Purpose
The purpose of this study is to measure the decay characteristics of HIV in the blood of patients after taking a combination of anti-HIV drugs, which includes a new class of anti-HIV drug, an integrase inhibitor. This study explores how this new combination of therapy reduces virus in various compartments of the body and immune system.

Detailed Description:
The study is an open-label study of 3-years duration. This study will be conducted at 4 study sites in Sydney, Australia. Sixteen participants will be recruited comprising 8 participants diagnosed with primary HIV infection (Cohort A) and 8 individuals with chronic HIV infection (Cohort B). All patients must be antiretroviral therapy (ART) naïve and will commence a regimen of combination ART consisting of tenofovir disoproxil fumarate and emtricitabine (TDF/FTC; Truvada) plus the integrase inhibitor, raltegravir. Subjects will be followed for three years with intensive quantification of both plasma RNA and cell associated DNA viral species.

Cohort A: Primary HIV infection:
Documented acute or early infection diagnosed by:
Acute infection:
< 3 bands on Western Blot and any one of: i. positive p24 antigen ii. positive proviral DNA
Early infection:
i. Positive detuned or BED ELISA result OR ii. Previously negative serology within 6 months of confirmed positive serology.
Cohort B: Chronic HIV infection:
Documented HIV-infection of at least 12 months duration.
Exclusion Criteria:
- Pregnancy or breastfeeding.
- Receipt of investigational products within 1 month of study entry.
Receipt of any of the following within 6 months of study entry:
- interferon alpha or gamma
- oral corticosteroids (inhaled or topical corticosteroids are permitted)
- cyclosporin
- alkylating agents
- other immunosuppressive agents
- rifampin
- phenytoin
- phenobarbital
- Documented genotypic (IAS 2007) resistance to tenofovir or emtricitabine from any HIV drug resistance test.
- Any medications contraindicated with Truvada or raltegravir.
- Significant intercurrent illnesses apart from HIV infection such as viral hepatitis (diagnosed by core hepatitis B antigen and/or positive hepatitis B PCR or positive hepatitis C PCR) or any other condition which in the opinion of the investigator would compromise participation in the study.
- History of non-traumatic osteoporotic fracture.
