RESUMEN
Introduction: Subacute thyroiditis (SAT) is an inflammatory disease that has different trigger factors. Recent studies show the possible role of COVID-19 vaccine-induced thyroiditis in its initiation. Herein we report the first case of post-Sputnik V vaccination SAT. Case presentation: A 42-year-old man without any specific disease was admitted due to tremors, palpation and sweating, and neck tenderness on the thyroid gland. Laboratory markers and radiologic assessments highlighted thyroiditis for him, and his symptoms were relieved by administering NSAIDs and corticosteroids. Discussion: There are several hypotheses for the etiology of post-COVID-19 immunization SAT; among them, immunologic reactions like the interactivity of human proteome with viral components and autoimmune/inflammatory syndrome induced by adjuvants (ASIA) are more probable than other discussed possibilities. We suggest further studies to discover the exact SAT pathophysiology to prevent the underlying causes among future vaccine candidates.
RESUMEN
Coronavirus disease (COVID-19) initiates several life-threatening complications including coagulopathies with a unique characteristic that made this problem challenging. Here we presented 4 cases of RT-PCR positive patients that have experienced deadly intraperitoneal hemorrhage with fourth WHO Bleeding Grade after overcoming their respiratory phase. COVID-19 could induce several coagulopathies with different features that besides iatrogenic interventions increases its mortality and morbidity due to lack of clinical evidence based on well-designed randomized clinical trials on anticoagulation therapies (AT) and administration of varieties of newly approved and non-approved medicines. This report showed the urgent need for investigation on the pathophysiology of COVID-19-associated coagulopathy esp. in hemorrhagic events which are needed to make the best therapeutic decision.
