Two Adults With Multisystem Inflammatory Syndrome Post-COVID-19 in a Lebanese Hospital: A Case Report

COVID-19 is a respiratory illness with multiple extra-pulmonary complications. The multisystem inflammatory syndrome (MIS) is one of its complications that usually affects children and is known as MIS-C, but several cases have been reported in adults, symbolized by MIS-A. Thus, the Centers for Disease Control and Prevention (CDC) developed a working case definition of MIS-A, which includes several criteria. Here we report two cases of adult male patients with clinical and laboratory symptoms consistent with MIS-A. Case one patient presented at a late stage after two weeks post the onset of symptoms. His health deteriorated rapidly, and eventually, he passed away. However, the second patient presented a few days after the symptoms' onset and took a course of steroids. He was discharged home.
