B Cell Deficiencies Flashcards
Deficiency tyrosine kinase that block B cell maturation
Bruton X linked agammaglobulinemia (Ig replacement)
Low Ig, no circulating B cells
Bruton X linked agammaglobulinemia (Ig replacement)
Deficiency of CD40 L on activated T cell
X linked hyper IgM syndrome (Ig replacement)
High serum titers of IgM, susceptible to extracellular bacteria
X linked hyper IgM syndrome (Ig replacement)
Most common B cell deficiency
Selective IgA deficiency
Repeated sinopulmonary and GI infxn
Selective IgA deficiency
Ig decrease over time
Common variable immunodeficiency (antibiotics)
Delayed onset of maturation of normal IgG
Transient agammaglobulinia (antibiotics)
Spontaneous resolution, diagnosed in infants
Transient agammaglobulinemia (antibiotics)
DiGeorge syndrome
Congenital thymic aplasia
Only disease that is T cell specific; facial abnormalities, hypoparathryoidism, cardiac malformation
DiGeorge syndrome
CATCH22 syndrome
Cardiac abnormalities, abnormal facies, thymic hypoplasia, cleft palate, hypocalcemia
Defect in cystoskeletal glycoprotein
