Pancytopenia; suspected macrophage activation syndrome; Multisystem inflammatory syndrome (MIS); Sjögren's syndrome; Sore arm; This literature-non-study case was reported in a literature article and describes the occurrence of MULTISYSTEM INFLAMMATORY SYNDROME (Multisystem inflammatory syndrome (MIS)), PANCYTOPENIA (Pancytopenia) and SJOGREN'S SYNDROME (Sjögren's syndrome) in an 18-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. LITERATURE REFERENCE: Concurrent medical conditions included Asthma exercise induced. On 16-Mar-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form.

In June 2022, the patient experienced SJOGREN'S SYNDROME (Sjögren's syndrome) (seriousness criterion medically significant). The patient was hospitalized from 25-Mar-2021 to 31-Mar-2021 due to MULTISYSTEM INFLAMMATORY SYNDROME and PANCYTOPENIA. At the time of the report, MULTISYSTEM INFLAMMATORY SYNDROME (Multisystem inflammatory syndrome (MIS)), PANCYTOPENIA (Pancytopenia) and SJOGREN'S SYNDROME (Sjögren's syndrome) had not resolved.

The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown) was unknown. For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments. This case refers to Patient 11 from Table 1 who received Moderna COVID-19 vaccine. Concomitant medications were not reported. Patient had no history of COVID-19. Five days later (after vaccination), developed fevers, headaches, sore arm, and shortness of breath. On 23-Mar-2021, patient presented to the emergency room (ER) with shortness of breath, cough, myalgia, fatigue, and persistent fevers up. Vital signs were measured and lab investigations were performed. A CT scan of the chest was done and the patient was discharged. But the patient continued to feel ill. On 24-Mar-2021, physician suspected an adverse reaction to the COVID-19 vaccine. The next day, patient returned to the ER complaining of cough, sore throat, and chest heaviness. Vitals on presentation were measured, and patient was unable to speak in full sentences. Laboratory tests were performed and the patient was hospitalized. The following morning, patient was started on cefepime and doxycycline. On 27-Mar-2021, due to worsening oxygenation, patient was placed on high-flow nasal cannula (HFNC) oxygen. Hematology started methylprednisolone 50 mg intravenously every eight hours. The next day, oxygenation started to improve. On 29-Mar-2021, she was transitioned to prednisone 20 mg orally once daily. The next day, she was off supplemental oxygen. Laboratory tests improved. A pediatric rheumatology consultation found no clinical features suggestive of Sjögren's syndrome but suspected this illness represented macrophage activation syndrome. Over the subsequent months and follow-up visits with hematology and rheumatology, patient continued to have multiple somatic complaints. Nine months post-hospitalization, she continued to complain of brain fog, fatigue, and dizziness'. Patient's blood work was normal. Patient moved away for college, but symptoms continued to evolve. Patient complained of dry eyes and mouth and bilateral hand pain with morning stiffness. In June 2022, she was diagnosed with Sjögren's syndrome. The patient was placed on hydroxychloroquine. More than two years after her original illness onset, she continued to feel unwell with ongoing dry eyes, joint pain, and intestinal issues, including diarrhea, constipation, and bloating. This is a descriptive case series prospectively identified and collected by the authors during formal or informal consultation from January to December 2021. The aims of this descriptive case series were twofold. First, to present detailed clinical case presentations of serious adverse event following immunization (AEFI) with COVID-19 vaccines seen at one rural healthcare system during the first year after the introduction of COVID-19 vaccines. Second, to review the medical literature regarding similarly reported cases. Author concluded that they encountered a variety of AEFI with COVID-19 vaccines, including myocarditis, demyelinating disease, encephalitis, Bell's palsy, burning mouth syndrome, MIS, ITP, pneumonitis, colitis, staphylococcal infection, and erythromelalgia. This detailed case series were presented to help clinicians consider a diagnosis of AEFI when no other explanation had been found after a thorough diagnostic evaluation. These described adverse events following COVID-19 vaccination do not imply causality. They hope this descriptive case series leads to further case-control studies from healthcare organizations to explore the possible risks, incidence, and causal relationships of such adverse events following COVID-19 vaccination.
