Novel PAradigm to Improve Inflammatory Burden in ESRD (rePAIR): A Pilot and Feasibility Randomized Controlled Trial (rePAIR)

June 2, 2025 updated by: UConn Health

Pilot and Feasibility Clinical Research Grants in Kidney or Urologic Diseases (R21)

The goal of this project is to assess repeated and ongoing oral care and the way it may affect inflammation and quality of life in hemodialysis patients. Two treatment groups will be compared:

  • 1) ongoing and repeated gum disease therapy including deep tooth cleaning followed by multiple appointments of maintenance
  • 2) single session of gum disease therapy with only one session of deep tooth cleaning Samples of blood will be obtained for study to examine the changes of inflammatory substances in the blood as a result of the two different gum disease treatments. Also, a 14-question survey will be discussed with you to assess oral health related quality of life (OHIP-14) and the way it is affected by oral care.

For this project, four dialysis centers will be randomly assigned to either of the treatment groups #1 or #2 prior to your enrollment. For this purpose, there are two distinct consent forms explaining the visits, procedures and risks of the two treatment groups #1 or #2. As a result, all participants in the same dialysis center will belong to the same treatment group (either #1 or #2) and presented with the corresponding consent form.

This dialysis center has been randomized to treatment group # 1; therefore you will receive ongoing and repeated gum disease therapy including deep tooth cleaning followed by multiple appointments of maintenance.

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

66

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Patient must be referred by nephrologist
  • Patient must be diagnosed with ESRD and on Hemodialysis
  • life expectancy more than one year
  • at least 21 years of age
  • 12 or more teeth
  • must meet the Periodontal diagnosis criteria (The diagnosis of periodontitis is based on the definition of moderate periodontitis with at least 2 sites with CAL≥4mm or at least 2 sites with PD≥5mm not on the same tooth (Page and Eke 2007).)

Exclusion Criteria:

  • Anticipating a kidney transplant

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Test
Briefly, treatment sessions will include oral hygiene behavioral modification and scaling and root planning (removing the bacterial biofilm and calculus below the gum line) in order to eliminate etiologic factors and control periodontal inflammation. Once the treatment sessions are completed, the patients will enter the maintenance phase and will be followed for 6 months. In this phase, the patients will receive systematic and repeated supportive periodontal treatment (tooth cleanings above the gum line with re-enforcement of oral hygiene). Outcomes will be assessed at 2-, 4-, and 6-months. Throughout the course of the study, additional dental needs will be addressed with immediate referral to the subject's general dentist or clinics at the University of Connecticut.
Other: Test
Briefly, treatment sessions will include oral hygiene behavioral modification and scaling and root planning (removing the bacterial biofilm and calculus below the gum line) in order to eliminate etiologic factors and control periodontal inflammation. Once the treatment sessions are completed, the patients will enter the maintenance phase and will be followed for 6 months. In this phase, the patients will receive systematic supportive periodontal treatment (tooth cleanings above the gum line with re-enforcement of oral hygiene).
No Intervention: Control
The Control arm will receive only a single treatment session without maintenance sessions (see visit Table in Human Subject Protection section). Outcomes will be assessed at 2-, 4-, and 6-months.

What is the study measuring?
