[Frequency of amebiasis and other intestinal protozoal diseases. An epidemiological study with the aid of MIF technic].

Advantages and disadvantages of various laboratory techniques used for the diagnosis of intestinal protozoa are discussed. The importance of a correct parasitological diagnosis is emphasized. The MIF procedure has been investigated with regard to its reliability and found to be very effective due to its high diagnostic yield and reproducibility in repeated examinations. The incidence rates found in our material agreed well with those in the literature, thus enhancing the value of the MIF procedure. The feces of 1005 persons returning from the tropics during the first 8 months of 1975 have been examined by the MIF technique and assessed for intestinal protozoa. Apathogenic amebae were found four times as often as E. histolytica. The incidence was 52.7/1000 for E. histolytica and 70.6/1000 for Giardia lamblia. Multiple parasitosis is often diagnosed. E. histolytica is very likely to be encountered when two or three apathogenic amebae are present.

Hemolytic uremic syndrome associated with Entamoeba histolytica intestinal infection.

Amebiasis secondary to Entamoeba histolytica (E. histolytica) continues to be a major source of morbidity and mortality worldwide, mainly in developing countries. An association between amebic dysentery and hemolytic uremic syndrome (HUS) has been mentioned, but a cause-and-effect relationship has never been confirmed. We report the case of an 11-year-old healthy white female who developed severe bloody diarrhea after drinking contaminated unboiled water, developing classic HUS and requiring acute intermittent hemodialysis. The etiological study confirmed numerous cysts and hematophagous trophozoites of E. histolytica on stool smear, but without evidence of other pathogens. This report contributes to the concept that classic post-diarrheal HUS, usually related to colitis secondary to enterohemorragic Shiga-toxin producing Escherichia coli (E.coli) strains, may be associated with other pathogens, including E. histolytica. Additional information regarding mechanisms of virulence of E. histolytica and host immunological reaction is needed to clarify the temporal association of these two disorders (HUS and amebiasis).
