My son is 28 diagnosed w PANDAS at age 14. HD IVIG at age 16 caused severe allergic reaction on first day so no second day dose given. No preop meds given for first day. Second HD IVIG given 2010 went well and started to see slight improvement. After 4 weeks developed Severe mono which he already had a case of at age 15. has at least 40 ear, strep and sinus infections from age one. Strep pneumoniae bloodwk done in Mar 2010 showed no protection at all. In May 2011 saw immunologist who gave him pneumovax inj. A month later he had full strep protection protection. 3 months later strep protection down by 50%. Diagnosed w Specific antibody deficiency to strep pneumoniae in Oct 2011. Started on LD IVIG Nov 2011 monthly at Stanford adult infusion CTR.Helped clear up all staph boils and 40 warts, but has done nothing for PANDAS -OCD and Tourette's both severe. Yesterday met with nurse educator for infusion CTR and her passion is immune deficiencies. She said that rather than giving LD IVIG monthly giving it subcutaneous under the abdominal skin keeps the IVIG at a more even level throughout the month. It can begone at an infusion center or at home with the parent or patient learning to do the one hour weekly procedure on their own. I have yet to find a doctor who will give HD IVIG and my question is will HD IVIG help the immune def and PANDAS at the same time. Go to Immune deficiency.org and there are many tools for clinicians and patients plus a conference which will be held in Baltimore in Jun 2013. I am concerned because isome immunologists seemed interested in treating immune def, but not PANDAS. So do I need to find another doctor to treat the PANDAS. It was a very enlightening day for me.
