RESUMO
BACKGROUND: Preference-based measures of health-related quality of life (HRQoL), such as the EQ-5D or the SF-6D, are essential for health economic evaluation. However, they are rarely included in clinical trials of ankylosing spondylitis (AS). This study aims to develop mapping algorithms to predict EQ-5D-3L and EQ-5D-5L health utility scores from the Bath Ankylosing Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI). METHODS: Patients with AS were recruited from the largest tertiary hospital in Shandong province, China, between December 2019 and October 2020. Patients were selected by convenience sampling method according to the following criteria: (1) diagnosed with AS according to the New York criteria; (2) aged 18 years and above; and (3) without mental disorders; (4) able to understand the questionnaires; (5) without serious complications. There were 243 patients who completed the face-to-face questionnaire survey, and 5 cases with missing values in key variables were excluded. Ordinary least squares, censored least absolute deviations, Tobit, adjusted limited dependent variable mixture model and beta-mixture model (BM) in the direct approach and ordered logit and multinomial logit (Mlogit) model in the response approach were used to develop mapping algorithms. Mean absolute error, root mean square error, Spearman's correlation coefficient and concordance correlation coefficient were used to access predictive performance. RESULTS: The 238 patients with AS had a mean age of 35.19 (SD = 9.59) years, and the majority (74.47%) were male. The observed EQ-5D-3L and EQ-5D-5L health utility values were 0.88 (SD = 0.12) and 0.74 (SD = 0.27), respectively. The EQ-5D-5L had higher conceptual overlap with the BASDAI and BASFI than the EQ-5D-3L did. The Mlogit was the best-performing model for the EQ-5D-3L, and the BM showed better performance in predicting EQ-5D-5L than other direct and indirect mapping models did. CONCLUSION: This study demonstrates that the EQ-5D-5L, rather than EQ-5D-3L, should be selected as the target outcome measure of HRQoL in patients with AS in China, and the BM mapping algorithm could be used to predict EQ-5D-5L values from BASDAI and BASFI for health economic evaluation.

Axial spondyloarthritis (axSpA) is an inflammatory joint disease, in which the dominant symptom is inflammatory back pain. It affects approximately 1% of the population, with a higher incidence in males. Spinal pain associated with spondyloarthritis is referred to as inflammatory back pain. In clinical practice, it is extremely important to be able to assess the activity of inflammatory back diseases and to select appropriate treatment and monitor the therapy. Currently, two main tools are used for assessment of the activity of axial spondyloarthritis: BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) and ASDAS (Ankylosing Spondylitis Disease Activity Score). The BASDAI is a tool used for years for assessment of disease activity, determining eligibility for treatment, and making decisions about continuation of therapy. Since BASDAI depends entirely on patient self-assessment, it is considered less objective than the ASDAS index. In turn, the latter includes not only answers to questions provided by the patient but also a parameter of inflammation such as erythrocyte sedimentation rate or C-reactive protein (CRP). Additionally, increasing numbers of studies report advantages of the ASDAS index over BASDAI. Moreover, as indicated by ASAS/EULAR (Assessment in Spondyloarthritis International Society/European Alliance of Associations for Rheumatology) 2022, ASDAS, especially ASDAS-CRP is the preferred tool for assessment of the activity of axSpA, whereas BASDAI is used only when the evaluation of the ASDAS is not possible. This paper presents the definition and symptoms of axSpA and reviews the latest research on ASDAS and BASDAI, with emphasis on the objectivity of the ASDAS assessment also presenting the doubts and limitations concerning this tool.
RESUMO
OBJECTIVES: The alternative ASDAS (altASDAS) is an index that can be used when patient global assessment is unavailable. Our aim was to test the truth and discrimination aspects according to OMERACT filter 2.0 of the altASDAS in an external cohort. METHODS: Cohorts from the COAST trials of ixekizumab (COAST-V, -W, -X; 16-week primary endpoint) enrolling radiographic/non-radiographic axial SpA patients were pooled. The ASDAS [original formula with patient global assessment (PGA)] and altASDAS were calculated. Truth was assessed by agreement with the continuous ASDAS [intraclass correlation coefficients (ICCs)] and ASDAS disease activity (DA) states (weighted κ), Bland-Altman plots [mean difference (MD) and 95% limits of agreement (LoA)] and Pearson's correlations between altASDAS/ASDAS and other constructs. Discrimination was tested by the ability of altASDAS to distinguish high/low DA according to nocturnal pain >6/10 as an external anchor and agreement (κ) with ASDAS in major improvement (MI) and clinically important improvement (CII). RESULTS: A total of 958 patients were included. For truth, agreement with ASDAS was very good (ICC = 0.99, κ = 0.91), MD with ASDAS was 0.03 (95% LoA -0.31-0.24) and correlation coefficients of altASDAS with related constructs were within a prespecified 0.3-wide band around those between ASDAS and the same construct. For discrimination, the altASDAS discriminated between DA states and agreed with ASDAS response (κ MI = 0.91, CII = 0.93). CONCLUSIONS: The altASDAS was truthful and discriminative in an external cohort and as such has been fully validated to be used in cases when PGA is unavailable.

OBJECTIVE: To determine cut-off values of BASDAI that can discriminate the four disease activity states (inactive disease, moderate disease activity, high disease activity and very high disease activity), separated by the validated Ankylosing Spondylitis Disease Activity Score (ASDAS) cut-off values (1.3, 2.1 and 3.5). METHODS: We included 333 patients with axial SpA whose data on BASDAI and ASDAS-CRP were available. Receiver operating characteristic curve analysis was performed to determine the BASDAI cut-off values that best corresponded to ASDAS-CRP cut-off values. The degree of agreement between disease activity states based on the BASDAI and ASDAS-CRP cut-off values was assessed using weighted kappa. RESULTS: Of the total 333 patients, 52 (15.6%), 190 (57.1%), 76 (22.8%) and 15 (4.5%) patients had inactive disease, moderate disease activity, high disease activity and very high disease activity, respectively, according to the ASDAS-CRP. Receiver operating characteristic analyses revealed that the BASDAI values 1.9 [area under the curve (AUC) 0.948; 95% CI 0.922, 0.974], 3.5 (AUC 0.926; 95% CI 0.887, 0.966) and 4.9 (AUC 0.917; 95% CI 0.837, 0.996) best corresponded to the ASDAS-CRP values 1.3, 2.1 and 3.5, respectively. The degree of agreement between disease activity states based on the BASDAI and ASDAS-CRP cut-off values was good (weighted kappa: 0.724, P <0.001). CONCLUSION: The BASDAI values 1.9, 3.5 and 4.9 corresponded to the ASDAS-CRP values 1.3, 2.1 and 3.5, respectively. These cut-off values could be useful in clinical studies and real-world practice for determining disease activity status when ASDAS-CRP is unavailable.

AIM: To assess the dynamics of activity of ankylosing spondylitis (AS) during the year after childbirth, to identify predictors of high activity. MATERIALS AND METHODS: 75 pregnant with confirmed AS (modified New York criteria, 1984) were included for prospective observation. Of these, 44 women were followed up for 1 year after delivery. The average age of the patients was 32.55.8 years, the duration of the disease was 149.096.3 months. Lactation was established in 40 women and the duration was 10 [4; 12] months. RESULTS: The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) at 1, 6 and 12 months after giving birth was 2.4 [1.4; 4.2], 2.6 [1.4; 4.4] and 2.7 [1.5; 4.1], respectively (p0.05). ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score C-reactive protein) was 2.0 [1.2; 2.7], 1.9 [1.4; 2.5] and 1.7 [1.3; 2.3], respectively (p0.05). There were no differences between the values of BASDAI, ASDAS-CRP between women with and without lactation. Predictors of high AS activity (BASDAI4) 1 month after delivery were: BASDAI4 in the 1st (odds ratio OR 8.1; 95% confidence interval CI 1,837,0) and 2nd trimesters of pregnancy (OR 5.1, 95% CI 1.220.6); NRS back pain 4 in the 2nd trimester (OR 4.3, 95% CI 1.117.2); cancellation of biological disease-modifying antirheumatic drugs therapy in the 1st trimester of pregnancy (OR 21.0, 95% CI 1.0440.9). Predictors of high AS activity in 6 months after delivery were: BASDAI4 in the 1st (OR 6.5, 95% CI 1.528.7), in the 2nd (OR 6.7, 95% CI 1.627.8) and in the 3rd trimesters of pregnancy (OR 8.7, 95% CI 1.938.6); high activity in 1 month after delivery (OR 4.0, 95% CI 1.015.9). CONCLUSION: AS activity remains stable for 1 year after delivery. High AS activity during pregnancy was a risk factor for high activity within 6 months after delivery.

BACKGROUND: The purpose of this study was to determine the prevalence of high disease activity as measured using the Ankylosing Spondylitis Disease Activity Score (ASDAS) in ankylosing spondylitis (AS) patients who nonetheless have low Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores after anti-tumor necrosis factor (TNF) treatment. Its clinical impact on anti-TNF survival was also investigated. METHODS: We conducted a single-centre retrospective cohort study of AS patients having low BASDAI scores (< 4) and available ASDAS-C-reactive protein (CRP) data after 3 months of first-line anti-TNF treatment. Patients were grouped into high-ASDAS (≥ 2.1) and low-ASDAS (< 2.1) groups according to the ASDAS-CRP after 3 months of anti-TNF treatment. Their characteristics were compared. And survival analyses were carried out using Kaplan-Meier curves and log-rank test with the event being discontinuation of anti-TNF treatment due to lack/loss of efficacy. RESULTS: Among 116 AS patients with low BASDAI scores after 3 months of anti-TNF treatment, 38.8% were grouped into the high-ASDAS group. The high-ASDAS group tended to have greater disease activity after 9 months of treatment (BASDAI 2.9 ± 1.1 vs. 2.3 ± 1.4, p=0.007; ASDAS-CRP 1.8 ± 0.6 vs. 1.5 ± 0.7, p=0.079; proportion of high ASDAS-CRP 27.8% vs. 13.8%, p=0.094) and greater risk of discontinuing anti-TNF treatment due to lack/loss of efficacy than the low-ASDAS group (p=0.011). CONCLUSIONS: A relatively high proportion of AS patients with low BASDAI scores had high ASDAS-CRP. These low-BASDAI/high-ASDAS-CRP patients also had a greater risk for discontinuation of anti-TNF treatment due to low/lack of efficacy than the low-ASDAS group. The use of the ASDAS-CRP alone or in addition to the BASDAI may improve the assessment of AS patients treated with anti-TNF agents.

PURPOSE: The aim of this study is to evaluate the possible effects of (ankylosing spondylitis) AS on choroidal thickness (CT) and other retinal layers using spectral domain optical coherence tomography (SD-OCT). METHODS: This cross-sectional study group comprised 41 AS patients and age and sex-matched 46 control subjects. None of our patients had active anterior uveitis during the measurements. We evaluated and compared CT, retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, focal loss volume (FLV) and global loss volume (GLV) of the participants. RESULTS: The CT of the patients at 1500 µm (286.20 µm ± 65.81), 1000 µm (309.55 µm ± 85.33) nasally to the fovea and subfoveal layer (339.93 µm ± 69.93) were thicker than in controls (p = 0.007, p = 0.037, p = 0.008). Except nasal layer, all RNFL layers were significantly thinner than controls (p < 0.001). GCC and macular thickness were also thinner than controls (p < 0.001). CONCLUSION: In conclusion, present findings may suggest that the AS disease may affect the choroidal, RNFL and GCC thickness by disease's own inflammatory effect, independently from the uveitis history.

OBJECTIVE: The aim: To assess the level of hepcidin in patients with AS, to determine its connection to the disease and various forms of anemia. PATIENTS AND METHODS: Materials and methods: 118 patients with ankylosing spondylitis were examined and hematological, biochemical, immunologic indicators of the general parameters of hematopoiesis and ferrokinetics, plasma levels of CRP, IL-6 and hepcidin were determined. RESULTS: Results: It was found that high levels of hepcidin are found in 25% of patients with AS, 50% are limiting and only 25% are optimal. The serum levels of hepcidin in patients with AS are independent of the age, sex, and duration of the disease, but are closely associated with the activity (ESR, CRP, IL-6, BASDAI, and ASDAS levels) of the disease. Close pathogenetic connection of hepcidin with the formation of anemic syndrome was established. Patients with ACD were characterized by the highest levels of hepcidin. CONCLUSION: Conclusions: Hepcidin plays an important role in the pathogenesis of ACD in patients with AS and can be used as a diagnostic marker for differential diagnosis.

OBJECTIVE: The aim: To estimate the prevalence of anemia in patients with ankylosing spondylitis, major pathogenetic variants and their relationship with the activity of the inflammatoryprocess and the severity of the disease. PATIENTS AND METHODS: Materials and methods: 118 patients with ankylosing spondylitis participated in the study, which performed hematologic, biochemical, immunological studies with general haemopoiesis and ferrokinetics parameters, plasma levels of CRP and IL-6. RESULTS: Results: It was found that in Ukrainian population of patients with ankylosing spondylitis, 28.8% of patients has anemic syndrome. The anemia spectrum is represented by ACD (44.1%), ACD with iron deficiency (29.4%) and IDA (23.5%). It is shown that the severity of anemic syndrome increases with the increase of the stage of activity of the inflammatory process. The presence and severity of anemia are closely related to the severe course of the disease, evaluated by the BASDAI and ASDAS index, and laboratory markers of inflammation CRP and IL-6 of serum. CONCLUSION: Conclusions: The obtained data is promising for the search of effective means of correction of anemic syndrome in patients with ankylosing spondylitis.

OBJECTIVES: The aim of the study is to evaluate the performance of extreme patient-reported outcomes (PRO) against definitions of fibromyalgia (FM) in patients with axial spondyloarthritis (axSpA). METHODS: Ancillary analysis of the Predict-SpA trial, an observational study of axSpA patients receiving TNF-α inhibitor, was performed. 'Extreme PRO' was defined as a score ≥ 8 on three out of the first five Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) questions (scored 0-10). FM was defined by the American College of Rheumatology (ACR) 1990 criteria and the Fibromyalgia Rapid Screening Test (FiRST). Performances of 'extreme PRO' for FM were evaluated by the sensitivity, specificity and positive likelihood ratio using the 1990 ACR criteria as gold standard. As secondary analysis, the FiRST was used as the external standard. RESULTS: The prevalence of 'extreme PRO' in this population was 28.8% at baseline and decreased to 9.9% at 12 weeks. 'Extreme PRO' had low sensitivity 12 weeks after TNF initiation (0.18, 95% confidence interval [CI] 0.10-0.27 vs 0.60, 95% CI 0.50-0.71, at baseline), but high specificity (0.92, 95% CI 0.89-0.94 vs 0.78, 95% 0.74-0.82, at baseline), using ACR 1990 criteria as gold standard. Performances when tested against FiRST at 12 weeks showed higher sensitivity (0.27, 95% CI 0.20-0.35) and specificity (0.96, 95% CI 0.94-0.98). CONCLUSION: The proposed extreme PRO definition showed great specificity for FM recognition in patients with axSpA, suggesting it could be used in observational studies when specific items for FM classification are not available.

This review explores the prevalence and factors associated with disturbed sleep for patients with ankylosing spondylitis and non-radiographic axial spondyloarthritis in order to clarify consistent findings in this otherwise disparate research field. The association of physical, demographic and psychological factors correlating with poor sleep was explored, and the effectiveness of interventions assessed. Ten electronic databases were searched: AMED, CINAHL, Embase, Medline, PsycINFO, PubMed, Scopus, Web of Science, OpenGrey and BASE. Following application of inclusion and exclusion criteria, 29 articles were critically assessed on the basis of methodology, experimental design, ethics and quality of sleep data, leading to the selection of 15 studies for final review. Poor sleep was reported in 35-90% of patients with axial spondyloarthritis and is more prevalent within this clinical population compared to healthy control subjects. Disturbed sleep is an important aspect of disease for patients and reflects the severity of disease activity, pain, fatigue and functional disability. However, the direction of this relationship is undetermined. Associations with age, gender, years spent in education, quality of life and depression have also been demonstrated. Anti-TNF medication is effective in reducing poor sleep, and exercise has also produced beneficial results. Future research into poor sleep should take account of its multifactorial nature. There is also a current lack of research investigating non-pharmacological interventions or combination therapies. A standardised, validated measurement of poor sleep, appropriate for regular patient screening, would be a useful first step for future research.

The objective of the study was to study the clinical utility of the Ankylosing Spondylitis Disease Activity Score (ASDAS) for the assessment of disease activity in ankylosing spondylitis (AS) patients, compared to the Bath Ankylosing Spondylitis Activity Index (BASDAI). This was a prospective longitudinal observational study in patients with AS (NY-modified criteria) from 23 Spanish centers. Physical and analytical data; global, lumbar, and nocturnal pain; ASDAS, BASDAI and minimally acceptable clinical status (PASS) were collected. Psychometric characteristics of both indexes were analyzed: construct validity (convergent and divergent), discriminant capacity, criterion validity (global physician and patient assessment), and sensitivity to change. The study involved 127 patients (19.7% attrition). Both BASDAI and ASDAS showed a higher correlation with patient's global assessment (r = 0.76 and 0.70, respectively) than with physician's global assessment (r = 0.67 and 0.57). Both scores allowed discriminating patients with an acceptable clinical status, although BASDAI to a greater extent than ASDAS (Cohen δ 1.72 vs 0.88 for the medical PASS). Both scores showed sensitivity to change in patients who changed from an unacceptable symptomatic state to acceptable according to PASS criteria (physician and patient) and by BASDAI 50 response criteria (Cohen δ > 0.80). BASDAI showed better criterion validity than ASDAS, both for the patient PASS (AUC 0.85 vs 0.79) and for the physician's (AUC 0.90 vs 0.79). ASDAS shows adequate performance for disease activity in patients with AS; however, in this study, its psychometric properties do not present advantages over BASDAI in terms of criterion validity, sensitivity to change or discriminative capacity; replacement of BASDAI by ASDAS is not supported by the data.

The objective of this retrospective study was to evaluate the prevalence of comorbid Posttraumatic stress disorder (PTSD) and the association of PTSD with pain, disease activity, and medication use in ankylosing spondylitis (AS). Veterans with one or more visit to an outpatient rheumatology clinic at a single Veterans Affairs site during a 2-year study period were identified by ICD codes for AS and included if there was documentation of AS diagnosis by a rheumatologist. Data were collected on PTSD diagnosis, demographics, pain scores, disease activity by the Bath AS Disease Activity Index (BASDAI), and medication use. Characteristics were compared by PTSD status using t tests for continuous variables and Chi-square or Fischer's exact test for categorical variables. Of 113 Veterans with AS, 20 (18%) had a diagnosis of PTSD. Those with PTSD were significantly younger, 52 ± 17 years, as compared to those without PTSD, 59 ± 14 years (p = 0.04). BASDAI was recorded for 30% with a mean score of 4.3 ± 2.0. Those with PTSD had higher mean pain and BASDAI scores as compared to those without PTSD (p = 0.06 for both comparisons). Prescribed medications were similar for both groups in regards to synthetic disease modifying antirheumatic drugs (DMARDs), biologics, and opioids, although those with PTSD were significantly more likely to receive NSAIDs (p = 0.03). Veterans with AS and comorbid PTSD were younger and had higher reported pain and disease activity scores compared to those without PTSD in this single site study. These findings underscore the importance of identifying PTSD in patients with AS.

Physical activity is recommended in axial spondyloarthritis (axSpA) but may be insufficiently performed. The objective of this study was to assess physical activity in axial spondyloarthritis and to explore its explanatory factors. This was a cross-sectional study of patients with definite axSpA. The level of physical activity (International Physical Activity Questionnaire-Long form, IPAQ-L), type of aerobic exercise and the Exercise Benefits and Barriers Score were collected. Multivariate logistic regression analyses were performed to explain levels of exercise at least as recommended by the World Health Organization. In all, 203 patients were included: mean age 46.0 ± 11.6 years, 108 (53.2 %) males, mean Bath Ankylosing Spondylitis Activity Index (0-100) 37.8 ± 19.9; 137 (68.8 %) were treated with TNF-inhibitors. In all, 111 patients (54.7 %) were exercising at least as recommended; 96 (47.2 %) were in the 'high physical activity' category. Aerobic exercise >30 min was performed at least once a week by 61 (30.0 %) patients; the most frequent activities were energetic walking (31.0 %) and swimming (21.2 %). Main perceived benefits of exercising were improving physical fitness and functioning of the cardiovascular system, and the main barrier was physical exertion. Patients with paid employment had lower levels of physical activity whereas other demographic variables, disease activity/severity or TNF-inhibitor treatment were not predictive. One half of these patients performed enough physical activity according to the recommendations, similarly to the French population. Levels of physical activity did not appear to be explained by disease-related variables. Physical activity should be encouraged in axSpA.

Ankylosing spondylitis (AS) is a chronic inflammatory disorder that mainly affects the sacroiliac joints and axial skeleton. The aim of this study was to assess serum prolidase level (SPL) and its association with disease activity in patients with AS. This prospective study included 75 AS patients. Thirty age- and gender-matched healthy controls were enrolled. AS patients were considered as active if BASDAI score was ≥4 or inactive if BASDAI score was <4. There were 34 AS patients in the active group and 41 AS patients in the inactive group. Anti-TNF-monoclonal antibody treatment was started in patients in the active group. These active patients were reassessed 6 months later. BASDAI, ASDAS, visual analogue scale, short-form-general health survey questionnaire, C-reactive protein, erythrocyte sedimentation rate and SPL were measured in all AS patients before and after treatment. The SPL was significantly lower in inactive AS patients than in control group, and also, SPL was significantly lower in active AS patients than in inactive patients. All activity parameters were successful in separating active and inactive AS patients. However, the only parameter that could distinguish active patients from inactive patients was prolidase. The optimum cutoff point of SPL to identify patients with active AS was 23.13 ng/mL with sensitivity, specificity, positive predictive value and negative predictive value of 100 %. Serum prolidase level was successful in measuring disease activity and had as high sensitivity and specificity as BASDAI and was superior to other activity parameters.

OBJECTIVES: Type D personality was identified as an important factor that can explain the differences in clinical outcomes in various diseases. The aim of this study is to clarify the relationships between Type D personality and clinical status of patients with Ankylosing Spondylitis (AS). METHODS: The scores of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS)-C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), the Bath Ankylosing Spondylitis Functional Index (BASFI), the 36-Item Short-Form Health Survey (SF-36), and 14-item Type D Scale (DS-14) were noted. RESULTS: We found significantly higher levels of the BASDAI, the BASFI, and the SF-36 mental subscale scores in patients with Type D personalities compared to those who were Non-Type D (p < 0.05). The total DS-14 scores were found to be correlated with the scores of physical and mental subscales of SF-36, the BASDAI, the BASFI, ASDAS-CRP, and ESR (p < 0.05). In logistic regression analysis, the occurrence of Type D personality was found to be an independent predictor for disease activity of AS due to BASDAI and ASDAS-ESR (p = 0.016, OR, 95% CI = 2.98,1.23-7.22; p = 0.022, OR, 95% CI = 2.78,1.16-6.63 respectively). CONCLUSIONS: Patients may over-rate self-reported measurements such as the BASDAI, BASFI, and SF-36 related to their interpersonal characteristics. Therefore, including the Type D personality, which is a stable construct in evaluating AS patients with brief and valid DS-14, may be noteworthy.

To investigate the association between smoking and clinical, inflammatory and radiographic parameters in patients with ankylosing spondylitis (AS). One hundred and six tumour necrosis factor inhibitor naïve patients with AS were included in the study. The erythrocyte sedimentation rate, C-reactive protein, Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI) and modified Stroke AS Spine Score (mSASSS) were assessed cross-sectionally for each patient. Smoking history was obtained, and smoking pack years were calculated. Current smokers had significantly higher BASDAI (p < 0.001) and a trend for higher BASFI (p = 0.059). Ever smokers had significantly higher BASFI (p = 0.035) and a trend for higher mSASSS (p = 0.063) compared to never smokers. Pack years (smoking intensity) were positively correlated with duration of inflammatory back pain (r = 0.628, p < 0.001), BASFI (r = 0.443, p < 0.001) and mSASSS (r = 0.683, p < 0.001). Multivariate regression analyses showed that current smoking was independently associated with a higher BASDAI score [regression coefficient (B) = 14.75, p < 0.001] and increasing pack years were independently associated with higher mSASSS (B = 0.26, p = 0.005). In patients with AS, current smoking was strongly and independently associated with higher disease activity, and cumulative smoking exposure with more radiographic spinal damage. In AS smokers, smoking cessation should be strongly recommended.

OBJECTIVE: Ankylosing spondylitis (AS) is a progressive chronic inflammatory disease mainly characterized by axial skeleton and sacroiliac joint involvement. We aimed to investigate the relation between neutrophil-to-lymphocyte ratio (NLR) and disease severity of AS and to explore its availability in clinical practice. METHODS: A total of 102 AS patients and 60 individuals who were age- and gender-compatible with the control group were included into the study. Patients were divided into 2 groups according to Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores. Patients with BASDAI scores < 4 were considered to be having mild disease activity, whereas those with scores ≥ 4 were considered to be displaying severe disease activity. Hemogram test during the diagnosis, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and other laboratory values of the control group were recorded. RESULTS: NLR was observed to be higher in AS patients compared to the controls (2.47 ± 1.33 and 1.72 ± 0.47; respectively; p<0.0001). NLR was observed to be significantly higher in severe AS disease activity compared to the mild AS disease activity (2.72 ± 1.41, 2.20 ± 1.19; respectively; p = 0.001). NLR had statistical significant differences between mild disease activity compared to the controls (2.20 ± 1.19 and 1.72 ± 0.47, respectively; p = 0.263). There was a positive correlation between NLR and BASDAI (r = 0.193, p = 0.041). The performance of NLR evaluating the disease severity by Roc analysis had sensitivity of 69%, specificity of 54% (cut-off value 1.91), and AUC of 0.652 (95% Cl, 0.549-0.755) (p = 0.006). CONCLUSIONS: NLR may be a simple and inexpensive marker to indicate disease activity in patients with AS in daily clinical practice (Tab. 3, Fig. 3, Ref. 25).
RESUMO
Objectives: The study aimed to evaluate the correlation between the clinical disease activity of axial spondyloarthropathy (axSpA) and magnetic resonance imaging findings of the sacroiliac joint. Patients and methods: Thirty-two patients (21 males, 11 females; mean age: 39.3±9.2 years; range, 18 to 55 years) who were diagnosed with axSpA according to the Assessment in Spondyloarthritis International Society classification criteria between November 2015 and August 2017 were included in this cross-sectional study. Visual Analog Scale (VAS), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS)-erythrocyte sedimentation rate (ESR), and ASDAS-C-reactive protein (CRP) were used as the indicators of clinical activity. Magnetic resonance imaging of the sacroiliac joint was performed and the Spondyloarthritis Research Consortium of Canada (SPARCC) score was evaluated by a radiologist who was blinded to the clinical and laboratory parameters of the patients. Results: The mean duration of symptom onset was 9.3±7.7 years, and the mean duration of diagnosis was 3.6±2.8 years. Human leukocyte antigen (HLA)-B27 was positive in 16 (50%) patients. There was no correlation between the SPARCC score and VAS, BASDAI, MASES, BASFI, ASDAS-CRP, ASDAS-ESR, ESR, and CRP values (p>0.05). In the HLA-B27 subgroup analyses, a statistically significant correlation was found between HLA-B27-negative patients and SPARCC score (r=0.639, p=0.008). Conclusion: No relationship was found between other clinical disease parameters and sacroiliac joint imaging findings, except for the relationship between the SPARCC and BASDAI in HLA-B27- negative patients with axSpA.
RESUMO
OBJECTIVE: To determine the impact of the disease in patients with PsA in daily clinical practice and to evaluate its relationship with its axial activity. METHODS: A cross-sectional study was conducted in consecutive patients attended from January 2021 to December 2021 who met the CASPAR criteria, with clinical of inflammatory back pain and positive axial imaging, with or without peripheral involvement. Demographic, clinical, analytical data, HAQ index, PsAID12 and activity index (BASDAI and ASDAS-PCR) were also collected. Patients were divided into two groups, those with high impact and those with low impact according to PsAID results. Continuous variables are shown as median (Q1-Q3) and categorical variables as percentages and frequencies. RESULTS: Of the 269 patients evaluated with PsA, 72 patients with axial involvement were included, 40 men (55.6%), with a median age of 54.1 years and disease duration of 7 years. 28.3% of the patients were obese and serum CRP level was 0.45â¯mg/dl (0.08-1.10). BASDAI was 4.2 (2.0-6.2) and ASDAS-PCR was 2.4 (1.5-3.2), which translates into 39.6% of patients in low activity or remission. The median PsAID total score was 3.9 (1.6-5.4), evaluated in 61 patients. The patients who achieved a PsAID12â¯≤â¯4 were 63%, mostly men and with lower CRP levels than PsAIDâ¯≥â¯4 patients. In addition, low impact measured by the PsAID12 was associated with low results in BASDAI and ASDAS-PCR. CONCLUSIONS: Axial involvement reflected lower impact of the disease measured by PsAID12 and it is correlated with low activity measured by BASDAI and ASDAS-PCR.
