Manipulating antigen presentation for antigen-specific immunotherapy of autoimmune diseases.

Curr Opin Immunol 2021 Apr 17;70:75-81. Epub 2021 Apr 17.

Institute of Immunology and Immunotherapy, University of Birmingham, B15 2TT, United Kingdom. Electronic address:

Current treatments for autoimmune diseases do not address the immune pathology underlying their initiation and progression and too often rely on non-specific immunosuppressive drugs for control of symptoms. Antigen-specific immunotherapy aims to induce tolerance selectively among the cells causing the disease while leaving the rest of the adaptive immune system capable of protecting against infectious diseases and cancers. Here we describe how novel approaches for antigen-specific immunotherapy are designed to manipulate antigen presentation and promote tolerance to specific self-antigens. Read More

Low dose versus standard dose four factor prothrombin complex concentrate for factor-Xa inhibitor reversal in spontaneous and traumatic intracranial hemorrhage.

Pharmacotherapy 2021 Apr 18. Epub 2021 Apr 18.

Department of Surgery, Dell Seton Medical Center, University of Texas, 1500 Red River St, Austin, 78701.

Introduction: Current neurocritical care guidelines recommend 50 IU/kg four factor prothrombin complex concentrate (4PCC) for factor Xa inhibitor (FXaI) reversal in intracranial hemorrhage (ICH) based on few clinical studies conducted among non-ICH subjects. Two recent studies suggest that low dose (25 IU/kg) 4PCC may be similar to 50 IU/kg in reversal of FXaI in ICH, and both 25 and 50 IU/kg doses are used in clinical practice for this indication. To our knowledge, no studies have directly compared 25 IU/kg versus 50 IU/kg 4PCC for FXaI reversal in ICH. Read More
