Low-molecular-weight heparin versus placebo for the prevention of venous thromboembolism in metastatic breast cancer or stage III/IV lung cancer.

In 2 double-blind studies, ambulatory patients with objectively proven, disseminated metastatic breast carcinoma (TOPIC-1) or stage III/IV non-small-cell lung carcinoma (TOPIC-2) were randomized to certoparin 3000 IU or placebo subcutaneously once daily, for 6 months. Primary efficacy outcome was objectively confirmed symptomatic or asymptomatic venous thromboembolism (VTE). Safety outcomes included bleeding (major and minor), and thrombocytopenia.

Antiphospholipid syndrome and pre-eclampsia.

Antiphospholipid syndrome (APS) is defined as an autoimmune disorder characterized by recurrent thrombosis or obstetrical morbidity. These features are linked to the presence in blood of autoantibodies against negatively charged phospholipids or phospholipid-binding proteins. Obstetric morbidity includes recurrent abortion (early and late) and severe pre-eclampsia (P-EC)/hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, and/or severe placental insufficiency.

CD3-CD56+CD16+ natural killer cells and improvement of pregnancy outcome in IVF/ICSI failure after additional IVIG-treatment.

Problem: The purpose of this retrospective, observational study was to investigate whether additional treatment with intravenous immunoglobulin (IVIG) increased the rate of successful pregnancies after repeated implantation failure (RIF). The retrospective data were compared with data of patients without IVIG-therapy from the meta-analysis of Clark et al.

Method Of Study: A total of 188 women with 226 treatment cycles between 2007 and 2009 were evaluated for IVIG therapy.

Blood rheology at term in normal pregnancy and in patients with adverse outcome events.

Plasma volume expansion of more than 1.5 l and sustainable activation of the hemostatic system that results in a steady rise of the fibrinogen/fibrin turnover are contemporary physiological events during normal pregnancy. In contrast, adverse outcome of pregnancy i.

Pregnancy outcome in women with antiphospholipid antibodies: report on a retrospective study.

Antiphospholipid syndrome (APS) represents a serious risk factor in pregnancy resulting in several complications, leading to fetal loss and hemostatic complications. In this dedicated report, we describe our experiences in the treatment of pregnancies in patients with APS. The retrospective data from 140 pregnant women were investigated, and the treatment results of 121 patients were recorded.

Mean maternal second-trimester hemoglobin concentration and outcome of pregnancy: a population-based study.

Both anemia and the lack of physiological maternal plasma volume expansion during the second trimester are associated with higher maternal morbidity and poor fetal outcome. Mean hemoglobin levels between the 14th and 30th gestational weeks were calculated in 4985 consecutive pregnant women and were correlated with outcome data of pregnancy. It was found that 9.

Hemostatic abnormalities in patients with severe preeclampsia.

Preeclampsia is the most common medical disorder of pregnancy. Early onset preeclampsia is defined as presentation of hypertension and proteinuria before 34 weeks of gestation. Alterations of endothelial cells and fibrin deposition in microvasculature lead to enhanced activation of the coagulation cascade and impaired fibrinolysis associated with multiple organ dysfunctions.

Antihypertensive therapy in patients with pre-eclampsia: A prospective randomised multicentre study comparing dihydralazine with urapidil.

Background: Drug treatment is imperative for pregnant women with pregnancy-induced hypertension (PIH) and pre-eclampsia. For more than 40 years, dihydralazine has been the drug of choice for this indication. Another particularly effective and better tolerable antihypertensive is urapidil.

Monitoring of rheologic variables during postoperative high-dose brachytherapy for uterine cancer.

Oxygenation of tumor tissue has recently been assed an important prerequisite for the effectiveness of radiotherapy in cervical cancer. Hyperviscosity is a common phenomenon in malignancy and a cause of reduced oxygen transport capacity that would favour tissue hypoxia. Hemorheological variables were serially tested preoperatively, during four cycles of fractionated adjuvant IR(192) HDR after loading radiation (HDR-AL) of the vaginal vault (weekly intervals), and 6 months postoperatively in patients with cervical (n=12) and endometrial cancer (n=26).

Impact of rheological variables in cancer.

Rheological alterations are commonly found in malignant disease and are most pronounced in advanced-stage cancer. Although most of these changes are caused by cancer-unspecific mechanisms, it has been shown that the extent of these changes in some cancer types is related with the stage of cancer, prognosis of disease, and the patient's risk for thrombosis. Monitoring of rheological variables during follow-up of patients has been useful in gynecologic cancer; a significant increase in the main determinants of blood viscosity was found when metastasis became clinically apparent.

Antiphospholipid syndrome in obstetrics.

Antiphospholipid syndrome (APLS) in pregnancy is characterized by the presence of autoantibodies in association with recurrent fetal loss and severe complications such as preeclampsia, fetal growth retardation, or placental insufficiency. The most clinically important serologic markers are lupus anticoagulant, anticardiolipin antibodies, and recently anti-beta-2-glycoprotein 1 antibodies. At present, standardization does not exist and a definitive association between specific clinical manifestation and antibody level is not yet known.

A whole blood flow cytometric determination of platelet activation by unfractionated and low molecular weight heparin in vitro.

The influence of unfractionated (Heparin-Natrium) and low-molecular heparin (Fragmin(R)) on platelet activation in whole blood was investigated by FACS analysis in vitro using antibodies against glycoprotein (gp) IIb/IIIa (CD 41), GMP 140 (CD 62P), gp 53 (CD 63) and fibrinogen. Samples were also labeled with anti-gp Ib (CD 42b). Neither unfractionated heparin (UFH) nor low molecular weight heparin (LMWH) led to significant (i.

ProC Global assay in the evaluation of women with history of severe preeclampsia or HELLP syndrome.

Preeclampsia/HELLP syndrome has been associated with a high incidence of defects in the protein C pathway and increased anticardiolipin-antibodies/lupus anticoagulants. It is also apparent that thrombophilia is responsible for other pregnancy complications, such as recurrent spontaneous abortion, fetal growth restriction, intrauterine fetal death, and abruptio placentae. ProC Global is a new global dotting assay designed to evaluate the abnormalities in the protein C anticoagulant pathway.

Prognostic role of plasmaviscosity in breast cancer.

Tumor growth leads to tissue hypoxia and tissue hypoxia, in turn, is a strong stimulus for expression of genes encoding factors that promote tumor growth. Likewise, hypoxia is a key condition within the vicious cycle of autogenous neoplastic dissemination. A marker of the presence of tissue hypoxia may be the presence of high blood viscosity, which is found in a number of neoplastic diseases including gynecological cancer.
