Nephritic syndrome is a group of symptom and sign that caused by many kinds of kidney diseases, and its complications have: infection, thromboembolic complications, acute renal failure and so on.
1、Acute renal failure syndrome includes prerenal azotemia、acute tubular necrosis and idiopathic acute renal failure. Prerenal azotemia can be improved with diureses; renal tubular necrosis is mostly seen middle age and elderly with small artery changed and elastic layer expansion, more than 85% is glomerular minor lesion; the reason of idiopathic acute renal failure is unknown, maybe relate with edema of renal interstitium oppress the renal tubule or the renal tubule is blocked by protein cast, made the internal pressure of renal tubule increased, the filtration of renal tubule decreased. Most patients cure the disease except dialysis. A few patients need dialysis treatment. In addition, rapidly progressive glomerulonephritis and renal vein thrombosis also cause acute renal failure, need to recognize.
2、thrombus、embolism complications fibrinogen and blood coagulation factor increased, increase the number of platelet, hormone and diuretic aggravation made the blood in hypercoagulability condition, be easy to happen thrombus、embolism complications, the rate up to 8%-50%, seen mostly deep vein thrombosis.
3、infection, the patients are infected by immune globulin and the standard of complement factor B decreased、leukocyte function declined、lack of some microelement、treatment used hormone and immunosuppressor. It is mostly seen in respiratory、urinary tract infection and primary peritonitis.
