Eligibility
Inclusion criteria
Inclusion criteria: In order to be eligible to participate in this study, a subject must meet the following criteria: -Written informed consent to store samples and perform genetic testing. -Separate written informed consent for invasive sampling procedures: leukapheresis, sigmoidoscopy with biopsies, lymph node biopsy or excision biopsy and lumbar puncture, to store samples and perform genetic testing. - Age >= 18 years - An acute HIV-1 infection, defined according to the modified Fiebig stages I-IV, as described in the previous paragraph (HIV-1 RNA positive and 4th generation ELISA negative or HIV-1 RNA positive and 4th generation HIV ELISA positive with indeterminate Western Blot). Patients in Fiebig stage V and VI will only be included if they have a documented negative HIV test 6 months prior to the (first) positive test. -Female subjects should be willing to use adequate contraception. Chronic control group: -Written informed consent to store samples and perform genetic testing -Separate written informed consent for sampling procedure: leukapheresis (or large blood draw), and/or lymph node excision biopsy, with storage of samples -Age >= 18 years -ART initiated in the chronic infection phase and chronic HIV-infection as confirmed by Western Blot (p31 positive) -Three to 5 years on ART with undetectable viral load and no more than two consecutive blips of >100 HIV RNA copies per mL of plasma in the year before enrollment Elite control group: -Written informed consent to store samples and perform genetic testing -Separate written informed consent for sampling procedure: leukapheresis (or large blood draw), and/or lymph node excision biopsy, with storage of samples -Age >= 18 years -Natural control of HIV infection, defined as having 3 undetectable HIV-1 RNA measurements >12 months upon diagnosis or 90% of HIV-1 RNA measurements undetectable >10 years.
Exclusion criteria
Exclusion criteria: -Contraindication for proposed cART regimen (e.g. impaired renal function) for participants enrolled with an acute HIV infection -Mental disorder that in the view of the investigator would interfere with adherence to the treatment or the study procedures, or the decision to participate in the study. -Immunosuppressive medication or other diseases associated with immunodeficiency.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
