Risk of cardiovascular comorbidities before and after the onset of rheumatic diseases.

OBJECTIVES: To elucidate the risk and temporal relationship of cardiovascular (CV) comorbidities in rheumatic diseases. METHODS: Patients in the FinnGen study diagnosed between 2000 and 2014 with seropositive (n = 2368) or seronegative (n = 916) rheumatoid arthritis (RA), ankylosing spondylitis (AS, n = 715), psoriatic arthritis (PsA, n = 923), systemic lupus erythematosus (SLE, n = 190), primary Sjogren's syndrome (pSS, n = 412) or gout (n = 2034) were identified from healthcare registries. Each patient was matched based on age, sex, and birth region with twenty controls without any rheumatic conditions. Overall risk ratios (RR) were calculated by comparing the prevalence of seven CV diseases between patients and controls. Logistic regression models were used for estimating odds ratios (OR) for CV comorbidities before and after the onset of rheumatic diseases. RESULTS: The RR for 'any CVD' varied from 1.14 (95 % confidence interval [CI] 1.02-1.26) in PsA to 2.05 (95 % CI 1.67-2.52) in SLE. Patients with SLE or gout demonstrated over two-fold risks for several CV comorbidities. Among CV comorbidities, venous thromboembolism (VTE) showed the highest effect sizes in several rheumatic diseases. The ORs for CV comorbidities were highest within one year before and/or after the onset of the rheumatic disease. However, in gout the excess risk of CV disease was especially high before gout diagnosis. CONCLUSIONS: The risk of CV comorbidities was elevated in all studied rheumatic diseases, with highest risks observed in SLE and gout. The risk for CV diseases was highest immediately before and/or after rheumatic disease diagnosis, highlighting the increased risk for CV comorbidities across all rheumatic diseases very early on the disease course.

[Nonpharmacological treatment measures, rehabilitation services and membership in patient support groups in axial spondylarthritis (The ATTENTUS axSpA study)]. / Nichtmedikamentöse Therapiemaßnahmen, Rehabilitationsleistungen und Mitgliedschaft in Selbsthilfeorganisationen bei axialer Spondyloarthritis (Die ATTENTUS axSpA-Studie).

BACKGROUND: The treatment of axial spondylarthritis (axSpA) includes pharmacological treatment measures (PTM) and nonpharmacological treatment measures (NPTM) as well as supporting resources, such as rehabilitation services (RS) and membership in patient support groups (PSG). Nevertheless, there are significant participation restrictions in patients with axSpA in Germany. OBJECTIVE: Investigation of functional deficits, participation restrictions and utilization of PTM, NPTM, RS and PSG membership in patients with axSpA. MATERIAL AND METHODS: Multicentric, observational study of 770 axSpA patients in Germany (ATTENTUS-axSpA). RESULTS: Substantial functional deficits and participation restrictions were observed in axSpA patients. Of the patients 39% did not receive treatment with biological disease-modifying antirheumatic drugs (bDMARD). In the NPTM 54% received physiotherapy less than once per week and 29% once per week. Physical activities were regularly performed by 86% of patients, mainly in the form of home exercises. Training in a gym (14%) or sports club (7%) was carried out much less frequently. Of the patients 54% received RS, one third had the last rehabilitation more than 5 years ago and 13% of the patients were members in a PSG. A significantly higher utilization of NPTM and rehabilitation was found in this group. CONCLUSION: Treatment options and resources were often utilized to a small extent and/or in low intensity by axSpA patients, which could be a possible explanation for persisting restrictions of participation. Membership in a PSG was associated with an increased utilization of NPTM and RS.

The impact of psoriasis on wellbeing and clinical outcomes in juvenile psoriatic arthritis.

OBJECTIVES: Juvenile psoriatic arthritis (JPsA) has varied clinical features that are distinctive to other juvenile idiopathic arthritis (JIA) categories. This study investigates whether such features impact patient-reported and clinical outcomes. METHODS: Children and young people (CYP) were selected if recruited to the Childhood Arthritis Prospective Study, a UK multicentre JIA inception cohort, between January 2001 and March 2018. At diagnosis, patient/parent-reported outcomes (as age-appropriate) included the parental global assessment (10 cm VAS), functional ability (CHAQ), pain (10 cm VAS), health-related quality of life (CHQ psychosocial score), mood/depressive symptoms (MFQ) and parent psychosocial health (GHQ). Three-year outcome trajectories have previously been defined using active joint counts, physician and parent global assessments (PGA, PaGA respectively). Patient-reported outcomes and outcome trajectories were compared in i) CYP with JPsA versus other JIA categories, ii) CYP within JPsA, with and without psoriasis via multivariable linear regression. RESULTS: There were no significant differences in patient-reported outcomes at diagnosis between CYP with JPsA and non-JPsA. Within JPsA, those with psoriasis had more depressive symptoms (coefficient = 9.8, 95% CI = 0.5-19.0) than those without psoriasis at diagnosis. CYP with JPsA had 2.3 times the odds of persistent high PaGA than other ILAR categories, despite improving joint counts and PGA (95% CI 1.2, 4.6). CONCLUSION: CYP with psoriasis at JPsA diagnosis report worse mood, supporting a greater disease impact in those with both skin and joint involvement. Multidisciplinary care with added focus to support wellbeing in children with JPsA plus psoriasis may help improve these outcomes.

Is the risk of infection higher during treatment with secukinumab than with TNF inhibitors? An observational study from the Nordic countries.

OBJECTIVES: The positioning of secukinumab in the treatment of axial SpA (axSpA) and PsA is debated, partly due to a limited understanding of the comparative safety of the available treatments. We aimed to assess the risk of the key safety outcome infections during treatment with secukinumab and TNF inhibitors (TNFi). METHODS: Patients with SpA and PsA starting secukinumab or TNFi year 2015 through 2018 were identified in four Nordic rheumatology registers. The first hospitalized infection during the first year of treatment was identified through linkage to national registers. Incidence rates (IRs) with 95% CIs per 100 patient-years were calculated. Adjusted hazard ratios were estimated through Cox regression, with secukinumab as the reference. Several sensitivity analyses were performed to investigate confounding by indication. RESULTS: Among 7708 patients with SpA and 5760 patients with PsA, we identified 16 229 treatment courses of TNFi (53% bionaïve) and 1948 with secukinumab (11% bionaïve). For secukinumab, the first-year risk of hospitalized infection was 3.5% (IR 5.0; 3.9-6.3), compared with 1.7% (IR 2.3; 1.7-3.0) during 3201 courses with adalimumab, with the IRs for other TNFi lying in between these values. The adjusted HR for adalimumab, compared with secukinumab, was 0.58 (0.39-0.85). In sensitivity analyses, the difference from secukinumab was somewhat attenuated and in some analyses no longer statistically significant. CONCLUSION: When used according to clinical practice in the Nordic countries, the observed first-year absolute risk of hospitalized infection was doubled for secukinumab compared with adalimumab. This excess risk seemed largely explained by confounding by indication.

Epidemiology and clinical characteristics of psoriatic arthritis-related uveitis in Madrid, Spain.

PURPOSE: To describe the epidemiology and clinical characteristics of psoriatic arthritis (PsA) related uveitis in Madrid, Spain. METHODS: A case series nested in a retrospective single-center cohort of 494 patients with PsA was performed. Patients older than 18 years old whit a clinical diagnosis PsA-related uveitis who attended the Ramon y Cajal University Hospital in Madrid, Spain, between 1st January 2017 and 31st December 2019 were included in the study. Epidemiological and clinical data were retrieved from the electronic medical records. RESULTS: Thirteen cases of psoriatic arthritis-related uveitis (6 men and 7 women) were included. PsA-related uveitis showed an incidence of 0.05 cases per 100,000 persons/year (CI95 0.00-0.35), and a prevalence of 2.19 cases per 100,000 persons (CI95 1.24-3.79). The prevalence of active uveitis in the cohort of PsA patients was 2.6%. The first episode of uveitis (mean age of 48.15 ± 15.41 years) was anterior and unilateral in 92.31% of the cases. Most of the patients had a recurrent course (69.2%) with 0.92 flare-ups per patient/year (CI95 0.85-0.96). The uveitis preceded the diagnosis of psoriatic arthritis in 62.5% of the patients. In patients with PsA-related uveitis, HLA-B27 was present in 23.1%, HLA-Cw6 in 7.7%. CONCLUSIONS: Uveitis is a PsA manifestation that affects roughly 1 in 37 PsA patients, and that may precede the articular symptoms. It generally presents as a unilateral acute anterior uveitis and has a recurrent course. The most frequent observed complications are elevated intraocular pressure and cataracts.

Active tuberculosis infection in moroccan patients with rheumatic diseases under biologic therapy: A multicenter national study.

Background: The aim of this study was to evaluate the prevalence of active tuberculosis (TB) infection in Moroccan patients with rheumatic diseases under biologic therapy, and to describe the demographic characteristics of these patients as well as to explore potential risk factors. Methods: This 14-year nationally representative multicenter study enrolled Moroccan patients with rheumatic diseases who had been treated with biologic therapy. Patient medical records were reviewed retrospectively for demographic characteristics, underlying rheumatic diseases, associated comorbidities, and TB-related data. Results: In total, 1407 eligible patients were studied, detailed records were obtained for only 130 patients; 33 cases with active TB were identified at an estimated prevalence rate of 2.3%. The mean age was 42.9 ± 12 years and 75.8% were males. Ankylosing spondylitis accounted for 84.8% of active TB cases, and the majority of the cases (31/33) occurred among antitumor necrosis factor-alpha (TNF-α) users. A total of 8 out of 33 patients were positive at initial latent TB infection (LTBI) screening by tuberculin skin test and/or interferon-gamma release assay. Consumption of unpasteurized dairy products (odds ratio [OR], 34.841; 95% confidence interval [CI], 3.1-389.7; P = 0.04), diabetes (OR, 38.468; 95% CI, 1.6-878.3; P = 0,022), smoking (OR, 3.941; 95% CI, 1-159.9; P = 0.047), and long biologic therapy duration (OR, 1.991; 95% CI, 1.4-16.3; P = 0.001) were identified as risk factors for developing active TB. Conclusion: Moroccan patients with rheumatic diseases under anti-TNF-α agents are at an increased TB risk, especially when risk factors are present. Strict initial screening and regular monitoring of LTBI is recommended for patients living in high TB prevalence areas.

Spondyloarthritis in familial Mediterranean fever: a cohort study.

Familial Mediterranean fever (FMF) and spondyloarthritis (SpA) may show several common signs. This study aimed to evaluate the frequency of SpA and its manifestations in FMF, the impact of SpA on FMF, and the associations of non-episodic findings (heel enthesitis, protracted arthritis, and sacroiliitis) with the FMF features. Demographic, clinical, imaging, and genetic data were retrieved from medical records of the patients with adult FMF. To identify patients who met the classification criteria for SpA, data including rheumatologic inquiry were recorded. Patients with SpA and those who did not meet the criteria were compared in terms of FMF features. Regression analyses were performed to determine the factors that were most associated with sacroiliitis, enthesitis, and protracted arthritis. Of the 283 patients with FMF, 74 (26.1%) met the SpA criteria (64 axial, 10 peripheral); and 65 (22.9%) patients had sacroiliitis, 27 (9.5%) protracted arthritis, and 61 (21.6%) heel enthesitis. Patients with SpA were older and had more FMF severity, and heel pain rate than those without; however, genetic features, CRP, resistance to colchicine, and heel enthesitis did not differ. A meaningful number of patients without SpA had also displayed heel enthesitis, protracted arthritis, inflammatory back pain, heel pain, family history of SpA, and elevated CRP. Age was found to be the main predictor of heel enthesitis and protracted arthritis was linked with FMF severity. A significant number of patients with FMF meet the peripheral SpA classification criteria as well as axial SpA. SpA and its shared manifestations with FMF may have an impact on FMF.

Detailed bone assessment of the sacroiliac joint in a prospective imaging study: comparison between computed tomography, zero echo time, and black bone magnetic resonance imaging.

OBJECTIVES: To compare the value of zero echo time (ZTE) and gradient echo "black bone" (BB) MRI sequences for bone assessment of the sacroiliac joint (SI) using computed tomography (CT) as the reference standard. MATERIALS AND METHODS: Between May 2019 and January 2021, 79 patients prospectively underwent clinically indicated 3-T MRI including ZTE and BB imaging. Additionally, all patients underwent a CT scan covering the SI joints within 12 months of the MRI examination. Two blinded readers performed bone assessment by grading each side of each SI joint qualitatively in terms of seven features (osteophytes, subchondral sclerosis, erosions, ankylosis, joint irregularity, joint widening, and gas in the SI joint) using a 4-point Likert scale (0 = no changes-3 = marked changes). Scores were compared between all three imaging modalities. RESULTS: Interreader agreement was largely good (k values: 0.5-0.83). Except for the feature "gas in SI joint" where ZTE exhibited significantly lower scores than CT (p < 0.001), ZTE and BB showed similar performance relative to CT for all other features (p > 0.52) with inter-modality agreement being substantial to almost perfect (Krippendorff's alpha coefficients: 0.724-0.983). When combining the data from all features except for gas in the SI joint and when binarizing grading scores, combined sensitivity/specificity was 76.7%/98.6% for ZTE and 80.8%/99.1% for BB, respectively, compared to CT. CONCLUSIONS: The performance of ZTE and BB sequences was comparable to CT for bone assessment of the SI joint. These sequences may potentially serve as an alternative to CT yet without involving exposure to ionizing radiation.

Implementation of the OMERACT Psoriatic Arthritis Magnetic Resonance Imaging Scoring System in a randomized phase IIb study of abatacept in psoriatic arthritis.

OBJECTIVES: To investigate if the OMERACT PsA MRI Scoring System (PsAMRIS), including a novel total inflammation score, shows sensitivity to change with an agent (abatacept) known to impact clinical outcomes in PsA. METHODS: We performed a post hoc analysis of a randomized phase IIb study of abatacept in patients with PsA and inadequate DMARD response. Participants received one of three abatacept dosing regimens [ABA3, ABA10 or ABA30/10 mg/kg (30 mg/kg switched to 10 mg/kg after two doses)] or placebo until day 169, then ABA10 through day 365. MRIs at baseline and days 85, 169 and 365 were centrally evaluated by two readers blinded to chronological order and treatment arm. Synovitis, osteitis, tenosynovitis, periarticular inflammation, bone erosions, joint space narrowing and bone proliferation were assessed using the PsAMRIS. A novel total inflammation score was tested. RESULTS: MRIs for 123 patients were included. On day 169, ABA10 and ABA30/10 significantly reduced MRI synovitis and tenosynovitis, respectively, vs placebo [differences -0.966 (P = 0.039) and -1.652 (P = 0.014), respectively]. Synovitis in the placebo group increased non-significantly from baseline to day 169, total inflammation and tenosynovitis decreased non-significantly and all measures improved significantly after a switch to ABA10 [-1.019, -0.940, -2.275 (P < 0.05), respectively, day 365 vs day 169]. Structural outcomes changed minimally across groups. CONCLUSION: Adults with PsA receiving ABA10 and ABA30/10 demonstrated significant resolution of inflammatory components of disease, confirmed by MRI, with synovitis and tenosynovitis improvements consistent with previously reported clinical responses for these doses. Results indicate that a reduction in OMERACT PsAMRIS inflammation scores may provide proof of tissue-level efficacy in PsA clinical trials.

High Prevalence of Previously Undiagnosed Axial Spondyloarthritis in Patients Referred With Anterior Uveitis and Chronic Back Pain: The SpEYE Study.

OBJECTIVE: To reduce the diagnostic delay in axial spondyloarthritis (axSpA), guidelines recommend referring patients with acute anterior uveitis (AAU) and chronic back pain (CBP) to a rheumatologist. This observational study in daily practice evaluated the prevalence of previously unrecognized axSpA in patients with AAU who were referred by ophthalmologists because of concurrent CBP. METHODS: All patients with AAU referred with CBP (≥ 3 months, age of onset < 45 yrs) from 5 ophthalmology clinics underwent rheumatologic assessment, including pelvic radiographs. Patients with previously diagnosed rheumatic disease and AAU due to other causes were excluded. The primary endpoint was a clinical axSpA diagnosis by the rheumatologist. RESULTS: Eighty-one patients fulfilled the referral criteria (52% male, 56% HLA-B27 positive, median age 41 yrs, median CBP duration 10 yrs). In total, 58% (n = 47) had recurring AAU, of whom 87% already had CBP during previous AAU attacks. After assessment, 23% (n = 19) of patients were clinically diagnosed with definite axSpA (10/19 radiographic), 40% (n = 32) with suspicion of axSpA, and 37% (n = 30) with no axSpA. AxSpA was diagnosed more often in men (33% of the men vs 13% of the women). CONCLUSION: A high prevalence of axSpA was found in patients with AAU referred because of CBP. There was substantial diagnostic delay in the majority of patients with recurring AAU, as many already had CBP during previous AAU flares. In AAU, screening for CBP and prompt referral has a high diagnostic yield and should consistently be promoted among ophthalmologists.

The effects of autoimmune rheumatic-related diseases on male reproductive health: A systematic review.

Autoimmune rheumatic-related diseases (ARRDs) have physical and psychological impact on patients, including their sexual life. While many studies have investigated fertility problems in females, data on males-related fertility are scarce, which explains the lack of guidance. The main objective of this systematic review was to evaluate the reproductive health in males with ARRDs. This systematic review followed the preferred reporting items for systematic reviews guidelines. Original articles from Pubmed and Scopus, published until September 16, 2021, and tackling the effects of ARRDs and/or ARRDs treatments on male fertility and/or pregnancy outcomes, were included. A total of twenty-five studies met the inclusion criteria. They were published between 1981 and 2018. The studied ARRDs were spondyloarthritis (n = 9), systematic lupus erythematosus (SLE, n = 6), Behcet disease (BD, n = 5), rheumatoid arthritis (RA, n = 5), antiphospholipid syndrome (n = 1), and dermatomyositis (n = 1). The most reported effects of ARRDs on fertility are i) high levels of reproductive hormones, mainly in RA and SLE; ii) impaired semen quality in SLE, spondyloarthritis, and BD; and iii) higher rate of varicocele in BD and spondyloarthritis. Regarding the treatments effects, i) conventional synthetic disease-modifying anti-rheumatic drugs (e.g.; methotrexate and salazopyrine) increase testosterone level, ii) cyclophosphamide impairs fertility, iii) anti-tumor necrosis factor agents are associated with improvement in semen quality, and iv) no increased number of miscarriages or congenital abnormalities in children fathered by BD was reported. To conclude, both ARRDs and their treatments alter fertility in males with ARRDs. In practice, in addition to the conventional semen analysis, screening for infertility seems legitimate in males with ARRDs.

Risk of flare after tapering or withdrawal of biologic/targeted synthetic disease-modifying anti-rheumatic drugs in patients with rheumatoid arthritis or axial spondyloarthritis: a systematic review and meta-analysis.

OBJECTIVE: To evaluate flare risk when tapering or withdrawing biologic or targeted synthetic DMARDs (bDMARDs or tsDMARDs) compared with continuation in patients with inflammatory arthritis in sustained remission or with low disease activity. METHODS: Articles were identified in the Cochrane Library, PubMed, Embase and Web of Science. Eligible trials were randomized controlled trials comparing tapering and/or withdrawal of bDMARDs and/or tsDMARDs with the standard dose in inflammatory arthritis. Random effects meta-analysis was performed with risk ratio (RR) or Peto's odds ratio (POR) for sparse events and 95% CI. RESULTS: The meta-analysis comprised 22 trials: 11 assessed tapering and 7 addressed withdrawal (4 assessed both). Only trials with an RA or axial SpA (axSpA) population were identified. An increased flare risk was demonstrated when b-/tsDMARD tapering was compared with continuation [RR 1.45 (95% CI 1.19, 1.77), I2 = 42.5%] and potentially increased for persistent flare [POR 1.56 (95% CI 0.97, 2.52), I2 = 0%]. Comparing TNF inhibitor (TNFi) withdrawal with continuation, a highly increased flare risk [RR 2.28 (95% CI 1.78, 2.93), I2 = 78%] and increased odds of persistent flare [POR 3.41 (95% CI 1.91, 6.09), I2 = 49%] were observed. No clear difference in flare risk between RA or axSpA was observed. CONCLUSION: A high risk for flare and persistent flare was demonstrated for TNFi withdrawal, whereas an increased risk for flare but not for persistent flare was observed for b-/tsDMARD tapering. Thus tapering seems to be the more favourable approach. REGISTRATION: PROSPERO (CRD42019136905).

Apremilast monotherapy for long-term treatment of active psoriatic arthritis in DMARD-naïve patients.

OBJECTIVES: Apremilast monotherapy was evaluated up to 5 years in PALACE 4 (fourth PsA Long-term Assessment of Clinical Efficacy study) DMARD-naïve patients with PsA. METHODS: Patients with active PsA were randomized (1:1:1) to placebo, apremilast 30 mg or apremilast 20 mg twice a day. Placebo patients were rerandomized to apremilast at week 16 or 24. Double-blind apremilast continued to week 52, with a 4-year open-label extension (≤260 weeks of exposure). Analyses through week 260 were based on observed data. RESULTS: A total of 527 patients were treated. Among patients randomized to apremilast 30 mg at baseline, 45.5% completed week 260. At study end, 24.8% reported conventional synthetic DMARD or steroid use for any reason. At week 260, 65.8%/39.0%/20.3% of apremilast 30 mg patients achieved ACR20/ACR50/ACR70 responses, respectively. PsA sign and symptom improvements were sustained up to week 260 with continued treatment, including reductions in swollen (84.8%) and tender (76.4%) joint counts. Among apremilast 30 mg patients with baseline enthesitis or dactylitis, 71.2% achieved a Maastricht Ankylosing Spondylitis Enthesitis Score of 0 and 95.1% achieved a dactylitis count of 0. Over 50% of patients achieved a HAQ Disability Index minimal clinically important difference (≥0.35). In patients with ≥3% baseline psoriasis-involved body surface area, 60.3% and 47.6% achieved ≥50% and ≥75% improvement in Psoriasis Area and Severity Index scores, respectively. Patients continuing apremilast 20 mg also demonstrated consistent, sustained improvements. The most common adverse events were diarrhoea, nausea, headache, upper respiratory tract infection and nasopharyngitis. No new safety concerns were observed long term. CONCLUSIONS: Apremilast led to sustained PsA efficacy up to 260 weeks and was well tolerated. TRIAL REGISTRATION: ClinicalTrials.gov (http://clinicaltrials.gov), NCT01307423.

Fertility and pregnancy outcomes in women with spondyloarthritis: a systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to determine the impact of SpA and its treatments on fertility and pregnancy outcomes, as well as the impact of pregnancy on disease activity. METHODS: A systematic review and meta-analyses were performed, including studies in women with SpA [axial (axSpA) and peripheral SpA, including PsA]. The heterogeneity between studies was quantified (I2), and in the case of substantial heterogeneity, the results were reported in a narrative review. RESULTS: Of 4397 eligible studies, 21 articles were included, assessing a total of 3566 patients and 3718 pregnancies, compared with 42 264 controls. There is a lack of data on fertility in the literature. We found an increased risk of preterm birth [pooled odds ratio (OR) 1.64 (1.15-2.33), I2 =24% in axSpA and 1.62 (1.23-2.15), I2 =0.0% in PsA], small for gestational age [pooled OR 2.05 (1.09-3.89), I2 =5.8% in axSpA], preeclampsia [pooled OR 1.59 (1.11-2.27], I2 =0% in axSpA] and caesarean section [pooled OR 1.70 (1.44-2.00), I2 =19.9% in axSpA and 1.71 (1.14-2.55), I2 =74.3% in PsA], without any other unfavourable pregnancy outcome. Further analysis showed a significantly higher risk of elective caesarean section [pooled OR 2.64 (1.92-3.62), I2 =0.0% in axSpA and 1.47 [1.15-1.88], I2 =0,0% in PsA), without increased risk of emergency caesarean section in PsA. During pregnancy, there appears to be a tendency for unchanged or worsened disease activity in axSpA and unchanged or improved disease activity in PsA. Both conditions tend to flare in the postpartum period. CONCLUSION: SpA seems to be associated with an increased risk of preterm birth, small for gestational age, preeclampsia, and caesarean section.

Is pain associated with premature mortality in patients with psoriatic arthritis? A nested case-control study using the DANBIO Register.

OBJECTIVES: It has been hypothesized that the presence of chronic pain causes excess mortality. Since chronic pain is prevalent among patients with PsA this potential association should be explored. We aimed to investigate whether higher cumulative pain intensity is associated with an excess mortality risk in patients with PsA. METHODS: A nested case-control study using data from the nationwide DANBIO Register (Danish Database for Biological Therapies in Rheumatology) Register and Danish healthcare registers. Cases were patients who died and corresponding to the date of death, matched on sex, year of birth and calendar period at the time of death with up to five controls. Exposure of interest was mean pain intensity reported during the time followed in routine rheumatology practice. Pain intensity was measured using a visual analogue scale from 0 to 100 and conditional logistic regression was used to calculate odds of mortality per 5 unit increase in pain while adjusting for confounders. RESULTS: The cohort consisted of 8019 patients. A total of 276 cases were identified and matched with 1187 controls. Higher mean pain intensity was associated with increased odds of mortality [odds ratio 1.06 (95% CI 1.02, 1.10)] in the crude model, but there was no association [odds ratio 0.99 (95% CI 0.95, 1.03)] when adjusting for additional confounders. Factors shown to increase the odds of mortality were recent glucocorticoid use, concomitant chronic obstructive pulmonary disease, diabetes mellitus, cancer and cardiovascular disease. CONCLUSION: These results indicate that experienced pain in itself is not associated with premature mortality in patients with PsA. However, recent glucocorticoid use and concurrent comorbidities were.

Diagnostic performance of plain radiography for sacroiliitis in patients with suspected axial spondyloarthritis: a systematic review and meta-analysis.

BACKGROUND: Plain radiography serves a pivotal role in diagnosing axial spondyloarthritis. However, a broad range of diagnostic performance of plain radiography has been reported. PURPOSE: To perform a systematic review and meta-analysis to measure the diagnostic performance of plain radiography for sacroiliitis in patients suspected of having axial spondyloarthritis using magnetic resonance imaging (MRI) findings as the reference standard. MATERIAL AND METHODS: Studies comparing radiography and MRI in the diagnosis of sacroiliitis in patients suspected of having axial spondyloarthritis were searched in PubMed and EMBASE. Additionally, studies analyzed SPondyloaArthritis Caught Early (SPACE), DEvenir des Spondylarthropathies Indifferenciées Récentes (DESIR), GErman Spondyloarthritis Inception Cohort (GESPIC), and South Swedish Arthritis Treatment Group (SSATG) cohorts were manually searched. Pooled sensitivity and specificity of radiography were calculated by using a bivariate random-effects model. Meta-regression analyses were performed to identify the sources of heterogeneity. RESULTS: Eight eligible studies with 1579 patients were included. The pooled sensitivity and specificity of radiography were 0.55 (95% confidence interval [CI] = 0.40-0.69) and 0.87 (95% CI = 0.72-0.95). The meta-regression analyses showed prospective study design and criteria for MRI positivity considering only active bone marrow edema were associated with lower sensitivity. CONCLUSION: The plain radiography showed low sensitivity and reasonable specificity in diagnosis of sacroiliitis in patients suspected of having axial spondyloarthritis.

The risks of major cardiac events among patients with psoriatic arthritis treated with apremilast, biologics, DMARDs or corticosteroids.

OBJECTIVES: People with PsA are at increased risk of cardiovascular disease. The objective of this study was to quantify the risk of myocardial infarction (MI), stroke and revascularizations in people with apremilast-treated PsA compared with patients receiving other PsA treatments. METHODS: We conducted a cohort study of 68 678 patients with PsA treated with apremilast, TNF inhibitor (TNF-i) biologics, IL-17 or -12/23 biologics, conventional DMARDs or CS in the United States MarketScan database. Cohort entry was date of first study drug after 21 March 2014. Cases were patients with MI, stroke or revascularization. We calculated incidence rates (IRs) and incidence rate ratios for each outcome by exposure. RESULTS: We identified 292 MI, 151 stroke and 475 revascularizations cases. IRs for MI were lowest for users of TNF-i biologics [1.4 per 1000 person-years (PY)] and similar for all other treatments, including apremilast, ranging from 1.8 to 3.8 per 1000 PY. IRs were similar for all treatments for both stroke (0.1-1.6 per 1000 PY) and revascularization (3.1-5.1 per 1000 PY). IRs for apremilast were 2.5 per 1000 PY for MI, 1.6 per 1000 PY for stroke and 3.3 per 1000 PY for revascularization. CONCLUSION: In patients with treated PsA, IRs of MI, stroke and revascularization were low for all systemic treatments evaluated. Although the number of events was small, apremilast exposure did not signal potential acute cardiovascular harm and was not associated with a material increase in the risk of these serious cardiac events.

Secukinumab provides sustained low rates of radiographic progression in psoriatic arthritis: 52-week results from a phase 3 study, FUTURE 5.

OBJECTIVE: To evaluate the effect of secukinumab on radiographic progression through 52 weeks in patients with PsA from the FUTURE 5 study. METHODS: Patients with active PsA, stratified by prior anti-TNF use (naïve or inadequate response), were randomized to s.c. secukinumab 300 mg load (300 mg), 150 mg load (150 mg), 150 mg no load regimens or placebo at baseline, at weeks 1, 2 and 3 and every 4 weeks starting at week 4. Radiographic progression was assessed by change in van der Heijde-modified total Sharp score (vdH-mTSS; mean of two readers). Statistical analysis used a linear mixed-effects model (random slope) at weeks 24 and 52, and observed data at week 52. Assessments at week 52 included additional efficacy endpoints (non-responders imputation and mixed-effects models for repeated measures) and safety. RESULTS: The majority (86.6%) of patients completed 52 weeks of treatment. The proportion of patients with no radiographic progression (change from baseline in vdH-mTSS ⩽0.5) was 91.8, 85.2 and 87.2% in 300, 150 and 150 mg no load groups, respectively, at week 52. The change in vdH-mTSS from baseline to week 52 using random slope [mean change (s.e.)] was -0.18 (0.17), 0.11 (0.18) and -0.20 (0.18) in 300, 150 and 150 mg no load groups, respectively; the corresponding observed data [mean change (s.d.)] was -0.09 (1.02), 0.13 (1.39) and 0.21 (1.15). Clinical efficacy endpoints were sustained, and no new or unexpected safety signals were reported through 52 weeks. CONCLUSION: Secukinumab 300 and 150 mg with or without s.c. loading regimen provided sustained low rates of radiographic progression through 52 weeks of treatment.

Echocardiographic Evaluation of Axial Spondyloarthritis in Korea: Data From the Catholic Axial Spondyloarthritis Cohort

OBJECTIVE: Axial spondyloarthritis (axSpA) is often accompanied by cardiac manifestations, such as valvular heart disease. In this prospective cohort study, we evaluated the incidence of cardiac abnormalities in Korean axSpA patients by echocardiography.METHODS: AxSpA patients were prospectively recruited from a single tertiary hospital. Baseline demographic, clinical, radiographic, and echocardiographic data were collected at the time of enrollment. Echocardiography evaluations were performed with a focus on valvular heart disease and systolic and diastolic function. Logistic regression analyses were used to identify factors associated with diastolic dysfunction in axSpA.RESULTS: A total of 357 axSpA patients were included in the analyses, of whom 78 (21.8%) exhibited diastolic dysfunction, with no reports of systolic dysfunction. Thirteen patients (3.6%) had valvular heart disease, and aortic valve regurgitation (n=5) and mitral valve regurgitation (n=6) were most common. Multivariable logistic regression analyses indicated that older age and higher body mass index (BMI) were positively associated with diastolic dysfunction, whereas human leukocyte antigen (HLA)-B27 positivity was negatively associated with diastolic dysfunction.CONCLUSION: Valvular heart disease is infrequent in Korean axSpA patients. However, diastolic dysfunction is common in axSpA patients, and is significantly associated with older age, higher BMI, and HLA-B27.

Evaluation of Mobile Apps Targeted at Patients With Spondyloarthritis for Disease Monitoring: Systematic App Search.

BACKGROUND: There are many apps developed for patients with spondyloarthritis in the market, but their purpose and quality are not objectively evaluated. OBJECTIVE: The objective of this study was to identify and evaluate existing publicly available, high-quality apps that use validated measurement instruments for monitoring spondyloarthritis disease activity. METHODS: We conducted a review of apps available on the Apple App Store and the Google Play Store based on a combination of keywords and inclusion and exclusion criteria. Validated disease activity measurement instruments were identified. Data regarding app characteristics, including the presence of validated disease activity measurement, were extracted. The Mobile App Rating Scale (MARS) was used to review the apps for user experience. RESULTS: A total of 1253 apps were identified in the app stores, and 5 apps met the criteria and were further analyzed. Moreover, 2 apps (MySpA and Group for Research and Assessment of Psoriasis and Psoriatic Arthritis App) contained some of the validated disease activity monitoring instruments for specific spondyloarthritis subtypes. These 2 apps were also rated good on the MARS (with total mean scores ≥4 out of 5), whereas the other apps scored poorly in comparison. CONCLUSIONS: There are 2 high-quality spondyloarthritis disease activity monitoring apps publicly available, but they only target 2 spondyloarthritis subtypes-ankylosing spondylitis and psoriatic arthritis. There is a lack of high-quality apps that can measure disease activity for other spondyloarthritis subtypes, and no app that consolidates all validated disease activity instruments across subtypes was available.
