Clinical narrative: Myopericarditis with hemorrhagic pericardial effusion; Myopericarditis; chills again; intermittent fever; back pain; This is a literature report.  A 74-year-old male patient received BNT162b2 (BNT162B2), as dose 1, single (Batch/Lot number: unknown) and as dose 2, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "alcoholic cirrhosis" (unspecified if ongoing); "hypertension" (unspecified if ongoing); "hospitalization" (unspecified if ongoing). The patient's concomitant medications were not reported. The following information was reported: PERICARDIAL EFFUSION (hospitalization, medically significant), 2 weeks after the suspect product(s) administration, outcome "recovered", described as "Myopericarditis with hemorrhagic pericardial effusion"; MYOPERICARDITIS (hospitalization, medically significant), 2 weeks after the suspect product(s) administration, outcome "recovered"; CHILLS (hospitalization), outcome "recovered", described as "chills again"; PYREXIA (hospitalization), outcome "recovered", described as "intermittent fever"; BACK PAIN (hospitalization), outcome "recovered". The patient underwent the following laboratory tests and procedures: Angiotensin converting enzyme: Negative; Antibody test: Negative; Antineutrophil cytoplasmic antibody: Negative; Bacterial test: Negative; Blood pressure measurement: 110/62 mmHg; Body temperature: 36.1 Centigrade, notes: degree celcius; Cardiopulmonary exercise test: normal; Cardiovascular examination: normal; Chest X-ray: clear lungs with no abnormality; Computerised tomogram abdomen: ruled out tumor masses; Computerised tomogram pelvis: ruled out tumor masses; Computerised tomogram thorax: ruled out tumor masses; it revealed new pericardial effusion; C-reactive protein: 247 mg/l; Cytology: did not show malignant cells; Echocardiogram: showed a large circumferential pericardial, notes: effusion without tamponade physiology; showed a small precordial effusion.; Electrocardiogram: new-onset atrial fibrillation and his chest X-ray, notes: (CXR) confirmed clear lungs with no abnormality; Epstein-Barr virus antibody: negative; Fungal test: negative; Gene sequencing: negative; Gram stain: Negative; Heart rate: 87, notes: beats/min; Hepatitis C virus core antigen: negative; Herpes virus test: negative; HIV test: negative; Imaging procedure: revealed no signs of active inflammation but it, notes: did show a small area of epicardial enhancement characteristic of prior myocarditis; Inflammatory marker test: elevated; Autoimmunity study: negative; revealed 201,000 red blood cells per mm^3, 2375 ce, notes: cells per mm 3 with 67% lymphocytes, negative Gram stain, and acid-fast bacilli; Negative; laboratory workup: showed mild leukocytosis; Lymphocyte count: 67 %; Magnetic resonance imaging: done to exclude possible infiltrative etiology of, notes: myopericarditis; Mycobacterium test: negative; Myocardial necrosis marker: normal; Nasopharyngeal swab: Negative; Oxygen saturation: 90, notes: percent on ambient air; Parvovirus B19 test: negative; Red blood cell count: 201000 /mm3, notes: per mm3; Respiratory rate: 16, notes: breaths/min; Serology test: negative; White blood cell agglutination present: 15000 /mm3, notes: cells/mm3. Therapeutic measures were taken as a result of pericardial effusion, myopericarditis, chills, pyrexia, back pain. Clinical course: He was given five doses of prednisone, but he did not show any improvements. The patient had no known COVID-19 exposures, history of recent viral illness, or other known risk factors. The patient was doing well for a week after discharge from the hospital until he started to have back pain, intermittent fever, and chills again. He was admitted again to the hospital, and repeated thoracic echocardiogram showed a small precordial effusion. Therefore, treatment with ibuprofen 600 mg three times a day and colchicine 0.5 mg twice a day was initiated. On a four-week follow-up, the patient reported a complete relief of chest pain. Both colchicine and ibuprofen were thus discontinued.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: Based on the known safety profile and Limited information in the case report a casual association between reported events and the suspect drug BNT162B2 cannot be excluded. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events.
