A 2-year-old girl has had repeated ear and upper respiratory tract infections since she was born. A pediatrician has determined a diagnosis of transient hypogammaglobulinemia of infancy. What is the physiological origin of the child’s recurrent infections?

- The child was born with immunoglobulin A (IgA) and immunoglobulin (IgM) antibodies, suggesting intrauterine infection.
- The child lacks the antigen presenting cells integral to normal B-cell antibody production.
Which of the following phenomena would be least likely to result in activation of the complement system?
- Recognition of an antibody bound to the surface of a microbe
- The binding of mannose residues on microbial glycoproteins
- Activation of Toll-like receptors (TLRs) on complement proteins
- Direct recognition of microbial proteins

- “A particular cytokine can have varied effects on different systems, a fact that limits their therapeutic use.”
- “Cytokine production is constant over time, but effects are noted when serum levels cross a particular threshold.”
- “Most cytokines are produced by granular leukocytes, and different cells are capable of producing the same cytokine.”
- “Cytokine actions are self-limiting in that activation of one precludes activation of other cytokines with similar actions.”

- Decreased platelet count
- Normal vitamin K levels
- Normal leukocyte levels
A child has been diagnosed with thalassemia. Which of the following other health problems is the child at risk for?
