At present time, a number of questions regarding the pathophysiological characteristics and therapeutic approaches to the treatment of the new coronavirus infection COVID-19 remain unresolved. In some cases, patients with COVID-19 may experience symptoms of gastrointestinal tract disorder. According to the literature, the new SARS-CoV-2 coronavirus can replicate in the gastrointestinal tract and may affect the gut microbiota. The article aims to review studies about the possible relationship between the gut microbiota condition and the course of COVID-19 infection, as well as to consider the gut microbiota as a potential therapeutic target and probiotic drugs as possible therapeutic agents in the treatment of viral infections, including COVID-19 infection. It is known that gut microbiota condition is one of the factors determining the susceptibility and features of the bodys response to various infectious agents, possibly including the COVID-19 infection. Currently published studies demonstrate a possible relationship between the gut microbiota condition and the course of COVID-19 infection, however, to confirm this hypothesis, additional studies are required, which will allow to make more unambiguous conclusions with subsequent development of new approaches to the prevention and treatment of infection. Potentially a lot of hope in this direction is inspired by the results of probiotics studies, which showed that their use may reduce the frequency and severity of viral infections of the upper respiratory tract. However, currently, there is insufficient data to extrapolate the results of these studies to COVID-19 patients.

Abstract The gastrointestinal tract of mammals is home to a dense population of microbes which influence host physiology and health. One of the most concrete ways that the gut microbiota impacts host biology is through the production of hundreds of chemically diverse small molecules. These molecules are absorbed into the bloodstream, where they reach concentrations similar to those achieved by pharmaceuticals and bind host receptors leading to changes in cellular and organ physiology. Here I will summarize recent work from our group and others that show how microbially sourced metabolites alter health and physiology of the host. I will also discuss how mechanistic studies of small molecules from the microbiota are enabling new therapeutic approaches to harness the metabolic potential of the gut microbiota.

Inflammatory Effect

Various methods and variants of nasal cavity irrigation are one of the most ancient in the treatment and prevention of diseases of the upper respiratory tract. When choosing a remedy for elimination and irrigation therapy, preference is given to preparations based on sea water, containing in its composition minerals and trace elements that cause additional therapeutic effect. A new direction in this type of therapy is the use of drugs containing fucoidans (obtained from brown algae extract). Their immunostimulatory and anti-inflammatory effect can improve the effectiveness of elimination and irrigation therapy in symptomatic treatment of ARVI / influenza and their complications (sinusitis, adenoiditis).

Respiratory Viral Infections

According to WHO, the respiratory system diseases are currently inside the ten most common pathologies. The modern strategy for treating influenza and ARVI gives priority to the antiviral and immunostimulating agents, but the symptomatic drugs, which include preparations based on silver and its compounds, also play an important role. The large positive experience in using silver preparations supported by numerous clinical studies shows their high efficacy and satisfactory safety profile in the treatment of infectious and inflammatory diseases of the nose and upper respiratory tract in children and adults.

Coronavirus Infection

The new coronavirus infection COVID-19 that appeared at the end of 2019 is signifi cantly different from the viral infections that existed previously. The new SARS-CoV-2 coronavirus combines two transmission routes—aerosol and oral-intestinal. The targets for this virus are both cells of the respiratory system and the human gastrointestinal tract. Along with the classical form of this disease, the so-called “gastrointestinal” form is described, in which the clinical picture is dominated by signs of damage to the gastrointestinal tract (diarrhea, vomiting, anorexia). These symptoms are detected, in general, in 20% of patients with COVID-19. More than 80% of patients have mild forms, a third of these individuals had diarrhea. Although SARSCoV-2 viral RNA is detected in faeces samples of patients with COVID-19, it does not carry an infectious onset, and not a single case of fecal-oral transmission has been confi rmed. Since the intestines are the most powerful organ of our immune system, we can introduce SARS-CoV-2 viral RNA into the gastrointestinal tract to ensure the formation of immunity to this infection.

Abstract Background Respiratory viral infections in HCT recipients are associated with high morbidity and mortality, especially after progression from upper respiratory tract infection (URI) to lower respiratory tract infections (LRI). Data on risk factors (RF) for LRI and mortality is lacking for HCoV infections after HCT. We aimed to validate our ISI in HCoV infections. Methods All adult HCT recipients with HCoV infection from 2015 to 2017 were evaluated. An ISI based on RF was used to classify patients as low (0–2), moderate (3–6), or high (7 or higher) risk for progression to LRI or death. We defined LRI as HCoV detected in nasal wash and/or bronchoalveolar lavage and new lung infiltrates on diagnostic imaging. Clinical parameters were collected and ISI were calculated for comparison. Results A total of 144 adult HCT recipients with 166 episodes of HCoV infections were analyzed. The most common HCoV serotype for LRI and URI was 229E (42.4%) and OC43 (37.6%), respectively, and most patients were infected between November and March each year (Figures 1 and 2). When compared with URI, patients with LRI were more likely in the pre-engraftment period, had multiple respiratory viruses infections, had nosocomially acquired HCoV, required hospitalization, ICU transfer, and mechanical ventilation (all, P < 0.05). Overall mortality rate was 4% at Day 30 from diagnosis and all patients who died had LRI with an 18% mortality. Among those who died, 33% had nosocomial infection, 67% were co-infected with another respiratory virus and 67% required mechanical ventilation. Using an ISI cut off of <4, the negative predictive value (NPV) for progression to LRI was 86% with a specificity of 76%. Conclusion HCT recipients with HCoV LRI were more likely to have a fatal outcome. The NPV of the ISI for progression to LRI was high and could be used as a prognostic tool for future studies and for therapeutic clinical trials. Disclosures All authors: No reported disclosures.

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder that causes isolated thrombocytopenia. Many viruses have been identified as triggering the autoimmune process, including HIV, MCV, EBV, parvovirus, rubella and measles. However, ITP in association with coronavirus infection has not previously been reported. We describe the case of a healthy man who presented with severe ITP complicated by intracranial haemorrhage following upper respiratory tract infection. An infection screen revealed coronavirus infection.

An estimated 50% of antibiotic prescriptions may be unjustified in the outpatient setting. Viruses are responsible for most acute respiratory tract infections. The viral infections are often self-limiting and only symptomatic treatment remains effective. Bacteria are involved in a small percentage of infections etiology in this area. In the case of a justified or documented suspicion of a bacterial infection, antibiotic therapy may be indicated. Based on the Polish „Recommendations for the management of non-hospital respiratory infections 2016”, the indications, the rules of choice, the appropriate dosing schedules and the therapy duration, in the most frequent upper respiratory tract infections in adults, have been presented. Implementation of the presented recommendations regarding our Polish epidemiological situation, will significantly reduce the tendency to abuse antibiotics, and thus will limit the spread of drug-resistant microorganisms.

Acute infections of the upper respiratory tract and upper gastrointestinal tract (mouth and throat) are still the most common reason for reporting to the general practitioner or ENT specialist. Despite the fact that the most common causative agent of these diseases are virurs, antibiotics are still flavored in about 60-80% of patients who report to the doctor. In consensus such as EPOS, WHO reports and other local / national reports, there is a need to limit antibacterial treatment for symptomatic and anti-inflammatory drugs. In addition to intranasal steroids and mucocutaneous decongestants, supplementary treatment should be considered which resolves persistent symptoms. Plant preparations are used here. The growing role of rational phytotherapy is emphasized, especially due to the most frequent etiological factor of these infections, i.e. viruses. Modern phytotherapy is part of pharmacology, and all preparations based on plants meet the standards for medicines and are subject to standard registration procedures. The article discusses the use and mechanism of action of selected herbs, among others: sorrel, elderberry, yarrow and horsetail in the treatment of upper respiratory tract infections and upper gastrointestinal tract. The phytotherapy show good efficacy and tolerance, and can be used both in children and adults in recurrent infections of the upper respiratory tract. It is worth paying attention to the combined preparations, the components of which have the effect confirmed by randomized trials and long-term registration for use in treatment, both during the first signs of cold and its further duration, and supportive in chronic inflammation especially of the paranasal sinuses.
