Abstract
Background Guidelines fail to recommend objective measures to assist with treatment of neurogenic bowel dysfunction (NBD) in spinal cord injury (SCI). Objectives The main objective was to review the literature to identify the objective measures used in all NBD populations and to present their results and any correlations performed to validated subjective measures. Methods A systematic review of the literature was performed in accordance with PRISMA (2020) guidelines, including all records from January 2012 to May 2023 with MeSH terms like "neurogenic bowel" indexed in the following databases: PubMed, EMBASE, CINAHL, Cochrane Central Trials Register, and ClinicalTrials.gov. Abstracts were excluded if they did not include objective measures or if they only mentioned the esophagus, stomach, and/or small bowel. Records were screened independently by at least two collaborators, and differences were resolved by unanimous agreement. Results There were 1290 records identified pertaining to NBD. After duplicates were removed, the remaining records were screened for a total of 49 records. Forty-one records (82%) included subjective measures. Two-thirds of the articles involved the population with SCI/disease (n = 552) and one-third were non-SCI NBD (n = 476). Objective measures were categorized as (1) transit time, (2) anorectal physiology testing, and (3) miscellaneous. Of the 38 articles presenting results, only 16 (42%) performed correlations of objective measures to subjective measures. Conclusion There is an abundance of literature supporting the use of objective outcome measures for NBD in SCI. Strong correlations of subjective measures to objective outcome measures were generally lacking, supporting the need to use both measures to help with NBD management.

Abstract
Gastrointestinal (GI) dysfunction is a common nonmotor symptom in Parkinson's disease (PD) as well as other parkinsonian syndromes and may precede the onset of motor symptoms by decades. Involvement of all segments of the GI tract can lead to altered responses to medications and worsened quality of life for patients. While some GI symptoms occur in isolation, others overlap. Therefore, understanding the changes in different segments of the GI tract and how they relate to altered responses to PD treatment can guide both diagnostic and pharmacological interventions. Gut microbiota plays a critical role in immune activity and modulation of the enteric and central nervous systems. Understanding this bidirectional relationship helps to elucidate the pathogenesis of neurodegeneration. This review will describe the current understanding of how GI dysfunction develops in parkinsonian syndromes, common symptoms in PD and related disorders, and available treatments.

Abstract
Lewy body diseases, such as Parkinson's disease and dementia with Lewy bodies, vary in their clinical phenotype but exhibit the same defining pathological feature, α-synuclein aggregation. Microbiome-gut-brain dysfunction may play a role in the initiation or progression of disease processes, though there are multiple potential mechanisms. We discuss the need to evaluate gastrointestinal mechanisms of pathogenesis across Lewy body diseases, as disease mechanisms likely span across diagnostic categories and a 'body first' clinical syndrome may better account for the heterogeneity of clinical presentations across the disorders. We discuss two primary hypotheses that suggest that either α-synuclein aggregation occurs in the gut and spreads in a prion-like fashion to the brain or systemic inflammatory processes driven by gastrointestinal dysfunction contribute to the pathophysiology of Lewy body diseases. Both of these hypotheses posit that dysbiosis and intestinal permeability are key mechanisms and potential treatment targets. Ultimately, this work can identify early interventions targeting initial disease pathogenic processes before the development of overt motor and cognitive symptoms.

Clinical Effect of Acupuncture Combined with Traditional Chinese Medicine Application on the Treatment of Functional Dyspepsia in Children and the Influence on Serum 5-HT and NO Levels. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:6800662. [PMID: 35401711 PMCID: PMC8989592 DOI: 10.1155/2022/6800662] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/15/2022] [Accepted: 03/21/2022] [Indexed: 12/29/2022]
Abstract
Objective To explore the clinical effect of acupuncture combined with traditional Chinese medicine (TCM) application on the treatment of functional dyspepsia (FD) in children and the influence on serum 5-HT and NO levels. Methods 94 FD children admitted to the pediatric department of our hospital from March 2019 to March 2020 were selected as the research object and divided into the study group (n = 45) and reference group (n = 49) by the number table method. The routine Western medicine therapy was given to the reference group and the combination therapy of acupuncture and TCM application was given to the study group to analyze the effect of different therapies on FD children by detecting their serum 5-hydroxytryptamine (5-HT) and nitric oxide (NO) levels and electrogastrogram (EGG) before and after treatment. Results The sex ratio, mean age, mean duration of disease, mean weight, mean BMI value, and residence of children in the two groups were not significantly different (P > 0.05); after treatment, the study group obtained significantly lower symptom scores and shorter disappearance time of clinical symptoms when comparing with the reference group (P < 0.001); the total clinical effective rate of the study group was significantly higher than that of the reference group (P < 0.05); the treated serum 5-HT and NO levels of children in both groups were significantly lower than those before treatment (P < 0.05), and in the between-group comparison, those of the study group were significantly lower (P < 0.05); and the treated AP, FP, and normal slow wave ratio of gastric antrum and body were significantly higher in the study group than in the reference group (P < 0.05). Conclusion The combination therapy of acupuncture and TCM application is a reliable method for improving the clinical symptoms in FD children. This strategy greatly reduces the levels of serum factors in child patients and shortens the corresponding treatment time. Further research will be conducive to establishing a better solution for such patients.

Palmitoylethanolamide Counteracts Enteric Inflammation and Bowel Motor Dysfunctions in a Mouse Model of Alzheimer's Disease. Front Pharmacol 2021; 12:748021. [PMID: 34658885 PMCID: PMC8511319 DOI: 10.3389/fphar.2021.748021] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 09/20/2021] [Indexed: 12/20/2022] Open
Abstract
Palmitoylethanolamide (PEA), an endogenous lipid mediator, is emerging as a promising pharmacological agent in multiple neurodegenerative disorders for its anti-inflammatory and neuroprotective properties. However, its effects on enteric inflammation and colonic dysmotility associated with Alzheimer’s disease (AD) are lacking. This study was designed to investigate the beneficial effect of PEA administration in counteracting the enteric inflammation and relieving the bowel motor dysfunctions in an AD mouse model, SAMP8 mice. In addition, the ability of PEA in modulating the activation of enteric glial cells (EGCs), pivotally involved in the pathophysiology of bowel dysfunctions associated with inflammatory conditions, has also been examined. SAMP8 mice at 4 months of age were treated orally with PEA (5 mg/kg/day) for 2 months. SAMR1 animals were employed as controls. At the end of treatment, parameters dealing with colonic motility, inflammation, barrier integrity and AD protein accumulation were evaluated. The effect of PEA on EGCs was tested in cultured cells treated with lipopolysaccharide (LPS) plus β-amyloid 1–42 (Aβ). SAMP8 treated with PEA displayed: 1) an improvement of in vitro colonic motor activity, citrate synthase activity and intestinal epithelial barrier integrity and 2) a decrease in colonic Aβ and α-synuclein (α-syn) accumulation, S100-β expression as well as enteric IL-1β and circulating LPS levels, as compared with untreated SAMP8 mice. In EGCs, treatment with PEA counteracted the increment of S100-β, TLR-4, NF-κB p65 and IL-1β release induced by LPS and Aβ. These results suggest that PEA, under a condition of cognitive decline, prevents the enteric glial hyperactivation, reduces AD protein accumulation and counteracts the onset and progression of colonic inflammatory condition, as well as relieves intestinal motor dysfunctions and improves the intestinal epithelial barrier integrity. Therefore, PEA represents a viable approach for the management of the enteric inflammation and motor contractile abnormalities associated with AD.

Abstract
Objective To evaluate gastric emptying (GE) and colonic transit in a cohort of patients with Parkinson disease and other parkinsonism disorders and to determine whether abnormal gut transit precedes motor onset of parkinsonism. Methods Medical record review of 84 patients with parkinsonism who underwent clinically indicated transit studies at Mayo Clinic (2001-2019) and 11 patients with transit studies who subsequently developed parkinsonism. Data are summarized as median (interquartile range). Results The 84 patients (52% female) with parkinsonism were aged 72 (66-76) years with a disease duration of 5 (2-8) years: Parkinson disease = 70, multiple system atrophy = 7, dementia with Lewy bodies = 4, progressive supranuclear palsy = 2, and parkinsonian syndrome = 1. Ten had delayed GE, 10 slow colonic transit, 16 accelerated GE (14 Parkinson disease, 1 multiple system atrophy, and 1 parkinsonian syndrome), and 49 normal transit. One patient with parkinsonian syndrome had both slow colonic and accelerated gastric transit. Longer disease duration and higher levodopa equivalent daily dose were observed for Parkinson disease compared with other parkinsonisms and with slow compared with normal colonic transit. Of 11 patients (5 female) with transit studies who later developed motor parkinsonism after 4 (3-5) years, 1 had accelerated GE, 1 had delayed GE, and 1 had both delayed GE and colonic transit. Conclusions Accelerated GE was newly identified in patients with parkinsonism, in addition to delayed GE or colonic transit. Furthermore, gut dysmotility was objectively identified to precede the motor onset of parkinsonism.

Abstract
INTRODUCTION A phase 2b clinical trial, HEADWAY-DLB, was performed to assess treatment with intepirdine, a serotonin receptor antagonist, in patients with dementia with Lewy bodies (DLB). METHODS HEADWAY-DLB was a multinational, double-blind, randomized, placebo-controlled study. Two hundred sixty-nine DLB patients were randomized to receive placebo, 70 mg/day intepirdine, or 35 mg/day intepirdine over 24 weeks. The primary endpoint was change from baseline to week 24 on the Unified Parkinson's Disease Rating Scale-Part III (UPDRS-III). RESULTS Both intepirdine groups did not demonstrate significant benefits over placebo at 24 weeks on the UPDRS-III (35 mg/day: P = .1580, 70 mg/day: P = .6069). All other endpoints were not significant. Intepirdine was well tolerated, with a slightly higher incidence of gastrointestinal adverse events observed in the intepirdine groups versus placebo. DISCUSSION Intepirdine treatment did not lead to improvements over placebo in patients with DLB. As one of the largest DLB studies to date, HEADWAY-DLB demonstrates that international trials for DLB are feasible within a reasonable timeframe.

Abstract
PURPOSE OF REVIEW This article provides an overview of the clinical presentation, investigations, and treatment options for gastrointestinal tract (GIT) dysfunction in patients with Parkinson's disease (PD) and other movement disorders. RECENT FINDINGS GIT dysfunction commonly appears as constipation and fecal incontinence (mostly overflow, accompanied with sphincter failure in multiple system atrophy [MSA]). Bowel dysfunction (underactive) occurs irrespectively from the site of the neurologic lesion, which is in contrast to site-dependent bladder dysfunction (brain, overactive; periphery, underactive). GI emergencies may arise, including intestinal pseudo-obstruction, intussusception, volvulus, and stercoral ulcer (ulcer of the colon due to pressure and irritation resulting from severe, prolonged constipation). Bowel function tests in neurologic patients often show a combination of slow transit and anorectal dysfunction. Management for slow transit constipation includes bulking agents, softening agents, yogurt/probiotics, and prokinetic agents. Suppositories, botulinum toxin injections, and transanal irrigation are options for managing anorectal constipation. CONCLUSIONS Function of the bowel is commonly affected in PD and other movement disorders. Neurologists play an important role in assessing bowel symptoms in their patients and planning treatment strategies, often in collaboration with specialist teams.

Abstract
Dementia with Lewy bodies and Parkinson's disease dementia, jointly known as Lewy body dementia, are common neurodegenerative conditions. Patients with Lewy body dementia present with a wide range of cognitive, neuropsychiatric, sleep, motor, and autonomic symptoms. Presentation varies between patients and can vary over time within an individual. Treatments can address one symptom but worsen another, which makes disease management difficult. Symptoms are often managed in isolation and by different specialists, which makes high-quality care difficult to accomplish. Clinical trials and meta-analyses now provide an evidence base for the treatment of cognitive, neuropsychiatric, and motor symptoms in patients with Lewy body dementia. Furthermore, consensus opinion from experts supports the application of treatments for related conditions, such as Parkinson's disease, for the management of common symptoms (eg, autonomic dysfunction) in patients with Lewy body dementia. However, evidence gaps remain and future clinical trials need to focus on the treatment of symptoms specific to patients with Lewy body dementia.
