BACKGROUND: The frequency of knee arthroscopy procedures is increasing in pediatric and adolescent patients. In general, complications after these procedures in adolescents are uncommon. The purposes of this study are to report the incidence of venous thromboembolism (VTE) in adolescent patients after knee arthroscopy procedures, as well identify risk factors in this patient population. METHODS: Medical records were reviewed in all pediatric and adolescent patients (≤19 y) who underwent an arthroscopic knee procedure from 2010 to 2014 and were diagnosed with a symptomatic VTE in the postoperative period...

Traditional anticoagulant agents such as unfractionated heparin (UFH), low molecular weight heparins (LMWHs), fondaparinux, danaparoid and bivalirudine are used in the prevention and treatment of thromboembolic diseases. However, these agents have limitations: their constraining parenteral route of administration and the need for regular coagulation monitoring for HNF. The LMWHs, with their more predictable anticoagulant response, don't require a systematic monitoring. The usefulness of LMWHs monitoring in several clinical situations such as pregnancy, obesity and renal insufficiency is a matter of debate...

The rapid global uptake of noninvasive prenatal testing for Down syndrome based on maternal plasma cell-free DNA has provided new data on the interrelationship between cell-free DNA and maternal health. Specific maternal conditions that can affect the performance of noninvasive prenatal testing include obesity, active autoimmune disease and low molecular weight heparin treatment. There is also a growing appreciation of the implications of discordant noninvasive prenatal testing results for maternal health, including unexpected diagnoses of maternal chromosomal conditions, or rarely, occult cancer...

The American College of Cardiology Foundation /American Heart Association guidelines recommend a weight-based dose of unfractionated heparin (UFH) for primary percutaneous coronary intervention (PCI). However, it is convention to administer a fixed-bolus dose of 5,000 units of UFH. It is unclear if 5,000 units are sufficient to achieve a therapeutic first activated clotting time (ACT). We conducted a retrospective cohort study to determine the proportion of therapeutic first ACT in patients who received 5,000 units of UFH before primary PCI...

Cardiac allograft vasculopathy (CAV) is a serious complication of heart transplantation in adults and children. Risk factors include human leukocyte antigen mismatches, number and duration of rejection episodes, type of immunosuppression, antibody-mediated rejection, hypertension, hyperlipidemia, obesity, smoking, diabetes, cytomegalovirus infection, mode of donor brain death, donor age and ischemia/reperfusion injury. Endothelial injury and dysfunction in CAV are characterized by changes in adhesion molecules and up-regulation of major histocompatibility class II antigens followed by endothelial activation of complement C4d...

Right Heart Thrombus (RiHT) management is really controversial, and appropriate guidelines are not present for the management. In patients referring with RiHT and Pulmonary Embolism (PE), there are three ways of managing these patients. Out of the three, one is thrombectomy, which is with high risk taking in mind the comorbidities these patients have. The other is using thrombolytic which, in many cases is contraindicated or with high risk. The other less effective way is full anticoagulation. It is really controversial to choose between these ways of management and no clear approach is present...

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death in obese patients undergoing bariatric surgery (BS), but there is neither consensus nor high-level guidelines yet on VTE prophylaxis in this specific population. OBJECTIVE: We aimed to evaluate patterns of BS perioperative thromboprophylaxis practices. SETTING: French obesity specialized care centers (CSO), which are tertiary care referral hospitals for the most severe cases of obesity METHODS: A detailed questionnaire survey (11 opened, 15 closed questions) investigating their prophylactic schemes of anticoagulation (molecule, dose, weight-adjustment, duration, associated measures, follow-up) was sent to the 37 CSO...

Pregnancy-associated venous thromboembolism (PAVTE) consists of deep vein thrombosis and pulmonary embolism (PE) occurring during pregnancy or in the postpartum period. This condition is common and is a major source of morbidity in a population which is young and otherwise relatively healthy. Timely diagnosis and treatment are crucial in ensuring satisfactory patient outcomes. Diagnostic strategies for pregnancy-associated PE in particular require careful consideration of maternal and fetal risks. Low-molecular-weight heparins currently form the mainstay of treatment; however, there are uncertainties around optimal dosing of these agents in certain settings (e...

Obesity itself is associated with an increased risk of thromboembolic events. Moreover, most bariatric procedures actually are performed by laparoscopic approach, implying an increased intraabdominal pressure during the surgical procedure that may favor the development of thrombus. Therefore, bariatric surgery is considered a high-risk procedure for thromboembolic events. Actual recommendations are to include low molecular weight heparins (LMWH) and compression stockings in the primary prophylaxis of thromboembolic events...

Fibroblast growth factors (FGFs) are a superfamily of 22 proteins related to cell proliferation and tissue repair after injury. A subgroup of three proteins, FGF19, FGF21, and FGF23, are major endocrine mediators. These three FGFs have low affinity to heparin sulfate during receptor binding; in contrast they have a strong interaction with the cofactor Klotho/β-Klotho. FGF21 has received particular attention because of its key role in carbohydrate, lipids, and energy balance regulation. FGF21 improves glucose and lipids metabolism as well as increasing energy expenditure in animal models and humans...

BACKGROUND: Obese patients experience a higher risk of venous thromboembolism (VTE) than their nonobese counterparts, which may warrant a more aggressive approach to thromboprophylaxis in this population. OBJECTIVE: The purpose of this study was to compare rates of nosocomial VTE in obese patients treated with high-dose versus conventional-dose subcutaneous unfractionated heparin sodium (UFH) for thromboprophylaxis. METHODS: A retrospective, single-center, cohort study was conducted to evaluate obese, adult, hospitalized patients admitted between April 2011 and April 2014 who received heparin 5,000 or 7,500 units subcutaneously every 8 hours for thromboprophylaxis...

Compared with older agents, low-molecular-weight heparins (LMWH) and fondaparinux offer improved bioavailability and more predictable, dose-independent clearance. While routine monitoring of coagulation parameters is not usually necessary with these agents, certain populations (including pregnant patients, children, obese patients, and patients with renal impairment) may benefit from the monitoring of anti-factor Xa activity, thromboelastography, or other coagulation assays to help guide therapy. The chromogenic anti-factor Xa assay is currently the gold standard for monitoring LMWH and fondaparinux therapy...

INTRODUCTION: Skin necrosis with vitamin k antagonists are rare. They affect more frequently middle-aged and obese women, often within 10 days after initiating of treatment. They occur most often in a context of thrombophilia. CASE REPORT: An 18-year-old obese woman was treated with heparin and fluindione for a lower limb deep venous thrombosis. On day 5, the patient presented fever and skin necrosis, which extended rapidly. We identified an activated protein C resistance and a major inflammatory syndrome related to Mycoplasma pneumoniae infection...

Therapeutic enoxaparin is commonly used over heparin because of its favorable pharmacokinetic profile and ease of administration. Monitoring of the anticoagulant response, if necessary, is done with anti-factor Xa levels. Currently, it is suggested that monitoring may be beneficial in patients who are overweight and those with renal dysfunction. This study aimed to characterize the use of enoxaparin at a large-academic medical center in patients >150 kg, <45 kg and in those with renal dysfunction, and to describe the rate of anti-factor Xa monitoring in these patients...

Ana Boban, Samuel Paulus, Catherine Lambert, Cedric Hermans
Low-molecular-weight heparin (LMWH) is the anticoagulant drug class of choice for the prevention of thrombosis during pregnancy and often used for prevention of severe obstetrical complications, yet the optimal dosage is still a matter of debate. Although several studies have evaluated LMWH dose adjustment methods based on anti-Xa levels, no definitive conclusion as yet exists. This extensive retrospective study sought to address the rationale of regular anti-Xa activity monitoring in pregnant patients given LMWH prophylaxis...
