A 7-years-old child who developed unprovoked deep vein thrombosis (DVT) and pulmonary embolism (PE) was tested for inherited thrombophilia. Protein C (PC) antigen level (87 %) and PC coagulometric and amidolytic activities (12 % and 11 %, respectively) were consistent with a homozygous PC type IIA phenotype.The patient was carrier of two heterozygous missense mutations causing p.Arg32Cys substitution associated with a type I PC defect ("null allele", from the paternal side) and p.Gly433Ser substitution responsible for a type IIA PC defect (from the maternal side)...

Homocysteine (Hcy) is thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of the folic acid, vitamins B6 and B12. Consequently, the level of the total Hcy in the serum is influenced by the presence or absence of these vitamins. An elevated level of the Hcy, hyperhomocysteinemia (HHcy) and homocystinuria are connected with occlusive artery disease, especially in the brain, the heart, and the kidney, in addition to venous thrombosis, chronic renal failure, megaloblastic anemia, osteoporosis, depression, Alzheimer's disease, pregnancy problems, and others...

PURPOSE: Otogenic lateral sinus thrombosis (OLST) is an intracranial, potentially life-threatening complication of acute and chronic otitis media. Since congenital thrombophilic disorders are risk factors for cerebral venous thrombosis, OLST may be related to thrombophilia. The aim of our study was twofold: to evaluate whether patients who suffered from OLST in childhood also have thrombophilia, and whether these patients experienced thromboembolic episodes in future years. STUDY DESIGN: Retrospective case series...

During pediatric kidney transplant, surgical challenges occasionally occur. In particular, vascular anastomosis should be considered for children with small body weight < 12 kg, multiple renal arteries, vascular anomaly, and inferior vena cava occlusion. In pediatric patients, a living-donor renal graft is usually donated from a parent. Therefore, the renal artery and vein are too large to be anastomosed with the recipient's internal iliac artery and external iliac vein. In children who are > 12 kg, the renal artery and vein could be anastomosed with the external iliac artery and the external iliac vein...

Venous thrombosis (VTE) in children is gaining increased awareness and apart from underlying medical conditions, recently reported systematic reviews on pediatric VTE (70% provoked) have shown significant associations between thrombosis and presence of inherited thrombophilic risk factors (IT), such as protein C-, protein S- and antithrombin deficiency, mutations of factor 5 (F5: rs6025) and factor 2 (F2: rs1799963), even more pronounced when combined IT were involved. Although we have learned more about the pathophysiology of VTE with the increased discovery of IT evidence is still lacking as to whether IT influence the clinical outcome in pediatric VTE...

Thrombosis and hemorrhage are serious complications in pediatric patients with solid tumors, and enhanced fibrinolysis associated with disseminated intravascular coagulation (DIC) is often observed. Fibrinolytic enzymes also play an important role in metastasis. Limited information is available, however, on the assessment of overall hemostatic function in children with malignant solid tumors. Methods We have investigated comprehensive hemostatic potential in these circumstances using simultaneous thrombin/plasmin generation assay (T/P-GA)...

BACKGROUND: Enoxaparin may be used to prevent central venous catheter-related thrombosis in patients with CHD. We aimed to determine whether current enoxaparin dosing regimens effectively achieve anti-factor Xa concentrations within prophylactic goal ranges in this patient population. METHODS: We implemented a formal protocol aimed at reducing central venous catheter-related thrombosis in children with CHD in January, 2016. Standard empiric prophylactic enoxaparin dosing regimens were used - for example, 0...

Eltrombopag is currently the only US Food and Drug Administration-approved thrombopoietin receptor agonist for the treatment of chronic immune thrombocytopenia (ITP) in children. This oral, once-per-day therapy has shown favorable efficacy and adverse effect profiles in children. Two multicenter, double-blind, placebo controlled clinical trials (PETIT [Efficacy and Safety Study of Eltrombopag in Pediatric Patients With Thrombocytopenia From Chronic Idiopathic Thrombocytopenic Purpura (ITP)] and PETIT2 [Study of a New Medication for Childhood Chronic Immune Thrombocytopenia (ITP), a Blood Disorder of Low Platelet Counts That Can Lead to Bruising Easily, Bleeding Gums, and/or Bleeding Inside the Body]) demonstrated efficacy in raising platelet counts, reducing bleeding, and reducing the need for concomitant ITP therapies with relatively few adverse effects...

In primary chronic immune thrombocytopenia, long-term response to splenectomy, with 60% of patients enjoying a treatment-free life, is higher when compared with rituximab and similar to that with continuous thrombopoietin-receptor agonists (TPO-RA) administration. Splenectomy should continue to be offered to patients failing initial treatments in the absence of increased surgery-related risks. The higher lifelong safety concerns with splenectomy (increased risk of infection, shared in part with rituximab, and of thrombosis, in common with TPO-RA) and a mortality <1-2%, justify postponing surgery to the chronic phase, when spontaneous remissions are rarer...

Multiple observational studies have identified risk factors for venous thromboembolism (VTE) in hospitalized children, but very few interventional studies have assessed the safety and efficacy of thromboprophylaxis in this population. In recent years, however, evidence in pediatric VTE risk stratification has grown considerably. This has led to the conception of a pediatric subpopulation-specific risk-based paradigm for mechanical and pharmacological thromboprophylaxis in hospitalized children. More research is required to validate and further refine pediatric subpopulation-specific risk models and to subsequently investigate risk-stratified thromboprophylaxis strategies for hospitalized children...

BACKGROUND: Adult Wilms tumor (WT, nephroblastoma) is a rare, but well-described renal neoplasm. Although inferior vena cava tumor thrombosis is present in up to 10% of Wilms tumors in childhood, only few cases of this clinical manifestation in adults have been reported. To the best of our knowledge, this is the first case of adult WT infiltrating into inferior vena cava (IVC) with concomitant distal deep vein thrombosis. CASE PRESENTATION: A 28-year-old male patient with gross hematuria and right flank pain was diagnosed with right kidney tumor penetrating to IVC...

Neural tube defects occupy second place in frequency after the defects of the cardiovascular system. The folate metabolism violation and hyperhomocysteinemia in women are proved to be the leading risk factors for the NTD of the fetus. Polymorphism of the 5,10-methylenetetrahydrofolate reductase gene (MTHFR) is a genetic determinant of folate metabolism violation. Admission of folic acid in a standard dose of 0.4 mg and / or the use of fortified foods does not allow reaching the protective level of folic acid if there is a mutation of the MTHFR gene or when several risk factors combine, which requires a higher dose of folic acid...

BACKGROUND: Postoperative chylothorax in children is associated with an increased risk of vascular thrombosis, hypothesized to be from loss of antithrombin into chylous fluid resulting in a hypercoagulable state. In adults, an increased thrombotic risk with chylothorax has not been described. Adults undergoing Ivor-Lewis esophagogastrectomy have two strong thrombotic risk factors-active malignancy and postoperative state-allowing for relative homogeneity in baseline thrombotic risk; therefore, we studied the association of chylothorax with thrombosis in this population...
