This 35-year-old woman reported that she had experienced three
bouts of urticaria of unknown origin about 10 years ago. The
urticaria affected her mucous membranes and skin. She had
experienced similar symptoms after repair of a fractured femur
caused by a skiing accident. These symptoms were attributed to an
antibiotic reaction.
As an emergency room nurse, she observed occasional localized
hives after the use of latex gloves. Even when she used
hypoallergenic latex gloves, she continued to have hives every few
months. Increased urticaria, at times generalized, continued to
occur.
Within 30 minutes of having a routine vaginal examination
performed by a health care provider wearing latex gloves, she had
an anaphylactic reaction that required resuscitation and
hospitalization. A vaginal biopsy 1 week later required a
latex-free environment for her safety.
A short time later, she was forced to retire from nursing
because of symptoms of asthma. She had also developed food
allergies to shellfish.
1. What are the most likely type and mechanism of the urticarial
hypersensitivity reaction?
2. What are the most likely type and cause of the anaphylactic
reaction? See instructor site for the discussion of these
questions.
