Abstract
BACKGROUND G-EPOSS is a prospective, non-interventional, German multicentre study of patients with moderate-to-severe plaque psoriasis receiving guselkumab, a therapeutic monoclonal antibody targeting interleukin-23, in a real-world setting. OBJECTIVES The objective of the study was to evaluate the effectiveness and safety of guselkumab, including its impact on skin, health-related quality of life (HRQoL), sexuality, and perceived stigmatization. METHODS Patients (≥18 years old) received guselkumab per routine clinical practice. The primary endpoint was the proportion of patients achieving absolute Psoriasis Area and Severity Index (PASI) ≤ 3 at Week (W)28. Secondary endpoint assessments over 28 weeks included the Nail Psoriasis Severity Index (NAPSI), anogenital Physician's Global Assessment (aPGA), and Dermatology Life Quality Index (DLQI). Sexuality and perceived stigmatization were assessed by patients using the Relationship and Sexuality Scale (RSS) and Perceived Stigmatization Questionnaire (PSQ), respectively. RESULTS Overall, 293 patients were included in the evaluable set population. Mean age and disease duration were 45.6 and 17.6 years, respectively. At baseline, mean PASI, aPGA and DLQI scores were 15.3, 2.7 and 11.3, respectively. In total, 25.9% of patients had received a prior biologic. Overall, 83.0% of patients achieved PASI ≤ 3, and 56.2%/35.1% achieved PASI ≤ 1/PASI = 0, respectively, at W28. Among those with NAPSI ≥ 1 and aPGA ≥ 1 at baseline, NAPSI = 0 and aPGA = 0 were achieved by 39.2% and 61.1% of patients, respectively, and 61.4% of patients achieved DLQI 0-1 at W28. Improvements were observed over 28 weeks across individual items of the DLQI, RSS and PSQ, indicating improved HRQoL and sex life, and decreased perceived stigmatization. Based on DLQI Question (Q)9, 53.6% of patients experienced sexual difficulties at baseline, which decreased to 12.1% at W28. DLQI Q9 responses were consistent with RSS item responses, highlighting DLQI Q9 as a sentinel for sexual impairment. CONCLUSIONS Guselkumab improved overall skin symptoms and HRQoL in patients with psoriasis and decreased sexual impairment and perceived stigmatization. No new safety signals were observed.

Abstract
BACKGROUND Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs. METHODS The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe. RESULTS SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life. CONCLUSIONS We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is characterized by chronic, systemic inflammation, organ damage and -dysfunction. Autonomic nervous system dysfunction is highly prevalent in SLE patients (up to 54%); compared to controls the prevalence may be up to 12 times increased.1 These numbers parallel findings in other chronic conditions such as diabetes.2Heart rate variability (HRV) reflects autonomic activity, and low variability indicates impaired activity, denoted as autonomic dysfunction (AD). AD is associated with low-grade inflammation in healthy subjects and patients with diabetes or cardiovascular disease.3 The causality hereof is not fully understood: AD may impair the vagally mediated anti-inflammatory reflex, thus leading to increased systemic inflammation, but inflammatory mediated microvascular and neuronal damage may also impair autonomic function.ObjectivesTo determine if markers of low-grade inflammation are associated with AD in SLE patients.MethodsSLE patients (n=111) from the Copenhagen based PLUSheart (Prospective Lupus Study on Cardiovascular Risk Factors) cohort were included for this cross-sectional analysis. The cohort has previously been described1 with the following characteristics in 2018-2019: 89.2% women, mean age: 51.5 (SD ±12.7) years, mean BMI: 25.1 (±5.0), mean disease duration: 19.9 (±9.5) years, median SLEDAI 2K score: 3 (IQR 1-4), and median SLE Damage Index score: 2 (1-4).Low-grade inflammation was evaluated by plasma levels of C-reactive protein (CRP) and soluble urokinase-type plasminogen activator receptor (suPAR). Autonomic function was assessed with 5-min resting lead-I electrocardiograms using the VagusTM device. Subsequent HRV analyses comprised RMSSD (the root mean square of successive interval differences between normal heartbeats), reflecting parasympathetic function, and SDNN (standard deviation of normal-to-normal heartbeat intervals), reflecting mixed parasympathetic-sympathetic function.ResultsAll HRV- and inflammatory markers were non-normally distributed. The median SDNN was 30.4 (IQR 24.1-40.4), the median RMSSD was 19.7 (12.6-31.7). The median CRP level was 1 (1-3) and suPAR level was 3.2 (2.5-4.6).For parametric analyses, all markers were logarithmically transformed. Both SDNN and RMSSD associated with CRP and suPAR levels in univariate analyses. When adjusting for age and SLE disease activity as per the SLEDAI-score, SDNN remained associated with suPAR and CRP and RMSSD with suPAR only (Table 1).Table 1.Association between low-grade inflammation and autonomic nervous system functionSDNN *RMSSD *UnivariateAdjustedUnivariateAdjustedβPβPβPβPCRP *-0.2410.011-0.1970.035-0.2150.024-0.1680.072suPAR *-0.2390.014-0.1970.038-0.2680.006-0.2270.016Univariate and multivariate linear regression analyses adjusted for age and disease activity of correlations between log-transformed (*) low-grade inflammation markers (CRP and suPAR) and heart rate variability markers (RMSSD and SDNN). β=standardized coefficients.

Abstract
BackgroundNephritis (LN) in systemic lupus erythematosus (SLE) is still a major determinant of poor prognosis[1].The vast majority of LN occurs in proximity to the SLE diagnosis[2]. Identification of individuals at high risk, especially early onset SLE, is therefore warranted. Inclusion of risk factors prior to the SLE diagnosis may thus be of importance to enable sufficient risk factor profiling. SLE-patients seem to cluster according to clinical and serological phenotypes suggesting distinct disease trajectories[3-5].ObjectivesTo determine if incident proteinuria associated with the debut age of non-renal SLE characteristics.MethodsData of SLE patients from six Danish centers were obtained from the Danbio-database from 2017 – 2020. The occurrence and timing of proteinuria was compared with first time onset of any non-renal manifestations as defined by the 1997 American College of Rheumatology Classification Criteria. Cox-regression models were used to identify risk factors for incident proteinuria. Time from first occurring non-renal manifestation to incident proteinuria or censoring defined time at risk. Covariates were eliminated if p >0.01 in a ‘backwards’ manner. After the model reduction process p-values <0.05 were considered statistically significant.Results586 SLE patients, mainly white (94%) women (88%), mean age at inclusion of 34.6 years (standard deviation, SD = 0.6 years) and observed for a mean of 14.9 years (SD =0.5 years), were recruited. The cumulative prevalence of proteinuria was 40%. Male gender hazard ratio, HR = 1.35 (range 0.77-2.35), p=0.009, lymphopenia HR = 1.77 (range 1.24-2.52), p=0.005 were associated with incident proteinuria. In contrast, patients with discoid rash had lower risk of incident proteinuria HR 0.42 (range 0.21-0.83), p=0.01. Male patients with lymphopenia had the highest risk of proteinuria with a one-, 5- and 10-year risk of proteinuria ranging from 9-27%, 34-75% and 51-89 %, depending on the age at presentation (debut at 20, 30, 40 or 50 years). The corresponding risk-profiles for women with lymphopenia were 3-9%, 8-34% and 12-58%, respectively, as illustrated in Figure 1.ConclusionThe occurrences of lymphopenia and discoid rash were oppositely associated with risk of incident proteinuria and the risk effects varied according to gender and patient age at onset of these manifestations. Thus, the risk of proteinuria may not be constant but could vary according to presentation of non-renal manifestations that may call for a differentiated clinical follow-up. Based on these findings, we suggest that the debut age of known prognostic factors, even prior to the SLE diagnosis should be considered when designing prognostic statistical models.References[1]Faurschou, M., et al., Prognostic factors in lupus nephritis: diagnostic and therapeutic delay increases the risk of terminal renal failure.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is an autoimmune disease with increased risk of cardiovascular complications such as coronary artery disease, myocarditis, pericarditis, and valvular dysfunction (1─3). The pathophysiological mechanisms are poorly understood and markers to identify high risk patients are warranted.ObjectivesWe aimed to identify SLE-characteristics that are associated with progressive cardiac dysfunction.MethodsA total of 108 patients with SLE (90 % female, mean age 46±13 years, median disease duration of 14 (7-21) years) were included from 2013 to 2014. Blood samples were collected with inclusion of biomarkers, and a standard echocardiography was performed at baseline and at a five-year follow-up. Multivariate regression analyses with five independent lupus-specific baseline variables of interest (disease activity, lupus nephritis, anti-cardiolipin and/or anti-beta-2 glycoprotein I antibodies, and lupus anticoagulant (LAC)) were performed for the association with baseline echocardiographic parameters as well as for changes during follow-up.ResultsDuring the five-year follow-up period, left ventricular (LV) end-diastolic volume index increased from 43.5±13.9 to 52.5±15.7 ml/m2 (p <0.001) (Figure 1 A1), and LV diastolic parameters declined (E/A ratio 1.4±0.5 vs. 1.3±0.5, p=0.002; e’ velocity 12.8±3.8 vs. 12.0±3.7 cm/s, p=0.02; mitral valve deceleration time 227.9 vs. 200.8 ms, p=<0.001), except for E/e’ (7.5±3.8 vs. 6.8±3.4, p=0.02) (Figure 1B1) in the entire SLE population. LV ejection fraction remained stationary (59.5±6.8 vs. 59.6±6.4 %, p=0.81). Presence of LAC was associated with progressive LV dilatation during the follow-up period (p=0.005) (Figure 1 A2) but not baseline LV volumes (p=0.35). LAC was associated with lower E/A ratio at baseline (p=0.006) but did not predict a decrease of E/A ratio during follow-up (p=0.09) (Figure 1 B2). Follow-up changes of other echocardiographic parameters were not associated with any of the lupus-specific variables.Figure 1.Left ventricular end-diastolic volume index (LVEDVI) (A) and E/A ratio (B) at baseline and follow-up (A1, B1) as well as paired longitudinal changes as density plots (A2, B2) with mean values (dashed lines) according to the presence of LAC (blue). LVEDVI and E/A ratio at baseline were log-transformed due to non-normality.ConclusionPresence of LAC was associated with lower E/A ratio at baseline as well as progressive left ventricular dilatation during a five-year follow-up period. Hence, LAC might be a predictor of progressive cardiac dysfunction in SLE patients. LAC is known to have implications for the microvascular circulation, but the clinical significance of the present findings is yet to be elucidated.References[1]Yafasova A, Fosbøl EL, Schou M, Baslund B, Faurschou M, Docherty KF, et al.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is a complex multiorgan autoimmune disease that primarily affects women during child-bearing years. The aetiology of SLE involves inadequate clearance of nuclear material released from apoptotic cells. The persistence of host DNA and RNA triggers the immune system to react as seen in a viral infection, causing persistent activation of antiviral interferon (IFN) signalling pathways. Aberrant production of IFN cytokines, type 1 in particular, results in elevated levels of >1000 IFN-regulated gene (IRG) expression in the blood, termed an IFN signature. The IFN signature is typically measured as a score combining the expression levels of a subset of 3-4 IRGs. Several cross-sectional studies have pointed to an association between the IFN signature and disease activity, however subsequent longitudinal studies and a recent systematic review by our group[1] have failed to reproduce these findings. It was suggested that the lack of association between the IFN signature and disease activity was because the IRGs that are sensitive to disease activity are not typically included in the subset of IRGs used to determine an IFN score[2]. Uncovering the significance of the IFN signature in SLE disease activity is particularly relevant for evaluating the scope of IFN pathway inhibitors and may explain why these fail to have a significance for the primary endpoint in clinical trials[3].Objectives-Determine the mRNA expression of a broad subset of IRGs (>100) in a cross-sectional study of SLE patients with diverse clinical manifestations-Investigate the association between IRG expression and disease activity-Validate the findings from a cross-sectional study in a longitudinal study of SLE patients with fluctuating disease activityMethodsIn a cross-sectional study, peripheral blood samples from 34 SLE patients and 15 healthy controls were collected in PAXgene tubes. Ten SLE patients were followed longitudinally, and peripheral blood samples were collected in PAXgene tubes at time of inclusion and after 12 months. Disease activity was assessed by SJ in all patients and determined by means of SLE Disease Activity Index 2000 (SLEDAI-2K) and European Consensus Lupus Activity Measurement Index (ECLAM). RNA from peripheral blood cells (PBCs) was extracted using the PAXgene Blood RNA kit. The mRNA transcripts of 128 IRGs were measured using the multiplexed NanoString nCounter Gene Expression platform. Bioinformatics and statistical analyses were performed using nSolver and SPSS software.ResultsOut of 128 IRGs, 46 were highly expressed in SLE patients as compared to controls and seemed to co-express in mainly two distinct clusters, Figure 1. Expression scores for cluster K1 did not correlate with SLEDAI or ECLAM in a cross-sectional setting, whereas K2 expression scores did (p<0.01). These findings were confirmed by correlation analysis of changes in K1 and K2 expression scores with scores of disease activity in a longitudinal setting.ConclusionInterferon signatures may express differentially with varying associations with disease activity.References[1]Siddiqi KZ, et al.

Abstract
BackgroundSystemic lupus erythematosus (SLE) has been associated with more than 100 genetic loci. This parallels positively to the clinical diversity that is reflected by the classification of SLE.ObjectivesWe aimed to investigate associations between disease manifestations of SLE and risk gene variants relevant to Danish subjects of European ancestry.MethodsWe included 427 SLE patients of European ancestry similar to previous reports.[1] We also included 89,699 controls from the Danish Blood Donor Study Genomic Cohort. SLE risk loci in this population were identified by genome-wide association methodology and hereafter correlated to cumulative occurrence of SLE classification items.ResultsFourteen variants mapped to the following genes: NCF2, STAT4, TNPO3/TPI1P2, IRF5, and ITGAM, were significantly associated (p<5E-8) with SLE.The five lead variants were associated (p<0.05) with the following manifestations; NCF2: proteinuria and anti-phospholipid antibodies, STAT4: arthritis, serositis, neurologic disorder, lymphopenia, and anti-Smith antibodies, IRF5: seizures and proteinuria, TNPO3: proteinuria, and ITGAM: photosensitivity (Table 2).ConclusionOur findings support the future use of select, relevant genetic markers in predicting various SLE phenotypes.References[1]Leffers HCB, Troldborg A, Voss A, et al.

Abstract
BackgroundPatients with systemic lupus erythematosus (SLE) display an aberrant DNA methylation (DNAm) pattern with a predominant interferon signature. However, the DNAm patterns in purified immune cell populations are not well described.ObjectivesTo examine genome-wide DNAm changes in sorted CD4+ T cells, monocytes, granulocytes and B cells in SLE patients compared to healthy controls (HC).MethodsGenome-wide analysis was performed in 20 SLE patients with active lupus nephritis (LN) and 20 age-, sex- and ethnicity-matched HCs. Peripheral blood was processed using gradient density centrifugation for the granulocyte fraction, and CD4+ T-cells, monocytes and B cells were isolated from the mononuclear cell fraction using a RoboSep device (Stemcell Technologies). DNA was extracted using the DNA/RNA/miRNA Universal kit (Qiagen). Genome-wide DNAm was evaluated using Infinium MethylationEPIC BeadChips (Illumina Inc.). Top differentially methylated CpG sites (DMC) were validated using pyrosequencing, and further analysed in follow-up samples, as well as extended to another 36 SLE patients with inactive LN, 36 SLE with never-LN and 20 HCs. Patients and HCs were compared using a paired t-test stratified by cell type. A false discovery rate (FDR) <0.05 was considered statistically significant. Clustering of non-gene annotated CpGs was defined as distance <5000 bp with proximity to neighbouring genes <1x105 bp, identified through mapping of Entrez Gene Identifiers.ResultsOverall, SLE patients with active LN compared to HCs exhibited DMCs in 22, 46, 312 and 78,068 probes in CD4+ T cells, monocytes, granulocytes and B cells, respectively. In CD4+ T cells, monocytes and granulocytes, the majority of DMCs were hypomethylated and related to interferon-regulated genes. In B cells, the majority of DMCs were hypermethylated with 1360 genes in the promoter region restricted to differential methylation >10% and ≥2 DMCs, of which 1087 were hypermethylated. Of these, the most significantly hypermethylated CpGs in the promoter region included CABYR, TMPRSS7, SLC6A2, KLK10/KLK11, WIZ, LPAR1, ZNF385B and IL1R1 (Figure 1). Top hypomethylated genes included IFI44L and MX1. Ingenuity Pathway Analysis (IPA) predicted top upstream regulators in B cells to be IL4, TNF and IFNG. In addition, we identified 1437 DMCs associated with ncRNA and 4626 DMCs with no genic association. The non-gene associated DMCs were related to 275 non-coding clusters. Top non-coding clusters were in proximity to BMP7, ARHGEF10, PRDM1, RIN2 and CCR6, which themselves were differentially methylated. IPA predicted IL2, CD40LG and NFKB1 as the most important upstream regulators for neighbouring genes of non-coding clusters.Pyrosequencing confirmed B cell hypermethylation in CXCR5, DDR1, MTA3, RAB30 and TRAF5, and in non-coding clusters located on chromosome 3 upstream of FGF12 and chromosome 22 downstream of XPNPEP3 and RBX1. Hypermethylation in CXCR5, DDR1, MTA3, RAB30 and hypomethylation in IFI44L, LGALS3BP and PARP9 was stable at follow-up as well as in patients with inactive and never-LN. Patients in the active LN group exhibited significantly more pronounced hypomethylation in PLSCR1 in CD4+ T-cells, granulocytes and B-cells compared to the other patient groups. Greater β2 microglobulin, anti-DNA antibodies and disease activity were significantly associated with greater B cell CXCR5 hypermethylation (p<0.001), IFI44L hypomethylation in all but CD4+ T cells, LGALS3BP hypomethylation in granulocytes (p<0.0001), PARP9 hypomethylation in all but B cells and PLSCR1 hypomethylation in all but monocytes. Proteinuria was related to PLSCR1 hypomethylation in all but monocytes, as well as hypermethylation at the non-coding cluster in chromosome 3 (p=0.05) and MTA3 (p=0.03) in B cells.ConclusionB cell hypermethylation in SLE patients is widespread, and may indicate a novel mechanism for SLE pathogenesis. Differential methylation of several interferon-regulated genes may be associated with disease activity.Disclosure of InterestsNone declared

Background
Systemic lupus erythematosus (SLE) is an autoimmune disease with increased risk of cardiovascular complications such as coronary artery disease, myocarditis, pericarditis and valvular dysfunction. The pathophysiological mechanisms are poorly understood and clinical, biochemical and/or imaging markers to identify high risk patients are warranted.
Purpose
We aimed to identify SLE-characteristics that are associated with progressive cardiac dysfunction during a five-year follow-up period in patients with SLE.
Methods
A total of 147 patients with SLE were included from 2013 to 2014. All patients underwent standard echocardiography at baseline as well as a collection of blood samples, including a selection of biomarkers. Patients were invited to a five-year follow-up with a total of 108 patients (90 % female, mean age 46 ± 13 years, median disease duration of 14 (7-21) years) completing a full echocardiographic, laboratory, and clinical examination. Multivariate regression analyses with eight independent baseline variables of interest (age, sex, disease activity (SLEDAI-2K), lupus nephritis, ischemic heart disease (IHD), antiphospholipid antibodies (IgM and IgG), and lupus anticoagulant(LAC)) were performed as for the association with baseline echocardiographic parameters as well as for changes during follow-up. Only echocardiographic measurements that changed significantly (p < 0.01) during follow-up were selected for the regression analyses. Left ventricular end-diastolic volume index (LVEDVI) and E/A ratio were log-transformed at baseline in the regression analyses due to non-normality.
Results
During a five-year follow-up period, LVEDVI increased from 43.5 ± 13.9 to 52.5 ± 15.7 ml/m2 (p <0.001), and left ventricular diastolic measures declined (E/A ratio 1.4 ± 0.5 vs. 1.3 ± 0.5, p = 0.002; e’ velocity 12.8 ± 3.8 vs. 12.0 ± 3.7 ms, p = 0.02; mitral valve deceleration time 227.9 vs. 200.8 ms, p < 0.001), except for E/e’ (7.5 ± 3.8 vs. 6.8 ± 3.4, p = 0.02). Left ventricular ejection fraction remained stationary (59.5 ± 6.8 vs. 59.6 ± 6.4 %, p = 0.81). In multivariate regression analyses, presence of LAC was significantly associated with progressive left ventricular dilation during the follow-up period (p = 0.003) but not with higher baseline levels (p = 0.64) (Fig. A1 & A2). LAC was associated with lower E/A ratio at baseline (p = 0.005) but did not predict a decrease of E/A ratio during follow-up (p = 0.24) (Fig. B1 & B2). IHD was associated with higher LVEDVI at baseline (p = 0.004), but not with further progression of dilation (p = 0.07).
Conclusion
Presence of LAC was associated with lower E/A ratio at baseline as well as progressive left ventricular dilation during a five-year follow-up period. Hence, LAC might be a predictor of progressive cardiac dysfunction in patients with SLE. LAC is known to have implications for the microvascular circulation, but the clinical significance of the present findings is yet to be elucidated. Abstract Figure A Abstract Figure B

Abstract
OBJECTIVE The objectives of this study was to establish a sensitive and reproducible method to map the cartilage and subchondral bone proteomes in quantitative terms, and mine the proteomes for proteins of particular interest in the pathogenesis of osteoarthritis (OA). The horse was used as a model animal. DESIGN Protein was extracted from articular cartilage and subchondral bone samples from three horses in triplicate by pressure cycling technology or ultrasonication. Digested proteins were analysed by data independent acquisition based mass spectrometry. Data was processed using a pre-established spectral library as reference database (FDR 1%). RESULTS We identified to our knowledge the hitherto most comprehensive quantitative cartilage (1758 proteins) and subchondral bone (1482 proteins) proteomes in all species presented to date. Both extraction methods were sensitive and reproducible and the high consistency of the identified proteomes (>97% overlap) indicated that both methods preserved the diversity among the extracted proteins. Proteome mining revealed a substantial number of quantifiable cartilage and bone matrix proteins and proteins involved in osteogenesis and bone remodeling, including ACAN, BGN, PRELP, FMOD, COMP, ACP5, BMP3, BMP6, BGLAP, TGFB1, IGF1, ALP, MMP3, and collagens. A number of proteins, including COMP and TNN, were identified in different protein isoforms with potential unique biological roles. CONCLUSION We have successfully developed two sensitive and reproducible non-species specific workflows enabling a comprehensive quantitative insight into the proteomes of cartilage and subchondral bone. This facilitates the prospect of investigating the molecular events at the osteochondral unit in the pathogenesis of OA in future projects.

Abstract
Objectives: Adult obesity may be positively associated with risks of rheumatoid arthritis (RA), but associations with early life body size are unknown. We examined whether birthweight, childhood body mass index (BMI), height, and changes in BMI and height were associated with risks of adult RA.Method: A cohort of 346 602 children (171 127 girls) from the Copenhagen School Health Records Register, born in 1930-1996, with measured weights and heights from 7 to 13 years of age, were included. Information on RA, including serological status, came from national registers from 1977 to 2017. Cox regressions were performed.Results: During a median of 35.1 years of observation time per person, 4991 individuals (3565 women) were registered with RA. Among girls, per BMI z-score, risks of RA and seropositive RA increased by 4-9% and 6-10%, respectively. Girls with overweight had higher risks of RA than girls without overweight. Girls who became overweight by 13 years of age had increased risks of RA compared to girls without overweight at 7 or 13 years (hazard ratio = 1.40, 95% confidence interval 1.19-1.66). For boys, associations between BMI and RA (including seropositive RA) were not statistically significant. Height was not associated with RA (any type) in girls. Taller boys had higher risks of RA, especially seropositive RA. Birthweight was not associated with RA.Conclusions: Among women, childhood adiposity was associated with increased risks of RA. Among men, childhood height was positively associated with risks of RA. These findings support the hypothesis that early life factors may be important in the aetiology of RA.

Abstract
Background:Remission, LDA and LDAS have been proposed as treatment goals for SLE. However, the independent impact of these states on damage accrual has not been fully evaluated.Objectives:To determine the independent impact of remission (both off & on treatment), LDA, and LLDAS on damage accrual.Methods:We studied a long-term longitudinal multinational SLE cohort, including patients completing at least two annual assessments. Remission off-treatment was defined as a SLEDAI (excluding serology) =0, without prednisone and immunosuppressive (IS) drugs. Remission on-treatment was defined as a SLEDAI (excluding serology) =0, prednisone daily dose<=5 mg/d and maintenance IS drugs. LDA was defined as a SLEDAI (excluding serology) <=2, without prednisone or IS drugs. LLDAS was defined as a SLEDAI <=4 with no activity in major organ systems, with no new features of lupus disease activity compared to the previous assessment, prednisone daily dose<=7.5 mg/d and maintenance IS drugs. Antimalarials were allowed in all groups. Damage accrual was ascertained with the SLICC/ACR damage index (SDI). Univariable and multivariable generalized estimated equation (GEE) negative binomial regression models were used. To create mutually exclusive groups, disease activity was divided into five states: remission off-treatment, remission on-treatment (minus remission off treatment), LDA (minus remission), LLDAS (minus remission and LDA) and not-optimally controlled. The proportion of the time that patients were in the specific state at each visit since cohort entry was determined. Possible effect modifiers and confounders adjusted for included sex, age at diagnosis, race/ethnicity, education, baseline disease duration, follow-up time, the highest-ever glucocorticoid dose prior to cohort entry, antimalarials and SDI. Time-dependent covariates were determined at the same annual visit as disease activity state; the outcome was the increase in the SDI and it was assessed at the subsequent visit.Results:There were 1,652 patients, 1464 (88.6%) were female, mean age at diagnosis was 34.6 (SD 13.4) years and mean baseline disease duration was 5.5 (SD 4.1) months. Patients had a mean follow-up of 6.5 (SD 4.3) years, 11686 visits were included. 763 patients (46.2%) had an increase in SDI score ≥1 during follow-up. 2483 (21.2%) of the visits were classified as remission off-treatment, 2276 (19.5%) as remission on-treatment, 544 (4.7%) as LDA, 657 (5.6%) as LLDAS and 5726 (49.0%) as not-optimally controlled. Being in remission off-treatment, remission on-treatment, LDA and LLDAS were predictive of a lower probability of damage accrual [remission off-treatment IRR=0.403, 95% CI 0.301-0.541); remission on-treatment IRR=0.313 (95% CI 0.218-0.451) LDA: IRR=0.469 (CI 95% CI 0.272-0.809); LLDAS IRR=0.440 (95% CI 0.241-0.803)].

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) can cause right dorsal colitis, but longitudinal clinical studies are lacking. This study investigates whether NSAID treated horses develop right dorsal colonic pathology in a clinical setting. Non-gastrointestinal hospitalized horses treated with NSAIDs >4 days, and untreated hospital-owned teaching horses and non-gastrointestinal client-owned hospitalized horses were included. All horses were monitored over time with clinical examinations (focusing on presence of colic, depression, reduced appetite, unstructured feces), ultrasonographic intestinal wall measurements, fecal occult blood tests (semi-quantitative results), and blood analysis (total protein and albumin concentrations, white blood cell and neutrophil counts). Outcomes were recorded as "ultrasonographically thickened right dorsal colon (RDC) walls", "colitis" and "right dorsal colitis". Findings over time were compared to baseline values and to control horses. Seventeen NSAID treated horses and 5 controls were included. NSAID treated horses developed thickened RDC walls (4/9), and subclinical and mild colitis (9/11) and right dorsal colitis (4/10), whereas all control horses remained healthy. The first changes were identified on treatment day 2. RDC walls of treated horses were significantly thicker compared to their own baseline values and compared to control horses. In conclusion, presumptive colon pathology was identified with a high incidence, starting early in the course of treatment, but with low severity. Appropriate monitoring should be advised throughout NSAID treatment. Additional research for noninvasive diagnostic tests for colon pathology is required.

Abstract
Circulating microvesicles (MVs) from patients with systemic lupus erythematosus (SLE) express the type 1 interferon (IFN)-inducible protein galectin-3 binding protein (G3BP), which may enhance their deposition in the glomerular basement membrane. The release of G3BP-expressing MVs from normal peripheral blood mononuclear cells (PBMCs) is induced by Toll-like receptor 9 (TLR-9) ligands, and these vesicles contain autoantibody-accessible double-stranded DNA (dsDNA). This study compares the release of MVs expressing G3BP and dsDNA from PBMCs derived from SLE patients with or without active lupus nephritis (LN) and from healthy donors, and taps further into the potential dependency on IFN-α for their generation and impacts of TLR-7/TLR-9 co-stimulation. PBMCs from 10 healthy donors and 12 SLE patients, six of whom had active LN at study inclusion, were stimulated in-vitro with recombinant human IFN-α and the TLR-9 agonists oligodeoxynucleotide (ODN)2216 or ODN2395 alone or in combination with the TLR-7 agonist gardiquimod. MVs in the supernatants were subsequently isolated by differential centrifugation and their expression of G3BP and dsDNA was quantified by flow cytometry. Stimulation with ODN2395 significantly increased the release of MVs co-expressing G3BP and dsDNA from PBMCs isolated from healthy donors and SLE patients. The expression of G3BP on individual MVs and the proportion of G3BP and dsDNA double-positive MVs released were increased in active LN patients. Neither co-stimulation with gardiquimod nor with the IFN-α inhibitor IN-1 had any effect on the MV release induced by ODN2395. In conclusion, the TLR-9-mediated inducibility of MVs co-expressing G3BP and dsDNA is increased in SLE patients with active LN.

Abstract
Background:EULAR/ACR 2019 SLE Classification Criteria were validated in an international cohort.Objectives:To evaluate performance characteristics of SLE classification systems in sex, race/ethnicity, and disease duration subsets.Methods:Sensitivity and specificity of the EULAR/ACR 2019, SLICC 2012 and ACR 1982/1997 criteria were evaluated in the validation cohort.Results:The cohort consisted of female (n=1098), male (n=172), Asian (n=118), Black (n=68), Hispanic (n=124) and White (n=941) patients; and patients with an SLE duration of 1-3 years (n=196), 3-5 years (n=157), and ≥5 years (n=879). Among patients with 1-3 years disease duration, the EULAR/ACR criteria had better sensitivity than the ACR criteria (97% (95%CI 92-99%) vs 81% (95%CI 72-88%). The new criteria performed well in men (sensitivity 93%, specificity 96%) and women (sensitivity 97%, specificity 94%). The new criteria had better sensitivity than the ACR criteria in White (95% vs 83%), Hispanic (100% vs 86%) and Asian patients (97% vs 77%).Conclusion:The EULAR/ACR 2019 criteria perform well in patients with early disease, and across sexes and ethnicities.Disclosure of Interests:Sindhu Johnson Grant/research support from: Boehringer Ingelheim, Corbus Pharmaceuticals, GlaxoSmithKline, Roche, Merck, Bayer, Consultant of: Boehringer Ingelheim, Ikaria, Ralph Brinks: None declared, Karen Costenbader Grant/research support from: Merck, Consultant of: Astra-Zeneca, David Daikh: None declared, Marta Mosca: None declared, Rosalind Ramsey-Goldman: None declared, Josef S.

Abstract
Background:SLE onset is preceded by a preclinical phase evidenced by the presence of anti-nuclear and other autoantibodies (autoAbs), which however, have low predictive value for development of clinical SLE.Objectives:To define the subgroup of autoAbs-positive individuals who are at high risk for progression into SLE by integrating environmental, clinical/serological, genetic and transcriptome data.Methods:A multicenter, across five European countries, inception cohort of autoAbs-positive individuals or first-degree relatives (FDRs) of SLE patients who are monitored prospectively over five years for possible transition to SLE according to the classification criteria. Structured data collection on demographics, family and medical history, clinical (criteria and selected non-criteria manifestations) and serological parameters, use of medications, hydroxyvitamin D levels and lifestyle (tobacco, alcohol use, physical activity, adherence to Mediterranean diet). Blood samples are stored for RNA-sequencing and genotyping.Results:A total 254 at-risk individuals (93% women, 99% Caucasians, aged [mean ± standard deviation] 36 ± 12 years) have been included and enrolment/monitoring is still ongoing. Forty individuals (16%) have FDR with SLE and 88 individuals (35%) have FDR with another autoimmune disorder. The frequency of active and past use of tobacco was 28% and 20%, respectively. Sedentary lifestyle (moving only for necessary chores or outdoor activity 1-2 times/week) was reported by 54% and adherence to the Mediterranean diet was low (3.4 ± 2.3, maximum score: 9). At enrolment, individuals had 1.9 ± 1.1 ACR-1997 classification criteria, with anti-nuclear antibodies (ANA) being the most frequent (88%), followed by synovitis (39%), photosensitivity (33%) and immunologic disorder (30%) (Table 1). During follow-up of 15.2 ± 7.2 months, a total 15 individuals (5.9%) have progressed into classified SLE, including cases with severe hematological and neurological disease.Table 1.Baseline characteristics of the at-risk for SLE cohortN (%) or mean ± SDACR 1997 classification criteria1.9 ± 1.1 Malar rash68 (27%) Discoid rash29 (11%) Photosensitivity83 (33%) Mucosal ulcers49 (19%) Synovitis100 (39%) Serositis30 (12%) Renal disorder28 (11%) Neurologic disorder31 (12%) Hematologic disorder58 (23%) Immunologic disorder77 (30%) ANA222 (88%)SLICC 2012 classification criteria Clinical criteria1.0 ± 0.9 Immunological criteria1.3 ± 0.9Conclusion:Among individuals with positive autoAbs or FDRs with SLE, the short-term risk for transition into clinical SLE is low.

Abstract
Background:Type I Interferons (IFNs), and especially INF-alpha, play a crucial role in the pathogenesis of SLE. Interferon-stimulated genes (ISGs) are generally up-regulated in SLE patients. Their pattern of up-regulation is often termed as an IFN signature. Even though composite IFN-scores are already used to express the up-regulation of the IFN-system, e.g. in studies testing therapeutic anti-IFN-antibodies, we are still lacking an in-depth understanding of the IFN signature.Objectives:To summarize the available data on the expression of ISGs in peripheral blood of patients with SLE compared to healthy controls; to assess which ISGs are most up-regulated in SLE patients; and to analyse if up-regulations of 6 ISGs typically used in IFN-scores [1,2] are associated with SLE disease activity and ethnicity.Methods:The electronic databases PubMed and EMBASE were searched using the terms “interferon signature”, “SLE”, “interferon-stimulated genes”, “microarray” and “gene expression” with inception date until Jan. 28, 2020. Original case-control studies containing quantitative data of ISG expression were included. Exclusion criteria were studies with animal models, clinical trials of drug treatment and studies withexvivo stimulation of cells prior to gene-expression analysis. Fold changes (FCs) (ISG expression in SLE/ISG expression in healthy controls) for the ISGs analysed in each study were extracted. FCs were plotted gene-wise on a heatmap for studies analysing ≥ 7 genes and for genes that were analysed in ≥ 5 studies. Cluster analysis using principle component analysis (PCA) and association analyses using generalized linear modelling (GLM) were performed for 6 ISGs (IFI27, IFI44, IFI44L, RSAD2, PRKR and IFIT1) as well as disease activity and ethnicity (SPSS).Results:16 case-control studies comprising a total of 851 SLE patients were included in the analyses, see Tab. 1. 24 ISGs had an average FC of ≥ 4. IFI27, RSAD2, IFI44L, IFI44, HERC5 and IFIT5 had an average FC > 6. The heatmap showed great variation in the expression of ISGs within the individual studies but also gene-wise between the studies, see Fig. 1. The inter-study variation was statistically explored for the selected 6 ISGs. PCA showed that PRKR, RSAD2, IFIT1, IFI44 and IFI44L clustered with African ancestry, see Fig. 2. Subsequent GLM confirmed that RSAD2 and PRKR were positively associated with African ancestry. However, none of the 6 ISGs were positively correlated with disease activity.Figure 1.Heatmap of ISG up-regulation.Figure 2.Principal component analysis.Conclusion:The degree of up-regulation of ISGs in SLE patients shows considerable variation within and between the individual studies. However, a pattern of up-regulation clearly emerges. We find a clustering of 5 prominent genes of the IFN signature (PRKR, RSAD2, IFIT1, IFI44 and IFI44L) and a positive correlation of RSAD2 and PRKR with African ancestry, pointing to the need to take ethnicity into account when using the IFN signature.

Abstract
Objective: The aim of this study was to investigate whether incident proteinuria in patients with systemic lupus erythematosus (SLE) was preceded by changes in blood lymphocytes and neutrophil counts and/or neutrophil-lymphocyte ratio (NLR).Method: SLE patients with no proteinuria before or at the time of classification were included. Longitudinal data on SLE manifestations, vital status, and SLE-associated medications were collected during clinical visits and chart review. Laboratory data were collected through a nationwide database. Lymphopenia, severe lymphopenia, and neutropenia were defined as values below 0.8 × 109, 0.5 × 109, and 2.0 × 109 cells/L, respectively. High NLR was defined as values above the median. Proteinuria was defined by at least two measurements of elevated urine protein excretion (> 0.5 g/day). Hazard ratios (HRs) were calculated by Cox modelling using time-dependent continuous and binary covariates based on multiple laboratory measurements adjusted for use of immunosuppressants.Results: In total, 260 SLE patients were available for the analysis, of whom 30 (12%) developed incident proteinuria following the diagnosis of SLE. Median follow-up time was 73.5 months. Lymphocyte and neutrophil counts, but not NLR, were associated with incident proteinuria. HRs for incident proteinuria were 2.71 for lymphopenia [95% confidence interval (CI) 1.20-6.11], 4.73 for severe lymphopenia (95% CI 1.93-11.59), and 2.54 for neutropenia (95% CI 1.14-5.65).Conclusion: Lymphopenia and neutropenia predicted the risk of first-time proteinuria independently of immunosuppressants.

Abstract
OBJECTIVE Peptidylarginine deiminase-4 (PAD4) is highly expressed by neutrophils and essential for citrullination occurring during the formation of neutrophil extracellular traps, which have been implicated in the pathogenesis of systemic lupus erythematosus (SLE) and lupus nephritis (LN). Single-nucleotide polymorphisms (SNPs) in PADI4 influence PAD4 expression and functionality. Here, we investigate whether SNPs in PADI4 influence the risk of SLE or LN. METHOD Altogether, 234 SLE patients and 484 controls were genotyped for nine PADI4 SNPs known to alter PAD4 functionality and/or expression, or to be associated with other autoimmune diseases, using an in-house multiplex Luminex assay. All analyses were adjusted for age and gender. RESULTS Heterozygosity for rs1748033, and heterozygosity and homozygosity for rs1635564, were associated with increased occurrence of SLE [odds ratio (OR) 1.55, 95% confidence interval (CI) 1.08-2.23; OR 1.52, 95% CI 1.06-2.19; and OR 2.06, 95% CI 1.08-3.93, respectively]. Homozygosity for rs1635564 was also associated with increased occurrence of LN (OR 3.35, 95% CI 1.2-10.97). Notably, gene dose effects of the rs1635564 variant allele were observed for SLE (p = 0.005) and LN (p = 0.01). Carriage of minor alleles of five other SNPs (rs11203366, rs11203367, rs874881, rs2240340, and rs11203368) was associated with increased occurrence of LN and hypertension. CONCLUSION The rs1635564 polymorphism of PADI4 is a candidate risk factor for SLE, particularly with renal involvement. Additional PADI4 polymorphisms also conferred increased risk of LN. Overall, these findings support the notion of PAD4 contributing to the pathogenesis of SLE and LN.

Abstract
BACKGROUND Studies have shown proximal diffusion of injected drugs in perineural blocks; such diffusion may affect specificity of the nerve block. OBJECTIVES To investigate the effect of a compression bandage applied to the pastern region on proximal diffusion of contrast medium injected over the palmar digital nerves. STUDY DESIGN Experimental study, randomised cross-over design. METHODS Radiodense contrast medium was injected over the lateral and medial palmar digital nerves of the left front limb of nine mature horses. Each horse was injected on two separate occasions, once with a 5 cm wide compression bandage applied proximal to the injection site and once without. The order of the two treatments was randomised with a wash-out period between treatments of at least 7 days. Radiographs were obtained at 5, 10, 20 and 30 min and distribution of the contrast column assessed. RESULTS Proximal distribution of the contrast medium was significantly reduced (P<0.01) with compression bandage. Furthermore, the compression bandage inhibited lymphatic drainage of the injected contrast medium. MAIN LIMITATIONS Clinical effect of the differences in diffusion length was not assessed. CONCLUSIONS The compression bandage reduced proximal diffusion and lymphatic drainage of contrast material causing it to stay localised around the injection site. Use of compression bandages could thus result in increased specificity of the nerve block and potentially prolong its effect.

Abstract
Objective The objective of this paper is to examine the association between plasma levels of β2-microglobulin (β2MG), a protein previously associated with atherosclerosis, and the presence of carotid plaque (CP) or coronary artery calcium (CAC) in a cross-sectional cohort study of patients with systemic lupus erythematosus (SLE). Methods Patients with SLE were enrolled between June 2013 and May 2014. The presence of CP and CAC was assessed with ultrasonography and computed tomography scan, respectively. The presence of CP or CAC in the SLE patients was analyzed with respect to plasma levels of β2MG and renal function expressed as the estimated glomerular filtration rate (eGFR). Results The study cohort consisted of 147 patients, 89% women and 95% Caucasians. The median age was 46 (range: 21-75) years with a median disease duration of 14 years. CP and CAC was observed in 29 (20%) and 57 (39%) of patients, respectively. CP or CAC was seen in 62 (42%) patients and was associated with the highest quartile of plasma β2MG in patients with eGFR ≥ 90 ml/min/1.73 m2; OR = 18 (95% CI: 1.7-181). β2MG adjusted for eGFR was also associated with presence of CP or CAC in the total cohort. The exclusion of 25 patients with a prior history of cardiovascular disease did not change the observed associations. Conclusion In this study, we found significant associations between imaging markers of atherosclerosis and high plasma levels of plasma β2MG. These data suggest that β2MG is a candidate for further study as a biomarker for atherosclerosis in SLE.

Abstract
BACKGROUND Serum amyloid A (SAA) is a major acute phase protein in horses. A new point-of-care (POC) test for SAA (Stablelab) is available, but studies evaluating its analytical accuracy are lacking. OBJECTIVES To evaluate the analytical performance of the SAA POC test by 1) determining linearity and precision, 2) comparing results in whole blood with those in serum or plasma, and 3) comparing POC results with those obtained using a previously validated turbidimetric immunoassay (TIA). STUDY DESIGN Assay validation. METHODS Analytical validation of the POC test was done in accordance with American Society of Veterinary Clinical Pathology guidelines using residual equine serum/plasma and whole blood samples from the Clinical Pathology Laboratory at the University of California-Davis. A TIA was used as the reference method. We also evaluated the effect of haematocrit (HCT). RESULTS The POC test was linear for SAA concentrations of up to at least 1000 μg/mL (r = 0.991). Intra-assay CVs were 13, 18 and 15% at high (782 μg/mL), intermediate (116 μg/mL) and low (64 μg/mL) concentrations. Inter-assay (inter-batch) CVs were 45, 14 and 15% at high (1372 μg/mL), intermediate (140 μg/mL) and low (56 μg/mL) concentrations. SAA results in whole blood were significantly lower than those in serum/plasma (P = 0.0002), but were positively correlated (r = 0.908) and not affected by HCT (P = 0.261); proportional negative bias was observed in samples with SAA>500 μg/mL. The difference between methods exceeded the 95% confidence interval of the combined imprecision of both methods (15%). MAIN LIMITATIONS Analytical validation could not be performed in whole blood, the sample most likely to be used stall side. CONCLUSION The POC test has acceptable accuracy and precision in equine serum/plasma with SAA concentrations of up to at least 1000 μg/mL. Low inter-batch precision at high concentrations may affect serial measurements, and the use of the same test batch and sample type (serum/plasma or whole blood) is recommended. Comparison of results between the POC test and the TIA is not recommended.

Abstract
OBJECTIVE To investigate serum interleukin-6 (IL-6), serum chitinase-3-like protein-1 (YKL-40), and plasma vascular endothelial growth factor (VEGF) as measures of disease activity and predictors of clinical remission and radiographic progression in two early rheumatoid arthritis (RA) randomized controlled trials (RCTs). METHOD Treatment-naïve patients with early RA (< 6 months' duration) and active disease, participating in two investigator-initiated RCTs, were treated according to a predefined treat-to-target algorithm aiming at inflammatory control, using methotrexate (MTX) + cyclosporine versus MTX + placebo (CIMESTRA study, n = 150, 5 year follow-up) or MTX + adalimumab versus MTX + placebo (OPERA study, n = 180, 2 year follow-up). The 28-joint Disease Activity Score (DAS28) and conventional radiography [bilateral hands and feet at baseline, 2 years and 5 years (only CIMESTRA)] were obtained at baseline and during follow-up. Serum IL-6, serum YKL-40, and plasma VEGF were measured in baseline blood samples and during follow-up. Hypotheses regarding the biomarkers' relation with DAS28 and ability to predict clinical remission (DAS28 < 2.6) and radiographic progression (change in total Sharp van der Heijde score ≥ 2) were generated in CIMESTRA and validated in OPERA, by Spearman's correlation and logistic regression analyses. RESULTS Baseline IL-6, YKL-40, and VEGF correlated significantly with DAS28 in CIMESTRA (r = 0.50, r = 0.36, r = 0.36, respectively, all p < 0.01) and these results were confirmed in OPERA patients (r = 0.52, p < 0.01; r = 0.18, p = 0.01; r = 0.23, p = 0.002, respectively). None of the biomarkers (absolute values or change) was predictive of clinical remission or radiographic progression at 2 or 5 years in either study. CONCLUSION Serum IL-6, serum YKL-40, and plasma VEGF were significantly correlated with DAS28 at baseline, but did not have consistent predictive value for clinical remission or radiographic progression in two early RA RCTs.

Abstract
Objective To determine the level of agreement of disease flare severity (distinguishing severe, moderate, and mild flare and persistent disease activity) in a large paper‐patient exercise involving 988 individual cases of systemic lupus erythematosus. Methods A total of 988 individual lupus case histories were assessed by 3 individual physicians. Complete agreement about the degree of flare (or persistent disease activity) was obtained in 451 cases (46%), and these provided the reference standard for the second part of the study. This component used 3 flare activity instruments (the British Isles Lupus Assessment Group [BILAG] 2004, Safety of Estrogens in Lupus Erythematosus National Assessment [SELENA] flare index [SFI] and the revised SELENA flare index [rSFI]). The 451 patient case histories were distributed to 18 pairs of physicians, carefully randomized in a manner designed to ensure a fair case mix and equal distribution of flare according to severity. Results The 3‐physician assessment of flare matched the level of flare using the 3 indices, with 67% for BILAG 2004, 72% for SFI, and 70% for rSFI. The corresponding weighted kappa coefficients for each instrument were 0.82, 0.59, and 0.74, respectively. We undertook a detailed analysis of the discrepant cases and several factors emerged, including a tendency to score moderate flares as severe and persistent activity as flare, especially when the SFI and rSFI instruments were used. Overscoring was also driven by scoring treatment change as flare, even if there were no new or worsening clinical features. Conclusion Given the complexity of assessing lupus flare, we were encouraged by the overall results reported. However, the problem of capturing lupus flare accurately is not completely solved.

Abstract
BACKGROUND Strongylus vulgaris is re-emerging in horses kept under surveillance-based parasite control regimens. Information on nonstrangulating intestinal infarction associated with S. vulgaris is needed to improve recognition of the condition. OBJECTIVE To describe the typical clinical presentation, laboratory findings, gross pathology, treatment and outcome of horses with nonstrangulating intestinal infarction. STUDY DESIGN Retrospective case series. METHODS Nonstrangluating intestinal infarction was diagnosed in 30 horses with a localised intestinal infarction with concurrent signs of S. vulgaris migration and no signs of intestinal strangulation or enterocolitis. Data were obtained from medical records in the period 2008-2016. Long-term follow-up information was obtained by telephonic interviews. Levels of S. vulgaris-specific antibodies were retrospectively assessed. Associations between nonstrangulating intestinal infarction and selected variables were evaluated using Fisher's exact and Mann-Whitney U tests. RESULTS The most consistent findings at admission were mild colic of >24 h duration without signs of shock or strangulated intestine, increased peritoneal fluid WBC (>5 × 109 /L), increased serum amyloid A (SAA) concentration and a positive S. vulgaris-specific antibody titre. Medical treatment was attempted in nine horses with none surviving. Exploratory laparotomy was performed in 21 horses. Eleven horses were subjected to euthanasia intraoperatively due to the presumed poor prognosis. Of the nine horses, three (33%) undergoing intestinal resection survived to discharge. The surviving horses were alive and returned to athletic function for at least 2 years following discharge. MAIN LIMITATIONS Only nine of the 30 horses underwent resection of the infarcted intestine, and the prognosis for surgical intervention in nonstrangulating intestinal infarction is, therefore, difficult to estimate. CONCLUSIONS In areas where S. vulgaris is prevalent, nonstrangulating intestinal infarction should be considered as a differential diagnosis in horses presenting with mild colic and peritonitis. Survival of nonstrangulating intestinal infarction is possible in cases where surgical intervention with resection of the infarcted intestine is feasible. The summary is available in Spanish - see Supporting Information.

Abstract
OBJECTIVE Cardiac events are a major cause of death in patients with idiopathic inflammatory myopathies. The study objective was in a controlled setting to describe cardiac abnormalities by noninvasive methods in a cohort of patients with polymyositis (PM) or dermatomyositis (DM) and to identify predictors for cardiac dysfunction. METHODS In a cross-sectional study, 76 patients with PM/DM and 48 matched healthy controls (HCs) were assessed by serum levels of cardiac troponin I, electrocardiography, Holter monitoring, echocardiography with tissue Doppler imaging, and quantitative cardiac (99m) Tc-pyrophosphate ((99m) Tc-PYP) scintigraphy. RESULTS Compared to HCs, patients with PM/DM more frequently had left ventricular diastolic dysfunction (LVDD) (12% versus 0%; P = 0.02) and longer QRS and QT intervals (P = 0.007 and P < 0.0001, respectively). In multivariate analysis, factors associated with LVDD were age (P = 0.001), disease duration (P = 0.004), presence of myositis-specific or -associated autoantibodies (P = 0.05), and high cardiac (99m) Tc-PYP uptake (P = 0.006). In multivariate analysis of the pooled data for patients and HCs, a diagnosis of PM/DM (P < 0.0001) was associated with LVDD. CONCLUSION Patients with PM or DM had an increased prevalence of cardiac abnormalities compared to HCs. LVDD was a common occurrence in PM/DM patients and correlated to disease duration. In addition, the association of LVDD with myositis-specific or -associated autoantibodies and high cardiac (99m) Tc-PYP uptake supports the notion of underlying autoimmunity and myocardial inflammation in patients with PM/DM.

Abstract
Since early November 2016, the number of laboratory-confirmed norovirus infections reported in Germany has been increasing steeply. Here, we report the detection and genetic characterisation of an emerging norovirus recombinant, GII.P16-GII.2. This strain was frequently identified as the cause of sporadic cases as well as outbreaks in nine federal states of Germany. Our findings suggest that the emergence of GII.P16-GII.2 contributed to rising case numbers of norovirus gastroenteritis in Germany.

Abstract
In humans, biofilm is a well-known cause of delayed healing and low-grade inflammation of chronic wounds. In horses, biofilm formation in wounds has been studied to a very limited degree. The objective of this study was thus to investigate the occurrence of biofilm in equine experimental wounds healing by secondary intention. Tissue biopsies from non-contaminated, experimental excisional shoulder and limb wounds were obtained on day 1-2, day 7-10 and day 14-15 post-wounding. Limb wounds were either un-bandaged or bandaged to induce exuberant granulation tissue (EGT) formation and thereby impaired healing. Presence of biofilm in tissue biopsies was assessed by peptide nucleic acid fluorescence in situ hybridization (PNA FISH) and confocal laser scanning microscopy (CLSM). Bandaged limb wounds developed EGT and displayed delayed healing, while shoulder and un-bandaged limb wounds healed normally. Biofilm was detected in limb wounds only. At day 14-15 biofilm was significantly more prevalent in bandaged limb wounds than in un-bandaged limb wounds (P=0.003). Further, bandaged limb wounds had a statistically significant increase in biofilm burden from day 7-10 to day 14-15 (P=0.009). The finding that biofilm was most prevalent in bandaged limb wounds with EGT formation suggests that biofilm may be linked to delayed wound healing in horses, as has been observed in humans. The inability to clear bacteria could be related to hypoxia and low-grade inflammation in the EGT, but the interaction between biofilm forming bacteria and wound healing in horses needs further elucidation.

Abstract
Background/purpose The objective of this study was to explore the impact of systemic lupus erythematosus and belimumab given in addition to standard of care therapy on 13-valent conjugated pneumococcal vaccine (PCV13) response. Methods Forty-seven systemic lupus erythematosus patients and 21 healthy controls were immunized with a single dose of 13-valent conjugated pneumococcal vaccine. Forty systemic lupus erythematosus patients were treated with traditional disease-modifying anti rheumatic drugs, 11 of those received belimumab in addition, and 32 patients were treated with concomitant prednisolone. Quantification of serotype specific IgG levels to 12 pneumococcal capsular polysaccharides was performed in serum taken before and four to six weeks after vaccination using multiplex fluorescent microsphere immunoassay. IgG levels against serotypes 23F and 6B were also analyzed using standard enzyme-linked immunosorbent assays. Opsonophagocytic assay was performed on serotype 23F to evaluate the functionality of the antibodies. Pre- and post-vaccination log transformed antibody levels were compared to determine the impact of systemic lupus erythematosus diagnosis and different treatments on antibody response. Results Systemic lupus erythematosus patients as a group showed lower post-vaccination antibody levels and lower fold increase of antibody levels after vaccination compared to controls ( p = 0.02 and p = 0.009, respectively). Systemic lupus erythematosus patients treated with belimumab in addition to standard of care therapy or with only hydroxychloroquine did not differ compared to controls, whereas the other treatment groups had significantly lower fold increase of post-vaccination antibody levels. Higher age was associated with lower post-vaccination antibody levels among systemic lupus erythematosus patients. Conclusion Belimumab given in addition to traditional disease-modifying anti rheumatic drugs or prednisolone did not further impair antibody response to 13-valent conjugated pneumococcal vaccine.

Objective There is a decreased breast cancer risk in systemic lupus erythematosus (SLE) versus the general population. We assessed a large sample of SLE patients, evaluating demographic and clinical characteristics and breast cancer risk. Methods We performed case-cohort analyses within a multi-center international SLE sample. We calculated the breast cancer hazard ratio (HR) in female SLE patients, relative to demographics, reproductive history, family history of breast cancer, and time-dependent measures of anti-dsDNA positivity, cumulative disease activity, and drugs, adjusted for SLE duration. Results There were 86 SLE breast cancers and 4498 female SLE cancer-free controls. Patients were followed on average for 7.6 years. Versus controls, SLE breast cancer cases tended to be white and older. Breast cancer cases were similar to controls regarding anti-dsDNA positivity, disease activity, and most drug exposures over time. In univariate and multivariate models, the principal factor associated with breast cancers was older age at cohort entry. Conclusions There was little evidence that breast cancer risk in this SLE sample was strongly driven by any of the clinical factors that we studied. Further search for factors that determine the lower risk of breast cancer in SLE may be warranted.

Abstract
We investigated if signs of active Epstein-Barr virus and cytomegalovirus infections associate with certain autoantibodies and a marker of type I interferon activity in patients with systemic lupus erythematosus. IgM and IgG plasma levels against Epstein-Barr virus early antigen diffuse and cytomegalovirus pp52 were applied as humoral markers of ongoing/recently active Epstein-Barr virus and cytomegalovirus infections, respectively. Plasma galectin-3 binding protein served as a surrogate marker of type I interferon activity. The measurements were conducted in 57 systemic lupus erythematosus patients and 29 healthy controls using ELISAs. Regression analyses and univariate comparisons were performed for associative evaluation between virus serology, plasma galectin-3 binding protein and autoantibodies, along with other clinical and demographic parameters. Plasma galectin-3 binding protein concentrations were significantly higher in systemic lupus erythematosus patients (P = 0.009) and associated positively with Epstein-Barr virus early antigen diffuse-directed antibodies and the presence of autoantibodies against extractable nuclear antigens in adjusted linear regressions (B = 2.02 and 2.02, P = 0.02 and P = 0.002, respectively). Furthermore, systemic lupus erythematosus patients with anti-extractable nuclear antigens had significantly higher antibody levels against Epstein-Barr virus early antigen diffuse (P = 0.02). Our study supports a link between active Epstein-Barr virus infections, positivity for anti-extractable nuclear antigens and increased plasma galectin-3 binding protein concentrations/type I interferon activity in systemic lupus erythematosus patients.

Abstract
Objective To describe the frequency of myocardial infarction (MI) prior to the diagnosis of systemic lupus erythematosus (SLE) and within the first 2 years of follow-up. Methods The systemic lupus international collaborating clinics (SLICC) atherosclerosis inception cohort enters patients within 15 months of SLE diagnosis. MIs were reported and attributed on a specialised vascular event form. MIs were confirmed by one or more of the following: abnormal ECG, typical or atypical symptoms with ECG abnormalities and elevated enzymes (≥2 times upper limit of normal), or abnormal stress test, echocardiogram, nuclear scan or angiogram. Descriptive statistics were used. Results 31 of 1848 patients who entered the cohort had an MI. Of those, 23 patients had an MI prior to SLE diagnosis or within the first 2 years of disease. Of the 23 patients studied, 60.9% were female, 78.3% were Caucasian, 8.7% black, 8.7% Hispanic and 4.3% other. The mean age at SLE diagnosis was 52.5±15.0 years. Of the 23 MIs that occurred, 16 MIs occurred at a mean of 6.1±7.0 years prior to diagnosis and 7 occurred within the first 2 years of follow-up. Risk factors associated with early MI in univariate analysis are male sex, Caucasian, older age at diagnosis, hypertension, hypercholesterolaemia, family history of MI and smoking. In multivariate analysis only age (OR=1.06 95% CI 1.03 to 1.09), hypertension (OR=5.01, 95% CI 1.38 to 18.23), hypercholesterolaemia (OR=4.43, 95% CI 1.51 to 12.99) and smoking (OR=7.50, 95% CI 2.38 to 23.57) remained significant risk factors. Conclusions In some patients with lupus, MI may develop even before the diagnosis of SLE or shortly thereafter, suggesting that there may be a link between autoimmune inflammation and atherosclerosis.

Abstract
Anthelmintics and vaccines are commonly given concurrently in routine equine management, but it is unknown to what extent an interaction between the two exists. Cyathostomins can modulate the local immune response by stimulating a type 2 helper T cell (Th2) response. In addition, anti-inflammatory effects of ivermectin have been found in rodent models. It is unknown whether these anti-inflammatory effects affect the acute phase response elicited by commonly used vaccines. This study evaluated how the acute phase inflammatory response, leukocyte expression of pro-inflammatory cytokines, and vaccine-specific titers induced by simultaneous injection of three vaccines (West Nile Virus, Equine Herpes Rhinopneumonitis, and Keyhole Limpet Hemocyanin) were modulated by concurrent administration of ivermectin or pyrantel pamoate in ponies naturally infected with cyathostomins. Mixed-breed yearling ponies were blocked by gender and fecal strongyle egg count, then randomly assigned to three treatment groups: ivermectin (n=8), pyrantel pamoate (n=8), and control (n=7). All ponies received vaccinations intramuscularly on days 0 and 29, and anthelmintics were administered on the same days. Whole blood, serum and plasma samples were collected one, three and 14 days after each vaccination. Samples were analyzed for concentrations of acute phase reactants (haptoglobin, serum amyloid A, fibrinogen and iron), mRNA expression levels of cytokines (interleukin (IL)-1β, IL-4, IL-10, tumor necrosis factor (TNF)-α and interferon (IFN)-γ) in leukocytes, and vaccine-specific antibody titers. A marked acute-phase response was noted following both vaccinations. In contrast, the pattern of change in cytokine expression was less pronounced and more variable. Statistical differences were observed between groups for haptoglobin, fibrinogen, IL-1β, IL-4, and IL-10, but differences were generally small and none of the vaccine titers were different between the groups. Taken together, the study found some signs of modulation of immunologic or inflammatory responses to the administered vaccines, when anthelmintics were administered concurrently, but these are unlikely to have practical implications for vaccination routines.

Abstract
OBJECTIVE A high level of galectin-3-binding protein (G3BP) appears to distinguish circulating cell-derived microparticles in systemic lupus erythematosus (SLE). The aim of this study is to characterize the population of G3BP-positive microparticles from SLE patients compared to healthy controls, explore putative clinical correlates, and examine if G3BP is present in immune complex deposits in kidney biopsies from patients with lupus nephritis. METHODS Numbers of annexin V-binding and G3BP-exposing plasma microparticles from 56 SLE patients and 36 healthy controls were determined by flow cytometry. Quantitation of microparticle-associated G3BP, C1q and immunoglobulins was obtained by liquid chromatography tandem mass spectrometry (LC-MS/MS). Correlations between microparticle-G3BP data and clinical parameters were analyzed. Co-localization of G3BP with in vivo-bound IgG was examined in kidney biopsies from one non-SLE control and from patients with class IV (n = 2) and class V (n = 1) lupus nephritis using co-localization immune electron microscopy. RESULTS Microparticle-G3BP, microparticle-C1q and microparticle-immunoglobulins were significantly (P < 0.01) increased in SLE patients by LC-MS/MS. Three G3BP-exposing microparticle populations could be discerned by flow cytometry, including two subpopulations that were significantly increased in SLE samples (P = 0.01 and P = 0.0002, respectively). No associations of G3BP-positive microparticles with clinical manifestations or disease activity were found. Immune electron microscopy showed co-localization of G3BP with in vivo-bound IgG in glomerular electron dense immune complex deposits in all lupus nephritis biopsies. CONCLUSIONS Both circulating microparticle-G3BP numbers as well as G3BP expression are increased in SLE patients corroborating G3BP being a feature of SLE microparticles. By demonstrating G3BP co-localized with deposited immune complexes in lupus nephritis, the study supports cell-derived microparticles as a major autoantigen source and provides a new understanding of the origin of immune complexes occurring in lupus nephritis.

Abstract
Background The acute phase proteins (APP) serum amyloid A (SAA), haptoglobin, and fibrinogen are valuable blood biomarkers in equine inflammatory diseases, but knowledge of factors influencing their concentrations in blood and peritoneal fluid (PF) of horses with colic is needed. Objectives The objective of this study was to investigate the influence of demographics (age, sex, breed), disease process (simple obstruction, strangulating obstruction, inflammatory), disease location, disease duration, hypovolemia, and admission hospital on concentrations of APP, lactate and white blood cell counts (WBC) in horses with colic admitted to 2 referral hospitals. Animals The study included 367 horses with colic admitted at 2 referral hospitals. Methods Prospective multicenter observational study of clinical data, as well as blood and PF biomarkers. Associations between biomarker concentrations and clinical variables were analyzed using multivariate linear regression analysis. Results Increasing pre‐admission duration of colic was associated with increased concentrations of APP in blood and PF. Blood concentrations of SAA and fibrinogen were associated with disease process (inflammatory, strangulations, simple obstructions) in more colic duration groups (5–12 and >24 hours) than any of the other biomarkers. No relevant associations between demographic factors, hospital, or hydration status and the measured biomarkers were found. Conclusions and Clinical Importance In horses with colic, concentrations of APP are associated mainly with disease process and duration of colic and may thus be used for assessment of disease independently of demographic or geographic factors. Serum amyloid A may be a diagnostic marker for use in colic differential diagnosis, but further evaluation is needed.

Abstract
OBJECTIVES We investigated the antibody levels against early antigens of Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpesvirus 6 (HHV6) in systemic lupus erythematosus (SLE) patients and healthy controls, and further correlated these antibodies to haematology/biochemistry, serology, and disease activity measures. METHOD Immunoglobulin (Ig)M, IgG, and IgA levels against the DNA polymerase processivity factors of EBV, CMV, and HHV6, termed early antigen diffuse (EA/D), pp52, and p41, respectively, were determined in plasma samples from 77 SLE patients and 29 healthy controls by using enzyme-linked immunosorbent assays (ELISAs). RESULTS IgM, IgG, and IgA levels against EBV EA/D, and IgG and IgA levels against CMV pp52, were significantly higher in SLE patients compared with healthy controls. Furthermore, EBV EA/D- and CMV pp52-directed IgG levels were inversely and positively associated, respectively, with lymphocyte counts in SLE patients. None of the findings seemed to be associated with use of immunosuppressive medication. CONCLUSIONS Our results suggest strong, but opposite, associations of lytic EBV and CMV infections with SLE. The amplified humoral responses to EBV EA/D and CMV pp52 in our SLE patient cohort probably reflect aberrant control of EBV and CMV reactivation. However, reactivation of EBV appeared to correlate with lymphopenic manifestations in SLE patients whereas CMV reactivation seemed to correlate with increments in lymphocyte levels.

Abstract
OBJECTIVES We aimed to determine 1) ultrasound (US) abnormalities in patients with systemic lupus erythematosus (SLE) with and without hand arthralgia at the day of examination compared with clinical evaluation and healthy controls, and 2) inter-observer reliability of the US abnormalities. METHODS Thirty-three female SLE patients were twice examined with US by three trained examiners. Using B-mode and Doppler US, unilateral wrist and metacarpophalangeal (MCP) joints were examined for synovitis and erosions as well as signs of hand tenosynovitis using a GE Logiq 9 US machine with Doppler settings for slow flow. All patients also underwent clinical joint evaluation and were compared with 11 healthy controls (HC). RESULTS Among the patients with SLE 16 (48%) had signs of wrist synovitis, which was only observed in one HC (p = 0.03). Corresponding figures for any MCP joint were 12 (36%) and 0 (p = 0.06). In SLE patients, 18% had hand tenosynovitis and 6% bone erosions. Wrist synovitis was detected by US in 16 SLE patients (81%) with arthralgia compared with 17 patients without (18%) (p = 0.0005). Any US abnormalities were observed in 44% of 25 wrists without tenderness at clinical examination and in 46% of 26 wrists without swelling. Corresponding percentages for MCP2 joints were 27% and 21%. Inter-observer reliability of the US findings was good to excellent for examination of hand joints and tendons. CONCLUSIONS A majority of SLE patients with hand arthralgia showed US signs of synovitis, erosions and tenosynovitis indicating subclinical disease. Even SLE patients without clinical signs of joint inflammation demonstrated US abnormalities. Good to excellent inter-observer reliability was found in US evaluation of hands in patients with SLE.

Abstract
This study aimed to demonstrate possible associations between genetic polymorphisms in Toll-like receptor 3, interferon induced with helicase C domain 1 (IFIH1) and DEAD (Asp-Glu-Ala-Asp) box polypeptide 58 and systemic lupus erythematosus (SLE), including the phenotypes lupus nephritis and malar rash, as well as the presence of autoantibodies against nucleic acid-containing complexes. Genotyping was carried out in two Danish cohorts [Copenhagen (CPH) and Odense (ODE)] totaling 344 patients and was compared with 641 previously genotyped healthy controls. In the ODE cohort, the patients were only genotyped for the rs1990760 polymorphism of IFIH1. Single nucleotide polymorphisms (SNPs) were determined by a multiplex bead-based assay (CPH cohort) or real-time PCR (ODE cohort). Associations were investigated using the Cochran-Armitage trend test. The odds ratio (OR) for minor allele homozygotes versus major allele homozygotes suggested a protective effect of the IFIH1 rs1990760 SNP for SLE in the ODE cohort [OR 0.52, 95 % confidence intervals (95 % CI) 0.31-0.88, Pcorr. = 0.05] but not in the CPH cohort, although the OR suggested a trend in the same direction, and when combining the two patient cohorts, ORs were 0.57, 95 % CI 0.37-0.88. None of the other investigated polymorphisms showed any association with SLE. Regarding phenotypes, we found a statistically significant association between rs1990760 and malar rash in the CPH cohort, with ORs suggesting a protective effect (OR 0.28, 95 % CI 0.13-0.62 for heterozygotes and OR 0.11, 95 % CI 0.03-0.41 for homozygotes, Pcorr. = 0.0001). There were no significant associations between rs1990760 and presence of anti-dsDNA, anti-U1RNP, or anti-Smith antibodies. Our study supports previous findings of an association between the rs1990760 polymorphism of IFIH1 and SLE and indicates that this SNP may also be associated with malar rash in SLE patients although this finding needs confirmation.
