copd exacerbation treatment antibiotics

In fact, the recognition of M. catarrhalis as an important cause of COPD exacerbations came from several reports of patients failing treatment with a β-lactam antibiotic who were infected with a β-lactamase–producing strain of this pathogen . An algorithm used by the current author that incorporates the Anthonisen criteria and also emphasises the importance of purulent sputum is shown in figure 1. The MOSAIC study (a multicentre, multinational, prospective, randomised, double-blind study to compare the effectiveness of Moxifloxacin Oral tablets to Standard oral antibiotic regimen given as first-line therapy in out-patients with Acute Infective exacerbations of Chronic bronchitis) attempted to bring all these concepts together, and by strict entry criteria achieve a pure smoking-related COPD study population [45]. This was the first study to suggest that LABC in the stable condition might be a stimulus for chronic inflammation, and the result has been confirmed recently in a similar designed study using sputum [24]. The same findings were seen with the bactericidal assay, and only 12% of heterologous strains of H. influenzae were killed. The general view has been that it is not, although the current author would still argue the case for a placebo-controlled trial carried out under controlled conditions. Neutrophil elastase-positive cells were seen in the epithelium and sub-epithelial tissues, co-locating bacteria with inflammatory cells, but this study falls short of proving that the bacteria were the cause of the inflammation. © NICE 2018. Co-administer Corticosteroids. Five trials showed no reduction in the frequency of exacerbations whereas four did show this benefit. Macrolide Antibiotics Treat COPD Exacerbations Empiric antibiotics with macrolides, beta-lactams, or doxycycline have long been part of the established therapies for COPD exacerbations (since well before the advent of the modern clinical trial era). Background: Many patients with an exacerbation of chronic obstructive pulmonary disease (COPD) are treated with antibiotics. Therefore, it would be wrong to assume that a colonising strain is benign and not making a contribution to chronic airway inflammation in the stable state. Core principles of asthma management, inhaler selection and use, and referral guidance, from the All Wales Medicines Strategy Group. However, when all patients were considered and treatment failures were eliminated from the analysis, the benefit from antibiotics on speed of recovery was only 0.9 days, a nonsignificant difference. The bacteriological and short-term outcomes of the GLOBE study were the same as the TACTIC study, but the percentage of patients who did not have a further exacerbation during the 26-week period was significantly (p<0.05) greater after treatment with the quinolone antibiotic. [B] If a person is receiving antibiotic prophylaxis, treatment should be with an antibiotic from a different class. X2.2.3 Antibiotics for treatment of exacerbations Exacerbations with clinical features of infection (increased volume and change in colour of sputum and/or fever) benefit from antibiotic therapy [evidence level II, strong recommendation] Bacterial infection may have either a primary or secondary role in about 50% of exacerbations of COPD (Macfarlane 1993, Wilson 1998, Miravitlles 1999, Patel 2002). LABC is a dynamic process, so that strains may be carried for variable periods of time before being lost and replaced by others. Most have leaned heavily on the study by Anthonisen et al. Current cigarette smoking predisposes to LABC, but studies have disagreed whether airflow obstruction is a predisposing factor. Bacteriological and clinical outcomes obtained during a trial of moxifloxacinversus clarithromycin in acute exacerbations of chronic bronchitis. The classical studies of Fletcher et al. This allowed them to study changes in the patient's sera before and after exacerbations, and measure the immune reaction to the patient's own exacerbating strain, then compare these results to responses obtained with strains isolated when the patient was stable. Moxifloxacin achieved superior (p<0.05) bacteriological eradication (77%) compared with clarithromycin (62%) due to persistence of H. influenzae in clarithromycin treated patients. An algorithm showing which patients with an acute exacerbation of chronic obstructive pulmonary disease (COPD) should receive antibiotic treatment. White et al. Antibiotics or placebo were given in a randomised, double-blind, crossover fashion. Antibiotics for an acute exacerbation of COPD should be considered on an individual patient basis with uncertain benefit of antibiotics balanced against severity of symptoms, need for hospital treatment, exacerbation and hospitalisation history, risk of complications, and previous sputum culture results. In 2002, data from 360 hospitals reported that 69,820 US adults were hospitalised for an acute exacerbation of COPD (AECOPD) . Randomized controlled trials have demonstrated the effectiveness of multiple interventions. This finding adds weight to the argument that the bacteria are playing a key active role in the exacerbation as they are generating a host response intended to eliminate them. 7 days, cefuroxime 250 mg b.d. Antibiotics for exacerbations of chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease (acute exacerbation): antimicrobial prescribing. [23] showed that there were higher neutrophil counts, and elevated interleukin-8 and tumour necrosis factor-α levels in bronchoalveolar lavage performed on stable chronic bronchitic patients with LABC by potential pathogenic bacteria compared with those without. Patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) in whom outpatient treatment fails are at risk for serious decompensation and hospitalization.

Online ISSN: 1600-0617, Copyright © 2021 by the European Respiratory Society, Fletcher C, Peto R, Tinker C, Speizer FE. The hypothesis put forward was that incomplete bacterial eradication by the macrolide antibiotic lead to a shorter interval until the next exacerbation, although this remains a hypothesis to be tested and is not proven. Roede BM, Bresser P, Bindels PJE, et al. COPD (acute exacerbation): antimicrobial prescribing. The mechanism by which acquisition of a new strain leads to an exacerbation was not determined, but it is more likely that a new strain would not be recognised by the immune system, compared to a colonising strain that may have been present for several weeks, and this would allow it to multiply and so stimulate inflammatory responses that themselves lead to the symptoms of the exacerbation. Sethi et al. [F] Review intravenous antibiotics by 48 hours and consider stepping down to oral antibiotics where possible. Patients with chronic obstructive pulmonary disease (COPD) may experience an acute worsening of respiratory symptoms that results in additional therapy; this event is defined as a COPD exacerbation (AECOPD). Procalcitonin (PCT) may be helpful in determining if antibiotics are necessary or the duration of treatment. This hypothesis needs to be tested by further studies. It will become clear later in this article, that as well as identifying a potential bacterial pathogen from lower respiratory tract secretions, the strain should be fully identified and the numbers of bacteria calculated by quantitative sputum cultures. It will also enable services to match capacity to patient needs if services become limited because of the COVID-19 pandemic. Whenever COPD symptoms worsen, it's called an exacerbation or flare-up. The important lessons from the MOSAIC study for future trial design are: enrol patients when they are stable to obtain a baseline assessment by which to judge recovery; ensure an appropriate homogenous population (e.g. Patients were followed up monthly for 9 months after their exacerbation, and whether patients had risk-factors for poor outcome was taken into consideration. Patients can be taught to recognize a change in sputum from normal to purulent as a sign of impending exacerbation and to start a 10- to 14-day course of antibiotic therapy. Seek specialist advice for people with an acute exacerbation of COPD if they: have symptoms that are not improving with repeated courses of antibiotics, have bacteria that are resistant to oral antibiotics, cannot take oral medicines (to explore locally available options for giving intravenous antibiotics at home or in the community, rather than in hospital, where appropriate), When prescribing an antibiotic for an acute exacerbation of COPD, follow table 1 for adults aged 18 years and over, Give oral antibiotics first line if the person can take oral medicines, and the severity of their exacerbation does not require intravenous antibiotics, Review intravenous antibiotics by 48 hours and consider stepping down to oral antibiotics where possible, An exacerbation is a sustained worsening of the person’s symptoms from their usual stable state, which is beyond normal day-to-day variations, and is acute in onset. Isolation rates of H. influenzae and S. pneumoniae were identical during the stable phase and during an exacerbation. [27] carefully followed up 25 patients in clinic every 2 weeks for 4 yrs, leading to 1,870 stable sputum samples, 116 taken during exacerbations. However, the clinical outcome was equivalence, in that 89% of moxifloxacin-treated patients and 88% of clarithromycin-treated patients achieved a successful outcome. Source: Ram, FS, Rodriguez-Roisin, R, Granados-Navarrete, A, et al Antibiotics for exacerbations of chronic obstructive pulmonary disease. An exacerbation can … This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. [34] used the same cohort of patients as their previous study [15], and collected sputum and serum samples at each visit. The patients were assessed shortly after the end of treatment as before. [E] See MHRA advice for restrictions and precautions for using fluoroquinolone antibiotics due to very rare reports of disabling and potentially long-lasting or irreversible side effects affecting musculoskeletal and nervous systems. More recently, the Copenhagen City Study reported that patients with chronic mucus hypersecretion had more rapid rates of forced expiratory volume in one second (FEV1) decline than COPD patients without these symptoms [7]. Moxifloxacin gave superior outcomes in those patients not given steroids, but there was only a trend favouring moxifloxacin in patients given steroids. Another study found greater bacterial numbers during an exacerbation compared with the stable phase; a sputum Gram stain showed fewer than two organisms per oil immersion field when patients were stable compared with 8–18 per field at the time of an exacerbation [32]. These observations may be explained by the affinity with which bacteria adhere to mucus, and the delay in mucociliary clearance that occurs in chronic bronchitis, partly due to loss of ciliated cells that are replaced by goblet cells. Welcome to Guidelines. [41]. If no antibiotic is given, give advice about: symptoms (such as sputum colour changes and increases in volume or thickness) worsen rapidly or significantly, symptoms do not start to improve within an agreed time. Following discussions with colleagues the design of the studies has evolved to take into account issues raised in this article. Gump et al. About twice as many further courses of antibiotics were prescribed to comparator treated patients (14.1% versus 7.6%) in the few weeks following the presenting exacerbation, confirming incomplete resolution of symptoms, which led to further antibiotic prescriptions for these patients. The conclusions of this research, if accepted, must lead to new guidelines on the use of antibiotics in COPD, because present guidelines pay scan attention to the importance of antibiotic treatment in the overall management of COPD [1]. While research has shown that this approach does indeed lower your odds of exercerbations, antibiotic resistance is now a very serious global health concern. In another study Bandi et al. S. viridans. There is little information about the propensity of different species to stimulate inflammation, and even different strains of the same species may vary in their ability to elicit an inflammatory response [22]. Initially use intravenous Corticosteroids. [D] Co-trimoxazole should only be considered for use in acute exacerbations of COPD when there is bacteriological evidence of sensitivity and good reason to prefer this combination to a single antibiotic (BNF, October 2018). They showed that exacerbations were twice as likely to occur when patients acquired a new strain of either H. influenzae, the pneumococcus, or M. catarrhalis compared with visits when no new strain was isolated. Most of the bacterial species isolated from sputum during exacerbations of COPD colonise the nasopharynx of healthy individuals, and can be isolated from the lower airways of COPD patients during stable phases of their disease [1, 14]. The key results were that moxifloxacin achieved significantly (p<0.05) superior bacteriological eradication, which was again largely due to H. influenzae persistence in the comparator group. Those patients in whom bacteria continue to be cultured in the sputum only have partial resolution leading to chronic inflammation, which may be stimulated by the continued presence of bacteria in the airway. The recent studies of Sethi and colleagues [15, 34–36] suggest that when there is chronic colonisation by a single strain the immune response begins to wane with time. At the American Thoracic Society meeting in Orlando in May 2004 Sethi and colleagues [35, 36] showed new data indicating that the immune system does respond to some colonising strains, although the response is not as intense as when a new strain is acquired. The antibiotics for treating exacerbations of copd path for the chronic obstructive pulmonary disease pathway. Therefore, the host bacterial interaction is complex, and simply determining the presence or absence of a particular species by sputum bacteriology is inadequate for understanding the role of bacteria in COPD. An acute exacerbation of chronic obstructive pulmonary disease (COPD) is a sustained worsening of a person's symptoms from their usual stable state (beyond normal day-to-day variations) which is acute in onset. 1.2 Choice of antibiotic. A meta-analysis of placebo-controlled trials concluded that, overall, there was a small but significant benefit from antibiotic treatment of acute exacerbations of COPD in terms of overall recovery and change in peak flow [40]. Although there was considerable overlap between the two populations they found that patients carrying pathogenic species had more airway inflammation. Sivapalan P, Lapperre TS, Janner J, et al. Disadvantages of bronchoscopy include the difficulties associated with performing repeat studies, and sampling error, e.g. Acquisition of a new strain may not be a prerequisite for an exacerbation, since the numbers of a colonising strain might increase, and invasion of the mucosa might occur, if the host defences were reduced for example following a viral infection. The cure (return to baseline) rate with moxifloxacin was significantly (p<0.05) greater, but not the success (well enough not to require a further antibiotic) rate, which was the primary end-point and showed equivalence between the antibiotics. [41]. One may wonder whether omitting verification of a bacterial infection is justified, and … Procalcitonin (PCT) may be helpful in determining if antibiotics are necessary or the duration of treatment. 1,4,6–8,31 Antibiotics should only be used for the treatment of infectious 4,6,8,31 or severe exacerbations. The presence of bacteria in sputum alone during an exacerbation does not prove causation. However, sputum cultures were performed in only 14.4% of the patients. Lower respiratory tract infections caused more FEV1 decline in current smokers with mild COPD but not ex-smokers in the Lung Health Study [8]. When treating an exacerbation adding oral or intravenous corticosteroids and/or antibiotics is recommended, depending on symptom severity and the presence of infection. The proportion of patients with positive bacteriology, defined by quantitative counts and identification of species that are recognised as pathogens, increases to ∼50% during an exacerbation. Shortcomings of older antibiotic trials in acute exacerbations of chronic obstructive pulmonary disease. The frequency of exacerbations, whatever their cause, has been associated with more rapid loss of lung function, worse quality of life and quicker deterioration in quality of life [9, 10]. The most compelling evidence showing that bacterial infections are an important cause of exacerbations has been provided by the study of Sethi et al. Acute Exacerbation of Chronic Bronchitis Alpha-1-Antitrypsin Deficiency Chronic Bronchitis Chronic Obstructive Pulmonary Disease COPD Action Plan COPD Exacerbation Antibiotics COPD Exacerbation Prevention COPD Management COPD Staging Emphysema Medications in COPD Management Contemporary management of acute exacerbations of COPD: a systematic review and metaanalysis. for 5 days was compared with the macrolide antibiotic clarithromycin 500 mg b.d, for 7 days. Three antibiotics were used: amoxycillin, trimethoprim-sulphamethoxazole and doxycycline; the choice of antibiotic being made by the physician. These were reviewed by Murphy and Sethi [6]. Antibiotics may be prescribed in some cases of chronic obstructive pulmonary disease (COPD) during exacerbations (flare-ups) if there are signs of infection. Efficacy Endpoints: Mortality, Treatment Failure (Lack of resolution, worsening, or death) Harm Endpoints: Diarrhea Narrative: Chronic obstructive pulmonary disease (COPD), a term that encompasses both … About half of exacerbations yield positive sputum bacteriology, and the isolation rate can be increased by selection of purulent samples. [G] See the evidence and committee discussion on choice of antibiotic and antibiotic course length. If you continue to use the site, we will assume you are happy to accept the cookies anyway. [34] therefore measured antibodies directed against surface-exposed epitopes present on the actual strain in the airway during the exacerbation. JAMA. … Peak flow returned to baseline in both groups during the study period, but the rate of increase was faster in the antibiotic-treated exacerbations. Antibiotic therapy and treatment failure in patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease. Therefore, several studies have used a mixture of specific and cross-reactive antibodies, often with laboratory bacterial strains rather than strains obtained from the patient themselves [6, 33]. Chest 2008; 133:756. The debate about the importance of bacterial infection in chronic obstructive pulmonary disease will continue. [15]. VISUAL ABSTRACT CRP Testing to Guide Antibiotic Prescribing for COPD. Four bronchoscopy studies have given similar results: ∼25% of COPD patients have LABC when in a stable phase. The current author been the lead investigator in three studies conducted during the last 5 yrs or so, looking at the benefit of antibiotic treatment for COPD exacerbations. Antibiotics work by attacking the source of the infection. However, bacteria are also isolated in the stable state. Effect of reduced epithelial damagevia salmeterol on bacterial numbers. All antibiotic dosages listed below are based on normal renal and hepatic function. Chest 2013; 143:82. The answer to this “chicken and egg” argument would seem straightforward, because treating bacterial infection is something that is readily available with antibiotics. Cochrane Database Syst Rev 2006. Long-term antibiotic prophylaxis is recommended only for patients with underlying structural changes in the lung, such as bronchiectasis or infected bullae. So, if you do have COPD and a respiratory tract infection, your doctor will look for these early signs and may prescribe an antibiotic (usually amoxicillin or doxycycline) for you. However, bacteria are also isolated in the stable state. The hypothesis of the current author, to explain the results of MOSAIC, is that bacteriological eradication permitted the mucosal inflammation to fully resolve, and local host defences to repair themselves, leading to a longer exacerbation-free interval. 7 days, clarithromycin 500 mg b.d. One of the interests of the current author's group is the interaction of bacteria with the respiratory mucosa in organ cultures. Sethi et al. The purpose of this Guidelines summary is to maximise the safety of patients with cystic fibrosis and make the best use of NHS resources, while protecting staff from infection. ; Acute exacerbations of COPD can be triggered by a range of factors including respiratory tract infections (most commonly rhinovirus), smoking, and environmental pollutants. Biomarkers, such as C-reactive protein, may also be used to support a suspected bacterial infection; however, this is a nonspecific marker and its utility as a biomarker is controversial. Research has shown that if people with COPD are treated with antibiotics at the first sign of a respiratory infection (eg, a cold or flu), they are much less likely to be admitted to hospital. 7 days). Sethi et al. Patients with chronic bronchitis are more susceptible to bacterial bronchial infections than those at the emphysema or asthma end of the spectrum [1]. Airway bacterial load has been related to decline in FEV1, although this study was only conducted over 1 yr with assessment of bacteriology at the beginning and end [12]. Amoxycillin-clavulanate was compared with placebo and showed a clear overall superiority for the antibiotic treatment. The probable reason for this result is shown in table 3, which shows bacteriology results from paired sputum samples. The current author suspects that further work in this area will show that the host-bacterial relationships are even more complex than those described above. Patients with COPD have airways which chronically grow a variety of organisms. Both local and systemic inflammatory responses have been repeatedly demonstrated in COPD patients during exacerbations [1, 5, 6]. Soler et al. Antibiotic Guidance for Treatment of Acute Exacerbations of COPD (AECOPD) in Adults. About half of exacerbations yield positive sputum bacteriology, and the isolation rate can be increased by selection of purulent samples. [31] who found an increase in the frequency with which bacteria were isolated from the same patients during exacerbations compared to stable periods. Association between antibiotic treatment and outcomes in patients hospitalized with acute exacerbation of COPD treated with systemic steroids. [A] See the British national formulary (BNF) for appropriate use and dosing in specific populations, for example, hepatic impairment, renal impairment, and administering intravenous antibiotics. On day-30, no difference in symptom score, quality of life or serious adverse events was detected.Use of CRP as a biomarker to guide antibiotic treatment in severe acute exacerbations of COPD leads to a significant reduction in antibiotic treatment. [24] compared stable COPD patients with and without LABC by potential pathogenic species. Patients with chronic bronchitis and symptoms of an Anthonisen Type 1 or 2 exacerbation were enrolled. Methylprednisolone (Solumedrol) 60 mg IV every 6 hours; Avoid high doses (e.g. Download a PDF of this visual summary. There seemed in this study to be a level of 106 colony forming units per mL at which the inflammatory markers began to rise. Some studies have demonstrated that antibiotics can decrease the risk of short-term mortality, treatment failure, and sputum purulence in at least moderately severe patients with a COPD exacerbation. The role of antibiotics in acute exacerbations of chronic obstructive pulmonary disease (COPD) is controversial and a biomarker identifying patients who benefit from antibiotics is mandatory. In the Gemifloxacin Long-term Outcomes in Bronchitis Exacerbations (GLOBE) study [44], which followed TACTIC, the current author and colleagues asked the question whether H. influenzae persistence would influence the time interval until the next exacerbation. Antibiotics. All studies have in addition to potential pathogens identified bacterial species in the lower airways, which in health are sterile, that are not usually regarded as lower respiratory tract pathogens, e.g. Reassess people with an acute exacerbation of COPD if their symptoms worsen rapidly or significantly at any time, taking account of: other possible diagnoses, such as pneumonia, any symptoms or signs suggesting a more serious illness or condition, such as cardiorespiratory failure or sepsis, previous antibiotic use, which may have led to resistant bacteria, Refer people with an acute exacerbation of COPD to hospital if they have any symptoms or signs suggesting a more serious illness or condition (for example, cardiorespiratory failure or sepsis) and in line with the NICE guideline on. In the case of COPD, some patients have been prescribed continuous prophylactic antibiotics, while others are offered them intermittently, with the goal of reducing the risk of exerbations. Warnings include: stopping treatment at first signs of a serious adverse reaction (such as tendonitis), prescribing with special caution in people over 60 years and avoiding coadministration with a corticosteroid (March 2019). Three levels of severity of exacerbation were recognised: the most severe (type 1) comprised of worsening dyspnoea with increased sputum volume and purulence, type 2 was any two of these symptoms and the least severe grade (type 3) was any one of three symptoms with evidence of fever or an upper respiratory tract infection. Management: Severe Exacerbation requiring hospitalization. The goal of antibiotic therapy is generally to suppress this bacterial growth a bit, not to completely sterilize the patient's lungs (which is impossible in this … About half of exacerbations yield positive sputum bacteriology, and the isolation rate may be increased by selection of purulent samples [16, 17]. [C] People who may be at a higher risk of treatment failure include people who have had repeated courses of antibiotics, a previous or current sputum culture with resistant bacteria, or people at higher risk of developing complications.
