[Research progress of relationship in long-novel coronavirus syndrome and sarcopenia].

ABSTRACT

At present, the major public health challenges caused by novel coronavirus infection have gradually subside. However, a large number of people are still suffering from long-novel coronavirus syndrome or post-novel coronavirus syndrome. The clinical manifestations of long coronavirus syndrome are related to multiple systems, such as respiratory, circulatory, nervous, digestive and musculoskeletal systems, with various long-term persistent symptoms after novel coronavirus infection. At the same time, the infection of the novel coronavirus is an important cause of frailty and sarcopenia in the elderly population. However, at present, the scholars have not paid enough attention to the skeletal muscle weakness caused by the novel coronavirus. Therefore, this paper focuses on the long-novel coronavirus syndrome and sarcopenia to explore the pathological mechanism of skeletal muscle attenuation caused by the SARS-CoV-2 mediated "cytokine storm", mitochondrial damage, hypoxia state and other links,so as to raise the attention of clinical and academic researchers and improve the clinical strategy of frailty and sarcopenia after novel coronavirus infection.
