Recurrent infections occur when the body lacks the ability to produce antibodies which provide the defense against harmful germs. If you continue to experience severe infections over the course of a year, including new ear infections, episodes of bacterial sinusitis, have developed pneumonia more than once or have developed a severe infection that started as a common bacterial infection, you may have an immunodeficiency disorder.
People with immunodeficiency get the same kinds of infections other people get,with the difference being that their infections occur more frequently, are often more severe, and have a greater risk of complications. The most common forms of immunodeficiency are often treated with infusions of antibodies called intravenous immunoglobulins (IVIG). IVIG replaces the antibodies that your body is unable to produce. It is important to be diagnosed and treated with the correct protocol.
