Sickle Cell Disease

Sickle cell disease is an inherited hemoglobinopathy characterized by the presence of abnormal hemoglobin that causes red blood cells to assume a rigid, sickle shape under stress conditions. These distorted cells lead to chronic hemolytic anemia, vascular occlusion, and multi-organ complications. Clinical manifestations include recurrent pain episodes, infections, acute chest syndrome, stroke, and progressive organ damage. Early diagnosis through newborn screening has improved survival and long-term outcomes. Management focuses on preventive care, pain control, infection prophylaxis, and disease-modifying therapies. Advances in pharmacological treatments, transfusion protocols, and curative approaches such as stem cell transplantation have transformed disease management. Recent breakthroughs in gene-based therapies offer hope for long-term disease correction. Despite these advances, disparities in access to care persist globally. Continued research and public health initiatives aim to improve outcomes, reduce complications, and enhance the quality of life for individuals living with sickle cell disease.
