Telithromycin (HMR 3647) is a new ketolide antimicrobial that was developed for the treatment of community-acquired respiratory tract infections. We conducted a randomized, double-blind, multicenter study to compare the clinical efficacy and safety of oral telithromycin, at 800 mg once daily for 5 or 10 days, with that of amoxicillin/clavulanic acid, at 500/125 mg three times daily for 10 days, in adults with acute maxillary sinusitis (AMS). A total of 754 patients with AMS of less than 28 days’ duration were randomized to receive either telithromycin for 5 days followed by placebo for 5 days, telithromycin for 10 days, or amoxicillin/clavulanic acid for 10 days. Clinical outcome was assessed at a test-of-cure (TOC) visit between days 17 and 24 and at a late post-therapy visit between days 31 and 45. Analysis of clinical outcome on a per-protocol basis (n = 434) demonstrated therapeutic equivalence among the three regimens at the TOC visit; in each treatment group, the clinical cure rate was approximately 75%. Only a few patients (3 to 5 in each group) had relapsed by the late post-therapy follow-up visit. Telithromycin was generally safe and well tolerated. The most common adverse events were mild or moderate gastrointestinal effects, which occurred with similar frequency in all three groups. We conclude that 5 or 10 days of telithromycin at 800 mg once daily is as effective clinically and as well tolerated as 10 days of treatment with amoxicillin/clavulanic acid. Telithromycin, therefore, appears to be a valuable option for the treatment of AMS.

Cure Rates

In a randomized double-blind study fifty-four patients suffering from acute maxillary sinusitis were treated for 10 days with daily doses of sulphadiazine/trimethopim (1 g) and sulphamethoxazole/trimethoprim (1.92 g), respectively. The efficacy was evaluated clinically at two follow-up visits. X-ray investigations were performed at admission and after the therapy. Of thirty-nine patients finally evaluated, thirty-seven showed a favourable result. After 6–8 days of therapy there was significant difference in cure rates in favour of sulphadiazine/trimethoprim (p < 0.05) while the outcome as evaluated after treatment was similar for both drugs.

In this multicentre, multinational, comparative, double-blind clinical trial, out-patients with both symptoms and radiographic evidence of acute sinusitis were randomly assigned to receive either a seven-day, once daily (o.d.) oral regimen of moxifloxacin (400 mg) or a 10-day o.d. oral regimen of trovafloxacin (200 mg). Among 452 patients considered valid for clinical efficacy, moxifloxacin treatment was found to be statistically equivalent to trovafloxacin (96.9 per cent vs 92.1 per cent -95 per cent CI = 0.6 per cent; 8.9 per cent) at the seven to 10 days post-therapy assessment. At follow-up, the success rate in the moxifloxacin group was 94.9 per cent and that for the trovafloxacin group was 97.6 per cent (95 per cent CI = -4.9 per cent; 1.3 per cent). The predominant causative organisms were Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus followed by Enterobacteriaceae and Moraxella catarrhalis. The bacteriological success rate at the post-therapy evaluation was similar in both treatment groups: 94.4 per cent and 90.1 per cent in the moxifloxacin and trovafloxacin groups respectively (95 per cent CI = −3.0 per cent; 11.9 per cent). Only three of the 103 baseline isolated pathogens still persisted in the moxifloxacin group, whereas there were 10 of the 121 isolates that failed to respond in the trovafloxacin treatment group. At least one drug-related event was reported by 16.9 per cent of the moxifloxacin-treated patients and by 22.3 per cent of those who received trovafloxacin. CNS events such as dizziness and vertigo were reported more than five times more often in patients receiving trovafloxacin than in the moxifloxacin group. Trovafloxacin recipients were also more than twice as likely to discontinue treatment due to adverse events than moxifloxacin-treated patients. Overall, moxifloxacin was at least as effective clinically and bacteriologically as trovafloxacin and better tolerated.

Abstract Aim: To study whether changes in drug preferences in the Dutch guideline for the treatment of Urinary Tract Infection (UTI) for General Practitioners (GPs) in 2013, resulted in corresponding changes in antibiotic dispensing. Background: For the treatment of uncomplicated UTI, nitrofurantoin remained the first choice, while fosfomycin became the second choice and changed ranks with trimethoprim. For a subsequent febrile UTI, ciprofloxacin became the first choice and changed ranks with amoxicillin/clavulanic acid, co-trimoxazole remained the third choice. Methods: In this observational cross-sectional study, routinely collected dispensing data from the Dutch Foundation of Pharmaceutical Statistics from 2012 to 2017 were used. The number of women 18 years and older, treated with one of the guideline antibiotics for uncomplicated UTI and subsequent febrile UTI were analysed annually. Proportions were calculated. Data were stratified for age categories. Failure of uncomplicated UTI treatment was defined as the dispensing of an antibiotic for febrile UTI within 14 days after the dispensing of an antibiotic for uncomplicated UTI. Findings: Data were available from 81% of all pharmacies in 2012 to 89% in 2017. Percentages of women dispensed nitrofurantoin were relatively stable with 87.4% in 2012 and 84.4% in 2017. Percentages of women dispensed fosfomycin increased from 5.4% in 2012 to 21.8% in 2017, whereas percentages of women dispensed trimethoprim decreased from 17.8% to 8.0%. Within age categories, the percentage of women dispensed fosfomycin increased from 12.4% in women 18–30 years old to 36.7% in women above 80 years old. Percentages of women dispensed antibiotics for febrile UTI remained stable at 5% annually. Percentages of women receiving ciprofloxacin increased from 1.9% in 2012 to 3.3% in 2017, while those receiving amoxicillin/clavulanic acid decreased from 2.9% to 1.8%. New guideline recommendations resulted in corresponding changes in dispensed antibiotics for uncomplicated UTI and subsequent febrile UTI. Drug choices differed for age categories.

OBJECTIVE: To review the clinical microbiology and therapeutic use of dirithromycin, emphasizing comparative data between dirithromycin and the standard macrolide erythromycin, as well as clarithromycin and azithromycin. DATA SOURCES: A MEDLINE search of English-language literature during the years 1966–1996, and an extensive review of journals were conducted to prepare this article. DATA EXTRACTION: The data on pharmacokinetics, adverse effects, and drug interactions were obtained from open and controlled studies. Controlled single- or double-blind studies were evaluated to assess the efficacy of dirithromycin in the treatment of various upper and lower respiratory tract infections, as well as skin and soft tissue infections. DATA SYNTHESIS: The spectrum of activity of dirithromycin is similar to that of erythromycin, clarithromycin, or azithromycin, with some notable exceptions. Dirithromycin was more active in vitro against Campylobacter jejuni and Borrelia burgdorferi than was erythromycin or clarithromycin, but in general demonstrated less activity than erythromycin, clarithromycin, or azithromycin against a majority of microorganisms. The pharmacokinetic profile of dirithromycin offers the advantages of once-daily dosing and high and prolonged tissue concentrations; dosing adjustments are not needed in the elderly or in patients with renal or mild hepatic impairment. Clinical efficacy and bacteriologic eradication rates with dirithromycin and erythromycin are comparable for the treatment of respiratory and skin and soft tissue infections due to susceptible pathogens. Dirithromycin appears to have adverse effect profiles similar to those of the other macrolides, with reported problems most often related to the gastrointestinal tract. Dirithromycin does not seem to cause clinically important interactions with drugs such as theophylline, oral contraceptives, cyclosporine, or terfenadine. CONCLUSIONS: Dirithromycin offers some attractive pharmacokinetic properties. The long elimination half-life of dirithromycin allows once-daily dosing and higher and more prolonged tissue concentrations than are achievable with erythromycin. The spectrum of activity, adverse effect profile, clinical efficacy, and bacteriologic eradication rate of dirithromycin may be similar to those of erythromycin. No significant drug interactions with dirithromycin have been reported. Based on available data, dirithromycin may not offer any unique clinical advantage over clarithromycin or azithromycin. Future clinical trials may reveal a special role for dirithromycin in patient care.

Background. Klebsiella pneumoniae and Escherichia coli are the major extended-spectrum β-lactamase- (ESBL-) producing organisms increasingly isolated as causes of complicated urinary tract infections and remain an important cause of failure of therapy with cephalosporins and have serious infection control consequence. Objective. To assess the prevalence and antibiotics resistance patterns of ESBL-producing Escherichia coli and Klebsiella pneumoniae from community-onset urinary tract infections in Jimma University Specialized hospital, Southwest Ethiopia, 2016. Methodology. A hospital-based cross-sectional study was conducted, and a total of 342 urine samples were cultured on MacConkey agar for the detection of etiologic agents. Double-disk synergy (DDS) methods were used for detection of ESBL-producing strains. A disc of amoxicillin + clavulanic acid (20/10 µg) was placed in the center of the Mueller–Hinton agar plate, and cefotaxime (30 µg) and ceftazidime (30 µg) were placed at a distance of 20 mm (center to center) from the amoxicillin + clavulanic acid disc. Enhanced inhibition zone of any of the cephalosporin discs on the side facing amoxicillin + clavulanic acid was considered as ESBL producer. Results. In the current study, ESBL-producing phenotypes were detected in 23% (n = 17) of urinary isolates, of which Escherichia coli accounts for 76.5% (n = 13) and K. pneumoniae for 23.5% (n = 4). ESBL-producing phenotypes showed high resistance to cefotaxime (100%), ceftriaxone (100%), and ceftazidime (70.6%), while both ESBL-producing and non-ESBL-producing isolates showed low resistance to amikacin (9.5%), and no resistance was seen with imipenem. In the risk factors analysis, previous antibiotic use more than two cycles in the previous year (odds ratio (OR), 6.238; 95% confidence interval (CI), 1.257–30.957; p = 0.025) and recurrent UTI more than two cycles in the last 6 months or more than three cycles in the last year (OR, 7.356; 95% CI, 1.429–37.867; p = 0.017) were found to be significantly associated with the ESBL-producing groups. Conclusion. Extended-spectrum β-lactamases- (ESBL-)producing strain was detected in urinary tract isolates. The occurrence of multidrug resistance to the third-generation cephalosporins, aminoglycosides, fluoroquinolones, trimethoprim-sulfamethoxazole, and tetracyclines is more common among ESBL producers. Thus, detecting and reporting of ESBL-producing organisms have paramount importance in the clinical decision-making.

Abstract Background Rezafungin (RZF) is a novel echinocandin exhibiting distinctive pharmacokinetics/pharmacodynamics. STRIVE was a phase 2, double-blind, randomized trial designed to compare the safety and efficacy of RZF once weekly (QWk) to caspofungin (CAS) once daily for treatment of candidemia and/or invasive candidiasis (IC). Methods Adults with systemic signs and mycological confirmation of candidemia and/or IC were randomized to RZF 400 mg QWk (400 mg), RZF 400 mg on week 1 then 200 mg QWk (400/200 mg), or CAS 70 mg as a loading dose followed by 50 mg daily for ≤ 4 weeks. Efficacy assessments included overall cure (resolution of signs of candidemia/IC + mycological eradication) at day 14 (primary endpoint), investigator-assessed clinical response at day 14, and 30-day all-cause mortality (ACM) (secondary endpoints), and time to negative blood culture. Safety was evaluated by adverse events and ACM through follow-up. Results Of 207 patients enrolled, 183 were in the microbiological intent-to-treat population (~21% IC). Overall cure rates were 60.5% (46/76) for RZF 400 mg, 76.1% (35/46) for RZF 400/200 mg, and 67.2% (41/61) for CAS; investigator-assessed clinical cure rates were 69.7% (53/76), 80.4% (37/46), and 70.5% (43/61), respectively. 30-day ACM was 15.8% for RZF 400 mg, 4.4% for RZF 400/200 mg, and 13.1% for CAS. Candidemia was cleared in 19.5 and 22.8 hours in RZF and CAS patients, respectively. No concerning safety trends were observed; ACM through follow-up was 15.2% (21/138) for RZF and 18.8% (13/69) for CAS. Conclusions RZF was safe and efficacious in the treatment of candidemia and/or IC.

Abstract Objectives To determine antibiotic susceptibility of Streptococcus pneumoniae and Haemophilus influenzae isolates from community-acquired respiratory tract infections (CA-RTIs) collected in 2015–17 from Turkey. Methods MICs were determined by CLSI broth microdilution and susceptibility was assessed using CLSI, EUCAST (dose-specific) and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. Results A total of 179 S. pneumoniae and 239 H. influenzae isolates were collected. Few (27.9%) pneumococci were penicillin susceptible by CLSI oral or EUCAST low-dose breakpoints, but by EUCAST high-dose or CLSI IV breakpoints 84.4% were susceptible. The most active antibiotics (excluding penicillin IV) by CLSI breakpoints were fluoroquinolones (98.9% of isolates susceptible), ceftriaxone (83.2%), amoxicillin (78.8%) and amoxicillin/clavulanic acid (78.8%). Pneumococcal susceptibility to amoxicillin and amoxicillin/clavulanic acid was lower using EUCAST low-dose breakpoints (49.7%), although susceptibility increased when using EUCAST high-dose (57.0%–58.1%) and PK/PD (78.8%–87.7%) breakpoints. Twenty-three H. influenzae isolates were β-lactamase positive, with 11 characterized as β-lactamase negative and ampicillin resistant following EUCAST criteria and 5 by CLSI criteria. Generally antibiotic susceptibility was high using CLSI breakpoints: ≥92.9% for all antibiotics except ampicillin (87% by CLSI and EUCAST breakpoints) and trimethoprim/sulfamethoxazole (67.4% and 72% by CLSI and EUCAST breakpoints, respectively). Susceptibility using EUCAST breakpoints (where these are published) was similar, except for cefuroxime (oral) with 3.8% of isolates susceptible. PK/PD breakpoints indicated low susceptibility to macrolides (5.9%–10%) and cefaclor (13%). The application of different EUCAST breakpoints for low and higher doses for some of the antibiotics (amoxicillin, amoxicillin/clavulanic acid, ampicillin, penicillin, ceftriaxone, clarithromycin, erythromycin, levofloxacin and trimethoprim/sulfamethoxazole) allowed, for the first time in a SOAR study, the effect of raising the dosage on susceptibility to be quantified. Conclusions Antibiotic susceptibility of S. pneumoniae was generally low, which is in keeping with evidence of inappropriate and high antibiotic use in Turkey. H. influenzae susceptibility was high. These data are important for empirical therapy of CA-RTIs.

102 Background: BOLERO-2, a multinational, double-blind, placebo-controlled, phase III study in postmenopausal women with estrogen-receptor–positive breast cancer (BC) refractory to nonsteroidal aromatase inhibitors (NSAIs), showed significant clinical benefits with the addition of EVE to exemestane (EXE) (Baselga J et al. NEJM2011 Epub). As bone resorption is an important factor in BC mets, it is interesting to study bone-related effects of EVE. In preclinical studies, mTOR inhibition was associated with decreased osteoclast survival and activity. Exploratory analyses in BOLERO-2 evaluated the effects of EVE vs placebo (PBO) on BM levels and BC progression in bone in pts with bone mets at baseline. Methods: Eligible pts were treated with EXE (25 mg once daily) and randomized (2:1) to EVE (10 mg once daily) or PBO. Bone turnover markers (BMs) were exploratory endpoints analyzed at 6 and 12 wks after treatment initiation and included bone-specific alkaline phosphatase, amino-terminal propeptide of type I collagen, and C-terminal cross-linking telopeptide of type I collagen. Progressive disease in bone (PDB) was defined as worsening of a preexisting bone lesion or a new bone lesion. Results: Baseline disease characteristics, including bone mets at baseline (n = 370, 76% EVE vs n = 184, 77% PBO), were well balanced between arms (N = 724), and baseline bisphosphonate use was not (44% EVE vs 55% PBO). At 12.5 mo median follow-up, progression-free survival (primary endpoint), overall response rate, and clinical benefit rate (p < 0.0001, all) were significantly higher with EVE (n = 485) vs PBO (n = 239). BM levels at 6 and 12 wks increased vs baseline with PBO but decreased with EVE. The cumulative incidence rate of BC PBD was lower for EVE vs PBO at day 60 (3.03% vs 6.16%, respectively), and this trend was sustained beyond 6 months. Updated results will be presented. All bone-related adverse events reported were grade 1-2 and occurred with similar frequency in EVE (2.9%)- and PBO (3.8%)-treated patients. Conclusions: Exploratory analyses from BOLERO-2 suggest that adding EVE has beneficial effects on bone turnover and BC progression in bone in pts receiving EXE therapy for NSAI-refractory BC.
