Primary objectivesLongitudinal quantification of the total latent HIV reservoir with determination of the size of the replication competent HIV reservoir and investigate potential biomarkers of the HIV reservoir size and nature.Cross compare the…
The primary objective of this Registry is:• To evaluate HCV viral sequences and the persistence or evolution of treatment emergent viral mutations in subjects who fail to achieve an SVR after treatment with a Gilead oral antiviral containing regimen…
Study of the phenotype and function of NK cells obtained from peripheral blood and liver of patients who are successfully being treated for at least 3-4 years for their chronic HBV infection with tenofovir in a flow-up study (METC nr. 2008-271).
Main: To assess the effect of an early extra measles immunization between 6and 12 months of age on the development of humoral and cell-mediatedimmunity against measles following routine MMR immunization at 14months of age.Secundary:Determine effect…
Primary Objective: to investigate the role of the gut microbiota in RVV immune response Secondary Objectives: To investigate the role of the gut microbiota in tetanus and pneumococcal vaccine immune responses
1. Determine whether different classes of epigenetic modifiers affect HIV-1-specific T cell immunity.a. Investigate whether HIV-specific T cell exhaustion can be reversed by inhibitors of different classes of epigenetic modifiers.b. Examine whether…
PrimaryTo determine whether the palatability of a newly developed formulation of valacyclovir is non-inferior to administration of crushed and suspended tablets in children, is the primary objective of the second phase of the trial.The primary…
The primary objective of this Registry is:*To evaluate the long term effects of Hepatitis B Virus (HBV) treatment of the parental study on the HBV serologic changes through Week 144 The secondary objective of this Registry is :*To evaluate the long…
This study aims to identify global and local determinants of HPV vaccine acceptability, HPV vaccine uptake and compliance as well as identify logistics and programmatic issues in each country to offer the HPV vaccine, as a potential cervical cancer…
The objectives of this study are: 1) To assess the user friendliness of the DBS self-sampling technique.2) To assess the quality of ssDBS.3) To estimate the agreement between viral loads in ssDBS and laboratory spotted DBS (labDBS).
To identify and quantify the HIV reservoir in T-cell subsets of patients who have been on ART for almost 20 years.
Main objective: To quantify mumps transmission parameters in exposed individuals, comparing symptomatic and asymptomatic cases, to understand and model ongoing transmission; Secondary: to assess cellular immuunresponses in mumps exposed infected and…
Recent studies demonstrate long-term durability of virologic response with pegylated alpha-interferon-based therapies. Comparable information is not yet available for Lambda or for regimens combining lambda interferons, RBV, and DAAs. In this…

To evaluate in detail the functionality of immune cells in blood in chronic HCV patients before, during and after treatment with ASV and DCV, in an IFN-free regimen.
To externally validate the accuracy of a host-response based diagnostics for differentiating between bacterial and viral etiology in pediatric patients aged 2 to 60 months with LRTI or FWS.
This study aims to investigate the effect of switching from Atripla® to Eviplera® on neurocognitive performances (neurocognitive testing) and imaging (functional MRI scanning) in virologically suppressed HIV-infected patients and stable on atripla.
