Background

Knowing the individual child’s risk is highly useful when deciding on treatment strategies, especially when deciding on invasive procedures. In this study, we aimed to develop a new predictive score for children with bacterial meningitis and compare this with existing predictive scores and individual risk factors.

Methods

We developed the Meningitis Swedish Survival Score (MeningiSSS) based on a previous systematic review of risk factors. From this, we selected risk factors identified in moderate-to-high-quality studies that could be assessed at admission to the hospital. Using data acquired from medical records of 101 children with bacterial meningitis, we tested the overall capabilities of the MeningiSSS compared with four existing predictive scores using a receiver operating characteristic curve (ROC) analysis to assert the area under the curve (AUC). Finally, we tested all predictive scores at their cut-off levels using a Chi-square test. As outcome, we used a small number of predefined outcomes; in-hospital mortality, 30-day mortality, occurrence of neurological disabilities at discharge defined as Pediatric Cerebral Performance Category Scale category two to five, any type of complications occurring during the hospital stay, use of intensive care, and use of invasive procedures to monitor or manage the intracerebral pressure.

Results

For identifying children later undergoing invasive procedures to monitor or manage the intracerebral pressure, the MeningiSSS excelled in the ROC-analysis (AUC = 0.90) and also was the only predictive score able to identify all cases at its cut-off level (25 vs 0%, p < 0.01). For intensive care, the MeningiSSS (AUC = 0.79) and the Simple Luanda Scale (AUC = 0.75) had the best results in the ROC-analysis, whereas others performed less well (AUC ≤ 0.65). Finally, while none of the scores’ results were significantly associated with complications, an elevated score on the MeningiSSS (AUC = 0.70), Niklasson Scale (AUC = 0.72), and the Herson–Todd Scale (AUC = 0.79) was all associated with death.

Conclusions

The MeningiSSS outperformed existing predictive scores at identifying children later having to undergo invasive procedures to monitor or manage the intracerebral pressure in children with bacterial meningitis. Our results need further external validation before use in clinical practice. Thus, the MeningiSSS could potentially be helpful when making difficult decisions concerning intracerebral pressure management.

AIM

Vaccine‐preventable pathogens causing severe childhood infections include Haemophilus influenzae type b (Hib), Streptococcus pneumoniae and Neisseria meningitidis. In this study conducted in a Swedish Arctic region, we evaluated the effects of general infant Hib and pneumococcal vaccination on invasive infectious diseases among children and assessed the need of meningococcal vaccination.

METHODS

We identified cases of bacterial meningitis and sepsis from diagnosis and laboratory registers in the Västerbotten Region, Sweden, during 1986–2015. We then reviewed medical records to confirm the diagnosis and extract data for assessing incidence changes, using an exploratory data analysis and a time‐series analysis.

RESULTS

Invasive Haemophilus disease declined by 89.1% (p < 0.01), Haemophilus meningitis by 95.3% (p < 0.01) and all‐cause bacterial meningitis by 82.3% (p < 0.01) in children aged 0 to four years following general infant Hib vaccination. Following pneumococcal vaccination, invasive pneumococcal disease declined by 84.7% (p < 0.01), pneumococcal meningitis by 67.5% (p = 0.16) and all‐cause bacterial meningitis by 48.0% (p = 0.23). Incidence of invasive meningococcal disease remained low during the study period.

CONCLUSION

Remarkable sustained long‐term declines of invasive infectious diseases in younger children occurred following infant Hib and pneumococcal vaccinations in this Swedish Arctic region. Despite not offering general infant meningococcal vaccination, incidence of invasive meningococcal disease remained low.

AIM: Streptococcus pneumoniae commonly causes respiratory tract infections including acute otitis media and pneumonia. In this study, we evaluated the impact of general infant pneumococcal vaccination, introduced in Sweden in 2009, on respiratory tract infections.

METHODS: We studied the incidence of respiratory tract infections and antibiotic consumption in Västerbotten County, Sweden, during 2005-2014 using the County Council's diagnosis register.

RESULTS: Comparing the prevaccination period of 2005-2008 to 2014, the incidences of all-cause acute otitis media decreased significantly in children aged 0-4 and five years to 17 years, by 41.5% and 20.9%, respectively. In addition, we also noted significant reductions in sinusitis and other upper respiratory tract infections, and some reductions in adults. Antibiotic consumption for upper respiratory tract infections decreased by 37.1%, with the largest decrease occurring in children aged 0-4 years. For pneumonia, the incidence significantly decreased by 28.6% for children aged 0-4 years, with no significant changes in older children or adults.

CONCLUSION: Pneumococcal vaccination was followed by reduced incidence of upper respiratory tract infections and antibiotic consumption in vaccinated children, with some indications of possible herd immunity. For pneumonia, a major reduction was noted limited to the youngest children.

AIM: This Swedish study reviewed differences in clinical presentation and laboratory findings of acute bacterial meningitis in children aged one month to 17 years in Vasterbotten County, Sweden. METHODS: A register-based study was performed for the period 1986 to 2013 using the Vasterbotten County Council's patient registration and laboratory records at the Department of Laboratory Medicine at Umea University Hospital. The medical records were reviewed to extract data and confirm the diagnosis. RESULTS: We found 103 cases of acute bacterial meningitis, and Haemophilus influenzae was the most common pathogen, causing 40.8% of all cases, followed by Streptococcus pneumoniae at 30.1% and Neisseria meningitidis at 9.7%. Significant differences in clinical presentation and laboratory findings were found. Younger children were more unwell than older ones and had more diffuse symptoms on admission. In addition, important sex-related differences were found that might explain the higher case fatality rates for boys than girls. For example, boys tended to have a higher disturbance in the blood-brain barrier, which is known to be a negative prognostic factor. CONCLUSION: This study showed that clinical presentation for acute bacterial meningitis varied with age and sex and, to a lesser extent, on the duration of the illness.
