Bronchial amyloidosis successfully treated with low-dose long-term erythromycin therapy

A 69-year-old man was admitted for evaluation of an abnormal chest X-ray. A diagnosis of primary bronchial amyloidosis was made on the basis of the chest X-ray, CT scans and bronchial biopsy specimens. The patient was treated with low-dose long-term erythromycin therapy (600 mg/day). After four months of therapy, chest CT scans, bronchoscopic findings and bronchial biopsy specimens revealed significant improvement of inflammatory changes. Low-dose erythromycin therapy may be helpful in terms of its anti-inflammatory effects for patients with bronchial amyloidosis.
