is an anaerobic bacterium that causes rapidly progressive myonecrosis, bacteremia, and central nervous system infection. It has been reported as a complication of hemolytic uremic syndrome (HUS) in 8 children worldwide; 5 children died, and the 3 reported survivors had surgically treated disease. We present 3 cases of complicating HUS in children, including the first 2 reported cases of survival without surgical intervention. All patients presented with classic cases of HUS with initial clinical improvement followed by deterioration. Patient 1 had rising fever, tachycardia, and severe abdominal pain 24 hours after admission. She developed large multifocal intraparenchymal cerebral hemorrhages and died 12 hours later. Autopsy revealed intestinal necrosis, myonecrosis, and encephalitis. Patient 2 had new fever, increasing leukocytosis, and severe abdominal pain on hospital day 4. She was diagnosed with bacteremia and treated with metronidazole, meropenem, and clindamycin. Patient 3 had new fever and increasing leukocytosis on hospital day 3; blood cultures grew , and she was treated with penicillin. Patients 2 and 3 improved rapidly and did not require surgery. is a potential co-infection with It thrives in the anaerobic environment of -damaged intestinal mucosa and translocates to cause systemic infection. Fever, tachycardia, a rising white blood cell count, and abdominal pain out of proportion to examination are key findings for which physicians should be vigilant. Timely evaluation by anaerobic blood culture and early initiation of antibiotics are necessary to prevent fatalities.
是一种厌氧细菌,可导致快速进展的肌坏死、菌血症和中枢神经系统感染。据报道,它是全球8名儿童溶血尿毒综合征(HUS)的并发症;5名儿童死亡,3名报告的幸存者接受了手术治疗。我们报告3例儿童并发HUS的病例,包括首例报告的2例未经手术干预存活的病例。所有患者均表现为典型的HUS病例,最初临床症状改善,随后病情恶化。患者1入院24小时后出现发热、心动过速和严重腹痛。她出现大量多灶性脑实质内出血,12小时后死亡。尸检显示肠道坏死、肌坏死和脑炎。患者2在住院第4天出现新的发热、白细胞增多和严重腹痛。她被诊断为菌血症,接受甲硝唑、美罗培南和克林霉素治疗。患者3在住院第3天出现新的发热和白细胞增多;血培养生长出 ,她接受青霉素治疗。患者2和3迅速康复,无需手术。 是一种潜在的合并感染,它在受损肠黏膜的厌氧环境中繁殖并易位导致全身感染。发热、心动过速、白细胞计数升高以及与检查结果不成比例的腹痛是医生应警惕的关键表现。通过厌氧血培养进行及时评估并早期使用抗生素对于预防死亡是必要的。
