I found a couple of articles that might be of some interest to someone. Most of you know my son was dignosied with Postural Orthostatic Tachycradia Syndrome and his symptoms keep getting more severe after infections and viruses. Currently my son is doing plasmapharisis twice a week on an out patient basis. The treatment is not causing him to be worse or increasing any of his symptoms. I am beginning to see small changes. He is gaining some strength and he is able to do some physical therapy exercises. His tremors are less. Our doctor started him on some predisone this last week. His blood pressures have also improved. Our doctor has told us this could still be a very long haul for full recovery. Research does seem to be catching up to us. My son's last testing numbers on Cam Kinese was 243. The normal range for his age is 95 or below.
