Acute proliferative glomerulonephritis is a disorder of the small blood vessels of the kidney.It is a common complication of bacterial infections, typically skin infection by Streptococcus bacteria types 12, 4 and 1 but also after streptococcal pharyngitis, for which it is also known as postinfectious glomerulonephritis (PIGN) or poststreptococcal glomerulonephritis (PSGN). [4]
This disease is also caused by other diseases and toxins that damage the kidney. Both acute and chronic tubulointerstitial nephritis can be caused by a bacterial infection in the kidneys known as pyelonephritis, but the most common cause is by an adverse reaction to a medication.
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
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]
Kidney disease, or renal disease, technically referred to as nephropathy, is damage to or disease of a kidney. Nephritis is an inflammatory kidney disease and has several types according to the location of the inflammation. Inflammation can be diagnosed by blood tests. Nephrosis is non-inflammatory kidney disease.
Xanthogranulomatous pyelonephritis is an unusual form of chronic pyelonephritis characterized by granulomatous abscess formation, severe kidney destruction, and a clinical picture that may resemble renal cell carcinoma and other inflammatory kidney parenchymal diseases.
Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.

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]
