Clinical study on Yishen Qufeng Shengshi Recipe () for glomerular proteinuria patients: A randomized controlled trial.

OBJECTIVE: To explore the therapeutic effect of Yishen Qufeng Shengshi Recipe (, YQSR) in patients with glomerular proteinuria METHODS: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group (108 cases) and the control group (37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR (200 mL, twice per day, orally) and losartan (50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment. RESULTS: At the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6% (84/103), 87.4% (90/103), and 92.2% (95/103), respectively, in the treatment group and 47.2% (17/36), 55.6% (20/36), and 61.1% (22/36), respectively, in the control group, with significant difference between the two groups (P<0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months (P<0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group (P<0.05 or P<0.01, respectively) CONCLUSION: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.

[Treatment of Proteinuria in Chronic Glomerular Disease Patients with Pi-Shen Deficiency Complicated Damp-Heat Syndrome by Yishen Qingre Huashi Recipe: a Clinical Study].

OBJECTIVE: To observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS). METHODS: Totally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups. RESULTS: Compared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01). CONCLUSION: YQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.

[Multi-center randomized control study on the effects of syndrome differentiated traditional Chinese medicine therapy on CKD 1-2 with chronic nephritis proteinuria].

OBJECTIVE: To determine the effects of Syndrome Differentiated Chinese Medicine (TCM) Therapy on (CKD) 1-2 stage chronic kidney disease with proteinuria. METHODS: A prospective randomized control study was undertaken in 11 centers. A total of 396 chronic nephritis patients were divided into a treatment group (n=297) and a control group (n=99). Their TCM syndrome was classified as "Qi and Yin Deficiency of spleen and kidney" or "Qi and Yang Deficiency of spleen and kidney", with accompanying syndromes showing as "water and dampness", "damp-heat", and "blood stasis". Patients in the treatment group took a dose of Chinese medicine daily in response to their syndromes, while the controls took 50 mg/d losartan. The course of treatment was 24 weeks. Changes of 24-hour urinary protein excretion and glomerular filtration rate (eGFR) before and after treatments (4, 8, 12, 16, 20, 24 weeks), as well as clinical efficacy (after 4, 16, 24 weeks treatments) were measured. RESULTS: 361 patients were included in the final program participants comply analysis (PPS). Patients in the treatment group showed gradual decreased 24-hour urinary protein excretion, whereas the controls remained unchanged. Significant differences in 24-hour urinary protein excretion appeared between the experimental and control group at week 20 and 24 (P<0.05). eGFR decreased in all of the patients after treatments (P=0.0014). At three follow-up points, patients in the treatment group had higher eGFR than the controls, but without statistical significance (P>0.05). Significant differences in clinical remission rate, marked effect rate and total effective rate were observed between the treatment and control groups at week 24 (P<0.001). CONCLUSION: Syndrome differentiated TCM therapy can reduce the level of proteinuria in CKD 1-2 nephritis patients, promoting clinical effectiveness and protecting renal functions.

Optimized project of traditional Chinese medicine in treating chronic kidney disease stage 3: a multicenter double-blinded randomized controlled trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Stage 3 is the key phase of chronic kidney disease. Traditional Chinese medicine (TCM) has been used for the treatment of chronic kidney disease. But a large sample trial is desirable. MATERIALS AND METHODS: A total of 578 Chinese patients with primary glomerulonephritis in CKD stage 3 were randomly assigned to three groups: patients received TCM (TCM group), benazepril (Ben group), TCM combined with benazepril (TCM+Ben group). Patients were followed up for 24 weeks. The primary endpoint was the time to the composite of 50% increased of serum creatinine, end stage renal disease or death. RESULTS: eGFR in the TCM and the TCM+Ben group were improved (week 24 vs. baseline, P<0.05) while eGFR in the Ben group was decreased (week 24 vs. baseline, P>0.05). 24h urinary protein excretion (UP) and urinary albumin/creatinine (UAlb/Cr) were decreased in the TCM+Ben (week 24 vs. baseline, P<0.05) and the Ben group (week 24 vs. baseline, P>0.05). UP and UAlb/Cr were increased in the TCM group to week 12, then were stable (week 24 vs. baseline, P<0.05). The hemoglobin in the TCM group was also improved (week 24 vs. baseline, P<0.05). The accumulative survival rate in the TCM+Ben group was higher than that in the TCM group and the Ben group (P=0.044). Side effects in the TCM group were the lowest in these groups (P<0.05). The patients with dry cough in the TCM+Ben group and the Ben group were increased as compared with the TCM group (P<0.05). Hyperkalemia happened less frequently in the TCM group as compared with the other two groups (P=0.052). CONCLUSIONS: For the patients with CKD stage 3, TCM can improve eGFR and hemoglobin with lower side effects. Benazepril significantly decreased the proteinuria. Chinese medicine integrated with benazepril can ameliorate renal function and decrease proteinuria synergistically.
