Umbilical artery thrombosis: Two case reports

Conclusion: In the late-term abortions, obstetricians should be vigilant if ultrasound imaging shows suspected umbilical vascular thrombosis or shows 1 umbilical artery when there had previously been 2. The fetus should be closely monitored and interventions implemented as early as possible to improve the prenatal detection rate of umbilical vessel thrombosis and avoid adverse pregnancy outcomes.

Abstract INTRODUCTION: Assessment of risk both for pregnancy morbidity and thrombosis in the presence of anti-phospholipid antibodies (aPL) is still a challenge in Systemic Lupus Erythematosus (SLE) patients. The Global Antiphospholipid Syndrome Score (GAPSS) takes into account the aPL profile (criteria and non-criteria aPL), the conventional cardiovascular risk factors and the autoimmune antibody profile. An adjusted model of the score (aGAPSS) excluding anti-phosphatidylserine/Prothrombin (aPS/PT), suggests that the score is able to stratify patients for their rate of events making it widely applicable in daily ...

Authors: Rostami M, Mansouritorghabeh H Abstract INTRODUCTION: COVID-19 disease has spread worldwide from December 2019 to the present day; the early stage of this disease can be associated with high D-dimer, prolonged PT, and elevated levels of fibrinogen, indicating activation of coagulation pathways and thrombosis. In this article, we analyze the levels of D-dimer in patients with COVID-19. AREA COVERED: In the current study, three databases, PubMed, Scopus, Web of Science, searched using related keywords and information extracted from articles such as location, sample size, gender, age, coagulation test val...

Mechanical heart valves may pose hemodynamic challenges leading to significant heart failure during pregnancy, especially if thrombosis or stenosis occurs. On the other hand, warfarin can have teratogenic effects, and expectant mothers may try to avoid it during pregnancy.

ConclusionThe anti ‐β2GPI/HLA –DR antibody is frequently associated with RPL. Detection of these autoantibodies is useful in understanding the pathogenesis of RPL. Our findings may provide potential new therapeutic strategies for addressing RPL in patients with obstetric APS.

AbstractPregnancy with a mechanical heart valve (MHV) is high risk for valve thrombosis because pregnancy is a hyper-coagulation state. In addition, warfarin use during pregnancy is restricted due to its fetotoxicity, and postpartum bleeding may be increased with anticoagulation. In particular, placenta previa under anticoagulation may cause massive postpartum bleeding. The optimal anticoagulation for a pregnant woman with mitral and aortic double MHVs is not known. In addition, suitable techniques for control of bleeding in a case of placenta previa under anticoagulation are not known. Thus, a case of a pregnant woman wit...

AbstractRepurposing of antirheumatic drugs has garnered global attention. The aim of this article is to overview available evidence on the use of widely used antirheumatic drugs hydroxychloroquine, methotrexate and colchicine for additional indications. Hydroxychloroquine has endothelial stabilizing and anti-thrombotic effects. Its use has been explored as an adjunctive therapy in refractory thrombosis in antiphospholipid syndrome. It may also prevent recurrent pregnancy losses in the absence of antiphospholipid antibodies. Hydroxychloroquine favourably modulates atherogenic lipid and glycaemic profiles. Methotrexate has b...

Lupus anticoagulant (LA) can be a cause of thrombosis and/or pregnancy morbidities, producing antiphospholipid syndrome (APS). An increase in thrombin generation (TG) is correlated with prothrombotic status. Several changes in TG-derived parameters have been reported in APS patients.

CONCLUSIONS: Our findings showed a profound and long-term impact of antenatal dexamethasone exposure on vascular BK via an altered epigenetic pattern from fetal stage to adulthood, advancing understanding of prolonged adverse effects and mechanisms of antenatal glucocorticoids exposure on vascular health in offspring.
