Background/aim: SARS-CoV-2 disease was announced as a pandemic by The World Health Organization in early 2020. It is still threatening the world population. Here, we aimed to produce hyperimmune sera that contain immunoglobulin G and F(ab')2 fragments sourced from horse antibodies as an urgent response to the pandemic. Materials and methods: SARS-CoV-2 was produced and inactivated with three different methods [formaldehyde (FA), formaldehyde, and binary ethylene amine (FA + BEI), and heat treatment]. After in vitro inactivation control, immunogens were mixed with Freund's adjuvant, thereafter horses (n: 2 for FA, 4 for FA + BEI, 2 for heat inactivation) and …

Turkish Journal of Medical Sciences

Although we have enough and cumulative information about acute effects of COVID-19, our knowledge is extremely limited about long-term consequences of COVID-19, in terms of its impacts and burdens on patients, families, and the health system. Considering the underlying pathophysiological mechanisms affecting all of the organ systems in critically ill COVID-19 patients who are admitted to intensive care units, the development of post-intensive care syndrome is inevitable. This situation brings along the development of long-COVID. These patients should be followed regarding cognitive, physical, and psychiatric aspects and necessary specialist referrals should be carried out. In this article, we are presenting …

Background/aim: Coronavirus 2019 disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a pandemic infectious disease that causes morbidity and mortality. As a result of high mortality rate among the severe COVID-19 patients, the early detection of the disease stage and early effective interventions are very important in reducing mortality. Hence, it is important to differentiate severe and nonsevere cases from each other. To date, there are no proven diagnostic or prognostic parameters that can be used in this manner. Due to the expensive and not easily accessible tests that are performed for COVID-19, researchers are investigating …
