ABSTRACT A quantitative real-time PCR assay was developed for the determination of antiviral drug susceptibility and growth kinetics of human herpesvirus 6. The susceptibility and fitness of a sensitive strain, HST, and its ganciclovir-resistant derivative, GCVR1, were then characterized, leading us to conclude that the mutations of this latter virus did not alter its fitness significantly.

Aim.Evaluation of efficacy, safety, tolerability, and determination of the optimal dose of riamilovir in patients diagnosed with acute respiratory viral infection (ARVI). Materials and methods.The study included 270 patients with uncomplicated ARVI of mild and moderate severity (with a laboratory-confirmed PCR method for the presence of ARVI antigens, absence of influenza virus antigens). Patients were included in the study after signing an informed consent. Patients were randomized into 3 groups in a 1:1:1 ratio of 90 patients in each group. Completed the study in accordance with the Protocol: 267 patients. The study involved patients diagnosed with ARVI. Results.Confirmed the efficacy, safety and tolerability of the drug riamilovir. Adverse drug reactions associated, in the opinion of the doctor, with taking the drug and resulting in discontinuation of the drug, were not noted in this study. Conclusion.As a result of clinical study, the effectiveness of both ARVI treatment regimens with drug riamilovir has been shown. There were no differences in the effectiveness and safety of the proposed treatment regimens. Practical use of both treatment regimens is recommended. However, according to the authors, taking the drug 3 times a day is much more convenient for patients, improves the quality of life and adherence to therapy.

Purpose: to develop an effective and safe method for the etiopathogenetic treatment of influenza patients, aimed at increasing the effectiveness of the existing standard treatment using the antiviral drug oseltamivir.Materials and methods: 150 patients with a verified diagnosis of influenza were taken under observation. All of the participants were divided by randomization into two groups (n1 = 77, n2 = 73) which had the same initial clinical and laboratory characteristics. I group’s patients received standard antiviral therapy using oseltamivir. Patients of the II group at the same time as oseltamivir additionally received an aqueous solution of rehydron for 5 days. All patients underwent determination of the acidity of the mucous membrane of the oropharynx immediately before the start of antiviral therapy and immediately after its completion.Results: patients additionally receiving rehydron had a more rapid leveling of the main symptoms of influenza and a decrease in the frequency of its complications compared with people who received only standard treatment.Conclusions: the developed method of etiopathogenetic treatment of patients with influenza is characterized by a proven level of effectiveness, which is associated with the corrective effect of rehydron on the acid-base balance of the mucous membranes of the respiratory tract. The data obtained in the course of the study indicate not only the absolute scientific novelty of the developed method, but also its applied significance for practical public health.
