|Brief Title ICMJE||Immune Responses to HIV in Blood Cells in HIV-Infected and HIV-Uninfected Volunteers|
|Official Title ICMJE||Studies of Specific Immune Responses in HIV-Infected and HIV-Uninfected Volunteers|
This study will explore the responses of the immune system to infection with HIV and other pathogens and the changes in these responses over time.
Healthy normal volunteers and HIV-infected patients 18 years of age or older may be eligible for this study.
Prior to enrollment and yearly thereafter, vital signs, height and weight will be recorded. A medical history will be obtained if relevant to the laboratory research for which the sample will be used. A more extensive history and physical exam is not required but may be performed if deemed necessary by the VRC clinician. A complete blood count will be performed on the day of enrollment and yearly thereafter. Samples will be collected in the following manner:
Blood will be drawn from a needle in an arm vein one or more times during the course of the study. From 20 to 150 cc (4 to 30 teaspoonfuls) of blood will be collected at a time. No more than 450 cc (less than 1 pint) of blood will be drawn during any 6-week period.
Urine and saliva samples will be collected by the volunteer in private.
Swab samples will be collected by a nurse or doctor, using a cotton swab to brush inside the mouth.
Samples may be used for the following tests:
Some samples collected in this study may be stored for future research.They will be labeled without identifying information.
Those with interesting or strongly positive immune responses may be asked to return to the VRC Clinic to provide samples of urine or oral secretions.
The Vaccine Research Center (VRC) is studying specific immune responses to HIV infection and other pathogens in order to characterize protective responses that can prevent new infection in uninfected individuals, as well as define those responses that lead to successful control of viral replication in persons already infected with the pathogen. We wish to define the specific human immune responses to HIV infection, other pathogens and vaccines using human peripheral blood mononuclear cells, plasma, serum, urine, or oral secretions as a model.
