[Relentless Against SAA]

Thank you for your post. It is very interesting to find that France has less % of SAA than the USA. I wonder why.. Anyone with a theory??

The serum sickness worries me. Is your brother taking Prednisone? This is very important after ATG to prevent serum sickness. The dose is very high: usually starts at 100 mg for about 10 days, following a tapering dose over approx 2 months. I have found people on this forum who have not been given the script for Prednisone by mistake. by the way, this will also help raise his WBC count while on the steroids. The Prednisone does have its own side effects but the doctors feel those side effects are less risky than the serum sickness.
To prevent nausea, I have found the doctors tend start the patient on an acid blocker (H2 blocker) which seems to be very effective. These 2 meds are typically started immediately after the ATG if not during the ATG infusions.
Hope your brother starts feeling better soon.
