Objective: To screen for differentially expressed serum microRNAs (miRNAs) in patients with diarrhea-predominant irritable bowel syndrome (IBS-D) compared with healthy participants and explore the mechanism of acupuncture in the treatment of IBS-D based on miRNAs. Methods: IBS-D patients that met the Rome III diagnostic criteria and age- and sex-matched healthy participants were enrolled between April 2017 and December 2017. Serum miRNA levels were initially determined using a TaqMan low-density array (TLDA) in pooled samples. Markedly altered miRNAs in IBS-D patients were subsequently validated using quantitative real-time polymerase chain reaction (qRT-PCR) on individual samples. All IBS-D patients accepted the acupuncture therapy for 6 weeks. The disease severity was assessed using the IBS symptom severity scale (IBS-SSS) questionnaire before and after treatment. After acupuncture, the patients’ serum was re-analyzed for altered expression of the miRNAs by qRT-PCR. Results: TLDA and qRT-PCR analysis revealed six upregulated miRNAs (miR-1305, miR-575, miR-149-5p, miR-190a-5p, miR-135a-5p, and miR-148a-3p; P < 0.05) and two downregulated miRNAs (miR-194-5p, miR-127-5p; P < 0.05) in IBS-D patients compared with healthy controls. Post acupuncture treatment, total IBS-SSS scores, severity of abdominal pain, duration of abdominal pain, severity of abdominal distention, dissatisfaction with bowel habits and disruption in quality of life decreased significantly ( P < 0.001). Furthermore, the upregulated miR-148a-3p levels in IBS-D patients also decreased significantly after acupuncture ( P < 0.05). Conclusions: The over-expression or reduced expression of several miRNAs may contribute to IBS-D pathogenesis. Acupuncture might downregulate miR-148a-3p through multiple pathways to alleviate or relieve IBS-D symptoms. Trial registration number: ChiCTR-IOR-17010860 (Chinese Clinical Trials Registry)

Objectives. The purpose of this study was to investigate whether the ingestion of alkaline-reduced water (ARW) is helpful in improving the symptoms of diarrhea-predominant irritable bowel syndrome (IBS). Methods. Twenty-seven patients (male, 25.9%; mean, 41.7 years old) with diarrhea-predominant IBS were randomly allocated to two groups. For eight weeks, the ARW group (n=13) ingested at least 2 liters/day of ARW, while the control group (n=14) ingested placebo water. IBS symptom scores (quality-of-life, abdominal pain/discomfort), stool form, and frequency were assessed before and after treatment via questionnaires. Results. Eight patients (61.5%) in the ARW group and six patients (42.9%) in the control group indicated that their symptoms had improved in more than four out of the eight weeks of treatment (p=0.449). The IBS quality-of-life score significantly improved from 57.2 to 30.8 in the ARW group; this improvement was significantly greater than the slight improvement from 48.7 to 42.2 observed in the control group (p=0.029). The abdominal pain score improved from 1.8 to 0.9 in the ARW group and from 1.8 to 1.1 in the control group, with no significant group difference (p=0.232). Conclusions. Drinking ARW for eight weeks improves the quality of life in patients with diarrhea-predominant IBS.

Abstract Background Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disease characterized by chronic abdominal discomfort and pain. The mechanisms of abdominal pain, as a relevant symptom, in IBS are still unclear. We aimed to explore the key genes and neurobiological changes specially involved in abdominal pain in IBS. Methods Gene expression data (GSE36701) was downloaded from Gene Expression Omnibus database. Fifty-three rectal mucosa samples from 27 irritable bowel syndrome with diarrhea (IBS-D) patients and 40 samples from 21 healthy volunteers as controls were included. Differentially expressed genes (DEGs) between two groups were identified using the GEO2R online tool. Functional enrichment analysis of DEGs was performed on the DAVID database. Then a protein–protein interaction network was constructed and visualized using STRING database and Cytoscape. Results The microarray analysis demonstrated a subset of genes (CCKBR, CCL13, ACPP, BDKRB2, GRPR, SLC1A2, NPFF, P2RX4, TRPA1, CCKBR, TLX2, MRGPRX3, PAX2, CXCR1) specially involved in pain transmission. Among these genes, we identified GRPR, NPFF and TRPA1 genes as potential biomarkers for irritating abdominal pain of IBS patients. Conclusions Overexpression of certain pain-related genes (GRPR, NPFF and TRPA1) may contribute to chronic visceral hypersensitivity, therefore be partly responsible for recurrent abdominal pain or discomfort in IBS patients. Several synapses modification and biological process of psychological distress may be risk factors of IBS.

Background and Aim: Irritable bowel syndrome (IBS) is a complex and heterogeneous disorder. Sensory, motor and barrier dysfunctions are the key physiological endophenotypes of IBS. Our aim is to review studies evaluating barrier dysfunction in adults and children with IBS, as well as to link those changes with IBS symptomatology and quality of life. Methods: A comprehensive and systematic review of multiple databases was performed up to March 2020 to identify studies comparing intestinal permeability in IBS patients with healthy controls. Both in vivo and in vitro studies were considered. Results: We identified 66 studies, of which 27 used intestinal probes to quantify barrier function. The prevalence of barrier dysfunction differed between PI-IBS (17–50%), IBS-D (37–62%) and IBS-C (4–25%). At a group level, permeability was increased compared with healthy controls in IBS-D (9/13 studies) and PI-IBS (4/4 studies), but only a minority of IBS-C (2/7 studies) and not in the only IBS-M study. All four studies in children with IBS demonstrated loss of barrier function. A heterogeneous set of tight junction genes were found to be altered in small and large intestines of adults with IBS, but these have not been evaluated in children. Positive associations were identified between barrier dysfunction and bowel disturbances (6/9 studies), abdominal pain (9/13 studies), overall symptom severity (1/6 studies), depression and anxiety (1/1 study) and quality of life (1/4 studies). Fecal slurry or supernatants of IBS patients were found to induce barrier disruption in animal models (5/6 studies). Conclusions: Barrier dysfunction is present in a significant proportion of adult and all pediatric IBS studies, especially in the IBS-D and PI-IBS subtype. The majority of studies indicated a positive association between loss of barrier function and symptoms such as abdominal pain and changes in the bowel function.

Irritable bowel syndrome (IBS) is characterized by recurrent abdominal pain or discomfort that has occurred at least 3 days per month in the 3 months prior to diagnosis. One of the subtypes of this disorder is IBS with constipation (IBS-C), where individuals experience hard or lumpy stools at least 25% of the time and loose or watery stools less than 25% of the time with defecation. This review addresses IBS-C, detailing the epidemiology, etiology, pathophysiology and pathogenesis, diagnosis, differential diagnosis, treatment, and prognosis. A figure shows the Bristol stool form scale. Tables list IBS subtypes, components of digital rectal examination, differential diagnoses for IBS and IBS-C, alarm features, and the American College of Gastroenterology Recommendations. This review contains 1 highly rendered figure, 6 tables, and 71 references.
