OBJECTIVE Findings from previous studies have suggested that subclinical inflammation of the synovium does not coincide with the appearance of rheumatoid arthritis (RA)-specific autoantibodies. This study was undertaken to examine the relationship between the presence of autoantibodies, changes in the synovium, and development of arthritis over time in a(More)
OBJECTIVE The presence of antibodies against cyclic citrullinated peptides has been demonstrated to precede the onset of symptoms of rheumatoid arthritis (RA) by several years. The aim of this study was to analyze antibodies against 10 citrullinated autoantigen-derived peptides for reactivity before the onset of RA symptoms. METHODS A case-control study(More)
INTRODUCTION Overexpression of epidermal growth factor receptor (EGFR) is a prognostic and predictive biomarker in a number of malignant tumours. Radionuclide molecular imaging of EGFR expression in cancer could influence patient management. However, EGFR expression in normal tissues might complicate in vivo imaging. The aim of this study was to evaluate if(More)
INTRODUCTION It has previously been shown that an increased number of antibodies against citrullinated peptides/proteins (ACPA) predate the onset of rheumatoid arthritis (RA). Over time antibody positivity expands, involving more specific responses when approaching the onset of symptoms. We investigated the impact of human leukocyte antigen-shared epitope(More)
INTRODUCTION Autoantibodies directed against citrullinated proteins/peptides (ACPAs) are highly specific and predictive for the development of rheumatoid arthritis (RA). Different subgroups of RA patients, which have different prognoses and may require different treatments, are characterized by different autoantibody profiles. The objective of this study(More)
UNLABELLED Overexpression of the human epidermal growth factor receptor type 2 (HER2) in breast carcinomas predicts response to trastuzumab therapy. Affibody molecules based on a nonimmunoglobulin scaffold have demonstrated a high potential for in vivo molecular imaging of HER2-expressing tumors. The reengineering of the molecular scaffold has led to a(More)
OBJECTIVE To investigate the role of genetic and environmental factors in the development of anticitrullinated protein antibodies (ACPA) and ACPA-positive rheumatoid arthritis (RA) in a twin cohort. METHODS A total of 12 590 twins were analysed for the presence of ACPAs (CCP2 ELISA), HLA-DRB1 shared epitope (SE) gene alleles, and exposure to smoking.(More)
OBJECTIVES X-ray fluorescence (XRF) is a non-invasive method for determining the iodine content of the thyroid gland in vivo. In spite of the obvious clinical value of such a method in situations of iodine deficiency or iodine overload, the method has not so far been widely used. The objective was to investigate the applicability of the XRF method in a(More)
PURPOSE Overexpression of the HER2 receptor is a biomarker for predicting those patients who may benefit from trastuzumab therapy. Radiolabelled Affibody molecules can be used to visualize HER2 expression in tumour xenografts with high sensitivity. However, previous studies demonstrated that the difference in uptake in xenografts with high and low HER2(More)
BACKGROUND/OBJECTIVES Sweden has a long-standing salt iodization program; however, its effects on iodine intake have never been monitored on a national level. The objective of this study was to evaluate iodine nutrition in the Swedish population by measuring the urinary iodine concentration (UIC) in a national sample of Swedish school-age (6-12 years of(More)
