Preventive therapy for tuberculosis in patients with HIV is effective, but it has not been widely implemented in moderate or high-burden settings. The authors assessed the effect of widespread use of isoniazid preventive therapy on rates of tuberculosis and death in people with HIV in Brazil. They conclude that operational training aimed at increasing tuberculosis screening, provision of tuberculin skin tests, and use of isoniazid preventive therapy in Brazilian HIV clinics significantly reduced incident tuberculosis and death. Thus, scale-up of preventive therapy for HIV-infected patients in settings of moderate tuberculosis incidence is achievable and should be widely implemented in Brazil and elsewhere.
