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]
Nephritis represents the ninth-most-common cause of death among all women in the US (and the fifth leading cause among non-Hispanic black women). [19] Worldwide, the highest rates [clarification needed] of nephritis are 50–55% for African or Asian descent followed by Hispanic at 43% and Caucasian at 17%. [20]
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).

Diabetic glomerulonephritis in a person with nephrotic syndrome. Secondary causes of nephrotic syndrome have the same histologic patterns as the primary causes, though they may exhibit some differences suggesting a secondary cause, such as inclusion bodies. [24] They are usually described by the underlying cause, such as: [citation needed]
As the glomerulonephritis progresses, the tubules of the kidney become infected, leading to atrophy and hyalinisation. The kidney appears to shrink. Treatment with corticosteroids is attempted if the disease progresses. [citation needed] In extremely rare cases, the disease has been known to run in families, usually passed down through the females.
Kidney disease usually causes a loss of kidney function to some degree and can result in kidney failure, the complete loss of kidney function. Kidney failure is known as the end-stage of kidney disease, where dialysis or a kidney transplant is the only treatment option.
Prerenal causes of AKI include sepsis, dehydration, excessive blood loss, cardiogenic shock, heart failure, cirrhosis, and certain medications like ACE inhibitors or NSAIDs. [5] Intrinsic renal causes of AKI include glomerulonephritis, lupus nephritis, acute tubular necrosis, certain antibiotics, and chemotherapeutic agents. [5]
A meta-analysis of four randomized controlled trials comparing treatments of membranous nephropathy showed that regimes comprising chlorambucil or cyclophosphamide, either alone or with steroids, were more effective than symptomatic treatment or treatment with steroids alone in inducing remission of the nephrotic syndrome.
