Abstract Objectives This article aimed to compare nationwide time trends of oral anticoagulant prescriptions with the time trend of hospitalization for tooth extraction (TE) in Germany from 2006 through 2017. Patients and Methods We derived the annual number of hospital admissions for TE from the Nationwide Hospital Referral File of the Federal Bureau of Statistics and defined daily doses (DDD) of prescribed anticoagulants in outpatients from reports of the drug information system of the statutory health insurance. Results From 2005 to 2017, annual oral anticoagulation (OAC) treatment rates increased by 143.7%. In 2017, direct oral anticoagulants (DOACs) represented 57.1% of all OAC treatments. The number of cases hospitalized for TE increased by 28.0 only. From all the cases hospitalized for TE in Germany in 2006, 14.2% had a documented history of long-term use of OACs. This proportion increased to 19.6% in 2017. Age-standardized hospitalization rates for all TE cases with long-term use of OACs increased from 6.6 in 2006 to 10.5 cases per 100,000 person-years in 2014 and remained almost unchanged thereafter. Conclusion Our comparison showed that the large increase in OAC treatment rates in general from 2006 to 2017 had only a small impact on hospitalized TE cases with long-term use of OAC which flattens since 2014.

Direct oral anticoagulants (DOACs)—dabigatran, rivaroxaban, apixaban and edoxaban—are changing the landscape of clinical practice for patients requiring short and long-term anticoagulation. We report a patient with no history of kidney disease developing acute interstitial nephritis (AIN) after starting a DOAC, apixaban. To date, this is the first biopsy proven case of apixaban-induced AIN.

The Cost

Warfarin has been utilized for decades as an effective anticoagulant in patients with a history of strong risk factors for venous thromboembolism (VTE). Established adverse effects include bleeding, skin necrosis, teratogenicity during pregnancy, cholesterol embolization, and nephropathy. One of the lesser-known long-term side effects of warfarin is an increase in systemic arterial calcification. This is significant due to the association between vascular calcification and cardiovascular morbidity and mortality. Direct oral anticoagulants (DOACs) have gained prominence in recent years, as they require less frequent monitoring and have a superior side effect profile to warfarin, specifically in relation to major bleeding. The cost and lack of data for DOACs in some disease processes have precluded universal use. Within the last four years, retrospective cohort studies, observational studies, and randomized trials have shown, through different imaging modalities, that multiple DOACs are associated with slower progression of vascular calcification than warfarin. This review highlights the pathophysiology and mechanisms behind vascular calcification due to warfarin and compares the effect of warfarin and DOACs on systemic vasculature.

AbstractSince the earliest works on the understanding of different forms of pulmonary hypertension, thrombosis has been involved in the pathophysiology of the disease, both in pulmonary arterial hypertension (PAH) and in chronic thromboembolic pulmonary hypertension (CTEPH). Autopsy and then pathophysiological data paved the way for the use of anticoagulants as a treatment for PAH and CTEPH. In PAH their role has diminished with the advent of specific targeted therapies, but they are still prescribed in more than half of PAH patients, because of concomitant venous thromboembolism or atrial fibrillation. In CTEPH long-term anticoagulant therapy is the cornerstone of the management. The recent development of direct oral anticoagulants (DOACs) raises the question of the best anticoagulation strategy, both in patients with PAH and in patients with CTEPH. In this review, we present an overview of the history of anticoagulants in the management of patients suffering from PAH or CTEPH, an update of the available data on the underlying rationale of their use in these subjects, an alert on the potential risks of using DOACs in these poorly explored situations, and the setting up of dedicated trials to evaluate the best anticoagulant treatment strategies in patients suffering from PAH or CTEPH.

Venous thromboembolism (VTE), comprising deep vein thrombosis and pulmonary embolism, is a common condition associated with a significant clinical and economic burden. Anticoagulant therapy is the mainstay of treatment for VTE. Current guidelines recommend the use of either low molecular weight heparins or fondaparinux overlapping with and followed by a vitamin K antagonist for the initial treatment of VTE, with the vitamin K antagonist continued when long-term anticoagulation is required. These traditional anticoagulants have practical limitations that have led to the development of direct oral anticoagulants that directly target either Factor Xa or thrombin and are administered at a fixed dose without the need for routine coagulation monitoring. The paper reviews results of the trials of apixaban application for treatment and/or long-term secondary prevention of VTE. The paper analyses effectiveness and safety of apixaban in different groups of patients, as well as features of apixaban application in every day practice.

Patient Reported

Warfarin is frequently prescribed as a long-term anticoagulant in patients with end-stage kidney disease as direct oral anticoagulants undergo renal excretion. Anticoagulation is a rare cause of alopecia in adults and is thought to be due to the promotion of the ‘resting phase’ of hair follicles. In this case report, a prevalent haemodialysis female patient required long-term anticoagulation following a complex pulmonary embolus and dialysis access complications. After commencing warfarin therapy, the patient reported generalised loss and thinning of her hair. All other potential causes were excluded. Cessation of warfarin therapy and conversion to apixaban with close monitoring alleviated the hair loss. Warfarin therapy is a rare cause of alopecia but should be considered in patients on long-term anticoagulation when other diagnoses have been excluded. Hair loss has a profoundly negative impact on patient quality of life and should prompt investigation to determine the underlying cause.

Question Survey

Objectives Central-venous devices are risk-factors for upper extremity deep vein thrombosis. We surveyed physicians to identify practice-patterns and adherence to American College of Chest Physicians guidelines. Methods The 13-question survey obtained physician-demographics and treatment-choices. Respondents were grouped into surgical and medical specialists. Data were reported as ratios and percentages, and compared using Fisher’s exact test. Results We received 143 responses from physicians; 65% treated one-to-two new cases/month. Most physicians (69.2%) used anticoagulation; 36.4% retained the catheter and 32.9% removed it. Medical-specialists retained catheters more often than surgeons ( p = 0.027). For recurrences, 84% repeated anticoagulation; 50.3% retained the catheter. A majority anticoagulated upper-extremity deep-vein thrombosis in long-term catheters for three months only (55.1%). Direct oral anticoagulants were used frequently (43.6%). Only 10% believed that existing guidelines were appropriate and only 2.8% followed all guidelines. Conclusion There is great variability in treatment-decisions for upper-extremity deep-vein thrombosis. The existing guidelines are considered inadequate and not followed by most physicians.

Background The efficacy and safety of the direct oral anticoagulants (DOACs) in fragile patients (age ≥ 75 years and/or creatinine clearance levels ≤ 50 mL/min and/or body weight ≤ 50kg) with venous thromboembolism (VTE) has not been evaluated. Methods We used the RIETE database to compare the rates of the composite of VTE recurrences or major bleeding during anticoagulation in fragile patients with VTE, according to the use of DOACs or standard anticoagulant therapy. Results From January 2013 to April 2018, 24,701 patients were recruited. Of these, 10,054 (41%) were fragile. Initially, 473 fragile patients (4.7%) received DOACs and 8,577 (85%) low-molecular-weight heparin (LMWH). For long-term therapy, 1,298 patients (13%) received DOACs and 5,038 (50%) vitamin K antagonists (VKAs). Overall, 95 patients developed VTE recurrences and 262 had major bleeding. Patients initially receiving DOACs had a lower rate of the composite outcome (hazard ratio [HR]: 0.32; 95% confidence interval [CI]: 0.08–0.88) than those on LMWH. Patients receiving DOACs for long-term therapy had a nonsignificantly lower rate of the composite outcome (HR: 0.70; 95% CI: 0.46–1.03) than those on VKAs. On multivariable analysis, patients initially receiving DOACs had a nonsignificantly lower risk for the composite outcome (HR: 0.36; 95% CI: 0.11–1.15) than those on LMWH, while those receiving DOACs for long-term therapy had a significantly lower risk (HR: 0.61; 95% CI: 0.41–0.92) than those on VKAs. Conclusions Our data suggest that the use of DOACs may be more effective and safe than standard therapy in fragile patients with VTE, a subgroup of patients where the risk for bleeding is particularly high.
