IgA nephropathy is the most common glomerulonephritis worldwide; the global incidence is 2.5/100,000 per year amongst adults. [1] Aggressive Berger's disease is on the NORD list of rare diseases. [2] Primary IgA nephropathy is characterized by deposition of the IgA antibody in the glomerulus.
The symptoms at onset are very similar to IgA nephropathy and include abdominal pain, hematuria, edema, and oliguria. [ 18 ] Henoch–Schönlein purpura (HSP) - Often considered a systemic form of IgA nephropathy , Henoch–Schönlein purpura (HSP) is a systemic small-vessel vasculitis that is characterized by deposition of IgA antibody immune ...
IgA nephropathy is the most common cause of MesPGN. [3] It is thought abnormally glycosylated IgA form polymers and deposit in the mesangium. [3] Subsequently, IgA immune complexes bind to IgA receptors on mesangial cells and induce injury to mesangial cells through release of cytokines and growth factors that promote infiltration of leukocytes ...
Glomerulopathy includes collapsing glomerulopathy, glomerulocystic kidney disease, glomerulomegaly, membranous nephropathy, and tip lesion glomerulopathy. [2] Collapsing glomerulopathy (CG) is a clinicopathologic entity that involves hypertrophy and hyperplasia of podocytes and segmentar or global collapse of the glomerulus. [3]
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]
In cases of IgA nephropathy, focal proliferative glomerulonephritis is observed in about 20–50% of renal biopsy specimens. Twenty to sixty percent of patients with lupus who underwent renal biopsies exhibit focal proliferative or mesangial lupus nephritis.
IgA nephropathy. This is a condition in which small amount of a type of normal antibody (called IgA) get stuck in the kidney as it passes through in the bloodstream. This is a chronic condition, which sometimes goes away on its own but occasionally can cause damage to the kidneys. A related condition called IgM nephropathy can sometimes cause pain.
In IgA nephropathy, episodes of frank hematuria are more common, and a family history is less common. A kidney biopsy is the only way to diagnose thin basement membrane disease. It reveals thinning of the glomerular basement membrane from the normal 300 to 400 nanometers (nm) to 150 to 250 nm.
