bronchiectasis vs chronic bronchitis usmle

early classifications distinguished chronic bronchitis and emphysema . Treat exacerbations with antibiotics, bronchodilators, more frequent airway clearance measures, and corticosteroids. Serisier DJ, Martin ML, McGuckin MA, et al: Effect of long-term, low dose erythromycin on pulmonary exacerbations among patients with non-cystic fibrosis bronchiectasis: the BLESS randomized controlled trial. 1). 0. This is the key difference between bronchitis and bronchiectasis, … The two diseases share many similarities but there are some important differences between them. 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. Bronchiectasis as a diagnostic term has been misused as a catch-all for several types of pulmonary suppuration. This lasts a few weeks and usually goes away on its own. Bronchiectasis is a chronic condition where the walls of the bronchi are thickened from inflammation and infection in the bronchi. Prevent exacerbations using appropriate immunizations, airway clearance measures, and sometimes macrolide antibiotics. 2. Common organisms include. He has been coughing for the past 2 months and is associated with mucopurulent and tenacious sputum production, which has progressively worsened. Medical history is significant for chronic obstructive pulmonary disease. The right middle lobe is involved most often because its bronchus is small and angulated and has lymph nodes in close proximity. 1. Patients with CF have the poorest prognosis, with a median survival of 36 years, and most patients continue to have intermittent exacerbations. A complete blood count (CBC) and differential can help determine the severity of disease activity and identify eosinophilia, which may suggest complicating diagnoses. 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. More will chime in. The term is useless for both communication and antibiotic decision. 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. Diffuse bronchiectasis develops most often in patients with genetic, immunologic, or anatomic defects that affect the airways. Lancet 380: 660–667, 2012. Bronchiectasis causes airways to slowly lose their ability to clear out mucus, which makes your respiratory system more vulnerable to infection. Chronic Bronchitis ... Bronchiectasis. Focal bronchiectasis usually occurs when a large airway becomes obstructed. For patients with allergic bronchopulmonary aspergillosis: Corticosteroids and sometimes azole antifungals. In the same class as COPD and emphysema, bronchiectasis is a chronic obstructive lung condition that leads to pulmonary inflammation and infection. Even chronic bronchitis is not necessarily permanent if patients take the appropriate measures like quitting cigarette smoking at an early stage. chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation due to mixture of small airway disease and parenchymal destruction. Primary ciliary dyskinesia should be considered if adults with bronchiectasis also have chronic sinus disease or otitis media, particularly if problems have persisted since childhood. Of course, it may also be due to the fact that COPD may cause bronchiectasis. Bronchiectasis in such patients may have right middle lobe and lingular predominance, and infertility in males or dextrocardia may be present. Dyspnea and wheezing are common, and pleuritic chest pain can develop. "Tram lines" are easily visible on CT. As airway damage increases over time, bronchiectasis changes progress from cylindrical to varicose and then cystic findings on imaging. Gobs of threads to read. We do not control or have responsibility for the content of any third-party site. That may seem like a good thing but it isn’t. Ann Intern Med. Cancel Save. The increasing availability and use of c-HRCT has shown that up to 50% of patients with severe COPD will have co-existent bronchiectasis. The key treatment goals are to control symptoms and improve quality of life, reduce the frequency of exacerbations, and preserve lung function (1, 2). Immunodeficiencies such as common variable immunodeficiency (CVID) may also lead to diffuse disease, as may rare abnormalities in airway structure. Bronchiectasis is dilation and destruction of larger bronchi caused by chronic infection and inflammation. One of the key differences from chronic bronchitis is that in bronchiectasis, the inner diameter of the airway can actually get wider. PPSV23 revaccination is recommended 5 years later in patients who are < 65 at the time of their initial pneumococcal vaccination and for patients who are asplenic or immunosuppressed. The most common presenting symptom is chronic cough that produces thick, tenacious, often purulent sputum. The bronchial deformity occurring in acquired bronchiectasis is saccular or fusiform; in acute and chronic bronchitis, it … The New England Journal of Medicine 346:1383–1393, 2002 and O'Donnell AE: Medical management of bronchiectasis. Bronchiectasis may also be associated with a wide variety of systemic diseases, … Chronic macrolide therapy reduces acute exacerbations in patients with bronchiectasis, and can slow the decline in lung function in patients with CF (3–5). What inflames the small airways depends on the etiology of bronchiectasis. Chronic bronchitis may mimic bronchiectasis clinically, but bronchiectasis is distinguished by increased purulence and volume of daily sputum and by dilated airways shown on imaging studies. Digital clubbing is uncommon but may be present. The Bronchiectasis Severity Index (BSI), which uses a combination of clinical, radiological and microbiological features, is a strong predictor of morbidity and mortality and predicts one and four year morbidity and mortality (Chalmers et al 2014) for patients with non-CF bronchiectasis. Intravenous administration is frequently required. 7. In advanced cases, hypoxemia and right-sided heart failure due to pulmonary hypertension may increase dyspnea. Bronchiectasis causes airflow limitation (reduced forced expiratory volume in 1 sec [FEV1] with reduction in the FEV1/FVC ratio); the FEV1 may improve in response to beta-agonist bronchodilators. Learn more about bronchiectasis symptoms, causes, diagnosis, and treatment. 5. Bronchiectasis can occur as a result of chronic pulmonary aspiration. As the disease progresses, chronic inflammation and hypoxemia cause neovascularization of the bronchial (not the pulmonary) arteries. Copyright © 2021 Lineage Medical, Inc. All rights reserved. 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. Bronchiectasis can frequently occur in parallel with more common forms of chronic lung disease including COPD and asthma. 6. Bronchiectasis can be broken down into “Bronchi” which refers to the bronchi and bronchiole airways of the lower lungs, and “-ectasis” means a dilation or expansion.. Nicholson CH, Holland AE, Lee AL: The Bronchiectasis Toolbox - A Comprehensive Website for the Management of People with Bronchiectasis. Treatment of underlying disorders is important whenever possible. 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. Undernutrition and human immunodeficiency virus (HIV) infection also appear to increase risk. For patients with cystic fibrosis: Antibiotics and inhaled bronchodilators as well as comprehensive support, and dietary supplementation. Bronchiectasis is an irreversible and abnormal dilation in the bronchial tree that is generally caused by cycles of bronchial inflammation in addition to … Inhaled or oral corticosteroids are frequently given to treat airway inflammation and worsening airway obstruction. Pulmonary function tests for baseline evaluation and monitoring disease progression, Sputum culture for bacteria and mycobacteria to determine colonizing organisms. JAMA 309: 1251–1259, 2013. Other vascular complications include pulmonary hypertension due to vasoconstriction, arteritis, and sometimes shunt from bronchial to pulmonary vessels. But with proper care and treatment, you can manage it. In patients with infections caused by these organisms, treatment is with multiple antibiotics (eg, tobramycin, aztreonam, ticarcillin/clavulanate, ceftazidime, cefepime). Yet, the chances of concurrent COPD and bronchiectasis are slim: while COPD is the third leadin… Study review shows several associations between bronchiectasis … 0. med BULLETS Step 1. Five-year survival rates as high as 65 to 75% have been reported when a heart-lung or double lung transplantation is done. Acute exacerbations are common and frequently result from new or worsened infection. Due to the inflammation in both conditions, the … Data from Barker, AF: Bronchiectasis. The resulting inability to clear secretions leads to a cycle of infection, inflammation, and airway wall damage. Acute bronchitis. The diagnosis of PCD should typically be done in specialized centers because evaluation can be challenging. 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. N/A. JAMA 309: 1260–1267, 2013. Mean yearly decrease in FEV1 is about 50 to 55 mL (normal decrease in healthy people is about 20 to 30 mL). This information helps with antibiotic selection during exacerbations. TOPICS. The evidence supporting their use and benefit is strongest in the CF population. Clinically significant nontuberculous mycobacterial infection is diagnosed by finding high colony counts of these mycobacteria in cultures from serial sputum samples or from bronchoalveolar lavage fluid in patients who have granulomas on biopsy or concurrent radiologic evidence of disease. 4. 3 The research suggests that approximately 52% of COPD patients also reported bronchiectasis-related symptoms and that the chronic pulmonary condition was more prevalent in women than in men. Drug therapy is typically continued until sputum cultures have been negative for 12 months. Tests may include the following: Serum immunoglobulins (IgG, IgA, IgM) and serum electrophoresis to diagnose common variable immunodeficiency, Targeted assessment of baseline and specific antibody responses to peptide and polysaccharide antigens (ie, tetanus, capsular polysaccharide of S. pneumoniae and H. influenzae type b) done to assess immune responsiveness, Two sweat chloride tests and CFTR gene mutation analysis to diagnose cystic fibrosis (including in adults > 40 years without an identifiable cause of bronchiectasis, especially those with upper lobe involvement, malabsorption, or male infertility), Rheumatoid factor, antinuclear antibody (ANA), and antineutrophil cytoplasmic antibody testing if an autoimmune disorder is being considered, Serum IgE and Aspergillus precipitins if patients have eosinophilia, to rule out allergic bronchopulmonary aspergillosis, Alpha-1 antitrypsin level to evaluate for alpha-1 antitrypsin deficiency if high-resolution CT shows lower lobe emphysema. Bronchiectasis and bronchitis, both acute and chronic, cannot always be differentiated clinically, but characteristic bronchial deformity occurs in all three (Fig. Bronchiectasis is more commonly seen with history of recurrent URIs and copious mucopurulent sputum. Inhaled antibiotics (amikacin, aztreonam, ciprofloxacin, gentamicin, colistin, or tobramycin) can reduce sputum bacterial load, and may also reduce the frequency of exacerbations. Chronic bronchitis. Please confirm that you are a health care professional. Here is another fact to consider. During childhood, common infecting organisms are S. aureus and H. influenzae, and quinolone antibiotics such as ciprofloxacin and levofloxacin may be used. J Clin Immunol 31: 315–322, 2011. N/A. Mycobacteria (tuberculous or nontuberculous) can both cause focal bronchiectasis and colonize the lungs of patients with bronchiectasis due to other disorders (see table Factors Predisposing to Bronchiectasis). Of these causes, which of the following is most common in patients with secondary spontaneous pneumothorax? Learn more about our commitment to Global Medical Knowledge. During an exacerbation-free period, all patients should have expectorated or induced sputum cultured to determine the predominant colonizing bacteria and their sensitivities. Private Note. Over time, the walls of the bronchi thicken and mucus builds up, scarring and damaging the lungs. Airway clearance techniques are used to reduce chronic cough in patients with significant sputum production and mucous plugging and to reduce symptoms during exacerbations. The Merck Manual was first published in 1899 as a service to the community. In developing countries, most cases are probably caused by tuberculosis, particularly in patients with impaired immune function due to undernutrition or human immunodeficiency virus (HIV) infection. A 68-year-old man presents to his primary care physician for a cough. Macrolides are thought to be beneficial mainly due to their anti-inflammatory or immunomodulatory effects. For example, azithromycin, 500 mg po 3 times/week or 250 mg orally once a day has been used, but the optimal dose is unknown. Exacerbations are marked by a worsening cough and increases in dyspnea and the volume and purulence of sputum. ... Everett M.T. For somebody with bronchiectasis, life expectancy can be a significant concern. Hemoptysis, which can be massive, occurs due to airway neovascularization. Bronchiectasis can also be related to more common conditions, including chronic obstructive pulmonary disease (COPD), asthma, or chronic, recurrent aspiration. What is the difference in presentation between bronchiectasis vs. chronic bronchitis? Nonspecific structural defects can be present in up to 10% of cilia in healthy people and in patients with pulmonary disease, and infection can cause transient dyskinesia. This inflammation can progress, causing recurrent exacerbations and worsen airflow limitation on pulmonary function tests. Nasal or oral exhaled nitric oxide level is frequently low. of images. 2 2. Dilated airways filled with mucous plugs can also cause scattered elongated, tubular opacities. Pulmonary function tests can be helpful for documenting baseline function and for monitoring disease progression. The trusted provider of medical information since 1899. In bronchiectasis, chronic inflammation from various causes destroys elastin, cartilage, and muscle in larger airways, resulting in irreversible damage and dilated airways that are chronically colonized by infectious organisms. (1986) Bronchitis, Bronchiolitis and Bronchiectasis. Low-grade fever and constitutional symptoms (eg, fatigue, malaise) may also be present. 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. Quinti I, Sorellina A, Guerra A, et al: Effectiveness of immunoglobulin replacement therapy on clinical outcome in patients with primary antibody deficiencies: Results from a multicenter prospective cohort trial. As for finding folks to connect with who have bronchiectasis, you're in the right place. Congenital defects in mucociliary clearance such as primary ciliary dyskinesia (PCD) syndromes may also be a cause, explaining almost 3% of previously idiopathic cases. 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. Patients with known P. aeruginosa colonization or more severe exacerbations should receive antibiotics effective against this organism (eg, ciprofloxacin 500 mg po bid, levofloxacin 500 mg po once/day for 7 to 14 days) until repeat culture results are available. The link you have selected will take you to a third-party website. Focal bronchiectasis typically develops as a result of untreated pneumonia or obstruction (eg, due to foreign bodies, tumors, postsurgical changes, lymphadenopathy). In fact, a peer-reviewed study was conducted to examine the occurrence of non-cystic fibrosis bronchiectasis among U.S. adults in 2013. For more severely ill patients, a CBC, chest x-ray, and possibly other tests may be warranted to exclude common complications of serious pulmonary infection, such as lung abscess and empyema. With disease progression, inflammation spreads beyond the airways, causing fibrosis of the surrounding lung parenchyma. Surgical resection is rarely needed but may be considered when bronchiectasis is localized, medical therapy has been optimized, and the symptoms are intolerable. People with bronchiectasis have periodic flare-ups of … 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. verify here. J Thorac Dis 10 (Suppl 28): S3428–S3435, 2018. Animated Mnemonics (Picmonic): https://www.picmonic.com/viphookup/medicosis/ - With Picmonic, get your life back by studying less and remembering more. SUMMARY. 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). 0. In certain patients with diffuse bronchiectasis, especially cystic fibrosis, lung transplantation is also an option. Eur Respir J 50: 1700629, 2017. doi: 10.1183/13993003.00629-2017. With newer, improved genetic and immunologic testing, an increasing number of reports describe finding an etiology in these idiopathic cases after careful, systematic evaluation. Diffuse bronchiectasis occurs when a causative disorder triggers inflammation of small and medium-sized airways, releasing inflammatory mediators from intraluminal neutrophils. Altenburg J, de Graaf CS, Stienetra Y, et al: Effect of azithromycin maintenance treatment on infectious exacerbations among patients with non-cystic fibrosis bronchiectasis: The BAT randomized controlled trial. So in bronchiectasis chronic inflammation causes the bronchi and bronchioles to get damaged and dilated. For patients with mild to moderate exacerbations, repeat sputum cultures to confirm the causative organism and sensitivity patterns may be sufficient. Lack of normal bronchial tapering can result in visible medium-sized bronchi extending almost to the pleura. In the case of immune deficiency (particularly CVID), autoimmune inflammation may also contribute. Radiographic patterns may differ depending on the underlying disease; bronchiectasis due to cystic fibrosis develops predominantly in the upper lobes, whereas bronchiectasis due to an endobronchial obstruction causes more focal x-ray abnormalities. 2011 Jul 19. Patients should be taught these techniques by a respiratory therapist and should use whichever one is most effective and sustainable for them; no evidence favors one particular technique. 3. Aleksey Dvorzhinskiy 0 % Topic. Inhaled corticosteroids may also be used in patients with frequent exacerbations or marked variability in lung function measurements (ie, reversible airway obstruction following bronchodilator administration), but their role remains controversial. Colonization by multiple organisms is common, and antibiotic resistance is a concern in patients who require frequent courses of antibiotics for treatment of exacerbations. To add to the confusion, a flare-up of chronic bronchitis may be called acute bronchitis, and in America wheezy bronchitis is called acute bronchitis. Furthermore, definitions for bronchiectasis given by the clinician, the roentgenologist, and the pathologist may differ greatly. Bronchitis can be caused by smoking and from viral infections such as those caused by influenza A or B, parainfluenza or coronavirus.
