J Antimicrob Chemother 2006;57:741-746, 38. Martinez FJ, Curtis JL, Albert R. Role of macrolide therapy in chronic obstructive pulmonary disease. Participants were randomly assigned, in a 1:1 ratio, to receive azithromycin, at a dose of 250 mg orally, or an identical-appearing placebo, once daily. These differences remained significant after adjustment with the use of Cox regression for differences in sex, FEV1, age, smoking status, and study center. Seemungal TA, Donaldson GC, Paul EA, Bestall JC, Jeffries DJ, Wedzicha JA. No significant differences were observed in the frequency of serious adverse events or of adverse events leading to discontinuation of the study drug, but an audiogram-confirmed hearing decrement occurred in 142 of the participants receiving azithromycin (25%), as compared with 110 of those receiving placebo (20%) (P=0.04). The frequency of exacerbations was 1.48 exacerbations per patient-year in the azithromycin group, as compared with 1.83 per patient-year in the placebo group (P=0.01), and the hazard ratio for having an acute exacerbation of COPD per patient-year in the azithromycin group was 0.73 (95% CI, 0.63 to 0.84; P<0.001). A Cox proportional-hazards model was used to adjust for differences in prespecified, prerandomization factors that might predict the risk of acute exacerbations of COPD. Acute exacerbations adversely affect patients with chronic obstructive pulmonary disease (COPD). What you experience during an acute COPD exacerbation is different from your typical COPD symptoms. Blasi F, Bonardi D, Aliberti S, et al. You may experience COPD symptomslike fatigue, wheezing, and exercise intolerance on a regular basis—or even every day. The median time to the first acute exacerbation among the participants who received erythromycin was 271 days, similar to the 266 days we found among the participants in our study who received azithromycin. Our results should be applied only to patients with COPD who either require supplemental oxygen or have had acute exacerbations and who do not have resting tachycardia or prolongation of the QTc interval, are not taking medications associated with QTc prolongation, and do not have hearing abnormalities that place them below the 95th percentile of patients of similar age. Because the researchers did not reach their goal of 500 participants, the trial was underpowered to demonstrate statistical significance of its primary endpoint: time to treatment failure. We chose a 250-mg dose of azithromycin because we thought that it was high enough to limit the possibility that a negative result might occur because of insufficient dosing. Information, resources, and support needed to approach rotations - and life as a resident. The effect of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage (which ranges from stage I COPD, indicating mild disease, to stage IV COPD, indicating very severe disease) on the rate of acute exacerbations of COPD and on frequency of hospitalizations is presented in Section B in the Supplementary Appendix, available at NEJM.org. In the Macrolide trial, treatment with azithromycin significantly reduced exacerbation frequency in high-risk patients with COPD compared with placebo (1.48 vs 1.83 exacerbations per patient year, p=0.01) and increased the time to first exacerbation. Narrow antibiotics seem to be as effective as broader antibiotics, but may cause less Clostridioides difficile. Thorax 2005;60:925-931, 12. The primary analysis was based on a log-rank test of the difference between the two treatment groups in the time to the first exacerbation, with no adjustments for baseline covariates. The costs of exacerbations in chronic obstructive pulmonary disease (COPD). Among patients hospitalized for an acute exacerbation of chronic obstructive pulmonary disease (COPD), 49% of those who received adjunct therapy with azithromycin had COPD treatment failure by three months versus 60% of those who did not. Although this mean change did not exceed the minimal clinically important difference of at least 4 units, more participants in the azithromycin group than in the placebo group had a decrease of at least 4 units in their SGRQ score (43% vs. 36%, P=0.03). If … When we began the study, we obtained both expectorated sputum samples and nasopharyngeal swabs because we knew that some patients would not be able to produce sputum. Subsequent audiograms showed that hearing improved to the baseline level in 21 of the 61 participants (34%) who discontinued azithromycin and in 6 of the 19 (32%) who did not, as well as in 14 of the 37 participants (38%) who discontinued placebo and in 2 of the 8 (25%) who did not. The NHS protocol for management of COPD exacerbations in primary care states that bronchodilators and corticosteroids are the mainstay of exacerbation treatment. Among subjects at increased risk for acute exacerbations of COPD who received azithromycin, at a dose of 250 mg once daily, for 1 year in addition to their usual care, the frequency of acute exacerbations was decreased. Azithromycin may reduce treatment failure for acute COPD exacerbations. The authorized source of trusted medical research and education for the Chinese-language medical community. FEV1 denotes forced expiratory volume in 1 second, and FVC forced vital capacity. This decrease was accompanied by a decrease in the incidence of colonization with selected respiratory pathogens and improved quality of life, but also an increase in the incidence of colonization with macrolide-resistant organisms and an excess rate of hearing decrements of approximately 5%. 31. Respir Med 2002;96:700-708, 3. Azithromycin for Prevention of COPD Exacerbations. Azithromycin maintenance treatment in patients with frequent exacerbations of chronic obstructive pulmonary disease … JAMA 2010;303:1707-1715, 39. The data were analyzed by the second author, who is a statistician, together with the first author. A small but significant between-group difference was observed in the mean age-adjusted hearing thresholds for the four sound frequencies from enrollment to month 3, with patients in the azithromycin group having more pronounced hearing decrements (see Section F in the Supplementary Appendix). Cultures from 56% of the participants in the azithromycin group and 59% in the placebo group who had selected respiratory pathogens cultured from their nasopharyngeal swabs at the time of enrollment were available for susceptibility testing (P=0.68); the remaining cultures were not tested because of protocol errors. The complete protocol, including the statistical analysis plan, is available with the full text of this article at NEJM.org. Prevention of COPD exacerbations is not the only reason, or even the main reason, to prescribe or use a COPD treatment.

The frequency of acute exacerbations was lower among participants receiving azithromycin than among those receiving placebo regardless of the rate of acute exacerbations per patient-year (P=0.008 by both Poisson and negative binomial models) (Figure 3). The primary outcome was the time to the first acute exacerbation of COPD, with acute exacerbation of COPD defined as “a complex of respiratory symptoms (increased or new onset) of more than one of the following: cough, sputum, wheezing, dyspnea, or chest tightness with a duration of at least 3 days requiring treatment with antibiotics or systemic steroids.”19 At each clinic visit and telephone contact, study personnel determined whether an acute exacerbation of COPD had occurred in the previous month. The prevalence of resistance to macrolides was 52% and 57% in the two groups, respectively (P=0.64). The date of each acute exacerbation was taken as the date treatment was prescribed.

Prepare to become a physician, build your knowledge, lead a health care organization, and advance your career with NEJM Group information and services. The total SGRQ scores recorded at 1 year decreased a mean (±SD) of 2.8±12.1 units in the azithromycin group, as compared with a mean of 0.6±11.4 units in the placebo group (P=0.006) (see Section C in the Supplementary Appendix for individual scale scores). 2011;365:689-98). Azithromycin is an antibiotic that has previously been proven effective in preventing exacerbations in at-risk, stable … Am J Respir Crit Care Med 2008;178:1139-1147, 29. The minimal clinically important difference in the SGRQ score was considered to be −4 units, and the percentage of patients with a change of at least 4 units from the time of enrollment was a prespecified end point.34 Deep nasopharyngeal swabs were obtained at the time of enrollment and every 3 months thereafter, and selected respiratory pathogens were assessed for resistance to macrolides. The rates of acute exacerbations of COPD differed according to center, but the hazard ratio for the time to the first acute exacerbation of COPD, stratified according center, was 0.71 (95% CI, 0.61 to 0.83; P<0.001). Brusasco V, Hodder R, Miravitlles M, Korducki L, Towse L, Kesten S. Health outcomes following treatment for six months with once daily tiotropium compared with twice daily salmeterol in patients with COPD. Mahler DA, Donohue JF, Barbee RA, et al. Sin DD, McAlister FA, Man SFP, Anthonisen NR. The patients were randomly assigned to treatment with azithromycin (n = 147) or placebo (n = 154) within 48 hours of admission. The American Thoracic Society improves global health by advancing research, patient care, and public health in pulmonary disease, critical illness, and sleep disorders. The median time to the first acute exacerbation of COPD was 266 days (95% confidence interval [CI], 227 to 313) in participants receiving azithromycin, as compared with 174 days (95% CI, 143 to 215) in participants receiving placebo (P<0.001). Donaldson GC, Seemungal TA, Bhowmik A, Wedzicha JA. 25 Seven small studies that tested whether macrolides decrease the frequency of acute exacerbations of COPD reported conflicting results.26-32 Accordingly, we conducted a large, randomized trial to test the hypothesis that azithromycin decreases the frequency of acute exacerbations of COPD when added to the usual care of these patients. Pulm Pharmacol Ther 2010;3:200-207, 32. Given the deleterious effects of acute exacerbations of COPD with respect to the risk of death, quality of life, loss of lung function, and cost of care, adding azithromycin to the treatment regimen of patients who have had an acute exacerbation of COPD within the previous year or who require supplemental oxygen is a valuable option; however, the patients should be screened for the presence of QTc prolongation and the risk of QTc prolongation and their hearing should be monitored. 36. document.write(new Date().getFullYear()) The rate of 1-year follow-up was 89% in the azithromycin group and 90% in the placebo group. ), 34.

Peer-reviewed journal featuring in-depth articles to accelerate the transformation of health care delivery. None of the previous studies of the effect of macrolides on acute exacerbations of COPD either assessed or reported hearing problems as a complication.26-32 We found that more participants receiving azithromycin met the criteria for development of a hearing decrement than did those receiving placebo, but the improvements in hearing that occurred on repeat testing, regardless of whether the study drug was discontinued, suggest that our criteria were too stringent and that the incidence of hearing decrements was overestimated in both groups. Conclusions: This post-hoc analysis of the BACE trial shows that azithromycin initiated at the onset of an infectious COPD exacerbation requiring hospitalization reduces the incidence rate of TF within 3 m by preventing hospital readmissions. — both in Ann Arbor; the Division of Pulmonary and Critical Care Medicine, Department of Medicine, and the Cardiovascular Research Institute, University of California, San Francisco, San Francisco (S.C.L., P.G.W.

Antibiotic Guidance for Treatment of Acute Exacerbations of COPD (AECOPD) in Adults Antibiotics are not recommended for most patients with AECOPD. Seven previous studies have evaluated whether macrolide antibiotics decrease the risk of acute exacerbations of COPD. Combined salmeterol and fluticasone in the treatment of chronic obstructive pulmonary disease: a randomised controlled trial. Objectives: We investigated whether a 3-month intervention with low-dose azithromycin could decrease treatment failure (TF) when initiated at hospital admission and added to standard care. Rates of Acute Exacerbations of Chronic Obstructive Pulmonary Disease per Person-Year, According to Study Group. The characteristics of the participants at the time of enrollment are summarized in Table 1. This article (10.1056/NEJMoa1104623) was updated on April 5, 2012, at NEJM.org. before starting prophylactic antibiotic therapy in a person with COPD, think about whether respiratory specialist input is needed. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. The effect of azithromycin on the secondary outcomes is summarized in. In summary, we found that adding azithromycin, at a dose of 250 mg daily, for 1 year to the usual treatment of patients who have an increased risk of acute exacerbations of COPD but no hearing impairment, resting tachycardia, or apparent risk of QTc prolongation decreased the frequency of acute exacerbations of COPD and the incidence of colonization with selected respiratory pathogens and improved quality of life but increased the incidence of colonization with macrolide-resistant organisms and decreased hearing in a small percentage of participants.

JAMA 2003;290:2301-2312, 25. Accordingly, the data were analyzed with the use of group sequential testing36 that allowed “spending” a little of the alpha at each interim analysis such that, at the end of the study, the total type I error did not exceed 0.05. Respir Med 2005;99:208-215, 27. The study found that the rates of treatment failure were 49 percent for those in the azithromycin group vs. 60 percent in the placebo arm. Secondary outcomes included quality of life, nasopharyngeal colonization with selected respiratory pathogens (i.e., Staphylococcus aureus, Streptococcus pneumoniae, haemophilus species, and moraxella species), and adherence to taking the study drug as prescribed. He ZY, Ou LM, Zhang JQ, et al. Azithromycin is generally first-line, if the patient hasn't been exposed to it recently (don't worry, it doesn't cause Torsade de Pointes).

Although the study could not prove statistical significance of its primary endpoint, “a positive message of the trial is that our strategy reduced hospital time, days in the ICU and recurrent exacerbations in the most severe COPD group,” Dr. Janssens said, adding that a large phase 4 study with hospital readmission as the primary endpoint would be necessary before broad implementation of the current study’s findings. The researchers defined treatment failure as the need to intensify treatment with systemic corticosteroids and/or antibiotics, transfer the patient to the intensive care unit or readmit the patient to the hospital after discharge, and death from any cause.

The costs of treating COPD in the United States. However, Dr. Janssens explained that this strategy is not commonly used because it was associated with a variety of adverse events, not least of which was … No other potential conflict of interest relevant to this article was reported. Nasopharyngeal swabs were obtained at 85% and 84% of the clinic visits attended by participants in the azithromycin group and placebo group, respectively. This review did not examine the other benefits of COPD medications, like improved breathing or increased exercise capacity.
