Sickle cell anemia and death rate: Is it lethal?
Sickle cell anemia (SCA), a severe form of sickle cell disease (SCD), affects thousands of individuals in the United States. Recent years have seen improvements in SCA survival rates, with 95% of people with SCA reaching adulthood [1]. However, the condition still poses significant challenges, leading to a reduced life expectancy compared to the general population.
The root of the problem lies in the sickle-shaped red blood cells characteristic of SCA. These cells have a shorter lifespan, leading to a continual blood shortage and anemia [2]. This situation can cause damage to multiple organ systems throughout the body, potentially resulting in fatal complications such as eye issues, gallstones, infections, joint pain and stiffness, kidney or liver issues, chronic pain, heart issues, stroke or other brain injuries, painful erections, and severe anemia [3].
Fortunately, current treatments and guidelines focus on improving life expectancy for individuals with SCA. The primary strategy involves symptom management, prevention of complications, and disease-modifying therapies, with curative options available in select cases [4].
One of the key treatments is hydroxyurea (Hydroxycarbamide), an FDA-approved disease-modifying drug for SCD. This medication increases the production of fetal hemoglobin, reducing sickling of red blood cells, leading to fewer painful crises, lower hospitalization rates, and improved survival [1][2][4].
In addition to hydroxyurea, pain management plays a crucial role in improving quality of life. Medications such as acetaminophen, ibuprofen, and opioids are used during pain crises to alleviate symptoms [1][4]. Preventive care is also essential, with routine vaccinations and folic acid supplements recommended to prevent infections and support red blood cell production [1].
Blood transfusions are another essential component of care. Long-term or episodic transfusions help treat severe anemia, prevent stroke, and reduce complications like acute chest syndrome by increasing normal red blood cell levels. Red cell exchange transfusion, a specialized form, replaces sickled cells [1][4].
Newer drugs like Voxelotor help reduce the need for transfusions by improving red blood cell function [4]. However, Crizanlizumab, once used to reduce pain crises, has been withdrawn due to effectiveness concerns as of January 2024 [4].
Curative therapies offer hope for a long-term cure. Bone marrow (stem cell) transplant remains the only proven cure for SCD, especially effective in children with severe disease when a suitable donor is available [1][4][5]. Gene therapy is an emerging approach aiming to correct the genetic mutation and offers hope for a long-term cure but is still experimental [1][5].
Guidelines emphasize early diagnosis, comprehensive preventive care, and multidisciplinary management to improve outcomes and life expectancy. Recent legislation, such as the Sickle Cell Disease Comprehensive Care Act in the U.S., is working toward better coordinated care access through Medicaid programs [3].
With proper care, most people with SCA live to adulthood, but they still face reduced life expectancy and several possible complications that can severely affect their quality of life. Current treatments and emerging therapies aim to improve symptoms and overall life expectancy, offering hope for a brighter future for those affected by SCA.
