Antibiotics for clinically diagnosed acute rhinosinusitis in adults

In primary care settings, the diagnosis of rhinosinusitis is generally based on clinical signs and symptoms. Technical investigations are not routinely performed, nor recommended. Individual trials show a trend in favour of antibiotics, but the balance of benefit versus harm is unclear. To assess the effect of antibiotics in adults with clinically diagnosed rhinosinusitis in primary care settings. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2012), MEDLINE (January 1950 to February week 4, 2012) and EMBASE (January 1974 to February 2012). Randomised controlled trials (RCTs) of antibiotics versus placebo in participants with rhinosinusitis-like signs or symptoms. Two authors independently extracted data and assessed the risk of bias. We contacted trial authors for additional information. We collected information on adverse effects from the trials. We included 10 trials involving 2450 participants. Overall, the risk of bias in these studies was low. Irrespective of the treatment group, 47% of participants were cured after one week and 71% after 14 days. Antibiotics can shorten the time to cure, but only five more participants per 100 will cure faster at any time point between 7 and 14 days if they receive antibiotics instead of placebo (number needed to treat to benefit (NNTB)) 18 (95% confidence interval (CI) 10 to 115, I(2) statistic 0%, eight trials). Purulent secretion resolves faster with antibiotics (odds ratio (OR) 1.58 (95% CI 1.13 to 2.22)), (NNTB 11, 95% CI 6 to 51, I(2) statistic 0%, three trials). However, 27% of the participants who received antibiotics and 15% of those who received placebo experienced adverse events (OR 2.10, 95% CI 1.60 to 2.77) (number needed to treat to harm (NNTH)) 8 (95% CI 6 to 13, I(2) statistic 13%, seven trials). More participants in the placebo group needed to start antibiotic therapy because of an abnormal course of rhinosinusitis (OR 0.49, 95% CI 0.36 to 0.66), NNTH 20 (95% CI 14 to 35, I(2) statistic 0%, eight trials). Only one disease-related complication (brain abscess) occurred in a patient treated with antibiotics. The potential benefit of antibiotics in the treatment of clinically diagnosed acute rhinosinusitis needs to be seen in the context of a high prevalence of adverse events. Taking into account antibiotic resistance and the very low incidence of serious complications, we conclude that there is no place for antibiotics for the patient with clinically diagnosed, uncomplicated acute rhinosinusitis. This review cannot make recommendations for children, patients with a suppressed immune system and patients with severe disease, as these populations were not included in the available trials.

Pan‐American Clinical Guideline on Rhinosinusitis

ObjectiveThis evidence‐based clinical practice guideline (CPG) aims to improve clinical decision making of general practitioners and specialists in the treatment of acute and chronic rhinosinusitis in adults. Support clinicians in clinical decision making for medical treatment with target in the pathophysiological process and evidence‐based efficacy, safety, and tolerability.MethodThe Pan‐American Association of Otorhinolaryngology and Head and Neck Surgery, in partnership with the Ibero American Agency for Development and Assessment of Health Technologies, developed a clinical practice guideline on medical management of acute and chronic rhinosinusitis in adults. This document provides punctual evidence‐based recommendations for primary care physicians and otolaryngologists on the medical management of these conditions and complies with evidence‐based medicine fundamentals and with well‐validated guidelines methodology as recommended by the National Institute for Clinical Excellence, the National Institutes of Health, and The Scottish Intercollegiate Guidelines Network.ResultsThis document provides from A Grade to D Grade clinical recommendations for treatment of these conditions. The Guideline Development Group made recommendations based on well‐designed, randomized controlled trials and systematic reviews. Some clinical questions could not be answered by high quality research and for these questions a Panel Delphi was conducted to provide clinical guidance. Overall there is a need for well‐designed RCTs and economic assessments to answer most of the gaps of knowledge for the treatment of acute and chronic rhinosinusitis.ConclusionThis clinical practice guideline provides guidance for the medical treatment of adults with acute and chronic rhinosinusitis.

Assessment of Clinical Antimicrobial Garenoxacin (GRNX) Efficacy Using Clinical Scoring in Adults with Acute Rhinosinusitis

In a prospective study of rhinosinusitis treatment efficacy in 163 subjects at 30 medical facilities between 2008 and 2009, we studied isolation of three major pathogenic bacteria-Streptococcus pneumoniae, Haemophillus influenzae, and Moraxella catarrhalis. We also examined clinical garenoxacin (GRNX) efficacy in 106 acute rhinosinusitis cases and 57 acute chronic rhinosinusitis exacerbation cases using Japan Acute Rhinosinusitis Clinical Guideline 2010 clinical scoring. Isolation of S. pneumoniae was 50.0% (22/44), H. influenzae 43.2% (19/44), and M. catarrhalis 6.8% (3/44) in 106 acute rhinosinusitis subjects. Drug-resistant strains accounted for over 50% in S. pneumoniae and H. influenzae. Isolation of the three bacterial pathogens in 57 acute chronic rhinosinusitis exacerbation subjects was 50.0% (9/18) in S. pneumoniae, 27.8% (5/18) in H. influenzae, and 22.2% (4/18) in M. catarrhalis. Drug resistance exceeded 40% in S. pneumoniae and H. influenzae. In efficacy studies of 97 subjects, GRNX at 400 mg/day in 54 with acute rhinosinusitis was 100%—marked improvement in 51.9% (28/54) and moderate in 48.1% (26/54). Efficacy in 43 acute chronic rhinosinusitis exacerbation subjects was 95.3%—marked improvement in 79.1% (34/43) and moderate in 16.3% (7/43). These results show the usefulness of clinical scoring in diagnosing diseases severity and in studying the efficacy of antimicrobial agents. Data clearly indicated the high clinical and bacterial efficacy of garenoxacin in treating adult rhinosinusitis.

Revisión del tratamiento quirúrgico de la rinosinusitis

The aim of this revision paper is to provide an update of available resources to achieve the best endoscopic sinus surgery outcomes of adult rhinosinusitis. The cause and mechanisms of rhinosinusitis remain unknown, and curative treatment does not exist. Recent new insights into paranasal sinus pathophysiology, along with technical advances in imaging and endoscopy, have revolutionised surgical treatment of rhinosinusitis. Since an increasing number of patients undergo functional endoscopic sinus surgery as a therapeutic regimen for their disease, appropriate use of computed tomography is critical in providing a “roadmap” for the surgeon to delimit the surgical procedure, as well as to ensure safety and accuracy. With proper training and technique, endoscopic surgery is quite safe, but prevention and management of complications must be known.

Involving Stakeholders to Optimize a Study Protocol on Secondhand Tobacco Smoke and Chronic Rhinosinusitis in Adults

Epidemiological evidence evaluating the association between secondhand smoke exposure and diseases of the upper airway in adults is limited by a small number of studies and a lack of established protocols. This study was designed to optimize a research protocol on secondhand tobacco smoke exposure and chronic rhinosinusitis for a future population-based case-control study in Washington County, Maryland, using a participatory research model. We conducted three focus groups with health professionals, community members, and research practitioners for protocol development; 10 one-on-one cognitive testings with community members for protocol refinement; and a pilot testing of the full study protocol (10 cases and 10 controls) for full evaluation of the study protocol. Health professionals recommended, among other themes, enrolling patients with confirmed chronic rhinosinusitis (minimum 12-week symptom duration and objective inflammation). Community members and research practitioners discussed optimal strategies for participant recruitment and interviewing. The protocol, revised with the focus group's feedback, was further evaluated in one-on-one sessions with 10 Washington County residents (3 with chronic rhinosinusitis). In the pilot study, 10 nonsmoking chronic rhinosinusitis cases (5 clinic based and 5 community based) and their community-based age, sex, and former/never smoking-matched controls were recruited. Sinonasal symptoms scores were higher in cases than controls but similar for clinic versus community-based cases. This protocol development framework involving stakeholders resulted in a comprehensive questionnaire that was successfully evaluated during a pilot study and is now ready to be used in population-based and clinical epidemiological studies of chronic rhinosinusitis in adults.

Diagnosis and Management of Chronic Rhinosinusitis in Adults

Chronic rhinosinusitis (CRS) is characterized by mucosal inflammation affecting both the nasal cavity and paranasal sinuses; its causes are potentially numerous, disparate, and frequently overlapping. The more common conditions that are associated with CRS are perennial allergic and nonallergic rhinitis, nasal polyps, and anatomical mechanical obstruction (septum/turbinate issues). Other less common etiologies include inflammation (eg, from superantigens), fungal sinusitis or bacterial sinusitis with or without associated biofilm formation, gastroesophageal reflux, smoke and other environmental exposures, immune deficiencies, genetics, and aspirin-exacerbated respiratory disease. A diagnosis of CRS is strongly suggested by a history of symptoms (eg, congestion and/or fullness; nasal obstruction, blockage, discharge, and/or purulence; discolored postnasal discharge; hyposmia/anosmia; facial pain and/or pressure) and their duration for > 3 months. A definitive diagnosis requires physical evidence of mucosal swelling or discharge appreciated during physical examination coupled with CT imaging if inflammation does not involve the middle meatus or ethmoid bulla. Multivariant causation makes the diagnosis of CRS and selection of treatment complex. Furthermore, various types of health care providers including ear, nose, and throat (ENT) specialists, allergists, primary care physicians, and pulmonologists treat CRS, and each is likely to have a different approach. A structured approach to the diagnosis and management of CRS can help streamline and standardize care no matter where patients present for evaluation and treatment. A 2008 Working Group on CRS in Adults, supported by the American Academy of Otolaryngic Allergy (AAOA), developed a series of algorithms for the differential diagnosis and treatment of CRS in adults, based on the evolving understanding of CRS as an inflammatory disease. The algorithms presented in this paper address an approach for all CRS patients as well as approaches for those with nasal polyps, edema observed on nasal endoscopy, purulence observed on nasal endoscopy, an abnormal history and physical examination, and an abnormal history and normal physical examination.

The effect of acute rhinosinusitis on pulmonary function in adults

To evaluate the influence of acute rhinosinusitis on lung function as measured by spirometry. An observational study in Danish general practice on 25 adult patients with a clinical diagnosis of acute rhinosinusitis and without any signs of chronic lung disease or allergy. Patients performed spirometry at the initial acute visit and then eight weeks later when the rhinosinusitis had resolved. Eight weeks after the initial visit there was a significant increase in the maximum mid-expiratory flow (F25-75), and in peak flow. Acute rhinosinusitis in adults without any sign of chronic lung disease or allergy is accompanied by a temporary reduction in maximum mid-expiratory flow and peak flow. This may be caused by subclinical inflammation in the airways during acute rhinosinusitis. Further studies with extended lung function measurements are needed to evaluate and confirm this finding.

Efficacy of cefditoren pivoxil and amoxicillin/clavulanate in the treatment of pediatric patients with acute bacterial rhinosinusitis in Thailand: A randomized, investigator-blinded, controlled trial

Background: The recommended treatment for acute bacterial rhinosinusitis in adults and children is 10 to 14 days of high doses of oral cephalosporins or amoxicillin/clavulanate.Objective: This study compared the clinical efficacy and tolerability of cefditoren pivoxil and amoxicillin/ clavulanate in children with uncomplicated acute bacterial rhinosinusitis.Methods: This was a randomized, investigator-blinded, controlled study in pediatric patients (age 1–15 years) with clinical and radiographic signs and symptoms of acute rhinosinusitis. Patients were allocated to receive either cefditoren (8–12 mg/kg daily) or amoxicillin/clavulanate (80–90 mg/kg amoxicillin daily) for 14 days. Changes in sinus symptoms were assessed daily by patients or their parents using a quantitative symptom score (the S5 score). Rates of improvement, the primary efficacy measure, were also evaluated by the study investigators 7 and 14 days after the initial visit. Secondary outcome measures included time to improvement, adverse effects, and rates of relapse (assessed at days 21 and 28) and recurrence (assessed at day 60) of sinus symptoms. Relapse was defined as a subjective rating of lack of improvement at day 21 or 28 in a patient rated as improved on day 14, and recurrence was defined as sinus symptoms lasting for ≥10 days during the second month of follow-up in a patient rated as improved on day 28. Time to improvement was defined as the number of days between the initial visit and the time at which caregivers noted an improvement in patients' symptoms. Adverse events were monitored by parents/caregivers using a self-administered questionnaire and were also elicited by telephone contact.Results: The study enrolled 142 pediatric patients: 70 in the cefditoren group (42 males, 28 females; median age, 7.15 years) and 72 in the amoxicillin/clavulanate group (37 males, 35 females; median age, 6.60 years). Four patients in the cefditoren group were excluded from the study analyses (2 who were noncompliant [used <80% of the assigned medication] and 2 who developed infection at other sites). There were no significant differences in baseline medical history or signs and symptoms between the 2 groups. Rates of improvement at day 14 in the cefditoren and amoxicillin/clavulanate groups were 78.8% (52/66) and 84.7% (61/72), respectively (P = NS). There was no significant difference in the change in S5 scores between groups at day 14. The median time to improvement was 3.0 days in both groups. There were no significant differences between groups in rates of relapse (9.1% and 11.1%) or recurrence (3.0% and 5.6%) of sinus symptoms. The most common adverse event in both groups was diarrhea, occurring in 4.5% of the cefditoren group and 18.1 % of the amoxicillin/clavulanate group (P = 0.02).Conclusion: In these children with acute bacterial rhinosinusitis, there were no significant differences between cefditoren and amoxicillin/clavulanate, the currently recommended treatment, in terms of rates of response, relapse, or recurrence.

Clinical practice guideline: Adult sinusitis

This guideline provides evidence-based recommendations on managing sinusitis, defined as symptomatic inflammation of the paranasal sinuses. Sinusitis affects 1 in 7 adults in the United States, resulting in about 31 million individuals diagnosed each year. Since sinusitis almost always involves the nasal cavity, the term rhinosinusitis is preferred. The guideline target patient is aged 18 years or older with uncomplicated rhinosinusitis, evaluated in any setting in which an adult with rhinosinusitis would be identified, monitored, or managed. This guideline is intended for all clinicians who are likely to diagnose and manage adults with sinusitis. The primary purpose of this guideline is to improve diagnostic accuracy for adult rhinosinusitis, reduce inappropriate antibiotic use, reduce inappropriate use of radiographic imaging, and promote appropriate use of ancillary tests that include nasal endoscopy, computed tomography, and testing for allergy and immune function. In creating this guideline the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of allergy, emergency medicine, family medicine, health insurance, immunology, infectious disease, internal medicine, medical informatics, nursing, otolaryngology-head and neck surgery, pulmonology, and radiology. The panel made strong recommendations that 1) clinicians should distinguish presumed acute bacterial rhinosinusitis (ABRS) from acute rhinosinusitis caused by viral upper respiratory infections and noninfectious conditions, and a clinician should diagnose ABRS when (a) symptoms or signs of acute rhinosinusitis are present 10 days or more beyond the onset of upper respiratory symptoms, or (b) symptoms or signs of acute rhinosinusitis worsen within 10 days after an initial improvement (double worsening), and 2) the management of ABRS should include an assessment of pain, with analgesic treatment based on the severity of pain. The panel made a recommendation against radiographic imaging for patients who meet diagnostic criteria for acute rhinosinusitis, unless a complication or alternative diagnosis is suspected. The panel made recommendations that 1) if a decision is made to treat ABRS with an antibiotic agent, the clinician should prescribe amoxicillin as first-line therapy for most adults, 2) if the patient worsens or fails to improve with the initial management option by 7 days, the clinician should reassess the patient to confirm ABRS, exclude other causes of illness, and detect complications, 3) clinicians should distinguish chronic rhinosinusitis (CRS) and recurrent acute rhinosinusitis from isolated episodes of ABRS and other causes of sinonasal symptoms, 4) clinicians should assess the patient with CRS or recurrent acute rhinosinusitis for factors that modify management, such as allergic rhinitis, cystic fibrosis, immunocompromised state, ciliary dyskinesia, and anatomic variation, 5) the clinician should corroborate a diagnosis and/or investigate for underlying causes of CRS and recurrent acute rhinosinusitis, 6) the clinician should obtain computed tomography of the paranasal sinuses in diagnosing or evaluating a patient with CRS or recurrent acute rhinosinusitis, and 7) clinicians should educate/counsel patients with CRS or recurrent acute rhinosinusitis regarding control measures. The panel offered as options that 1) clinicians may prescribe symptomatic relief in managing viral rhinosinusitis, 2) clinicians may prescribe symptomatic relief in managing ABRS, 3) observation without use of antibiotics is an option for selected adults with uncomplicated ABRS who have mild illness (mild pain and temperature <38.3 degrees C or 101 degrees F) and assurance of follow-up, 4) the clinician may obtain nasal endoscopy in diagnosing or evaluating a patient with CRS or recurrent acute rhinosinusitis, and 5) the clinician may obtain testing for allergy and immune function in evaluating a patient with CRS or recurrent acute rhinosinusitis. This clinical practice guideline is not intended as a sole source of guidance for managing adults with rhinosinusitis. Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Faropenem medoxomil: a treatment option in acute bacterial rhinosinusitis

Faropenem medoxomil is the first oral penem in a new class of β-lactam antibiotics. Faropenem medoxomil has excellent in vitro activity against Streptococcus pneumoniae, Haemophilus influenzae and other key pathogens implicated in acute bacterial rhinosinusitis. Clinical studies have demonstrated that, in the treatment of acute bacterial rhinosinusitis in adults, 7 days of treatment with faropenem medoxomil is as clinically and bacteriologically effective as 10 days of treatment with cefuroxime axetil. One study showed faropenem medoxomil to be superior to cefuroxime axetil. Overall, the safety profile of faropenem medoxomil is similar to that of most comparators. Specifically, the minimal impact of faropenem medoxomil on the gastrointestinal flora leads to less diarrhea and other adverse events than coamoxicillin–clavulanate. Faropenem medoxomil has almost no drug–drug interactions and little requirement for dosage adjustments in the typical acute rhinosinusitis population.

Immunoglobulins and complement factor C4 in adult rhinosinusitis

We assessed whether complement and its factor C4 or abnormal immunoglobulin levels are associated with chronic or recurrent rhinosinusitis. We used multiple patient and control groups to obtain clinically meaningful data. Adult chronic or recurrent rhinosinusitis and acute purulent rhinosinusitis patients were compared with unselected adults and controls without previous rhinosinusitis. Associated clinical factors were reviewed. Levels of immunoglobulins, plasma C3, C4 and classical pathway haemolytic activity were analysed. C4 immunophenotyping was used to detect C4A and C4B deficiencies as null alleles. Complement was up-regulated in rhinosinusitis. C4A nulls and low IgA, IgG, IgG1, IgG2, IgG3 and IgG4 levels were all more common in chronic or recurrent rhinosinusitis patients than in unselected and healthy controls. We searched for relevant differences between the patient groups. According to stepwise logistic regression analysis, nasal polyposis [odds ratio (OR) 10.64, 95% confidence interval (CI) 2.5-45.7, P = 0.001], bronchial asthma (OR 8.87, 95% CI 2.3-34.9, P = 0.002), C4A null alleles (OR 5.84, 95% CI 1.4-24.9, P = 0.017) and low levels of IgG4 together with either IgG1 or IgG2 (OR 15.25, 95% CI 1.4-166.8, P = 0.026) were more common in chronic or recurrent rhinosinusitis than in acute rhinosinusitis patients. Isolated low IgG subclasses had limited value in patient assessment. C4A null alleles are associated with chronic or recurrent rhinosinusitis, potentially through their effect on immune defence and inflammation control. Multiple clinical and immunological parameters may need to be evaluated when searching for prognostic variables.

CPD: Acute Bacterial Rhinosinusitis in Adults: Part I. Evaluation.

Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory practice. Although often caused by viruses, it sometimes is caused by bacteria, a condition that is called acute bacterial rhinosinusitis. The signs and symptoms of acute bacterial rhinosinusitis and prolonged viral upper respiratory infection are similar, which makes accurate clinical diagnosis difficult. South African Family Practice Vol. 47(6) 2005: 22-27

An open multicenter study of the use of gatifloxacin for the treatment of non-complicated acute bacterial rhinosinusitis in adults

The bacteriological and clinical efficacy and the safety of gatifloxacin for the treatment of non-complicated acute rhinosinusitis was evaluated in 49 adult patients in an open-label multicenter study in Brazil. Patients under age 18, or with associated systemic diseases, were excluded. Diagnosis was based on symptoms, otorhinolaryngological examination, and X-rays of the sinus. At the first visit, all patients were treated with a single daily dose of 400 mg gatifloxacin for 10 days. Middle nasal meatus secretion was collected and sent for culture before and after treatment. Patients were all reevaluated at days 3 to 5; days + 1 to + 5 and 18 to 25 days + 7 to + 14 . Ninety three percent of the patients were considered clinically cured at the end of the treatment. The most frequent bacteria isolated were Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis, and at the end of the treatment, presumed bacteriological eradication was observed in almost all patients. Adverse effects were observed in 19 of the cases, mostly mild and self limiting, including diarrhea, abdominal pain, nausea and vomiting. Treatment had to be interrupted in two cases. Gatifloxacin was found to be efficacious and safe for the treatment of acute rhinosinusitis in adults.

Endoscopic sinus surgery in patients older than sixty

Rhinosinusitis is the sixth most common chronic condition of the elderly. Functional endoscopic sinus surgery (FESS) has developed over the last 20 to 30 years into a widely accepted treatment modality for chronic rhinosinusitis in adults who have failed maximal medical management. The aim of this study was investigate the safety and efficacy of FESS in the geriatric population as compared to that of the adult population. Retrospective review of prospective measurement of outcomes in consecutive patients over 60 years of age who underwent FESS. Fifty-six patients over 60 years of age underwent FESS and were evaluated preoperatively and postoperatively at 3, 6, and 12 months with the Sino-Nasal Outcome Test-20 (SNOT-20) questionnaire, and a rigid nasal endoscopy scoring system. Data analysis was performed using the Student's t test to compare mean scores. Any complications were noted. Patients evaluated by the SNOT-20 scoring system experienced 64% improvement of symptom scores at 3 months, 73% improvement at 6 months, and 75% improvement at 12 months. Rigid nasal endoscopy scores improved by 76% at 3 months, 65% at 6 months, and 76% at 12 months. There were very few minor complications and no major complications of the surgery. These results are comparable to those of the literature that address outcomes in the adult population undergoing FESS. FESS in the geriatric population is a safe and effective treatment modality for rhinosinusitis that is refractory to medical therapy. C.

Principles of appropriate antibiotic use for acute rhinosinusitis in adults: Background

The following principles of appropriate antibiotic use for adults with acute rhinosinusitis apply to the diagnosis and treatment of acute maxillary and ethmoid rhinosinusitis in adults who are not immunocompromised.1.Most cases of acute rhinosinusitis diagnosed in ambulatory care are caused by uncomplicated viral upper respiratory tract infections.2.Bacterial and viral rhinosinusitis are difficult to differentiate on clinical grounds. The clinical diagnosis of acute bacterial rhinosinusitis should be reserved for patients with rhinosinusitis symptoms lasting 7 days or more who have maxillary pain or tenderness in the face or teeth (especially when unilateral) and purulent nasal secretions. Patients with rhinosinusitis symptoms that last less than 7 days are unlikely to have bacterial infection, although rarely some patients with acute bacterial rhinosinusitis present with dramatic symptoms of severe unilateral maxillary pain, swelling, and fever.3.Sinus radiography is not recommended for diagnosis in routine cases.4.Acute rhinosinusitis resolves without antibiotic treatment in most cases. Symptomatic treatment and reassurance is the preferred initial management strategy for patients with mild symptoms. Antibiotic therapy should be reserved for patients with moderately severe symptoms who meet the criteria for the clinical diagnosis of acute bacterial rhinosinusitis and for those with severe rhinosinusitis symptoms—especially those with unilateral facial pain—regardless of duration of illness. For initial treatment, the most narrow-spectrum agent active against the likely pathogens, Streptococcus pneumoniae and Haemophilus influenzae, should be used.[Hickner JM, Bartlett JG, Besser RE, Gonzales R, Hoffman JR, Sande A.
