Clinical characteristics and prognostic factors in childhood bacterial meningitis: a multicenter study

Hemophilus Septicemia Meningitis in an 11-Month-Old Vaccinated Infant

Haemophilus influenzae is a gram-negative pleomorphic coccobacillus associated with many diseases, such as meningitis, pneumonia, septicemia, cellulitis, and otitis media. The most virulent and most common serotype is H. influenzae type b (Hib), which was responsible for the majority of meningitis cases until the development of vaccines that led to a decrease in its incidence worldwide. Here, we report the case of an 11-month-old female infant who was previously healthy and fully vaccinated against Hib and developed sepsis and meningitis. The patient was managed as a case of partially treated bacterial meningitis but failed to respond to a short-duration course of antibiotics and had focal seizures of the left hand. Non-contrast brain MRI revealed multiple and bilateral brain abscesses more evident on the left side. The patient was then followed up with imaging every 10-14 days to monitor the response and resolution of the brain abscesses. She was successfully treated with a full course of intravenous ceftriaxone for six weeks until imaging was clear and the brain abscesses were nearly undetected. Invasive H. influenzae infections are considered emerging cases, and there is a need to consider and suspect the disease even in fully vaccinated patients.

Treatment Outcomes and Associated Factors among Children Hospitalized with Acute Bacterial Meningitis in Eastern Ethiopia: A Cross-Sectional Study

Background

Bacterial meningitis is a common central nervous system infection that is associated with high morbidity and mortality in pediatrics. In Ethiopia, little is known about treatment outcomes of acute bacterial meningitis and associated factors among hospitalized children.

Objective

To assess treatment outcomes of acute bacterial meningitis and associated factors among hospitalized children with acute bacterial meningitis in the Hiwot Fana Specialized University Hospital pediatric ward.

Methods

A retrospective cross-sectional study was conducted at the pediatric ward of Hiwot Fana Specialized University Hospital, eastern Ethiopia. Relevant data were collected using a structured data-collection tool from patients' medical charts. Bivariate and multivariate logistic regression analyses were done to identify predictors of treatment outcomes. OR with 95% CI and P≤0.05 was used for statistical significance.

Results

A total of 200 children with acute bacterial meningitis were included in the study, of which 92% were aged ≥2 months and the majority (128, 64%) had delayed (≥72 hours) presentation to the hospital. At admission, 181 (90.5%) were febrile, 92 (46%) had depressed level of consciousness, and 40 (20%) had had seizures. Most (126, 63%) had documented medical comorbidities. The antibiotic combination of ampicillin and gentamycin had been frequently administered in children aged <2 months while ceftriaxone was commonly prescribed for those aged >2 months. Of the total study participants, 154 (77%) showed successful treatment outcomes, while 46 (23%) experienced poor treatment outcomes (died or "self"-discharged). Level of consciousness (AOR 3.25, 95% CI 1.21-8.75), duration of illness before admission (AOR 3.74, 95% CI 1.76-7.98), and antibiotic-regimen change (AOR 4.7, 95% CI 2.4-10) were predictors of treatment outcomes.

Conclusion

The majority of study participants experienced good treatment outcomes. Unconsciousness, antibiotic-regimen change, and duration of illness before hospitalization were significantly associated with treatment outcomes. Early treatment, linkage of primary-health facilities to tertiary health-care centers, and availability of diagnostics should be promoted to improve patient outcomes.

If You Build It, They Will Come: Initial Experience with a Multi-Disciplinary Pediatric Neurocritical Care Follow-Up Clinic

Pediatric Neurocritical Care diagnoses account for a large proportion of intensive care admissions. Critical care survivors suffer high rates of long-term morbidity, including physical disability, cognitive impairment, and psychosocial dysfunction. To address these morbidities in Pediatric Neurocritical Care survivors, collaboration between Pediatric Neurology and Pediatric Critical Care created a multidisciplinary follow-up clinic providing specialized evaluations after discharge. Clinic referrals apply to all Pediatric Neurocritical Care patients regardless of admission severity of illness. Here, we report an initial case series, which revealed a population that is heterogenous in age, ranging from 1 month to 18 years, and in diagnoses. Traumatic brain injuries of varying severity as well as neuroinfectious and inflammatory diseases accounted for the majority of referrals. Most patients (87%) seen in the clinic had morbidities identified, requiring ongoing evaluation and expansion of the clinic. Cognitive and psychological disturbance were seen in over half of patients at the initial clinic follow-up. Sleep disturbances, daytime fatigue, headache or chronic pain, and vision or hearing concerns were also common at initial follow-up. Data from this initial population of clinic patients reiterates the need for specialized follow-up care, but also highlights the difficulties related to providing this comprehensive care and evaluating interventions to improve outcomes.

Microbiological Features of Upper Respiratory Tract Infections in Bulgarian Children for the Period 1998-2014

BACKGROUND

Across the globe, upper respiratory tract infections (URTIs) are the most prevalent cause of morbidity in childhood.

AIMS

The aim of our study is to analyze the incidence and etiology of bacterial URTIs in Bulgarian children, as well as the increasing antimicrobial resistance to the most common etiologic agents over a period of 17 years.

STUDY DESIGN

Retrospective study.

METHODS

The study material comprised the data from 4768 patients (aged 1-16 years) with URTI during the period from 1998-2014. Specific microbiology agent detection was performed by culture examination. Susceptibilities to the investigated pathogens were determined by the disk diffusion method and minimal inhibitory concentration according to the criteria of the Clinical and Laboratory Standards Institute (CLSI). Polymerase chain reaction was used to detect the presence of β-lactam resistance genes.

RESULTS

We identified the following as the most common URTI bacterial pathogens: Streptococcus pneumoniae (40.94%), Streptococcus pyogenes (34.16%), Haemophilus influenzae (44.23%), Moraxella catarrhalis (39.19%) and Staphylococcus aureus (23.88%). In more than 70% of cases, a polymicrobial etiology was found. The most commonly affected individuals were pre-school-aged children, which accounted for more than 36% of all patients. During the study period, a dramatic increase in resistance to antibiotic agents was observed. The most frequent types of resistance were the enzymatic inactivation of penicillins and cephalosporins (close to 100% in staphylococci and moraxellae) and inducible macrolide-lincozamide resistance (about 20% of Gram-positive cocci).

CONCLUSION

Due to mandatory immunization against pneumococci and H. influenzae in Bulgaria and the vast expanding resistance to the most popular antimicrobial agents changes in the etiology of URTI have recently been noted. Regular analysis of this etiological dynamic and the antimicrobial resistance of respiratory pathogens is important for choosing the correct therapy and successful treatment.
