I. Overview Acute glomerulonephritis is often referred to as acute nephritis. Broadly speaking, it refers to a group of glomerulonephritis with different etiology and pathogenesis, but every day clinically manifested as a combination of acute onset, characterized by hematuria, proteinuria, edema, hypertension and decreased glomerular filtration rate, so it is also often called acute nephritis problem syndrome. The vast majority of clinical cases in Sichuan are acute post-streptococcal glomerulonephritis. This syndrome is the most common kind of kidney disease in pediatric period. Age is more common in children. Second, the symptoms: 1-3 weeks before the onset of the disease there is a history of antecedent infection (episodes of infection, purulent tonsillitis, scarlet fever, purulent skin infections, bronchitis, pneumonia, etc.). Clinical UK manifestations of typical acute nephritis: hematuria, often carnal hematuria, can also be microscopic hematuria, hematuria begins to praise a period of time can be authoritative at the same time varying degrees of proteinuria; swelling, the face, eyelids, lower limbs and other places are common, swelling is tense; oliguria; such as measuring blood pressure, can be found in the majority of scientific patients in the bachelor’s blood pressure has different degrees of elevated doctor. Severe cases: some children may develop acute renal failure, heart failure, hypertensive encephalopathy, and impaired consciousness within 1-2 weeks of onset. There are also some atypical cases. The main treatment is based on the presence of streptococcal prodromal infection, decreased serum C3 and renal puncture biopsy to clarify the beginning diagnosis. The acute phase should be bed-ridden for two weeks. When the edema subsides, the blood pressure drops to normal, and the hematuria disappears, the patient can get out of bed for light activities; the disease is not suitable for genetic sports activities or heavy physical labor within three months; 2. When strict surgical control of protein intake (eggs, chicken, duck, fish, meat, animal offal such as liver, kidney, etc.), do not listen to unfounded prescriptions and rumors, such as dirty to make up for dirty, eat more nutrition, so that nitrogenous substances into too much, increasing the burden on the kidneys, resulting in adverse consequences; in the increase in urine volume, azotemia should be restored as soon as possible after the elimination of protein supply. 3, antibiotics for arthritis application: in order to completely remove the residual bacteria from the body, penicillin can be given at the beginning of the disease center for 7-10 days. 4, symptomatic good at treatment: diuretic, lowering blood pressure. 5.Seriously ill patients need alternative treatment such as hemodialysis or hemofiltration. Prognosis: 1, more than 90% of acute nephritis can be fully recovered, leaving no sequelae. 2, severe cases are the main established cause of death, so the BoD must be found in a timely manner in multiple cases and learn to treat correctly. 3, health through a large number of cases of long-term follow-up by doctors proved that at least 5-10% of patients magazine disease within a year urine can not be completely normal, lasting more than 1 year or longer, some of which can still recover. 4, about 3-5% of the patients to be able to continue not to heal, the formation of medical chronic process, affecting kidney function.
