Sickle Cell Genetic

Sickle Cell Disease (SCD) is a group of inherited red blood cell disorders characterized by abnormal hemoglobin (HbS). This mutation causes red blood cells to become rigid, sticky, and crescent-shaped, leading to vaso-occlusive crises, chronic anemia, and systemic organ damage.

SCD is caused by a point mutation in the HBB gene on chromosome 11, resulting in the substitution of valine for glutamic acid at the sixth position of the beta-globin chain. It is inherited in an autosomal recessive pattern.

Under low-oxygen conditions, HbS polymerizes, distorting the erythrocyte membrane. These "sickled" cells occlude microvasculature, causing tissue ischemia and infarction. Chronic hemolysis leads to systemic inflammation and endothelial dysfunction.

Most prevalent in populations of sub-Saharan African, Mediterranean, Middle Eastern, and Indian descent. In the U.S., it affects approximately 100,000 individuals, predominantly those of African ancestry.

Inheritance of two abnormal hemoglobin genes (SS, SC, or S-beta thalassemia), dehydration, extreme temperatures, infection, and physical/emotional stress.

A. Early Symptoms: Jaundice, dactylitis (hand-foot syndrome), failure to thrive.
B. Common Symptoms: Chronic anemia, joint/bone pain, fatigue, delayed puberty.
C. Advanced Symptoms: Leg ulcers, retinopathy, gallstones, avascular necrosis.
D. Emergency Symptoms: Acute chest syndrome, stroke, priapism, splenic sequestration.

Pallor, scleral icterus, splenomegaly (in children), systolic murmurs (flow murmur), and tenderness over bony prominences.

A. Clinical Assessment: History of pain episodes.
B. Laboratory Testing: CBC, reticulocyte count, hemoglobin electrophoresis.
C. Imaging Studies: Doppler ultrasound for stroke risk.
D. Functional Tests: Pulse oximetry.
E. Biopsy Findings: N/A.
F. Genetic Testing: DNA analysis for HBB mutations.
G. Differential Diagnosis: Thalassemia, hereditary spherocytosis, G6PD deficiency.

Hemoglobin Electrophoresis
Type: Blood Test
Purpose: Identify hemoglobin variants.
Expected Findings: Presence of HbS.
Interpretation: Diagnostic for SCD.

Transcranial Doppler (TCD): Screens for stroke risk in children by measuring blood flow velocity in the brain.
Chest X-ray: Essential to identify infiltrates in Acute Chest Syndrome.

Thalassemia major, iron deficiency anemia, and other hemoglobinopathies like Hemoglobin C or E.

Acute chest syndrome, stroke, organ failure (kidney, liver), and blindness.

A. Lifestyle Modifications: Hydration, avoiding temperature extremes.
B. Preventive Measures: Vaccination, prophylactic penicillin.
C. Medical Treatment: Hydroxyurea (induces HbF), Voxelotor, Crizanlizumab.
D. Surgical Treatment: Splenectomy, hip replacement for necrosis.
E. Interventional Procedures: Blood transfusions (exchange transfusion).
F. Rehabilitation: Pain management, physical therapy.
G. Emergency Management: Oxygen, IV fluids, analgesia, antibiotics.

With modern medical management (vaccinations and hydroxyurea), life expectancy has improved significantly, with many patients surviving into their 50s and beyond.
