Investigate of Haemostatic and Fibrinolytic System Parameters among Sickle Cell Anaemia Patients in the Khartoum State

Abstract
Introduction: A sickle cell anaemia one of a haemoglobinopathy, which constituted as a model for genetically inherited disorders, the course of the disease involves may crises, the investigation of hemostatic components as fibrinogen and fibrinolysis as D-dimer, reflect the overall hemostatic status in the sickle cell anaemia patients. Aim: To investigates hemostatic and fibrinolytic system parameters among sickle cell anaemia patients in the Khartoum state. Methods: The study was conducted in Khartoum state, in JafarIbn Auf Reference Hospital for children as descriptive case-control, a laboratory-based study from 2017-18, specimens were collected randomly of the study population with irrespective to age and gender, blood draw in tri-sodium citrate container, the ethical and consent were obtained. The fibrinogen level was estimated by CA51 semi-automated coagulation analyzer optically based, and the D-dimer were assayed by MISPA-i2, a nephelometric based, the results for each parameter were recorded and using statistical package for the social sciences (SPSS) software for analysis by independent T-test and the statistical significance > 0.05. Results: A hundred participants fifty as study group (HbSS) sickle cell anemic Sudanese child clinically and laboratory-confirmed and fifty healthy as the control group, in comparing a mean of fibrinogen show statistically insignificant (P value 0.645) study group 291.1 ± 107.8 mg/dL and control group 283.4 ± 49.1 mg/dL, but there was a significant difference in comparing a mean of D-dimer in study group 0.56 ± 0.33 μg/mL and control group 0.33 ± 0.14 the P. value 0.00015. Conclusion: The level of D-dimer may be used as a hypercoagulability biomarker in comparison to the level of fibrinogen level for sickle cell anaemia Sudanese child.
