[Acanthamoeba keratitis. Epidemiologic and parasitologic study].
The amebic keratitis with Acanthamoeba are until now rare, but however increasing as their diagnosis is better, and the contact lens wearers more numerous. The authors present the clinical and parasitological features of cases they did diagnose since 1986. In the immunological sphere, the T4 lymphocytes were 20% less than the normal for the first patient, and the third one had a very low level of immunoglobulins A. In the evolution sphere, the first one did received a keratoplasty; the second one has been successfully treated with propamidine isethionate; for the third one, the treatment with propamidine isethionate was nonuseful and a keratoplasty which was finally performed did show off numerous amebic cysts. In the parasitologic sphere, Acanthamoeba polyphaga was isolated from the first case, Acanthamoeba quina from the second one and Acanthamoeba lugdunensis from the last one. These last two cases are the first which did permit to isolate these amoebae, morphologically near to the first species.
