  Purpose

A case-control study to look at hypersensitive and tolerant individuals matched for HLA genetic predisposition, when considering predictors of drug hypersensitivity.The study aims to identify the immunological factors increasing the risk of drug reactions in HIV positive individuals.

Biospecimen Retention:   Samples With DNA

plasma, DNA


Enrollment: 0
Study Start Date: August 2005
Groups/Cohorts
Drug hypersensitive group
HIV positive patients with a history of a Hypersensitivity Reaction to the antiretroviral medications Nevirapine, Abacavir or Efavirenz
Drug tolerant group
HIV positive patients selected based on drug exposure greater than 2 weeks and tolerance to to Abacavir or Nevirapine.

Detailed Description:
  1. To determine in a case control study clinical parameters associated with drug HSR to abacavir, nevirapine and efavirenz in HIV infected subjects.
  2. To measure functional and numerical differences in DC populations and responses to TLR ligands in patients with HSR and tolerant subjects sharing genetic markers for susceptibility to HSR.
  3. Identify the role of different DC populations in the development of abacavir reaction by mixing and depletion studies in sensitized subjects and in in vitro assays for abacavir hypersensitivity.
  4. To measure T cell parameters including T cell viability in culture, and expression of fas and fasL on blood mononuclear cells in HIV infected controls and HSR patients.
  5. To measure blood T cell populations including drug reactive T cells and T regulatory cells in tolerant and reactive subjects with genetic susceptibility to Abacavir and Nevirapine HSR.
