Clinical and bacteriologic efficacy of telithromycin in patients with bacteremic community-acquired pneumonia.

This retrospective analysis was performed to determine the clinical and bacteriologic efficacy of the ketolide antibacterial telithromycin in patients with community-acquired pneumonia (CAP) with pneumococcal bacteremia. Patients 13 years old with radiologically confirmed CAP and a positive blood culture for Streptococcus pneumoniae at screening were analyzed from eight multicenter Phase III/IV clinical trials. In four open-label, non-comparative studies, patients received telithromycin 800 mg once daily for 7-10 days. In four randomized, controlled, double-blind, comparative studies, patients received telithromycin 800 mg once daily for 5-10 days or a comparator antimicrobial (amoxicillin 1000 mg three times daily, clarithromycin 500 mg twice daily, or trovafloxacin 200 mg once daily) for 7-10 days. In total, 118 patients (telithromycin, 94/1061 [8.9%]; comparator, 24/244 [9.8%]) had documented pneumococcal bacteremia. Those who were treated with telithromycin achieved a clinical cure rate of 90.2% (74/82, per-protocol population); S. pneumoniae was eradicated in 77/82 (93.9%) bacteremic patients who received telithromycin and 15/19 (78.9%) comparator-treated patients. Clinical cure was also observed among telithromycin-treated bacteremic patients who were infected with penicillin- or erythromycin-resistant strains of S. pneumoniae (5/7 and 8/10, respectively). In conclusion, telithromycin achieves high clinical and bacteriologic cure rates in CAP patients with pneumococcal bacteremia.

Efficacy of telithromycin in community-acquired pneumonia caused by pneumococci with reduced susceptibility to penicillin and/or erythromycin.

BACKGROUND: The efficacy of oral telithromycin was assessed in patients with community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae with reduced susceptibility to penicillin and/or erythromycin. METHODS: Patients with CAP who had received telithromycin 800 mg once daily for 5 or 7-10 days (n = 2,289) in eight phase III clinical trials, or telithromycin 800 mg once daily for 7 days (n = 50) in a phase II study were included in this pooled analysis. Patients with S. pneumoniae as the cause of infection were identified, with particular focus on those infected with strains with reduced susceptibility to penicillin (intermediate, minimal inhibitory concentration (MIC) 0.12-1.0 mg/l; resistant, MIC >or=2.0 mg/l) and/or resistance to erythromycin (MIC >or=1.0 mg/l). Per-protocol clinical and bacteriological outcomes were assessed 7-14 days post-therapy in the phase III studies, and at 7-21 days post-therapy or at the end of therapy in the phase II study. RESULTS: Of the 327 telithromycin-treated patients with S. pneumoniae infection, 61 (19%) were infected with strains with reduced susceptibility to penicillin and/or erythromycin. Clinical cure and bacterial eradication rates in these patients were 91.8% (56/61) and 93.4% (57/61), respectively. Corresponding clinical cure and bacterial eradication rates overall for all isolates of pneumococci were 94.5% (309/327) and 96.0% (314/327), respectively. All isolates with reduced susceptibility to penicillin and/or erythromycin were susceptible to telithromycin (MIC <or=1.0 mg/l). CONCLUSION: These results indicate that telithromycin is an effective oral antibacterial for the treatment of CAP caused by pneumococci with reduced susceptibility to penicillin and/or erythromycin.

Efficacy of moxifloxacin for treatment of penicillin-, macrolide- and multidrug-resistant Streptococcus pneumoniae in community-acquired pneumonia.

This pooled analysis of six prospective, multicentre trials aimed to determine the efficacy of moxifloxacin in community-acquired pneumonia (CAP) due to penicillin-, macrolide- and multidrug-resistant Streptococcus pneumoniae (MDRSP). At a central laboratory, isolates were identified and antimicrobial susceptibility determined (microbroth dilution). MDRSP was defined as resistance > or =3 drug classes. Patients received oral or sequential intravenous/oral 400 mg moxifloxacin once daily for 7-14 days. The primary endpoint was clinical success at test-of-cure for efficacy-valid patients with proven pretherapy S. pneumoniae infection. Of 140 S. pneumoniae isolated (112 respiratory, 28 blood), 23 (16.4%) were penicillin resistant, 26 (18.6%) macrolide resistant and 31 (22.1%) MDRSP. The moxifloxacin MIC90 was 0.25 microg/ml. Clinical cure with moxifloxacin was 95.4% (125/131) overall, and 100% (21/21) for penicillin-, 95.7% (22/23) for macrolide- and 96.4% (27/28) for multidrug-resistant strains. Moxifloxacin provided excellent clinical and bacteriological cure rates in CAP due to drug-resistant pneumococci.

Telithromycin for the treatment of acute exacerbations of chronic bronchitis.

Pooled data from three randomized, double-blind, multi- centre studies evaluated the efficacy and tolerability of telithromycin 800 mg once daily for 5 days vs. standard comparators (10-day amoxicillin-clavulanate 500/125 mg three times daily, clarithromycin 500 mg or cefuroxime axetil 500 mg twice daily) in the outpatient treatment for acute exacerbations of chronic bronchitis. Per-protocol clinical cure rates at post-therapy/test of cure (days 17-24) were 86.0 and 85.8% for telithromycin and comparators, respectively, and 79.1 and 78.7%, respectively, at late post-therapy (days 31-36). Clinical cure rates were comparable for patients at increased risk, including those of > or =65 years and those with severe infection or significant airway obstruction (telithromycin, > or =77.1%; comparators, > or =75.0%). Telithromycin was well tolerated. Most adverse events considered possibly related to study medication were gastrointestinal and of mild intensity. In conclusion, 5-day telithromycin therapy is as effective and well tolerated as 10-day treatment with standard comparators.

A randomized, double-blind study comparing 5 days oral gemifloxacin with 7 days oral levofloxacin in patients with acute exacerbation of chronic bronchitis.

OBJECTIVE: To demonstrate that 5 days of treatment with a new fluoroquinolone, gemifloxacin, is at least as effective as 7 days of treatment with levofloxacin in adult patients with acute exacerbation of chronic bronchitis (AECB). DESIGN: Randomized, double-blind, double dummy, multicentre, parallel group study SETTING: Sixty different medical centers in US, UK and Germany. MATERIAL AND METHODS: A total of 360 adults (>40 years of age) with AECB were randomly assigned to receive gemifloxacin 320 mg once daily for 5 days or levofloxacin 500mg once daily for 7 days. The primary efficacy parameter was a clinical response at follow-up (Days 14-21). RESULTS: In total, 335/360 patients completed the study (93.1%). Seven patients receiving gemifloxacin withdrew from the study compared to 18 patients receiving levofloxacin; this difference was statistically significant (Fisher's exact test: p=0.02). In the intent-to-treat (ITT) population, the clinical success rate at follow-up (Days 14-21) was 85.2% (155/182) with gemifloxacin and 78.1% (139/178) with levofloxacin. Clinical success rate in the per-protocol (PP) population was 88.2% (134/152) with gemifloxacin and 85.1% (126/148) with levofloxacin. At long-term follow-up (Days 28-35), the clinical success rates in the PP population were 83.7% (123/147) with gemifloxacin and 78.4% (109/139) with levofloxacin. The difference in success rates was 5.26% (95% CI: -3.83, 14.34). CONCLUSION: The clinical efficacy of gemifloxacin 320 mg once daily for 5 days in AECB was at least as good as levofloxacin 500 mg once daily for 7 days. Fewer withdrawals and superior clinical efficacy at long-term follow-up were also seen with gemifloxacin.

Telithromycin in the treatment of community-acquired pneumonia: a pooled analysis.

The efficacy of telithromycin has been assessed in six Phase III studies involving adults with mild to moderate community-acquired pneumonia (CAP) with a degree of severity compatible with oral therapy. Patients received telithromycin 800 mg once daily for 7-10 days in three open-label studies (n=870) and three randomized, double-blind, comparator-controlled studies (n=503). Comparator antibacterials were amoxicillin 1000 mg three-times daily, clarithromycin 500 mg twice daily and trovafloxacin 200 mg once daily. Clinical and bacteriological outcomes were assessed 7-14 days post-therapy. Among telithromycin-treated patients, per-protocol clinical cure rates were 93.1 and 91.0% for the open-label and comparative studies, respectively. Telithromycin treatment was as effective as the comparator agents. High eradication and clinical cure rates were observed for infections caused by key pathogens: Streptococcus pneumoniae including isolates resistant to penicillin G and/or erythromycin A (95.4%), Haemophilus influenzae (89.5%) and Moraxella catarrhalis (90%). Telithromycin was also highly effective in patients with infections caused by atypical and/or intracellular pathogens and those at increased risk of morbidity. Telithromycin was generally well tolerated. Telithromycin 800 mg once daily for 7-10 days offers a convenient and well-tolerated first-line oral therapy for the empirical treatment of mild to moderate CAP.

Comparison of 5-day, short-course gatifloxacin therapy with 7-day gatifloxacin therapy and 10-day clarithromycin therapy for acute exacerbation of chronic bronchitis.

BACKGROUND: The ideal duration of antibiotic therapy for acute exacerbation of chronic bronchitis (AECB) remains controversial. OBJECTIVE: This study compared short-course, 5-day gatifloxacin treatment with standard 10-day clarithromycin treatment in patients with AECB; 7-day gatifloxacin therapy was a secondary comparator. METHODS: This was a multicenter, prospective, randomized, double-blind study in which adult outpatients with AECB were randomized to 1 of 3 treatment groups: 5 days of gatifloxacin, 7 days of gatifloxacin, or 10 days of clarithromycin. Clinical cure and microbiologic eradication rates were determined 7 to 14 days after the completion of antibiotic treatment. RESULTS: A total of 527 patients with AECB were enrolled and treated with study drug (174, gatifloxacin 5-day; 175, gatifloxacin 7-day; 178, clarithromycin 10-day). Most patients (82%) had type 1 (severe) exacerbations, and a bacterial pathogen was isolated from pretreatmer, sputum samples in 59% of patients. The overall clinical cure rates among clinically evaluable patients were comparable between groups: 89% (135/151 patients) in the gatifloxacin 5-day group; 88% (136/154) in the gatifloxacin 7-day group; and 89% (145/163) in the clarithromycin 10-day group. The 95% CIs for the differences in response rates were -6.1 to 7.0 for gatifloxacin 5-day versus clarithromycin, -8.9 to 5.0 for gatifloxacin 7-day versus clarithromycin, and -5.5 to 8.0 for gatifloxacin 5-day versus 7-day. These observations did not appear to be affected by use of corticosteroids or smoking status, type of exacerbation, or duration of current episode. The microbiologic eradication rate among microbiologically evaluable pathogens was >90% in all treatment groups. No clinically meaningful differences were noted in the incidence of drug-related adverse events. CONCLUSION: Short-course, 5-day gatifloxacin therapy in patients with AECB resulted in clinical cure and microbiologic eradication rates comparable to those of standard 7- and 10-day therapies.

Project LID (lower infant deaths). Lessons learned from a local infant mortality review project.

Project LID (Lower Infant Deaths) is an infant mortality review project conducted by the Minneapolis Department of Health and Family Support and the Saint Paul-Ramsey County Department of Public Health. Infant death occurs when a live-born infant dies before age 1. Multidisciplinary teams reviewed 112 infant-mother cases involving infant death using vital and medical records. Open-ended maternal interviews were conducted for approximately half of the cases. This combination of quantitative and qualitative data provided insights into the contributing social, medical, and environmental factors experienced by some families in Hennepin and Ramsey counties. Case review teams developed recommendations to address factors identified in each case. Recommendations are directed to health care providers, professional societies, health systems, government organizations, policymakers, and community- and school-based organizations. This article describes findings from the project and presents recommendations for Minnesota physicians with practices in obstetrics, family medicine, and pediatrics.

The in-vitro activity of HMR 3647, a new ketolide antimicrobial agent.

The in-vitro activity of HMR 3647, a novel ketolide, was investigated in comparison with those of erythromycin A, roxithromycin, clarithromycin (14-membered ring macrolides), amoxycillin-clavulanate and ciprofloxacin against 719 recent clinical Gram-positive, Gram-negative and anaerobic isolates and type cultures. HMR 3647 generally demonstrated greater activity than the other compounds with MIC90s of < or =0.5 mg/L, except for Staphylococcus epidermidis (MIC90 > 128 mg/L), Haemophilus influenzae (MIC90 = 2 mg/L), Enterococcus faecalis (MIC90 = 2 mg/L), Enterococcus faecium (MIC90 = 1 mg/L) and the anaerobes, Bacteroides fragilis (MIC90 = 2 mg/L) and Clostridium difficile (MIC90 = 1 mg/L). In general, an increase in the size of the inoculum from 10(4) to 10(6) cfu on selected strains had little effect on the MICs of HMR 3647. Additionally, the in-vitro activity of HMR 3647 was not affected by the presence of either 20 or 70% (v/v) human serum. The antichlamydial activity of HMR 3647 was generally greater than that of commonly used antichlamydial antimicrobials.

Eye movements and blinks: their relationship to higher cognitive processes.

Information about the timing of spontaneous eye blinks was abstracted while subjects performed a detection and identification task. We found blinks to be time-locked to saccadic eye movements involved in the identification of peripherally presented stimuli. The larger the required eye movement, the greater the likelihood of blink occurrence. Blink latencies were found to be significantly shorter for centrally, as compared to peripherally presented stimuli, and blinks were more likely to be associated with eye movement returning gaze to a central location than with movements associated with the identification of peripherally presented information. Thus, we conclude that the spontaneous or endogenous eye blink is triggered by aspects of information processing, and that blink latencies can be used as one tool for evaluating the level of complexity of such processing under a wide variety of task demands.

Pathologic flail chest complicating multiple myeloma.

Pathologic flail chest complicated the initial presentation of multiple myeloma in two patients. Both had severe hypercalcemia and diffuse bone disease. Atelectasis and pulmonary edema preceded the appearance of flail chest in one patient; atelectasis complicated the flail chest in the second patient and increased the severity of the flail. Both were treated with radiotherapy and chemotherapy. However, delay in stabilizing the first patient's chest wall with positive airway pressure was followed by extension of the flail chest and irreversible respiratory failure. On the other hand, prolonged stabilization of the chest wall in the second patient until a chemotherapy-induced remission occurred was associated with resolution of the flail chest.
