UNLABELLED Ankylosing spondylitis (AS) is characterized by inflammation of the entheses and paravertebral structures, leading in time to bone formation at those sites. As well, vertebral bone loss is also a recognized feature of AS Objective: To calculate the prevalence and risk factors of osteoporosis and vertebral fractures in patients with AS. METHODS(More)
Bone mineral density (BMD) measurements are frequently performed repeatedly for each patient. Subsequent BMD measurements allow reproducibility to be assessed. Previous studies have suggested that reproducibility may be influenced by age and clinical status. The purpose of the study was to examine the reproducibility of BMD by dual energy X-ray(More)
Bone mineral density (BMD) measurements using dual-energy X-ray absorptiometry (DXA) are widely used to diagnose osteoporosis and assess its severity. Previous studies show the necessity to establish reference data for bone mass measurements for each particular population. Such data are lacking for the Moroccan population. The aim of this study was to(More)
The recently completed European trial of interferon beta-had a greater reduction of cerebral volume in the placebo group (mean reduction at month 36: placebo 5.1%, IFNβ-1b (IFNβ-1b) in patients with secondary progressive 1b 1.8%, P < 0.05) whereas those with Gd-enhancing multiple sclerosis (SP multiple sclerosis) has given an lesions showed a trend to(More)
Osteoarthritis (OA) of the knee is the most common form of arthritis. A positive association between obesity and several occupational factors and knee OA has been observed in previous studies in populations of different ethnicity. The aim of this study was to examine the relation between knee OA and body weight and occupational factors in a Moroccan sample(More)
Due to its low cost, portability, and nonionizing radiation, quantitative ultrasound (QUS) of the heel is an alternative to the measurement with dual X-ray absorptiometry (DXA) in the evaluation of bone status. The objective of the study is to compare in asymptomatic postmenopausal women the ability of QUS and DXA to discriminate between those with and(More)
The aim of this study was to test bone mineral density (BMD), trabecular bone score (TBS), and their combination, for detection of rheumatoid arthritis (RA) patients with vertebral fractures (VFs). One hundred eighty-five women aged 56.0 ± 13.5 yr, with RA since 15.5 ± 9.9 yr were studied. Lumbar spine, total hip, and femoral neck BMD were assessed by(More)
Introduction Measuring bone mineral density (BMD) is a widely accepted strategy for identifying subjects with an increased risk of fracture. However, because of limited availability of BMD technology in some communities and cost considerations, it has been proposed that BMD measurements be targeted to subjects with risk factors for osteoporosis. Recently,(More)
BACKGROUND Diagnostic discordance for osteoporosis is the presence of different categories of T-scores in 2 skeletal sites of an individual patient, falling into 2 different diagnostic categories identified by the World Health Organization classification system. OBJECTIVES To evaluate the prevalence and risk factors for T-score discordance between spine(More)
Specific antagonists of tumour necrosis factor (TNF-alpha) have rapidly gained popularity for the treatment of rheumatoid arthritis and ankylosing spondylitis (AS). Reported side effects from these agents include drug-induced autoimmune disorders. The monoclonal antibody against TNF-alpha, infliximab, has been associated with induction of systemic lupus(More)
