RESUMEN
OBJECTIVES: The aims of the study were to analyze the demographics, presentation, laboratory findings, and complications of pediatric Streptococcus pneumoniae meningitis since the introduction of the 13-valent pneumococcal conjugate vaccine, to improve recognition, and to minimize patient morbidity and mortality. METHODS: This study used a retrospective analysis of pediatric pneumococcal meningitis cases at 2 tertiary healthcare systems in the Southeastern United States from 2010 to 2018. RESULTS: We describe 21 cases of pneumococcal meningitis. All patients presented with fever, 95% had altered mental status by history or examination, and 48% had meningeal signs. Forty-three percent had seen another provider within 48 hours of admission. Forty-eight percent had delay in lumbar puncture (LP) of more than 6 hours after antibiotic administration, decreasing rates of positive cerebrospinal fluid cultures from 100% to 40% (P < 0.001). Decision to delay LP was due to either low suspicion for meningitis (n = 4) or clinical instability (n = 6) and was associated with lower rates of meningeal signs (P = 0.014) and higher rates of altered mental status on examination (P = 0.031). Fourteen patients (67%) were up-to-date on pneumococcal immunization. Serotypes were determined in 16 cases, with 2 patients (13%) immunized against the strain that infected them. Primary outcomes included seizures (48%), hearing loss (48%), cranial nerve palsy (33%), and death (5%). Delay in LP with low suspicion for meningitis was associated with longer hospital length of stay approaching statistical significance (P = 0.053). CONCLUSIONS: Pneumococcal meningitis remains a relevant and potentially fatal disease despite widespread use of 13-valent pneumococcal conjugate vaccine. Its diagnosis is often delayed during interactions with physicians, which may put patients at increased risk for poor clinical outcomes.

BACKGROUND: Data on oral vancomycin for primary sclerosing cholangitis (PSC)-associated inflammatory bowel disease (IBD) are limited. AIMS: Using data from the Paediatric PSC Consortium, to examine the effect of vancomycin on IBD activity. METHODS: In this retrospective multi-centre cohort study, we matched vancomycin-treated and untreated patients (1:3) based on IBD duration at the time of primary outcome assessment. The primary outcome was Physician Global Assessment (PGA) of IBD clinical activity after 1 year (±6 months) of vancomycin. We used generalised estimating equations (GEE) to examine the association between vancomycin and PGA remission, adjusting for IBD type, severity and medication exposures. Secondary outcomes included serum labs and endoscopic remission (global rating of no activity) among those with available data and also analysed with GEE. RESULTS: 113 PSC-IBD patients received vancomycin (median age 12.7 years, 63% male). The matched cohort included 70 vancomycin-treated and 210 untreated patients. Vancomycin was associated with greater odds of IBD clinical remission (odds ratio [OR] 3.52, 95% CI 1.97-6.31; adjusted OR [aOR] 5.24, 95% CI 2.68-10.22). Benefit was maintained in sensitivity analyses restricted to non-transplanted patients and those with baseline moderate-severe PGA. Vancomycin was associated with increased odds of endoscopic remission (aOR 2.76, 95% CI 1.002-7.62; N = 101 with data), and with lower CRP (p = 0.03) and higher haemoglobin and albumin (both p < 0.01). CONCLUSION: Vancomycin was associated with greater odds of IBD clinical and endoscopic remission. Additional, preferably randomised, controlled studies are needed to characterise efficacy using objective markers of mucosal inflammation, and to examine safety and define optimal dosing.
