hello mr james,
welcome to helathcare magic forum ,
SLE, is a systemic autoimmune disease
that can affect any part of the body. As occurs in other autoimmune diseases, the immune system attacks the body's cells and tissue,resulting in inflammation and tissue damage.
The course of the disease is unpredictable, with periods of illness alternating with remissions,but as you have shown the follow up that shows she is responding to the treatment , as she need to continue for long period of time ,so will just suggest you to start with homoeopathic treatment along with this as it will help her body to improve her immunity level and wont suffer with any other side effects ,and as homoeopahty won't interfer the action of already given drugs , so for safe side better start of as soon as you can , as it will improve her life expectancy n quality of life .
takecare,wish you good health always !
