IgA nephropathy is an immunopathological diagnostic term for chronic glomerulonephritis, indicating that the patient has chronic nephritis. In fact, chronic nephritis does not have a concept of complete cure. Stage two patients indicate that the inflammatory reaction within the glomerulus is not very severe, but the patient may also show more proteinuria. In most cases, the renal function of these patients is still normal, and it may be necessary to decide whether to choose medications such as corticosteroids based on the amount of proteinuria. If the patient responds well to medication, the proteinuria may significantly decrease, or even turn negative, but it cannot be completely cured, as this is a chronic disease, and there is also a possibility of relapse in the later stages of the disease. (Please follow the doctor's orders regarding medication use.)
