Abstrakt:	Background: Leukemia is the most common pediatric malignancy. It affects bone marrow cells especially lymphoid cell precursor. Leukemia is treated mainly by chemotherapy. Doxorubicin is a well-established chemotherapeutic agent included in treatment protocols of acute lymphoblastic leukemia. Its efficacy is often limited by its cardiotoxic side effects. Many studies are directed to overcome this problem. Black seed oil was found to have a potent cardioprotective effect. Aim of the study: To assess the protective role of black seed oil against doxorubicin-induced cardiotoxicity in children with acute lymphoblastic leukemia. Subjects and Methods: This study was carried out on 40 children with acute lymphoblastic leukemia including 20 patients under doxorubicin therapy and black seed oil 80 mg/kg/dose divided into 3 doses starting at the same moment of beginning of doxorubicin infusion therapy and continued for 1 week after each doxorubicin dose [group I] and 20 patients under doxorubicin and placebo for 1 week after each doxorubicin dose [group II]. They underwent conventional echo-Doppler measures of left ventricular systolic and diastolic functions and pulsed wave tissue Doppler of lateral mitral annulus. Results: No significant differences were found in parameters of electrocardiograph including S-T segment and Q-T interval either before or after doxorubicin therapy. No significant differences in echocardiographic parameters were found between group I and group II before therapy. Non-significant changes in parameters of diastolic function [E/A ratio or e/a ratio] were found after doxorubicin therapy in group I and II, but there were significant reduction in parameters of systolic function [EF, FS and s wave] after doxorubicin therapy more in group II than group I. Conclusion and recommendation: From this study, we concluded that: Black seed oil improves some cardiac side effects of doxorubicin as shown by better systolic functions in children with acute lymphoblastic leukemia who were treated with Doxorubicin and black seed (group I) than in children with acute lymphoblastic leukemia who were treated with doxorubicin alone with no black seeds (group II), and therefore multi center studies is recommended to be done before we can recommend the use of black seed oil as an adjuvant therapy in patients with acute lymphoblastic leukemia under doxorubicin-based treatment protocol.
