Co-infection of SARS-CoV-2 and Bordetella bronchiseptica in a young man with idiopathic non-cystic bronchiectasis and vitamin D3 deficiency

Abstract

This is the first reported case, to our knowledge, of co-infection of Bordetella bronchiseptica and SARS-CoV-2 in a young patient with underlying idiopathic bronchiectasis and vitamin D3 deficiency that was treated successfully with a combination therapeutic regime integrating doxycycline, empiric therapies for COVID-19, vitamin D supplementation, and supportive ICU care. Large prospective studies are required to investigate further the role of co-infections in COVID-19 patients with bronchiectasis. Randomized control trials should examine the putative beneficial role of vitamin D supplementation in patients with COVID-19.
