What can cause secondary immunodeficiency?
Other causes of secondary immunodeficiency include: severe malnutrition, certain chronic diseases such as diabetes, immunosuppressive medication or chemotherapy, certain cancers such as leukemia, and the absence of the spleen (sometimes the spleen must be removed because of trauma, for example).
What are secondary immunodeficiency diseases?
A secondary immune deficiency disease occurs when the immune system is compromised due to an environmental factor. In contrast, primary immunodeficiency diseases (PIDD) are a group of disorders caused by inherited or genetic defects in the cells and tissues of the immune system.
Which condition places patients at risk for secondary immune deficiency?
Secondary immunodeficiency (SID) occurs when the immune system is weakened by another treatment or illness. What causes secondary immunodeficiency? There are many potential causes of SID but the most common examples are blood or bone marrow disorders, drugs (medicines) and treatment for cancer.
What is the difference between primary and secondary immunodeficiency disorders?
Immunodeficiency disorders result in a full or partial impairment of the immune system. Primary immunodeficiencies are the result of genetic defects, and secondary immunodeficiencies are caused by environmental factors, such as HIV/AIDS or malnutrition.
