ABSTRACT

A recent malaria epidemic in the Menoreh Hills of Central Java has increased concern about the re-emergence of endemic malaria on Java, which threatens the island's 120 million residents. A 28-day, in-vivo test of the efficacy of treatment of malaria with antimalarial drugs was conducted among 167 villagers in the Menoreh Hills. The treatments investigated, chloroquine (CQ) and sulfadoxine-pyrimethamine (SP), constitute, respectively, the first- and second-line treatments for uncomplicated malaria in Indonesia. The prevalence of malaria among 1389 residents screened prior to enrollment was 33%. Treatment outcomes were assessed by microscopical diagnoses, PCR-based confirmation of the diagnoses, measurement of the whole-blood concentrations of CQ and desethylchloroquine (DCQ), and identification of the Plasmodium falciparum genotypes. The 28-day cumulative incidences of therapeutic failure for CQ and SP were, respectively, 47% (N = 36) and 22% (N = 50) in the treatment of P. falciparum, and 18% (N = 77) and 67% (N = 6) in the treatment of P. vivax. Chloroquine was thus an ineffective therapy for P. falciparum malaria, and the presence of CQ-resistant P. vivax and SP-resistant P. falciparum will further compromise efforts to control resurgent malaria on Java.

ABSTRACT

A community-based prospective study was performed from December 1993 through March 31, 1994 in Indonesia in children less than five years of age. Enterotoxigenic Escherichia coli (ETEC) was identified in diarrheic stool by colony hybridization assay, using toxin probes, and this bacterium was isolated from 19% of 340 episodes of diarrhea. Sixty-one percent of ETEC produced heat-labile toxin (LT) only, 325 LT and heat-stable toxin (ST), and 75 ST only. The age-specific incidence rates of diarrhea among children 0-1 and 2-3 years of age were 77% and 61%, respectively, during the study period; ETEC was isolated from 26% of children 0-1 years of age versus 53% for children 2-3 years of age. As many as seven episodes of diarrhea were repeatedly experienced by a single child during the four-month study period; however, only two children had more than one episode of known ETEC-associated diarrheal disease during the period of observation.
