Background:Even though cartilage loss is a known feature of psoriatic arthritis (PsA), research is sparse on its role in the pathogenesis of PsA and its potential use for disease detection and monitoring. Using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and dynamic contrast-enhanced MRI (DCE MRI), research has shown that early cartilage loss is strongly associated with synovial inflammation in rheumatoid arthritis (RA). The aim of this study was to determine if acute inflammation is associated with early cartilage loss in small finger joints of patients with PsA.Objectives:Is local perfusion in PsA patients measured by dynamic MRI associated to local cartilage loss?Methods:Metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints of 17 patients with active PsA were evaluated by high-resolution 3 Tesla dGEMRIC and DCE MRI using a dedicated 16-channel hand coil. Semi-quantitative and quantitative perfusion parameters were calculated. Images were analyzed by two independent raters for dGEMRIC indices, PsA MRI scores (PsAMRIS), total cartilage thickness (TCT), and joint space width (JSW).Results:We found significant negative correlations between perfusion parameters (except Kep) and dGEMRIC indices, with the highest value at the MCP joints (KTrans: τ = -0.54, p = 0.01; Kep: τ= -0.02, p = 0.90; IAUC: τ = -0.51, p = 0.015; Initial Slope: τ = -0.54, p = 0.01; Peak: τ = -0.67, p = 0.002). Heterogeneous correlations were detected between perfusion parameters and both, total PsAMRIS and PsAMRIS synovitis sub-scores. No significant correlation was seen between any perfusion parameter and JSW and/or TCT.Conclusion:As examined by DCE MRI and dGEMRIC, there is a significant association between early cartilage loss and acute synovial inflammation in small finger joints of PsA patients.Figure 1.dGEMRIC maps (third digit) and perfusion maps (peak parameter) of MCP, PIP, and DIP joints in 26-year-old male (A and B) and a 59-year-old female (C and D) with PsA. Lower dGEMRIC values are illustrated in D, indicating more proteoglycan loss than in A. Higher peak values are depicted in C, indicating a higher severity of synovitis than in B. Peak parameter is illustrated in mM/l per second, dGEMRIC indices in ms.Disclosure of Interests:Philipp Sewerin Grant/research support from: AbbVie Deutschland GmbH & Co.

Abstract Background/Aims  MAXIMISE, the first randomised controlled trial evaluating efficacy of a biologic for psoriatic arthritis (PsA) axial manifestations, showed that secukinumab 300 and 150 mg provided rapid and significant improvement in ASAS20 responses through Week 12. We report the effect of secukinumab on clinical and imaging outcomes through 52 weeks. Methods  This Phase 3, double-blind, multicentre trial included 498 patients (≥18 years) with PsA who fulfilled CASPAR criteria presenting with spinal pain VAS ≥40/100, BASDAI ≥4 and inadequate response to ≥ 2 non-steroidal anti-inflammatory drugs. Patients were randomised to secukinumab 300 mg (N = 167), 150 mg (N = 165) or placebo (N = 166) weekly for 4 weeks and every 4 weeks thereafter. At Week 12, placebo patients were re-randomised to secukinumab 300/150 mg. The primary endpoint was ASAS20 with secukinumab 300 mg at Week 12. Exploratory assessments at Week 52 included ASAS20/40, BASDAI50, spinal pain (VAS) and improvement in Berlin magnetic resonance imaging (MRI) score for spine and sacroiliac joints. Results  The primary endpoint was met. ASAS20/40 responses at Week 12 were 62.9%/43.6% (secukinumab 300 mg) and 66.3%/39.5% (secukinumab 150 mg) versus 31.2%/12.2% (placebo), respectively (P < 0.0001). ASAS20/40 responses improved further with secukinumab 300/150 mg from baseline through 52 weeks. 74.1%/74.7% and 63.0%/50.6% of placebo patients, re-randomised at Week 12 to secukinumab 300/150 mg, achieved ASAS20/40 at Week 52. At baseline, 59.5% (secukinumab 300 mg), 54.2% (secukinumab 150 mg) and 64.2% (placebo) of patients had positive MRI scores for the sacroiliac joints and/or the spine. Reductions in Berlin MRI scores for the entire spine and sacroiliac joints were sustained with secukinumab 300/150 mg from baseline through 52 weeks (Table 1). 64.6%, 69.1% and 33.6% of patients with inflammatory back pain at baseline, confirmed by ASAS, Calin et al. and Berlin criteria in the secukinumab 300 mg, 150 mg and placebo groups, respectively, achieved ASAS20 at Week 12.

Background:Even though cartilage loss is a known feature of psoriatic arthritis (PsA), little is known about its role in the pathogenesis of PsA. Using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) as a non-invasive marker of the tissue’s proteoglycan content, such early (i.e. pre-morphological) changes have been associated with inflammation in rheumatoid arthritis (RA). Yet, this association has not been studied before in PsA.Objectives:Is the severity of local joint inflammation associated to local proteoglycan loss in PsA patients?Methods:Metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints of 17 patients with active PsA were evaluated by high-resolution clinical standard morphological and dGEMRIC sequences using a 3T MRI scanner (Magnetom Skyra, Siemens) and a dedicated 16-channel hand coil. Images were analyzed by two independent raters for dGEMRIC indices, PsA MRI scores (PsAMRIS) and total cartilage thickness (TCT). Kendall-Tau correlation coefficients (τ) were calculated.Results:We found significant negative correlations between dGEMRIC indices and total PsAMRIS (τ = -0.5, p= 0.012), synovitis (τ = -0.56, p= 0.006), flexor tenosynovitis (τ = -0.4, p= 0.049), and periarticular inflammation (τ = -0.72, p< 0.001). Significant positive correlations were found between TCT and dGEMRIC indices in all joint levels (τ = 0.43, p<0.001). No significant correlations were determined between dGEMRIC indices and bone erosion, bone edema or bone proliferation.Conclusion:In PsA, proteoglycan loss as assessed by dGEMRIC is associated with periarticular inflammation, synovitis, and flexor tenosynovitis, but not with bone erosion or proliferation, thereby highlighting the need for effective anti-inflammatory treatment regimes. Beyond morphology, advanced MRI techniques may be used to assess cartilage composition in PsA and to identify early changes in cartilage as an imaging biomarker with potential application in detection and monitoring of PsA.Figure 1Right hand of a 26-year-old male with psoriatic arthritis Coronal STIR image (A) of digits 1-5, transversal fat-saturated (fs) T2-weighted image of digits 2-4 (B) and the corresponding transversal fs contrast-enhanced T1-weighted image (C) at the distal portion of the proximal phalanges.

Abstract Objectives Micro-computed tomography (μ-CT) and histology, the current gold standard methods for assessing the formation of new bone and blood vessels, are invasive and/or destructive. With that in mind, a more conservative tool, dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), was tested for its accuracy and reproducibility in monitoring neovascularization during bone regeneration. Additionally, the suitability of blood perfusion as a surrogate of the efficacy of osteoplastic materials was evaluated. Materials and methods Sixteen rabbits were used and equally divided into four groups, according to the time of euthanasia (2, 3, 4, and 6 weeks after surgery). The animals were submitted to two 8-mm craniotomies that were filled with blood or autogenous bone. Neovascularization was assessed in vivo through DCE-MRI, and bone regeneration, ex vivo, through μ-CT and histology. Results The defects could be consistently identified, and their blood perfusion measured through DCE-MRI, there being statistically significant differences within the blood clot group between 3 and 6 weeks (p = 0.029), and between the former and autogenous bone at six weeks (p = 0.017). Nonetheless, no significant correlations between DCE-MRI findings on neovascularization and μ-CT (r =−0.101, 95% CI [−0.445; 0.268]) or histology (r = 0.305, 95% CI [−0.133; 0.644]) findings on bone regeneration were observed. Conclusions These results support the hypothesis that DCE-MRI can be used to monitor neovascularization but contradict the premise that it could predict bone regeneration as well.

(1) Background: Blood brain barrier (BBB) disruption following traumatic brain injury (TBI) results in a secondary injury by facilitating the entry of neurotoxins to the brain parenchyma without filtration. In the current paper, we aimed to review previous dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies to evaluate the occurrence of BBB disruption after TBI. (2) Methods: In electronic databases (PubMed, Scopus, Embase, and the Cochrane Library), we searched for the following keywords: dynamic contrast-enhanced OR DCE AND brain injury. We included studies in which BBB disruption was evaluated in patients with TBI using DCE-MRI. (3) Results: Four articles were included in this review. To assess BBB disruption, linear fit, Tofts, extended Tofts, or Patlak models were used. KTrans and ve were increased, and the values of vp were decreased in the cerebral cortex and predilection sites for diffusion axonal injury. These findings are indicative of BBB disruption following TBI. (4) Conclusions: Our analysis supports the possibility of utilizing DCE-MRI for the detection of BBB disruption following TBI.

The potential of magnetic resonance imaging (MRI) for use in clinical practice and research has gained increasing interest over the last decade. International collaborative initiatives from GRAPPA (Group for Research and Assessment of Psoriasis and Psoriatic Arthritis) and/or OMERACT (Outcome Measures in Rheumatology) may contribute to facilitating research, identifying appropriate areas for use, and reaching consensus on the optimal examination technique. Accordingly, GRAPPA, a primary driver of international research in psoriasis and psoriatic arthritis (PsA), has focused on the current use and future development of MRI and other modern imaging modalities in PsA. This review, presented at the GRAPPA 2010 annual meeting, describes the current status of MRI in PsA, with a focus on its use in diagnosis, monitoring, and prediction of the disease course and treatment response. Important areas for future research are also outlined.
