Eligibility Criteria
You may qualify if:
- Confirmed HIV positive after voluntary counseling and testing
- Aged \>18-60years of age
- PI-naïve (NNRTI intolerance/failure) or PI experience ( TB developed during on salvage regimen) without prior PI mutation
- Any CD4 cell count
- ALT \<5 times ULN
- Serum creatinine \<1.4 mg/dl
- Hemaglobin \>7 mg/L
- TB is diagnosed and planned to receive stable doses of rifabutin containing anti-TB therapy for at least another 4 week period after initiation of ART
- No other active OI (CDC class C event), except oral candidiasis or disseminated MAC
- Body weight \>40kg
- Able to provide written informed consent
You may not qualify if:
- Current use of steroid (except short course steroid for IRIS) and other immunosuppressive agents.
- Current use of any prohibited medications related to drug pharmacokinetics.
- Patients with current alcohol or illicit substance use that in the opinion of the site Principal Investigator would conflict with any aspect of the conduct of the trial.
- Unlikely to be able to remain in follow-up for the protocol defined period.
- Patients with proven or suspected acute hepatitis. Patients with chronic viral hepatitis are eligible provided ALT, AST \< 5 x ULN.
- Karnofsky performance score \<30%
- TB meningitis and bone/joints ( due to longer period of anti TB drug)
- Pregnancy
- Patient choose to use efavirenz, not LPV/r. However, in ART naïve, EFV is allowed after intensive PK of LPV/r and rifabutin at week 2-4.
