Februari 2014 Harold Ramis, star in the movie Ghostbusters and director of several movies such as Groundhog Day, died as a result of Autoimmune Inflammatory Vasculitis. (http://en.wikipedia.org/wiki/Harold_Ramis)
Autoimmune Inflammatory Vasculitis is related to Microscopic Polyangiitis and is an autoimmune vasculitis disease. (http://en.wikipedia.org/wiki/Vasculitis)
It is of course utterly necessary that research is continued to the nature, causes and therapy of autoimmune vasculitis disease.
In my case the cleansing of my blood of p-anca particles is part of the therapy to overcome the disease, next to regular dialysis and a sodium-poor diet.
As a result of my present therapy my dialysis sessions have been shortened, from 4 hours per session to 3 and a half hours per session. But 3 sessions per week still.
