COVID-19-associated pneumonia in Swyer-James-MacLeod syndrome: A case report

Coronavirus disease 2019 (COVID-19) exerts differential effects on various individuals. The majority of infected individuals experience mild-to-moderate disease and usually recover, without requiring hospitalization. It has been reported that those who have underlying chronic diseases are more susceptible to infection and may thus develop significantly more serious illness. As a result, COVID-19 may aggravate pre-existing respiratory illnesses, such as interstitial lung disease, chronic obstructive pulmonary disease and asthma. Swyer-James-MacLeod syndrome is an uncommon clinical condition marked by post-infectious infantile bronchiolitis obliterans. Traditionally, the diagnosis is made in infancy following an investigation for reoccurring respiratory infections, although in rare cases, the diagnosis is made in adulthood. The present study describes the case of a 45-year-old patient with Swyer-James-MacLeod syndrome hospitalized due to COVID-19, which is the first one to be reported. To the best of our knowledge, there are currently no data available on the effects of COVID-19 in these individuals, stheir optimal therapy, or the impact of COVID-19 vaccination on their clinical course. Thus, it is hoped that the present study sheds some light into this condition.
