AbstractCharacteristic features of disseminated intravascular coagulation (DIC) are the opposing risks of bleeding (due to consumptive coagulopathy and hyperfibrinolysis) and organ failure (due to widespread microvascular thromboses). The purpose of anticoagulation in DIC is to attenuate excessive thrombin generation and fibrin deposition. While heparins have been shown to be beneficial in this context, the safety and efficacy of direct oral anticoagulants have not yet been sufficiently addressed. Here, we report two patients in whom chronic DIC was stabilized upon administration of apixaban: an elderly male with aortic dissection presenting with significant mucocutaneous bleeding and a younger female with Klippel–Trénaunay–Weber syndrome presenting with multiple superficial vein thromboses (SVTs). In addition to an improvement in DIC parameters, both patients benefited clinically with resolution of bleeding symptoms and prevention of further SVTs, respectively. Oral apixaban thus showed promising safety and efficacy in the management of DIC caused by vascular abnormalities; still further investigations are needed to support these findings.

Aim. Clinical characteristics of disseminated intravascular coagulation (DIC) in COVID-19 infection and assessment of the effectiveness of complex therapy for this syndrome at the stages of prevention and treatment of various complications. Materials and methods. The study of publications was carried out through search engines on the Internet using keywords. To diagnose the infection, the COVID-19 program was used on the MeDiCase platform, which is publicly available on www.medicase.pro, which suggests a diagnosis with a sensitivity of 89.47%. The study included 85 patients with acute COVID-19 with mild to moderate disease, aged 11 to 81 years. The presence of the pathogen was confirmed immunologically in 12% of patients; in other cases, the diagnosis was based on the results of an automated survey in the MeDiCase system. All patients, according to the MGNOT recommendations, were prescribed one of the oral direct anticoagulants - Eliquis at a dose of 5 mg 2 times a day, Ksarelto at a dose of 10 mg 2 times a day or Pradax at a dose of 110 mg 2 times a day for at least 2 weeks. All other drugs with antiviral, immunomodulatory effects, antibiotics were canceled. Results. The presence of DIC is substantiated by the morphological picture of changes in organs and tissues, clinical (hematoma-petechial type of bleeding in combination with thromboembolic syndrome and the presence of thrombovasculitis) and laboratory changes: an increase in the level of soluble fibrin-monomer complexes, D-dimer, hyperfibrinogenaemia, less often - thrombocytopenia, violation of fibrinolytic activity. The phenomenon of consumption of clotting factors and profuse bleeding are rare. Direct anticoagulants, fresh frozen plasma transfusions and plasmapheresis are used in the treatment of disseminated intravascular coagulation. The paper presents its own positive results of early prescription at the outpatient stage of direct oral anticoagulants in prophylactic doses (no case of disease progression), individual cases of the use of fresh frozen plasma and plasapheresis. Conclusion. DIC syndrome with the development of thrombovasculitis is the most important pathogenetic mechanism for the development of microthrombotic and hemorrhagic disorders in organs during infection with COVID-19, leading to dysfunction of the lungs, brain and other nerve tissues, kidneys, thromboembolic complications, etc. Many symptoms of the disease may be associated with a violation of the nervous regulation of the functions of organs and systems. Prevention of thrombovasculitis is effective already at the stage of the first manifestation of the disease with the outpatient use of direct anticoagulants (oral, low molecular weight heparins). In case of more severe manifestations (complications) of the disease, additional use of freshly frozen plasma and plasmapheresis is effective.

AbstractDisseminated intravascular coagulation (DIC) is a relatively rare but life-threatening condition, the outcome of which depends largely on timely and accurate therapeutic management. Inhibiting the activation of blood coagulation is an effective option for limiting the burden of diffuse intravascular thrombosis for attenuating consumption of clotting factors and platelets and ultimately preventing massive bleeding. Direct oral anticoagulants (DOACs) are a relatively new generation of drugs that specifically inhibit activated factors II (thrombin) and X, thus providing effective anticoagulation while concomitantly limiting the hemorrhagic risk compared with other conventional anticoagulant agents. The peculiar mechanism of action would hence at least theoretically support their usage in patients with DIC, especially in those with a more pronounced thrombotic phenotype. A comprehensive literature search on the use of DOACs in patients with intravascular coagulopathies currently yielded only 15 documents, all case reports, totaling 21 patients (dabigatran, n = 5; rivaroxaban, n = 13; apixaban, n = 3; edoxaban, n = 0). Taken together, the current literature data suggest that these drugs may have low prophylaxis efficacy and thereby their indication for preventing DIC in high-risk patients may be limited. Nevertheless, DOACs seem at least therapeutically equivalent to heparin in some forms of DIC, especially in those with prevalent thrombotic phenotype, while having more favorable oral administration. The inherent risk of hemorrhages from heparin injection is also shared by DOACs; therefore, their use in DIC patients with a prevalent bleeding phenotype will probably remain unwarranted. Major caution should also be used in patients with impaired drug metabolism, especially those progressing toward liver or renal failure or receiving aggressive antimicrobial treatment. Where potentially indicated, further clinical trials should be planned to test the therapeutic efficacy of these drugs in patients with different types or forms of DIC.

Background: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults and children. Initial treatment with heparin followed by wafarin is the mainstay of treatment. Only insufficient experience is available for direct oral anticoagulants (DOACs). Aims: The study aims to demonstrate the efficacy and safety of DOACs such as (Rivaroxaban and Dabigatran) in patients with objectively confirmed CVT. Methods: Data of 46 cases of CVT collected using a standardized case report form. Inclusion criteria were patients diagnosed with CVT, confirmed by CT or MRI imaging. Results: The total number of patients was 46 (9 males and 37 females). The mean age of the patients was 35.2± 5 years. The most common clinical manifestations among our patients were headache followed by seizure. 52% of cases were unprovoked, while 48% were provoked by pregnancy and oral contraceptive pills. Superior sagittal sinus (55%) and transverse sinus (44.9%) were the most common sites. Involvement of more than three venous sinuses was 34.8%. Thrombophilic abnormality was detected in 21.7% of patients. Initiation of anticoagulation (AC) was mostly low molecular weight heparin (LMWH) (80%), followed by unfractionated heparin (UFH) (17.7%) and fondaparinex (2%). Maintenance AC with Rivaroxaban after heparin (LMWH/UFH) was in 63% of our patients, the rest were switched from Warfarin to Rivaroxaban (34.8%), and one was treated by Dabigatran (2%). CVT recurrence was observed in one patient. Major bleeding (according to ISTH criteria) was not reported in our case series. Conclusions: DOACs demonstrated good safety and efficacy profile and can potentially replace warfarin in CVT patients. Disclosures No relevant conflicts of interest to declare.

Background: The availability of direct oral anticoagulants (DOAC) in clinical practice has transformed the health care provided to patients for the prevention and treatment of thromboembolism. Safety and efficacy data guide clinicians in the choice of the drug used. To date, no evidence is available from head-to-head trials comparing different DOAC with regard to safety and efficacy; information is mainly derived from several meta-analyses and real-life studies. Conclusions from these studies are inconsistent and unsatisfactory. The evaluation of self-reported adverse drug reactions (ADR) available from databases of drug-regulatory agencies such as the Italian Medicines Agency (AIFA) pharmacovigilance database represents a novel aid to guide decision-making. Objective: To analyze potential suspected ADR of DOAC using a previously described risk index (RI) in daily clinical practice in Italy. Methods: The National Pharmacovigilance Network database (from the AIFA website) was searched in order to retrieve information on all ADR related to oral anticoagulants occurring from 2013 to 2018. The ADR RI for each drug was calculated, where an RI = 1 indicates a balance between the percentage of ADR share and the percentage of market share for each DOAC; and an RI <1 indicates a rate of ADR lower than the rate of market share (safer DOAC). The following DOAC molecules were considered: dabigatran, rivaroxaban, apixaban, and edoxaban. Results: The results showed that rivaroxaban is the DOAC with the lowest RI among the 4 molecules available today in Italy. Conclusions: Based on the RI, we identified rivaroxaban as the DOAC having the best safety profile.

A disseminated intravascular coagulation (DIC) was induced in rats by injection of 1 mg endotoxin and subsequent infusion of isotonic saline (500 ml/kg/5 hours) over a period of 5 hours. Animals were treated beginning at the time of initial glomerular fibrin deposition with heparin (1000 IU/kg) or aprotinin (40000 KIU/kg) or heparin-aprotinin in combination (each drug as given as in single dose). The first half-dasc was given as an bolus injection 2 hours after the endotoxin injection, the second dose immediately was added to the saline infusion. The extent of DIC was controlled by several blocdparameters, histological examination of the kidneys, and by the application of 125–I-fibrinogen (given after starting DIC) and 131-I-fibrinogen (injected after beginning the therapy). By the use of two isotopes it was possible to observe the behaviour of the fibrinogen in two different phases.Heparin had clearly favorable effects stabilizing the situation of hemostasis, although the fibrinogen turnover was not normalised completely, probably due to fibrin monomers which even polymerize in presence of heparin. The beneficious effect of heparin was diminished by the addition of aprotinin which given alone had deleterious effects inhibiting the spontaneous removal of fibrin thrombi. The fibrinogen turnover was clearly enhanced supporting the concept that the plasma fibrinogen level cannot be protected by blocking the fibrinolysis which is very rarely generalized.
