title: [Hepatic amebiasis: study of 152 cases].
abstract: The purpose of this study was to describe and analyse retrospectively the clinical, serological, anatomical and evolutive features of 152 cases of hepatic amebiasis in young adults, treated and followed up in France from 1969 to 1983. The disease was revealed 3 times out of 4 by tender hepatomegaly with fever, but only in 6 cases by complications. Serological tests (immunofluorescence or hemagglutination) were always positive for amebiasis, whereas Entamoeba histolytica was absent from stools in 96.7 p. 100 of the cases. Hepatic amebiasis always caused a hepatic abscess: in these cases, the superiority of ultrasonography over all other diagnostic methods was confirmed, especially concerning the detection of multiple abscesses (47 p. 100). Complete recovery was obtained by medical treatment in 117 cases, either alone (98 cases), or combined with needle aspiration (19 cases). Nitro-imidazoles are the simplest treatment, but nevertheless in 5 cases they were not effective. These patients were then treated with dehydroemetine, associated in 2 cases with surgery. Four patients relapsed at mid or long-term after apparent recovery, in the absence of any obvious reinfection. A significant correlation between the course of the treated disease and the size and number of abscesses was demonstrated: it was possible to define a group characterized by a slow and/or complicated course (with single abscess of the right lobe whose diameter is equal to or greater than 10 cm, or multiple abscesses). The pathogenesis of hepatic amebiasis is not yet fully understood.
