Background Edoxaban, a direct FXa inhibitor, has been proven non-inferior in efficacy and safer compared to warfarin in the ENGAGE AF-TIMI 48 trial. In routine care, the safety of edoxaban has not been formally established. ETNA-AF-Europe is a multinational, multi-centre, post-authorisation, observational study (NCT02944019) conducted in 825 sites in 10 European countries. Here 13,980 edoxaban-treated patients with AF were enrolled between November 2016 and February 2018, and will be followed-up for 4 years. Methods 7,672 patients (73.4±9.26 years, 57.5% male) enrolled in the ETNA-AF Europe registry completed the one-year follow-up and were stratified into low-, intermediate- and high-risk for stroke and bleeding using the CHA2DS2-VASc and HASBLED score, respectively. We here analysed the occurrence of stroke, bleeding, intracranial haemorrhage and mortality in such categories. Results The mean CHA2DS2-VASc score at baseline was 3.1±1.38 and the mean HAS-BLED score was 2.5±1.1. Not surprisingly, patients at higher risk were older, had a lower body weight, more comorbidities, and a lower creatinine clearance. A higher proportion of patients at high risk received the reduced 30 mg edoxaban dose. Overall, the yearly event rates of stroke, intracranial haemorrhage, major bleeding and death were low. However, these rates increased consistently in patients with higher stroke and bleeding risks. Residual stroke risk on anticoagulation was comparable to the risk of major bleeding (Table 1). Outcomes by stroke and bleeding risk CHA2DS2-VASc: mean 3.1±1.38 HAS-BLED: mean 2.5±1.1 All patients Low risk (0, 1 if female) Intermediate risk (1, 2 if female) High risk (≥2, 3 if female) Low risk (0, 1) Intermediate risk (2, 3) High risk (≥4) Patients, N 233 1,133 6,304 1,224 4,932 1,516 7,672 First occurrence of outcomes, n (%/year) All-cause mortality 2 (0.92%) 12 (1.11%) 242 (4.09%) 14 (1.21%) 161 (3.47%) 82 (5.78%) 257 (3.56%) Intracranial haemorrhage 0 (0.00%) 1 (0.09%) 19 (0.32%) 2 (0.17%) 10 (0.22%) 8 (0.56%) 20 (0.28%) Major bleeding 0 (0.00%) 6 (0.56%) 62 (1.05%) 2 (0.17%) 43 (0.93%) 23 (1.63%) 68 (0.95%) Stroke/SEE 0 (0.00%) 4 (0.37%) 59 (1.00%) 3 (0.26%) 41 (0.89%) 19 (1.34%) 63 (0.88%) SEE, systemic embolic event. Conclusions In this unselected cohort of patients with AF anticoagulated with edoxaban, high CHA2DS2-VASc and HAS-BLED scores were associated with higher risks of stroke, bleeding and death. Indirectly compared with the expected rates in non-anticoagulated patients, our data underpin the value of anticoagulants such as edoxaban in patients at high risk of stroke and bleeding.

Diarrhea is one of the most common symptoms in common variable immunodeficiency, but neurologic manifestations are rare. We presented a 50-year-old woman with recurrent diarrhea and severe weight loss that developed a posterior cord syndrome. Endoscopy found a duodenal villous blunting, intraepithelial lymphocytosis, and lack of plasma cells and magnetic resonance imaging of the spine was normal. Laboratory assays confirmed common variable immunodeficiency syndrome and showed low levels of trace elements (copper and zinc). Treatment was initiated with parenteral replacement of trace elements and intravenous human immunoglobulin and the patient improved clinically. In conclusion, physicians must be aware that gastrointestinal and neurologic disorders may be related to each other and remember to request trace elements laboratory assessment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
