November 29, 2023 updated by: zahra yari, National Nutrition and Food Technology Institute

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Active Comparator: synbiotic
Patients in the synbiotic group will receive, for 10-12 weeks, Two capsules of synbiotic (Zist Takhmir Company) per day, each containing 500 mg of synbiotic. Patients in this group received a multispecies probiotic product (109 CFU/capsule) and fructo oligosaccharid as prebiotics.

Placebo Comparator: placebo
Patients in the placebo group will receive Two capsules of placebo containing maltodextrin per day. The placebo powder will comparable in color, texture, and taste to the synbiotics. Supplement packaging will be done by Zist Takhmir Company.
Other: placebo
Two capsules of placebo containing maltodextrin per day
