WHO's essential medicines and AWaRe: recommendations on first- and second-choice antibiotics for empiric treatment of clinical infections. Clin Microbiol Infect 2024; 30 Suppl 2:S1-S51. [PMID: 38342438 DOI: 10.1016/j.cmi.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/26/2024] [Accepted: 02/04/2024] [Indexed: 02/13/2024]
Abstract
The WHO Model List of Essential Medicines (EML) prioritizes medicines that have significant global public health value. The EML can also deliver important messages on appropriate medicine use. Since 2017, in response to the growing challenge of antimicrobial resistance, antibiotics on the EML have been reviewed and categorized into three groups: Access, Watch, and Reserve, leading to a new categorization called AWaRe. These categories were developed taking into account the impact of different antibiotics and classes on antimicrobial resistance and the implications for their appropriate use. The 2023 AWaRe classification provides empirical guidance on 41 essential antibiotics for over 30 clinical infections targeting both the primary health care and hospital facility setting. A further 257 antibiotics not included on the EML have been allocated an AWaRe group for stewardship and monitoring purposes. This article describes the development of AWaRe, focussing on the clinical evidence base that guided the selection of Access, Watch, or Reserve antibiotics as first and second choices for each infection. The overarching objective was to offer a tool for optimizing the quality of global antibiotic prescribing and reduce inappropriate use by encouraging the use of Access antibiotics (or no antibiotics) where appropriate. This clinical evidence evaluation and subsequent EML recommendations are the basis for the AWaRe antibiotic book and related smartphone applications. By providing guidance on antibiotic prioritization, AWaRe aims to facilitate the revision of national lists of essential medicines, update national prescribing guidelines, and supervise antibiotic use. Adherence to AWaRe would extend the effectiveness of current antibiotics while helping countries expand access to these life-saving medicines for the benefit of current and future patients, health professionals, and the environment.

Procalcitonin Monitoring and Antibiotic Duration in Presumed Lower Respiratory Tract Infections: A Propensity Score-Matched Cohort Across the Veterans Health Administration. Open Forum Infect Dis 2023; 10:ofad520. [PMID: 37942465 PMCID: PMC10629903 DOI: 10.1093/ofid/ofad520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 10/23/2023] [Indexed: 11/10/2023] Open
Abstract
Background Randomized controlled trials have shown that procalcitonin-guided algorithms can reduce antibiotic duration for lower respiratory tract infections (LRTIs). The goal of this study was to compare antibiotic duration for LRTIs with and without procalcitonin testing in real-life practice. Methods This retrospective cohort study included all acute care hospital admissions for presumed LRTIs between 1/2018 and 12/2021 at 81 Veterans Affairs facilities with on-site procalcitonin testing. The exposure was procalcitonin testing; the primary outcome was antibiotic duration. We used 1:1 nearest-neighbor propensity score matching to estimate the difference in outcome between procalcitonin-tested and nontested patients. Results A total of 35 610 patients with LRTIs were included (6015 [16.9%] with procalcitonin testing; 29 595 [83.1%] without testing). In tested patients, the median number of procalcitonin levels checked (interquartile range) was 2 (1-3). The mean antibiotic duration was 10.0 days in the procalcitonin group compared with 8.3 days in nontested patients (unadjusted difference, 1.7 days; P < .0001). After propensity score matching with 3903 pairs, antibiotic duration remained greater in the procalcitonin group (9.6 days vs 9.2 days; P < .0001). In a subgroup analysis of 2241 tested patients with a procalcitonin value at the standard threshold for antibiotic discontinuation, antibiotic duration was shorter in tested vs nontested patients, with a mean difference of 0.1 days (P < .01). Conclusions In this retrospective propensity-matched cohort of patients with presumed LRTIs across a geographically diverse group of hospitals, patients who underwent procalcitonin testing did not have a meaningful reduction in antibiotic duration compared with those who were not tested. Poor implementation of procalcitonin testing may have undermined its effectiveness.

Are short courses of antibiotic therapy as effective as standard courses for COPD exacerbations? A systematic review and meta-analysis. Pulm Pharmacol Ther 2022; 72:102111. [PMID: 35032637 DOI: 10.1016/j.pupt.2022.102111] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 10/14/2021] [Accepted: 01/10/2022] [Indexed: 12/30/2022]
Abstract
BACKGROUND The best duration of antibiotic treatment for chronic obstructive pulmonary disease (COPD) exacerbations is uncertain. OBJECTIVE To evaluate whether a short course of antibiotic therapy is as effective as the standard longer treatment for exacerbations of patients with COPD. METHODS We searched Pubmed/MEDLINE and trials in relevant systematic reviews from the inception up to March 2021, with no language restrictions. Randomised controlled trials comparing short-course antibiotic therapy (≤5 days) with standard antibiotic therapy (≥6 days) for exacerbations of patients aged ≥40 with spirometrically-confirmed COPD were included. Three outcomes were considered: end-of-therapy clinical cure, bacterial eradication and adverse events. Statistical analyses included random effects meta-analyses using odds ratios and assessment of heterogeneity. RESULTS Of 1274 citations found, eight were eligible for inclusion, seven of which recruited outpatients. Overall, short-course antibiotic treatments were not significantly different from those of long-course treatments for clinical cure (odds ratio [OR] 1.14, 95% CI 0.91; 1.44) and for bacterial eradication (OR 1.16, 95% CI 0.91; 1.48). Adverse events were observed in 379 (21.1%) patients receiving short-term antibiotic regimens, while 412 (22.8%) patients receiving the standard regimens reported adverse events (OR 0.83, 95% CI 0.62; 1.11). The heterogeneity of the studies was low. CONCLUSION In relation to clinical and bacteriological efficacy, a short course of antibiotic treatment is equivalent to longer conventional treatment in mainly outpatients with exacerbations of COPD. Moreover, shorter exposure to antibiotics may decrease the risk developing antimicrobial resistance and, hence, might become first-line therapy for the management of ambulatory COPD patients.

Abstract
Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with high rates of hospitalizations, costs, and morbidity. Therefore, hospitalists and the multidisciplinary team (hospital team) need to take a proactive approach to ensure patients are effectively managed from hospital admission to postdischarge. Comprehensive screening and diagnostic testing of patients at admission will enable an accurate diagnosis of COPD exacerbations, and severity, as well as other factors that may impact the length of hospital stay. Depending on the exacerbation severity and cause, pharmacotherapies may include short-acting bronchodilators, systemic corticosteroids, and antibiotics. Oxygen and/or ventilatory support may benefit patients with demonstrable hypoxemia. In preparation for discharge, the hospital team should ensure that patients receive the appropriate maintenance therapy, are counseled on their medications including inhalation devices, and proactively discuss smoking cessation and vaccinations. For follow-up, effective communication can be achieved by transferring discharge summaries to the primary care physician via an inpatient case manager. An inpatient case manager can support both the hospitalist and the patient in scheduling follow-up appointments, sending patient reminders, and confirming that a first outpatient visit has occurred. A PubMed search (prior to 26 January 2021) was conducted using terms such as: COPD, exacerbation, hospitalization. This narrative review focuses on the challenges the hospital team encounters in achieving optimal outcomes in the management of patients with COPD exacerbations. Additionally, we propose a novel simplified algorithm that may help the hospital team to be more proactive in the diagnosis and management of patients with COPD exacerbations.

Abstract
BACKGROUND There is growing evidence supporting the efficacy of shorter courses of antibiotic therapy for common infections, however the risks of prolonged antibiotic duration are underappreciated. OBJECTIVES We sought to estimate the incremental daily risk of antibiotic-associated harms. METHODS We searched three major databases to retrieve systematic reviews from 2000 to July 30, 2020 in any language. ELIGIBILITY Systematic reviews were required to evaluate shorter versus longer antibiotic therapy with fixed durations between 3 and 14 days. RCTs included for meta-analysis were identified from the systematic reviews. PARTICIPANTS Adult and pediatric patients from any setting. INTERVENTIONS Primary outcomes were the proportion of patients experiencing adverse drug events, superinfections and antimicrobial resistance. Risk of Bias Assessment: Each RCT was evaluated for quality by extracting the assessment reported by each systematic review. DATA SYNTHESIS The daily odds ratio (OR) of antibiotic harm was estimated and pooled using random effects meta-analysis. RESULTS Thirty-five (35) systematic reviews encompassing 71 eligible randomized controlled trials were included. Studies most commonly evaluated duration of therapy for respiratory tract (n=36, 51%) and urinary tract infections (n=29, 41%). Overall, 23,174 patients were evaluated for antibiotic-associated harms. Adverse events (n=20,345), superinfections (n=5,776), and AMR (n=2,330) were identified in 19.9% (n=4,039), 4.8% (n=280), and 10.6% (n=246) of patients, respectively. Each day of antibiotic therapy was associated with 4% increased odds of experiencing an adverse event (OR 1.04, 95% CI [1.02 to 1.07]). Daily odds of severe adverse effects also increased (OR 1.09, 95% CI [1.00 to 1.19). The daily incremental odds of superinfection and AMR were OR 0.98 (0.92 to 1.06) and OR 1.03 (0.98 to 1.07), respectively. CONCLUSION Each additional day of antibiotic therapy is associated with measurable antibiotic harm, particularly adverse events. These data may provide additional context for clinicians when weighing benefits versus risks of prolonged antibiotic therapy.

Abstract
Patients who suffer from chronic obstructive pulmonary disease (COPD) often experience deterioration of baseline respiratory symptoms, acute exacerbations of COPD (AECOPD), that become more frequent with disease progression. Based on symptom severity, approximately 20% of these patients will require hospitalization. The most common indicators for intensive care unit (ICU) admission have been found to be worsening or impending respiratory failure and hemodynamic instability. Bacterial and viral bronchial infections are the causative triggers in the majority of COPD exacerbations in the ICU, with a comprehensive assessment revealing them in 72% of cases. The distribution of bacterial pathogens involved in AECOPD requiring ICU admission show an increased incidence of gram-negative respiratory isolates, including Pseudomonas and Enterobacteriaceae spp., when compared with outpatient exacerbations. Evaluation of these patients requires careful attention to comorbid conditions. An effort to rapidly obtain lower respiratory samples for microbiological samples prior to initiation of antibiotics should be made as adequate samples can guide subsequent modifications of antibiotic treatment if the clinical response to empiric treatment is poor. Empiric antibiotic treatment should be promptly initiated in all patients with a major consideration for the choice being the presence of risk factors for Pseudomonas infection. Evaluation of clinical response at 48 to 72 hours is crucial, and total duration of antibiotics of 5 to 7 days should be adequate.

Abstract
Asthma and chronic obstructive pulmonary disease (COPD) cause significant morbidity and mortality worldwide, primarily through exacerbations. Exacerbations are often treated with antibiotics but their optimal course duration is uncertain. Reducing antibiotic duration may influence antimicrobial resistance but risks treatment failure. The objective of this article is to review published literature to investigate whether shorter antibiotic therapy duration affects clinical outcomes in the treatment of asthma and COPD exacerbations. We systematically searched electronic databases (MEDLINE, EMBASE, CINAHL, World Health Organisation International Clinical Trial Registry Platform, the Cochrane library, and ISRCTN) with no language, location, or time restrictions. We retrieved observational and controlled trials comparing different durations of the same oral antibiotic therapy in the treatment of acute exacerbations of asthma or COPD in adults. We found no applicable studies for asthma exacerbations. We included 10 randomized, placebo-controlled trials for COPD patients, all from high-income countries. The commonest studied antibiotic class was fluoroquinolones. Antibiotic courses shorter than 6 days were associated with significantly fewer overall adverse events (risk ratio (RR): 0.84, 95% confidence interval (CI): 0.75-0.93, p = 0.001) when compared with those of 7 or more days. There was no statistically significant difference for clinical success or bacteriological eradication in sputum (RR: 1.00, 95% CI: 0.88-1.13 and RR: 1.06, 95% CI: 0.79-1.44, respectively). Shorter durations of antibiotics for COPD exacerbations do not seem to confer a higher risk of treatment failure but are associated with fewer adverse events. This is in keeping with previous studies in community acquired pneumonia, but studies were heterogeneous and differed from usual clinical practice. Further observational and prospective work is needed to explore the significance of antibiotic duration in the treatment of asthma and COPD exacerbations.

Abstract
Lower respiratory tract infections are the leading cause of infectious disease deaths worldwide and are the fifth leading cause of death overall. This is despite conditions such as pneumococcal infections and influenza being largely preventable with the use of appropriate vaccines. The mainstay of treatment for the most important bacterial lower respiratory tract infections, namely acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and community-acquired pneumonia (CAP), is the use of antibiotics. Yet despite a number of recent publications, including clinical studies as well as several systematic literature reviews and meta-analyses, there is considerable ongoing controversy as to what the most appropriate antibiotics are for the empiric therapy of CAP in the different settings (outpatient, inpatient, and intensive care unit). Furthermore, in the case of AECOPD, there is a need for consideration of which of these exacerbations actually need antibiotic treatment. This article describes these issues and makes suggestions for appropriately managing these conditions, in the setting of the need for antimicrobial stewardship initiatives designed to slow current emerging rates of antibiotic resistance, while improving patient outcomes.

Abstract
The purpose of this study was to compare the relative efficacy and safety of different antibiotic drugs and recommend superior regimens in the treatment of bronchitis. With respect to the antibiotic comparisons against quinolones in terms of intention-to-treat patients, we concluded that quinolones had advantages over placebo, β-lactams, sulfonamides, and double β-lactams. Concerning treatment methods for clinically evaluable patients, quinolones demonstrated better performance than β-lactams and sulfonamides. The secondary effects of macrolides, quinolones, and double β-lactams were significantly more adverse than β-lactams with odds ratios (ORs) of 1.5 (95% credible interval [CrI] =1.1–2.0), 1.7 (95% CrI =1.2–2.3), and 2.7 (95% CrI =1.8–4.1), respectively. Significant differences in the prevalence of diarrhea as a secondary effect were only identified among the comparisons of double β-lactams against β-lactams and macrolides (OR =5.0, 95% CrI =2.1–12.0; OR =3.0, 95% CrI =1.7–5.4, respectively). Quinolones can be recommended as the superior treatment for bronchitis, in accordance with our cluster analysis with surface under the cumulative ranking curve. The primary outcomes of network meta-analysis indicated that quinolones showed the best performance among the 8 treatments studied, although β-lactams showed the lowest risk of adverse side effects. Quinolones are recommended as the primary treatment option for bronchitis patients, having taking into account the success rates and safety profiles of the eight drugs studied here.

Abstract
Chronic infections are associated with exacerbation in patients with chronic obstructive pulmonary disease (COPD). The major objective of the management of these patients is the prevention and effective treatment of exacerbations. Patients that have increased sputum production, associated with purulence and worsening shortness of breath, are the ones that will benefit from antibiotic therapy. It is important to give the appropriate antibiotic therapy to prevent treatment failure, relapse, and the emergence of resistant pathogens. In some patients, systemic corticosteroids are also indicated to improve symptoms. In order to identify which patients are more likely to benefit from these therapies, clinical guidelines recommend stratifying patients based on their risk factor associated with poor outcome or recurrence. It has been identified that patients with more severe disease, recurrent infection and presence of purulent sputum are the ones that will be more likely to benefit from this therapy. Another approach related to disease prevention could be the use of prophylactic antibiotics during steady state condition. Some studies have evaluated the continuous or the intermittent use of antibiotics in order to prevent exacerbations. Due to increased bacterial resistance to antibiotics and the presence of side effects, several antibiotics have been developed to be nebulized for both treatment and prevention of acute exacerbations. There is a need to design long-term studies to evaluate these interventions in the natural history of the disease. The purpose of this publication is to review our understanding of the role of bacterial infection in patients with COPD exacerbation, the role of antibiotics, and future interventions.

Abstract
OBJECTIVES Reducing antibiotic consumption has now become a major public health priority. Reducing treatment duration is one of the means to achieve this objective. Guidelines on the therapeutic management of the most frequent infections recommend ranges of treatment duration in the ratio of one to two. The Recommendation Group of the French Infectious Diseases Society (SPILF) was asked to collect literature data to then recommend the shortest treatment durations possible for various infections. METHODS Analysis of the literature focused on guidelines published in French and English, supported by a systematic search on PubMed. Articles dating from one year before the guidelines publication to August 31, 2015 were searched on the website. RESULTS The shortest treatment durations based on the relevant clinical data were suggested for upper and lower respiratory tract infections, central venous catheter-related and uncomplicated primary bacteremia, infective endocarditis, bacterial meningitis, intra-abdominal, urinary tract, upper reproductive tract, bone and joint, skin and soft tissue infections, and febrile neutropenia. Details of analyzed articles were shown in tables. CONCLUSION This work stresses the need for new well-conducted studies evaluating treatment durations for some common infections. Following the above-mentioned work focusing on existing literature data, the Recommendation Group of the SPILF suggests specific study proposals.

Abstract
The 2010 Global Burden of Disease Study reported that lower respiratory tract infections, including pneumonia, are the fourth most common cause of death globally. The etiology of acute bronchitis and asthma exacerbations is mostly viral and the therapy is symptomatic. Management decisions in community acquired pneumonia regarding site of care, extent of assessment, and level of treatment are based primarily on disease severity (outpatient, inpatient, ICU admission). Antibiotics are the main choice of treatment for patients with pneumonia, acute exacerbations (AE) of COPD (including increased sputum purulence and worsening shortness of breath) and AE of non-CF bronchiectasis. Inhaled antibiotics may represent a more optimal approach for the treatment and prevention of AE of non-CF bronchiectasis. Approved strategies for the prevention of exacerbations include smoking cessation and rehabilitation programs, drug therapy and vaccination.

Abstract
A decade of rapid technological advances has provided an exciting opportunity to incorporate information relating to a range of potentially important disease determinants in the clinical decision-making process. Access to highly detailed data will enable respiratory medicine to evolve from one-size-fits-all models of care, which are associated with variable clinical effectiveness and high rates of side-effects, to precision approaches, where treatment is tailored to individual patients. The human microbiome has increasingly been recognised as playing an important part in determining disease course and response to treatment. Its inclusion in precision models of respiratory medicine, therefore, is essential. Analysis of the microbiome provides an opportunity to develop novel prognostic markers for airways disease, improve definition of clinical phenotypes, develop additional guidance to aid treatment selection, and increase the accuracy of indicators of treatment effect. In this Review we propose that collaboration between researchers and clinicians is needed if respiratory medicine is to replicate the successes of precision medicine seen in other clinical specialties.

Abstract
In the last decade, there has been an exponential increase in the microorganisms resistant to antimicrobials and a significant increase in the cost of these types of drugs. This phenomenon has increased interest in the development of interventions for counseling on and control of the use of antimicrobials, referred to as stewardship programs. In this article we review, from various points of view, the tools that have been developed with this purpose. First, we highlight the value of locally adapted guidelines and clinical pathways as an essential part of the operational process. Then we emphasize the importance of the relationship between microbiologists and clinicians for the accurate transmission of the information provided by blood cultures to make the most appropriate choice of antimicrobial for the patient's treatment. We also review the computerized tools that have facilitated the correct use of antimicrobials according to the controls established by the departments of pharmacy. Based on the previous tools, some programs based on "bedside recommendations" provided by multidisciplinary teams have been developed for optimizing the rational use of antimicrobials (PROA programs). Finally, we comment on the peculiarities of the programs targeting antifungals that have been developed in recent years.

Abstract
Chorioamnionitis is common in females with prematurely ruptured fetal membranes (PROM). The current diagnosis of PROM and preterm PROM (PPROM) is based on vaginal fluid analysis. The present study investigated the value of serum β-human chorionic gonadotropin (β-hCG) and interleukin-1 (IL-1) levels in diagnosing chorioamnionitis. In total, 150 term-pregnancy patients were included in the prospective study. A total of 50 females had normal pregnancies (control group) and 100 had PROM. One hour before delivery, 3 ml venous blood was collected and analyzed. Fetal membrane and placental tissue underwent histopathological analyses. Of the 100 term-pregnancy females, 56 had PROM and 44 had PROM combined with chorioamnionitis (PROM + C). The serum β-hCG levels for the control, PROM and PROM + C groups were 7,557.86±2,922.06, 636.96±14,379.10 and 50,310.34±22,874.82 IU/l, respectively. The receiver operating characteristic (ROC) for PROM and PROM + C groups (β-hCG ≥23,900.50 IU/l) had a sensitivity of 77.5% and a specificity of 78.6%. The level of IL-1 in the PROM + C group was higher compared to the control and PROM groups (0.58±0.05, 0.12±0.04 and 0.13±0.03 ng/ml, respectively). In conclusion, ROC for the PROM and PROM + C groups (IL-1 ≥0.38 ng/ml) had a sensitivity of 76.5% and a specificity of 72.6%. Therefore, serum β-hCG and IL-1 are potential biomarkers for diagnosing PROM and PROM + C, respectively.

Abstract
BACKGROUND We performed a systematic review and meta-analysis of short- vs long-duration antibiotic regimens for ventilator-associated pneumonia (VAP). METHODS We searched PubMed and Cochrane Central Registry of Controlled Trials. Four randomized controlled trials (RCTs) comparing short (7-8 days) with long (10-15 days) regimens were identified. Primary outcomes included mortality, antibiotic-free days, and clinical and microbiologic relapses. Secondary outcomes included mechanical ventilation-free days, duration of mechanical ventilation, and length of ICU stay. RESULTS All RCTs included mortality data, whereas data on relapse and antibiotic-free days were provided in three and two out of four RCTs, respectively. No difference in mortality was found between the compared arms (fixed effect model [FEM]: OR = 1.20; 95% CI, 0.84-1.72; P = .32). There was an increase in antibiotic-free days in favor of the short-course treatment with a pooled weighted mean difference of 3.40 days (random effects model: 95% CI, 1.43-5.37; P < .001). There was no difference in relapses between the compared arms, although a strong trend to lower relapses in the long-course treatment was observed (FEM: OR = 1.67; 95% CI, 0.99-2.83; P = .06). No difference was found between the two arms regarding the remaining outcomes. Sensitivity analyses yielded similar results. CONCLUSIONS Short-course treatment of VAP was associated with more antibiotic-free days. No difference was found regarding mortality and relapses; however, a strong trend for fewer relapses was observed in favor of the long-course treatment, being mostly driven by one study in which the observed relapses were probably more microbiologic than clinical. Additional research is required to elucidate the issue.

Abstract
Prevention and effective treatment of exacerbations are major objectives in the management of patients with chronic obstructive pulmonary disease (COPD). Antibiotics are mainstay treatment for patients with severe COPD with an acute exacerbation that includes increased sputum purulence and worsening shortness of breath. Although such treatment is associated with clinical benefit, treatment failure and relapse rates may be high, particularly in cases of inadequate antibiotic therapy through incomplete resolution of the initial exacerbation and persistent bacterial infection. These aspects have led to recommendations for a stratified approach to antibiotic therapy based on patient characteristics associated with increased risk factors for failure. Patients at greatest risk for poor outcome (i.e., those with severe COPD) are likely to derive greatest benefit from early treatment with antibiotics. Long-term or intermittent antibiotic treatment has been shown to prevent COPD exacerbations and hospitalizations. These effects may be achieved by reducing bacterial load in the airways in stable state and/or bronchial inflammation. Although systemic antibiotics are likely to remain the core treatment for patients with moderate to severe exacerbated COPD, inhaled antibiotics may represent a more optimal approach for the treatment and prevention of COPD exacerbations in the future. Regardless of the route of administration, further studies are required to evaluate the potential long-term adverse events of antibiotics and the development of bacterial resistance.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major public health problem in India. Although several International guidelines for diagnosis and management of COPD are available, yet there are lot of gaps in recognition and management of COPD in India due to vast differences in availability and affordability of healthcare facilities across the country. The Indian Chest Society (ICS) and the National College of Chest Physicians (NCCP) of India have joined hands to come out with these evidence-based guidelines to help the physicians at all levels of healthcare to diagnose and manage COPD in a scientific manner. Besides the International literature, the Indian studies were specifically analyzed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (a) definitions, epidemiology, and disease burden; (b) disease assessment and diagnosis; (c) pharmacologic management of stable COPD; (d) management of acute exacerbations; and (e) nonpharmacologic and preventive measures. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP). The strength of recommendation was graded as A or B depending upon the level of evidence.

Abstract
This article outlines the management of patients with acute exacerbations of chronic obstructive pulmonary disease (COPD), which are common in the course of chronic COPD and are associated with substantial morbidity. There are numerous guidelines, but literature suggests that there is substantial variation in care in patients with acute exacerbations of COPD. Key components of acute therapy for most patients include oral steroids, antibiotics, nebulizers, oxygen, and early consideration of noninvasive ventilation. Adjuvant components of care include venous thromboembolism prophylaxis, appropriate immunizations, counseling for smoking cessation, and consideration of pulmonary rehabilitation.

Abstract
Acute bronchitis is a disease characterized by inflammation of the large airways within the lung accompanied by a cough lasting from 1 to 3 weeks. The inflammation occurs as a result of an airway infection or environmental trigger, with viral infections accounting for an estimated 89% to 95% of cases. Symptomatic treatment of cough is primarily required for patients, though in most cases the condition is self-limiting. Therapy consists of both nonpharmacological and pharmacological options to include antibiotics and antivirals, antitussive agents, protussive agents, and beta-2-agonists. This article reviews the treatment options for acute bronchitis and recommends criteria for use.

Abstract
Chronic bronchitis (CB) is a critical component of chronic obstructive pulmonary disease (COPD). Emphysema, reversible airway disease and bronchiectasis also contribute to COPD. Elderly patients are at increased risk for COPD and its components - emphysema, CB and bronchiectasis. In addition, older patients are at increased risk for resistant organisms during episodes of acute exacerbation of CB (AECB). These organisms include the more common bacteria implicated in AECB, such as Haemophilus influenzae, Moraxella catarrhalis and Streptococcus pneumoniae, and less common nonenteric, Gram-negative organisms such as Pseudomonas aeruginosa. Risk-stratified antibiotic treatment guidelines for AECB appear to be useful, although they have not been prospectively validated for the general CB population, and especially not in the elderly CB population. Many of the AECB treatment guidelines that are stratified based on risk factors have recommended that the oral respiratory fluoroquinolone antibiotics (gemifloxacin, levofloxacin and moxifloxacin) play a second-line but pivotal role, particularly in patients who have failed initial antibiotic treatment for simple CB or as initial treatment for complicated CB.

Abstract
A multi-national working group on antibiotic stewardship, from the International Society of Chemotherapy, put together ten recommendations to physicians prescribing antibiotics to outpatients. These recommendations are: (1) use antibiotics only when needed; teach the patient how to manage symptoms of non-bacterial infections; (2) select the adequate ATB; precise targeting is better than shotgun therapy; (3) consider pharmacokinetics and pharmacodynamics when selecting an ATB; use the shortest ATB course that has proven clinical efficacy; (4) encourage patients' compliance; (5) use antibiotic combinations only in specific situations; (6) avoid low quality and sub-standard drugs; prevent prescription changes at the drugstore; (7) discourage self-prescription; (8) follow only evidence-based guidelines; beware those sponsored by drug companies; (9) rely (rationally) upon the clinical microbiology lab; and (10) prescribe ATB empirically - but intelligently; know local susceptibility trends, and also surveillance limitations.

Abstract
BACKGROUND Macrolides have long been recognised to exert immunomodulary and anti-inflammatory actions. They are able to suppress the "cytokine storm" of inflammation and to confer an additional clinical benefit through their immunomodulatory properties. METHODS A search of electronic journal articles was performed using combinations of the following keywords: macrolides, COPD, asthma, bronchitis, bronchiolitis obliterans, cystic fibrosis, immunomodulation, anti-inflammatory effect, diabetes, side effects and systemic diseases. RESULTS Macrolide effects are time- and dose-dependent, and the mechanisms underlying these effects remain incompletely understood. Both in vitro and in vivo studies have provided ample evidence of their immunomodulary and anti-inflammatory actions. Importantly, this class of antibiotics is efficacious with respect to controlling exacerbations of underlying respiratory problems, such as cystic fibrosis, asthma, bronchiectasis, panbrochiolitis and cryptogenic organising pneumonia. Macrolides have also been reported to reduce airway hyper-responsiveness and improve pulmonary function. CONCLUSION This review provides an overview on the properties of macrolides (erythromycin, clarithromycin, roxithromycin, azithromycin), their efficacy in various respiratory diseases and their adverse effects.

Abstract
It is estimated that 50-70% of acute exacerbations of chronic bronchitis (AECB) are caused by bacterial infections. Appropriate selection of antimicrobials may lead to better outcomes and reduced healthcare costs. Respiratory fluoroquinolones (moxifloxacin, levofloxacin and gemifloxacin) have a broad spectrum of activity against most AECB-causing pathogens and are used as first-line treatment in patients with comorbidity, severe airway obstruction or recurrent exacerbations. We review studies, identified through a MEDLINE search, that compared clinical efficacy and speed of recovery for short-course (≤ 5 days) fluoroquinolone therapy with commonly prescribed standard therapy (≥ 7 days). Among 177 studies reporting the use of fluoroquinolones for AECB treatment, 23 used a short-course regimen, shown to be at least as effective as standard therapy of 7 or more days duration. Furthermore, evidence suggests that short-course therapy offers faster resolution of symptoms, faster rate of recovery, fewer relapses, fewer and shorter hospitalizations, and longer time between recurrences.

Abstract
Cystic fibrosis (CF) is a complex multisystemic disease requiring specialized care. It is characterized by progressive pulmonary decline, with intermittent worsening of lung function, often called pulmonary exacerbations. Eighty-five percent of all deaths from CF are a result of pulmonary disease, and pulmonary exacerbations are associated with decline in lung function. Treating pulmonary exacerbations requires a multifaceted approach and includes a multidisciplinary team composed of a physician, nurse, respiratory therapist, physical therapist, and nutritionist. Recently, the Cystic Fibrosis Foundation published guidelines addressing the comprehensive treatment of pulmonary exacerbations. This article outlines the treatment goals established by these guidelines, including the evaluation and treatment of comorbid conditions (eg, CF-related diabetes) and serious complications associated with CF exacerbations (eg, pneumothorax). Proper treatment of pulmonary exacerbations in CF patients will continue to improve their health and quality of life.

Abstract
Chronic obstructive pulmonary disease (COPD) remains a major cause of morbidity and mortality worldwide. COPD is especially prevalent in the elderly, affecting 25% of those aged>or=75 years. The course of the disease in the elderly is often complicated by co-morbid conditions, and its management is complicated by drug-drug interactions. Exacerbations of COPD increase rates of hospitalization and mortality and decrease quality of life. Exacerbations are marked by an increase from baseline in dyspnoea, sputum volume and sputum purulence. Approximately 50% of acute exacerbations of symptoms in COPD are caused by non-typeable Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae and Pseudomonas aeruginosa. Stratification of exacerbations based on severity of symptoms and signs, and severity of underlying COPD, is useful in selecting patients likely to benefit from antibacterial therapy. Patients who are hospitalized with exacerbations, those who have all three symptoms (increased dyspnoea, sputum volume and sputum purulence), and those with severe underlying COPD and exacerbations benefit most from antibacterials. Antibacterial susceptibility patterns among the bacterial pathogens are evolving, and knowledge of local susceptibility patterns is useful in antibacterial selection. Penicillin, amoxicillin, cotrimoxazole (trimethoprim/sulfamethoxazole) and doxycycline should not be used as an initial antibacterial because of resistance patterns. We recommend second-/third-generation cephalosporins, amoxicillin/clavulanic acid, azithromycin and respiratory fluoroquinolones as initial choices. In patients at risk of colonization by, and infection as a result of, P. aeruginosa, ciprofloxacin, levofloxacin or an advanced penicillin/penicillinase combination effective against this species should be used. Drug-drug interactions should be considered in antibacterial choice. The goals of antibacterial therapy for exacerbations of COPD are the prevention of complications such as respiratory failure and death, and the reduction of treatment failures. The role of pathogenic bacteria in progression of stable COPD and the use of prophylactic antibacterials in stable COPD are under investigation. Currently available evidence does not support routine clinical use of prophylactic antibacterials in stable COPD. In conclusion, pathogenic bacteria cause a significant proportion of acute exacerbations of COPD. Use of antibacterials, based on current susceptibility patterns, is beneficial in patients with severe COPD experiencing exacerbations and in patients with severe exacerbations.

Abstract
Acute exacerbations of chronic bronchitis (AECB) are a major contributor to morbidity and mortality in patients with chronic obstructive pulmonary disease, accounting for more than 16 million physician office visits and over 500,000 hospitalizations in the USA each year. Antimicrobials have been recognized by clinical guidelines as an important component in the management of AECB with a bacterial etiology. The challenge of identifying patients most likely to benefit from antimicrobial therapy is difficult in the clinical setting. However, appropriate risk stratification of patients, and the use of antimicrobials within the correct spectrum and for a suitable duration, can improve clinical outcomes while minimizing induction of antimicrobial resistance. With an improved design in pharmacologic and clinical studies, differences can be appreciated among the various antimicrobial agents available to treat AECB. Factors to be considered in antimicrobial agent selection include local tissue penetration, effects on bacteriological eradication, duration of therapy, speed of resolution and prevention or delay of recurrences.

Abstract
The syndrome of chronic obstructive pulmonary disease (COPD) consists of chronic bronchitis (CB), bronchiectasis, emphysema, and reversible airway disease that combine uniquely in an individual patient. Older patients are at risk for COPD and its components—emphysema, CB, and bronchiectasis. Bacterial and viral infections play a role in acute exacerbations of COPD (AECOPD) and in acute exacerbations of CB (AECB) without features of COPD. Older patients are at risk for resistant bacterial organisms during their episodes of AECOPD and AECB. Organisms include the more‐common bacteria implicated in AECOPD/AECB such as Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae. Less‐common nonenteric, gram‐negative organisms including Pseudomonas aeruginosa, gram‐positive organisms including Staphylococcus aureus, and strains of nontuberculosis Mycobacteria are more often seen in AECOPD/AECB episodes involving elderly patients with frequent episodes of CB or those with bronchiectasis. Risk‐stratified antibiotic treatment guidelines appear useful for purulent episodes of AECOPD and episodes of AECB. These guidelines have not been prospectively validated for the general population and especially not for the elderly population. Using a risk‐stratification approach for elderly patients, first‐line antibiotics (e.g., amoxicillin, ampicillin, pivampicillin, trimethoprim/sulfamethoxazole, and doxycycline), with a more‐limited spectrum of antibacterial coverage, are used in patients who are likely to have a low probability of resistant organisms during AECOPD/AECB. Second‐line antibiotics (e.g., amoxicillin/clavulanic acid, second‐ or third‐generation cephalosporins, and respiratory fluoroquinolones) with a broader spectrum of coverage are reserved for patients with significant risk factors for resistant organisms and those who have failed initial antibiotic treatment.

Abstract
The natural history of cystic fibrosis lung disease is one of chronic progression with intermittent episodes of acute worsening of symptoms frequently called acute pulmonary exacerbations These exacerbations typically warrant medical intervention. It is important that appropriate therapies are recommended on the basis of available evidence of efficacy and safety. The Cystic Fibrosis Foundation therefore established a committee to define the key questions related to pulmonary exacerbations, review the clinical evidence using an evidence-based methodology, and provide recommendations to clinicians. It is hoped that these guidelines will be helpful to clinicians in the treatment of individuals with cystic fibrosis.

Abstract
BACKGROUND Controversies persist regarding the optimal management of patients with acute exacerbations of chronic bronchitis (AECB). OBJECTIVE To evaluate the available evidence on relevant issues, namely the need for administering antimicrobials in patients with AECB, the identification of the subgroup of patients with AECB needing antibiotics, the antimicrobial regimen of choice and its optimal duration, the existence of new agents, and the value of non-antimicrobial regimens for AECB. METHODS Data from various sources of evidence, including recent relevant meta-analyses, were appraised. CONCLUSION Administration of antimicrobial agents, combined with bronchodilators and systemic corticosteroids, is warranted in approximately half of AECBs (i.e., in bacterial exacerbations) to achieve a survival benefit. Simple clinical parameters, mainly sputum purulence, and biomarkers, such as procalcitonin, are useful in identifying patients requiring antibiotics. Advanced antibiotics (quinolones, macrolides, or amoxicillin/clavulanic acid) are more effective than 'old' antibiotics in AECB; regimens of short duration (for 5 days) are preferred. There is no difference between several classes of advanced antibiotics regarding their short-term effectiveness; however, quinolones are associated with better long-term outcomes than macrolides. Newer quinolones and new formulations of macrolides enrich clinicians' armamentarium against AECB.
