Abstract:
A 48-year-old woman presented with a fever, microscopic hematuria, proteinuria, and rapid deterioration of the renal function. Pulmonary alveolar hemorrhaging and a high level of anti-glomerular basement membrane (GBM) antibodies (700 IU/mL) were observed. Based on her medical history and positive findings of serum lupus anticoagulant, anti-phospholipid antibody syndrome (APS) was suspected. A renal biopsy revealed cellular crescentic glomerulonephritis with thrombosis, suggesting anti-GBM disease with catastrophic APS. The patient was treated with pulse steroid therapy, plasma exchange, hemodialysis, and intravenous cyclophosphamide pulse therapy. To our knowledge, this is the first report of a patient with anti-GBM disease and APS.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
