Proteflazid® effectiveness for prevention and treatment of acute viral respiratory infections in the conditions of COVID-19

The original antiviral drug Proteflazid® has been used in clinical practice since the early 2000s for the etiotropic treatment of acute respiratory viral diseases, due to its property of blocking viral RNA and DNA polymerases. Considering that at the beginning of the global COVID- 19 pandemic, caused by RNA-containing virus of SARS-CoV-2 species in 2020, the ability of the drug active substance to inhibit the activity of 3CL- protease of the SARS-CoV-2 coronavirus was shown by molecular docking and, subsequently, to confirm the property of the active substance to block the reproduction of the SARS-CoV-2 virus in cell cultures in vitro. It was extremely important to test the effectiveness of the drug Proteflazid, drops for the prevention and treatment of COVID-19 disease at "off labell use".

AIM

The aim of the study was to provide a statistical assessment of the effectiveness of the drug Proteflazid®, drops in terms of COVID-19 pandemic.

MATERIALS AND METHODS

The analysis has been performed including the letters-references from medical institutions from different regions of Ukraine about the effectiveness of the drug Proteflazid®, drops. Methods of statistical analysis have been focused on dynamics and structure analysis, meta-analysis, generalization, etc.

RESULTS

90 letters-references about the effectiveness of the drug Proteflazid®, drops, during the prevention and treatment of acute respiratory viral infections, including COVID-19 diseases were analyzed. The study used references that contained the most complete information. The number of deleted letters-references is 11. Lettersreferences from 79 medical institutions from different cities and regions of Ukraine were analyzed. The period of starting taking the drug by employees and patients of medical institutions began on February 27, 2020. Final information - October 01, 2020. The vast majority of letters from medical institutions indicated that medical staff were in contact with patients potentially suffering from COVID-19. This means a high risk of being infected with Coronavirus infection. Total number of patients who took Proteflazid® for preventive purpose was 8,572, including 7,444 medical workers and 1,128 ordinary patients. Indicator "Number of fatalities" for the medical institutions providing such information was "0". Total number of patients who took Proteflazid® for therapeutic purposes was 433, including 23 medical workers and 410 ordinary patients. Indicator "Number of fatalities" for the medical institutions providing such information was "0". The total number of medical personnel and patients who used Proteflazid drops for preventive and therapeutic purposes was 9005 people.

CONCLUSIONS

The statistical analysis confirmed the effectiveness of the drug Proteflazid® for the prevention and treatment of COVID-19, as, when compared with official actual data, regarding the main indicators of the incidence of COVID-19: there were no fatalities; the average treatment period decreased (1.8 times); the proportion of recovered increased (at least 1.5 times); the proportion of sick medical workers in the total population of sick medical workers decreased (2.2 times); the proportion of patients with a severe course decreased (3.3 times). It can be argued that the drug Proteflazid®, drops has shown high effectiveness in the prevention and treatment of acute respiratory viral infections, including COVID-19, among medical personnel and patients.

Analysis of the clinical trial results of the flavonoid effects on some cellular immunity indicators in children and adults

In the scope of this paper, an analysis of the clinical trial results assessing the clinical and immunological efficacy of the effects of flavonoids on some indicators of immunity in children and adults is given.

AIM

The aim of the study was to evaluate the effects of flavonoids on the cellular component of the immune system in children and adults with viral and viral-bacterial diseases by using meta-analysis and statistical analysis of the clinical findings.

MATERIALS AND METHODS

The analysis comprises 5 scientific sources with the results of controlled clinical trials involving 412 children and 15 sources involving 1493 adult patients during the period from 2003 to 2017. In analysis Student's t-test was applied.

RESULTS

The data obtained indicate the efficacy of flavonoids in the treatment of viral and viral-bacterial diseases in children and adults. The administration of flavonoids (Proteflazid®, Immunoflazid®, Flavozid®) in the treatment of children with acute respiratory diseases and adults with HHV infection contributes to the normalization of cellular immunity indicators, the HHV infections symptom resolution, and the relapse rate reduction of genital herpes caused by HHV infection.

CONCLUSIONS

Therapy with such medical products as Proteflazid®, Immunoflazid®, Flavozid® helps to improve the clinical status and normalize the cellular immunity indicators in patients who were administered a treatment course.

Proteflazid®: outcome analysis of clinical trials studying the impact of human herpesvirus infection on some cellular immunity indicators and gestation course in women

An outcome analysis of the clinical trials evaluating the clinical and immunological efficacy of the drug Proteflazid® in the treatment of diseases associated with herpesvirus infection in pregnant women is presented.

AIM

Objective of the study was to evaluate the effects of Proteflazid® on the cellular component of the immune system and gestation course in women with HHV infection by using meta-analysis and statistical analysis (based on Student's t-test) of the clinical findings.

MATERIALS AND METHODS

The analysis comprises 5 scientific sources with the results of controlled clinical trials involving 234 pregnant women during the period from 2003 to 2012.

RESULTS

The obtained data prove the efficacy of the preparation Proteflazid ® in treating pregnant women with HHV infection. Administration of the drug Proteflazid® in the treatment of herpesvirus infection in pregnant women contributes to the cellular immunity normalization, which in turn has a positive effect on the course and outcome of pregnancy.

CONCLUSIONS

Therapy with the drug Proteflazid® is etiologically and pathogenetically substantiated, contributes to the normalization of cellular immunity parameters, which, in turn, has a positive effect on the course and outcome of pregnancy.
