RESUMO
Gastrointestinal (GI) bleeding is one of the most common complications associated with the use of direct oral anticoagulants (DOAC). Clear algorithms exist for the emergency measures in (suspected) GI bleeding, including assessing the medication history regarding anti-platelet drugs and anticoagulants as well as simple coagulation tests during pre-endoscopic management. Platelet transfusions, fresh frozen plasma (FFP), or prothrombin complex concentrate (4F-PCC) are commonly used for optimizing the coagulation status. For severe bleeding under the thrombin inhibitor dabigatran, idarucizumab is available, and for bleeding under the factor Xa inhibitors rivaroxaban or apixaban, andexanet alfa is available as specific antidotes for DOAC antagonization. These antidotes represent emergency drugs that are typically used only after performing guideline-compliant multimodal measures including emergency endoscopy. Antagonization of oral anticoagulants should be considered for severe gastrointestinal bleeding in the following situations: (1) refractory hemorrhagic shock, (2) endoscopically unstoppable bleeding, or (3) nonavoidable delays until emergency endoscopy for life-threatening bleeding. After successful (endoscopic) hemostasis, anticoagulation (DOACs, vitamin K antagonist, heparin) should be resumed timely (i.e. usually within a week), taking into account individual bleeding and thromboembolic risk.
RESUMO
Gene therapy has recently become a realistic treatment perspective for patients with hemophilia. Reviewing the literature and our personal experience from clinical trials, we discuss key aspects of hemophilia A and B gene therapy with vectors derived from adeno-associated virus, including predictable results, risks, adverse events, and patient-reported outcomes. Patient selection, informed consent, administration, and monitoring of gene therapy as well as data collection are explained. We also discuss the need for interdisciplinary cooperation with hepatology and other specialties. We emphasize structural and organizational requirements for treatment centers according to the hub-and-spoke model and recommend the use of electronic diaries to ensure safe and timely collection and exchange of data. Electronic diaries will play a key role as a primary source of data for pharmacovigilance, postmarketing clinical studies, national and international registries, as well as health technology and benefit assessment. Reimbursement aspects and the future of gene therapy in adolescents and children are also considered. In a rapidly evolving scientific environment, these recommendations aim to support treatment providers and payers to prepare for the implementation of gene therapy following marketing authorization.

Wiederholt hatte der Vorstand des Berufsverbandes der Deutschen Hämostaseologen (BDDH) in Übereinstimmung mit anderen Berufs- und Ärzteverbänden auf die massiven Probleme der Digitalisierung im Gesundheitswesen hingewiesen. Ärzte waren sich weitgehend einig, dass die Digitalisierung in der aktuellen Form aufgrund fehlender Akzeptanz und massiven technischen Problemen nicht umsetzbar sein wird und zum Scheitern verurteilt ist.
RESUMO
During sepsis, an initial prothrombotic shift takes place, in which coagulatory acute-phase proteins are increased, while anticoagulatory factors and platelet count decrease. Further on, the fibrinolytic system becomes impaired, which contributes to disease severity. At a later stage in sepsis, coagulation factors may become depleted, and sepsis patients may shift into a hypo-coagulable state with an increased bleeding risk. During the pro-coagulatory shift, critically ill patients have an increased thrombosis risk that ranges from developing micro-thromboses that impair organ function to life-threatening thromboembolic events. Here, thrombin plays a key role in coagulation as well as in inflammation. For thromboprophylaxis, low molecular weight heparins (LMWH) and unfractionated heparins (UFHs) are recommended. Nevertheless, there are conditions such as heparin resistance or heparin-induced thrombocytopenia (HIT), wherein heparin becomes ineffective or even puts the patient at an increased prothrombotic risk. In these cases, argatroban, a direct thrombin inhibitor (DTI), might be a potential alternative anticoagulatory strategy. Yet, caution is advised with regard to dosing of argatroban especially in sepsis. Therefore, the starting dose of argatroban is recommended to be low and should be titrated to the targeted anticoagulation level and be closely monitored in the further course of treatment. The authors of this review recommend using DTIs such as argatroban as an alternative anticoagulant in critically ill patients suffering from sepsis or COVID-19 with suspected or confirmed HIT, HIT-like conditions, impaired fibrinolysis, in patients on extracorporeal circuits and patients with heparin resistance, when closely monitored.
