Multisystemic inflammatory syndrome in a young adult after SARS‐CoV‐2 infection: Case report.

Recent studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may precede the appearance of dysregulated immune responses, adopting the form of the multisystemic inflammatory syndrome in adults (MIS-A), as previously described in children (MIS-C).1 In this paper is presented the case of a 24-year-old Hispanic woman with a record of persistent positivity for lupus anticoagulant at moderate titers, without previous thrombotic or obstetric events, that was admitted to the hospital after 4 days of fever, headache, odynophagia, bilateral cervical painful lymphadenopathies, abdominal pain, nausea, vomiting, and diffuse exanthema. However, after having reasonably ruled out infectious and autoimmune pathology with normal laboratory, microbiologic, and imaging tests, and considering the recent SARS-CoV-2 infection, MSI-A was suspected and treated with a 2 mg/kg single dose of intravenous immunoglobulins and 1 mg/kg/day prednisone. The patient had experienced a recent SARS-CoV-2 infection, properly confirmed by a polymerase chain reaction (PCR) swab test 20 days before the admission. [Extracted from the article]
