Study Design Observational Model: Cohort
Time Perspective: Cross-Sectional
Target Follow-Up Duration Not Provided
Biospecimen Retention:   Samples Without DNA
Description:
Plasma sample
Sampling Method Probability Sample
Study Population Upper Egypt thalassemic children aged 10-18 years old attending Assiut University Children Hospital.
Condition
  • Thalassemia in Children
  • Pulmonary Hypertension
  • Hemolysis
Intervention
  • Diagnostic Test: blood sample
    blood sample for measuring liver and kidney function, CBC, ferritin level and erythrocyte glutamine level
  • Diagnostic Test: Tricuspid regurge velocity
    Tricuspid regurge velocity will be measured by doppler echocardiography denoting the pulmonary hypertension risk in children
Study Groups/Cohorts
  • on chelation

    patients with B-thalassemia major samples of which will be examined for renal and liver function, Erythrocyte Glutamine level, ferritin level and complete blood picture. Also Echo will be done for measuring the Tricuspid regurge velocity.

    group 1: cases on chelation: deferasirox 500mg oral tablet with initial dose 20 mg/kg guided by ferritin level

    Diagnostic Test: blood sample

    Diagnostic Test: Tricuspid regurge velocity

    Interventions:
    • Diagnostic Test: blood sample
    • Diagnostic Test: Tricuspid regurge velocity
  • No chelation

    group 2: cases without chelation

    Diagnostic Test: blood sample

    Diagnostic Test: Tricuspid regurge velocity

    Interventions:
    • Diagnostic Test: blood sample
    • Diagnostic Test: Tricuspid regurge velocity
  • splenectomy

    group 3: cases with splenectomy

    Diagnostic Test: Tricuspid regurge velocity

    Interventions:
    • Diagnostic Test: blood sample
    • Diagnostic Test: Tricuspid regurge velocity
  • no splenectomy
    group 4: cases without splenectomy Diagnostic Test: blood sample Diagnostic Test: Tricuspid regurge velocity
    Interventions:
