Sputum Studies of Anti-Citrullinated Protein Antibodies (ACPA) and Rheumatoid Arthritis (RA) Origins

Sputum Studies of Anti-Citrullinated Protein Antibodies (ACPA) and Rheumatoid Arthritis (RA) Origins

Recruiting
18 years and older
All
Phase N/A

The Specific Aims of This Study Are As Follows:

  1. Identify whether sputum anti-CCP predicts incident RA
  2. Determine the effect of inflammatory cytokines on the induction of NETosis in sputum neutrophils
  3. Determine the role of sputum macrophage phagocytosis in NET clearance <br> The knowledge gained from this study will improve the overall understanding of the development of RA. It is anticipated that these findings will improve the field's understanding of how best to screen for RA risk and target RA prevention. This study could support future lung-targeted prevention strategies for RA that could avoid the administration of systemic toxic therapies. Such potential prevention interventions could be implemented in subjects at risk for RA in order to prevent the irreversible joint damage that can occur in the later stages of clinically-apparent RA.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
