Review[Anti B-cell-antibody treatment for maintenance of remission in granulomatosis with polyangiitis and microscopic polyangiitis].
Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are the most frequent primary necrotizing small vessel vasculitides. In these formerly fatal diseases remission can be induced by stage- and activity-adapted immunosuppressive regimens in the majority of patients. This does not lead to drug-free long-term remission or even cure. ⋯ Recent randomized controlled trials demonstrated that maintenance treatment with the anti-B-cell antibody Rituximab, administered 6-monthly as opposed to azathioprine leads to a significantly lower relapse rate but a similar profile of adverse events. These data enabled the extension of the approval of Rituximab for maintenance of remission treatment of GPA and MPA in Germany in 2018. Guidelines and expert recommendations concerning measures of infection prevention and vaccination of immunosuppressed patients as well as the management of hypogammaglobulinemia and cytopenia on Rituximab are presented in this review.

Education of medical students requires teaching students how to navigate in the broad field of medical research. The objective of this article is to provide an overview about medical research and to show how to denote a medical study in a concise fashion. Medical research can be classified into categories according to the object of investigation. ⋯ Each research category uses a specific set of study types with names such as cross-sectional study, case-control study etc. The article describes the principles of the study types. Together, research category and study type briefly describe the design of a medical study.
