Background: Mucosal immunity plays a major role not only in the prevention but probably also in the outcome of COVID-19. An enhanced production of secretory Immunoglobulin A (sIgA) might contribute to the activation of the immune response mechanisms.
Objective: To assess the levels of sIgA produced by epithelial cells in the nasal and pharyngeal mucosa and those measured in salivary gland secretions and to study the course of COVID-19 following the intranasal or subcutaneous administration of a bacteria-based immuno-stimulant agent.
Materials and methods: This study included 69 patients aged between 18 and 60, who had moderate COVID-19 infection. They were divided into two groups: Group 1 (control group) included 39 patients who received only background therapy, and Group 2 was made up of 30 patients who received b.. View More»
