Hereditary hyperferritinaemia-cataract syndrome (HHCS) is an autosomal dominant disease caused by mutations in the iron responsive element (IRE) of the l-ferritin gene. Despite the elucidation of the genetic basis, the overall clinical spectrum of HHCS has been less well studied as, to date, only individual case reports have been described. Therefore, we(More)
5, 10-Methylenetetrahydrofolate reductase (MTHFR) is a crucial enzyme in homocysteine/methionine metabolism. The most-studied C677T polymorphism in the MTHFR gene results in a thermolabile variant with reduced activity, and is associated with increased levels of total plasma homocysteine, a risk factor for coronary artery disease. A new mutation in the(More)
Human parvovirus B19 infection is responsible for a wide range of human diseases ranging from mild erythema infectiosum in immunocompetent children to fetal loss in primary infected pregnant women and aplastic anemia or lethal cytopenias in adult immunocompromised patients. Since persistent viral infection is responsible for an autoimmune response and(More)
Celiac disease (CD) is an autoimmune disorder of the small intestine triggered by environmental factors in genetically predisposed individuals. A strong association between type 1 diabetes (T1DM) and CD has been reported. We have previously shown that rotavirus infection may be involved in the pathogenesis of CD through a mechanism of molecular mimicry.(More)
The 677 C-->T polymorphism in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene interacts with folate status in determining elevated total plasma levels of homocysteine, a risk factor for coronary atherosclerotic disease (CAD). The present study had the following goals: 1) to define the 677 C-->T genotype-specific threshold values of both plasma and(More)
BACKGROUND Iron may promote coronary atherosclerotic disease (CAD) by increasing lipid peroxidation. Studies on biochemical or genetic markers of body iron stores as risk factors for CAD have yielded conflicting results. METHODS We studied 849 individuals with a clear-cut definition of the CAD phenotype, i.e., with (CAD; n = 546) or without (CAD-free; n =(More)
Systemic sclerosis (SSc) is characterized by vascular dysfunction that may lead to pulmonary artery hypertension (PAH). The N-terminal pro-B type natriuretic peptide (NT-proNBP), a marker of cardiac failure, is a diagnostic marker of early PAH in patients with SSc without heart failure. Our aim was to determine whether NT-proBNP levels may be a useful tool(More)
The objectives of the study are to evaluate DNase I serum levels and their correlation with soluble Fas (sFas) and soluble Fas ligand (sFasL) and with cell surface Fas expression in patients with systemic lupus erythematosus (SLE), thus contributing to the dysregulated apoptosis typical of the disease. The methods include the following: Serum DNase I levels(More)
Vasculopathy, immunological abnormalities, and excessive tissue fibrosis are key elements in the pathogenesis of progressive systemic sclerosis (SSc). Extracorporeal shock waves (ESW) have anti-inflammatory and regenerative effects on different tissues. We hypothesized that ESW can reduce endothelial cell damage and skin fibrosis in patients with SSc. We(More)
Sjögren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration and tissue damage mainly confined to the salivary and lacrimal glands, resulting in dryness of mouth and eyes. Since different epithelial cells of exocrine and non-exocrine tissues are primarily affected, an autoimmune reaction against antigens commonly expressed in(More)
