Study summary

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.

Study population

arthritis patients

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age >18 years
  • arthritis in one or more joints as assessed by the treating rheumatologist, including RA, SpA, connective tissue disease and OA.

Exclusion criteria

Exclusion Criteria:

  • Known allergies to local anesthetics
  • Family history of bleeding, history of increased bleeding tendency or prolonged bleeding, current treatment with oral anticoagulants or aggregation inhibitors; Quick \< 65%, (INR) ≥ 1.3, thrombocyte count \< 100'000/μl, activated partial thromboplastin time (aPTT) > 37 sec
  • Inability or insufficient knowledge of project language to understand the information given in the form
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Grade of synovitis

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

    Time frame: 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

    Time frame: 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.

    Time frame: immediately after collection to study completion, up to 5 years
