[Long-term Effect of the Treatment of IgA Nephropathy by Tonifying Shen, Activating Blood Stasis, Dispelling Wind-Dampness Combined with Western Medicine].

Abstract

Objective To observe the long-term effect of tonifying Shen, activating blood stasis, dispelling wind-dampness (TSABSDWD) combined with Western drugs (WD) for IgA nephropathy. Methods A single center retrospective case-control study was used. The clinical and laboratory examinations, pa- thology of renal biopsy, and treatment programs of IgA nephropathy were obtained from primary IgA ne- phropathy patients (confirmed from renal biopsy at authors' hospital) from Jan 1st, 2008 to Dec 31 , 2008. Patients were assigned to Group A (basic treatment +Chinese herbs) and Group B (basic treatment +Chi- nese herbs + glucocorticoid and/or immune inhibitors). A follow-up visit started from the confirmation of re- nal biopsy to Dec 31, 2008, for at least 12 months. The end point event was defined as entering end stage renal disease (ESRD), estimated glomerular filtration rate (eGFR) decreased by more than 50%, or SCr was doubled. The differences in clinical manifestations, lab indicators and etc. were compared between be- fore treatment and after 1 year of treatment/till the end of follow-ups. The accumulative kidney survival rate was calculated using Kaplan-Meier method. The curve for accumulative kidney survival rate was drawn. Re- sults A total of 219 cases were included, 49 in Group A and 170 in Group B. In Group A, there were 7 pa- tients (14.0%) with Shen deficiency syndrome, 21 cases (43.0%) with Shen deficiency blood stasis syn- drome, 8 (16. 0%) with Shen deficiency wind-dampness syndrome, 13 cases (27. 0%) with Shen deficien- cy blood stasis wind-dampness syndrome. In Group B there were 12 patients (7.1%) with Shen deficiency syndrome, 47 cases (27. 6%) with Shen deficiency blood stasis syndrome, 22 (12.9%) with Shen defi- ciency wind-dampness syndrome, 89 cases (52.4%) with Shen deficiency blood stasis wind-dampness syndrome. No statistical difference in age, sex, or follow-up period between the two groups (P >0.05). Compared with Group A, the disease courser was shorter, 24 h urination increased more, levels of SCr and blood urea nitrogen (BUN) increased higher, plasma albumin decreased lower in Group B (P <0. 05). Compared with before treatment, 24 h urination and counts of urinary red blood cells (RBCs) decreased more in the two groups after 1-year treatment, and decreased further till the end of follow-up (P <0. 05). The total effective rate was 89. 0% (1951219). The total effective rate of Group A was 89. 8% (44/49), with no patient entry into endpoint event. The total effective rate of Group B was 88. 8%(151/170). Totally 5 pa- tients arrived at endpoint event in Group B, 4 in ESRD, 1 with eGFR decreased by more than 50%, or SCr doubled. Compared with Group B, the complete relief rate was higher in Group A (P <0. 01). The accumulative kidney survival rate was 100. 0%, 100. 0%, 98. 0% and 96. 1% in the 219 patients at year 1 , 3, 5, 7, re- spectively using Kaplan-Meier method. Conclusions Programs based on theory of Shen disease wind- dampness in CM and in integrative medicine could be used in treating IgA nephropathy according to differ- ent conditions. Long-term observation showed this program could significantly improve patients' conditions. The 7-year accumulative kidney survival rate was 96. 1%.
