Abstract
OBJECTIVE Most exacerbations are mild to moderate, and antibiotic treatment for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is recommended for patients with severe exacerbations or severe underlying chronic obstructive pulmonary disease (COPD). Therefore, we aimed to investigate the patient factors that are associated with the prescription of antibiotics for inappropriate indication in AECOPD. MATERIAL AND METHODS This study was an observational cross-sectional study conducted in an outpatient clinic. The patients diagnosed with AECOPD and prescribed an antibiotic by a pulmonary physician were enrolled in the study. These prescriptions were documented by the pharmacist who asked the patient about the three cardinal symptoms. Appropriate and inappropriate prescription groups were defined by the types of exacerbations, as defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) COPD report. RESULTS There were 138 patients, predominantly male (83%), with a mean age of 64 (±9) years. A total of 64% of the prescriptions were appropriate; however, there were 50 (36%) patients with inappropriate antibiotic prescription according to the mentioned criteria. When we compared the patient factors between the appropriate and inappropriate antibiotic prescriptions, there was no statistically significant difference in terms of age, Forced expiratory volume in first second % (FEV1%) predicted, FEV1 ml, forced vital capacity (FVC) ml, FEV1/FVC, and amount (packs/year) of smoking (p>0.05 for all parameters). FVC% was statistically significantly lower in the appropriate antibiotic prescription group compared with that in the inappropriate antibiotic prescription group (p=0.049). CONCLUSION This study shows that most pulmonary physicians have a tendency to prescribe antibiotics for AECOPD according to the defined GOLD criteria. However, some of the physicians also prefer to prescribe antibiotics self-directedly, irrespective of the GOLD criteria. A physician-based questionnaire can be completed for future studies to define the underlying reasons for antibiotic prescription demands for cases of mild AECOPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by frequent exacerbations. PURPOSE To evaluate the comparative effectiveness and adverse events (AEs) of pharmacologic interventions for adults with exacerbation of COPD. DATA SOURCES English-language searches of several bibliographic sources from database inception to 2 January 2019. STUDY SELECTION 68 randomized controlled trials that enrolled adults with exacerbation of COPD treated in out- or inpatient settings other than intensive care and compared pharmacologic therapies with placebo, "usual care," or other pharmacologic interventions. DATA EXTRACTION Two reviewers independently extracted data and rated study quality and strength of evidence (SOE). DATA SYNTHESIS Compared with placebo or management without antibiotics, antibiotics given for 3 to 14 days were associated with increased exacerbation resolution at the end of the intervention (odds ratio [OR], 2.03 [95% CI, 1.47 to 2.80]; moderate SOE) and less treatment failure at the end of the intervention (OR, 0.54 [CI, 0.34 to 0.86]; moderate SOE), independent of severity of exacerbations in out- and inpatients. Compared with placebo in out- and inpatients, systemic corticosteroids given for 9 to 56 days were associated with less treatment failure at the end of the intervention (OR, 0.01 [CI, 0.00 to 0.13]; low SOE) but also with a higher number of total and endocrine-related AEs. Compared with placebo or usual care in inpatients, other pharmacologic interventions (aminophyllines, magnesium sulfate, anti-inflammatory agents, inhaled corticosteroids, and short-acting bronchodilators) had insufficient evidence, showing either no or inconclusive effects (with the exception of the mucolytic erdosteine) or improvement only in lung function. LIMITATION Scant evidence for many interventions; several studies had unclear or high risk of bias and inadequate reporting of AEs. CONCLUSION Antibiotics and systemic corticosteroids reduce treatment failure in adults with mild to severe exacerbation of COPD. PRIMARY FUNDING SOURCE Agency for Healthcare Research and Quality.

Abstract
Over the past several years, the significance of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in patients with chronic airflow obstruction has become increasingly apparent due to the impact these episodes have on the natural history of disease. It is now known that frequent AECOPD can adversely affect a patient's health-related quality of life and short- and long-term pulmonary function. The economic burden of these episodes is also substantial. AECOPDs represent a local and systemic inflammatory response to both infectious and noninfectious stimuli, but the majority of episodes are likely related to bacterial or viral pathogens. Patients with purulent sputum and multiple symptoms are the most likely to benefit from treatment with antibiotics. Antibiotic choice should be tailored to the individual patient, taking into account the severity of the episode and host factors which might increase the likelihood of treatment failure. Current evidence suggests that therapeutic goals not only include resolution of the acute episode, but also prolonging the time to the next event. In the future, preventing exacerbations will likely become increasingly accepted as an additional therapeutic goal in chronic obstructive pulmonary disease patients.

Abstract
This article reviews available data on the drug therapy armamentarium for the acute exacerbation of chronic obstructive pulmonary disease (COPD). Summaries of studies and therapeutic issues for bronchodilators, antibiotic therapy, corticosteroid use, and a few miscellaneous agents are presented. Many controversies exist in the criteria defining the acute exacerbation, in defining appropriate outcome parameters for assessment, and, consequently, in developing specific consistent recommendations for drug therapy. Five published guidelines assist the clinician in therapeutic drug management of the acute exacerbation of COPD, and each differs in its recommendations for drug therapy prescription. The article includes synopses for drug therapy recommendations from the guidelines.

Abstract
Exacerbations of COPD, which include combinations of dyspnea, cough, wheezing, increased sputum production (and a change in its color to green or yellow), are common. The role of bacterial infection in causing these episodes and the value of antibiotic therapy for them are debated. An assessment of the microbiological studies indicates that conventional bacterial respiratory pathogens, such as Streptococcus pneumoniae and Haemophilus influenzae, are absent in about 50% of attacks. The frequency of isolating these organisms, which often colonize the bronchi of patients in stable condition, does not seem to increase during exacerbations, and their density typically remains unchanged. Serologic studies generally fail to show rises in antibody titers to H influenzae; the only report available demonstrates none to Haemophilus parainfluenzae; and the sole investigation of S pneumoniae is inconclusive. Trials with vaccines against S pneumoniae and H influenzae show no clear benefit in reducing exacerbations. The histologic findings of bronchial biopsies and cytologic studies of sputum show predominantly increased eosinophils, rather than neutrophils, contrary to what is expected with bacterial infections. The randomized, placebo-controlled trials generally show no benefit for antibiotics, but most have studied few patients. A meta-analysis of these demonstrated no clinically significant advantage to antimicrobial therapy. The largest trials suggest that antibiotics confer no advantage for mild episodes; with more severe attacks, in which patients should receive systemic corticosteroids, the addition of antimicrobial therapy is probably not helpful.

Abstract
OBJECTIVE This paper describes the rationale for choosing cefaclor for the management of respiratory tract infections. BACKGROUND Since 1979, cefaclor has established a record of efficacy in the management of respiratory tract infections. Factors contributing to the efficacy and tolerability of this drug include its molecular stability, activity against the most prevalent gram-positive and gram-negative respiratory tract pathogens, rapid absorption, >90% bioavailability, and good penetration into respiratory mucosa. After 2 decades of widespread use, this agent remains clinically effective in patients with respiratory tract infections, making it competitive with other cephalosporins and with macrolides and fluoroquinolones, including many newer agents used for respiratory tract infections. Cefaclor extended-release tablets, the newest formulation, retain the positive efficacy and tolerability attributes of immediate-release cefaclor, varying mainly in the rate of dissolution. The approved indications for extended-release cefaclor include bacterial bronchitis, pharyngitis, and skin infections. METHODS A MEDLINE search showed that the few adverse effects related to therapy with cefaclor are usually minor and transient and that drug-drug interactions involving cefaclor are rare. CONCLUSIONS Multiple clinical trials have shown that extended-release cefaclor in 375-mg and 500-mg doses BID demonstrates tolerability and efficacy comparable to those of immediate-release cefaclor 250 mg TID. Extended-release cefaclor is indicated for BID dosing, which should encourage greater compliance.

Abstract
COPD is the fifth leading cause of death in the United States, and acute respiratory infections account for a significant proportion of all primary care visits. Approximately one half of all exacerbations of COPD can be attributed to bacterial infection, and antibiotic therapy has been demonstrated to improve clinical outcomes and hasten clinical and physiologic recovery. The major pathogen continues to be Haemophilus influenzae, and resistance to beta-lactam antibiotics such as ampicillin can be expected in 20 to 40% of isolated strains. Certain high-risk patients, in whom the cost of clinical treatment failure is high, can be identified by simple clinical criteria. Patients with significant cardiopulmonary comorbidity, frequent purulent exacerbations of COPD, advanced age, generalized debility, malnutrition, chronic corticosteroid administration, long duration of COPD, and severe underlying lung function tend to fail therapy with older drugs, such as ampicillin, and early relapse can be expected. Treatment directed toward resistant pathogens with potent bactericidal drugs may be expected to lead to improved clinical outcomes and overall lower costs, particularly if hospital admissions and respiratory failure can be prevented. Future studies examining the role of antibiotics should enroll these high-risk patients to determine if new therapies have significant clinical, quality-of-life, and economic advantages over older agents.

Abstract
Acute bronchitis and acute exacerbations of chronic bronchitis, common illnesses encountered by general and family physicians, account for approximately 14 million physician visits per year. The pattern of antibiotic prescribing for these infections varies from country to country, but there is no clear rationale for these antimicrobial choices. A recent meta-analysis of all randomized, placebo-controlled trials of patients treated with antibiotics for acute exacerbations of chronic bronchitis concluded that a small but statistically significant improvement could be expected in antibiotic-treated patients. Haemophilus influenzae is the most commonly isolated organism from sputum in patients with acute exacerbations of chronic obstructive lung disease but other Haemophilus species, Streptococcus pneumoniae, and Moraxella catarrhalis may also be found. High-risk patients can be defined as being elderly, with significant impairment of lung function, having poor performance status with other comorbid conditions, having frequent exacerbations, and often requiring oral corticosteroid medication. Well-defined clinical trials measure efficacy of a drug but not the effectiveness in a real world situation. Future studies of new antimicrobials should examine their efficacy in patients with an increased risk of true bacterial infection.

Abstract
A new controlled-delivery, extended-release 500-mg formulation of cefaclor that is administered twice daily may improve patient compliance compared with the older, immediate-release 250-mg formulation that is administered three times daily. When the extended-release tablet is administered with food, peak plasma cefaclor concentrations are achieved about 2.5 hours after the dose compared with about 1 hour after a dose with the immediate-release capsule. However, the two formulations have an equivalent extent of absorption and equivalent pharmacokinetics after absorption. Cefaclor has retained its excellent in vitro activity against the pathogens most commonly associated with acute exacerbations of chronic bronchitis, namely, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae. Clinical trials show similar efficacy of the two formulations in patients with acute exacerbations of chronic bronchitis caused by these organisms, but for this indication a 7-day regimen may be used with the extended-release 500-mg formulation compared with a 10-day dosing regimen with the 250-mg capsule. The shorter course of treatment with the new formulation may also improve patient compliance.

Abstract
OBJECTIVE To discuss the pharmacokinetics, spectrum of activity, clinical trials, and adverse effects of cefprozil, cefpodoxime proxetil, loracarbef, cefixime, and ceftibuten, an investigational cephalosporin. DATA SOURCES Literature was identified by a MEDLINE search from 1986 to January 1995. STUDY SELECTION Randomized, controlled studies were selected for evaluation; however, uncontrolled studies were included when data were limited for indications approved by the Food and Drug Administration. DATA EXTRACTION Data were evaluated with respect to in vitro activity, study design, clinical and microbiologic outcomes, and adverse drug reactions. DATA SYNTHESIS Cefprozil, cefpodoxime proxetil, loracarbef, cefixime, and cefributen are active in vitro against organisms frequently involved in community-acquired infections such as Streptococcus pneumoniae, Escherichia coli, beta-lactamase-positive or -negative Haemophilus influenzae, and Moraxella catarrhalis. Except for cefixime and ceflibuten, they all are active against methicillin-susceptible Staphylococcus aureus. Even though there were problems in study design (discussed within the text), clinical data demonstrate that these new oral beta-lactam compounds are as efficacious as conventional therapies for a variety of community-acquired infections. CONCLUSIONS Cefprozil, cefpodoxime, cefixime, loracarbef, and ceftibuten demonstrate in vitro activity against the major organisms that cause community-acquired infections. Clinical trials confirm that these agents are as effective as traditional therapies for the management of acute otitis media, pharyngitis/tonsillitis, sinusitis, bronchitis, pneumonia, urinary tract infections, and skin and skin-structure infections. In addition, cefixime and cefpodoxime are effective therapies for uncomplicated gonococcal infections. Selection of a specific agent will be influenced by susceptibility data and safety, as well as issues of compliance and cost.
