Garcia2 1Division of Hematology/Oncology, Department of Medicine, University of California, San Francisco, San Francisco, CA; and 2Division of Hematology, Department of Medicine, University of Washington, Seattle, WA A 70-year-old male with a history of atrial fibrillation who is being anticoagulated with dabigatran etexilate presents to the emergency room with melena. He reports taking his most recent dose of dabigatran more than 2 hours ago. On examination, he is hypotensive and tachycardic, and he continues to have melanotic stools. Laboratory testing reveals a calculated creatinine clearance of 15 mL/min, a prothrombin time of 16. You are asked by the emergency medicine physician whether hemodialysis should be considered to decrease the patient’s plasma dabigatran level. Published reports have shown Learning Objective that 4 hours of hemodialysis can reduce the plasma concentration of ● To describe recommendations for or against the use of dabigatran by 59%-68%,13,14 although drug levels can increase after hemodialysis for dabigatran-associated major bleeding and intermittent dialysis sessions due to redistribution from extravascu- the underlying evidence, based on a review lar compartments. Keywords “dabigatran” (1979 hits), “hemodialysis” (56 risk reduction of stroke and embolism associated with atrial hits), and “hemorrhage” or “bleeding” yielded 41 articles.

After absorption and conversion to its include original data, 1 was a survey, 1 did not involve active form, dabigatran reversibly binds to thrombin’s active site, hemodialysis, and 2 did not involve bleeding. Nine studies were preventing its conversion of fibrinogen to fibrin. Dabigatran’s plasma included: 1 retrospective database review, 2 retrospective case concentration peaks within 1. Dabigatran is primarily excreted through the kidneys (85%), with the remainder excreted in the bile. All except 1 patient took dabigatran bleeding associated with dabigatran 150 mg twice daily versus 3 for AF.

Best et al showed 2 variants at chromosome 6q21 to be cussed. Finally, current recommendations on optimal follow-up of associated with subsequent malignant neoplasm in survivors of HL long-term survivors are summarized. Ma et al showed that genetic variation in FGFR2 influences breast cancer Late effects after HL 8 risk in HL patients treated with radiotherapy. A diverse array of late effects of HL therapy have been documented. Several studies focusing on competing mortality after HL therapy have shown that, whereas deaths from HL level off after the first Leukemia 10-15 years, deaths from other causes, most notably second Earlier studies showed an increased leukemia risk with the use of malignancy and cardiac disease, continue to increase over time. MOPP (mechlorethamine, vincristine, procarbazine, and predni- Figure 1 shows the cumulative incidence of cause-specific mortality sone) chemotherapy, and the use of large-field radiotherapy further of 1542 stage I and II HL patients treated from 1967 to 2007 at the contributes to the risk.

Several studies have demon- strated a direct correlation between breast cancer risk and radiation field size14-17 and also showed that smaller fields and treatment volume are associated with a significantly lower risk of breast cancer. In a population-based study comparing outcome of de novo breast cancer versus breast cancer after HL, women with localized breast cancer after HL had a significantly increased 2-fold risk of death from breast cancer compared with patients with de novo breast cancer. The latter supports the importance of early breast cancer detection in women with history of chest irradiation for HL. Cumulative incidence of cause-specific mortality of Lung cancer long-term HL survivors. Both radiotherapy and alkylating chemotherapy contribute to the risk of lung cancer after HL.

Several case-control studies showed that of a wide range of cardiovascular complications, including coronary estimated prior radiation doses to the specific area where the breast artery disease, valvular disease, pericardial disease, arrhythmia, and cancer developed, compared with doses to a similar area in the cardiomyopathy. The increased risk typically emerges after a controls, showed a clear radiation dose-response relationship on latency of 10 years and remains persistently elevated over time. In the largest study that included 120 addition, it is a key contributor to the excess mortality seen in cases of breast cancer after HL and 266 controls, the relative risk of long-term HL survivors. The risk of cardiac disease is directly breast cancer increased significantly with increasing radiation dose, related to radiation doses.

Due to the risks of relapse buy discount cozaar 50 mg on-line diabetic retinopathy definition, TTP patients require follow-up toms that are similar to TTP and can also be associated with partial, with ADAMTS 13 monitoring and elective therapy can be rather than severe, deficiency in ADAMTS13. Recently, a mutation in factor H has been associated with thrombotic microangiopathy Other/emerging treatments for TTP associated with ADAMTS13 deficiency. However, further work is clearly required to be associated with further risks/complications (allergic/anaphylactic determine the link between complement activation and perturbation reactions, thrombosis, infection). Therefore, new safer and simpler of the VWF-ADAMTS13 axis. At this time, therapeutic recombinant ADAMTS13 is not available, but hopefully its availabil- Treatment of TTP ity is just a matter of time. In inherited TTP patients, the provision of TTP is an acute, life-threatening illness that is a medical emergency a recombinant ADAMTS13 concentrate will very likely simplify requiring prompt treatment.

ADAMTS13 appears to be fully corrective of complete genetic VWF-cleaving function. In acquired TTP, the success of plasma exchange is linked to both the provision of ADAMTS13 and the removal of inhibitory Anti-VWF therapy antibodies. Therefore, to remove the need for plasma exchange, Strategies that target VWF have been explored recently for the recombinant ADAMTS13 would need to be provided at levels that alleviation of TTP symptoms. Because the clinical features of TTP exceed patient antibody titers to restore ADAMTS13 activity to are primarily linked to elevated plasma UL-VWF and hyperreactive nonpathological levels. VWF A1 domain may specifically prevent formation of platelet-rich microvascular thrombi seen in TTP. To date, 3 strategies have been An alternative for acquired TTP patients may be the provision of an explored to accomplish this: an aptamer (termed ARC1779),47 a ADAMTS13 variant. Recent studies have shown that the spacer humanized mAb (termed GBR600),48 and a bivalent nanobody domain is a major antigenic target for autoantibodies. Indeed, there (termed ALX-0681),49 all of which bind the VWF A1 domain and appears to be some overlap between a functional exosite on specifically block VWF binding to platelet GpIb. Using the same ADAMTS13 and a core antigenic region recognized by inhibitory baboon model of acquired TTP, both GBR600 and ALX-0681 antibodies in TTP patients.

Targeting VWF may therefore represent an effective Willebrand factor from human endothelial cells.
