Method: We performed an observational cohort study including 100 patients with RA and control subjects. Serum levels of tumor markers carcinoembryonic antigen (CEA), cancer antigen (CA) 125, CA 19–9 and CA 15–3 were evaluated along with clinical and laboratorial RA data. Association tests between tumor markers levels and RA disease activity parameters were performed. Patients with abnormal tests were submitted to further investigation, including chest X-ray, colonoscopy, abdominal ultrasonography, upper gastrointestinal endoscopy and mammography, depending on the type of tumor marker that was elevated. Results: Patients Selumetinib mw with RA had high
levels of CEA and CA 19–9 more frequently than controls (P < 0.05). No correlation was found between tumor markers and RA disease activity assessed by the Disease Activity Score 28. Two neoplasms were found, but only one was related to high tumor marker (an ovarian carcinoma with high CA 125 levels). Conclusion: High tumor markers were frequently found in RA patients, even with controlled disease and were not related to actual cancer. Therefore, small increases of these markers in RA cases probably do not warrant a
search for an occult neoplasm. “
“High mobility group box 1 protein (HMGB1) is a proinflammatory cytokine. Previous studies have suggested that HMGB1 can play an important role in the pathogenesis of many rheumatic diseases. The purpose of this study was to investigate the serum levels of HMGB1 in patients with fibromyalgia (FM) and its association with quality of life and psychological phosphatase inhibitor library and functional status in these patients. Twenty-nine patients who met the 1990 American College of Rheumatology (ACR) criteria for the classification of FM
and 29 healthy controls (HC) were included in the present study. Serum samples were collected from both the patients and the HC, and HMGB1 levels were measured by enzyme-linked immunosorbent assay (ELISA). The Fibromyalgia Impact Questionnaire (FIQ) was used to assess the disease severity and functional status in patients with FM. Furthermore, the Nottingham Health Profile was used to assess quality of life in all subjects, as well as the Hospital Anxiety and Depression Scale (HADS) to assess depression and anxiety. The serum levels of HMGB1 protein were positively correlated with the FIQ scores in patients with FM (P = 0.002). Mean serum levels of Molecular motor HMGB1 were higher in patients with FM than in HC but this difference was not statistically significant. HMGB1 protein might be a good laboratory-sourced candidate for the assessment of functional status and disease severity in patients with FM. “
“To compare the frequency of osteoporosis and bone mineral density (BMD) below the expected range for age between female patients with rheumatoid arthritis (RA) and healthy subjects and to determine risk factors for bone loss in female patients with RA. Two hundred and ninety-nine patients with RA and 246 age-matched healthy subjects were included in this study.
