MGRS disorders generally do not respond well to immunosuppressive treatment. [3] MGRS disorders also have a greater than 90% rate of recurrence if the monoclonal gammopathy is not eliminated either before or immediately after a renal transplant. [3] People with MGRS are at risk of progression to the corresponding hematologic malignancy. [3]
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.
These presenting symptoms are relatively non-specific and are often seen in other glomerular disorders. Preceding upper respiratory tract infection or post-streptococcal glomerulonephritis may contribute to hematuria, as both have been identified in patients presenting with hematuria in the context of mesangial proliferative glomerulonephritis. [2]
Cancer: as happens in myeloma, the invasion of the glomeruli by cancerous cells disturbs their normal functioning. Genetic disorders: congenital nephrotic syndrome is a rare genetic disorder in which the protein nephrin, a component of the glomerular filtration barrier, is altered.
Symptoms can be caused directly from DPGN or from a different disease that is causing DPGN. Many of the symptoms, like edema and hypertension, occur due to the decrease in glomerular filtration rate. [3] Patients can experience general systemic symptoms including fatigue, vomiting, nausea. These would all indicate uremia. [4]
Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.
This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia). [8] [10] Signs and symptoms that are consistent with nephritic syndrome include: Hematuria (red blood cells in the urine) [11]
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]
