IgG nephropathy

IgA nephropathy, also known as Berger's disease, is a kidney disease that occurs when IgA deposits build up in the kidneys, causing inflammation that damages kidney tissues. IgA is an antibody—a protein made by the immune system to protect the body from foreign substances such as bacteria or viruses IgA nephropathy (nuh-FROP-uh-thee), also known as Berger's disease, is a kidney disease that occurs when an antibody called immunoglobulin A (IgA) builds up in your kidneys. This results in local inflammation that, over time, can hamper your kidneys' ability to filter waste from your blood. IgA nephropathy usually progresses slowly over years. IgA nephropathy is a kidney disorder that occurs when IgA (immunoglobulin A), a protein that helps the body fight infections, settles in the kidneys. IgA nephropathy can occur at any age, even in childhood. After many years, deposits of IgA may cause the kidneys to leak blood and sometimes protein in the urine

IgA Nephropathy NIDD

IgA nephropathy is a kidney disease in which IgA, a protein meant to defend the body against foreign invaders, accumulates in the kidneys and damages them. This impairs their filtering function. As a result, the kidneys begin to let substances such as blood and protein leak into the urine. 2. This condition most often occurs in Caucasian and. IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.Aggressive Berger's disease (a rarer form of the disease) can attack other major organs, such as.

IgA nephropathy (IgAN) is the most common form of glomerulonephritis worldwide, and is responsible for ~10% of glomerulonephritis in the United States.IgA nephropathy can be primary or secondary. The pathophysiology of primary IgAN is complex and incompletely understood, but key events include abnormal glycosylation of IgA molecules and subsequent autoantibody development IgA nephropathy is a chronic kidney disease. It progresses over 10 to 20 years, and it can lead to end-stage renal disease. It is caused by deposits of the protein immunoglobulin A (IgA) inside the filters (glomeruli) in the kidney. These glomeruli normally filter waste and excess water from the blood and send them to the bladder as urine

IgA nephropathy (Berger's disease) - Symptoms and causes

  1. Diagnosis. IgA nephropathy is often detected after you notice blood in your urine or when a routine test shows that you have protein or blood in your urine. These tests can help identify which kidney disease you have: Urine tests. Blood or protein in the urine, a possible first sign of IgA nephropathy, might be discovered during a routine checkup. If your doctor suspects that you have problems.
  2. IgA nephropathy is a disease that involves the accumulation of a protein (immunoglobulin A) in the kidneys. This causes inflammation. In the long term, it can severely affect kidney function. IgA nephropathy also goes by the names of Berger's disease or immunoglobulin A nephropathy.. The evolution of this disease varies greatly.

Recent international collaborative efforts have led to important discoveries that have improved our understanding of some of the key steps involved in the immunopathogenesis of IgAN. Furthermore, establishment of multicenter network
