Trombotic

Atypical uremic haemolytic syndrome is a variant of thrombotic micro-andiopathy characterized by non-autoimmune hemolytic anemia, thrombocytopenia and acute renal failure as a result of excessive activation of the complement. Up to 60% of patients have mutations in the genes that encode the complement system. A disensing factor is required for its manifestation, including gestation. It is an entity with a high morbidity, which can decrease drastically if an early diagnosis is made and appropriate treatment is initiated...

Nutcracker syndrome refers to the complex of clinical symptoms caused by the compression of the left renal vein (LRV) between the abdominal aorta and the superior mesenteric artery, leading to stenosis of the aortomesenteric portion of the LRV and dilatation of the distal portion. Hematuria, proteinuria, flank pain, varicocele and pelvic congestion may occur, occurring more frequently in young adults. Conservative management, might be the option whenever it is possible. When surgical treatment is required, classically open surgery have been performed, with major surgeries as LRV transposition or bypass techniques...

Plasmapheresis also known as a therapeutic plasma exchange (TPE) is a procedure of plasma removal with it's ineligible plasma's component. Usually it is a supportive measure used simultaneously with the treatment, but in a few diseases, e.g. in trombotictrombocytopenic purpura (TTP), it is a first-choice treatment. During the plasmapheresis plasma is mostly replaced by 20% solution of albumin or combination of 20% solution of albumin and 0.9% solution of NaCl, however in some diseases fresh frozen plasma (FFP) is used...

The review contains different aspects indicating the participation of cytokines in aging-associated diseases. Authors reveal the role of short peptides in molecular mechanisms of homeostatic regulation in immune, cardiovascular, haemostatic systems which is based on the literature data and own experimental data. It is established that short peptides realize their geroprotective effect by changing gene expression of immune and proinflammatory cytokines and g-interferon.

The lung is most common site for metastatic disease via hematogenous route. Tumor emboli of the vessels of the lung induces fibrocellular and fibromuscular intimal proliferation. These histopathological changes may cause pulmonary tumor trombotic microangiopaty. Few cases are diagnosed antemortem. We report a 60 year old woman with by metastatic epithelioid angiosarcoma involving the lung. Tumor cells were positive for VEGF and topoisomerase II. VEGF may be involved in the pathogenesis pulmonary tumor trombotic microangioapy and topoisomerase II positivity showed sensitivity against catalytic topoisomerase II inhibitors...

COX inhibitors which selectively inhibits the inducible COX-2 is an oenzyme that causes inflammation. They are clinically effective anti-inflammatory agents with less gastrointestinal and renal toxicity. However, they lack anti-thrombotic activity and hence lead to increased incidences of adverse cardiovascular trombotic events such as myocardial infarction. Therefore, there is still a need to develop better therapeutic effect and tolerability COX-2 inhibitor. The majority of COX-2 inhibitors are diaryl heterocycles...

Abnormal hemostasis tests and bleeding are often associated in liver cirrhosis. In these patients the balance between hypo- and hypercoagulation status is more fragile than in healthy people. In the hemostatic abnormalities associated with chronic liver disease are two main chategory factors: favoring hemorrage and favoring thrombosis. The main factors that favoring hemorrage are: low platelet count, impaired platelet function, decreased levels coagulation factors (II, V, VII, IX, X, XI), quantitative and qualitative abnormalities of fibrinogen, vitamin K defiency, low levels of trombin activable fibrinolisis inhibitor, activat plasminogenic tisular...

AIM: The aim of this pilot study was to assess the venous hemodynamic changes after deep venous thrombosis (DVT) using air-plethysmography (APG) and to study the rate and magnitude of these changes in relation to those associated with the post-trombotic syndrome. METHODS: Twenty limbs of 19 patients with acute iliofemoral thrombosis have been followed up with APG and Duplex scanning for 24 months. Patients were treated with anticoagulation and elastic stockings...

The antiphospholipid syndrome (APhS) is autoimmune non-inflammatory trombotic vasculopathy, associated with damage of vessels of any caliber and localization that determines the diversity of clinical manifestations of this syndrome. One of possible localizations of thrombosis in AphS is pseudoinfective endocarditis (PsIE). We have performed analysis of clinical and laboratory features of APhS, associated with PsIE. 28 APhS patients with PsIE, average age--44+/-13 years, were included in the study. Among them 21 patients had primary form of APhS, 7 cases had secondary form of APhS...

Budd-Chiari syndrome is a rare disease, caused by obstruction of the hepatic venous outflow at the level of either the large hepatic veins or (and) the subdiaphragm segment of the inferior vena cava. The hematological disorders (myeloproliferative disorders, factor V Leiden deficiency), tumor and chronic inflammatory diseases are the most frequent causes of BCS in Europe and North America. Two cases of BCS, recognized in 24 and 43 years old females with subacute and chronic forms of the disease are presented in this article...

Among 269 biopsies performed in our institution in 2006, 24 biopsies were C4d positive. There were seven cases of early AMR (< 6 months post-transplant) and 17 cases of late AMR. Cellular rejection was found in 12 biopsies (50%) and classified as type I tubulointerstitial (six biopsies: five Banff IA and one Banff IB) and type II vascular (six biopsies: Banff IIA); in five biopsies (21%), borderline rejection was diagnosed. Changes consistent with chronic rejection were found in six biopsies (25% of all and 35% of biopsies in the late post-transplant period)...

Recurrent pregnancy loss is secondary to multiple illnesses. An important cause sometimes undiagnosed is the antiphospholipid syndrome, an autoimmune disease with various clinical alterations (miscarriage, hypertensive disorders, preterm delivery, vascular thrombosis, intrauterine retard growth, death intrauterine, abruption placentae). There are major and minor clinical criteria and precise indications that guide the physician to its recognition. Antibodies related with the syndrome are anticardiolipin and lupic anticoagulant, but other phospholipids seems to be implicated on this pathology and its participation on trombotic events is even unknown...

OBJECTIVES: to detect the prevalence of hyperhcy in SLE patients with and without antiphospholipid syndrom; to compare the Hcy levels between those patients and healthy controls and to determine the correlation between hyperhcy and antiphospholipid antibodies. PATIENTS AND METHODS: we studied 44 SLE patients: 17 had antiphospholipid syndrom and 27 didn't have it, and we compared them to 24 healthy controls. All of them where checked clinically and with laboratory tests like anticardiolypin antibodies, lupus anticoagulant and Hcy...

INTRODUCTION: Etiology of thrombosis in malignant diseases is multifactorial, and mechanisms that lead to thrombosis include release of the procoagulants from tumor cells (PC), factor related to bed rest, infections, as well as oncological therapy --chemotherapy, hormones, radiotherapy and surgical treatment. Thrombocytosis has frequently been found to be associated with various malignancies. CASE REPORT: 53 years old female patient hospitalised because of hypopharingeal cancer with metastasis in the left neck...

BACKGROUND: The trombofilia states are a special tendency to vein thrombosis that are habitually presented in young people and often they are recurrent. Their more transcendent consequences are the Lung Tromboembolismo and the Syndrome Post-trombótico. OBJECTIVES: Keeping in mind the pathologies of the clotting that can produce trombofilia states in young patients, the prevalence of these processes was evaluated in patient with post-trombotic severe syndrome...
