ABSTRACT

PURPOSE: Recurrent tonsillitis in children is a common disease affecting children quality of life and extends to their families. The aim of this study was to assess the effect of combined use of oral Azithromycin (AZT) plus Echinacea compared to exclusive use of AZT in children with recurrent tonsillitis. MATERIAL AND METHODS: A prospective comparative study including three groups of children with recurrent tonsillitis. Group 1: (100 patients) had no prophylactic treatment. Group 2 (100 patients) received [60 mg/kg] prophylactic dose of AZT divided as (10 mg/kg/day) over 6 consecutive days every month for 6 consecutive months. Group 3 (100 patients) received AZT as in group 2 plus commercially available Echinacea in a dose of 5 ml oral suspension; 3 times daily for 10 consecutive days every month for 6 consecutive months. Number of tonsillitis attacks and severity of tonsillitis symptoms were assessed and compared in different groups. RESULTS: Group 2 and group 3 had significant less number of tonsillitis attacks and severity of assessed symptoms during 6 months of prophylactic treatment with significant better results in group 3 (i.e. AZT plus Echinacea) compared to group 2 (I.e. AZT alone). However; there was no significant difference in patients with any prophylaxis. CONCLUSION: The combined use of Echinacea with Azithromycin produced favorable outcome than Azithromycin alone in pediatric patients with recurrent tonsillitis.

ABSTRACT

Chronic tonsillitis is one of the most common diseases to modern people, which treatment requires a preventative care course approach. The general purpose of the present research could be framed as follows: to estimate clinical efficiency of bacteriophage medications, in the case of 'Ostophag' mixture for preventative care. Study population consisted eighty people. Participants were divided into two groups (forty patients in each) both diagnosed compensated and decompensated forms of chronic tonsillitis with pathogenic microflora in the lacunae of the palatine tonsils. In the first group we built monotherapy on bacteriophage medications use, whereas in the second one monotherapy was founded on antiseptic implication. The results of the present investigation showed high efficiency of bacteriophage medications a means of chronic tonsillitis salvage care.

ABSTRACT

The purpose was to determine the current evidence for preferable antibiotic treatment in three common clinical situations with insufficient consensus: Q1: Can antibiotic treatment prevent future attacks of acute pharyngo-tonsillitis (APT) in patients with recurrent APT (RAPT)? Q2: Which antibiotic regimen is preferable in the treatment of APT in patients with RAPT? Q3: Which antibiotic regimen is preferable in the treatment of relapsing APT? Five databases were searched systematically for randomized clinical trials on patients with RAPT with or without current APT or with relapse of APT. Of the unique publications, 643 were found. Five studies addressing Q1 (n = 3) and Q2 (n = 2) met the eligibility criteria. No studies reporting on Q3 were included. Q1: Two studies found that clindamycin and cefpodoxime, respectively, were effective in preventing future APT episodes and in eradicating group A streptococci from the tonsils of RAPT patients. One study found that long-term azithromycin had no effect on the number of APT episodes. Q2: Two studies reported superior clinical and microbiological effects of clindamycin and amoxicillin with clavulanate, respectively, compared to penicillin. The four studies showing superior effects of clindamycin and amoxicillin with clavulanate were assessed to have high risk of bias. Hence, the level of evidence was moderate. There is considerable evidence to suggest that clindamycin and amoxicillin with clavulanate are superior to penicillin with preferable effects on the microbiological flora and the number of future attacks of APT in patients with RAPT. Antibiotic treatment is an option in patients with RAPT, who has contraindications for tonsillectomy.

ABSTRACT

BACKGROUND: Previous trials, performed in subjects affected by recurrent streptococcal pharyngo-tonsillar infection, have shown that the use for 90 days of Streptococcus salivarius K12 (K12), an oral colonizing probiotic producing lantibiotic bacteriocins, reduces the occurrence of streptococcal and viral pharyngitis and acute otitis media (AOM). The aim was to evaluate the role of K12 in reducing the incidence of streptococcal and viral pharyngo-tonsillitis and AOM when administered in two separate trimesters, from October to December and then from April to June, in pediatric subjects with non-recurrent streptococcal infection. METHODS: We retrospectively analyzed the incidence of pharyngo-tonsillitis and AOM in 133 children by comparing the number of episodes occurring between September 1st, 2014 and August 31st, 2015, when no treatment with K12 was given, with the period between September 1st, 2015 and August 31st, 2016, when K12 was administered. RESULTS: Analysis of the findings for the 133 children demonstrated that K12 use decreased the incidence of pharyngo-tonsillitis by about 90% (P<0.001) and the occurrence of AOM by about 70% (P<0.001) and confirms the high safety profile of the strain. CONCLUSIONS: As already demonstrated in subjects with recurrent streptococcal pharyngo-tonsillar infection, K12, if administered for two trimesters out of 12 months, is associated with a reduced incidence of pharyngitis and AOM in pediatric subjects with non-recurrent streptococcal infection.

ABSTRACT

A 23-year-old woman with preexisting Graves' disease who received thiamazole treatment presented with fever, dysphagia, hyperthyroidism and leukopenia. With suspicion of thyreotoxicosis accompanied by drug-induced agranulocytosis she was successfully managed by plasmapheresis, G­CSF administration and inhibition of periphereal conversion of thyroid hormones. In due course she underwent thyroidectomy. Thiamazole is frequently associated with drug-induced agranulocytosis. Long-term therapy with thiamazole requires critical evaluation and alternatives should be considered early. Plasmapheresis is an adequate treatment option to achieve normal thyroid hormonal status.

ABSTRACT

Currently Staphylococcus aureus is the predominant pathogen isolated from the respiratory tract of patients with recurrent tonsillitis. Because of an increase in multi-drug resistant strains of S. aureus, there is a pressing need for effective treatments and preventive approaches to reduce the risk of invasive and life-threatening infections. A preventive vaccine against S. aureus would have a tremendous clinical impact. However, multiple clinical trials have failed to identify an agent that can induce protective responses. Most trials have been based on subunit vaccines using one or a few purified antigens, which may not be enough to confer protection. Here, the impact of a whole-cell vaccine comprised of heat-inactivated S. aureus was investigated in patients with RT. The vaccine was well tolerated and had no significant local or systemic reactions. Immunization with heat-inactivated S. aureus elicited a significant antibody response characterized by production of IgG1 and IgG2 antibodies and, to a lesser extent, of IgA antibodies. Notably, this response was associated with an important decrease in the incidence of tonsillitis and bacterial colonization of the oropharyngeal mucosa. Our results show that whole-cell inactivated S. aureus is safe and capable of evoking specific antibody responses in patients with recurrent tonsillitis.

ABSTRACT

This study was undertaken with the purpose of improving the effectiveness of the preventive treatment of chronic adenoiditis in the children. The open randomized comparative study included 219 children aged from 6 to 7 years presenting with clinical and anamnestic signs of chronic adenoiditis. The study group was comprised of 113 patients given the Streptococcus salivarius K12-based probiotic complex during 30 days in combination with the nasal-douche. The control group consisted of 106 patients treated with the nasal douche alone. The analysis of the results of the study has demonstrated that episodes of exacerbation of adenoiditis on day 30 after the onset of the treatment occurred in 56 (49.6%) children of the study group compared with 95 (88.7%) patients of the control group. Three months later, acute sinusitis was diagnosed in 4 (3.5%) children of the study group compared with 14 (13.2%) ones in the control group. Acute otitis media was documented in 2 (1.8%) and 5 (4.7%) children of the study and control groups respectively. It is concluded that the treatment with the use of the Streptococcus salivarius K12-based probiotic complex permits to decrease the frequency of exacerbations of chronic adenoiditis and its complications in the children and reduces the requirement for medication therapy.

ABSTRACT

BACKGROUND: Measles is the leading killer among vaccine-preventable diseases; it is responsible for an estimated 44% of the 1.7 million vaccine-preventable deaths among children annually. OBJECTIVES: To assess the effects of antibiotics given to children with measles to prevent complications and reduce pneumonia, other morbidities and mortality. SEARCH METHODS: We searched CENTRAL 2013, Issue 4, MEDLINE (1966 to May week 4, 2013) and EMBASE (1980 to May 2013). SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs comparing antibiotics with placebo or no treatment, to prevent complications in children with measles. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality. MAIN RESULTS: Seven trials with 1263 children were included. The methodological quality of most studies was poor. Only two studies were randomized, double-blind trials. There was variation in antibiotics used, their doses, schedule and evaluation of outcome. Pooled study data showed that the incidence of pneumonia was lower in the treatment group compared to the control group. However, the difference was not statistically significant. Of the 654 children who received antibiotics, 27 (4.1%) developed pneumonia; while out of 609 children in the control group, 59 (9.6%) developed pneumonia (odds ratio (OR) 0.35; 95% confidence interval (0.12 to 1.01). The one trial that showed an increase in the rate of pneumonia with antibiotics was conducted in 1942 and compared oral sulfathiazole with symptomatic treatment. If the results of this trial are removed from the meta-analysis, there is a statistically significant reduction in the incidence of pneumonia in children receiving antibiotics (OR 0.26; 95% CI 0.12 to 0.60). The incidence of other complications was significantly lower in children receiving antibiotics: purulent otitis media (OR 0.34; 95% CI 0.16 to 0.73) and tonsillitis (OR 0.08; 95% CI 0.01 to 0.72). There was no difference in the incidence of conjunctivitis (OR 0.39; 95% CI 0.15 to 1.0), diarrhea (OR 0.53; 95% CI 0.23 to 1.22) or croup (OR 0.16; 95% CI 0.01 to 4.06). No major adverse effects attributable to antibiotics were reported. AUTHORS' CONCLUSIONS: The studies reviewed were of poor quality and used older antibiotics. This review suggests a beneficial effect of antibiotics in preventing complications such as pneumonia, purulent otitis media and tonsillitis in children with measles. On the basis of this review, it is not possible to recommend definitive guidelines on the type of antibiotic, duration or the day of initiation. There is a need for more evidence from high-quality RCTs to answer these questions.

ABSTRACT

OBJECTIVE: A food-borne tonsillopharyngitis outbreak was reported between 9th and 13th of February, 2008, in Söke State Hospital, Aydin, Turkey. METHODS: This descriptive cohort study was carried out immediately after the outbreak. In order to determine the probable origin, a questionnaire involving demographical features, clinical features, and possible risk factors was distributed to 403 persons. The participants of the questionnaire (n = 403) were divided into two groups: the study group (n = 252); those with any two of the following three complaints; sore throat, fever, and dizziness, and the control group (n = 151); those without these complaints. RESULTS: This investigation revealed that 252 people were affected by this outbreak. Group A ß-hemolytic streptococci were isolated from the throat cultures of 63 affected individuals (25%) and an employee working in the patisserie that made desserts served for lunch. Since the number of people who ate the milky dessert was statistically higher compared to the non-eaters, the milky dessert was thought to be the origin of the outbreak. CONCLUSIONS: We suggest that throat infections among employees working in food production may cause outbreaks of upper respiratory tract infections.

ABSTRACT

The present clinical study had the objective to evaluate the role of a hypertonic solution of sterile water from the Adriatic Sea in the prevention and treatment of chronic adenoiditis in children. It included 30 children aged from 2.5 to 15 years. The control group was comprised of 30 children treated by intransal drop infusion of physiological saline followed by irrigation of the nasal cavity with framicetin as recommended by the manufacturer. The study failed to reveal a significant difference (P > 0.05) between dynamics of the symptoms of chronic adenoiditis in the patients of either group assessed based on the 10-point analog visual scale. However, the frequency of relapses of adenoiditis during the observation period (3 months) was significantly lower in the patients treated with the hypertonic solution of sterile seawater. Microbiological investigations of the material from the pharyngonasal cavity showed no difference between the occurrence of tansient bacterial microflora in the patients of the study and control groups.

ABSTRACT

The morbidity of tonsillitis in military drafting personnel of internal troops of Ministry of the Interior of Russia was high and had the up trend during 2000-2007. In 2008-2009 took place new increase of these diseases. The most unfortunate was the Second training center. Overcrowded accommodation of cadets in kasernes and complete rotation 2 times per year promoted this increase. The conditions of accommodation of cadets ware improved in 2010, preventive prophylaxis of tonsillitis was provided with the help of Bitsillin-5. As a result, the amount of ill in the Second training center during the summer 2010 was 5, 6 times lower than in the same period of 2009. It shows that the best antiepidemic effect can be achieved with combination of measures against the carry-over of causative agent and medicated prophylaxis.

ABSTRACT

Oral supplements (OS) support the immune system in fighting upper airways infection. This study aimed to analyze the effect of Difensil Immuno (DI) on the recurrence of tonsillitis and fever in children. A multicentric randomized clinical trial was conducted. One-hundred and twenty children with chronic tonsillitis were randomly assigned to group A, B or control. Patients in group A were treated with 10 mL of DI for 90 consecutive days, patients in group B underwent treatment with 15 mL of DI for 45 consecutive days. The following data were collected at baseline (T0), T1 and T2: tonsillitis and fever episodes, tonsillar volume, blood test results. One-way ANOVA was used to analyze within and between variances. Patients in group A and B statistically improved their clinical parameters (episode of tonsillitis and fever, tonsillar volume) when compared to control group both at T1 and T2. However, T1 variances were more consistent in group A than in group B. All patients in the study groups improved their clinical outcomes. No statistically significant variances were observed in blood parameters both at T1 and T2. Our results suggest that children treated with DI had fewer episodes of tonsillitis and fever and a reduction in their tonsillar volume.

ABSTRACT

OBJECTIVES: The coronavirus outbreak has triggered the implementation of nationwide social distancing measures. We aimed to investigate the impact on patients with recurrent tonsillitis and parental perceptions towards tonsillectomy during the COVID-19 pandemic. METHODS: A telephone questionnaire was conducted for all children awaiting tonsillectomy for recurrent tonsillitis after social distancing for 2 months at our centre. The COVID-19 lockdown period was compared with the 2 months prior to lockdown. RESULTS: Forty-four children had been social distancing at home during lockdown. There was a significant reduction in tonsillitis episodes during the 2-month lockdown period in comparison with 2 months prior to lockdown (p = 0.0001). In 70% (n = 31) of cases parents wanted their child's tonsillectomy during the coronavirus outbreak. CONCLUSION: These findings demonstrate that viral exposure is a key factor in the pathophysiology of recurrent tonsillitis and that social distancing measures can reduce the frequency of recurrent tonsillitis. Despite the overall reduction in tonsillitis frequency during the lockdown period, the majority of parents wanted their child's tonsillectomy during the coronavirus outbreak. This demonstrates the impact tonsillitis has on the patient and their family's quality of life.

ABSTRACT

Group A Streptococcus (GAS) infections account for an estimated 500,000 deaths every year. This bacterial pathogen is responsible for a variety of mild and life-threatening infections and the triggering of chronic autoimmune sequelae. Pharyngitis caused by group A Streptococcus (GAS), but not asymptomatic GAS carriage, is a prerequisite for acute rheumatic fever (ARF). Repeated bouts of ARF may trigger rheumatic heart disease (RHD), a major cause of heart failure and stroke accounting for 275,000 deaths annually. A vaccine that prevents pharyngitis would markedly reduce morbidity and mortality from ARF and RHD. Nonhuman primates (NHPs) have been utilized to model GAS diseases, and experimentally infected rhesus macaques develop pharyngitis. Here we use an NHP model of GAS pharyngitis to evaluate the efficacy of an experimental vaccine, Combo5 (arginine deiminase [ADI], C5a peptidase [SCPA], streptolysin O [SLO], interleukin-8 [IL-8] protease [SpyCEP], and trigger factor [TF]), specifically designed to exclude GAS components potentially linked to autoimmune complications. Antibody responses against all Combo5 antigens were detected in NHP serum, and immunized NHPs showed a reduction in pharyngitis and tonsillitis compared to controls. Our work establishes the NHP model as a gold standard for the assessment of GAS vaccines.IMPORTANCE GAS-related diseases disproportionally affect disadvantaged populations (e.g., indigenous populations), and development of a vaccine has been neglected. A recent strong advocacy campaign driven by the World Health Organization and the International Vaccine Institute has highlighted the urgent need for a GAS vaccine. One significant obstacle in GAS vaccine development is the lack of a widely used animal model to assess vaccine efficacy. Researchers in the field use a wide range of murine models of infection and in vitro assays, sometimes yielding conflicting results. Here we present the nonhuman primate pharyngeal infection model as a tool to assess vaccine-induced protection against colonization and clinical symptoms of pharyngitis and tonsillitis. We have tested the efficacy of an experimental vaccine candidate with promising results. We believe that the utilization of this valuable tool by the GAS vaccine research community could significantly accelerate the realization of a safe and effective GAS vaccine for humans.

ABSTRACT

OBJECTIVE: To assess the effectiveness of tonsillectomy/adenotonsillectomy in reducing medical care visits for pharyngitis or tonsillitis in children and adults with chronic/recurrent tonsillitis. DESIGN: Retrospective cohort study. SETTING: Data were retrieved from the VEGA register, a comprehensive regional cohort in Sweden. PARTICIPANTS: 1044 children (<15 years) and 2244 adults. INTERVENTION: Tonsillectomy/adenotonsillectomy compared with no surgical treatment. MAIN OUTCOME MEASURES: Changes in yearly mean rates of medical care visits due to pharyngitis/tonsillitis. RESULTS: In children, there was a significant decrease in the yearly mean medical care visits rate from 1.93 (1.82 to 2.04) before surgery to 0.129 (0.099 to 0.165) after surgery, with a mean change of -1.80 (-1.90 to -1.69), p<0.0001. In patients who did not undergo surgery, the corresponding mean change was -1.51 (-1.61 to -1.41), resulting in a mean difference in the change in visit rates between the intervention and control groups of -0.283 (-0.436 to -0.135), p=0.0002. In adults, a significant decrease in the yearly mean medical care visit rate was observed from 1.45 (1.39 to 1.51) before surgery to 0.152 (0.132 to 0.173) after surgery, with a mean change of -1.30 (-1.36 to -1.24), p<0.0001, compared with -1.18 (-1.24 to -1.13) in the control group. The difference in the change in yearly mean visit rate between the surgical and non-surgical groups was -0.111 (-0.195 to -0.028), p=0.0097. The subgroup analysis showed a greater effect of surgery in children, in patients with a higher number of medical care visits before surgery and in the first year of follow-up. CONCLUSION: In this cohort of patients moderately or less affected with chronic/recurrent tonsillitis, the effectiveness of tonsillectomy/adenotonsillectomy in reducing medical care visits for pharyngitis and tonsillitis compared with no surgical treatment was low and of questionable clinical value.

ABSTRACT

The aim of this study was to verify the frequency of atypical bacterial infections in children undergoing tonsillectomy because of severely recurrent acute tonsillopharyngitis (AT) and the possible benefit of surgery in cases in which Mycoplasma pneumoniae and Chlamydophila pneumoniae seem to play a role in causing the recurrences. A total of 118 patients (76 males; mean age +/- standard deviation, 6.67 +/- 3.31 years) were enrolled: 59 underwent tonsillectomy because of severely recurrent AT and 59 underwent adenotonsillectomy because of obstructive sleep apnea syndrome (OSAS). The results show, for the first time, that the great majority of children with a history of severely recurrent AT (and, therefore, considered to be eligible for elective tonsillectomy) are infected by atypical bacteria, mainly M. pneumoniae, and that tonsillectomy seems to be effective in reducing the recurrence of both AT and acute respiratory disease during 12 months follow-up postsurgery.

ABSTRACT

BACKGROUND: Measles is the leading killer among vaccine-preventable diseases, responsible for an estimated 44% of the 1.7 million vaccine-preventable deaths among children annually. OBJECTIVES: To assess the effects of antibiotics given to children with measles to prevent complications and reduce pneumonia, other morbidities and mortality. SEARCH STRATEGY: In this 2008 update we searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 1) MEDLINE (1966 to January week 1, 2008), EMBASE (1980 to December 2007) and the National Research Register (Issue 3, 2007). SELECTION CRITERIA: Randomized controlled trials (RCTs) and quasi-RCTs comparing antibiotics with placebo or no treatment to prevent complications in children with measles. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality. MAIN RESULTS: Seven trials with 1385 children were included. Pooled study data showed that the incidence of pneumonia was lower in the treatment group compared to the control group. However, the difference was not statistically significant. In children who received antibiotics, 1.9% developed pneumonia, while in the control group 6% developed pneumonia (OR 0.28; 95% CI 0.06 to 1.25). The one trial that showed an increase in the rate of pneumonia with antibiotics was conducted in 1942 and compared oral sulfathiazole with symptomatic treatment. If the results of this trial are removed from the meta-analysis, and the remaining six studies are combined, there is a statistically significant reduction in the incidence of pneumonia in children receiving antibiotics (OR 0.17; 95% CI 0.05 to 0.65). The number needed to treat to prevent one episode of pneumonia is 24 patients. The incidence of other complications was significantly lower in children receiving antibiotics: purulent otitis media (OR 0.34; 95% CI 0.16 to 0.73) and tonsillitis (OR 0.08; 95% CI 0.01 to 0.72). There was no difference in the incidence of conjunctivitis (OR 0.39; 95% CI 0.15 to 1.0), diarrhea (OR 0.53; 95% CI 0.23 to 1.22) or croup (OR 0.16; 95% CI 0.01 to 4.06). AUTHORS' CONCLUSIONS: This review suggests a beneficial effect of antibiotics in preventing complications such as pneumonia, purulent otitis media and tonsillitis in children with measles. On the basis of this review, it is not possible to give definitive guidelines on the type of antibiotic, duration, or the day of initiation. Use of penicillin or co-trimoxazole may be considered. There is a need to generate more evidence by well planned RCTs to answer these questions.

ABSTRACT

OBJECTIVE: Although much has been written on how to manage recurrent pharyngotonsillitis, it remains a controversial topic. The composition of normal commensal oropharynx bacteria may be disrupted by frequently using antimicrobials, by inhibiting sensitive organisms and by allowing resistant organisms to overgrowth. This may cause the recurrence of acute episodes. The aim of this study was to evaluate the efficacy of ribosomal immunotherapy in the prophylaxis of recurrent pharyngotonsillitis. METHODS: A total of 160 children aged between 5 and 14 years with recurrent pharyngotonsillitis were ramdomized to receive either ribosomal immunotherapy (group A one tablet a day, 8 days a month for 3 months) or a placebo (group B same dosage for the same period). RESULTS: At the end of the study, each patient treated with Immucytal presented a subjective decrease of symptoms. Compared with group B, group A experienced a significant improvement of some clinical parameters. CONCLUSIONS: The results show that ribosomal immunotherapy causes a significant improvement of both specific and non-specific immunity and may be effective in the prophylaxis of recurrent pharyngotonsillitis and in preventing recurrences without entailing side effects or bacterial resistance.
