A case of fulminant amebic colitis
with multiple large intestinal perforations.
Amebic colitis and other forms of amoeba parasites are second only to malaria in terms of protozoa-associated mortality.
The combined prevalence of amebic colitis and amebic liver abscess is estimated at 40 to 50 million cases annually worldwide, resulting in 40,000 to100,000 deaths every year.
However, the reasons amebiasis is increasing and the actual prevalence of amebic colitis in daily clinical practice have not been fully clarified.
To address these issues, we clarified annual changes in prevalence and risk factors for amebic colitis among persons who had undergone endoscopy.
Amebic colitis was suspected on the basis of endoscopic findings, such as erythema, edematous mucosa, erosions, white exudates, and ulcers (Figure 1) (22,23).
When amebic colitis was diagnosed, the physician asked the patient directly for information about the route of amebic infection.
Of the 5 patients, 3 had amebic colitis
and 2 had amebic liver abscesses, all were MSM, 4 were HIV-infected, mean age was 45 years (range 35-57 years), and median CD4 count was 713 cells/[mm.sup.3] (Table).
