We present the case of a pregnant woman in her 20s who presented in her second trimester with severe pulmonary haemorrhage and dialysis-dependent acute kidney failure due to antiglomerular basement membrane (GBM) disease. Responding to therapy, she recovered kidney function and delivered a baby. During her pregnancy, she developed cytomegalovirus viraemia, gestational diabetes and pre-eclampsia. Here, we report the first combined use of cyclophosphamide, rituximab and intensified plasma exchange in anti-GBM disease in pregnancy, allowing minimal exposure to cytotoxic medication, resulting in live birth and dialysis independence.

Objectives: External quality assessment (EQA) programs play a pivotal role in harmonizing laboratory practices, offering users a benchmark system to evaluate their own performance and identify areas requiring improvement. The objective of this study was to go through and analyze the UK NEQAS "Immunology, Immunochemistry and Allergy" EQA reports between 2012 and 2021 to assess the overall level of harmonization in autoimmune diagnostics and identify areas requiring improvement for future actions.
Methods: The EQA programs reviewed included anti-nuclear (ANA), anti-dsDNA, anti-centromere, anti-extractable nuclear antigen (ENA), anti-phospholipids, anti-neutrophil cytoplasm (ANCA), anti-proteinase 3 (PR3), anti-myeloperoxidase (MPO), anti-glomerular basement membrane (GBM), rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA), mitochondrial (AMA), liver-kidney-microsomal (LKM), smooth muscle (ASMA), APCA, and celiac disease antibodies.

Background: Both intrinsic renal cells and immune cells contribute to driving renal inflammation and damage. However, the respective roles of intrinsic renal cells and immune cells in crescentic glomerulonephritis, and the key molecular factors driving pathogenesis are still unclear.
Methods: The roles of intrinsic renal cells and renal infiltrating immune cells in crescent formation were explored using renal transplantation after experimental anti-GBM disease induction in 129x1/svJ and C57BL/6J mice.

Rapid testing for antineutrophil cytoplasmic antibodies (ANCAs) and glomerular basement membrane (GBM) antibodies may assist in the early diagnosis of small vessel vasculitis. Clinical utility of urgent testing of these antibodies in an Australian context is not known. Our retrospective study examined the urgent test requests for ANCA and/or GBM antibodies performed over a 2-year period.

Glioblastoma (GBM) is the most common and lethal primary brain tumor. The standard treatment for newly diagnosed GBM includes surgical resection, when feasible, followed by radiotherapy and temozolomide-based chemotherapy. Upon disease progression, the anti-vascular endothelial growth factor-A (VEGF-A) monoclonal antibody bevacizumab, can be considered.

Background And Purpose: The current therapy cannot meet the needs of glioblastoma (GBM). V-domain immunoglobulin suppressor of T-cell activation (VISTA) is significantly up-regulated in GBM patients; however, its therapeutic potential in GBM is still unclear.
Experimental Approach: Flow cytometry was used to detect the expression of VISTA and the co-expression pattern of VISTA and programmed death receptor 1 (PD-1) on brain infiltrating lymphocytes of GBM mice.
