One of the possibilities of optimizing the therapy of a new coronavirus infection in children with the inclusion of an extract from marshmallow root, chamomile flowers, horsetail grass, walnut leaves, yarrow grass, oak bark and dandelion grass: prospective open comparative cohort study

Abstract

Background. The issue of acute respiratory infections in children remains one of the most urgent. Therefore, in the pandemic due to the new coronavirus SARS-CoV-2, the search for effective treatment regimens for this disease is necessary.
 Aim. To compare the change of clinical symptoms, terms of virus elimination and disease-related economic cost as well as utilization of outpatient healthcare services in children with new coronavirus infection using the herbal medicine Tonsilgon N, oral solution, added to standard therapy.
 Materials and methods. A prospective open comparative cohort study of the effectiveness of coronavirus infection treatment in children using the standard of care alone and the standard of care with Tonsilgon N was conducted. Group 1 children (n=720) received the standard therapy for COVID-19 and Tonsilgon N oral solution for 10 days, and group 2 patients (n=670) only received the standard therapy for COVID-19. Treatment efficacy was evaluated according to the change of clinical symptoms in the observed patients, the results of SARS-CoV-2 coronavirus RNA detection in nasopharyngeal smears by polymerase chain reaction, the utilization of healthcare services, temporary disability of parents, the economic cost of the disease.
 Results. Studied patients of both groups had a typical clinical presentation of mild to moderate severity new coronavirus infection. Fatigue (96.599.7%) and sore throat (93.893.9%) were the most frequent symptoms. Posterior pharynx hyperemia was noted slightly less frequently. Low-grade fever was noted in 85.786.6% of the patients, equally often in patients of both groups. The significant therapeutic effect of the herbal medicine containing extract of marshmallow root, chamomile flowers, horsetail herb, walnut leaf, yarrow herb, oak bark, and dandelion herb includes reducing the time of sore throat relief in 93.2% of main group patients. After 10 days of treatment, sore throat persisted only in 6.8% of group 1 and 68.1% of group 2 patients (p=0.0001). These results indicate that Tonsilgon combined with standard of care is a promising way to improve the quality of life of children with the new coronavirus infection. The addition of Tonsilgon in therapy for new coronavirus infection in children shortens the time of acute inflammation resolution and reduces the duration of inflammatory intoxication. The therapy of new coronavirus infection under the provisional guidelines leads to a reduction in the time for clinical recovery and virus elimination in children and adolescents (p=0.0001) and a decrease in the utilization of outpatient healthcare services are observed: 3/4 of Group 1 patients and 1/2 of Group 2 patients (p=0.0001) applied for medical help twice during the observation period, 14.6% of Group 1 patients and 29.1% of Group 2 parents applied for medical help more than 3 times (p=0.0001). Thus, the direct and indirect economic costs of the disease decreased. The lower economic cost for parents of children in Group 1 was due to less need for medication and a lower reduction in family income due to temporary disability compared to those for parents in Group 2 (p=0.0001). No treatment-related adverse events was reported.
 Conclusion. The above data indicate that Tonsilgon therapy is an affordable way to optimize the treatment of new coronavirus infection in children.
