Abstract
ntroduction: Streptococcal pneumoniae, is the most common pathogen causing
community acquired pneumonia (CAP) among children.
Aim of work: To estimate the rate,mortality and burden of streptococcal
Community acquired pneumonia in children more than 2months and less than12
years old using PCR.
Patients and methods: This is a cross-sectional study which included children more
than 2 months and less than 12 years old, complaining of clinical picture of
pneumonia who were admitted at the Emergency Department of Pediatric
Hospital, Cairo University. All the included children were subjected to full history
taking, clinical examination and investigations including PCR for streptococcal
infection.
Results: There is statistically significant association between Positive PCR for
streptococci and increased age of children with p-value=0.04,lower weight with pvalue=0.01 and severe malnutrition with p-value=0.046. Fever was the commonest
presenting symptom (41.8%) and all showed picture of infiltrates and
consolidations (100%) and only 1.09% had pleural effusion in radiological
investigations. Blood culture results of the included children were positive in 6.6%
(4.4% CONS and 2.2% klebsiella), and sputum PCR for streptococci was positive
in 18.6% of the included children. The majority of the included children with
pneumonia (95.6%) admitted to PICU, 29.7% of them needed mechanical
ventilation,11% died while 89% survived
