OBJECTIVE To determine the genetic, clinical and serological characteristics of systemic sclerosis (SSc)-rheumatoid arthritis (RA) overlap syndrome. METHODS Clinical manifestations and immunolaboratory features of 22 SSc-RA patients were assessed. The HLA-DR genotype of the 22 SSc-RA patients determined by SSP-PCR was compared with that of 38 SSc(More)
OBJECTIVE High-dose chemotherapy followed by autologous haematopoietic stem cell transplantation (AHSCT) can be a salvage therapy for patients with severe, refractory systemic autoimmune diseases. The function of the newly rebuilt immune system is important, but little is known about immune reconstitution after AHSCT in autoimmune disorders. Our aim was to(More)
Vitamin D deficiency may contribute to pathological changes in the number and function of CD4+ T helper cell subsets (CD4+Th1, CD4+Th17, CD4+CD25(bright)Foxp3-natural regulatory T cells-nTreg) in patients with undifferentiated connective tissue disease (UCTD). The aim of the present study was to evaluate, whether alfacalcidol could restore immune-regulatory(More)
OBJECTIVES The aim of the present study was to evaluate the vitamin D status in patients with mixed connective tissue disease (MCTD) and to determine which clinical symptoms, laboratory parameters and endothelial cell markers are associated with low vitamin D levels. METHODS 125 female MCTD patients and 48 age- and sex-matched healthy controls were(More)
BACKGROUND Regulatory T cells (Tregs) have an essential role in tolerance and immune regulation. However, few and controversial data have been published to date on the role and number of these cells in atopic dermatitis (AD). OBJECTIVES To investigate the number of CD4+CD25+FOXP3+ Tregs and interleukin 10-producing T regulatory type 1 (Tr1) cells in(More)
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by increased pathologic autoantibody production. A decrease in the number of CD4+CD25(high)FoxP3+ regulatory T cells can play a key role in the loss of tolerance to self antigens. Our aim was to determine the absolute number of peripheral CD4+CD25(high)FoxP3+ T cells in 44(More)
Targeted immuno-chemotherapy resulted in greatly improved survival of B cell lymphoma patients. Several prognostic markers are investigated, amongst them the pretreatment absolute lymphocyte numbers. We investigated lymphocyte subpopulations and correlated this data with prognosis of patients. 88 patients (mean age: 56 years, 18-88, median follow up 32(More)
OBJECTIVE The aim of the present study was to investigate the immunomodulating role of fat-soluble vitamins in 25 patients with primary SS (pSS) and 15 healthy individuals. METHODS Plasma levels of vitamins A, D and E were determined by HPLC. Peripheral NK, NK T cells, T-cell subsets, B cells, IL-10 producing Tr1 cells, CD4(+)CD25(+) Treg cells and Th17(More)
Exposure to particulate matter and ozone cause adverse airway reactions. Individual pollutant effects are often addressed separately, despite coexisting in ambient air. The present investigation was performed to study the effects of sequential exposures to diesel exhaust (DE) and ozone on airway inflammation in human subjects. Healthy subjects underwent(More)
Naïve and memory B- and T-cell subsets were examined with three-color flow cytometry in the peripheral blood of patients with rheumatoid arthritis (RA) in comparison with healthy controls, and their association with disease duration, activity and autoantibodies was investigated in order to reveal potential imprints of antigen-specific immune response in RA.(More)
