Diagnostic Criteria in the Diagnosis of Spinal Spondyloarthropathies in Patients With Chronic Low Back Pain (Study P05320)(COMPLETED)

January 20, 2016 updated by: Merck Sharp & Dohme LLC

Observational Trial on the Value of Diagnostic Criteria in the Diagnosis of Spinal Spondyloarthropathies in Patients With Chronic Low Back Pain

This is a multi-national, multi-site, observational study to determine which of two strategies, when used by referring physicians is superior in the diagnosis of axial spondyloarthritis (AS) by rheumatologists.

Study Overview

Conditions

Detailed Description

Subjects will be selected using a non-probability sampling method. For each center of excellence, the local network of referring physicians will be assigned, according to a random code in a 1:1 ratio, to use one of the two referral strategies for eligible patients.

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.

Study Population

Each of several participating national centers of excellence will establish a network with local primary care physicians or their equivalent who will work with the center of excellence and will provide referrals of suitable patients.

Description

Inclusion Criteria:

  • A subject must have back pain of unknown origin, of more than 3 months' duration, and with onset before age 45.
  • A subject must be willing to give written informed consent and be able to adhere to visit schedules.

Exclusion Criteria:

  • Established diagnosis of spondyloarthropathies at the time of referral.
  • Any clinically significant condition or situation, other than the condition being studied, that, in the opinion of the investigator, would interfere with the study evaluations or optimal participation in the study.

Design Details

Cohorts and Interventions

Group / Cohort
Referral Strategy 1

Patient meets at least one of the following three criteria:

  1. Inflammatory back pain
  2. Human leukocyte antigen B27 (HLA-B27)
  3. Sacroiliitis demonstrated by imaging (X-ray, magnetic resonance imagining [MRI], bone scan [if previously available])
Referral Strategy 2

Patient meets at least two of the following six criteria:

  1. Inflammatory back pain
  2. HLA-B27
  3. Sacroiliitis (on imaging)
  4. Family history of AS
  5. Good response of back pain to nonsteroidal anti-inflammatory drugs (NSAIDs)
  6. Known Extra Articular Manifestations (Uveitis, Iridocyclitis, Psoriasis, Inflammatory Bowel Disease)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
To determine which of two referral strategies, when used by referring physicians, is superior in the diagnosis of AS by rheumatologists.
Time Frame: Approximately 3-6 months
Approximately 3-6 months

Secondary Outcome Measures

Outcome Measure
Time Frame
To determine which of the referral criteria proposed, or which combination of referral criteria, is the most successful and workable in the diagnosis of AS when used by referring physicians.
Time Frame: Approximately 3-6 months
Approximately 3-6 months
To describe the demographics and disease characteristics of patients diagnosed with AS.
Time Frame: Approximately 3-6 months
Approximately 3-6 months
To compare patient-derived data with physician data to determine whether the former alone can serve as effective screening for AS.
Time Frame: Approximately 3-6 months
Approximately 3-6 months
