Review
Chronic abdominal and pelvic pain are common debilitating clinical conditions experienced by millions of patients around the globe. The origin of such pain commonly arises from the intestine and bladder, which share common primary roles (the collection, storage, and expulsion of waste). These visceral organs are located in close proximity to one another and also share common innervation from spinal afferent pathways. Chronic abdominal pain, constipation, or diarrhea are primary symptoms for patients with irritable bowel syndrome or inflammatory bowel disease. Chronic pelvic pain and urinary urgency and frequency are primary symptoms experienced by patients with lower urinary tract disorders such as interstitial cystitis/painful bladder syndrome. It is becoming clear that these symptoms and clinical entities do not occur in isolation, with considerable overlap in symptom profiles across patient cohorts. Here we review recent clinical and experimental evidence documenting the existence of "cross-organ sensitization" between the colon and bladder. In such circumstances, colonic inflammation may result in profound changes to the sensory pathways innervating the bladder, resulting in severe bladder dysfunction.

BACKGROUND
Little information is available in spinocerebellar ataxias (SCAs) regarding pelvic organ symptoms. The aim of this study was to characterize the lower urinary tract (LUT) and bowel dysfunction in autosomal dominant spinocerebellar ataxias.
METHODS
Patients with confirmed SCAs attending a tertiary care service were approached about LUT and bowel complaints, and completed validated questionnaires: urinary symptom profile (USP), Qualiveen-Short form, International Prostate Symptom Score, and Neurogenic Bowel Dysfunction Score. SCA3 and SCA7 patients with urological complaints additionally underwent urodynamic studies (UDS). Patients' characterization included demographic, clinical (Scale for the Assessment and Rating of Ataxia (SARA), Inventory of Non-Ataxia Signs (INAS)), and genetic variables. Descriptive and comparative analyses were performed.
RESULTS
Fifty-one patients participated: SCA1 (n = 4), SCA2 (n = 11), SCA3 (n = 13), SCA6 (n = 17), and SCA7 (n = 6). The prevalence of self-reported LUT symptoms was 60.8% (n = 31), whereas LUT symptoms was reported in 86.3%(n = 44) using the USP. Both storage and voiding symptoms were reported, urinary frequency and urgency being the most frequent (n = 34, 68%). Although LUT symptoms were most often classed as mild (n = 27, 61.4%), they impacted QoL in 38 patients (77.6%). Of these, 21 (55.3%) were not on pharmacological treatment for urinary dysfunction. Most common abnormalities in UDS (n = 14) were detrusor overactivity (storage phase) and detrusor underactivity (voiding phase). Bowel symptoms were less common (31.4%, n = 16) and of mild severity.
CONCLUSION
LUT symptoms are prevalent in SCA patients and impact QoL, whereas bowel symptoms tend to be mild. These symptoms are overlooked by patients and physicians due to the complexity of neurological involvement in SCA, and therefore a multidisciplinary management approach should be adopted.

Randomized Controlled Trial
PURPOSE
Rifaximin is indicated for the treatment of irritable bowel syndrome with diarrhea (IBS-D) in adults. The current aim was to evaluate rifaximin efficacy on individual and composite IBS-D symptoms using definitions not previously examined.
METHODS
Phase III post hoc analyses of two randomized, double-blind, placebo-controlled trials and the open-label phase of a randomized, double-blind, placebo-controlled trial were conducted. Adults with IBS-D received a 2-week course of rifaximin 550 mg TID. Individual and composite responses for abdominal pain (mean weekly improvements from baseline of ≥30%, ≥40%, or ≥50%), bloating (mean weekly improvements from baseline of ≥1 or ≥2 points; or ≥30%, ≥40%, or ≥50%), stool consistency (mean weekly average stool consistency score <3 or <4), and urgency (improvement from baseline of ≥30% or ≥40% in percentage of days with urgency) for ≥2 of the first 4 weeks after treatment, and weekly for 12 weeks, were assessed.
FINDINGS
Overall, 1258 patients from the double-blind trials (rifaximin [n = 624]; placebo [n = 634]) and 2438 from an open-label trial were analyzed. The percentage of bloating or urgency responders was significantly greater with double-blind rifaximin versus placebo (P ≤ 0.03). A significantly greater percentage of the double-blind group were composite abdominal pain and bloating responders versus placebo for all thresholds analyzed (P < 0.05). A significantly greater percentage of the double-blind group were tri-symptom composite end point responders (abdominal pain, bloating, and fecal urgency) versus placebo (P = 0.001). A significantly greater percentage of patients achieved response (≥30% composite tri-symptom threshold) with double-blind rifaximin versus placebo as early as 1 week posttreatment, with significance maintained through ≥5 weeks after treatment. Open-label results were consistent with those of the double-blind study.
IMPLICATIONS
Rifaximin significantly improved multiple, concurrent IBS-D symptoms, using clinically relevant definitions of treatment response. Using a novel tri-symptom composite end point (ie, abdominal pain, bloating, fecal urgency), adults with IBS-D treated with a 2-week course of rifaximin were significantly more likely to be composite end point responders than those receiving placebo (≥30% or ≥40% threshold) for the three symptoms. Thus, rifaximin not only met current standard thresholds used for adjudication of responders in clinical trials but also achieved higher thresholds for many of these symptoms, suggesting potential for even more robust clinical improvements.

Review
Inflammatory bowel disease (IBD) is a group of chronic disorders, including Crohn's disease (CD) and ulcerative colitis (UC), that contribute to inflammation of the gastrointestinal tract, manifesting as bloody diarrhea, fecal urgency, bloating, cramping, and weight loss. IBD manifests as an exacerbation of these symptoms, which medications with high side effect profiles can manage; consequently, many novel therapies, including biologics such as ustekinumab and vedolizumab, have been developed over the years. This systematic review aims to assess the safety and efficacy of ustekinumab and vedolizumab in treating inflammatory bowel disease based on a comprehensive analysis of relevant studies. A thorough literature search was conducted to identify randomized controlled trials, post hoc analyses, case reports, observational cohorts, and meta-analyses involving ustekinumab and vedolizumab as treatment in IBD patients. The selected studies were critically evaluated for their methodology, patient characteristics, and outcomes. The analysis involved twelve distinct studies investigating the impact of ustekinumab and vedolizumab on individuals afflicted with inflammatory bowel disease (IBD). The findings revealed a notable trend: ustekinumab displayed a propensity for yielding higher rates of clinical remission in patients with ulcerative colitis (UC). Moreover, one study underscored substantial reductions in endoscopic disease activity in patients with Crohn's disease (CD) who were on ustekinumab. Similarly, ustekinumab exhibited promising outcomes in CD patients, including swift ultrasound responses and the achievement of transmural remission, particularly among those who were new to biologic treatments. In line with this, vedolizumab demonstrated early and considerable symptomatic improvements when used to treat both UC and CD patients. While both biologics showed promising results in inducing and maintaining remission, cautious monitoring is warranted due to the potential adverse events observed in some cases. Further research with larger sample sizes and longer follow-up periods is needed to establish a comprehensive understanding of the medications' effects on IBD patients.

Bile acid diarrhea (BAD) is characterized by increased frequency of bowel movements, looser stool consistency, urgency, and need for proximity to toilet facilities owing to the severity of the diarrhea, when compared with or relative to irritable bowel syndrome with diarrhea. Consequently, BAD leads to decreased quality of life. The condition is often misdiagnosed as irritable bowel syndrome with diarrhea or functional diarrhea. Patients with BAD have accelerated colonic transit, increased intestinal or colonic mucosal permeability, and altered stool microbiome composition associated with reduced dehydroxylation of primary to secondary bile acids. The established diagnostic test, selenium-75 homocholic acid taurine retention, is not available in the United States. Therefore, 48-hour fecal bile acid excretion has been the gold standard for diagnosis. With recent validation of combined measurement of primary bile acids in a single, random stool in addition to fasting serum 7α-hydroxy-4-cholesten-3-one, a practical point-of-care diagnostic test will soon be available. Randomized controlled trials have documented superiority of colesevelam to placebo and, in a separate study, superiority of the glucagon-like peptide 1 agonist liraglutide compared with colesevelam. Novel experimental approaches for BAD include farnesoid X receptor agonists and fibroblast growth factor 19 analogs. This article updates information on the pathophysiology, mechanisms, manifestations, diagnosis, and treatment of BAD.

Review
Inflammatory bowel disease is a chronic intestinal inflammatory condition, the pathology of which is incompletely understood. Gut inflammation causes significant changes in neurally controlled gut functions including cramping, abdominal pain, fecal urgency, and explosive diarrhea. These symptoms are caused, at least in part, by prolonged hyperexcitability of enteric neurons that can occur following the resolution of colitis. Mast, enterochromaffin and other immune cells are increased in the colonic mucosa in inflammatory bowel disease and signal the presence of inflammation to the enteric nervous system. Inflammatory mediators include 5-hydroxytryptamine and cytokines, as well as reactive oxygen species and the production of oxidative stress. This review will discuss the effects of inflammation on enteric neural activity and potential therapeutic strategies that target neuroinflammation in the enteric nervous system.

Review
Restorative proctocolectomy with ileal-pouch anal anastomosis (IPAA) is the operation of choice for medically refractory ulcerative colitis (UC), for UC with dysplasia, and for familial adenomatous polyposis (FAP). IPAA can be a treatment option for selected patients with Crohn's colitis without perianal and/or small bowel disease. The term "pouchitis" refers to nonspecific inflammation of the pouch and is a common complication in patients with IPAA; it occurs more often in UC patients than in FAP patients. This suggests that the pathogenetic background of UC may contribute significantly to the development of pouchitis. The symptoms of pouchitis are many, and can include increased bowel frequency, urgency, tenesmus, incontinence, nocturnal seepage, rectal bleeding, abdominal cramps, and pelvic discomfort. The diagnosis of pouchitis is based on the presence of symptoms together with endoscopic and histological evidence of inflammation of the pouch. However, "pouchitis" is a general term representing a wide spectrum of diseases and conditions, which can emerge in the pouch. Based on the etiology we can sub-divide pouchitis into 2 groups: idiopathic and secondary. In idiopathic pouchitis the etiology and pathogenesis are still unclear, while in secondary pouchitis there is an association with a specific causative or pathogenetic factor. Secondary pouchitis can occur in up to 30% of cases and can be classified as infectious, ischemic, non-steroidal anti-inflammatory drugs-induced, collagenous, autoimmune-associated, or Crohn's disease. Sometimes, cuffitis or irritable pouch syndrome can be misdiagnosed as pouchitis. Furthermore, idiopathic pouchitis itself can be sub-classified into types based on the clinical pattern, presentation, and responsiveness to antibiotic treatment. Treatment differs among the various forms of pouchitis. Therefore, it is important to establish the correct diagnosis in order to select the appropriate treatment and further management. In this editorial, we present the spectrum of pouchitis and the specific features related to the diagnosis and treatment of the various forms.

Alimentary Pharmacology & Therapeutics Nov 2021Microscopic colitis is an increasingly common cause of watery diarrhoea. Several classes of medications have been associated with microscopic colitis in prior studies.
BACKGROUND
Microscopic colitis is an increasingly common cause of watery diarrhoea. Several classes of medications have been associated with microscopic colitis in prior studies.
AIMS
To determine the association between the use of previously implicated medications and microscopic colitis.
METHODS
This was a case-control study of patients referred for elective, outpatient colonoscopy for diarrhoea. Patients were excluded for inflammatory bowel disease, C difficile, or other infectious diarrhoea. Colon biopsies were reviewed by the study pathologist and patients were classified as microscopic colitis cases or non-microscopic colitis controls.
RESULTS
The study population included 110 microscopic colitis cases and 252 controls. The cases were older, better educated and more likely to be female. Cases reported a greater number of loose, watery, or liquid stools, nocturnal stools, more urgency and weight loss compared to controls. There was no association with proton pump inhibitors (PPIs), adjusted OR (aOR) 0.66, 95% CI 0.38-1.13 or nonsteroidal anti-inflammatory drugs, aOR 0.68, 95% CI 0.40-1.17. Cholecystectomy was less common in cases, aOR 0.33, 95% CI 0.17-0.64, but microscopic colitis cases had more frequent bowel movements following cholecystectomy.
CONCLUSION
Compared to similar patients with diarrhoea, cases with microscopic colitis were not more likely to have taken previously implicated medications. They had more diarrhoea following cholecystectomy, suggesting that bile may play a role in symptoms or aetiology. We conclude that the appropriate choice of controls is crucial to understanding risk factors for microscopic colitis.

Upadacitinib Treatment Improves Symptoms of Bowel Urgency and Abdominal Pain, and Correlates With Quality of Life Improvements in Patients With Moderate to Severe Ulcerative Colitis.
BACKGROUND AND AIMS
Bowel urgency and abdominal pain are impactful, yet under-appreciated ulcerative colitis symptoms and not commonly assessed in clinical trials. We evaluated how these symptoms may improve with upadacitinib treatment and correlate with clinical and health-related quality of life [HRQOL] outcomes in the phase 2b U-ACHIEVE study.
METHODS
Patients aged 18-75 years, with moderately to severely active ulcerative colitis, were randomised to receive placebo or upadacitinib (7.5, 15, 30, or 45 mg once daily [QD]). Bowel urgency and abdominal pain were evaluated at baseline and Weeks 2, 4, 6, and 8. Week 8 correlations were evaluated between bowel urgency/abdominal pain with clinical [Mayo subscores and high-sensitivity C-reactive protein and faecal calprotectin measurements] and HRQOL outcomes [Inflammatory Bowel Disease Questionnaire and 36-Item Short Form Health Survey scores].
RESULTS
A greater proportion of patients [n = 250] reported no bowel urgency and less abdominal pain with upadacitinib treatment compared with placebo, with improvements observed as early as 2 weeks. At Week 8, patients receiving the 45-mg QD dose had the greatest improvements versus placebo, with 46% reporting no bowel urgency [vs 9%; p ≤ 0.001] and 38% reporting no abdominal pain [vs 13%; p = 0.015]. At Week 8, moderate correlations were found between bowel urgency or abdominal pain and most clinical and HRQOL outcomes.
CONCLUSIONS
Induction treatment with upadacitinib demonstrated significant reductions in bowel urgency and abdominal pain compared with placebo. These symptoms also correlate to clinical and HRQOL outcomes, supporting their use to monitor disease severity and other treatment outcomes.

OBJECTIVE
To estimate the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms experienced by children with osteogenesis imperfecta and to describe the socio-demographic and clinical profile of these children.
METHOD
A descriptive study was conducted with a convenience sample of parent-child pairs of toilet-trained children aged from 3 to 18 years. Pairs were interviewed using three tools: (1) Socio-Demographic and Clinical Questionnaire; (2) Dysfunctional Voiding Scoring System; (3) Rome III Criteria along with the Bristol Stool Scale. Data were stratified by socio-demographic and clinical variables and analyzed using descriptive statistics.
RESULTS
Thirty-one parent-child pairs participated in the study; 38.7% (n=12) children reported bowel symptoms, 19.4% (n=6) reported a combination of bladder issues (such as holding maneuvers and urgency) and bowel symptoms (such as hard or painful bowel movements and large diameter stools). There were no reports of isolated bladder issues. Among the child participants, 16 (51.7%) identified as female and 20 (64.5%) were 5-14 years old. The most prevalent type of osteogenesis imperfecta was type III (n=12; 38.7%) and eight (25.8%) children reported using a wheelchair.
CONCLUSION
This is the first study to examine the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms in children with osteogenesis imperfecta, offering a preliminary socio-demographic and clinical profile of these children. This research is an important step toward effective screening, detection, and access to care and treatment, especially for clinicians working with this group of very fragile patients.
