[Clinical effects of low-dose and long-term erythromycin in diffuse panbronchiolitis with chronic respiratory failure].
We studied the effects of erythromycin (EM) in diffuse panbronchiolitis (DPB) with chronic respiratory failure. Seventeen patients with DPB or sinobronchial syndrome receiving home oxygen therapy (HOT) were treated with EM of 400-600 mg/day for twelve months. Five patients discontinued HOT, and hypoxemia was improved in five other patients. Clinical effects were evident at one month after the start of EM administration, and a stable state was achieved after six months of EM therapy. FEV1 was significantly increased in pulmonary function tests. Factors which influenced the effects of EM included the period between onset of clinical symptoms and commencement of HOT and/or between commencement of HOT and administration of EM. EM was effective for patients with obstructive, but not constrictive impairment in pulmonary function tests. These findings indicate that EM is effective for DPB even in patients with chronic respiratory failure.
