Urolithiasis in ankylosing spondylitis: Correlation with Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis metrology index (BASMI)
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...
متن کاملASSOCIATION OF HLA-B27 WITH ANKYLOSING SPONDYLITIS IN ISFAHAN, IRAN
Using a standard microcytotoxicity (NIH) technique of tissue typing, the HLA-B27 antigen was identified in 30 out of 34 patients (HH.2%) with classical ankylosing spondylitis (AS), compared to 6 out of 70 controls (H.6%) (P < 0.005). We also found this antigen in 8 out of 76 (10.5%) patients with non-AS arthritis.
متن کاملMethods for Population-Adjusted Indirect Comparisons in Health Technology Appraisal
Standard methods for indirect comparisons and network meta-analysis are based on aggregate data, with the key assumption that there is no difference between the trials in the distribution of effect-modifying variables. Methods which relax this assumption are becoming increasingly common for submissions to reimbursement agencies, such as the National Institute for Health and Care Excellence (NIC...
متن کاملNormative values for the bath ankylosing spondylitis functional index in the general population compared with ankylosing spondylitis patients in Morocco
BACKGROUND The Bath Ankylosing Spondylitis Functional Index (BASFI) has been commonly used in rheumatology to quantify functional disability in patients with ankylosing spondylitis (AS). Our aim was to evaluate the discriminating power of BASFI and determine the best cutoff score of this index in the general population compared with AS patients. METHODS A cross-sectional study that included 2...
متن کاملFrequency of cardiac involvement among patients with Ankylosing Spondylitis
Background and aims: Ankylosing spondylitis (AS) is an idiopathic chronic inflammatory disease mainly involves sacroiliac and axial joints; but it may also have extra-articular involvement. Accordingly, this study was designed to determine the frequency of cardiac involvement among patients with ankylosing spondylitis. Methods: This study was performed as a descriptive-analytical cross-se...
