Question 1

What is immunodeficiency?

Accepted Answer

Immunodeficiency is a state in which the immune system’s ability to fight infections, cancers, and other diseases is compromised or absent—due to either genetic defects (primary) or external factors (secondary) Source: StatPearls (NCBI Bookshelf).

Question 2

What are immunodeficiency disorders and diseases?

Accepted Answer

Immunodeficiency disorders refer to conditions where parts of the immune system are missing or dysfunctional. Primary disorders include inherited conditions like SCID or CVID, and secondary disorders include acquired immune suppression from conditions such as HIV infection or chemotherapy Source: MedlinePlus Medical Encyclopedia.

Question 3

What causes immunodeficiency?

Accepted Answer

Causes include genetic mutations (primary), infections like HIV, chemotherapy or immunosuppressive drugs, malnutrition, aging, and chronic health conditions—any of which can impair immune function Source: Wikipedia overview citing CDC.

Question 4

What are the symptoms of immunodeficiency?

Accepted Answer

Symptoms often include frequent or severe infections, slow healing, chronic fatigue, digestive issues, and in children, failure to thrive or developmental delays. Opportunistic infections or unusual pathogens may also occur Source: CDC.

Question 5

What are the types of immunodeficiency disorders?

Accepted Answer

The two main types are: Primary - Inherited from birth (e.g., SCID, X-linked agammaglobulinemia) | Secondary - Acquired later in life (e.g., from HIV, cancer treatments, or malnutrition)

Question 6

What is the difference between primary and secondary immunodeficiency?

Accepted Answer

Primary immunodeficiency is genetic and present from birth. Secondary immunodeficiency develops due to external factors like infections, medications, or other health conditions.

Question 7

Can immunodeficiency be cured?

Accepted Answer

While some forms of primary immunodeficiency can be managed or even cured with treatments like bone marrow transplant, most are chronic. Secondary immunodeficiencies may improve if the underlying cause is treated.

Question 8

When should someone suspect immunodeficiency?

Accepted Answer

Suspicion is warranted when individuals experience recurrent, severe, or unusual infections; infections in multiple sites; infections that don't respond to typical treatments; or when infections are associated with autoimmune or inflammatory complications Source: AAFP clinical guidelines.

Question 9

Which immunodeficiency diseases affect only males?

Accepted Answer

Some X-linked immunodeficiencies, such as X-linked agammaglobulinemia or Wiskott-Aldrich syndrome, typically affect only males due to how the condition is inherited.

Question 10

Who treats immunodeficiency disorders?

Accepted Answer

Immunodeficiency is usually managed by immunologists or infectious disease specialists. Depending on severity, care may also involve hematologists, pediatricians, or rheumatologists.
