Brief Summary
This study will investigate what factors may lead to the development of immune reconstitution syndrome (IRIS) in HIV-infected patients and what the outcome is after IRIS. It will also seek to better define and describe the syndrome. IRIS is a condition that can occur in HIV-infected people following the start of antiretroviral therapy. The sudden improvement of immune function with this therapy can cause an unexpected worsening of diseases the patient already has, such as tuberculosis or fungal infections, and development of fever, enlarged lymph nodes or other complications, or even uncover a previously silent disease. HIV-infected people who are at least 18 years old, whose CD4+T cell count is 100 cells per microliter or less, and who have not previously been treated with combination antiretroviral therapy or have taken the drugs for less than 3 months and more than 6 months before screening for this study may be eligible to participate. Candindates must also live within the wider DC area so that acute problems after therapy initiation will be evaluated at NIH. Candidates are evaluated before starting therapy with a medical history and physical examination, blood and urine tests, electrocardiogram, chest x-ray and CT scan of the chest, tuberculin skin testing, apheresis, and possibly an intestinal (gut) and lymph node biopsy (surgical removal of a small piece of tissue for microscopic examination). For apheresis, blood is collected through a needle in an arm vein and spun in a machine that separates the blood components. The white blood cells and plasma are removed, and the red cells and platelets are returned through the same needle or through a needle in a vein in the other arm. Participants have a complete history and physical examination and additional blood tests, including genetic studies, upon entering the study. They start taking anti-HIV medications, prescribed according to the current standard of care, as well as medications to treat other infections, and treatment of IRIS, if needed. The study lasts about 4 years. Patients return to the clinic at 2, 4, 8 and 12 weeks after the entry visit, then every 12 weeks (about every 3 months) until week 48 (the first year), and then every 16 weeks (about every 4 months) until the end of the study. At most visits, patients have a medical history, physical examination and blood and urine tests, including CD4+T cell count and HIV plasma viral load measurement. Apheresis is also done at weeks 24 and 48 and then once every 48 weeks. Intestinal and lymph node biopsies (optional) are also done at weeks 24 and 48. A syphilis test and PAP smear (for women) are done yearly. and plasma, cells and serum are stored at almost every visit for immunologic studies.

Outcome Measures
Primary Outcomes (2)
To identify baseline predictors of IRIS within 6 months of HAART initiation prospectively in a group of HIV-1 infected patients with advanced disease who are starting antiretroviral therapy.
During the data analysis phase at the end of the study
To evaluate the immunopathogenesis of IRIS with the goal to identify more appropriate targets for future therapeutic interventions.
During the data analysis phase at the end of the study
Secondary Outcomes (3)
Evaluate the baseline clinical and immunological characteristics ofindividuals who develop IRIS and compare them with those who do not.
During the data analysis phase at the end of the study
To study the incidence and clinical manifestations of IRIS prospectively in a group of HIV-1 infected patients with advanced disease who are initiating antiretroviral therapy.
During the data analysis phase at the end of the study
To evaluate the impact of IRIS on the risk of subsequent death (attributable mortality).
During the data analysis phase at the end of the study
Eligibility Criteria
You may qualify if:
- For the National Institutes of Health (NIH)/US site: HIV-1 infection, as documented by OraQuick rapid test using venipuncture whole blood, or fingerstick whole blood done at screening; or by reactive enzyme-linked immunosorbent assay (ELISA) and Western Blot as determined by NIH Clinical Pathology Laboratory or Leidos Biomedical Research, Inc. Monitoring Laboratory. HIV infection as determined by an outside Clinical Laboratory Improvement Amendments (CLIA)-approved laboratory facility" will be accepted for enrollment and verified by a standard HIV-1 ELISA with Western Blot at NIH.
- For Keny Medical Research Institute/Walter Reed Project Clinical Research Center (KEMRI/WRP CRC)/Kenya site: HIV-1 infection will initially be diagnosed based upon two, serial rapid HIV tests according to Kenya Ministry of Health (MOH) guidelines. Volunteers entering this study will have HIV infection confirmed by two serial rapid HIV test in accordance with Kenya MOH guidelines and testing algorithm followed by a confirmation with a Western Blot using FDA approved-kits. Samples from participants with discrepant results (between the results from other institution and KEMRI/WRP-CRC laboratory) and/or indeterminate/negative Western Blot will be subjected to a nucleic acid assay i.e. DNA or RNA PCR. For Thailand, HIV-1 screening and confirmatory testing will be based on 3, HIV tests according to the Thai Ministry of Public Health guidelines. The subjects will initially be tested with a chemiluminescent microparticle immunoassay (CMIA) method that detects both HIV antigen and antibody. Confirmatory testing of HIV reactive samples by two different antibody detection methods will follow. Positive results by all three methods confirm HIV diagnosis. Discrepancy between the tests will require a nucleic acid detection method to confirm HIV diagnosis.
- No previous treatment with potent combination anti-retroviral therapy (ART), defined as any protease inhibitor (PI)-based or non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen, or even triple nucleoside reverse transcriptase inhibitors (NRTI)-based regimen, consisting of at least three antiretroviral drugs (including a boosted PI with NNRTI combination). Patients with limited use of ART (less than 12 weeks duration) more than 24 weeks before screening will be eligible for study participation.
- Screening CD4+ cell count less than or equal to 100 cells/mm(3). \* Note: CD4 \< 100 cells/microL from an outside or the site s laboratory within 8 weeks prior to screening can be accepted as the screening value.
- Residence within the wider Washington D.C. area (approximately within a 120-mile radius from the NIH Bethesda campus) for the National Institutes of Health/US site and residents of the Kericho District Hospital catchment area, an approximate 93-mile (150 kilometers) radius, for the KEMRI/WRP CRC/Kenya site. Residence within the Bangkok Metropolitan area and nearby provinces are allowed to participate (approximately 120-mile radius from each of the clinical sites)
- Men and women age greater than or equal to 18 years.
- Ability and willingness of subject or legal guardian/representative to understand study requirements and give informed consent.
- For the NIH/US site: Participants should have a primary care physician or will need to agree to find one during the first 24-48 weeks on study. For the KEMRI/WRP/Kenya site: Participants must be enrolled in the Kericho District Hospital HIV Clinic. For the two Thailand clinical sites: participants must be enrolled in the HIV clinic at either of the sites.
You may not qualify if:
- Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements.
