One patient (n.4) among the vaccinated group displayed feature of myocarditis (Figure 4B) that was most likely associated with cirrhotic cardiomyopathy, as supported by the alcoholic encephalopathy highlighted at the clinical and histological levels [19]; one other patient (n.2) showed myocardial infiltration of CD68- and CD45-positive cells for acute and chronic ischemic cardiomyopathy (Figure 4B). Here, PTPRC is linked to myocarditis.
