Hemolysis, Pulmonary Hypertension, Thalassemia in Children
Conditions
Keywords
Thalassemia, Glutamine/glutamate ratio, Pulmonary hypertension
Brief summary
The study will investigate the relation between erythrocyte glutamine/glutamate ratio and pulmonary hypertension risk in Egyptian thalassemic children in Assiut University Children Hospital
Interventions
blood sample for measuring liver and kidney function, CBC, ferritin level and erythrocyte glutamine level
Tricuspid regurge velocity will be measured by doppler echocardiography denoting the pulmonary hypertension risk in children

Eligibility
Inclusion criteria
* Established diagnosis of Thalassemia. * PH risk documented by doppler echocardiography, defined as tricuspid regurge velocity (TRV) equal to or greater than 2.5 m/s
Exclusion criteria
* Acute crisis or hospitalization within 1 month of enrollment * Hepatic dysfunction (SGPT greater than 3X normal) * Renal dysfunction (Creatinine greater than 2X normal) * Patients on sildenafil (Viagra), calcium channel blockers or other drugs for the control of PH.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
