amoxicillin-potassium-clavulanate-combination and Pulmonary-Disease--Chronic-Obstructive

Rothia mucilaginosa is a Gram-positive, coagulase-negative, encapsulated, non-spore-forming coccus considered part of the commensal flora of the oral cavity and the upper respiratory tract in humans. Its involvement has been reported in an increasing spectrum of infections, above all among immunocompromised patients. To date, only 11 cases of pneumonia due to Rothia mucilaginosa have been described in the literature. The authors report a case of pneumonia due to Rothia mucilaginosa in a 72-year-old man with laryngeal cancer and review the published cases of pneumonia due to this pathogen.

Changes in sputum microbiology following antibiotic treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), including patterns of bacteriological relapse and superinfection are not well understood. Sputum microbiology at exacerbation is not routinely performed, but pathogen presence and species are determinants of outcomes. Therefore, we determined whether baseline clinical factors could predict the presence of bacterial pathogens at exacerbation. Bacterial eradication at end of treatment (EOT) is associated with clinical resolution of exacerbation. We determined the clinical, microbiological and therapeutic factors that were associated with bacteriological eradication in AECOPD at EOT and in the following 8 weeks.. Sputum bacteriological outcomes (i.e., eradication, persistence, superinfection, reinfection) from AECOPD patients (N = 1352) who were randomized to receive moxifloxacin or amoxicillin/clavulanate in the MAESTRAL study were compared. Independent predictors of bacterial presence in sputum at exacerbation and determinants for bacteriological eradication were analyzed by logistic regression and receiver operating characteristic (ROC) analyses.. Significantly greater bacteriological eradication with moxifloxacin was mainly driven by superior Haemophilus influenzae eradication (P = 0.002, EOT). Baseline clinical factors were a weak predictor of the presence of pathogens in sputum (AUCROC = 0.593). On multivariate analysis, poorer bacterial eradication was associated with antibiotic resistance (P = 0.0001), systemic steroid use (P = 0.0024) and presence of P. aeruginosa (P = 0.0282).. Since clinical prediction of bacterial presence in sputum at AECOPD is poor, sputum microbiological analysis should be considered for guiding antibiotic therapy in moderate-to-severe AECOPD, particularly in those who received concomitant systemic corticosteroids or are at risk for infection with antibiotic-resistant bacteria.

Acute exacerbations represent a significant burden for patients with moderate-to-severe chronic obstructive pulmonary disease. Each exacerbation episode is frequently associated with a lengthy recovery and impaired quality of life. Prognostic factors for outpatients that may predict poor outcome after treatment with antibiotics recommended in the guidelines, are not fully understood. We aimed to identify pretherapy factors predictive of clinical failure in elderly (≥60 years old) outpatients with acute Anthonisen type 1 exacerbations.. NCT00656747.. Based on the moxifloxacin in AECOPDs (acute exacerbations of chronic obstructive pulmonary disease) trial (MAESTRAL) database, this study evaluated pretherapy demographic, clinical, sputum bacteriological factors using multivariate logistic regression analysis, with internal validation by bootstrap replicates, to investigate their possible association with clinical failure at end of therapy (EOT) and 8 weeks posttherapy.. The analyses found that the independent factors predicting clinical failure at EOT were more frequent exacerbations, increased respiratory rate and lower body temperature at exacerbation, treatment with long-acting anticholinergic drugs, and in vitro bacterial resistance to study drug. The independent factors predicting poor outcome at 8 weeks posttherapy included wheezing at preexacerbation, mild or moderate (vs extreme) sleep disturbances, lower body temperature at exacerbation, forced expiratory volume in 1 second <30%, lower body mass index, concomitant systemic corticosteroids for the current exacerbation, maintenance long-acting β2-agonist and long-acting anticholinergic treatments, and positive sputum culture at EOT.. Several bacteriological, historical, treatment-related factors were identified as predictors of early (EOT) and later (8 weeks posttherapy) clinical failure in this older outpatient population with moderate-to-severe chronic obstructive pulmonary disease. These patients should be closely monitored and sputum cultures considered before and after treatment.

This open comparative randomized study of efficacy, safety, and pharmacoeconomic characteristics of hilifox-750 (750 mg daily for 5 days) and amoxiclav 2X (875/125 mg twice daily for 10 days) included 60 patients with chronic obstructive pulmonary disease (COPD). Duration of the study was 6 months. Medians of age and smoking index in the group treated with hilifox-750 were 63.5 yr (59, 67) and 30 packs/yr (15, 60) respectively. The treatment reduced cough, apnea, sputum volume and pyoptysis with comparative rates of normalization of body temperature and peripheral leukocyte counts in both groups. Helifox-750 promoted decrease in coughing and apnea within the first three days of therapy. 28 (93%) and 26 (87%) patients recovered by day 4 of helifox and amoxiclav therapy (F-test p = 0.67). Both drugs showed comparable bacteriological efficacy. They were not different in terms of side effect frequency that were mild, resolved spontaneously and did not require withdrawal of therapy. Helifox had advantages over amoxiclav in that it reduced duration of antibacterial therapy to 5 days and of temporary incapacity to 12 days (vs 14); moreover, it needs to be taken only once daily.

Anthonisen criteria are widely used to guide the use of antibiotics in exacerbations of COPD. We evaluated the best predictors of outcomes in exacerbations of mild to moderate COPD not treated with antibiotics.. We used data from 152 patients of the placebo arm of a randomized trial of amoxicillin/clavulanate for exacerbations of mild to moderate COPD. Clinical response in relation to Anthonisen criteria and point-of-care serum C-reactive protein (CRP) tests (cutoff, 40 mg/L) was assessed with multivariate logistic regression analysis.. Clinical failure without antibiotics was 19.9% compared with 9.5% with amoxicillin/clavulanate (P = .022). The only factors significantly associated with an increased risk of failure without antibiotics were the increase in sputum purulence (OR, 6.1; 95% CI, 1.5-25.0; P = .005) and a CRP concentration ≥ 40 mg/L (OR, 13.4; 95% CI, 4.6-38.8; P < .001). When both factors were present, the probability of failure without antibiotics was 63.7%. The Anthonisen criteria showed an area under the curve of 0.708 (95% CI, 0.616-0.801) for predicting clinical outcome. With the addition of CRP level, the area under the curve rose significantly to 0.842 (95% CI, 0.76-0.924; P < .001).. Among the Anthonisen criteria, only an increase in sputum purulence is a significant predictor of failure without antibiotics. The use of a point-of-care CRP test significantly increases the predictive accuracy of failure. Both of these easy-to-obtain factors may help clinicians to identify patients with exacerbated mild to moderate COPD who can be safely treated without antibiotics in an ambulatory setting..

Bacterial infections causing acute exacerbations of chronic obstructive pulmonary disease (AECOPD) frequently require antibacterial treatment. More evidence is needed to guide antibiotic choice. The Moxifloxacin in Acute Exacerbations of Chronic Bronchitis TriaL (MAESTRAL) was a multiregional, randomised, double-blind non-inferiority outpatient study. Patients were aged ≥ 60 yrs, with an Anthonisen type I exacerbation, a forced expiratory volume in 1 s < 60% predicted and two or more exacerbations in the last year. Following stratification by steroid use patients received moxifloxacin 400 mg p.o. q.d. (5 days) or amoxicillin/clavulanic acid 875/125 mg p.o. b.i.d. (7 days). The primary end-point was clinical failure 8 weeks post-therapy in the per protocol population. Moxifloxacin was noninferior to amoxicillin/clavulanic acid at the primary end-point (111 (20.6%) out of 538, versus 114 (22.0%) out of 518, respectively; 95% CI -5.89-3.83%). In patients with confirmed bacterial AECOPD, moxifloxacin led to significantly lower clinical failure rates than amoxicillin/clavulanic acid (in the intent-to-treat with pathogens, 62 (19.0%) out of 327 versus 85 (25.4%) out of 335, respectively; p=0.016). Confirmed bacterial eradication at end of therapy was associated with higher clinical cure rates at 8 weeks post-therapy overall (p=0.0014) and for moxifloxacin (p=0.003). Patients treated with oral corticosteroids had more severe disease and higher failure rates. The MAESTRAL study showed that moxifloxacin was as effective as amoxicillin/clavulanic acid in the treatment of outpatients with AECOPD. Both therapies were well tolerated.

Antimicrobial therapy remains a controversial issue in nonsevere exacerbations of chronic obstructive pulmonary disease (COPD).. To evaluate the efficacy of antibiotic therapy in moderate exacerbations of mild-to-moderate COPD.. This study involved a multicenter, parallel, double-blind, placebo-controlled, randomized clinical trial. Patients aged 40 years or older, smokers, or ex-smokers of 10 pack-years or more with spirometrically confirmed mild-to-moderate COPD (FEV(1) > 50% predicted and FEV(1)/FVC ratio < 0.7) and diagnosed with an exacerbation were enrolled in the study. The patients were randomized to receive amoxicillin/clavulanate 500/125 mg three times a day or placebo three times a day for 8 days.. The primary outcome measure was clinical cure at end of therapy visit (EOT) at Days 9 to 11. A total of 310 subjects fulfilled all the criteria for efficacy analysis. A total of 117 patients with amoxicillin/clavulanate (74.1%) and 91 with placebo (59.9%) were considered cured at EOT (difference, 14.2%; 95% confidence interval, 3.7-24.3). The median time to the next exacerbation was significantly longer in patients receiving antibiotic compared with placebo (233 d [interquartile range, 110-365] compared with 160 d [interquartile range, 66-365]; P < 0.05). The best C-reactive protein serum cut-off for predicting clinical failure with placebo was 40 mg/L, with an area under the curve of 0.732 (95% confidence interval, 0.614-0.851).. Treatment of ambulatory exacerbations of mild-to-moderate COPD with amoxicillin/clavulanate is more effective and significantly prolongs the time to the next exacerbation compared with placebo.

Antibiotics, along with oral corticosteroids, are standard treatments for acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The ultimate aims of treatment are to minimize the impact of the current exacerbation, and by ensuring complete resolution, reduce the risk of relapse. In the absence of superiority studies of antibiotics in AECOPD, evidence of the relative efficacy of different drugs is lacking, and so it is difficult for physicians to select the most effective antibiotic. This paper describes the protocol and rationale for MAESTRAL (moxifloxacin in AECBs [acute exacerbation of chronic bronchitis] trial; www.clinicaltrials.gov: NCT00656747), one of the first antibiotic comparator trials designed to show superiority of one antibiotic over another in AECOPD. It is a prospective, multinational, multicenter, randomized, double-blind controlled study of moxifloxacin (400 mg PO [per os] once daily for 5 days) vs. amoxicillin/clavulanic acid (875/125 mg PO twice daily for 7 days) in outpatients with COPD and chronic bronchitis suffering from an exacerbation. MAESTRAL uses an innovative primary endpoint of clinical failure: the requirement for additional or alternate treatment for the exacerbation at 8 weeks after the end of antibiotic therapy, powered for superiority. Patients enrolled are those at high-risk of treatment failure, and all are experiencing an Anthonisen type I exacerbation. Patients are stratified according to oral corticosteroid use to control their effect across antibiotic treatment arms. Secondary endpoints include quality of life, symptom assessments and health care resource use.

Amoxycillin/clavulanate is considered first-line treatment for ambulatory exacerbations of COPD. However, narrow-spectrum antibiotics may be as useful for mild to moderate patients.. To compare the clinical efficacy of amoxycillin versus amoxicyllin/clavulanate in exacerbations of COPD in primary care.. A randomized, double-blind, noninferiority clinical trial was carried out in eight primary care centers in Catalonia, Spain. Spirometrically-diagnosed patients older than 40 years with COPD, without criteria of hospitalization and Anthonisen's types I or II exacerbations were included. The main outcome was clinical cure at the end of treatment (EOT) visit on day 10.. A total of 137 patients were enrolled in the study (68 assigned to amoxycillin and 69 to amoxycillin/clavulanate). The mean forced expiratory flow in one second was 61.6% and the mean age was 71.4 years. At EOT, 92.8% of patients in the amoxycillin/clavulanate and 90.9% in the amoxycillin group were considered clinically cured, a statistically non-significant difference. Adverse effects were observed in 11 subjects, 3 in the amoxycillin group and 8 in the amoxycillin/clavulanate group, 2 of whom required a change in treatment.. Amoxycillin was at least as effective clinically and as safe as amoxycilin/ clavulanate in the treatment of acute exacerbations of COPD in mild to moderate patients in primary care.

The optimal duration of antibiotic treatment for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is unknown. This study compared the outcome of treatment for 3 vs. 10 days with amoxycillin-clavulanic acid of hospitalised patients with AECOPD who had improved substantially after initial therapy for 3 days. Between November 2000 and December 2003, 56 patients with AECOPD were enrolled in the study. Unfortunately, because of the low inclusion rate, the trial was discontinued prematurely. Patients were treated with oral or intravenous amoxycillin-clavulanic acid. Patients who showed improvement after 72 h were randomised to receive oral amoxycillin-clavulanic acid 625 mg or placebo, four times daily for 7 days. The primary outcome measure of the study was clinical cure after 3 weeks and 3 months. Of 46 patients included in the final analysis, 21 were in the 3-day treatment group and 25 were in the 10-day treatment group. After 3 weeks, 16 (76%) of 21 patients in the 3-day treatment group were cured, compared with 20 (80%) of 25 in the 10-day treatment group (difference -3.8%; 95% CI -28 to 20). After 3 months, 13 (62%) of 21 patients were cured, compared with 14 (56%) of 25 (difference 5.9%; 95% CI -23 to 34). Microbiological success, symptom recovery, the use of corticosteroids, the duration of oxygen therapy and the length of hospital stay were comparable for both treatment groups. It was concluded that 3-day treatment with amoxycillin-clavulanic acid can be a safe and effective alternative to the standard 10-day treatment for hospitalised patients with AECOPD who have improved after initial therapy for 3 days.

To compare clinical and microbiological efficacy of penicillines and macrolids in patients with exacerbation of chronic bronchitis (CB) basing on long-term follow-up after antibacterial treatment.. Twenty patients with exacerbated CB or chronic obstructive pulmonary disease (COPD) received amoxicillin/clavulanic acid (augmentin) while 20 other patients were given macrolides (sumamed or clacide). Clinical efficacy was assessed by the rate of exacerbation regression and duration of recurrence-free period in the course of 12-month follow-up. Bacteriological examination was conducted 3-5 days, 1 month after the treatment and at recurrent exacerbation.. Patients on augmentin showed faster regression of exacerbation, earlier remission and higher quality of remission than patients on macrolides. Eradication of etiologically significant pathogens on day 3-5 after therapy with augmentin and macrolides was achieved in 92 and 30% patients, respectively, persistence--in 8 and 70%, respectively. Mean duration of remission was 263 +/- 107.1 and 164.9 +/- 112,2 days, respectively. A correlation was found between duration of recurrence-free period and frequency of eradication and persistence of the agents after antibacterial therapy of CB and COPD.. Augmentin promotes a significantly earlier regress of exacerbation symptoms and persistent remission. Eradication potential of augmentin in CB/COPD patients is higher than that of macrolides. Long-term post-exacerbation monitoring (12-month follow-up) discovered that recurrence-free period of augmentin-treated patients is much longer than in patients on macrolides.

To identify risk factors for late recovery and failure after ambulatory treatment of exacerbations of chronic bronchitis (CB) and chronic obstructive pulmonary disease (COPD).. Observational, non-randomised study of risk factors carried out in 2001 and 2002 in Primary Care practices. Patients aged 40 or older diagnosed with an exacerbation of CB or COPD of probable bacterial etiology were included in the study and followed up for 10 days. Patients were treated with amoxicillin plus clavulanic acid (co-amoxiclav) 500-125 mg tds for 10 days, clarithromycin 500 mg bd for 10 days or moxifloxacin 400 mg od for 5 days.. Two hundred and fifty-two general practitioners participated, registering 1147 valid patients. The rate of failure at day 10 was 15.1% without significant differences among the antibiotic treatments. Median time to recovery was 5 days. Factors significantly associated with late recovery (>5 days) on multivariate analysis were: use of long-term oxygen (OR=1.96; 95%CI=1.35-2.85); use of short-acting beta-2 agonists (OR=1.51; 1.17-1.92). The use of moxifloxacin had a "protective" effect against late recovery compared to co-amoxiclav (OR=0.34; 0.26-0.45) and clarithromycin (OR=0.41; 0.31-2.85). Factors associated with therapeutic failure were: previous hospitalisation (OR=1.61; 1.08-2.42); and 2 or more exacerbations the previous year (OR=1.51; 1.04-2.17); criteria of CB had a protective effect against failure (OR=0.53; 0.35-0.79).. There are readily identifiable risk factors for ambulatory treatment failure of exacerbations of CB and COPD. In addition, long-term oxygen therapy and short-acting beta-2 agonists are associated with late recovery, and the use of moxifloxacin compared with co-amoxiclav and clarithromycin is associated with faster recovery of symptoms.

Pristinamycin is a bactericidal antibiotic whose spectrum covers the main respiratory pathogens including S. pneumoniae poorly sensitive to penicillin. It has not yet been evaluated in short course treatment of acute exacerbations of chronic obstructive bronchitis (AECB).. 476 patients suffering from an AECB were randomised to either a short course of pristinamycin, 3 G daily for 4 days, or conventional treatment with co-amoxiclav (AAC) 2G daily for 8 days. The duration of follow-up was 6 months.. The clinical success rate at 21 days was the same in both groups at 87.2% and 87.9%, CI95% [-7.0%, 6.0%], in the protocol population (FEV1<80%). Among the 120 patients in whom a bacterial pathogen was isolated at the time of inclusion a satisfactory bacteriological response was obtained in 84.6% of the PRI patients against 78.2% of the AAC patients. The time to relapse was comparable with a relapse rate of 25% reached in 128 days in the PRI group and 125 days in the AAC group. Treatment related side effects occurred in 9.2% of the PRI group and in 10.6% of the AAC group.. Pristinamycin 3 G daily for 4 days is as effective and well tolerated as co-amoxiclav 2G daily for 8 days in the treatment of AECB.

Intensive Care Unit (ICU) admission for acute exacerbation of chronic obstructive lung disease (COLD) is a major cause of morbidity and mortality in such patients. Although bacterial and/or viral infections are considered as the major precipitating factor, the antibiotic strategy in this setting is unclear. The potential benefit of routine antibiotic therapy in the absence of evidence of overt infection remains controversial, and has not been adequately studied in patients admitted to the ICU. To assess the benefit (or lack thereof) of routine early systemic antibiotic therapy in patients with COLD admitted to the ICU.. This is a multicenter, randomized, double-blind controlled trial, comparing amoxicillin-clavulanic acid administered for 7 days to a placebo. Patients included are those with documented or suspected COLD, exclusive of other bronchial or lung disease, and admitted for acute exacerbation, in the absence of overt sepsis or broncho-pneumonia, and having no other organ failure. Patients recently hospitalized, having received antibiotics for > 24 h, or on long-term steroids will not be included. Co-interventions (bronchodilators, steroids) are controlled for. Patients will be administered the antibiotic or placebo within 24 hours of admission.. A 20% reduction of the duration of clinical symptoms of exacerbation is expected. To this end, 520 patients are planned to be included in 15 centers in a 2-year period. Secondary end-points are the incidence of documented infection (lower respiratory tract or other sites), antibiotic use, the proportion of patients having infection with resistant bacteria, the incidence of endotracheal intubation, the duration of stay and mortality in the ICU and the hospital.

For antibiotic treatment of Acute exacerbations of COPD (AECOPD) the National guidelines in Denmark recommend either first choice amoxicillin 750 mg TID (AMX) or amoxicillin with clavulanic acid 500 mg/125 mg TID (AMC). Addition of clavulanic acid offers a broader spectrum; opposite, AMX alone in a higher dose may offer more time above MIC. The aim of this study was to determine which of these regimens is associated with better outcome.. The Danish Registry of COPD (DrCOPD), a nationwide outpatient COPD registry, was crosslinked with medication data and hospital contacts. The first prescription of AMX or AMC after inclusion in DrCOPD was used as exposure variable. Adjusted Cox proportional hazards models were used to analyze the risk of hospitalization or death (combined) within 30 days and other endpoints.. For the first treatment of AECOPD 12,915 received AMX, and 30,721 patients received AMC. AMX was associated with a decreased risk of pneumonia hospitalization or death (aHR 0.6, 95% CI 0.5-0.7; p < 0.0001) compared to AMC.. In AECOPD, empirically adding clavulanic acid to amoxicillin is not associated with a better outcome; it seems safe for these patients to be treated with amoxicillin alone.

It is commonly recommended that microbiological assessment should accompany the use of antibiotics prone to resistance. We sought to estimate the rate of microbiology testing and compare this to dispensing of the World Health Organization classified "watch" group antibiotics in primary care.. Data from a cohort of older adults (mean age 69 years) were linked to Australian national health insurance (Pharmaceutical Benefits Scheme & Medicare Benefits Schedule) records of community-based antibiotic dispensing and microbiology testing in 2015. Participant characteristics associated with greater watch group antibiotic dispensing and microbiology testing were estimated using adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI) in multivariable zero-inflated negative binomial regression models.. In 2015, among 244,299 participants, there were 63,306 watch group antibiotic prescriptions dispensed and 149,182 microbiology tests conducted; the incidence rate was 0.26 per person-year for watch group antibiotic dispensing and 0.62 for microbiology testing. Of those antibiotic prescriptions, only 19% were accompanied by microbiology testing within - 14 to + 7 days. After adjusting for socio-demographic factors and co-morbidities, individuals with chronic respiratory diseases were more likely to receive watch group antibiotics than those without, e.g. asthma (aIRR:1.59, 95%CI:1.52-1.66) and chronic obstructive pulmonary disease (COPD) (aIRR:2.71, 95%CI:2.48-2.95). However, the rate of microbiology testing was not comparably higher among them (with asthma aIRR:1.03, 95%CI:1.00-1.05; with COPD aIRR:1.00, 95%CI:0.94-1.06).. Priority antibiotics with high resistance risk are commonly dispensed among community-dwelling older adults. The discord between the rate of microbiology testing and antibiotic dispensing in adults with chronic respiratory diseases suggests the potential for excessive empirical prescribing.

Data are needed from outpatient settings to better inform antimicrobial stewardship. In this study, a random sample of outpatient antibiotic prescriptions by primary care providers (PCPs) at our health care system was reviewed and compared to consensus guidelines. Over 12 months, 3,880 acute antibiotic prescriptions were written by 76 PCPs caring for 40,734 patients (median panel, 600 patients; range, 33 to 1,547). PCPs ordered a median of 84 antibiotic prescriptions per 1,000 patients per year. Azithromycin (25.8%), amoxicillin-clavulanate (13.3%), doxycycline (12.4%), amoxicillin (11%), fluoroquinolones (11%), and trimethoprim-sulfamethoxazole (10.6%) were prescribed most commonly. Medical records corresponding to 300 prescriptions from 59 PCPs were analyzed in depth. The most common indications for these prescriptions were acute respiratory tract infection (28.3%), urinary tract infection (23%), skin and soft tissue infection (15.7%), and chronic obstructive pulmonary disease (COPD) exacerbation (6.3%). In 5.7% of cases, no reason for the prescription was listed. No antibiotic was indicated in 49.7% of cases. In 12.3% of cases, an antibiotic was indicated, but the prescribed agent was guideline discordant. In another 14% of cases, a guideline-concordant antibiotic was given for a guideline-discordant duration. Therefore, 76% of reviewed prescriptions were inappropriate. Ciprofloxacin and azithromycin were most likely to be prescribed inappropriately. A non-face-to-face encounter prompted 34% of prescriptions. The condition for which an antibiotic was prescribed was not listed in primary or secondary diagnosis codes in 54.5% of clinic visits. In conclusion, there is an enormous opportunity to reduce inappropriate outpatient antibiotic prescriptions.

The safety and tolerability of nebulized amoxicillin clavulanic acid were determined in patients with stable COPD and during severe exacerbations of COPD. Nine stable COPD patients received doses ranging from 50:10 mg up to 300:60 mg amoxicillin clavulanic acid and eight patients hospitalised for a COPD exacerbation received fixed doses 200/40 mg twice daily. Safety was evaluated by spirometry before and after inhalation. Tolerability was evaluated by questionnaire. Plasma and expectorated sputum samples were assayed for amoxicillin content. Seventeen patients underwent in total 100 nebulizations with amoxicillin clavulanic acid. In this safety and tolerability study no clinically relevant deteriorations in FEV1 were observed. Nebulized amoxicillin clavulanic acid produces sputum concentrations well above the Minimal Inhibiting Concentration of 90% for potential pathogenic micro-organisms, with low concentrations in the central compartment (low systemic exposure). Based on spirometry and reported side effects, inhalation of nebulized amoxicillin clavulanic acid seems to be safe and well tolerated, both in stable patients with COPD as in those experiencing a severe exacerbation. Levels of amoxicillin were adequate.

Acute exacerbations of chronic obstructive pulmonary disease (COPD) are often treated with antibiotics. Theoretically, to be maximally effective, the antibiotic concentration at sites of infection should exceed the minimum inhibitory concentration at which 90% of the growth of potential pathogens is inhibited (MIC90). A previous study showed that most hospitalized COPD patients had sputum amoxicillin concentrations

Exacerbations are a major cause of disability, hospital admissions, and increased healthcare costs in patients with chronic obstructive pulmonary disease (COPD). This study investigated the clinical outcomes of outpatients with moderate to severe exacerbated COPD and their related costs.. An observational study on the outcomes of ambulatory exacerbations of COPD was conducted. The course of the exacerbation was evaluated at a follow-up visit at 4 weeks. A cost analysis that encompassed the use of healthcare resources for treatment of the exacerbation was performed.. A total of 260 patients were included, with a mean age of 68.3 years and a mean FEV1 (% predicted) of 58.9 %. Twenty-two percent of patients had significant cardiovascular comorbidity. The most frequently prescribed antibiotics were moxifloxacin in 137 cases and amoxicillin-clavulanate in 50 cases. The rate of failure at 4 weeks was 12.5 %, with no differences between the two most prescribed antibiotics; however, patients treated with moxifloxacin had symptoms for 1.9 fewer days (P = 0.01). The mean cost of the exacerbation was 344.96 (95 % CI: 48.55-641.78), with 9.6 % of the costs for drugs and 72.9 % for hospital care of patients for whom treatment had failed.. Antibiotic treatment of our population was in compliance with local guidelines. The rate of failure observed in our study was lower than that reported in previous studies; however, the small percentage of patients that required hospital attention generated almost two-thirds of the total costs of the exacerbations.

Amoxicillin is a widely used antibiotic in COPD. Little is known about the transfer of amoxicillin into sputum of COPD patients. The objective was to investigate the relationship between the concentration of amoxicillin in sputum in hospitalized COPD patients and length of hospitalization. To be effective against bacterial pathogens, the amoxicillin concentration in target tissues should be higher than the Minimal Inhibiting Concentration (MIC) of 2 mg/l. Therefore, this was also used as the cut-off value for the amoxicillin concentration in sputum, as a marker for lung tissue concentration. Fifty-two COPD in-patients with an exacerbation, treated with amoxicillin clavulanic acid, were included in this cohort study. Of these patients 7 also had pneumonia. Patients were divided in patients with an amoxicillin sputum concentration ≥ 2 mg/l and < 2 mg/l. Furthermore, inflammation markers in sputum and serum and clinical parameters were obtained. Of the 33 patients with usable sputum, 11 had a concentration in sputum ≥ 2 mg/l. The mean length of hospitalization for patients with concentrations below the MIC90 to common respiratory pathogens was 11.0 days, while for patients with concentrations at or above the MIC90 this was 7.0 days (p = 0.005). COPD patients admitted for an acute exacerbation of COPD, with a sputum concentration of amoxicillin ≥ 2 mg/l had a markedly reduced length of hospitalization compared to patients with a concentration < 2 mg/l. It is worthwhile testing whether individualized treatment based on sputum amoxicillin concentrations of patients during hospitalization for acute exacerbations can effectively reduce hospital stay.

We report the case of a 52-year-old man, ASA 3-4, malnourished, heavy smoker and drinker at the stage of chronic obstructive pulmonary disease and cirrhosis. The postoperative course of a cervical cancer surgery was complicated by a pneumonia with fatal outcome in the intensive care unit. Taking into account the patient's history and surgical requirements, this nosocomial infection did not appear easily preventable. The multiple risk factors and the few preventive measures usable were analyzed. In this context, the media and legal trend to make the doctors responsible for the nosocomial infections should be revised.

Corynebacterium pseudodiphteriticum has been considered a very infrequent respiratory pathogen. We report three cases of pneumonia due to C. pseudodiphteriticum, describing their clinical and microbiological features. There were two patients with pre-existing chronic respiratory disease, one of their with steroidal therapy, and other associated with endotracheal intubation. The diagnostic was made by Gram stain and quantitative cultures from respiratory tract specimens. All patients were cured after treatment with amoxicillin-clavulanate, ceftriaxone and vancomycin respectively. C. pseudodiphteriticum must be consider as a possible causal agent of pneumonia in patients with underlying respiratory disease or endotracheal intubation. Antimicrobial susceptibility testing of C. pseudodiphteriticum may be useful for correct treatment of infected patients, but beta-lactam antibiotics are an appropriate therapeutic option against this bacteria.
