Question 259 · LEK · Cross-cutting topics

An anxious mother reports symptoms that according to her and a parents' website require immunological diagnostics. She asks you to clarify which of the following could indicate primary immunodeficiency in her 1-year-old son:

1) three upper respiratory tract viral infections;
2) otitis media;
3) pneumonia;
4) recurrent oral aphthae;
5) persistent cradle cap;
6) lack of weight gain and the inhibition of normal development.
The correct answer is:
  1. A. all the above.
  2. B. 1,2,3.
  3. C. 2,3,6.
  4. D. 2,3.
  5. E. only 6.
Hint

Compare each item with the recognised warning signs of primary immunodeficiency and with the infection rate that is normal for a 1-year-old.
