Eligibility for co-trimoxazole prophylaxis among adult HIV-infected patients in South Africa

Abstract

Co-trimoxazole (fixed-dose trimethoprim-sulfamethoxazole) is a broad-spectrum antibiotic used to prevent opportunistic infections in patients with HIV infection. Primary prophylaxis with co-trimoxazole has been shown to decrease hospitalisation, morbidity and mortality among people living with HIV, primarily by decreasing rates of malaria, pneumonia, diarrhoea, Pneumocystis pneumonia, toxoplasmosis and severe bacterial infections.Co-trimoxazole is inexpensive and widely available. In standard adult treatment guidelines and essential medicine lists in South Africa (SA), the current recommendation is that co-trimoxazole should be provided for HIV-infected patients with a CD4+ count ˂200 cells/µL, HIV/tuberculosis (TB) co-infection and/or advanced HIV disease (World Health Organization (WHO) stage 3 or 4).
