OBJECTIVE: The aim of our study is to determine the risk of coinfection with COVID-19 due to the high prevalence of viral agents in Istanbul in autumn (September, October, and November) and winter (December and January) and to investigate the effects of age, gender, season and clinical features on the development of coinfection with COVID-19. METHODS: In the routine studies of our hospital, COVID-19, reverse transcriptase polymerase chain reaction (RTA kit, Turkiye) and Multiplex PCR Bio-Fire (Bio Merieux Company, France) methods were studied from the nasopharyngeal swab sample and the data were recorded. A total of 400 people with a mean age (7.91±17.80) were included in the study by retrospective scanning. RESULTS: Considering the virus distribution, Respiratory syncytial virus (RSV), COVID-19, rhino/entero virus did not show a significant difference in autumn and winter, while H. metapneumovirus, adeno virus, influenza A significantly higher rates were observed in winter months. Parainfluenza (1, 2, 3, 4) and Corona OC43 were detected at a higher rate in autumn compared to other viruses. Double and triple coinfection rates with other viral agents were high for 2 years and younger. CONCLUSION: The risk of coinfection of COVID-19 with influenza A, RSV, parainfluenza, and rhino/entero virus was found to be higher than other viral agents. Especially in winter, the risk of coinfection with influenza A and COVID-19 increases. In terms of treatment management, coinfection should be investigated in risky patients and influenza a vaccine should be offered to risky groups. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The objective of this study was to understand the observational relationship between adoption of favipiravir into the national COVID-19 treatment protocol and intensive care unit (ICU) admission rates in Istanbul due to COVID-19. METHODS: Data were harvested from the "Public Health Management System-HSYS," which collate centrally the records of all known cases of COVID-19. The total number of cases, numbers admitted to ICU, and number undergoing intubation were compared between 2 time periods: 11th of March, the date on which the first case in Turkey was confirmed, to 30th of March; and March 30, to 10th of April, 5 days after Favipiravir was introduced into the treatment algorithm when, the records were examined. RESULTS: The percentage of patients requiring ICU admission diminished from 24% to 12%, whilst the percentage intubated fell from 77% to 66%. These differences were both statistically significant. CONCLUSION: The addition of favipiravir to the national COVID-19 treatment protocol may explain this rapid decrease in the rate of ICU admissions and intubation. [ABSTRACT FROM AUTHOR]

OBJECTIVE: We aimed to develop a simple, rapid urine test based on the level of foaming that occurs in the urine sample due to the excretion of peptide structures containing amino acids specific to the antigenic structure of COVID-19. In this study, we present the preliminary results of the first clinical study with a newly developed urine foaming test (UFT). METHODS: This study was conducted in a tertiary hospital in Istanbul. After obtaining the approval of the ethics committee, urine samples were taken from three groups of patients whose informed consent was obtained. The groups were created according to the COVID-19 Diagnostic Guide of Ministry of Health: A: outpatients with suspected COVID-19, B: inpatients for follow-up and treatment, C: patients treated in intensive care unit (ICU). Also, 30 healthy volunteers were included as the control group D. Urine samples taken from all groups were delivered to the laboratory. 2.5 ml urine sample was added to the test tube and shaken for 15 seconds and the level of foam formed was visually evaluated according to the color scale. Other data of the patients were obtained from the hospital information management system and the physician caring for the patient. The clinical status, PCR test results, computed tomography (CT), if any, laboratory tests, and UFT results were compared and the level of statistical significance was expressed as p≤0.05 in the 95% confidence intervals (CI). Performance characteristics, such as sensitivity, specificity, positive and negative predictive value of the UFT, were statistically calculated according to the RT-PCR result and/or CT. RESULTS: A statistically significant difference was observed between UFT distributions of the control, outpatient, inpatient and ICU patients (p=0.0001). The results of UFT orange and red in inpatients and ICU patients were statistically significantly higher than in the control and outpatient groups. The diagnostic accuracy of UFT was detected in all group, the pooled sensitivity was 92% (95% CI: 87–95%) and specificity was 89% (95%CI: 80–98%). CONCLUSION: Our preliminary results suggest that the UFT is useful, particularly in predicting the clinical severity of COVID-19. The UFT could be recommended as a point of care test, rapid and non-invasive method in the diagnosis and follow-up of COVID-19.

COVID-19 is a devastating disease, and its control is difficult due to its high transmissibility rate and a long incubation average period (6.4 days). Additionally, more than half of the infected patients were asymptomatic young people or children. The asymptomatic virus transmission is the actual challenge to controlling the disease. Because of limited treatment options, diagnosis techniques have been the first focus all over the world, involving q-RT-PCR as a gold standard, serological tests, point of care studies, or RT-LAMP. Generally, nasopharyngeal, and oropharyngeal samples are preferred clinically as sources. However, alternative sources are being researched, particularly for healthcare professionals who have difficulty taking samples, patients who are afraid of giving samples, and pediatric patients. Herein, physiological saline has been utilized to offer an alternative source besides the swab samples for use in q-RT-PCR. In this study, 212 randomly chosen patients' samples were studied, and we evaluated the concordance and accurate q-RT-PCR results in two different sources, obtained from swab and gargle samples of patients. Herein, physiological saline is utilized, which is widely used medically as a recommended irrigating and wound dressing solution. We obtained in our experiments with this method, the confidence interval determines 74.50% positivity when compared to the routine q-RT-PCR procedure as summarized. In addition, when only the gargle sampling method is studied in low-income countries, the cost of testing for COVID-19 will decrease significantly. Because this method does not require vNAT or VTM transport solution sterile swab sticks as shown. The plastic container with a lid in which the patient can gargle with SF and spit it out is an ideal method for this. Additionally, it provides a great cost-benefit in low-income countries.

In late 2019 on 11th March 2020 a novel coronavirus, SARS-CoV-2 causing Coronavirus disease 2019 (COVID-19) appeared in Wuhan, China and World Health Organisation declared it to have developed pandemic status. Although there are many detection techniques for the disease to control the pandemic such as RT-PCR, serological methods, or fast antigen tests, the actual problem is the prevention of the disease. The nasal cavity and rhino pharynx are key sites of the initial replication of SARS-CoV-2. In this article, the effectiveness of destrovir spray was investigated by creating a mechanical barrier in the nasal and oral mucosa, which are the entry points of the virus into the body, and to destroy the virus that comes into contact with this barrier. In the presented study, quantitation cycle (Cq) and irradiation values (RFU) of 12 different high-positive patients (Cq≤25) after application of both RT-PCR and destrovir spray were determined at different concentrations (10%, 20%, 30%, 40%, and 50%) aimed to evaluate its effectiveness. According to the results obtained by comparing the effectiveness of disinfectant with 70% ethyl alcohol on the 46 patient samples with Cq<20, 46 patient samples with Cq values between 20-25, and 46 patient samples with Cq≥25 including different variants are examined. A total of 138 COVID- 19 patient samples were treated with 5% and 10% ratios of destrovir spray. Its effectiveness on Cq values and RFU was evaluated and it was aimed to compare the effectiveness of this evaluation with 96% ethyl alcohol used in the same samples. [ABSTRACT FROM AUTHOR]
