About this study
Official title: Effects of Synbiotic Supplement on Anthropometric Parameters, Cardiovascular Disease Risk Factors, and Bone Metabolism Markers in Transplanted Kidney Patients on Chronic Post-kidney Transplant Phase Diet
The aim of this double-blind randomized clinical trial is to determine the effects of synbiotic supplement on cardiovascular disease risk factors and bone metabolism markers and depression, in transplanted kidney patients on chronic post-kidney transplant phase diet.This study is a double-blind, randomized controlled clinical trial with two parallel groups. 44 patients will be randomly assigned into synbiotic and control group. Transplanted kidney patients referring to the hospital clinics will be invited to participate. After assessing the entrance criteria, 7 cc blood samples are taken. The food recall is completed. Supplements are given to patients for 10-12 weeks. Serum concentrations of malondialdehyde; high sensitivity c-reactive protein; Soluble intercellular adhesion molecule-1; glucose; pentosidine; carboxy-methyl lysine; osteoprotegerin; Receptor activator of nuclear factor kappa-Β ligand; N-telopeptide; Intact parathyroid hormone; triglyceride; total cholesterol; High-density lipoprotein cholesterol; low-density lipoprotein cholesterol; lipoprotein-a; albumin; calcium; phosphorous; blood nitrogen urea; creatinine; and also systolic blood pressure; diastolic blood pressure; Weight; Body mass index; Waist circumference; Hip circumference; and questionnaires including quality of depression.

Questions about this trial
What is this clinical trial studying?
A study testing synbiotic in people with Transplanted Kidney, run by National Nutrition and Food Technology Institute.
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 4 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 7 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact zahra yari, PhD (+982122357484, zahrayari_nut@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lp (a) (time frame: 10 weeks). The study lists 22 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 7 Dec 2023; AzTrials last refreshed its copy on 8 Nov 2026.
