Abstract
The safety of direct oral anticoagulants (DOACs) in patients after solid organ transplantation (SOT) is not well defined. This study aimed at describing the safety and efficacy of DOACs in patients after SOT. Patients after kidney and/or liver transplantation under maintenance immunosuppression treated with rivaroxaban (n = 26), apixaban (n = 20) and edoxaban (n = 1) were included. Clinical data were collected retrospectively and using a questionnaire. DOAC plasma levels and thrombin generation (TG) were measured in patients after SOT and compared with nontransplanted controls receiving DOACs. DOACs were administered for 84.6 patient-years. Mean immunosuppressive trough levels after DOAC initiation increased from baseline by 18.8 ± 29.6% compared to 3.0 ± 16.5% in matched controls (P = 0.004), without significant differences in dose adjustments. No transplant rejection or significant change in liver or renal function was observed. There was one major bleeding after the observation period but no thromboembolic complication. DOAC plasma levels reached the expected range in all patients. The intrinsic hemostatic activity in transplanted patients was higher compared to nontransplant controls. Treatment with DOACs after SOT is safe and effective. Immunosuppressive trough levels should be monitored after DOAC initiation, particularly in the early phase after SOT. These data should be confirmed in a prospective study.

Abstract
The solid organ transplant community is slow to adopt the routine practice of using direct oral anticoagulants. Rivaroxaban and apixaban share common metabolic pathways with tacrolimus. This study aimed to clarify the impact of rivaroxaban/apixaban on tacrolimus troughs. Fifty solid organ transplant recipients with concomitant use of tacrolimus and rivaroxaban/apixaban were retrospectively assessed for changes in tacrolimus troughs and dose. Average dose-adjusted tacrolimus troughs and average tacrolimus total daily doses prior to and after rivaroxaban/apixaban initiation were compared. Subgroup analyses evaluating rivaroxaban and apixaban individually were performed. Rivaroxaban was prescribed to 18 recipients, and apixaban was prescribed to 32 recipients. Transplanted organs included kidney (n = 22), lung (n = 18), liver (n = 7), simultaneous pancreas and kidney (n = 1), and simultaneous kidney and liver (n = 2). The median doseadjusted tacrolimus trough and tacrolimus total daily dose prior to rivaroxaban/apixaban initiation was 2.15 ng/mL/mg (IQR 1.17, 3.37) and 4 mg (IQR 1.88, 6.25), respectively. The median dose-adjusted tacrolimus trough and tacrolimus total daily dose after rivaroxaban/apixaban initiation was 2.16 ng/mL/mg (IQR 1.24, 4.10) and 3.55 mg (IQR 1.5, 6.35), respectively. No significant difference was found between average dose-adjusted tacrolimus troughs or tacrolimus total daily doses before and after rivaroxaban/apixaban initiation or in the individual subgroup analyses for rivaroxaban/apixaban. It is unlikely that initiating rivaroxaban/apixaban affects tacrolimus troughs or requires tacrolimus dose adjustment. This study does not elucidate if tacrolimus affects rivaroxaban/apixaban pharmacokinetics or pharmacodynamics.

Abstract
Limited information is available about use of direct oral anticoagulants (DOACs) in lung transplant recipients (LTRs). The purpose of this study is to describe the indications and use of long-term anticoagulation, including the safety and tolerability of DOACs, in LTRs. This was a single-center retrospective study. LTRs who received therapeutic anticoagulation were identified. Patient characteristics, indications for treatment, and complications of therapy were obtained. A total of 203 patients underwent lung transplantation of which 118 patients (58.1%) had an indication for anticoagulation. Patients with an indication for anticoagulation were older than those without (59 ± 14 years versus 48 ± 17 years, p < 0.001) and were more likely to be male (72.0% versus 50.6%, p = 0.002). Of the patients with indication for anticoagulation, 74 (62.7%) received it. Fifty-one (68.9%) of patients receiving anticoagulation were treated with DOACs. In the patients receiving anticoagulation, there were 14 major bleeding events in 13 patients, of which 3 were receiving DOACs and the remainder were receiving heparin or warfarin. The need for anticoagulation is common in LTRs for both atrial arrhythmias and venous thromboembolism. However, many patients with atrial arrhythmias do not receive anticoagulation. The use of DOACs is well tolerated and safe in LTRs.
