Iliopsoas hematoma in patients with COVID-19 on low-molecular-weight heparin treatment.

Patients with COVID-19 are at high risk of thromboembolic events; for this reason, the use of heparin is largely recommended but, in addition to thrombotic complications, bleeding is a significant cause of morbidity in patients with COVID-19. Idiopathic iliopsoas hematoma is a very rarely described hemorrhagic complication in patients with COVID-19. We report here two cases of iliopsoas hematoma in male patients with COVID-19 and being treated with heparin.

Use of Catridecacog in a patient with severe Factor XIII deficiency undergoing surgery.

Despite many articles regarding the antihemorrhagic treatment and prophylaxis, there is a lack of experience about how to best conduct major surgical procedures in patients with congenital factor XIII (FXIII) deficiency. Here we report a case of surgery (right inguinal hernia, complicated by heaviness and pain) performed in a patient with FXIII deficiency, receiving recombinant FXIII prophylaxis (Catridecacog 35 UI/kg every 28±2 days). Our experience shows that Catridecacog can be used safely and effectively not only for continued prophylaxis but also in surgery and adds to the very limited body of evidence currently available on surgery in this bleeding disorder.

Efficacy of Octocog Alfa (Advate) in a Child with Type 3 von Willebrand Disease and Alloantibodies.

Von Willebrand disease (VWD) is the most frequent inherited bleeding disorder and is caused by either a quantitative and/or qualitative defect of the multimeric glycoprotein vonWillebrand factor (VWF).[..

Utility of the clinical practice of administering thrombophilic screening and antithrombotic prophylaxis with low-molecular-weight heparin to healthy donors treated with G-CSF for mobilization of peripheral blood stem cells.

The aim of the study was to verify the utility of the clinical practice of administering thrombophilic screening and antithrombotic prophylaxis with low-molecular-weight heparin to healthy donors receiving granulocyte colony-stimulating factor to mobilize peripheral blood stem cells. Thrombophilia screening comprised of testing for factor V Leiden G1691A, prothrombin G20210A, the thermolabile variant (C677T) of the methylene tetrahydrofolate reductase gene, protein C, protein S, factor VIII and homocysteine plasmatic levels, antithrombin III activity, and acquired activated protein C resistance. We investigated prospectively 72 white Italian healthy donors, 39 men and 33 women, with a median age of 42 years (range, 18-65).

Role of hyperhomocystinemia in retinal vascular occlusive disease.

Elevated plasma homocysteine (Hcy) level is considered a risk factor for vascular diseases. In recent years, many scientific reports have suggested that hyperhomocystinemia may be associated with an increased risk of retinal vascular occlusive disease (RVOD). The prevalence of elevation of homocysteine in patients with a recent retinal vascular occlusion was compared to a health control group in this study.

Genetic prothrombotic risk factors in women with unexplained pregnancy loss.

Introduction: Inherited thrombophilia has been associated with unexplained recurrent pregnancy loss (RPL) and stillbirth. This thrombotic tendency can manifest as thrombotic lesions in the placenta, and may lead to abortion and stillbirth. The aim of our case-control study was to investigate the prevalence of FVL and FII G20210A in women with adverse pregnancy outcome, compared to the prevalence of the same mutations in our health control group.
