Patients with radiographic axial spondylarthritis have an impaired dietary intake-a cross-sectional study with matched controls from northern Sweden.

BACKGROUND: Radiographic axial spondyloarthritis (r-axSpA) is one of the most common chronic inflammatory rheumatic diseases, affecting about 0.2% of the Swedish population. Adequate nutritional intake is essential for maintaining physiological functions. A poor diet increases the risk of developing conditions such as obesity, osteoporosis, and/or atherosclerosis. Diet quality is also theorized to affect systemic inflammation. Dietary habits in patients with r-axSpA are largely unknown. The aims of this study were to assess dietary nutrient intake in r-axSpA patients and examine whether it differs compared to persons without r-axSpA. METHODS: r-axSpA patients (modified NY criteria) at the rheumatology clinic in Region Västerbotten, northern Sweden, were invited to take part in the Backbone study which investigates disease severity and comorbidities. In total, 155 patients were included. Nutritional intake was assessed by the semi-quantitative food frequency questionnaire MiniMeal-Q. Controls were collected from the Swedish CArdioPulmonary bioImage Study (n = 30,154), a study that invited participants 50-64 years of age by random selection from the Swedish population register. Out of the 155 r-axSpA patients, 81 were in the same age span. Four controls were identified for each patient, matched on age (± 1 year), sex, and geographic location. Data on dietary intake was available for 319 controls. Statistical comparisons of dietary intake between patients with r-axSpA and controls were done by exact conditional logistic regression analysis, adjusted for country of birth, educational level, single household, weight, smoking status, and energy intake. RESULTS: Patients had a comparatively significantly higher energy intake from carbohydrates, a lower fiber density, and a lower intake of marine omega-3 fatty acids. Furthermore, intake of vitamins D, E, and K as well as selenium, folate, calcium, magnesium, phosphorus, potassium, vitamin A, and ß-carotene (a precursor of vitamin A and marker of vegetable and fruit intake) was significantly lower among patients compared to controls. CONCLUSIONS: Our results suggest that r-axSpA patients have an impaired dietary intake. Notably, intake was lower in several nutrients theorized to have anti-inflammatory properties (fiber density, marine-omega-3 fatty acids, vitamin D, and selenium). We further propose that nutrition screening might be incorporated into the management of r-axSpA patients.

Sleep behaviour differs in women and men with psoriatic arthritis and axial spondyloarthritis with impact on quality of life and depressive symptoms.

OBJECTIVES: Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) may have a profound impact on sleep and health-related quality of life. The aim of this study was to assess sleep quality and quality of life and determine associated factors in patients treated with spondyloarthritides (SpA). METHODS: Cross-sectional questionnaire-based assessment of sleep behaviour, quality of life, functional impairment and depression (Regensburg Insomnia Scale, WHO Quality of Life questionnaire, Funktionsfragebogen Hannover questionnaire, Beck Depression Inventory II, Patient health questionnaire 9) and retrospective medical chart analysis of a monocentric cohort of 330 patients with SpA (n=168 PsA and n=162 axSpA). RESULTS: 46.6% of patients with SpA demonstrated abnormal sleep behaviour. Linear regression models showed HLA-B27 positivity, Bath Ankylosing Spondylitis Disease Activity Index, depressive symptoms, functional capacity and disease duration to be predictive of insomnia symptoms in axSpA, respectively, depressive symptoms, female sex and Disease Activity Score 28 in patients with PsA. Patients with unrestful sleep had a significantly reduced health-related quality of life (p<0.001) as well as significantly more depressive symptoms (p<0.001). Satisfaction with health was rated significantly lower (p<0.001), indicating poor sleep as a burden on general well-being.In particular, female patients had a significantly worse sleep quality with a prolonged sleep latency (p=0.009), increased sleep disturbances (p=0.014) and unrestful sleep (p<0.001) as well as a reduced physical and mental health-related quality of life (p=0.015, p<0.001) and more depressive symptoms (p=0.015). CONCLUSION: Despite treatment, many patients with SpA demonstrate abnormal sleep behaviour with symptoms of insomnia and a reduced quality of life with significant differences between male and female patients. An interdisciplinary and holistic approach may be needed to address unmet needs.

Multidisciplinary Team Led by Joint Surgeons to Rapidly Identify Spondyloarthritis.

Context: Spondyloarthritis (SpA) is a group of chronic, inflammatory, rheumatic diseases of which axial SpA and peripheral SpA are the two main types. Patients that predominantly have manifestations of axSpA may have additional peripheral-arthritis symptoms, and vice versa. For these hard-to-diagnose SpA patients, symptoms can be nonspecific and difficult to identify, making it easy to miss a diagnosis or misdiagnosis patients, resulting in disability. Objective: The study intended to evaluate the value of a multidisciplinary team (MDT) led by the joint surgeons to rapidly identify spondyloarthritis (SpA). Design: The research team designed a controlled study that analyzed the clinical data of patients with spondyloarthritis. Setting: The study was conducted in the Department of Joint Surgery at Shandong Second Provincial General Hospital in Jinan, China. Participants: Participants were 113 SpA patients at the hospital between January 2019 and January 2020. Intervention: he research team divided participants into an intervention group, the MDT group that used that model to diagnose 83 participants and the control group with 30 participants, for whom diagnoses occurred using the conventional diagnostic model. Outcome Measures: The research team collected data on participants' number of visits and number of departments visited as well as determined the amount of time that elapsed before a diagnosis occurred. The team also measured C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) and the scores on the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Bath Ankylosing Spondylitis Functional Index (BASFI) at baseline and after 3 months and 6 months treatment. Results: In the MDT group, diagnoses included: (1) axial SpA (axSpA)-73 participants, and (2) peripheral SpA-10 participants, including three with reactive arthritis, two with uveitis, and five with psoriatic arthritis. Eight participants in that group were HLA-B27 positive, and 14 had complications from a latent tuberculosis infection. In the control group, diagnoses included: (1) axSpA-25 participants; and (2) peripheral SpA-5 participants, including three with psoriatic arthritis and two with reactive arthritis. Six participants in that group were HLA-B27 positive and four had complications from a latent tuberculosis infection. The number of visits, number of departments visited, and time to diagnosis in the MDT group were significantly lower than those in the control group (P < .001). After three and six months of treatment, the MDT group's CRP, ESR, BASDAI, and BASFI were significantly lower than those at baseline (P < .001). Conclusions: The MDT model of spondyloarthritis led by joint surgeons was accurate and efficient, allowing the medical personnel to quickly identify and intervene in SpA and provide effective treatment for patients. It's a diagnosis and treatment model worthy of promotion.

Dual Blockade of TNF and IL-17A Inhibits Inflammation and Structural Damage in a Rat Model of Spondyloarthritis.

The tumor necrosis factor (TNF) and IL-23/IL-17 axes are the main therapeutic targets in spondyloarthritis. Despite the clinical efficacy of blocking either pathway, monotherapy does not induce remission in all patients and its effect on new bone formation remains unclear. We aimed to study the effect of TNF and IL-17A dual inhibition on clinical disease and structural damage using the HLA-B27/human ß2-microglobulin transgenic rat model of SpA. Immunized rats were randomized according to arthritis severity, 1 week after arthritis incidence reached 50%, to be treated twice weekly for a period of 5 weeks with either a dual blockade therapy of an anti-TNF antibody and an anti-IL-17A antibody, a single therapy of either antibody, or PBS as vehicle control. Treatment-blinded observers assessed inflammation and structural damage clinically, histologically and by micro-CT imaging. Both single therapies as well as TNF and IL-17A dual blockade therapy reduced clinical spondylitis and peripheral arthritis effectively and similarly. Clinical improvement was confirmed for all treatments by a reduction of histological inflammation and pannus formation (p < 0.05) at the caudal spine. All treatments showed an improvement of structural changes at the axial and peripheral joints on micro-CT imaging, with a significant decrease for roughness (p < 0.05), which reflects both erosion and new bone formation, at the level of the caudal spine. The effect of dual blockade therapy on new bone formation was more prominent at the axial than the peripheral level. Collectively, our study showed that dual blockade therapy significantly reduces inflammation and structural changes, including new bone formation. However, we could not confirm a more pronounced effect of dual inhibition compared to single inhibition.

Axial Spondyloarthritis in the Chiropractic Care Setting: A Systematic Literature Review.

ABSTRACT: Diagnosis of axial spondyloarthritis (axSpA), an immune-mediated inflammatory disease, is commonly associated with chronic inflammatory back pain (IBP) and often occurs years after initial onset of clinical symptoms. Recognition of IBP is important for timely referral of patients with suspected axSpA to a rheumatologist. Patients with all types of back pain are treated in chiropractic care, but the proportion of patients with undiagnosed axSpA is unknown. This systematic literature review investigated the presence of axSpA in patients treated by chiropractors and identified the chiropractor's role in axSpA diagnosis, referral, and management. A PubMed search was conducted using the following search strings: "chiropract*" AND ("sacroiliac" OR "back pain" OR "spondyloarthritis" OR "ankylosing spondylitis"); English language, since 2009; and (chiropractic OR chiropractor) AND (ankylosing spondylitis OR axial spondyloarthritis), with no date limits. Of 652 articles identified in the searches, 27 met the inclusion criteria. Although back pain was identified as a common reason for patients seeking chiropractic care, there was no mention of axSpA, ankylosing spondylitis, or the distinction between mechanical and IBP. Data from relevant articles suggested that the majority of patients seeking chiropractic care have lower back pain, whereas no articles reported axSpA in this patient population. The near absence of any identified articles on axSpA in chiropractic care may be due to underrecognition of axSpA, resulting in delayed rheumatology referral and appropriate management. Better awareness and increased use of validated screening tools could reduce diagnostic delay of axSpA in chiropractic care.

Disease activity outcome measures are only available in half of the electronic medical files of patients with axial spondyloarthritis followed in an outpatient clinic: the results of an audit of a tertiary-care rheumatology department.

Current recommendations for management of patients with axial spondyloarthritis (axSpA) include regular collection of validated disease activity outcomes. This study aimed at evaluating the proportion of patients for whom validated outcome measures were available on their electronic medical reports (EMR), and the factors associated with the presence of such information on the EMR. We performed a cross-sectional monocentric observational study, including patients with an axSpA diagnosis who attended an outpatient visit between February, 2018 and February, 2019. Patients (demographics, disease characteristics, treatment) and physician characteristics (age, gender) and the disease activity outcome measures (BASDAI, CRP and ASDAS, and the items allowing to calculate them) were retrieved from the EMR. The proportion of patients in which disease activity outcome measures were available in the EMR was calculated, and the association between the presence of such outcomes and patients and physician's characteristics was evaluated. 320 EMR of axSpA patients seen in the outpatient clinic were examined. Among them, 131 (41%) and 123 (38.4%) had a BASDAI + CRP and an ASDAS reported, respectively, but at least one was available in 178 (55.6%) of the EMR. The most frequently reported disease activity items were duration of morning stiffness (n = 230, 72%) and CRP (n = 224, 70%). Only previous participation on a systematic holistic review was independently associated with a reported disease activity outcome. Thus, implementation of recommendations with regard to regularly collecting disease activity outcome measures is not optimal. The participation in educational programs including self-assessment educational programs might be a key to improve such implementation.

Gender differences in patient journey to diagnosis and disease outcomes: results from the European Map of Axial Spondyloarthritis (EMAS).

INTRODUCTION/OBJECTIVES: To evaluate the journey to diagnosis, disease characteristics and burden of disease in male and female patients with axial spondyloarthritis (axSpA) across Europe. METHOD: Data from 2846 unselected patients participating in the European Map of Axial Spondyloarthritis (EMAS) study through an online survey (2017-2018) across 13 countries were analysed. Sociodemographic characteristics, lifestyle, diagnosis, disease characteristics and patient-reported outcomes (PROs) [disease activity -BASDAI (0-10), spinal stiffness (3-12), functional limitations (0-54) and psychological distress (GHQ-12)] were compared between males and females using chi-square (for categorical variables) and student t (for continuous variables) tests. RESULTS: In total, 1100 (38.7%) males and 1746 (61.3%) females participated in the EMAS. Compared with males, females reported considerable longer diagnostic delay (6.1 ± 7.4 vs 8.2 ± 8.9 years; p < 0.001), higher number of visits to physiotherapists (34.5% vs 49.5%; p < 0.001) and to osteopaths (13.3% vs 24.4%; p < 0.001) before being diagnosed and lower frequency of HLA-B27 carriership (80.2% vs 66.7%; p < 0.001). In addition, females reported higher degree of disease activity in all BASDAI aspects and greater psychological distress through GHQ-12 (4.4 ± 4.2 vs 5.3 ± 4.1; p < 0.001), as well as a greater use of alternative therapies. CONCLUSION: The patient journey to diagnosis of axSpA is much longer and arduous in females, which may be related to physician bias and lower frequency of HLA-B27 carriership. Regarding PROs, females experience higher disease activity and poorer psychological health compared with males. These results reflect specific unmet needs in females with axSpA needing particular attention. Key Points • Healthcare professionals' perception of axSpA as a predominantly male disease may introduce some bias during the diagnosis and management of the disease. However, evidence about male-female differences in axSpA is scarce. • EMAS results highlight how female axSpA patients report longer diagnostic delay and higher burden of the disease in a large sample of 2846 participants of 13 European countries. • Results reflect unmet needs of European female patients. Healthcare professionals should pay close attention in order to accurately diagnose and efficiently manage axSpA cases while further research should be developed on the cause of reported gender differences.

Amongst patients taking biologic therapies for axial spondyloarthritis, which factors are associated with work non-participation?

BACKGROUND: Axial spondyloarthritis (axSpA) frequently presents during working age and therefore impacts work participation. Biologic therapies have demonstrated a positive impact on work-related outcomes in clinical trials but real world data are limited. Therefore, we investigated the prevalence and predictors of work impairment and disability among axSpA patients attending a biologic therapy clinic. METHODS: This was a single-centre, cross-sectional study of patients with axSpA treated with biologic therapy. Work participation was assessed with the Work Productivity and Activity Impairment (WPAI) Questionnaire. Work outcomes (presenteeism, absenteeism, health-related job loss) were compared for gender, time since diagnosis, smoking status and disease outcome measures. RESULTS: Data were available for 165 patients (mean age 47.6 years, 75% male, 21% current smokers). Mean time since diagnosis was 15.5 years and mean duration of biologic therapy 4.7 years; 19/165 (11.5%) were on a tapered-dose regimen. Occupational data were available for 144 patients amongst whom 101 (70.1%) were either currently employed or in full time education. Of those eligible to work, 17/118 (14.4%) reported inability to work due to their axSpA. Amongst those in employment, 10.8% reported absenteeism due to axSpA in the week prior to their clinic visit (mean hours missed = 13). The mean work productivity impairment was 23%. Higher disease activity (BASDAI) and markers of global health, quality of life and pain, (BAS-G, ASQoL and spinal pain VAS) were associated with axSpA related job loss, absenteeism and presenteeism. CONCLUSIONS: In this group of axSpA patients on biologic therapy (mean age 47.6 years), almost 1 in 6 (14.4%) reported axSpA related job loss. Poor work outcomes: axSpA-related work disability, absenteeism and presenteeism were associated with poorer scores for patient-reported disease outcome measures. Strategies for enhancing work productivity should be directed towards those patients at risk of poor work outcomes. More data are needed including details of the types of work that are most difficult with axSpA.

Integrated gastroenterology and rheumatology ambulatory: an innovative approach for enteropathic spondyloarthritis early diagnosis.

Patients with inflammatory bowel disease (IBD) may develop rheumatic diseases, particularly enterophatic spondyloarthritis (ESpA). Similarly, an IBD may develop in patients with SpA. Management of these patients in a dedicated ambulatory could be advantageous. We pioneered an integrated "GastroReumatology" ambulatory where a gastroenterologist and a rheumatologist with a long-lasting expertise in IBD and spondyloarthritis, respectively, simultaneously visit those patients referred for a suspected ESpA. A total of 101 different patients with suspected or known IBD and/or a rheumatic disease were visited. A new diagnosis of ESpA was eventually achieved in 13 (12.9%) patients, and further 12 patients with an already known ESpA were referred for an appropriate management. No cases of IBD in those patients with an established rheumatic disease were observed. Early diagnosis of ESpA is possible in a "GastroReumatology" ambulatory.

[Experiences and results from Rheuma-VOR]. / Erfahrungen und Ergebnisse aus Rheuma-VOR.

Rheumatoid arthritis, psoriatic arthritis and axial spondylarthritis are the most common chronic autoimmune rheumatic diseases. For all three diseases an early diagnosis and initiation of treatment is crucial. The proof of concept network study "Rheuma-VOR" is a further developed version of the predecessor project ADAPTHERA and was extended to several federal states. The aim of this prospective study is to improve the early diagnosis of rheumatoid arthritis, psoriatic arthritis and axial spondylarthritis and thus positively impact the quality of care for patients with the help of multidisciplinary coordinating centers. To date 3710 disease-specific questionnaires from patients with the suspected diagnosis of rheumatoid arthritis, psoriatic arthritis or axial spondylarthritis from 1298 different primary care providers were registered in the multidisciplinary coordination centers. A total of 1958 appointments were made with 1 of the 53 participating rheumatology specialists. In 876 patients, 1 of the 3 rheumatic diseases was diagnosed in an early stage. The waiting period was on average 42.5 days depending on the federal state, which is well below the nationwide average. It should also be noted that the coordinated cooperation and risk stratification of the Rheuma-VOR coordination centers relieved the capacity of rheumatology specialists by 1281 appointments (34.5%). In addition, the 2­week Rheuma Bus Tour and the accompanying initiatives in Rhineland-Palatinate (Rheuma-VOR screening app and the triage consultation) are showing first promising positive results.

Development, usability and acceptability of an integrated eHealth system for spondyloarthritis in the Netherlands (SpA-Net).

Objective: To develop and test the usability and acceptability of a disease-specific integrated electronic health (eHealth) system for spondyloarthritis (SpA) in the Netherlands ('SpA-Net'). Methods: SpA-Net was developed in four phases. First, content and design were discussed with experts on SpA and patients. Second, the database, electronic medical record (EMR) and quality management system were developed. Third, multiple rounds of testing were performed. Fourth, the eHealth system was implemented in practice and feasibility was tested among patients through semistructured focus interviews (n=16 patients) and among care providers through feedback meetings (n=11 rheumatologists/fellows and 5 nurses). Results: After completion of the first three steps of development in 2015, SpA-Net was implemented in 2016. All patients included have a clinical diagnosis of SpA. Information on domains relevant to clinical record-keeping is prospectively collected at routine outpatient consultations and readily available to care providers, presented in a clear dashboard. Patients complete online questionnaires prior to outpatient visits. In February 2019, 1069 patients were enrolled (mean [SD] age 54.9 [14.1] years, 52.4% men). Patients interviewed (n=16) considered SpA-Net an accessible system that was beneficial to disease insight and patient-physician communication, and had additional value to current care. Care providers appreciated the additional information for (preparing) consultations. Barriers were the initial time required to adopt the EMR and the quantity of data entry. Conclusion: SpA-Net enables monitoring of patients with SpA and real-life data collection, and could help improve knowledge and optimise communication between patients and care providers. Both considered SpA-Net a valuable addition to current care. Trial registration number: NTR6740.

Predictive clinical-genetic model of long-term non-response to tumor necrosis factor-alpha inhibitor therapy in spondyloarthritis.

AIM: Tumor necrosis factor inhibitors (TNFi) are effective in controlling disease activity in spondyloarthritis (SpA). However, in a proportion of patients these treatments are ineffective or lead to adverse events. Recently, alternative therapies, such as interleukin (IL)-17 or IL-23 inhibitors, have emerged in the treatment of these pathologies. This study aimed to determine clinical and genetic predictors of non-response to TNFi treatment in 118 spondyloarthritis patients diagnosed according to Assessment in SpondyloArthritis International Society (ASAS) criteria. METHOD: From the literature, 41 single nucleotide polymorphisms (SNPs) were selected that had previously been associated with TNFi treatment response in spondyloarthropathies, rheumatoid arthritis and psoriasis. A clinical non-response was defined as a decrease of <50% of initial Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in axial involvement, or a reduction of less than 1.2 of initial Disease Activity Score of 28 joints-C-reactive protein (DAS28-CRP) in patients with only peripheral involvement. Univariate and multivariate hazard ratios (HR) were determined using Cox proportional hazard models to analyze the potential prognostic factors affecting non-response to TNFi treatment. RESULTS: The clinical factors that significantly increased the non-response rate were: global visual analog scale (VAS), CRP, BASDAI, Bath Ankylosing Spondylitis Functional Index (BASFI), and the number of TNFi used. Only rs11591741 SNP showed an association with non-response. In the multivariate analysis, females had a non-response rate 4.46 times higher than males; each one-point increase in the BASFI index increased the non-response rate by 75%, and being a genotype GG vs GC or CC carrier was associated with an almost 4 times greater non-response rate. CONCLUSION: We developed a clinical-genetic model to identify SpA patients with a long-term non-response to TNFi therapy.

The antiquity of the spondyloarthritides: Presentation of one of the oldest Neolithic cases in Western Europe.

In humans, little is yet known about the origins of the inflammatory rheumatisms of the spondyloarthritides group, especially regarding the period of their emergence. However, a better knowledge of their history would help to clarify their aetiology. We report a paleopathological case of European origin, dated from the late Neolithic (3621-3023 cal BC), consisting of an isolated vertebral block combining erosion, ossification and severe anterior and posterior ankylosis. The lesional presentation is very suggestive of a severe form of axial spondyloarthritis. This specimen and some other rare cases from the same period found in Western Europe suggest that these diseases appeared, in this geographical region, in evolving groups of humans as part of the demographic and epidemiological transition that constituted the Neolithic period. The emergence of infectious agents and the profound dietary changes that occurred during this period of human history may have favoured the appearance of the spondyloarthritides.

Recommendations by the Spanish Society of Rheumatology on the Use of Biological Therapies in Axial Spondyloarthritis. / Recomendaciones de la Sociedad Española de Reumatología sobre el uso de terapias biológicas en espondiloartritis axial.

OBJECTIVE: Recent data published on biological therapy in axial spondyloarthritis (axSpA) since the last publication of the recommendations of the Spanish Society of Rheumatology (SER) has led to the generation of a review of these recommendations based on the best possible evidence. These recommendations should be a reference for rheumatologists and those involved in the treatment of patients with axSpA. METHODS: Recommendations were drawn up following a nominal group methodology and based on systematic reviews. The level of evidence and grade of recommendation were classified according to the model proposed by the Centre for Evidence Based Medicine at Oxford. The level of agreement was established through the Delphi technique. RESULTS: In this review, we did an update of the evaluation of disease activity and treatment objectives. We included the new drugs with approved therapeutic indication for axSpA. We reviewed both the predictive factors of the therapeutic response and progression of radiographic damage. Finally, we drafted some recommendations for the treatment of patients refractory to anti-tumor necrosis factor, as well as for the possible optimization of biological therapy. The document also includes a table of recommendations and a treatment algorithm. CONCLUSIONS: We present an update of the SER recommendations for the use of biological therapy in patients with axSpA.

Adalimumab efficacy in enteropathic spondyloarthritis: A 12-mo observational multidisciplinary study.

AIM: To report adalimumab (Ada) efficacy on articular-gastrointestinal disease and health-related quality of life (HRQoL) in patients with enteropathic spondyloarthritis (ES). METHODS: A cohort of 52 patients with ES was evaluated in the departments of gastroenterology and internal medicine. At baseline, all patients underwent assessment by an integrated gastro-rheumatologic evaluation of articular and gastrointestinal activity, as well patient reported outcomes (PROs) of the HRQoL questionnaires. After this integrated evaluation and following a specific working flowchart, the Ada anti-tumor necrosis factor (TNF)-inhibitor was assigned to a cohort of 30 patients and its clinical efficacy was evaluated at baseline and after 6-mo and 12-mo treatment by the following tests: (1) Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (ASDAS-CRP); Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Metrology Index (BASMI) for articular activity; (2) Inflammatory Bowel Disease Questionnaire (IBDQ), Crohn's Disease Activity Index (CDAI) and partial Mayo (pMayo) score for gastrointestinal symptoms and activity; and (3) Health Assessment Questionnaire (HAQ), Patient Global Assessment (PGA) and Short Form-36 health survey (SF-36) questionnaires for PROs of the HRQoL. RESULTS: Integrated evaluation and management of the patients affected by ES, carried out simultaneously by a gastroenterologist and a rheumatologist, allowed clinicians to choose the optimal therapeutic strategy. In a cohort of 30 ES patients affected by active articular and gastrointestinal disease, or axial active articular inflammation, Ada led to fast and sustained improvement of both articular and gastrointestinal disease activities. In fact, all the clinimetric evaluation tests exploring articular or gastrointestinal activity, as well as all the HRQoL scores, showed a significant improvement having been achieved at the earliest (6-mo) assessment. This important clinical improvement was maintained at the 12-mo follow-up. Importantly, global and gastrointestinal quality of life significantly correlated with articular disease activity, providing evidence to support that the integrated evaluation is the best option to manage patients with ES. CONCLUSION: Ada treatment, upon multidisciplinary (gastro-rheumatologic) evaluation, significantly improves both articular and gastrointestinal inflammation, thereby improving the HRQoL in patients affected by ES.

Vitamin D, disease activity and comorbidities in early spondyloarthritis.

OBJECTIVES: To assess the vitamin D status in patients presenting inflammatory back pain suggestive of axial spondyloarthritis and to assess the relationship between vitamin D status and disease activity/severity; comorbidities at baseline and during the first two years of follow-up. METHODS: DESIR is a prospective, multicentre, observational study. Vitamin D deficiency was defined as <50 nmol/L and severe deficiency less than 25 nmol/L. Clinical variables were collected at each six month interval visits during the two-year follow-up. RESULTS: A total of 700 patients were analysed. The mean vitamin D was 54.2±28.7 nmol/L. Severe deficiency were observed in 11.7% versus 5% in the DESIR cohort versus the French population respectively. In the DESIR cohort, after adjusting for season and ethnicity, vitamin D deficiency remained significantly associated with presence of radiological sacroiliitis, higher ASDAS score and elevated BASDAI. Such association was also found between vitamin D deficiency and the mean value of disease activity/severity parameters during the two-year follow-up. Otherwise, vitamin D deficiency was significantly associated with the presence of baseline abdominal obesity (OR=1.65 [1.05-2.61], p=0.03), low HDL (OR=1.71 [1.14-2.55], p=0.01) and presence of metabolic syndrome (OR=2.20 [1.04-4.64], p=0.03) at baseline. CONCLUSIONS: We found a higher percentage of patients with severe vitamin D deficiency in early axial spondyloarthritis. Vitamin D deficiency was associated with higher disease activity and severity and presence of metabolic syndrome. Further longitudinal studies are required to evaluate the interest of vitamin D supplementation on the long-term outcome of the disease.

Efectos de un programa de ejercicio físico y relajación en el medio acuático en pacientes con espondiloartritis: ensayo clínico aleatorizado / Effects of an exercise and relaxation aquatic program in patients with spondyloarthritis: A randomized trial

Fundamento y objetivo: La espondiloartritis hace referencia a un conjunto de enfermedades reumáticas crónicas que comparten diversas características clínicas, genéticas, radiológicas y epidemiológicas. La presentación clínica de las espondiloartritis se caracteriza por compromiso del esqueleto axial y articular periférico. El objetivo de este estudio fue evaluar la eficacia de un programa de entrenamiento físico más relajación en el medio acuático en personas con espondiloartritis. Pacientes y método: Estudio clínico aleatorizado de simple ciego en el que 30 personas con espondiloartritis fueron asignadas al azar a un grupo experimental o control. Durante 2 meses al grupo experimental se le aplicó un programa de entrenamiento físico en el medio acuático más relajación (3 sesiones por semana), y al grupo control se le realizaron las evaluaciones los mismos días que al experimental sin que participaran en ningún programa de ejercicio físico supervisado. Los datos obtenidos al inicio del estudio e inmediatamente después de la aplicación de la última sesión fueron: Bath Ankylosing Spondylitis Functional Index («Índice de funcionalidad para las espondiloartritis»), Bath Ankylosing Spondylitis Disease Activity Index («Índice de actividad de la enfermedad del grupo de Bath»), Cuestionario de Salud SF-12 y pulsómetro Sigma PC3® (Sigma-Elektro GmbH, Neustadt, Aemania). Resultados: La prueba U de Mann-Whitney mostró diferencias estadísticamente significativas para la calidad de vida (función física [p = 0,05]), Bath Ankylosing Spondylitis Functional Index (p = 0,015), Bath Ankylosing Spondylitis Disease Activity Index (fatiga [p = 0,032], dolor de cuello, espalda y caderas [p = 0,045], dolor o inflamación en otras articulaciones [p = 0,032] y rigidez matutina la despertar [p = 0,019]). Conclusiones: Los resultados del presente estudio muestran que los tratamientos de ejercicio físico unidos a la relajación aportan beneficios a los pacientes con espondiloartritis y son recomendables como parte del tratamiento de la enfermedad (AU)

Background and objective: Spondyloarthritis is a general term referring to a group of chronic rheumatic illnesses that share clinical, genetic, radiological and epidemiological features. The clinical presentation of spondyloarthritis is characterized by the compromise of both the axial and peripheral articular skeleton. We aimed to evaluate the efficacy of an aquatic exercise plus relaxation program in patients with spondyloarthritis. Patients and method: This was a randomized single blind study including 30 patients with spondylitis who were randomly assigned to an experimental or control group. For 2 months, the experimental group underwent an aquatic fitness plus relaxation program (3 sessions per week). Evaluations were also performed in the control group the same days as the experimental group but they did not participate in any supervised exercise program. The following data were obtained at baseline and immediately after application of the last session: Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Disease Activity Index, Health Questionnaire SF-12 and Sigma PC3® (Sigma-Elektro GmbH, Neustadt, Germany) Heart Rate Monitor. Results: The Mann-Whitney test showed statistically significant differences in the quality of life (physical function [P = .05]), Bath Ankylosing Spondylitis Functional Index (P = .015), Bath Ankylosing Spondylitis Disease Activity Index (fatigue [P = .032], neck pain, back and hips [P = .045], pain or swelling in other joints [P = .032] and in waking morning stiffness [P = .019]). Conclusions: The results of the present study suggest that therapy with physical exercise plus relaxation provides benefits to spondyloarthritis patients and these are advised as a part of their usual treatment (AU)

Spondyloarthrites (SPA) represent a group of heterogenous rheumatic diseases (ankylosing spondylitis/SA, psoriatic arthritis/PsA, reactive arthritis/ReA, spondyloarthritis in bowel inflammatory diseases/BID, undifferentiated spondyloarthritis/undif SpA) with distinct clinical features and common genetic predisposition (HLA-B27). SpA may also affect other organs, ocular involvement, represented by uveitis and conjunctivitis, being one of the most important extraskeletal manifestations. Pathogenic mechanisms of ocular involment in SpA are not entirely known; nevertheless, the inflammatory process which characterizes the main rheumatic diseases seems to be responsible for this extraskeletal manifestation. SpA treatment targeted at clinical remission has a favourable effect not only on articular but also on ocular involvement. The discovery of new pathogenic mechanisms of both rheumatic and eye disease in SpA have contributed to identification of new pathogenic therapies. The interdisciplinary team work of rheumatologists and ophtalmologists have prove essential for the management of SpA patients with ocular manifestations.

Spondyloarthritis in China.

PURPOSE OF REVIEW: Although scientists in China have generated a considerable amount of new information about spondyloarthritis (SpA) in recent years, part of it was published in Chinese. The aim of this review is to summarize all SpA articles for the benefit of English readers. RECENT FINDINGS: In the field of epidemiology, prevalence of SpA in China has been updated, especially with regard to psoriatic arthritis (PsA). In the field of genetics, Chinese scientists have discovered new single-nucleotide polymorphism (SNP) sites association with ankylosing spondylitis (AS) in Han Chinese. In the field of treatment, tumour necrosis factor-alpha (TNF-α) antagonists are wildly used almost as a routine. The usefulness of certain Chinese traditional medicine is undergoing vigorous testing. In the field of diagnosis, ultrasound has been incorporated into the testing tools. In the field of monitoring of disease activity, Ankylosing Spondylitis Disease Activity Scores (ASDAS) has been validated in a cohort of Chinese SpA patients. SUMMARY: Chinese scientists are using cutting-edge technology in the fields of research, diagnosis and management in SpA. What is needed are new approaches that can accommodate the large variations in socioeconomic status of various localities in the vast Chinese continent.
