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.

Background:To evaluate the glycosaminoglycan (GAG) content of lumbar intervertebral discs (IVD) in patients with ankylosing spondylitis (AS) using GAG chemical exchange saturation transfer (gagCEST).Objectives:Does local GAG content in non-degenerative IVDs measured by gagCEST MRI differs between AS patients and HC?Methods:195 lumbar IVD of 15 patients with AS (mean age 50 ±10 years) and 25 healthy control patients (HC) were prospectively examined with 3 T magnetic resonance imaging (MRI). MRI protocol contained morphological T2 weighted (T2w) images to grade IVD according to the Pfirrmann classification and biochemical imaging with gagCEST to calculate a region of interest (ROI) of the nucleus pulposus (NP) and annulus fibrosus (AF). Prior to statistical testing of gagCEST effects in patients and HC, IVD were classified according to Pfirrmann.Results:Significantly lower gagCEST values of NP and AF were found in non-degenerative IVD (Pfirrmann 1 and 2) of AS patients compared to HC (NP: 1.88 % ±1.21% vs. 3.38 % ±1.71%; p<0.01; confidence interval (CI): 0.89%/2.11%. AF: 1.11 % ± 1.07 % vs. 1.96 %± 1.23 %; p<0.01; CI 0.39%/1.3%).Conclusion:GagCEST analysis of morphologically non-degenerative IVDs in T2w images showed significantly lower GAG values in patients with AS in the NP and AF compared to HC. Our results potentially allow for the detection of GAG loss prior to morphological degeneration.Figure 1.Comparison of morphological T2 weighted (T2w) images to grade IVD according to the Pfirrmann classification and biochemical imaging with gagCEST between HC (A and C) and AS patients (B and D) showing significant lower GAG levels in AS patients.Disclosure of Interests:Philipp Sewerin Grant/research support from: AbbVie Deutschland GmbH & Co.

Zusammenfassung Ziel Überprüfung von Effekten einer oralen Ergänzung von Mangan (Mn) auf die Mn-Konzentration im Blut laktierender Warmblutstuten und die Untersuchung der Beziehung zwischen der Mn-Versorgung der Mutterstuten und ihrer Saugfohlen. Material und Methoden Für die 90-tägige Fütterungssphase wurden laktierende Stuten in 3 Gruppen eingeteilt und erhielten täglich ein Placebo (n = 11) oder eine Mn-Zulage von 560 mg Mn als Mn-Sulfat (n = 11) oder Mn-Chelat (n = 11) zusätzlich zur Mn-Aufnahme aus der Grundration (Heu ad libitum, Totale Mischration: Mn-Aufnahme ~100 mg/kg Trockenmasse). In 14-tägigen Abständen wurden Blutproben von den Stuten und Fohlen entnommen. Die Mn-Bestimmung im Serum und Vollblut sowie in der Stutenmilch erfolgte mittels Massenspektrometrie mit induktiv gekoppeltem Plasma, die Mn-Analyse in repräsentativen Futterproben mittels Atomabsorptionsspektrometrie. Zur Datenauswertung diente die Software IBM SPSS Statistics 27 (IBM Deutschland GmbH, Ehningen). Ergebnisse Während der Supplementierung zeigten die Stuten im Vollblut (Median: 15,6 µg/l; 25.–75. Perzentil: 12,8–18,5 µg/l) 10-fach höhere Mn-Konzentrationen als im Serum (Median: 1,54 µg/l; 25.–75. Perzentil: 1,20–1,90 µg/l). Die Fohlen wiesen 16,4-fach höhere Mn-Konzentrationen im Vollblut (Median: 21,3 µg/l; 25.–75. Perzentil: 16,7–28,1 µg/l) im Vergleich zum Serum (Median: 1,50 µg/l; 25.–75. Perzentil: 1,30–1,70 µg/l) auf. Die Mn-Vollblutspiegel der Fohlen entsprachen der 1,6-fachen Mn-Konzentration ihrer Mutterstuten. Die Milch enthielt eine mediane Mn-Konzentration von 0,012 mg/kg Frischmasse. Die Mn-Supplementierung hatte keinen Effekt auf die Mn-Spiegel im Blut von Stuten und ihren Fohlen. Schlussfolgerung und klinische Relevanz Die Mn-Supplementierung beeinflusste die Mn-Konzentrationen im Blut nicht, es unterschieden sich aber die Mn-Gehalte zwischen Serum und Vollblut. Ferner lagen die Mn-Spiegel im Vollblut der Fohlen höher als die der Stuten, obwohl die Mn-Konzentrationen – unabhängig von der Supplementierung – in der Stutenmilch niedrig waren. Aufgrund des geringen Mn-Gehalts der Milch ist eine Mn-Zufuhr, vorzugsweise über das Raufutter, notwendig, um die Mn-Versorgung der Fohlen sicherzustellen.

Background:In OA, there is a close association of meniscus and cartilage pathologies. Meniscus degeneration and lesioning are critical risk factors for development of early OA. Hence, thisex-vivostudy assessed the responses to standardized loading of human meniscus samples as a function of degeneration and based on changes in their T1, T2 and T1ρ maps (as surrogate parameters of the tissue’s functionality).Objectives:Can meniscus functionality be visualized by serial quantitative MRI mapping technics?Methods:During total knee replacements, 45 meniscus samples of variable degeneration were harvested from the center of the lateral meniscus body (Fig. 1a1-a3). After preparation to standard, samples were subject to force-controlled loading using an MRI-compatible lever device that created compressive loading by torque ((Fig. 1a4-a5). For each sample and loading position, MRI measurements (as detailed below) were performed in the unloaded (δ0) and loaded configurations, i.e. loaded to 2 bar (δ1, 37.1 N compressive force, 0.67 Nm torque) and to 4 bar (δ2, 69.1 N, 1.24 Nm). Throughout all loading positions, morphological and quantitative imaging was performed using Proton Density-weighted and T1, T1ρ, and T2 mapping sequences (3.0 T, Achieva, Philips) based on standard turbospin-echo, inversion-recovery, spin-lock multi-gradient-echo, and multi-spin-echo sequences. For reference purposes, histological (i.e. Pauli classification) and biomechanical measures (i.e. Elastic Modulus) were obtained for each sample. Based on Pauli sum scores, samples were trichotomized as grossly intact, (n=14), mildly degenerated (n=16), and moderate-to-severely degenerated (n=15).Figure 1.Preparation of meniscus samples and details of the MRI-compatible loading device. The lateral meniscus (a1) was cut to standard size by use of a dedicated cutting block (a2) to eventually obtain lateral meniscus samples (from the body region) of standard dimensions (a3). These samples were then placed in a dedicated MRI-compatible loading device for pressure-controlled, quasi-static and torque-induced loading under simultaneous MR imaging (a4). Two parallel support beams allowed standardized positioning in the MRI scanner‘s bore (a5).Results:Morphologically, loading induced deformation and flattening in all samples (Fig. 2a). For T1, homogeneous loading-induced decreases in all samples were found, irrespective of degeneration (Fig. 2b). For T1ρ, increases in the apical zones of intact samples were observed, and decreases in degenerated samples (Fig. 2c). For T2, changes were ambiguous and incoherent (Fig. 2d).Figure 2.Serial morphological images and functional maps of histologically moderately degenerative human meniscus as a function of force-controlled loading. Serial PDw (a), T1 (b), T1ρ (c), and T2 maps (d) are displayed at increasing loading intensity (δ0: unloaded [a1-d1]; δ1: loaded to 2 bar [a2-d2]; δ2: loaded to 4 bar [a3-d3]). Histologically, this sample demonstrated signs of severe surface desintegration and disruption. Pauli sum score 12, i.e. moderate to severe degeneration (Pauli Grade III). In b – d, color-coded parameter value maps are overlaid onto the corresponding morphological images. Histological sections are stained with Hematoxylin-Eosin (e1) and Safranin O (e2).Conclusion:Meniscus functionality may be visualized using serial quantitative MRI mapping techniques. T1ρ may provide an imaging biomarker of relevant intra-tissue adaptations that seem to be associated with histological degeneration. The perspective evaluation of meniscus functionality may be indicative of incipient or manifest load transmission failure to the adjacent cartilage layer.Disclosure of Interests:Philipp Sewerin Grant/research support from: AbbVie Deutschland GmbH & Co.
