JAMA. 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. 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. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Gump et al. 7 days, clarithromycin 500 mg b.d. However, bacteria are also isolated in the stable state. There was a significant benefit from antibiotics that was largely accounted for by patients with type 1 exacerbations, whereas there was no significant difference between antibiotic and placebo in patients who only had one of the defined symptoms. This site is intended for UK healthcare professionals, Guidelines Live 2020—now available on demand, Managing an acute exacerbation of COPD with antibiotics, acute exacerbation of chronic obstructive pulmonary disease, NICE - COPD (acute exacerbation) antimicrobial prescribing, PHE launches nationwide Every Mind Matters campaign, COVID-19 rapid guideline: cystic fibrosis, Identifying and managing allergic rhinitis in the asthma population, a range of factors (including viral infections and smoking) can trigger an exacerbation, some people at risk of exacerbations may have antibiotics to keep at home as part of their exacerbation action plan (see the recommendations on, Consider an antibiotic (see the recommendations on, the severity of symptoms, particularly sputum colour changes and increases in volume or thickness beyond the person’s normal day-to-day variation, whether they may need to go into hospital for treatment (see the NICE guideline on, previous exacerbation and hospital admission history, and the risk of developing complications, previous sputum culture and susceptibility results, the risk of antimicrobial resistance with repeated courses of antibiotics, If a sputum sample has been sent for culture and susceptibility testing (in line with the NICE guideline on, review the choice of antibiotic when results are available, only change the antibiotic according to susceptibility results if bacteria are resistant and symptoms are not already improving (using a narrow-spectrum antibiotic wherever possible), about possible adverse effects of the antibiotic, particularly diarrhoea, that symptoms may not be fully resolved when the antibiotic course has been completed, symptoms do not start to improve within 2–3 days (or other agreed time), the person becomes systemically very unwell. Following discussions with colleagues the design of the studies has evolved to take into account issues raised in this article. Antibiotic therapy and treatment failure in patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease. 125 mg) as they offer no added benefit; Transition to oral Corticosteroids as soon as prudent. 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 This management algorithm was developed by a multidisciplinary expert panel: Scadding et al with the support of an educational grant from Mylan. About half of exacerbations yield positive sputum bacteriology, and the isolation rate may be increased by selection of purulent samples [16, 17]. Patients with COPD have airways which chronically grow a variety of organisms. 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. LABC is a dynamic process, so that strains may be carried for variable periods of time before being lost and replaced by others. LABC has also been linked to FEV1 decline, as well as the frequency and severity of subsequent exacerbations [12, 13]. 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. The new evidence can be considered under six headings: 1) lung function decline; 2) bronchoscopic studies; 3) epidemiology using new molecular biology techniques to identify bacteria; 4) immunology; 5) studies of airway inflammation; and 6) recent antibiotic studies. [41]. 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. In this study 173 patients with COPD were followed for 3.5 yrs during which time they had 362 exacerbations. 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. Patients receiving procalcitonin-guided therapy were treated with antibiotics according to serum procalcitonin levels; standard-therapy patients received antibiotics according to the attending physician. Three antibiotics were used: amoxycillin, trimethoprim-sulphamethoxazole and doxycycline; the choice of antibiotic being made by the physician. COPD (acute exacerbation): antimicrobial prescribing. The evidence reviewed above, taken together with the wealth of evidence that bacterial products generate inflammation [1], makes a strong case for bacterial infection being the cause, or at least making a significant contribution, to about half of exacerbations. Commonly reported symptoms are worsening breathlessness, cough, increased sputum production and change in sputum colour (, A general classification of the severity of an acute exacerbation (, mild exacerbation: the person has an increased need for medication, which they can manage in their own normal environment, moderate exacerbation: the person has a sustained worsening of respiratory status that requires treatment with systemic corticosteroids and/or antibiotics, severe exacerbation: the person experiences a rapid deterioration in respiratory status that requires hospitalisation, The presence of all 3 symptoms was defined as type 1 exacerbation; 2 of the 3 symptoms was defined as type 2 exacerbation; and 1 of the 3 symptoms with the presence of 1 or more supporting symptoms and signs was defined as type 3 exacerbation. 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). Antibiotics are not recommended for all patients with AECOPD as bacterial infection is implicated in less than one-third of AECOPD. There is general agreement that the three species listed above are most commonly isolated from sputum during acute exacerbations, but several studies have shown that they can also be isolated from patients sputum during stable periods [27–30]. As yet no longitudinal study has been performed to examine the same patients whilst stable and exacerbated. Current cigarette smoking predisposes to LABC, but studies have disagreed whether airflow obstruction is a predisposing factor. 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]. 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 … [B] If a person is receiving antibiotic prophylaxis, treatment should be with an antibiotic from a different class. Welcome to Guidelines. 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. They suggested that chronic bronchitis and airflow obstruction were both caused by cigarette smoking, but the former that was associated with bronchial infections involved major conducting airways, whereas the latter related to small airways. When treating an exacerbation adding oral or intravenous corticosteroids and/or antibiotics is recommended, depending on symptom severity and the presence of infection. [24] compared stable COPD patients with and without LABC by potential pathogenic species. Lower airway bacterial colonisation (LABC) during a stable phase of COPD probably represents a balance in which the impaired host defences are able to limit the numbers of bacteria, but not eradicate them. Two other findings of this study are important. Sethi et al. Antibiotic Guidance for Treatment of Acute Exacerbations of COPD (AECOPD) in Adults. Medicines management. Oral corticosteroids are likely beneficial, especially for patients with purulent sputum. [F] Review intravenous antibiotics by 48 hours and consider stepping down to oral antibiotics where possible. Stefan MS, Rothberg MB, Shieh MS, et al. 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. 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. They have reported the cytoprotective effects in these systems of the long-acting β2 agonist salmeterol [39]. The design of the study was standard, with the primary end-point at day 14 being physician judgement that the patient had improved sufficiently not to require further antibiotic treatment. 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. In the first study conducted by the current author, Treatment of Acute exaCerbaTions of chronIC bronchitis (TACTIC) [43], the quinolone antibiotic moxifloxacin 400 mg o.d. 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. Patients sick enough to be in the ICU due to COPD should receive antibiotics (even if there is no infiltrate on the chest X-ray)(Vollenweider et al 2012). Download a PDF of this visual summary. Randomized controlled trials have demonstrated the effectiveness of multiple interventions. An algorithm showing which patients with an acute exacerbation of chronic obstructive pulmonary disease (COPD) should receive antibiotic treatment. [34] used the same cohort of patients as their previous study [15], and collected sputum and serum samples at each visit. for 5 days or one of a basket of three comparator antibiotic chosen because they were the most common antibiotics (and dosages) used in the countries enrolling patients into the trial (amoxycillin 500 mg t.d.s. 87% of these patients were treated with antibiotics, resulting in broad-spectrum coverage in 74% of cases. When patients acquired a new strain at the time of an exacerbation, a specific antibody response to this strain was present 58.3% of the time, whilst only 15.2% of exacerbations with a persistent colonising strain had an antibody response. [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. 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. 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. However, recent data has led to a re-examination of the role of bacterial infection in COPD, and a revisiting of the “British hypothesis” [5]. A single infective exacerbation has a sustained affect on health status, and recovery is markedly impaired by a second exacerbation within a 6-month follow-up period [11]. 1.2.1 When prescribing an antibiotic for an acute exacerbation of COPD, follow table 1 for adults aged 18 years and over. These were reviewed by Murphy and Sethi [6]. Banerjee et al. However, bacteria are also isolated in the stable state. This guideline sets out an antimicrobial prescribing strategy for acute exacerbations of chronic obstructive pulmonary disease (COPD). Since LABC is a dynamic process, in that multiple bacterial strains may be carried at any one time, and they are sometimes changeable on a week-by-week basis, it might be a very unstable relationship [1]. [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. New evidence has been obtained from epidemiological, immunological and antibiotic studies that supports a role for bacterial infection in causing neutrophilic airway inflammation in chronic obstructive pulmonary disease, and if accepted should lead to new research in the use of antibiotics. Thirteen of 15 biopsy samples in a study of patients with severe exacerbations were positive for H. influenzae detected by monoclonal antibody [26]. 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]. [41]. [15]. 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]. In the present study, no differences in adverse events between both groups were found. Association between antibiotic treatment and outcomes in patients hospitalized with acute exacerbation of COPD treated with systemic steroids. Therefore, the design of future long-term studies should involve seeing patients regularly, whatever their clinical status, as well as asking them to present to the centre during all exacerbations [9, 14, 15]. Therefore, there may be a level of bacterial load that is tolerated but this is likely to be dependent on the species and strains being carried. antibiotics. Most have leaned heavily on the study by Anthonisen et al. Acute exacerbation of COPD (AECOPD) often leads to dyspnoea, frequent cough, and a significant increase in sputum volume. About half of exacerbations yield positive sputum bacteriology, and the isolation rate can be increased by selection of purulent samples. Perception of what is a pathogenic species can change with time, for example M. catarrhalis was not regarded as a pathogen for many years, and there is a debate at the present time about H. parainfluenzae [1]. They have not taken into account the antigenic complexity of bacterial antigens of which those expressed on the surface are most relevant to the host-bacterial interactions, nor of the human immune response to those antigens. 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]. Treatment of COPD exacerbations: antibiotics R. Wilson ABSTRACT: The debate about the importance of bacterial infection in chronic obstructive pulmonary disease will continue. Finally, bacterial colonisation of the bronchial tree in between exacerbations has been shown to be associated with both an increase in the severity and frequency of future exacerbations [13]. However, sputum cultures were performed in only 14.4% of the patients. The evidence as it stands at the moment is suggestive that bacterial infections may have a role in progression of COPD, but it is far from conclusive. This hypothesis needs to be tested by further studies. We do not capture any email address. Moxifloxacin achieved superior (p<0.05) bacteriological eradication (77%) compared with clarithromycin (62%) due to persistence of H. influenzae in clarithromycin treated patients. Chest 2008; 133:756. Background: Many patients with an exacerbation of chronic obstructive pulmonary disease (COPD) are treated with antibiotics. Sethi et al. 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. Another new quinolone antibiotic, gemifloxacin, was compared with clarithromycin using a very similar study design, but in this study only Anthonisen type 1 exacerbations were enrolled and patients followed up for 26 weeks or until they had their next exacerbation. Steroids may have improved outcomes in the comparator group, making it more difficult to demonstrate differences between antibiotics. Hospitalization for AECOPD is accompanied by a rapid decline in health status with a high risk of mortality or other negative outcomes such as need for endotracheal intubation or … Treatment depends on the type and severity of the exacerbation and can include bronchodilators, corticosteroids, antibiotics, oxygen therapy, … 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. 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. 7 days, cefuroxime 250 mg b.d. There have been conflicting results. In patients with frequent exacerbations the duration of antibiotic-treated exacerbations averaged 2.2 days less than those treated with placebo (p = 0.02). In 2002, data from 360 hospitals reported that 69,820 US adults were hospitalised for an acute exacerbation of COPD (AECOPD) . All rights reserved. This may be relevant because of the association between mucus hypersecretion and bacterial infection. 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. The same findings were seen with the bactericidal assay, and only 12% of heterologous strains of H. influenzae were killed. However, the value of antibiotics remains uncertain, as systematic reviews and clinical trials have shown conflicting results. Contemporary management of acute exacerbations of COPD: a systematic review and metaanalysis. 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. 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.

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]. Other medicines. [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. It will also enable services to match capacity to patient needs if services become limited because of the COVID-19 pandemic. 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. 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. ; Acute exacerbations of COPD can be triggered by a range of factors including respiratory tract infections (most commonly rhinovirus), smoking, and environmental pollutants. 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. Following a survey that revealed the impact COVID-19 has had on adults’ mental wellbeing across the country, Public Health England has launched a new campaign to support mental health, This standard operating procedure (SOP) summary describes the operating model and design requirements for safe delivery of COVID-19 vaccines in the community, This concise and useful summary covers monitoring of women vaccinated in pregnancy or shortly before conception. Long-term antibiotic prophylaxis is recommended only for patients with underlying structural changes in the lung, such as bronchiectasis or infected bullae. 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. © NICE 2018. Co-administer Corticosteroids. [25], and that such invasion would cause epithelial damage and stimulate higher levels of inflammation. [37] showed that resolution of bronchial inflammation following an exacerbation is dependent upon bacterial eradication. The patients were assessed shortly after the end of treatment as before. 2010;303:2035-2042. [25] examined biopsies taken from 15 critically ill patients with an acute exacerbation and found H. influenzae within the mucosa of 13. 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. The most compelling evidence showing that bacterial infections are an important cause of exacerbations has been provided by the study of Sethi et al. An exacerbation can … Patients were followed up monthly for 9 months after their exacerbation, and whether patients had risk-factors for poor outcome was taken into consideration. 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 . Here are five treatments that can help restore normal breathing during an episode. New York, Toronto, Oxford University Press, 1976. They found that plasma fibrinogen levels were higher in patients with sputum pathogens, and also that quality-of-life scores were worse in this group. 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). 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 Table 1 shows that this compound, which has no antibacterial action, reduced the number of Pseudomonas aeruginosa on the organ culture by reducing the amount of mucosal damage that occurred during infection. [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). 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). Shortcomings of older antibiotic trials in acute exacerbations of chronic obstructive pulmonary disease. About half of exacerbations yield positive sputum bacteriology, and the isolation rate can be increased by selection of purulent samples. … 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]. Antibiotic Guidance for Treatment of Acute Exacerbations of COPD (AECOPD) in Adults Antibiotics are not recommended for most patients with AECOPD. The primary outcome was the antibiotic exposure at the index exacerbation and the subsequent antibiotic requirement for COPD exacerbation within 6 months. Two of the five trials that showed no benefit did show significantly less time lost from work in the antibiotic group, even though the frequency of exacerbations was not different from the placebo group. Subject to Notice of rights. The bacterium was also found in the tissue taken from eight of 24 stable COPD patients but none of seven healthy controls. Five trials showed no reduction in the frequency of exacerbations whereas four did show this benefit. The species identified are predominantly one of the three given above and the bacterial numbers are much greater during an exacerbation [18–21]. Patients most likely to benefit from continuous antibiotic treatment were found to be those suffering frequent exacerbations, which was judged to mean of at least four per year. The reason that the debate continues is that antibiotic trials have not provided the expected conclusive answer. The opinion of the current author favours the recent Canadian guidelines [47], which advocate the use of particular antibiotics that have been shown to achieve superior bacteriological eradication for patients with risk factors for poor outcomes (severe chronic obstructive pulmonary disease box in algorithm). Chronic obstructive pulmonary disease (acute exacerbation): antimicrobial prescribing. The analysis also showed that patients with more severe impairment of FEV1 and with a history of more frequent exacerbations derived greatest benefit.
