RESUMEN
Introduction/Aim: We conducted an open label, randomized, controlled trial to assess whether fluvoxamine combined with bromhexine, given during mild to moderate SARS-CoV-2 illness, prevented clinical deterioration due to their proposed immune modulatory effects. Method(s): Participants had confirmed SARS-CoV-2 infection, experiencing mild to moderate symptoms and oxygen saturation of >=92%. Participants were randomly assigned to receive fluvoxamine (100 mg days 1 and 2, followed by 150 mg daily till day 14) with bromhexine (FLU/BRO) (16 mg daily till day 10) or favipiravir alone (FAV) (3600 mg day 1 followed by 1600 mg daily till day 5). Primary outcome was clinical deterioration within 30 days of randomization defined as shortness of breath or hospitalization for shortness of breath or pneumonia and oxygen saturation >=92%, on room air or need for supplemental oxygen to achieve oxygen saturation of >=92%. Result(s): 158 participants were randomized (average age 50 years (range 18-68 years);68 [43%] women), and 142 (89%) completed the trial. 0/78 participants experience clinical deterioration with FLU/BRO and 18/64 patients with FAV. TNF-alpha, IL-6 IL-8 and IL-1beta levels were significantly (p < 0.005) reduced with FLU/BRO compared to FAV at day 3, 5, 7 and 14. 0/78 participants had long COVID symptoms with FLU/BRO compared to 32/64 (50%) with FAV (p < 0.005). One serious (clumsiness or unsteadiness) and 10 other adverse events were reported with FLU/BRO compared to 5 serious and 12 other adverse events with FAV. Conclusion(s): Results suggest there was significantly less clinical deterioration in symptomatic COVID-19 participants treated with FLU/BRO.
RESUMEN
Introduction/Aim: Coronavirus disease 2019 (COVID-19) is a novel viral infection that can cause severe pneumonia and acute respiratory failure;however, the mechanism of disease progression is still unclear. The aim of this study is to evaluate inflammatory cells in the lung by analysing cell populations of bronchial aspirates of COVID-19 pneumonia. Method(s): Eligible cases were diagnosed as COVID-19, confirmed by SARS-CoV-2 PCR. All cases had developed severe COVID-19 pneumonia and undergone invasive positive pressure ventilation for the treatment of respiratory failure. Bronchial aspirates were collected during endotracheal intubation, and SARS-CoV-2 PCR was done. The populations of obtained cells from bronchial aspirates were examined by Giemsa staining and immunohistochemical staining of CD3, CD4, CD8, CD20 and CD68 antigens. Bronchial aspirates were cultured to confirm respiratory bacterial co-infections. Result(s): A total of 14 cases (median age 70;eleven male and three female) were enrolled in this study. Their bronchial aspirates were all positive for SARS-CoV-2 PCR. Bacterial co-infections were developed in 10 cases, including 6 cases of pneumonia/respiratory tract infection, 2 cases of sepsis, and 2 cases of urinary tract infection. Cell populations of bronchial aspirates with or without bacterial co-infections were as follows: neutrophils 33.0% vs. 21.5%;CD3+ mononuclear cells (MNCs) 2.5% vs. 5.8%;CD4+ MNCs 4.6% vs. 3.4%;CD8+ MNCs 3.5% vs. 5.2%;CD20+ MNCs 0.2% vs. 0.1%;CD68+ MNCs 39.7% vs. 38.8%, respectively. Conclusion(s): CD68 antigen is mainly expressed in monocytes/macrophages. CD68+ MNCs were dominant in bronchial aspirates of the cases with severe COVID-19 pneumonia. Our data suggests that CD68+ MNCs, presumably macrophages, would play an essential role during the innate immune response to acute SARS-CoV-2 infection in the lung.
RESUMEN
Common cold and influenza are often complicated by pneumococcal pneumonia, but the complication whereas pneumococcal pneumonia complicating COVID-19 is not common. Both influenza and COVID-19 are respiratory viral infections, and their pathogenesis depends on the host immune response. Therefore, clinically, accurate pathogen diagnosis in the early stage of the clinical course for the purpose of formulating an appropriate treatment plan may contribute to improvement of the patient prognosis. Clinical characteristics of COVID-19 in clinical manifestations, epidemiological history, laboratory findings and radiological findings, some of which were different and some of which were similar from influenza or any other common cold. We would like to emphasize the importance of researching the mechanism of pneumonia induced from common cold, influenza, COVID-19 and any other respiratory viral infection.

RESUMEN
Iran was one of the first countries that was severely affected by the COVID-19 outbreak in the Middle East in February of 2020. What is unique about Iran is that religious leaders from the early stages have been involved with debates concerning its cause, preventive measures, and moral significance. Relying on textual analyses of media coverage, herein we examine religious debates in Iran that are increasingly gaining public attention amid the pandemic. Our analyses illuminate the styles of reasoning used by religious leaders to situate their understandings of the pandemic that are principally organized through the language of science. Our findings include that religious leaders are receptive to modern science, but not unquestionably. The status, application, and development of modem science is contingently shaped by the discourses and practices of Islam that religious leaders find compelling based on what they regard as a proper understanding of Islam and Islamic medicine.

RESUMEN
Aim: We present the study protocol of a multicenter, retrospective observational study that aims to investigate the efficacy of the actual treatment (the efficacy of conventional and Kampo medicines) of patients with mild to moderate or suspected coronavirus disease (COVID-19). Methods: This study is designed as a multicenter, retrospective observational study. Outpatients and inpatients will be recruited from Japanese hospitals. The inclusion criteria are as follows: having or suspected to have COVID-19, mild to moderate COVID-19, symptomatic, ≥20 years of age, male or female, able to communicate in Japanese, and treated with conventional and Kampo medicine. The exclusion criteria are: unable to provide informed consent due to dementia, psychosis, or psychiatric symptoms, severe COVID-19, or determined unsuitable for this study. The sample size is set at 1000, as this number of people can be treated at the collaborating medical institutions during the study period. Results: The main outcome is the number of days without fever, with a body temperature of less than 37°C. The secondary outcome is set at common cold-like symptoms other than fever (fatigue, cough, shortness of breath, sputum, diarrhea) and severity of illness and hospitalization up to 14 days after the visit. Trial registration: The trial was registered in the University Hospital Medical Information Network (Reservation No. UMIN000041301) on August 4, 2020. Conclusion: Our study will explore the contribution of conventional and Kampo medicine in the treatment of patients with mild and moderate COVID-19.
