Synovial Fluid Bank From Arthritic Patients

May 13, 2026 updated by: Gilles Boire

Establishment of a Bank of Synovial Fluids and Paired Sera From Arthritic Patients for the Evaluation of New Methods Facilitating the Diagnosis and the Monitoring of Progression and Therapy of Arthritis.

The objectives of this group project is to collect synovial fluid (SF) and paired sera and carry out preclinical studies to evaluate, alone or by combination testings, the potential of novel biomarkers for their prevalence and diagnostic/prognostic values in patients with arthritis, and to determine how therapeutic intervention regulate their levels.

Detailed Description

Our group has developed interdisciplinary expertise in biomarkers related to distinct aspects of inflammation-induced joint damage, most notably those associated with degradation of components of the extracellular matrix, bone loss, or associated with post-translational changes on protease inhibitors.

The objectives of this group project is to collect SF and paired sera and carry out preclinical studies to evaluate, alone or by combination testings, the potential of novel biomarkers for their prevalence and diagnostic/prognostic values in patients with arthritis, and to determine how therapeutic intervention regulate their levels.

More specifically, we will study (1) biomarkers associated with osteoclastic bone resorption and synthesis/degradation of cartilage, (2) inhibitors of enzymes (calpastatin) that are preferentially targeted by rheumatoid patients, as well as (3) enzymes (e.g. Matrix Metalloproteinases (MMPs)) responsible for the cleavage of components of the articular cartilage.

Finally, we propose to characterize the repertoire of specific active proteases in the SF of arthritic patients concomitantly to the use biomarkers (neoepitopes of cleaved collagens) previously associated with cartilage destruction and synthesis to identify new targets for the development of protease inhibitors for the treatment of arthritis. Furthermore, our project will also provide the opportunity to test the potential of measuring the net proteolytic activity by Fluorescent-Activated Substrate Conversion as a method of monitoring disease activity and treatment efficiency in a clinical setting.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 years to 95 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

patients suffering from various arthritides (rheumatoid arthritis, gout and other microcristalline arthritides, osteoarthritis, spondylarthropathies, juvenile idiopathic arthritis, and various other diseases, including inflammatory polyarthritis of recent-onset in adults

Description

Inclusion Criteria:

  • Significant joint effusion

Exclusion Criteria:

  • Hemorrhagic effusion
  • Traumatic effusion

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2002

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
