JAMA 309: 1260–1267, 2013. For patients with alpha-1 antitrypsin deficiency: Replacement therapy. Bronchiectasis may be, Diffuse: Affecting many areas of the lungs, Focal: Appearing in only 1 or 2 lung areas. The most common presenting symptom is chronic cough that produces thick, tenacious, often purulent sputum. Bronchiectasis is a structural airway disease characterized by dilated bronchi and bronchioles due to severe or recurrent lower airways inflammation. What inflames the small airways depends on the etiology of bronchiectasis. So in bronchiectasis chronic inflammation causes the bronchi and bronchioles to get damaged and dilated. For patients with allergic bronchopulmonary aspergillosis: Corticosteroids and sometimes azole antifungals. Its use is similar to such commonly used terms as urinary infection, congenital heart disease, or allergy. Can cause bronchiectasis, sinusitis, otitis media, and male infertility, 50% of patients with primary ciliary dyskinesia (PCD) have situs inversus, Kartagener syndrome (clinical triad of dextrocardia, sinus disease, situs inversus), Causes viscous secretions due to defects in sodium and chloride transport, Often complicated by P. aeruginosa or S. aureus colonization, Hypogammaglobulinemia, particularly common variable immunodeficiency, Human immunodeficiency virus (HIV) infection, After lobar resection, due to kinking or twisting of remaining lobes, Commonly causes bronchiectasis (frequently subclinical), more often in men and in patients with long-standing RA, Bronchiectasis possibly due to increased viscosity of bronchial mucus, which leads to obstruction, poor clearance, and chronic infection, Bronchiectasis in up to 20% of patients via unclear mechanisms, Bronchopulmonary complications occurring after onset of inflammatory bowel disease in up to 85% and before onset in 10 to 15%, Bronchiectasis more common in ulcerative colitis but can occur in Crohn disease, Williams-Campbell syndrome (cartilage deficiency), Tracheobronchomegaly (eg, Mounier-Kuhn syndrome), Pulmonary sequestration (a congenital malformation in which a nonfunctioning mass of lung tissue lacks normal communication with the tracheobronchial tree and receives its arterial blood supply from the systemic circulation), Direct airway damage altering structure and function, May be secondary to frequent infection due to immunosuppression, Rare syndrome involving bronchiolitis and chronic sinusitis, May occur with advanced chronic obstructive pulmonary disease (COPD) or asthma, Due to severe gastroesophageal reflux disease or swallowing dysfunction, most commonly in the lower lobes. Macrolides are thought to be beneficial mainly due to their anti-inflammatory or immunomodulatory effects. With newer, improved genetic and immunologic testing, an increasing number of reports describe finding an etiology in these idiopathic cases after careful, systematic evaluation. 2. As for all patients with chronic pulmonary disease, recommendations include the following: Pneumococcal vaccination with both 13-valent conjugate (PCV13) and polysaccharide vaccination (PPSV23). Of these causes, which of the following is most common in patients with secondary spontaneous pneumothorax? Some patients with cystic fibrosis benefit from gene therapy targeting CFTR, which can decrease exacerbations. There are several different types of pneumothorax including primary and secondary spontaneous, traumatic, catamenial, and iatrogenic; each of these types occurs due to a different cause. Exacerbations are marked by a worsening cough and increases in dyspnea and the volume and purulence of sputum. One of the key differences from chronic bronchitis is that in bronchiectasis, the inner diameter of the airway can actually get wider. The inflammation of the bronchial walls is known as bronchitis. Cystic fibrosis (CF) is commonly associated with this condition, and previously undiagnosed CF may account for up to 20% of idiopathic cases. Patients have chronic productive cough with intermittent acute exacerbations. S. aureus colonization is strongly associated with cystic fibrosis; a culture finding of S. aureus should raise concern for undiagnosed CF. In advanced cases, hypoxemia and right-sided heart failure due to pulmonary hypertension may increase dyspnea. Focal bronchiectasis usually occurs when a large airway becomes obstructed. 0. Simultaneously, in the inflamed small and medium-sized airways, macrophages and lymphocytes form infiltrates that thicken mucosal walls. Bronchiectasis causes airways to slowly lose their ability to clear out mucus, which makes your respiratory system more vulnerable to infection. A bronchiectasis exacerbation is defined as a patient with bronchiectasis with deterioration for at least 48 hours in ≥ 3 of the following symptoms (1): Breathlessness and/or exercise intolerance. Staining and cultures of sputum for bacterial, mycobacterial (Mycobacterium avium complex and M. tuberculosis), and fungal (Aspergillus species) organisms may also help identify the cause of chronic airway inflammation. N/A. Symptoms characteristically begin insidiously and gradually worsen over years, accompanied by episodes of acute exacerbation. Bronchitis can be caused by smoking and from viral infections such as those caused by influenza A or B, parainfluenza or coronavirus. Gobs of threads to read. For patients with airway obstruction, bronchodilator therapy (eg, with some combination of a long-acting beta-adrenergic agonist, tiotropium, and a short-acting beta-adrenergic drug as indicated by symptoms and severity of lung obstruction, as used in patients with COPD) can help improve function and quality of life. The inflammatory mediators destroy elastin, cartilage, and muscle in larger airways, resulting in irreversible bronchodilation. Treatment of underlying disorders is important whenever possible. 3. Lots to do, including a daily exercise program to improve your heart/lung efficiency. Of course, it may also be due to the fact that COPD may cause bronchiectasis. Chronic obstructive pulmonary disease (COPD) and bronchiectasis are two chronic lung conditions that often co-exist in patients. Airway clearance techniques are used to reduce chronic cough in patients with significant sputum production and mucous plugging and to reduce symptoms during exacerbations. This information helps with antibiotic selection during exacerbations. The pathophysiology of bronchiectasis is not fully understood, likely in part because it is the common end-point of a heterogenous group of disorders predisposing to chronic airway inflammation. X-ray findings suggestive of bronchiectasis involve thickening of the airway walls and/or airway dilation; typical findings include ill-defined linear perihilar densities with indistinctness of the central pulmonary arteries, indistinct rings due to thickened airways seen in cross section (parallel to the x-ray beam), and “tram lines” (or tram-track sign) caused by thickened, dilated airways perpendicular to the x-ray beam. The link you have selected will take you to a third-party website. Acute exacerbations are treated with antibiotics, inhaled bronchodilators (particularly if patients are wheezing), and increased attempts at mucus clearance, using mechanical techniques, humidification, and nebulized saline (and mucolytics for patients with CF). Dlstinguishing bronchial deformity or dilatation occurs in bronchiectasis, as well as in acute and chronic bronchitis. The right middle lobe is involved most often because its bronchus is small and angulated and has lymph nodes in close proximity. no longer distinguished but helpful to separate for pathophysiologic understanding and clinical management Pneumothorax occurs when air enters the pleural space and partially or completely causes the lung to collapse. Other vascular complications include pulmonary hypertension due to vasoconstriction, arteritis, and sometimes shunt from bronchial to pulmonary vessels. Hill AT, Haworth CS, Aliberti S, et al: Pulmonary exacerbation in adults with bronchiectasis: A consensus definition for clinical research. Bronchiectasis as a diagnostic term has been misused as a catch-all for several types of pulmonary suppuration. Study review shows several associations between bronchiectasis … Bronchiectasis may also be associated with a wide variety of systemic diseases, … Five-year survival rates as high as 65 to 75% have been reported when a heart-lung or double lung transplantation is done. 2. The diagnosis of PCD should typically be done in specialized centers because evaluation can be challenging. Bronchiectasis can also be related to more common conditions, including chronic obstructive pulmonary disease (COPD), asthma, or chronic, recurrent aspiration. Pulmonary function tests for baseline evaluation and monitoring disease progression, Sputum culture for bacteria and mycobacteria to determine colonizing organisms. Symptoms are chronic cough and purulent sputum expectoration; some patients may also have fever and dyspnea. For patients with cystic fibrosis: Antibiotics and inhaled bronchodilators as well as comprehensive support, and dietary supplementation. The key treatment goals are to control symptoms and improve quality of life, reduce the frequency of exacerbations, and preserve lung function (1, 2). Eur Respir J 49:1700051, 2017. Aleksey Dvorzhinskiy 0 % Topic. Furthermore, definitions for bronchiectasis given by the clinician, the roentgenologist, and the pathologist may differ greatly. Polverino E, Gemine PC, McDonnell MJ, et al: European Respiratory Society guidelines for the management of adult bronchiectasis. Bronchiectasis is a chronic disease that gets worse over time. Bronchiectasis and bronchitis, both acute and chronic, cannot always be differentiated clinically, but characteristic bronchial deformity occurs in all three ().The bronchial deformity occurring in acquired bronchiectasis is saccular or fusiform; in acute and chronic bronchitis, it is cylindrical. While you're waiting, use the search box (top right with magnifying glass) and type in bronchiectasis. Mean yearly decrease in FEV1 is about 50 to 55 mL (normal decrease in healthy people is about 20 to 30 mL). Initial antibiotics for patients without CF and with no prior culture results should be effective against H. influenzae, M. catarrhalis, S. aureus, and S. pneumoniae. Intravenous administration is frequently required. Chronic bronchitis is thought to be caused by overproduction and hypersecretion of mucus by goblet cells. In traction bronchiectasis, pulmonary fibrosis pulls or distorts airways in ways that simulate bronchiectasis on imaging. Significant hemoptysis is usually treated with bronchial artery embolization, but surgical resection may be considered if embolization is ineffective and pulmonary function is adequate. Allergic bronchopulmonary aspergillosis, a hypersensitivity reaction to Aspergillus species that occurs most commonly in people with asthma, but sometimes in patients with CF, can cause or contribute to bronchiectasis. He smokes 1 pack of cigarettes daily for the past 45 years. In certain patients with diffuse bronchiectasis, especially cystic fibrosis, lung transplantation is also an option. Prevention of exacerbations with regular vaccinations and sometimes suppressive antibiotics, Bronchodilators and sometimes inhaled corticosteroids if reversible airway obstruction is present, Antibiotics and bronchodilators for acute exacerbations, Sometimes surgical resection for localized disease with intractable symptoms or bleeding. The legacy of this great resource continues as the Merck Manual in the US and Canada and the MSD Manual outside of North America. JAMA 309: 1251–1259, 2013. Digital clubbing is uncommon but may be present. Ann Intern Med. The evidence supporting their use and benefit is strongest in the CF population.
