bronchiectasis vs chronic bronchitis usmle

Flume PA, Mogayzel PJ Jr, Robinson KA, et al: Cystic fibrosis pulmonary guidelines: Treatment of pulmonary exacerbations. In advanced cases, hypoxemia and right-sided heart failure due to pulmonary hypertension may increase dyspnea. Diffuse bronchiectasis sometimes complicates common autoimmune disorders, such as rheumatoid arthritis or Sjögren syndrome, and can occur in the setting of hematologic malignancy, organ transplant, or due to the immune compromise associated with treatment in these conditions. J Clin Immunol 31: 315–322, 2011. Of course, it may also be due to the fact that COPD may cause bronchiectasis. 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. Other vascular complications include pulmonary hypertension due to vasoconstriction, arteritis, and sometimes shunt from bronchial to pulmonary vessels. Pulmonary function tests can be helpful for documenting baseline function and for monitoring disease progression. Over time, the walls of the bronchi thicken and mucus builds up, scarring and damaging the lungs. Am J Respir Crit Care Med 80:802–808, 2009. doi: 10.1164/rccm.200812-1845PP. These help narrow antibiotic coverage and exclude opportunistic pathogens. In fact, a peer-reviewed study was conducted to examine the occurrence of non-cystic fibrosis bronchiectasis among U.S. adults in 2013. Bronchiectasis in such patients may have right middle lobe and lingular predominance, and infertility in males or dextrocardia may be present. The right middle lobe is involved most often because its bronchus is small and angulated and has lymph nodes in close proximity. 2. Patients have chronic productive cough with intermittent acute exacerbations. Geographic isolation and the risk for chronic obstructive pulmonary disease-related mortality: a cohort study. 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. In the later stages of CF, infections involve highly resistant strains of certain gram-negative organisms including P. aeruginosa, Burkholderia cepacia, and Stenotrophomonas maltophilia. This is the key difference between bronchitis and bronchiectasis, … 4. Halitosis and abnormal breath sounds, including crackles, rhonchi, and wheezing, are typical physical examination findings. JAMA 309: 1251–1259, 2013. Chest x-ray is usually abnormal and may be diagnostic. 2. Merck & Co., Inc., Kenilworth, NJ, USA is a global healthcare leader working to help the world be well. Bronchitis can be both acute and chronic. Animated Mnemonics (Picmonic): https://www.picmonic.com/viphookup/medicosis/ - With Picmonic, get your life back by studying less and remembering more. ... response (neutrophil proteases) → structural damage → mucous stasis → bacterial colonization → continued chronic inflammation; characterized by p ermanent abnormal dilation of bronchi/bronchioles Chronic bronchitis is thought to be caused by overproduction and hypersecretion of mucus by goblet cells. Bronchiectasis can frequently occur in parallel with more common forms of chronic lung disease including COPD and asthma. As the disease progresses, chronic inflammation and hypoxemia cause neovascularization of the bronchial (not the pulmonary) arteries. Diffuse bronchiectasis occurs when a causative disorder triggers inflammation of small and medium-sized airways, releasing inflammatory mediators from intraluminal neutrophils. Questions. early classifications distinguished chronic bronchitis and emphysema . 1. 1). Prognosis varies widely. verify here. 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. High-resolution computed tomography (CT) is the test of choice for defining the extent of bronchiectasis, and is very sensitive and specific. Significant hemoptysis is usually treated with bronchial artery embolization, but surgical resection may be considered if embolization is ineffective and pulmonary function is adequate. N/A. Chronic rhinosinusitis and nasal polyps may be present, particularly in patients with CF or PCD. There's lots to learn. Chronic obstructive pulmonary disease (COPD) and bronchiectasis are two chronic lung conditions that often co-exist in patients. Dlstinguishing bronchial deformity or dilatation occurs in bronchiectasis, as well as in acute and chronic bronchitis. While you're waiting, use the search box (top right with magnifying glass) and type in bronchiectasis. Common organisms include. Focal bronchiectasis typically develops as a result of untreated pneumonia or obstruction (eg, due to foreign bodies, tumors, postsurgical changes, lymphadenopathy). Initial antibiotic selection for patients with CF is guided by previous sputum culture results (done routinely in all patients with CF). 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. 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. Chronic Bronchitis ... Bronchiectasis. Furthermore, definitions for bronchiectasis given by the clinician, the roentgenologist, and the pathologist may differ greatly. However, most of these measures have had mixed results in limited trials in patients with and without CF. In traction bronchiectasis, pulmonary fibrosis pulls or distorts airways in ways that simulate bronchiectasis on imaging. For patients with cystic fibrosis: Antibiotics and inhaled bronchodilators as well as comprehensive support, and dietary supplementation. Hill AT, Haworth CS, Aliberti S, et al: Pulmonary exacerbation in adults with bronchiectasis: A consensus definition for clinical research. 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 Chronic Bronchitis Emphysema ... - Chronic Bronchitis E 3/28/2013 42 views 2.7 (3) Topic COMMENTS (6) Please login to add comment. Focal bronchiectasis usually occurs when a large airway becomes obstructed. In the same class as COPD and emphysema, bronchiectasis is a chronic obstructive lung condition that leads to pulmonary inflammation and infection. The increasing availability and use of c-HRCT has shown that up to 50% of patients with severe COPD will have co-existent bronchiectasis. "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. 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. Both can cause hemoptysis. This site complies with the HONcode standard for trustworthy health information:   Chronic obstructive pulmonary disease and bronchiectasis are different but related diseases that occur separately, but can coexist, wrote Drs. The degree of testing depends on the severity of the clinical presentation. Bronchitis can be caused by smoking and from viral infections such as those caused by influenza A or B, parainfluenza or coronavirus. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. Digital clubbing is uncommon but may be present. The inflammation of the bronchial walls is known as bronchitis. 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.. ↓ of function of cartilage/elastin in conducting airways, ↑ rate of respiratory infection due to mucus milleu, primary ciliary dyskinesia (Kartagener syndrome), genetic disease resulting in cilia without dyein arm, allergic bronchopulmonary aspergillosis (ABPA), airway clearance with nebulization (saline and hypertonic saline), postural drainage, percussion, and positive expiratory pressure device, azithromycin has been shown to decrease exacerbation rates, localized disease can be treated with lobectomy or segmentectomy, rare other than CF but could be considered if severe, Diffusion-Limited and Perfusion-Limited Gas Exchange, Diffusion-Limited and Perfusion-Limited Oxygen Transport, Acute Respiratory Distress Syndrome (ARDS), Robust inflammatory response (neutrophil proteases). Treatment of underlying disorders is important whenever possible. 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. The link you have selected will take you to a third-party website. 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. Low-grade fever and constitutional symptoms (eg, fatigue, malaise) may also be present. 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. But with proper care and treatment, you can manage it. The inflammatory mediators destroy elastin, cartilage, and muscle in larger airways, resulting in irreversible bronchodilation. Cancel Save. The term is useless for both communication and antibiotic decision. 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. The trusted provider of medical information since 1899. As for all patients with chronic pulmonary disease, recommendations include the following: Pneumococcal vaccination with both 13-valent conjugate (PCV13) and polysaccharide vaccination (PPSV23). Chronic macrolide therapy reduces acute exacerbations in patients with bronchiectasis, and can slow the decline in lung function in patients with CF (3–5). of images. N/A. Airway clearance techniques are used to reduce chronic cough in patients with significant sputum production and mucous plugging and to reduce symptoms during exacerbations. Pulmonary function tests for baseline evaluation and monitoring disease progression, Sputum culture for bacteria and mycobacteria to determine colonizing organisms. Yet, the chances of concurrent COPD and bronchiectasis are slim: while COPD is the third leadin… Appropriate diagnostic approaches include a complete history and physical examination, sputum cultures, and pulmonary function tests [forced expiratory volume in 1 … Bronchiectasis can be caused by bacterial infections such as pneumonia, and chronic infections such as cystic fibrosis, allergic bronchopulmonary aspergillosus, and HIV. Polverino E, Gemine PC, McDonnell MJ, et al: European Respiratory Society guidelines for the management of adult bronchiectasis. Symptoms characteristically begin insidiously and gradually worsen over years, accompanied by episodes of acute exacerbation. Lean body mass commonly decreases, possibly due to inflammation and cytokine excess and, in patients with CF, malabsorption. Bronchiectasis is a chronic condition where the walls of the bronchi are thickened from inflammation and infection in the bronchi. The evidence supporting their use and benefit is strongest in the CF population. Patients with cystic fibrosis may receive nebulized treatments, including a mucolytic (rhDNase) and hypertonic (7%) saline, to help reduce sputum viscosity and enhance airway clearance.
