Abstract
Patients with sickle cell disease (SCD) show activation of the blood coagulation. The purpose of the current study was to detect the prevalence of factor V Leiden (G1691A) and prothrombin gene (G20210A) mutations in a group of Egyptian children with SCD, and to clear out their possible role as genetic risk factors for vaso-occlusive crises (VOC) in SCD. The current study included fifty Egyptian SCD children and fifty age and sex matched healthy children as a control group. Genotyping was performed by polymerase chain reaction restriction fragment length polymorphism technique. Heterozygous factor V Leiden was significantly higher in the SCD patients (30 %) compared to controls (16 %), while there was no statistical difference between the two groups regarding heterozygous prothrombin gene (G20210A) mutation. Factor V Leiden conferred increased risk of VOC in SCD patients (OR = 1.7, 95 %CI = 1.01–3.43). Screening for factor V Leiden in SCD patients is recommended to verify patients at higher risk of VOC.
