Background: Childhood pneumonia is an important cause of morbidity in the developed world and morbidity
and mortality in the developing world. One of the challenges in planning the treatment of respiratory tract
infection in children is identifying the causative agent. The Community Acquired Pneumonia (CAP) presents
both a diagnostic and therapeutic challenge to clinicians.
Aims of the Study: To obtain the epidemiological profile, identify some etiological factors , assess the
clinical presentations, x-ray findings and laboratory investigations of children with lower respiratory tract
infection at Child’s Central Teaching Hospital in Baghdad.
Patients and Method: A total of 86 children were included in the study. we investigate the etiology of acute
lower respiratory tract infection in children under two years admitted to central child teaching hospital for
a period of three months in winter. Antibodies of RSV and Chlamydia Pneumonitis were detected using
Results: Whereas 38 of the children (44%) were diagnosed with pneumonia caused by Chlamydia
pneumonitis. RSV was detected in 14 (16%) and 30 (35%) had combined infection .Age of most of the
patients was between one and six months with male predominance. CRP was negative(79%) in the majority
of our patients ,only 3 patients had lower positive titers. WBC differential count show predominance of
lymophocytosis (58%) ,which is compatible with viral and atypical lower respiratory tract infection .
Conclusion: The identification of the cause of ARI remains challenging, due either to inadequate samples
that may lead to false negative results, or to difficult interpretation of positive findings between infection
and colonization. In our study the highest rate of acute lower respiratory tract infection was between age of
one and six months with predominance of male sex. Chlamydia microorganism was found in 44% of such
patients with lower respiratory tract infection. Further studies are needed to identify other possible agents of
ARI (e.g., influenza, adenoviruses, other bacterial infections) in this population and to better understand the
causal role of atypical bacteria detected in respiratory samples.
