Nephritis is categorized into acute nephritis and chronic nephritis. Acute nephritis is mainly treated with rest and symptomatic treatment, and is a self-limiting disease, which can be cured by itself. Chronic nephritis, on the other hand, is a group of glomerulopathies in which the condition is prolonged, progresses slowly, and eventually develops into chronic renal failure, which generally cannot be cured on its own, and requires timely treatment to prevent or delay the progressive deterioration of renal function. The treatment of acute nephritis includes bed rest and low salt diet (less than 3g per day) during the acute stage, gradually increasing the activity level when the hematuria disappears, the edema subsides and the blood pressure recovers; at the same time, diuresis reduces the swelling, lowers the blood pressure, and prevents the occurrence of cardiovascular and cerebral complications. Chronic nephritis often requires long-term treatment, and the principles of treatment include actively controlling high blood pressure and reducing urinary protein, limiting the amount of protein in food, rationally using glucocorticosteroids and cytotoxic drugs, and avoiding factors that aggravate kidney damage. 1. Treatment of hypertension and reduction of urinary protein Commonly used drugs include angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB). 2. Limit the amount of protein in the diet. Patients with poor renal function should control protein intake and follow the high-quality low-protein method of supplementation. 3. Reasonable use of glucocorticoids and cytotoxic drugs. Generally not used, if the patient’s renal function is still good, the pathologic type is good, the urine protein is more can be tried. 4. Reduce the factors that damage the kidneys Infection, exertion, pregnancy and nephrotoxic drugs may damage the kidneys and lead to deterioration of renal function and should be avoided.
