Summary: Global coagulation assays and thromboelastometry can differentiate patients with moderate hemophilia based on joint health scores, annual factor consumption, and history of orthopedic surgery. These assays may help in predicting the bleeding phenotype in patients with moderate hemophilia.

Summary: Haemophilia A and B are X-linked hemorrhagic disorders caused by gene variants in theF8andF9genes. The study aimed to determine whether low FVIII or FIX levels in haemophilia carriers could be related to XCI pattern and bleeding symptoms. Results showed a statistical association between XCI pattern and FVIII and FIX levels in haemophilia carriers, suggesting that skewed XCI may contribute to the low expression of clotting factor levels and bleeding symptoms.

Summary: Haemophilia is an inherited bleeding disorder caused by deficiency of coagulation factor VIII or IX. Traditional treatments involve replacing the missing factors, but face challenges due to short half-life and inhibitor development. Recent advances, such as factor concentrate half-life extension and gene therapy, offer new hope for improved quality of life and potential cure for haemophilia.

Summary: Although the relationship between physical activity (PA) and bleeding phenotype in people with haemophilia remains unclear, improvements in treatment regimens over recent decades have led to increased levels of physical activity, especially among those with severe haemophilia. Further research using validated outcome measures of PA and more robust reporting of bleeds and treatment regimens is needed in this rapidly evolving era of new treatments for people with haemophilia.

Summary: The study developed a PK-PD approach for modelling recurrent bleeding events in severe haemophilia patients and found that the new method outperforms existing methods in terms of bias and mean squared error by investigating the relationship between factor VIII and risk of a bleed using all bleeding times.

Summary: The evidence from randomized controlled trials suggests that prophylaxis, compared to on-demand treatment, can reduce bleeding frequency and improve joint function, pain, and quality of life in previously-treated people with hemophilia. However, prophylactic regimens did not show significant differences in protection from bleeding, and dose optimization could potentially enhance efficacy. Well-designed RCTs and controlled studies are needed to establish optimal and cost-effective treatment regimens.

Summary: This study investigated the validity of FVIII:C/VWF:Ag ratio and FVIII:C analyses as screening tests for haemophilia A carriers. The results showed that the FVIII:C/VWF:Ag ratio had high specificity but may also induce false-negative results.

Summary: Joint health and treatment modalities in Nordic patients with moderate haemophilia A and B were evaluated using Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) and Haemophilia Joint Health Score (HJHS). The study found a strong correlation between HEAD-US and HJHS, with 24% of patients showing discordant scores. Subclinical pathology was detected in 5% of patients using HEAD-US.

Summary: This study investigates the risk factors and management experience of factor FIX inhibitors in Chinese patients with hemophilia B. The researchers found that large deletions in the F9 gene were significantly associated with inhibitor development. Additionally, low-dose immune tolerance induction therapy may be a feasible approach for eradicating FIX inhibitors.

Summary: This pilot study aimed to investigate the effects of statins in addition to anticoagulation in patients with acute VTE, but found that statins did not significantly reduce thrombin generation. Although atorvastatin significantly reduced LDL levels at 3 months, it had no impact on d-dimer or high-sensitivity-C reactive protein. The study was terminated early due to low recruitment rate and barriers to enrollment.

Summary: This study diagnosed a family with Factor V east Texas bleeding disorder and identified the FVET variant associated with bleeding symptoms. The research suggests that elevated plasma TFPI alpha may be the primary cause of bleeding and effective therapies could include the use of an anti-TFPI antibody or factor VIIa. Increased awareness and testing for bleeding disorders related to F5 exon 13 variants and elevated plasma TFPI are necessary.

Summary: Persons with mild hemophilia A can improve their coagulation function by using intranasal desmopressin prior to sports participation, although the duration of improvement is short. Moderate-intensity aerobic exercise can also improve coagulation function. Combining exercise with desmopressin treatment can achieve better results.

Summary: The study aimed to investigate the role of PAR-1 in the pathogenesis of ARN. Through observations and evaluations of 5/6NE rats treated with different agents, it was found that both activation and blockage of PAR-1 led to glomerular hematuria and subsequent acute tubular epithelial cell injury.

Summary: Life expectancy for persons with hemophilia has increased due to advances in treatment, but they are now more likely to be affected by conditions associated with aging. This study analyzed the prevalence of bleeding and thrombotic events in hemophilia populations compared to the general population. The results showed consistently higher rates of bleeding events in hemophilia populations, while the prevalence of arterial thrombosis varied.

Summary: The purpose of this study was to evaluate the prognostic value of fluorine-18-fluorodeoxyglucose PET/CT imaging of venous inflammation for predicting venous thromboembolism (VTE) occurrence in pediatric, adolescent, and young adult patients with lymphoma. The study found that PET/CT imaging could detect venous inflammation and it was associated with the occurrence of VTE.

Summary: This study aims to describe treatment patterns and outcomes in pediatric patients with arterial thrombosis (AT) and explore predictors for complete thrombus resolution or long-term complications. The results showed that the duration of anticoagulation varied greatly, and a significant proportion of patients developed long-term sequelae secondary to arterial insufficiency. In addition, patients with infection-associated AT were more likely to have long-term complications.

Summary: Recent clinical trials have shown the safety and efficacy of direct oral anticoagulants (DOACs) for the treatment of venous thromboembolism (VTE) in pediatric patients. However, there is limited evidence on the use of andexanet alfa and prothrombin complex concentrates (PCC) for reversing the effects of direct oral factor Xa inhibitors (DXIs) in this population. A survey of pediatric hematology experts revealed that some would consider andexanet alfa and PCC as potential options for managing life-threatening bleeding in children on DXIs, but further investigation is needed.
