Pain treatments less effective for those with irritable bowel

(University of Adelaide) University of Adelaide researchers have discovered that the immune system is defective in people suffering from irritable bowel syndrome, which is a major reason why sufferers have ongoing issues with pain.

CONCLUSIONS: There is currently not enough evidence to assess whether biofeedback interventions are effective for controlling symptoms of IBS. Given the positive results reported in small trials to date, biofeedback deserves further study in people with IBS. Future research should include active control groups that use high provider-participant interaction, in an attempt to balance non-specific effects of interventions between groups, and report both commonly used outcome measures (e.g. IBS-SSS) and historical outcome measures (e.g. the composite primary symptom reduction (CPSR) score) to allow for meta-analysis with previ...

AbstractIrritable bowel syndrome (IBS) is a functional bowel disorder characterized by abdominal pain and alterations in stool form and/or frequency, leading to reduced quality of life. Pharmacologic agents currently approved by the US Food and Drug Administration for treatment of IBS with diarrhea (IBS-D) in adults are the nonsystemic antibiotic rifaximin, the mixed µ- and κ-opioid receptor agonist/δ-opioid antagonist eluxadoline, and the selective serotonin 5-HT3 antagonist alosetron (the last of which is indicated only in women with severe IBS-D refractory to conventional therapy). Both eluxadoline and...

ConclusionsLow or very low certainty evidence indicated that there was no difference between CGEC and WCM in the treatment of IBS-D. The combination of CGEC and WCM has a better therapeutic effect than WCM alone in the treatment of IBS-D. Future large sample, multi-center and high-quality RCTs should be rigorously designed and implemented to evaluate the clinical effects and safety of CGEC for IBS-D.

Irritable bowel syndrome (IBS) is characterized by abdominal pain, bloating, and erratic bowel habits. A diet low in fermentable oligo-, di-, mono-saccharides and polyols (FODMAPs) can reduce symptoms of IBS, possibly by reducing microbial fermentation products. We investigated whether ingestion of FODMAPs can induce IBS-like visceral hypersensitivity mediated by fermentation products of intestinal microbes in mice.

AbstractObjectiveTo observe the clinical efficacy of acupuncture treatment for depressive symptom in diarrhea-predominant irritable bowel syndrome (IBS-D).MethodsA total of 70 patients with IBS-D accompanied by depressive symptom were randomized into a control group and an observation group, with 35 cases in each group. The control group was treated with oral intake of pinaverium bromide tablets, and the observation group was treated with regulating liver and spleen acupuncture treatment. The two groups were treated for 4 weeks. The scores of IBS symptom severity scale (IBS-SSS) and self-rating depression scale (SDS) were ...

AbstractChildren with chronic idiopathic constipation (CIC) often end up at the surgeon when medical treatments have failed. This opinion piece discusses a recently described pattern of CIC called ‘Rapid transit constipation (RTC)’ first identified in 2011 as part of surgical workup. RTC was identified using a nuclear medicine gastrointestinal transit study (NMGIT or nuclear transit study) to determine the site of slowing within the bowel and to inform surgical treatment. Unexpectedly, we found that RTC occured in 29% of 1000 transit studies in a retrospective audit. Irritable bowel syndrome (IBS) occurs in 7&n...

In this study, chronic visceral pain animal model was established by injection with zymosan into the colon of adult male C57/BL6 mice. Whole cell patch ‐clamp recording, behavioral tests, Western blot, and Cannulation and ACC microinjection were employed to explore the role of adenylyl cyclase 1 (AC1) in the ACC of C57/BL6 and AC1 knock out (AC1 KO) mice. Integrative approaches were used to investigate possible changes of neuronal adenylyl cyclas e 1 (AC1) in the ACC after the injury. We found that AC1, a key enzyme for pain‐related cortical plasticity, was significantly increased in the ACC in an animal model of irrit...

CONCLUSIONS: Patients with Chronic Fatigue Syndrome should be evaluated for current psychiatric conditions because of their impact on patient quality of life, but they do not act as a symptom multiplier for the illness. Other co-existing medically unexplained syndromes are more common than psychiatric co-morbidities in patients presenting for evaluation of medically unexplained fatigue and are also more associated with increased disability and the number and severity of symptoms. Key Messages When physicians see patients with medically unexplained fatigue, they often infer that this illness is due to an underlying psychiat...

SeppenAbstractVisceral pain, characterized by abdominal discomfort, originates from organs in the abdominal cavity and is a characteristic symptom in patients suffering from irritable bowel syndrome, vulvodynia or interstitial cystitis. Most organs in which visceral pain originates are in contact with the external milieu and continuously exposed to microbes. In order to maintain homeostasis and prevent infections, the immune- and nervous sy...
