The specific treatment of nephritis depends on the specific disease, each person appears with different symptoms, different causes, different pathologies, and different treatment methods, which need to be judged comprehensively according to the symptoms and test results to choose the right treatment. Common nephritis treatment methods are as follows: a. Primary: nephritis is mild, there is heavy, there is acute, there is slow, and there are various types of pathology. In acute nephritis, the main thing is to pay attention to rest, give anti-infection and symptomatic management of complications. If it is acute glomerulonephritis, patients need kidney puncture, most of them need to give glucocorticoids plus cytotoxic drugs, and some severe patients even need hemodialysis and plasma exchange. If it is chronic nephritis and the condition is very mild, with only hematuria, no drugs can be used and observation and monitoring is sufficient. If the urine protein is below 1g/d, there is no hypertension or renal impairment, and there is no contraindication, ACEI or ARB type drugs can be applied. If the urine protein is greater than 1g/d or shows nephrotic syndrome, kidney puncture is needed to decide the treatment according to the pathology, and most of them will apply immunosuppressive therapy. If the nephritis is already in CKD stage 3 or later, it is recommended to treat according to chronic kidney disease, avoid factors that aggravate kidney damage and treat all complications. Second, secondary: common secondary nephritis are lupus nephritis, purpura nephritis, nephritis caused by hepatitis B virus infection and so on. The treatment of the disease, the first need to treat the primary disease, that is, the need to treat systemic lupus erythematosus, allergic purpura and hepatitis B and other diseases. In addition, the development of the treatment plan needs to be combined with the kidney involvement to decide the treatment plan. Some patients need to perfect the kidney puncture biopsy and choose the best drugs according to the pathological type. Third, hereditary: such as Alport syndrome, such diseases are genetic diseases, due to genetic problems, there is no special treatment, can be maintained through drugs to maintain physiological functions.
