Most common microcytic hypochromic anemias are iron deficiency anemia (IDA) andβ-thalassemia trait (BTT), in which oxidative stress (OxS) has an essential role. Catalase causes detoxification of H2O2in cells, and it is an indispensable antioxidant enzyme. The study was designed to measure erythrocyte catalase activity (ECAT) in patients with IDA (10) or BTT (21), to relate it with thalassemia mutation type (β0orβ+) and to compare it with normal subjects (67). Ninety-eight individuals were analyzed since September 2013 to June 2014 in Tucumán, Argentina. Total blood count, hemoglobin electrophoresis at alkaline pH, HbA2, catalase, and iron status were performed.β-thalassemic mutations were determined by real-time PCR. Normal range for ECAT was 70,0–130,0 MU/L. ECAT was increased in 14% (3/21) of BTT subjects and decreased in 40% (4/10) of those with IDA. No significant difference (p=0,245) was shown between normal and BTT groups, while between IDA and normal groups the difference was proved to be significant (p=0,000). Inβ0andβ+groups, no significant difference (p=0,359) was observed. An altered ECAT was detected in IDA and BTT. These results will help to clarify how the catalase activity works in these anemia types.

Objective. Several discriminating techniques have been proposed to discriminate between β-thalassemia trait (βTT) and iron deficiency anemia (IDA). These discrimination techniques are essential clinically, but they are challenging and typically difficult. This study is the first application of the Bayesian tree-based method for differential diagnosis of βTT from IDA. Method. This cross-sectional study included 907 patients with ages over 18 years old and a mean (±SD) age of 25 ± 16.1 with either βTT or IDA. Hematological parameters were measured using a Sysmex KX-21 automated hematology analyzer. Bayesian Logit Treed (BLTREED) and Classification and Regression Trees (CART) were implemented to discriminate βTT from IDA based on the hematological parameters. Results. This study proposes an automatic detection model of beta-thalassemia carriers based on a Bayesian tree-based method. The BLTREED model and CART showed that mean corpuscular volume (MCV) was the main predictor in diagnostic discrimination. According to the test dataset, CART indicated higher sensitivity and negative predictive value than BLTREED for differential diagnosis of βTT from IDA. However, the CART algorithm had a high false-positive rate. Overall, the BLTREED model showed better performance concerning the area under the curve (AUC). Conclusions. The BLTREED model showed excellent diagnostic accuracy for differentiating βTT from IDA. In addition, understanding tree-based methods are easy and do not need statistical experience. Thus, it can help physicians in making the right clinical decision. So, the proposed model could support medical decisions in the differential diagnosis of βTT from IDA to avoid much more expensive, time-consuming laboratory tests, especially in countries with limited recourses or poor health services.

Introduction: In developing countries like Nepal, iron deficiency anemia (IDA) is one of the major concern. The high rate incidence has been related to insufficient  iron  intake, accompanied  by chronic  intestinal  blood  loss  due  to parasitic  and  malarial infections. Therefore, a study was conducted to evaluate the prevalence of IDA in anemic patients of Universal College of Medical Sciences-Teaching Hospital (UCMS-TH), South Western region, Nepal. Material and Method It was a hospital based cross sectional study comprised of 100 anemic patients. Their detailed medical history and lab investigations, focusing on hematological parameters were documented. Peripheral smear examination and serum ferritin estimation were done to observe red cell morphology and iron status respectively.  Results: This study revealed that out of 100 anemic patients, 35% were that of IDA. The most affected age group was 21-40 years with frequency 42.55%. IDA was more common in females (42.85%) than in male (21.62%). Out of 100 anemic patients, microcytic hypochromic anemia was predominant in 47% followed by macrocytic anemia (31%) and then normocytic normochromic anemia (22%). Out of 47 microcytic hypochromic anemic patients, 12 had normal serum ferritin. There was a statistical significant difference in Hb (p=0.011), MCV (p=0.0001), MCH (p=0.0001), MCHC (p=0.0001) and serum ferritin (p=0.0001) among all types of anemia. There was a statistical significant positive correlation of ferritin with Hemoglobin (0.257, p= 0.01), MCV (0.772, p= 0.0001), MCH (0.741, p=0.0001) and MCHC (0.494, p=0.0001).  Conclusion: The peripheral smear in conjunction with serum ferritin estimation needs to be included for susceptible individuals to screen the IDA and other types of anemia.

Background: Iron deficiency anemia (IDA) and beta thalassaemia trait (BTT) are two of the most common causes of microcytic anemia.It is essential to differentiate between the two, so as to avoid unnecessary iron therapy which is contraindicated in beta thalassaemia .We retrospectively evaluated the reliability of various indices for differential diagnosis of microcytosis and 𝛽-TT in the same patient groups .Methods: A total of 200 patients were evaluated. We calculated 6 discrimination indices in all patients with anemia or suspected beta thalassemia. None of the subjects had  combined  IDA and 𝛽-TT. The patient groups were evaluated according to  the Mentzer, Shine and Lal, England and Fraser,Srivastava, Green and King, Ricerca.Results: According to percentage correctly diagnosed criteria, Ricerca  and Mentzer  index are considered as the two best discrimination indices in differentiation between β thalassemia trait  and iron deficiency anaemia .Youden’s index showed the following ranking with respect to the indices’ ability to distinguish between 𝛽-TT and IDA, Ricerca index >  Mentzer index > Green and King index >  Srivastava index >  Shine and Lal index > England and Fraser index.Conclusions: Ricerca  and Mentzer  index are considered as the two best discrimination indices in differentiation between β thalassemia trait  and iron deficiency anaemia.Keywords: Iron deficiency anemia (IDA) and beta thalassaemia trait (𝛽-TT)

The purpose of this work is to develop a hematocrit-independent method for the detection of beta-thalassemia trait (β-TT) and iron deficiency anemia (IDA), through the rheological characterization of whole blood samples from different donors. The results obtained herein are the basis for the development of a front microrheometry point-of-care device for the diagnosis and clinical follow-up of β-TT patients suffering hematological diseases and alterations in the morphology of the red blood cell (RBC). The viscosity is calculated as a function of the mean front velocity by detecting the sample fluid-air interface advancing through a microfluidic channel. Different viscosity curves are obtained for healthy donors, β-TT and IDA samples. A mathematical model is introduced to compare samples of distinct hematocrit, classifying the viscosity curve patterns with respect to the health condition of blood. The viscosity of the fluid at certain shear rate values varies depending on several RBC factors such as shape and size, hemoglobin (Hb) content, membrane rigidity and hematocrit concentration. Blood and plasma from healthy donors are used as reference. To validate their potential clinical value as a diagnostic tool, the viscosity results are compared to those obtained by the gold-standard method for RBC deformability evaluation, the Laser-Optical Rotational Red Cell Analyzer (LoRRCA).

INTRODUCTION- Iron deficiency anemia and thalassemia syndromes,especially beta thalassemia trait (BTT),are the two most commonly ccuring microcytic hypochromic anemias highly prevalent in countries like India. Iron deficiency anemia is the first most common cause of anemia in pregnancy,beta thalassemia trait is the second most frequent cause of anemia of pregnancy. Patients with thalassemia trait shows an increased incidence of anemia during the second trimester of pregnancy. Beta Thalassemia Trait (BTT) patients are usually asymptomatic and ignorant of their carrier state unless diagnosed by testing. Screening for thalassemia can be done by measuring HbA2 levels MATERIAL AND METHOD- This is a retrospective study. The data were collected from a clinic and associated st pathology in Shivpuri and a private maternity hospital in Gwalior from 1 January 2019 to 30 June 2021.94 patients were included in the study.All pregnant women between the age of 18-45 years and at any gestational age with hemoglobin level <10g/dL and microcytic hypochromic anemia (report of CBC) were included in the study. High-Performance Liquid Chromatography (HPLC) and serum ferritin report were collected. RESULTS- In our study the most common age group in which the anemia was found between 19-35 years (80.85%).Most of the patients were primigravida (44.68%),between 26-37 wks of gestational age (82.97%),from a rural area (70.21%). Only 2 patients had a family history (2.12%) of beta-thalassemia and 6 patients had a history (6.38%) of blood transfusion. In our study moderate anemia was found in 55.31% of cases followed by mild anemia 25.53% and severe anemia 19.14%. In our study iron deficiency anemia was found in 87.23% only minor Beta-thalassemia was found to be 4.25%, of the patient,and the coexistence of iron deficiency anemia and beta-thalassemia in pregnant women is 8.51%. In our study total of 12 patients (4 cases of only minor beta-thalassemia and 8 cases of minor beta-thalassemia associated with IDA) The prevalence rate of beta-thalassemia in our study was 7.8%. CONCLUSION- the recommendation is to diagnose beta-thalassemia in pregnant patients is essential to give proper treatment.The screening of pregnant patients prevents unnecessary parental iron therapy and iron overload in case of anemia.further studies are needed in this field and less expensive and accurate methods should come in place.

Purpose. Iron deficiency anemia is an important public health problem. Also it is considered to be a risk factor for many diseases. The study demonstrates the iron deficiency anemia frequency in glaucoma patients and compares with the normal subjects. We aimed to determine the iron deficiency anemia frequency in glaucoma patients.Methods. Prospective, controlled study in a single university hospital setting. A total of 130 normal subjects (Group 1) and 131 glaucoma patients (Group 2) were included. The erythrocytes parameters, hemoglobin, red blood cell, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, and red blood cell distribution width, and iron status indicators, Fe (iron), total iron binding capacity, and ferritin of the cases, in normal subjects and glaucoma patients were compared.Results. There was no statistically significant difference for the erythrocyte parameters between the groups (p≥0.05). The number of the patients with iron deficiency anemia in both groups was similar. No statistically significant difference was found in the comparison of erythrocyte parameters and iron status indicators values according to the number of antiglaucomatous agents and visual field changes according to the presence of anemia in Group 2 (p≥0.05). A statistically significant difference was found only in MCH when the erythrocyte parameters and iron status indicators values of the cases in glaucoma patients were compared with the glaucoma duration (p<0.05).Conclusion. The iron deficiency anemia frequency was like the normal population in glaucoma patients.
