Brief Summary
At least three studies in sub-Saharan Africa have demonstrated a decrease in morbidity or mortality among HIV-infected adults who took daily cotrimoxazole (trimethoprim sulfamethoxazole) \[CTX\] prophylaxis. Because of the demonstrated beneficial effect, high tolerability and low cost of CTX, the United Nations Programme on HIV/AIDS (UNAIDS) recommends that HIV-infected persons with symptomatic HIV or depressed CD4 counts receive daily CTX. The effect of this recommendation on subsequent development of antimicrobial resistance to antifolates among important pathogens needs to be evaluated. The investigators measured the change in the prevalence of markers of antifolate resistance among P. falciparum, and the change in the prevalence of CTX resistance among S. pneumoniae, and E. coli in HIV-infected individuals receiving CTX daily prophylaxis. In addition, the investigators measured the change in the prevalence of naso-pharyngeal or oro-pharyngeal carriage of CTX resistant S. pneumoniae among children living in households where an HIV-infected adult was receiving CTX daily prophylaxis.

Outcome Measures
Primary Outcomes (3)
Change in Plasmodium falciparum molecular markers of antifolate resistance before and while taking daily CTX
Change in nasopharyngeal pneumococcal resistance before and while taking daily CTX, and among children living in households where adults are taking daily CTX
Change in commensal E. coli resistance before and while taking daily CTX
Secondary Outcomes (7)
To measure CTX-resistance among Salmonella and other enteric bacterial pathogens in patients with diarrhea in the study area
To assess the efficacy of sulfadoxine-pyrimethamine (SP) treatment of breakthrough P. falciparum parasitemia and clinical malaria among HIV-infected persons taking daily CTX prophylaxis
To measure sulfa metabolite levels in HIV-infected persons receiving daily CTX who develop a drug reaction, to determine if differing rates of metabolism contribute to the development of adverse reactions
To assess the effect of daily CTX prophylaxis on the etiology of diarrheal diseases in HIV-infected persons
To evaluate the serotype distribution of and immune response to colonizing pneumococci
