Article Synopsis
  • - The study examined the characteristics of granulomatosis with polyangiitis (GPA) in patients who experienced induction failure, focusing on different treatments and how effective salvage therapies were from 2006 to 2021.
  • - A total of 51 patients with GPA and induction failure were analyzed, revealing that those treated with intravenous cyclophosphamide often had more severe symptoms like relapsing disease and orbital masses compared to controls, while those on rituximab showed significant renal complications.
  • - After trying salvage therapies, 69% of patients achieved remission, with a notable success in switching therapies; 50% of those inadequately responding to cyclophosphamide improved with rituximab, while patients progressing

Rationale & Objective: Hemolytic uremic syndrome (HUS), a thrombotic microangiopathy (TMA) with kidney involvement, is a rare condition in patients with monoclonal gammopathy. In the absence of known causes of TMA, the role of complement activation in endothelial injury in patients with monoclonal gammopathy remains unknown and was the focus of this investigation.

Study Design: Case series.

Objective: Rituximab is effective induction therapy in refractory or relapsing antineutrophil cytoplasmic antibody-associated vasculitis (AAV). However, further relapse is common, and maintenance strategies are required. The aim of this study was to reduce relapse rates using a fixed-interval rituximab re-treatment protocol.

Introduction: Hemophagocytic lymphohistiocytosis induced by viral diseases is a well recognized entity. Severe forms of H5N1 influenza are known to be associated with symptoms very similar to a reactive hemophagocytic syndrome. We report a case of fulminant lymphohistiocytosis associated with the pandemic A (H1N1) variant.

Objectives: To perform a literature review and develop recommendations for the use of rituximab in ANCA-associated vasculitis.

Methods: A committee of experts (five rheumatologists, five nephrologists and one paediatrician) conducted a modified Delphi exercise to identify five topics for a systematic literature search. The evidence was then reviewed, categorized according to international criteria and assimilated to form five recommendations statements and a research agenda.
