Antibiotic may help manage COPD

A low-dose antibiotic could help treat corticosteroid-resistant COPD, Australian research suggests.

Azithromycin effectively reduced epithelial cell damage in COPD patients by blocking the production of a T-cell toxin that glucocorticosteroids were powerless to suppress, according to the small study involving 11 patients.

A 250mg oral dose of azithromycin for five days, then twice-weekly for three months, markedly reduced the production of the T-cell toxin granzyme B in airways
