APOE and longevity: study of a population of Sardinian Centenarians
2011
Apolipoprotein E is a major determinant in lipoprotein metabolism and cardiovascular disease, it has emerged as an important molecule in several biological processes including Alzheimer's disease and cognitive function. ApoE is a polymorphic protein (ε2, ε3, ε4) with three proteic isoforms, ApoE2, ApoE3, ApoE4 (1). The aim of the study was to verify the frequencies of allelic variants a population of healthy elderly people. ApoE polymorphisms were determined by Real Time-PCR. The genotype frequencies of ApoE in our group of 71 centenarians (mean age 100.9 ±1.3) were: ε2/ε3 (12.67%); ε3/ε4 (5.63%). In the control group, consisting of 97 individuals (mean age 92.98 ±2.53), the genotype freque…
Vitamin K deficiency bleeding leading to a diagnosis of Crohn’s Disease
2014
We report the case of a 45 year old man who came to Emergency Room of Polyclinic for sudden onset of localized ecchymosis and widespread hematomas. He was subjected to blood count and first level investigations to assess coagulation. Based on the results, second level investigations were performed. Endoscopy of the gastrointestinal tract with histological examination revealed a diagnosis of Crohn's disease. Vitamin K deficiency causes the formation of vitamin K-dependent clotting factors that cannot perform their pro-coagulant action. Consequently, patients present with hemorrhagic manifestations. Clinical and laboratory features observed in this patient show that the deficiency of vitamin …

Polimorfismo I/D del gene per l'enzima di conversione dell'angiotensina (ACE): gene della longevità o fattore di rischio nella patologia ipertensiva?
2013
In recent decades, the increase in life expectancy stimulated the study of aging processes and the search for candidate genes involved in longevity. The angiotensin converting enzyme (ACE), present in all endothelial cells, plays an essential role in maintaining the homeostasis of blood flow by regulating the production of the vasoconstrictor angiotensin II and inactivating the bradykinin. Some studies reported a possible association between the polymorphism I/D of ACE gene and either hypertension and longevity. The present study was aimed to confirm these data. We studied two large cohorts of nonagenarians and centenarians. One was from Sardinia (200 subjects, 88 males, mean age: 96 years)…

Prothrombotic gene variants as risk factors of acute myocardial infarction in young women
2012
Abstract Background Acute myocardial infarction (AMI) in young women represent an extreme phenotype associated with a higher mortality compared with similarly aged men. Prothrombotic gene variants could play a role as risk factors for AMI at young age. Methods We studied Factor V Leiden, FII G20210A, MTHFR C677T and beta-fibrinogen -455G>A variants by real-time PCR in 955 young AMI (362 females) and in 698 AMI (245 females) patients. The data were compared to those obtained in 909 unrelated subjects (458 females) from the general population of the same geographical area (southern Italy). Results In young AMI females, the allelic frequency of either FV Leiden and of FII G20210A was signif…
Methylenetetrahydrofolate reductase homozygosis and low-density lipoproteins in patients with genotype 1 chronic hepatitis C
2011
Summary. Methylenetetrahydrofolate reductase status, homocysteine and lipoproteins levels have been associated with severity of disease and both rapid and sustained virological response (SVR) in patients with genotype 1 chronic hepatitis C (CHC). We aimed to assess the association of homocysteine and MTHFR status with serum cholesterol levels and their potential links to both histological findings and virological response, in patients with genotype 1 hepatitis C virus (HCV). A total of 119 consecutive patients were evaluated by biopsy and metabolic measurements. A total of 103 healthy blood donors were used as controls. Serum homocysteine and MTHFR C677T mutation were also evaluated. All p…

Fetuin-A serum levels are not correlated to kidney function in long-lived subjects
2012
Objectives: Serum Fetuin A has been identified as an inhibitor of ectopic calcification. It is reduced in subjects with chronic kidney disease (CKD) and it has been proposed as a potential link between CKD and the higher prevalence of arterial calcification observed in these patients. During ageing both the stiffening of arterial wall due to calcification and a decline in kidney function are frequent. The aim of the study is to investigate if Fetuin A serum levels are associated with ageing and with AHSG T256S polymorphism. Moreover, we aim at investigate whether serum Fetuin A is correlated to kidney function in this setting of senescence. Design and Methods: 256 health long-lived subjects…
Polimorfismo del gene ACE:gene della longevità o fattore di rischio nella patologia ipertensiva
2012
Negli ultimi decenni l’allungamento della vita media ha stimolato un particolare interesse nello studio dei processi dell’invecchiamento e nella ricerca di possibili geni coinvolti nella longevità. In particolare i centenari dimostrano di avere una prevalenza minore di malattie cardiovascolari e dei fattori di rischio ad essa correlati. L’enzima di conversione dell’angiotensina (ACE), presente in tutte le cellule endoteliali, gioca un ruolo essenziale nel mantenimento dell’omeostasi del flusso vascolare, regolando sia la produzione del vasocostrittore angiotensina II sia inattivando la bradichinina. In particolare alcuni studi hanno riportato una possibile correlazione tra il polimorfismo I…

2010
Abstract Introduction It is very suggestive that diabetic foot is characterized by a pronounced inflammatory reaction and the pathogenic significance of this inflammation has received little attention. On this basis the aim of our study was to evaluate plasma levels of adiponectin, resistin and IL-6 in subjects with diabetic foot in comparison with subjects without foot complications. Materials and methods We recruited 34 subjects with type 2 diabetes mellitus and foot ulceration hospitalized for every condition related to diabetic disease, but not for new vascular events (group A). As controls we recruited 37 patients with type 2 diabetes mellitus without foot ulceration (group B) hospital…

Fetun-A and end stage renal disease: correlations with haemodialytic single session and genotype
2011
Several studies showed that Fetuin-a is an extracellular calcium-regulatory protein acting as a potent inhibitor of calcium-phosphate precipitation, involved also in bone metabolism because of its high affinity for hydroxyapatite. The aim of this study is to evaluate the serum Fetuin-A levels in patients with chronic renal failure before and after a single session of dialysis and to investigate the correlation between protein serum concentrations and T256S genotype. Our results show that serum Fetuin- A levels decrease 4 hours after haemodialysis treatment and a significant correlation between 256SS homozygote and serum protein levels. Ectopic calcification and particularly intravascular ca…

Fetuin-A in elderly: effect of genotype on serum levels
2011
Fetuin-A is a circulating inhibitor of ectopic calcification in vivo; it is decreased in patients with chronic kidney disease and correlates with glomerular filtration rate in patients with coronary artery disease. However, serum levels of Fetuin-A has not been described in elderly. Aim of the study was to evaluate Fetuin-A serum levels together with AHSG T256S genotype in a population of healthy elderly. Serum fetuin-A levels were determined by ELISA. T256S polymorphism of AHSG gene was determined by PCR-RFLP. Serum Fetuin-A was 0,38 ± 0,13 g/l in the group composed by 206 healthy centenarians. Moreover, subjects with at least one S allele had lower Fetuin-A levels (P<001). Interestingly, …

MTHFR C677T allelic variant is not associated to plasma and cerebrospinal fluid homocysteine in amyotrophic lateral sclerosis
2014
Amiotrophic lateral sclerosis (ALS) is a neurological disorder with a multifactorial etiopathogenesis including excitotoxicity, intracellular calcium increase and mitochondrial damage together with oxidative stress and apoptosis. Overall, the relationship between homocysteine (Hcy), motoneuron death and ALS appears to be complex and still under investigation. It has been already shown that Hcy is elevated in plasma and cerebrospinal fluid (CSF) of ALS patients, although mechanisms of hyperhomocysteinemia have not been elucidated yet. MTHFR C677T variant is the most common genetic determinant of increased homocysteinemia, but no studies regarding the effect of this polymorphism in ALS patien…
