AIM: New conjugate vaccine for Streptococcus pneumoniae has been introduced in Malaysia recently. Information on infection due to S. pneumoniae in Malaysian children is scarce. We conducted a retrospective chart review of childhood invasive pneumococcal disease (IPD) presented to a single centre in Malaysia. METHODS: A retrospective review of 5 years and 4 months of all cases of IPD in children younger than 14 years of age (May 1999-August 2004) seen at the University of Malaya Medical Centre (UMMC), Kuala Lumpur, was conducted. Cases were identified from the record of Department of Medical Microbiology, UMMC. RESULTS: IPD was identified in 50 children (median age 1.1 years, range 2 weeks-14 years) during the study period. Seventy-six per cent of the cases were younger than 2 years of age. Pattern of infections noted include definite pneumonia (n = 8), probable pneumonia (n = 33), meningitis (n = 4), bacteraemia without focus (n = 4) and septic arthritis (n = 1 each). Pre-morbid diseases were present in 28% of all cases. Complications (n = 12, 24%) due to IPD were seizures (n = 5), pleural effusion/empyema (n = 4), cerebral palsy (n = 2) and deafness (n = 1). No deaths were attributed to IPD. Sixty-two per cent of the pneumococcal isolates were penicillin non-susceptible and were detected throughout the study period. CONCLUSIONS: IPD is associated with high morbidity, particularly among young children. Majority of the isolates were penicillin-non-susceptible strains. Additional information on the serotype of S. pneumoniae isolated is necessary to assess the potential impact of immunisation on preventing pneumococcal infection in Malaysia. 相似文献

Objective: To describe symptoms, disease manifestations and outcome of invasive pneumococcal disease in children prior to implementation of the pneumococcal vaccine. Patients and methods: Analysis of children younger than 16 years of age with invasive pneumococcal disease (IPD; n = 119). Children with culture‐confirmed IPD, without underlying illness at risk for invasive disease, were included. Results: IPD in 90 children (age: median 2, mean 3.2 years) included 15 with meningitis, 16 with septicaemia, 14 with bacteraemia, 24 with pneumonia and 21 with skin, bone and joint infections. Symptoms of IPD most often described were fever and gastrointestinal symptoms (abdominal pain, vomiting, or diarrhoea), and coughing. More than 90% of children with pneumonia were coughing. Most importantly, clinical signs significantly predictive for severe IPD included tachycardia for sepsis, tachypnea for pneumonia, and meningeal signs for meningitis. Leukocyte, neutrophil and platelet counts were lower and C‐reactive protein concentrations were higher on admission in children with complicated than in children with uncomplicated IPD but, due to wide overlap of these numbers, the difference was not of prognostic help to predict clinical course and outcome. Overall, 40% of children with IPD manifested complications and IPD showed a mortality rate of 6.6%. Conclusions: IPD is a serious disease with a high complication rate and mortality. The clinical signs tachycardia, tachypnea, and meningism were highly predictive for severe IPD. The initial clinical presentation and laboratory evaluation were mostly unpredictable with respect to complications and outcome in contrast to the clinical signs. 相似文献

AIMS: To evaluate the incidence, spectrum of clinical manifestations, and outcome of invasive pneumococcal disease (IPD) in children. To determine the major serogroups of Streptococcus pneumoniae responsible for invasive disease and the potential coverage by the new pneumococcal conjugate vaccines. METHODS: Analysis of prospectively recorded information of all children admitted to two teaching hospitals in Nottingham with IPD between January 1980 and December 1999. RESULTS: A total of 266 episodes of IPD in children were identified; 103 (39%) were aged <1 year and 160 (60%) <2 years. Major clinical presentations were meningitis in 86 (32%), pneumonia in 82 (31%), and bacteraemia without an obvious focus in 80 (30%). The age specific mean annual incidence rates of IPD overall among children aged <1, <2, and <5 years were 47.1, 37.8, and 20 per 100 000 population, respectively. Mortality rates for children with meningitis and non-meningitic infection were 20% and 7%, respectively. Neurological sequelae following meningitis were documented in 16 (26%) of the 61 survivors assessed. The potential coverage rates in children between the ages of 6 months and 5 years are 84% by the 7-valent, 91% by the 9-valent, and 95% by the 11-valent conjugate vaccines. CONCLUSION: This study indicates that inclusion of a pneumococcal conjugate vaccine in the primary immunisation programme in the UK would have a considerable effect on the mortality and morbidity associated with IPD. 相似文献
