RESUMEN
As of September 2021, SARS-CoV-2 booster shots became widely available in the US to ensure continued protection against the virus. A temporal relationship has been previously reported between the first or second dose of the COVID-19 vaccine and the development of thrombocytopenia. However, adverse events related to the third COVID-19 vaccine are still being reported and studied. We report a 74-year-old male who developed bone marrow suppression and pancytopenia recorded seven days after receiving the Pfizer SARS-CoV-2 vaccine. During his hospital stay, the patient’s hemoglobin, white blood cell, and platelet levels continued to trend downwards. However, all three levels showed improvement one week after discharge without robust intervention. Global vaccination is of utmost importance, as is understanding and documenting post-vaccination reactions including bone marrow suppression. Prompt evaluation and patient education are imperative to improve patient outcomes and combat hesitancy against vaccine administration.
RESUMEN
The use of direct-acting oral anticoagulants (DOACs) has increased rapidly in the last decade; becoming the mainstay for both the prophylaxis and the treatment of venous thromboembolism in various situations including non-valvular atrial fibrillation, joint replacement surgeries and acute DVT/PE, etc. In the present times, DOACs are possibly one of the most widely prescribed medications in the developed world. The worldwide epidemic caused by COVID-19 caused significant changes in the practice of medicine worldwide. Patients who developed severe respiratory illness caused by COVID-19 were noted to develop a wide range of complications, including both arterial and venous thromboembolic complications including deep vein thrombosis and pulmonary embolism, etc. This review is an attempt to identify the role of DOACs in the treatment and prevention of these complications as well as the safety of continuing therapy with DOACs in the patients who were receiving them before contracting the infection.
RESUMEN
Thrombotic complications associated with coronavirus disease 2019 (COVID-19) have been described; these have mainly included venous thromboembolic events. Limited literature is available regarding arterial thrombosis. Acute limb ischemia is associated with severe complications that can result in significant morbidity and mortality. Herein, we report 3 cases of COVID-19 infection complicated by arterial thrombosis in the form of acute limb ischemia. Our case series adds to the limited literature regarding arterial thrombosis.
