Erdosteine is a recently developed mucoactive medication with antioxidant and anti-inflammatory properties that modify bacterial adhesiveness.70 The RESTORE study, a prospective randomized, double-blind, placebo-controlled study of patients with GOLD stage II and III COPD, showed that patients who received erdosteine 300 mg twice daily added to usual treatment reduced exacerbation rates by 19.4% (0.91 versus 1.13 exacerbations/patient/year, p=0.01), mostly due to a reduction of mild exacerbations. However, in a post-hoc analysis, roflumilast significantly reduced the rate of moderate and severe exacerbations in participants with greater than 3 exacerbations per year and/or one or more hospitalizations in the prior year.83, In all studies, withdrawal from the study due to adverse events was more common in those receiving roflumilast. Respir Med. 1989;226(1):25-32. Conditional Low This recommendation is based on the higher value of the clinical benefits from ICS in some patients with asthmatic cough (or airway eosinophilic inflammation) and lower value of adverse events. Request PDF | Canine Chronic Bronchitis | Chronic bronchitis is a syndrome defined by cough on most days for at least 2 months where no specific cause can be identified. Increasing prevalence of asthma but not of chronic bronchitis in Finland? Chronic bronchitis is a progressive lung disease. doi: https://doi.org/10.1002/14651858.CD002309.pub5. The rate of change in lung function did not differ between groups, but the absolute difference in lung function between groups favored the hypertonic saline group. Variations in the prevalence across countries of chronic bronchitis and smoking habits in young adults. Based on these studies, the GOLD 2018 report recommended considering the addition of roflumilast in patients with exacerbations and severe airflow obstruction and CB who are not controlled on an ICS/LABA with or without a LAMA.85, Short-acting beta2 agonists (SABAs) promote mucus clearance by increasing airway luminal diameter and ciliary beat frequency.62 The regular use of SABA in stable COPD is associated with improvements in lung function and breathlessness.86 Short-acting muscarinic antagonists (SAMAs) such as ipratropium bromide decrease intracellular concentration of cyclic guanosine monophosphate (cGMP), resulting in decreased contractility of smooth muscle in the lung, inhibiting bronchoconstriction and mucus secretion.87 Both LABAs and LAMAs improve lung function, dyspnea, and health status and reduce exacerbation rates in patients with COPD.85 Studies have shown an increased ciliary beat frequency and improved mucociliary clearance with LABAs, and decreased cough with LAMAs. A great need for more information regarding therapy is also apparent. 2015;24(137):451-461. doi: https://doi.org/10.1183/16000617.00002215, 69. Robinson M, Regnis JA, Bailey DL, King M, Bautovich GJ, Bye PTP. Systematic review with meta-analysis of the epidemiological evidence relating smoking to COPD, chronic bronchitis and emphysema. In the COPD Genetic Epidemiology study (COPDGene®), use of the SGRQ definition identified 50.9% more individuals compared to the classic definition (1801 versus 1179 individuals out of 4572, respectively).15 Using the classic definition as the gold standard, the SGRQ definition had a sensitivity of 0.87 and specificity of 0.77.15 Similar results were found in the Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS).16. The association between CMH and death from obstructive lung disease increased as lung function worsened.55 A Finnish study followed approximately 1700 patients for up to 40 years. 2011;365(8):689-698. doi: https://doi.org/10.1056/NEJMoa1104623, 77. 2017;123:87-93. doi: https://doi.org/10.1016/j.rmed.2016.12.018, 54. Patients with severe CB had a shorter time to hospitalization and worse health-related QoL.54 Another study by Kim et al compared patients with COPD GOLD stage II-IV with (n=290) and without CB (n=771) and showed that those with CB were younger, had a greater pack-year smoking history, were more likely to be current smokers and had higher rates of exacerbations.8 In a multicenter French study, patients with COPD and CB (n=321) had greater numbers of exacerbations than patients without CB (n=112).17. All age groups are affected but over 20 per cent of adult males and about 10 per cent of adult females appear to have the symptoms of chronic productive cough.

The non-obstructed CB patients were younger, had a lower pack-year history of smoking, and had a worse QoL compared to those with COPD and no CB.50, CB is also a known risk factor for development of airflow obstruction. Electronic cigarette use and respiratory symptoms in adolescents. The serious consequences of the disease are usually noted after the age of 40. Two double-blind, multicenter trials, one using salmeterol (n=466) and the other using tiotropium (n=371) in both arms, randomly assigned patients with moderate-to-severe COPD to roflumilast 500 μg or placebo once daily for 24 weeks. Given the symptoms that Marissa is presenting with, differential diagnoses include: asthma, allergic reaction, infection (bronchitis, bronchiolitis, pneumonia, upper respiratory infection, etc. The clinical phenotype identified by the SGRQ definition is nearly identical to the one identified by the classic definition in the COPDGene® study. 11/23/2019 Understanding Chronic Bronchitis: What Is It? Am Rev Respir Dis. Since chronic bronchitis is defined on clinical grounds, patients without spirometric values, but with ATS criteria of chronic bronchitis, were included in the study. This can block the airflow through the lungs and may damage the lungs. Pharmacologic therapy for CB is directed towards 3 major goals: relieving symptoms during stable disease (mucoactive agents, beta-agonists, muscarinic antagonists), reducing loss of lung function (smoking cessation), preventing exacerbations (mucoactive agents, macrolides, phosphodiesterase-4 [PDE-4 inhibitors]) and treating exacerbations (antibiotics, glucocorticoids) when they occur (Table 6). Chronic productive cough is associated with death in smokers with early COPD. With chronic bronchitis, the airways (bronchial tubes) become swollen and inflamed and produce large amounts of mucus. Tockman MS, Comstock GW. The data collected on 51 patients showed no significant difference in SGRQ or secondary outcomes.67 Finally, a meta-analysis on 13 studies including 4155 COPD patients showed that those treated with NAC had significantly fewer exacerbations of CB or COPD (RR 0.75, 95% CI 0.66-0.84; p<0.01). 1980;20(4):237-266. doi: https://doi.org/10.2165/00003495-198020040-00001, 88. with chronic bronchitis may have other concurrent respiratory abnormalities (e .g.

Section: Chronic bronchitis (CB) is a common but variable phenomenon in chronic obstructive pulmonary disease (COPD). 75. CB was associated with increased all-cause mortality (HR 1.23) and mortality from respiratory causes, cardiovascular diseases and cancer. Although bronchitis may start out as an acute condition, when it recurs repeatedly over 2 years, the diagnosis changes to chronic bronchitis. Mucolytic agents for chronic bronchitis or chronic obstructive pulmonary disease. Int J Chron Obstruct Pulmon Dis. There was, however, no significant effect of azithromycin in those that were currently smoking, probably secondary to the upregulation of mucin secretion (MUC5AC) and down regulation of the respiratory immune function of active smoking which counteracts the down regulation of mucin and reduction of the bacterial load by azithromycin.77, Two major determinants of effective mucociliary clearance are directly regulated by cyclic adenosine monophosphate (cAMP): ciliary beat frequency and cystic fibrosis transmembrane receptor (CFTR) activity.78,79 PDEs break down cAMP, thereby reducing intracellular cAMP concentrations. 2010;182(5):598-604. doi: https://doi.org/10.1164/rccm.200912-1843CC, 2.

There are two main types, acute and chronic. Phenotypic and genetic heterogeneity among subjects with mild airflow obstruction in COPDGene®. Persistent and newly developed chronic bronchitis are associated with worse outcomes in chronic obstructive pulmonary disease. However, hearing decrements were more common (25% versus 20%, p = 0.04), and the incidence of macrolide resistance was significantly higher (81% versus 41%, p<0.001) in those treated with azithromycin.76 A post hoc analysis of the MACRO trial was done to identify the types of exacerbations and subgroups most likely to benefit from azithromycin therapy.

Instead, I tell them about some simple treatments they can do at home. Longitudinal data on a random cohort of nearly 4000 patients followed for 12 years showed that the presence of cough and phlegm at the initial visit was associated with a more rapid decline of lung function after adjustment for height, age, and cigarette smoking.51 The Copenhagen City Heart Study (n=9435) followed patients with spirometry every 5 years and showed that CMH was significantly associated with forced expiratory volume in 1 second (FEV1) decline after adjusting for age, height, weight change and smoking.5 An international cohort of 5002 patients with normal lung function at baseline followed for 12 years showed that patients with chronic cough or phlegm had nearly a 2-fold increased risk of developing airflow obstruction.30, CB is not only associated with an accelerated lung function decline, but also with an increased risk of COPD exacerbations. 2010;65(3):221-228. doi: https://doi.org/10.1136/thx.2009.124644, 47. Sobradillo V, Miravitlles M, Jiménez CA, et al. Respirology. All patients took inhaled corticosteroids (ICSs) and a long-acting beta2 agonist (LABA) during the study, and a background long-acting muscarinic antagonist (LAMA), tiotropium, was allowed.

In the aforementioned Finnish study, the cumulative incidence of CB was 22% in nonsmokers.6 An analysis of 2 separate cross sectional surveys in 1998/2000 and 2007/2010 showed similar prevalence of CB but an increase in never smokers (7.6% to 9.1%), an overall decrease in current smoking (33.6% to 26.9%) and an increase in allergic rhinitis (19.5% to 24.5%).40, Specific occupational exposure studies (coal and hard-rock miners, tunnel workers, concrete-manufacturers, and non-mining industrial workers) and world-wide community-based studies have demonstrated a link between these exposures, respiratory symptoms and the development of COPD.35 Livestock farming has also been recognized as a risk factor for developing CB. It is common among smokers. Chronic bronchitis (CB) is a common but variable phenomenon in chronic obstructive pulmonary disease (COPD). Acute Bronchitis Self-management options include: Occasionally other treatment options will include: Preventive options to reduce the risk of acute bronchitis reoccurring include: • Quitting smoking Quitting smoking or avoiding second-hand smoke can help to relieve symptoms. Additionally, the SGRQ definition is much simpler to use in clinical practice; patients are asked 2 questions, 1 on cough and 1 on sputum, and are asked to rate them from “not at all,” “only with lung/respiratory infections,” “a few days a month,” “several days a week,” or “almost every day.” The SGRQ definition of CB is both cough and phlegm “almost every day” or “several days a week.” In comparison, the classic definition requires answering multiple questions (6 to 12, see Table 1) on cough, sputum, months per year, and number of years.

However, a secondary analysis of functional residual capacity data showed that NAC reduced hyperinflation, but the mechanism of this finding was not clear.65 The PANTHEON study was a prospective, randomized, placebo-controlled, parallel-group study on patients with moderate-to-severe COPD (n=1006).66 The exacerbation rate was lower (1.16 versus 1.49 exacerbations/patient/year) in patients who were treated with NAC (600 mg twice daily) compared to placebo. It has numerous clinical consequences, including an accelerated decline in lung function, greater risk of the development of airflow obstruction in smokers, a predisposition to lower respiratory tract infection, higher exacerbation frequency, and worse overall mortality.
