Autoantibody profile in juvenile chronic arthritis.

Antinuclear antibodies and juvenile chronic arthritis (JCA): search for a specific autoantibody associated with JCA.

Elevated IgG autoantibody production in oligoarticular juvenile idiopathic arthritis may predict a refractory course.

OBJECTIVES Although oligoarticular juvenile idiopathic arthritis (oJIA) is considered to carry the best prognosis among the JIA subtypes, many children evolve to a chronic course. A few studies have identified clinical risk factors for disease extension, and recent studies have evaluated synovial fluid markers. However, the only biological marker from the serum studied to date is the anti-nucle...

Juvenile Idiopathic Arthritis Onset in a Neonate: A Rare Case Report

Background: A common type of chronic arthritis in children and adolescents is juvenile idiopathic arthritis (JIA).According to the International League of Associations for Rheumatology (ILAR) classification, JIA diagnostic criteria include age under 16 years and disease duration of six-weeks. Based on the number of involved joints in the first sixmonths of disease onset, JIA is categorized into...

Autoantibodies in juvenile-onset myositis: Their diagnostic value and associated clinical phenotype in a large UK cohort

OBJECTIVES Juvenile myositis is a rare and heterogeneous disease. Diagnosis is often difficult but early treatment is important in reducing the risk of associated morbidity and poor outcomes. Myositis specific autoantibodies have been described in both juvenile and adult patients with myositis and can be helpful in dividing patients into clinically homogenous groups. We aimed to explore the uti...

COPD is associated with production of autoantibodies to a broad spectrum of self-antigens, correlative with disease phenotype.

The role of autoimmune pathology in development and progression of chronic obstructive pulmonary disease (COPD) is becoming increasingly appreciated. In this study, we identified serum autoantibody reactivities associated with chronic bronchitis or emphysema, as well as systemic autoimmunity and associated lung disease. Using autoantigen array analysis, we demonstrated that COPD patients produc...
