Is Iron Supplementation Influenced by Sub-Clinical Inflammation?: A Randomized Controlled Trial Among Adolescent Schoolgirls in Myanmar.

Iron absorption was impaired in the presence of sub-clinical inflammation (SCI) and might hamper the effect of iron supplementation. The purpose of the study was to identify the influence of SCI on iron supplementation. A randomized, double-blinded, placebo-controlled experimental study was conducted among anaemic adolescent schoolgirls in Ayeyarwady region, Myanmar. A total of 402 schoolgirls were recruited from six schools screened from 1269 girls who were assigned into one of four groups: Folate group (2.5 mg of folate), Vitamin A group (15,000 IU of vitamin), Iron folate group (60 mg elemental iron and folate) and Iron, and vitamin A and folate group. Supplementation was done once a week for 12 weeks. Iron, vitamin A and inflammation were measured at the baseline, middle and endline. Changes in serum ferritin and body iron were significantly higher in the IFA and IFA + vitA among those without SCI. There was interaction between vitamin A and SCI on Hb changes. Analysis of GLM repeated measure showed interactions between treatment and SCI for hemoglobin and serum transferrin receptor. Those treated with vitamin A had better outcomes when there was SCI. Inflammation accompanied a negative effect on iron supplementation and vitamin A improved efficacy of iron supplementation in the presence of SCI.

Pneumococcal vaccination for splenectomized patients with thalassemia major in Indonesia.

INTRODUCTION: Streptococcus pneumoniae is a capsulated bacterium that can cause severe infection in patients with thalassemia major, particularly those who have undergone splenectomy. The absence of the spleen as well as zinc deficiency in splenectomized patients with thalassemia major increases the possibility of developing invasive pneumococcal infection. The aims of this study are to evaluate pneumococcal IgG levels following PCV and PPV immunizations and the effect of zinc supplementation on qualitative specific immune responses in splenectomized patients with thalassemia. METHODS: Splenectomized patients with thalassemia major were administered a PCV pneumococcal vaccine (Prevenar 13®) at the start of the trial, after which they were randomly assigned to 2 groups (zinc and placebo group). After 8weeks, the patients received a PPV pneumococcal vaccine (Pneumovax®). Zinc syrup was provided to the zinc group at a dose of 1.5mg/kg/day (maximum of 50mg/day). Pneumococcal IgG examinations were conducted at the start of the trial and after 12weeks. RESULTS: In the group without PPV, the median initial pneumococcal IgG value was 315 (ranging from 65 to 1419) mU/mL for the zinc group and 338.5 (ranging from 82 to 1648) mU/mL for the placebo group. The median final pneumococcal IgG value was 1812.5 (ranging from 834 to 2444) mU/mL for the zinc group and 2857.5 (ranging from 834 to 2624) for the placebo group. The increase in the pneumococcal IgG value between the two groups was comparable (p=0.642). In the group with previous PPV, the median initial pneumococcal IgG value was 1333 (ranging from 793 to 2031) mU/mL for the zinc group and 880 (ranging from 74 to 1686) mU/mL for the placebo group. The median final pneumococcal IgG value was 1487 (ranging from 635 to 1757) mU/mL for the zinc group and 1012 (ranging from 292 to 1732) mU/mL for the placebo group. The increase in the pneumococcal IgG value between the two groups was comparable (p=0.528). CONCLUSION: There is no difference in the increase in pneumococcal IgG level in splenectomized patients with thalassemia major prior to and after receiving PPV. There were no differences observed in the development of pneumococcal IgG following zinc supplementation.

Folate and vitamin B12 status and dietary intake of anaemic adolescent schoolgirls in the delta region of Myanmar.

The aim of the present study was to assess the prevalence of deficiency of folate and vitamin B12 and, simultaneously, the nutrient intake adequacy of folate, vitamin B12, iron, vitamin A, vitamin C, vitamin B6 and calcium in 391 adolescent anaemic (Hb<120 g/l) schoolgirls living in the delta region of Myanmar (Burma). Dietary intakes were assessed using a 3 d estimated food record. The distribution of observed intakes calculated from the food records were adjusted for usual intakes, and the prevalence of inadequacy was estimated using the estimated average requirement cut-point method. Median (first, third quartile) serum folate and vitamin B12 concentrations were 6·5 (4·6, 8·5) nmol/l and 612·8 (443·2, 795·2) pmol/l, respectively. The prevalence of folate deficiency defined as <6·8 nmol/l was 54 %; however, vitamin B12 deficiency defined as <148 pmol/l was negligible (<1 %). The prevalence of inadequate intake of folate was high (100 %) as was the prevalence of inadequate intakes of vitamin A, vitamin C, vitamin B6 and calcium, ranging from 60 to 100 %. Red meat or poultry was rarely consumed, but fish was consumed on a daily basis. Green leafy vegetables were also consumed frequently but consumption of dairy products was uncommon. Folate deficiency was high, and the prevalence of inadequate intake of folate among other key micronutrients was relatively common in this sample of anaemic adolescent schoolgirls. Appropriate strategies such as food fortification and dietary diversification are needed to improve the micronutrient status of these young women to ensure optimal health and future reproductive success.

Immune response of thalassemia major patients in Indonesia with and without splenectomy.

AIM: to describe non-spesific and specific immune response profile in Indonesian thalassemia major with and without splenectomy. METHODS: this study was held at Thalassaemia Centre, Cipto Mangunkusumo Hospital Jakarta on September 2013-February 2014. A comparative cross sectional study was conducted in healthy, thalassemia major aged more than 12 year and seronegative HIV. They were matched in age and sex for splenectomised and non-splenectomised groups, analysing the non-spesific immune response (neutrophil count and phagocytosis) and specific immune response (count and function of cellular immunity). Infection episodes were also analized as immune response in vivo parameter. RESULTS: splenectomised thalassemia major showed increased neutrophil count but significantly decreased non-spesific immune response (neutrophil phagocytosis). Spesific immune response of splenectomised group presented significantly higher absolute lymphocyte, lymphocyte T, CD4+ and CD8+ counts compared to non-splenectomised thalassemia major (p<0.05). Ratio CD4+/CD8+ were similar in these groups. Serum marker of activated cellular imunity function (IL-2 and TNF-) were similar among two groups. Mild infection episodes on splenectomised and non-splenectomised group were 2.02 (ranged 0 to 12) times and 0.81 (ranged 0 to 8) times (p=0.004), respectively. Severe infection on splenectomised group were sepsis for 2 weeks and diarrhea for 1 week, whereas on non-splenectomised group was typhoid fever for 4 days. CONCLUSION: there were significant differences on immune response among thalassemia major patients. Splenectomised thalassemia major showed a greater degree of susceptibility to infections than non-splenectomised thalassemia major.

The influence of vitamin A status on iron-deficiency anaemia in anaemic adolescent schoolgirls in Myanmar.

OBJECTIVE: The present study was conducted to investigate reasons for the high prevalence of anaemia among adolescent schoolgirls and to elucidate the role of vitamin A in contributing to Fe-deficiency anaemia (IDA). DESIGN: Among 1269 schoolgirls who were previously screened for anaemia (Hb < 120 g/l), 391 anaemic girls were further assessed for Fe, vitamin A and subclinical inflammation status. Fe and vitamin A indicators were corrected for inflammation and were compared in the Fe-deficient and non-deficient groups as well as between those with and without inflammation. Logistic regression was done to determine whether vitamin A status and subclinical inflammation were risk factors for Fe deficiency. The differences in Fe status among tertiles of vitamin A concentrations were assessed using ANOVA. SETTING: Myanmar. SUBJECTS: Adolescent schoolgirls (n 391). RESULTS: One-third of the anaemia (30·4%) was IDA. Prevalence of low vitamin A status (serum retinol <1·05 µmol/l) was 31·5%. Fe and vitamin A status were significantly different between the IDA and non-IDA groups and also based on their inflammation status. Logistic regression showed that low vitamin A status was a significant predictor for being Fe deficient (OR = 1·81; 95% CI 1·03, 3·19 and OR = 2·31; 1·31, 4·07 in the middle (1·056-1·298 µmol/l) and low (≤1·056 µmol/l) vitamin A tertiles, respectively). ANOVA showed that better Fe status was associated with a higher concentration of serum retinol but only in IDA. CONCLUSIONS: Fe deficiency was not the main cause of anaemia in the present population. The role of vitamin A as well as other micronutrients should be taken into account in addressing the problem of anaemia.

Microcytic anaemia predominates in adolescent school girls in the delta region of Myanmar.

OBJECTIVE: Anaemia is one of major nutritional problems in Myanmar affecting all age groups. However, there is lack of recent information and a study was conducted to acquire information on the current status of anaemia among adolescent schoolgirls in Nyaung Done township, Ayeyarwady division where an intervention study was planned. SUBJECTS AND METHODS: A cross-sectional survey was conducted on 1269 subjects to obtain complete blood count, anthropometry and socioeconomic characteristics were obtained by questionnaire. Using red cell indices, we applied Bessman's, and Green and King's index classification to differentiate the types of anaemia. Electrophoresis was also done on a subsample (n=228). RESULTS: Stunting was 21.2% and wasting was 10.7% respectively. Prevalence of anaemia was 59.1% and was mainly microcytic. Green and King's index showed 35.8% were iron deficient. Electrophoresis revealed 36 cases of Hb E haemoglobinopathy in the subsample. CONCLUSION: Anaemia is still a major nutrition problem in Myanmar. The reasons for this high prevalence should be explored and properly addressed. The study highlights the need for a comprehensive and large scale survey for the anaemia control programme in Myanmar.
