RESUMO
Renal hematuria is caused by glomerular damage and basement membrane rupture due to coagulation dysfunction， ischemia and hypoxia， and immune function damage， resulting in red blood cells exuding through glomerular filtration membrane and excreting with urine. It is mainly manifested as microscopic and macroscopic hematuria. Among them， microscopic hematuria is characterized by microscopic urine sediment examination， there are three or more red blood cells per high-power microscopic field. Traditional Chinese medicine （TCM） believes that the pathogenesis of renal hematuria always belongs to ''asthenia in origin and sthenia in superficiality''， and ''asthenia in origin'' is caused by the deficiency of the three viscera of the lung， spleen， and kidney， while ''sthenia in superficiality'' is caused by the combination of dampness and blood stasis and the external disturbance of wind pathogens. The key pathogenesis features are ''deficiency， dampness， heat， blood stasis， and wind''. After consulting the TCM literature related to renal hematuria， the author found that the common syndrome types of renal hematuria in clinical practice were the deficiency of both Qi and Yin， the deficiency of both Yin and fire， the unsteadiness of kidney Qi， the deficiency of spleen and kidney Yang， the wind heat hurting the collateral， the dampness-heat blocking， and the blood stasis and internal resistance. The commonly used classical or temporal prescriptions included Shenqi Dihuangtang（参芪地黄汤）， Zhibai Dihuangtang（知柏地黄汤）， Wubi Shanyaowan（无比山药丸）， Jisheng Shenqiwan（济生肾气丸）， Sishenwan（四神丸）， Yinqiaosan（银翘散）， Bazhengsan（八正散）， Sanrentang（三仁汤）， Xuefu Zhuyutang（血府逐瘀汤）， Danggui Shaoyaosan（当归芍药散）， Xiaoji Yinzi（小蓟饮子）， Buzhong Yiqitang（补中益气汤）， et al. Self prepared prescriptions mainly include Tongluo Ningxue prescription （通络宁血方）， Qingre Zhixue prescription（ 清热止血方） and Wuteng Tongluo drink （五藤通络饮）. The traditional Chinese medicine is commonly used for the treatment of Xueniaoling granules（血尿灵冲剂）， Xueniaoan capsules（血尿安胶囊）， Ningmitai capsules（宁泌泰胶囊）， Huangkui capsules（黄葵胶囊） and Yishen nixuexiao granules（益肾溺血消颗粒）， which constantly enriched the treatment of renal hematuria. The combination of TCM and western medicine has obvious advantages. The treatment of renal hematuria in clinical practice often combines with modern medical methods， which has a good therapeutic effect on the improvement of symptoms and indicators of renal hematuria. At present， many doctors have made in-depth exploration on the etiology， pathogenesis， and clinical treatment of renal hematuria， but few scholars have made detailed induction and collation in recent years. Therefore， the author has collated the clinical data on the treatment of renal hematuria with TCM in the past ten years， and reviewed it from the aspects of etiology， pathogenesis， and clinical research， to provide useful references for clinical intervention and delay the progress of renal disease.
RESUMO
Based on the "warming the injured and activating the relaxed" theory, this article explored the pathogenesis and treatment of renal hematuria. The pathogenesis of renal hematuria mainly lies in the deficiency of spleen and kidney, blood stasis and qi obstruction, and the internal channeling of pathogenic wind. The author put forward that "warming the injured and activating the relaxed" as the general treatment principle of renal hematuria. In clinical practice, the main treatment methods should be to cultivate and supplement the spleen and kidney, promote blood circulation and expel wind, warm and supplement the spleen and kidney to restore the fixation of the qi of the viscera, promote blood circulation and remove blood stasis to remove the blood stasis outside the blood overflow vessels, and eliminate pathogenic wind to prevent and stop the disturbance of Jingguan. In accordance with the treatment of syndrome differentiation, it emphasized both nourishing and dispelling pathogenic factors, and according to the degree of deficiency of zang-fu organs and the retention of pathogenic factors, and listed the related therapeutic drugs, which provided a new idea and method for the clinical application of TCM in the treatment of renal hematuria.
RESUMO
Objective:To investigate the incidence and clinical characteristics of renal involvement with Omicron coronavirus infection in age-based stratified patients.Methods:The first batch of 430 convalescent patients with Omicron coronavirus treated in Tianjin First Central Hospital from January 21, 2022 to March 7, 2022 were enrolled in this study. The baseline information, vaccination status and laboratory examination information of patients were extracted in order to analyze the incidence of renal involvement in age-based stratified patients. Multivariate Logistic regression analysis was conducted to determine the risk factors of renal involvement in different age groups.Results:Excluding those younger than 1 year old and those with a history of chronic kidney disease, a total of 421 patients were included. There were 184 males and 237 females with an average age of (36.65±21.28) years. The types of renal involvement included pathological tubular urine (28.9%), proteinuria (16.9%), renal hematuria (14.7%), a slight decrease of estimated glomerular filtration rate (eGFR, 9.3%), renal glycosuria (0.5%). According to their age, all patients were divided into three groups: 113 cases of ≤ 18 years old, 244 cases of 19-59 years old and 64 cases of ≥ 60 years old. Significant difference was founded in the incidence of renal involvement among the three groups. The incidence of proteinuria, pathological tubular urine and slight decline of eGFR in the ≥ 60 years old group were significantly higher than those in the ≤ 18 years old group [28.1% (18/64) vs. 8.0% (9/112), 42.2% (27/64) vs. 19.6% (22/112), 34.9% (22/63) vs. 6.2% (7/113), respectively, all P < 0.01]. The incidence of slight decline of eGFR was significantly higher than that in 19-59 years old group [34.9% (22/63) vs. 4.1% (10/243), P < 0.01]. Multivariate Logistic regression analysis showed that age was significantly correlated with renal involvement after adjusting for the baseline situation, serological indexes and Omicron infection related indexes [odds ratio ( OR) = 1.059, 95% confidence interval (95% CI) was 1.021-1.097, P = 0.002]. Compared with the group ≤ 18 years old, the risk of renal involvement in the group ≥ 60 years old was significantly increased ( OR = 26.245, 95% CI was 1.357-507.458, P = 0.031). Age ≥ 60 years old was an independent risk factor for renal involvement with Omicron coronavirus infection. Conclusions:Although a low incidence of severe cases in Tianjin first batch of 430 patients with Omicron coronavirus infection, there is still a high incidence of renal involvement. Advanced age is the risk factor of renal involvement. We should pay more attention to the renal involvement of elderly with Omicron coronavirus infection.
