Fatal Elizabethkingia anophelis Bacteremia Complicated by Meningitis in a Hemodialysis Patient: A Case Report and Review of the Literature
Abstract
Elizabethkingia anophelis (E. anophelis) is an emerging multidrug-resistant pathogen in hospital aquatic environments associated with severe infections. Reports of E. anophelis infection in hemodialysis patients are rare, and meningitis caused by this organism has been poorly characterized. We report a fatal case of meningitis in a hemodialysis patient caused by E. anophelis bacteremia and review previous cases of E. anophelis infection in hemodialysis patients. A 68-year-old man with end-stage renal disease due to diabetic kidney disease on maintenance hemodialysis was admitted with fever after recent glucocorticoid therapy. Blood cultures grew E. anophelis. Despite initial antimicrobial treatment, the patient developed bacterial meningitis with impaired consciousness and abnormal cerebrospinal fluid (CSF) findings. Although CSF cultures were negative, repeated blood cultures remained positive for E. anophelis, and alternative pathogens were excluded using a multiplex meningitis/encephalitis panel. Therefore, meningitis due to E. anophelis was considered. Antimicrobial therapy was changed to levofloxacin (LVFX) plus sulfamethoxazole-trimethoprim according to susceptibility testing and CSF penetration, resulting in improvement of inflammatory markers, CSF findings, and consciousness. However, the patient subsequently developed nonocclusive mesenteric ischemia (NOMI) and massive iliopsoas hematomas and died of hemorrhagic shock. Autopsy confirmed NOMI without bowel…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
