Introducción: La artritis reumatoide es una enfermedad autoinmune de causas desconocidas en la que pueden influir distintas alteraciones genéticas. Se describen casos seropositivos con mayor riesgo de padecer manifestaciones extraarticulares y complicaciones de la enfermedad. Objetivo: Identificar la r...
Recent publications have investigated the potential role of the protein level of matrix metalloproteinase-1 (MMP-1) in the susceptibility to rheumatoid arthritis (RA) and osteoarthritis (OA). However, no unanimous conclusion was obtained. Therefore, we carried out a meta-analysis to explore the associati...
La autoinmunidad es la consecuencia de la pérdida de control y regulación de la respuesta inmune. Se re-porta que ocurre entre 5 y 9% de patologÃas a nivel mundial. A las enfermedades con esta anomalÃa se les denomina autoinmunes y se clasifican de acuerdo con el órgano o sistema afectado. Las reumÃ...
Rheumatoid arthritis is a clinical autoimmune syndrome that causes joint damage. The positive or negative anti-cyclic citrullinated protein (CCP) antibodies serodiagnosis differentiates two subsets of the disease, each with different genetic background. Previous studies have identified associations betwe...
Tumor necrosis factor-alpha (TNF-α) plays an important role in autoimmune diseases. Previous studies have investigated the association of TNF-α-238G/A (rs361525) and -308G/A (rs1800629) polymorphisms with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, no agreed concl...
The autoimmune regulator (AIRE), a transcriptional regulator expressed in medullary thymic epithelial cells, plays an important role in thymocyte education and negative selection. Several citations studying the association between the rs878081 exon polymorphism of the AIRE gene and the risk of rheumatoid...
This study was performed to examine whether the AF4/FMR2 family, member 1 (AFF1) rs340630 polymorphism is involved in the genetic background of rheumatoid arthritis (RA) in a Chinese population. Two different study groups of RA patients and controls (328 RA patients and 449 healthy controls in the first ...
La artritis reumatoide (AR) es una enfermedad sistémica crónica y autoinmune, que afecta principalmente a las articulaciones sinoviales. Al igual que ocurre con muchas enfermedades autoinmunes, la etiologÃa de la AR es multifactorial y desconocida. La susceptibilidad genética es evidente en AR, situa...

ABSTRACT Objective: This study aims to analyze the relationship of programmed cell death 1 (PDCD1) gene polymorphism (PD1.3G/A - rs11568821) with features of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) in a Southern Brazilian population. Methods: Polymerase chain reaction-restricti...
ABSTRACT Background: Rheumatoid arthritis is a widely prevalent autoimmune disorder with suggested genetic predisposition. Objectives: The aim of this study is to detect the pattern of genetic polymorphism of methylene tetrahydrofolate reductase (MTHFR C677 T and A1298 C), transforming growth factor-...
