Therapeutic measures were taken as a result of hypophysitis, diabetes insipidus. When she received the second SARS-COV-2vaccine (BNT162B2: Pfizer-biontech) on June 27, 2021, she still reported persistent polydipsia, polyuria, headache, and lethargy. The day after her second vaccination, the patient reported exacerbation of polyuria and polydipsia, with urinary frequency every hour. The daily urinary output was approximately 4 L She also noted worsened headache, excessive fatigue, and multi joint pain. She reported a significant weight loss of a total of 18 kg since the first vaccination. She finally presented to the emergency department of our medical center on August 27, 2021 for increasing fatigue, intolerable polydipsia, polyuria, headache with nausea emesis, and light-headedness. She denied syncopal episodes, vision changes, and altered mental status. Upon history taking. She admitted no menses since the first vaccination. Prior to that. Her menses had been regular. Her family history was unremarkable for autoimmune disease. Conclusion: report a rare case of possible SARS-COV-2 vaccine-related hypophysitis, Which led to diabetes insipidus. Endocrinopathy after SARS-COV-2 vaccination is, indeed, possible Endocrinopathy is associated with infrequent complications; however, it may be underestimated in the post-sars-cov-2-vaccinated population. Further studies are warranted to better understand endocrinopathy and its possible association with SARS-COV-2 vaccination. Sender's Comments: Based on the current available limited information in the case provided, the causal association between the events Hypophysitis and Diabetes insipidus and the use of suspect product BNT162b2 cannot be fully excluded. The case will be reassessed once further information is available The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events.
