Fostering a healthier generation of children with sickle cell disease through advancements in care.

Abstract

Sickle cell disease (SCD) is an inherited disorder of hemoglobin that affects tens of millions of individuals worldwide. Without preventive and disease-modifying therapy, SCD results in many acute and chronic complications impacting both quality and length of life. We are currently in a new generation of SCD care in high resource settings due to recent advancements in care. Universal newborn screening (NBS) for SCD with associated parental education and preventive care significantly improved mortality rates. Beginning in the 1990s, hydroxyurea emerged as a promising pharmacologic treatment for SCD due to its ability to increase the amount of fetal hemoglobin. It is now the mainstay of treatment, with strong recommendations to begin as early as the first year of life with the goal of reducing most short- and long-term complications and allowing for a normalized quality of life. More recently, gene therapy has come to the forefront in SCD and brings the hope of a cure for many patients. In 2023, the FDA approved two cell-based gene therapies for patients with SCD. The future is bright for patients with SCD, and the current generation of affected children will expectantly be able to grow up free of suffering and severe, frequent pain.
