Purpose
This study has been designed to evaluate a new oral test for therapeutic monitoring of HIV/AIDS patients that are receiving the combination Anti-Retroviral Therapy (cART). The test will measure saliva-based Stress Response Profiling(SRP) biomarkers using laboratory assays. Results of the test will show if HIV/AIDS patients successfully responded to cART. Preliminary studies showed that SRP biomarkers were strongly increased in cART-unresponsive AIDS patients. However, the diagnostic accuracy of the oral test, patients will be recruited to donate saliva: AIDS patients responsive or unresponsive to cART, and controls (acute or early HIV patients, and HIV-negative patients with hepatitis).
The saliva samples will be used to measure SRP biomarker concentrations. Results will show whether the biomarker measurements provide accurate and specific diagnostics for ART response.

Early HIV:
- A positive antibody response (western blot or ELISA) with a documented negative serological test or plasma HIV-1 RNA within the past 12 months or a positive ELISA and a negative de-tuned ELISA within 30 days of a positive ELISA specimen in an untreated person with no clinical or immunological evidence of advanced HIV disease (CD4 count >200 cells/mm3 or >14%)
Group 4, HIV-negative Hepatitis-positive
- HIV test negative (western blot, ELISA or viral load)

Exclusion Criteria:
- Pregnant or lactating women
- Non-adherent patients
- Any conditions which will affect saliva production: e.g. Sjogren's syndrome or chronic mouth dryness
- Cytotoxic chemotherapy, interferon treatment, or radiation therapy within the preceding 3 weeks
- Active alcohol or substance abuse (narcotics or other controlled substances) within 6 months prior to the saliva sampling
- Significant psychiatric illness that in the opinion of the principle investigator might interfere with making an informed decision
- Incapable to give informed consent
