CDC Split Type:

Write-up: Vaccine administered at outside facility. Patient is a 16 yo girl, admitted on 4/19 with myocarditis, s/p IVIG (4/19) after presenting with progressive new onset chest pain. She was in usual state of health up until 2 days ago when she started developing body aches, and chest pain. Patient received her 2nd Pfizer COVID vaccine last week (4/15). No known history of COVID infection. Parents brought her to the ED yesterday after she complained of dizziness, SOB, chest pain, and had a near syncopal event. EKG showed non-specific ST abnormalities with labs showing elevated troponin, mildly elevated CRP, normal CXR, negative COVID PCR. Denies fever, GI symptoms, GU symptoms, headache, rash. Once transferred to our PICU, she was worked up for myocarditis vs MIS-C. Troponin has been trended q6 and is trending up (now 11). Of note, there have been no fevers. Patient is a 16 yo girl, s/p admission (4/19-4/23/21) with myocarditis, s/p IVIG (4/19), has now been readmitted on 5/10 with myocarditis after presenting with headache and neck pain for 2 days. Following discharge from the PICU on 4/23, patient states that symptoms have lingered (low grade fevers, feeling tired, on and off chest pain). After developing a progressive headache and neck pain, she came back to the ER for re-evaluation. Upon readmission, her troponin was elevated (2.06 on 5/10). Her CBC and CMP were reassuring. Blood culture collected on 5/11 and urine culture collected on 5/10. ID consulted for workup.

Diagnostic Lab Data: Unsure exact procedures and numbers. Multiple EKGs and blood enzyme laboratory tests throughout 5/15 and 5/16 indicating pericarditis and mild myocarditis throughout stay. Enzymes spiked at around 3AM 5/16.
CDC Split Type:

Write-up: Typical side effect symptoms experienced and cleared within 24 hours. Same symptoms returned (chills, low fever, heavy sweating, tense breathing) approx. 60 hours later along with severe aching chest pain. All symptoms resolved by next morning besides chest pain, which was severe enough to warrant emergency room admission about 72 hours after vaccination. Admitted to hospital overnight with an episode of palpitations around 6pm on the first night, being given motrin and colchicine throughout stay. Pain somewhat resolved and was discharged aprox. 100 hours after vaccination. Continued use of ibuprofen and colchicine in weeks following as pain slowly resolves.
