Sickle Cell Trait: Symptoms, Potential Health Issues, Diagnostic Procedures, and Further Details
In a call for greater awareness and emphasis on screening, genetic counseling, and research, it's essential to understand the differences between sickle cell disease (SCD) and sickle cell trait (SCT). While SCD is a more severe condition with chronic and severe complications, SCT is a genetic trait that, while generally asymptomatic, may increase the risk of certain complications under specific conditions.
SCT is caused by inheriting one atypical hemoglobin gene and one normal gene, unlike SCD, which results from inheriting two sickle cell genes. Most people with SCT have no medical issues as a result, but complications can occur in rare cases. These complications, known as exertional complications, include an increased risk of muscle breakdown, heatstroke, and sudden exertional collapse during extreme physical stress, dehydration, or high altitude exposure.
Individuals with SCT may also experience splenic infarction, or tissue death due to blocked blood flow, at high altitudes, and hematuria, or blood in the urine, due to sickling in the renal medulla where oxygen tension is low. It's crucial for those with SCT to avoid extreme dehydration, maintain adequate hydration, especially during intense exercise or heat exposure, and be cautious when exposed to high altitudes, as oxygen levels are lower and can provoke sickling complications.
Precautions for individuals with SCT also include informing healthcare providers of SCT status, especially before surgery, anesthesia, or participation in intense physical activities, and monitoring for unusual symptoms such as unexplained pain or hematuria and seeking medical attention if they arise. Regular medical follow-up is generally not required unless symptoms develop.
It's important to note that the comprehensive complications mentioned, such as chronic anemia, organ damage, frequent infections, and more, are typically associated with SCD, not SCT. SCD patients suffer from these severe complications, while SCT carriers do not usually experience them.
In the United States, SCT is most common among African Americans, affecting 8-10% of these individuals. While most experts consider SCT to be benign, there is some debate about the rates of various complications. If both biological parents have SCT, they may have a child with SCD, and if only one parent has SCT, they have a 50% chance of passing the trait to their child.
If you know you have SCT, it's recommended to speak with a genetic counselor before having children. In the U.S., it is routine to test all newborns for SCT, and approximately 1 out of every 365 Black or African American births results in sickle cell disorder.
The lack of funding for SCT and SCD stems from inequity in healthcare, a problem that health experts state needs urgent addressing. More funding is necessary for research and awareness of SCD worldwide, as funding in the U.S. for this area of health is less than for conditions that affect fewer people, such as cystic fibrosis.
