“…On the contrary, Nunes et al . [ 9 ] observed higher serum ferritin level in term SGA neonates as compared with term AGA neonates at birth. In the present study, mean value of serum iron was low in SGA group as compared to AGA group, which is corroborative with the results found in previous study done by Karaduman et al .…”

Background:Hematological values of the newborn babies vary according to the gestational age and intrauterine growth.Objective:The objective of this study is to compare the iron status and red cell parameters in healthy term small for gestational age (SGA) and appropriate for gestational age (AGA) neonates.Materials and Methods:A prospective hospital based study was conducted in a tertiary care teaching institution of central India. 50 AGA and 50 SGA neonates were included in the study and serum iron, serum ferritin and red cell parameters (hemoglobin (Hb), red blood cell (RBC) count and hematocrit (Hct), mean corpuscular volume (MCV), means corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW]) were estimated within 24 h of birth.Results:Serum ferritin levels were significantly low in SGA neonates as compared with AGA (mean 103 vs. 158 ng/ml; P=0.001) neonates. In SGA neonates, mean values of Hb (P=0.001), RBC count (P=0.018) and Hct (P=0.005) were significantly higher than in AGA neonates. Higher values of RDW and MCV were seen in SGA group in comparison with AGA neonates. Similarly, lower values of serum iron, MCH and MCHC were seen in the same group; although, these were non-significant.Conclusion:Despite higher Hb content, SGA neonates are deficient in iron store at birth as indicated by lower serum ferritin levels in them and early iron supplementation should be considered in them.

Background: The normal hematological values in newborns differ significantly from those of infants, older children and adults. In our observation, the values of the newborn babies vary according to the gestational age. At birth the hemoglobin, hematocrit, mean corpuscular volume and mean corpuscular hemoglobin of term newborns are significantly higher than those of older infants and children, and in preterm newborns the differences are even more pronounced. The objective of this study is to evaluate the erythrocyte indices in preterm and term newborns at birth.Methodology: This cross sectional study was conducted in the department of Neonatology in BSMMU from May 2014 to April 2015. A total of 86 newborns; 48 term and 38 preterm were included in the study. Newborns were divided into two groups-term group and preterm group. Erythrocyte indices: hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW) were estimated from cord blood immediately after birth.Results: Mean hemoglobin level in term group was 15.65±1.04g/dl and preterm group was 15.21±0.93g/dl; this difference was statistically significant (p<0.05). Mean hematocrit value was significantly higher in term group (47.27%) than preterm group (46.10%) (p< 0.05). Mean MCH in term group was 34.49 pg and preterm group was 35.83 pg; this difference was statistically significant (p<0.05). Mean RBC count in term group was 4.47 million/cmm and preterm group was 4.35 million/cmm. Mean MCV was higher in preterm group (107.70 fl) than term group (104.58 fl): Mean MCHC was higher in preterm group (33.34g/dl) than term group (33.0g/dl); Mean RDW in term group was 18.18% and in preterm group was 18.58%. These differences were not statistically significant (p>0.05).Conclusion: This study concluded that erythrocyte indices of all newborns are not same; these differ according to gestational age.

RESUMOOs índices hematimétricos são uma importante ferramenta de auxílio no diagnóstico de diversas enfermidades como nas anemias. Com o objetivo de analisar as correlações de VMC e do RDW-CV entre faixa etária e sexo, bem como avaliar a relação entre o VCM e o aumento ou diminuição do RDW-CV, foi realizada coleta dos dados entre 318 pacientes atendidos no ambulatório do Laboratório de Análises Clínicas do Hospital das Clínicas, para fins de utilidade diagnóstica dos indicadores automatizados de anisocitose diante da presença ou ausência de alteração do VCM. Foram analisados estatisticamente os dados de correlação entre VCM e de RDW-CV entre faixa etária e sexo com o teste F. Já para os grupos de VCM -Macrocítico, Normocítico e Microcítico -com relação ao RDW-CV, utilizou-se a correlação de Pearson e teste t-Studant. Não houve diferença significativa com relação ao sexo para o índice de RDW-CV, apenas para o VCM. A análise realizada na determinação do VCM pelas faixas etárias mostrou diferença significativa apenas entre os indivíduos de 18 a 59 anos com os de até 10 anos e os de 11 a 17 anos. Com relação ao RDW-CV todas as relações apresentaram diferença significativa entre si, exceto a estabelecida entre os de 11 a 17 anos com os de 18 a 59 anos. Os testes sobre os grupos de VCM mostrou significativa correlação apenas nos grupos microcítico e macrocítico. No entanto, todos os grupos mostraram resultado significativo no teste t-Studant.Palavras-chave: Índices hematimétricos; anemia; sangue; eritrócitos. ABSTRACTThe red blood cell rates are an important tool to help the diagnosis of several diseases such as anemia. In order to analyze the correlation between MCV and RDW-CV among age and gender, as well as to assess the relationship between MCV and RDW-CV increasing or reduction, it was performed a data collection among 318 patients treated at the Clinical Laboratory Analysis ambulatory of Hospital Clinics, for the diagnostic purpose of the anisocytisis automated indicators before the presence or absence of MCV change. It was statically assessed the correlation data between MCV and RDW-CV among age and gender with the F test. For the MCV groups -Macrocytic, Normocytic and Microcytic -in relation to RDW-CV it was used the Pearson correlation and the Student-t test. There was no significant difference in relation to gender to the RDW-CV rate, only to MCV. The assessment performed in the MCV determination by age showed significant difference only among the subjects between 18 to 59 years old with the subjects up to 10 years old and the ones between 11 to 17 years old. Regarding the RDW-CV, all relationships showed a significant difference among them, except the one established among the subjects between 11 to 17 years old with the ones between 18 to 59 years
