UNLABELLED OBJECTIVE-METHODS: Adamantiades-Behcet disease (ABD) is a multi-systemic vasculitis of unknown origin, with a characteristic geographic distribution, that affects vessels of all kinds and sizes and is characterized by recurrent mucosal, skin and ocular lesions. In the present study, a series of 36 patients from Northern Greece is analyzed(More)
OBJECTIVES Regulatory T cells (Tregs) are inversely correlated to disease activity in systemic lupus erythematosus (SLE). However, little is known concerning the influence of immunosuppressive agents on Tregs, which was the objective of this study. METHOD Thirty-five patients with SLE (29 females, six males, mean age 42.4 ± 12.8 years) were included.(More)
A 43 year old female patient presented for recurrent bacterial lower respiratory infections. A research for immunodeficiency status revealed total hypogammaglobulinemia, reduced IgG1, IgG2, IgG3 subclass levels, and low number of B lymphocytes (CD19+). Common Variable Immunodeficiency (CVID) 11.2 category was diagnosed according to recent criteria of(More)
Environmentally induced systemic sclerosis is a well-recognized condition, which is correlated with exposure to various chemical compounds or drugs. However, development of scleroderma-like disease after exposure to silicone has always been a controversial issue and, over time, it has triggered spirited debate whether there is a certain association or not.(More)
AIM To present the characteristics and the course of a series of anti-hepatitis B virus core antibody (HBc) antibody positive patients, who experienced hepatitis B virus (HBV) reactivation after immunosuppression. METHODS We retrospectively evaluated in our tertiary centers the medical records of hepatitis B virus surface antigen (HBsAg) negative patients(More)
ml) were detected in 11/35 patients (31.4%), 7 with IgG anti-PS/PT, 1 with IgM anti-PS/ PT, and 3 with concomitant IgM and IgG anti-PS/PT. From these patients, seven had a recent history of vascular thrombosis, while the remaining four had other aPL-related symptoms and end-stage renal disease (1/11), recurrent serositis (2/11), and false positive(More)
To clarify the role of ADAMTS-13 in the pathogenesis of thrombotic microangiopathy in systemic lupus erythematosus (SLE) we evaluated ADAMTS-13 profile (metalloprotease antigen levels, anti-ADAMTS-13 autoantibody levels, activity) in distinct patient groups according to disease activity, extent of cumulative tissue damage and history of antiphospholipid(More)
Chronic brucellosis patients display a defective Th1 response to PHA. We have previously shown that heat-killed B. abortus (HKBA) can downregulate the PHA-induced increase of CD4+/CD25+ and CD14+/CD80+ cells of brucellosis patients. In the present study, we investigate the effect of E. coli LPS, as a potent stimulant of monocytes and autologous(More)
