Purpuric rash; Accelerated hypertension; Systolic congestive heart failure exacerbation; nausea; Generalized non-itchy, non-painful rash a day after receiving the vaccine; Thrombocytopenia; few loose stools; Fever; Chills; This literature-non-study case was reported in a literature article and describes the occurrence of RASH (Generalized non-itchy, non-painful rash a day after receiving the vaccine), THROMBOCYTOPENIA (Thrombocytopenia), PURPURA (Purpuric rash), ACCELERATED HYPERTENSION (Accelerated hypertension), ACUTE LEFT VENTRICULAR FAILURE (Systolic congestive heart failure exacerbation) and NAUSEA (nausea) in a 60-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.    Purpuric Rash and Thrombocytopenia After the mRNA-1273 (Moderna) COVID-19 Vaccine. Cureus. 2021;13:4     Previously administered products included for Viral hepatitis C: Interferon. Concurrent medical conditions included Viral hepatitis C, Chronic kidney disease (Stage 4, with a baseline creatinine of 3 mg/dl.), Uncontrolled hypertension, Systolic heart failure (Ejection fraction of 35%.) and Liver cirrhosis.    On an unknown date, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, the patient experienced RASH (Generalized non-itchy, non-painful rash a day after receiving the vaccine) (seriousness criterion hospitalization), THROMBOCYTOPENIA (Thrombocytopenia) (seriousness criteria hospitalization prolonged and medically significant), PURPURA (Purpuric rash) (seriousness criterion hospitalization), ACCELERATED HYPERTENSION (Accelerated hypertension) (seriousness criterion hospitalization), ACUTE LEFT VENTRICULAR FAILURE (Systolic congestive heart failure exacerbation) (seriousness criterion hospitalization), NAUSEA (nausea) (seriousness criterion hospitalization), DIARRHOEA (few loose stools), PYREXIA (Fever) and CHILLS (Chills). The patient was hospitalized for 3 days due to ACCELERATED HYPERTENSION, ACUTE LEFT VENTRICULAR FAILURE, NAUSEA, PURPURA, RASH and THROMBOCYTOPENIA. At the time of the report, RASH (Generalized non-itchy, non-painful rash a day after receiving the vaccine), THROMBOCYTOPENIA (Thrombocytopenia), PURPURA (Purpuric rash), ACCELERATED HYPERTENSION (Accelerated hypertension), ACUTE LEFT VENTRICULAR FAILURE (Systolic congestive heart failure exacerbation), NAUSEA (nausea), DIARRHOEA (few loose stools) and CHILLS (Chills) outcome was unknown and PYREXIA (Fever) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In February 2021, SARS-CoV-2 test: negative (Negative) Negative COVID-19 test. In March 2021, Alanine aminotransferase: 90 (abnormal) 90 U/L. In March 2021, Aspartate aminotransferase: 196 (abnormal) 196 U/L. In March 2021, Bilirubin conjugated: 5 (abnormal) 05 mg/dl. In March 2021, Blood albumin: 1.9 (abnormal) 1.9 gm/dl. In March 2021, Blood alkaline phosphatase: 216 (abnormal) 216 U/L. In March 2021, Blood creatinine: 3.2 (Inconclusive) 3.2 mg/dl. In March 2021, Blood lactate dehydrogenase (122-222): 381 (High) high. In March 2021, Chest X-ray: abnormal (abnormal) Findings consistent with pulmonary edema.. In March 2021, Glomerular filtration rate: 19 (Low) eGFR - 19. In March 2021, International normalised ratio: 1.13 (Inconclusive) INR - 1.13. In March 2021, Platelet count: 84000 (Low) 84000/uL. In March 2021, Serum ferritin (24-336): 2400 (High) 2400 mg/ml. In March 2021, Ultrasound liver: abnormal (abnormal) Ultrasound of the liver confirmed liver cirrhosis..     The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown Route) was unknown.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown Route), the reporter considered THROMBOCYTOPENIA (Thrombocytopenia) and PURPURA (Purpuric rash) to be possibly related. No further causality assessments were provided for RASH (Generalized non-itchy, non-painful rash a day after receiving the vaccine), ACCELERATED HYPERTENSION (Accelerated hypertension), ACUTE LEFT VENTRICULAR FAILURE (Systolic congestive heart failure exacerbation), NAUSEA (nausea), DIARRHOEA (few loose stools), PYREXIA (Fever) and CHILLS (Chills).    Concomitant medications were not provided.  Hepatitis panel showed a heavy viral load of more than 11 (no reference range was provided).  Per reporter, on presentation to the emergency room the patient was afebrile, had a blood pressure 183/106 mmHg, pulse rate of 82 per minute and oxygen saturation of 96% on room air.  Treatment included anti-hypertensives and intravenous diuretics. On day 3 of hospitalization, patient left the hospital against medical advice.  Based on reporter's causality, the event purpuric rash is assessed as possible related to mRNA-1273. However, the reporter also indicated it could have been precipitated by the underlying thrombocytopenia, liver cirrhosis and Hepatitis C infection. Very limited information regarding the other reported events has been provided at this time.  Further information has been requested.; Sender's Comments: Based on reporter's causality, the event purpuric rash is assessed as possible related to mRNA-1273.
