How long it takes to get well from chronic nephritis treatment is very complicated and is related to the patient’s underlying disease, comorbidities, severity of the disease, intensity of treatment and sensitivity to treatment. Generally only about 1/3 of patients can be cured. Most patients may require long-term or even lifelong treatment. For example, some microscopic lesions, IgA or non-IgA tegumentary hyperplastic nephropathy, membranous nephropathy, and focal segmental glomerulosclerosis can achieve complete remission with immunosuppressive therapy. Complete remission is defined as clinically normal renal function and long-term maintenance of urinary protein below 0.3g/d. If the above criteria of complete remission cannot be achieved after various treatments, then long-term maintenance therapy is required. The main purpose of taking medication at this time is to delay the deterioration of kidney function and enter the uremic phase as late as possible in order to improve the quality of survival of patients. Patients who normally take medications regularly may have their kidney function enter the uremic phase 5 or even 10 years later than patients without treatment. The more commonly used medications are mainly Bering capsules, Jin Shui Bao capsules, Huang Qiao capsules, Dipyridamole, Valdecoxib, and sometimes hormones such as prednisone are also used. Besides taking medication for treatment, it is also important to avoid factors that worsen kidney function, such as hypertension, hyperuricemia, infection, hypercalcemia, diarrhea and vomiting. These factors can aggravate the kidney function and repeatedly hit the kidneys, which will enter the uremic phase early, so they must be controlled and avoided in general.
