OBJECTIVE: The objective of this study is to identify some nutritional deficiencies in thalassemic patients on regular transfusion therapy and to assess the improvement after dietetic modification.
MATERIALS AND METHODS: This cross-sectional hospital-based study was conducted in thalassemia patients admitted to the Pediatric Ward of JSS Hospital, Mysore for 6 months. Those with any concurrent illnesses that could interfere with dietary intake were excluded. Dietary data were collected by 24 h recall method. The total amount of energy, protein, fat, calcium, iron, phosphorus, fiber, and carbohydrates consumed was estimated. Dietary counseling was then done to meet the recommended daily allowance of deficient nutrients for that specific age group during the next follow-up to the hospital. Using the similar 24-h recall method, the total amount of energy, protein, fat, calcium, iron, phosphorus, fiber, and carbohydrates consumed was again estimated and assessed after 6 months.
ETHICAL CLEARANCE: Institutional Ethical Clearance was taken from the ethics committee before commencing the study. An informed written consent was taken from the parents before starting data collection.
RESULTS: Before diet counseling, the study showed that all children consuming iron deficient diet suffered from deficiencies of calories, fiber, calcium, and phosphorus. All children seemed to consume adequate levels of protein, fat, and carbohydrates. On the 6-month review, these deficiencies continued to persist, but the nutritional value of the diet seemed to show an improvement when compared to their pre-counseled values.
CONCLUSION: The emphasis on iron deficient diets in thalassemic children causes associated deficiencies. Emphasis on diet rich in these elements with follow-up dietary counseling during each visit is required to maintain a balanced nutrition.

Thalassemia is an inherited autosomal recessive disorder of hemoglobin synthesis resulting from an alteration in the globin chain production due to a defect in intron/exon splicing or missense/nonsense mutation. It can either cause a decrease in the production (thalassemia minor) or a total absence of globin chain synthesis (thalassemia major), the latter being more severe. It is diagnosed in early life when children present with anemia, hepatosplenomegaly, jaundice, and bone changes as described originally by Cooley and Lee. With transfusion therapy, they achieve adulthood but suffer its consequences of chronic iron overload. Because the body lacks any effective means for excreting excess iron, transfusion therapy results in a progressive accumulation of iron, which may be augmented by its absorption from diet as a result of increased ineffective erythropoiesis. Eventually, liver, pancreas, heart and other organs develop an extensive iron injury. The severity of toxicity seems to be related to magnitude of the body iron burden. Hence, without treatment or dietary modification, toxic levels are reached easily. Therefore, in addition to chelation therapy, they are advised iron deficient diet. How these modifications impact other nutrient intake, is not clear. The present study was geared to look at this issue.
| Materials and Methods|| |
This cross-sectional hospital-based study was conducted in thalassemia patients admitted to Pediatric Department of JSS Hospital, Mysore. The study was carried out for the duration of 6 months. Thirty children belonging to various age groups were chosen starting from 6 months to 18 years.
Institutional Ethical Committee clearance was taken before the commencement of the study. Informed written consent was obtained from one of the parents/guardians before collecting the data.
Thalassemia patients with comorbidities such as diabetes mellitus, sepsis, nephrotic syndrome, cirrhosis, and sideroblastic anemia that can modify the iron deficient diet were excluded from the study. Anthropometric measurements such as height, weight, head, and mid-arm circumferences were measured using standard methods.
Height was measured in the Pediatric Ward of JSS Hospital. A standard height chart was used and was measured in centimeters.
Weight was measured using a standard weighing scale and was measured in kilograms.
Head circumference was measured using a standard measuring tape. It was only done for children until age 5 years and was measured in centimeters.
Mid arm circumference
Mid-arm circumference was measured using a standard measuring tape. It was done for children only until the age of 5 years and was measured in centimeters.
Body mass index
Body mass index (BMI) was calculated and compared with the standard BMI chart to assess the nutritional status of the child.
Calculation of calories and other parameters
Intake of food items was measured using different sized bowls which had milliliter and ounces as their unit of measurement. If chapatis or paranthas was also included in the list then big was classified as 6 inches, and small was classified as 4 inches. This was compared to a food chart which was procured from the dietician at JSS Hospital.
The dietary data were collected by 24-h recall method. Dietary counseling with the dietician was done to ensure consumption of iron deficient diet and also to educate the child's parents/guardians about intake of food rich in other essential nutrients. The total amount of calories, protein, fat, carbohydrate, fiber, calcium, phosphorous, and iron consumed was estimated. The diet was evaluated based on the reference ranges listed in [Table 1], and the excess/deficit of nutrients consumed was estimated , After a month, when the patient came for regular follow-up, dietary data were collected employing the same 24 h recall method, and the two data were compared to check for improvement in nutritional status. Statistical analysis was not done for the study, as the statistician did not feel the need for it.
| Results|| |
Before diet counseling, it was seen that there was a deficit in calories, calcium, fiber, phosphorus in the iron deficient diet of all children, indicated by the negative values in [Table 2]. All children consumed diet with adequate levels of protein, fat and carbohydrates. After diet counseling, the deficit in calories was −397.37 as opposed to −54.34 before counseling. The deficit in calcium was seen to be −271.05, improved from −319.15 before counseling. A similar trend is seen in fiber and phosphorus levels as well. These children seemed to consume adequate levels of protein, fat, and carbohydrates.

| Discussion|| |
Iron overload is a major problem in thalassemics on transfusion therapy. To prevent iron from accumulating, these patients are advised an iron free diet and are given chelators such as deferasirox to bind to free iron and prevent toxicity.
Administration of an iron free diet also has an effect on the nutritional status of these patients. Adhering to this diet will not only decrease iron levels in the body but will also decrease levels of other essential nutrients which will be required by the body to carry out various functions. For example, avoiding spinach in the diet, not only decreases dietary iron, but also other essential nutrients such as Vitamin K, Vitamin A, calcium, potassium, Vitamin C, dietary fiber, protein, and zinc.
Nutritional deficiency is considered as a red flag for the child as it is closely linked with growth and development delay. Zinc playing an important role, whose deficiency leads to stunted growth, is highly required by thalassemic children. This deficit is seen to be more prevalent in these children. An additional zinc supplementation in their diet is thus a necessity, which ends up improving bone mineral content as well. In thalassemic children, the amounts of nutrients that need to be consumed are on a higher side when compared to a normal healthy child. This could be attributed to the continuous source of energy requiring to be supplied for effective hemoglobin and red blood cell turnover. Short stature and malnutrition are highly prevalent among these children and adolescents up to 18 years, more so malnutrition and stunted growth sets in much earlier if transfusion and chelation therapy was started at a younger age. We observed a similar trend in our study as energy and protein deficits were higher among the older age group who received transfusion therapy for a longer time.
Journal of the Academy of Nutrition and Dietetics published a paper back in January 2012, which shed light on inadequate dietary intake in thalassemic children. They found that 30% of the subjects were deficient in Vitamins A, D, E, and K along with deficiencies in micronutrients such as calcium, magnesium, and folate. Furthermore, the deficiencies and dietary inadequacy increased with an increase in age group. Our study also reflects similar findings and showed that the mean energy, phosphorus, and calcium intake were deficient when calculated among all children. Thus, from the above findings, we can conclude that to lower the burden of nutritional deficiencies in thalassemic children it is important to address the issue as early as possible and tackle it by ensuring adequate diet counseling along with appropriate nutritional supplementation.
On the initial assessment of the diet, it was found that thalassemic children were deficient in most of the nutrients and minerals required for healthy growth and development. These included calcium, calories, fiber, and phosphorus. Diet counseling was provided for these patients when they came for regular follow-up/blood transfusions. The diet counseling done was to attempt to increase essential nutrients intake as well as to keep the iron levels low.
On comparing the data before and after the intervention, it was found that there was an improvement in the nutritional status of the patients, but the required daily allowance was not met. The mean calorie intake was however found to be more prominent before and after counseling, showing the need for continuous dietary monitoring. Dietetic manipulation may, therefore, be inadequate to correct nutritional deficiencies in this population. The importance of nutritional assessment and correction of deficiencies with appropriate supplementation may, therefore, be a requirement in these children.
| Conclusion|| |
Emphasis on iron restriction normally dominates diet counseling in thalassemic children. It is possible that other nutrients become deficient in this process. The present study demonstrated a lack of attainment of required nutrients by the thalassemic children and the need for continuous dietary assessment and counseling to attain a balanced nutrition.
