Goodpasture syndrome (GPS), also known as anti–glomerular basement membrane disease, is a rare autoimmune disease in which antibodies attack the basement membrane in lungs and kidneys, leading to bleeding from the lungs, glomerulonephritis, [1] and kidney failure. [2]
On electron microscopy, subepithelial deposits that nestle against the glomerular basement membrane seems to be the cause of the thickening. Also, the podocytes lose their foot processes. As the disease progresses, the deposits will eventually be cleared, leaving cavities in the basement membrane.
Anti-glomerular basement membrane antibody (anti-GBM Ab) is an antibody which is found in Goodpasture's syndrome but not found in microscopic polyangiitis.. Some sources consider "anti-GBM disease" and "Goodpasture disease" to be synonymous terms describing histological presentation, reserving the term "Goodpasture syndrome" for clinical presentation.
Pulmonary-renal syndromes are most commonly caused by an underlying autoimmune disease. PRS is most commonly due to ANCA-associated vasculitides (e.g., granulomatosis with polyangiitis) or due to anti-basement membrane diseases (e.g., Goodpasture's syndrome). Granulomatosis with polyangiitis usually presents with nasopharyngeal involvement as ...
Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation. It often occurs in the glomerulus, where it is called glomerulonephritis. Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the ...
Membranoproliferative glomerulonephritis (MPGN) is a type of glomerulonephritis caused by deposits in the kidney glomerular mesangium and basement membrane thickening, [2] activating the complement system and damaging the glomeruli. MPGN accounts for approximately 4% of primary renal causes of nephrotic syndrome in children and 7% in adults. [3]
Thin basement membrane disease is an autosomal dominant inherited disease characterized by thin glomerular basement membranes on electron microscopy. It is a benign condition that causes persistent microscopic hematuria. This also may cause proteinuria which is usually mild and overall prognosis is excellent.
Video explanation. Author: Tanner Marshall Editor: Rishi Desai, MD, MPH Membranous glomerulonephritis, also known as membranous nephropathy, is where the glomerular basement membrane, or GBM, which lines the glomeruli in the kidney, becomes inflamed and damaged, which results in increased permeability and proteins being able to filter through into the urine, causing nephrotic syndrome.
