune cell phenotype.
Various diagnostic methods are available for CMV infection. But none of them could be a standard and highly valuable. Our first goal is to setup a series of molecular diagnostic tools for HIV-1 infected person. By using these tools, physicians can easily select cases with CMV disease or immune restoration inflammatory syndrome (IRIS) to enroll this study. Furthermore, we will seek for a predict marker for CMV reactivation, CMV disease and IRIS. Finally, our research will focus on the mechanism of the IE gene alternative splicing between lytic and latent stage.
Cytomegalovirus (CMV) infects most of the world population. This study is to understand if chemotherapy will increase the chance of reactivating CMV. The results may help us in determining when treatment is needed and perhaps Why is it needed.
