About this study

This study aims to study the inflammatory response in various forms of arthritis.

Read the detailed description

Arthritis, a significant heald burden is characterized by joint inflammation that severely impacts patients' quality of live. Despite advancements in treatment, many individuals with conditions like rheumatoid arthritis (RA), osteoarthritis (OA), and spondyloarthritis (SpA) do not achieve satisfactory outcomes, underscoring the need for more precise therapeutic strategies.

The project aims to characterize the inflammatory response in various form of arthritis by collecting and analyzing synovial tissue-the connective tissue lining joints. Biopsies will be collected through ultrasound-guided biopsies (UGSB), a minimally invasive and well-tolerated procedure. Presence of immune and stromal cells in the tissue, their interactions, and their relationship to clinical symptoms are characterized by histological and molecular methods. By comparing these features across different forms of arthritis, the study aims to identify molecular pathways and biomarkers that distinguish these diseases and their subtypes. The study hopes to contribute to a broader understanding of arthritis pathophysiology, ultimately translating into novel therapeutic targets and tailored clinical strategies.

What is being measured

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

  1. Grade of synovitis

    assessed by the Krenn score in the hematoxylin and eosin staining (Score 0-3, 0=normal, 3=severe)

    Measured: immediately after collection to study completion, up to 5 years

  2. classification pathotypes

    immunohistochemical staining with cell type specific markers including CD15, CD68, CD3, CD20, CD138 of the collected tissues from different arthritis subtypes

    Measured: immediately after collection to study completion, up to 5 years

  3. comparing transcriptomic signature

    single-cell RNA sequencing of collected tissues from different arthritis subtypes to identify disease specific biomarkers.

    Measured: immediately after collection to study completion, up to 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Arthritis and Arthritis, Rheumatoid, run by University Hospital, Basel, Switzerland.

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 3 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: opening soon, as of the sponsor's last update on 11 Apr 2025. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Diego Kyburz, Prof. Dr. (+41 61 328 74 81, diego.kyburz@usb.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Grade of synovitis (time frame: immediately after collection to study completion, up to 5 years). The study lists 3 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 11 Apr 2025.
