Clinical narrative: Autoimmune hemolytic anemia; Off label use; This study case was reported in a literature article and describes the occurrence of AUTOIMMUNE HAEMOLYTIC ANAEMIA (Autoimmune hemolytic anemia) in a 41-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.    Concurrent medical conditions included Central retinal vein occlusion and Hypertension. Concomitant products included ASPIRIN [ACETYLSALICYLIC ACID] for Central retinal vein occlusion, METOPROLOL SUCCINATE for Hypertension.    In March 2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date,  after starting mRNA-1273 (Moderna COVID-19 Vaccine), the patient experienced AUTOIMMUNE HAEMOLYTIC ANAEMIA (Autoimmune hemolytic anemia) (seriousness criteria hospitalization prolonged, medically significant and life threatening) and OFF LABEL USE (Off label use). The patient was hospitalized on sometime in March 2021 due to AUTOIMMUNE HAEMOLYTIC ANAEMIA. The patient was treated with RITUXIMAB for Autoimmune hemolytic anemia, at a dose of 1000 milligram; RITUXIMAB for Autoimmune hemolytic anemia, at a dose of 1000 mg; PREDNISONE (oral) for Autoimmune hemolytic anemia, at a dose of 1 mg/kg once a day; IMMUNOGLOBULINS NOS (IMMUNE GLOBULIN) (intravenous) for Autoimmune hemolytic anemia, at a dose of 1 gram per kilogram and MYCOPHENOLATE MOFETIL (oral) for Autoimmune hemolytic anemia, at a dose of 1000 milligram twice a day. At the time of the report, AUTOIMMUNE HAEMOLYTIC ANAEMIA (Autoimmune hemolytic anemia) outcome was unknown and OFF LABEL USE (Off label use) had resolved.

For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered AUTOIMMUNE HAEMOLYTIC ANAEMIA (Autoimmune hemolytic anemia) and OFF LABEL USE (Off label use) to be possibly related.    Patient received her first dose of the SARS-CoV-2 mRNA-1273 vaccine in Mar-2021. Seven days after vaccination, she noted fatigue and dark urine. Twenty days after vaccination, she was admitted to another hospital. The patient continued to feel unwell, and two days following discharge from the other hospital (35 days after vaccination), she presented to another hospital with persistent fatigue and dyspnea on exertion. The patient worked as an attorney and lived with her husband and three children. She had no personal or family history of autoimmune disease. On admission to hospital, the patient was in mild distress. She was discharged home on hospital day 14 (49 days after receiving the vaccine). She was given two additional weekly doses of rituximab (1,000 mg) as an outpatient, and corticosteroids and MMF were tapered.Author informed that there was a strong clinical suspicion that the SARS-CoV-2 mRNA vaccine was the inciting event for the AIHA based on the chronology of events, the atypical autoantibody profile, and the absence of other causes. Patient's initial DAT was negative when tested with Gammaclone (Immucor) anti-IgG reagent, which does not recognize IgG4 or some types of IgG3, but positive when a reagent that detects all IgG isotypes (gel system, Ortho) was used during the elution studies. These unusual findings suggest that the warm (IgG) autoantibody consisted of an atypical subtype of either IgG4 or IgG3. Workup also revealed the presence of a cold autoantibody with a thermal amplitude of 37°C, indicating that our patient may have developed a mixed warm/cold AIHA, which comprise approximately 8% of cases of AIHA. Author concluded that patient developed a robust AIHA one week after receiving her first dose of the SARS-CoV-2 mRNA vaccine. Although causation cannot be proven, the temporal relationship in the absence of an alternative cause argues in favor of de-novo vaccine-induced AIHA.    Most recent FOLLOW-UP information incorporated above includes: On 29-Sep-2021: Follow up received by safety on 30-Sep-2021 included an Email received from team and does not contain any new information.; Sender's Comments: This case concerns a 41-year-old female patient with  no relevant medical history, who experienced the serious  unexpected event Autoimmune hemolytic anemia. The event occurred approximately 7 days after the first dose of mRNA-1273 Moderna vaccine. The rechallenge was not applicable, as a second dose of the vaccine was deferred. The benefit-risk relationship of mRNA-1273 Moderna vaccine is not affected by this report.
