Goodpasture Syndrome is described as a single episode disease entity. It is diagnosed with the demonstration of antiglomerular basement (anti-GBM) antibodies in plasma or renal tissue. Although the recurrence of anti-GBM disease is rare, it has been reported in up to 3% of cases. Recurrence with negative anti-GBM antibodies in plasma is even less frequent We report a 63 years old male in whom anti-GBM disease recurred without detectable anti-GBM antibodies in plasma, despite having positive antibodies at the onset.

Glioblastoma-associated macrophages & microglia (GAMs) are critical immune cells within the glioblastoma (GBM) microenvironment. Their phagocytosis of GBM cells is crucial for initiating both innate and adaptive immune responses. GBM cells evade this immune attack by upregulating the anti-phagocytic molecule CD47 on their surface.

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.

Introduction: Glomerular basement membrane (GBM) disease is a severe and exceedingly rare disorder characterized by the presence of circulating antibodies targeting the non-collagen NC1 domain of the α3 chain of collagen type IV in glomerular and alveolar basement membranes. It typically presents as rapidly progressive glomerulonephritis (RPGN), often accompanied by pulmonary hemorrhage. The occurrence of double-seropositivity for anti-GBM antibody and anti-neutrophil cytoplasmic antibody (ANCA), primarily with myeloperoxidase specificity (MPO-ANCA), is particularly uncommon in pediatric cases.

Article Synopsis
- Managing immune-mediated kidney diseases in elderly patients (≥75 years) is challenging due to age-related health issues and comorbidities.
- Current classification systems and treatment guidelines are insufficient for this age group, necessitating a more tailored approach.
- Treatment often involves immunosuppressive therapies, but careful drug choice and dosage are essential to minimize side effects, requiring a collaborative and patient-centered management strategy.

Article Synopsis
- Acute kidney injury during pregnancy is fairly common, but anti-GBM disease is a rare cause, as illustrated by a 30-year-old woman who experienced impaired kidney function during her pregnancy.
- A kidney biopsy revealed she had crescentic glomerulonephritis due to anti-GBM antibodies, which prompted aggressive treatment including steroids and plasma exchange, leading to improvement in her kidney function.
- Despite the successful treatment, the patient developed malaria later in pregnancy, resulting in complications that required an emergency cesarean section, but she ultimately delivered a healthy baby at 33 weeks.
