[Antibacterial therapy for acute streptococcal tonsillopharyngitis: results of a randomized comparative clinical trial with amoxicillin + clavulanic acid EXPRESS].

BACKGROUND: Acute tonsillopharyngitis is one of the most common types of respiratory tract infections. In case of bacterial etiologies of the disease, penicillin antibiotics are prescribed, in particular amoxicillin + clavulanic acid. Dispersible forms of antibiotics have a number of advantages over film-coated tablets and are characterized by better pharmacokinetic parameters that increase the effectiveness and safety of treatment, as well as patient compliance. AIM: To compare the effectiveness and safety of Amoxicillin + Clavulanic acid EXPRESS in the form of dispersible tablets and amoxicillin with clavulanic acid in film-coated tablets in the treatment of acute streptococcal tonsillopharyngitis. MATERIALS AND METHODS: A randomized comparative clinical study involved 60 adult patients diagnosed with acute streptococcal tonsillopharyngitis. Group 1 (n=30) received the Amoxicillin + Clavulanic acid EXPRESS, dispersible tablets, 875+125 mg 2 times a day at the beginning of meals. Group 2 (n=30) received Amoxiclav, film-coated tablets, 875+125 mg 2 times a day at the beginning of meals. The duration of the treatment was 10 days. The following procedures were performed to all participants: general clinical and otorhinolaryngological examinations, an express test to detect group A streptococcal antigens in a smear from the posterior pharyngeal wall (streptatest), assessment of symptoms of acute tonsillopharyngitis on the McIsaac scale, severity of sore throat, difficulty swallowing, swelling of the throat, measurement of body temperature, assessment of the clinical global impression of the therapy, adherence to treatment, frequency of the adverse reactions before treatment, 3 days after the beginning of therapy and after the course completion (day 10). RESULTS: Recovery occurred in 96.6% of patients in group 1 according to examination on the 10th day of treatment and in 93.3% of patients in group 2. The rate of fever regression was higher in group 1 - on the 3rd day of treatment, normalization of temperature was observed in 36.6% and 30% of patients in the comparison group. Pain syndrome, symptoms of throat swelling and difficulty swallowing significantly (p<0.01) regressed by the 10th day in patients of both treatment groups. The incidence of adverse reactions on the 10th day of treatment in group 1 was 10%, in group 2 - 33.3% (p=0.03). CONCLUSION: Amoxicillin + Clavulanic acid EXPRESS has high therapeutic efficacy in the treatment of acute streptococcal tonsillopharyngitis, comparable to the Amoxiclav in film-coated tablets. At the same time, dispersible tablets of Amoxicillin + Clavulanic acid EXPRESS demonstrated a significantly higher safety profile compared to the simple tablet form.

The Effects of a Dietary Supplement (PediaFlù) Plus Standard of Care in Children With Acute Tonsillopharyngitis/Rhinopharyngitis: Protocol for a Randomized Controlled Trial.

BACKGROUND: A dietary supplement containing Pelargonium sidoides extract, propolis, zinc, and honey has been recently developed and proven to be an effective adjuvant in clinical practice for seasonal diseases and the treatment of respiratory tract disorders. OBJECTIVE: This trial aims to verify the efficacy of the tested dietary supplement in a pediatric population with acute tonsillopharyngitis/rhinopharyngitis (ATR). METHODS: The trial includes children aged between 3 and 10 years with ATR ≤48 h, a negative rapid test for beta-hemolytic streptococcus or culture identification of nasal and/or pharyngeal exudates, and SARS-CoV-2 infection. The dietary supplement tested is an oral solution already on the market based on Pelagon P-70 (equivalent to Pelargonium sidoides d.e. 133.3 mg/100 ml), propolis, zinc, and honey. The product is administered at 5 ml 3 times a day for 6 days for children younger than 6 years and 10 ml 3 times a day for 6 days for children older than 6 years. The study design is open label, randomized, and controlled, with the tested dietary supplement plus standard of care (SoC) versus SoC alone. Patients are enrolled from 3 sites in Romania. The change in Tonsillitis Severity Score and number of treatment failures (using ibuprofen or high-dose paracetamol as rescue medication) are the primary end points. Based on the Tonsillitis Severity Score and the 2-sample comparison of the means formula with a 5% significance level, 80% power, and a minimally clinically important difference of 2 (SD 3.85) points, 120 patients are required. To account for potential screening failures and dropouts, we need to screen a population of approximately 150 children. RESULTS: Patient enrollment began on June 3, 2021 (first patient's first visit), and ended on August 12, 2021 (last patient's last visit). The data collection period was from June 3, 2021, to September 16, 2021. The study was funded in February 2023. Data analysis is currently ongoing (April 2024). We expect the results to be published in a peer-reviewed clinical journal in the third quarter of 2024 and presented at scientific meetings in the last quarter of 2024. CONCLUSIONS: The data from this trial may help identify new adjuvant treatments for children with ATR when streptococcal infection is excluded by a negative rapid test, thereby avoiding unnecessary antibiotic administration.

Relation of Streptococcus Pyogenes tonsillitis isolate to antimicrobial agents and its infection treatment.

We reported the case of tonsillitis treatment in a 17-years-old boy with use of chemical non-antibiotic preparations, plant derived products and antibiotic benzathine phenoxymethylpenicillin. The antimicrobial agents for treatment were selected on the basis of their activity against a disease agent, the group A ß-hemolytic strain Streptococcus pyogenes BS1 isolated from a patient. The bacterium was susceptible in vitro to ß-lactams, with largest zones conditioned by penicillin G and benzathine phenoxymethylpenicillin discs, to fluoroquinolones and to cephems, with exception of cefazolin. Lincosamide clindamycin, macrolide spiramycin, aminoglycoside gentamicin, erythromycin, tetracycline and combination of sulfamethoxazole and trimethoprim were inactive against this bacterium. The Streptococcus pyogenes BS1 demonstrated intermediate susceptibility to the cephalosporin cephalexin, fluoroquinolone lomefloxacin and glycopeptide vancomycin. Non-antibiotic preparations were evaluated against Streptococcus pyogenes BS1 also. Among them "Stomatidin", "Chlorophyllipt", and phages of "Pyofag" were more effective than "Decatylen", "Decasan" and "Furadonin" in vitro. The antimicrobial applications of "Stomatidin", "Chlorophyllipt" and phages of "Pyofag" in the patient were less effective compared to the result of antibiotic benzathine phenoxymethylpenicillin treatment. Complete recovery of the patient was achieved with use of this antibiotic and Calendula flower extract as an local anti-inflammatory agent.

Unilateral tonsillitis due to primary syphilis with gram-negative corkscrew-like spirochaetes confirmed by Gram stain of pus.

A man in his 40s presented with pharyngeal pain and right cervical lymphadenopathy that persisted for 1 month. His right tonsil was swollen and covered with exudate; however, a rapid streptococcal antigen test was negative. Rapid plasma reagin and Treponema pallidum antibody were positive. Gram staining of the pus confirmed the presence of gram-negative corkscrew-like spirochaetes. The patient had unprotected oral intercourse. He did not have any skin lesions. He was diagnosed with primary syphilis and treated with benzathine penicillin G. In adults, the differential diagnosis of tonsillitis should include sexually transmitted diseases. A rapid streptococcal antigen test is not sufficient for such a case; a syphilis test is necessary, and Gram staining, which is rapid and does not need any special equipment, can support the diagnosis.

Efficacy, safety, and tissue penetration of solithromycin in Japanese patients with otorhinolaryngological infections.

OBJECTIVE: To assess the efficacy, safety, and tissue penetration of solithromycin for the treatment of otorhinolaryngological infections, we conducted three studies: a tissue penetration study with patients scheduled to undergo otorhinolaryngological tissue removal, an open-label study comprising patients with otitis media, pharyngitis, laryngitis, and tonsillitis, and a non-inferiority study compared with high-dose cefcapene-pivoxil (CFPN-PI). METHODS: Tissue penetration study; 17 patients with chronic rhinosinusitis, chronic otitis media, chronic tonsillitis, or palatine tonsillar hypertrophy, who required resection or removal of their tissue, were enrolled. Solithromycin was administered orally, and otorhinolaryngological tissues were collected 3.5-6 h after drug administration; blood was collected within 15 min before and after drug administration. The collected tissues and blood concentrations were measured at a central laboratory. Open-label study; 55 patients who were diagnosed with acute otitis media, laryngopharyngitis, or tonsillitis were enrolled. Solithromycin was administered orally 800 mg on Day 1, while on days 2-7, 400 mg of the drug was administered once daily. The primary endpoint is the clinical response at Test-of-Cure (TOC: 5-10 days after completion) Non-inferiority study; 283 patients with acute rhinosinusitis or acute exacerbation of chronic rhinosinusitis were randomized into either the solithromycin group or CFPN-PI group. Solithromycin was administered 800 mg once daily on Day 1 and 400 mg once daily while on Days 2-7 in solithromycin group, and CFPN-PI was administered 150 mg three times a day while on Days 1-7 in CFPN-PI group. The primary endpoint is the clinical response at TOC. RESULTS: In the tissue penetration study, the tissue concentration ratios (tissue concentration/plasma concentration) of solithromycin were 4.19 in the sinonasal mucosa, 1.33 in the middle ear mucosa, and 6.12 in the palatine tonsil tissue. In the open-label study, the efficacy rates at the TOC were 97.0 % for acute otitis media, 100 % for laryngopharyngitis, and 81.8 % for tonsillitis. In the non-inferiority study comprising patients with rhinosinusitis, the efficacy rate at the TOC was 87.7 % for solithromycin and 89.7 % for CFPN-PI. The difference in the efficacy rate (95 % confidence interval) was -2.0 % (-9.4 % to 5.4 %), verifying the non-inferiority of solithromycin to CFPN-PI. The most common adverse events in patients administered solithromycin were diarrhea (20.7 %), nausea and nasopharyngitis (3.6 %,), pharyngitis and elevated hepatic function test results (3.1 %), and abnormal hepatic function (2.1 %). CONCLUSION: Based on the findings, it is suggested that solithromycin is useful for the treatment of otorhinolaryngological infections.

Post-tonsillectomy Hemorrhage in Patients Receiving Ketorolac Analgesic.

Background Ketorolac, the non-steroidal anti-inflammatory drug, is thought to have less sedation as well as postoperative nausea and vomiting in comparison to opioids, but with higher risk of post-tonsillectomy hemorrhage as reported in some of the literatures. There is no consensus till date in the use of ketorolac in the management of pain following tonsil and adenoid related surgeries. Objective To find out the incidence of hemorrhage following tonsil and adenoid related surgeries in patients receiving ketorolac in postoperative period. Method This is a retrospective chart review of patients undergoing tonsil and adenoid related surgeries who had received ketorolac during April, 2013 to May, 2019 at department of ENT-HNS, Patan Academy of Health Sciences (PAHS), Lalitpur, Nepal. Post-tonsillectomy hemorrhage rate was calculated in pediatric and adult patients. Result During the study period, 103 patients (male - 50 and female - 53) received ketorolac in postoperative period. Tonsillectomy and adenotonsillectomy were performed in 71and 32 patients respectively. Forty-five patients were < 18 years whereas 58 were ≥ 18 years. Most common indication for surgery was recurrent tonsillitis (66/103) followed by adenotonsillar hypertrophy (31/103). Post-tonsillectomy hemorrhage was observed in 15 patients; among them, four out 45 were < 18 years and 11 out of 58 ≥ 18 years. All five patients out of 15, who required surgical intervention for post-tonsillectomy hemorrhage, were ≥ 18 years and were operated for recurrent tonsillitis. Rest of the patients (10/15) were managed conservatively. None of the patients required blood transfusion. Conclusion Ketorolac is not associated with increased risk of post-tonsillectomy hemorrhage in children and can safely be administered. Whereas in adults, recurrent tonsillitis being the most common indication for tonsillectomy, it should be used cautiously.

Utilización de antibióticos en faringoamigdalitis aguda en la provincia de Albacete / Use of antibiotics in acute pharyngotonsillitis in the province of Albacete

Introducción: la faringoamigdalitis aguda (FAA) es una de las patologías más prevalentes en la población pediátrica y una de las principales causas de prescripción de antibióticos en este grupo de población. Material y métodos: estudio observacional, descriptivo de utilización de antibióticos en FAA. La muestra del estudio son todos los niños del área que durante los tres años del estudio han recibido la prescripción de un antibiótico como tratamiento de una FAA. Resultados: durante los tres años del proyecto se atendieron un total de 53 995 procesos de FAA, de los que 33 426 (61,9%) fueron tratados con antibióticos. Considerando los niños menores de 3 años, se atendieron un total de 10 901 procesos de FAA (20,2% del total de las FAA), de los que recibieron antibiótico 6494 (59,6%). En cuanto a la selección del antibiótico se utilizó preferiblemente penicilinas sensibles a betalactamasas (fenoximetilpenicilina, fenixometilpenicilina-benzatina) y amoxicilina: 60,3% el primer año, 60,9% el segundo y 66,8% el tercero; con menor uso de otros grupos antibióticos: amoxicilina-ácido clavulánico en 2475 procesos (18,2%) durante el primer año, 1754 (17,7%) durante el segundo y 1644 (16,6%) durante el tercero. También se observó menor uso de macrólidos: 2825 (20,7%) en el primer año del proyecto, 1933 (19,6%) en el segundo y 1419 (14,3%) en el último. Conclusión: el uso de amoxicilina-ácido clavulánico y de macrólidos está muy por encima de lo esperado si consideramos la baja prevalencia de estado de portador de Streptococccus pyogenes a nivel faríngeo o la baja prevalencia de alergia a penicilina en la población pediátrica (AU)

Introduction: acute tonsillitis is one of the most prevalent pathologies among the pediatric population and one of the leading causes of antibiotic prescribing in this group.Materials and methods: observational and descriptive study of the use of antibiotics in acute tonsillitis. We have included all the children from our health area who have been prescribed antibiotics as treatment of an acute tonsillitis during the three years of the study.Results: a total of 53,995 acute tonsillitis were diagnosed during the three years of the project, some of which, 33,426 (61.9%), were treated with antibiotics. In children under the age of 3 years, 10,901 cases of acute tonsillitis were diagnosed (20.2% of the tonsillitis), being treated with antibiotics 6,494 (59.6%).We have observed that the most prescribed antibiotics were beta-lactamase sensitive penicillins (phenoxymethylpenicillin, benzathine phenoxymethylpenicillin) and amoxicillin: 60.3% in the first year, 60.9% in the second one and 66.8% in the third year, meanwhile other groups of antibiotics were less commonly used: amoxicillin/clavulanic acid in 2,475 cases (18.2%) in the first year of the study, 1,754 (17.7%) in the second and 1,644 (16.6%) in the third one. Furthermore, a decreased use of macrolides has been observed: 2,825 (20.7%) in the first year, 1,933 (19.6%) in the second and 1,419 (14.3%) in the last one.Conclusions: the use of amoxicillin/clavulanic acid and macrolides is significantly above from what could be expected considering the low prevalence of carriers of Streptococcus pyogenes in the pharynx or of children allergic to penicillin.

[New effects of a topical antimicrobial (agent) in the treatment of acute tonsillopharyngitis]. / Novye effekty topicheskogo antimikrobnogo preparata v lechenii ostrogo tonzillofaringita.

Sore throat is the leading symptom of acute tonsillopharyngitis associated with previous acute respiratory viral infections, including COVID-19. The pathogenesis of these nosologies is based on the cumulative result of the primary direct damaging effect of viruses and secondary alternative inflammatory changes in the mucosal epithelium in the focus of infection, which, against the background of changes in the functions of the regional microbiota, leads to the development of viral-bacterial inflammation that goes beyond the protective-reparative level. In the treatment of acute tonsillopharyngitis after exclusion of GABHS etiology, topical etiotropic drugs are often used. It is desirable to achieve a uniform distribution of active ingredients, and to maximize the use of additional pharmacological capabilities (irrigation-eliminative action, reparative effect). To build up the evidence base for the effectiveness of just such medicines on the basis of the Department of Otorhinolaryngology of the Moscow State Medical University named after. A.I. Evdokimov, an observational prospective comparative study was conducted, using, in addition to the clinical assessment method, cytomorphological approaches (cytomorphometry). The results of the study demonstrated that gargling with a solution of hydroxymethylquinoxylindioxide (Dioxydin 0.25 mg/ml solution for topical application) in adult patients with acute tonsillopharyngitis provides rapid relief of pain, a decrease in the severity of inflammation symptoms, and also makes it possible to achieve limitation of the degree of destruction of the epithelium in the height of inflammation and a more complete and rapid recovery of the damaged mucous membrane by the time of recovery.

Effect of prophylactic amoxicillin on tonsillar bacterial pathogens after (adeno)tonsillectomy in children.

OBJECTIVES: Unnecessary and inappropriate antibiotic use is an increasing global health challenge. In limited resource settings, prophylactic antibiotics are still often used in (adeno)tonsillectomy (AT), despite evidence against their effectiveness. This study aimed to investigate the effect of prophylactic amoxicillin, given after AT in children. METHODS: This is a secondary analysis from a two-center, double-blinded, randomized controlled, non-inferiority trial to study the effect of prophylactic amoxicillin on post-AT morbidity. Children aged 2-14 years with recurrent chronic tonsillitis and/or obstructive sleep apnea were randomly assigned to receive either placebo or amoxicillin for 5 days after the operation. Pre- and postoperative samples were collected for polymerase chain reaction (PCR) analyses to detect the five most important pathogens known to be common causes of tonsillitis. PCR results were compared before and after surgery as well as between placebo and amoxicillin. RESULTS: PCR results were obtained, 109 in the amoxicillin group and 115 in the placebo group. In the amoxicillin group, 91% of patients had at least one positive PCR test before surgery and 87% after surgery. In the placebo group, the respective percentages were 92% and 90%. In both groups, a decrease in the total number of pathogens was found after surgery. CONCLUSION: Prophylactic amoxicillin given after AT in children did not show a clinically relevant effect with respect to the number of oropharyngeal microorganisms as compared to placebo.

Complementary and alternative medicine in the (symptomatic) treatment of acute tonsillitis in children: A systematic review.

BACKGROUND: Acute tonsillitis (including tonsillopharyngitis) in childhood is a common disease with a peak of illness in school-age. Most of these cases have a viral origin and antibiotic therapy is not indicated, therefore, effective symptomatic therapy is required. For this reason, complementary, alternative and integrative medicine therapies might be a solution. OBJECTIVE: The aim of this review is to demonstrate study status of such therapies. METHODS: The databases PubMed, Cochrane Library, OVID, CAMbase, CAM-QUEST® and Anthromedics were systematically screened for studies investigating complementary, alternative and integrative therapy approaches in paediatric cohorts. Studies were analyzed by therapy approach, study design, cohort and outcome, using the PRISMA 2020 checklist. RESULTS: The systematic literature search resulted in 321 articles. Five publications corresponded to the search criteria and were assigned to the following specific therapeutic categories: herbal medicine (3), homeopathy (1) and ayurvedic medicine (1). Clinical trials were found for the herbal compounds BNO 1030 (Impupret®) and EPs® 7630 (Umckaloabo), the homeopathic complex Tonzolyt® and the ayurvedic medicine Kanchnara-Guggulu and Pratisarana of Tankana­Madhu. Antimicrobial effects of essential oils and carvacrol as single agents as well as in combination with erythromycin were analysed in an in vitro study. CONCLUSION: Clinical studies indicate an improvement of symptoms and a good tolerability of all investigated remedies of complementary, alternative and integrative medicine in the treatment of tonsillitis in childhood. Nevertheless, quality and quantity of the studies were insufficient to make a reliable conclusion regarding effectiveness. Therefore, more clinical trials are urgently needed to achieve a meaningful result.

Estudio aleatorizado, doble ciego, sobre la eficacia del tratamiento homeopático en niños con amigdalitis recurrente / Randomized, double-blind study on the efficacy of homeopathic treatment in children with recurrent tonsillitis

La eficacia y seguridad del tratamiento homeopático fueron investigadas en niños con amigdalitis recurrente para la que se indicaba cirugía. Métodos: Estudio clínico prospectivo, aleatorizado, doble ciego, que incluyó 40 niños de entre 3 y 7 años de edad; 20 niños fueron tratados con medicación homeopática y otros 20 niños, con placebo. El seguimiento fue de 4 meses por niño. La evaluación de los resultados fue clínica mediante un cuestionario estándar y examen clínico el primer y último día de tratamiento. La amigdalitis recurrente se definió como ocurrencia de 5 a 7 episodios de amigdalitis bacteriana aguda al año. Resultados: Del grupo de 18 niños que completó el tratamiento homeopático, 14 no presentó episodio alguno de amigdalitis bacteriana aguda; del grupo de 15 niños que recibió placebo, 5 pacientes no presentaron amigdalitis. Esta diferencia fue estadísticamente significativa (p = 0,015). Ninguno de los pacientes presentó efectos secundarios. Conclusiones: El tratamiento homeopático fue efectivo en niños con amigdalitis recurrente, en comparación con el placebo; a 14 niños (78%) ya no se les indicó cirugía. El tratamiento homeopático no se asoció con eventos adversos.

The efficacy and safety of homeopathic treatment was investigated on children with recurrent tonsillitis justifying surgery. Methods: Prospective, randomized,double-blind clinical trial that included 40 children between ages of 3 to 7 years old;20 children were treated with homeopathic medication and 20 children with placebo. Follow up was 4 months per child. Assessment of results was clinical by means of a standard questionnaire and clinical examination on the first and last day of treatment.Recurrent tonsillitis was defined as 5 to 7 episodes of bacterial acute tonsillitis per year. Results: From the group of 18 children who completed homeopathic treatment, 14 did not present any episode of acute bacterial tonsillitis; from the group of 15 children whoreceived placebo 5 patients did not present tonsillitis; this difference was statistically significant (p= 0,015). None of the patient exhibited side effects. Conclusions: Homeopathic treatment was effective in children with recurrent tonsillitis compared to placebo, 14 children (78%) were no longer indicated surgery. Homeopathic treatment was not associated with adverse events.

The Effect of Amoxicillin with Clavulanate on the Microbiota of Tonsillar Tissue in Disease: a Randomized Control Trial.

Despite antibiotics being the primary medical treatment for recurrent tonsillitis, the impact of antibiotics on the tonsillar microbiome is not well understood. This study aimed to determine the effect of amoxicillin with clavulanate on the composition and quantity of bacteria in the tonsils of children with recurrent tonsillitis. A multicenter randomized clinical trial in Auckland, New Zealand was undertaken between August 1, 2017, and June 30, 2018. Sixty children undergoing tonsillectomy for the indication of recurrent tonsillitis were recruited for this study. Following random allocation, 30 participants were prescribed amoxicillin with clavulanate for the week before surgery. The remaining 30 received no antibiotics. Immediately following surgery, the crypts of the right and left tonsils were swabbed. Bacterial 16S rRNA gene-targeted amplicon sequencing and histological techniques were utilized. In the control group, there were significantly higher relative abundances of Haemophilus, Streptococcus, Neisseria, and Porphyromonas. Members from the genera Fusobacterium and Treponema were found to be significantly more abundant in the antibiotic group. There were no significant differences in the absolute quantities of bacteria between the groups. Microscopic examination found fewer bacterial microcolonies present in the tonsillar crypts of participants in the antibiotic group. Streptococcus pyogenes was not present in these bacterial microcolonies. These results suggest that a single course of antibiotics has a significant impact on the tonsil microbiota composition. The duration of this effect and the effect that the altered microbiome has on the course of the condition need to be determined. IMPORTANCE Several studies have identified the presence of multiple pathogenic bacteria in hyperplastic adenoids and palatine tonsils. However, there are currently no studies that utilize this technology to investigate the effect of oral antibiotics in children with recurrent tonsillitis on the tonsillar microbiome. This is the first study to investigate the effect of antibiotics on the microbiome of tonsillar tissue in children with recurrent tonsillitis using molecular techniques. This study has shown that participants who received amoxicillin with clavulanate immediately before tonsillectomy had a significantly reduced number of bacterial taxa commonly associated with recurrent tonsillitis, as well as the number of bacterial microcolonies observed in the tonsillar crypts. This novel finding suggests that either the effect of antibiotics is not sustained or that they are not an effective treatment for recurrent tonsillitis.

[Results of the clinical study of the combination of flurbiprofen and cetylpyridinium chloride in patients with sore throat]. / Rezul'taty klinicheskogo issledovaniya kombinatsii flurbiprofena i tsetilpiridiniya khlorida u patsientov s bol'yu v gorle.

Sore throat is one of the most frequent complaints with which patients seek medical help from an otorhinolaryngologist, therapist and pediatrician. OBJECTIVE: To evaluate the efficacy and safety of a combined topical drug with flurbiprofen and cetylpyridinium chloride compared with a monocomponent drug in patients with sore throat associated with manifestations of acute pharyngitis, tonsillitis or with exacerbation of chronic forms of pharyngitis or tonsillitis. MATERIAL AND METHODS: A prospective, multicenter, open, randomized, comparative study in parallel groups included 266 adult patients aged 18 to 60 years with an established diagnosis of acute pharyngitis or acute tonsillitis with the main complaint of sore throat caused by viral infections of the upper respiratory tract. The patients included in the study were randomized into two groups of 133 participants each: the 1st group included patients who received the combined agent flurbiprofen 8.75 mg and cetylpyridinium chloride 1.0 mg in the form of tablets for resorption; the 2nd group included patients who received cetylpyridinium chloride 1.2 mg in the form of medicinal lozenges. The effectiveness was evaluated on three scales - STPIS, TPA, STPR, reflecting indicators of the dynamics of the disease. RESULTS: The studied combination turned out to be more effective than the monocomponent remedy and was characterized by a more pronounced decrease in the intensity of sore throat within 2 hours after taking the drug and a decrease in pharyngeal hyperemia. CONCLUSION: According to results of the study, the use of a drug based on the combination of flurbiprofen and cetylpyridinium chloride was accompanied by a rapid and pronounced decrease in the intensity of sore throat and pharyngeal hyperemia in patients with upper respiratory tract infections.

Clinical course of pharyngotonsillitis with group A streptococcus treated with different penicillin V strategies, divided in groups of Centor Score 3 and 4: a prospective study in primary care.

BACKGROUND: Sore throat is a common reason for prescribing antibiotics in primary care, and 10 days of treatment is recommended for patients with pharyngotonsillitis with group A streptococcus (GAS). Our group recently showed that penicillin V (PcV) four times daily for 5 days was non-inferior in clinical outcome to PcV three times daily for 10 days. This study compares duration, intensity of symptoms, and side effects in patients with a Centor Score (CS) of 3 or 4 respectively, after treatment with PcV for 5 or 10 days and evaluates whether all patients with pharyngotonsillitis with a CS of 3 or 4 should be treated for 5 days or if severity of symptoms or CS suggest a longer treatment period. METHOD: Data on symptoms and recovery from patient diaries from 433 patients included in a RCT comparing PcV 800 mg × 4 for 5 days or PcV 1 g × 3 for 10 days was used. Patients six years and older with CS-3 or CS-4 and positive rapid antigen detection test for GAS-infection were grouped based on CS and randomized treatment. Comparisons for categorical variables were made with Pearson's chi-squared test or Fisher's exact test. Continuous variables were compared with the Mann-Whitney U test. RESULTS: Patients with CS-3 as well as patients with CS-4 who received PcV 800 mg × 4 for 5 days self-reported that they recovered earlier compared to patients with CS-3 or CS-4 who received treatment with PcV 1 g × 3 for 10 days. In addition, the throat pain as single symptom was relieved 1 day earlier in patients with CS-4 and 5 days of treatment compared to patients with CS-4 and 10 days of treatment. No differences in side effects between the groups were found. CONCLUSION: Intense treatment with PcV four times a day for 5 days seems clinically beneficial and strengthens the suggestion that the 4-dose regimen with 800 mg PcV for 5 days may be the future treatment strategy for GAS positive pharyngotonsillitis irrespectively of CS-3 or CS-4. Trail registration ClinicalTrials.gov ID: NCT02712307 (3 April 2016).

Monkeypox in a Patient with Controlled HIV Infection Initially Presenting with Fever, Painful Pharyngitis, and Tonsillitis.

Background and Objectives: With more and more cases emerging outside central and west African countries, where the disease is endemic, the World Health Organization (WHO) has recently declared human monkeypox a Public Health Emergency of International Concern. Typical symptoms of the disease include fever, myalgia, and lymphadenopathy followed by a rash, but other symptoms may occur. Immunocompromised patients, including patients with uncontrolled Human Immunodeficiency Virus (HIV) infection, may be at risk for more severe courses. Case presentation: We present the case of a 30-year-old male patient of Brazilian descent with monkeypox. Initial symptoms were fever and general discomfort, with painful pharyngitis and tonsillitis and finally a papular rash of the anogenital area as the disease progressed. The presumed date of infection was a sexual contact with an unknown male eight days before the first symptoms occurred. The patient had a known and controlled HIV infection. The main reason for the initial presentation at the hospital was painful pharyngitis and tonsillitis, limiting food intake. Monkeypox infection was confirmed via PCR testing from a swab sample of cutaneous lesions. Adequate systemic and local analgesia enabled oral food uptake again. Antiviral therapy with Tecovirimat was not administered due to the stable immune status of the patient and the mild clinical symptoms. To cover a possible bacterial superinfection or Syphilis infection of the tonsil, antibiotic therapy with Ceftriaxone was added. Several days after presentation, the inflammation of the pharynx resolved and was followed by non-painful mucosal peeling. The patient was followed up with telephone calls and reported a complete recovery. The skin lesions were completely dried out 18 days after the first symptoms. Conclusions: Painful pharyngitis and tonsillitis can be rare early symptoms of monkeypox, which is highly relevant in everyday clinical practice. Particularly in patients with risk factors for monkeypox infection, further clinical and microbiologic testing for monkeypox should be performed if there is a clinical presentation with pharyngitis and tonsillitis.

Retrospective study on the effectiveness and safety of the shortened 5- to 7-day antibiotic regimen for acute streptococcal pharyngotonsillitis compared to the classic 10-day regimen.

INTRODUCTION: Antibiotherapy regimens for management of acute streptococcal pharyngitis traditionally last 10 days, but the development of resistance to different antimicrobials has motivated the exploration of shorter courses. MATERIAL AND METHODS: We selected patients given a diagnosis of streptococcal pharyngitis in 2 paediatric caseloads of 1 primary care centre between June 2016 and April 2020. We compared outcomes in patients treated with 8- to 10-day courses versus 5- to 7-day courses. RESULTS: The analysis included 350 care episodes (252 patients). Sixty-four percent were managed with 8- to 10-day courses of antibiotherapy (group 1) and 36% with 5- to 7-day courses (group 2). There were no significant differences in the incidence of streptococcal pharyngitis or scarlet fever in the 3 months that followed (OR, 0.98; 95% confidence interval [CI], 0.46-2.03), with similar percentages in both groups (9.8% vs 9.5%). Overall, without differentiating based on the type of infection (streptococcal pharyngitis, scarlet fever or other streptococcal infections), we found similar outcomes (OR, 0.81; 95% CI, 0.41-1.59): 13.4% in group 1 and 11.1% in group 2. We also found no differences in the frequency of adverse events documented in the health records (OR, 0.29; 95% CI, 0.04-2.44): 2.7% in group 1 and 0.8% in group 2. CONCLUSIONS: In our experience, a shorter antibiotic course (5-7 days) is not less effective or more unsafe for management of acute streptococcal pharyngitis than the traditional 10-day course.

Analysis of Microorganism Colonization, Biofilm Production, and Antibacterial Susceptibility in Recurrent Tonsillitis and Peritonsillar Abscess Patients.

Background: Despite the widespread use of antibiotics to treat infected tonsils, episodes of tonsillitis tend to recur and turn into recurrent tonsillitis (RT) or are complicated by peritonsillar abscesses (PTAs). The treatment of RT and PTAs remains surgical, and tonsillectomies are still relevant. Materials and methods: In a prospective, controlled study, we analyzed the bacteria of the tonsillar crypts of 99 patients with RT and 29 patients with a PTA. We performed the biofilm formation and antibacterial susceptibility testing of strains isolated from study patients. We compared the results obtained between patient groups with the aim to identify any differences that may contribute to ongoing symptoms of RT or that may play a role in developing PTAs. Results: The greatest diversity of microorganisms was found in patients with RT. Gram-positive bacteria were predominant in both groups. Candida species were predominant in patients with a PTA (48.3% of cases). Irrespective of patient group, the most commonly isolated pathogenic bacterium was S. aureus (in 33.3% of RT cases and in 24.14% of PTA cases). The most prevalent Gram-negative bacterium was K. pneumoniae (in 10.1% of RT cases and in 13.4% of PTA cases). At least one biofilm-producing strain was found in 37.4% of RT cases and in 27.6% of PTA cases. Moderate or strong biofilm producers were detected in 16 out of 37 cases of RT and in 2 out of 8 PTA cases. There was a statistically significant association found between the presence of Gram-positive bacteria and a biofilm-formation phenotype in the RT group and PTA group (Pearson χ2 test, p < 0.001). S. aureus and K. pneumoniae strains were sensitive to commonly used antibiotics. One S. aureus isolate was identified as MRSA. Conclusions: S. aureus is the most common pathogen isolated from patients with RT, and Candida spp. are the most common pathogens isolated from patients with a PTA. S. aureus isolates are susceptible to most antibiotics. Patients with RT more commonly have biofilm-producing strains, but patients with a PTA more commonly have biofilm non-producer strains. K. pneumoniae does not play a major role in biofilm production.
