Acute pharyngitis in children and adults: descriptive comparison of current recommendations from national and international guidelines and future perspectives. Eur J Pediatr 2023; 182:5259-5273. [PMID: 37819417 PMCID: PMC10746578 DOI: 10.1007/s00431-023-05211-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 09/12/2023] [Accepted: 09/15/2023] [Indexed: 10/13/2023]
Abstract
This study aims to provide a comparison of the current recommendations about the management of acute pharyngitis. A literature search was conducted from January 2009 to 2023. Documents reporting recommendations on the management of acute pharyngitis were included, pertinent data were extracted, and a descriptive comparison of the different recommendations was performed. The quality of guidelines was assessed through the AGREE II instrument. Nineteen guidelines were included, and an overall moderate quality was found. Three groups can be distinguished: one group supports the antibiotic treatment of group A β-hemolytic Streptococcus (GABHS) to prevent acute rheumatic fever (ARF); the second considers acute pharyngitis a self-resolving disease, recommending antibiotics only in selected cases; the third group recognizes a different strategy according to the ARF risk in each patient. An antibiotic course of 10 days is recommended if the prevention of ARF is the primary goal; conversely, some guidelines suggest a course of 5-7 days, assuming the symptomatic cure is the goal of treatment. Penicillin V and amoxicillin are the first-line options. In the case of penicillin allergy, first-generation cephalosporins are a suitable choice. In the case of beta-lactam allergy, clindamycin or macrolides could be considered according to local resistance rates. Conclusion: Several divergencies in the management of acute pharyngitis were raised among guidelines (GLs) from different countries, both in the diagnostic and therapeutic approach, allowing the distinction of 3 different strategies. Since GABHS pharyngitis could affect the global burden of GABHS disease, it is advisable to define a shared strategy worldwide. It could be interesting to investigate the following issues further: cost-effectiveness analysis of diagnostic strategies in different healthcare systems; local genomic epidemiology of GABHS infection and its complications; the impact of antibiotic treatment of GABHS pharyngitis on its complications and invasive GABHS infections; the role of GABHS vaccines as a prophylactic measure. The related results could aid the development of future recommendations. What is Known: • GABHS disease spectrum ranges from superficial to invasive infections and toxin-mediated diseases. • GABHS accounts for about 25% of sore throat in children and its management is a matter of debate. What is New: • Three strategies can be distinguished among current GLs: antibiotic therapy to prevent ARF, antibiotics only in complicated cases, and a tailored strategy according to the individual ARF risk. • The impact of antibiotic treatment of GABHS pharyngitis on its sequelae still is the main point of divergence; further studies are needed to achieve a global shared strategy.

Pharmacological effects and mechanism of Kaihoujian Throat Spray (children's type) in the treatment of pediatric acute pharyngitis and tonsillitis. Heliyon 2023; 9:e17802. [PMID: 37539230 PMCID: PMC10395134 DOI: 10.1016/j.heliyon.2023.e17802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 06/16/2023] [Accepted: 06/28/2023] [Indexed: 08/05/2023] Open
Abstract
Context Kaihoujian Throat Spray children's type (KHJSC) is a Chinese medicine prescription for treating pediatric acute pharyngitis and tonsillitis (APT). However, its relevant mechanisms remain unclear. Objective To investigate the pharmacological effects of KHJSC on APT in vitro and in vivo, and explore the possible mechanism and target proteins. Materials and methods The antiviral and antibacterial effects in vitro were evaluated by IC50 and MICs. Thirty-six Japanese white rabbits were averagely divided into control group, model group, amoxicillin group and 3 dose groups of KHJSC (720, 540 and 360 μL/kg/d). The model rabbits were injected with β-hemolytic Streptococcus solution into the tonsils for 2 consecutive days. KHJSC treatment started on the third day. The whole blood, serum, tonsil tissues and pharyngeal mucosa tissues were collected for routine blood tests, proteomic, ELISA and other tests on the sixth day. Results The IC50 of KHJSC on HCoV-229E, influenza PR8 and Ad3 were 1.99, 1.99 and 4.49 mg/mL, respectively; MICs of MDR-PA, MRSA and β-hemolytic Streptococcus were 350, 350, and 175 mg/mL. KHJSC markedly decreased the number of white blood cells, lymphocytes, neutrophils, and the level of IL-1β, IL-5, IL-6, IL-18, TNF-α and MCP-1; increased the content of IL-2 and IFN-γ. Proteomic analysis and ELISA revealed that PI3K-Akt signaling pathway, NF-κB signaling pathway and Toll-like receptor signaling pathway were the potential mechanisms of KHJSC against APT. Discussion and conclusion These results provided the reference and scientific basis for the application of KHJSC in clinic and further mechanisms study.

Abstract
Overuse and misuse of antibiotics have strongly accelerated the progressive increase in bacterial antimicrobial resistance (AMR). The evidence that antimicrobial selective pressure was greater the longer the antibiotic therapy was continued has led some experts to reconsider duration of antibiotic therapy testing the use of short-term drug administration. If as effective as long-term therapy, short-term therapy could have been an easy measure to limit AMR emergence. In the present narrative review, whether present knowledge on short-term therapy of acute streptococcal pharyngitis (ASF), acute otitis media (AOM) and mild to moderate community-acquired pneumonia (CAP) allows systematic use of short-term therapy in infants and children with these diseases is discussed. Literature analysis showed that reducing the duration of antibiotic therapy for some of the most common pediatric respiratory infections could be a valid measure to contain the antibiotic abuse and the consequent impact on the emergence of AMR. Several data seem to indicate that this type of intervention is possible, as short-term therapy has been found as effective as the traditionally recommended long-term therapy in some cases of ASF, AOM and mild to moderate CAP. However, further studies are needed to better characterize infants and children who can have benefit with short-term antibiotic therapy in common bacterial respiratory infections.

Abstract
Introduction. Using rapid antigen diagnostic tests (RADTs) in clinical practice has shown excellent specificity but often has diminished sensitivity.Gap Statement. Local data for evaluating the diagnostic performance of a new fluorescence-based RADT and its influence on the antibiotic prescription rate are not available.Aim. To evaluate the accuracy of fluorescent immunoassay (FIA)-RADTs for diagnosing group A streptococcal (GAS) pharyngitis among children and its estimated effect as a point of care test (POCT) on the antibiotic prescription rate at the paediatric emergency department.Methodology. A prospective study was conducted, comprising children 3 to 14 years old presenting with pharyngitis. Throat swab culture and FIA-RADTs were performed on all samples. Conventional PCR was performed on the discordant samples.Results. A total of 246 children were included in this study. The sensitivity, specificity, and positive and negative predictive values of the FIA-RADT, based on culture results and PCR detection combined, were 95.6, 96.8, 94.6 and 97.4 %, respectively. Antibiotics have been prescribed to 162 (65.9 %) children; however, if FIA-RADTs had been added in the clinical practice as a POCT, only 92 (37.4 %) children would have received antibiotics in total. Additionally, implementation of FIA-RADTs would significantly reduce the antibiotic prescription rate from 48.8 and 60.6 % to 9.5 and 31.9 % among patients with clinical scores of 2 and 3, respectively.Conclusion. The new FIA-RADT is simple, prompt and reliable. It is helpful in clinical settings and may be used to reduce antibiotic overprescription, especially for children who have a low risk for GAS pharyngitis, according to the clinical score.

Abstract
Background Tonsillopharyngitis is one of the most frequently observed upper respiratory tract infections, for which antibiotics are prescribed in ambulatory care. In most cases, tonsillopharyngitis is benign and self-limiting, mostly a viral condition. The aim of this study was to explore the diagnostic and treatment process of tonsillopharyngitis by general practitioners and to understand decisions regarding antibiotic prescribing and the factors that shape these practices. Methods/design This was a qualitative interview study in primary care practices in Latvia. Semi-structured face-to-face interviews were conducted with general practitioners from November 2016 to January 2017. Thematic analysis was applied to identify factors that influence the prescribing practice in a primary care setting in conjunction with a specific context in which the prescriber practices. Results Decisions and practice of general practitioner are not static over time or context; they occur within an environmental setting influenced by individual factors of general practitioners, the health care system, and practice-specific factors that shape the diagnosis and antibiotic prescribing in the tonsillopharyngitis. Interviewed general practitioners rely primarily on their personal experience, perception, and skills acquired in their practice, which are encouraged by the environment, where the necessary tools and resources are not in place to encourage rational prescribing of antibiotics. Conclusions General practitioners’ decision regarding antibiotic prescribing is an unstable concept that differs between prescribers. The health care system could augment the experience of general practitioners through structural changes such as guidelines, availability of antibiotics, and available antibiotics package size.

Abstract
Acute respiratory infections are the most common group of infective diseases in the pediatric population. Although the improvement of health care and vaccination program has led to a significant reduction in the incidence of certain respiratory infections, the combination of a high prevalence in vulnerable pediatric categories and uncritical prescription of antibiotics, due to the inability to adequately distinguish between viruses and bacterial etiology, still represents a significant challenge for the public health system. In order to promote rational antibiotic therapy with an overall improvement of both diagnostic and therapeutic principles, acute respiratory diseases have been the subject of consideration in numerous publications and national guidelines. Nonspecific clinical manifestations with pathogen heterogeneity and both anatomical and physiological characteristics of the child's respiratory system during growth and development have created the need for individualized therapy. Since the guidelines emphasize the undoubtful and crucial benefits of symptomatic therapy (e.g. analgesics in acute otitis media, supplemental oxygen in lower respiratory tract infections with hypoxemia), the use of antibiotics and corticosteroids is indicated in selected cases with a severe clinical picture. The choice of antibiotic depends on the clinical condition, presumed causative agent, and local epidemiologic circumstances. Respiratory support (oxygen therapy and/or artificial ventilation) is reserved for inpatient treatment of cases with a particularly severe clinical picture and associated complications.

Abstract
Acute pharyngitis is an inflammation of the pharyngeal mucous membrane and submucous lymphoid tissues. Unsatisfactory treatment and repeated occurrences might cause chronic pharyngitis and other complications. Syringa oblata L. (S. oblata) is a traditional Chinese medicine that exhibited a significant therapeutic effect on various inflammatory diseases. Its commercial drug Yan Li Xiao (YLX) capsule is used as a cure for the treatment of inflammatory diseases, such as bacillary dysentery, tonsillitis, bronchitis, and acute gastroenteritis. However, studies about S. oblata relieving acute pharyngitis are rare. In this study, high-performance liquid chromatography (HPLC) was used to analyze the chemical profile of S. oblata, and the bioactive phytoconstituents were isolated and identified by nuclear magnetic resonance (NMR) and mass spectrometry. An ammonia-induced acute pharyngitis rat model was established to estimate the protective effect of S. oblata in vivo for the first time. The severity of pharyngitis was observed by appearance index and HE staining. The cytokines expression was performed by ELISA. Crucial proteins expression associated with TLR4/NF-κB/MAPK and NLRP3 inflammasome signaling pathways were analyzed by western blotting and immunohistochemistry. Furthermore, the anti-inflammatory effect of isolated compounds was evaluated by suppressing lipopolysaccharide- (LPS-) induced NO generation and regulating the cytokines levels in RAW 264.7 cells. The results showed that S. oblata exhibited a protective effect in the ammonia-induced acute pharyngitis rat model, and the compounds exert potential anti-inflammatory properties against LPS-activated RAW 254.7 cells.

Abstract
BACKGROUND Acute pharyngitis is one of the most common conditions in outpatient settings and an important source of inappropriate antibiotic prescribing. Rapid antigen detection tests (RADTs) offer diagnosis of group A streptococcus at the point of care but have limited sensitivity. Rapid nucleic acid tests (RNATs) are now available; a systematic review of their accuracy is lacking. OBJECTIVES To evaluate the accuracy of RNATs in patients with pharyngitis; to explore test-level and study-level factors that could explain variability in accuracy; and to compare the accuracy of RNATs with that of RADTs. DATA SOURCES MEDLINE, Embase, Web of Science (1990-2020). STUDY ELIGIBILITY CRITERIA Cross-sectional studies and randomized trials. PARTICIPANTS Patients with pharyngitis. INDEX TEST/S AND REFERENCE STANDARDS RNAT commercial kits compared with throat culture. METHODS We assessed risk of bias and applicability using QUADAS-2. We performed meta-analysis of sensitivity and specificity using the bivariate random-effects model. Variability was explored by subgroup analyses and meta-regression. RESULTS We included 38 studies (46 test evaluations; 17 411 test results). RNATs were most often performed in a laboratory. The overall methodological quality of primary studies was uncertain because of incomplete reporting. RNATs had a summary sensitivity of 97.5% (95% CI 96.2%-98.3%) and a summary specificity of 95.1% (95% CI 93.6%-96.3%). There was low variability in estimates across studies. Variability in sensitivity and specificity was partially explained by test type (p < 0.05 for both). Sensitivity analyses limited to studies with low risk of bias showed robust accuracy estimates. RNATs were more sensitive than RADTs (13 studies; 96.8% versus 82.3%, p 0.004); there was no difference in specificity (p 0.92). CONCLUSIONS The high diagnostic accuracy of RNATs may allow their use as stand-alone tests to diagnose group A streptococcus pharyngitis. Based on direct comparisons, RNATs have greater sensitivity than RADTs and equal specificity. Further studies should evaluate RNATs in point-of-care settings.

Abstract
Introduction Sore throat (acute pharyngitis) is globally one of the most frequent reasons for seeking healthcare. Its etiology is mostly viral. In 15%‐30% of cases, group A streptococci (GAS) are detected, which may cause acute rheumatic fever. We have done a worldwide systematic review to compare diagnostic and therapeutic guidelines across countries and regions. Previous reviews of sore throat guidelines were limited to specific regions and/or language; this is the first global review. Materials and Methods Searches were performed in MEDLINE, EMBASE and COCHRANE (key words: sore throat, pharyngitis, tonsillitis or pharyngotonsillitis, and management, guidance, guideline or recommendation) and on the web sites of major health authorities and associated institutions from Africa, Asia, Europe, Middle East, North America, Oceania and South America. Results Thirty‐six guidelines were identified from 26 countries. Most common are recommendations relying on the symptom‐ and age‐based Centor or McIsaac scores. However, antibiotic treatment may be based on other symptomatic criteria; in the most extreme approach just sore throat in children. The recommendation of GAS‐specific diagnostic tests is mainly limited to countries where such tests are readily available, although some countries choose not to use them. Penicillins are consistently recommended as first‐line antibiotics. By contrast, guidance for symptomatic treatment is variable and mostly sparse or missing. African countries without sore throat guidelines and Asian countries bypassing them are afflicted by rising antibiotic resistance. Conclusion The availability of sore throat guidelines varies considerably by region and country. Moreover, important divergence is found among the guidelines regarding diagnostic and treatment criteria. This may be explained by the historical background or adoption of external guidelines, rather than local incidences of GAS infections or acute rheumatic fever. Absence of recommendations on symptomatic treatment in many guidelines is concerning, and raises issues about antimicrobial stewardship, as this should be the mainstay of sore throat management, rather than antibiotics.

Abstract
BACKGROUND Pharyngitis due to group A Streptococcus (GAS) represents a major cause of outpatient visits and antibiotic use in the United States. A leading vaccine candidate targets 30 of the > 200 emm types of GAS. We aimed to assess natural protection conferred by GAS against respiratory symptoms. METHODS In a 5-year study among school-aged children in Pittsburgh, Pennsylvania, pharyngeal cultures were obtained from children at 2-week intervals, and active surveillance was conducted for respiratory illnesses. We assessed protection via the relative odds of previous detection of homologous strains (defined by field-inversion gel electrophoresis banding pattern), emm types, and emm clusters at visits where GAS was detected with symptoms, vs visits where GAS was detected without symptoms. We used a cluster bootstrap of children to adjust estimates for repeated sampling. RESULTS At visits where previously detected GAS emm types were identified, we estimated 81.8% (95% confidence interval [CI], 67.1%-91.7%) protection against typical pharyngitis symptoms among children reacquiring the same strain, and 94.5% (95% CI, 83.5%-98.6%) protection among children acquiring a distinct strain. We estimated 77.1% (95% CI, 33.7%-96.3%) protection against typical symptoms among children acquiring partially heterologous emm types belonging to a previously detected emm cluster. Protection was evident after both symptomatic and asymptomatic detections of GAS. We did not identify strong evidence of protection against atypical respiratory symptoms. CONCLUSIONS Within a 5-year longitudinal study, previous detection of GAS emm types was associated with protection against typical symptoms when homologous strains were subsequently detected. Naturally acquired protection against partially heterologous types suggests that emm type-based vaccines may have broader strain coverage than what has been previously assumed.

Abstract
Abstract
Objective Acute tonsillopharyngitis (ATP) is a common, seasonal infection of predominantly viral origin. Management is aimed at shortening the course of the disease and restoring the comfort of the patient. We performed a meta-analysis to investigate whether treatment with the Pelargonium sidoides extract EPs 7630 reduces the use of antipyretic comedication (i.e., acetaminophen) in children suffering from ATP.
Methods Studies were identified from clinical trial registries and medical literature. Randomized, placebo-controlled, clinical trials investigating EPs 7630 in children with ATP and reporting the coadministration of paracetamol were eligible. Based on the raw data of eligible trials, we analyzed cumulative paracetamol use, as well as the ability to attend school at the end of treatment. Three trials including a total of 345 children aged 6 to 10 years and suffering from non-β-hemolytic streptococcal ATP were identified and eligible. Children were administered EPs 7630 or placebo for 6 days.
Results Compared with placebo, EPs 7630 reduced the cumulative paracetamol dose by an average of 449 mg (95% confidence interval [CI]: 252–646 mg; p < 0.001). A total of 19.1% (EPs 7630) and 71.5% (placebo) of children were still unable to attend school at the end of the treatment (risk ratio = 0.28; 95% CI: 0.16–0.48; p < 0.001).
Conclusion Our meta-analysis demonstrates that EPs 7630 reduced the use of antipyretic comedication and accelerated recovery.

Abstract
Background Antibiotics are among the most frequently administered drugs globally, yet they are often prescribed inappropriately. Guidelines for prescribing are developed by expert committees at international and national levels to form regional standards and by local experts to form hospital guidance documents. Our aim was to assess variability in antibiotic prescription guidelines for both regional standards and individual hospitals. Methods A search through 3 publicly accessible databases from February to June 2018 led to a corpus of English language guidance documents from 70 hospitals in 12 countries and regional standards from 7 academic societies. Results Guidelines varied markedly in content and structure, reflecting a paucity of rules governing their format. We compared recommendations for 3 common bacterial infections: community-acquired pneumonia, urinary tract infection, and cellulitis. Hospital guidance documents and regional standards frequently disagreed on preferable antibiotic classes for common infections. Where agreement was observed, guidance documents appeared to inherit recommendations from their respective regional standards. Several regional prescribing patterns were identified, including a greater reliance on penicillins over cephalosporins in the United Kingdom and fluoroquinolones in the United States. Regional prescribing patterns could not be explained by antibiotic resistance or costs. Additionally, literature that cited underlying recommendations did not support the magnitude of recommendation differences observed. Conclusions The observed discordance among prescription recommendations highlights a lack of evidence for superior treatments, likely resulting from a preponderance of noninferiority trials comparing antibiotics. In response, we make several suggestions for developing guidelines that support best practices of antibiotic stewardship.

Abstract
The purpose of the study. To establish the effectiveness of symptom reduction and preventive action of the herbal drug Tonsilgon N (HD) as monotherapy for exacerbations of chronic tonsillitis/pharyngitis in adult patients. MATERIAL AND METHODS The study included 60 adult male and female patients aged 18 to 60 years with an established diagnosis of acute tonsillopharyngitis. In total, each patient underwent 5 visits. Visit 1 - enrollment in the study and beginning of HD monotherapy, Visit 2 - on Day 7, Visit 3 - on Day 14 and completion of HD monotherapy, Visit 4 - on Day 60 and Visit 5 - on Day 180. The diagnosis of the disease and the examination of the patient was carried out on the basis of anamnesis, general clinical and ENT examination, palpation of regional lymph nodes. The severity of the clinical signs was evaluated on the basis of the symptom score. The general condition of the patient was also evaluated using a visual analogue scale (VAS) and the number of exacerbations of tonsillopharyngitis during the observation period. RESULTS The number of exacerbations of chronic tonsillitis and episodes of ATP for 6 months after the end of treatment decreased 4.8 times compared to the previous period. During the course of treatment (14 days), complaints of patients with ATP (general health and/or fatigue, pain when swallowing, headache, cough, burning sensation, a lump in the throat, hoarseness, pain and dryness in the throat, difficulty swallowing) had a pronounced tendency to regression. Improvement was also noted on examination and clinical evaluation. According to the results of the analysis of the evaluation of general condition according to the VAS (according to the standard technique in cm), there was a significant improvement both during the treatment period by 2.2 times, and during the observation period (180 days) from the period of Visit 2 to Visit 4 by 31.3 times. CONCLUSION The use of HD as monotherapy for non-streptococcal ATP has shown its high efficiency. The possibility of using Tonsilgon N was shown as a prophylactic agent that reduces the number of exacerbations of inflammatory diseases in the pharynx during the period after the treatment course.

Abstract
The most common bacterial cause of pharyngitis is infection by Group A β-hemolytic streptococcus (GABHS), commonly known as strep throat. 5-15% of adults and 15-35% of children in the United States with pharyngitis have a GABHS infection. The symptoms of GABHS overlap with non-GABHS and viral causes of acute pharyngitis, complicating the problem of diagnosis. A careful physical examination and patient history is the starting point for diagnosing GABHS. After a physical examination and patient history is completed, five types of diagnostic methods can be used to ascertain the presence of a GABHS infection: clinical scoring systems, rapid antigen detection tests, throat culture, nucleic acid amplification tests, and machine learning and artificial intelligence. Clinical guidelines developed by professional associations can help medical professionals choose among available techniques to diagnose strep throat. However, guidelines for diagnosing GABHS created by the American and European professional associations vary significantly, and there is substantial evidence that most physicians do not follow any published guidelines. Treatment for GABHS using analgesics, antipyretics, and antibiotics seeks to provide symptom relief, shorten the duration of illness, prevent nonsuppurative and suppurative complications, and decrease the risk of contagion, while minimizing the unnecessary use of antibiotics. There is broad agreement that antibiotics with narrow spectrums of activity are appropriate for treating strep throat. But whether and when patients should be treated with antibiotics for GABHS remains a controversial question. There is no clearly superior management strategy for strep throat, as significant controversy exists regarding the best methods to diagnose GABHS and under what conditions antibiotics should be prescribed.

Abstract
Background Acute sore throat is one of the most common problems for which patients consult their general practitioner and is a key area for inappropriate antibiotic prescribing. The objective of this study was to investigate patients’ attitudes related to healthcare-seeking behavior and self-management of sore throat. Methods We conducted an observational, questionnaire-based study across 13 countries (Australia, Brazil, China, France, Germany, Italy, the Philippines, Russia, Saudi Arabia, South Africa, Thailand, the UK and the USA) on respondents who reported having had a sore throat in the previous 12 months. Data were collected on their experiences, contact with healthcare professionals, treatment practices and opinions about antibiotics. Results A total of 5196 respondents (approximately 400 per country) completed the survey. Over 80% of respondents sought advice for a sore throat, with 30% consulting a general practitioner. The desire to limit the worsening of symptoms was the main reason for seeking treatment. Other reasons concerned resolving persistent symptoms and reducing the impact on daily life/sleep. Self-management for sore throat was mainly medicated sore throat remedies. “Wanting an antibiotic” was rated much lower (55%) than most other reasons for visiting a doctor, but this differed greatly between countries. The percentage of respondents using antibiotics varied widely, for example, 10% in the UK and 45% in Saudi Arabia. There was considerable variation in the proportion of respondents who thought that antibiotics would be effective against sore throat (from 24% in France to 94% in Saudi Arabia). Conclusions Our findings suggest that knowledge of effective treatments for sore throat varied widely. The results of this study should enable healthcare professionals to better anticipate patients’ needs. This will support healthcare professionals in their role as antibiotic stewards, helping to reduce the misuse of antibiotics, and further guiding patients towards symptomatic self-management of sore throat.

Abstract
BACKGROUND Chronic pharyngitis is a common disease with a dry throat, sore throat, pharyngeal itching, dry cough, and difficulty in swallowing, bringing inconvenience to patients' daily life. Banxia-Houpo-Tang (BHT) has proven to be effective in the treatment of chronic pharyngitis, yet its real extent is not well understood. To prove this point, we will perform a protocol for a systematic review and meta-analysis of BHT for chronic pharyngitis. METHODS/DESIGN We will search for electronic databases both English and Chinese from inception to December 2019. Two experienced researchers select the qualified articles from: The Cochrane Library, EBM Reviews, OVID, Web of Science, PubMed, Chinese National Knowledge Infrastructure (CNKI), China Academic Journal Network Publishing Database (CAJD), China Biomedical Literature database (CBM), VIP Database for Chinese Technical Periodicals (VIP). Journal Integration Platform and WAN FANG Database. We select the appropriate searching language. The primary outcome was remission rate, and the secondary outcomes include clinical symptoms, clinical examination, adverse event. Data extraction and quality assessment will be conducted by 2 experienced researchers independently. Data analysis and the risk of bias assessment will be determined by RevMan 5.3 software. RESULTS Based on the current proofs, we will get the exact evidence about the safety and effectiveness of BHT in the treatment of chronic pharyngitis. CONCLUSION Our study is the first meta-analysis to evaluate the efficacy and safety of BHT in the treatment of chronic pharyngitis, and it will provide evidence for alternative treatment for the management of chronic pharyngitis.

Abstract
OBJECTIVES Unnecessary use of antibiotics is one of the causes of antibiotic resistance. Rapid Antigen Test (RAT) is recommended to prevent unnecessary use of antibiotics by providing bacteria/virus isolation in patients with tonsillopharyngitis. However, in patients with typical symptoms, false-negative test results may lead to doubt in doctors. In this study, we aimed to evaluate the relationship between patients' symptoms and RAT results. METHODS In this study, we chose the patients that referred to the University of Health Sciences (SBÜ) Şişli Hamidiye Etfal Training and Research Hospital Family Medicine Polyclinics and got a diagnosis of tonsillopharyngitis with RAT. This study was conducted by a retrospective file scanning method. We examined the age, sex, symptoms, RAT results and throat culture results of the patients. SPSS 15.0 for Windows program was used for the statistical analysis. The level of statistical significance was accepted as p<0.05. RESULTS In this study, the RAT of 265 patients and the throat culture of 141 patients were examined. We found RAT positivity as 28.7%, Group A Beta Hemolytic Streptococcus (AGBHS) detection rate in throat culture was 22.5%, and the antibiotic prescription rate was 37%. There were 32 patients with AGBHS positivity in throat culture. Twenty-seven of them got RAT positivity, too. When symptoms and RAT positivity were examined, there was no significant relationship between RAT positivity and fever higher than 38 oC, but RAT was more often positive in patients with a fever higher than 38 oC. On the other hand, there is a statistically significant relationship between RAT positivity and the presence of tonsillar exudate (p=0.000). When the relationship between symptoms and RAT according to age groups was examined, the presence of LAP and tonsillitis were significant (p=0.000; p=0.001). In the age group of 18 years and over, the presence of tonsillar exudates was significant (p=0.001). CONCLUSION In our study, tonsillar exudate was a common symptom in both age groups of <18, and ≥18 years of age; at the same time, there is a statistically significant relation with RAT. Tonsillar exudates are not seen only in bacterial infections but also in viral infections. Thus, we think that antibiotics should not be started based on symptoms, and RAT should be used effectively.

Abstract
Background Centor and McIsaac scores are both used to diagnose group A beta-haemolytic streptococcus (GABHS) infection, but have not been compared through meta-analysis. Aim To compare the performance of Centor and McIsaac scores at diagnosing patients with GABHS presenting to primary care with pharyngitis. Design and setting A meta-analysis of diagnostic test accuracy studies conducted in primary care was performed using a novel model that incorporates data at multiple thresholds. Method MEDLINE, EMBASE, and PsycINFO were searched for studies published between January 1980 and February 2019. Included studies were: cross-sectional; recruited patients with sore throats from primary care; used the Centor or McIsaac score; had GABHS infection as the target diagnosis; used throat swab culture as the reference standard; and reported 2 × 2 tables across multiple thresholds. Selection and data extraction were conducted by two independent reviewers. QUADAS-2 was used to assess study quality. Summary receiver operating characteristic (SROC) curves were synthesised. Calibration curves were used to assess the transferability of results into practice. Results Ten studies using the Centor score and eight using the McIsaac score were included. The prevalence of GABHS ranged between 4% and 44%. The areas under the SROC curves for McIsaac and Centor scores were 0.7052 and 0.6888, respectively. The P-value for the difference (0.0164) was 0.419, suggesting the SROC curves for the tests are equivalent. Both scores demonstrated poor calibration. Conclusion Both Centor and McIsaac scores provide only fair discrimination of those with and without GABHS, and appear broadly equivalent in performance. The poor calibration for a positive test result suggests other point-of-care tests are required to rule in GABHS; however, with both Centor and McIsaac scores, a score of ≤0 may be sufficient to rule out infection.

Abstract
Pharyngitis is usually caused by a viral infection for which antibiotics are often unnecessarily prescribed, adding to the burden of antimicrobial resistance. Identifying who needs antibiotics is challenging; microbiological confirmation and clinical scores are used but have limitations. In a cross-sectional study nested within a randomized controlled trial, we estimated the prevalence and antibiotic susceptibility profiles of group A Streptococcus (GAS) in patients presenting to primary care with a sore throat and fever in northern Thailand. We then evaluated the use of C-reactive protein (CRP) and clinical scores (Centor and FeverPAIN) to identify the presence of GAS. One hundred sixty-nine patients were enrolled, of whom 35 (20.7%) had β-hemolytic Streptococci (BHS) isolated from throat swab culture, and 11 (6.5%) had GAS. All GAS isolates were sensitive to penicillin G. The median CRP of those without BHS isolation was 10 mg/L (interquartile range [IQR] ≤ 8-18), compared with 18 mg/L (IQR 9-71, P = 0.0302) for those with GAS and 14 mg/L (IQR ≤ 8-38, P = 0.0516) for those with any BHS isolated. However, there were no significant relationships between CRP > 8 mg/L (P = 0.112), Centor ≥ 3 (P = 0.212), and FeverPAIN ≥ 4 (P = 1.000), and the diagnosis of GAS compared with no BHS isolation. Identifying who requires antibiotics for pharyngitis remains challenging and necessitates further larger studies. C-reactive protein testing alone, although imperfect, can reduce prescribing compared with routine care. Targeted CRP testing through clinical scoring may be the most cost-effective approach to ruling out GAS infection.

Hoban DJ, Nauta J. Clinical And Bacteriological Impact Of Clarithromycin In Streptococcal Pharyngitis: Findings From A Meta-Analysis Of Clinical Trials. DRUG DESIGN DEVELOPMENT AND THERAPY 2019; 13:3551-3558. [PMID: 31802844 PMCID: PMC6801486 DOI: 10.2147/dddt.s205820] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2019] [Accepted: 09/11/2019] [Indexed: 11/30/2022]
Abstract
Introduction Among the bacterial upper respiratory tract infections (UTRIs), the most medically significant is pharyngitis due to Group A beta-hemolytic Streptococci (GABHS). A 2012 meta-review and a 2016 Cochrane systematic review reported favorably on the comparative efficacy and safety of clarithromycin in pediatric patients with URTIs and in adults with GABHS pharyngitis. In this paper, the evidence base for clarithromycin in patients with URTIs is augmented by a meta-analysis of comparative studies in GABHS pharyngitis. Methods A series of five outpatient trials of clarithromycin for the treatment of streptococcal pharyngitis from an internal database were subjected to meta-analysis. Active comparators comprised penicillin VK and erythromycin. Results Rates of clinical cure or improvement were very similar in all treatment assignments, but the rates of bacteriological cure were numerically higher with clarithromycin than with comparator antibiotics. Adverse events data indicated that clarithromycin was generally well tolerated in these studies, with a relatively low incidence of adverse events and few severe incidents. Discussion Though currently not advised as a first-line therapy for URTI in most guidelines, the results of the meta-analysis indicate that clarithromycin is nevertheless a valid, effective and largely well-tolerated treatment option for GABHS pharyngitis patients who cannot benefit from other agents.

Emergence of dominant toxigenic M1T1 Streptococcus pyogenes clone during increased scarlet fever activity in England: a population-based molecular epidemiological study. THE LANCET. INFECTIOUS DISEASES 2019; 19:1209-1218. [PMID: 31519541 PMCID: PMC6838661 DOI: 10.1016/s1473-3099(19)30446-3] [Citation(s) in RCA: 85] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Revised: 07/19/2019] [Accepted: 08/12/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Since 2014, England has seen increased scarlet fever activity unprecedented in modern times. In 2016, England's scarlet fever seasonal rise coincided with an unexpected elevation in invasive Streptococcus pyogenes infections. We describe the molecular epidemiological investigation of these events. METHODS We analysed changes in S pyogenes emm genotypes, and notifications of scarlet fever and invasive disease in 2014-16 using regional (northwest London) and national (England and Wales) data. Genomes of 135 non-invasive and 552 invasive emm1 isolates from 2009-16 were analysed and compared with 2800 global emm1 sequences. Transcript and protein expression of streptococcal pyrogenic exotoxin A (SpeA; also known as scarlet fever or erythrogenic toxin A) in sequenced, non-invasive emm1 isolates was quantified by real-time PCR and western blot analyses. FINDINGS Coincident with national increases in scarlet fever and invasive disease notifications, emm1 S pyogenes upper respiratory tract isolates increased significantly in northwest London in the March to May period, from five (5%) of 96 isolates in 2014, to 28 (19%) of 147 isolates in 2015 (p=0·0021 vs 2014 values), to 47 (33%) of 144 in 2016 (p=0·0080 vs 2015 values). Similarly, invasive emm1 isolates collected nationally in the same period increased from 183 (31%) of 587 in 2015 to 267 (42%) of 637 in 2016 (p<0·0001). Sequences of emm1 isolates from 2009-16 showed emergence of a new emm1 lineage (designated M1UK)-with overlap of pharyngitis, scarlet fever, and invasive M1UK strains-which could be genotypically distinguished from pandemic emm1 isolates (M1global) by 27 single-nucleotide polymorphisms. Median SpeA protein concentration in supernatant was nine-times higher among M1UK isolates (190·2 ng/mL [IQR 168·9-200·4]; n=10) than M1global isolates (20·9 ng/mL [0·0-27·3]; n=10; p<0·0001). M1UK expanded nationally to represent 252 (84%) of all 299 emm1 genomes in 2016. Phylogenetic analysis of published datasets identified single M1UK isolates in Denmark and the USA. INTERPRETATION A dominant new emm1 S pyogenes lineage characterised by increased SpeA production has emerged during increased S pyogenes activity in England. The expanded reservoir of M1UK and recognised invasive potential of emm1 S pyogenes provide plausible explanation for the increased incidence of invasive disease, and rationale for global surveillance.

Abstract
OBJECTIVE To determine whether total exposure to penicillin V can be reduced while maintaining adequate clinical efficacy when treating pharyngotonsillitis caused by group A streptococci. DESIGN Open label, randomised controlled non-inferiority study. SETTING 17 primary healthcare centres in Sweden between September 2015 and February 2018. PARTICIPANTS Patients aged 6 years and over with pharyngotonsillitis caused by group A streptococci and three or four Centor criteria (fever ≥38.5°C, tender lymph nodes, coatings of the tonsils, and absence of cough). INTERVENTIONS Penicillin V 800 mg four times daily for five days (total 16 g) compared with the current recommended dose of 1000 mg three times daily for 10 days (total 30 g). MAIN OUTCOME MEASURES Primary outcome was clinical cure five to seven days after the end of antibiotic treatment. The non-inferiority margin was prespecified to 10 percentage points. Secondary outcomes were bacteriological eradication, time to relief of symptoms, frequency of relapses, complications and new tonsillitis, and patterns of adverse events. RESULTS Patients (n=433) were randomly allocated to the five day (n=215) or 10 day (n=218) regimen. Clinical cure in the per protocol population was 89.6% (n=181/202) in the five day group and 93.3% (n=182/195) in the 10 day group (95% confidence interval -9.7 to 2.2). Bacteriological eradication was 80.4% (n=156/194) in the five day group and 90.7% (n=165/182) in the 10 day group. Eight and seven patients had relapses, no patients and four patients had complications, and six and 13 patients had new tonsillitis in the five day and 10 day groups, respectively. Time to relief of symptoms was shorter in the five day group. Adverse events were mainly diarrhoea, nausea, and vulvovaginal disorders; the 10 day group had higher incidence and longer duration of adverse events. CONCLUSIONS Penicillin V four times daily for five days was non-inferior in clinical outcome to penicillin V three times daily for 10 days in patients with pharyngotonsillitis caused by group A streptococci. The number of relapses and complications did not differ between the two intervention groups. Five day treatment with penicillin V four times daily might be an alternative to the currently recommended 10 day regimen. TRIAL REGISTRATION EudraCT 2015-001752-30; ClinicalTrials.gov NCT02712307.

Abstract
OBJECTIVES The purpose of this study was to demonstrate the feasibility of implementing a Clinical Laboratory Improvement Amendments-waived real-time polymerase chain reaction (PCR) molecular test into a community pharmacy setting as part of a collaborative influenza and group A Streptococcus (GAS) disease management program. SETTING AND PARTICIPANTS Two community pharmacy sites in Tennessee. PRACTICE DESCRIPTION Patients presenting to the pharmacy with symptoms consistent with influenza or GAS from November 1, 2016, to April 30, 2018. PRACTICE INNOVATION Influenza and GAS management programs based on previously developed protocols occurred at 2 community pharmacies in Tennessee. Pharmacies used the Cobas Liat testing system (Roche Diagnostics). Based on test results and under a collaborative practice agreement, pharmacists dispensed prescription medications for patients with a positive test: oseltamivir for influenza and amoxicillin for GAS. Patients with negative tests were treated with over-the-counter (OTC) medications or referred. Patients testing negative for GAS were asked to consent to having a second throat swab sent for culture. EVALUATION Number of patients tested, point-of-care test results, and treatment received. RESULTS Two hundred and two patients received care at the 2 pharmacies (116 for influenza, 46 for GAS, and 43 for both). Sixty (38%) tested positive for influenza, with 51 receiving an antiviral prescription, and 16 (18%) tested positive and were treated for GAS. No patient testing negative for either or positive for influenza was dispensed an antibiotic. For patients consenting to a follow-up culture, all GAS cultures sent for confirmatory testing were negative. CONCLUSION A protocol-driven community pharmacy-based disease management program using real-time PCR testing for influenza and GAS was able to offer appropriate treatment to patients without overuse of antibiotics.

Abstract
OBJECTIVES To describe antibacterial prescribing patterns in outpatients aged 0-5 years from 2007 to 2013 in the Emilia-Romagna region, assessing sex- and age-specific consumption over time. METHODS All children aged 0-5 years resident in the Emilia-Romagna region who received at least one prescription of a systemic antibacterial in the period 2007-13 were enrolled. The prescriptions of systemic antibacterials to children were collected from the regional prescription database. Data were stratified by year, sex and age, and analysed in terms of periodic prevalence and of annual prescription rate per 1000 person-years. RESULTS The prevalence of children receiving at least one prescription per year varied from 68.0% in 2007 to 59.0% in 2013, while the average prevalence of children receiving five or more prescriptions per year was 6.96%. The annual prescription rate varied from 1621.26 in 2007 to 1372.27 in 2013. Penicillins + β-lactamase inhibitors accounted for 35.3% of total prescriptions, followed by extended-spectrum penicillins (28.6%), macrolides (17.0%) and third-generation cephalosporins (13.9%). CONCLUSIONS Despite recommendations, a significant overprescription of antibacterials to children still exists, showing no satisfactory improvements over the years. In contrast to Northern European countries, adherence to evidence-based guidelines was poor, with frequent prescribing of broad-spectrum agents for the treatment of mostly viral childhood infectious disease.

Abstract
BACKGROUND AND OBJECTIVE Acute tonsillitis is one of the most common reasons for application to otorhinolaryngology clinics. In the treatment of acute tonsillitis, supportive therapies are mostly used. As antibiotic therapy, penicillin or erythromycin can be used. The aim of this study is to decrease the clinical recovery time of acute tonsillitis by providing parenteral treatment and daily cleaning of tonsillar lesions. MATERIAL AND METHODS Patients with an age range of 15-60 years were included in the study. The patients were divided into two groups. The first group used an i.v. combination of ampicillin + sulbactam and the tonsillar membranes of patients were cleaned daily. The second group used only the i.v. combination of ampicillin + sulbactam. RESULTS Patients who received antibiotherapy and debridement had a clinical improvement of 90% on the 2nd treatment day and 95% on the 5th treatment day. The patients receiving only antibiotics had a clinical improvement of 65% on the 5th treatment day and 75% on the 7th treatment day. The recovery time of both groups was significantly different (p < 0.05). CONCLUSION The solution and technique used in this clinical study showed that patients with acute tonsillitis could recover in a very short time without any complications.

Abstract
BACKGROUND Streptococcus pyogenes is the most common cause of bacterial pharyngitis. Genotyping of emm is useful for molecular epidemiological survey of S. pyogenes. Antibiotic resistance data are needed for empirical treatments. METHODS In total, 358 children in Changwon, Korea who had pharyngitis symptoms were subjected to throat cultures to isolate S. pyogenes in 2017. emm genotyping was performed by direct sequencing. An antibiotic susceptibility test was performed using the disk diffusion method for erythromycin (ERY), clindamycin (CLI), tetracycline (TET) and ofloxacin (OFX). Screening for macrolide resistance phenotype and its determinants was performed for the ERY-resistant strains. RESULTS A total of 190 strains (53.1 %) of S. pyogenes were isolated from 358 children. The most frequent emm genotype was emm4 (53.2 %), followed by emm89 (12.6 %), emm28 (11.6 %) and emm1 (10 %). Antibiotic resistance rates to ERY, CLI, TET and OFX were 3.2 %, 2.6 %, 1.1 % and 2.6%, respectively. There were five isolates of the cMLSB phenotype having the ermB gene and one M phenotype harbouring the mefA gene. CONCLUSIONS The distribution of emm genotypes was quite different from those previously reported in Korea. emm4 accounted for more than 50 % of the genotypes. Macrolide resistance rates remained very low, but five of six ERY-resistant strains displayed the cMLSB phenotype.

Abstract
Aims Explore the effect of compound lobelia oral liquid on acute pharyngitis rabbits model caused by ammonium hydroxide, evaluate its curative effect. Methods Acute pharyngitis rabbit model was prepared by ammonia spray at pharyngeal. After 1 h of the last administration, score the pharyngeal tissue symptoms of rabbits under the condition of naked eyes (score according to the score criteria). Then, take blood from the marginal auricular vein for routine blood tests and serum TNF-α level measure. Take pharyngeal tissue for HE staining, and observe its pathological changes under the microscope. Results Compared with the blank group, the pharyngeal tissue symptom score and serum TNF-α level in the model group were significantly increased (P < 0.01). The results of blood routine showed that the number of white blood cells and lymphocytes in the model group increased significantly (P < 0.01), and neutrophilic granulocyte percentage decreased significantly (P < 0.01). The infiltration of inflammatory cells in the pharynx tissue was obvious and pathological changes were observed. Compared with the model group, large, middle and small doses of compound lobelia oral liquid group could reduce the scores of pharyngeal tissue symptoms in rabbits with acute pharyngitis induced by ammonia. The large and middle dose compound lobelia oral liquid group could significantly reduce serum TNF-α level and neutrophilic granulocyte percentage, significantly increase the number of white blood cells and lymphocytes (P < 0.01); The small dose compound lobelia oral liquid group could significantly reduce the number of white blood cells and lymphocytes (P < 0.01), there was an increasing tendency to neutrophils and a decreasing tendency to serum TNF-α, but no statistical significance. The large, middle and small doses of compound lobelia oral liquid group all could improve the pathological changes of pharyngeal tissue inflammatory infiltration. Conclusion Compound lobelia oral liquid has a good effect on rabbit acute pharyngitis model caused by ammonia.

Abstract
OBJECTIVE Fever is a very common adaptive immune response in acute respiratory tract disorders during infancy. Antipyretic / analgesic drugs such as paracetamol (acetaminophen) are widely used to improve the comfort of the child but may cause medically unneeded antipyresis and rare but potentially serious side effects. We assess whether treatment with Pelargonium sidoides extract EPs 7630 reduces the administration of paracetamol in children with acute tonsillopharyngitis (ATP) or acute bronchitis (AB). DESIGN Meta-analysis of randomised, placebo-controlled clinical trials. METHODS We searched clinical trial registries (ISRCTN, ClinicalTrials.gov ) and medical literature (MEDLINE, EMBASE), for randomised, placebo-controlled trials investigating the administration of EPs 7630 to children with ATP or AB and reporting the co-administration of paracetamol. Based on the individual participant data of the eligible trials, study populations were characterized according to sex and age, and meta-analyses were performed for cumulative paracetamol use and ability to attend school at treatment end. RESULTS Six trials including a total of 523 children aged 6-10 years (EPs 7630: 265; placebo: 258) and suffering from non-β-hemolytic streptococcal ATP (3 trials) or from AB (3 trials) were identified and eligible. Children received EPs 7630 or placebo for 6 (ATP) or 7 days (AB). Compared to placebo, EPs 7630 reduced the cumulative dose of paracetamol in 5 out of the 6 trials, by an average of 244 mg (Hedges' g; - 0.28; 95% confidence interval: [- 0.53; - 0.02]; p < 0.03). At treatment end, 30.2% (EPs 7630) and 74.4% (placebo) of the children were still unable to attend school (risk ratio: 0.43; 95% confidence interval: [0.29; 0.65]; p < 0.001). CONCLUSIONS In children aged 6-10 years with AB or ATP, EPs 7630 alleviated the symptom burden and accelerated recovery. Although EPs 7630 has no known antipyretic effect, concomitant use of paracetamol was reduced.

Abstract
Clarithromycin and azithromycin are second-generation macrolides established and widely used for treating a range of upper and lower respiratory tract infections. Extensive clinical trials data indicate that these drugs are highly effective in these applications and broadly comparable in their clinical and microbiological effectiveness. However, consideration of pharmacokinetic, metabolic, and tissue-penetration data, including the significant antibacterial activity of the metabolite 14-hydroxy-clarithromycin, plus the findings of pharmacodynamic modeling, provide evidence that the long half-life and lower potency of azithromycin predispose this agent to select for resistant isolates. Comparison of the "mutant-prevention concentrations" of clarithromycin and azithromycin, and examination of large-scale epidemiological data from Canada, also support the view that these drugs differ materially in their propensity to promote resistance among bacterial strains implicated in common respiratory infections, and that clarithromycin may offer important advantages over azithromycin that should be considered when choosing a macrolide to treat these conditions.

Association between rapid antigen detection tests and antibiotics for acute pharyngitis in Japan: A retrospective observational study. J Infect Chemother 2019; 25:267-272.

Abstract
The application and clinical impact of rapid antigen detection test (RADT) in the treatment of acute pharyngitis is unknown in Japan. We aimed to examine the proportions of RADT usage to identify Group A β-hemolytic Streptococcus (GAS) in outpatients with acute pharyngitis and evaluate the association between RADT and antibiotic treatment. We analyzed health insurance claims data from 2013 to 2015. Logistic regression models were used to analyze associated factors with RADT, overall antibiotic prescription, or penicillin use. We analyzed 1.27 million outpatient visits with acute pharyngitis, in which antibiotics were prescribed in 59.3% of visits. Of the total visits, 5.6% of patients received RADT, and 10.8% of the antibiotics were penicillin. Penicillin selection rates were higher in cases with RADT (25.4%) than those without RADT (9.7%). Compared to large-scale facilities, antibiotic prescription rates were higher in physicians' offices. For factor analysis, age (3-15 years), diagnosis code (streptococcal pharyngitis), size of the medical facility (large-scale hospitals), and physician's specialty (pediatrics) were associated with RADT use. Penicillin selection rate increased with RADT implementation (25.4% vs. 9.7%: adjusted odds ratio 1.55; 95% CI, 1.50-1.60). At 63% of the facilities, the RADT implementation rate was <5% of acute pharyngitis visits prescribed antibiotics. In conclusion, the proportion of RADT usage for outpatients with acute pharyngitis was low in Japan. With appropriate indication and evaluation, we expect that more utilization of RADT can help promote antimicrobial stewardship for outpatients with acute pharyngitis by prompting penicillin therapy. Further investigation with detailed clinical data are warranted.

Abstract
Evidence-based treatment guidelines for managing infections in health care are promoted as tools to prevent unnecessary use of antibiotics. Antibiotic misuse has been examined as regards the doctor-patient relation and the social context of medical practice. Less attention has been paid to how the very conceptualisation of human-microbial relations may influence understandings of antibiotic misuse. The article examines a medical controversy concerning guidelines for managing throat infection and antibiotic treatment in Sweden. It demonstrates how this controversy unfolds around two different ways of relating to a specific bacterium - Group A Streptococcus. The analysis shows how two 'microbiopolitics', involving different understandings of human-microbial relations, are created in the controversy and how different antibiotic prescribing practices are justified. By focusing on Group A Streptococcus, which is commonly observed, but also unpredictable and potentially dangerous, the article provides new insights into the relations between bacteria, humans and policy in an age of antimicrobial resistance. It argues, in particular, that the definition of antibiotic misuse is unstable and consequently that policy measures aimed at reducing misuse must be related to how specific infections and bacteria are conceptualised in the actual context the policy addresses.

Abstract
Despite group A streptococci being an infrequent cause of pharyngitis in adult outpatients, sore throat remains a common indication for antibiotic prescription. This prospective multicentre non-randomised study describes a community pharmacy-based antimicrobial stewardship intervention consisting in the implementation of rapid antigen testing (RAT) for the management of adults with sore throat. Trained pharmacists triaged patients presenting with symptoms of pharyngitis using the modified Centor score. Those at risk for streptococcal infection were tested with RAT. Patients with a positive RAT were invited to consult a physician, whereas others were offered a symptomatic treatment. All patients received educational leaflets and were asked to fill in a follow-up form 7 days later. Ninety-eight pharmacies in one French region participated, and 559 patients were included over 6 months. RAT was proposed in 367 (65.7%) cases, and it was positive in 28 (8.3%). The follow-up form was returned by 140 (38.5%) participants. Of these, 10/10 patients with positive RAT further consulted a physician and were prescribed an antibiotic treatment, whereas 96.5% (110/114) of patients with negative results and not having any other reason to seek for doctor's advice did not consult. All participants found the intervention useful. Pharmacists spent 6-15 min to perform the intervention, and 98.6% (73/74) of pharmacists giving a feedback declared to be ready to implement this intervention in daily practice, if endorsed and reimbursed. Our results suggest that a pharmacy-based programme for the management of sore throat is feasible and could increase adherence to guidelines.

Abstract
BACKGROUND AND OBJECTIVES The importance of Streptococcus dysgalactiae subsp. equisimilis (SDSE) in causing sporadic pharyngitis in children remains controversial. The aims of this study were (1) to report the incidence and (2) to compare the epidemiologic and clinical features of patients with SDSE to those with Streptococcus pyogenes (SP). METHODS A prospective study was conducted on acute pharyngitis associated with SDSE in children over a 2-year period. SDSE was identified using a phenotypic method, M protein gene (emm) analysis and matrix-assisted laser desorption ionization-time of flight mass spectrometry. Patients with positive SDSE or SP cultures received cephalosporins for 5 days and were followed up. The emm genotyping and specific virulence genes analyses were performed. RESULTS From 3416 throat cultures, 67 isolates (2.0%) were identified as SDSE and 515 (15.1%) were identified as SP. The mean age of patients with SDSE (8.3 years) was older than those with SP (6.6 years; P < 0.01). There was minimal seasonal variation in the isolation rates of SDSE. The febrile patients' rates, gender distribution, cervical lymph node adenopathy rates, hospitalization rates, eradication and failure rates and the nonsuppurative sequelae between patients with SDSE and SP were similar. All SDSE isolates possessed important virulence genes. The emm genotyping of SDSE showed high strain diversity. CONCLUSIONS The incidence of acute pharyngitis associated with accurately identified SDSE was 2/15 of that with SP. Epidemiologic and clinical features of acute pharyngitis associated with SDSE are indistinguishable from those with SP, with the exception of age and seasonal variation.

Abstract
INTRODUCTION Bacterial resistance burden has increased in the past years, mainly due to inappropriate antibiotic use. Recently it has become an urgent public health concern due to its impact on the prolongation of hospitalization, an increase of total cost of treatment and mortality associated with infectious disease. Almost half of the antimicrobial prescriptions in outpatient care visits are prescribed for acute upper respiratory infections, especially rhinosinusitis, otitis media, and pharyngotonsillitis. In this context, otorhinolaryngologists play an important role in orienting patients and non-specialists in the utilization of antibiotics rationally and properly in these infections. OBJECTIVES To review the most recent recommendations and guidelines for the use of antibiotics in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, adapted to our national reality. METHODS A literature review on PubMed database including the medical management in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, followed by a discussion with a panel of specialists. RESULTS Antibiotics must be judiciously prescribed in uncomplicated acute upper respiratory tract infections. The severity of clinical presentation and the potential risks for evolution to suppurative and non-suppurative complications must be taken into 'consideration'. CONCLUSIONS Periodic revisions on guidelines and recommendations for treatment of the main acute infections are necessary to orient rationale and appropriate use of antibiotics. Continuous medical education and changes in physicians' and patients' behavior are required to modify the paradigm that all upper respiratory infection needs antibiotic therapy, minimizing the consequences of its inadequate and inappropriate use.

Abstract
Objective Antibiotic treatment of Group A Streptococcus (GAS) pharyngitis is important in acute rheumatic fever (ARF) prevention, however clinical guidelines for prescription vary. GAS carriers with acute viral infections may receive antibiotics unnecessarily. This review assessed the prevalence of GAS pharyngitis and carriage in different settings. Methods A random-effects meta-analysis was performed. Prevalence estimates for GAS+ve pharyngitis, serologically-confirmed GAS pharyngitis and asymptomatic pharyngeal carriage were generated. Findings were stratified by age group, recruitment method and country income level. Medline and EMBASE databases were searched for relevant literature published between 1 January 1946 and 7 April 2017. Studies reporting prevalence data on GAS+ve or serologically-confirmed GAS pharyngitis that stated participants exhibited symptoms of pharyngitis or upper respiratory tract infection (URTI) were included. Included studies reporting the prevalence of asymptomatic GAS carriage needed to state participants were asymptomatic. Results 285 eligible studies were identified. The prevalence of GAS+ve pharyngitis was 24.1% (95% CI: 22.6–25.6%) in clinical settings (which used ‘passive recruitment’ methods), but less in sore throat management programmes (which used ‘active recruitment’, 10.0%, 8.1–12.4%). GAS+ve pharyngitis was more prevalent in high-income countries (24.3%, 22.6–26.1%) compared with low/middle-income countries (17.6%, 14.9–20.7%). In clinical settings, approximately 10% of children swabbed with a sore throat have serologically-confirmed GAS pharyngitis, but this increases to around 50–60% when the child is GAS culture-positive. The prevalence of serologically-confirmed GAS pharyngitis was 10.3% (6.6–15.7%) in children from high-income countries and their asymptomatic GAS carriage prevalence was 10.5% (8.4–12.9%). A lower carriage prevalence was detected in children from low/middle income countries (5.9%, 4.3–8.1%). Conclusions In active sore throat management programmes, if the prevalence of GAS detection approaches the asymptomatic carriage rate (around 6–11%), there may be little benefit from antibiotic treatment as the majority of culture-positive patients are likely carriers. Treating sore throats caused by Group A Streptococcus infections (GAS pharyngitis) with antibiotics is important for preventing acute rheumatic fever (ARF). It is impossible to distinguish patients with true GAS pharyngitis infections from GAS carriers with pharyngitis caused by viral infections when throat swab culturing alone is used to diagnose GAS pharyngitis. Carriers are not likely to benefit from antibiotic treatment, but may receive treatment unnecessarily. Reported rates of GAS pharyngitis and carriage vary considerably depending on the setting. Thus it is difficult to ascertain which groups are likely to benefit significantly from active sore throat management programmes which treat GAS pharyngitis in order to prevent ARF. We performed a meta-analysis to estimate the prevalence of GAS pharyngitis and asymptomatic carriage in different settings. Approximately 10% of all children swabbed for a sore throat in clinical settings have true GAS pharyngitis, but this increases to around 55% if the children have GAS detected in their throat using swab cultures. In active sore throat management programmes, the prevalence of GAS detection is lower than in clinical settings and if it declines towards 8% (the asymptomatic carriage level), there may be little benefit in treating GAS culture-positive patients with antibiotics.

In the present study, essential oils (EOs) extracted from oregano, sage, cloves, and ginger were evaluated for the phytochemical profile, antibacterial, and anti-biofilm activities against Streptococcus pyogenes. The broth microdilution method was used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of EOs. The minimum biofilm inhibitory concentrations (MBICs) were determined using MTT assay and fixed biofilms were observed through scan electron microscopy. The oregano and sage EOs showed the lowest MIC as well as MBC of 0.25-0.5 mg/mL. Time kill assay results showed that oregano and sage EOs exhibited bactericidal effects within 5 min and 4 h, respectively. Both oregano and sage extracts acts as a potent anti-biofilm agent with dual actions, preventing and eradicating the biofilm. The microscopic visualization of biofilms treated with EOs have shown morphological and density changes compared to the untreated control. Oregano EO was constituted predominantly carvacrol (91.6%) and in sage EO, higher levels of α-thujone (28.5%) and camphor (16.6%) were revealed. EOs of oregano and sage inhibit the growth and biofilm formation of S. pyogenes. Effective concentrations of oregano and sage EOs and their phytochemicals can be used in developing potential plant-derived antimicrobial agents in the management of streptococcal pharyngitis.

Abstract
Introduction Despite its in vitro efficacy, penicillin often fails to eradicate Group A β-hemolytic streptococci (GABHS) from patients with acute and relapsing pharyngo-tonsillitis (PT). Objective This review of the literature details the causes of penicillin failure to eradicate GABHS PT and the therapeutic modalities to reduce and overcome antimicrobial failure. Data Synthesis The causes of penicillin failure in eradicating GABHS PT include the presence of β lactamase producing bacteria (BLPB) that "protect" GABHS from any penicillin; the absence of bacteria that interfere with the growth of GABHS; co-aggregation between GABHS and Moraxella catarrhalis; and the poor penetration of penicillin into the tonsillar tissues and the tonsillo-pharyngeal cells, which allows intracellular GABHS and Staphylococcus aureus to survive. The inadequate intracellular penetration of penicillin can allow intracellular GABHS and S. aureus to persist. In the treatment of acute tonsillitis, the use of cephalosporin can overcome these interactions by eradicating aerobic BLPB (including M. catarrhalis), while preserving the potentially interfering organisms and eliminating GABHS. Conclusion In treatment of recurrent and chronic PT, the administration of clindamycin, or amoxicillin-clavulanic acid, can eradicate both aerobic and anaerobic BLPB, as well as GABHS. The superior intracellular penetration of cephalosporin and clindamycin also enhances their efficacy against intracellular GABHS and S. aureus.

Abstract
These guidelines were developed as part of the 2016 Policy Research Servicing Project by the Korea Centers for Disease Control and Prevention. A multidisciplinary approach was taken to formulate this guideline to provide practical information about the diagnosis and treatment of adults with acute upper respiratory tract infection, with the ultimate aim to promote the appropriate use of antibiotics. The formulation of this guideline was based on a systematic literature review and analysis of the latest research findings to facilitate evidence-based practice, and focused on key questions to help clinicians obtain solutions to clinical questions that may arise during the care of a patient. These guidelines mainly cover the subjects on the assessment of antibiotic indications and appropriate selection of antibiotics for adult patients with acute pharyngotonsillitis or acute sinusitis.

Using Prescription Patterns in Primary Care to Derive New Quality Indicators for Childhood Community Antibiotic Prescribing. Pediatr Infect Dis J 2016; 35:1317-1323. [PMID: 27626915 DOI: 10.1097/inf.0000000000001324] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND To describe patterns of antibiotic outpatient use in 3 European countries, including 2 new pediatric-specific quality indicators (QIs). METHODS A cohort study was conducted, 2001-2010, using electronic primary care records of 2,196,312 children up to 14 (Pedianet, Italy) or 18 years (The Health Improvement Network, United Kingdom; Integrated Primary Care Information database, The Netherlands) contributing 12,079,620 person-years. Prevalence rates of antibiotic prescribing per year were calculated and antibiotics accounting (drug utilization) for 90% of all antibiotic prescriptions were identified (drug utilization 90% method). The ratio between users of broad to narrow-spectrum penicillins, cephalosporins and macrolides (B/N ratio) and 2 pediatric-specific QIs: the proportion of amoxicillin users (amoxicillin index) and the ratio between users of amoxicillin to broad-spectrum penicillins, cephalosporins and macrolides (A/B ratio) were determined. RESULTS The overall annual prevalence of antibiotic prescriptions was 18.0% in the Netherlands, 36.2% in the United Kingdom and 52.0% in Italy. Use was maximal in the first years of life. The number of antibiotics accounting for the drug utilization 90% was comparable. The B/N ratio varied widely from 0.3 to 74.7. The amoxicillin index was highest in the Netherlands and the United Kingdom (50-60%), lowest in Italy (30%) and worsened over time in the United Kingdom and Italy. The A/B ratio in 2010 was 0.3 in Italy, 1.7 in the Netherlands and 5.4 in the United Kingdom. CONCLUSIONS The patterns of antibiotic prescribing varied highly with age and country. The pediatric-specific QIs combined with the total prevalence rate of use provide a clear picture of the trends of community childhood antibiotic prescribing, allowing monitoring of the impact of policy interventions.

Abstract
Aim: This study assessed multiple doses of flurbiprofen 8.75 mg lozenges for the relief of three prominent symptoms of acute pharyngitis: pain intensity (primary end point), difficulty swallowing and swollen throat. Patients & methods: A total of 204 patients (102 in each group) with confirmed pharyngitis (onset ≤4 days) were randomly assigned to take up to five flurbiprofen or placebo lozenges every 3–6 h, for 7 days. Using validated rating scales (sore throat pain intensity, difficulty swallowing and swollen throat) patients rated their symptoms for the duration of the study. Results: Over the first 24 h, patients treated with flurbiprofen lozenges reported significantly greater reductions in sore throat pain (47%) as well as difficulty swallowing (66%) and swollen throat (40%) compared with placebo (all p < 0.05). Conclusion: Multiple doses of flurbiprofen lozenges provide effective relief of sore throat pain intensity as well as difficulty swallowing and swollen throat.

Abstract
OBJECTIVES The UK 5 year antimicrobial resistance strategy recognizes the role of point-of-care diagnostics to identify where antimicrobials are required, as well as to assess the appropriateness of the diagnosis and treatment. A sore throat test-and-treat service was introduced in 35 community pharmacies across two localities in England during 2014-15. METHODS Trained pharmacy staff assessed patients presenting with a sore throat using the Centor scoring system and patients meeting three or all four of the criteria were offered a throat swab test for Streptococcus pyogenes, Lancefield group A streptococci. Patients with a positive throat swab test were offered antibiotic treatment. RESULTS Following screening by pharmacy staff, 149/367 (40.6%) patients were eligible for throat swab testing. Of these, only 36/149 (24.2%) were positive for group A streptococci. Antibiotics were supplied to 9.8% (n = 36/367) of all patients accessing the service. Just under half of patients that were not showing signs of a bacterial infection (60/123, 48.8%) would have gone to their general practitioner if the service had not been available. CONCLUSIONS This study has shown that it is feasible to deliver a community-pharmacy-based screening and treatment service using point-of-care testing. This type of service has the potential to support the antimicrobial resistance agenda by reducing unnecessary antibiotic use and inappropriate antibiotic consumption.
