Background:Enthesitis is one of the hallmark of psoriatic arthritis (PsA). Ultrasound (US) accurately detects morphostructural abnormalities indicative of entheseal inflammation and structural damage. Interestingly, in a recent study, US-detected entheseal pathology appeared to be a potential marker of disease severity, being associated with higher radiographic score of structural damage at peripheral joint level. (1) However, a sub-analysis of the impact of each elementary finding of US enthesitis was not performed. Moreover, some US entheseal abnormalities (hypoechogenicity, thickening and calcification/enthesophyte) have been described as frequent findings in healthy subjects and patients with dysmetabolic conditions, undermining their specificity. (2) Thus, we hypothesized that their role as a sonographic biomarker of joint disease severity could be questioned.Objectives:The main aim of the present study was to explore the association between the US elementary findings of enthesitis defined by OMERACT [i.e. hypoechogenicity, thickening, Doppler signal, calcification/enthesophyte and bone erosion at enthesis] (3) and the presence of US-detected joint bone erosions in patients with PsA.Methods:Consecutive patients with PsA (CASPAR criteria) were included in this cross-sectional single-centre study. The scanning protocol included bilateral assessment of the main entheses of the lower limbs [plantar fascia, quadriceps, patellar (proximal and distal) and Achilles tendons]. The presence of US joint bone erosions was investigated in the following areas: 2nd and 5th metacarpophalangeal (MCP) joints, ulnar head and 5th metatarsophalangeal (MTP) joint, bilaterally, as well as the most inflamed joint at the physical examination. The US examination was carried out with a 6-18 MHz probe. Univariate and multivariate logistic analysis were performed to identify predictors of US joint bone erosions.Results:A total of 74 PsA patients were enrolled. The mean disease duration was 7.9±8.0 years. Joint bone erosions were found in 36/75 patients (48.0%), and in 71/600 joints (11.8%), most frequently in the 5th MTP joint (in 26/75 patients, 34.7%). The univariate analysis showed that entheseal bone erosions [odds ratio (OR) 27.1, 95% confidence interval (CI) 3.3-220.2, p value <0.01] and Doppler signal (OR 3.5, 95% CI 1.3 - 9.4, p value 0.01) were associated with joint bone erosions. Only entheseal bone erosions remained significantly associated with joint bone erosions in the multivariate analysis (Table 1).Table 1.Multivariate regression analysis: predictive value of the entheseal US findings for the presence of joint bone erosions.OR (95% CI)P valueHypoechogenicity0.5 (0.1-3.4)0.45Thickening2.2 (0.6-8.3)0.27Doppler signal3.2 (0.9-10.8)0.06Calcification/enthesophyte1.1 (0.1-11.2)0.99Entheseal bone erosion24.2 (2.7-216.2)<0.01Conclusion:Entheseal bone erosion and, to a lesser extent, Doppler signal, were the only entheseal abnormalities correlated with the presence of US-detected joint bone erosions, representing potential sonographic biomarkers of disease severity in PsA.References:[1]Polachek A, Cook R, Chandran V, Gladman DD, Eder L.

Background:Enthesitis is one of the typical pathological signs of spondyloarthritis such as psoriatic arthritis (PsA) and it seems to be the Primum movens of the disease. Clinical assessment of enthesitis showed to be less sensitive, compared to ultrasound (US) evaluation, in identifying enthesitis in patients with PsA [1].OMERACT defined US enthesitis as: “hypoechoic and/or thickened insertion of the tendon close to the bone (within 2 mm from the bony cortex), which exhibits Doppler signal if active and that may show erosions, enthesophytes/calcifications as a sign of structural damage” [3]The reported prevalence of subclinical enthesitis in psoriasis (PsO) patients in different countries ranges between 7% and 20% [2].Objectives:The main objective of this study was to estimate, by US evaluation, the prevalence of subclinical enthesitis in PsO patients without any clinical signs of enthesitis. Secondary objectives were to analyze differences, in terms of age, sex, BMI, PsO onset and diagnosis, among patients with enthesitis (active or not active), enthesopathy and without any alteration of enthesis.According to the OMERACT definition of ultrasound enthesitis, patients were divided into 4 groups: patients with active enthesitis (AE) defined as the presence of power-Doppler signal in a hypoechoic and/or thickened insertion of the tendon close to the bone; patient with enthesitis (En) defined as hypoechoic and/or thickened insertion of the tendon close to the bone without PD signal; patients with enthesopathy (Ep) defined as the presence of structural damage (erosions, enthesophytes/calcifications); patients without any alteration of enthesis (WE).Methods:Patients with at least 18 years and a diagnosis of PsO made by a Dermatologist were included. Exclusion criteria were the presence of clinical symptoms or signs of articular or entheseal involvement, diagnosis of arthritis and therapy with bDMARDs or tsDMARDs.All patients underwent US examination on grey scale and Power Doppler (PD) ultrasonography of 6 sites (Achilles, quadriceps, distal and proximal patellar, plantar fascia and triceps enthesis) bilaterally. Ultrasound was performed by an experienced sonographer, using a Logiq P9 equipped with 6-12 MHz broad band linear transducer. Data were reported as frequencies and median with interquartile range. To check differences among these four groups, we used chi-square test or Kruskall-Wallis test. P-value ≤ 0.05 is considered statistically significant.Results:We enrolled 124 consecutive psoriasis patients (47 [37.9%] female) with median age 57.7 (45.3-66.5) years, median disease duration 20.4 (10.1-30.8) years, median BMI 27 [24-29]. Patients with AE, En, Ep were 20.2% (25/124), 49.2% (61/124) and 18.5% (23/124), respectively.Patients WE (12.1%, 15/124) showed significantly lower BMI, younger age and shorter diagnostic delay compared to the other patients.All signs of enthesopathy/enthesitis were more frequently observed at Achilles (33.1%, 41/124), triceps (23.4%, 29/124), quadriceps (20.2%, 25/124), distal patellar (18.5%, 23/124) and proximal patellar (4.8%, 6/124) enthesis.Conclusion:Subclinical enthesitis is quite common in PsO patients, and about 20% showed active enthesitis. The enthesopathy seems to be more frequent in patients with increased delay in PsO diagnosis, older age and higher BMI.References:[1]Bandinelli F. et al.

Background:Psoriatic arthritis (PsA) is heterogeneous in its clinical presentation and disease course, but many patients (pts) develop a destructive form of arthritis. Psoriasis (PsO) precedes arthritis by an average of 7 years. [1]. Theory of transition from PsO to PsA has been proposed recently [2]. But association between skin disease severity and joint disease are still unclear.Objectives:to evaluate association between bone erosion, PsO duration, skin and nail disease severity in PsA pts based on data from clinical practice (RU-PsART cohort).Methods:737 (M/F=350/387) PsA pts fulfilling the CASPAR criteria were included. Mean age 47.4±12.7 years (yrs), PsA duration 55[17;120] mos., PsO duration 165[74.5;292] mos., mean DAPSA 23.3[14;36.9] mos., HAQ-DI - 0.98 [0.5;1.38], CRP - 7.4 [2.1;18] mg/l. All pts underwent standard clinical examination (tender joins count (TJC)/68, swelling joints count (SJC)/66, CRP (mg/l), DAPSA, dactylitis, enthesitis by LEI + Plantar Facia (PF), HAQ-DI. Mild disease was defined as body surface area (BSA)≤10%, moderate to severe as BSA>10%. The presence/absent of nail PsO was evaluated. X-ray of feet and hand were done in 622 out of 737 pts. The one-factor model of logistic regression was used to identify a group of features that are associated with achievement MDA. M±SD, Me [Q25; Q75], Min-Max, %, t-test, Pierson-χ2, Manna-Whitney tests, ORs with 95% CI were performed. All p<0.05 were considered to indicate statistical significance.Results:PsO precedes of PsA by an average of 9.2 years. BSA≤10% was found in 615 out of 672 pts (91.5%), BSA>10% - in 57 out of 672 pts (8.5%). Nail PsO were seen in 230 out of 737 (31.2%). Bone erosion was found in 237 out of 622 of pts (38.1%). Among these pts nail PsO were seen in 67 out of 237 pts (28.3%). Enthesitis found in 236 out of 737 pts (42.1%), dactylitis – in 197 out 731 pts (27%), axial PsA – in 315 out of 731 pts (43.1%). Bone erosion significantly associated with PsO duration more than 5 yrs., skin and nail PsO severity, high PsA activity by DAPSA, axial manifestation and duration of PsA > 36 mos. (Figure 1).Figure 1Forest plot of factors associated with bone erosion in PsA pts.Conclusion:In our cohort the majority of PsA pts had mild PsO preceded PsA on average of 9.2 yrs. Bone erosion was found in 30% of PsA pts which associated with PsO duration, skin and nail disease severity as well as with PsA activity. Early diagnosis and therapeutic intervention within a “window of opportunity” are very important for improving outcomes and prevent structural damage in PsA.References:[1]Tillett W, et al.

Objective.To confirm the occurrence of bone erosions and synovitis in healthy subjects detectable by ultrasound (US) and to establish US criteria for early arthritis.Methods.Our study involved 127 healthy subjects matched with a cohort of patients with early arthritis (the ESPOIR cohort). The second and fifth metacarpophalangeal (MCP) joints and the fifth metatarsophalangeal (MTP) joint of both hands and feet were assessed with US to detect bone erosion; and the second, third, fourth, and fifth MCP and the fifth MTP were evaluated for synovial thickening in B-mode US and synovial vascularity in power Doppler. Bone erosion and synovitis were defined according to the Outcome Measures in Rheumatology Clinical Trials consensus.Results.Bone erosion and grade 2–3 synovial thickening in B-mode were detected in 11% and 9% of healthy subjects. To consider the diagnosis of early arthritis, a cutoff at 1 case of synovial thickening in B-mode enabled discrimination between patients with early arthritis and healthy subjects, with a good sensitivity of 74.8% (95% CI 67.2%–82.3%) and a high specificity of 90.5% (95% CI 85.4%–95.6%). If higher specificity is required to confirm the diagnosis of early arthritis, cutoff at 2 cases of synovial thickening in B-mode or at 2 cases of bone erosion gave optimal results, with specificity of 98.4% (95% CI 96.2%–100%) and 100%, respectively, and lower sensitivity of 59.8% (95% CI 51.2%–68.3%) and 17% (95% CI 10.5%–23.5%) (area under the curve = 0.85 for synovitis and 0.63 for bone erosion). Neither the combination of power Doppler signal plus bone erosion, nor bone erosions plus synovial thickening on the same joint, were seen in healthy subjects.Conclusion.A single case of bone erosion or synovial thickening in B-mode is common in healthy subjects. However, more than 1 case of synovial thickening in B-mode or bone erosion is a strong argument for the diagnosis of early inflammatory arthritis.

Abstract Adults with atopic dermatitis (AD) have an increased risk for thromboembolic events. While coagulation is critical for almost all healing responses, dysregulated clotting and fibrin(ogen) deposition lead to inflammation that exacerbates tissue damage and impairs tissue repair. While plasma fibrin(ogen) has been associated with established asthma, fibrin(ogen)'s mechanistic role in AD pathogenesis and allergic sensitization has not been investigated. Here we show that fibrinogen plays a critical role in a murine model atopic dermatitis pathogenesis by markedly attenuating disease severity, barrier dysfunction, and allergic sensitization. To determine if fibrinogen impacts AD pathogenesis, we used mice with complete fibrinogen deficiency (Fib -/-), partial deficiency (Fib +/-), and wildtype controls (Fib WT) in our established model of AD. This model uses repeated cutaneous allergen sensitization with heat-killed Aspergillus fumigatus (Asp) extract. Notably, Fib +/- mice produce approximately half as much fibrinogen as Fib WT mice. After each patch and at sacrifice each mouse underwent an objective disease severity assessment as well as transepidermal water loss (TEWL) measurements to assess skin barrier function. Our results show that complete and partial fibrinogen deficiency abrogated AD development. We found that Fib -/-and Fib +/- mice had markedly attenuated TEWL (P-value &lt;0.0001) and disease severity (P-value &lt;0.0001) compared with controls (Figure 1). In addition, we found that the TEWL and disease severity in Fib -/- and Fib +/- were comparable to unchallenged controls. There was also no difference in either outcome between Fib -/- and Fib +/- mice within the experimental group. Lastly, none of the Fib -/- and Fib +/- mice developed spontaneous bleeding. Next, to elucidate the impact of fibrinogen on allergic sensitization we measured plasma allergen specific immunoglobulin E (sIgE) to Asp in all mice in our AD model at sacrifice. We found that Fib -/- and Fib +/- mice had significantly lower Asp sIgE compared with controls (p-value &lt;0.0001 and 0.0002, respectively; Figure 2). In addition, we found that the amount of sIgE to Asp produced was comparable between Fib -/- and Fib +/- mice as well as with unchallenged controls. Thus, our findings suggest that fibrin(ogen) plays a critical mechanistic role in driving AD development and allergic sensitization. While fibrinogen's role in established allergic disease has been shown, these novel findings suggest a critical role for fibrinogen in allergic disease pathogenesis which may allow for additional therapeutic targets to treat atopic dermatitis and other allergic diseases.

Abstract Importance: Since the early days of the pandemic, COVID-19 hospitalizations have been used as a measure of pandemic severity. However, case definitions do not include assessments of disease severity, which may be impacted by prior vaccination.Objective: To measure how the severity of respiratory disease changed among inpatients with documented SARS-CoV-2 infection and to measure the impact of vaccination status on these trends, in order to evaluate the accuracy of the metric of “hospitalization plus a positive SARS-CoV-2 test” for tracking pandemic severity.Design: Retrospective cohort of inpatients with laboratory-confirmed SARS-CoV-2. All data were obtained from electronic health records.Setting: Multi-center, nationwide study conducted in the healthcare system of the US Department of Veterans Affairs (VA) from March 1, 2020, through June 30, 2021.Participants: All VA patients admitted to a VA hospital with a laboratory-confirmed SARS-CoV-2 infection within the 14-days prior to admission or during the hospital admission.Main Outcome: Moderate-to-severe COVID-19 disease, defined by use of any supplemental oxygen or documented SpO2 <94%, during an inpatient hospitalization between one day before and two weeks after a positive SARS-CoV-2 test.Exposure: SARS-CoV-2 vaccination status at the time of hospitalization. Patients were regarded as fully vaccinated starting 14 days after receiving the second of a 2-dose regimen or 14 days after receipt of a single-dose vaccine.Results: Among 47,742 admissions in 38,508 unique patients with laboratory-confirmed SARS-CoV-2, N=28,731 met the criteria for moderate-to-severe COVID-19. The proportion with moderate-to-severe disease prior to widespread vaccine availability was 64.0% (95% CI, 63.1-64.9%) versus 52.0% in the later period (95% CI, 50.9-53.2%), p-value for non-constant effect, <0.001. Disease severity in the vaccine era among hospitalized patients was lower among both unvaccinated (55.0%, 95% CI, 53.7-56.4%) and vaccinated patients (42.6%, 95% CI, 40.6-44.8%).Conclusions and Relevance: The proportion of hospitalizations that are due to severe COVID-19 has changed with vaccine availability, thus, increasing proportions of mild and asymptomatic cases are included in hospitalization reporting metrics. The addition of simple measures of disease severity to the case definition of a SARS-CoV-2 hospitalization is a straightforward and objective change that should improve the value of the metric for tracking SARS-CoV-2 disease burden.

Objective.To assess the performance of various sonographic elemental entheseal lesions in distinguishing between psoriatic arthritis (PsA) and controls to inform the development of a novel sonographic enthesitis score for PsA.Methods.A total of 100 age- and sex-matched individuals (50 PsA and 50 controls) were evaluated. Eleven entheseal sites were scanned bilaterally according to a standardized protocol by 2 sonographers. Based on the Outcome Measures in Rheumatology (OMERACT) definition of sonographic enthesitis, the following lesions were assessed: structural entheseal changes (hypoechogenicity), thickening, bone erosion, enthesophytes, calcification, and Doppler signal, in addition to bursitis and bone irregularities. The images were read by 2 readers blinded to the clinical information. A series of logistic regression models were used to find the optimal combination of entheseal sites and elementary lesions that distinguished PsA from controls.Results.Mean age was 55 ± 10 years (59% males). The optimal model that distinguished PsA from controls included 5 elementary lesions (enthesophytes, Doppler signal, erosions, thickening, and hypoechogenicity) and 6 entheseal sites (patellar ligament insertions into the distal patella and tibial tuberosity, Achilles tendon and plantar fascia insertions into the calcaneus, common extensor tendon insertion into lateral epicondyle, and supraspinatus insertion into the superior facet of the humerus). The area under the receiver-operating characteristic curve for this model was 0.93 (95% CI 0.88–0.98).Conclusion.We identified potential elemental ultrasonographic abnormalities and entheseal sites that could distinguish PsA and controls. This information will contribute to the development of a new sonographic score for assessment of enthesitis in patients with PsA.

The Impact

The impact of the 13-valent pneumococcal conjugate vaccine (PCV13) on overall community-acquired pneumonia (CAP) and disease severity still needs thorough evaluation. In this study, we retrieve both pneumococcal CAP (P-CAP) and unspecific CAP (U-CAP) inpatient data from the Taiwan National Health Insurance Database (NHID) between 2005 and 2016. The interrupted time-series (ITS) analysis was performed to compare the incidence trend before and after the implementation of PCV13. After PCV13 implementation, there is a significant decreasing trend of P-CAP hospitalization, especially in children <1 year, 2–5 years, adults aged 19–65 years, 66 years, or older (all p value < 0.05). This corresponds to a 59% reduction in children <1 year, 47% in children aged 2–5 years, 39% in adult aged 19–65 years, and 41% in elderly aged 66 years or older. The intensive care rate (6.8% to 3.9%), severe pneumonia cases (21.7 to 14.5 episodes per 100,000 children–years), and the need for invasive procedures (4.3% to 2.0%) decreased in children aged 2–5 years (p value < 0.0001) with P-CAP. This PCV13 implementation program in Taiwan not only reduced the incidence of P-CAP, but also attenuated disease severity, especially in children aged 2–5 years.

ObjectivesTo evaluate the reliability of consensus-based ultrasound (US) definitions of elementary components of enthesitis in spondyloarthritis (SpA) and psoriatic arthritis (PsA) and to evaluate which of them had the highest contribution to defining and scoring enthesitis.MethodsEleven sonographers evaluated 40 entheses from five patients with SpA/PsA at four bilateral sites. Nine US elementary lesions were binary-scored: hypoechogenicity, thickened insertion, enthesophytes, calcifications, erosions, bone irregularities, bursitis and Doppler signal inside and around enthesis. Kappa statistics were used to evaluate reliability. Sonographers were also asked to state which lesions can be considered as inflammatory or structural and should be included in the final definition of enthesitis. Only the lesions, scored as present in at least 75% of the entheses considered as having an enthesitis, were included in the final definition.ResultsThe prevalence of detected lesions was quite low except for enthesophytes (55%) and bone irregularities (54%). Reliability ranged from poor to good (the lowest for thickened enthesis (kappa 0.1 (95% CI 0 to 0.7)) and the highest for enthesophytes (kappa 0.6 (95% CI 0.5 to 0.7)). When adjusted for low prevalence, kappa values increased for all lesions, with the best result observed for detecting Doppler signal at insertion (0.9) and for bursitis (0.8). The US components included in the final definition were hypoechogenicity, increased thickness at enthesis, erosions and calcifications/enthesophytes and Doppler signal at insertion.ConclusionBy using a consensus-based stepwise approach, a final reliable US score and definition of enthesitis in SpA/PsA were produced. Further studies are sought for implementing this score in clinical trials and practice.

Abstract Background Although the short-term effects of tumor necrosis factor alpha (TNF-α) and interleukin-17A (IL-17A) inhibition on the structural changes in psoriatic arthritis (PsA) using high-resolution peripheral quantitative computed tomography (HR-pQCT) have been reported, no studies have investigated the long-term structural changes in PsA patients receiving routine care. We reported longitudinal changes of erosions and enthesiophytes using HR-pQCT and their relationship with treatments in PsA patients over a 5-year period. Methods HR-pQCT examination at the second and third metacarpal heads (MCH2 and MCH3) was performed in 60 PsA patients at baseline and after 5 years. The size of each individual lesion was quantified. Erosion and enthesiophyte progression were defined as change exceeding the smallest detectable change (SDC). Results A total of 108 bone erosions and 99 enthesiophytes were detected at baseline. Three new bone erosions but no new enthesiophytes were evident at 5 years. A significant increase in mean (±SD) erosion (0.58 ± 1.50 mm3, P < 0.001) and enthesiophyte (0.47 ± 0.76 mm3, P < 0.001) volume was observed. Erosion and enthesiophyte progression were found in 37/111 (33.3%) and 50/99 (50.5%) lesions, respectively. During this 5-year period, 26 (43%) out of the 60 patients achieved sustained Disease Activity index for PSoriatic Arthritis (DAPSA) low disease activity (LDA) (SDL group, defined as achieving DAPSA-LDA at both baseline and 5 years). Fourteen (23%) out of 60 patients received a TNF inhibitor throughout the 5-year period (TNFi group). Fewer erosions progressed (12/51 [23.5%] vs 25/60 [41.7%], P = 0.047) and the increased in enthesiophyte volume was significantly less (0.28 ± 0.67 vs 0.61 ± 0.80 mm3, P = 0.048) in the SDL group than in the non-SDL group. However, no significant difference between the TNFi and non-TNFi groups was detected in terms of the change in volume or progression of bone erosion and enthesiophyte. Conclusion Damage accrual in terms of bone erosion and enthesiophyte was observed in PsA patients over a period of 5 years despite receiving routine clinical care. Nonetheless, sustained control of disease activity may be able to prevent these bony damages.
