Acute femoral artery occlusion in a male with Duhring disease and COVID-19 pneumonia treated with baricitinib.

Arterial thromboembolic events (ATE) in COVID-19, similarly as venous thromboembolism (VTE), are observed mainly in severely ill patients. ATE include brain, heart, aortic, and peripheral ischemic complications which usually aggravate a course of the disease leading to lifethreatening conditions.
A Case Report: The authors describe a case of a 53-year-old male with Duhring disease in the remission period admitted due to severe COVID-19 pneumonia. The patient was treated with ceftriaxone (2000 mg once daily), dexamethasone (8 mg once daily), enoxaparin (60 mg twice daily), baricitinib (4 mg once daily), and remdesivir (200 mg on the first day, followed by 100 mg within 4 consecutive days); he required high flow oxygen therapy. On day 5 of hospitalization, he began to suffer from pain of the right lower extremity; in physical examination the limb was cold with absent femoral, popliteal, and pedal pulses. Urgent computed tomography angiography revealed total occlusion of the right superficial femoral artery (SFA) in the absence of any atherosclerotic plaques in the aorta. The patient was intubated and transferred to department of vascular surgery, where a giant clot was removed from SFA. Unfortunately, the patient outcome was unfavorable due to respiratory failure progression. The authors underline that ATE may occur even in anticoagulated patients and that association of some therapeutic options of COVID-19, like janus kinase (JAK) inhibitors use with an increased risk of ATE, should not be excluded.
