The repression of the vascular endothelial growth factor (VEGF) can also cause glomerular TMA (damage to the glomerular microvasculature). It is likely that the absence of VEGF results in the collapse of fenestrations in the glomerular endothelium, thus causing microvascular injury and blockages associated with TMA. [8]
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.
The relationship of IgM and mesangial proliferative glomerulonephritis is hypothesized to involve either formed or deposited IgM complexes in the mesangium leading to T-cell mediated inflammatory response, mesangial proliferation, and glomerular injury or, as a result of mesangial proliferation, decreased clearance of monocytic IgM complexes.
Nephrotic syndrome has many causes and may either be the result of a glomerular disease that can be either limited to the kidney, called primary nephrotic syndrome (primary glomerulonephrosis), or a condition that affects the kidney and other parts of the body, called secondary nephrotic syndrome.
Similar to other causes of nephrotic syndrome (e.g., focal segmental glomerulosclerosis or minimal change disease), membranous nephropathy is known to predispose affected individuals to develop blood clots such as pulmonary emboli. Membranous nephropathy in particular is known to increase this risk more than other causes of nephrotic syndrome ...
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]
The damage to the basement membrane causes bleeding, and the disease often presents in patients as hematuria and haemoptysis (coughing up blood). If not treated promptly with plasmapharesis to remove the autoantibodies, it can lead to permanent damage in the lungs/kidneys.
The cause of diffuse proliferative glomerulonephritis (DPGN) depends on the severity of the disease. DPGN is a secondary disease, in that a disease that a patient already has causes DPGN to occur. The most common associated disease of DPGN is severe systemic lupus erythematosus(SLE). [4] Specifically, Lupus nephritis class IV. [5]
