Power Doppler in Hand Joints of Early RA Patients

February 15, 2021 updated by: Karine Rodrigues da Luz, Federal University of São Paulo

Power Doppler in Hand Joints is a Predictor of Therapeutic Failure in Women With Early Rheumatoid Arthritis Naive for Treatment

It is a prospective case-control study with women diagnosed early rheumatoid arthritis. Three therapeutic failures were considered: failure 1 - to the first Disease-modifying antirheumatic drugs (DMARDs) (methotrexate); failure 2 - to the second DMARDs (leflunomide) and failure 3 - to the first immunobiological drugs (adalimumab). Ultrasound was performed bilaterally on the 2nd and 3rd metacarpophalangeal joints (MCFs), proximal interphalangeal joints (IFPs), and wrists (US10). Ultrasound measurements (qualitative and semi-quantitative) evaluated: 1 - inflammatory: synovial and tenosynovial proliferation in gray scale and power Doppler (0-3); 2 - joint damage: bone erosion (qualitative and semi-quantitative) and cartilage damage (qualitative and semi-quantitative). Clinical and laboratory variables were also assessed blindly at baseline and after 12, 24 e 48 weeks.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Drug: Drug protocol

The following drug scheme was carried out: The patients began with methotrexate (MTX) 15 mg / week, which was increased to 25 mg / week until week 12. Subsequent steps for patients with an insufficient response (DAS28 score> 3.2 and the Physician's Global Assessment (PGA)> 4.0 [0-10 cm]) were leflunomide 20mg / day with MTX 15 mg / week from week 12 to week 24 and adalimumab twice a month and MTX 15mg / week from week 24 to week 48. The use of 5mg folic acid was advised once a week during the 48 weeks of the study. Three treatment failures were considered over these 48 weeks:

  • Failure 1: failure of the first DMARD (MTX) in week 12.
  • Failure 2: failure of the second DMARD (leflunomide) at week 24
  • Failure 3: failure of the first immunobiological (adalimumab) at week 48.

What is the study measuring?

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
Time Frame
Changes in Synovial blood flow (power doppler)
Time Frame: Baseline, after 4, 12, 24 and 48 weeks
Measured in ultrasound examination
Baseline, after 4, 12, 24 and 48 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

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.
