title: Therapeutic efficacy of sulfadoxine-pyrimethamine in uncomplicated Plasmodium falciparum malaria 3 years after introduction in Mpumalanga.
abstract: OBJECTIVE
  To assess therapeutic efficacy of sulfadoxine-pyrimethamine (SP) in treatment of uncomplicated Plasmodium falciparum malaria 3 years after introduction in Mpumalanga, South Africa.
  
  
  METHODS
  Tonga district with a population of 116,418 and subject to seasonal malaria, with an average annual incidence of 3,200 cases.
  
  
  METHODS
  One hundred and nineteen malaria patients presenting to a sentinel surveillance clinic and recruited according to World Health Organisation (WHO) criteria.
  
  
  METHODS
  Patients satisfying WHO inclusion criteria were treated with a single oral dose of SP and the response of infection to treatment in each patient was routinely monitored clinically and parasitologically on days 1, 2, 3, 7, 14, 21, 28 and 42 post-treatment. One hundred and ten patients completed follow-up to day 42 or evidence of clinical or parasitological failure.
  
  
  RESULTS
  The cure rate at day 42 was 93.6% (103/110). Two patients (1.8%, RII) were early treatment failures on day 3, while recrudescence (4.5%, RI) occurred in 5 patients on day 28 (N = 3) and on day 42 (N = 2).
  
  
  CONCLUSIONS
  In Mpumalanga P. falciparum remains sensitive to SP, with no significant difference between the baseline cure rate (94.5%) and the cure rate in the present study (93.6%).
