Decreased Bleeding Incidence with Direct Oral Anticoagulants Compared to Vitamin K Antagonist and Low-Molecular-Weight Heparin in Patients with Sickle Cell Disease and Venous Thromboembolism.
    Acta haematologica, 2019, Volume: 142, Issue:4

    Venous thromboembolism (VTE) is a recognized complication of sickle cell disease (SCD), yet the optimal pharmacologic anticoagulant is unknown.. A retrospective single-institution cohort study of patients with SCD complicated by first VTE from January 2009 through July 2017 was performed using ICD 9/10 codes. Data collected included the anticoagulant used, VTE recurrence, and incidence of bleeding.. 109 patients with VTE were identified. SCD genotypes included HbSS in 92 (84%), HbSC in 13 (12%), and HbS-β+ thalassemia in 4 (4%). After the initial VTE event, 32 patients received a vitamin K antagonist (VKA), 34 for low-molecular-weight heparin (LMWH), and 43 for direct oral anticoagulants (DOACs). 16 patients (15%) experienced a clinically significant bleeding event, including 9 on VKA, 5 on LMWH, and 2 on DOACs. At a median follow-up of 11.8 (range, 3.4-60) months, 33 patients had a recurrent VTE, including 10 on VKA, 10 on LMWH, and 13 on DOACs (p = 0.833). Bleeding incidence was least with the DOACs, which were associated with fewer bleeding events (OR 0.22), and greatest with VKA (OR 1.55) (p < 0.05).. There was no difference between VTE recurrence and choice of anticoagulation in SCD patients with VTE. Bleeding events were lower for DOACs compared to VKA or LMWH.

Sickle cell intrahepatic cholestasis with cholelithiasis.
    Pediatric hematology and oncology, 2006, Volume: 23, Issue:2

    Sickle cell intrahepatic cholestasis (SCIC) is a rare complication seen in sickle cell patients who present with sudden onset of RUQ pain, progressive hepatomegaly, mild elevation of transaminases, coagulopathy, and extreme hyperbilirubinemia. Early recognition of this entity is essential to avoid life-threatening complications. Diagnosis can be challenging given the overlap in clinical presentation with other conditions affecting the hepatobiliary biliary system in sickle cell anemia such as hepatitis, cholecystitis, and hepatic crisis. Treatment is currently limited to exchange transfusion. The authors present two patients with SCIC and cholelithiasis; the clinical picture of one is complicated by choledocholithiasis.
