B-cell activating factor and related genetic variants in lupus related atherosclerosis.

Background: Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease with an increased atherosclerotic risk compared to healthy population, partially explained by traditional cardiovascular (CV) risk factors. Recent data suggest B-cell activating factor (BAFF) as an important contributor in the pathogenesis of both SLE and atherosclerosis. The aim of the current study is to explore whether serum BAFF levels along with variants of the BAFF gene increase lupus related atherosclerotic risk.

Psychological comorbidities associated with subclinical atherosclerosis in Greek patients with primary Sjögren's syndrome: a potential contribution of sleep impairment.

Objectives: Impaired sleep and psychological disorders are increasingly recognised as prevalent comorbidities in patients with primary Sjögren's syndrome (pSS), as well as important contributors of atherosclerosis in the general population. In the current study we sought to explore a potential role of psychological comorbidities in the pronounced atherosclerotic risk of pSS patients.

Methods: Fifty-nine pSS patients fulfilling the ACR/EULAR criteria completed specific validated questionnaires assessing fatigue, depression, anxiety and sleep disturbances.

Flow cytometry analysis of CD4+IFN-γ+ T-cells for the diagnosis of mycobacterium tuberculosis infection.

Background: CD4+ cells expressing Interferon-γ (IFN-γ), following stimulation with specific mycobacterial antigens, identified with flow cytometry (FCM-CD4+IFN-γ+), is a new method for the diagnosis of Mycobacterium tuberculosis (MTB) infection. The aim of this study is to investigate the performance of FCM-CD4+IFN-γ+ in comparison with tuberculin skin test (TST) and Quantiferon TB Gold In-Tube (QFT-G-IT) in the diagnosis of latent MTB infection (LTBI), in close contacts and in patients with rheumatic diseases under treatment with anti-TNFa and other biologic agents.

Methods: TST, QFT-G-IT, and FCM-CD4+IFN-γ+ were performed in 56 immunocompetent close contacts and in 65 medically immunosuppressed patients under biologic treatment.

Subclinical atherosclerosis and impaired bone health in patients with primary Sjogren's syndrome: prevalence, clinical and laboratory associations.

Introduction: To determine the prevalence and clinical/laboratory associations of subclinical atherosclerosis and impaired bone health in primary Sjogren's syndrome (SS).

Methods: 64 consecutive patients with primary SS, 77 with rheumatoid arthritis (RA) and 60 healthy controls (HC) οf similar age and sex distribution were enrolled. Demographics, clinical/laboratory features, classical risk factors for atherosclerosis and osteoporosis (OP) were recorded.

Barriers to accessing biologic treatment for rheumatoid arthritis in Greece: the unseen impact of the fiscal crisis--the Health Outcomes Patient Environment (HOPE) study.

The latest regulatory change in the distribution system of biologic disease-modifying, antirheumatic drugs limited their sale only through the designated pharmacies of the National Organization for Healthcare Services Provision (EOPYY) or the National Health System (NHS) hospitals, adding to the complexity of access to effective treatment for rheumatoid arthritis (RA) in Greece. The aim of this paper was to assess the barriers to access RA treatment, by recording patients', rheumatologists' and EOPYY pharmacists' experiences. One twenty-three patients, 12 rheumatologists and 27 pharmacists from Athens and other urban areas in Greece participated in the study.

B-cell activating factor genetic variants in lymphomagenesis associated with primary Sjogren's syndrome.

Primary Sjogren's syndrome (pSS) is complicated by B-cell lymphoma in 5-10% of patients. Several clinical and serological features are proposed as adverse predictors for such complication and define a high risk pSS phenotype. We aimed to explore whether previously described polymorphisms of the B-cell activating factor (BAFF) could be related to pSS-related lymphomagenesis.
