Idiopathic Thrombocytopenia Purpura Masking Hodgkin Disease: A Paraneoplastic Syndrome or Simply a Mere Association?
We report a 74-year-old female who presented to the emergency department complaining of bruising and stroke-like symptoms. She underwent a negative stroke work-up but was found to have profoundly low platelets and splenomegaly on examination. An abdominal CT scan was ordered, showing pelvic lymphadenopathy. Lymphoma was suspected. However, subsequent bone marrow and lymph node biopsies showed no evidence of this. She was treated for immune thrombocytopenia purpura (ITP) to no avail while a lymphoma work-up continued. Months later, a third and final lymph node biopsy yielded evidence of Hodgkin disease (HD) and she began tr...

The role of ADAMTS13 testing in the diagnosis and management of thrombotic microangiopathies and thrombosis
ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif, 13) is a metalloprotease responsible for cleavage of ultra-large von Willebrand factor (VWF) multimers. Severely deficient activity of the protease can trigger an acute episode of thrombotic thrombocytopenic purpura (TTP). Our understanding of the pathophysiology of TTP has allowed us to grasp the important role of ADAMTS13 in other thrombotic microangiopathies (TMAs) and thrombotic disorders, such as ischemic stroke and coronary artery disease. Through its action on VWF, ADAMTS13 can have prothrombotic and proinflammatory properties, not only ...

Variable Clinical Presentation of Congenital Thrombotic Thrombocytopenic Purpura in a Large Cohort of Patients Carrying a New Mutation in the CUB1 Domain of ADAMTS13 Gene
Conclusion:To the best of our knowledge, this is one of the largest congenital TTP cohorts described in the literature. This cohort is unique due to the fact that all members carry the same, previously unreported, ADAMTS13 gene mutation in the CUB1 domain of the gene. Our findings support an assumption that environmental and hereditary modifiers may influence disease course. Further research of the involved families may enable us to expand the understanding of the pathophysiology and develop better treatment options for this understudied rare condition.DisclosuresNo relevant conflicts of interest to declare.

Efficacy and Safety of Pomalidomide in Combination with Prednisone in Patients with Myelofibrosis and Anemia -- Final Results of a Prospective Phase 2 Study
CONCLUSION:Pomalidomide with prednisone is safe therapy with good anti-anemia activity in patients with MF. It could lead to transfusion independence in one third of patients for a median duration of about 30 months.

N-Acetylcysteine (NAC) for the Prevention of Liver Failure in Heat Injury-Mediated Ischemic Hepatitis.
Authors: Will JS, Snyder CJ, Westerfield KL Abstract Exertional Heat Illness with associated ischemic hepatitis (IH) is a common occurrence among military trainees; however, few specific therapies exist if unresponsive to appropriate supportive measures. A 27-year-old basic combat trainee presented with altered mental status, renal insufficiency, rhabdomyolysis, and a core temp of 107.9 °F after collapsing during a run, leading to the diagnosis of heat stroke. While the patient's azotemia and creatinine kinase levels rapidly improved with aggressive intravenous hydration, transaminases continued to increase to nea...

Characterization and treatment of congenital thrombotic thrombocytopenic purpura
In conclusion, prespacer mutations are associated with earlier development of cTTP symptoms. Prophylactic ADAMTS13 replacement decreases the risk of end-organ damage such as ischemic stroke and resolved previously unrecognized symptoms in patients with nonovert disease.

Preventable Cases of Oral Anticoagulant-Induced Bleeding: Data From the Spontaneous Reporting System
Conclusion: Our findings describe the most reported risk factors for preventability of oral anticoagulant-induced bleedings. These factors may be useful for targeting interventions to improve pharmacovigilance activities in our regional territory and to reduce the burden of medication errors and inappropriate prescription. Introduction Oral anticoagulant therapy is widely used for the prevention of stroke and systemic embolism in patients with atrial fibrillation, or for the prevention and treatment of deep vein thrombosis and pulmonary embolism (Raj et al., 1994; Monaco et al., 2017). Oral anticoagulants can be di...

The Emerging Threat of (Micro)Thrombosis in COVID-19 and Its Therapeutic Implications.
Abstract The recent emergence of SARS-CoV-2 and the ensuing global pandemic has presented a health emergency of unprecedented magnitude. Recent clinical data has highlighted that COVID-19 is associated with a significant risk of thrombotic complications ranging from microvascular thrombosis, venous thromboembolic disease and stroke. Importantly, thrombotic complications are markers of severe COVID-19 and are associated with multi-organ failure and increased mortality. The evidence to date supports the concept that the thrombotic manifestations of severe COVID-19 is due to the ability of SARS-CoV-2 to invade endo¬...

Association between platelet counts and morbidity and mortality after endovascular repair for type B aortic dissection.
This study aimed to assess the association of postoperative platelet counts with early and late outcomes after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD). We retrospectively evaluated 892 patients with TBAD who underwent TEVAR from a prospectively maintained database. Postoperative nadir platelet counts were evaluated as a continuous variable, and a categorical variable (thrombocytopenia), which was defined as platelet count≤ the lowest 10% percentile (108 × 109/l). Multivariable logistic regression analyses were conducted to assess the impact of postoperative thrombocytopenia on e...

Outcomes of systemic anticoagulation with bivalirudin for Impella 5.0
Int J Artif Organs. 2021 Jul 12:3913988211032238. doi: 10.1177/03913988211032238. Online ahead of print.ABSTRACTTemporary mechanical circulatory support (tMCS) devices are used for the management of cardiogenic shock. The Impella 5.0 (Abiomed; Danvers, MA) (IMP5) is a commonly used, surgically implanted, tMCS device that requires systemic anticoagulation and purge solution to avoid pump failure. To avoid heparin-induced thrombocytopenia (HIT) from unfractionated heparin (UFH) use, our program has explored the utility of bivalirudin (BIV) for systemic anticoagulation in IMP5. This single center, retrospective study included...
