Current statistical data shows that IgA patients can go into remission and this accounts for about 4%-20%. The survival rate within 10 years is 80%-90% and there will be 20%-30% of patients who develop progressive renal insufficiency. IgA nephropathy is a chronic kidney disease and patients will only have slight symptoms and discomforts after 10 years and the illness condition will become life-threatening after 30 years. About 35% of patients will develop end stage renal failure and the rest have persistent proteinuria and/or hematuria.
