Interstitial nephritis is divided into acute interstitial nephritis and chronic interstitial nephritis, and its prognosis is as follows: 1. Acute interstitial nephritis: most patients are caused by drugs or allergies, and the prognosis is better when drugs are discontinued and allergy symptoms are actively controlled. Most patients can return to normal or to the early state of renal insufficiency, the recovery time and degree depends on the severity of the disease, the inflammatory state, the patient’s physical condition and whether the treatment is timely. Usually, acute interstitial nephritis is treated with glucocorticoids, and the prognosis is better for patients with timely application. The process of acute transformation of subacute patients into chronic, easy to become chronic disease or aggravation of the disease, Western medicine can consider combined immunosuppressive therapy; 2, chronic interstitial nephritis: because the disease is more stable, if you do not use toxic drugs and pay attention to control blood pressure, blood sugar and treatment of the original disease, patients can not enter dialysis for a long time, at least the creatinine in a stable or slowly rising stage, the patient prognosis is more The patient’s prognosis is more optimistic, but eventually uremia may appear.
