Direct oral anticoagulant and AKI: apixaban-induced acute interstitial nephritis.

Direct oral anticoagulants (DOACs)-dabigatran, rivaroxaban, apixaban and edoxaban-are changing the landscape of clinical practice for patients requiring short and long-term anticoagulation. We report a patient with no history of kidney disease developing acute interstitial nephritis (AIN) after starting a DOAC, apixaban. To date, this is the first biopsy proven case of apixaban-induced AIN.
