Obesity is a condition of excess and abnormal fat accumulation. Obese adolescents are atgreater risk of developing iron deficiency anemia with microcytic hypochromic red blood cells(RBC). Iron deficiency in obesity relates to low iron intake, abnormal iron absorption, andincreased iron utilization. The aim of this study was to determine iron intake, hemoglobin level,and RBC indices in faculty of medicine students with obesity. We used descriptive cross-sectional method, involving year of 2016 students in Faculty of Medicine PadjadjaranUniversity with obesity. Pregnant women and students with previous history of thallasemia oranemia were excluded. Iron intake was assessed using Food Frequency Questionnaire.Hemoglobin level and RBC indices were measured in Hasan Sadikin General Hospital. Ironintake of male subjects were adequate in 62,5% subjects and low in 37,5% subjects. Iron intakein female subjects were adequate in 20% subjects and low in 80% subjects. Male hemoglobinlevel were normal and 20% of female subjects had anemia. All male subjects were normochromnormocytic, 40% female subjects were hypochrom microcytic.Keywords: adolescents, hemoglobin level, iron intake, obesity, red blood cell indices

Abstract Background The two most frequently encountered microcytic hypochromic anemias are iron deficiency anemia (IDA) and β-thalassemia trait (β-TT) which need relatively expensive laboratory tests to be differentiated. Objectives This study aims at evaluating the diagnostic utility of different discrimination formulas derived from red blood cell indices from complete blood count in the differentiation of β-TT from IDA. Subjects and Methods This study was conducted on 140 subjects; 40 healthy individuals and 100 patients (60 IDA and 40 β-TT) recruited from outpatient clinics of Ain Shams University Hospitals. They were 45 males and 95 females (M: F 1:2.1), their ages ranged from 19 to 63 years. Patients were subjected to measurement of CBC, iron profile, Hb electrophoresis and HPLC and calculation of RBC indices- derived formulas. Results Comparative studies of different formulas among the studied group shows that England and Fraser (E & F), MDHL, MCHD, MCI and Zaghloul 2 can significantly differentiate between β-TT patients and IDA patients (P was 0.009, 0.008, 0, 0.001 and 0.050 respectively). Evaluation of diagnostic performance (efficacy) of the studied RBCs formulas showed that Zaghloul 2 is the best index in discriminating β-TT from IDA at cut off 66.61 with specificity (97.5%), sensitivity (76.7%) and diagnostic efficacy (85%). This was followed by MCI at cut off 22.73 with specificity (57.5%), sensitivity (85.0%) and diagnostic efficacy (74. %). Then they are followed by MDHL at cut off 1.487 with specificity (50.0%), sensitivity (86.7%) and diagnostic efficacy (72.0), then England and Fraser with cut off 8.9 with specificity (50.0%), sensitivity (80.0%) and diagnostic efficacy (68.0%), and lastly MCHD with cut off 0.296 with specificity (72.5%), sensitivity (61.7%) and diagnostic efficacy (66.0%). Values above these cut off levels indicate β-TT whereas values below these levels indicate IDA except for E&F formula where <8.9 cut off indicate β-TT and >8.9 indicate IDA. Conclusion Zaghloul 2 formula showed the highest efficacy in the differentiation of β-TT from IDA (85%) followed by MCI (74%) and MDHL (72%) then England and Fraser (68%) and lastly MCHD (66%). They can be used for screening in big population, being simple and inexpensive, and then followed by the usual confirmatory tests. Their real use comes in rural areas and primary care facilities where only red blood cell indices are handy. They can be calculated and the cases can be referred to secondary health care to take the confirmatory tests for diagnosis.

Diagnostics of Iron deficiency anemia (IDA) in outpatient pediatric practice is often based on decreased hemoglobin level. Latent iron deficiency diagnostic is not a part of current routine practice.Objective. To study the diagnostic value of red blood cell indices and reticulocyte hemoglobin equivalent in diagnostics of iron deficiency in full-term infants.Children characteristics and research methods. A prospective cohort study of healthy full-term children aged from 6 to 12 months at the children hospitals of Samara and Tolyatti. The laboratory examination included a general blood test to determine the concentration of hemoglobin, the number of red blood cells, red blood cell indices, and reticulocyte hemoglobin equivalent (Ret-He); to determine serum ferritin and C-reactive protein. The AUC (area under the curve) was used to determine the diagnostic value of quantitative indicators. The children with anemia without iron deficiency and children who received iron supplements within 1 month prior to laboratory examination were excluded from the analysis.Results. The study involved 207 children. When diagnosing iron deficiency in children, the highest AUC was found in Ret-He: 0.747 [0.679; 0.816] in 6-months-old children and 0.790 [0.708; 0.871] in 1-year-old children. The Ret-He diagnostic value was higher in children with iron deficiency: AUC 0.826 [0.754; 0.898] in 6- months-old children and 0.865 [0.809; 0.920] in 1-year-old children.Conclusion. Ret-He is a better predictor of iron deficiency in children under 1 year as compared to the red blood cell indices. The diagnostic value of red blood cell indices and Ret-He is higher in case of iron deficiency anemia than in case of iron deficiency conditions.

Abstract Inherited microcytic anemias can be broadly classified into 3 subgroups: (1) defects in globin chains (hemoglobinopathies or thalassemias), (2) defects in heme synthesis, and (3) defects in iron availability or iron acquisition by the erythroid precursors. These conditions are characterized by a decreased availability of hemoglobin (Hb) components (globins, iron, and heme) that in turn causes a reduced Hb content in red cell precursors with subsequent delayed erythroid differentiation. Iron metabolism alterations remain central to the diagnosis of microcytic anemia, and, in general, the iron status has to be evaluated in cases of microcytosis. Besides the very common microcytic anemia due to acquired iron deficiency, a range of hereditary abnormalities that result in actual or functional iron deficiency are now being recognized. Atransferrinemia, DMT1 deficiency, ferroportin disease, and iron-refractory iron deficiency anemia are hereditary disorders due to iron metabolism abnormalities, some of which are associated with iron overload. Because causes of microcytosis other than iron deficiency should be considered, it is important to evaluate several other red blood cell and iron parameters in patients with a reduced mean corpuscular volume (MCV), including mean corpuscular hemoglobin, red blood cell distribution width, reticulocyte hemoglobin content, serum iron and serum ferritin levels, total iron-binding capacity, transferrin saturation, hemoglobin electrophoresis, and sometimes reticulocyte count. From the epidemiological perspective, hemoglobinopathies/thalassemias are the most common forms of hereditary microcytic anemia, ranging from inconsequential changes in MCV to severe anemia syndromes.

AbstractAbnormalities of red blood cell (RBC) indices may affect glycated haemoglobin (HbA1c) levels. We assessed the influence of haemoglobin (Hb) and mean corpuscular volume (MCV) on the performance of HbA1c in detecting dysglycaemia among reproductive aged women planning to conceive. Women aged 18–45 years (n = 985) were classified as normal (12 ≤ Hb ≤ 16 g/dL and 80 ≤ MCV ≤ 100 fL) and abnormal (Hb < 12 g/dL and/or MCV < 80 fL). The Area Under the Receiver Operating Characteristic (AUROC) curve was used to determine the performance of HbA1c in detecting dysglycaemic status (prediabetes and diabetes). There were 771 (78.3%) women with normal RBC indices. The AUROCs for the normal and abnormal groups were 0.75 (95% confidence interval 0.69, 0.81) and 0.80 (0.70, 0.90), respectively, and were not statistically different from one another [difference 0.04 (− 0.16, 0.08)]. Further stratification by ethnicity showed no difference between the two groups among Chinese and Indian women. However, Malay women with normal RBC indices displayed lower AUROC compared to those with abnormal RBC indices (0.71 (0.55, 0.87) vs. 0.98 (0.93, 1.00), p = 0.002). The results suggest that the performance of HbA1c in detecting dysglycaemia was not influenced by abnormal RBC indices based on low Hb and/or low MCV. However, there may be ethnic variations among them.
