Intranasal budesonide spray as an adjunct to oral antibiotic therapy for acute sinusitis in children

The updated role of budesonide in managing children and adolescents with allergic rhinitis

Allergic rhinitis (AR) is a prevalent disease in childhood and adolescence. A type 2 inflammation characterizes AR and, mainly, sustains nasal obstruction. Budesonide aqueous nasal spray (BANS) is an intranasal corticosteroid (INCS) available since the early 1980s. BANS is indicated for treating allergic rhinitis. There is evidence about its efficacy in treating children and adolescents with seasonal and perennial AR. In addition, BANS is safe with negligible local and systemic side effects. Recent guidelines for patients with AR recommend the use of INCS as first line in many situations. In particular, AR patients (and their parents) may assess the perception of symptoms' severity using the Visual Analog Scale (VAS). A score ≥5/10 means uncontrolled symptoms and requires adequate treatment. BANS could appropriately be used in patients with uncontrolled symptoms and/or moderate/severe nasal obstruction. In conclusion, BANS represents a valuable option in managing children and adolescents with AR.

Sinusitis in Children

Acute bacterial sinusitis (ABS) mostly occurs as a complication of acute viral upper respiratory tract infection (URI), which is a common condition encountered in an outpatient setting. ABS manifests with three different presentations, most commonly as persistent symptoms of viral URI (nasal drainage and or cough) for more than 10 days. ABS is also diagnosed when the patient presents with severe symptoms of a URI accompanied by fever >102.2°F and purulent nasal drainage for at least 3 days. Lastly, ABS can complicate viral URI around day 6 or 7 of illness after initial improvement in the symptoms of URI. Imaging studies are not recommended for diagnosing ABS, unless intracranial or orbital complications are suspected. Signs of proptosis, restriction of eye movements, ophthalmoplegia, and visual impairment are very specific for orbital involvement. Treatment of ABS with antibiotics is recommended based on the clinical scenario and has been shown to have higher cure rates as compared to placebo. [Pediatr Ann. 2018;47(10):e396-e401.].

Topical Antibiotic, Antifungal, and Antiseptic Solutions Decrease Ciliary Activity in Nasal Respiratory Cells

This study was designed to investigate whether topical solutions, as they are used in the treatment of selected cases of rhinosinusitis, influence nasal mucociliary clearance. The objective of this study was to evaluate the effects of the following topical solutions on the ciliary beat frequency (CBF) of nasal respiratory cells: ofloxacin as an antibiotic; Betadine and hydrogen peroxide (H2O2) as antiseptic; and amphotericin B, itraconazole, and clotrimazole as antifungal solutions. Differences are described between effects of each of these substances and we clarify whether ciliotoxic effects are dose dependent and if they can be reduced or eliminated by diluting the concentration of the applied solution. In a prospective study, nasal respiratory cells were harvested from healthy individuals and CBF was measured while cells were perfused with cell culture medium and the respective topical solution, using a Dvorak/Stotler exposure chamber. Controls were perfused with cell culture medium only. Video interference contrast microscopy was used to monitor CBF. A decrease of CBF occurred after application of all topical solutions used in this study. Except for clotrimazole, all solutions showed significantly stronger effects at high concentrations compared with diluted solutions. Our results indicate that topical application of antifungal, antibiotic, and antiseptic solutions may cause a marked impairment of mucociliary clearance. The strong dose dependence of these ciliotoxic effects indicates the need for a careful selection of the adequate concentration when using topical treatment in the nose.

Update on Intranasal Medications in Rhinosinusitis

This review describes beneficial effects and adverse events of various intranasal medications in treating rhinosinusitis. Application of intranasal steroids has been described in treating all subtypes of adult rhinosinusitis, but reports are limited in pediatrics and mostly in acute pediatric subgroups resulted in benefits While saline irrigation is effective for patients with chronic rhinosinusitis without polyps and in pediatric acute rhinosinusitis, there is no evidence yet for saline drips and sprays. Application of intranasal antifungals and nasal irrigation with surfactant brings more harm than benefits. There is no evidence supporting the use of intranasal antibiotics. We also review influence of devices, methods, and patient head position on nasal and paranasal sinus drug delivery.

Comparative study of the efficacy of topical steroid and antibiotic combination therapy versus oral antibiotic alone when treating acute rhinosinusitis

Background:

Acute rhinosinusitis arises as a consequence of viral rhinitis, and bacterial infection can subsequently occur. Intranasal antibiotics as an adjunct to corticosteroids usually demonstrate the greatest symptom relief.

Aim:

We wanted to clinically evaluate the effects of a topical antibiotic and steroid combination administered intranasally, versus an oral antibiotic alone when treating acute rhinosinusitis.

Method:

Forty patients with acute bacterial rhinosinusitis were divided into two groups. Group A received an antibiotic and steroid combination (ofloxacin 0.26 per cent and dexamethasone 0.053 per cent nasal drops) for 10 days, administered intranasally (5 drops in each nostril/8 hours). Group B, the control group, received an oral antibiotic alone (amoxicillin 90 mg/kg).

Results:

Eight hours after commencing treatment, facial pain was more severe in group B and nasal obstruction was reduced in both groups. Ten days after commencing treatment, anterior nasal discharge was 0.15 per cent in group A and absent in group B.

Conclusion:

The application of a topical antibiotic and steroid combination into the nasal cavity is an effective way of treating uncomplicated, acute bacterial rhinosinusitis with the theoretical advantages of easy administration, high local drug concentration and minimal systemic adverse effects.

Decongestants, antihistamines and nasal irrigation for acute sinusitis in children

BACKGROUND

The efficacy of decongestants, antihistamines and nasal irrigation in children with clinically diagnosed acute sinusitis has not been systematically evaluated.

OBJECTIVES

To determine the efficacy of decongestants, antihistamines or nasal irrigation in improving symptoms of acute sinusitis in children.

SEARCH METHODS

We searched CENTRAL (2014, Issue 5), MEDLINE (1950 to June week 1, 2014) and EMBASE (1950 to June 2014).

SELECTION CRITERIA

We included randomized controlled trials (RCTs) and quasi-RCTs, which evaluated children younger than 18 years of age with acute sinusitis, defined as 10 to 30 days of rhinorrhea, congestion or daytime cough. We excluded trials of children with chronic sinusitis and allergic rhinitis.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed each study for inclusion.

MAIN RESULTS

Of the 662 studies identified through the electronic searches and handsearching, none met all the inclusion criteria.

AUTHORS' CONCLUSIONS

There is no evidence to determine whether the use of antihistamines, decongestants or nasal irrigation is efficacious in children with acute sinusitis. Further research is needed to determine whether these interventions are beneficial in the treatment of children with acute sinusitis.

Intranasal steroids for acute sinusitis

BACKGROUND

Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school.

OBJECTIVES

We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis in adults and children.

SEARCH METHODS

We searched CENTRAL 2013, Issue 4, MEDLINE (January 1966 to May week 2, 2013), EMBASE (1990 to May 2013) and bibliographies of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing INCS treatment to placebo or no intervention in adults and children with acute sinusitis. Acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data, assessed trial quality and resolved discrepancies by consensus.

MAIN RESULTS

No new trials were found for inclusion in this update. Four studies involving 1943 participants with acute sinusitis met our inclusion criteria. The trials were well-designed and double-blind and studied INCS versus placebo or no intervention for 15 or 21 days. The rates of loss to follow-up were 7%, 11%, 41% and 10%. When we combined the results from the three trials included in the meta-analysis, participants receiving INCS were more likely to experience resolution or improvement in symptoms than those receiving placebo (73% versus 66.4%; risk ratio (RR) 1.11; 95% confidence interval (CI) 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement of symptoms or complete relief: for mometasone furoate 400 µg versus 200 µg (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and recurrence rates for the two treatment groups and for groups receiving higher doses of INCS.

AUTHORS' CONCLUSIONS

Current evidence is limited for acute sinusitis confirmed by radiology or nasal endoscopy but supports the use of INCS as a monotherapy or as an adjuvant therapy to antibiotics. Clinicians should weigh the modest but clinically important benefits against possible minor adverse events when prescribing therapy.

Clinical practice guideline for the diagnosis and management of acute bacterial sinusitis in children aged 1 to 18 years

OBJECTIVE

To update the American Academy of Pediatrics clinical practice guideline regarding the diagnosis and management of acute bacterial sinusitis in children and adolescents.

METHODS

Analysis of the medical literature published since the last version of the guideline (2001).

RESULTS

The diagnosis of acute bacterial sinusitis is made when a child with an acute upper respiratory tract infection (URI) presents with (1) persistent illness (nasal discharge [of any quality] or daytime cough or both lasting more than 10 days without improvement), (2) a worsening course (worsening or new onset of nasal discharge, daytime cough, or fever after initial improvement), or (3) severe onset (concurrent fever[temperature ≥39°C/102.2°F] and purulent nasal discharge for at least 3 consecutive days). Clinicians should not obtain imaging studies of any kind to distinguish acute bacterial sinusitis from viral URI, because they do not contribute to the diagnosis; however, a contrast-enhanced computed tomography scan of the paranasal sinuses should be obtained whenever a child is suspected of having orbital or central nervous system complications. The clinician should prescribe antibiotic therapy for acute bacterial sinusitis in children with severe onset or worsening course. The clinician should either prescribe antibiotic therapy or offer additional observation for 3 days to children with persistent illness. Amoxicillin with or without clavulanate is the firstline treatment of acute bacterial sinusitis. Clinicians should reassess initial management if there is either a caregiver report of worsening(progression of initial signs/symptoms or appearance of new signs/symptoms) or failure to improve within 72 hours of initial management.If the diagnosis of acute bacterial sinusitis is confirmed in a child with worsening symptoms or failure to improve, then clinicians may change the antibiotic therapy for the child initially managed with antibiotic or initiate antibiotic treatment of the child initially managed with observation.

CONCLUSIONS

Changes in this revision include the addition of a clinical presentation designated as “worsening course,” an option to treat immediately or observe children with persistent symptoms for 3 days before treating, and a review of evidence indicating that imaging is not necessary in children with uncomplicated acute bacterial sinusitis.

Evidence for the diagnosis and treatment of acute uncomplicated sinusitis in children: a systematic review

In 2001, the American Academy of Pediatrics published clinical practice guidelines for the management of acute bacterial sinusitis (ABS) in children. The technical report accompanying those guidelines included 21 studies that assessed the diagnosis and management of ABS in children. This update to that report incorporates studies of pediatric ABS that have been performed since 2001. Overall, 17 randomized controlled trials of the treatment of sinusitis in children were identified and analyzed. Four randomized, double-blind, placebo-controlled trials of antimicrobial therapy have been published. The results of these studies varied, likely due to differences in inclusion and exclusion criteria. Because of this heterogeneity, formal meta-analyses were not performed. However, qualitative analysis of these studies suggests that children with greater severity of illness at presentation are more likely to benefit from antimicrobial therapy. An additional 5 trials compared different antimicrobial therapies but did not include placebo groups. Six trials assessed a variety of ancillary treatments for ABS in children,and 3 focused on subacute sinusitis. Although the number of pediatric trials has increased since 2001, there are still limited data to guide the diagnosis and management of ABS in children. Diagnostic and treatment guidelines focusing on severity of illness at the time of presentation have the potential to identify those children most likely to benefit from antimicrobial therapy and at the same time minimize unnecessary use of antibiotics

Use of Topical or Systemic Steroids in Children with Upper Respiratory Tract Infection

Steroids have long been used to improve a number of clinical conditions because of their role in reducing inflammatory responses, but their use has always been limited because of their possible long-term side effects. The aim of this review is to establish whether steroids can have a positive effect on the outcome of some pediatric upper respiratory tract infections. We used PubMed to select all of the studies on topical or systemic steroids, and their therapeutic use in children with rhinosinusitis (RS), acute otitis media (AOM), otitis media with effusion (OME), acute pharyngitis (AP), or periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA), published over the last 15 years. Although a generally significant improvement in signs and symptoms has been observed with the use of intranasal steroids in children with RS, it is not clear which molecule should be recommended, how long treatment should be continued, or whether the benefits are limited to allergic children. No high-quality studies on the use of topical or systemic steroids in AOM have been carried out, and the results of studies of OME are controversial. The potential positive effects of steroids in children with AP are too slight to justify their use, and their possible adverse effects (particularly in the case of repeated administration) have not been clearly evaluated. Oral corticosteroids seem to be effective in resolving the symptoms of PFAPA, although they do not prevent future fever cycles. These findings show that further randomised and controlled studies are required in order to approach upper respiratory tract infections correctly and avoid the risks associated with frequent steroid use.

Short-course, low-dose oral betamethasone as an adjunct in the treatment of acute infective sinusitis : a comparative study with placebo

OBJECTIVE

To assess the effect of a short course of low-dose oral corticosteroid used as an adjunct to antimicrobials in patients with acute infective sinusitis.

STUDY DESIGN AND PATIENTS

Double-blind, randomised, placebo-controlled study including 42 patients with a clinical diagnosis of acute infective sinusitis. The study was performed at three primary healthcare sites in South Africa during the period January-November 2003.

INTERVENTION

Two equal groups received either betamethasone 1mg orally (n = 21; the treatment group) or placebo tablets (n = 21; the placebo group) once a day in the morning for five consecutive days. All patients received amoxicillin-clavulanic acid 625mg orally, three times daily for 5 days.

MAIN OUTCOME MEASURE

Patients rated symptoms on a daily symptom score card for 5 days and were examined by the investigator at diagnosis (day 0) and on the second visit (day 6).

RESULTS

Headache, facial pain, nasal congestion and dizziness improved significantly from baseline in the treatment group compared with the placebo group over 5 days of treatment (p = 0.028, p </= 0.047, p </= 0.04 and p </= 0.051, respectively). Percussion tenderness improved significantly (p = 0.049) and clearance of purulent secretions almost reached significance (p = 0.058) in the treatment group compared with the placebo group.

CONCLUSION

This study suggests a benefit of oral corticosteroid added to antimicrobial treatment of acute sinusitis and documents the first successful use of a short course of low-dose oral corticosteroid in patients with acute infective sinusitis.

Decongestants, antihistamines and nasal irrigation for acute sinusitis in children

BACKGROUND

The efficacy of decongestants, antihistamines and nasal irrigation in children with clinically diagnosed acute sinusitis has not been systematically evaluated.

OBJECTIVES

To systematically review the efficacy of decongestants, antihistamines and nasal irrigation in children with clinically diagnosed acute sinusitis. We considered the following four interventions: 1) decongestants versus placebo or no medication, 2) antihistamines versus placebo or no medication, 3) decongestant and antihistamine combination versus placebo or no medication, 4) nasal irrigation versus no irrigation. The primary outcomes of the review were symptom resolution (improvement in symptom score from enrolment to day five and overall symptom burden (as measured by average symptom scores while on therapy).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2012, Issue 1), which includes the Acute Respiratory Infections Group's Specialized Register, MEDLINE (1950 to January week 3, 2012) and EMBASE (1950 to January 2012).

SELECTION CRITERIA

We included randomized controlled trials (RCTs) and quasi-RCTs which evaluated children less than 18 years of age with acute sinusitis, defined as 10 to 30 days of rhinorrhea, congestion or daytime cough. We excluded trials of children with chronic sinusitis and allergic rhinitis.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed each study for inclusion.

MAIN RESULTS

Of the 526 studies found through the electronic searches and handsearching, none met all the inclusion criteria.

AUTHORS' CONCLUSIONS

There is no evidence to determine whether the use of antihistamines, decongestants or nasal irrigation is efficacious in children with acute sinusitis. Further research is needed to determine whether these interventions are beneficial in the treatment of children with acute sinusitis.

Treatment of congestion in upper respiratory diseases

Congestion, as a symptom of upper respiratory tract diseases including seasonal and perennial allergic rhinitis, acute and chronic rhinosinusitis, and nasal polyposis, is principally caused by mucosal inflammation. Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H₁-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines. Intranasal corticosteroids have broad anti-inflammatory activities, are the most potent long-term pharmacologic treatment of congestion associated with allergic rhinitis, and show some congestion relief in rhinosinusitis and nasal polyposis. Immunotherapy and surgery may be used in some cases refractory to pharmacotherapy. Steps in congestion management include (1) diagnosis of the cause(s), (2) patient education and monitoring, (3) avoidance of environmental triggers where possible, (4) pharmacotherapy, and (5) immunotherapy (for patients with allergic rhinitis) or surgery for patients whose condition is otherwise uncontrolled.

Clinicians should weigh the modest but clinically important benefits against possible minor adverse events when prescribing therapy.

Diagnosis and management of acute rhinosinusitis

Acute rhinosinusitis (ARS) is a highly prevalent condition with substantial public health implications. The disease is associated with a high degree of disability, impairment of quality of life, and school and workplace absenteeism. Acute rhinosinusitis is most often precipitated by a viral upper respiratory infection or an episode of allergic rhinitis. Typical signs and symptoms include nasal congestion, purulent nasal discharge, headache, cough, and facial pain or tenderness. Diagnosis is usually based on patient history and physical examination. Specialist consultation is indicated for intractable or complicated disease, signified by signs or symptoms suggestive of orbital, intraosseous, or intracranial extension of sinus disease. Most cases of ARS in the ambulatory setting are viral. In the absence of severe or rapidly worsening symptoms, antibiotic prescription should be delayed until an appropriate surveillance period has elapsed. Symptomatic therapy is the most efficient approach for uncomplicated ARS. There is a paucity of data supporting use of commonly used symptomatic therapies, with the exception of intranasal corticosteroids, which have demonstrated rapid improvement of the symptoms of ARS and return to normal functioning when used as monotherapy or as an adjunct to antibiotics.

Safety of intranasal corticosteroids in acute rhinosinusitis

Treatment guidelines for acute rhinosinusitis (RS) recommend the use of intranasal corticosteroids (INSs) as monotherapy or adjunctive therapy. However, the adverse event (AE) profiles of oral glucocorticoids, which result largely from the systemic absorption of those agents, have engendered concerns about the safety of INSs. These concerns persist for INSs despite significant or marked clinical differences between them and systemic corticosteroids in systemic absorption and among the INSs in bioavailability, mechanism of action, and lipophilicity, which may contribute to differences in AEs. For example, the systemic bioavailability of the INSs as a percentage of the administered drug is less than 0.1% for mometasone furoate, less than 1% for fluticasone propionate, 46% for triamcinolone acetonide, and 44% for beclomethasone dipropionate. A review of the safety profiles of INSs, as reported in clinical trials in acute and chronic RS and allergic rhinitis, shows primarily local AEs (eg, epistaxis and headache) that are generally classified as mild to moderate, with occurrence rates that are similar to those with placebo. Studies of the safety of mometasone furoate, fluticasone propionate, budesonide, and triamcinolone acetonide did not identify any evidence of systemic AEs, such as growth retardation in children due to suppression of the hypothalamic-pituitary-adrenal axis, bone mineral density loss, or cataracts, which suggests that INSs can be safely administered in patients with acute RS without concern for systemic AEs.

Intranasal corticosteroids in the treatment of acute rhinosinusitis

Acute rhinosinusitis (ARS) is one of the most frequent diagnoses in clinical practice. Common symptoms include anterior and/or posterior nasal drainage, nasal obstruction, and facial pain, pressure, or sensation of fullness. ARS etiology is more often viral than bacterial, and infection-initiated inflammation is the primary pathophysiologic mechanism responsible for symptoms. Because ARS is usually a self-limited process, the primary goal of treatment is symptom relief, which can be more effectively achieved by targeting the underlying inflammation. Intranasal steroids (INS) have been shown to reduce components of respiratory inflammation and increase symptom relief for ARS when used alone or combined with antibiotics. Based on current evidence in support of INS therapy, the European Position Paper on Rhinosinusitis and Nasal Polyps 2007 guidelines and a recent Cochrane meta-analysis recommend using INS in the treatment of ARS, both as monotherapy and as an adjunct to antibiotics.

Does post-nasal drip cause cough in childhood?

The proposition that post-nasal drip (PND) is a common cause of cough in childhood is controversial. The concept of PND as a common cause of cough is derived primarily from the adult literature. The definition of what constitutes PND is variable and it is unclear whether it is a symptom, a sign or both. Examination of the specificity of symptoms and signs for the diagnosis of PND syndrome further confuses the issue. A definitive diagnosis of cough induced by PND cannot be made from history and physical examination alone. The concept is inconsistent both with the meaning of the word 'drip' and the science of rheology. The most plausible explanation for the occurrence of cough in children identified with increased post-nasal secretions is that both reflect co-existent airways pathologies. In considering causes of chronic cough in childhood, it is now time to abandon the concept of PND and the associated PND syndrome.

Guidelines for evaluating chronic cough in pediatrics: ACCP evidence-based clinical practice guidelines

OBJECTIVES

To review relevant literature and present evidence-based guidelines to assist general and specialist medical practitioners in the evaluation and management of children who present with chronic cough.

METHODOLOGY

The Cochrane, MEDLINE, and EMBASE databases, review articles, and reference lists of relevant articles were searched and reviewed by a single author. The date of the last comprehensive search was December 5, 2003, and that of the Cochrane database was November 7, 2004. The authors' own databases and expertise identified additional articles.

RESULTS/CONCLUSIONS

Pediatric chronic cough (ie, cough in children aged <15 years) is defined as a daily cough lasting for >4 weeks. This time frame was chosen based on the natural history of URTIs in children and differs from the definition of chronic cough in adults. In this guideline, only chronic cough will be discussed. Chronic cough is subdivided into specific cough (ie, cough associated with other symptoms and signs suggestive of an associated or underlying problem) and nonspecific cough (ie, dry cough in the absence of an identifiable respiratory disease of known etiology). The majority of this section focuses on nonspecific cough, as specific cough encompasses the entire spectrum of pediatric pulmonology. A review of the literature revealed few randomized controlled trials for treatment of nonspecific cough. Management guidelines are summarized in two pathways. Recommendations are derived from a systematic review of the literature and were integrated with expert opinion. They are a general guideline only, do not substitute for sound clinical judgment, and are not intended to be used as a protocol for the management of all children with a coughing illness. Children (aged <15 years) with cough should be managed according to child-specific guidelines, which differ from those for adults as the etiologic factors and treatments for children are sometimes different from those for adults. Cough in children should be treated based on etiology, and there is no evidence for using medications for the symptomatic relief of cough. If medications are used, it is imperative that the children are followed up and therapy with the medications stopped if there is no effect on the cough within an expected time frame. An evaluation of the time to response is important. Irrespective of diagnosis, environmental influences and parental expectations should be discussed and managed accordingly. Cough often impacts the quality of life of both children and parents, and the exploration of parental expectations and fears is often valuable in the management of cough in children.

Treatment options for acute sinusitis in children

Much controversy exists regarding the best diagnostic method for acute sinusitis, the efficacy of antibiotics, the best choice of antibiotics, the most appropriate duration of therapy, and the efficacy of ancillary measures and nasal corticosteroids. The therapeutic goal is to identify those children who are more likely to have bacterial sinusitis and unlikely to resolve spontaneously, who may require treatment with antibiotics. The inaccuracy of clinical signs and symptoms complicates further the management of these children. Acute sinusitis is expected to resolve spontaneously in most cases, including many cases of bacterial sinusitis. Antibiotics are needed only for a minority of non-self-resolving infections. Based on current resistance considerations, approximately 80% of bacterial infections are expected to respond to standard doses of amoxicillin. High-dose amoxicillin, amoxicillin/clavulanate, or other b-lactam antibiotics should be considered for children at high risk for carrying resistant organisms.

Acute sinusitis in children: current treatment strategies

Acute sinusitis is a very common infection in childhood, but its management remains a controversial issue. Antibacterials may be effective in selected children, but direct evidence is limited. One randomized, placebo-controlled trial has shown that amoxicillin or amoxicillin/clavulanate are better than placebo for children with symptoms of nasal discharge and cough that are persistent (over 10 days) and not improving. However, another placebo-controlled trial of the same agents did not demonstrate any benefit from antibacterials in a patient population selected with a clinical diagnosis of sinusitis of moderate severity, based on a composite clinical symptom score. A systematic assessment of cure rates with various antibacterials shows no consistent differences between classes. Evidence on the use of ancillary measures and nasal corticosteroids is also limited. The only randomized, placebo-controlled trial of antihistamines and decongestants has shown no incremental benefit when given in addition to amoxicillin. Another placebo-controlled randomized trial showed some transient symptomatic improvement with the use of nasal corticosteroids. No randomized trials exist on the use of antral lavage in children with acute sinusitis. The current rates of antimicrobial resistance among commonly implicated pathogens should be considered in therapeutic decisions. However, there is no evidence from well-designed trials on specifically how to manage children at high risk of carrying resistant organisms. The inaccuracy of clinical signs and symptoms in documenting the diagnosis further complicates therapeutic decisions. Nevertheless, radiographic assessment does not meaningfully improve the accuracy of the diagnosis for uncomplicated cases, and it is not cost effective. In the absence of definitive evidence, treatment with amoxicillin 45 mg/kg/day in two divided doses may be used in selected patients with symptoms that are persistent and not improving. High doses (90 mg/kg in two divided doses) may also be considered, and amoxicillin/clavulanate may be a more appropriate choice when there is high risk of resistant pathogens, e.g. in a child attending a childcare center, or recent use of antibacterials. However, a considerable proportion of children, especially those with mild or improving symptoms, may not have to be treated at all.
