The association between troponin positivity and adverse clinical outcomes, echocardiographic findings, and mortality in hospitalized patients with COVID-19.

Background: Troponin-I elevation during a COVID-19 infection is likely due to multiple factors. Few studies have investigated the relationship between troponin levels and echocardiographic variables in patients with COVID-19. Our study aimed to evaluate the clinical and paraclinical effects-including echocardiographic findings-of COVID-19 on myocardial injury, as indicated by elevated troponin levels, and to assess its potential impact on in-hospital and three-month outcomes in hospitalized COVID-19 patients.

New-onset chronic inflammatory demyelinating polyradiculoneuropathy after COVID-19 infection: a case report.

Introduction And Importance: SARS-CoV-2 infection, besides respiratory symptoms, as cardinal manifestation, may present with neurological involvement. Immune-mediated polyradiculoneuropathy is one of the important neurological complications manifested by COVID-19 mainly includes Guillain-Barré syndrome (GBS), treatment-related fluctuation of GBS, and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Also, there are several reports of COVID-19 vaccine-related GBS and CIDP.
