Effusive–constrictive pericarditis after the second dose of BNT162b2 vaccine (comirnaty): a case report
Abstract Background Whereas effusive-constrictive pericarditis can rarely occur in COVID-19, to date no cases of effusive-constrictive pericarditis related to SARS-CoV2 vaccine have been documented. Case summary A 59-year-old caucasian man presented to our emergency department with effusive-constrictive pericarditis. Symptoms occurred shortly after the second dose of BNT162b2 (Comirnaty) vaccine. No other etiological causes were identified. Guidelines directed therapy for acute pericarditis was implemented, with clinical benefit. Discussion Systemic inflammatory response to COVID-19 can rarely trigger pericarditis. In our case a strong temporal relation between the second dose of BNT162b2 vaccine and symptoms occurrence was documented, indicating a possible rare adverse reaction to the vaccine, similarly to natural infection. Further research is needed to confirm a causal relationship.
