Hormonal replacement therapy and venous thrombosis

W Ammouri, Z Mezalek Tazi, H Harmouche, M Maamar, M Adnaoui
BACKGROUND: Hyperhomocysteinemia has been suspected of favoring thrombosis. Several case-control studies and even a meta-analysis have confirmed a link between venous thrombosis and hyperhomocysteinemia. Homocysteine is due to genetic and acquired factors (poor diet in folate and vitamin B12, older age, renal impairment, thyroid diseases, and malignancies) induced by the intake and the concentrations of vitamin B9 or B12 in the majority of cases. CASES PRESENTATION: We report the cases of four Moroccan patients who presented with acute vein thrombosis of different sites: a 34-year-old man, a 60-year-old man, a 58-year-old man, and a 47-year-old woman...

Postmenopausal hormone replacement therapy (HRT) with estrogen plus progestogens is the first line therapy to treat menopausal symptoms. The progestogen is added to estrogen to reduce or eliminate the excess risk of endometrial cancer due to the unopposed effect of estrogen. Whereas progestin clearly opposes the proliferative and deleterious long-term actions of estrogen on the endometrium, the interference of progestin on the other estrogen action remains unclear. We previously reported that chronic subcutaneous 17α-estradiol (E2) in mice decreases platelet responsiveness, prolongs the tail-bleeding time and protects against acute thromboembolism...

Antiphospholipid syndrome (APS) is an autoimmune systemic disease characterized by vascular thrombosis (arterial or venous) and/or pregnancy complications associated with the occurrence of autoantibodies, specifically lupus anticoagulant, anticardiolipin antibodies, and/or anti-β2 glycoprotein-I antibodies confirmed at least twice over a 12 week period according to the 2006 Sydney criteria. Antiphospholipid antibodies are encountered  in the general population with a reported prevalence of 1% to 5%  However, APS is far more infrequent with a prevalence of 40-50/100,000 persons and an incidence of about 5 new patients/100,000 persons...

Deep venous thrombosis (DVT) has been reported extensively following ovarian hyperstimulation syndrome during in-vitro fertilization (IVF). Pregnancy per se increases the risk of DVT due to a hypercoagulable state. The long-term use of hormone replacement therapy (HRT) is another critical factor associated with DVT in women. However, an association between the short-term use of HRT in oocyte donation (OD) cycles and DVT has not yet been reported. We present a case of 43-year-old woman who developed DVT after IVF-OD...

Our hypothesis was that testosterone therapy (TT) interacts with previously undiagnosed thrombophilia-hypofibrinolysis, leading to hospitalization for deep venous thrombosis (DVT)-pulmonary emboli (PE). We determined the prevalence of DVT-PE associated with TT 147 men hospitalized in the last 12 months for DVT-PE. Of the 147 men, 2 (1.4%) had TT before and at the time of their DVT-PE. Neither had risk factors for thrombosis. Neither smoked. Case #1 (intramuscular T 50mg/week) had 2 PE, 6 and 24 months after starting TT...

OBJECTIVE: With increasing free thyroxine levels, a gradually rising risk of venous thromboembolism has been described in case-control studies. However, reports on the influence of thyroid hormones on haemostasis, while suggesting a hypercoagulable state in thyrotoxicosis, have often been inconclusive. This study evaluates multiple markers of haemostasis and fibrinolysis in a paired design, making it more sensitive to changes in thyroid hormone levels. DESIGN: We analysed multiple variables in patients who shifted from severe hypothyroidism to mild hyperthyroidism during thyroid cancer treatment...

BACKGROUND: Sickle cell trait may increase risk of venous thromboembolism, but this is not fully established. OBJECTIVES: We sought to determine the association of sickle cell trait with deep vein thrombosis and pulmonary embolism. METHODS: Middle-aged African Americans participating in a prospective, population-based cohort investigation, the Atherosclerosis Risk in Communities Study, were followed from 1987 through 2011 for incident hospitalized pulmonary embolism (n = 111) or isolated deep vein thrombosis (n = 138), verified by physician review of medical records...

To investigate the characteristics and clinical course of cerebral vein thrombosis (CVT) in patients with myeloproliferative neoplasms (MPN) we compared 48 patients with MPN and CVT (group MPN-CVT) to 87 with MPN and other venous thrombosis (group MPN-VT) and 178 with MPN and no thrombosis (group MPN-NoT) matched by sex, age at diagnosis of MPN (±5 years) and type of MPN. The study population was identified among 5,500 patients with MPN, from January 1982 to June 2013. Thrombophilia abnormalities were significantly more prevalent in the MPN-CVT and MPN-VT than in MPN-NoT group (P = 0...

BACKGROUND: Some evidence suggests that an inadequate vitamin D level may increase the risk for atherosclerotic cardiovascular disease. Whether a low vitamin D level plays a role in venous thromboembolism (VTE), that is, venous thrombosis and pulmonary embolism, is largely unexplored. OBJECTIVES: We tested prospectively, in the Atherosclerosis Risk in Communities (ARIC) cohort, whether the serum level of 25-hydroxyvitamin D (25[OH]D) is inversely associated with VTE incidence, and whether it partly explains the African American excess of VTE in the ARIC Study...

With an increasing world population of postmenopausal women, providers of health care need to focus on improving the quality of life as well as the longevity of women. This review emphasizes the importance of health care for postmenopausal women, particularly the role of menopausal hormonal therapy (MHT), from the perspective of where we have been, where we are now, and where we can expect to be in the future. Use of MHT increased dramatically in the 1980s and then fell very abruptly in the early 2000s with the publications of various randomized hormonal trials, including the Women's Health Initiative (WHI)...

Venous thromboembolism (VTE) is a major harmful effect of hormone therapy (HT) among postmenopausal women. A large variety of HT can be used with significant differences in adverse effects. There is evidence that the VTE risk among HT users depends on the route of estrogen administration. Oral but not transdermal estrogens dose-dependently increase the VTE risk. This difference is supported by biological data. Whereas oral estrogens increase thrombin generation and induce resistance to activated protein C, transdermal estrogens have minimal effect on hemostasis...

Menopausal hormone therapy (HT) has complex biologic effects but continues to have an important clinical role in the management of vasomotor and other menopausal symptoms. The rational use of menopausal HT requires balancing the potential benefits and risks of treatment. Findings from the Women's Health Initiative (WHI) and other randomized clinical trials have helped to clarify the benefits and risks of HT and have provided insights to improve decision making. Several clinical characteristics have utility in identifying women for whom benefits of HT are likely to outweigh the risks...

BACKGROUND: Postmenopausal hormone therapy (HT) increases the risk of venous thrombosis and ischemic stroke. OBJECTIVES: We postulated that HT might increase the risk of ischemic stroke by promoting venous clots that travel to the brain through a right to left shunt (RLS). METHODS: A total of 2,389 records were studied. After eliminating the premenopausal patients, and those with TIAs and non-ischemic strokes, the medical records of 1846 postmenopausal women hospitalized at four institutions for ischemic stroke were reviewed to identify those who had undergone an adequate study to assess for RLS...

BACKGROUND: The risk of venous thrombosis (VT) associated with oral hormone therapy (HT) may differ by type of estrogen compound. OBJECTIVE: To compare the thrombotic profile of women using oral conjugated equine estrogens (CEE) with that of women using oral estradiol (E2). METHODS: In postmenopausal, female, health maintenance organization (HMO) members with no history of VT, we measured thrombin generation, levels of factor VII activity, antithrombin activity and total protein S antigen...

BACKGROUND: Inflammatory bowel disease (IBD) is a well-known risk factor for venous thromboembolism (VTE). Existing guidelines for thromboprophylaxis in hospitalized patients do not extend to other clinical scenarios that may also be associated with VTE risk. Our aim was to estimate the fraction of VTE events in patients with IBD that could be prevented. METHODS: A retrospective analysis assessed all patients with IBD diagnosed with VTE at a single academic medical center from 2002 to 2012...

In postmenopausal women, estrogen (E2) deficiencies are frequently associated with higher risk of intracranial hemorrhage, increased incidence of stroke, cerebral aneurysm, and decline in cognitive abilities. In younger postpartum women and those using oral contraceptives, perturbations in E2 are associated with higher risk of cerebral venous thrombosis. A number of serious intracranial pathologic conditions linked to E2 deficiencies, such as dural sinus thrombosis, dural fistulae, non-parenchymal intracranial hemorrhages, migraines, and spontaneous cerebrospinal fluid leaks, involve the vessels not of the brain itself, but of the outer fibrous membrane of the brain, the dura mater (DM)...

Hypoestrogenism is the primary etiologic factor for osteoporosis and related fractures, as well as for a number of clinical symptoms that can reduce the quality of life in postmenopausal women. Alternative to classical hormone replacement therapy (HRT) are needed for women that cannot or don't want to be treated with hormones. Selective estrogen receptor modulators (SERMs) are compounds that lack the steroid structure of estrogens, but interact with estrogen receptors (ERs) as agonists or antagonists depending on the target tissue...

BACKGROUND: Use of oral contraceptives with estrogen and hormone replacement therapy with estrogen or testosterone are associated with increased risk of venous thromboembolism (VTE). However, whether endogenous estradiol and testosterone concentrations are also associated with risk of VTE is unknown. OBJECTIVE: We tested the hypothesis that elevated endogenous total estradiol and total testosterone concentrations are associated with increased risk of VTE in the general population...
