To the Editor:

Long-term oral anticoagulation is recommended to prevent stroke and systemic embolism in patients with atrial fibrillation (AF) [1]. Non-vitamin K antagonist oral anticoagulants (NOACs) have emerged as the preferred choice in these patients [2].However, published data has recently demonstrated that dabigatran-PPI interaction significantly reduces dabigatran plasma levels [3, 4], most probably mediated through the effect on gastric pH [5]. This implies that dabigatran would not be highly soluble also among post-total gastrectomy patients, as they have no gastric acid secretion. Nevertheless, there are no data about post-total gastrectomy patients with non-valvular atrial fibrillation treated with dabigatran.

A 68-year-old post-total gastrectomy patient due to the diffuse large B cell lymphoma, in complete remission, and with permanent AF, was admitted to the Department of Internal Medicine I. He had been taking 150 mg of dabigatran etexilatetherapy twice daily before...
