Is this trial a fit for you?

Likely a good fit

Adults 18 and older with CKD on home peritoneal dialysis for at least 1 month are eligible.

Probably not a fit

Patients who do not respond biologically or who do not meet follow-up requirements may see no benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized, double-blind trial, adults on home peritoneal dialysis will receive daily synbiotic capsules or an identical placebo for six months. Researchers will measure inflammatory markers (CRP, ESR), uremic toxins (p-cresol, indoxyl sulfate), and malnutrition-inflammation status, plus track peritonitis episodes. Participants will have visits at baseline, 3 months, and 6 months for blood tests and nutritional assessments. The aim is to determine if synbiotics can improve gut-related biomarkers and clinical outcomes in this patient group.

Why it matters

Potential benefit: If successful, synbiotics could lower inflammation and possibly reduce infection risk and improve nutrition for people on peritoneal dialysis.

How similar studies have gone: Previous similar gut-targeted interventions have shown promise in CKD populations, but results are variable and this exact synbiotic combination is being tested in this setting.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients aged 18 years or older.
* Patients diagnosed with kidney disease who have been receiving peritoneal dialysis at home for at least 1 month.

Exclusion Criteria:

* Patients who are unable to eat or receive food through a feeding tube.
* Patients who have taken prebiotics or probiotics (supplements that support gut health) in the month before the study starts.
* Patients who used antibiotics in the month before the study starts.
* Patients who cannot attend the scheduled follow-up visits (missing the second follow-up appointment will result in being removed from the study).
* Note on non-adherence and withdrawal: Patients who are unable to take their assigned capsules regularly (taking less than 80% of the total capsules will result in being removed from the study).
