Sickle Cell S Lepore Disease C6012303

Published: July 22, 2026Updated: August 20, 2026

A blood disorder combining features of sickle cell and a rare hemoglobin variant, causing abnormal red blood cells that can block vessels. It leads to anemia, pain crises, and organ damage. Management includes transfusions and medications to reduce complications.

Diagnosis and tests

How this condition is diagnosed and what test results mean.

Initial screening tests

1

Standard diagnostic workup

Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]

Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]

Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

Evidence-based pharmacological treatment

Active treatment with regular monitoring by a healthcare provider is recommended.

medication
2

Hydroxyurea therapy

Hydroxyurea increases fetal hemoglobin production, reducing sickle cell formation and decreasing the frequency of painful crises. Regular blood count monitoring is required during treatment to assess response and adjust management.

medication
3

Exchange blood transfusion

Automated red blood cell exchange replaces sickled cells with healthy donor cells, reducing hemoglobin S levels below 30%. This is particularly beneficial during acute crises or for stroke prevention in high-risk patients.

procedure

Additional treatment options

Hydration and temperature management

Maintaining adequate fluid intake of 2-3 liters daily helps prevent blood viscosity and sickling episodes. Avoiding extreme temperatures and sudden temperature changes reduces vaso-occlusive crisis risk.

lifestyle

Folic acid supplementation

Daily folic acid supplementation of 1mg supports increased erythropoiesis demand in sickle cell patients. This helps maintain adequate red blood cell production and prevents megaloblastic anemia development.

dietary

Transcranial Doppler screening

Annual transcranial Doppler ultrasound screening detects elevated cerebral blood flow velocities indicating stroke risk in children aged 2-16. Early identification allows for intervention before neurological damage occurs.

monitoring

When to seek medical help

Recognize when you need immediate medical attention.

See a doctor within 24 hours

Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.

Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
