The Fibromyalgia Impact Questionnaire (FIQ) is a commonly used instrument in the evaluation of fibromyalgia (FM) patients. Over last 18 years, since publication original FIQ, several deficiencies have become apparent and cumbersome scoring algorithm has been barrier to widespread clinical use. aim this paper describe validate revised version FIQ: FIQR.The FIQR was developed response known FIQ with help patient focus group. same 3 domains as (that is, function, overall impact symptoms).

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that characterized by defective immune tolerance combined with cell hyperactivity resulting in the production of pathogenic autoantibodies. Previous gene expression studies employing whole blood or peripheral mononuclear cells (PBMC) have demonstrated majority patients active increased type I interferon (IFN) inducible transcripts known as IFN signature. The goal current study was to assess profiles isolated leukocyte subsets...

Objectives To investigate whether biomarkers related to B cell activation and autoantibody production are associated with the response abatacept in rheumatoid arthritis (RA) patients. Methods Twenty-five patients RA were enrolled this study. Responders (n=10) subjects who achieved ACR50 at week 24. Serum levels of soluble measured ProcartaPlex by Luminex or ELISA.

TNF inhibitors have been used as a treatment for moderate to severe RA patients. However, reliable biomarkers that predict therapeutic response are lacking. In this study, we investigated whether chemokines may represent useful the inhibitor therapy in RA.RA patients (n = 29) who were initiating adalimumab or etanercept recruited from rheumatology clinics at Cooper University Hospital. evaluated baseline and 14 weeks after therapy, serum levels of CXCL10, CXCL13, CCL20 measured by ELISA....

Systemic lupus erythematosus (SLE) is characterized by loss of immune tolerance. A hallmark SLE the presence autoantibodies resulting from B cell hyperactivity. Previous studies have shown that abnormal subsets in periphery, such as CD27highCD20- cells, correlate with disease activity. We examined relationship between expression CD70, ligand for CD27 expressed activated T and indicators significant increase median CD70+CD4+ frequencies memory CD45RA-CD4+ was observed samples compared to...

Objective. CD70-expressing CD4 T cells are enriched in RA and promote autoimmunity via co-stimulatory CD70-CD27 interaction. This study aimed to explore the phenotype cytokine production of CD70+ RA. Methods. Peripheral blood mononuclear from 32 patients were isolated frequencies within different subsets analysed using flow cytometry. IFN-γ IL-17 compared between CD70− cells. Expression master transcription factors T-bet, GATA3 retinoic acid–related orphan receptor gamma t (RORγt) examined...

Despite the importance of early detection glaucoma, most patients with progressive glaucoma show minimal symptoms. We aimed to evaluate biomarkers for diagnosis in Korea. Forty-two volunteers with/without open-angle were enrolled from January through October 2015—divided into a control or group, which was further divided normal-tension (NTG) and high-tension (HTG) groups—and underwent assessments myelin basic protein (MBP), heat shock 60, anti-Sjögren’s-syndrome-related antigen A (SSA) B...

In Brief Polyarteritis nodosa (PAN) is a vasculitis of small- and medium-sized vessels, characterized by vascular aneurysms that can lead to ischemia infarction. We present the case patient with classic polyarteritis in abdominal organs who additionally demonstrated antitreponemal antiphospholipid antibodies, resulting severe cerebral thrombosis. This highlights: 1. The potential for false-positive syphilis serology PAN patients, 2. rare coexistence catastrophic syndrome. occasional...
