BackgroundDaikenchuto (DKT), a traditional Japanese herbal medicine, is widely used for treatment of gastrointestinal disorders. We evaluated the efficacy and safety of DKT for abdominal bloating in patients with chronic constipation.ObjectiveTo evaluate the efficacy and safety of DKT for the treatment of abdominal bloating.MethodsAfter discontinuing as-needed use of laxatives, 10 patients received oral DKT for 14 days (15 g/d). To evaluate small intestinal bacteria overgrowth (SIBO), a glucose breath test was performed before and after treatment with DKT. Before beginning the treatment, 4 patients (40%) had a diagnosis of SIBO based on a positive glucose breath test result. In both the SIBO and non-SIBO groups, bowel movement frequency and stool form remained unchanged after DKT treatment.ResultsFor all patients, median total Gastrointestinal Symptoms Rating Scale score and the median Gastrointestinal Symptoms Rating Scale indigestion and constipation subscales were significantly decreased, whereas the median visual analog score for decreased abdominal bloating was significantly increased. Improvements of those symptoms were the same in both the SIBO and non-SIBO groups, indicating that DKT does not have effects on small intestine bacteria. No serious side effects were reported.ConclusionsDKT treatment improved quality of life for patients with chronic constipation regardless of the presence of SIBO and showed no effects on small intestine bacteria.

Background There have been very few studies on the association of polypharmacy with clinical course. In this paper, we seek to evaluate the relationship between polypharmacy and hospitalization period. Methods We retrospectively analyzed 322 patients hospitalized from February to September 2017, after excluding short-term and orthopedic cases. Patients with polypharmacy were defined as those who were prescribed more than five drugs at the time of admission. The primary endpoint for all subjects regardless of polypharmacy was the hospitalization period. Using Mann-Whitney U test results, we compared the average number of hospital days between patients with and without polypharmacy. Secondary endpoints were hospitalization period with and without polypharmacy for each disease type. Results The hospitalization period was significantly extended for patients with polypharmacy as compared to those without (31.6 vs. 23.2 days, p: 0.002). Those with an infection had significantly longer hospitalization than those without polypharmacy (27.6 vs. 18.1 days, p: 0.007). Malignancy, heart disease, and cerebrovascular disease did not have a significant effect on hospitalization regardless of polypharmacy. Conclusion Polypharmacy is related to an extended hospitalization period and is found to occur more frequently in patients hospitalized for an infection.
