Increased risk for venous thrombosis in carriers of the prothrombin G→A20210 gene variant
1998
A mutation in the prothrombin gene (G--A20210) has been associated with higher plasma prothrombin levels and an increased tendency for venous thrombosis.To determine whether the prothrombin A20210 allele is independently associated with the occurrence of venous thrombosis.Case-control study.Two thrombosis centers in southern Italy.281 consecutive patients with venous thrombosis confirmed by objective tests and 850 controls.Medical history was collected on standardized questionnaires. The presence of prothrombin G--A2020 and factor V Leiden mutations was determined by polymerase chain reaction. The presence of anticoagulant factors and prothrombin activity was determined by tests of function…
Deep Venous Thrombosis: Leukocyte Rheology at Baseline and after in vitro Activation
2001
We evaluated leukocyte rheology, expressed as leukocyte filtration, polymorphonuclear (PMN) membrane fluidity and cytosolic Ca<sup>2+</sup> concentration in subjects with acute deep venous leg thrombosis (DVT). In 14 subjects with leg DVT we examined the leukocyte filtration [unfractionated, mononuclear cells (MN), PMNs], PMN membrane fluidity and PMN cytosolic Ca<sup>2+</sup> concentration. Subsequently, we evaluated the same PMN variables after in vitro chemotactic activation with 4-phorbol-12-myristate-13-acetate. At baseline, we observed a significant difference in the filtration of unfractionated and MNs and in PMN cytosolic Ca<sup>2+</sup> concentra…
Superficial venous thrombosis: Prevalence of common genetic risk factors and their role on spreading to deep veins
2008
Introduction. Superficial venous thrombosis (SVT) has been considered for a long time a limited clinical condition with a low importance, but this approach has changed in recent years, when several studies demonstrated spreading to deep veins occurring from 7.3 to 44%, with high prevalence of pulmonary embolism . Materials and Methods. To evaluate the prevalence of genetic risk factors for VTE in patients suffering from SVT on both normal and varicose vein, and to evaluate their role on spreading to deep veins, we studied 107 consecutive outpatients with symptomatic SVT. Ultrasound examination was performed, and the presence of FV Leiden, Prothrombin G20210A mutation, MTHFR C677T mutation w…
Superficial thrombophlebitis in varicose vein disease: the particular role of methylenetetrahydrofolate reductase.
2010
Background The purpose of this study was to compare the genetic background of superficial (SVT) and deep vein thrombosis (DVT). Methods Factor V (FV)-Leiden (G16891A)-, factor II(G20210A)-mutations, protein C- and S, as well as methylenetetrahydrofolate reductase (MTHFR) polymorphisms at C677T and A1298C, and serum homocysteine levels (hcy) were determined in 29 patients with SVT and 26 with DVT. Findings FV- and –II-mutations were less frequent in patients with SVT (2/3) compared with DVT (9/5), respectively ( P < 0.002 in case of FV). However, the frequency of the MTHFR C677T polymorphism was significantly higher in patients with SVT compared with DVT (CT 12 versus 10, and TT 7 versus …
Sulodexide versus calcium heparin in the medium-term treatment of deep vein thrombosis of the lower limbs.
1997
Thirty adult patients with distal, monolateral deep vein thrombosis of the lower limbs were randomly treated for sixty days either with subcutaneous Ca-Heparin or with Sulodexide, administered IM for ten days and orally for fifty days. The thrombus accretion above the knee, the venous pressures of the affected leg, the clinical sympto matology, and some laboratory coagulative tests were monitored throughout the admin istration period. Local tolerability of the two treatments was also evaluated.The two applied treatments evidenced a net antithrombotic activity, preventing thrombus accretion above the knee, improving with the same efficacy the venous pressures in the affected legs, and simila…
Prevention of deep vein thrombosis in neurosurgical patients: a prospective double-blind comparison of two prophylactic regimen.
1992
In a prospective, randomized, double-blind investigation of anticoagulant agents for prevention of deep vein thrombosis in patients undergoing operations at the lumbar-vertebral disc, 179 patients were randomly allocated to two groups. 87 patients received a fixed combination of low-molecular weight heparin 1,500 U-aPTT plus dihydroergotamine 0.5 mg (LMWH/DHE) once a day and additionally one injection of placebo per day, 92 patients received a fixed combination of sodium heparin 5,000 U plus dihydroergotamine 0.5 mg (HDHE) twice a day. Treatment was initiated two hours preoperatively in both groups and continued for at least seven days. Deep vein thrombosis (DVT), detected by the 125Iodine-…
Monitoring prothrombin fragment 1+2 during initiation of oral anticoagulant therapy after intracoronary stenting
1992
Patients with intracoronary stent implantation are treated with aggressive anticoagulant and antiplatelet therapy consisting of high-dose heparin, phenprocoumon, acetylsalicylic acid, dipyridamole, and the infusion of dextran to prevent a subacute thrombotic occlusion of the stented segment. In an effort to optimize this treatment by reducing both imminent bleeding complications and subacute thrombotic occlusion, the concentrations of prothrombin fragment 1 + 2 (F 1 + 2) were determined after intracoronary Palmaz-Schatz stent implantation in 19 consecutive patients. The F 1 + 2 concentrations after stent implantation and before the initiation of oral anticoagulant therapy (OAT) were 0.35 nm…
Cutaneous Lupus Erythematosus
2008
Lupus erythematosus (LE) is an inflammatory autoimmune disease, characterized by a heterogeneous clinical presentation. The skin lesions are one of the most frequent symptoms of the disease and present with a broad spectrum of LE-nonspecific and LE-specific cutaneous manifestations. Therefore, the development of a classification for skin lesions in the disease has proven difficult. For example, the LE-nonspecific cutaneous manifestations include livedo racemosa, thrombophlebitis, and leukocytoclastic vasculitis and can be associated with high disease activity and systemic organ involvement. The LE-specific cutaneous manifestations encompass the subtypes of cutaneous lupus erythematosus (CLE…
IL PIANO DEL CONSUMATORE SOVRAINDEBITATO: TENTATIVI DI RIFORMA E PROSPETTIVA EUROPEA
2016
Social Inclusion and responsible lending seem to became the main policy roots along which a new regulatory framework for households credit and particularly for consumer credit is being shaped at Europeanlevel;throughtheinterplaybetweenthetwo,non-economic goals such as fighting poverty spread and promoting social cohesion can be combined with properly economic ones, such as the systemic risks prevention arising from weak credit access filter mechanism. Proofs of that come from political documents as well as from proper sources of law: suffice to mention the 2016 Opinion of the European Economic and Social Committee on “Fighting poverty”, on the one hand, and the Directive 2014/17 EU on credit a…
Les climats régionaux : observation et modélisation : actes du colloque
2012
6 pages; International audience; L'objectif de cette étude est de caractériser les variations spatio-temporelles des flux sédimentaires de la basse vallée du Mono-Couffo (bassin versant partagé par le Bénin et le Togo), à partir des données de matières en suspension (MES), de débits solides (TSS), de pluie, du débit et des données concernant l'occupation du sol pour mieux apprécier l'impact de la dégradation du couvert végétal sur le flux des sédiments terrigènes. Il ressort de l'analyse une diminution de plus de 60 % des formations naturelles entre les années 1956 et 2000, contribuant à une augmentation des apports spécifiques dans la basse vallée. Une charge solide considérable en matière…
