Escherichia coli Meningitis in a Patient With Urinary Tract Infection: A Case Report

This article discusses a case of Escherichia coli (E. coli) meningitis resulting in altered mental status in a patient with multiple pre-existing comorbidities. The case highlights the underestimated risk of community-acquired gram-negative meningitis in adults, which can have a high mortality rate, particularly in elderly patients with sepsis and urinary tract infections. Diagnosis of E. coli meningitis was confirmed by analyzing cerebrospinal fluid obtained through the lumbar puncture and blood cultures. Treatment involved prompt administration of antibiotics and supportive care. However, the emergence of antibiotic resistance, such as extended-spectrum beta-lactamase production, in community-acquired E. coli meningitis is an increasing concern. Therefore, early recognition and appropriate management are crucial in the diagnosis and treatment of this life-threatening condition.
