Trial summary

Rheumatoid arthritis (RA) has been proved to increase the incidence of atrial fibrillation (AF) with persistent systemic inflammation. Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been found to enhance the production of pro-inflammatory cytokines. Read more about this study

About this study

Official title: The Expression of Proprotein Convertase Subtilisin Kexin 9 in Patients With Rheumatoid Arthritis Combined Atrial Fibrillation

Rheumatoid arthritis (RA) has been proved to increase the incidence of atrial fibrillation (AF) with persistent systemic inflammation. Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been found to enhance the production of pro-inflammatory cytokines. Therefore, we performed the present study to observe the expression and significance of proprotein convertase subtilisin kexin 9 (PCSK9) in patients with RA combined atrial fibrillation.

Read the detailed description

Atrial fibrillation (AF), the most common clinically relevant arrhythmia, is an important contributor to population morbidity and mortality. Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease, which affects approximately 1% of the population. Increasing studies demonstrated that RA had a positive correlation with increased cardiovascular diseases. Increasing studies showed that the prevalence of AF is significantly higher in RA patients than in the general population. Recently, some studies indicated that proprotein convertase subtilisin/kexin type 9 (PCSK9) promotes inflammatory by regulating macrophage secretion of inflammatory cytokines, inducing C-reaction protein (CRP), interleukin (IL)-6, IL-8, tumor necrosis factor-α (TNF-α) and so on. However, the levels of PCSK9 in atrial fibrillation patients with rheumatoid arthritis is still unclear. Therefore, the aim of this study was to assess the expression of PCSK9 in patients with RA combined atrial fibrillation.

Questions about this trial

What is this clinical trial studying?

An observational study of PCSK9, run by First Affiliated Hospital of Harbin Medical University at 2 sites in China.

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 4 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 13 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. 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?

Contact Meijiao He, Doctor (86-451-85555673, hemeijiao99@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The expression of PCSK9 in patients with RA combined with AF (time frame: One year). 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 13 Jan 2022; AzTrials last refreshed its copy on 7 Nov 2026.
