About this study

Official title: Causal Association Between Rheumatoid Arthritis and Periodontitis: A Mendelian Randomization Study

This study aims to investigate the causal relationship between rheumatoid arthritis and periodontitis using Mendelian randomization. Data will be sourced from genome-wide association studies (GWAS) to explore genetic associations and assess potential risk factors in an East Asian population.

Read the detailed description

The purpose of this study is to explore the causal association between rheumatoid arthritis (RA) and periodontitis using Mendelian randomization (MR). RA and periodontitis share similar inflammatory pathways and immune responses, but their causal relationship remains unclear. This study will utilize genome-wide association studies (GWAS) data from an East Asian population to identify single nucleotide polymorphisms (SNPs) associated with RA and assess their potential impact on the risk of developing periodontitis. Statistical methods such as inverse-variance weighting, MR-Egger regression, and weighted median analysis will be employed to analyze the data. The findings may provide insights into the shared genetic basis and causal relationships between these two conditions, offering potential targets for preventive strategies.

What is being measured

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

  1. Causal Association Between Rheumatoid Arthritis and Periodontitis

    This study uses Mendelian randomization to evaluate the causal relationship between rheumatoid arthritis (RA) and periodontitis in the East Asian population. The analysis utilizes genome-wide association study (GWAS) data, employing inverse variance weighting (IVW), weighted median, and MR-Egger regression methods to assess the genetic relationship and the risk contribution of RA to the development of periodontitis.

    Measured: Data collected from 2023 to 2024.

Secondary outcomes (1)
  1. Analysis of Genetic Pleiotropy and Confounders

    Evaluation of the presence of genetic pleiotropy and its potential effect on the association between rheumatoid arthritis and periodontitis.

    Measured: 2023 to 2024

Questions about this trial

What is this clinical trial studying?

An observational study of Rheumatoid Arthritis and Periodontitis, run by Zhibin Xu.

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 2 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 20 Sep 2024. 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. 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?

Causal Association Between Rheumatoid Arthritis and Periodontitis (time frame: Data collected from 2023 to 2024.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06603207, which also lists 1 linked publication.

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 20 Sep 2024.
