Antibacterial therapy for acute infections of the ENT organs

Sore throat, dryness, burning sensation, discomfort and sharp pain when swallowing - each of us has probably encountered these symptoms, regardless of gender and age.

It’s especially disappointing when a sudden sore throat disrupts pre-planned plans and prevents you from leading your usual lifestyle. And then there may be a desire to deal with the disease by starting treatment with antibiotics. But such therapy is indicated only if it is recommended by a doctor; self-medication can be harmful. Let's find out why.

How do antibiotics work?

With the discovery of antibiotics, humanity in the 20th century began to hope, if not for eternal life, then at least for complete relief from all diseases. But that did not happen. After all, antibiotics can only fight bacterial diseases. But they are powerless against viruses.2

This means that for acute respiratory viral infections, influenza, tonsillitis, pharyngitis, laryngitis and other diseases that cause a sore throat, antibiotics may be needed only in a small percentage of cases, and the need to take them can only be determined by a doctor.

Is it true that antibiotics do not cure everything?

- Wait! - you say. – If antibiotics are useless, why are they so often prescribed by doctors for sore throats?

No doctor, without special tests, can determine in 100% of cases whether a sore throat is caused by bacteria or viruses. Therefore, today there is a growing trend of overprescription of antibiotics throughout the world. According to statistics, 80-90% of cases of acute inflammation of the pharynx in adults are caused by a viral infection, and only 10-20% are caused by bacteria.1 The problem is that bacteria have launched a counter-offensive. By mutating, some of them have learned to become resistant to drugs. That is, when a population is exposed to an antibiotic, real natural selection occurs according to the Darwinian model. You can say: “What doesn’t kill bacteria makes them stronger.”

In this way, resistance can develop - the immunity of bacteria to antibiotics. What could this lead to?

Why is antibiotic resistance dangerous?

According to WHO experts, antibiotic resistance is one of the most serious threats to human health, food security and development today.1

And this problem can only be dealt with by refusing to take antibiotics “just in case,” for prevention, or hoping to quickly get rid of unpleasant symptoms. Taking antibiotics for a sore throat in the absence of bacterial diseases, you will not help yourself, but on the contrary, you can harm. Remember: in many cases, symptomatic treatment can help with a sore throat.

Composition of monocomponent drugs for sore throat

What diseases cause a sore throat?

Unpleasant sensations of scratching, rawness, a feeling of a foreign body in the throat, pain when swallowing food - all these symptoms can accompany pharyngitis, tonsillitis and laryngitis. These viral diseases are quite common, they lead to discomfort in the throat and can disrupt many of our plans.

Pharyngitis is an acute or chronic inflammation of the mucous membrane of the pharynx, most often of a viral nature. That is, it makes no sense to treat it with antibiotics; symptomatic treatment would be appropriate. Tonsillitis is an inflammation of the palatine tonsils (they are also called tonsils), and laryngitis is an inflammation of the mucous membrane of the larynx and vocal cords, often of a viral nature. Symptomatic therapy is also successfully used in the treatment of these diseases.

Antibacterial drugs for these diseases are required in 5-15% of cases when the cause of the disease is streptococci.2 To determine the pathogen, a bacteriological examination of a throat smear is necessary, the result of which may take some time, sometimes up to several days. Therefore, for a sore throat, in many cases, the doctor may recommend symptomatic local therapy that helps combat the discomfort.

ANTIBACTERIAL THERAPY OF INFECTIONS IN OTORHINOLARYNGOLOGY

L.S. Strachunsky, E.I. Kamanin

"Russian Medical Journal", 1998; vol.6, no.11, pp.684-693

Epidemiology

In the available literature, we did not find modern data on the prevalence of ENT infections in Russia. To get an idea of ​​their prevalence, we extrapolated data obtained in the United States and Western Europe [1]. Based on data from foreign colleagues, we can assume that every year in Russia 10 million people suffer from acute sinusitis that developed in a community setting.

According to foreign sources, acute otitis media (AOM) is the most common bacterial infection in children. To compare these data with domestic ones, we studied 400 randomly selected outpatient records of children in the first 5 years of life. It turned out that if, according to foreign data, 21-62% of children suffer from AOM in the first year of life, then in Russia - 3%, during the first 5 years of life in the USA and Western Europe, more than 90% of children suffer at least 1 AOM, and we have only 20%. All this indicates a low detection rate of AOM in children, since it is unlikely that there are any objective reasons that explain such huge differences.

Infections of the ENT organs are one of the leading indications for the prescription of antibiotics. In France, more than 3 million are prescribed annually [2], and in the USA there are about 30 million prescriptions for antibiotics for AOM [3].

Pathogens

The main bacterial causative agents of acute infections in otorhinolaryngology are pneumococcus ( Streptococcus pneumoniae

) and Haemophilus influenzae (
Haemophilus influenzae
).
Moraxella ( M. catarrhalis
), (group A b-hemolytic streptococcus (BHSA.
S.pyogenes
) is much less often isolated. The significance of viruses, which in special studies are isolated as the only pathogen in 6% of cases, is unclear. Recently, the first reports of the isolation of
Chlamydia pneumoniae

S.pneumoniae
and
H.influenzae
are of primary importance .

The main viral pathogens are rhinoviruses (25-40% of all viruses), coronaviruses, influenza and parainfluenza viruses. Less common are respiratory syncytial virus, adenoviruses, enteroviruses, reoviruses and picornaviruses. There is no specific therapy against viral infections of the upper respiratory tract. The exception is influenza type A, for which early administration of rimantadine is effective. Several studies have demonstrated the prophylactic effect of interferon (IFN) against rhinovirus infection. Leukocyte g-IFN was used intranasally for 4-5 days [4]. However, for infections caused by other viruses (influenza, parainfluenza, coronaviruses) or Mycoplasma pneumoniae

, the protective effect of IFN was not observed.
When symptoms of rhinovirus infection developed, the use of IFN had no effect on its course. In addition, with long-term use of IFN, irritation of the nasal mucosa (formation of dry crusts, bleeding) was observed. Due to the limited spectrum of activity, the tendency of viral infections to self-heal, and also taking into account the cost of therapy, the use of IFN has not become widespread [5]. The effectiveness of such popular drugs as oxolinic ointment, arbidol, and numerous immunomodulators has not been proven in randomized comparative trials. In general, we can agree with the statement of the prominent American infectious disease specialist J. Barlett, who recently wrote: “There are no antiviral drugs whose effectiveness in treating patients with upper respiratory tract infections has been established” [6]. Thus, the basis for the treatment of viral infections is symptomatic therapy and vis medicamentrics naturae
(healing power of nature - lat.).

We discuss the treatment of so-called acute respiratory infections or acute respiratory viral infections due to the fact that the unjustified prescription of antibiotics, especially for children, for these infections is one of the leading factors in the formation of antibiotic resistance.

Antibacterial therapy in otorhinolaryngology is based on empirical choice. However, it must be remembered that empirical therapy should be based on information obtained in prospective studies.

When planning empirical antibiotic therapy, the physician should ask himself four main questions:

• What is the most likely pathogen that could cause this disease?
• Which antibiotics have been proven effective in randomized clinical trials?
• What is the most likely sensitivity of the suspected pathogen to these antibiotics?
• What local data are available on its sensitivity?

The most difficult question is the last one, since most clinics and hospitals do not have reliable data on the sensitivity of true pathogens (and not contaminating microflora!) to modern antibiotics. Therefore, we will provide general information about the sensitivity of the most likely pathogens of infections of the ENT organs.

Pneumococcus.

Worldwide, the most significant problem in recent years is the rapid increase in resistance to penicillin in combination with resistance to macrolide antibiotics, tetracyclines, co-trimoxazole, oral cephalosporins and sometimes even to third-generation parenteral cephalosporins (cefotaxime, ceftriaxone). There are pneumococci with intermediate sensitivity and resistant. In the treatment of infections caused by strains with intermediate sensitivity, high doses of benzylpenicillin, III (cefotaxime, ceftriaxone) and IV (cefepime, cefpirome) generation cephalosporins, as well as clindamycin, are effective. Of the oral penicillins, the best is amoxicillin, and of the oral cephalosporins, cefuroxime axetil. If pneumococci are resistant to b-lactam antibiotics, vancomycin and rifampicin are used. Promising drugs are third generation quinolones (grepafloxacin, trovafloxacin, etc.), quinupristin/dalfopristin, oxazalidinones (linezolid).

Haemophilus influenzae.

For many otorhinolaryngologists, this pathogen seems to be something exotic, since it is not isolated in most microbiological laboratories. And if this can be done, the results of determining sensitivity very often raise serious doubts. Thus, from domestic laboratories there are reports not just of resistance, but of high resistance to third-generation cephalosporins. This phenomenon has not been described in the world literature. The reason for the errors is the high demands of Haemophilus influenzae on agar and incubation conditions. Therefore, to obtain reliable data and their reproducibility, it is common practice throughout the world to use the recommendations of the US National Committee for Clinical Laboratory Standards (NCCLS). As shown in our laboratory, the domestic AGV medium cannot be used to determine the sensitivity of Haemophilus influenzae.

GABHS, or Streptococcus pyogenes

is the causative agent mainly only for tonsillopharyngitis. As in the case of other pathogens of respiratory infections, the isolation and determination of sensitivity of GABHS in domestic laboratories is carried out very rarely and the results obtained are often questionable. For example, GABHS strains resistant to penicillin or other b-lactam antibiotics have not yet been discovered anywhere in the world, although such results reach the attention of treating physicians and are published in the domestic literature. Using E-tests, we conducted a sensitivity study of GABHS strains isolated in 1994-1996. All GABHS were sensitive to penicillin, amoxicillin, cefaclor and cefuroxime. An alarming 12.6% resistance to erythromycin with cross-resistance to other macrolides (azithromycin, roxithromycin, dirithromycin). Resistance to tetracycline was 60%, which once again confirms the futility of using tetracyclines for tonsillopharyngitis.

Moraxella catarrhalis

(old name -
Branchamella catarrhalis
) is often described in the literature as one of the main causative agents of infections of the ENT organs. However, it seems to us that its importance is somewhat exaggerated. According to our data, even when conducting in-depth bacteriological studies, it is very rare and cannot “compete” with pneumococcus and Haemophilus influenzae. Thus, in the latest series of studies in 80 patients with acute sinusitis, it was isolated in only one case. Moraxella produces b-lactamase in almost 100% of cases and is therefore resistant to penicillin, ampicillin, and amoxicillin. At the same time, she is almost always sensitive to amoxicillin/clavulanate and oral cephalosporins of the third generation. Until recently, it was believed that Moraxella was also always sensitive to macrolides and co-trimoxazole. However, recent data from Spain shows an alarming increase in resistance. Thus, 42%, erythromycin 18%, azithromycin 3% of Moraxella strains isolated from respiratory infections were resistant to co-trimoxazole (E-102, J. Garcia ea A National, Multicenter, and Prospective Survey of Respiratory Bacteria Susceptibility to 12 Commonly Used Antimicrobials in Spain. ICAAC-96). Sensitivity to other macrolides was not determined. In general, the choice of antibiotics in the treatment of this infection does not pose a big problem.

There is no complete unanimity among specialists regarding the prescription of antibiotics for AOM, since in 60 out of 100 cases recovery occurs without the use of antibiotics. Antibiotics are actually needed in only one third of children with AOM, in whom eradication of the pathogen leads to a faster recovery, but identifying these children based on clinical data is difficult, if not impossible.

The tactics for managing children with AOM depends on factors such as the child’s age, the presence of concomitant and background diseases, ENT history, the socio-cultural level of the parents, and the availability of qualified medical care.

• Children under 2 years of age. According to most experts, antibiotics should be prescribed in all cases. If the child’s condition worsens after 24 hours, this may indicate the development of purulent complications that require immediate medical attention.
• In children over 2 years of age, in the absence of severe symptoms of intoxication, pain, or temperature above 38 0C during the day, symptomatic therapy can be limited. However, if symptoms persist or do not improve within 24 hours, antibiotics should be prescribed.

Reassessment of condition

carried out after 48-72 hours. If antibacterial therapy is effective, all the main symptoms of otitis media, except for exudation in the middle ear, should resolve. If this does not happen, then the prescribed treatment is ineffective. In this case, it is necessary to change the antibiotic, for example, instead of amoxicillin, prescribe amoxicillin/clavulanate or ceftriaxone intramuscularly. If indicated, tympanopuncture is performed with mandatory bacteriological examination of the obtained material. If the course of AOM is smooth, the child is examined on the 10-14th day, i.e. after completion of antibacterial therapy. Approximately half of the children still have effusion in the middle ear by this time, but this does not require continued antibiotic therapy.

As already mentioned, AOM is one of the main indications for prescribing antibiotics [7]. However, there is a constant reassessment of the effectiveness of antibiotics for this disease. Currently, three conditions for the effectiveness of antibiotics in AOM are quite clearly formulated: sensitivity of the pathogen to the antibiotic; the concentration of the antibiotic in the middle ear fluid and blood serum is higher than the MIC for this pathogen; maintaining serum concentrations above the MIC for 40-50% of the time between doses of the drug, which ensures 80-85% effectiveness [8]. If a decision is made to prescribe an antibiotic, oral amoxicillin is the drug of choice. Of all the available oral penicillins and cephalosporins, including drugs of the II-III generation, amoxicillin is the most active against penicillin-resistant pneumococci and, for example, is 4 times more effective than ampicillin. As a result, data on resistance to penicillin and ampicillin cannot be extended to amoxicillin. Its additional advantages are 2 times higher blood levels than ampicillin, a significantly lower frequency of unwanted side reactions from the gastrointestinal tract, and ease of administration. Amoxicillin is taken 3 times a day, regardless of the time of food intake, while ampicillin should be taken 4 times a day, 1 hour before or 2 hours after meals, since food reduces the bioavailability of this antibiotic by 2 times.

Exudative (effusion) otitis media

Antibacterial therapy, due to its low effectiveness, is carried out very selectively, especially in cases where hearing loss occurs. The prescription of an antibiotic should be preceded by an observation period of at least 3 months. Most often, amoxicillin is prescribed, the course duration is at least 10 days. If there is no effect, it is possible to conduct a second course of therapy with amoxicillin/clavulanate, the effectiveness of which has recently been proven in controlled clinical trials [9].

For chronic otitis media

Antibacterial therapy plays a secondary role compared to local sanitation and the use of ototopic drugs. It is advisable to use antibiotics if local therapy is ineffective, a clear picture of exacerbation develops and, what is extremely important, under the control of microbiological data, i.e. systemic therapy should be etiotropic [10].

Otitis externa

In localized forms of otitis externa, the main pathogen is Staphylococcus aureus. In some cases, erysipelas may occur involving the auricle and external auditory canal, caused by GABHS. Acute diffuse external otitis (“swimmer’s ear”) and malignant external otitis, which are almost always caused by gram-negative microflora and primarily Pseudomonas aeruginosa, should be distinguished from these forms. In chronic otitis externa, there is usually concomitant chronic otitis media. In such patients, it is necessary to exclude a fungal infection (aspergillus, candida).

Systemic antibacterial therapy must be combined with local treatment (hypertonic solutions, 2% acetic acid solution, 70-96% alcohol, ototopic antibacterial drugs). For staphylococcal otitis, oxacillin, amoxicillin/clavulanate, oral cephalosporins - generations, co-trimoxazole are prescribed; for streptococcal - phenoxymethylpenicillin and macrolides.

For a malignant form, a drug with antipseudomonal activity is prescribed. Considering the need for long courses of therapy (4-6 weeks), the prescription of stepwise therapy with ciprofloxacin is justified (initially intravenous 400 mg 2-3 times a day with a further transition to oral administration 500-750 mg 2 times a day).

Tonsillopharyngitis

When choosing antibiotics, the following must be taken into account: GABHS remains sensitive to penicillin and other b-lactam antibiotics: in some countries there is an increase in resistance to erythromycin and other macrolides; Russian data on the sensitivity of GABHS, obtained by internationally recognized methods, are very limited.

The goals of treatment for pharyngitis caused by GABHS are: reducing the severity and duration of symptoms; prevention of purulent complications, prevention of the spread of GABHS; reducing the risk of developing late complications - rheumatism and glomerulonephritis. Obviously, the last goal is the most important.

The leading drugs for the treatment of tonsillopharyngitis in children and adults are b-lactam antibiotics, and primarily phenoxymethylpenicillin, which is used in the usual daily dose, but not in 4 doses, as with other infections, but in 2-3 doses. Despite the complete sensitivity of pyogenic streptococcus to this antibiotic, the drug cannot be considered ideal for therapy, since phenoxymethylpenicillin must be taken 1 hour before or 2 hours after meals, the course of therapy is 10 days, cases of allergic reactions are not uncommon. In addition, eradication of the pathogen (the most important indicator of microbiological effectiveness) cannot be achieved in 11-16% of patients. One of the factors explaining incomplete eradication is the presence in the deep layers of the tonsils of so-called copathogens - microorganisms that are normal inhabitants of the oropharynx - which produce b-lactamases that destroy penicillin, ampicillin, amoxicillin. In this regard, two additional routes of therapy are possible: firstly, the use of antibiotics of other groups, primarily macrolides (erythromycin, spiramycin, roxithromycin, azithromycin, midecamycin), and in case of allergies to penicillins, macrolides or lincosamides are first-line drugs; secondly, the use of b-lactams that are resistant to the action of b-lactamases. These can be second generation cephalosporins (cefaclor, cefuroxime) or combinations of aminopenicillins with b-lactamase inhibitors sulbactam or clavulanate (ampicillin/sulbactam or amoxicillin/clavulanate). Inhibitor-protected aminopenicillins are more often used as second-line drugs in certain situations. Thus, indications for the use of amoxicillin/clavulanate are relapse of tonsillopharyngitis, the occurrence of tonsillopharyngitis during treatment with penicillin, macrolides.

Epiglottitis

Inflammation of the epiglottis and supraglottic structures is a rare but serious disease that most often occurs in children over 2 years of age. The most common pathogen is Haemophilus influenzae type B, less commonly - GABHS. Given the risk of asphyxia, patients are subject to urgent hospitalization. Parenteral antibiotic therapy should begin immediately after diagnosis. The drugs of choice are ampicillin/sulbactam, third generation cephalosporins (cefotaxime, ceftriaxone).

Acute sinusitis

In this article we will touch only on community-acquired acute sinusitis, in other words, acute sinusitis that developed in outpatients, the treatment of which can be carried out both in outpatient and inpatient settings. The importance of distinguishing this form of sinusitis from chronic sinusitis and nosocomial sinusitis in patients on mechanical ventilation is associated both with the high frequency of infection and with fundamental differences in etiology, pathogenesis and antibacterial therapy.

As the results of computed tomography show, in most cases of acute respiratory viral infection lasting more than 48 hours, an inflammatory reaction of the mucous membrane is noted. This is due to the fact that the paranasal sinuses are lined with mucous membrane, which is a continuation of the mucous membrane of the nasal cavity. Occlusion of the remaining opening due to hyperemia and edema leads to impaired sinus drainage and secondary infection. Thus, in most cases, acute sinusitis develops as a complication of an acute respiratory viral infection, which is observed in 2-5% of patients with ARVI [,]. Other predisposing factors are mechanical obstruction or allergic rhinitis. A common cause of maxillary sinusitis is odontogenic infection.

The most common causative agents of acute sinusitis are S.pneumoniae

and
H.influenzae
,
M.catarrhalis
, staphylococci, and non-spore-forming anaerobes are much less often isolated.
Such results are obtained all over the world with a correctly conducted microbiological study, which involves obtaining material by puncture of the sinuses, inoculating the material on appropriate media (blood, chocolate and anaerobic agars) and incubation at elevated CO2 levels and under anaerobic conditions. Our data obtained from the study of punctate maxillary sinuses in 85 patients show that bacterial pathogens were isolated in 71% of cases. The leading pathogen was S. pneumoniae
, which was isolated from 53% of patients, followed by
H. influenzae
and non-spore-forming anaerobes [13].

The goal of antibacterial therapy for acute sinusitis is to suppress symptoms and shorten the duration of the disease, destroy pathogens, which reduces damage to the mucosa, leading to chronicity of the disease. Adequate antibiotic therapy also prevents the development of intracranial and orbital complications.

Traditional drugs for the treatment of acute sinusitis in adults were oral antibiotics: amoxicillin (in Russia - ampicillin), doxycycline, co-trimoxazole. However, as noted above, such a choice in modern conditions may not always lead to good results. This is due both to the increasing resistance of microflora to these drugs, and in the case of co-trimoxazole with insufficient safety. At the same time, one should remember such an obvious advantage of traditional drugs as their low cost.

The optimal antibiotics for the treatment of sinusitis are penicillins - amoxicillin/clavulanate, cephalosporins - cefuroxime axetil, cefprozil, ceftibuten, macrolides - azithromycin, roxithromycin. Despite the recommendations in the literature for the use of fluoroquinolones (ofloxacin, ciprofloxacin), they should be considered as reserve drugs. This is due not only to their insufficiently high activity against pneumococci, but also mainly due to the fact that these drugs play a very important role in the treatment of inpatients, including those in the intensive care unit. If you suspect the development of intracranial or orbital complications, you should immediately prescribe parenterally, preferably intravenously, third generation cephalosporins (ceftriaxone - 2 g/day once, cefotaxime - 6-8 g/day in 3-4 injections).

Antibacterial therapy should be especially active in the elderly, in patients with impaired immunity, and in the development of orbital or intracranial complications. It is necessary to prescribe one of the antibiotics active against penicillin-resistant pneumococci and b-lactamase-positive strains of Haemophilus influenzae: amoxicillin/clavulanate, ampicillin/sulbactam, cefuroxime, cefotaxime, ceftriaxone. Moreover, with the development of complications from the central nervous system, preference should be given to ceftriaxone (2-4 g/day in 1 injection) or cefotaxime (12 g/day in 4 injections), which are administered intravenously. When pneumococci are isolated, even with intermediate resistance to penicillin, vancomycin is additionally administered (2 g/day in 4 injections).

Chronic sinusitis

In chronic sinusitis, antibiotics play a lesser role than in acute sinusitis, since the main task is to restore normal ventilation of the paranasal sinuses. Antibiotics are used for exacerbation of chronic sinusitis, however, given the frequent release of non-spore-forming anaerobes, the importance of drugs with antianaerobic activity (for example, amoxicillin/clavulanate) increases. In general, it is highly desirable to carry out therapy under the control of bacteriological examination data, especially in patients who have had ineffective antibacterial therapy. When using antibiotics that are not sufficiently active against anaerobes (for example, co-trimoxazole, fluoroquinolones), it is advisable to combine them with metronidazole [14].

Concomitant therapy

Vasoconstrictor drugs, which in foreign literature are called decongestants, play an important role in eliminating swelling of the mucous membrane, thereby improving drainage and restoring the function of the eustachian tube and paranasal sinuses. For decades, topical decongestants have been the most popular in Russia due to the lack of oral medications on the market; in addition, topical remedies were believed to be safer. However, in recent years, views on the use of topical drugs have changed.

When topical decongestants are used for more than 5 days, drug-induced rhinitis develops. In this regard, xylometazoline is the most dangerous. The effectiveness of nasal drops is reduced due to the fact that patients do not know the correct technique for using them, which is that the patient must insert these drops into the nose in the Mecca position and remain in it for 2-3 minutes after instillation of the drops. Obviously, this is very inconvenient for patients, especially for working, elderly, and disabled people [15].

Errors in antibacterial therapy for ENT infections can be divided into three groups.

1.

Neglecting to take antibiotics orally. Antibiotics are important from two points of view. Firstly, they make it possible to alleviate the patient’s condition, speed up recovery and prevent chronic infection. Secondly, their use is necessary to prevent both early and late complications. We too quickly forgot that streptococcal tonsillopharyngitis, with inadequate therapy, leads to the development of rheumatism and glomerulonephritis; acute sinusitis - to meningitis, etc. It is useful to recall a study conducted in 1954 in Sweden by R. Rudberg, which showed a decrease in the incidence of mastoiditis from 17% to almost zero with the use of antibiotics [16].

Attempts to replace oral antibiotics with local antibacterial drugs or drugs with immunostimulating activity declared by the manufacturers currently seem unfounded, since there is no reliable clinical data showing the effectiveness of these drugs. For example, the recommendation for the use of the drug fusafungin - “local treatment of inflammatory infectious diseases of the nasopharynx and respiratory tract: rhinitis, sinusitis, pharyngitis, tonsillitis, laryngitis, tracheitis, bronchitis” - does not indicate that Paul Ehrlich’s dream of a “magic bullet” has finally come true , but that we allow ourselves to be deceived by allowing the publication of such recommendations. In 1997, materials from a symposium devoted to the study of the drug Ribomunil, which was marketed as a specific immunostimulant, were published. The head of the symposium, G. Bellanti (USA), came to the following quite correct conclusions: “further study of this drug, like many other drugs with the potential to stimulate the immune system, is necessary in order to assess their significance” [17].

2.

Wrong choice of drug, doses, routes of administration. Unfortunately, antibiotics are often prescribed without thinking about the most likely pathogen, its sensitivity to antibacterial drugs, and without taking into account the results obtained in controlled clinical studies. Even in outpatient records you can find a prescription like “antibiotic by mouth.” Due to a lack of knowledge, many doctors often equate generics of ciprofloxacin with oral cephalosporins; sulfonamides continue to be the favorite drugs, including “streptocide under the tongue” (!), gentamicin or lincomycin intramuscularly in outpatients.

3.

Insufficient attention to bacteriological research. Despite the fact that the empirical choice of antibiotics forms the basis for their prescription, since, with the exception of streptococcal tonsillopharyngitis, the pathogen cannot be quickly identified, a bacteriological study must be carried out. In addition to the direct benefit for a given patient, for example, if initial therapy is ineffective and the need to change antibiotics, its importance lies in obtaining and accumulating epidemiological data on the structure of pathogens and, most importantly, their sensitivity to antibiotics. Relying on local data on antibiotic resistance makes it possible to make empirical antibiotic therapy as effective as possible and to put it on a scientific basis.

When treating infections of the ENT organs, it is important to overcome nihilism towards the use of antibiotics, which is often found among doctors and is associated with a high rate of spontaneous recovery. Preference should be given to drugs with the highest clinical and bacteriological effectiveness, since infections of the ENT organs affect many millions of patients and small differences in effectiveness in practice result in thousands of cases of ineffective therapy.

How to properly treat a sore throat?

To relieve a sore throat, choose Strepsils® Intensive (honey-lemon lozenges), which contain flurbiprofen, a medicine that has an analgesic effect.

The drug has a local analgesic and anti-inflammatory effect on the mucous membrane of the mouth and throat: it reduces swelling, difficulty swallowing, pain and irritation in the throat4.

The drug does not contain antibiotics and, accordingly, does not increase the risk of developing resistance. The product contains natural honey. Strepsils® Intensive (honey-lemon lozenges) help eliminate sore throat in infectious and inflammatory diseases of the oral cavity and pharynx, regardless of the cause (be it viruses, bacteria or fungi).
