Which of the following statements accurately describes immunodeficiency disorders?

Explanation: The correct answer is c. Severe combined immunodeficiency (SCID). SCID is a group of rare genetic disorders that affect both T cells and B cells, resulting in a severe impairment of the immune system. Individuals with SCID are highly susceptible to infections and may need to live in a protected environment to avoid exposure to pathogens, hence the term "bubble boy disease."

Incorrect choices:

a. DiGeorge syndrome is a primary immunodeficiency disorder characterized by abnormalities in the development of certain organs, including the thymus, leading to impaired T cell function, but it does not affect B cell function.

b. X-linked agammaglobulinemia is a primary immunodeficiency disorder characterized by a lack of mature B cells and an inability to produce antibodies, but it does not affect T cell function.

d. Acquired immunodeficiency syndrome (AIDS) is a secondary immunodeficiency disorder caused by the human immunodeficiency virus (HIV) infection, which specifically targets and destroys CD4+ T cells, but it does not affect B cell function.

Explanation: The correct answer is c. Immunodeficiency disorders can lead to an increased susceptibility to infections. Immunodeficiency disorders are characterized by a weakened or impaired immune system, making individuals more susceptible to infections, both common and opportunistic.

Incorrect choices:

a. Immunodeficiency disorders result from a weakened immune system, not an overactive one. In overactive immune responses, autoimmune disorders may occur.

b. While some immunodeficiency disorders have a genetic basis, not all cases are caused by genetic factors. Some immunodeficiency disorders can be acquired later in life due to infections, medications, or other factors.

d. Immunodeficiency disorders are not typically treated with anti-inflammatory medications. Treatment may involve immunoglobulin replacement therapy, antiviral medications, or stem cell transplantation, depending on the specific disorder and its underlying cause.
