Effects of a Herbal Medicine, Yukgunja-Tang, on Functional Dyspepsia Patients Classified by 3-Dimensional Facial Measurement: A Study Protocol for Placebo-Controlled, Double-Blind, Randomized Trial

Efficacy of a Traditional Herbal Formula, Banha-Sasim-Tang in Functional Dyspepsia Classified as Excess Pattern

This study evaluated the efficacy and safety of Banha-sasim-tang (BST) in patients with functional dyspepsia (FD). BST (Banxia-xiexin-tang in traditional Chinese medicine and Hange-shashin-to in Kampo medicine) is traditionally prescribed for the treatment of dyspepsia with epigastric stiffness and gastric fullness in China, Japan, and Korea. Patients with FD were randomly administered an oral dose (10 g) of BST syrup or placebo, twice a day for 4 weeks. The primary outcome was the symptom checklist part of the Nepean dyspepsia index (NDI). The secondary outcomes were the quality of life (QoL) part of the NDI, functional dyspepsia-related QoL (FD-QoL), and visual analog scale (VAS). A total of 60 patients with FD were screened, and 50 were randomized into BST group (n = 25) and placebo group (n = 25). Two patients in the placebo group withdrew before the start of the treatment. Administration of BST syrup resulted in improvement in the symptom-related NDI score in the BST group compared with that in the control group; however, the difference was not significant. BST syrup significantly improved "fullness after eating" index of NDI at follow-up time point (2.88 ± 2.65 vs 4.78 ± 2.69, p = 0.0081). In the total score of the QoL section of the NDI and FD-QoL scales, there was no significant improvement in the BST group compared to that in the placebo group. With regard to improvement in overall FD symptoms, the VAS scale showed improvement in both groups, but the difference was not significant. Interestingly, follow-up investigation showed a significantly beneficial effect of BST on FD symptoms, when compared to placebo. Significant improvement observed in VAS score (39.60 ± 22.29 vs 52.17 ± 20.55, p = 0.048). This indicated that the effect of BST lasted even after the completion of the medication regimen. Overall, our data suggest that while BST showed no significant improvement in the symptom-related NDI score and the QoL related scores in NDI and FD-QoL after 4 weeks of treatment, it effectively improved the VAS score and fullness after eating-related symptoms in the follow-up visit.

Quality of life and its influencing factors in elderly patients with functional dyspepsia in a tertiary hospital in Jinhua

BACKGROUND

Functional dyspepsia (FD) is a clinically common disease that mainly occurs in middle-aged and elderly patients. It is now believed that mental factors and somatization are risk factors affecting the quality of life of elderly FD patients. Because of the uneven distribution of medical resources in China, the quality of life in elderly Chinese patients with FD is insufficiently understood. Therefore, analyzing the factors influencing their quality of life is particularly necessary.

AIM

To explore the quality of life and its influencing factors in elderly patients with FD in a tertiary hospital in Jinhua.

METHODS

A total of 134 elderly patients with FD admitted to our hospital from June 2017 to August 2019 were selected as study subjects. Quality of life scale, mental and psychological status scale, and health behavior self-efficacy scale were used for evaluations, and the factors influencing the quality of life of elderly FD patients were analyzed.

RESULTS

The total score of the Functional Digestive Disorders Quality of Life (FDDQL) questionnaire in the elderly patients with FD was 57.62 ± 8.16; the score of daily activities was least influenced (75.48 ± 7.23), while the score of healthy feeling was most seriously influenced (45.61 ± 9.57), followed by the score of disease control (47.38 ± 10.36). FDDQL scores differed significantly between patients with different genders, Self-rating Anxiety Scale (SAS) scores, Self-rating Depression Scale (SDS) scores, self-efficacy, drinking history, disease course, residence, symptom severity, mood self-regulation, and regular exercise (P < 0.05 or P < 0.01), but did not between patients with different body mass indexes (BMI). FDDQL scores were positively correlated with gender, self-efficacy, BMI, drinking history, disease course, residence, and regular exercise (r = 0.147-0.215, P < 0.05), but negatively correlated with SAS and SDS scores, symptom severity, and mood self-regulation [r = -0.765-(-0.284), P < 0.05]. Multiple regression analysis showed that anxiety, symptom severity, disease course, self-efficacy, and depression were the factors influencing the quality of life of elderly FD patients.

CONCLUSION

There are many factors affecting the quality of life of elderly FD patients, with anxiety, severity of symptoms, course of disease, self-efficacy, and depression being important risk factors. Reasonable intervention targeting the above risk factors should be taken to improve the quality of life of these patients in clinical work.

An Herbal Medicine, Yukgunja-Tang is more Effective in a Type of Functional Dyspepsia Categorized by Facial Shape Diagnosis: A Placebo-Controlled, Double-Blind, Randomized Trial

INTRODUCTION

Functional dyspepsia (FD) is a functional gastrointestinal disorder characterized by persistent upper dyspeptic symptoms without organic lesions. There is no standard therapy for FD. Yukgunja-tang (YGJT) is an herbal medicine used for treating upper gastrointestinal symptoms in Asia. Studies on the effect of YGJT on FD have been conducted. However, the results were inconsistent. In Hyungsang medicine, traditional Korean medicine, FD patients are classified into bladder body (BB) or gallbladder body (GB) subtypes by the shape and angle of their faces. Each subtype may have different characteristics, physiology, and pathology of the same disease. YGJT is more effective for patients with BB subtype. The three-dimensional facial shape diagnostic system (3-FSDS) was shown to be effective in diagnosing BB or GB subtypes. This study aimed to investigate the effect of YGJT on FD patients classified using the 3-FSDS.

MATERIALS AND METHODS

The current study was a placebo-controlled, double-blinded, randomized, two-center trial. Eligible patients were diagnosed with either BB or GB FD subtype using the 3-FSDS. Ninety-six participants (48 BB and 48 GB subtypes) were randomly allocated to treatment or control groups in a 2:1 ratio. YGJT or placebo was administered for eight weeks. The primary outcome was assessed using the total dyspepsia symptom scale (TDS), while the secondary outcomes were assessed using the single dyspepsia symptom scale (SDS), proportion of responders, visual analog scale, Nepean dyspepsia index, functional dyspepsia-related quality of life, and spleen qi deficiency questionnaire.

RESULTS AND DISCUSSION

The result of TDS showed the superior effect of YGJT on BB over GB subtype. The subgroup analysis of TDS and SDS scores showed the superior effect of YGJT over placebo. Other outcome variables did not show any significant differences between groups.

CONCLUSION

YGJT may be considered for FD patients diagnosed with BB subtype using 3-FSDS.

Safety and Efficacy of Ferula asafoetida in Functional Dyspepsia: A Randomized, Double-Blinded, Placebo-Controlled Study

Despite the availability of various synthetic drugs for the treatment of functional dyspepsia (FD), the side effects and their cost have always created a great interest in the search for novel natural alternatives for the management of gut disorders. The present contribution reports the safety and efficacy of the kitchen spice asafoetida (Ferula asafoetida) in FD for the first time. In the double-blinded, placebo-controlled study, 43 subjects diagnosed to have moderate to severe discomforts of nonulcer FD were randomized to receive hard-shell capsules (250 mg × 2/day) of either placebo (n=22) or a food-grade formulation of asafoetida (Asafin) (n=21) for 30 days. When evaluated by a set of validated indexing tools (GSRS, GDSS, and NDI), almost 81% in the Asafin group showed significant (p < 0.01) improvement in the overall score and quality of life as compared to the placebo. At the end of the study, 66% of subjects in the Asafin group remained symptoms-free. Although the symptoms score improved significantly in both the groups (from -5.67 to -25.29 in Asafin group versus -1.55 to -6.0 in the placebo; p ≤ 0.001), the relative percentage of subjects in the Asafin group with more than 80% reduction in various symptoms were: bloating (58%), appetite (69%), postprandial fullness (74%) motion sickness (75%), and digestion (77%) as compared to less than 10% nonspecific improvement in the placebo group. All the subjects remained safe with no adverse events or variations in haematological and biochemical parameters. The study was registered at http://ctri.nic.in/ (CTRI/2018/ 01/011149).
