Aim. In this study we evaluated the effects of Riamilovir on SARS-CoV-2 viral shedding and on admission duration in patients with moderate COVID-19. Materials and methods. We have used data from 69 health records of patients with moderate severe PCR confirmed SARS-CoV-2 infection. Control group included 34 patients treated with off-label riamilovir 1250 mg per day for 5 days (250 mg 5 times a day), comparison groups 35 patients, who received ribavirin and umifenovir 800 mg a day for 5 days. The antiviral therapy was administered within 72 hours from the onset of the disease. The primary endpoints were elimination of virus in oropharyngeal and nasopharyngeal swabs on 7 day of admission and discharge from the hospital by 14 day. Results. Patients assigned to riamilovir had significantly shorter time to clinical improvement as well as increased PCR negative rate by day 7. Conclusion. Yearly administration of riamilovir as opposed to the umifenovir and ribavirin in therapy of moderate SARS-CoV-2 infection was associated with significant shorter time to clinical improvement by 14 day of hospitalization. PCR negative rate by 7 days of hospitalization is significantly more likely in riamilovir group.
Aim. The study evaluates clinical effectiveness and safety of etiotropic antiviral medications with a direct mechanism of action (Riamilovir, Ribavirin, Umifenovir) for the treatment of moderate SARS-CoV-2 infection in adults. Materials and methods. The study used the data from 59 health records of patients with moderate PCR-confirmed SARS-CoV-2 infection. Control group included 29 patients treated with 1250 mg Riamilovir off-label per day for 5 days (250 mg 5 times a day), comparison group consisted of 30 patients, who received 800 mg Ribavirin and Umifenovir per day for 5 days. The effectiveness of the medications was assessed by the duration and severity of general infectious and respiratory syndromes, anosmia and ageusia, as well as the oxygen content in the blood, the timing of SARS-COV-2 virus elimination from the body according to the results of control studies of nasopharyngeal swabs using the PCR method and dynamics of blood tests results. Results. A statistically significant decrease in the duration of fever, cough, and anosmia and a more rapid elimination of the virus from the body were noted in the group of patients receiving Riamilovir. Decreased levels of non-specific inflammatory markers in blood serum, as well as normal values of liver enzymes were observed in control group during therapy, as opposed to the comparison group. No serious adverse events were noted when using the medication. Conclusion. Nucleoside analogue medication Riamilovir showed good effectiveness and safety profile in adult patients with moderate SARS-CoV-2 infection.
Аbstract. We consider the possibility of optimizing the diagnosis of infection caused by SARS-CoV-2 using polymerase chain reaction in a multi-specialty hospital, repurposed for the treatment of COVID-19 patients, using the example Of the military medical Academy named after S.M. Kirov. The analysis of scientific publications selected in accordance with the purpose of the study, analyzed data from 218 samples of polymerase chain reaction in patients with COVID-19, who were in the clinics Of the military medical Academy named after Sm. Time intervals were established depending on the clinical forms and severity of the infectious process, in which the probability of a positive and negative result of a polymerase chain reaction to SARS-CoV-2 RNA was maximum and minimum. It was shown that during the examination and treatment, molecular biological diagnostics were performed excessively (4 times in more than 50% of patients) and in 97,3% of patients unreasonably early (8,50,4 days). At the same time, the highest frequency of negative results of polymerase chain reaction to SARS-CoV-2 RNA was observed in the period from 9 to 10 and from 12 to 14 days, while it depended on the clinical form and severity of the infectious process. In this regard, the volume diagnosis using polymerase chain reaction should be reduced and to conduct research when entering the hospital, on the 9th-10th day (in patients inapparently forms and acute respiratory diseases, lung flow) and 12-14 days before discharge in patients with moderate and severe course of the infectious process.
Aim. To evaluate clinical efficacy of nucleoside analogues in therapy of moderate COVID-19 in in-patients. Materials and methods. Retrospective processing of 108 completed clinical cases with moderate novel coronavirus disease was carried out for the period 20202021. The duration of the disease at the time of admission did not exceed three days. Experimental group consisted of 53 patients who, in addition to standard therapy, were prescribed off-label riamilovir at a daily dosage of 1250 mg for 5 days by the decision of the medical commission. Comparison group included 55 patients who received a combination of umifenovir and ribavirin as antiviral therapy for 5 days. The duration of the main clinical manifestations of the disease, the indicators of clinical and biochemical blood tests, results of the SARS-CoV-2 virus RNA study using the nucleic acid amplification method (NAAT diagnostics). Results. Significantly faster achievement of clinical improvement in the group of patients treated with riamilovir was shown, as well as faster sanitation from SARS-CoV-2 virus based on the results of etiological testing. Conclusion. The use of riamilovir for the treatment of patients with moderate novel coronavirus infection (COVID-19) resulted in a significant reduction of general infectious syndromes and respiratory symptoms. Patients from the experimental group significantly faster achieved clinical recovery and sanitation from the pathogen according to the results of NAAT diagnostics.
Relevance. Despite the implementation of measures to reduce morbidity and mortality among medical workers who are in contact with patients hospitalized for a new coronavirus infection caused by , their level remains high today. Given the difficulty of achieving the required number of vaccinated to form collective immunity, the issue of finding additional drug-based ways to prevent COVID-19, especially in risk groups, becomes urgent. Aims. To evaluate the effect of azoximer bromide
