The prevalence of anemia in children in the age from six months to five years was almost 40% in 2019, with more than 60% of children in this age group suffering from anemia in the African region (1). In children, anemia is associated with poor cognitive and motor development (1, 2).
Studies on iron supplementation
The most common cause of anemia is iron deficiency (2). McCann and colleagues at the Dept. of Women and Children’s Health, King’s College London, London, UK used the Medonic M-series M32 hematology system to identify anemia in children in rural Gambia, from which capillary (1 and 8 months of age) or venous (5 and 12 months of age) blood samples were collected (3). Iron deficiency was investigated using three individual biomarkers, namely ferritin, soluble transferrin receptor, and hemoglobin concentrations. The results show an association of functional iron status (as determined by sTfR) with neurodevelopment during early infancy (0 to 6 months of age).
Armishty and coworkers at the Dept. of Clinical Sciences, College of Medicine, University of Zakho, Zakho, Kurdistan Region, Iraq used the Medonic M-series hematology system to identify anemia in children from six months to five years (4). They found anemia to be post prevalent in children younger than two years. Anemia was also found to be more prevalent in children with a history of breast-feeding, supposedly due to the lower iron content in breast milk than in artificial milk. The study also confirmed previous findings of a lower prevalence of anemia in children more often eating eggs and meat, supposedly due to the iron content of these foods.
A study by Hasnita and La Sakka at the Nani Hasanuddin College of Health Sciences, Makassar, Indonesia, using the Medonic M-series M32 hematology system , shows that iron supplements of pregnant women can help maximize brain growth and weight of the baby (5).
Taken together, these studies show that iron supplementation during pregnancy and early infancy, can yield neurodevelopmental benefits (3).
Automates hematology analysis in pediatrics
Children are among the most difficult patients from whom to collect blood samples. Of utmost importance is to consider the child’s physical and emotional well-being; yet ensuring safety and efficacy when collecting blood. Vein puncture can be both a traumatic and painful experience.
Compared with adults, pediatric patients have smaller veins and an excess of subcutaneous fat, making visualization and palpation of veins challenging in children (6). Analysis of capillary blood instead of venous blood can therefore be especially useful in pediatrics (Fig 1). A large part of the procedures in neonatal units are performed using capillary blood samples also to avoid effects of blood volume reduction and to reduce the risk of anemia (7, 8).
Fig 1. Medonic M-series M32 hematology analyzer equipped with the micro-pipette adapter (MPA) inlet allows for CBC testing directly from a fingerstick blood sample taken directly from the patient. No vacuum tube, predilution, or tube mixing prior to analysis is required.
