Abstract

The use of dabigatran in patients with non-valvular atrial fibrillation (AF) has widely increased in the last decades, due to its positive effects in terms of safety/efficacy. However, because of the risk of major bleeding, a great degree of attention has been suggested in elderly patients with multiple comorbidities. Notably, dabigatran mainly undergoes renal elimination and dose adjustment is recommended in patients with Chronic Kidney Disease (CKD). In this regard, the onset of an abrupt decrease of kidney function may further affect dabigatran pharmacokinetic profile, increasing the risk of acute intoxication. Idarucizumab is the approved antagonist in the case of dabigatran-associated major bleeding or concomitant need of urgent surgery, but its clinical use is limited by the lack of data in patients with Acute Kidney Injury (AKI). Thus, the early start of Extracorporeal Kidney Replacement Therapy (EKRT) could be indicated to remove the drug and to reverse the associated excess anticoagulation. Sustained Low-Efficiency Dialysis (SLED) could represent an effective therapeutic option to reduce the dabigatran plasma levels rapidly while avoiding post-treatment rebound. We present here a case series of three AKI patients with acute dabigatran intoxication, effectively and safely resolved with a single SLED session.

Summary

Peer-reviewed clinical and outcomes research relevant to anticoagulation, leech therapy, and microsurgical flap management. Indexed in PubMed and verified against the NCBI record.

Why This Matters for Hirudotherapy

This case series describes three patients with Acute Kidney Injury and acute dabigatran (a direct thrombin/factor IIa inhibitor) intoxication whose excess anticoagulation was reversed by a single session of Sustained Low-Efficiency Dialysis, after the abstract notes that the approved antidote idarucizumab lacks data in AKI. For ASH it is a reminder of the bleeding hazards and reversal challenges of modern pharmacologic anticoagulants, the backdrop against which the medicinal leech's locally acting secretome (e.g. hirudin, also a thrombin inhibitor) is studied as a drug-discovery source. Caveat: this is a small, uncontrolled case series about dialytic drug removal in a hospital setting; it concerns oral anticoagulant management, mentions neither leeches nor hirudotherapy, and should not be read as evidence for or against leech therapy.
