Rhabdomyolysis Following Recovery from Severe COVID-19: A Case Report.

Am J Case Rep 2021 May 8;22:e931616. Epub 2021 May 8.

Oregon Health & Science University, Portland, OR, USA.

BACKGROUND Rhabdomyolysis occurs when muscle injury leads to the release of muscle cell constituents into circulation, often leading to significant systemic complications. There are many causes of rhabdomyolysis, and the etiology is often multifactorial or unclear. Current data suggest that acute COVID-19 may cause muscle injury that can lead to rhabdomyolysis, particularly in cases of severe illness requiring prolonged hospitalization; however, data on the long-term effects of COVID-19 on the musculoskeletal system are lacking.
