[Effects of Chinese herbal enema therapy combined basic treatment on BUN, SCr, UA, and IS in chronic renal failure patients].

OBJECTIVE

To assess the clearance role and safety of Chinese herbal enema therapy (CHET) in clearing enterogenic uremic toxins in chronic renal failure (CRF) patients, thus providing evidence for further optimizing the comprehensive treatment.

METHODS

Using nonrandomized concurrent control trial, 96 CRF inpatients of Department of Nephropathy, Guangdong Provincial Hospital of Traditional Chinese Medicine, from March 2010 to December 2010 were assigned to the treatment group and the control group according to their willingness. All patients were treated with basic treatment referring to clinical plans in the non-dialysis phase, while those in the treatment group were additionally treated with CHET, once daily, 2 weeks as one therapeutic course. The symptoms, serum enterogenic uremic toxin levels [including indoxyl sulfate (IS), blood urea nitrogen (BUN), and uric acid (UA)], and serum creatinine (SCr) were observed in the two groups between and after treatment. The adverse reactions were also monitored during the treatment period. The clinical efficacy and safety were also assessed.

RESULTS

Totally 84 patients completed this clinical observation, 48 in the treatment group and 36 in the control group. The levels of SCr, BUN, and IS were obviously lower in the treatment group after treatment, showing statistical difference when compared with before treatment (P<0.01). There was no statistical difference in each index in the control group between before and after treatment (P>0.05). The post-treatment the IS level was lower in the treatment group than in the control group with statistical difference (P<0.05). Symptoms like fatigue, soreness of waist and knees, constipation and edema were partially relieved in both groups (P<0.05, P<0.01). The ratios of anorexia and nausea in patients of the treatment group was lowered after treatment (P<0.05). Besides, patients in the treatment group could defecate for more than once daily during the enema treatment period, dominated as rotten and soft feces. No severe adverse event occurred during the treatment period.

CONCLUSION

CHET combined basic treatment could lower the serum levels of enterogenic uremic toxins (IS and BUN) of CRF patients in a short period.
