Sequential Analysis Before and After Treatment Initiation to Unravel the Role of Naturally Occurring Extracellular Vesicles in HIV Infection

Exclusion Criteria34

• Recent HIV-infection, early diagnosis
• Previous or 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 or known history of cancer
• Pregnancy or breastfeeding
• Any conditions, including preexisting psychiatric and psychological disorders, which will in the opinion of the investigator interfere with the trial conduct or safety of the participant. An initial psychiatric assessment will be made by the treating physician. Since making a correct psychological assessment at the time of diagnosis can be difficult, a visit with a psychologist is planned for patients included in the study, for a second evaluation. This will be planned within the first month after diagnosis. In consultation with the psychologist, further sampling will be planned or the patient will be excluded from further sampling.
• Previous participation in a trial evaluating an immune modulating agent
• Abnormal laboratory tests results at screening:
• Confirmed hemoglobin \<11g/dl for women and \<12 g/dl for men
• Confirmed platelet count \< 100 000/µl
• Confirmed neutrophil count \<1000/μl
• Confirmed AST and/or ALT \> 10x ULN
• 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
• Known inflammatory bowel disease (Crohn's disease or ulcerative colitis)
• B. Healthy Volunteers
• HIV-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 or known history of cancer
• Pregnancy or breastfeeding
