Psychological correlates of self-reported functional limitation in patients with ankylosing spondylitis
Abstract Introduction Functional status is an integral component of health-related quality of life in patients with ankylosing spondylitis (AS). The purpose of this study was to investigate the role of psychological variables in self-reported functional limitation in patients with AS, while controlling for demographic and medical variables. Methods 294 AS patients meeting modified New York Criteria completed psychological measures evaluating depression, resilience, active and passive coping, internality and helplessness at the baseline visit. Demographic, clinical, and radiologic data were also collected. Univariate and multivariate analyses were completed to determine the strength of correlation of psychological variables with functional limitation, as measured by the Bath AS Functional Index (BASFI). Results In the multivariate regression analysis, the psychological variables contributed significantly to the variance in BASFI scores, adding an additional 24% to the overall R-square beyond that accounted by demographic and medical variables (R-square 32%), resulting in a final R-square of 56%. Specifically, arthritis helplessness, depression and passive coping beside age, ESR and the Bath AS Radiograph Index accounted for a significant portion of the variance in BASFI scores in the final model. Conclusions Arthritis helplessness, depression, and passive coping accounted for significant variability in self-reported functional limitation beyond demographic and clinical variables in patients with AS. Psychological health should be examined and accounted for when assessing functional status in the AS patients

Spine fractures in ankylosing spondylitis: A case report and review of imaging as well as predisposing factors to falls and fractures
BackgroundAnkylosing spondylitis (AS), an inflammatory arthritis that affects the axial skeleton, predisposes patients with severe disease to falls and spinal fractures. Advanced imaging has improved the process of fracture detection. In spite of increased knowledge about early diagnosis and management of AS, little attention is being paid to the environmental hazards that pose a risk for patient outcome.ObjectivesTo identify risk factors for falls and fractures and evaluate imaging modalities in the detection of fractures in AS patients.MethodsA case report and review of the literature using PubMed for English articles from 2000 to 2013 regarding AS patients׳ risk factors for falls and fractures and imaging modalities used to diagnose fracture in this population.ResultsPotential impairments in balance and coordination in the AS population include vestibular dysfunction, thoracolumbar kyphosis, and deficits in proprioception. A common and significant environmental risk factor for falls includes the use of a tub-shower arrangement. Furthermore, osteoporosis is a well-known complication of AS, which can predispose to a fracture. Lastly, there are no comprehensive studies that have evaluated the ability of advanced imaging modalities to identify an acute spine fracture in this patient population.ConclusionsAS patients with advanced disease are at an increased risk of falls and fractures due to many factors including but not limited to a rigid spine and difficulty with peripheral vision. A tub-shower arrangement commonly found in homes and hotel rooms is a major hazard. A consistent approach to diagnosis of fractures involving advanced imaging recommendations should be considered

Regional radiographic damage and functional limitations in patients with ankylosing spondylitis: Differences in early and late disease
ObjectiveBoth radiographic damage and functional limitations increase with the duration of ankylosing spondylitis (AS). We examined whether radiographic damage contributed more to functional limitations in late AS than in early AS, and if the strength of association varied with the anatomic region of damage.MethodsIn this cross-sectional study of 801 patients with AS, we examined associations of the lumbar modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), the cervical mSASSS, lumbar posterior fusion, cervical posterior fusion, and hip arthritis with the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Health Assessment Questionnaire modified for the spondyloarthritides (HAQ-S).ResultsHigher lumbar and cervical mSASSS scores were associated with more functional limitations, but there was an interaction between mSASSS scores and the duration of AS, such that the strength of their association with functional limitations decreased with increasing duration of AS. Cervical posterior fusion was associated with worse functioning independent of mSASSS scores. Hip arthritis was significantly associated with functional limitations independent of spinal damage measures. Among patients with AS duration ≥40 years, the number of comorbid conditions accounted for most of the variation in functioning. Results were similar for both the BASFI and the HAQ-S.ConclusionAlthough both radiographic damage and functional limitations increase over time in AS, the relative contribution of radiographic damage to functional limitations is lower among patients with longstanding AS than with early AS, suggesting patients may accommodate to limited flexibility. Damage in different skeletal regions impacts functioning over the duration of AS. Functional limitations due to comorbidity supervene in late AS
