Predictors of efficacy of ultrasound-guided intra-articular glucocorticoid injection in knee osteoarthritis: A prospective study.

Background: Intra-articular glucocorticoid injection (IAGI) is widely used for treatment of knee osteoarthritis (OA) flares. Response rates are generally around 70%. Several studies have tried to identify predictors of good response, but response to ultrasound (US)-guided injection has not yet been investigated.

Autoantibody profile in a cohort of Algerian patients with systemic sclerosis.

Aim: To describe the autoantibody profile in a cohort of Algerian patients with systemic sclerosis (SSc) and to determine clinical associations between SSc-related autoantibodies, disease subtypes and specific clinical features.

Methods: Consecutive Algerian patients with SSc were included in the present study. In addition to clinical characterization, all subjects underwent autoantibody testing using indirect immunofluorescence, immunoenzymatic, and line immunoblot assays.

Ankylosing spondylitis: analysis of gene-gene interactions between β, , and in Han Chinese and Algerian cohorts.

Introduction: Association studies have recently identified the importance of new genetic variants for ankylosing spondylitis (AS) in several populations. Our aim was to confirm associations of variants within genes involved in the IL-23 signalling pathway with AS in two ethnically different populations: Han Chinese and Algerian.

Material And Methods: Two case-control studies were performed in separate cohorts: Han Chinese (430 AS patients and 580 controls) and Algerian (130 AS patients and 120 controls).

The Prevalence of Non-radiographic Axial Spondyloarthritis Among Patients with Inflammatory Back Pain from Northwest and South Africa: Data from a Noninterventional, Cross-Sectional Study.

Introduction: Information is limited on the prevalence and clinical characteristics of nonradiographic axial spondyloarthritis (nr-axSpA) among patients with inflammatory back pain (IBP) in African countries. A global study estimated the prevalence of nr-axSpA among patients with IBP from 19 countries in Latin America, Europe, Asia, and Africa. This post hoc subset analysis focused on estimating prevalence of nr-axSpA and clinical characteristics among patients with IBP from Northwest Africa (Morocco and Algeria) and South Africa.

Prevalence of metabolic syndrome in Algerian rheumatoid arthritis patients. Correlation with disease activity and functional status.

Background: There is evidence that rheumatoid arthritis (RA) patients have an over-risk of cardiovascular disease. This may be mainly due to an increase in the prevalence of metabolic syndrome (MetS). The prevalence of MetS among adults in Algeria is 19.
