Chloroquine susceptibility of Plasmodium falciparum in Haiti. 1983

R Magloire, and P Nguyen-Dinh

In January and February 1982, in vivo and in vitro studies of the chloroquine sensitivity of Plasmodium falciparum were conducted in Port-au-Prince, Haiti. Of 19 infections tested in vivo using the WHO extended test, all but one were susceptible to the drug; the remaining case showed a recurrence of parasitaemia on day 28. Of the 19 corresponding 48-hour in vitro tests, 16 provided interpretable results; 12 tests demonstrated sensitivity to the drug, while in the remaining 4, parasite multiplication was inhibited only at drug concentrations higher than that previously accepted as indicative of sensitivity. (These four included the isolate from the patient who had a recurrence of parasitaemia on day 28.) While these results provide no absolute demonstration of chloroquine resistance, they underline the need for close monitoring of the susceptibility to chloroquine of P. falciparum in Haiti.

D006205	Haiti	A republic in the Greater Antilles in the West Indies. Its capital is Port-au-Prince. With the Dominican Republic it forms the island of Hispaniola - Haiti occupying the western third and the Dominican Republic, the eastern two thirds. Haiti belonged to France from 1697 until its rule was challenged by slave insurrections from 1791. It became a republic in 1820. It was virtually an American protectorate from 1915 to 1934. It adopted its present constitution in 1964 and amended it in 1971. The name may represent either of two Caribbean words, haiti, mountain land, or jhaiti, nest.
