Using Drug Levels and Drug Resistance Testing to Select Effective Anti-HIV Drug Combinations in Patients With Drug-resistant HIV

Brief Summary
Because people infected with HIV strains that are resistant to anti-HIV drugs have fewer effective treatment options, selecting an effective anti-HIV drug combination is difficult. A combination of protease inhibitors (PIs), when added to a patient's current anti-HIV therapy, may decrease viral load and increase drug activity. Tests that measure drug levels in the blood and tests to evaluate the drug resistance of HIV may also be helpful in choosing the best anti-HIV drug combination for a patient. This study will determine whether using these tests to choose a drug combination and adding PIs to that combination will improve the patient's response to anti-HIV therapy.
