Abstract
The characteristics of direct oral anticoagulants (DOACs) make them more appealing for prevention of thromboembolic events than vitamin K antagonists (VKA). Despite that, both classes have been a recognized as a cause of anticoagulant related nephropathy (ARN). Herein we describe a case of a 72-year-old man, with chronic kidney disease (CKD), medicated with rivaroxaban, who presented with acute kidney injury (AKI) and microscopic hematuria. The kidney biopsy revealed anticoagulant related-nephropathy. Rivaroxaban was suspended, the patient showed improvement of renal function and apixaban was prescribed. This case emphasizes the need for careful monitoring of serum creatinine when these drugs are prescribed, especially in high risk groups.
Implication for health policy/practice/research/medical education:
This report highlights the importance of awareness of anticoagulant related nephropathy, especially in patients with risk factors and that it should be suspected whenever eGFR is impaired in a patient taking DOAC.
