ABSTRACT The national registry of spondyloarthropathies (REGISPONSER) is launched to classify patients with this group of diseases treated in Spanish rheumatology clinics. This manuscript describes the methodological and organizational background as well as characteristics of patients finally included, and provides a comparative analysis between characteristics of both ankylosing spondylitis and undifferentiated spondyloarthropathy groups of patients.
Twelve members of the GRESSER group have participated in the registry, for a one-year recruitment period. All consecutively registered adult patients treated in their clinics met the classification criteria of the European Spondyloarthropathies Study Group (ESSG). Data collected reflect the socio-demographic characteristics, as well as disease activity and functional status, clinical form at onset, treatment used and quality of life; all measured by standard instruments.
Throughout 1 yr, 1385 patients have been included in the registry: 939 males (68%) and 440 females (32%), with an average age of 47 +/- 13 years (mean +/- s.d.), and an average disease duration of 12 +/- 9 years. Diagnoses of the included patients were: AS (n = 842, 61%), PsA (n = 290, 21%), u-SpA (n = 205, 15%), reactive arthritis (n = 16, 1.2%), inflammatory bowel disease arthritis (n = 13, 0.9%) and JCA-spondyloathropathy (n = 13, 0.9%). Regarding clinical form, 54% had axial disease, 20% peripheral disease, 24% mixed disease and 0.6% isolated enthesitic form. Low-back pain was the first symptom reported in 53% of the patients, and most common extra-articular disease manifestations were psoriasis (25%), anterior uveitis (16%) and intestinal inflammatory disease (4%). Some kind of work disability was reported by 353 patients (25.5%).
Such databases are very useful to obtain information about characteristics of SpA patients treated in a certain location or following a specific treatment practice, and provide a tool for assessing the impact of the disease. Data collected in this registry provide an appropriate clinical and demographic profile of patients suffering from SpA in Spain.

    ABSTRACT: The objective of this study is to identify single-nucleotide polymorphisms (SNPs) predictors of treatment nonresponse to the first anti-TNF-alpha agent in ankylosing spondylitis (AS). Patients were classified as "nonresponders" if they failed to achieve improvement ≥50 % of the initial BASDAI. We selected candidate SNPs previously reported, associated with susceptibility or pathogenesis of AS and with other spondylarthropaties (SpAs). The predictors of nonresponse were modeled with multiple logistic regression. The predictive power of the genetic model of nonresponse to treatment was tested with AUC-ROC. One hundred and twenty-one (121) AS patients fulfilled the inclusion criteria. Of the candidate SNPs tested for association with treatment effectiveness, five independent predictors were identified: rs917997, rs755622, rs1800896, rs3740691, and rs1061622. The genetic model of nonresponse to treatment had a predictive power of 0.77 (95 % CI 0.68-0.86). Our study identified several polymorphisms which could be the useful genetic biomarkers in predicting nonresponse to anti-TNF-alpha therapy.

    ABSTRACT: Ankylosing spondylitis quality of life (ASQoL) is an instrument for assessing quality of life (QoL). The aims of this study were to assess the reliability of Persian version of ASQoL questionnaire and evaluation of QoL status and related factors in ankylosing spondylitis (AS). One hundred and sixty-three Iranian patients with AS who fulfilled modified New York criteria were enrolled. Patients were evaluated using questionnaires including demographic and clinical variables, Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), fatigue, Bath AS Metrology Index, pain and ASQoL. Reliability and validity of Persian version of ASQoL were evaluated by test-re-test agreement, internal consistency and correlation with specific scales. Relationship of parameters with ASQoL was analyzed by multiple regression. Age, disease duration and ASQoL score (mean ± SD) were 37.74 ± 9.88, 14.49 ± 8.47 and 8.02 ± 5.28 years, respectively. Test-re-test reproducibility for ASQoL was good as assessed by intra-class correlation coefficient (ICC: 0.97, P < 0.001). Internal consistency was high (Cronbach's alpha: 0.91). Convergent validity was confirmed by correlation of ASQoL score with specific scales (BASFI, r = 0.74, BASDAI, r = 0.6, fatigue, r = 0.56, depression, r = 0.24, intermalleolar distance, r = -0.44 and educational level, r = -0.37). Persian version of ASQoL is a valid and reliable scale to assess QoL in AS. Function, fatigue, mood, hip mobility and education are the factors which should be noted to achieve the best QoL.

    ABSTRACT: A cross-sectional study was performed to assess the correlation between telephone and self-administration of patient-related outcomes (PROs) used in the assessment of ankylosing spondylitis (AS) patients. Participants underwent a telephone interview in which the following measures were evaluated: numerical rating scales (NRSs) for global health, pain intensity, global pain, back pain, and back pain at night; BASDI, BASFI, Health Assessment Questionnaire (HAQ), ASQoL, EuroQol, SF-12, and Work Productivity and Activity Impairment (WPAI) questionnaire. Within 48 h after the telephone interview, patients were appointed for a clinical visit in which the same questionnaires and in the same order were self-administered. The degree of correlation of outcomes measures between telephone interview and self-administration was assessed with the intraclass correlation coefficient (ICC). The two modes of assessing PROs were highly reliable, with ICC of 0.81 for BASDAI, 0.82 for BASFI, and 0.75 for HAQ. NRSs for global health, global pain intensity, back pain, and back pain at night also showed ICCs between 0.51 and 0.70, and only NRS for global disease activity showed an ICC of 0.45. This results were similar in patients with AS and patients with psoriatic arthritis. Social functioning and mental health domains of the SF-12 as well as EuroQol had poor correlations. The ICCs for WPAI outcomes were very good or good. We conclude that PROs in AS patients are comparable in both self-administered paper questionnaires and via a telephone interview. Different modes of assessing PRO measures facilitate the assessment of patients with AS in routine practice.
