Current Concepts in Adult Acute Rhinosinusitis.
    American family physician, 2016, Jul-15, Volume: 94, Issue:2

    Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory care. Most cases of acute rhinosinusitis are caused by viral upper respiratory infections. A meta-analysis based on individual patient data found that common clinical signs and symptoms were not effective for identifying patients with rhinosinusitis who would benefit from antibiotics. C-reactive protein and erythrocyte sedimentation rate are somewhat useful tests for confirming acute bacterial maxillary sinusitis. Four signs and symptoms that significantly increase the likelihood of a bacterial cause when present are double sickening, purulent rhinorrhea, erythrocyte sedimentation rate greater than 10 mm per hour, and purulent secretion in the nasal cavity. Although cutoffs vary depending on the guideline, antibiotic therapy should be considered when rhinosinusitis symptoms fail to improve within seven to 10 days or if they worsen at any time. First-line antibiotics include amoxicillin with or without clavulanate. Current guidelines support watchful waiting within the first seven to 10 days after upper respiratory symptoms first appear. Evidence on the use of analgesics, intranasal corticosteroids, and saline nasal irrigation for the treatment of acute rhinosinusitis is poor. Nonetheless, these therapies may be used to treat symptoms within the first 10 days of upper respiratory infection. Radiography is not recommended in the evaluation of uncomplicated acute rhinosinusitis. For patients who do not respond to treatment, computed tomography of the sinuses without contrast media is helpful to evaluate for possible complications or anatomic abnormalities. Referral to an otolaryngologist is indicated when symptoms persist after maximal medical therapy and if any rare complications are suspected.

Clinical and bacteriological efficacy of 5-day telithromycin in acute maxillary sinusitis: a pooled analysis.
    The Journal of infection, 2005, Volume: 50, Issue:3

    To compare the efficacy and tolerability of a 5-day course of telithromycin (800 mg once daily) with a 10-day course of telithromycin or standard comparators (amoxicillin-clavulanate 500/125 mg three times daily or cefuroxime axetil 250 mg twice daily) in patients with acute maxillary sinusitis (AMS).. Data from three randomised double blind studies were pooled. The studies included patients with clinical symptoms of AMS and sinus X-ray findings of total opacity, air-fluid levels or mucosal thickening.. Pooled analysis of results for 5-day telithromycin revealed overall clinical cure rates of 83.6% (383/458 patients) at post-therapy (days 17-24) and 78.9% (330/418 patients) at late post-therapy (days 31-45) in the per-protocol population. Clinical cure rates at post-therapy were equivalent to those observed with 10-day telithromycin (82.5% vs 81.7%) or comparator treatment (80.9% vs 77.4%). Moreover, clinical cure rates exceeded 80% in subgroups of patients of interest, including those with severe infection and those fulfilling more stringent criteria for bacterial AMS. A satisfactory bacteriological outcome was achieved in 87.6% of patients. The 5-day telithromycin regimen was well tolerated.. Telithromycin once daily for 5 days offers effective treatment for AMS and is comparable to 10-day courses of standard treatments.

Telithromycin for the treatment of acute bacterial maxillary sinusitis: a review of a new antibacterial agent.
    Southern medical journal, 2005, Volume: 98, Issue:9

    Telithromycin, the first approved ketolide antibiotic, was developed to treat community-acquired respiratory tract infections, including acute bacterial maxillary sinusitis (ABMS). A previously published study showed that a 5-day course of 800 mg telithromycin once daily is as effective as a 10-day course in the treatment of ABMS.. Data were pooled from two controlled, multinational, prospective, randomized, double-blinded ABMS trials comparing 5-day telithromycin (800 mg once daily) with 10-day amoxicillin-clavulanate (500/125 mg 3 times daily) and cefuroxime axetil (250 mg twice daily). Clinical cure and bacteriologic eradication rates were compared by means of descriptive statistics.. The clinical cure rate for telithromycin was 80.9% versus 77.4% for comparators; bacteriologic eradication rate for telithromycin was 84.9% versus 81.7% for comparators. Most adverse events were mild to moderate in intensity and, most commonly, gastrointestinal in nature.. These results support the conclusion that 5 days of treatment with telithromycin is as safe and effective in patients with ABMS as a 10-day course of treatment with amoxicillin-clavulanate or cefuroxime axetil.

Acute bacterial maxillary sinusitis: results of U.S. and European comparative therapy trials.
    The American journal of medicine, 1992, Jun-22, Volume: 92, Issue:6A

    Loracarbef, which is the first agent of the carbacephem class of beta-lactam antibiotics to be developed, provides good activity against a broad spectrum of bacteria. A single-blinded, randomized, parallel clinical trial in 10 centers in the United States compared the efficacy and safety of loracarbef with that of amoxicillin/clavulanate potassium in the treatment of acute bacterial maxillary sinusitis. A 7-10-day regimen of loracarbef (400 mg twice daily) was as effective as amoxicillin/clavulanate (500/125 mg three times a day) and resulted in somewhat fewer side effects. The results of a European trial in Sweden, Finland, and Iceland showed that loracarbef was clinically more effective than doxycycline in the treatment of acute bacterial maxillary sinusitis.

[Treatment of acute maxillary sinusitis in adults. Comparison of cefpodoxime-proxetil and amoxicillin-clavulanic acid].
    Presse medicale (Paris, France : 1983), 2006, Volume: 35, Issue:1 Pt 1

    The aim was to demonstrate the equivalence of the clinical efficacy and safety of cefpodoxime-proxetil (200 mg bid for 5 days) to that of amoxicillin-clavulanic acid (1 g/125 mg bid for 8 days) in adults with acute maxillary sinusitis.. In this prospective, multicenter, centrally-randomized, open-label study, 73 general practitioners and 11 ear, nose, and throat specialists included 512 patients with unilateral acute maxillary sinusitis.. The clinical success rates at day 12-19 in the per-protocol population (primary analysis) were 92.3% (215/233) in the cefpodoxime-proxetil group and 93.6% (204/218) in the amoxicillin-clavulanic acid group. The 95% confidence interval of [6.5%; 3.9%] demonstrated that cefpodoxime-proxetil was not inferior to amoxicillin-clavulanic acid. Cure rates at follow-up (day 25-30) were 90.6% and 92.7%, respectively. Results were similar in the intent-to-treat population. Compliance was significantly better in the cefpodoxime-proxetil group (99.2% versus 95.5%; p=0.011). Tolerance was also significantly better: 1.2% (3/247) of cefpodoxime-proxetil patients reported a treatment-related adverse event, compared with 10.7% (26/244) in the amoxicillin-clavulanic acid group (p<0.001). Most events were gastrointestinal and of mild to moderate intensity.. In this study, a 5-day course of cefpodoxime-proxetil at 200 mg bid was as clinically effective as amoxicillin-clavulanic acid 1 g/125 mg bid for 8 days with a significantly better safety profile and compliance.

Bacteriological efficacy of 5-day therapy with telithromycin in acute maxillary sinusitis.
    International journal of antimicrobial agents, 2005, Volume: 25, Issue:3

    Increasing resistance among the key pathogens responsible for community-acquired respiratory tract infections, namely Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis, has the potential to limit the effectiveness of the antibacterial agents available to treat these infections. Moreover, there are regional differences in the susceptibility patterns observed and, as treatment is usually empirical, choosing an effective treatment can be challenging. Telithromycin, the first ketolide to be approved for clinical use, offers an activity profile that covers the key respiratory pathogens including penicillin- and macrolide-resistant S. pneumoniae as well as beta-lactamase-producing H. influenzae and M. catarrhalis. In a pooled analysis of three large controlled clinical trials involving patients with acute maxillary sinusitis, the bacteriological efficacy of 5- or 10-day treatment with telithromycin and 10-day treatment with comparators was evaluated. Telithromycin administered as a once-daily 800 mg dose for 5 days achieved eradication rates of 91.8, 87.5 and 92.9% for S. pneumoniae, H. influenzae and M. catarrhalis, respectively. Bacteriological eradication of 8/10 and 12/14 isolates of S. pneumoniae resistant to penicillin and erythromycin, respectively, was also reported following 5-day treatment with telithromycin. The clinical efficacy of this regimen was equivalent to that of a 10-day regimen of telithromycin or standard 10-day courses of amoxicillin-clavulanic acid or cefuroxime axetil. Telithromycin 800mg given for 5 days was well tolerated, with the majority of adverse events being of mild or moderate intensity. These data suggest that telithromycin provides effective first-line therapy for use in patients with acute maxillary sinusitis in a short and convenient once-daily dosage regimen.

An open label, randomized comparative study of levofloxacin and amoxicillin/clavulanic acid in the treatment of purulent sinusitis in adult Thai patients.
    Rhinology, 2004, Volume: 42, Issue:1

    The objective of the study was to compare the clinical efficacy and bacteriological response of levofloxacin and amoxicillin/clavulanic acid (co-amoxiclav) in the treatment of purulent maxillary sinusitis. Sixty patients randomly received either levofloxacin 300 mg orally once daily (LEV group) or co-amoxiclav 625 mg three times a day (COA group) for 14 days. Thirty four patients were in the LEV group and 26 patients were in the COA group. The mean total symptom score was significantly decreased after treatment and was comparable between both groups. Radiological improvement was 61.8% in the LEV group (41.2% resolution, 20.6% improvement) and 61.5% in the COA group (26.9% resolution, 34.6% improvement). Pretreatment maxillary antral aspiration cultures were positive in 28 patients (82.4%) in the LEV group and 20 patients (76.9%) in the COA group. Bacteriological eradication was 78.5% in the LEV group and 70.0% in the COA group, which was not significantly different. In the LEV group, the eradication rate for major pathogens of acute sinusitis was 100% for H. influenzae (both betalactamase +ve and -ve), 100% for S. pneumoniae and S. aureus, 100% for Neisseria species, and 66.7% for P. aeruginosa. The eradication rate in the COA group was 75% for H. influenzae (both betalactamase +ve and -ve), 100% for S. pnumoniae and S. aureus, 50% for Neisseria species, and 0% for P. aeruginosa. There were no significant changes in vital sign measurements or hemato-biochemical parameters at the end of treatment as compared to baseline values, in both groups. Adverse events were found in 8.8% of patient in the LEV group and in 7.7% of patients in the COA group. Adverse events included nausea, abdominal pain, and diarrhea. All the adverse events in both groups were mild and resolved spontaneously. This study demonstrated that levofloxacin 300 mg orally once daily was as effective and safe as amoxicillin/clavulanic acid 625 mg three times a day in the treatment of maxillary sinusitis, either acute or acute exacerbation. Both drugs showed bacteriological efficacy that was not significantly different. The once daily dosage regimen is more applicable, convenience and has better compliance.

Efficacy and tolerability of telithromycin for 5 or 10 days vs amoxicillin/clavulanic acid for 10 days in acute maxillary sinusitis.
    Ear, nose, & throat journal, 2003, Volume: 82, Issue:8

    Telithromycin (HMR 3647) is a new ketolide antimicrobial that was developed for the treatment of community-acquired respiratory tract injections. 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.

[Sinusal penetration of amoxicillin-clavulanic acid. Formulation 1 g./125 mg., twice daily versus formulation 500 mg./125 mg., three times daily].
    Presse medicale (Paris, France : 1983), 2002, Oct-19, Volume: 31, Issue:34

    In order to meet the evolution of pneumococcus resistance to beta-lactam antibiotics, a new formulation of amoxicillin (AMX) and clavulanic acid (CA), with twice as much AMX (1 g/125 mg vs. 500 mg/125 mg) was developed for the treatment of acute pneumonia in patients at risk. This formulation can also be used in the treatment of acute maxillary sinusitis using a 1 g/125 mg regimen twice-daily.. Compare the sinusal penetration of AMX and CA (1 g/125 mg twice-daily vs. 500 mg/125 mg three times a day) when administered at both regimens to demonstrate equivalent pharmacokinetic and pharmacodynamic behaviour of the former when compared to the latter.. Concentrations of AMX and CA were measured in the anterior ethmoid, maxillary, posterior ethmoid sinus and in the middle nasa concha in 62 patients undergoing surgery for nasosinusal polyps. Patients randomised in two groups corresponding to 2 oral regimens, received either 1 g/125 mg twice a day or 500 mg/125 mg three times a day for 4 days. The last dose in both groups was administered 1 h 30, 3, 5 or 8 hrs prior to surgery. Serum samples were taken simultaneously to tissue samples. AMX and CA were measured by high performance liquid chromatography. Exogenous and above all endogenous blood contamination were taken into account with the hematocrit as well as blood and tissue haemoglobin concentrations. Comparisons of tissue concentrations were made for each sampling time, according to values obtained for a specific tissue with both doses on one hand, and on the other to values obtained with a specific dose in different tissues. The calculated pharmacodynamic parameters, which are considered to be predictive for bacteriological and clinical efficacy, result directly from tissue concentrations of AMX. tissue inhibitory quotients (IQtissue = Tissue concentration/MIC). time above MICs for serum and tissue concentrations (T > MIC).. As regards AMX, whatever the dose, at 1 h 30 and at 3 hrs, tissue concentrations did not differ significantly whatever the tissue studied (from 1.1 to 2.5 micrograms/g). Conversely, at 5 and 8 hrs, they were greater than after the 1 g/125 mg regimen given twice-daily (0.06-0.7 vs. 0.7-1.8 micrograms/g). If we consider a given dose, the comparison between the various tissues showed identical concentrations in the four tissues studied at each sampling time, except in two cases with the dose of 500 mg/125 mg 3 times a day. T > MIC for serum and tissue showed higher values than those required for AMX/pneumococcus association (40-50%) with, nevertheless, greater tissue values for the 1 g/125 mg dose given twice-daily when MIC was of 1 microgram/ml (40-52% vs. 50-66%). The maximum tissue inhibitory quotients were also greater with the twice-daily 1 g/125 mg dose, when calculated with MIC 50 or 90 of S. Pneumoniae, H. influenzae, M. catarrhalis or S. pyogenes. As for CA, concentrations were equivalent for both doses at each sampling time and greater than those required in vitro during respectively 4 and 5 hours for beta-lactamases H. influenzae and M. catarrhalis.. A least an equivalence between both dose regimens was observed, with occasionally a superiority of the twice-daily 1 g/125 mg dose, in terms of pharmacokinetics, tissue penetration and pharmacodynamics for both AMX and CA. This new regimen therefore appears more appropriate for the treatment of acute maxillary sinusitis in adults.

A multicenter, randomized, investigator-blinded study of 5- and 10-day gatifloxacin versus 10-day amoxicillin/clavulanate in patients with acute bacterial sinusitis.
    Clinical therapeutics, 2002, Volume: 24, Issue:2

    Treatment guidelines for acute bacterial sinusitis recommend 10 to 14 days of therapy with amoxicillin/clavulanate, high-dose amoxicillin, cefpodoxime, cefuroxime, or a newer fluoroquinolone.. This study compared the clinical efficacy of short-course (5-day) gatifloxacin with standard 10-day regimens of amoxicillin/clavulanate or gatifloxacin in patients with a diagnosis of acute, uncomplicated maxillary sinusitis.. This was a multicenter, investigator-blinded study in adult patients (age >18 years) with physical findings, signs and symptoms (for at least 7 days), and radiographic findings indicating acute, uncomplicated maxillary sinusitis. Patients were randomized to receive gatifloxacin 400 mg once daily for 5 days, gatifloxacin 400 mg once daily for 10 days, or amoxicillin/clavulanate 875 mg twice daily for 10 days. Clinical response was assessed once between days 3 and 5 of treatment, once I to 3 days after the completion of study treatment, once 7 to 14 days posttreatment (test-of-cure visit), and once 21 to 28 days posttreatment. Safety was assessed throughout the study.. The study enrolled 445 patients. The treatment groups were similar in terms of history of sinusitis, presenting signs and symptoms, and radiographic findings. The most common presenting symptoms were nasal congestion, sinus tenderness, and purulent nasal discharge (>90% of patients); 99% of patients had abnormal radiographic findings. At the test-of-cure visit, clinical cure rates for clinically evaluable patients in the 3 treatment groups were 74% (102/137) for 5-day gatifloxacin, 80% (101/127) for 10-day gatifloxacin, and 72% (101/ 141) for 10-day amoxicillin/clavulanate (95% CI for the difference in cure rates: 5-day gatifloxacin vs amoxicillin/clavulanate, -7.6 to 13.2; 5- vs 10-day gatifloxacin, -15.2 to 5.1; 10-day gatifloxacin vs amoxicillin/clavulanate, -2.3 to 18.1). The distribution and incidence of drug-related adverse events (AEs) were comparable between treatment groups, and the majority (>95%) were mild or moderate in severity. The most common drug-related AEs included vaginitis, diarrhea, and nausea.. In this population of patients with acute, uncomplicated sinusitis of presumed bacterial origin, a short course (5 days) of gatifloxacin therapy was associated with comparable clinical cure rates and tolerability to those of standard 10-day therapy with gatifloxacin or amoxicillin/clavulanate.

Moxifloxacin versus amoxicillin clavulanate in the treatment of acute maxillary sinusitis: a primary care experience.
    International journal of clinical practice, 2001, Volume: 55, Issue:5

    In this prospective, multicentre, randomised, non-blinded phase III clinical trial, 475 adult patients with acute sinusitis received a 10-day oral regimen of either moxifloxacin (400 mg once daily) or amoxicillin clavulanate (875 mg twice daily). The primary measure of efficacy was clinical resolution. Secondary outcome measures included clinical relapse at follow-up and evaluation of patient reported outcomes. Of 471 adults comprising the intent-to-treat population (234 moxifloxacin, 237 amoxicillin/clavulanate), moxifloxacin treatment was statistically equivalent to amoxicillin/clavulanate at the test-of-cure visit (85% vs 82%; 95% CI -6%, 13%). Analysis of the efficacy evaluable population, confirmed statistical equivalence (86% vs 84%; 95% CI -7%, 13%). Of note, by day 3 of treatment, significantly more moxifloxacin-treated patients (n = 47; 24%), than amoxicillin/clavulanate-treated patients (n = 28; 14%), reported feeling better (p < 0.02). Frequency of drug-related adverse events were similar between groups: nausea (11% moxifloxacin, 5% amoxicillin/clavulanate) and diarrhoea (3% moxifloxacin, 10% amoxicillin clavulanate). In conclusion, once-daily moxifloxacin is as effective and safe as twice-daily amoxicillin/clavulanate in the treatment of acute sinusitis. Moxifloxacin is associated with more rapid symptomatic relief.

Efficacy and safety of cefdinir in the treatment of maxillary sinusitis.
    European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery, 2000, Volume: 257, Issue:3

    Cefdinir is a new, extended-spectrum, orally active, third-generation cephalosporin that is resistant to bacterial beta-lactamase production. To evaluate efficacy and safety of the antibiotic in maxillary sinusitis, its use was compared with amoxicillin/clavulanate (amox/clav), which is a well-accepted beta-lactamase-resistant antibiotic. In this investigator-blinded multicenter phase III clinical study, 569 patients were randomly assigned to one of three treatment regimens: one daily dose of cefdinir 600 mg (OD), cefdinir 300 mg every 12 h (BD), and amox/clav 500/125 mg every 8 h. All antibiotics were administered orally for 10 days. Maxillary sinusitis was documented by typical clinical signs and symptoms and was confirmed by X-ray imaging. Before treatment, the genus and species of any pathogens were determined from sinus aspirates. Cultures were tested for beta-lactmase production and in vitro resistance to cefdinir and amox/clav. The effectiveness of antibiotic treatment was evaluated 7-14 days after therapy and whether or not recurrent clinical symptoms or persistent infection was determined 21-35 days post-therapy. The appearance of any adverse events was classified as associated or not associated with the medication of the study. Present findings showed that the in vitro susceptibility of pathogens to cefdinir and amox/clav was similar. Cefdinir OD or BD was therapeutically as effective as or better than amox/clav, although cefdinir BD was not as useful as amox/clav clinically. Cefdinir OD and BD and amox/clav were well tolerated. The statistical incidence of adverse events was the same among the three treatment groups, although cefdinir OD treatment had significantly fewer treatment discontinuations due to adverse events than BD and amox/clav.

Comparison of cefuroxime axetil and amoxicillin/clavulanate in the treatment of acute bacterial sinusitis.
    Clinical therapeutics, 1999, Volume: 21, Issue:7

    This double-masked, multicenter, randomized clinical trial compared the efficacy and tolerability of cefuroxime axetil and amoxicillin/clavulanate in the treatment of acute bacterial maxillary sinusitis. A total of 263 patients with acute bacterial maxillary sinusitis were randomly assigned to receive 10 days of treatment with either cefuroxime axetil 250 mg twice daily (n = 132) or amoxicillin/clavulanate 500/125 mg 3 times daily (n = 131). Patients' responses to treatment were assessed once during treatment (6 to 8 days after the start of treatment), at the end of treatment (1 to 3 days posttreatment), and at follow-up (26 to 30 days after cessation of treatment). Clinical success, defined as cure or improvement, was equivalent in the cefuroxime axetil and amoxicillin/ clavulanate groups at the end-of-treatment and follow-up assessments. Patients in both groups showed improvements in symptoms of acute sinusitis at the during-treatment visit. Treatment with amoxicillin/clavulanate was associated with a significantly higher incidence of drug-related adverse events than treatment with cefuroxime axetil (29% vs 17%), primarily reflecting a higher incidence of gastrointestinal adverse events (23% vs 11%), particularly diarrhea. Two patients in the cefuroxime axetil group and 8 patients in the amoxicillin/clavulanate group withdrew from the study due to adverse events (P = 0.06). These results indicate that cefuroxime axetil 250 mg twice daily is as effective as amoxicillin/clavulanate 500 mg 3 times daily in the treatment of acute sinusitis and produces fewer gastrointestinal adverse events. cefuroxime axetil, amoxicillin/clavulanate, acute sinusitis.

    A total of 251 adults with chronic sinusitis were enrolled into this prospective multicentre, double-blind, double-placebo comparison of ciprofloxacin (500 mg twice daily) with amoxycillin/clavulanic acid (500 mg three times daily). The diagnosis of chronic sinusitis (persistence of clinical symptoms for at least 3 months) was confirmed by computerized tomography scan and/or sinusoscopy prior to therapy. Patients at inclusion had purulent or muco-purulent rhinorrhoea. Staphylococcus aureus (n = 45), Haemophilus influenzae (n = 35), Streptococcus pneumoniae (n = 32) and enterobacteriaceae (n = 31) were isolated from pre-treatment aspirates of the middle meatus. Treatment lasted 9 days, at the end of which nasal discharge disappeared in 71/118 (60.2%) patients of the ciprofloxacin group and 69/123 (56.1%) of those in the amoxycillin/clavulanic acid group. The clinical cure and bacteriological eradication rates were 58.6% versus 51.2% and 88.9% versus 90.5% for ciprofloxacin and amoxycillin/clavulanic acid, respectively. These differences were not significant, however, amongst patients who had a positive initial culture and who were evaluated 40 days after treatment. Ciprofloxacin recipients had a significantly higher cure rate than those treated with amoxycillin/clavulanic acid (83.3% vs. 67.6%, p = 0.043). Clinical tolerance was significantly better with ciprofloxacin (p = 0.012), essentially due to a large number of gastro-intestinal related side-effects in the amoxycillin/clavulanic acid group (n = 35). Ciprofloxacin proved to be at least as effective as amoxycillin/clavulanic acid. The superior safety profile, a twice daily dosage regimen, suggests that ciprofloxacin may be a useful therapeutic alternative for the treatment of chronic sinusitis.

Efficacy of clarithromycin vs. amoxicillin/clavulanate in the treatment of acute maxillary sinusitis.
    Ear, nose, & throat journal, 1993, Volume: 72, Issue:12

    A new macrolide drug, clarithromycin (Biaxin) was compared with amoxicillin/clavulanate (Augmentin) in a single-blind (investigator-blind), randomized, multicenter study of 497 outpatients with acute maxillary sinusitis; treatment was 500 mg clarithromycin bid (n = 246) or 500 mg amoxicillin/clavulanate tid (n = 251). Pathogens included Streptococcus pneumoniae in 22% of patients, Staphylococcus aureus in 16%, Haemophilus influenzae in 10%, and Moraxella catarrhalis in 7%. For evaluable patients, clinical success (cure or improvement) was noted for 97% (128/132) of clarithromycin recipients and 93% (119/128) amoxicillin/clavulanate recipients. Clinically significant improvement in signs and symptoms was comparable between groups. Bacteriologic cure rates were 87% (115/132) and 90% (115/128), respectively. Respective pathogen eradication rates were 87% (125/143) and 90% (125/139). Adverse events not due to concurrent conditions occurred in 41% of the former and 46% of the latter group; most were mild to moderate gastrointestinal upsets (21% and 38%, respectively; P < 0.001). We conclude that clarithromycin appears to be as effective as amoxicillin/clavulanate in acute maxillary sinusitis and may cause fewer gastrointestinal upsets.

Loracarbef (LY 163892) vs amoxicillin/clavulanate in bacterial maxillary sinusitis.
    Ear, nose, & throat journal, 1992, Volume: 71, Issue:5

    Loracarbef (LY 163892), a beta-lactam antibiotic (carbacephem), was compared with amoxicillin/clavulanate potassium in a 10-day, single-blind, randomized parallel trial in the treatment of acute bacterial maxillary sinusitis. Based on posttherapy aspirate and culture, there was a 95.2% bacteriologic cure rate in patients receiving loracarbef (400 mg twice daily) and an 86.7% cure rate in patients receiving amoxicillin/clavulanate (500/125 mg three times daily) (p = 0.359). Loracarbef was comparable in efficacy to amoxicillin/clavulanate with a more desirable safety profile.

Clinical comparison of cefuroxime axetil and amoxicillin/clavulanate in the treatment of patients with acute bacterial maxillary sinusitis.
    The American journal of medicine, 1992, Volume: 93, Issue:3

    This multicenter study compared the clinical and bacteriologic efficacy of two oral antibiotics, cefuroxime axetil and amoxicillin/clavulanate, in the treatment of acute bacterial maxillary sinusitis.. Three hundred seventeen patients with clinical and radiographic evidence of acute maxillary sinusitis were enrolled at nine centers and were randomly assigned to receive 10 days of treatment with cefuroxime axetil 250 mg twice daily (n = 157) or amoxicillin/clavulanate 500 mg three times daily (n = 160). Patients were assessed for both clinical and bacteriologic responses once during treatment (5 to 7 days) and twice after treatment (1 to 3 days and 4 weeks). Bacteriologic assessments were based on needle aspirates of the maxillary sinus obtained pretreatment and, when possible, at the first posttreatment visit.. Organisms were isolated from the pretreatment sinus aspirates of 198 of 317 (62%) patients, with the primary isolates being Streptococcus pneumoniae (22%), Haemophilus spp. (17%), Staphylococcus aureus (13%), and Haemophilus influenzae (10%). A satisfactory clinical outcome (cure or improvement) was achieved in 85% (98 of 115) and 82% (102 of 124) of the clinically evaluable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.446). With respect to the eradication of the bacterial pathogens, a satisfactory outcome (cure or presumed cure) was obtained in 84% (31 of 37) and 87% (34 of 39) of bacteriologically evaluable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (p = 0.567). Treatment with amoxicillin/clavulanate was associated with a significantly higher incidence of drug-related adverse events (13% versus 3%, p = 0.001), particularly diarrhea (8% versus 1%, p = 0.001). Two patients in the cefuroxime axetil group and three patients in the amoxicillin/clavulanate group withdrew from the study due to adverse events.. Our results indicate that cefuroxime axetil twice a day is as effective as amoxicillin/clavulanate three times a day in the treatment of acute bacterial maxillary sinusitis but produces fewer adverse effects.

Acute bacterial maxillary sinusitis: results of U.S. and European comparative therapy trials.
    The American journal of medicine, 1992, Jun-22, Volume: 92, Issue:6A

    Loracarbef, which is the first agent of the carbacephem class of beta-lactam antibiotics to be developed, provides good activity against a broad spectrum of bacteria. A single-blinded, randomized, parallel clinical trial in 10 centers in the United States compared the efficacy and safety of loracarbef with that of amoxicillin/clavulanate potassium in the treatment of acute bacterial maxillary sinusitis. A 7-10-day regimen of loracarbef (400 mg twice daily) was as effective as amoxicillin/clavulanate (500/125 mg three times a day) and resulted in somewhat fewer side effects. The results of a European trial in Sweden, Finland, and Iceland showed that loracarbef was clinically more effective than doxycycline in the treatment of acute bacterial maxillary sinusitis.

    Bisphosphonates (BPs) are widely used as bone-stabilizers, but side effects of BP therapy include bisphosphonate-related osteonecrosis of the jaw (BRONJ), which is resistant to therapy. The aim of this study was to evaluate the outcome of maxillary BRONJ involving sinusitis maxillaris. 21 patients presenting with maxillary BRONJ, from 2005 to 2008, were included in the study. In 18 cases BP had been administered for carcinoma and in 3 cases for osteoporosis, with an average exposure time of 47.4 months. 12 patients spontaneously developed BRONJ. The 10 patients diagnosed with stage III BRONJ presented with concomitant sinusitis maxillaris. Despite treatment, there were six recurrences of BRONJ, four of them with additional sinusitis maxillaris. Whether BRONJ occurred spontaneously or after extraction there was no difference in the outcome. Patients with advanced maxillary BRONJ often suffer from sinusitis maxillaris, both of which are frequently resistant to therapy.

    The purpose of this study was to evaluate the prognosis and treatment of infection of the maxillary sinus associated with dental implants.. Oral and radiographic general clinical features of 2 patients who developed maxillary sinusitis after implant placement.. The symptoms of maxillary sinusitis were improved by curettage through the lateral wall of the maxillary sinus, antibiotics, and sinus irrigation after 2 weeks of the operation.. It was concluded that acute maxillary sinusitis should be treated with a direct approach to the maxillary sinus via lateral wall opening, regular irrigation in hospital, and antibiotics.

Orbital complications due to an acute odontogenic focus in a child. A case report.
    Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics, 2009, Volume: 107, Issue:1

    The full clinical manifestations of complications due to odontogenic foci are rarely seen in daily dental practice and can take a clinically foudroyant course of development in young people owing to anatomic conditions, as demonstrated in this clinical case in a 12-year-old girl. Endodontic treatment of the first right upper molar was started owing to increasing toothache and swelling of fossa canina and the periorbital region. During the course of treatment, the patient exhibited an acute increase in orbital inflammation, which required immediate surgical intervention with postsurgical intravenous antibiotic administration. This case should serve to emphasize the crucial requirement for intensive attention to orbital symptoms after dental procedures.

The "dome phenomenon" associated with maxillary sinus augmentation.
    Clinical implant dentistry and related research, 2009, Volume: 11 Suppl 1

    This case series is aimed to report a new phenomenon, the "dome phenomenon," which was observed in infected augmented sinuses over several years.. Five patients are presented in whom sinus lift augmentation resulted in postoperative infection with inflammation and suppuration. The patients received aggressive anti-inflammatory treatment and surgical debridement of the inflamed tissue, including some grafted material performed through the lateral window of the primary procedure.. The inflammatory condition was reversed, and the site healed clinically. Radiographically, a dome-shaped, radio-opaque tissue was observed at the superior most aspect of the grafted sinus. This "dome phenomenon" was further confirmed during dental implant placement, which indicates healing potential adjacent to the maxillary sinus membrane.. The current report, as well as other studies and case series, suggests that there is great potential for healing and bone formation in the maxillary sinus membrane. The precise mechanism is not known. Further clinical and histologic studies are needed to understand the regenerative potential of the Schneiderian membrane.

Nasal septal abscess complicated with acute sinusitis and facial cellulitis in a child.
    Auris, nasus, larynx, 2007, Volume: 34, Issue:2

    Non-traumatic nasal septal abscess is rare, commonly seen in patients with poor immunity, and presents as isolated nasal septal abscess. Further, nasal septal abscess complicated with acute sinusitis is rather rare. Very little literature has been generated for non-traumatic nasal septal abscess complicated with acute sinusitis in healthy patients. Prompt diagnosis and adequate treatment will help to prevent the complications associated with nasal septal abscess such as saddle nose and intracranial involvement. Herein, to our knowledge, we present the first case involving an otherwise healthy little girl with nasal septal abscess complicated with acute sinusitis and facial cellulitis.

Bacteriological findings and antimicrobial susceptibility in chronic sinusitis with nasal polyp.

    We recommend amoxacillin/clavulanate, cephalosporins and macrolides rather than penicillin as the first-line drug in chronic sinusitis with nasal polyps. In cases where there is no improvement of symptoms, cultures should be taken from the middle meatus, followed by appropriate selection of second-line antibiotics according to the sensitivity test results.. To investigate the causative bacteria and the antimicrobial susceptibility in patients with chronic sinusitis and nasal polyps in Korea.. The bacteriology and antimicrobial susceptibility of maxillary sinus aspirates from 81 patients were evaluated.. Aerobes were isolated from 58.0% of the cultures from the middle meatus and from 48.1% of those from the maxillary sinus. Staphylococcus aureus, Haemophilus influenzae, and Streptococcus pneumoniae were the most prevalent aerobic pathogens. Anaerobes were isolated from 8.6% of the cultures from the middle meatus and from 18.5% of the cultures from the maxillary sinus. The predominant anaerobic organisms were Prevotella and Peptostreptococcus in adults but none of them were cultured in children. A high rate of concordance of the middle meatus and maxillary sinus was noted. Monomicrobial infection was most commonly observed. Ampicillin-resistant H. influenzae isolates were cultured in 46% of the cases. Penicillin resistance rates were 93% for Staph. aureus; 25% of Strep. pneumoniae were intermediate and 25% were resistant.

Abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar.
    International endodontic journal, 2006, Volume: 39, Issue:8

    To discuss a rare, but severe complication arising following routine root canal treatment.. An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the orbit was established and a high dose of perioperative antibiotics (Amoxicillin/Clavulanic acid, Gentamycin, Metronidazole) were administered. Vision remained undisturbed and mobility of the globe recovered within 10 days.. Rapid exacerbation of a periapical inflammation may occur following root canal treatment and may even involve the orbit. A typical speed of disease progression or ophthalmic symptoms should alert the clinician to at least consider unusual early orbital spread of odontogenic infection. When extra-alveolar spread and especially orbital spread is suspected, immediate referral to a maxillofacial or other specialized unit is mandatory.

Eradication of pathogens from the nasopharynx after therapy of acute maxillary sinusitis with low- or high-dose amoxicillin/clavulanic acid.
    International journal of antimicrobial agents, 2005, Volume: 26, Issue:5

    The growing resistance of Streptococcus pneumoniae to penicillin can be overcome by increasing the dose of the penicillin administered. This generated the recommendation that the adult dose of amoxicillin for the treatment of acute maxillary sinusitis (AMS) be increased from 1.5 g/day to 4.0 g/day. The objective of this study was to investigate whether the higher dose of amoxicillin is more effective than the previously recommended dose in eradicating S. pneumoniae from the nasopharynx of patients who present with AMS. Nasopharyngeal cultures obtained from 58 patients with AMS were studied: 30 received amoxicillin 1.5 g/day given in divided doses three times a day for 10 days (amoxicillin/clavulanic acid 4:1 formulation) and 28 were treated with amoxicillin 4.0 g/day given in divided doses twice a day for 10 days (amoxicillin/clavulanic acid 16:1 formulation). Seventy-one potentially pathogenic organisms were isolated: S. pneumoniae (27 isolates), Haemophilus influenzae non-type b (25), Moraxella catarrhalis (5), Streptococcus pyogenes (5) and Staphylococcus aureus (9). The number of S. pneumoniae isolates in the 1.5 g/day group was reduced from 14 to 9 (2 intermediately resistant and 3 highly resistant). In contrast, the number of S. pneumoniae isolates in the 4.0 g/day group was reduced from 13 to 2 (1 highly resistant) (P<0.05). No differences were noted in the eradication rate of other groups of isolates, which were all susceptible to amoxicillin/clavulanic acid. These data illustrate the superiority of 4.0 g/day amoxicillin/clavulanic acid compared with 1.5 g/day amoxicillin/clavulanic acid in the eradication of S. pneumoniae from the nasopharynx.

    The effect on the nasopharyngeal flora of 7 days of amoxicillin-clavulanate or 5 days of 800 mg once a day was studied in 50 adults with acute sinusitis. The numbers of potential pathogens and interfering alpha-hemolytic streptococci were equally reduced after both therapies. However, the number of interfering Prevotella spp. declined more significantly after amoxicillin-clavulanate treatment.

Sinusitis as a source of dental pain.
    Dentistry today, 2003, Volume: 22, Issue:9

    Sinusitis is a common medical problem that can occasionally manifest as dental pain. If the patient is experiencing dental pain in the maxillary posterior teeth, then it is appropriate for the dentist to rule out sinusitis as a source of the problem before proceeding with definitive dental treatment. Often there is an obvious odontogenic source of the pain, and this should be resolved first, but in other situations it is difficult to determine the cause of the symptoms. In some patients, the source of the pain is so equivocal that it may be necessary to treat the patient for sinusitis to eliminate this as the source of the dental pain (Table 7). In this process, the dentist has one of 2 options: either refer the patient to a physician or treat the sinusitis. The option chosen regarding patient management is made by the dentist and depends on the particular clinical situation and the dentist's training and experience.

    The drug sensitiveness to beta-lactam antibiotics of the bacterial flora, taken by sinus puncture from 115 patients with unior bilateral acute exacerbation of chronic maxillary sinusitis was analysed. About 90% of the isolated pathogens, as well as in subgroup treated with amoxicillin with potassium clavulanate and in subgroup treated with cefuroxime axetil showed antibiotic sensitivity. Among isolated pathogens before the treatment, 4 (9.5%) were resistant to the amoxicillin with potassium clavulanate disks in subgroup A and 3 (7.3%) to the cefuroxime axetil in subgroup B. There was only one pathogen isolated in the control evaluation in both group after the treatment.

A fatal case of necrotizing sinusitis due to toxigenic Corynebacterium ulcerans.
    International journal of medical microbiology : IJMM, 2002, Volume: 292, Issue:1

    A 77-year-old farmer developed cough with sputum production, fever, bloody nasal discharge and a mass in his right maxillary sinus leading to necrotic ulceration of the sinus. Corynebacterium ulcerans, carrying the beta-phage for the diphtheria toxin and secreting the toxin, was detected microscopically and by culture from the sinusoidal and ulcer discharge. Despite immediate antimicrobial chemotherapy the patient died of pulmonary failure associated with the production of large amounts of very viscous sputum. Identification of the causative agent, pathophysiological aspects and risk factors of this unusal infection are discussed.

    An open-label, multicenter study was performed to assess bacteriologic findings associated with chronic bacterial maxillary sinusitis in adults. Seventy aerobic (52.2%) and 64 anaerobic (47.8%) pathogens were recovered from clinically evaluable patients at baseline (before therapy). The most commonly isolated anaerobes were Prevotella species (31.1%), anaerobic streptococci (21.9%), and Fusobacterium species (15.6%). The aerobes most frequently recovered included Streptococcus species (21.4%), Haemophilus influenzae (15.7%), Pseudomonas aeruginosa (15.7%), and Staphylococcus aureus and Moraxella catarrhalis (10.0% each). Recurrences of signs or symptoms of bacterial maxillary sinusitis associated with anaerobes were twice as frequent as were those associated with aerobes when counts of anaerobes were > or =10(3) cfu/mL. A pathogenic role for Granulicatella species in cases of chronic sinusitis was documented for the first time.

[Efficient antibiotic therapy in radical surgery on the maxillary sinus].
    Vestnik otorinolaringologii, 2002, Issue:4

    The study assessed efficiency of local antibiotic therapy with mupirocin and amoxicillin/clavulanate in 28 patients radically operated on the maxillary sinus (MS). Early after the operation, MS tamponing with a latex tampon was made. The tampon was filled with mupirocin for patients of group 1. In patients of group 2 and controls the tampon was sterile but in group 2 after the tampon removal postoperative maxillary washing was made with amoxicillin/clavulanate solution. The results of the study demonstrated high efficiency of local administration of mupirocin and amoxicillin/clavulanate and validity of bacteriological examination in planning antibiotic therapy early after surgery.

Transnasal endoscopic drainage of a medial subperiosteal orbital abscess.

    The exact incidence of orbital complications due to sinusitis in children is unknown. However, a medial subperiosteal orbital abscess is the most common serious complication to occur. Surgical intervention is mandatory whenever antibiotic treatment fails. Most authors prefer open surgical procedures such as external ethmoidectomy, while others recommend transnasal endoscopic drainage as the first attempt at sinus decompression. Five out of 12 children with proven subperiosteal orbital abscess and sinusitis on computed tomographic scans failed antibiotic treatment and required surgical drainage. Transnasal endoscopic drainage of the abscess was performed on four patients, while one child underwent external ethmoidectomy. Our experience with endoscopic surgery in these four cases is discussed, along with a brief review of the advantage of this procedure over external surgery.

Effect of antibiotic therapy on nasal nitric oxide concentration in children with acute sinusitis.
    American journal of respiratory and critical care medicine, 1997, Volume: 155, Issue:5

    Recently, it has been demonstrated that paranasal sinuses are an important site of nitric oxide (NO) production in the upper airways. The aim of this study was to evaluate the NO nasal concentration in children with acute maxillary sinusitis before and after treatment with antibiotic therapy. We performed NO nasal measurements in 16 children 4 to 13 yr of age with acute maxillary sinusitis and compared values with 16 age- and sex-matched healthy control subjects. The diagnosis of acute sinusitis was done by clinical signs and symptoms in addition to radiographic examination. NO nasal concentrations were measured by a chemiluminescence analyzer. Nasal NO steady state during oral breathing was recorded. The mean +/- SEM NO nasal concentration in children with sinusitis was 70 +/- 8.7 parts per billion (ppb) and increased significantly to 220 +/- 15 ppb (p < 0.001) after antibiotic therapy (amoxicillin/clavulanate). NO values after recovery from sinusitis were similar to those of healthy control subjects (245 +/- 15 ppb, p = NS). NO nasal measurements were also performed before and after antibiotic treatment in nine children 4 to 12 yr of age with symptoms of upper respiratory tract infection but no symptoms of sinusitis. In these children NO nasal levels were 249 +/- 32 ppb and did not change (p = NS) after antibiotic therapy. We conclude that during acute maxillary sinusitis the concentration of nasal NO is largely decreased, probably because of an impaired flow of NO from the paranasal sinuses, and that NO returns to normal levels after antibiotic therapy.
