BACKGROUND Recent data indicate increasing rates of adult obesity and mortality from cardiovascular disease (CVD) in Greece. No data, however, are available on prevalence of overweight and obesity in relation to CVD risk factors among young adults in Greece. METHODS A total of 989 third-year medical students (527 men, 462 women), aged 22 +/- 2 years, were(More)
Individuals with Behçet's disease suffer from episodic inflammation often affecting the orogenital mucosa, skin and eyes. To discover new susceptibility loci for Behçet's disease, we performed a genome-wide association study (GWAS) of 779,465 SNPs with imputed genotypes in 1,209 Turkish individuals with Behçet's disease and 1,278 controls. We identified new(More)
BACKGROUND Gene profiling studies provide important information for key molecules relevant to a disease but are less informative of protein-protein interactions, post-translational modifications and regulation by targeted subcellular localization. Integration of genomic data and construction of functional gene networks may provide additional insights into(More)
OBJECTIVES To develop recommendations for the management of adult and paediatric lupus nephritis (LN). METHODS The available evidence was systematically reviewed using the PubMed database. A modified Delphi method was used to compile questions, elicit expert opinions and reach consensus. RESULTS Immunosuppressive treatment should be guided by renal(More)
INTRODUCTION Bone marrow (BM) is an immunologically privileged site where activated autoantibody-producing B cells may survive for prolonged periods. We investigated the effect of rituximab (anti-CD20 mAb) in peripheral blood (PB) and BM B-cell and T-cell populations in active rheumatoid arthritis (RA) patients. METHODS Active RA patients received(More)
INTRODUCTION Prevalence of insulin resistance and the metabolic syndrome has been reported to be high in rheumatoid arthritis (RA) patients. Tumor necrosis factor (TNF), a pro-inflammatory cytokine with a major pathogenetic role in RA, may promote insulin resistance by inducing Ser312 phosphorylation (p-Ser312) of insulin receptor substrate (IRS)-1 and(More)
Use the epidemiology and natural history of • systemic lupus erythematosus (SLE) to inform diagnostic and therapeutic decisions Describe and explain the key events in the • pathogenesis of SLE and critically analyse the contribution of genetics, epigenetics, hormonal, and environmental factors to the immune aberrancies found in the disease Explain the key(More)
BACKGROUND Folate has emerged as a key nutrient for optimising health. Impaired folate status has been identified as a risk factor for cardiovascular disease, various types of cancers, and neurocognitive disorders. The study aimed at examining the distribution and determinants of serum folate concentrations in a healthy adult population in Crete, Greece. (More)
This is a report of a 12-year-old epileptic child undergoing chronic treatment with carbamazepine who was found comatose. He was considered to have acute severe drug toxicity. Measurement of carbamazepine concentration in the patient's hair segments together with the carbamazepine blood levels were both important in determining the chronic nature of the(More)
INTRODUCTION Interleukin-1β (IL-1β) is a major inflammatory cytokine, produced predominantly by innate immune cells through NLRP3-inflammasome activation. Both intrinsic and extrinsic danger signals may activate NLRP3. Genetic variations in NLRP3-inflammasome components have been reported to influence rheumatoid arthritis (RA) susceptibility and severity.(More)
