Diffuse panbronchiolitis (DPB) is an inflammatory lung disease of unknown cause. It is a severe, progressive form of bronchiolitis, an inflammatory condition of the bronchioles (small air passages in the lungs). DPB causes severe inflammation and nodule-like lesions of terminal bronchioles, chronic sinusitis, and intense coughing with large amounts of sputum production. The disease is believed to occur when there is susceptibility, or a lack of immune system resistance, to DPB-causing bacteria or viruses, caused by several genes that are found predominantly in individuals of East Asian descent. DPB occurs more often in males, and usually begins around age 40. It was recognized as a distinct new disease in the early 1960s, and was formally named "diffuse panbronchiolitis" in 1969. If left untreated, DPB progresses to bronchiectasis, an irreversible lung condition that involves enlargement of the bronchioles, and pooling of mucus in the bronchiolar passages. The eventual result of untreated DPB can lead to respiratory failure and heart problems. Daily treatment of DPB with macrolide antibiotics such as erythromycin eases symptoms and increases survival time, but the disease has no known cure. (more...)
