Clinical narrative: Thrombotic thrombocytopenic purpura; This literature-non-study case was reported in a literature article and describes the occurrence of THROMBOTIC THROMBOCYTOPENIC PURPURA (Thrombotic thrombocytopenic purpura) in an elderly female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination.       Concurrent medical conditions included Chronic myeloid leukaemia (Patient has a history of chronic myeloid leukaemia (CML), diagnosed 5 years prior. CML is being treated with dasatinib, and patient is currently in molecular remission.) since 2017, Hyperlipidemia and Tobacco user. Concomitant products included DASATINIB for Chronic myeloid leukaemia.   On an unknown date, the patient received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form and first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date,  after starting mRNA-1273 (Moderna COVID-19 Vaccine), the patient experienced THROMBOTIC THROMBOCYTOPENIC PURPURA (Thrombotic thrombocytopenic purpura) (seriousness criteria hospitalization and medically significant). The patient was treated with METHYLPREDNISOLONE for Thrombotic thrombocytopenic purpura, at a dose of 250 milligram every six hours.

For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered THROMBOTIC THROMBOCYTOPENIC PURPURA (Thrombotic thrombocytopenic purpura) to be related.    Patient began to develop symptoms 2 days after receiving her Moderna booster vaccine and presented to urgent care with an 8 day history of fatigue, generalised weakness, headache, abdominal pain and haematuria.  Patient was asymptomatic following her first 2 Moderna vaccines. There were no recent medication changes.  Pathologist review of the blood sample showed marked thrombocytopenia,  worrisome for thrombotic microangiopathy. Therefore, further workup was ordered stat.  Genetic testing for congenital TTP was not completed on the patient.  Treatment also included therapeutic plasma exchange which was ordered and initiated within 24 hours of admission after a central line was placed by interventional radiology. She underwent daily therapeutic plasma exchange with 100% plasma volume replacement with 4000 mL of fresh frozen plasma. She completed daily exchanges for 4 days, and then these were stopped.  Three days after treatment was initiated with steroids and plasmapheresis, the diagnosis of TTP was confirmed  The patient recovered well and continues to follow with her haematologist.  Patient had laboratory findings suggesting TTP including: severe thrombocytopenia, microangiopathic anaemia with elevated haemolytic markers, the presence of schistocytes in peripheral blood, and low ADAMTS13 activity, along with typical clinical symptoms. Her PLASMIC score was 7 indicating severe disease, and she also had a negative PF4 antibody arguing against VITT. As completed in our patient, urgent plasmapheresis is the cornerstone of TTP management and should be implemented at the time of suspicion.  The temporal relationship to receiving the Moderna vaccine and development of TTP makes the vaccine more likely the culprit. However, there is no way to prove the vaccine was the cause of TTP and a causal association cannot be established based on a single case.
