Comparative clinical efficacy of medicine in non-specific prevention of influenza and acute respiratory viral infections in children during the period of seasonal increase incidence
Abstract
Objective: comparative open-label randomized study of the safety and efficacy of the drugs Alpha-glutamyl-tryptophan + Ascorbic acid + Bendazole («Cytovir-3«) and Umifenovir for prophylactic influenza and acute respiratory viral infectionsin children aged over 6 in organized groups.Materials and methods. 207 healthy children ≥6 years old of organized educational groups. According to study protocol they were divided into 2 groups: 102 children were randomizes to receive Alpha-glutamyl-tryptophan + Ascorbic acid + Bendazole (Сytovir-3, Group 1), capsules (JSC MBSPC «Cytomed«, Russia) while 105 children were randomizes to receive Umifenovir 100 mg (Group 2) capsules (Pharmstandart Leksredstva, Russia). The frequency of adverse reactions on drugs and adverse events was assessed while taking drugs and within 3 weeks after. Efficiency was assessed by calculate value of prophylactic efficiency index in comparison groups. Efficacy was analyzed on the basis of the comparative incidence of children included in the study with a total incidence in Saint-Petersburg.Results: the studied drugs showed a high safety profile and match preventive clinical efficacy against influenza and acute respiratory viral infections. Both drugs during prophylactic administration stimulated the production of secretory IgA. A tendency to a decrease in the incidence of acute respiratory viral infections in groups of children taking the studied drugs was revealed and compared with general indicators reflecting the integrated epidemic situation of influenza and other acute respiratory viral infections in Saint-Petersburg during the study. The data obtained allow us to recommend the use of the drug Alpha-glutamyl-tryptophan + Ascorbic acid + Bendazole («Сytovir-3«) (dosage form – capsules) for the prevention of respiratory diseases in organized children’sgroups during the period of seasonal increase in the incidence of influenza and acute respiratory viral infectionsin.
