溃疡性结肠炎主要结合患者临床表现、内镜表现以及病理组织学特点进行综合诊断,是一种排除性诊断,但误诊率仍高,主要与各种急性感染性肠炎、单纯阿米巴肠病、克罗恩病等肠道炎性疾病进行鉴别。溃疡性结肠炎合并阿米巴感染的诊断通常在诊断为溃疡性结肠炎后,筛查阿米巴感染情况。筛查阿米巴感染方法有病理组织学检查、粪便相关检查(包括粪便镜检、粪便培养、粪便中检测阿米巴抗原)、血清学检查以及PCR诊断技术等;粪便镜检是溃疡性结肠炎患者最为广泛使用的筛查阿米巴感染方法,但其灵敏度及特异度均较低。阿米巴感染最常见的治疗药物为甲硝唑、替硝唑等硝基咪唑类药物,治愈率可达到90%以上;帕罗霉素等肠腔内药物治疗阿米巴疗效差;其他治疗方法包括5-氨基水杨酸制剂、激素、免疫抑制剂和(或)生物制剂等药物,容易导致机会感染。 相似文献

Two cases of amebic colitis that resulted in perforation of the colon, an ominous complication, are presented. The first was diagnosed preoperatively as acute ulcerative colitis with toxic megacolon, and the second as peritonitis complicating acute cholecystitis. In both instances the correct diagnosis was made after operation. The first patient recovered after colectomy and antiamebic therapy, but the second patient died in the early postoperative period, in septic shock. Amebic colitis occurs infrequently in the United States, and the diagnosis is rarely considered. In most cases an initial diagnosis of ulcerative or granulomatous colitis is made and the true diagnosis is recognized only after operation for colonic perforation or hepatic abscess. It is suggested that amebic colitis should be considered more frequently in cases of patients who have diarrhea. Stool examination for ova and parasites is often negative in amebic colitis. The IHA is usually positive in emebiasis, and should be performed early in casesof patients who have bloody diarrhea or other clinical symptons when amebiasis is suspected. Rectal biopsy is also a useful diagnostic approach, but failed to reveal amebae in one of our cases. Finally, it is suggested that operation be performed urgently when fulminating amebic colitis is not reversed by antiamebic therapy, when peritonitis occurs even with antiamebic treatment in progess, and for colonic perforation or toxic megacolon even when antiamebic therapy has not been indicated. 相似文献

Summary and Conclusions Seven patients with perianal skin amebiasis are discussed; six were men and one was a woman. The ages varied from 28 to 48
years. Grossly, lesions vary from a single ulcer to a massive, fungous, ulcerative lesion; often it may be confused with a
simple anal ulcer, lymphogranuloma venereum, condyloma, cancer and other benign anal lesions. Biopsy or scraps of the lesion
revealE. histolytica in its trophozoite form.
A combination of emetine and other amebicides is the treatment of choice. If untreated, the lesion will grow rapidly and may
kill the patient. This happened to one of my patients. In all my cases, the skin infection was due to a previous amebic colitis.
Incomplete treatment for amebiasis of the colon may lead to a perianal skin amebiasis. Constipation may be the only symptom.
Perianal skin amebiasis is a rare complication of amebic colitis.

Previous reports indicate that metronidazole is highly effective in the therapy of colonic amebiasis and in the treatment of hepatic amebic abscesses when combined with aspiration. A retrospective review of 15 cases of intestinal amebiasis and 12 patients with amebic liver abscesses treated with metronidazole alone is reported. Based on the literature and the clinical response of the patients reported herein, metronidazole is the initial drug of choice in the therapy of amebic colitis because of its ease of administration, efficacy, and low toxicity. In the treatment of hepatic amebic abscesses, metronidazole alone is adequate therapy for most cases, but occasionally there will be progression of the disease despite standard dosages of the drug. 相似文献

Amebic colitis can mimick Crohn's disease of the colon and ulcerative colitis. Inflammatory bowel disease (IBD) patients can also be carriers of amebae. Since steroids can provoke amebic activity and even cause a fulminating colitis, it is necessary to determine that amebae do or do not exist. Furthermore, amebae can be easily eliminated by drug therapy but it is hard to eradicate IBD. Despite the above, diagnostic modalities for IBD are as effective as those for amebiasis, particularly for Crohn's disease with ileal involvement. Problems in differential diagnosis arise with IBD grossly limited to the colon. In these cases, false negative stool studies are increased by diarrhea and preparation for examinations, and both stool studies and serologies are compromised by steroids. If the clinical course of IBD is downhill, the clinician is justified in starting steroids even if evaluation for amebiasis incomplete. If, however, the index of suspicion is high, concomitant treatment with Metronidazole would be reasonable. 相似文献

Abstract: In this study we report on two cases of amebic colitis treated in our hospital. On admission both patients were in a severe state of malnutrition due to intermittent diarrhea which had continued for one month. Both patients suffered from amebic colitis presumably transmitted by homosexual intercourse. A definite diagnosis of amebic colitis was made from both fecal examination and colonoscopic biopsy. After the diagnosis was made, the patients were treated with metronidazole. This medication can eliminate Entamoeba histolytica, although it was insufficient for the treatment of the patients’malnutrition. Therefore we used total parenteral nutrition to treat their malnutrition. It was successful and resulted in their recovery and discharge. These two cases indicate that total parenteral nutrition therapy is useful for supporting the recovery of patients with amebiasis. 相似文献

OBJECTIVE: To determine whether the frequency or severity of invasive amebiasis is increased in patients with AIDS. DESIGN: A case-control sampling approach, based on an autopsy registry. SETTING: General Hospital of Mexico City, Mexico, a large government-supported, tertiary care medical institution. PATIENTS, PARTICIPANTS: Ninety-four patients with AIDS and 335 historical and contemporary, age- and sex-matched controls who were defined as dying, but not because of AIDS. RESULTS: The odds ratio (OR) for mortality from invasive amebiasis was the same for cases and controls (0.7; 95% confidence interval, 0.07-7.2). By contrast, the OR for other diseases, such as miliary tuberculosis, cytomegalovirus infection, Pneumocystis carinii pneumonia and toxoplasmosis was greatly increased. Only one patient with AIDS had amebiasis of the common amebic ulcerative colitis type, without extraintestinal involvement. CONCLUSION: In conclusion, we show that the frequency and severity of invasive amebiasis is not increased in Mexican patients with AIDS. 相似文献

BACKGROUND/AIMS: Sweet's syndrome (SS) is a severe dermatosis that may be an extraintestinal manifestation of inflammatory bowel disease (IBD). Worldwide, 35 cases of SS associated with IBD have been reported. We present the first case of severe, recurrent SS in combination with amebic infection and ulcerative colitis complicated with multiple other extraintestinal manifestations. METHODS: Disease course was monitored by serum YKL-40 and C-reactive protein (CRP), white blood cell count, albumin and the Simple Clinical Colitis Activity Index (SSCAI). The amebic infection was diagnosed by direct microscopy of wet mount scrapings sampled by repetitive sigmoidoscopies. RESULTS: The patient was diagnosed with left-sided ulcerative colitis and SS combined with extraintestinal manifestations: arthropathies, iridocyclitis and erythema nodosum. Cysts of Entamoeba histolytica were detected in the stools in two separate periods of time. Serum YKL-40 increased prior to CRP and correlated with disease activity, SCCAI, CRP, white blood cell count and inversely with serum albumin. CONCLUSION: This case gives further support for SS being an extraintestinal manifestation of ulcerative colitis. YKL-40 may be useful in monitoring the disease course of IBD. 相似文献

We investigated the prevalence of amebiasis in patients with ulcerative colitis residing in two geographical regions with
different socioeconomic status and climatic conditions, and its effect on the age of onset, duration, localization, and activity
of disease. Ninety patients from a high socioeconomic location (group I) and 28 cases from a low socioeconomic location (group
II) were enrolled. Median age at disease onset was significantly higher in group I compared with in group II. Prevalence of
amebiasis in group I was significantly lower than in group II. A considerably number of patients with amebiasis in group I
had a history of travel to the cities with a lower socioeconomic level, mainly located in the east of Turkey. There was a
strong relationship between presence of amebiasis and history of travel to eastern parts of Turkey among residents from the
northwestern part of Turkey. Median age and age at time of diagnosis were significantly lower in patients with amebiasis compared
with those without infection. In patients with mild disease activity, prevalence of amebiasis was significantly lower compared
with those with moderate or severe disease activity. In conclusion, prevalence of amebiasis was markedly higher in the southeast
compared to the northwest of Turkey. Travel to regions with low socioeconomic status may be considered a risk factor for amebiasis
in patients with ulcerative colitis. Amebiasis enhances disease activity in ulcerative colitis. 相似文献
