BACKGROUND: Hypertensive leg ulcers (HLU) are a form of necrotic leg ulcer. Their physiopathology is not well known and in these patients, no venous or arterial insufficiency is detected. The primary objective of this study was to evaluate the association between HLU severity and the presence or absence of concomitant vitamin K antagonist (VKA) medication. We furthermore aimed to describe the epidemiology of this entity and the prevalence of thrombophilia factors in this population. PATIENTS AND METHODS: This was a retrospective study in 54 patients hospitalized in the dermatology department of Reims University Hospital between 01/01/2007 and 31/12/2013: 23 patients were included in the "without VKA" group, and 30 were included in the "with VKA" group...

Portal vein (PV) thrombosis (PVT) in the absence of liver disease or thrombophilia is rare. We report a 57-year-old male with a history of stage 3 chronic kidney disease who presented at the emergency department 18 months after abdominal surgery with progressive abdominal pain and distention. Computed tomography revealed PVT with multiple collaterals and moderate ascites. He had undergone partial gastrectomy and gastrojejunal anastomosis at an outside facility for gastrointestinal stromal tumors that caused an iatrogenic stenotic lesion in the PV...

BACKGROUND: Recurrent pregnancy loss (RPL) or recurrent spontaneous abortion is an obstetric complication that affects couples at reproductive age. Previous reports documented a clear relationship between parents with chromosomal abnormalities and both recurrent miscarriages and infertility. However, limited data is available from the Arabian Peninsula which is known by higher rates of consanguineous marriages. The main goal of this study was to determine the prevalence of chromosomal abnormalities and thrombophilic polymorphisms, and to correlate them with RPL and consanguinity in Saudi Arabia...

Congenital thrombophilia which is characterized by deficiencies in proteins such as antithrombin (AT), protein C (PC) and protein S (PS), is a major cause of venous thromboembolism (VTE). A total of 130 patients with VTE were evaluated for congenital thrombophilia based on the activity of AT, PC, or PS. Fifteen VTE patients with congenital AT deficiency (11.5 %), 16 with congenital PC deficiency (12.3 %) and eight with congenital PS deficiency (6.2 %) were diagnosed using DNA analysis. The frequency of congenital AT deficiency was significantly higher in subjects with pregnancy-related and idiopathic VTE than in those with VTE due to other causes, and congenital PC and PS deficiency were frequently associated with idiopathic VTE...

Thrombosis is a common complication in cancer patients. Although the major inherited risk factors for thrombophilia are different between Asians and Caucasians, the main acquired risk factors that are associated with the development of venous thromboembolism (VTE) in Asians appear to be similar to those for Caucasians. Malignancy is the most important acquired risk factor for VTE in Asians. Recent studies have shown that the incidence of VTE is significant in Asian patients with cancer, particularly those in an advanced stage...

In recent years, genetic analyses of congenital deficiencies of three anticoagulant proteins, antithrombin, protein C (PC) and protein S (PS), in East Asian patients with venous thromboembolism (VTE) have greatly increased. The PS-K196E mutation is often identified in the Japanese population with an allelic frequency of 0.86 %, and a total of approximately 10,000 Japanese are estimated to be homozygotes. The heterozygotes show PS anticoagulant activities ranging from 40 to 110 %, and 16 % lower mean anticoagulant activity than that in wild-type individuals...

In Dengue Hemorrhagic Fever (DHF), hemorrhagic manifestations are common but thrombotic events are uncommonly reported, despite the wide range of increased procoagulant activity during Dengue Fever illness. We report a case of a 55-year-old man of Asian Indian ethnicity who developed large vein thrombotic event -Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) in the acute phase of DHF. His condition was further complicated by associated thrombocytopenia. The etiological connections between dengue viral infection with thrombocytopenia, DVT/PE and abnormal thrombophilia profile as well as the treatment dilemmas posed in treating a patient of DF with hemorrhagic manifestations and associated DVT/PE, and the role of eltrombopag are discussed...

BACKGROUND: At present, the patient preparation for IVF needs to undergo a series of planned tests, including the genotyping of single nucleotide polymorphism (SNP) alleles of some genes. In former USSR countries, such investigation was not included in overwhelming majority of health insurance programs and paid by patient. In common, there are prerequisites to the study of more than 50 polymorphisms. An important faced task is to determine the optimal panel for SNP genotyping in terms of price/number of SNP...

Thrombophilia or hypercoagulable conditions can be thought of as either inherited or acquired. The inherited disorders include deficiencies of antithrombin, protein C, or protein S or the common disorders of factor V Leiden and prothrombin G20210A gene mutation. All these disorders are inherited as autosomal dominant and predispose individuals primarily to venous thrombosis. Acquired thrombophilic conditions are seen in individuals with cancer, phospholipid antibodies, and a whole host of other conditions that alter endothelial function, change blood levels of coagulant or anticoagulant proteins, activate platelets, or have other effects on coagulation proteins, platelet function, or the endothelium...

Idiopathic or unprovoked venous thromboembolism is an event occurring in the absence of any apparent provoking or triggering environmental risk factors, such as surgery, trauma, and immobilization. Areas covered: Unprovoked VTE can be associated with occult cancer, but only limited, and not extensive cancer screening, may be warranted, as the rate of occult cancer is low in such patients. Routine thrombophilia testing is not currently recommended as it does not influence the management of the disease. The duration of anticoagulation for unprovoked VTE after the first three months is still debated as the disease tends to recur regardless of treatment duration...

A 38 years old male patient presented to the emergency department with acute severe retrosternal chest pain and was found to have pulmonary thromboembolism. The patient developed new necrotic lung cavities each day due to the dissemination of emboli from the thrombus. The cause of thrombus was found to be protein C deficiency, which is an inherited thrombophilia. The interesting features in this case are multiple lung cavitations and high grade fever, which was attributed to pulmonary thromboembolism. The patient improved symptomatically with anticoagulants and antiplatelets...

BACKGROUND: Venous thromboembolism (VTE) is a common and potentially lethal disorder that manifests mainly as deep vein thrombosis (DVT) of the extremities or pulmonary embolism (PE) and occurs as a consequence of genetic and environmental risk factors. We aimed to assess the role of inherited thrombophilia as a causative or additive factor in the development of VTE. METHODS: The study included 310 patients (female: 154; mean age: 52.3 ± 16.9 years) with a first episode of VTE and 289 age- and sex-matched healthy controls...

BACKGROUND: Placenta-mediated pregnancy complications include pre-eclampsia, late pregnancy loss, placental abruption, and birth of a small-for-gestational-age (SGA) neonate. These complications are leading causes of maternal, fetal, and neonatal morbidity and mortality in high-income countries. Affected women are at high risk of recurrence in subsequent pregnancies; however, effective strategies to prevent recurrence are absent. Findings from our previous study-level meta-analysis suggested that low-molecular-weight heparin reduced the risk of recurrent placenta-mediated pregnancy complications...
