D80-D89: Certain disorders involving the immune mechanism
D80: Immunodeficiency with predominantly antibody defects
Immunodeficiency with predominantly antibody defects refers to a group of disorders where the immune system has trouble producing enough antibodies. Antibodies are crucial proteins that help fight off infections by tagging harmful invaders for destruction. When the body doesn't make enough of these, it becomes more susceptible to infections. These disorders are typically inherited, meaning they are passed down through families. Common symptoms can include frequent infections, particularly in the ears, lungs, sinuses, and skin, which may also be severe or hard to treat. Additionally, people with these disorders may struggle with poor growth and weight gain. The progression of these conditions can vary widely, with some people experiencing mild symptoms while others may deal with serious, ongoing health problems. The immune system, specifically the parts in charge of making antibodies, is primarily affected by these conditions.
