Purpura patients sensitized about 1/3 of kidney damage, the prognosis depends on the severity of nephropathy, down introduction to TCM etiology and pathology purpura nephritis irritability.
(一) The cause of the disease
1. Exogenous:
(1) wind-heat
Wind-heat evil intrusion, damage to the business of the bloodstains and hair, full of toxic heat, hot spots blood, red blood injured overflow, caused hematuria, purple, or wind-heat evil and the intrinsic heat by the kidney and bladder cause hematuria, edema. Therefore, early disease, more symptoms of exogenous wind-heat, acute onset, moody, often accompanied by itchy skin purple, bright early purple, multi purple red, as Jin Wen, accompanied by vomiting or bleeding from the nose, blood, since both wind and heat infestation.
(2) Blood
Early due to thermal disturbance in contact with blood, spills endosmosis like purple, hematuria, gas falling into the consumption of blood from a wound stasis. Clinical observation, the disease no matter how dialectical because "from the blood stasis," has a different degree of stasis, blood stasis and qi stagnation is the result of a virtual increase.
2. Internal Injury
The imaginary: Mal wind-heat, houses in the kidney, more performance for early renal blood heat, following the outcome of evil fire Shangyin gas consumption, leading to Qi, falling sinister and yang, so the spleen qi deficiency and blood loss. Spleen l lost clear, sealed reservoir renal failure, then proteins and other nutrients from urine leakage.
Form of the disease, especially the loss of Yin because it is very bad six evils of the invasion of evil, the heat of bad blood, disruption of blood contact, forcing blood Wang Xing, excess skin and purple hair, bleeding in the kidney is urinating blood. Heat stasis is the main reason.
(二) Pathology
Henoch-Schonlein glomerulonephritis incidence beginning, many have exogenous history, its pathogenesis in patients with blood heat primarily known intrinsic, complex due to exogenous, food, insect venom, drugs or toxic chemicals such as touch, wind-heat Racing , in contact with blood burns, forcing the blood, skin Spillover, into the stomach hard, worse kidney, therefore, the purple skin, often abdominal pain during, and even then the blood in the stool, blood in the urine, etc; length of the injured kidney yin, causing wang, burning blood contact burns, lesions in contact with the blood of kidney and bladder, and see the purple, hematuria. It follows that, allergic purpura nephritis Wang is both hot evils falling pathological product of the heat loss of body fluid, but still causing purple, hematuria pathogenesis; Diseases long, the loss of abuse of government, can damage the spleen and kidney, spleen and kidney deficiency, lack of temperament, transport dereliction of duty, moisture does not run, renal impairment, can not water, gas lines, causing loss the company gasification bladder opening and closing unfavorable, spleen and kidney deficiency, flood wet body swelling, kidney failure to open and close the retention of urine, thus forming allergic nephritis oliguria erythema, edema and other clinical manifestations.
