* the most common AIDS-defining condition & the most common cause of death in patients with AIDS
Laboratory
- CD4 count: opportunistic infections in untreated HIV1 patients generally occur with CD4 count drops below 200/uL[1]
Management
- prophylaxis
- Pneumocystis jirovecii
- CD4 count < 200/uL
- Bactrim DS QD or 3 times weekly[1]
- toxoplasmosis
- CD4 count < 100/uL with postitive serology
- Bactrim DS BID
- Mycobacterium avium complex (MAC)
- CD4 count < 50/uL
- azithromycin 1200 mg/week
- tuberculosis
- positive tuberculin skin test or IFN-gamma release assay
- INH 300 mg/day for 9 months
