A 25-year-old woman presents with a history of recurrent
expectoration of foul-smelling sputum and intermittent
fevers. Chest x-ray discloses characteristic “tramtracking”
bronchial thickening. Physical examination
reveals coarse rhonchi in the right chest and splenomegaly.
Blood test results are normal except for low levels of
serum IgG and IgA. Her past medical history is remarkable
for frequent upper respiratory infections and for a
history of diarrhea 3 years ago due to Giardia lamblia
infection. The most appropriate therapy would be
(A) glucocorticoids
(B) glucocorticoids and an alkylating agent
(C) monthly intravenous immunoglobulin
(D) splenectomy
(E) bone marrow transplantation
A patient undergoing evaluation for possible infection
with Mycobacterium tuberculosis develops a skin
wheal 48 h after intradermal placement of TB purifiedprotein
derivative (PPD). Which of the following cellular
events accounts for these findings?
(A) Interleukin (IL)-7-induced B cell activation and secretion of
antibodies
(B) IL-3-mediated B cell activation and induction of help for
T cell activation
(C) Monocyte-derived IL-6 activation of T cells
(D) Complement-mediated endothelial cell damage
(E) CD44-mediated monocyte adhesion to endothelial cells
