NEONATAL MENINGITIS AND INTRACRANIAL EMPYEMA DUE TO PROTEUS MIRABILIS: A CASE REPORT

Apresentação do caso

Term Newborn, male, small for gestational age, borned by cesarean delivery because of acute fetal distress and gastroschisis, was submitted to surgery immediately after birth on 01/14/23. On 01/27/23 the newborn was presented with hyperthermia and apnea, resulting in investigation for sepsis. Blood and liquor cultures were positive for Proteus mirabilis and sensitive to fourth generation cephalosporins. The baby was submitted to transfontanellar ultrasound, that showed signs of supratentorial ependymitis with ventriculomegaly on 02/02/23, causing the neonatologists to change the therapy for carbapenem and aminoglycoside. The patient, however, evolved with seizures, hyperthermia and apnea. On 03/03/23 was submitted to magnetic resonance imaging that showed empyemas in the middle and posterior cranial fossa. Medical assistant decided to continue the antimicrobial therapy and to not submit the baby to a surgery intervention. The baby evolved with negative cultures and with improvement of symptoms, with hospital discharge on 04/12/23 (3 months old).

Discussão

Neonatal bacterial meningitis is a devastating infection, associated with many neurological complications, such as seizures, encephalopathy and intracranial empyema. The most common pathogens are Group B Streptococcus (GBS) and Escherichia coli, but the Proteus mirabilis is considered a pathogen with great morbidity and mortality. Proteus mirabilis is a Gram-negative bacteria, more commonly associated with urinary Tract infections, that corresponds to 4% of meningitis cases and it is associated with cerebral empyemas and complications.

Comentários finais

Neonatal meningitis due to Proteus mirabilis is a potential life threatening condition. This case report is relevant considering the presentation, the unusual pathogen and the outcomes. Patients with these findings should remain in follow-up considering the potential complications post acute phase of the infection.
