Abstract
Background: Intraventricular antimicrobial therapy (IVT), defined as the direct installation of antimicrobial agents into the lateral ventricles has been utilized as the last therapeutic option for the treatment of multidrug-resistant ventriculitis. The aim of this case series is to report our institution’s experience with IVT in pediatric patients with ventriculitis.
Material and Methods: Retrospective chart review was done. The demographic data, cerebrospinal fluid (CSF) culture isolates, treatment regimens, and clinical outcomes of these patients were collected and described.
Results: Between 2016 to 2018, seven (7) pediatric patients diagnosed with ventriculitis caused by multidrug-resistant organisms underwent intraventricular antimicrobial therapy in combination with intravenous therapy. The median age was 1 year (range 1 month to 17 years old, mean: 4.4 years). Fifty-seven (57) percent of the patients were females. The isolated pathogens were Acinetobacter baumannii MDRO (n = 3), Klebsiella pneumoniae MDRO (n = 2), Methicillin-resistant Staphylococcus aureus (n = 1), and Methicillin-resistant Staphylococcus epidermidis (n = 2).One patient had mixed isolates on CSF culture (Acinetobacter baumannii and MRSE). The antimicrobial agents for IVT used were colistin (n = 4), vancomycin (n = 2), and gentamicin (n = 1). The mean time to initiation of intraventricular therapy from the diagnosis of ventriculitis was 19 days. The mean duration of IVT therapy was 15 days. The survival rate was 57%.
Conclusion: Ventriculitis caused by drug-resistant organisms is an emerging concern. Optimal therapy is not yet established and experience with IVT is limited. This series showed that there were no adverse effects related to IVT thus it may be considered an option for MDRO ventriculitis. Gram negative organisms are more common causes of ventriculitis in our institution.
