Raltegravir vs. Atazanavir in Combination With Truvada® for the Treatment of Antiretroviral naïve HIV Infected Patients

Overview

This is a pilot that will evaluate two regimens for treating HIV infected patients that haven't been on treatment before. HIV/AIDS patients may have an increased risk of myocardial infarction and antiretroviral therapy used may contribute to this. We will evaluate virological, immunological and cardiovascular effects of two HIV treatment regimens.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: December 2012

Detailed Description

We will check blood studies used to evaluate HIV patients response to therapy including CD4 count and HIV viral load test. We will check routine safety labs done on HIV patients and also check homocysteine levels and creatine kinase level. We will evaluate homocysteine and IL6 levels at baseline, week 48, and week 96.
