Invasive amoebic colitis in AIDS patients

Invasive Amebiasis as an Emerging Parasitic Disease in Patients With Human Immunodeficiency Virus Type 1 Infection in Taiwan

“…Although the comparison groups were not perfectly matched to the HIV-infected persons, we believe that this is not a critical issue because the study was conducted in a single medical center in an endemic region for amebiasis. 23 There are only a few scattered case reports [16][17][18][19][20][21][22] of invasive amebiasis among HIV-infected persons in Western countries. Lowther and associates 11 conducted a large retrospective review of the medical diagnoses of more than 34 000 HIV-infected persons.…”

“…Investigators in Japan and Italy found a higher prevalence of antibody to E histolytica in homosexual men with or without HIV infection. [12][13][14][15] Case reports [16][17][18][19][20][21][22] from various countries describe invasive amebiasis in homosexual men with or without HIV infection. Recent reports from Taiwan 23 and Korea 24 describe cases of invasive amebiasis in homosexual men.…”

Invasive amoebiasis: an emerging parasitic disease in patients infected with HIV in an area endemic for amoebic infection

“…E. histolytica trophozoites and cysts were detected in the stool specimens of two patients. The main presenting symptoms of IA were fever (13), chronic diarrhoea (12), and abdominal pain (five). In two patients with fever and chronic cough, IA was complicated by pleural effusion in addition to liver abscess; the initial diagnosis was bacterial empyema and liver abscess was found incidentally by chest sonography.…”

“…Similarly, cases of IA are only rarely or never reported in HIV-infected patients, either from developed [10][11][12][13][14][15] or developing countries [16][17][18][19][20]. The reason remains unclear why IA is rare in HIV-infected patients despite their declining T-cell immunity, the major immunity against E. histolytica infection [2,21].…”

Invasive amoebiasis in two patients with AIDS and cytomegalovirus colitis

“…Blanshard et al reported an AIDS patient who died from severe enterocolitis and peritonitis. While stool examinations for pathogens, including amoebae, were negative, a rectal biopsy showed histologic evidence for invasive amoebiasis (4). A third patient was reported from Japan (14).…”
