Background: Few studies have analized the persistence of ultrasound (US) abnormalities in patients (pts) with Psoriatic Artritis (PA) during the phase of minimal disease activity (MDA) Objectives: To investigate the prevalence of US alterations at enthesis, joint and tendon levels in pts with psoriatic arthritis (PA) during a phase of MDA. Methods: Pts treated with anti-tumor necrosis factor (TNF) for at least 12 months and with at least 6 months duration of MDA were consecutively recruited at 6 Italian centers. In every center, the local rheumatologists provided PA pts to be examined by US. Personal history, demographic and clinical data were recorded. Each patient underwent the following US examinations: metacarpophalangeal (MCP), knee and tibio-tarsal (TT) joint, flexor and extensor tendon of hand digit, flexor and extensor tendon at carpal area, flexor and extensor tendon of foot, and enthesis of common extensor tendon insertion on the lateral epicondyle of the humerus, quadriceps tendon, patellar tendon, Achilles tendon and plantar fascia insertions on the calcaneus. Each examination were performed by rheumatologists expert in US, to assess synovitis (joint effusion, synovial proliferation, and power Doppler (PD) signal), and bone erosions, flexor tendon tenosynovitis, hand finger extensor tendon tenonitis, and enthesel involvement using an Esaote MyLabClass with a 5–13 or 6–18 MHz linear probe.

All US findings were scored using a 4 degree semiquantitative scoring system. US acute enthesitis was defined by the presence of entheseal edema or PD signal.

Abstract

Background: Few studies have analized the persistence of ultrasound (US) abnormalities in patients (pts) with Psoriatic Artritis (PA) during the phase of minimal disease activity (MDA) Objectives: To investigate the prevalence of US alterations at enthesis, joint and tendon levels in pts with psoriatic arthritis (PA) during a phase of MDA. Methods: Pts treated with anti-tumor necrosis factor (TNF) for at least 12 months and with at least 6 months duration of MDA were consecutively recruited at 6 Italian centers. In every center, the local rheumatologists provided PA pts to be examined by US. Personal history, demographic and clinical data were recorded. Each patient underwent the following US examinations: metacarpophalangeal (MCP), knee and tibio-tarsal (TT) joint, flexor and extensor tendon of hand digit, flexor and extensor tendon at carpal area, flexor and extensor tendon of foot, and enthesis of common extensor tendon insertion on the lateral epicondyle of the humerus, quadriceps tendon, patellar tendon, Achilles tendon and plantar fascia insertions on the calcaneus. Each examination were performed by rheumatologists expert in US, to assess synovitis (joint effusion, synovial proliferation, and power Doppler (PD) signal), and bone erosions, flexor tendon tenosynovitis, hand finger extensor tendon tenonitis, and enthesel involvement using an Esaote MyLabClass with a 5–13 or 6–18 MHz linear probe. The following elementary lesions were assessed at each enthesis: morphologic abnormalities (hypoechogenicity and/or thickening), entheseal calcific deposits, cortical abnormalities (bone erosion and/or proliferation), adjacent bursitis and intraenthesis and perienthesis (tendon body and/or bursa) PD signal. All US findings were scored using a 4 degree semiquantitative scoring system. US acute enthesitis was defined by the presence of entheseal edema or PD signal.
