About this study
Official title: Effect of Probiotics on Modulating the Bacterial Translocation and Improving Micro-inflammation in Hemodialysis Patients
Intestinal microbiota has recently emerged as an important player in the progression and complications of chronic kidney disease(CKD). And drug therapy which selects the gut as a target has raised lots of concern. It has been reported that the composition of intestinal flora has changed in uremic patients. Specifically, imbalanced ecosystem has higher number of pathogens such as Clostridia, Enterobacteria,and lower number of beneficial microbes such as Lactobacilli and Bifidobacteria. This modification of intestinal flora can strongly increase transformation of amino acids into Uremic Retention solutes, e.g., indoxyl-sulfate (IS), p-cresyl sulfate (PCS), which are so called gut-derived uremic toxins. The dysbiosis also contributes to an increase in intestinal permeability by disrupting the colonic epithelial tight junction,which may subsequently lead to translocation of endotoxin and bacteria into the host's internal environment,resulting in systemic micro-inflammation.Also all of these can promote the progression of renal failure and the incidence of cardiovascular complications,renal osteodystrophy and anemia.Probiotics is defined by the World Health Organization as 'live microorganisms that, when administered in adequate amounts, confer a health benefit on the host'. Probiotics are being increasingly used for various pathologic conditions.It is said that probiotics have a therapeutic role in maintaining a metabolically balanced gastrointestinal tract (GIT).And in our previous study,the investigators found that in uremic rats,lactobacillus acidophilus can relieve bacterial translocation and decrease the level of inflammatory markers.So our study is mainly designed to investigate whether probiotics can modulate the balance of intestinal ecosystem, prevent the bacterial translocation from gut and alleviate the systemic inflammation in hemodialysis(HD) patients.
Read the detailed description
This study is a single-centre, double-blind, placebo-controlled, randomised trial. Participants will undergo a 2 week run-in period, followed by randomisation to either probiotics supplements or placebo for 6 months. The study population are hemodialysis patients from Dialysis Department in First Affiliated Hospital of Xi'an Jiaotong University. The Dialysis Department have 400 patients who regularly come to receive dialysis therapy three times a week.It's relatively easy for us to follow up and collect data.Patients who meet the criteria and are able to provide informed consent will be recruited.Then computer-generated randomisation of participants to treatment order will be undertaken by an external statistical consultant. This process of allocation will conceal the randomisation order to researchers and participants. In addition, the supplements will be packed off-site with a generic label.
After randomization,baseline data will be collected and all participants will undergo face-to-face dietary education with a dietitian, incorporating standard hemodialysis education during the first week of run-in.In the week following, and throughout the intervention, patients will be encouraged to maintain stable protein and fibre intakes, with specific attention to maintaining the same sources of these nutrients.Participants' dietary intakes during the study will be assessed every month using a semi-quantitative food frequency questionnaire. And when the trial starts, questionnaires and biological samples will be performed and collected at the corresponding time. All serious adverse events will be reported to the ethics committee, whether deemed to be intervention related or not. Adherence to supplements will be measured by pill count every two weeks.
This study is an explorative clinical trial.And in the absence of any data about the effect of probiotics on hemodialysis patients intestinal and serum microbiota,sample size can't be calculated.Data will be reported as s mean±SD if normally distributed and as median(25-75% percentiles) if not. The Shapiro-Wilk test is performed to assess whether data are normally distributed. Statistical comparisons of normally distributed data are performed using Student's t-test. Mann-Whitney U-test is used to compare the rank variables measuring gastrointestinal symptoms in probiotics and placebo groups. The threshold for statistical significance is at p values <0.05. And an external statistical consultant from our Clinical Research Center will be involved in the data validation and analysis activities.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Intestinal microbiota has recently emerged as an important player in the progression and complications of chronic kidney disease(CKD). And drug therapy which selects the gut as a target has raised lots of concern. It has been reported that the composition of intestinal flora has changed in uremic patients. Specifically, imbalanced ecosystem has higher number of pathogens such as Clostridia, Enterobacteria,and lower number of beneficial microbes such as Lactobacilli and Bifidobacteria. This modification of intestinal flora can strongly increase transformation of amino acids into Uremic Retention solutes, e.g., indoxyl-sulfate (IS), p-cresyl sulfate (PCS), which are so called gut-derived uremic toxins. The dysbiosis also contributes to an increase in intestinal permeability by disrupting the colonic epithelial tight junction,which may subsequently lead to translocation of endotoxin and bacteria into the host's internal environment,resulting in systemic micro-inflammation.Also all of these can promote the progression of renal failure and the incidence of cardiovascular complications,renal osteodystrophy and anemia.Probiotics is defined by the World Health Organization as 'live microorganisms that, when administered in adequate amounts, confer a health benefit on the host'.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Bifid Triple Viable Capsules in people with Kidney Failure, Chronic, run by First Affiliated Hospital Xi'an Jiaotong University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Gut microbiota (time frame: Change from Baseline in faeces bacterial genomic DNA at 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02929225, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2018.
