Hereditary spherocytosis (HS) is a familial hemolytic disorder associated with a variety of mutations that lead to defects in red blood cell (RBC) membrane proteins. There is increasing evidence that hypercoagulability occurs in chronic hemolytic anemia. In this study, changes in the coagulation profile in children with HS were investigated using rotational thromboelastometry. A total of 21 children with HS and 28 healthy children were enrolled in the study between October 2010 and October 2018. Complete blood count, prothrombin time, activated partial thromboplastin time, and fibrinogen level were ascertained, while rotational thromboelastometry assays were used to measure and analyze coagulation time, clot formation time, and maximum clot firmness. There was no difference between the 2 groups in terms of age and sex. The values of hemoglobin and RBC in the patient group were statistically significantly lower than those in the control group (P<0.01, <0.0001, respectively), and the values of platelet count, mean corpuscular hemoglobin concentration, and RBC distribution width were statistically significantly higher than those in the control group (P<0.05, 0.001, <0.0001, respectively). There was no statistically significant difference between the 2 groups in terms of prothrombin time, activated partial thromboplastin time, fibrinogen levels, coagulation time, clot formation time, and maximum clot firmness values. In contrast to other chronic hemolytic anemias, no predisposition to hypercoagulability has been shown in the coagulation profile of children with HS without splenectomy.
