You are
attending a birthday party for a wonderful friend. It is time for her to cut
the cake and for everyone to indulge in the delicious cake that her mother
made. However, when you begin to take your first bite you quickly realize that
you forgot to ask if there were any peanuts used… but it’s too late. Your body
begins to defend itself against the invader and overreacts by producing
antibodies. You begin to feel extremely flushed, a tingling sensation that is unusual,
tightness in your throat, and shortness of breath. What do you do?
It is known
that those who experience a severe or life-threatening allergic reaction
(anaphylaxis) quickly inject themselves with epinephrine. Epinephrine, also
known as adrenaline, is used as the first-line treatment medication in battling
anaphylaxis before the reaction turns deadly (1). When an individual
experiences an allergic reaction and administers an injection of epinephrine
promptly, it’s shown to be extremely effective in reversing the symptoms. Epinephrine
helps release obstruction and opens the airway, strengthens the heart so that
it beats quicker and stronger, raises blood pressure and can reverse
anaphylactic shock.
However,
on CNN it was reported in August 2nd, 2013 a little girl sadly
passed away after taking a bite and spitting out a desert that did not seem
right (2). She had a severe allergic reaction to peanut butter. She was injected with epinephrine three times.
However, little is known about the length of time that had elapsed before
administering the first injection of epinephrine. If it was not administered
promptly, the effectiveness of the epinephrine injected is diminished. This
article helped me to further research the effectiveness epinephrine has on
anaphylaxis.
The
article Adrenaline auto-injectors for the
treatment of anaphylaxis with and without cardiovascular collapse in the
community written by Sheikh, Simons, Barbour and Worth assessed the
effectiveness of epinephrine injectors in helping to relieve respiratory,
cardiovascular, and other symptoms that occur during anaphylaxis by looking for
reviewed and relevant evidence (3). They looked at the effects of a variety of
epinephrine auto-injectors (EpiPen, Anapen etc.) compared to no treatment
(found to be unethical to try), a placebo (found to be unethical to try),
alternative pharmacological agent, or gaining adrenaline using an alternative
route (3). However, no new discoveries were found to support other effective
treatments other than the epinephrine injectors we currently have (3). It is
found that given the right dosage of epinephrine promptly (.01mg/kg to 0.5
mg/kg (for adults)) is necessary to help prevent anaphylaxis from worsening (4).
Once it is initially given the individual must be monitored for a certain
amount of hours to ensure that the anaphylaxis has passed and the body is
returning back to homeostasis (4).
Although
epinephrine injectors are currently the best first-line treatment of anaphylaxis,
I often wonder if there is or will be another form of medication that could potentially
become more effective in the future. The best we can do is to continue
educating others about how anaphylaxis is not a rare disease. Regardless of the
severity of an allergic reaction, prompt response with the proper medication
could mean the difference between life and death.

This is really interesting. My mom is allergic to celery and dill (weird allergies, I know) and I know she carries around an EpiPen but I've never really known the science behind it. Forgive me if I'm wrong or if this is a stupid question, but three injections of epinephrine seems like a lot for a little girl. Is it possible that the dosage could have been too much for her? It seems like too much epinephrine could take the body out of homeostasis just as easily as too little epinephrine. Is is possible either the epinephrine itself or another chemical in the injection could have had a negative effect?
