Study of IRIS for Infants and Children Initiating HAART at Int'l Sites (P1073-IRIS)

This is a prospective, clinical observational and pathogenesis study of HIV-infected infants and children stratified into 2 age groups: ≥ 4 weeks to ≤ 12 months of age; and > 12 to < 72 months of age who will enroll into P1073 at a timepoint ≤ 1 week prior to initiating HAART

Inclusion Criteria

• Past or current documentation of a confirmed diagnosis of HIV-1 infection. Documentation of HIV-1 infection is defined as positive results from two samples collected at different time points. All samples tested must be whole blood, serum, or plasma.

  • Sample #1 may be tested by non-study public or PEPFAR programs. However, both the result and the assay date must be recorded in subject's chart. Source documentation (patient's medical record/chart, Ministry of Health (MOH) registers, laboratory results, etc.) must be available if requested.
  • Sample #2 must be performed in a CAP/CLIA-approved laboratory (for US sites) or in a laboratory that operates according to GCLP guidelines and participates in an appropriate external quality assurance program (for international sites).

  • For P1073, the subject may be enrolled before the result of Sample #2 is available. However, the subject will be taken off study should the 2nd result be negative.

    1. Acceptable tests when subjects are ≤ 18 months of age

       1. Sample #1 may be tested using any of the following: One HIV DNA PCR; One quantitative HIV RNA PCR (>5,000 copies/mL); One qualitative HIV RNA PCR; One total HIV nucleic acid test

          **If Sample #1 is positive, collect and test Sample #2.

       2. Sample #2 may be tested using any of the assays listed above for Sample #1.

    2. Acceptable tests when subjects are > 18 months of age

       1. Sample #1 may be tested using any of the following: Two rapid antibody tests from different manufacturers or based on different principles and epitopes; One EIA OR Western Blot OR immunofluorescence OR chemiluminescence; One HIV DNA PCR; One quantitative HIV RNA PCR (>5,000 copies/mL; One qualitative HIV RNA PCR; One HIV culture (prior to August 2009); One total HIV nucleic acid test

          **If Sample #1 is positive, then collect and test Sample #2.

       2. Sample #2 may be tested using any of the following: One EIA confirmed by Western Blot OR immunofluorescence OR chemiluminescence; One HIV DNA PCR; One quantitative HIV RNA PCR (>5,000 copies/mL); One qualitative HIV RNA PCR; One HIV culture (prior to August 2009;)One total HIV nucleic acid test

          • Rapid antibody tests are not allowed for sample #2

• Age: range is ≥ 4 weeks to < 72 months of age at time of HAART initiation.

  *All infants and children ≥ 4 weeks to < 72 months of age, who are about to initiate HAART according to National or WHO criteria, are eligible.

• HIV-infected infants and children who meet the ART guidelines of local programs or an IMPAACT or other protocol and who can be enrolled ≤ 1 week prior to starting HAART.
• No known active untreated opportunistic infection.
• Infants ≤ 12 months of age should have received BCG immunization and the date of BCG vaccine has to be known.
• Legal guardian able and willing to provide signed informed consent for participating in the IRIS study.

Exclusion Criteria

-Any clinically significant diseases (other than HIV infection) e.g. malignancy, auto-immune or inflammatory diseases requiring long-term immunosuppressive therapy, or clinically significant findings during the screening medical history or physical examination that, in the investigator's opinion, would compromise the outcome of this study.
