Background And Purpose:
Neisseria meningitidis usually causes severe infection in children, but occurs only sporadically in Taiwan. However, the number of infections increased in 2001 and 2002. This study was performed to ascertain the epidemiology and clinical manifestations of infections caused by meningococcus in a pediatric population.
Methods:
The medical charts of patients with meningococcal diseases who were admitted to Chang Gung Children's Hospital, Taoyuan, Taiwan, from July 1998 to December 2005 were retrospectively reviewed. Data were analyzed for age distribution, serogroups, clinical diagnoses, treatment, acute complications, and outcomes.
Results:
Sixteen children with meningococcal disease were identified. Their ages ranged from 1 month to 15 years (average, 3 years). Most patients (62.5%) were younger than 1 year and the second most frequent age group was 6 to 15 years (18.75%). There were 56.25% boys and 43.75% girls. The identified serogroups were B (43.75%), W135 (31.25%), A (6.25%), Y (6.25%), and undetermined (12.5%). The antibiotics used in this study were ampicillin, ceftriaxone, cefotaxime, and aqueous penicillin; the mean total treatment duration was 10 days. Purpura fulminans (37.5%), disseminated intravascular coagulopathy (31.25%), respiratory failure (25.0%), and shock (25.0%) were the commonest acute complications. Most (87.5%) of the patients survived. One patient had long-term sequelae of hearing impairment and speech delay. The mortality rate was 12.5%.
Conclusions:
Serogroup B and W-135 were 2 predominant serogroups to cause pediatric meningococcus, and the majority of infections occurred in children younger than 1 year. Continuous surveillance and prevention of meningococcal infections are of great importance.
Insights
Meningococcal infections in children are primarily caused by serogroups B and W-135, predominantly affecting infants under one year old. Continuous surveillance and prevention strategies are crucial for managing pediatric meningococcus cases.
Area of Science:
- Pediatric Infectious Diseases
- Epidemiology
- Bacteriology
Background:
- Neisseria meningitidis infections are typically severe in children but were historically sporadic in Taiwan.
- A notable increase in meningococcal infections was observed in Taiwan during 2001-2002.
- This study addresses the epidemiology and clinical features of meningococcal disease in pediatric patients.
Purpose of the Study:
- To investigate the epidemiology of meningococcal infections in a pediatric population in Taiwan.
- To describe the clinical manifestations and outcomes of meningococcal disease in children.
- To identify predominant serogroups and risk factors in pediatric cases.
Main Methods:
- Retrospective review of medical charts of pediatric patients with meningococcal disease from July 1998 to December 2005.
- Analysis of patient demographics, serogroups, clinical diagnoses, treatments, and complications.
- Evaluation of patient outcomes, including survival and long-term sequelae.
Main Results:
- Sixteen pediatric cases of meningococcal disease were identified, with ages ranging from 1 month to 15 years.
- Serogroups B (43.75%) and W-135 (31.25%) were the most prevalent.
- Common acute complications included purpura fulminans (37.5%) and disseminated intravascular coagulopathy (31.25%); the mortality rate was 12.5%.
Conclusions:
- Serogroups B and W-135 are the primary causes of pediatric meningococcal infections in the studied population.
- Infants under one year of age represent the majority of affected children.
- Ongoing surveillance and preventive measures are essential for controlling meningococcal disease in children.
