Circular RNAs Hsa_circ_0002715 and Hsa_circ_0035197 in Peripheral Blood Are Novel Potential Biomarkers for New-Onset Rheumatoid Arthritis.

This study is aimed at exploring the levels of peripheral blood circular RNAs (circRNAs) as biomarker candidates for the diagnosis of new-onset rheumatoid arthritis (RA). The selected twenty-two circRNAs in peripheral blood from new-onset RA patients and healthy controls (HC) were determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The levels of hsa_circ_0002715, hsa_circ_0001947, hsa_circ_0000367, and hsa_circ_0035197 were significantly increased in the peripheral blood of new-onset RA patients than in the peripheral blood of HC. And, there were obvious differences in the above four peripheral blood circRNAs between new-onset RA patients and systemic lupus erythematosus (SLE) patients and ankylosing spondylitis (AS) patients. Moreover, there were obvious differences in hsa_circ_0001947 and hsa_circ_0035197 between new-onset RA patients and patients with undiagnosed arthritis (UA). Receiver operating characteristic (ROC) curve analysis suggested that the levels of hsa_circ_0002715 and hsa_circ_0000367 in peripheral blood could distinguish new-onset RA patients from the HC, AS patients, and SLE patients, and the levels of hsa_circ_0001947 and hsa_circ_0035197 in peripheral blood could distinguish new-onset RA patients from the HC, AS patients, SLE patients, and UA patients. The logistic regression model showed that the combination of hsa_circ_0002715 and hsa_circ_0035197 could provide the best diagnostic accuracy with an area under the curve (...

AbstractObjectivesTo evaluate and compare the clinical implications of common inflammatory markers in systemic rheumatic diseases (SRDs).MethodWe investigated the profiles of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count in treatment-na ïve patients with SRDs, osteoarthritis and pneumonia diagnosed at Seoul National University Hospital during 2004–2016. SRDs included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM) and adu lt-onset Still’s disease (AO...

r T Abstract BACKGROUND: Cytokines and associated intracellular signal cascades play a major role in the pathogenesis of autoimmune diseases. Janus kinases (JAK) are part of these intracellular signal transduction processes. A relatively new drug group of targeted synthetic disease-modifying antirheumatic drugs (tsDMARD) are JAK inhibitors (JAKi) and are a promising treatment approach for autoimmune diseases. EFFICACY: Hitherto, three JAKis, Tofacitinib, Baricitinib and Upadacitinib, have been approved for treatment of Rheumatoid Arthritis (RA) in the USA, Switzerland and the EU. Filgotinib, an...

In this study, 11 circRNAs (hsa_circ_0000479, hsa_circ_0002316, hsa_circ_0000317, hsa_circ_0082688, hsa_circ_0082689, hsa_circ_0087798, hsa_circ_0008529, hsa_circ_0000787, hsa_circ_0021727, hsa_circ_0000175, and hsa_circ_0003694) which were found to be significantly up-regulated in both peripheral blood mononuclear cells (PBMCs) from SLE patients in our previous study, and T cells from SLE patients in previous literature, were chosen for validation by quantitative reverse transcription-polymerase chain reaction in PBMCs from 50 new-onset SLE patients, 24 new-onset rheumatoid arthritis (RA) patients, 24 new-onset ankylosing...

Abstract Circular RNAs (circRNAs) are a novel class of RNAs that may be used as biomarkers in clinical blood samples. However, the role of circRNAs in rheumatoid arthritis (RA) has not been extensively investigated. In the present study, six circRNAs, including hsa_circ_0082689, hsa_circ_0087798, hsa_circ_0000175, hsa_circ_0008410, hsa_circ_0049356 and hsa_circ_0032959 levels were determined in peripheral blood mononuclear cells (PBMCs) collected from 24 patients with RA and 24 healthy controls (HC) by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis. Hsa_circ_0000175 and hsa_cir...

Authors: El Jammal T, Gerfaud-Valentin M, Sève P, Jamilloux Y Abstract In the past ten years, the better understanding of the pathophysiological mechanisms underlying inflammatory and autoimmune diseases has led to the emergence of many targeted therapies. Among them, the Janus kinase inhibitors are acting upstream in the inflammatory cascade of several key cytokines in disorders such as rheumatoid arthritis, ulcerative colitis or psoriasis. At the moment, these three diseases represent the only indications validated by the FDA and the EMA of the use of JAK inhibitors apart from hematology. Preclinical data ...

ConclusionThe eye could be a responsive marker for the onset or aggravation of an immune reactivation in many rheumatic diseases, furthermore, ocular findings can antedate the diagnosis of the underlying rheumatic disease. By recognizing ocular manifestations of systemic rheumatic diseases it might be possible to avoid or at least delay many long term sequelae.

CONCLUSION: Our study confirmed that general risk algorithms mostly underestimate and at times overestimate cardiovascular risk in rheumatic patients. We did not find studies that evaluated models for psoriasis or AS, which further demonstrates a need for research in these populations. PMID: 31416923 [PubMed - as supplied by publisher]

ConclusionAnti-DFS70 antibody was more prevalent in the subsets of SARD than BD. This result may be related to the demographic formation of study groups and individual immunological status. More comprehensive studies are needed to investigate the importance of the anti-DFS70 antibody for SARD.Key Points• This study draws attention to the importance of anti-DFS70 antibodies in the diagnostic algorithm in systemic autoimmune rheumatic diseases.• This study emphasizes the further investigation of anti-DFS70 antibodies in undifferentiated connective tissue diseases.• This study emphasizes the need to verify the ...

Purpose of review Sarcoidosis is an immune-mediated disease of unknown cause. Immune-mediated diseases appear to cluster in patients and in families. We review what is known on this topic for sarcoidosis, and what factors may underlie disease clustering. Recent findings In populations of patients with sarcoidosis, relative risk estimates of Sjögren's syndrome, systemic lupus erythematosus, autoimmune hepatitis, ankylosing spondylitis, multiple sclerosis (MS), celiac disease, autoimmune thyroid disease, and ulcerative colitis, varied between 2.1 and 11.6. In relatives of patients with sarcoidosis, relative risk es...
