Abstract
PURPOSE: In infections of the Central Nervous System (iCNS), rapid identification of causing pathogens is crucial for survival and to avoid long-term sequelae. Targeted therapy may reduce side effects and development of antibiotic resistance. New molecular-based syndromic tests such as the "meningitis/encephalitis panel" (MEP) allow accelerated pathogen identification from cerebrospinal fluid. We conducted a clinical study to evaluate the MEP's efficacy in paediatric patients. METHODS: Cohort study in a unique clinical setting by comparing the outcome data of two neighbouring Children's Hospitals in Germany which are comparable in size, catchment area and equipment but differ regarding availability of the MEP: study centre 1 (SC1): yes; SC2: no. The study population included 213 paediatric patients with a suspected iCNS (SC1: 106; SC2: 107), with comparable age, CRP at admission and frequency of intensive care. The primary outcome was total use of antibiotics. RESULTS: Total antibiotic use per patient was numerically lower in SC1 than in SC2 (SC1: median 2.83 days; SC2 3.67 days; p = 0.671). Multiple linear regression analysis did not show a relevant association between MEP-availability and total antibiotic use (ß = 0.1, 95% confidence interval [-1.46; +1.67], p = 0.897). In the subcohort with suspected meningoencephalitis (SC1: 18, SC2: 17), duration of acyclovir treatment was shorter in SC1 than in SC2 (median 1.3 days vs. 2.7 days, descriptive p = 0.0397). CONCLUSIONS: The add-on use of the MEP in paediatric patients with suspected iCNS was associated with a non-significant reduction in total antibiotic use, and with a reduced exposure to acyclovir in treated patients.
