Bo's Peanut Allergy Study Update

Today was Bo's second visit to Little Rock since we unblinded his peanut allergy treatment study and learned he was on placebo for the first year. We have been returning every 10 days instead of every 14 in order to achieve a higher daily dosage before he starts school in two weeks.

Bo's new daily dose of peanut flour treatment is now equal to about 1/12 of a peanut. He eats this every morning mixed with Motts applesauce (view a list of peanut free foods that are safe for Bo to eat). So far he has not had any type of allergic reaction to these initial low doses of peanut.

Food Allergy Safe Vacation
Since it's summer vacation time we are getting lots of questions about food allergy safe vacationing ideas. If a Disney vacation sounds like fun then your in luck, because Disney has a phenomenal food allergy safe dining program! So you and your food allergic loved ones can relax and eat safe safe while in the park! Here's a link to our past blog about our wonderful Disney peanut allergy safe vacation to FL. Many other food allergic families have posted blogs and sent e-mails with similar great reviews about Disney really supporting food allergic park visitors.

Thank You Readers
Finally, we want to acknowledge all of our readers (U.S., Australia, Canada, China, India, New Zealand, U.K., and others) who have so graciously extended their thanks and encouragement for us to stay the course with Bo's peanut allergy treatment study, especially after we learned he had been on placebo for the first year. We recognize that many of you get a strong sense of hope through Bo's peanut allergy treatment updates and we are happy to share our story, both in good times and tougher times.

P.S. As a precaution and to protect the integrity of the peanut allergy treatment study results, the study directors and researchers requested that we not post Bo's actual dosage amounts in mg but rather by using general peanut equivalent amounts. We have worked with them to understand the approx. conversions and have honored their request, including changing references to dosage mg in all previous posts.


Bo's Parents

Restarted Peanut Allergy Treatment

A fresh start for Bo
Bo has now restarted his daily peanut allergy treatment program at Arkansas Children's Hospital in Little Rock. His starting daily dosage of real peanut flour is so small it looks like 10 grains of sand in the cup.

As most of our peanut allergy study blog readers know by now, Bo is repeating year one of the peanut allergy research study. This is because on his one year anniversary of the peanut allergy treatment, he failed his oral food challenge. Then, after the one year oral food challenge, as planned, it was revealed that Bo had in fact been randomly selected to get placebo (simple flour) all year long. We knew from the beginning of this double blind study that there was a 1 in 5 chance of him being randomly selected for placebo, but hoped it wouldn't be him.

So now our journey to a cure for peanut allergy takes on a new life, as Bo is definitely receiving real peanut flour for his daily dosages now. By the summer of 2009, we should eventually get back up to the equivalent of about 9 1/2 peanut kernels!

Peanut allergy desensitization successes
While in Little Rock this week, we got to see a 5 year old boy that is in year two of a peanut allergy desensitization study at Arkansas Children's Hospital. His study is very similar to Bo's, except no one is getting placebo in that study. His daily dosage of peanut flour is now equivalent to more than 8 peanuts and we watched in amazement as his skin peanut allergy test was negative... no reaction! This lack of allergic reaction for this boy after two years of peanut desensitization treatment was remarkable considering how he has had several reactions over the course of the last two years to increases in his daily dosages of peanut flour.

In fact, we learned that some kids, after two years in these peanut allergy treatment research studies, have passed an oral food challenge equivalent to two tablespoons of peanut butter, even after going off the daily peanut flour dosage for a month!

Patience needed for treatment research
There really is a lot of promise in this peanut allergy and other food allergy desensitization research. And while everyone involved in these research programs... doctors, nurses, researchers, and the participating food allergic families are anxious to get these promising treatments out to more food allergy sufferers, there is too much risk of rolling these treatments out until the scientific community is fully satisfied that the results are long term, repeatable across larger populations, and it is clearly understood exactly how the therapy works to affect the immune system. Until these questions are answered to the satisfaction of the scientific and medical communities, premature roll out of these therapies would jeopardize all the progress being made with these type of food allergy treatment research programs.
