About this study

Haematopoietic stem cell transplantation (HSCT) is a potentially lifesaving treatment option for various diseases. It involves infusion of stem cells after a conditioning regimen of chemotherapy with or without total body irradiation. There is a concern that HSCT and accompanying treatments may increase the risk for oral complications. Nevertheless, longitudinal studies measuring oral health before and after HSCT are scarce. Hence, we formulated the following research question:

In adult HSCT recipients, do oral health parameters change from baseline (pre-HSCT) to 3 - 24 months post-HSCT, and is the type of conditioning regimen associated with this change in oral health parameters?

To answer this research question, we will use data from the electronic health records of the Radboudumc (Epic and Dentium). We will include at least seventy-five adult patients who are examined both before and after HSCT at the department of Dentistry (Radboudumc) as part of an oral care program. The following oral health parameters were assessed: status praesens, pocket probing depth, bleeding on probing, periodontal epithelial surface area, periodontal inflamed surface area, xerostomia, unstimulated and stimulated salivary flow rate and pH, cariesactivity, oral chronic Graft-versus-Host Disease and dental treatments.

Patients were subjected to different regimens in preparation for HSCT, namely myeloablative, reduced intensity or non-myeloablative conditioning. To estimate the association between conditioning regimen and the change in oral health parameters, we will use mixed effects models with random effects, adjusted for potential confounders. Results will be reported as regression coefficients with corresponding 95% confidence intervals.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Haematopoietic stem cell transplantationProcedure or surgery

    Haematopoietic stem cell transplantation (HSCT) is widely used in the treatment of malignant and non-malignant conditions to reconstitute the immune system secondary to cytotoxic conditioning regimens. These regimens, consisting of chemotherapy with or without total body irradiation, cause severe immunosuppression prior to, during and after HSCT. Immune reconstitution takes place by infusion of stem cells either harvested from the patient (autologous HSCT) or from a donor (allogeneic HSCT).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of teeth

    Number of teeth (range 0 - 32)

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  2. Number of restorations

    Total number of restored tooth surfaces

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  3. Pocket probing depth

    Pocket probing depth at 6 sites per tooth in millimetres

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  4. Bleeding on probing

    Profound bleeding on probing at 6 sites per tooth as yes or no

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  5. Unstimulated and chewing stimulated salivary flow rate

    Whole mouth saliva, measured in mL/min

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  6. Unstimulated and chewing stimulated salivary pH

    Whole mouth saliva, measured with pH strips

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

Secondary outcomes (8)
  1. Periodontal Epithelial Surface Area

    The root surface area in square millimetres affected by attachment loss

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  2. Periodontal Inflamed Surface Area

    The root surface area in square millimetres affected by attachment loss and inflamed periodontal tissue

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  3. Xerostomia

    Subjective oral dryness measured by Xerostomia Inventory questionnaire

    Measured: Change from baseline (pre-HSCT) up to 24 months after HSCT

  4. Cariesactivity

    Likelihood for development of new caries lesions based on notes recorded by the dentist

    Measured: Up to 24 months after HSCT

  5. Oral chronic Graft-versus-Host Disease

    Assessed with National Institute of Health Oral Mucosal Score (range 0 - 15), higher score means more severe oral manifestations of oral chronic Graft-versus-Host Disease

    Measured: Up to 24 months after HSCT

  6. Extractions

    Total number of removed teeth (range 0 - 32)

    Measured: Between baseline (pre-HSCT) and up to 24 months after HSCT

  7. Periodontal care

    Number of participants per type of periodontal care, categorised in sub- and supragingival cleaning, subgingival cleaning, no cleaning

    Measured: Between baseline (pre-HSCT) and up to 24 months after HSCT

  8. Preventive measures

    Number of participants per type of preventive measure as fluoride varnish and oral hygiene instructions

    Measured: Between baseline (pre-HSCT) and up to 24 months after HSCT

Questions about this trial

What is this clinical trial studying?

An observational study of Stem Cell Transplant Complications and Oral Complication, run by Radboud University Medical Center at 1 site in Netherlands.

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 3 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 26 Oct 2022. 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 Netherlands. 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. 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?

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?

Number of teeth (time frame: Change from baseline (pre-HSCT) up to 24 months after HSCT). The study lists 6 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 26 Oct 2022.
