Independence of carbohydrate-deficient isoforms of transferrin and cyclic citrullinated peptides in rheumatoid arthritis

Rev. bras. reumatol; 57 (3), 2017
ABSTRACT Objective: The aim of this study was to assess the relationship between the two types of posttranslational modifications of proteins in RA: glycosylation on the example of carbohydrate-deficient transferrin and citrullination by means of autoantibodies to cyclic citrullinated peptides. Methods...

Unbalanced expression of aryl hydrocarbon receptor in peripheral blood CCR6+CD4+ and CD4+CD25+T cells of rheumatoid arthritis

Rev. bras. reumatol; 57 (3), 2017
ABSTRACT Objective: The goal of this study was to analyze the role of aryl hydrocarbon receptor in peripheral blood CCR6+CD4+ and CD4+CD25+T cells of patients with rheumatoid arthritis. Methods: Flow cytometry was applied to determine the proportion of AhR positive cells in CCR6+CD4+T, CD4+CD25+T and p...

Anti-CCP antibodies are not a marker of severity in established rheumatoid arthritis: a magnetic resonance imaging study

Rev. bras. reumatol; 57 (1), 2017
ABSTRACT Introduction: The presence of anti-CCP is an important prognostic tool of rheumatoid arthritis (RA). But research is still ongoing on its relationship with disease activity and functional capacity. Objectives: To study the relationship between anti-CCP and disease activity, functional capacity...

IL33 in rheumatoid arthritis: potential contribution to pathogenesis

Rev. bras. reumatol; 56 (5), 2016
ABSTRACT A better understanding of the inflammatory mechanisms of rheumatoid arthritis and the development of biological therapy revolutionized its treatment, enabling an interference in the synovitis – structural damage – functional disability cycle. Interleukin 33 was recently described as ...

Overlap between systemic sclerosis and rheumatoid arthritis: a distinct clinical entity?

Rev. bras. reumatol; 56 (4), 2016
ABSTRACT Introduction: Systemic sclerosis (SSc) is an autoimmune disease of the connective tissue characterized by the triad of vascular injury, autoimmunity (cellular and humoral) and tissue fibrosis. It is estimated that musculoskeletal pain is a common complaint of patients with SSc, ranging from 40 ...

Familial autoimmunity and polyautoimmunity in 60 Brazilian Midwest patients with systemic sclerosis

Rev. bras. reumatol; 56 (4), 2016
ABSTRACT Introduction: Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a giv...

Determinación de haplotipos clase II del complejo principal de histocompatibilidad en pacientes del sexo masculino con artritis reumatoide
Association between antigens class II and masculine rheumatoid arthritis

Rev. mex. reumatol; 13 (4), 1998
Objetivo: La artritis reumatoide (AR) es una enfermedad multifactorial y sistémica del tejido conjuntivo. Caracterizada por afección simétrica de las articulares pequeñas de las manos y pies, en etapas tardías puede también involucrar articulaciones mayores. La afección es dada básicamente por un...

Anticuerpos anticitoplasma de los neutrófilos (ANCA) en artritis reumatoide (AR)
Antineutrophils cytoplasmic antibodies in rheumatoid artritis

Rev. mex. reumatol; 10 (5), 1995
Los anticuerpos anticitoplasma de los neutrófilos (ANCA) son anticuerpos dirigidos contra componentes del citoplasma de los neutrófilos y monocitos. Por inmunofluorescencia indirecta (IFI) se distinguen dos patrones: p-ANCA y c-ANCA, los cuales se han relacionado con diferentes tipos de vasculitis. En ...

Interacción de la interleucina-6 y el factor de necrosis tumoral- Ó con la proteína C-reactiva y el amiloide sérico en el proceso inflamatorio de la artritis reumatoide
Interactions of OL-6 and TNF in the production of acute phase proteins in rheumatoid arthritis

Rev. mex. reumatol; 9 (4), 1994
Se revisa la importancia de IL6 y TNF en la producción de proteínas reactantes de fase aguda y sus posibles interacciones en el proceso inflamatorio en artritis reumatoide, donde la membrana sinovial, es infiltrada por células, y los macrófagos producen IL-1, TNF-Ó e IL-6. La secreción local de cit...
