Topical therapy with rhubarb navel plasters in patients with chronic constipation: Results from a prospective randomized multicenter study

ETHNOPHARMACOLOGICAL RELEVANCE

Constipation is a functional gastrointestinal disorder and one of the most prevalent conditions encountered in primary care settings. Rhubarb navel dressings have been used for more than 2,000 years in Chinese medicine to treat constipation. However, the effect of topical rhubarb administration has still not been well recognized and this strategy is not yet established as an evidence-based approach.

AIM OF THE STUDY

In this study, we performed a prospective multicentric randomized controlled trial to evaluate the efficacy and safety of rhubarb navel plasters for patients with chronic constipation.

MATERIALS AND METHODS

A total of 374 patients from six teaching hospitals were prospectively included between 09/2016 and 10/2017 in the study based on Rome III criteria. All participants were randomly assigned (1:1) into verum/placebo group and given either Rheum officinale rhubarb powder or a placebo flour stick on the navel for 6 h/day/8 days. Primary outcome measures were the Cleveland Constipation Score (CCS) for the feces condition and Bristol Stool Scale (BSS) for stool consistency and 24 h defecation frequency.

RESULTS

The groups demonstrated no statistical differences in demographic data, clinical diagnoses and concomitant medication at baseline. In patients treated with the verum CCS was 5.61 (day 8, 95% CI 5.15-6.07) compared to 8.62 (95% CI 8.07-9.18) in placebo-treated controls (P < 0.001). The mean change of CCS at the end of treatment (day 8 versus [vs] day 0) was 6.04 in verum-treated vs 2.73 in placebo-treated controls (P < 0.001). Also 24 h defecation frequency (BSS) showed superior results (day 5: 0.84 vs 0.62, 95% CI 0.67-0.80, P < 0.001; day 6: 0.82 vs 0.60, 95% CI 0.64-0.78, P < 0.01 and day 8: 0.82 vs 0.60, 95% CI 0.64-0.78, P < 0.01) and better BSS type classification during treatment than controls (P < 0.05). No significant differences in adverse events between both groups became obvious.

CONCLUSION

Rhubarb navel plaster administration over an 8-day-treatment period resulted in significantly improved bowel function as demonstrated by the CCS, 24 h defecating frequency and BSS. Our results suggest that rhubarb navel plasters represent a feasible, safe and efficient application route for the treatment of patients suffering from chronic constipation.

An herbal-compound-based combination therapy that relieves cirrhotic ascites by affecting the L-arginine/nitric oxide pathway: A metabolomics-based systematic study

ETHNOPHARMACOLOGICAL RELEVANCE

Traditional Chinese medicine boasts a 440-year-long history of treating refractory ascites via combinations of herbal medicines, called formulae. Xiaozhang Tie (XT) is a proprietary herbal-compound-based formula that has been proven to be very effective in the treatment of cirrhosis-associated ascites in clinical practice, but the mechanism of action of XT remains unknown.

AIM OF THE STUDY

In this study, we used a metabolomics-based systematic method to elucidate the mechanism of XT in the treatment of cirrhotic ascites.

METHODS

Decompensated liver cirrhosis was induced in rats by intraperitoneal injection of Carbon tetrachloride (CCl₄). Ultra performance liquid chromatography-mass spectrometry (UPLC-MS) combined with pattern recognition approaches were used to determine differentiating metabolites relevant to XT treatment. Biomarkers were further validated by a targeted quantitative method and by the results from serum and urine analyses. Pathway analysis and correlation network construction were used to reveal the therapeutic targets associated with XT treatment, and the potential mechanisms were verified by the results from biochemical, histopathological and immunohistochemical assays.

RESULTS

XT synergistically mediated the abnormalities of amino acid metabolic pathways in cirrhotic rats. XT significantly elevated the arginine levels, reduced the serum nitric oxide (NO) levels and alleviated the gastrointestinal motility disorder of cirrhotic rats. This effect of XT has been confirmed by the inhibition of the activities of inducible NO synthase and neuronal NO synthase in the small intestine.

CONCLUSIONS

These results reveal that XT promotes gastrointestinal motility by acting on multiple targets in multiple pathways, of which the L-arginine/NO pathway is most affected.

Efficacy and safety of umbilical therapy with the traditional Chinese medicine formulation Lishui Xiaogu cataplasm for cirrhotic ascites: protocol for a randomized controlled trial

BACKGROUND

Ascites is one of the most common complications of cirrhosis. Umbilical therapy with traditional Chinese medicines has been increasingly prescribed to treat cirrhotic ascites. However, high-quality evidence from clinical trials supporting such application of traditional Chinese medicines remains limited. Therefore, we designed a clinical trial to evaluate the efficacy and safety of umbilical therapy with the Lishui Xiaogu cataplasm formulation applied to treat cirrhotic ascites.

METHODS/DESIGN

This ongoing study is a double-blind, randomized, parallel, placebo-controlled trial. A total of 82 patients will be recruited and randomly assigned to either a treatment group or a placebo group, in a 1:1 ratio. The treatment group will receive umbilical therapy with the Lishui Xiaogu cataplasm plus red light irradiation along with conventional treatment; the placebo group will receive umbilical therapy with a placebo cataplasm plus red light irradiation along with conventional treatment. Interventions for both groups will be administered once daily for up to 10 days, with a 30-day follow-up after the last treatment. The primary efficacy measurement will be ascites depth. Secondary efficacy measurements will include abdominal perimeter, weight, urine volume, the symptomatic score of traditional Chinese medicine, and the Chronic Liver Disease Questionnaire. Adverse events will also be reported.

DISCUSSION

This randomized trial will be the first rigorous study designed to evaluate the efficacy and safety of umbilical therapy with Lishui Xiaogu cataplasm applied for cirrhotic ascites.

Influence of Fuzheng Huayu Tablet on mental state and social function of patients with post-hepatitis B liver cirrhosis

OBJECTIVE

To observe the influence of Fuzheng Huayu Tablet on mental state and social activity of patients with post-hepatitis B liver cirrhosis (LC-HB).

METHODS

Adopting grouped randomized double-blinded control method, 180 LC-HB patients in 3 research centers were distributed to 2 groups, the treated group and the control group, 90 in each group. Patients in the treated group were administered with FZHYT; while those in the control group treated with conventional therapy combined with placebo, the course for all patients were 6 months. Their mental state and social activity were evaluated before treatment, after 3 months' treatment and at terminal of the 6-month therapeutic course by estimating with Zung self-rating anxiety scale (SAS), self-rating depression scale (SDS) and social deficit screening scale (SDSS). Additionally, the basic demographic materials, liver function, cirrhosis index, hepatic and splenic images, blood coagulation function, etc. in the patients were tested and compared as well.

RESULTS

As compared with before treatment, the normal rate of SAS and SDS scores increased and the social deficit rate decreased in the treated group significantly after treatment, showing statistical significance (P<0.05 or P<0.01); while in the control group, change was only shown in the social deficit (P<0.01), inter-group comparisons after treatment showed significant differences in all the three indexes (P<0.05 or P<0.01). Additionally, after treatment, levels of liver function, cirrhosis, blood coagulation function and splenomegaly in the treated group were all improved significantly P<0.05 or P<0.01), and the improvements were better than those in the control group (P<0.01) in levels of total bilirubin (TBIL), albumin (ALB), type IV collagen (IV-C), prothrombin time (PT), prothrombin activity (PTA).

CONCLUSION

Most patients of LC-HB have mental disturbance and social activity deficit, which could definitely be improved by intervention with Chinese FZHYT.

Ascites and spontaneous bacterial peritonitis: an Asian perspective

Ascites is the most common complication of liver cirrhosis, and it develops as a consequence of portal hypertension and splanchnic vasodilatation. Depending on severity, management of ascites consists of diverse strategy, including dietary sodium restriction, diuretic therapy, repeated large-volume paracentesis with albumin infusion, transjugular intrahepatic portosystemic shunt, and liver transplantation. Recently, advances in medical therapy have been made with satavaptan, a V2 receptor antagonist, vasoconstrictors, such as clonidine, midodrine, or terlipressin, and other categories of drugs, including docarpamine and Chinese herbs. These drugs may serve as useful adjuncts to conventional diuretics in the management of ascites. Besides ascites itself, serious complications, such as spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome, frequently ensue in decompensated cirrhosis. SBP develops from the translocation of bacteria from the intestine, and successful management with early diagnosis and treatment with proper prevention in patients of high risk is necessary. In summary, ascites is a starting point for more serious complications in liver cirrhosis. Although liver transplantation is the fundamental treatment, it is not always feasible, and consequently various means of treatment should be used. Further study, particularly in Asia where hepatitis B virus-related cirrhosis is predominant, is warranted to improve the clinical outcome.
