Timeline of HIV Disease in Haiti Before ART:Most important OIs Pulmonary TB : most common pre-AIDS manifestation occurring in 40% of the cohort by 6 years Most common AIDS illness: wasting syndrome, candida esophagitis, coccidia diarrhea Leading causes of death : wasting syndrome, TB, crytococcal meningitis, toxoplasmosis Deschamps MM et al.

Screening for TB at HIV VCT Centers • Study to evaluate risk of having TB among clients with cough seeking HIV testing at voluntary counseling and testing centers (VCTs). • Active TB was diagnosed in: • 30% of all VCT clients presenting with cough • Essential to offer same day screeningfor TB for persons with cough at HIV VCT centers • Patients with TB and cough can be rapidly identified for: • Treatment and • Prevention of TB transmission to immuno-compromised patients in waiting rooms • Patients dually infected with TB and HIV can be placed on isoniazid prophylaxis to prevent active TB Burgess A et al, AIDS:15: 1875-1879 2001
Screening of adults with cough for TB at GHESKIO VCT • 30% of all with cough have active TB • 55% of active TB cases are HIV+

Outcome of integration of HIV and TB From January 2005 to December 2006 in the MOH-GHESKIO network: • At VCT centers: • 9199 HIV-infected patients were evaluated for TB; • 2395 (26%)of them received care for TB • 2126 patients HIV positive received INH prophylaxis • 3768 patients with tuberculosis were tested for HIV; • 1213 (32%) of them were HIV positive
HIV/TB Challenges for Haiti • Interactions HIV/TB • HIV rate is 2-4 X higher in TB patients • Risk of developing active TB is 10X higher in HIV+. • INH prophylaxis and ART are both effective to prevent active TB in HIV+ • TB diagnosis: majority of TB patients are smear negative. Must do CXR • Most TB centers are staffed by nurses and auxiliary nurses • ART and TB therapyis complex • Preferable not to start HIV and TB therapy at the same time to avoid IRS • High toxicity, mortality; abandon rate, recurrence rate • MDRTB: higher association with HIV+ • Necessity to develop joint HIV/TB national programs 1) Necessity to screen for HIV in all TB centers and 2) Screen for TB at VCT centers. • HIV+ and PPD+ should have a CXR and sputum smear to rule out active TB • Place on TB therapy those with active TB and on INH those who do not have active TB • HIV+ should receive INH + RIF during entire duration of therapy 3) Develop joint ART/TB training for care of HIV + patients requiring both 4) Need to develop new category of medical staff: Physician assistant 5) Must develop effective referral system between HIV and TB centers 6) Need to have nationwide survey on importance of MDRTB and new centers to care for MDRTB
Perspectives • Complete integration between the national HIV and TB programs is necessary to curb both epidemics. • With PEPFAR support, plan to create at a public TB site (Siguenau): • Unit for HIV/TB management • Unit for MDRTB treatment
