What does RPGN stand for?
Rapidly progressive glomerulonephritis (RPGN) is a disease of the kidney characterized clinically by a rapid decrease in the glomerular filtration rate (GFR) of at least 50% over a short period, from a few days to 3 months.
Can RPGN be treated?
As a result, various conditions that present with RPGN may be treated with a similar type of regimen, using combinations of immunosuppressive agents, and adjunctive therapies; however, specific dosing protocols may vary.
Is RPGN an autoimmune disease?
Antiglomerular basement membrane antibody disease Anti-glomerular basement membrane (GBM) antibody disease is an autoimmune glomerulonephritis and accounts for up to 10% of RPGN cases.
What are the signs and symptoms of rapidly progressive glomerulonephritis?
Signs and symptoms Most types of RPGN are characterized by severe and rapid loss of kidney function with marked hematuria; red blood cell casts in the urine; and proteinuria sometimes exceeding three grams in twenty-four hours, a range associated with nephrotic syndrome.
Is lupus nephritis a RPGN?
Lupus nephritis is associated with significant increase in mortality in patient with SLE [6]. Untreated RPGN particularly, carries a poor prognosis and unavoidable progress to the final stage of renal disease.
What does Pauci-immune mean?
Pauci-immune (pauci- Latin: few, little) vasculitis is a form of vasculitis that is associated with minimal evidence of hypersensitivity upon immunofluorescent staining for IgG. Often, this is discovered in the setting of the kidney.
How is rapidly progressive glomerulonephritis treated?
The recommended initial treatment is with glucocorticoids with either cyclophosphamide or rituximab with or without plasmapheresis. Plasmapheresis is indicated if there is a rapid deterioration of renal function or severe renal involvement at the time of presentation.
What is RPGN in kidney disease?
(Crescentic Glomerulonephritis) Rapidly progressive glomerulonephritis (RPGN) is acute nephritic syndrome accompanied by microscopic glomerular crescent formation with progression to renal failure within weeks to months. Diagnosis is based on history, urinalysis, serologic tests, and renal biopsy.
Which biopsy findings are characteristic of glomerular regurgitation nephropathy (RPGN)?
Early renal biopsy is essential. The feature common to all types of RPGN is focal proliferation of glomerular epithelial cells, sometimes interspersed with numerous neutrophils, that forms a crescentic cellular mass (crescents) and that fills Bowman space in > 50% of glomeruli. The glomerular tuft usually appears hypocellular and collapses.
What is an endometrial biopsy?
Endometrial Biopsy. An endometrial biopsy is a medical procedure in which a small piece of tissue from the lining of the uterus (the endometrium) is removed for examination under a microscope. The removed tissue is examined for cancer or any other cell abnormalities.
What kind of instrument is used for a uterine biopsy?
A type of forceps may be used to hold the cervix steady for the biopsy. You may feel some cramping when it is applied. Your provider may insert a thin, rod-like instrument, called a uterine sound, through the cervical opening to find the length of the uterus and location for biopsy.
