Diffuse alveolar damage (DAD) (see alsoo under IIb and XVf)

Last update 01/03/2020

(Fr: dommage alveolaire diffus). Strictly speaking, DAD is a pathologic term denoting alveolar fibrin, hyaline membranes, reactive epithelial cells and varied stages of inflammation (see under 'Pathology'). Of note, hemosiderin-laden macrophages may be found in the BAL in authentic DAD cases (19129275). Nowadays, not many cases undergo a confirmatory lung biopsy. Hence DAD is more often assumed than proved on the basis of respiratory failure and diffuse haze or ground-glass on imaging (Reviews at PMID 19398592 and 20441502). To the clinician, 'clinically consistent DAD' may reflect those cases with diffuse haze, GGO and severe hypoxemia. Here and under XVf we list only those drugs with pathologically-confirmed DAD. Radiographically-diagnosed DAD must be considered as low evidence. Similar list under pathology, XVf

Causative drugs

Frequency - Incidence

Incidence of respiratory adverse event(s) due to the specific drug as assessed by number of reported/published cases in the literature. Red digits in stars indicate: 0 = Very rare, questionable signal · 1 = < 10 cases · 2 = 10-50 cases · 3 = 50–100 cases · 4 = 100-200 cases · 5 = >200 cases
