Brief summary
The purpose is to perform tonometry in HIV-infected adults before and after switching their HIV treatment from Kivexa to Truvada (or from Abacavir to Tenofovir). Hypothesis: that markers of cardiovascular function (as measured by applanation tonometry) will improve in patients switching from ABC-3TC to TDF-FTC.
Interventions
using applanation tonometry to evaluate cardiovascular function in adults with HIV infection switching from ABC-3TC (Kivexa) to TDF-FTC (Truvada) or from ABC (abacavir) to TDF (tenofovir). Kivexa is a combination HIV pill of Abacavir and lamivudine and Abacavir alone is one of the two drugs in Kivexa. Truvada, another combination pill that contains the drugs tenofovir and emtricitabine and Tenofovir alone is one of the two drugs in Truvada. Truvada and Tenofovir are the two drugs to be used in this study. This is a 24 week study Truvada dose is 1 x 300mg/200mg tablet, once daily, oral for 24 weeks. Tenofovir dose is 1 x 300mg tablet, once daily oral for 24 weeks.
