Background And Objectives: The aim of this study was to investigate the T helper (Th) to T cytotoxic (Tc) ratio in children suffering from type A hemophilia disease and to evaluate the correlation of this ratio with disease severity.
Material And Method: Two mls of EDTA anti coagulated whole blood was collected. Immunophenotyping of lymphocytes count was carried out by FACS analysis using a double CD4 and CD8 kit. The mean ± SD of absolute numbers of CD4 and CD8 lymphocytes/ml was calculated and the ratio of CD4/CD8 was evaluated by statistical method.
Results: Among 80 type A hemophilia patients, 66 (82.5%) were male. The mean age was 15 ± 3.51 years. 12 (15%) of them were suffering from mild disease and 68 (85%) had sever disease. The CD4 /CD8 ratio was obtained between 0.45 and 1.44 with mean1.79 ± 0.78. The correlation between this ration and disease severity was 0.019.
Conclusion: The results showed that CD4/CD8 ratio has correlation with disease severity in type A hemophilia patients, however there was no association between this ratio and gender.

Long-term correction of hemophilia A via integration of a functionally enhanced FVIII gene into the AAVS1 locus by nickase in patient-derived iPSCs.

Hemophilia A (HA) is caused by mutations in coagulation factor VIII (FVIII). Genome editing in conjunction with patient-derived induced pluripotent stem cells (iPSCs) is a promising cell therapy strategy, as it replaces dysfunctional proteins resulting from genetic mutations with normal proteins. However, the low expression level and short half-life of FVIII still remain significant limiting factors in the efficacy of these approaches in HA.
View Article and Find Full Text PDFIntroduction: Hereditary bleeding disorders stem from the absence or insufficient levels of particular clotting proteins, essential for facilitating coagulation in the clotting cascade. Among the most prevalent are hemophilia A (deficiency of Factor VIII), hemophilia B (deficiency of Factor IX), and von Willebrand disease. Management of pharmacoresistant epilepsy is more difficult in a patient with bleeding disorder due to increased risk of bleeding during surgery.

Background: Hereditary angioedema (HAE) is a rare genetic disease characterized by recurrent episodes of cutaneous or subcutaneous edema. There is clinical need for treatments that reduce the rate of HAE attacks in patients.
Objectives: Primary objectives were to evaluate the effectiveness of lanadelumab on attack free rate (AFR; proportion of patients who had zero HAE attacks), and on every two weeks (Q2W) and every four weeks (Q4W) adjustments on AFR.

Introduction: Maintaining the balance between procoagulant and anticoagulant factors is essential for effective haemostasis. Emerging evidence suggests a modulation of bleeding tendency by factors in the anticoagulant and fibrinolytic systems.
Aim: This study investigates the clinical and laboratory characteristics of a family with combined von Willebrand disease (VWD) and antithrombin (AT) deficiency.
