Background and aims Lower tract respiratory infections (LTRI) are very frequent in paediatric population. We collected epidemiological, etiological and clinical data and correlated them to some variables.
Methods We performed an observational study of all children with a LTRI, admitted to our Paediatric Unit from February 2013 to January 2014. The population was grouped in three classes of ages (0–2yr, 3–6yr, >6yr). All patients underwent to a questionnaire focused on exposition to protective and risk factors for respiratory diseases.
Results 83 children were included. We grouped them according to discharge diagnosis and analysed the distribution for ages, sex and season of onset. At the admission 18 patients had respiratory distress; O2 therapy was necessary for 11 of them, infusion therapy for 40, endovenous antibiotic therapy for 34.
Swabs were positive in 1 case for Parainfluenza viruses and in 2 for S. Aureus; sierological tests were positive in 5 cases for Mycoplasma Pneumoniae, in 2 for Chlamydia Pneumoniae, in 1 for ParvovirusB19, in 1 for Coxsackievirus. In 28 patients (33%) exposition to passive smoke was observed, in 17 (20%) to aeroallergens and in 33 (40%) a personal or familiar story of atopy.
Conclusions Our experience showed a higher prevalence of LTRI in males (63%), in winter (35%) and spring (33%), without a difference between preschool and school age children.
