Infections by Aeromonas spp. are a rare cause of systemic infection in normal and immunocompromised hosts. We report the cases of two patients with acute non-lymphoblastic leukemia who developed septic shock by Aeromonas species with unusual soft-tissue complications. One patient who was undergoing consolidation chemotherapy developed septic shock by Aeromonas hydrophila with rhabdomyolysis and subsequent soft-tissue destruction consistent with myonecrosis. She recovered with combination antibiotic therapy and supportive care. The second patient developed neutropenia due to ganciclovir treatment for post-allogeneic transplant cytomegalovirus antigenemia. He developed a rapidly progressive septic shock due to Aeromonas sobria with rhabdomyolysis, multi-organ failure and bilateral lower limb myonecrosis, and died within 48 hours. The portal of entry was not identified in either case. These cases confirm the potentially aggressive nature of these bacteria in neutropenic cancer patients with an unusual tendency to produce muscular and soft-tissue destruction.
气单胞菌属感染在正常宿主和免疫功能低下宿主中是引起全身感染的罕见原因。我们报告了两例急性非淋巴细胞白血病患者的病例,他们因气单胞菌属感染而发生感染性休克,并伴有不寻常的软组织并发症。一名正在接受巩固化疗的患者因嗜水气单胞菌感染发生感染性休克,伴有横纹肌溶解,随后出现与肌肉坏死一致的软组织破坏。她通过联合抗生素治疗和支持治疗得以康复。第二名患者因接受异基因移植后巨细胞病毒抗原血症的更昔洛韦治疗而出现中性粒细胞减少。他因温和气单胞菌感染而迅速进展为感染性休克,伴有横纹肌溶解、多器官功能衰竭和双侧下肢肌肉坏死,并在48小时内死亡。两例病例均未确定感染途径。这些病例证实了这些细菌在中性粒细胞减少的癌症患者中具有潜在的侵袭性,且有产生肌肉和软组织破坏的不寻常倾向。
