Bronchoscopically administered recombinant human DNase for lobar atelectasis in cystic fibrosis*

Abstract: Lobar atelectasis is a common complication of cystic fibrosis. The majority of cases respond to intravenous antibiotics and chest physiotherapy. In a subgroup of patients, atelectasis is resistant to medical therapy, and its persistence in the pediatric population is associated with a poor prognosis. Bronchoscopic instillation of human recombinant DNase expanded atelectatic lobes in three children resistant to at least 2 weeks of medical therapy. This method of administration of DNase has been successful in re… Show more

“…68 Less is known about effectiveness in the acute setting, although it has been instilled bronchoscopically to treat persistent lobar atelectasis unresponsive to IV antibiotics and chest physiotherapy. 69,70 Another agent, N-acetylcysteine (mucomyst), depolymerizes mucus in vitro. 71 A metaanalysis, reviewing both nebulized and oral administration, demonstrated minimal to no benefit with either route.…”

“…During acute pulmonary exacerbation, Dornase alfa appears to be safe and well tolerated but does not show a statistically significant therapeutic effect when added to antibiotics and physiotherapy [91]. However, bronchoscopic instillation of Dornase alfa has been used successfully for lobar atelectasis in CF, which is unresponsive to medical therapy [92].…”
