Pulmonary Function Following Blastomycosis in Childhood

Abstract

In order to determine the pulmonary outcome following blastomycosis during childhood, we compiled a case series of hospitalized patients from a retrospective review with later recall for pulmonary function testing, coupled with prospective measurements of pulmonary function in three patients, at a tertiary care children's hospital. A convenience sample of five of 17 patients hospitalized with pulmonary blastomycosis, whose mean age at the time of diagnosis was 10.6 +5.5 years, was recalled at a mean of 4.5 +3.5 years after diagnosis. Three patients more recently hospitalized underwent serial pulmonary function testing (PFT) prospectively from as soon after the acute infection as their condition permitted. All but two patients had normal PFT when last seen. The two patients with persistent pulmonary sequelae were among those followed up prospectively and had more severe clinical and radiographic pictures at the outset. Pulmonary function in children who suffered from pulmonary blastomycosis is normal in most patients at follow-up years later. Severe radiographic disease and slow recovery over months portend long-term sequelae.
