Outcome Measures
Primary Outcomes (1)
T cell number and effector functions in Cytolin-treated blood harvested from HIV infected individuals.
Entry, 3 months, 6 months
Secondary Outcomes (1)
In-vitro suppression of viral replication following Cytolin treatment of blood harvested from HIV infected individuals.
Entry, 3 months, 6 months
Study Arms (2)
Early HIV infection
HIV infected adults with early evidence of suppressed cell-mediated immunity but whose disease has not progressed far enough to indicate antiretroviral therapy.
Control
Healthy adults without HIV infection.
Eligibility Criteria
Adult human subjects willing and able to have blood drawn at Massachusetts General Hospital in Boston, MA at baseline, three months and six months. All healthy volunteers have been enrolled and enrollment is now open only to subjects with earlyh HIV infection.
You may qualify if:
- HIV seropositive
- viral load \< 100,000 copies/ml
- CD4+ \> 350 cells/ul
- Ability and willingness to give written informed consent.
- Control Group
- HIV seronegative subjects identified as HIV uninfected by a nonreactive HIV 1/2 ELISA.
- Ability and willingness to give written informed consent.
You may not qualify if:
- Presentation with an opportunistic infection or AIDS-defining illness.
- Receipt of investigational research agent within 30 days prior to study entry.
- Prior receipt of experimental HIV vaccine, sham vector or adjuvant.
- Receipt of immunosuppressive medications or immune modulators within the past six months. Individuals taking corticosteroid nasal spray for allergic rhinitis, topical steroid or over the counter medications for acute, uncomplicated dermatitis for a period no longer than 14 days will not be excluded.
- Active drug or alcohol use, dependence or psychiatric illness that in the opinion of the study investigator would interfere with adherence to study protocol.
- Serious illness requiring hospitalization.
