Mother had lupus and died suddenly of autoimmune hemolytic anemia that caused cardiogenic shock.is that a lupus thing or do i need 2 worry. i have ra?

Not a concern: Rheumatoid arthritis is a strikingly different entity from systemic lupus and if you are sure this is what you have, you need to work hard managing this rather than lupus. Rheumatoid arthritis can cause modest hemolysis by hypersplenism but not the catastrophic autoimmune hemolysis sometimes seen in lupus.

Lupus: Autoimmune hemolytic anemia can be part of lupus. You so not have to worry about aha if you have RA however.
