What are primary and secondary immune deficiencies and some examples of each?

Primary immunodeficiencies are the result of genetic defects, and secondary immunodeficiencies are caused by environmental factors, such as HIV/AIDS or malnutrition. This briefing explains the two different types of immunodeficiencies and how they are currently treated.

Which is a common cause of a secondary immunodeficiency disorder?

Secondary immunodeficiencies, also known as acquired immunodeficiencies, can result from various immunosuppressive agents, for example, malnutrition, aging and particular medications (e.g., chemotherapy, disease-modifying antirheumatic drugs, immunosuppressive drugs after organ transplants, glucocorticoids).
