Relationship between tocopherols and serum lipid levels in children with beta-thalassemia major
Insights
Children with beta-thalassemia major often have low serum tocopherol (vitamin E) levels, especially with inadequate blood transfusions. This study highlights the importance of monitoring vitamin E in these patients.
Area of Science:
- Hematology
- Nutritional Science
- Pediatrics
Background:
- Beta-thalassemia major is a severe inherited blood disorder.
- Inadequate treatment can lead to various complications.
- Vitamin E (tocopherol) plays a crucial role in cellular protection.
Purpose of the Study:
- To investigate serum tocopherol levels in children with beta-thalassemia major.
- To compare tocopherol levels with serum total lipids in these patients.
- To assess potential vitamin E deficiency in beta-thalassemia major.
Main Methods:
- Measured serum tocopherol and total lipid levels in 18 children with beta-thalassemia major.
- Compared levels with those of healthy controls.
- Calculated the ratio of serum tocopherol to total lipids.
Main Results:
- 50% of children had below-normal serum tocopherol levels.
- Mean tocopherol and total lipid levels were significantly lower in beta-thalassemia patients compared to controls.
- The ratio of tocopherol to lipids was also significantly lower in patients.
Conclusions:
- Children with beta-thalassemia major exhibit reduced serum tocopherol and total lipid levels.
- Lower tocopherol-to-lipid ratios suggest potential vitamin E insufficiency.
- Monitoring vitamin E status is crucial for managing beta-thalassemia major.
Abstract:
Serum tocopherol levels were found to be below normal (less than 0.5 mg/100 ml) in nine (50%) of 18 children with beta-thalassemia major receiving inadequate treatment with blood transfusions. The mean tocopherol levels were significantly lower in the children with beta-thalassemia (0.57 mg/100/ml +/- 0.20) than in the controls (1.08 mg/100 ml +/- 0.24). Serum total lipid levels were found to be low in children with beta-thalassemia. The difference between the mean total lipid level in the beta-thalassemic patients (365 mg/100 ml +/- 75) as compared to that of the controls (581 mg/100 ml +/- 94) was highly significant (P less than 0.01). The ratio of serum tocopherol to 1 g total lipids was lower in children with beta-thalassemia (1.41 mg/100 ml +/- 0.43) than in the controls (1.88 mg/100 ml +/- 0.46) and the difference was significant. Yet, only three out of the 18 children with beta-thalassemia showed a ratio of less than 0.8 mg/100 ml tocopherol per 1 g total lipid which may be considered indicative of tocopherol deficiency.
