Multisystem Inflammatory Syndrome In Children at Sohag University Hospital

Study Overview
=================
Brief Summary
-----------------
Since its initial description in December 2019 in Wuhan , China, Corona virus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), has rapidly evolved into a worldwide pandemic affecting millions of lives . Unlike adults, the vast majority of children with COVID-19 have mild symptoms. However, there are children who have significant respiratory disease, and some children may develop a hyper inflammatory response similar to what has been observed in adults with COVID-19. Furthermore, in late April 2020, reports emerged of children with a different clinical syndrome resembling Kawasaki disease (KD) and toxic shock syndrome; these patients frequently had evidence of prior exposure to SARS-CoV-2. The pathophysiology of MIS-C: Is unclear ,but it appears to be a consequence of a exacerbated immune system response or maladaptive response of the host .After the virus enters the human cells, the first line of defense against infection should be a quick and well-coordinated immune response ;however, when this mechanism is unregulated and excessive ,hyper inflammation can occur. Cytokines that play an important role in inducing immunity and immunopathology during infections in excess can cause the clinical syndrome known as cytokine storm. The inflammatory response caused by SARS-CoV-2appears to be the major cause of mortality in infected patients . The infection of dendritic cells or macrophages by SARS-CoV-2 induces the production of low levels of antiviral cytokines and increases the production of inflammatory cytokines (tumor necrosis factor[TNF], interleukin[IL]-1, IL-6,and interferon ).
