Effects of Cognitive Behavior Therapy on Heart Rate Variability in Young Females with Constipation-predominant Irritable Bowel Syndrome: A Parallel-group Trial.

ABSTRACT: The relation between heart rate variability (HRV) as non-invasive biomarkers of autonomic function and cognitive behavior therapy (CBT) as non-pharmacological treatments has rarely been examined in patients with constipation-predominant irritable bowel syndrome (IBS-C). The purpose of this study is to evaluate the efficacy of an 8-week CBT intervention on HRV and IBS symptoms, and the correlation of changes in HRV with changes in IBS symptoms among young female nursing students with IBS-C.This study consisted of an exploratory subgroup analysis of 43 participants with IBS-C who had been randomly assigned to receive either 8 weeks of CBT (n = 23) or general medical information (control, n = 20). At baseline and 8, 16, and 24 weeks, participants completed a questionnaire assessing their gastrointestinal (GI) symptoms, anxiety, depression, and stress, and their HRV was measured via electrocardiography.At the 8-week follow-up, the high-frequency (HF) power was significantly higher, and the low-frequency (LF)/HF ratio was lower in the CBT group than in the control group (P < 0.001 for both), and the severity of GI symptoms (P = 0.003), anxiety (P < 0.001), depression (P < 0.001), and stress (P < 0.001) was significantly lower in the CBT group than in the control group. Changes in the HF power were significantly and inversely associated with changes in GI symptoms, anxiety, depression, and stress at 16 and 24 weeks (P < 0.05 for all; range of r from -0.37 to -0.68). Changes in the LF/HF ratio were also significantly and positively associated with changes in GI symptoms, anxiety, depression, and stress at 16 and 24 weeks (P < 0.05 for all; range of r from 0.38 to 0.60).CBT was effective in managing symptoms in young IBS-C patients and the improvement of symptoms was sustained at 24 weeks following the completion of CBT. Furthermore, indirect measurement of autonomic function using HRV may be a useful objective parameter for assessing response to CBT in young IBS-C patients.

Project description:In this study, we aim to evaluate the efficacy and safety of acupoint catgut embedding for the treatment of diarrhea-predominant irritable bowel syndrome and constipation-predominant irritable bowel syndrome. We searched seven online databases to collect studies published up to Feb 29th, 2020. Study quality of each included article was evaluated by the Cochrane Collaboration Risk of Bias Tool. Systematic reviews and meta-analyses were conducted based on the Cochrane systematic review method by using RevMan 5.3 software. Among the included trials, acupoint catgut embedding alone or plus oral western medicine or plus other acupoint-based therapies, or plus oral traditional Chinese medicine were the main therapies in the experimental groups. Interventions in control groups mainly include oral western medicine alone, other acupoint-based therapies alone, or other acupoint-based therapies alone. Primary outcomes in this study include recovery rate, accumulative marked effective rate, accumulative effective rate, and recurrence rate. Finally, 30 trials involving 1889 participants were included. The results of systematic reviews and meta-analyses show that acupoint catgut embedding alone or plus oral western medicine or plus other acupoint-based therapy or plus oral traditional Chinese medicine was significantly better compared with using oral western medicine alone in terms of efficacy for IBS-C and IBS-D. In addition, acupoint catgut embedding alone or plus oral western medicine or plus other acupoint-based therapy or plus oral traditional Chinese medicine could improve the effective rate and decrease the recurrence rate for IBS-D compared with using oral western medicine, other acupoint-based therapies, or oral traditional Chinese medicine alone. Adverse events of acupoint catgut embedding include local induration, redness, swelling, and itchiness, but they were all mild and disappeared swiftly with ordinary local interventions. There is an urgent need for RCTs of high quality and large sample size and with longer treatment duration and follow-up periods of acupoint catgut embedding for IBS.

Project description:Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by chronic or recurrent abdominal pain in association with defecation or a change in bowel habits. A predominant disorder of bowel habits, IBS is classified into three main subtypes: constipation-predominant IBS (IBS-C), diarrhea-predominant IBS (IBS-D) and IBS alternating between constipation and diarrhea (IBS-M). Linaclotide is a first-in-class, oral, once-daily guanylate cyclase-C receptor agonist (GC-CA) that is licensed for the symptomatic treatment of moderate-to-severe IBS-C in adults. This review aims to facilitate and optimize clinical practices, establishing common guidelines to monitor patients with IBS-C that are treated with linaclotide.A group of experts in functional digestive disorders was convened to review the efficacy and safety of linaclotide and to develop an updated consensus report for the treatment of patients with IBS-C. A search was performed for English, French and Spanish language articles in PubMed. On the basis of the articles identified, an initial document was drafted addressing different issues frequently raised by general practitioners and GI specialists that are related to the prescription, efficacy and safety of linaclotide. This document was then reviewed and modified by the expert panel until a final text was agreed upon and validated.Based on the evidence, the panel addressed the following recommendations: (1) Linaclotide is indicated for the treatment of moderate to severe IBS-C in adults; (2) it is recommended that patients take linaclotide continuously and not sporadically; (3) patients should be warned about the risk of diarrhea and given choices concerning how to deal with this possible side effect; (4) the absence of tachyphylaxis or potential risks implies that linaclotide treatment can be maintained for long periods of time.This document seeks to lay down a set of recommendations and to identify key issues that may be useful for the clinical management of IBS-C patients treated with linaclotide.

Project description:BackgroundConstipation-predominant irritable bowel syndrome (IBS-C) mainly affects females, and dietary interventions for symptom relief often yield poor results because of low patient adherence. The development of functional food products enriched with dietary fibers may increase patients' adherence to a healthy diet and relieve IBS-С symptoms.ObjectiveThis proof-of-concept, open-label, randomized controlled pilot study is aimed to evaluate the efficacy of kombucha enriched with inulin and vitamins in females with IBS-C.MethodsForty females with IBS-C were randomly assigned to receive either 220 mL of kombucha enriched with inulin (2.53 g/220 mL) and vitamins (B1 - 0.59 mg, B2 - 0.55 mg, B3 - 5.9 mg, B6 - 0.7 mg, and folic acid - 81.4 μg/220 mL) or water for 10 d. Stool frequency, Bristol stool scale score (BSSS), and abdominal symptoms were evaluated using a 5-point Likert scale on days 5, 9 and 14 of the study. The palatability of the drink was assessed using a visual analog scale.ResultsAfter 10 d, the kombucha group showed a significant increase in stool frequency (0.60 ± 0.31-0.85 ± 0.19 times/d; P = 0.004) compared with the control (0.63 ± 0.33 compared with 0.72 ± 0.28; P = 0.6). The mean values of the BSSS increased in the kombucha group (3.0 ± 1.2-4.4 ± 1.0; P = 0.001), whereas they remained unchanged in the control (2.9 ± 1.2 compared with 3.4 ± 1.2; P = 0.6). The kombucha group also experienced a significant decrease in the feeling of incomplete bowel emptying (1.88 ± 0.78 compared with 1.41 ± 0.56 points; P = 0.015), which was not observed in the control group.ConclusionsShort-term consumption of kombucha enriched with inulin and vitamins was associated with an increase in stool frequency, an improvement in the BSSS, and a reduction in the feeling of incomplete bowel emptying in females with IBS-C. Further large-scale clinical trials investigating the efficacy of kombucha enriched with inulin and vitamins in patients with IBS-C are warranted to prove the observed effects.Trial registration numberThis trial was registered at clinicaltrials.gov as NCT05164861 (==https://clinicaltrials.gov/study/NCT05164861?term=NCT05164861&rank=1; registered on 18 December, 2021).
