Hi, I was diagnosed with APBA, which is what your child has, also know as aspergillus, when I was 12. Do you have any idea what his level was? The levels are supposed to be in the 200's, and at one point, my level, an Ige it's called, was 1700. For me, aspergillus meant ALOT of steriods. Steriods are the primary treatment for this, but there is also an anti-fungal medicine called sporanox. Make sure your doctor discusses both options with you, because steriods are not something you want your child on for an extended period of time. I was steriods for 6 mos at a time once. They make you moody, gain a lot of water weight, and have trouble sleeping. All toll, I would say it took 4 years to get my aspergillus totally under control. I'm 21 now, and I haven't had any problems with it in the last 3 yrs. I hope this didn't seem really gloom and doom, but I just thought I would share my story with you. Best of Luck Mary
