Coagulopathy and Extremely Elevated PT/INR after Dabigatran Etexilate Use in a Patient with End-Stage Renal Disease.

Introduction. Dabigatran is an oral direct thrombin inhibitor which has been approved for prophylaxis of stroke in patients with atrial fibrillation. The use of dabigatran etexilate increased rapidly due to many benefits.

Autoimmune hepatitis: diagnostic dilemma in the setting of suspected iron overload.

Autoimmune hepatitis (AIH) is an inflammatory condition of the liver that has a multitude of clinical presentations from chronic hepatitis to acute fulminant hepatitis. AIH diagnosis is typically suspected after ruling out other causes of hepatitis (such as vial hepatitis, hemochromatosis, Wilson's disease, and primary biliary cirrhosis) through serological tests and by findings of high titers of certain autoantibodies (ANA and anti-SMA for type 1 AIH and anti-LKM-1 for type 2 AIH). AIH like most inflammatory conditions is associated with increased ferritin levels (acute-phase reactant) but typically near-normal transferrin saturation.

Expanding the repertoire of Modified Vaccinia Ankara-based vaccine vectors via genetic complementation strategies.

Background: Modified Vaccinia virus Ankara (MVA) is a safe, highly attenuated orthopoxvirus that is being developed as a recombinant vaccine vector for immunization against a number of infectious diseases and cancers. However, the expression by MVA vectors of large numbers of poxvirus antigens, which display immunodominance over vectored antigens-of-interest for the priming of T cell responses, and the induction of vector-neutralizing antibodies, which curtail the efficacy of subsequent booster immunizations, remain as significant impediments to the overall utility of such vaccines. Thus, genetic approaches that enable the derivation of MVA vectors that are antigenically less complex may allow for rational improvement of MVA-based vaccines.
