Product of aromatase activity in intact LNCaP and MCF-7 human cancer cells
1997
We investigated conversion rates of androgens to estrogens in cultured, hormone-responsive prostate (LNCaP) and breast (MCF-7) human cancer cells. For this purpose, we adopted an intact cell analysis, whereby cells were incubated for different incubation times in the presence of close-to-physiological (1 nM) or supraphysiological (1 μM) concentrations of labelled androgen precursors, i.e. testosterone (T) and androstenedione (Δ4Ad). The aromatase activity, as measured by estrogen formation, was detected in LNCaP cells (0.5 pmol/ml), even though to a significantly lower extent than in MCF-7 cells (5.4 pmol/ml), using 1 μM T after 72 h incubation. Surprisingly, LNCaP cells displayed a much hi…
THU0413 New Formulation with Potential for the Prevention and Treatment of Osteoporosis and Osteoarthritis
2013
Background Osteoarthritis (OA) is a multidimensional disease that affects all anatomical joint structures, particularly cartilage, synovium and subchondral bone. In turn, osteoporosis (OP) is a skeletal disorder characterized by a compromised bone strength which substantially increases the risk of fracture. Both are common disorders which affect quality of life in elderly. Despite this, there is not any drug at the moment for the simultaneous prevention and treatment of osteoporosis and osteoarthritis. Objectives The aim of this study was to investigate the effect of a new formulation in a combined rat model of OP and OA. The formulation (BIS076) contains Vitamin D3, Hydroxyapatite as a sou…
Inconsistency in circulating irisin levels: what is really happening?
2014
The discovery of irisin as a novel and promising peptidic hormone for the treatment of obesity and diabetes has recently been reported. As a result, great hopes have been raised based on this finding, hypothesizing that irisin might provide additional benefits, not only for obesity and diabetes, but also for a wide range of pathological conditions requiring therapeutical and clinical attention. However, controversial results and conclusions on circulating irisin concentrations and correlations with other variables, including its role in metabolism, have recently been reported. Although laboratory assessment of irisin by ELISA is easily available and may provide interesting information for t…
Regulation of Apoptosis in Endocrine Autoimmunity
2002
Dysregulation of apoptosis is associated with the pathogenesis of organ-specific autoimmune diseases, through altered target organ susceptibility. Apoptosis signaling pathways can be initiated through activation of death receptors such as Fas. A comparative analysis of the expression of Fas and FasL, the antiapoptotic molecule Bcl-2, and apoptosis in both thyrocytes and thyroid-infiltrating lymphocytes (TILs) from patients with either Graves' disease (GD) or Hashimoto's thyroiditis (HT) was performed. GD thyrocytes expressed less Fas than HT thyrocytes, whereas GD TILs had higher levels of Fas and FasL than HT TILs. GD thyrocytes expressed higher levels of Bcl-2 compared with HT thyrocytes.…
AB0996 Rheumathologic Diseases in Adolescence: Psychological Profile of a Difficult Age
2015
Background Chronic disease significantly interfere with the quality of life at every age, expecially in a period of life characterized by the need to assume a role in the society and the research of a specific identity. The personal image is often destroyed by the disease, the long term sequelae of pharmacological treatment. Adolescents are frequently obligated to quit many possibilities of experience with peers. Objectives We realized a plurispecialistic approach to adolescents with rheumatologic diseases, with the figures of neuropsychiatric, psychologists, rheumatologists, endocrinologists, to give an answer to the complex requests of these patients. Methods We evaluated 20 patients with…
SAT0136 Focus on Implementation of Cardiovascular Risk Factor Recording for Patients with Rheumatoid Arthritis in A Rheumatology Outpatient Clinic
2014
Objectives There is a need for implementing the knowledge of cardiovascular (CV) risk in patients with rheumatoid arthritis (RA) into clinical practice. Our aim was to evaluate CV risk factor (CVRF) recording in a rheumatology outpatient clinic (ROC), where the standard was annual CVRF recording. A second aim was to compare CVRF recording between a regular ROC (RegROC) and an arthritis clinic (AC), which consisted of a structured, team-based model. Methods In 2012, 1142 RA patients visited the ROC of the Hospital of Southern Norway. Of these 612 attended RegROC and 530 attended AC. We conducted a search in the patients9 hospital records to identify recording of CVRFs. Results CVRFs were rec…
AB0715 THE PREVALENCE OF FIBROMIYALGIA IN PATIENTS WITH FAMILIAL MEDITERRANEAN FEVER AND THE RELATIONSHIP BETWEEN FATIGUE AND QUALITY OF LIFE
2021
Background:Familial Mediterranean Fever (FMF) can cause various muscle diseases. Because it is a chronic auto inflammatory disease, painful trigger points may be encountered in the examination due to a decrease in the pain threshold (1-3).Objectives:The aim of this study was to determine the prevalence of Fibromiyalgia in patients with FMF, at the same time to identify the relationship between fatigue and quality of life.Methods:Sixtyseven patients (38 female, 29 male) with FMF were enrolled in the study. They were diagnosed with FMF based on the Livneh diagnostic criteria (4). Fibromyalgia involvement of the patients was evaluated according to the Fibromyalgia Impact Questionnaire (FIQ). P…
THU0573 Association Between Sosiodemogapic Data and Perceived Health Status on Sexual Activity in Patients with Axial Spondyloarthritis
2013
Background Axial spondyloarthritis (ax-SpA) is a chronic inflammatory disorder causing signs and symptoms from the axial skeleton, but may also affect peripheral joints, tendons and internal organs. Ax-SpA may give rise to significant loss of function and impaired quality of life. Despite the known importance of sexuality as part of quality of life (Healey 2009), only a few studies have explored sexuality in ax-SpA patients. Objectives To investigate the association between sosiodemograpic data and perceived health status on sexual activity in patients with ax-SpA. Methods Patients with ax-SpA (fulfilling the axial SpA criteria) were consecutively recruited from one clinic in southern and o…
THU0366 SYSTEMATIC CORONARY RISK EVALUATION (SCORE) MISCLASSIFIES CARDIOVASCULAR RISK IN ANTISYNTHETASE SYNDROME: RESULTS OF THE PILOT MULTICENTRIC S…
2020
Background:Antisynthetase Syndrom (ASyS) is an autoimmune overlap disease characterized by antiaminoacyl-tRNA-synthetase (anti-ARS) antibodies and the classic triad of arthritis, myositis and interstitial lung disease (ILD) (1). Markers of cardiovascular (CV) or cerebrovascular (CVB) risk have never been examined in ASyS.Objectives:Aim of this study (RIsk of CARdiovascular Disease in ASyS: RI.CAR.D.A.) was to test the ability of an established traditional CV risk prediction score (Systematic Coronary Risk Evaluation-SCORE) and its EULAR modified version (mSCORE) to identify ASyS patients at high CV risk. Moreover, we sought to examine for the first time associations of CV surrogate markers …
THU0598 Course and Predictors of Pain and Physical Functioning in Patients with HIP Osteoarthritis: Systematic Review
2015
Background Knowledge of risk factors of future pain and physical functioning can be used to inform patients with hip osteoarthritis (OA) on the likely course of their condition and to adapt treatment according to the prognosis. Objectives To systematically summarise the literature on (1) the course of pain and physical functioning and on (2) prognostic factors of future pain and physical functioning in patients with OA of the hip. Methods A search was conducted in PubMed, CINAHL, Embase, Psych-INFO, and SPORTDiscus up to January 2014. Relevant study characteristics were reviewed. Studies were scored for their quality and a qualitative data synthesis was performed. Results Of the twelve incl…
