Official Title: Retinoids in ANCA Small Vessel Vasculitis: Silencing Autoantigens
Brief Summary: The purpose of this research study is to learn if adding all-trans retinoic acid (tretinoin) to conventional treatment of Anti- Neutrophil Cytoplasmic Autoantibodies (ANCA) vasculitis can decrease the level of disease activity.
Detailed Summary: Neutrophils are white blood cells that are the target of the ANCA antibodies. T cells are white blood cells that are involved in regulating the immune system. Laboratory research studies suggest that all-trans retinoic acid (tretinoin) can affect the neutrophils and the T lymphocytes in such a way that could decrease the abnormal immune response directed against the body own neutrophils.
