I want to thank you for treating our son. Our last fifteen years have been consumed with worry, and we have gone from one crisis to the next. Nothing has alleviated his suffering, to the point where we would have totally understood if he could not go on. Since his infusions, his life is totally different. He is reporting “great” days at work, where he couldn’t bear to be there before. His affect is completely different. His sense of humor is restored. He is socializing and enjoying it. I could go on and on. The point is, he has a life, and a happy one, and we are adjusting to a life free of dire worry. We thank you from the very bottom of our hearts for restoring our son to us and to his wife, who is in a state of amazement. The work you are doing is so important. Thank you.
