Conditions
Summary
Aim of the study: To study and to describe factors which could influence the course of primary HIV infection (PHI) and factors that in turn could be influenced through PHI. In summary, this study will provide comprehensive knowledge on early HIV-infection with regard to epidemiology, impact of early-cART on the course of disease and forms the base for a variety of translational research projects addressing early key pathogenesis events between virus and host, relevant for the course of disease, for transmission, for development of vaccines and new treatment strategies.
Eligibility
Inclusion Criteria8
- A) acute HIV-1 infection, defined as:
- negative or evolving immunoblot in the presence of positive p24 Ag and/or detectable plasma HIV-1 RNA and/or
- documented HIV seroconversion within 90 dayswith or with-out symptoms and/or clinical signs of PHI (e.g. acute retro-viral syndrome).
- B) recent HIV-1 infection, defined as:
- documented seroconversion of more than 90 days but within 180 days and/or
- evolving immunoblot after unambiguous transmission risk (e.g. iv drug use, sexual contact) within 180 days and/or
- documented HIV infection and unambiguous transmission risk (iv drug use, sexual contact) within 180 days and/or
- documented HIV infection and possible transmission risk (iv drug use, sexual contact) within the last 180 days after infection AND \< 0.5% fraction of ambiguous nucleotides
Exclusion Criteria1
- • Documented HIV infection, however, established diagnosis more than 180 days after presumed date of infection.
