  • Immune System

    The immune system works to keep germs out of the body and destroy any that get in. It is made up of a complex network of cells and organs.

  • Immune Thrombocytopenic Purpura

    Immune thrombocytopenic purpura (ITP) is a blood disorder. With this disease, you have a lower amount of platelets than normal in your blood. Platelets are blood cell fragments that help with blood clotting. Having fewer platelets can cause easy bruising, bleeding gums, and internal bleeding.

  • Immunoglobulin A (IgA) Nephropathy

    IgA nephropathy is a chronic kidney disease. It progresses over 10 to 20 years, and 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. However, the IgA protein prevents this filtering process.

  • Immunoglobulin A Deficiency

    Immunoglobulin A (IgA) is a blood protein that’s part of your immune system. Your body makes IgA to help fight off sickness. Having an IgA deficiency means that you have low levels or no immunoglobulin A in your bloodstream.
