A patient with a fulminant amebic colitis coexisting with intestinal tuberculosis had a sudden onset of crampy abdominal pain, mucoid diarrhea, anorexia, fever and vomiting with signs of positive peritoneal irritation. Fulminant amebic colitis occurring together with intestinal tuberculosis is an uncommon event and may present an interesting patho-etiological relationship. The diagnosis was proven by histopathologic examination of resected specimen. Subtotal colectomy including segmental resection of ileum, about 80 cm in length, followed by exteriorization of both ends, was performed in an emergency basis. Despite all measures, the patient died on the sixth postoperative day. The exact relationship of fulminant amebic colitis and intestinal tuberculosis is speculative but the possibility of a cause and effect relationship exists. Fulminant amebic colitis may readily be confused with other types of inflammatory bowel disease, such as idiopathic ulcerative colitis, Crohn's disease, perforated diverticulitis and appendicitis with perforation. This report draws attention to the resurgence of tuberculosis and amebiasis in Korea, and the need for the high degree of caution required to detect it.

A patient with amebic colitis in which the rare complication of ameboma developed accompanying liver abscess is presented. The diagnosis was made by colonic mucosal biopsy and microscopic stool examination which revealed hematophagous trophzoites of Entamoeba histolytica. All rnanifestations of this patient's illness, including liver abscess, completley reverted to normal after appropriate therapy.

An acute fulminant amoebic colits rarely develops as a complication of amoebiasis, and is difficult to diagnose and treat when it occurs. It is a life-threatening disease, and associated with a very high mortality rate. Herein, a case 42-old-year man, who had a generalized peritonitis caused by an acute fulminant amoebic colitis, is reported, with a review of the literature. He died of multiple organ failure, following sepsis and disseminated intravascular coagulation, on the 19th day after his operation, despite treatment with aggressive surgery and anti-amoebic agents. An emergency laparotomy should be considered when an acute fulminant amoebic colitis deteriorates despite the use of intensive anti-amoebic therapy, especially when there is an acute episode suggestive of perforation. A primary total resection of the diseased colon is one of the treatments of choice.

The hemolytic uremic syndrome(HUS), a heterogenous group of disorders characterized by micorangiopathic hemolytic anemia, thrombocytopenia, and azotemia, is the most frequent cause of acute renal failure in children. The association of the HUS with E. coli O157:H7 has been well-described, but the other intestinal infection have been relatively less reported to date. We report a 18-month-old boy presenting with typical clinical characteristics of HUS associated with amoebic dysentery with a brief review of literatures.

BACKGROUND/AIMS: Ulcerative colitis is an inflammatory bowel disease with unknown etiology, which has waxed and waned course. It is diagnosed by colon study, pathology, and especially colonoscopy. It is difficult to differentiate between ulcerative colitis and other infectious colitis, especially amebic colitis, and to confirm of remnant lesion by endoscopic findings. METHODS: Magnifying colonoscopy has 100 time magnifying power compared to 30 time of conventional colonoscopy. By spraying 0.2% indigo carmine dye, we evaluated the magnifying and microscopic findings of 31 colonic mucosa of 23 patients with ulcerative colitis. RESULTS: Initial and magnifying chromoscopic findings in ulcerative colitis were loss of cryptal opening 72% (13/18), loss of submucosal vessel 89% (16/18), mucosal denudation (or microscopic erosion) 83% (15/18), and mucosal unevenness 94% (17/18). Recovery rate of magnifying chromoscopic findings after treatment in ulcerative colitis were in crytal opening 80% (8/10), submucosal vascularity 60% (6/10), mucosal denudation (microscopic erosion) 30% (3/10), and in mucosal unevenness 40% (4/10). CONCLUSIONS: It is suggested that magnifying chromoscopic findings in ulcerative colitis may be useful in initial diagnosis and confirmation of remnant lesion, but, not in prediction of clinical severity.

Intestinal amoebiasis is caused by the protozoan Entamoeba histolytica. Amoebic colitis is usually acquired by ingesting contaminated food or water, but it can be associated with cell-mediated immunosuppression in organ-transplant recipients. We present a case of invasive amoebic colitis in a kidney-transplant recipient who was treated successfully with metronidazole and adjusted immunosuppressive therapy. The patient was a 49-year-old man who had undergone renal transplantation 15 years earlier. He complained of diarrhea accompanied by mild lower abdominal pain over five weeks, and the diagnosis of amoebic colitis was made with a colonoscopic biopsy. The colonoscopic findings showed multiple, round, scattered ulcerations throughout the colon, and trophozoites of E. histolytica were identified in the base of these ulcers. We treated his colitis with metronidazole and a reduction in immunosuppressive therapy.

Nowadays, inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, is increasing; however, infectious colitis, such as amebic colitis, is decreasing, so many doctors are not apt to be interested in infectious colitis. In addition, recently amebic colitis has been relatively rare in Korea, and the colonoscopic and the pathologic findings of amebic colitis are very similar to those of other inflammatory bowel diseases. As a consequence, the diagnosis is very difficult if the cyst or the trophozoite of the ameba is not found in the stool examination or in the tissue pathology. The authors experienced three cases in which initial diagnoses of tuberculous colitis, ulcerative colitis, and a simple ulcer were made based on colonoscopic and X-ray findings. However a colonoscopic biopsy revealed a trophozoite form of ameba in the tissue. Hence, a diagnosis of amebic colitis could be made with confidence. Based on these results, we insist that infectious colitis should be included in the differential diagnosis when making a diagnosis of inflammatory bowel disease. In addition, it is extremely important to consider all kinds of infectious colitis, such as amebic colitis.

Some cases have reported that amebic colitis leads to serious complications that are caused by a misdiagnosis of an inflammatory bowel disease and consequential ill-managed steroid therapy. Therefore, it should be stressed that the differential diagnosis on such a case is very important. Eosinophilic colitis may reveal its presence as diarrhea, abdominal pain, ascites, and eosinophilic deposits in tissues. Therefore, it is highly necessary to make a differential diagnosis to distinguish eosinophilic colitis from other infectious or inflammatory bowel diseases. We report a case of amebic colitis, which was mistakenly diagnosed as eosinophilic colitis and a liver eosinophilic abscess in a young male who complained of bloody diarrhea and right upper quadrant pain. However, the misdiagnosed steroid therapy did not aggravate the progress of the amebic infection.
