NCT00004735

Brief Summary

The purpose of this study is to determine the number of newly formed CD4 cells in children who have taken anti-HIV drugs. The study will also evaluate the effectiveness of the new CD4 cells in producing an immune response to hepatitis A and tetanus toxoid vaccination. Study hypothesis: 1) Immunologic reconstitution of individuals who have less than 15% CD4 cells may or may not be associated with functional activity. 2) The functional immunologic responses to recall and newly experienced antigens may be different. 3) The functional responses to antigens delivered in vaccine format may be a function of CD4 level, viral load, or both.

Outcome Measures

Primary Outcomes (3)

  • A stimulation index of 3 or greater on at least 2 occasions to tetanus

  • positive serologic response to hepatitis A

  • four-fold increase over baseline in antibody titers for tetanus

Secondary Outcomes (3)

  • A stimulation index of 3 or greater on at least 2 occasions to hepatitis A and Candida

  • increase in CD4 cell percentage by 10% and absolute CD4 number by 150 cells/ml

  • development of any adverse events of Grade 3 or higher attributable to vaccination

Eligibility Criteria

Age2 Years - 24 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • HIV infected
  • CD4 percentage less than 15%
  • Beginning an anti-HIV drug regimen (HAART) that includes at least 3 drugs. Two of the drugs must be new to the patient. One of the new drugs must be a protease inhibitor or a nonnucleoside reverse transcriptase inhibitor (NNRTI). As of May 2005, patients who have previously taken NNRTIs will have the option of taking Fuzeon as an alternative component of their HAART regimen
  • Consent of parent or legal guardian
  • As of May 2005, females who become pregnant during the study can continue to participate as long as they become pregnant after receiving all vaccinations

You may not qualify if:

  • Active opportunistic (AIDS-related) or bacterial infection
  • Cancer
  • Immunity to hepatitis A
  • Severe drug toxicity
  • Previous severe or allergic reaction to tetanus vaccine
  • Taking IVIG, IL-2, or other drugs which affect the immune system
  • Taking hydroxyurea
  • Pregnancy at screening visit
  • Pregnancy before all vaccinations have been administered
