Laboratories:

Laboratory testing will be done at Dept. of Retrovirology, AFRIMS, The Thai Red Cross AIDS Research Centre (TRCARC), Bangkok, Thailand; the Division of Retrovirology, WRAIR; and WRAIR’s collaborating laboratories [the National Cancer Institute (Frederick, Maryland, USA); the National Institute of Allergy and Infectious Diseases (Bethesda, Maryland, USA) and the Vaccine and Gene Therapy Institute (Port Saint Lucie, Florida, USA)].


Source of Funding: MIDRP Research Area H Task Area 1C
Sponsor:

  1. Division of Retrovirology, Walter Reed Army Institute of Research, Rockville, MD for study conduct (MIDRP 1C0025-08, expiry date of September 2011). Funding will transition to HIV Vaccines Advanced Development 811/812 until study completion.


Study Duration: 6 years including at least 6 months of preparation, 48 months (4 years) for recruitment. Each subject will have different lengths of follow up (maximum 48 months and minimum is around 24 months).
Anticipated Start Date: April 2009
Anticipated Completion Date (Month and Year): April 2015
Required Number and Type of Study Subjects: We expect to enroll up to 75 subjects aged 18 years and up with acute HIV infection over 4 years.

1. STUDY SUMMARY

Objectives

Primary:

To describe clinical, immunological, and virological characteristics of persons with acute HIV infection


Secondary:

  1. To describe demographics and behavioral risk factors for those identified with acute HIV infection




  1. To describe neurocognitive function and neuroimaging findings in acute HIV infection as well as describe immune response, HIV-1 genotypes and sequences in the cerebrospinal fluid.




  1. To describe the number and characteristics of sexual contacts




  1. To describe the willingness of acute HIV-infected subjects to allow the tracking of their sexual contacts for voluntary HIV counseling and testing (VCT)




  1. To describe immune response, HIV-1 genotypes and sequences in the genital compartment




  1. To describe T cell depletion in the gut mucosa in acute HIV infection and describe the changes in gut T cells during follow up




  1. To archive samples for future investigations including determination of viral evolution, and cell-mediated and humoral immune responses in peripheral blood and mucosal compartments


Subject population: Male and female clients age 18 years old and up who are seeking VCT at the TRCARC and have a protocol-defined laboratory finding of acute HIV infection (Either negative 4th generation enzyme immunoassay (EIA) and positive HIV nucleic acid (NAT) OR positive 4th generation EIA and negative EIA by a less sensitive method
Number of subjects: Approximately 40,000 subjects will be screened to enroll approximately 75 acute HIV infection subjects over 4 years.
Treatments of subjects who are identified to have acute HIV-infection: The decision to initiate highly active antiretroviral therapy (HAART) will be up to the subject and his/her physician. Subjects will be referred to the HIV clinic at the TRCARC or other clinics of their choice for routine HIV care. Subjects may be enrolled in other treatment protocols. No modification to follow-up or protocol procedures will be made if subjects choose to receive antiretroviral treatment.

Study design and methodology: Subjects will be recruited at the TRCARC (Procedures shown in Table 1). Subjects seeking VCT will be asked to provide contact information (expect 500-800 subjects per month). Blood samples, either plasma or whole blood collected on filter paper (dried blood spots or DBS) will be screened for acute HIV infection by pooled or individual NAT if non-reactive after screening by an EIA capable of detecting both HIV antibody and antigen (4th generation or sensitive EIA). Additionally, 4th generation reactive samples will be screened with a non-IgM sensitive EIA capable of detecting HIV antibody only (less sensitive EIA) within 1-2 days of sample collection. Those who are found to have acute HIV infection will be asked to enroll in the cohort study (Table 2). These acute HIV-infected participants will be followed prospectively at week 0, day 2, 3, 5, 7, 10 then weeks 2, 4, 8, 12, 16, 20, 24, then every 12 weeks until the end of the study (maximum of 192 weeks of follow up). Subjects will receive blood testing for CD4, HIV RNA, ALT, creatinine and lipids, and urinalysis according to Table 2. Subjects will be asked to complete a questionnaire on HIV risk behavior. Neuropsychological assessment, comprehensive neurological examination, psychiatric questionnaires, and assessment of function will be performed. Archiving of plasma and PBMC for future immunologic and virologic testing will be performed by either leukopheresis or phlebotomy for weeks 0, 2, 4, 8, 12, 24, 48 and 96, and by phlebotomy for the remaining study visits). Optional study procedures include 1) collection of genital secretions 2) collection of cerebrospinal fluid 3) brain MRI/MRS without gadolinium 4) sampling of gut-associated lymphoid tissue by colon biopsy 5) genetic testing 6) tracking of and offering VCT to sexual contacts of acute HIV-infected subjects. Subjects are encouraged to be hospitalized for the first 3-7 days for post-procedural observation and for ease of follow up. The total maximum volume of blood is 1,267 ml over 4 years.
SCHEDULE OF EVENTS

Table 1: Recruitment procedures

Steps

Procedures

1

Subjects seeking VCT service are given an information sheet explaining the acute HIV infection cohort study . Subjects are asked for contact information, and permission to contact them should they be found to have acute HIV infection

2

All VCT samples (without personal identifiers) are tested for acute HIV infection within 1-2 days of sample collection

3

Laboratory staff notify the study physician and nurse immediately about samples confirmed to have acute HIV infection

4

The study physician and nurse contact subjects immediately. Subjects are counseled on the results of testing and asked to return to clinic for further counseling and for enrollment in the acute HIV cohort study

5

The study physician and nurse consent subjects for the acute HIV cohort study. The Consent forms are included in main consent and optional procedures

Subjects have no obligation to follow any of the study procedures specified above and are able to continue receiving services at the TRCARC without any prejudice towards them.
