how long one should be on maintenance doses beyond remission

[elephant]

You need a second opinion. Having blood and protein on and off is a concern and needs to be watched carefully. How is his blood pressure?

My son, age 13 at diagnosis was only on predisone for a year. He was on cytoxan for 4 months than changed to methotrexate. HIs doctor says that the goal is at 2 years to be drug free. On a side note, the only time his ANCA was negative was when he was on cytoxan. He has had blood in his urine for over a year now and protein off and on. kidney doctor still finds it a mystery.

I agree with what elephant just said.

Have you seen a urologist?
