Clinical narrative: pericarditis; This literature-non-study case was reported in a literature article and describes the occurrence of PERICARDITIS (pericarditis) in a 49-year-old female patient who received SPIKEVAX NOS (SPIKEVAX NOS) for COVID-19 prophylaxis.   LITERATURE REFERENCE:     Concurrent medical conditions included Diabetes.   On an unknown date, the patient received fifth dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) 1 dosage form. On an unknown date, received fourth dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) dosage was changed to 1 dosage form, third dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) dosage was changed to 1 dosage form, second dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) dosage was changed to 1 dosage form and first dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) dosage was changed to 1 dosage form. On an unknown date,  after starting SPIKEVAX NOS (SPIKEVAX NOS), the patient experienced PERICARDITIS (pericarditis) (seriousness criterion medically significant). The patient was treated with Colchicine at an unspecified dose and frequency and Rilonacept at an unspecified dose and frequency. At the time of the report, PERICARDITIS (pericarditis) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Echocardiogram: Small effusion. On an unknown date, Ejection fraction: Preserved. On an unknown date, Electrocardiogram: normal value (NV). On an unknown date, Magnetic resonance imaging heart: Circumferential pericardial late gadolinium enhancement (LGE). On an unknown date, SARS-CoV-2 test: (Negative) COVID-19 testing was performed upon admission. On an unknown date, White blood cell count (4.00-11.00 thousand per microlitre): 7.6 thousand per microlitre.     For SPIKEVAX NOS (SPIKEVAX NOS) (Unknown), the reporter did not provide any causality assessments.   This case referred to case no 8 from table no 1 of the article.  Concomitant medications were not reported.  In this study patients presented with recurrent or incessant, difficult-to-treat pericarditis following SARS-CoV2 vaccination between October 2021 and January 2025. All patients had a clear temporal relationship between vaccination and the onset of symptoms of pericarditis, and all were negative for acute SARS-CoV2 infection.  Patient had chest pain as clinical presentation.  It was her first episode which was recurrent, and it recurred once.  Patient had no history of COVID-19, C-reactive protein (CRP) was not done.  Patient was treated with corticosteroids for 7 months.  Patient had emergency department (ED) visit once.   Times from latest recurrence was 17 months.  Corticosteroids were required in all eight patients due to persistent or worsening symptoms. Corticosteroids were tapered off gradually, two suffered side effects and four patients experienced a recurrence during tapering. Two experienced minor flares when the interval between the rilonacept dose was increased to every 3 and 4 weeks, with a resolution of symptoms when resuming weekly injections. All six (100 %) continue to be on weekly treatment at this time.   Author concluded that pericarditis following SARS-CoV-2 vaccination can evolve into a recurrent, difficult-to-manage inflammatory condition. Effective treatment may require IL-1 blockade to disrupt the autoinflammatory cycle. Prompt recognition and early escalation of therapy are essential to reduce morbidity and prevent complications.
