Irritable bowel syndrome

Gregory Plotnikoff, Melissa Barber
INTRODUCTION: Single-disorder or single-organ-system clinical practice guidelines are often of limited usefulness in guiding effective management of patients with chronic multidimensional signs and symptoms. The presence of multiple long-standing medical problems in a given patient despite intensive medical effort suggests that addressing systemic core imbalances could complement more narrowly focused approaches. CASE PRESENTATION: A 72-year-old man experiencing longstanding depression, fatigue, irritable bowel syndrome, and chronic pain in the context of additional refractory illnesses was assessed and treated, guided by a system-oriented approach to underlying core imbalances termed functional medicine...

Serotonin type 3 (5-HT3 ) receptors are ligand-gated ion channels formed by five subunits (5-HT3 A-E), which are encoded by the HTR3A, HTR3B, HTR3C, HTR3D and HTR3E genes. Functional receptors are pentameric complexes of diverse composition. Different receptor subtypes confer a predisposition to nausea and vomiting during chemotherapy, pregnancy, and following surgery. In addition, different subtypes contribute to neurogastroenterologic disorders such irritable bowel syndrome (IBS) and eating disorders as well as comorbid psychiatric conditions...

The gastrointestinal tract consists of an enormous surface area that is optimized to efficiently absorb nutrients, water, and electrolytes from food. At the same time, it needs to provide a tight barrier against the ingress of harmful substances, and protect against a reaction to omnipresent harmless compounds. A dysfunctional intestinal barrier is associated with various diseases and disorders. In this review, the role of intestinal permeability in common disorders such as infections with intestinal pathogens, inflammatory bowel disease, irritable bowel syndrome, obesity, celiac disease, non-celiac gluten sensitivity, and food allergies will be discussed...

Irritable bowel syndrome (IBS) is the most common cause of non-organic recurrent abdominal pain in children. IBS is a clinical diagnosis, which is based on the Rome IV criteria for functional gastrointestinal disorders in children, as well as the patient's history. The diagnosis of IBS is established following the exclusion of organic causes of recurrent abdominal pain. Staggered investigations should be avoided because they might increase the child's and family's anxiety in the absence of an organic diagnosis...

BACKGROUND: Irritable bowel syndrome (IBS) costs the National Health Service almost £12 million per annum. Despite national guidelines advising primary care management, these have failed to stem secondary care referrals of patients with likely IBS for unnecessary and costly assessment and investigation without necessarily achieving resolution of their symptoms. METHODS: In 2011, an integrated team from primary and secondary care developed a business case using baseline data to create a Somerset-wide IBS pathway using Clinical Commissioning Group funding...

Irritable Bowel Syndrome (IBS) is a chronic digestive disorder, which is characterized by abdominal pain, bloating, diarrhea and constipation periods. The etiology is unknown. Based on the different mechanisms in the etiology, treatment focuses on controlling symptoms. Due to the longtime of syndrome, inadequacy of current treatments, financial burden for patients and pharmacologic effects, several patients have turned to the use of complementary and alternative medicine (CAM). Complementary and alternative treatments for IBS include hypnosis, acupuncture, cognitive behavior therapy, yoga, and herbal medicine...

Major depressive disorder (MDD) and irritable bowel syndrome (IBS) frequently co-occur, yet treating their comorbid presentation is challenging. Low-dose tricyclic antidepressants are efficacious for IBS, but higher doses to treat depressive symptoms present tolerability problems, whereas selective serotonin reuptake inhibitors are more tolerable but show inconsistent efficacy for IBS. If efficacious, serotonin-norepinephrine reuptake inhibitors like duloxetine would provide a useful alternative. We explored efficacy, tolerability, and time to onset of action of duloxetine in comorbid IBS-MDD in an open-label, 12-week trial...

OBJECTIVES: Celiac disease (CD) and irritable bowel syndrome (IBS) share similar symptoms, leading to confusion between the two and diagnostic delay. International guidelines recommend screening individuals with IBS for CD, via serological testing. However, studies published recently have cast doubt on the utility of this. We updated a previous meta-analysis examining this issue. METHODS: MEDLINE, EMBASE, and EMBASE Classic were searched through to May 2016. Eligible studies recruited adults with IBS according to symptom-based criteria, physician's opinion, or questionnaire data...

Elevated basal serum tryptase levels are present in 4-6% of the general population, but the cause and relevance of such increases are unknown. Previously, we described subjects with dominantly inherited elevated basal serum tryptase levels associated with multisystem complaints including cutaneous flushing and pruritus, dysautonomia, functional gastrointestinal symptoms, chronic pain, and connective tissue abnormalities, including joint hypermobility. Here we report the identification of germline duplications and triplications in the TPSAB1 gene encoding α-tryptase that segregate with inherited increases in basal serum tryptase levels in 35 families presenting with associated multisystem complaints...
