Introduction. Epstein-Barr virus causes recurrent infectious mononucleosis-like symptoms. Today it is shown that the poisons of insects and animals are rich sources of antimicrobial substances (peptides) and contain a wide range of active biological compounds. Antimicrobial peptides play an important role in the immune response of the innate immunity of the host in the presence of pathogenic microorganisms. Russia has developed an antiviral drug Allokin-alpha on the basis of antimicrobial peptides. The active ingredient of this drug is cytokin-like peptide alloferon. The aim of the study is to evaluate the effect of allokin-alpha therapy on the amount of EBV DNA in saliva samples and clinical complaints in patients with chronic Epstein-Barr infection (ChEBVI). Material and methods. 59 patients with ChEBVI were examined (45 women and 14 men; mean age 32.52 ± 1.75 years). Patients were examined quantification of DNA Epstein-Barr virus in saliva samples by the method of polymerase chain reaction (PCR) with hybridization-fluorescence detection in “real time” mode. The analytical sensitivity of the test system is 400 copies / ml. Patients were randomized into two groups: group 1 (25 patients) received Allokin-alpha therapy (9 injections of s / c, 1.0 mg every other day); group 2 (33 patients) received Valtrex (500 mg x 2 times / day, by mouth) for two months. Results. 59.67% of patients had negative PCR results after treatment with Allocin-alpha. Only 27.27% of patients had negative PCR results after two months of treatment with Valtrex. In a correlation analysis, a significant effect of the initial number of copies of DNA EBV on the severity of clinical complaints in patients was revealed in the general group ChEBVI. Discussion. Allokin-alpha improves the recognition of virus-infected cells and helps suppress viral replication. Conclusions. Allocin-alpha therapy can be recommended for the treatment of chronic EBVI at a dose of 1 mg subcutaneously every other day with a course dose of at least 9 injections.

Introduction. Epstein-Barr virus (EBV) causes recurrent infectious mononucleosis-like symptoms. Today poisons of insects and animals were shown to be rich sources of antimicrobial substances (peptides) and contain a wide range of active biological compounds. Antimicrobial peptides play an important role in the immune response of the host’s innate immunity to pathogenic microorganisms. Based on antimicrobial peptides in Russia, an antiviral drug allokin-alpha has been developed. The active ingredient of the drug is cytokine-like peptide alloferon. The purpose of the study is to evaluate the effect of allokin-alpha therapy on the amount of EBV DNA in saliva samples and clinical complaints in patients with chronic Epstein-Barr viral infection (EBI). Material and methods. 59 chronic EBI patients (45 women and 14 men; mean age 32.52 ± 1.75 years) were examined. Patients were subjected to quantitative determination of Epstein-Barr virus DNA in saliva samples by the method of polymerase chain reaction (PCR) with real-time hybridization-fluorescence detection. The analytical sensitivity of the test system is 400 copies/ml. The patients were divided into two groups: 26 patients who received allokin-alpha therapy (9 injections subcutaneously with 1.0 mg every other day) were included in the 1st group; the 2nd group included 33 patients who received Valtrex (500 mg 2 times/day, orally) for 2 months. Results. After treatment with allocin-alpha, negative results of PCR were obtained in 59.67% of patients. After two months of Valtrex therapy, negative PCR results were obtained in only 27.27% of patients. The correlation analysis revealed a significant effect of the initial number of copies of EBV DNA on the severity of clinical complaints in the general group of EBV patients. Discussion. Allokin-alpha improves the recognition of virus-infected cells and helps to suppress viral replication. Conclusion. Allokin-alpha therapy can be recommended for the treatment of chronic EBV infection in a dose of 1 mg subcutaneously every other day with a course dose of at least 9 injections.

A total of 60 patients (38 women and 22 men, 36,54±2,14 years old) with a Epstein - Barr infection were examined. The patients were divided into two groups depending on the treatment regimen: 1 group - 34 patients received ingaron therapy (10 intramuscular injections of 500000 units every other day); group 2-26 patients received valcyte (450 mg 2 times a day, by mouth, 2 months) + ingaron at the same dosage. One month after the end of antiviral therapy in the1st group, negative results of half-chain reaction were obtained only in 29,41% of patients. The combination of valcyte and ingaron in patients of the 2nd group was different and differed in the duration of the injection of ingarone: 2a group: ingaron10 injections of 500000 IU intramuscularly every other day; 2b group: ingaron 20 injections of 500000 IU intramuscularly every other day; 2c group: ingaron 10 injections of 500000 IU and 15 injections of 100000 IU intramuscularly every other day. The best result after the introduction of ingaron was obtained in 90% of patients who received the longest course of ingaron in the form of 20 injections of 500000 IU every other day in combination with valcyte. In the other groups, where the total dose of ingaron was lower, positive results were found in 60 and 66,7% of patients. A significant positive change in the number of copies of deoxyribonucleic acid Epstein - Barr virus was found in samples of saliva and the severity of clinical complaints in patients one month after the ingaron monotherapy or combination therapy (valcyte and ingaron) was completed. The best effect of treatment with ingaron is achieved in patients with chronic Epstein - Barr infection with the prolonged introduction of ingaron (at least 20 injections).
