Study population: HIV-1 positive persons who are included in a cure intervention study

Brief summary: The aim of this study is the gain new insights into HIV latency before and after cure intervention studies through extensive blood and tissue sampling (lymph node and colon biopsies) from 30 individuals.


Eligibility criteria: Inclusion Criteria:

* Meets the inclusion criteria of the cure intervention study

Exclusion Criteria:

* Current history of opportunistic infection (AIDS defining events as defined in category C of the CDC clinical classification), consisting of chronic HIV-1 infection.
* Evidence of active HBV infection (Hepatitis B surface antigen positive or HBV viral load positive in the past and no evidence of subsequent seroconversion (=HBV antigen or viral load negative and positive HBV surface antibody)).
* Evidence of active HCV infection (HCV antibody positive result within 60 days prior to study entry with positive HCV viral load or, if the HCV antibody result is negative, a positive HCV RNA result within 60 days prior to study entry).
* Current or known history of cardiomyopathy or significant ischemic or cerebrovascular disease.
* Current history of cancer.
* History of HIV-related thrombocytopenia.
* Pregnancy or breastfeeding.
* Any condition, including preexisting psychiatric and psychological disorders, which will in the opinion of the investigator interfere with the trial conduct or safety of the participant.
* Abnormal results of standard of care laboratory tests:

  1. Confirmed haemoglobin \<11g/dl for women and \<12 g/dl for men
  2. Confirmed platelet count \<100 000/µl \*
  3. Confirmed neutrophil count \<1000/μl
  4. Confirmed AST and/or ALT \>10xULN
* Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
* Acute or serious illness, in the opinion of the site investigator, requiring systemic treatment and/or hospitalization within 60 days prior to entry.
* The following treatment will be prohibited three months before screening and during the study:

  1. immunosuppressive drugs (inclusive corticosteroids) except for drugs used for topical use.
  2. Immunomodulatory drugs including but not limited to Granulocyte-colony stimulating factors, Granulocyte-monocyte colony-stimulating factor, interleukin 2, 7 \& 15.
