Background:Achilles enthesitis is the most accessible psoriatic arthritis hallmark to assess through ultrasound scan. Recently it has been demonstrated that continuous mechanical stress such as experimented by runners can drive to the development of physiological morphological changes that resembles those observed in psoriatic arthritis. In a subject with the suspicious diagnostic of psoriatic arthritis who practice any sports associated to continuous impact over the heels, the challenge to determine in what extent the morphological changes are linked to the exercise or to the disease, is remarkable.Objectives:To determine morphological differences between patients with psoriatic arthritis, trained runners and sedentary volunteers through ultrasound scan of the Achilles tendon.Methods:An ultrasound scan of the Achilles tendon was performed to the following subjects: Patients with diagnosis of psoriatic arthritis with a DAPSA score of low activity in at least six months and with history of heel pain in the past, volunteers runners with not less of 3-year sport activity at least three times a week and sedentary volunteers. In the group of patients, ultrasound scan was performed over the feet with history of heel pain. In the case of volunteers, the ultrasound scan was performed in the dominant feet. The selection of volunteers was not randomly-based in order to match their age and sex to the patients as much as possible. Besides demographic features, a comparison between tendon thickness at the level of the calcaneus bone border and the height of the retrocalcaneus bursae in the longitudinal axis were performed through ANOVA test. Power Doppler signal was scaned in all subjects before and after a controlled mechanical stress of the Achilles tendon by climbing stairs (100 steps, two times).Results:Female/male distribution of the group of patients, runners and sedentary people were: 12/10, 18/18 and 20/18, respectively. Achilles tendon mean thickness ± standard deviation was 6.61 ± 1.05, 5.91 ± 1.44 and 4.61 ± 2.1mm, respectively (P=0.01). Retrocalcaneus bursae height was 3.42 ± 0.21, 3.22 ± 0.27 and 2.21 ± 0.31 (P=0.01). Basal PD signal was present into the enthesis of 2/22, 1/36 and 0/38, respectively (P not significant). After exercise, PD signal was present in 8/22, 5/36 and 0/38, respectively (P<0.001).Conclusion:Power Doppler signal after exercise was identified as the most relevant ultrasound hallmark to distinguish a patient with psoriatic arthritis from a trained runner, even when psoriatic arthritis were considered as low activity. Post exercise ultrasound scan should be considered as a diagnosis tool in sportsmen with suspicious of psoriatic arthritis, until further studies confirm our findings.Disclosure of Interests:None declared

Objective. To compare scores for the Leeds enthesitis index in psoriatic arthritis and rheumatoid arthritis using clinical assessment and ultrasonography (US). Design. Swelling and tenderness of the enthesis was assessed at six sites: lateral epicondyles of humerus (LE), medial condyles of femur (MC), and the insertion of the Achilles tendon (AT). US assessed “inflammatory activity” (power Doppler signal, oedema, tendon thickening, and bursal swelling) and “damage” (erosions and enthesophytes). Results. 94 patients were included, 71 with PsA and 23 with RA. The patients with RA were significantly older (PsA 47.6 years; RA 62.6 years; (mean difference in ages =15.0 years, 95% CI 9.3–20.7 years)). US scores were higher in RA at the LE, significantly so for the “damage” scores. No differences between RA and PsA were seen at the other sites. As a result, the odds ratio for PsA, given an US score above the median, was 0.41 (0.13–1.03). However, using the clinical score, the odds ratio for PsA was 2.16 (0.81–5.70). Conclusions. Although clinical scores of enthesitis are greater in PsA compared to RA, US enthesitis scores did not distinguish between RA and PsA. This may in part be due to more frequent juxta-articular involvement in RA and in part due to the older age of the subjects with RA.

Background:Preclinical models have indicated that biomechanical stress can trigger entheseal inflammation (1). Furthermore, enthesitis is a hallmark of psoriatic arthritis (PsA) and spondyloarthritis (SpA), suggesting that mechanoinflammation is an important step in their pathogenesis (2). However, the relation between mechanical stress and enthesitis in humans is poorly investigated. Competitive badminton is a demanding stop-and-go sport that strains entheseal sites in particular and provides an opportunity to assess the impact of physical activity on the development of an instant inflammatory response in the entheses.Objectives:To evaluate the influence of mechanical stress on the development of immediate enthesitis.Methods:BEAT (Badminton Enthesitis Arthrosonography Study) is an interventional study that assessed entheses in competitive badminton players before and immediately after a 60-minute intensive training session by ultrasound. Power Doppler (PD) signal and Gray-Scale (GS) changes were evaluated at the insertions sites of both Achilles tendon, patellar tendons and lateral humeral epicondyles and quantified using a validated scoring system (3). Pre- and post-training scores were compared using linear mixed-effects models. We used interaction terms to assess possible differential effects on patellar, elbow and Achilles entheses.Results:Thirty-two badminton players (22 men, 10 women) with an average age of 31.1±13.0 years were included (Table 1). On average, they had been playing badminton for 16.2±10.1 years. 192 entheseal sites were examined twice. The respective empirical total scores for PD examination were 0.1 (0.3) before and 0.5 (0.9) after training (Figure 1). Mean total GS scores were 2.9 (2.5) and 3.1 (2.5) before and after training, respectively. The mean total PD score difference of 0.4 between pre- and post -training was significant with a p value of 0.0014, whereas the p value for the mean total GS score difference of 0.2 was 0.63. Overall, seven participants (22%) showed an increased empirical total PD score. A mixed-effects model showed a significant increase of PD scores after training, with a mean increase per site of 0.06 (95%CI 0.01 to 0.12, p=0.017).Table 1.Baseline characteristicsDemographic characteristicsN, total32Females, N (%)10 (31.3)Age, years (mean ± SD)36.1 ± 13.0Height, cm (mean value ± SD)178.6 ± 9.9Body weight, kg (mean value ± SD)74.7 ± 13.5Smoking, N (%)11 (34.4)Alcohol, N (%)24 (75.0)Concomitant DiseasesInflammatory bowel disease, N (%)0Psoriasis, N (%) 0Uveitis, N (%)0Diabetes mellitus, N (%)0Hypertension, N (%)2 (6.3)Sports historyYears Badminton (mean ± SD)16.2 ± 10.1Figure 1.Ultrasound scores before and after training Figure 1.

These data support the concept of mechanoinflammation in diseases associated with enthesitis. However, while such responses may be self-contained in healthy subjects, they may be prolonged and more pronounced in certain risk groups, such as patients with PsA or SpA.References:[1]Cambré I, et al.

Objective.To investigate the frequency and distribution of characteristics of the Achilles tendon (AT) in people with tophaceous gout using musculoskeletal ultrasound (US).Methods.Twenty-four participants with tophaceous gout and 24 age- and sex-matched controls without gout or other arthritis were recruited. All participants underwent a greyscale and power Doppler US examination. The AT was divided into 3 anatomical zones (insertion, pre-insertional, and proximal to the mid-section). The following US characteristics were assessed: tophus, tendon echogenicity, tendon vascularity, tendon morphology, entheseal characteristics, bursal morphology, and calcaneal bone profile.Results.The majority of the participants with tophaceous gout were middle-aged men (n = 22, 92%) predominately of European ethnicity (n = 14, 58%). Tophus deposition was observed in 73% (n = 35) of tendons in those with gout and in none of the controls (p < 0.01). Intratendinous hyperechoic spots (p < 0.01) and intratendinous power Doppler signal (p < 0.01) were more frequent in participants with gout compared to controls. High prevalence of entheseal calcifications, calcaneal bone cortex irregularities, and calcaneal enthesophytes were observed in both gout participants and controls, without differences between groups. Intratendinous structural damage was rare. Hyperechoic spots were significantly more common at the insertion compared to the zone proximal to the mid-section (p < 0.01), but between-zone differences were not observed for other features.Conclusion.US features of urate deposition, tophus, and vascularization are present throughout the AT in patients with tophaceous gout. Despite crystal deposition, intratendinous structural changes are infrequent. Many characteristics observed in the AT in people with tophaceous gout, particularly at the calcaneal enthesis, are not disease-specific.

Background:Detection of subclinical enthesitis and synovitis in psoriatic arthritis (PsA) is prevalent and ultrasound (US) examination is informative tool for it diagnosing. Aging positively affects degenerative changes.Objectives:To study relationship between US articular and entheseal findings with age in patients with PsA.Methods:57 patients were enrolled to study with fulfilled PsA criteria (CASPAR, 2009). Data collection: demographical, clinical (current psoriasis, axial involvement, enthesitis, dactylitis), US (synovitis count (by Grey Scale), Power Doppler(PD)+ synovitis), thickening and hypoechogenicity at enthesis, PD+ enthesitis, entheses with structural components); biological (high sensitive C-reactive protein (hsCRP), Erythrocyte Sedimentation Rate (ESR).US examination included 798 joints and 3078 entheses (bilateral shoulders, acromioclavicular joints, elbows, wrists, hips, knees, ankles; entheses at the projection of these joints (total number - 54). US entheseal findings were fixed according to consensus-based US definition and scoring for enthesitis in spondyloarthritis and PsA (OMERACT US)1.Results:In all 57 patients: male - 25 (43.9%), mean age 43.4±10.3(SD) years (y), PsA duration was 7 (3;10) y, Ps duration 10 (8; 22) y; 53 (41.1%) had axial involvement, 42 (73.7%) dactylitis, 8 (14%) clinical enthesitis, and 56 (98.2 %) skin psoriasis, Psoriasis Activity and Severity Index score 6.4 (2;14.4), Disease Activity in PsA score 18.1 (10.2;26.1), hsCRP 10.1(2.4;21.4), ESR 20 (11.3;31.5).Synovitis count increased with age noticeably (r=0.508, p<0.01), and weak correlation of PD+ synovitis (r=0.262, p=0.049) and age was found. The entheseal thickening and hypoechogenicity and structural findings increased with age respectively (r=0.345, p=0.009; r=0.337, p=0.01). There was no correlation between PD+ enthesitis and age. The assosiation between PD+ enthesitis and blood biomarkers of inflammation (hs-CRP (r=0.364, p=0.008); ESR (p=0.358, p=0.008) was found.Conclusion:Our study found significant relationship between age and US synovitis. Association between age and US entheseal involvement was noted. Only PD+ enthesitis was not related with age in comparison with other US entheseal findings. The presence of PD US signal at enthesitis in association with increased inflammatory blood biomarkers can be evaluated as the sign of disease activity regardless of age and not as age-related lesion in PsA patients.References:[1]Balint PV, Terslev L, Aegerter P et al.

Background:Psoriatic arthritis (PsA) is a heterogeneous disease and its assessment is sometimes difficult. Perception of disease activity by patient and physician is frequently discordant in patients in clinical remission. Ultrasound (US) is an imaging technique, which can detect inflammation in PsA.Objectives:The aim of our study was to assess whether persistence of disease activity evaluated by the patient, considered in remission by his rheumatologist, was associated with inflammation measured by US.Methods:We performed a transversal monocentric study. PsA patients were included if they met the CASPAR criteria and were considered in remission by their rheumatologist. Demographic data, characteristics of the disease and treatments were collected. Discordance was defined by a difference between patient’s and rheumatologist’s global assessment ≥30/100 on a Visual Analogic Scale. An US examination was performed on 50 joints, 28 tendons and 14 entheses by an independent investigator. Synovial or tendon sheath hypertrophy and PD signal were evaluated on a semi-quantitative scale, B Mode and PD signal abnormalities on entheses were searched, according to the EULAR-OMERACT scoring system. US remission was defined by no power Doppler (PD) signal on joints, tendons and entheses and minimal US activity by maximum one PD signal on the same sites. Univariate and multivariate analyses were performed to evaluate factors associated with US abnormalities.Results:Sixty-two PsA patients were included. 40.3% were women, the mean (SD) age was 55 (14) years, 42% were in US remission and 71% in minimal US activity (Table 1), 19.4% had ≥1 PD synovitis and 88.7% had a B mode synovitis, 95.2% had a B mode abnormality on entheses and 51.6% had ≥1 PD signal on entheses. Thirty nine percent had a discordant disease activity assessment with their rheumatologist. In univariate analysis, discordance was not associated with US remission (OR=1.71 (95%CI 0.61-4.83), p=0.224) or US minimal disease activity (OR=0.99 (95%CI 0.32-3.05), p=0.602). In multivariate analysis, US remission was independently associated with female gender (OR=3.94 (95%CI 1.20-12.9), p=0.024) and younger age (OR=0.95 (95%CI 0.91-0.99), p=0.027). Minimal US activity was associated with history of enthesis lesion (OR=11.26 (95%CI 1.34-94.93), p=0.026) and age (OR=0.95 (95%CI 0.90-1), p=0.044).Table 1.Ultrasound characteristics of the 62 PsA patients.N (%)Ultrasound remission26 (41.9)Ultrasound minimal disease activity44 (71)Patients with ≥1 grey scale synovitis55 (88.7)Patients with ≥1 Power Doppler synovitis12 (19.4)Patients with ≥1 grey scale tenosynovitis15 (24.2)Patients with ≥1 Power Doppler tenosynovitis1 (1.6)Patients with ≥1 grey scale enthesitis lesion (thickness, hypo echogenicity, calcification, enthesophyte, erosion, bursitis)59 (95.2)Patients with ≥1 Power Doppler enthesitis32 (51.6)Conclusion:Our study showed persistent inflammation evaluated by US in PsA patients considered in remission by their rheumatologist.

Background:In patients with spondyloarthritis (SpA), root joint diseases (RJD), i.e. hip or shoulder involvement, may be associated with a distinct disease phenotype compared to those with other affected joints. The ASAS-PerSpA study (PERipheral involvement in SPondyloArthritis) [1], offers a unique opportunity to study the phenotypes of patients with RJD in a global cohort.Objectives:Primary objective was to compare the clinical characteristics of SpA patients with and without RJD. Secondary objectives were to compare the prevalence of RJD across the different SpA subtypes and the different regions of the world, compare the severity of axial disease as well as the disease burden in SpA patients with and without RJD.Methods:This is a post-hoc analysis of the ASAS-PerSpA study, which included 4,465 patients with any subtype of SpA (axial SpA (axSpA), peripheral SpA (pSpA), psoriatic arthritis (PsA), inflammatory bowel disease associated SpA (IBD-SpA), reactive arthritis (ReA) and Juvenile SpA (Juv-SpA)) according to the rheumatologist’s diagnosis. RJD was defined as a positive answer by the investigator to the following question: “Do you consider that the patient has ever suffered from RJD (e.g. hip, shoulder) related to SpA?” In case of a positive answer, a potential specific treatment (e.g. Total Articular Replacement) was investigated. The patient’s characteristics were compared between those with and without RJD involvement, using Chi-2 or Fisher exact test for the categorical variables and t-test for the continuous variables. Two separate multivariable stepwise binary logistic regression analyses were conducted to identify factors associated with the dependent variables “hip involvement” and “shoulder involvement”.Results:RJD occurred in 1,503 patients (33.7%), with more prevalent hip (24.2%) than shoulder (13.2%) involvement. The prevalence of RJD as a group was the highest in Juv-SpA (52.7%), followed by pSpA (44.3%) and axSpA (33.9%). The highest prevalence of RJD was found in Asia and the lowest in Europe and North America. Among patients with hip involvement, 6.0% had a history of hip replacement (highest in the Middle East and North Africa and Latin America); among patients with shoulder involvement, 0.8% had a history of shoulder replacement. Hip had a distinct pattern of associations compared to shoulder involvement (Figure 1). Hip involvement was significantly associated with the SpA main diagnosis (highest in pSpA, lowest in PsA), younger age at first SpA symptom, lower prevalence of family history of psoriasis, positive HLA-B27, occiput-to-wall distance>0, and treatment with cs-DMARDs and b-DMARDs. Shoulder involvement was associated with the SpA main diagnosis (highest in Juv-SpA and pSpA, lowest in axSpA), older age at first SpA symptom, higher prevalence of enthesitis, dactylitis, tender joints count, IBD, occiput-to-wall distance>0, EQ5D score and treatment with cs-DMARDs.Conclusion:Hip involvement was more prevalent than shoulder involvement in patients with SpA, and had a distinct phenotype resembling axial disease whereas shoulder involvement was mostly associated with features of peripheral disease. Hip and shoulder involvement should be analyzed separately in future studies rather than under the RJD entity.References:[1]Lopez-medina, C. et al.

Background:Together with autoimmune-inflammation and fibrosis, microvasculopathy is a hallmark of SSc. However, also macrovascular changes may occur including peripheral proliferative vasculopathy. Whether this changes may represent a specific SSc marker with a predictive value remains a matter of debate.[1,2,3]Objectives:To study peripheral macrovascular involvement by color doppler ultrasound (CDUS) with spectral wave analysis (SWA) in a cohort of 40 SSc patients as compared to healthy controls. To further analyze any differences among the SSc population.Methods:Forty SSc patients and 36 healthy controls were examined by CDUS with SWA of both hands. Macrovascular involvement was assessed by measuring the resistivity index (RI) of distal ulnar and radial arteries. Examinations were performed with an Esaote MyLab Twice machine equipped with a linear 10-22 MHz probe. Ultrasound examination was carried out by two independent rheumatologists blinded to clinical conditions of the patients. Statistical analysis was performed by using MaxStat software.Results:The RI index resulted increased in the SSc cohort as compared with healthy controls (left ulnar RI 0.977 vs 0.715; right ulnar RI 0.996 vs 0.699; left radial RI 0.988 vs 0.706; right radial RI 0.999 vs 0.688; p<0.001). SSc patients with an increased RI in one artery were more probable to have an increased RI in the other vessels too (r 2 = 0.35; p<0.01). In addition, 8 out of 40 SSc patients presented left ulnar artery occlusion (UAO) and 7 out of 40 SSc patients presented right UAO, of which 6 presented bilateral UAO. Awaiting to enlarge the cohort for further analysis, descriptive data regarding increased RI at CDUS/SWA and clinical features, including years from onset of the disease, subtype of SSc, mRSS, history of digital ulcers, interstitial lung disease and PAH are described in Table 1.Conclusion:Peripheral macrovascular involvement was observed in SSc patients as compared with healthy controls. Further studies will determine whether this feature may have specificity for diagnosis/prognosis in SSc.References:[1]Lescoat A, Yelnik CM, Coiffier G et al.

Background:Entheseal involvement is a frequent and distinctive feature of psoriatic arthritis (PsA), often under diagnosed. It is especially associated with nail involvement. Because clinical examination is not sensitive enough for the detection of early signs of this involvement, US may be considered as an alternative imaging technique in the diagnosis of enthesopathy.Objectives:The aim of the present study is to evaluate US entheses abnormalities in PsA and their correlation with clinical characteristicsMethods:The study included patients diagnosed with PsA according to the CASPAR criteria. They underwent a thorough clinical examination with special regard to the presence of enthesitis using the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index.The US study bilaterally explored entheses at six sites: proximal plantar fascia, distal Achilles tendon, distal and proximal patellar tendon insertion, distal quadriceps tendon and distal brachial triceps tendon. We evaluated the following elemental lesions of enthesis at each site: thickness and structure of the tendon, calcifications, bursae, erosions, power Doppler signal in bursa or enthesis full tendon.Results:Of the 33 patients, 39.4 % were male. The mean age was 51.2±12.5 years. The mean disease duration was 13.5±10.2 years.The mean DAPSA was 22.8± 19.7 [0.1-84.5]: remission(n=9), low activity (n=5),moderate activity (n=11),high activity(n=8).At inclusion, 11 patients (33.4%) patients presented with psoriatic onychopathy (45 fingernails) with a mean mNAPSI of 14.1±16. Out of the 528 entheseal sites, 92 were tender at the palpation (17,4%) with a mean SPARCC at 2.87.A total of 396 entheseal sites were examined by US. In 140 of them (35.35%), US found at least 1 sign indicative of enthesopathy. The most affected tendon was the distal Achilles tendon (42/396), followed by proximal plantar fascia (32/396), distal patellar tendon (20/396), quadriceps tendon (20/396), distal brachial triceps tendon(14/396) and finally proximal patellar tendon (12/396).The most common elemental lesions were enthsophytes (176), erosions (114) and calcifications (50).We found a positive correlation between age and both calcification (r=0,4, p=0.021) and enthesophytes (r=0.479, p=0.005).We found a positive correlation between enthesophyte and the tender and swollen joints count (r= 0.352, p=0.045, r=0.378, p=0.03) and the SPARCC score (r=0.397, p=0.022).Patients with higher BASDAI had thicker tendons (r=0.355, p=0.05).Patients with nail dystrophy had more bursitis and erosions.US scores did not correlate with sexe, disease duration and disease activity measures (ASDAS, DAPSA, DAS28 and PASI). Patients with subclinical entheseal involvement didn’t have higher inflammatory biomarkers (ESR, CRP).Conclusion:US subclinical enthesopthy are not rare in psoriatic arthritis, in particular in patients with active disease.Clinical nail involvement was associated with bursitis and erosions. New studies including larger study groups are required to verify the findings of the present studyDisclosure of Interests:None declared

Background:TNF inhibitors have been largely demonstrated to be effective and reasonably safe for the treatment of psoriatic arthritis (PsA). Current EULAR guidelines recommend the use of an anti-TNF as first choice treatment in patients with PsA for whom a synthetic DMARD (usually methotrexate or leflunomide) is not efficacious or not well tolerated [1]. In a scenario where biologic treatments are easily available, and the treat to target strategy is widely accepted, a complete disease remission or at least a minimal disease activity are considered realistic goals to be achieved in a growing proportion of patients [2]. However, there remains very little research regarding anti-TNF discontinuation in patients who achieved a complete remission [3-5].Objectives:The primary aim of this study was to measure the disease-free interval after anti-TNF discontinuation, secondary it was investigated whether the use of Power Doppler Ultrasound (PDUS) and Contrast Enhanced Ultrasound (CEUS) could improve the diagnostic accuracy in the recognition of the relapse. Finally, we wanted to characterize the clinical features of the disease recurrence.Methods:From June 2018, 35 patients with PsA (27 males and 8 female) treated with anti-TNF, in stable remission were prospectively monitored for 1 year after treatment discontinuation. Remission was defined as documented absence of clinical and ultrasonographic signs of arthritis or enthesitis. Complete rheumatological and dermatological examinations were performed in all participants, at baseline and every 8-12 weeks: American College of Rheumatology (ACR) 66-68 joint count; Psoriasis Area Severity Index (PASI); patient pain visual analog score (VAS); patient global disease activity VAS; Health Assessment Questionnaire (HAQ); Leeds Enthesitis Index (LEI); Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); Bath Ankylosing Spondylitis Functional Index (BASFI); Power Doppler Ultrasound (PDUS) of the involved joints and entheses, Contrast Enhanced Ultrasound (CEUS) of a selected joint or enthesis and laboratory inflammation tests.Results:31 out of the 35 enrolled patients, experienced a disease recurrence with an average disease-free interval of 27.9±21.1 weeks (Figure 1). In 3 patients the treatment was restored for a relapse of the skin psoriasis, 8 patients reported only axial symptoms of disease relapse and 20 patients had both axial and peripheral joints involvement (average DAPSA score of 23.6±11.1; average BASDAI score of 4.7±2.6; average BASFI score 4.5±2.9). In all cases the disease flare was moderate and all patients promptly regained remission after restarting the treatment. Both PDUS and CEUS were safe and reliable showing a good percentage of accordance (95,4%) in detecting synovitis and enthesitis.Conclusion:The rate of disease relapse of PsA after anti-TNF discontinuation is relevant. However the disease-free interval was not short. Retreatment with the same anti-TNF was effective and safe.References:[1]Gossec L, Baraliakos X, Kerschbaumer A, et al.

Although the etiology of chronic rhinosinusitis remains unknown, environmental factors including airborne pollutants and toxicants are postulated to contribute to its pathogenesis. However, the precise pathomechanisms with which environmental toxicants may contribute to chronic rhinosinusitis are not fully understood. The purpose of this pilot study is to examine the cytotoxic effects of N,N-diethyl- meta-toluamide (DEET), a commonly used pesticide, on sinonasal epithelial cells (SNECs). Sinus mucosa was obtained from 3 subjects without a history of chronic rhinosinusitis. Cultured SNECs were exposed to various concentrations of DEET (0-5 mM) for 6 days. Cell viability, proliferation, and morphologic changes were assessed using the MTT colorimetric dye assay and the Incucyte Live Cell Monitoring System. Statistically significant dose-dependent reduction in cell viability and proliferation was observed between exposure and control groups ( P < .05) at all concentrations tested. Dose-dependent cellular morphological changes were also seen. These findings indicate that DEET exposure induces dose-dependent cytotoxicity in sinonasal epithelia.
