Evaluation of Nutritional Status in Thalassemia Major Patients in Assiut Children Hospital

Thalassemia Major

thalassemia - nutrition -growth

Thalassemia is a blood disorder passed down through families in which the body makes an abnormal form of hemoglobin. There are 2 main types of thalassemia; Alpha & Beta thalassemia. Alpha thalassemia: occurs when a gene or genes related to the alpha globin protein are missing or mutated. Beta-thalassemia syndromes are a group of hereditary blood disorders characterized by reduced or absent beta globin chain synthesis. Beta-thalassemias can be classified into: Silent carrier: completely asymptomatic with normal hematological parameters. Beta-thalassaemia minor (beta-thalassaemia trait): usually asymptomatic; diagnosis is made during a work-up for mild anemia. Beta-thalassaemia intermedia: usually a similar presentation to beta-thalassaemia major; symptoms are usually less pronounced and the course is usually more insidious. Beta-thalassaemia major : In which there is complete absence of hemoglobin A

In Egypt beta thalassemia-major is the most common type with carrier rate of 5.3 to ≥9%and 1000 new cases born with beta-thalassemia major per 1.5 million live births per year. Children born with thalassemia major are normal at birth, but develop severe hemolytic anemia during the first year of life. Symptoms are those of anemia (lethargy, poor feeding, pallor…etc.) failure to thrive and organomegaly. Later on they develop signs of extra medullary hematopoiesis . Optimal nutritional status is important for growth, immune function, bone health and pubertal development . Various reports suggest the incidence of poor growth ranges from 25% to 75% depending on thalassemia syndrome and severity of disease. This marked growth deficits raise a red flag for any pediatrician to evaluate nutritional status of thalassemic patients and detect possible nutritional deficiencies and associated factors. Etiology of delayed growth and malnutrition reported in thalassemic patient is multifactorial including : 1. Nutritional deprivation with or without feeding difficulties arising from fatigue and breathlessness 2. Increased energy expenditure secondary to hyper metabolism with or without heart failure 3. Gastrointestinal hypoxia which consequently produces anorexia and malabsorption 4. Reduction of biosynthetic activity of liver. 5. Disturbance of the endocrine function 6. Impaired synthetic hepatic function secondary to hemosiderosis and hepatitis. The main aim of this study is to assess the nutritional status of thalassemic patient attending Assiut university Children hospital and to determine the factors involved.
