Abstract

The study aims to identify microbiological etiologies in children with severe persistent/recurrent pneumonia (sPP/RP) admitted to the Intensive Care Unit (ICU) of the National Children's Hospital. This is prospective descriptive study on 187 children with sPP/RP admitted to the ICU from November 2019 to October 2020, of whom 93 children had sRP, accounting for 49.7%, 34 children had sPP (18.2%) and 60 children had sPP+RP (32.1%). The results showed that viruses were the leading cause (48.1%), most commonly RSV (24.6%), CMV (15.5%), Rhinovirus (9.6%) and Adenovirus (7%). Bacteria accounted for 32.6%, in children of severe recurrent pneumonia (sRP), the prominent pathogens were the cause of community-acquired pneumonia: Haemophilus influenzae (33.3%), Streptococcus pneumonia (16.7%), Staphylococcus aureus (16.7%). In the severe persistent pneumonia group (sPP and sPP+RP), the main pathogens detected were Staphylococcus aureus (47.1% in the sPP group; 25% in the sPP+RP group) and gram-negative causing ventilator-associated pneumonia: Klebsiella pneumonia (17.7% in the sPP group; 15% in the sPP+RP group), Acinetobacter baumannii (11.8% in the sPP group; 25% in the sPP+RP group), Pseudomonas aeruginosa (5.9% in the sPP group, 10% in the sPP+RP group). Additionally, 5.3% had PCP, while tuberculosis and other fungi were found at low rates (2.7% and 3.2%, respectively).
