Sonographic Signs of Gouty Arthritis in a Cohort of Egyptian Patients: a Cross Sectional Multicenter Study

May 2, 2021 updated by: Ahmed Mahrous, Sohag University
The study is a cross sectional observational multicenter study. It is established in collaboration with the Egyptian college of rheumatology study group (ECRsg). It is conditioned that all the study participants had either mono- or oligo-arthritis with effusion of the knee or the first metatarsophalangeal (MTP) joint in patients with a known history of gout or at high risk. Patients with any known chronic arthritis, comprising rheumatoid arthritis, Sjogren's syndrome, systemic lupus erythematosus, scleroderma, neuropathic arthritis, seronegative spondyloarthropathy, will be excluded from the study. None of the participants had a history of intra-articular injection or aspiration in the scanned joints for 3 months prior to the inclusion in the study. The sonographers will be blinded for clinical data and the EULAR scanning protocol for the knee and 1st MTP will be considered [2]. Further, scanning of the double contour sign over the femur condyles anteriorly and posteriorly in sagittal planes will be assessed. All the sonographers in the study had an experience between 5 and 10 years in the field of musculoskeletal ultrasound.

Study Overview

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.

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

40 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study population will be collected from several university clinics all over Egypt. All are aged 40 or more with a history of definite gouty arthritis or at high risk and they have active arthritis of at least one joint.

Description

Inclusion Criteria:

  • mono- or oligo-arthritis with effusion of the knee or the first metatarsophalangeal
  • patients with a known history of gout or at high risk

Exclusion Criteria:

  • Patients with any known chronic arthritis, comprising rheumatoid arthritis, Sjoegren's syndrome, systemic lupus erythematosus, scleroderma, neuropathic arthritis, seronegative spondyloarthropathy
