Generally, amebic colitis is localized around the mucosal membrane and often accompanied by diarrhea and abdominal pain. We describe a patient with a history of rheumatoid arthritis who had received prolonged steroid therapy. The patient complained of breathing difficulties because of rheumatoid lung disease. Although the patient was given antibacterial agent, the symptoms did not improve until death. We did an autopsy and found that he had fulminant amebic colitis, although the patient was not previously examined. Histochemical analysis revealed severe inflammation and full-thickness necrosis of the colon by ameba, suggesting the involvement of ameba in the progression of the overall condition.

The clinical and pathological features of human intestinal spirochetosis (HIS) are not well known. Here we report 55 patients with HIS who were diagnosed at our institution during the past 5 years. Seven patients presented with symptoms such as abdominal pain or diarrhea, while the others were incidentally diagnosed during screening colonoscopy. Most patients had non-specific endoscopic findings, including intestinal edema or erosion. The diagnosis of HIS was histologically confirmed via hematoxylin and eosin staining, periodic acid-Schiff staining, and/or immunohistochemistry using anti-Treponema pallidum antibody. Among the 55 patients, five were diagnosed with diseases other than HIS (amoebic colitis, three;ulcerative colitis, one). Sixteen patients were treated with either amoxicillin or metronidazole;only metronidazole proved to be effective. The clinical significance of asymptomatic HIS remains unknown. Some case reports suggest a risk for increased severity in patients with immunodeficiency and/or sexually transmitted diseases. Therefore, aggressive treatment for HIS should be considered, particularly in high-risk patients.

Amoebiasis, caused by the intestinal protozoan Entamoeba histolytica, though a relatively common parasitic disease in the tropical and subtropical regions, is uncommon in the developed countries. In these countries, as amoebic colitis shares similar clinical symptoms and endoscopic features with inflammatory bowel disease (IBD), these cases can be easily unrecognized and misdiagnosed. In this case report, we discuss the case of an adult patient with invasive intestinal amoebiasis, who was initially managed as Crohn's disease on corticosteroid treatment and subsequently rapidly deteriorated and developed multiple perforations in the colon and ileum. Despite total colectomy followed by resection of the small bowel, he died of multiple organ failure and sepsis within two months of his initial clinical presentation of diarrhea with abdominal pain. The learning point of this case is that invasive intestinal amoebiasis should be considered as a differential diagnosis at the first clinical adult presentation of IBD-like symptoms despite suggestive endoscopic findings of Crohn's like ulcers. Regardless of negative endoscopic biopsies, due to the low sensitivity of microscopic examination, serology test for antibody and molecular test for Entamoeba DNA are recommended for accurate detection and identification of Entamoeba species, especially in the high risk populations with recent travel to endemic zones and for patients with immunosuppression and comorbidities such as diabetes mellitus, tuberculosis, alcoholism, HIV/AIDS and in pregnant women. Amoebiasis should be completely ruled out prior to corticosteroid administration, to avoid severe complications such as fulminant intestinal amoebiasis which is associated with an inherently high mortality.

Amoebic colitis, caused by ingestion of water or food contaminated with the protozoan Entamoeba histolytica, can progress to a fulminant colitis. Computed tomography (CT) findings reported in the literature on this type of colitis are sparse. We present a 59-year-old male patient with a one-week history of progressive abdominal pain, abdominal distension and associated watery and bloody diarrhoea. A CT scan revealed deep ulcerations with submucosal and intramural tracking of contrast. Colonoscopy and biopsy confirmed a diagnosis of Amoebic colitis. The patient required a laparotomy and demised. Deep ulcerations with submucosal and intramural tracking of contrast on CT are diagnostic of fulminant amoebic colitis. Although not demonstrated at CT in this case, discontinuous bowel necrosis, omental wrapping (seen at laparotomy in our case) and neovascularisation of the bowel wall may be other features to look out for.

Amebiasis is a frequently occurring parasitic infection in South East Asia. We present a case of a 54-year-old man with right lower quadrant abdominal pain that persisted for longer than 1 year. He had been diagnosed with inflammatory bowel disease in Indonesia. His abdominal pain persisted, despite therapy, and he visited Malaysia for transnational medical advice. Abdominal ultrasound showed fatty liver, gallbladder polyps, and a small left renal stone. Colonoscopy showed multiple ulcers in the cecum and a histopathological examination confirmed amebic infection of the cecum. The colonic ulcers subsided after anti-amebic treatment. This case highlights the need to consider the differential diagnosis of amebic colitis in patients presenting with manifestations of inflammatory bowel disease, especially in patients who live in or have traveled to endemic areas.
