RE-VERSE AD, a prospective multicentric cohort study, examined the effect of idarucizumab on 2 cohorts of patients anticoagulated with dabigatran - in cohort A in patients with uncontrollable or life threatening bleeding, in cohort B in patients who undergo acute surgery. Within the study patients were intravenously administered 5 g antidote divided into 2 doses per 2.5 g within 15 min to eliminate the anticoagulation effect of dabigatran. A series of case studies is presented to describe the use of idarucizumab within the RE-VERSE AD study and in clinical practice in the period of 2015-2016 at the University Hospital Hradec Králové. The included examples illustrate the benefit of dabigatran as the only drug so far from the group of direct oral anticoagulants which has an antidote.Key words: antidote - bleeding - dabigatran - direct oral anticoagulants - DOAC - high risk of bleeding - idarucizumab - intervention.

Anticoagulation-related nephropathy (ARN) is a significant and underdiagnosed complication in patients who receive anticoagulation therapy. It is characterized by acute kidney injury in the setting of excessive anticoagulation defined as an international normalized ratio > 3.0 in patients treated with warfarin. A definitive diagnosis is made by renal biopsy showing acute tubular necrosis with obstruction of the tubuli by red blood cell casts. However, the evidence shows that ARN can occur during treatment with novel oral anticoagulants as well. Although it has been suggested that antiplatelet therapy, such as aspirin, might contribute to coagulopathy (and therefore the hypothetical risk of ARN), there are no reports of ARN induced by antiplatelet therapy according to our knowledge. It is also reported that glomerular lesions (i.e., kidney disease) represent a risk factor for ARN. We present a case of an 82-year-old man who developed biopsy-proven ARN after the administration of dual antiplatelet therapy with no previous anticoagulation treatment and normal coagulation tests.
