Among patients with positive sputum culture for tuberculosis prior to starting LZD.
Capreomycin (n = 3; 63 susceptible at baseline), ethambutol (n = 1; 7 susceptible at baseline), ofloxacin (n = 2; 17 susceptible at baseline), 1 patient with acquired drug resistance to ethambutol and ofloxacin.
Capreomycin (n = 1; 60 susceptible at the time LZD started).
Lobectomy (n = 8), segmentectomy (n = 6), pulmonectomy (n = 2)
The median length of treatment prior to loss to follow-up = 380 days; last sputum culture-positive (n = 2).
LZD = linezolid; IQR = interquartile range.
