Faecal Microbiota in Patients with Neurogenic Bowel Dysfunction and Spinal Cord Injury or Multiple Sclerosis-A Systematic Review. J Clin Med 2021; 10:jcm10081598. [PMID: 33918927 PMCID: PMC8068808 DOI: 10.3390/jcm10081598] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 03/19/2021] [Accepted: 04/04/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Neurogenic bowel dysfunction (NBD) frequently occurs in patients with spinal cord injury (SCI) and multiple sclerosis (MS) with comparable symptoms and is often difficult to treat. It has been suggested the gut microbiota might influence the course of NBD. We systematically reviewed the literature on the composition of the gut microbiota in SCI and MS, and the possible role of neurogenic bowel function, diet and antibiotic use. Methods: A systematic search was conducted in PubMed and Embase, which retrieved studies on the gut microbiota in SCI and MS. The Newcastle–Ottawa Quality Assessment Scale (NOS) was used to assess methodological quality. Results: We retrieved fourteen papers (four on SCI, ten on MS), describing the results of a total of 479 patients. The number of patients per study varied from 13 to 89 with an average of 34. Thirteen papers were observational studies and one study was an intervention study. The studies were case control studies in which the gut microbiota composition was determined by 16S rRNA gene sequencing. The methodological quality of the studies was mostly rated to be moderate. Results of two studies suggested that alpha diversity in chronic SCI patients is lower compared to healthy controls (HC), whereas results from five studies suggest that the alpha diversity of MS patients is similar compared to healthy subjects. The taxonomic changes in MS and SCI studies are diverse. Most studies did not account for possible confounding by diet, antibiotic use and bowel function. Conclusion: Based on these 14 papers, we cannot draw strong conclusions on the composition of the gut microbiota in SCI and MS patients. Putatively, alpha diversity in chronic SCI patients may be lower compared to healthy controls, while in MS patients, alpha diversity may be similar or lower compared to healthy controls. Future studies should provide a more detailed description of clinical characteristics of participants and of diet, antibiotic use and bowel function in order to make valid inferences on changes in gut microbiota and the possible role of diet, antibiotic use and bowel function in those changes.

Abstract
STUDY DESIGN Multi-centre, double-blind randomised placebo-controlled study. OBJECTIVE To investigate whether the use of a multispecies probiotic can prevent antibiotic-associated diarrhoea in people with spinal cord injury (SCI). SETTING Three Dutch SCI rehabilitation centres. METHODS Fifty-six people aged 18-75 years with SCI during inpatient rehabilitation, who require antibiotics, will be given probiotics or placebo randomly assigned (T0). After cessation of the antibiotics (T1), the participants will use probiotics/placebo for 3 more weeks (T2). Defaecation, assessed by the Bristol Stool Scale, and bowel management will be monitored daily until 2 weeks after cessation of probiotics/placebo intake (T3). Also, the degree of nausea and information on quality of life will be collected at T0, T1, T2 and T3. MAIN OUTCOME MEASURES The difference between the incidence of antibiotic-associated diarrhoea between people with SCI using probiotics compared to those using a placebo at the moment the antibiotics stops, the probiotics stops and two weeks thereafter. SECONDARY OUTCOME MEASURES The time to reach effective bowel management, degree of nausea and quality of life. REGISTRATION The Dutch Trial Register- NTR 5831.

Abstract
BACKGROUND Patients with spinal cord injury (SCI) who carry indwelling urinary catheters have an increased risk of urinary tract infection (UTI). Antiseptic silver alloy-coated (SAC) silicone urinary catheters prove to be a promising intervention to reduce UTIs; however, current evidence cannot be extrapolated to patients with SCI. PURPOSE This study aimed to assess the efficacy of SAC urinary catheters for preventing catheter-associated urinary tract infections. DESIGN/SETTING This is an open-label, multicenter (developed in Spain, Portugal, Chile, Turkey, and Italy), randomized clinical trial conducted in 14 hospitals from November 2012 to December 2015. PATIENT SAMPLE Eligible patients were men or women with traumatic or medical SCI, aged ≥18 years, requiring an indwelling urinary catheter for at least 7 days. OUTCOME MEASURES The primary outcome was the incidence of symptomatic UTIs. The secondary outcome included bacteremia in the urinary tract and adverse events. MATERIALS AND METHODS Patients were randomized to receive a SAC urinary catheter (experimental group) or a standard catheter (control group) for at least 7 days. Data were compared using chi-squared test and also calculating the absolute risk difference with a 95% confidence interval. An adjusted analysis including different risk factors of UTI was performed. This study was mainly funded by La Marató de TV3 Foundation (grant number # 112210) and the European Clinical Research Infrastructures Network organization. The funders had no role in the interpretation or reporting of results. RESULTS A total of 489 patients were included in the study, aged 55 years in the experimental group and aged 57 in the control group (p=.870); 72% were men; 43% were hospitalized patients, and 57% were outpatients (p=1.0). The most frequent cause of SCI was traumatic (73.75%), and the localization was mainly the cervical spine (42.74%). Most of the patients had an A score (complete spinal injury and no motor and sensory is preserved) on the ASIA scale (62.37%). The median time of urethral catheterization was 27 days in the experimental group and 28 days in the control group (p=.202). Eighteen patients (7.41%) in the experimental group and 19 in the control (7.72%) group had a symptomatic UTI (odds ratio [OR] 0.96 [0.49-1.87]). The adjusted analysis revealed no change in the results. Only three patients in the experimental group had bacteremia within the urinary tract. The experimental group presented more adverse events related to the use of a catheter than the control group (OR 0.03 [0.00-0.06]). CONCLUSIONS The results of this study do not support the routine use of indwelling antiseptic SAC silicone urinary catheters in patients with SCI. However, UTIs associated to long-term urinary catheter use remain a challenge and further investigations are still needed.

Abstract
BACKGROUND Controlling bias is key to successful randomized controlled trials for behaviour change. Bias can be generated at multiple points during a study, for example, when participants are allocated to different groups. Several methods of allocations exist to randomly distribute participants over the groups such that their prognostic factors (e.g., socio-demographic variables) are similar, in an effort to keep participants' outcomes comparable at baseline. Since it is challenging to create such groups when all prognostic factors are taken together, these factors are often balanced in isolation or only the ones deemed most relevant are balanced. However, the complex interactions among prognostic factors may lead to a poor estimate of behaviour, causing unbalanced groups at baseline, which may introduce accidental bias. METHODS We present a novel computational approach for allocating participants to different groups. Our approach automatically uses participants' experiences to model (the interactions among) their prognostic factors and infer how their behaviour is expected to change under a given intervention. Participants are then allocated based on their inferred behaviour rather than on selected prognostic factors. RESULTS In order to assess the potential of our approach, we collected two datasets regarding the behaviour of participants (n = 430 and n = 187). The potential of the approach on larger sample sizes was examined using synthetic data. All three datasets highlighted that our approach could lead to groups with similar expected behavioural changes. CONCLUSIONS The computational approach proposed here can complement existing statistical approaches when behaviours involve numerous complex relationships, and quantitative data is not readily available to model these relationships. The software implementing our approach and commonly used alternatives is provided at no charge to assist practitioners in the design of their own studies and to compare participants' allocations.
