rivaroxaban and Hematuria

Non-vitamin K antagonist oral anticoagulants (NOACs) are currently recommended for oral anticoagulation in patients with non-valvular atrial fibrillation. In the setting, NOACs effectively prevent from stroke and systemic embolic events. In spite of the favorable safety profile of NOACs when compared with vitamin K antagonists, the use of any kind of anticoagulation is associated with an increased risk of bleeding. However, there is still a lack of direct comparisons of effectiveness and safety among NOACs. The results of indirect comparisons and meta-analyses suggest that the risk of various types of hemorrhagic complications differ among the particular NOACs. Management of bleeding in patients under NOAC therapy can be challenging because of limited availability of antidotes and the lack of routine laboratory test monitoring the NOAC anticoagulant effect. In case of life-threatening or critical site bleeding, reversal of NOAC anticoagulant activity is essential together with immediate implementation of causative treatment. Moreover, some patients on chronic NOAC therapy may require urgent surgery or invasive procedures. Specific reversal agents for NOACs have been developed, i.e. more widely available idarucizumab for the factor IIa inhibitor (dabigatran) and andexanet alfa for the factor Xa inhibitors (rivaroxaban, apixaban, edoxaban) with limited availability. This review summarizes the occurrence and management of NOAC-related bleeding complications with a particular emphasis on hematuria.

To determine the probability of visible hematuria with antithrombotic agents and to evaluate association of urologic etiology in antithrombotic-related hematuria.. Preferred Reporting Items in Systematic Reviews and Meta-Analyses guidelines were followed to conduct a systematic review using search engines PUBMED and SCOPUS with the terms "(hematuria) OR (haematuria) OR urinary bleeding)) AND ((anticoagulants) OR anticoagulation) OR noac) OR novel anticoagulants) OR antiplatelet) OR dabigatran) OR rivaroxaban) OR apixaban) OR warfarin) OR aspirin) OR heparin) OR dipyridamole)." Raw data were used to perform a pooled analysis. Chi-square and logistic regression analysis were used for statistical analyses.. Twenty-two studies describing 175,114 patients met inclusion criteria. Odds ratio of hematuria with warfarin to rivoraxaban was 33 and warfarin to dabigatran was 16. The odds ratio of hematuria for oral anticoagulant (26.7%) to prophylactic parenteral anticoagulant (1.1%) agents was 9.6. Antiplatelet agents are 76 times less likely to cause hematuria compared to anticoagulants. Odds of hematuria with aspirin were 6.7 times the odds with clopidogrel and 3.5 times the odds with ticagrelor. Dabigatran was 198 times more likely to cause major hematuria compared to warfarin, whereas clopidogrel is 1.2 times more likely to cause major hematuria compared to aspirin. Urologic pathology was identified in 44% (234/532) of cases, malignancy in 24%.. Warfarin use poses the greatest risk for hematuria but is unlikely to cause major hematuria, whereas novel antithrombotic agents are more commonly associated with major hematuria. This review further characterizes the risk profile of antithrombotic agents and associated hematuria to equip clinicians with knowledge to choose an appropriate antithrombotic agent in patients with high-risk hematuria.

Clinical variables including hypertension could be linked with major bleeding events and death beyond vitamin K antagonist (warfarin) or direct oral anti-coagulants (DOACs) treatment strategy.. Subgroup analysis of major bleeding (primary endpoint) associated with clinical variables, site of bleeding, ongoing antithrombotics, reversal treatment or blood transfusion, outcomes (secondary endpoints) was performed in patients with bleeding events submitted to hard 5:1 propensity-score matching for hypertension.. Enrolled patients were 2,792 (mean age, 65.6 ± 19.9 years) during 2-year survey including 166,000 visits, of 200,000 inhabitants catchment area; 8,239 patients received warfarin and 3,797 DOACs. Hypertension account for 1,077 (39%) patients; major bleeding for 474 (17%); death for 29 (1%), and 72 (3%) on 1-month and 1-year, respectively. Hypertension, age, glucose, cancer, ischemic vascular disease, and CHA2D2VASc score were more likely to link with major bleeding. On multivariate analysis, only age (odds ratio [OR], 1.02; P < 0.001), CHA2DS2VASc score ≥ 2 (OR, 2.14; P = 0.001), and glucose (OR, 1.01; P = 0.005) were predictors of major bleeding. Kaplan-Meier analysis demonstrated patients with hypertension as compared with patients without showed 60% versus 20% death on 1-month (P < 0.001). Warfarin compared with DOACs was more likely to present with major bleeding (0.7% versus 0.2%; OR, 2.8; P = 0.005). Receiver operator characteristics analysis showed high value (0.61) of age and glucose over creatinine and systolic arterial pressure (P = NS).. Four in 10 patients with major bleeding showed hypertension; of these 8 in 10 will die within 1 month. Warfarin compared with DOACs was more likely to present with major bleeding.

Incidence, investigation and long-term follow-up of macroscopic hematuria in patients treated with non vitamin K antagonist oral anticoagulant: Insight from a specialist cardiology clinic In a retrospective long-term follow up of patients with non-valvular atrial fibrillation treated with non-vitamin K dependent oral anticoagulants in a specialist clinic, the incidence of reported macroscopic hematuria was relatively low and none of these was major bleeding. Urgent investigation of the bleeding source by a urologist showed different etiologies, like newly discovered neoplasm, benign hyperplasia of the prostate gland, renal stones, or inflammatory changes in the urinary bladder, and some had normal findings. The majority of patients continued oral anticoagulation therapy after investigation. Incidence of re-bleeding was very low.

Managing patients with new oral anticoagulants in perioperative period is not yet well protocolized. We report a clinical case of a critical haematuria after prostate biopsies to a patient treated with RIVAROXABAN. Monitoring and treatment of the haematuria have been difficult due to the lack of biological control and antidote for this treatment.
