Membranoproliferative GN (MPGN), also known as mesangiocapillary glomerulonephritis, [2]: 502 is characterised by an increase in the number of cells in the glomerulus, and alterations in the glomerular basement membrane. These forms present with the nephritic syndrome, hypocomplementemia, and have a poor prognosis.
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome.The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids.
Glomerulosclerosis is the hardening of the glomeruli in the kidney. It is a general term to describe scarring of the kidneys' tiny blood vessels, the glomeruli, the functional units in the kidney that filter urea from the blood.
By contrast, membranoproliferative glomerulonephritis has a similar name, but is considered a separate condition with a distinctly different causality. Membranoproliferative glomerulonephritis involves the basement membrane and mesangium, while membranous glomerulonephritis involves the basement membrane but not the mesangium ...
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]
Mesangial proliferative glomerulonephritis (MesPGN) is a morphological pattern characterized by a numerical increase in mesangial cells and expansion of the extracellular matrix within the mesangium of the glomerulus. [1] The increase in the number of mesangial cells can be diffuse or local and immunoglobulin and/or complement deposition can ...
There are many forms of glomerulonephritis, but under a microscope, DPGN will show increased cell count of polymorphonuclear cells, cellular crescents, and fibrinoid necrosis. A patient with DPGN will have more than 50% of their glomeruli involved. [4] [5] If a patient has DPGN, that means they have an active form of glomerulonephritis. [10]
[1] [2] It may also occur as a complication of diabetes, lupus, or amyloidosis. The underlying mechanism typically involves damage to the glomeruli of the kidney. Diagnosis is typically based on urine testing and sometimes a kidney biopsy. [1] It differs from nephritic syndrome in that there are no red blood cells in the urine. [2]
