Sensitivity of various influenza virus strains to arbidol. Influence of arbidol combination with different antiviral drugs on reproduction of influenza virus A

Leneva IA, Fediakina IT, Gus'kova TA, Glushkov RG.

AIM: To study antiviral activity of arbidol in relation to various antigenic subtypes of influenza virus isolated from humans; efficacy of arbidol action in combination with adamantanic antiviral drugs, ribavirin and ribamidil on reproduction of influenza virus A (IVA) in cell culture. MATERIAL AND METHODS: The activity of the drugs against viral reproduction was assessed by inhibition of viral antigens expression detected in virus-infected cells using enzyme immunoassay (EIA). RESULTS: Arbidol is just as good as adamantanic drugs, neuraminidase inhibitors, ribavirin and ribamidil by its inhibiting activity in relation to influenza viruses A and B. Arbidol inhibits reproduction of human IVA antigenic strains H1N1, H2N2, H3N2 and remantadin-sensitive and remantadin-resistant strains of influenza virus. Arbidol inhibits reproduction of pathogenic for humans strains of avian influenza virus H5N1 and H9N2, strains H6N1 and H9N2 having internal genes common with H5N1 and H9N2. The inhibiting activity of arbidolin on cell culture viral reproduction enhanced if arbidol was used in combination with amantadine, remantadin, ribavirin and ribamidil. CONCLUSION: Arbidol has a wide spectrum antiviral activity and inhibits reproduction of various antigenic subtypes and remantadin-resistent human IVA, avian viruses H5N1 and H9N2, influenza viruses B and C.

T. A. Semenenko, E. P. Seikova, T. P. Gotvyanskaya, A. D. Gaidarenko, N. A. Polezhaeva, L. F. Evseeva, O. G. Nikolaeva

The results of the comparative analysis of the immunological effectiveness of the anti-influenza vaccine Vaxigrip, the interferon inductor arbidol and their combination in 125 elderly persons are presented. In the process of investigation, the immunomodulating activity of the preparations under study was noted. This activity was manifested by the increase of the absolute and relative number of cells carrying CD3+, CD4+ and CD16+ markers, but not CD8+, CD19+ or CD25+; normalization of the immunoregulatory index and stimulation of phagocytic function without significant influence on the level of HLA-DR+ expression or on the concentration of the main classes of immunoglobulins. An increase in the frequency of seroconversions and the multiplicity of growth in the titers of specific antibodies to influenza viruses A (H1N1 and H3N2) and B, most pronounced in persons given arbidol along with an anti-influenza vaccine, was established.

An antiviral drug arbidol (1-metyl- 2-pheny l-thiomethy l -3-carbotoxy- 4-dimetylaminomethyl- 5-hydroxy- 6-bromoindolehydrochloride monohydrate) is widely used for prophylaxis and therapy of influenza A and B in Russia. The study of effect of arbidol on viral replication showed that arbidol inhibited viral reproduction of all antigen subtype of human influenza A and B viruses, avian influenza viruses, possessing H5 and H9, and rimantadine-resistant strains of influenza A viruses. Arbidol demonstrated broad-spectrum antiviral activity against respiratory viruses inhibiting RSV and adenovirus type 3 viral replication in cell culture.

Arbidol was previously shown to inhibit early stage of influenza A virus replication. The studies of the arbidol effect upon replication of panel of reassortants between A/Singapore/1/57(H2N2) and A/Chiken/Germany/27 (Weybridge strain, H7N7) showed that the greater sensitivity of the Weybridge virus to arbidol was determined by the HA gene; there was no correlation between sensitivity to arbidol and any other gene Arbidol-resistant mutants were obtained by passing viruses in MDCK cells in the presence of increasing drug concentrations. Mutants selected for resistance to arbidol promoted membrane fusion at higher pH (0.2–0.4) than wild-type virus. Arbidol inhibited haemolysis induced by the wild-type virus, but did not inhibit the haemolysis induced by arbidol-resistant mutants. To determine the molecular basic of the arbidol-resistance the HA genes of the wild-type and arbidol-resistant mutants were sequenced.

All mutants had amino acid substitutions only in HA2 subunit, but at different positions. The study of the effect of arbidol on conformation of the HA using conformational antibodies showed that arbidol caused conformational change in the structure of HA of wild-type virus, but not in arbidol-resistant mutants. The data indicate that the target of arbidol is the HA and that arbidol increases its stability to low pH-induced changes and as a consequence inhibits membrane fusion during virus infection.

Arbidol used in the prophylaxis of acute respiratory viral infections and their complications in servicemen

Shuster AM, Shumilov VI, Shevtsov VA, Mar'in GG, Kozlov VN.

The prophylactic action of arbidol to prevent the acute respiratory viral infections and their complications (extra-hospital pneumonia) was studied under conditions of two military collectives during winter and summer time. The data obtained confirm the prophylactic activity of the drug in respect of acute respiratory viral infections. Regardless of the degree of disease epidemic rise among the servicemen who didn't take arbidol the minimal threshold of influenza and other acute respiratory viral infections incidence (10-15%) remained in the experimental group. The incidence of pneumonia decreased. It was connected with decrease in viral-and-bacterial pneumonia. The number of patients with bacterial (generally pneumococcal) pneumonia didn't change.

Department of Respiratory Disease, PUMC Hospital, CAMS and PUMC, Beijing 100730, China.

OBJECTIVE: To evaluate the efficacy and safety of Arbidol in the treatment of naturally acquired influenza. METHODS: A randomized, double-blinded, placebo controlled trial was conducted. Subjects were enrolled. The inclusion criteria included: aged 18 to 65 years, presented within 36 hours of onset of influenza symptoms; and had documented temperature of 37.8 degrees C or higher during an influenza outbreak in the community. Individuals were randomly divided Arbidol group (200 mg three times daily for 5 days) or placebo group.

RESULTS: Totally 232 individuals were recruited and received medication and follow-up. All of them were qualified to be analyzed for safety as intent-to-treat population (ITT) (113 Arbidol, 109 placebo). Twenty-two (9.48%) were during follow-up or refused to continue the trial, and 210 completed as scheduled and identified as PP population (102 Arbidol, 108 placebo). Totally 125 individuals were identified as influenza-infected through laboratory test, which was defined as PPi population (59 Arbidol, 66 placebo). In PPi population, the cumulative alleviation proportion of Arbidol group was significantly higher than that of placebo group. The median duration of illness was 72.0 hours (95% confident interval (CI) 66.00-78.00 hours) in Arbidol group and 96.0 hours (95% CI 87.46-104.54 hours) in placebo group. The median area under the curve (AUC) of decreased total score were significantly higher in Arbidol group than in placebo group, which were 780.00 and 684.00 score-hours respectively. For PP population, similar results were seen. Adverse events reported were similar in Arbidol group and in placebo group. The main adverse events were gastrointestinal symptoms and increased transaminase.

CONCLUSION: Arbidol was effective and well tolerated in the treatment of early naturally acquired influenza.

Experience of the application of Arbidol with treatment and preventive maintenance of influenza and ORVI in children in the Ukraine

S.A. Kramarev, L.A. Is chamber National medical university, Kiev, the Ukraine

Influenza and sharp respiratory virus infections (ORVI) are the diseases most common in the Ukraine. Yearly in the country are recorded tens of millions of cases ORVI, millions of days of disablement, passages of school, connected with them. Economic damage from the influenza only composes about 400 million 10 kopecks per year [ 6 ]. During only one first calendar quarter after the medical aid apropos of influenza and ORVI in the Ukraine they are turned to 10 million people, among whom 52% comprise the children. The level of morbidity ORVI exceeds the same of all remaining infections among the children 7-7.5 times. A quantity of sick ORVI of children is 1.5-3.0 times more than adult [2]. For the children the influenza and ORVI are most dangerous. At this age most frequently are encountered the defeats of central nervous system, from the light neurologic disorders to the heavy defeats of brain, such complications as bronchitis, pneumonia, acute average otitis are recorded in each third child, sick with influenza and ORVI. The younger the child, the greater he has the probability of the development of complications. This probability decreases by 20% each of the subsequent 6 years of the life of child [ 11 ]

REPORT on the program of the estimation of the effectiveness of the medicine of "Arbidol" in the preventive maintenance and the treatment of influenza and sharp respiratory virus infections in soldiers.

Moscow 2002

The problem of acute respiratory diseases for the military associations with the high risk of the development of the infections of the respiratory tract is especially urgent. In particular, in the newly formed parts, training centers, parts from the composition of united groupings of troops in the local military conflicts and the peacemaking forces. Under the contemporary conditions respiratory diseases are predominantly the infections of those organized associations, where the conditions determine the activity of the mechanism of the transfer of agents and the heterogeneity of the composition of people. As the starting gear of the making more active of epidemic process with ORZ in the military associations serves their renovation. As proof serve lifts in the annual dynamics of morbidity connected with the calls in VS RF.

Use in the real practice of the developed positions on an improvement in the quality of preventive maintenance and treatment of sharp respiratory infections with the use of arbidol makes it possible to decrease morbidity, to increase the effectiveness of therapeutic measures and to optimize the expenditures, connected with the acute respiratory diseases in soldiers.

Study of the effect of antiviral drugs on the reproduction of the respiratory syncytial virus by enzyme immunoassay

Leneva IA, Sokolova MV, Fediakina IT, Khristova ML, Fadeeva NI, Gus'kova TA.

A test system based on EIA was developed for evaluating the efficiency of drugs active towards the respiratory syncytial virus (RSV) in cell culture. Virasole and its structural analog ribamedii active towards RSV infection and arbidol whose activity in RSV infection is unknown were tested. Like virasole and ribamedil, arbidol inhibited the expression of RSV antigens, the inhibitory effect increasing with the drug concentration and decreased with increase of the multiplicity of virus infection. MIC50 for arbidol, virasole, and ribamedil were 10, 5, and 6 micrograms/ml, respectively. These data prompt clinical trials of arbidol in RSV infection.

Approaches and strategies for the treatment of influenza virus infections

Joseph M Colacino, Kirk A Staschke, and W Graeme Laver

Influenza A and B viruses belong to the Orthomyxoviridae family of viruses. These viruses are responsible for severe morbidity and significant excess mortality each year. Infection with influenza viruses usually leads to respiratory involvement and can result in pneumonia and secondary bacterial infections. Vaccine approaches to the prophy-laxis of influenza virus infections have been problematic owing to the ability of these viruses to undergo antigenic shift by exchanging genomic segments or by undergoing antigenic drift, consisting of point mutations in the haemagglutinin (HA) and neuraminidase (NA) genes as a result of an error-prone viral polymerase. Historically, antiviral approaches for the therapy of both influenza A and B viruses have been largely unsuccessful until the elucidation of the X-ray crystallographic structure of the viral NA, which has permitted structure-based drug design of inhibitors of this enzyme. In addition, recent advances in the elucidation of the structure and complex function of influenza HA have resulted in the discovery of a number of diverse compounds that target this viral protein. This review article will focus largely on newer antiviral agents including those that inhibit the influenza virus NA and HA. Other novel approaches that have entered clinical trials or been considered for their clinical utility will be mentioned.

Arbidol Childrens Study English (babblefish .html) (or .pdf)

REPORT "Arbidol in the preventive maintenance of the influenza and other sharp respiratory virus infections in children at the age is older than 6 years".

Sharp respiratory infections relate to the number of most extended diseases of man and compose half or more from the total number of acute diseases (Pilar Orine F.J. and co-auth., 1998). As early as 1979 by the World Health Organization (WHO - WORLD HEALTH ORGANIZATION) it was recomended to the scientific research associations focus first priority attention on the development of the effective methods of preventive maintenance and timely diagnostics of respiratory pathology in children. After practically quarter of century the problem of respiratory infections in children became even more urgent. The diseases of the organs of respiration - most frequent pathology in children (Kagans S.YU. and co-auth., 1998), which specifies the expediency to isolate sharp respiratory infections into the separate group of the diseases of respiratory system. The results of epidemiological studies attest to the fact that on the average each child transfers from 3 to 5 episodes ORZ per year (Korovin N.A. and co-auth., 1998).

Obtained data clinically base the expediency of using Arbidol with the therapeutic and prophylactic purpose in the categories of children being investigated and are the basis of the guarantee of a data base for further estimated studies in the real practice.

Research Institute of Grippe, Russian Academy of Medical Sciences, St. Petersburg.

Therapeutic efficacy of remantadine and arbidole was studied in the clinical and laboratory observation of pediatric in- and outpatients with grippe and mixed viral infections in various seasonal epidemic. In the trial of remantadine 742 school children and 60 children at the age of 3 to 6 years with type A, B or A + B influenza, influenza in association with other acute viral respiratory tract infections or acute viral respiratory tract infections of nongrippe etiology were observed. 402 and 400 of them were given remantadine and placebo respectively. The drug was used in a single dose of 1.5 mg/kg body weight 3 times a day for 3 days. In the trial of arbidole 158 children at the age of 1 to 14 years with type A influenza, influenza + acute viral respiratory tract infection and acute viral respiratory tract infection of nongrippe etiology were observed. The arbidole daily dose of 10 mg/kg body weight was given in 4 portions for 5 days. Both the drugs were shown to be therapeutically efficient in all the grippe types and acute viral respiratory tract infections. The highest efficacy was observed when the use of the drugs was started at the early stages. With the use of the drugs the periods of fever, other intoxication signs and virus isolation decreased. No adverse reactions were recorded. The drugs had no inhibitory effect on the cellular and humoral immunity and on production of antiviral antibodies. The dynamics of the indices of the cellular immunity and macrophages confirmed the arbidole immunostimulating action.

The protective action of arbidol during a rise in respiratory diseases in 1990

Obrosova-Serova NP, Burtseva EI, Nevskii IM, Karmanova RI, Nazarov VI, Pitkenen AA, Slepushkin AN.

Prophylactic properties of a new chemical drug, arbidol, against acute respiratory diseases (ARD) were studied. Arbidol given daily in a dose of 0.2 g for 19 days reduced the morbidity rate 2.3-fold in adults during an outbreak of ARD. Geometric mean titres of antibodies to respiratory viruses among healthy persons did not change after treatment with arbidol indicating the lack of immunosuppressive properties in the drug. The prophylactic effect of arbidol may be due to both specific effect of the drug on influenza and parainfluenza viruses, and its interferon-inducing and immunity-stimulating properties.
