Clinico-Etiopathogenesis of Vitamin B12, Folic Acid and Iron Deficiency in Severe Acute Malnutrition Children: A Tertiary Care Hospital Experience from Central India.

ABSTRACT

In severe acute malnutrition, micronutrient deficiency as well as protein energy malnutrition is a major obstacle to growth & development. Iron deficiency dominates the spectrum of nutritional anemia. After taking informed consent, 211 SAM children and 211 age-and sex-matched healthy children with normal nutritional status were enrolled for the study. MUAC was used to diagnose SAM. A 5-part automated hematoanalyzer was used to measure the complete blood count and red cell indices, and the peripheral smear method to determine the red cell morphology. We measured serum ferritin, Vitamin B12, and folic acid using the ELISA method. Compared to controls, children with SAM had significantly lower red cell indices, platelet counts, and white cell counts. The most common clinical symptoms seen in SAM children were diarrhea, pneumonia, acute gastroenteritis, and acute respiratory infection. Children with SAM are more likely to suffer from iron deficiency and B12 deficiency. Severe vitamin B12 deficiency was more frequently associated with severe anemia. The severe anemia in SAM children constantly changes the body's defense mechanism, affecting the haematopoiesis. In this study, haematological indices are recommended for predicting severity of anemia, and hematopoietic changes are described, in order to improve anticipatory care and outcome in children with SAM.
