Primary Bone Marrow Hodgkin's Lymphoma Debuting As Hemophagocytic Lymphohistiocytosis in a Patient With HIV.

The development of Hodgkin's lymphoma (HL) is a known complication in patients with human immunodeficiency virus (HIV) infection. Extranodal involvement, specifically primary bone marrow Hodgkin's lymphoma (PBMHL) is a rare manifestation that has been reported in HIV-positive patients and may represent a distinct entity from HIV-associated HL. We present a case of PBMHL presenting with hemophagocytic lymphohistiocytosis (HLH) in an HIV-positive patient.

Observational cohort study of long-term outcomes of liver transplantation in haemophilia.

Introduction: Gene therapy is now a reality for individuals with haemophilia, yet little is known regarding the quality-of-life impact of factor correction. As few data exist, and recognizing the analogy to liver transplantation (OLTX), we identified OLTX+ and OLTX- men in the ATHNdataset to compare post-OLTX factor VIII and IX on quality of life (QoL) by Haem-A-QoL and PROMIS-29.

Methods: OLTX- were matched to OLTX+ by age, race, and haemophilia type and severity.

Recombinant von Willebrand factor and tranexamic acid for heavy menstrual bleeding in patients with mild and moderate von Willebrand disease in the USA (VWDMin): a phase 3, open-label, randomised, crossover trial.

Background: Heavy menstrual bleeding occurs in 80% of women with von Willebrand disease and is associated with iron deficiency and poor response to current therapies. International guidelines indicate low certainty regarding effectiveness of hormonal therapy and tranexamic acid. Although von Willebrand factor (VWF) concentrate is approved for bleeds, no prospective trials guide its use in heavy menstrual bleeding.

Recombinant vs plasma-derived von Willebrand factor to prevent postpartum hemorrhage in von Willebrand disease.

von Willebrand disease (VWD) is a congenital bleeding disorder characterized by deficient or defective von Willebrand factor (VWF). Among women with VWD, postpartum hemorrhage (PPH) is common. Treatment options at delivery include plasma-derived VWF (pdVWF) and recombinant VWF (rVWF).

Hormones and thrombosis: risk across the reproductive years and beyond.

Endogenous and exogenous hormones have significant effects on coagulation and may tip the hemostatic balance toward thrombosis. The endogenous hormonal changes in pregnancy and polycystic ovary syndrome, and exogenous hormonal contraception, menopause replacement, and transgender cross-hormone replacement may increase thromboembolism risk. Using the lowest effective dose is critical for prevention, but once thrombosis occurs, anticoagulation may be required, in some, long term.

Prevalence and correlates of thrombosis in adults with immune thrombocytopenia: An NIS study.

Background: Immune thrombocytopenia (ITP) is increasingly recognized as a thrombophilic disorder. However, no further investigation of risk factors has been conducted to date. This study evaluated classic and disease-specific correlates of thrombosis among ITP patients.

An investigational RNAi therapeutic targeting antithrombin for the treatment of hemophilia A and B.

Fitusiran is an RNA interference therapeutic that targets antithrombin (AT) in the liver and interferes with AT translation by binding and degrading messenger RNA-AT, thereby silencing AT gene expression and preventing AT synthesis. In both preclinical and clinical studies, AT knockdown results in dose-dependent AT lowering when fitusiran is given weekly or monthly subcutaneously. In clinical trials, fitusiran dose escalation has resulted in improved thrombin generation and clinical hemostasis as measured by reduction in annualized bleed rate.

Gene therapy in hemophilia A: a cost-effectiveness analysis.

Gene therapy provides a potential phenotypic cure for hemophilia, yet the cost of this novel treatment is high, tempering enthusiasm and raising questions regarding cost vs benefit. To evaluate the cost-effectiveness of gene therapy treatment of severe hemophilia A compared with prophylaxis with factor VIII (FVIII), we developed a Markov state-transition model to estimate the costs and effectiveness of severe hemophilia A treatment strategies from a United States health care system perspective. Quality-adjusted life-years (QALYs) were the effectiveness measure.

Feasibility of the Von Willebrand disease PREVENT trial.

Background: Despite treatment, women with von Willebrand disease (VWD) have lower von Willebrand factor (VWF) levels and greater blood loss at delivery than controls. Current weight-based dosing does not account for the ~1.5-fold increase in blood volume in pregnancy.
