First, concomitant treatment with OCS was regulated per protocol and was prescribed in 95% of the patients, in contrast with the two previously mentioned trials [3, 14]; OCS are recommended in all current guidelines as OCS improve lung function and might reduce treatment failure [15]. The second study investigated the use of doxycycline (daily) in addition to roxithromycin (daily) for 12 weeks in COPD. - Full-Length Features Background: Antibiotics do not reduce mortality or short-term treatment non-response in patients receiving treatment for acute exacerbations of COPD in an outpatient setting. No clinical characteristics, particularly not sputum characteristics, can guide antibiotic prescription in patients with mild to severe COPD exacerbations https://bit.ly/3e1JV8o. Register for free and gain unlimited access to: - Clinical News, with personalized daily picks for you An exacerbation was defined as an event characterised by a change in patients' baseline dyspnoea, cough or sputum beyond day-to-day variability, sufficient to warrant a change in management other than optimising bronchodilator therapy [ 1, 5 ]. The antibiotics investigated were azithromycin, erythromycin, clarithromycin, roxithromycin, doxycycline and moxifloxacin ... We found that, with the use of antibiotics, the number of participants who developed an exacerbation reduced markedly. Type 3: one Anthonisen criterion present. Methods We conducted a retrospective analysis of antibiotic prescriptions for non-pneumonic exacerbations of COPD … This large cohort study evaluated doxycycline effects on AECOPD in both short-term and long-term for outpatients based on real-world data and highlights the possible influence of age on short-term effects of doxycycline. Two randomised trials reported that sputum purulence is associated with treatment failure if not treated with antibiotics [3, 14], but this finding was not confirmed in our trial: failure rates did not differ in type 1 versus type 2/3 exacerbations and exacerbations with or without sputum purulence treated with or without antibiotics. Prophylactic antibiotics may be used to reduce the overall rate of COPD exacerbations and delay their onset. Zhang H-L, Tan M, Qiu A-M, Tao Z, Wang C-H. Don’t miss out on today’s top content on Pulmonology Advisor. An analysis in which we partitioned our data into tertiles to enhance contrast between the lowest and the highest tertiles also did not demonstrate subgroup effects. Previous research suggests that these anti-inflammatory properties may be beneficial in the treatment of COPD. Jan M. Prins, MD, division of infectious diseases at the Academic Medical Centre in Amsterdam, The Netherlands, and colleagues conducted a randomized controlled trial of 887 patients with mild to moderate COPD exacerbations from outpatient clinics at 9 teaching hospitals and 3 primary care centers in The Netherlands. Dosage is 0.25 to 0.5 mg by nebulizer or 2 to 4 inhalations (17 to 18 mcg of drug delivered per puff) by metered-dose inhaler every 4 to 6 hours. 301 patients were included in the trial, 150 in the doxycycline group and 151 in the placebo group. These findings do not support prescription of antibiotics for COPD exacerbations in an outpatient setting. Antibiotics may be prescribed in some cases of chronic obstructive pulmonary disease (COPD) during exacerbations (flare-ups) if there are signs of infection. We assessed whether taking daily doxycycline over one year changes COPD exacerbation rate. Trial design, participants and procedures have been described previously [9]. here. However, they advised caution in using antibiotics to treat exacerbations of COPD, as adverse effects occur with all of these drugs. Although in the Netherlands doxycycline is a first-choice antibiotic for COPD exacerbation treatment since resistance of common pathogens causing COPD exacerbations is rare and the posology is convenient, it is possible to speculate that different antibiotics may yield different long-term effect on COPD exacerbations. X.2.2.4 Combined systemic corticosteroids and antibiotics for treatment of exacerbation A randomised placebo controlled trial (Daniels 2010) has provided evidence to support the traditional practice of treating exacerbations with a combination of systemic corticosteroids and antibiotics. Goroll AH. In short, we recruited a cohort of patients with COPD from outpatient clinics of nine teaching hospitals and three primary care centres in the Netherlands. However, we did not find clinical characteristics, in particular not sputum characteristics, in patients with mild to severe COPD with an exacerbation without fever that identify those who benefit from antibiotic treatment. In addition, a procalcitonin-guided antibiotic strategy has been associated with fewer antibiotic prescriptions [8]. There were no deaths in either group. These findings do not support prescription of antibiotics for COPD exacerbations This review assesses the potential benefit of prophylactic, long-term, and low-dose antibiotic therapy … In patients with mild-to-severe COPD receiving treatment for an exacerbation in an outpatient setting, the antibiotic doxycycline added to the oral corticosteroid prednisolone did not prolong time to next exacerbation compared with prednisolone alone. The first study included three groups of COPD patients taking either moxifloxacin (daily for 5 days every 4 weeks), doxycycline (daily for 13 weeks) or azithromycin (3 times per week for 13 weeks). Subgroups were based on clinical variables available at baseline or during exacerbation, including exacerbation characteristics, spirometry data, medical history, inhalation medication and health-related quality of life. Additional, related documents, including the study protocol and statistical analysis plan, will be available. As these tools are not always available, additional research is needed to identify those outpatients that benefit from antibiotic therapy. In cases of an exacerbation, patients were randomly assigned to receive doxycycline or a placebo. Data will be shared with researchers who provide a methodologically sound proposal, to achieve aims in the approved proposal. The aim of this study was to investigate if the antibiotic doxycycline added to the oral corticosteroid prednisolone prolongs time to next exacerbation in patients with COPD receiving treatment for an exacerbation in the outpatient setting. Second, fever was an exclusion criterion. Mild exacerbation (no respiratory failure+, FEV 1 >50% predicted, < 3 exacerbations/year) o 1st line: Doxycycline 100 mg PO BID OR Cefuroxime 500 mg PO BID o 2nd line: Azithromycin 500 mg PO daily* Moderate exacerbation (non-life-threatening respiratory failure+, FEV 1 36-50%, ≥ 3 exacerbations/year, ≥65 years of age) An exacerbation was defined as an event characterised by a change in patients’ baseline dyspnoea, cough or sputum beyond day-to-day variability, sufficient to warrant a change in management other than optimising bronchodilator therapy [1, 5]. We hope you’re enjoying the latest clinical news, full-length features, case studies, and more. The distribution of the number of days until discontinuation by bacterial coinfection status is reflected in Figure Figure1. Subgroup analyses for patients who had treatment failure at day 21. We found no other subgroup effects (figure 1). Vogelmeier CF, Criner GJ, Martínez FJ, et al. The aim of this study was to investigate if the antibiotic doxycycline added to the oral corticosteroid prednisolone prolongs time to next exacerbation in patients with COPD receiving treatment for an exacerbation in the outpatient setting. Population prescribing habits and their consequences have not been well-described. Groningen. Enjoying our content? Protected by copyright. “[T]hese characteristics may explain why doxycycline did not prolong the time to relapse. Age may affect antibiotic effectiveness, but real-world evidence is lacking. We used a significance level of 0.05; therefore, given the number of comparisons, at least one interaction test is expected to be statistically significant based on chance alone [11]. - Conference Coverage Discussion: The prescription of multiple antibiotic courses for COPD exacerbations was relatively common-one in twelve patients receiving antibiotics for LRTI had a further course within 2 weeks. Conflict of interest: G. ter Riet has nothing to disclose. However, no reductions were seen in this population in the long term (approximately 12 months) or in … For all subgroups, stratum-specific odds ratios with 95% confidence intervals and tests for interaction were calculated.
