Answer 8

SCID

Question 9

Delayed separation of umbilicus and recurrent bacterial infections…

Answer 9

Leukocyte adhesion deficiency

Question 10

Failure to produce IFN-gamma, and inability for neutrophils to response to chemotactic stimuli.

Answer 10

wiskott Aldrich syndrome

Question 11

Inability to class switch, leading to increased pyogenic infections early in life. Labs show increased IgM

Answer 11

Hyper IgM Syndrome

Question 12

increased bleeding diathesis, eczema, recurrent otitis media

Answer 12

Wiskott Aldrich Syndrome

-Increased IgE, IgA, decreased IgM
-x linked recessive

Question 13

Lack of Isotype switching that leads to deficiency in some type of immunoglobulins most commonly A

Answer 13

Selective Ig deficiency

Question 14

Lack of NADPH oxidase

Answer 14

Chronic Granulomatous disease

Question 15

Microtubule defect leading to recurrent pyogenic infections, partial albinism and peripheral neuropathy

Answer 15

Chediak Higashi syndrome

Question 16

increased pyogenic upper and lower resp infections

Labs show normal number of B cells but decreased plasma cells and immunoglobulin

what is this pt at risk of developing?

Answer 16

pt has Common variable Immunodeficiency

@ risk of devleoping autoimmune diseases and lymphoma
