Recent progress in the treatment of sickle cell disease: an up-to-date review

Abstract

Background Sickle cell disease is a fatal systemic condition characterized by acute painful episodes, persistent anemia, ongoing organ damage, organ infarction, and a markedly shorter average lifetime. It first appeared in the tropics' malarial zones, where carriers benefit from an evolutionary advantage by being shielded from malaria death. Due to demographic shifts, this crisis now affects people all over the world. In higher-income areas, such as vast swaths of Europe and North and South America, more children are born with the syndrome. Main body Over the last 10 years, a clearer knowledge of the change from fetal to adult hemoglobin has evolved. Further investigation into chimerism, genomics, mixed gene editing, and therapeutic reactivation of fetal hemoglobin has produced very promising findings. Between 2017 and 2019, three innovative medications for sickle cell disease were approved by the FDA thanks to previous advances, while many more treatments are now under development. Short conclusion To improve patient outcomes, various innovative medications that were created in the late 1990s and utilized to treat sickle cell disease are examined in this study. In our appraisal, we'll also focus on the most important developments of the decade.
