Sars-Cov-2 Infection In A Pediatric Patient With Cystic Fibrosis

Background: Cystic fibrosis (CF) is a potentially mortal disease characterized by a chronic pulmonary disease with persistent airway infection. Children with this disease are more susceptible to respiratory infections due to the limitation in mucociliary transport and anatomical disruption of the bronchial tree. SARS-CoV-2 causes COVID-19, a respiratory illness related to exacerbations of chronic pulmonary pathologies in children, such as CF and asthma. There are not enough case reports on pediatric patients with SARS-CoV-2 infection and CF, for which we share our experience. Case report: A 22-month-old male patient diagnosed with CF presented in the hospital with cough, fever, and increased respiratory work. The patient received supplemental oxygen and antibiotic and antiviral therapy. Positive results for type B influenza and RT-PCR (reverse transcription-polymerase chain reaction) for SARS-CoV-2 were obtained. Due to the persistence of respiratory difficulty, high-flow therapy was initiated, with a good response. After an episode of hypoxemia, bradycardia, and increased respiratory work secondary to accumulated secretions, orotracheal intubation and invasive mechanical ventilation were performed. The patient evolved with clinical and gasometric improvement. After 10 days of in-hospital antibiotic management with adequate clinical evolution, the patient was discharged to complete oral treatment and home isolation. Conclusions: We present a case of chronic respiratory disease and SARS-CoV-2 infection with severity criteria in a pediatric patient. The evolution was favorable with timely support management and antibiotic therapy in a third-level hospital.
