Diagnosis, Treatment and Prevention of Nutritional Anemia in Children: Recommendations of the Joint Committee of Pediatric Hematology-Oncology Chapter and Pediatric and Adolescent Nutrition Society of the Indian Academy of Pediatrics.

JUSTIFICATION: Anemia in children is a significant public health problem in our country. Comprehensive National Nutrition Survey 2016-18 provides evidence that more than 50% of childhood anemia is due to an underlying nutritional deficiency. The National Family Health Survey-5 has reported an increase in the prevalence of anemia in the under-five age group from 59% to 67.1% over the last 5 years. Clearly, the existing public health programs to decrease the prevalence of anemia have not shown the desired results. Hence, there is a need to develop nationally acceptable guidelines for the diagnosis, treatment and prevention of nutritional anemia. OBJECTIVE: To review the available literature and collate evidence-based observations to formulate guidelines for diagnosis, treatment and prevention of nutritional anemia in children. PROCESS: These guidelines have been developed by the experts from the Pediatric Hematology-Oncology Chapter and the Pediatric and Adolescent Nutrition (PAN) Society of the Indian Academy of Pediatrics (IAP). Key areas were identified as: epidemiology, nomenclature and definitions, etiology and diagnosis of iron deficiency anemia (IDA), treatment of IDA, etiology and diagnosis of vitamin B12 and/or folic acid deficiency, treatment of vitamin B12 and/or folic acid deficiency anemia and prevention of nutritional anemia. Each of these key areas were reviewed by at least 2 to 3 experts. Four virtual meetings were held in November, 2021 and all the key issues were deliberated upon. Based on review and inputs received during meetings, draft recommendations were prepared. After this, a writing group was constituted which prepared the draft guidelines. The draft was circulated and approved by all the expert group members. RECOMMENDATIONS: We recommend use of World Health Organization (WHO) cut-off hemoglobin levels to define anemia in children and adolescents. Most cases suspected to have IDA can be started on treatment based on a compatible history, physical examination and hemogram report. Serum ferritin assay is recommended for the confirmation of the diagnosis of IDA. Most cases of IDA can be managed with oral iron therapy using 2-3 mg/kg elemental iron daily. The presence of macro-ovalocytes and hypersegmented neutrophils, along with an elevated mean corpuscular volume (MCV), should raise the suspicion of underlying vitamin B12 (cobalamin) or folic acid deficiency. Estimation of serum vitamin B12 and folate level are advisable in children with macrocytic anemia prior to starting treatment. When serum vitamin B12 and folate levels are unavailable, patients should be treated using both drugs. Vitamin B12 should preferably be started 10-14 days ahead of oral folic acid to avoid precipitating neurological symptoms. Children with macrocytic anemia in whom a quick response to treatment is required, such as those with pancytopenia, severe anemia, developmental delay and infantile tremor syndrome, should be managed using parenteral vitamin B12. Children with vitamin B12 deficiency having mild or moderate anemia may be managed using oral vitamin B12 preparations. After completing therapy for nutritional anemia, all infants and children should be advised to continue prophylactic iron-folic acid (IFA) supplementation as prescribed under Anemia Mukt Bharat guidelines. For prevention of anemia, in addition to age-appropriate IFA prophylaxis, routine screening of infants for anemia at 9 months during immunization visit is recommended.

Prevention of Micronutrient Deficiencies in Young Children: Consensus Statement from Infant and Young Child Feeding Chapter of Indian Academy of Pediatrics.

JUSTIFICATION: Micronutrient deficiencies have significant impact on the overall health and well-being of society and potential targets for supplementations. It is important to formulate a consensus statement in view of current evidence, and put in place strategies to meet targets. OBJECTIVE: To formulate by endorsement or adoption and disseminate a consensus statement for prevention of micronutrients deficiencies in young children for office practices from an Indian perspective. PROCESS: A National Consultative Meeting was convened by Infant and Young Child Feeding Chapter (IYCF) of Indian Academy of Pediatrics (IAP) on 17 December, 2016 at Mumbai. IYCF chapter, IAP, United Nations Children Fund, National Institute of Nutrition and Government of India were the participating agencies; and participants representing different parts of India were included. CONCLUSIONS: Micronutrient deficiencies are widespread. For its prevention proper maternal and infant-young child feeding strategies need to be practiced. Encourage delayed cord clamping, dietary diversification, germinated foods, soaking and fermentation processes. Existing Iron, Vitamin A, Zinc supplementation and universal salt iodization programs need to be scaled up, especially in high risk groups. Universal vitamin D supplementation need to be in place; though, the dose needs more research. Vitamin B12 deficiency screening and supplementation should be practiced only in high-risk groups. Availability of appropriately fortified foods needs to be addressed urgently.

Folate, vitamin B12, homocysteine and polymorphisms in folate metabolizing genes in children with congenital heart disease and their mothers.

BACKGROUND/OBJECTIVES: The objective of the study was to assess the role of variations in serum folate, vitamin B12, homocysteine and the presence of genetic polymorphisms as risk factors for congenital heart disease (CHD) in children. SUBJECTS/METHODS: A total of 32 children with CHD, and their mothers and 32 normal children and their mothers formed the study and control groups, respectively. Serum folate, vitamin B12 and homocysteine as well as genetic polymorphisms MTHFR C677→︀T, MTHFR A1298→︀C, MTR A2756→︀G and MTRR A66→︀G were assessed. RESULTS: Low serum folate and genetic polymorphisms MTHFR C677→︀T and MTRR A66→︀G among children and their mothers and high homocysteine among mothers were noted as risk factors for CHD (P<0.05). Vitamin B12 levels were normal and showed no association. Presence of MTHFR C677→︀T and MTRR A66→︀G, both concurrently among children as well as mothers and simultaneously among mother-child pairs, showed several fold increase in the risk for CHD. On multivariate analysis, the risk factors noted for CHD were presence of MTHFR C677→︀T among children and their mothers and MTRR A66→︀G among mothers. Analyses for nutrient-gene interaction revealed significant associations between low serum folate and high serum homocysteine levels, and the presence of selected genetic polymorphisms. CONCLUSIONS: Low serum folate, high homocysteine and presence of selected genetic polymorphisms among children and their mothers were noted as risk factors for CHD. Nutrient-gene interaction being a modifiable risk factor, the study recommends the use of peri-conceptional folate supplementation with vitamin B12 sufficiency for primary prevention of CHD.

Crusade against Malnutrition: Nutrition Education Program.

A holistic approach in assessment and plan for intervention in childhood malnutrition is the need of the hour. This is in the context of nutrition education program (NEP), undertaken under the National IAP action plan, 2015. In the crusade against malnutrition, an ABCDEFQ assessment scale is recommended, with aspects covering anthropometric, biochemical, clinical, dietary, ecological/epidemiological, functional parameters and quality of life. In the dietary assessment, a scoring system based on the ten interventions related to infant and young child feeding (IYCF) practices recommended by UNICEF and the food frequency table score are incorporated. In the evaluation of quality of life and plan for intervention, a tool called IMPACT (IAP Malnutrition Proactive Assessment: A Comprehensive Tool) is proposed.

Umbilical cord blood nutrients in low birth weight babies in relation to birth weight & gestational age.

BACKGROUND & OBJECTIVE: Low birth weight (LBW) babies are a vulnerable group and represent two outcomes--preterm birth (preterm LBW) and term with intrauterine growth retardation (term LBW). LBW babies are considered to have low nutrient reserve, but the extent of deficiency as compared to the normal babies and the differences between preterm LBW and term LBW are unclear. This study was carried out to look at key anthropometric, biochemical and clinical (ABC) parameters of LBW babies, both preterm and term, in comparison to a control group of term normal weight babies. METHODS: A group of 500 babies was selected at birth from a tertiary care teaching hospital and categorized into LBW (n = 251) with preterm LBW (n = 59), term LBW (n = 192) and term controls (n = 249). Two controls were dropped as tests could not be performed in the available cord blood sample. Key anthropometric and biochemical parameters were measured. Socio-economic status, age, parity, height and pre-delivery haemoglobin of the mothers were also recorded. RESULTS: The maternal characteristics were comparable in the three groups. Socio-economically, majority of them belonged to lower middle or upper lower class (Class III and IV) representing the non affluent. All the anthropometric measurements and nutrients measured namely total protein, albumin, cholesterol, triglycerides, calcium, magnesium, zinc and iron were significantly lower in LBW babies compared to term control babies. These values were lowest in preterm LBW followed by term LBW. Total iron binding capacity (TIBC) showed inverse association with iron. Some of the babies including control babies had protein, albumin, calcium and iron below the normal range and mean albumin, calcium and iron levels were below the normal range in all the three subsets. INTERPRETATION & CONCLUSION: Preterm and term LBW babies are born with significantly lower nutrient reserves at birth compared to term control babies. Normal weight babies from the non affluent sections also have low nutrients especially albumin, calcium and iron. As these levels are liable to be further lowered by recurrent infections and inappropriate feeding habits, nutritional surveillance, extra feeding and supplements like calcium and iron are recommended for such vulnerable babies to promote optimum growth and to prevent deficiencies. This is important as currently, there are no clear or uniform recommendations for extra feeding and nutrient supplements to LBW babies and no supplements other than exclusive breast feeding are recommended for term normal birth weight babies. Extra nutritional inputs for LBW and selected non affluent babies along with care of the prospective and prenatal mothers for ensuring adequate transfer of nutrients to the offspring seem necessary. Such interventions can be integrated with the existing health care programmes to reach all the beneficiaries.

Auxologic, biochemical and clinical (ABC) profile of low birth weight babies- a 2-year prospective study.

INTRODUCTION: Low Birth Weight (LBW) is a key determinant of neonatal mortality, morbidity, subsequent growth and development as well as early onset of adulthood diseases. It represents a conflation of two outcomes-preterm- and term 'light for date' (LFD) babies. This study looks at key auxologic, biochemical and clinical (ABC) parameters of a cohort of LBW babies, both preterm- and term in comparison to a group of normal-term (control) babies. An attempt was also made to see how these parameters were at the end of a 2 year follow-up period with the currently available interventions. MATERIALS AND METHODS: A cohort of 500 babies was selected at birth from a tertiary care teaching hospital in Kerala, India, key ABC indices were measured including relevant maternal data. The initial biochemical measurements were done using umbilical cord blood. Currently recommended nutritional interventions were provided to all the normal and LBW babies. At the end of 2 years, the measurements were repeated in a subset of babies available for follow-up (n = 147). RESULTS: From the cohort of 500 babies, two had to be eliminated as biochemical parameters could not be done due to technical reasons from the available umbilical cord blood. They were categorized into three groups: preterm-LBW (11.85%), term-LBW (38.55%) and normal-term controls (49.6%). The maternal characteristics like socio-economic status, maternal weight, height, BMI and hemoglobin levels were comparable in the three subsets. All of them belonged to middle or low-socio-economic status representing the non-affluent. In the initial group (n = 498), all the auxologic measurements and the nutrients measured namely, total protein, albumin, total cholesterol, triglycerides, calcium, magnesium, zinc and iron levels were significantly lower (p < 0.05) among LBW, lowest in preterm followed by term-LBW, compared to term controls. Total iron binding capacity showed inverse correlation with iron level. Protein, albumin, calcium and iron levels were low in many babies, and mean calcium and iron levels were below the normal range in all the three subsets reflecting reduced transfer from the mother. At the end of 2 years, calcium, magnesium, zinc and iron were significantly lower in preterm- and term-LBW (p < 0.05) compared to controls and mean value of serum calcium continued to be below the normal range in all the three subsets. At final follow-up, majority of the LBW babies had varying grades of malnutrition and only 1 (7%) of preterm-LBW subset and 13 (28%) of term-LBW subset had optimum catch up growth resulting in normal nutritional status with the existing interventions. Three (3.5%) of the normal babies were noted to slip down to malnutrition at the end of 2 years. CONCLUSIONS: Preterm- and term-LBW babies are born with significantly lower nutrient reserves at birth compared to term-normal babies, this was lowest among the preterm babies. As this reserve may be further lowered by recurrent infections and inappropriate feeding habits, there is a need for special feeding and nutrient supplements in this group. Calcium and iron levels were suboptimum at birth and calcium levels remained suboptimum even at the end of 2 years in all three subsets including controls in this non-affluent group. Currently available interventions may prevent the occurrence of overt clinical nutrient deficiencies, but do not ensure optimum growth, even among normal birth weight babies as some of these babies were seen to slip into the pool of malnutrition subsequently. Specialized nutritional surveillance and supplements are recommended for LBW babies to promote optimum growth and prevent subclinical nutrient deficiencies. Infant feeding practices should be strengthened and integrated with the existing health care programs to reach all the beneficiaries. Along with the existing special supplementation programs like iron folic acid, vitamin A, iodine etc., calcium supplementation should also be considered. It is also essential to concentrate on the girl child, the adolescent girl, prospective mother and prenatal mother to ensure optimum nutrition and nutrient transfer to future offsprings.
