The gradual progression of bronchiectasis can lead to chronic respiratory failure, chronic pulmonary heart disease, and can even endanger the life of the patient. Patients with bronchiectasis should have relevant tests to further clarify the diagnosis and assess the severity of the disease, and HRCT of the chest is required to evaluate the condition. Patients with bronchiectasis should also have an antinuclear antibody profile, as well as tests related to T-lymphocyte subsets and immunoglobulins to further evaluate the cause of bronchiectasis. If the patient has rheumatoid arthritis or a low autoimmune system, appropriate treatment is needed to prevent the progression of bronchiectasis. If no significant problems are found through the above tests, the patient’s bronchiectasis may originate from tuberculosis or from recurrent pulmonary infections in childhood, and for this group of patients, the focus of treatment is to prevent recurrent pulmonary infections and the continued aggravation of bronchiectasis. If the patient has recurrent bronchiectasis combined with infection, he can be treated with a small dose of oral roxithromycin, which can help prevent recurrent bronchiectasis infections and slow down the progression of the disease.
