The clinical and parasitological characteristics of the first naturally acquired malarial infection have rarely been documented in humans. When 243 migrants from non-endemic Java were followed from the day of their arrival in Indonesian Papua, 217 (89%) were found to become infected with Plasmodium falciparum and/or P. vivax before they were lost to(More)
We compared placebo and dexamethasone (initial dose, 3 mg/kg; total, 11.4 mg/kg per 48 h) in a double-blind trial involving 10 stuporous and 28 comatose patients with cerebral malaria. Patients were 18 mo to 42 y of age (geometric mean, 10.2 y), and the 19 patients in each group were comparable on admission. All patients received intravenous quinine(More)
BACKGROUND During the period of 1996-1999, we prospectively monitored 243 Javanese adults and children after arriving in Papua, Indonesia, and microscopically documented each new case of malaria by active surveillance. METHODS In a randomized, open-label, comparative malaria treatment trial, 72 adults and 50 children received chloroquine for each incident(More)
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,(More)
A malariometric survey was conducted in 14 villages of Sekotong district, in Lombok, Indonesia during October 1994. Point prevalence of malaria ranged from 0% to 15% in the surveyed villages, averaging 6% overall, and Plasmodium falciparum accounted for 63% of the infections. Forty-nine patients with uncomplicated malaria and parasite counts ranging from 40(More)
The epidemiology of infection by Plasmodium falciparum and P. vivax was investigated among Javanese migrants to an endemic region of Papua, Indonesia. A cohort of 243 migrants from Java was followed for malaria in a new settlement village in the endemic Armopa area of north-eastern Papua, beginning on the day each migrant arrived in the village. The(More)
We carried out a series of malaria studies in Robek , Flores, Indonesia, a coastal village of 900 farmers and fishermen where malaria is hyperendemic by parasite rate and holoendemic by spleen rate. The studies showed that: (i) 28 of 31 isolates (90%) of Plasmodium falciparum were resistant to chloroquine in vitro, (ii) 3 of 12 isolates (25%) were resistant(More)
The sensitivity of Plasmodium falciparum infections to pyrimethamine-sulfadoxine was studied in 18 Indonesian patients in Jayapura, Irian Jaya. In 16 of the 18 patients parasitaemia was cleared by day 6 and the patients remained without parasitaemia through day 28. Two of the 18 patients had late recrudescences consistent with RI-type resistance; one each(More)
2 of 36 Plasmodium falciparum infections were resistant (RII and RIII) in vivo to the combination of mefloquine (M) and sulfadoxine-pyrimethamine (SP) in Jayapura, Irian Jaya, Indonesia. Expected absorption of mefloquine and pyrimethamine was confirmed in the one resistant patient from whom sera were available, and the isolate from this patient was(More)
