Abstract
Sickle cell disease (SCD), the most common autosomal recessive genetic disorder, affects the hemoglobin (Hb) chains in human red blood cells. It is caused by mutations in the β-globin genes, leading to the production of hemoglobin S, which results in the formation of sickle-shaped red blood cells (RBCs). These abnormal cells cause hemolysis, endothelial damage, and small vessel occlusion, leading to both acute and long-term complications. According to the World Health Organization's 2008 estimates, SCD affects approximately 2.28 per 1000 individuals globally. Despite this high prevalence, therapeutic advancements have been slow. For many years, the only FDA-approved medications for managing SCD complications were hydroxyurea and deferiprone. However, recent years have seen the approval of several new therapies, including L-glutamine (2017), voxelotor and crizanlizumab (2019), as well as exagamglogene autotemcel (Casgevy) and lovotibeglogene autotemcel (Lyfgenia) (2023). These treatments have proven effective in managing both the acute and chronic effects of SCD, including hemolytic anemia, chronic pain, stroke, vaso-occlusive crises, and multiple organ damage syndromes. This review explores the mechanisms of action, practical considerations, and side effects of these emerging therapies, drawing from a comprehensive search of databases such as PubMed, Medline, and Cochrane.
