Comorbidities:
Fifteen (13%) patients diagnosed with asthma/wheezing were previously followed-up. Of 113 patients, 2 were followed-up for prematurity, 1 for congenital hypothyroidism, and 1 for gastroesophageal reflux disease (GERD). During hospitalization, three (2.7%) patients were diagnosed with selective IgA deficiency (n=1, CCAP and n=2, CAP), and one (0.9%) of three children presented with transient hypogammaglobulinemia. One patient presented with ASD on echocardiogram (ECHO) and one with PDA based on the presence of heart murmur. Hence, comorbidities are not significant risk factors for the development of CCAP (p=0.243) (Table-1).
Due to secondary pulmonary hypertension (PHT) on ECHO, inhaled iloprost was administered to one patient who received IMV in the PICU due to CCAP and who was followed-up. With appropriate antibiotic therapy and respiratory support, PHT improved; thus, treatment with inhaled iloprost was discontinued. Two patients were diagnosed with GERD during hospitalization based on clinical and radiological findings, and their complaints improved with appropriate treatment during follow-up. One patient with FBA who was followed-up for CCAP and whose anamnesis was suspicious underwent rigid bronchoscopy, and YC was removed. One patient with GT implantation who received TPA due to PPE and NO developed pneumatocele. However, the condition improved with appropriate antibiotic therapy during follow-up. One patient who received treatment for LA presented with BPF, and surgery was performed because the patient was symptomatic. Nevertheless, none of the patients underwent lobectomy.
