Rational treatment of acute rhinosinusitis in the context of increasing antibiotic resistance.

Acute rhinosinusitis is one of the most common diseases in the population, both in primary and specialist otolaryngological care. It is also responsible for a disturbingly high percentage of prescribed antibiotic therapy, regardless of the etiology of the disease. Despite the fact that acute viral and acute postviral rhinosinusitis dominate among the phenotypes of acute rhinosinusitis, and the development of acute bacterial rhinosinusitis occurs in only 0.5-2% of all cases in adults and 5-10% in children, antibiotics still remain an important element of treatment, despite alarming data on the growing antibiotic resistance and the adverse effect of antibiotics on the human microbiome, leading to dysbiosis. The discovery of antibiotics was one of the greatest achievements of modern medicine, but their inappropriate use leads to the gradual increase in the phenomenon of antibiotic resistance, considered one of the most serious public health problems, recognized by the WHO as one of the 10 greatest threats to human health in the 21^st century. The unjustified use of antibiotics in outpatient care is the key to the growth of this problem, in parallel with the lack of patient compliance. The COVID pandemic has intensified this unfavourable trend. That is why the knowledge of antibiotic stewardship is so important. According to the guidelines, in the therapy of acute rhinosinusitis, symptomatic and anti-inflammatory treatment dominates, and antibiotic therapy has very strictly defined and limited indications. The latest guidelines also recommend herbal medicines, including BNO 1016, in the treatment of acute viral and postviral rhinosinusitis. Available studies indicate that it has a beneficial effect not only on shortening the duration of the disease and reducing symptoms, but also reduces the need for antibiotic treatment in acute rhinosinusitis. Complications of acute rhinosinusitis are relatively rare and are not related to taking antibiotics.
