Studies with an enthesis index as a method of clinical assessment in ankylosing spondylitis.

چکیده
The histopathological characteristic of ankylosing spondylitis (AS) is the presence of chronic enthesitis. Our aim was to develop a clinical measurement of the severity of tenderness over entheses. The scoring system was based on the patients' response to palpation over entheses easily accessible to examination. The enthesis index (EI) correlated with pain (r = 0.67, p less than 0.01) and stiffness (r = 0.46, p less than 0.05) scores. A single, blind, crossover study was conducted to determine the sensitivity of the index to change in clinical state associated with non-steroidal antirheumatic drug therapy and to record the interobserver variability. The index showed significantly lower scores after one week's drug treatment (p less than 0.05). The EI is a convenient, non-invasive measure of disease severity in patients with AS. Potential applications include the assessment of enthesitis in other polyarthritides and a means of distinguishing clinically between severity of enthesitis and synovitis in different types of polyarthritis.

Background: Increased incidence of renal stone has been reported in ankylosing spondylitis (AS), but unlike some well-known renal involvements, they have not been fully studied. The aim of this study was to investigate the association of AS with urolithiasis and also the relation between urinary stone and severity markers. Methods: One hundred-sixty three AS patients were included in a cross-s...

A large number of variables are available for the assessment of disease activity in ankylosing spondylitis (AS). The aim of this study was to evaluate the validity of commonly used variables, to select a core set of valid variables for disease activity and finally to compute an AS disease activity score (AS-DAS). Data from two longitudinal studies were used. Principal component analysis and rel...
