![]() ![]() Epithelial damage due to COPD-associated chronic inflammation and loss of lung elasticity cause difficulties in clearing the airway of mucus. The mucus is mainly produced by goblet cells, which act as the first line of defense for the respiratory tract and interact with the immune system. In addition to emphysema, patients with COPD often experience chronic bronchitis consequent to mucus accumulation in the lung. These changes keep the lungs from remaining open during expiration, limit airflow in the airway, reduce expiratory output, and cause dyspnea, a common symptom of difficult breathing. Emphysema, also known as parenchymal destruction, is characterized by abnormal permanent enlargement of air spaces distal to the terminal bronchiole, resulting in a loss of alveolar attachment and a decrease in the elasticity of the lungs. Chronic bronchitis is the inflammation of bronchial tubes leading to the narrowing of the small airways, which carry air in and out the air sacs (alveoli) in the lungs. ![]() The two most common clinical conditions of COPD include chronic bronchitis and emphysema. Although COPD prevalence continues to rise, strategies for prevention, treatment, and management of the disease are limited. ![]() Guidance Document - RRT Entry to LicensureĬhronic obstructive pulmonary disease (COPD) is listed as the third leading cause of death globally.1 COPD is characterized by limitations in expiratory airflow, emphysematous destruction of the lungs, chronic bronchitis, and chronic inflammation within the lung tissue.Coding, Billing and Reimbursement Issues.Early Professional Membership for Students.“In summary, comparative data on trials of the new LAMA/ LABA FDC inhalers against one of the ICS/LABA combination inhalers (fluticasone plus salmeterol) are now available, and the results significantly favor the LAMA/ LABA inhalers in terms of efficacy (improvements in FEV1), patient-reported outcomes (TDI, mMRC), and quality of life measures (SGRQ),” concluded the study. Therefore, LAMA/LABA FDC is a more cost-effective option because of the reduction in long term adverse effects, including exacerbations, and the unpredictability of how much they can cost a COPD patient over time. LAMA/LABA inhalers decrease the risk of pneumonia by 33% to 67%, according to the analysis. “The new LAMA/LABA FDCs are now widely available and are a welcome addition to the options available for maintenance therapy in COPD.” “Given the significant adverse effects and increased incidence of pneumonia with long-term use of ICS, a favorable efficacy and safety profile of new LAMA/LABA FDCs versus ICS/LABA in COPD patients is very encouraging,” noted the researchers. Pnemonia rates, forced expiratory volume in 1 second (FEV 1), and other adverse events were also considered, and significant improvements were established in favor of the LAMA/LABA inhaler for COPD treatment. Annual exacerbation rates among participants treated with indacaterol/glycopyrronium, one type of LAMA/LABA inhaler, were lower than the fluticasone/salmeterol group in a study. The analysis found significant decreases in exacerbation rates in the long duration trials with the dual bronchodilator. Long-term use of ICS has demonstrated increased incidence of pneumonia and other adverse effects. The new long-acting muscarinic antagonist and long-acting beta-agonist (LAMA/LABA) fixed dose combination (FDC) inhaler may be a better option than inhaled corticosteroids (ICS) for long-term use.Ī new review published by Dove Press analyzes data from previous studies that draw comparisons between new therapies and ICS/LABA. As more long-term therapies for chronic obstructive pulmonary disease (COPD) are being developed, the results and efficacy of different therapies vary. ![]()
