Help Fred Survive

My husband has been diagnosed with a rare autoimmune disease called cryoglobulinemia vasculitis.He spent three months in the hospital before the Drs diagnosed him. His kidneys failed and he was on dialysis had plasmapheresis and Rituximab He is now on Rituximab every six months and we desperately need help paying for this astronomically expensive drug If you would like to help save my wonderful caring husband we would greatly appreciate the help .
Thank you so very much.
