Abstract:

Acute tonsillopharyngitis is one of the most frequent reasons for visiting a doctor and prescribing inappropriate antibiotic therapy (ABT). There are several reasons for this — from the difficulties of etiological diagnosis and the development of relapses and possible severe complications to the personal attitude of doctors and patients to the choice of treatment. At the same time, the issue of antibiotic resistance and other aspects associated with the prescription of ABT is one of the most important problems of modern healthcare worldwide. The purpose of this review is to demonstrate the best practical approaches to the choice of treatment tactics for acute tonsillitis (AT) in the treatment of children and adults, with an emphasis on reducing the load of ABT. The review examines the indications and disadvantages of clinical and laboratory diagnosis of AT. There are no highly sensitive clinical and laboratory instruments that differentiate viral and bacterial AT. Exudativeis AT in children is not an underlying symptom of streptococcal etiology. Despite the limitations, the modified Centor/McIsaac score ≥3 (taking into account age and the presence of respiratory symptoms) should be used as an indication for ABT in conjunction with a rapid streptotest and subsequent bacteriological culture for S. pyogenes if the screening test is negative. Additional examinations (determination of leukocytosis, CRP and procalcitonin test) are not required for most patients. ABT should not be given to low-risk patients for the treatment and prevention of rheumatic fever and acute glomerulonephritis. Prevention of purulent complications (paratonsillitis and retropharyngeal abscess, acute otitis media, cervical lymphadenitis, mastoiditis, or acute sinusitis) is not a specific indication for ABT in AT and is not required in most patients. The strategy of «delayed antibiotic prescriptions» with monitoring the patient’s condition for 2—3 days is appropriate and highly effective in doubtful cases. The drugs of choice for treatment of AT are amoxicillin and oral forms of I and II generation cephalosporins. Macrolides are not indicated as first-line treatment for AT. The course of ABT for streptococcal AT is 10 days, which reduces the risk of recurrent episode. Topical drugs can be the only means of etiopathogenetic treatment with viral AT, or additional for bacterial AT. Their use not only relieves sore throat, but also shortens the duration of the disease, and also improves the patients prognosis. Benzalkonium chloride + tyrothricin + benzocaine (Dorithyrcin) may be a rational drug of choice for topical therapy due to the available clinical evidence. There is a significant reserve for reducing the load of ABT during AT. Further clinical trials are needed to assess the efficacy of short courses of ABT in the treatment of AT in high-income countries and provide a basis for strong recommendations for topical drug use. This can reduce the frequency of ABT prescribing and increase the level of interaction between specialists and patients.
