Abstract

Hydroxyurea (HU) is a disease-modifying therapy with significant clinical and laboratory efficacy among individuals living with sickle cell anaemia (SCA). This is evident through increased fetal haemoglobin, higher packed cell volume, improved red cell hydration, reduced leukocytes, and platelet function. The effect on the coagulation pathway and pathophysiologic mechanism remains unclear, especially in children living with SCA. This study evaluated the coagulation profile using D-dimer and thrombin antithrombin complex (TAT) in children with SCA.
