Biophys. We are aware that this limited the capture of COVID-19 specific issues as questions were not specifically aimed for COVID-19 patients. JAMA Otolaryngol. Of those, 81 patients belonged to the Intention-To-Treat (ITT) population, comprising randomised patients meeting the key eligibility criteria and having evaluable viral load data on day 1 (baseline) and on day 11 (end of treatment). Patients aged 18 to 60years were eligible to participate if tested positive for SARS-CoV-2 in a Corona test centre by PCR test within 48h prior to inclusion and had to quarantine at home due to instructions of the local health authority. Google Scholar. The most common COVID-19 symptoms (loss of sense of smell, loss of taste, fever, cough, and coryza) improved over time in all 3 treatment groups; and no statistical differences were observed between groups. Article reviewed, edited and finalised the manuscript. J. Infect. Because we get infected with SARS-CoV-2 primarily by breathing it in, a nasal spray might be an easy and efficient way to offer protection against the virus, especially in crowded places. 6). China and India approve nasal COVID vaccines are they a game changer? Open Access funding enabled and organized by Projekt DEAL. Similarly, no clinically relevant differences regarding blood oxygen saturation values were detected between groups (data not shown). Anti.

A summary of study activities is displayed in Table 2. The reduction in virus load over the entire treatment period was clinically meaningful for all three groups (p<0.0001 for both genes).

This trial was conducted at the Department of Otorhinolaryngology, Head and Neck Surgery of the Faculty of Medicine of the University of Cologne, Germany. Of note, in vitro tests carried out prior to the current study did not indicate any interaction between the study products and the PCR reaction (see supplementary PCR data). After treatment, virus load was reduced in all groups (p<0.0001) but was greater in the 0.1% group compared to placebo (p=0.007). Ann. (2021) COVID-19: Azelastine nasal spray reduces virus-load in nasal swabs (CARVIN). To infect a cell, the virus tricks several of that cells proteins, including one called TMPRSS2, to gain entry. Nasal Sprays Could Protect You From Serious COVID-19 Illness Article Objective of the study is to assess the efficacy of Carragelose nasal and throat spray in reducing the rate, severity, and duration of COVID-19 infections. B.R. Symptoms were documented in patient diaries. Trials underway to see if Boots cold remedy can tackle coronavirus The higher viral load value may be explained with the dominance of the alpha (B.1.1.7) SARS-CoV-2 variant during the enrolment phase (Spring 2021, Germany16), which is known to infect the human nasal mucosa more efficiently than the wild-type and has been associated with higher viral load13,14. CAS https://doi.org/10.1007/s10787-021-00847-2 (2021). What scientists say. 62, 50937, Cologne, Germany, German Center for Infection Research (DZIF) Location Bonn-Cologne, Kerpener Str. 48.9% (n=44) of the safety analysis set was male, and the average age was 35.6712.94years. CAS A study led by an expert from The University of Western Australia has found a virus-killing nasal spray could be effective in reducing the spread of COVID-19. Detection of the alpha (B.1.1.7) variant was based on single nucleotide polymorphism analysis for SARS-CoV-2 spike gene mutation N501Y and deletion H69/V70. In addition, patient's quality of life was evaluated by the SF-36 questionnaire, covering 36 items divided into the 8 quality of life domains physical functioning; role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, and general health12. https://doi.org/10.1016/s1081-1206(10)63465-5 (1996). In addition, investigators measured body temperature during V1V7 and oxygen saturation of the blood (using a finger pulse oximeter) on V1, V3, and V5, V6 and V7. Data was analysed primarily exploratively; there was no formal testing of a given hypothesis. However, a rinsing and diluting effect of the placebo formulation would have led to an underestimation of the effect of the use of the azelastine nasal spray. SARS-CoV-2 viral load predicts COVID-19 mortality. Within the subgroup of patients with baseline Ct values below 25, a similar progression of viral load data was observed (Fig. & Ware, J. As a sensitivity analysis based on the SARS-CoV-2 E gene PCR tended to show overall the same effects, PCR results of the E gene are shown in the supplementary material (supplementary Table S3 and S4). 62, 50937, Cologne, Germany, Jens Peter Klussmann,Maria Grosheva,Paula Aguiar de Arago,Henning Morr&Helal Al Saleh, URSAPHARM Arzneimittel GmbH, Industriestrae 35, 66129, Saarbruecken, Germany, Peter Meiser,Michael Flegel,Frank Holzer,Dorothea Gro,Charlotte Steinmetz&Barbara Scherer, Department I of Internal Medicine, Division of Infectious Diseases, University of Cologne, Kerpener Str. The independent 25 variable was the nasal carriage of Bacillus species. Importantly, this scenario corresponds to current COVID-19 treatment regimens (e.g., with monoclonal antibodies or antiviral substances), which are usually started at57days upon start of symptoms but are still efficacious. https://doi.org/10.1016/j.jinf.2021.05.009 (2021). 10, 294. https://doi.org/10.3389/fphar.2019.00294 (2019). It has been suggested that azelastine can inhibit the entry of the SARS-CoV-2 into the nasal mucosa by binding to the ACE2 receptor and also act via binding to the main protease of SARS-CoV-2 and to the host cells sigma-1 receptor, therewith facilitating both viral entry and replication-inhibiting effects6,9. https://doi.org/10.1016/j.bbrc.2020.11.095 (2021). By Dr. Ramya Dwivedi, Ph.D. Jul 19 2021. The current study demonstrated a gradual decrease of patients symptoms and improvements of quality of life. This observational study (HUN-VE: Hungarian Vaccine Effectiveness) estimated vaccine effectiveness against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19-related mortality in 3.7 million . Whether the current data can be extrapolated to other SARS-CoV-2 variants needs to be investigated. Identification of SARS-CoV-2 entry inhibitors among already approved drugs.

Many elderly people as well asindividuals who are immunodeficient for various reasons do not respond to vaccines, and are in the need of other protective measures, said Kalle Saksela, MD, PhD, senior author of the study and a virologist at the University of Helsinki. PubMed Central Samples of day 1 represent pre-treatment baseline samples. Because N-0385 was suitable for use as a nasal spray, researchers used a mouse model that develops severe COVID-19 and gave the mice either N-0385 or control doses of saline in their noses. Rev. Virol. Symptoms were evaluated on a 5-point scale from 1=symptom absent or present very weakly to 5=symptom present very strongly: anosmia, ageusia, cough, sore throat, shortness of breath, coryza, general weakness, headache, aching limb, loss of appetite, pneumonia, nausea, abdominal pain, vomiting, diarrhea, conjunctivitis, rash, lymph node swelling, apathy, somnolence. To obtain With the changing epidemiology of COVID-19 and its impact on our daily lives, there is still an unmet need of COVID-19 therapies treating early infections to prevent progression. Researchers found that for people who regularly used a prescription corticosteroid like Beconase or Nasonex before getting sick with COVID-19, the risk of severe outcomes like hospitalization and death dropped by as much as 25%.
