IgA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA).Antibodies are large proteins produced by the body to fight infections caused by invaders, such as bacteria, viruses, fungi, parasites, and other foreign agents.gA is found in the saliva, mucous membranes, and intestinal secretions, where it may serve as the first line of defense against various sinus, respiratory, and gastrointestinal infections. Consequently, a deficiency of IgA heightens oneâs vulnerability to such infections.
IgA nephropathy (IgAN), also known as IgA nephritis, Berger disease (/ b ÉÉr Ë Ê eÉª /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy); specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney. IgA nephropathy is the most common glomerulonephritis worldwide. Primary IgA nephropathy is characterized by deposition of the IgA antibody in the glomerulus. There are other diseases associated with glomerular IgA deposits, the most common being IgA vasculitis (formerly known as HenochâSchÃ¶nlein purpura [HSP]), which is considered by many to be a systemic form of IgA nephropathy.
