Hello @johnbishop and thanks for the info. Very hard to find any information on this rare autoimmune disease. About a year ago, I received 4 treatments four weeks in a row and did not see any improvements. In September 2022, they decided to go with a different approach and prescribed it for every 3 months for at least 1 year and then reevaluate my health after 4 treatments. Next treatment the end of December.
