Effects of Bifidobacterium longum CLA8013 on bowel movement improvement: a placebo-controlled, randomized, double-blind study. BIOSCIENCE OF MICROBIOTA, FOOD AND HEALTH 2023; 42:213-221. [PMID: 37404567 PMCID: PMC10315193 DOI: 10.12938/bmfh.2022-066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 03/18/2023] [Indexed: 07/06/2023]
Abstract
A placebo-controlled, randomized, double-blind study was conducted to evaluate the effect of taking 25 billion colony-forming units of heat-killed Bifidobacterium longum CLA8013 over 2 weeks on bowel movements in constipation-prone healthy individuals. The primary endpoint was the change in defecation frequency between the baseline and 2 weeks after the intake of B. longum CLA8013. The secondary endpoints were the number of days of defecation, stool volume, stool consistency, straining during defecation, pain during defecation, feeling of incomplete evacuation after defecation, abdominal bloating, fecal water content, and the Japanese version of the Patient Assessment of Constipation Quality of Life. A total of 120 individuals were assigned to two groups, 104 (control group, n=51; treatment group, n=53) of whom were included in the analysis. After 2 weeks of consuming the heat-killed B. longum CLA8013, defecation frequency increased significantly in the treatment group compared with that in the control group. Furthermore, compared with the control group, the treatment group showed a significant increase in stool volume and significant improvement in stool consistency, straining during defecation, and pain during defecation. No adverse events attributable to the heat-killed B. longum CLA8013 were observed during the study period. This study revealed that heat-killed B. longum CLA8013 improved the bowel movements of constipation-prone healthy individuals and confirmed that there were no relevant safety issues.

Association of Stool Frequency and Consistency with the Risk of All-Cause and Cause-Specific Mortality among U.S. Adults: Results from NHANES 2005-2010. Healthcare (Basel) 2022; 11:healthcare11010029. [PMID: 36611489 PMCID: PMC9818668 DOI: 10.3390/healthcare11010029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/15/2022] [Accepted: 12/19/2022] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Prior studies on the relationship between bowel health and mortality have generally focused on the individual association of stool frequency or consistency with mortality but did not present a joint association. Therefore, we aimed to systematically evaluate the individual and joint associations of stool frequency and consistency with all-cause and cause-specific mortality in this study. METHODS A total of 14,574 participants from the National Health and Nutrition Examination Survey 2005-2010 were incorporated in this analysis. Survey sample-weighted Cox proportional hazards models adjusted for potential confounders were used to estimate hazard ratios (HRs) between bowel health measures and mortality risks. RESULTS During a median of 7.6 years of follow-up, 1502 deaths occurred, including 357 cancer deaths and 284 cardiovascular disease (CVD) deaths. The bowel habit of the most participants was 7 times/week (50.7%), and the most common type was "Like a sausage or snake, smooth and soft" (51.8%). Stool frequency displayed a parabolic relationship with all-cause mortality, and less than 7 times/week is a significant risk factor for mortality (HR for 1 time/week: 1.43, p-values = 0.04. HR for 6 times/week: 1.05, p-value = 0.03). Analyzing the joint association of stool frequency and consistency on mortality clarified the limitations of only inspecting the effects of either individual factor. Compared with 7 times/week of normal stool, infrequent soft stools at 4 times/week were associated with 1.78-, 2.42-, and 2.27-times higher risks of all-cause, cancer, and CVD mortality, respectively. CONCLUSION Analyses of bowel health should consider the joint effects of stool frequency and stool consistency. Self-appraisal of stool frequency and consistency may be a simple but useful tool for informing about major chronic illnesses.

Effect of Fermented Red Ginseng Concentrate Intake on Stool Characteristic, Biochemical Parameters, and Gut Microbiota in Elderly Korean Women. Nutrients 2022; 14:nu14091693. [PMID: 35565660 PMCID: PMC9105854 DOI: 10.3390/nu14091693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 04/15/2022] [Accepted: 04/18/2022] [Indexed: 12/05/2022] Open
Abstract
Fermented red ginseng (FRG) has been used as a general stimulant and herbal medicine for health promotion in Asia for thousands of years. Few studies have investigated the effects of FRG containing prebiotics on the gut microbiota. Here, 29 Korean women aged ≥ 50 years were administered FRG for three weeks to determine its effect on stool characteristics, biochemical parameters, and gut microbiome. Gut microbial DNA was subjected to 16S rRNA V3–V4 region sequencing to assess microbial distribution in different stages. Additionally, the stool consistency, frequency of bowel movements, and biochemical parameters of blood were evaluated. We found that FRG intake improved stool consistency and increased the frequency of bowel movements compared to before intake. Biochemical parameters such as glucose, triglyceride, cholesterol, low-density lipoprotein cholesterol, creatinine, alkaline phosphatase, and lactate dehydrogenase decreased and high-density lipoprotein cholesterol increased with FRG intake. Gut microbiome analysis revealed 20 specific bacteria after three weeks of FRG intake. Additionally, 16 pathways correlated with the 20 specific bacteria were enhanced after red ginseng intake. In conclusion, FRG promoted health in elderly women by lowering blood glucose levels and improving bowel movement frequency. The increase in bacteria observed with FRG ingestion supports these findings.

Bristol Stool Scale as a Determinant of Hepatic Encephalopathy Management in Patients With Cirrhosis. Am J Gastroenterol 2022; 117:295-300. [PMID: 34738545 PMCID: PMC8816826 DOI: 10.14309/ajg.0000000000001550] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 09/27/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Bowel movement (BM) frequency is used to titrate lactulose for hepatic encephalopathy (HE). However, stool consistency using the Bristol stool scale (BSS, 0-7) is often ignored. METHODS The study included pre-BSS and post-BSS cohorts. BSS was incorporated into decision-making after training in outpatients with cirrhosis. Two to 3 BMs/d and BSS 3-4 were considered normal, whereas the rest were considered high or low; concordance between the metrics was evaluated. Medication changes and 6-month admissions were compared between this group (post-BSS) and a comparable previous group (pre-BSS). Concordance and regression analyses for all-cause admissions and HE-related admissions were performed, and comparisons were made for HE-related medication stability. In the longitudinal analysis, an outpatient group seen twice was analyzed for BSS and BMs. RESULTS In the post-BSS cohort, 112 patients were included with only 46% BSS and BMs concordance and modest BSS/BMs correlation (r = 0.27, P = 0.005). Compared with a pre-BSS cohort (N = 114), there was a lower 6-month total (4% vs 0.36%, P < 0.001) or HE-related admission (1% vs 0.12%, P = 0.002). Regression showed model for end-stage liver disease (odds ratio [OR]: 1.10, P = 0.003) and pre-BSS/post-BSS (OR: 0.04, P < 0.001) for all-cause admissions and HE (OR: 3.59, P = 0.04) and preera/postera (OR: 0.16, P = 0.02) for HE-related admissions as significant. HE medication regimens were more stable post-BSS vs pre-BSS (32% vs 20%, P = 0.04), which was due to patients with BSS > BMs (P = 0.02). In the longitudinal analysis, 33 patients without medication changes or underlying clinical status changes were tested 36 ± 24 days apart. No changes in BSS (P = 0.73) or BMs (P = 0.19) were found. DISCUSSION BSS is complementary and additive to BM frequency, can modulate the risk of readmissions and stabilize HE-related therapy changes in outpatients with cirrhosis, and could help personalize HE management.

Effects of ID-HWS1000 on the Perception of Bowel Activity and Microbiome in Subjects with Functional Constipation: A Randomized, Double-Blind Placebo-Controlled Study. J Med Food 2021; 24:883-893. [PMID: 34406877 DOI: 10.1089/jmf.2020.4746] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/11/2022] Open
Abstract
During constipation, indigestible foods, such as probiotics, prebiotics, and dietary fiber, may improve the bowel environment and activity. In this randomized, double-blind, and placebo-controlled study, the effects of ID-HWS1000, composed of Lactobacillus and Bifidobacterium species, xylooligosaccharide, and dietary fiber, were evaluated to determine whether it improves the perception of bowel activity or cause changes in the gut microbiome. Thirty Korean adults with "functional constipation" according to the Rome III criteria were randomly assigned to the following groups: 20 in the ID-HWS1000 group and 10 in the placebo group. ID-HWS1000 or the placebo was consumed by the participants for 4 weeks. To assess the changes in the perception of bowel activity, clinical data and gut microbiome analyses were conducted before and after the experiment. There were significant differences between the groups in the response to 9 of the 12 survey questions (the number and duration of bowel movements, amount of feces, number of irritant bowel movements, number of times bowel movements felt incomplete, shape of the feces, amount of gas in the gut, discomfort after defecation, and discomfort owing to constipation) (P < .05). There was a decrease in the proportion of Firmicutes (Ruminococcaceae and Lachnospiraceae) and an increase in Bacteroidetes (Bacteroidaceae) (P < .05). Moreover, ID-HWS1000 directly improved the discomfort associated with bowel movements, decreased the proportion of Lachnospiraceae, and increased the proportion of Bacteroidaceae. These results confirmed that ID-HWS1000 improves the perception of bowel activity and exerts positive changes in individuals with functional constipation.

Effects of citrus juice fermented with Lactobacillus plantarum YIT 0132 on Japanese cedar pollinosis during probiotic consumption: an open study. BIOSCIENCE OF MICROBIOTA FOOD AND HEALTH 2020; 39:137-144. [PMID: 32775132 PMCID: PMC7392906 DOI: 10.12938/bmfh.2019-017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Accepted: 02/23/2020] [Indexed: 11/28/2022]
Abstract
Certain strains of lactic acid bacteria (LAB) have beneficial effects on Japanese cedar pollinosis (JCPsis), which is a major concern in Japan. Heat-killed Lactobacillus
plantarum YIT 0132 (LP0132), selected for its ability to induce interleukin (IL)-10, has been shown to suppress JCPsis symptoms. Lactobacillus casei
Shirota (LcS), a popular probiotic, potentially induces a high level of IL-12 and is reported to delay the onset of JCPsis symptoms. However, it is unclear whether a combination of
different types of LAB exerts additional effects without interfering with the benefits of each individual LAB. Thus, we conducted a pilot study to investigate the effects of
LP0132-fermented citrus juice on JCPsis during simultaneous consumption of LcS-fermented milk. Fifty-nine subjects with JCPsis were allocated to two groups after a 2-week
preconsumption period: one group consumed LP0132-fermented citrus juice and LcS-fermented milk (LcS+LP0132 group) for 12 weeks, while the other consumed LcS-fermented milk alone
(LcS group). JCPsis symptoms, JCPsis-associated quality of life (QOL) impairment, and bowel movements were assessed by questionnaires. Compared with the LcS group, the LcS+LP0132
group showed significant alleviation of total symptoms and total ocular symptoms during the consumption period, as well as relief of impaired QOL. Bowel movements were
significantly improved during the consumption period compared with the baseline in a combined analysis of all subjects in the two groups. In conclusion, LP0132-fermented citrus
juice appears to have positive effects on some JCPsis symptoms and QOL in a population consuming immunomodulating probiotics such as LcS-fermented milk.

Efficacy of Polydextrose Supplementation on Colonic Transit Time, Bowel Movements, and Gastrointestinal Symptoms in Adults: A Double-Blind, Randomized, Placebo-Controlled Trial. Nutrients 2019; 11:nu11020439. [PMID: 30791557 PMCID: PMC6412485 DOI: 10.3390/nu11020439] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 02/08/2019] [Accepted: 02/15/2019] [Indexed: 12/17/2022] Open
Abstract
The addition of fiber is one of the most important dietary means to relieve constipation through lifestyle modification. Polydextrose (PDX) has been reported in several studies to increase fecal bulk, soften stools, and increase the number of defecations. However, there are few studies on the effect of PDX on colonic transit time (CTT). Therefore, the aim of this study was to demonstrate the effect of PDX on CTT and other aspects of gastrointestinal function during two weeks (Day 1 to Day 14), preceded by a 2-week run-in period (Day -14 to Day -1). A total of 192 adults who were diagnosed with functional constipation per Rome III criteria were recruited for the study. Participants were randomized equally into 4 groups (12 g, 8 g, or 4 g of PDX or placebo per day). The primary endpoint was CTT, assessed using radio-opaque markers and abdominal X-rays on Day 0, the baseline; and Day 15, the end of the intervention. Secondary outcomes that were measured using inventories were the patient assessment of constipation symptoms and quality of life, bowel function index, relief of constipation, bowel movement frequency (BMF), stool consistency, degree of straining, and proportion of bowel movements. Ancillary parameters and harms were also evaluated. The recruited population was not sufficiently constipated (e.g., baseline values for CTT and BMF of 42 h and 8.7 BMF/week, respectively). Despite this limitation, our results demonstrated an increased number of bowel movements when supplemented with PDX at a dosage of 12 g per day for 2 weeks. This dosage also consistently improved the secondary outcomes that were measured using inventories at Day 15, compared with the baseline. No serious or significant adverse events were reported during the study.

Abstract
BACKGROUND Although linaclotide has been approved to treat moderate to severe IBS-C, no data are available on its effectiveness and tolerability in patients in a real-life setting. METHODS A prospective single-center study of the effectiveness and tolerability of linaclotide was carried out on patients (n = 40) with moderate to severe IBS-C, all fulfilling the Rome IV criteria. Clinical information was recorded using a dietary questionnaire at baseline, and 3 and 6 months after initiating treatment. The end-points to measure effectiveness included abdominal pain and bloating (11-NRS), the number of bowel movements and patient satisfaction. Tolerability was assessed through the frequency of adverse events. KEY RESULTS In terms of efficacy, an improvement in abdominal pain and in the intensity of bloating was evident in the cohort after 6 months of linaclotide therapy. The proportion of patients with moderate or severe symptoms of bloating fell from 93.3% to 33.3% and those with pain from 93.4% to 20%. Weekly bowel movements also improved and accordingly, 97% of the patients were moderately or very satisfied with the treatment. At the end of the study, diarrhea was the most frequent adverse event (10%), although it was considered mild in 66.7% of these subjects and moderate in 33.3%. A lack of efficacy (n = 3) and excessive diarrhea (n = 7) were motives for discontinuing the treatment. CONCLUSIONS AND INFERENCES Linaclotide proved to be a safe and effective drug to reduce the main symptoms of IBS-C in everyday clinical practice, with an improvement comparable to that seen in clinical trials.

Abstract
BACKGROUND Recent studies have highlighted the relationship between gut microbiota and bowel movements. OBJECTIVE We aimed to evaluate transglucosidase treatment efficacy for bowel movements in patients with type 2 diabetes mellitus and to clarify the relationship between bowel movements, dietary habits, gut microbiota and fecal short-chain fatty acids. METHODS In this randomized double-blind, placebo-controlled study, 66 patients received placebo or transglucosidase (300 or 900 mg/day) orally, for 12 weeks. Fecal bacterial communities and short-chain fatty acids were analyzed before and after the treatment. RESULTS Transglucosidase treatment significantly (p < 0.05) affected fecal microbiota (Prevotella spp., Bacteroides spp., Bifidobacterium spp., and Clostridium subcluster XIVa) and fecal short-chain fatty acid (acetate, valerate, succinate and lactate) content. Clostridium cluster IV, Clostridium subcluster XIVa, Clostridium cluster XVIII and fecal pH increased significantly and order Lactobacillales decreased in patients with bowel movement disorder compared with controls. Transglucosidase treatment significantly improved bowel movements compared with placebo treatment (46.2%, 95% confidence interval: 19.2-74.9% vs. 0%, 95% confidence interval: 0-33.6%, p < 0.05). This effect was not observed in patients without bowel movement disorder. CONCLUSION Patients with bowel movement disorder suffer from gut dysbiosis. Transglucosidase treatment alleviates bowel movement disorder symptoms in type 2 diabetes mellitus patients by increasing fecal acetate level.

Abstract
A gradual loss of dopamine-producing nerve cells gives rise to a common neurodegenerative Parkinson’s disease (PD). This disease causes a neurotransmitter imbalance in the brain and initiates a cascade of complications in the rest of the body that appears as distressing symptoms which include gait problems, tremor, gastrointestinal (GI) disorders and cognitive decline. To aid dopamine deficiency, treatment in PD patients includes oral medications, in addition to other methods such as deep brain stimulation and surgical lesioning. Scientists are extensively studying molecular and signaling mechanisms, particularly those involving phenotypic transcription factors and their co-regulatory proteins that are associated with neuronal stem cell (SC) fate determination, maintenance and disease state, and their role in the pathogenesis of PD. Advancement in scientific research and “personalized medicine” to augment current therapeutic intervention and minimize the side effects of chemotherapy may lead to the development of more effective therapeutic strategies in the near future. This review focuses on PD and associated GI complications and summarizes the current therapeutic modalities that include stem cell studies and combinatorial drug treatment.

Abstract
Ulcerative colitis diagnosis and management represent a challenge for clinicians. The disguises of ischemia and acute infectious colitis continue to confound the diagnosis. The therapeutic options have remarkably expanded in the way of immunomodulators, biologics, or ileoanal pouch surgery, yet all carry potential considerable risks. These risks can confuse and impair patient acceptance, particularly elderly patients and men younger than 30 years. Predictors of outcome of medical and surgical therapy have improved but are far from complete. Nevertheless, therapies focused on the specific patient's condition continue to offer hope.

Abstract
Introduction: Chronic constipation is a common condition that is difficult to treat. Existing options for the treatment of patients with different subgroups of constipation are limited. A new efficacious and safe drug is needed to limit the frequently observed adverse effects induced by laxatives, to improve general wellbeing and quality of life, and to provide an alternative for enemas or even resectional surgery in patients in whom stimulant laxatives cause disabling adverse effects or fail to increase bowel movement frequency. Aims: The purpose of this article is to assess the current evidence supporting the use of the selective and high affinity serotonin-4 (5-HT4) receptor agonist prucalopride in the management of chronic constipation. Evidence review: There are now convincing data from phase II and multicenter phase III randomized, double-blind, placebo-controlled trials that prucalopride treatment results in a clinically meaningful increase in the number of spontaneous complete bowel movements, a reduction of perceived severity of symptoms and improved disease-related quality of life in a significant proportion of patients. There is a rapid onset of the effect and the improvement is maintained for at least 12 weeks. Prucalopride in a dose of up to 4 mg per day appeared generally well tolerated and devoid of serious cardiac events. Adverse events, most frequently headache and nausea, are usually mild or moderate and occur mainly during the first days of treatment. Prucalopride should be used with prudence and with careful assessment of the benefit-risk ratio until more clinical and electrophysiologic data become available, because relatively few patients have been exposed to the drug for long periods of time. Place in therapy: Prucalopride 1–2 mg once daily may be given to patients suffering from chronic constipation for whom laxatives do not provide adequate relief of their symptoms. Patients with severe constipation and slow transit, who frequently develop tolerance to stimulant laxatives, are also eligible for prucalopride treatment.

Abstract
This study examined the relation between bowel-related symptoms and self-report of constipation in 10,875 subjects aged 60 years and over, who participated in the 1989 National Health Interview Survey. Subjects reporting constipation "always" or "mostly" over the past 12 months (n = 594) were compared with those who reported never having the symptom (n = 4,192). Straining (adjusted odds ratio 66.7; 95% confidence interval 31.5, 142.4) and hard bowel movements (25.6; 16.7, 38.7) were most strongly associated with self-report of constipation. These findings suggest that treatment for constipation in the older population should be directed as much or more at facilitating comfortable rectal evacuation, as increasing bowel movement frequency.
