INTRODUCTION Both experimental and clinical data provide evidence that vitamin D is one of those important environmental factors that can increase the prevalence of certain autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, insulin-dependent diabetes mellitus, and inflammatory bowel disease. The aim of the present study was to(More)
The aim of this study was to evaluate the clinical and immunomodulatory effects of extracorporeal photochemotherapy (ECP) in systemic sclerosis (SSc). We enrolled 16 patients with diffuse cutaneous SSc, who received 12 ECP treatments in total. After ECP treatments, the dermal thickness reduced and the mobility of joints improved. Internal organ involvement(More)
Hyper-IgE syndrome (HIES) is a severe primary immunodeficiency, characterized by increased serum IgE levels as well as recurrent infections and atopic dermatitis (AD)-like skin lesions. AD is a chronic inflammatory skin disease with immunologic alterations (Th2-Th22 polarization) and characteristic skin barrier dysfunctions. Our aim was to investigate(More)
Recently, we reported elevated proportions of circulating follicular T helper cells and higher levels of interleukin- (IL-) 21 in primary Sjögren's syndrome (pSS). Interaction of invariant natural killer T (iNKT) cells with B cells and granzyme B (GrB) production may be also important in pSS. Thirty-two pSS patients and 24 healthy controls were enrolled in(More)
We describe here a novel c.137 + 5G > A intronic mutation in the SH2D1A gene of the signaling lymphocyte activation molecule (SLAM)-associated protein (SAP) in association with Epstein-Barr virus (EBV)-induced fatal infectious mononucleosis (FIM) in an 8-year-old male patient and his 3-year-old step brother. The mother and the maternal grandmother of the(More)
We tested the effect of various doses of bacterial lipopolysaccharide (LPS, endotoxin) on the expression of CD63 and the in vitro release of histamine by basophils stimulated with ragweed allergen in patients with or without ragweed and mite allergies. The peripheral blood of 11 patients with ragweed allergy, 10 patients with mite allergy and 14 control(More)
The changes in the number of CD8+ T lymphocytes were studied before (0 day) and then 30 days after the autologous hematopoietic stem cell transplantations (AHSCT) in 14 therapy refractory patients with autoimmune diseases. The years of survival and the clinical states were also evaluated. The number of CD8+ T cells was determined by an hematologic automat(More)
