Purpose: The aim of this study was to compare effects of the transdermal contraceptive patch, a desogestrel/ethinyl estradiol (EE)-containing, monophasic combination oral contraceptive (COC) and a levonorgestrel/EE-containing, triphasic COC on hemostasis variables. Study Design: This was a randomized, open-label study of 104 young women who...

Objective: We evaluated the effects of a new combined hormonal contraceptive vaginal ring (CVR) delivering the nonandrogenic progestin Nestorone® (NES) and ethinyl estradiol (EE) on several key estrogen-sensitive hepatic proteins that may be markers for the risk of arterial or venous disease events and on blood pressure (BP). Because the...

Objective: This study aimed to compare the effects on hemostasis variables of a contraceptive vaginal ring with those of an oral contraceptive. Study design: Twenty-three and 22 healthy premenopausal women were randomized to the contraceptive vaginal ring (150 μg Nestorone and 15 μg ethinyl estradiol) or Stediril 30 during 3 cycles. Analysis of...

Purpose: In this open-label, randomized study, we assessed the effects on hemostasis of two combined oral contraceptives containing drospirenone (DRSP) as progestogen component. Methods: Three milligrams of DRSP, a progestogen with antimineralocorticoid activity, was combined with either 30 or 20 μg ethinyl estradiol (EE) (DRSP/30EE; DRSP/20EE)...

Combined association and linkage analysis is a powerful tool for pinpointing functional quantitative traits (QTLs) responsible for regions of significant linkage identified in genome-wide scans. We applied this technique to apoE plasma levels and the APOEε2/ε3/ε4 polymorphism in two Dutch twin cohorts of different age ranges. Across chromosome...

The genetic basis of cardiovascular disease (CVD) with its complex etiology is still largely elusive. Plasma levels of lipids and apolipoproteins are among the major quantitative risk factors for CVD and are well-established intermediate traits that may be more accessible to genetic dissection than clinical CVD end points. Chromosome 19 harbors...

Plasma levels of lipoprotein(a) - Lp(a) - are associated with cardiovascular risk (Danesh et al., 2000) and were long believed to be influenced by the LPA locus on chromosome 6q27 only. However, a recent report of Broeckel et al. (2002) suggested the presence of a second quantitative trait locus on chromosome 1 influencing Lp(a) levels. Using a...

Background: Flow mediated dilatation (FMD) of the brachial artery and soluble intercellular adhesion molecule 1 (sICAM-1) are measures of distinct functions of the endothelium, reflecting nitric oxide (NO)-mediated and pro-inflammatory status, respectively. The comparative value of the two measures in relation to cardiovascular risk is unknown....

The factor V Leiden mutation (conferring resistance to activated protein C) has been implicated in the risk of arterial thrombosis and is a well-established risk factor for venous thrombosis especially in the elderly. We studied whether the disease association of the factor V mutation is reflected in an increased all-cause and cause-specific...

Plasma levels of histidine-rich glycoprotein (HRG) were investigated in three groups of women receiving a different dose of estrogens. First, the effect of low-dose estrogen was studied in a group of 83 postmenopausal women who were treated with 0.625 mg conjugated estrogens (CE). No significant change from baseline levels was found at the end...

Two hundred and three patients with venous thrombophilia were investigated in order to find out whether an elevated plasma concentration of plasminogen activator inhibitor (PAI) could be a cause of their tendency to thrombosis. The patients were studied in an asymptomatic period about 3 months after their last thromboembolic episode. PAI...

??2-Antiplasmin (??2-AP) is a major fibrinolysis inhibitor, whose complete, congenital absence has been found to be associated with a distinct hemorrhagic diathesis. We studied a 15-yr-old male with a hemorrhagic diathesis after trauma from early childhood on. This bleeding tendency was associated with a minimal ??2-AP level recorded...

This study concerns a case of congenital homozygous deficiency in ??2-antiplasmin associated with a severe hemorrhagic diathesis. Heterozygous family members also show a mild bleeding tendency. The propositus is a 17-yr-old male born of white parents and showing a severe hemorrhagic diathesis characterized by spontaneous bleeding in the joints...
