    In: Journal of Medicine and Pharmacy, Hue University of Medicine and Pharmacy
    Abstract: Background: Thalassemia is the most common monogenic disease worldwide. The severity of thalassemia depends on the degree of imbalance between the α-globin and β-globin chains. The aims of the current study were (1) to describe clinical and hematological characteristics of β-thalassemia patients; and (2) to investigate mutations of β-globin gene using Sanger sequencing, as well as the association between β-globin genotype and severity of β-thalassemia. Materials and method: 57 β-thalassemia patients treated at Hue Central Hospital were examined by sequencing the whole β-globin gene. Results: 80.7% with β-thalassemia intermedia, 19.3% with β-thalassemia major. Patients had 100% anemia, 75.4% splenomegaly, 50.9% hepatomegaly, 38.6% thalassemia facies, 28.1% jaundice and 15.8% iron overload; The red blood cell indices were decreased: Hb 7.5 ± 1.3 g/dL, MCV 70.9 ± 8.4 fL, MCH 20.5 ± 2.1 pg. Hemoglobin composition included HbA 35.2 ± 33.9%, HbA2 6.1 ± 2.7%, HbF 24.8 ± 18.0%, and HbE 38.6 ± 15.2%. Nine β-globin gene mutations were observed. The most common genotype was βE/β0, which occupied 80.7%. The βE/βA, β0/βA and βE/β+ genotypes were only found in β-thalassemia intermedia individuals, while the β0/β0 genotype was limited to β-thalassemia major patients. The βE/β0 genotype was seen in both types. Conclusion: There was differences in age of blood transfusion initiation between the genotypes. Among them, the β0/β0 genotype was the most severe. Key words: β-thalassemia intermedia, β-thalassemia major, genotype.

    Molecular characterization of alpha globin and beta globin genes in patients with hemoglobinopathies in Central Vietnam
    Hue University of Medicine and Pharmacy ; 2022
    In:  Journal of Medicine and Pharmacy
    Details
    In: Journal of Medicine and Pharmacy, Hue University of Medicine and Pharmacy
    Abstract: Background: Hemoglobinopathy is the most common monogenic disease worldwide. The aims of the current study were: (1) to investigate some hematological characteristics of patients with hemoglobinopathies; and (2) to detect the mutation of α-globin and β-globin genes, as well as the association between genotype and degree of anemia. Materials and method: 251 patients with hemoglobinopathies were examined for the α-globin or β-globin gene mutations. Results: 51% were the carriers, and 49% were thalassemia intermedia or thalassemia major. Hematological characteristics were suitable for α-thalassemia or β-thalassemia. Elevenβ-globin gene mutations were observed. The β0/βA, βE/βA, βE/βE, βE/β+, β+/β+ genotypes were only found in β-thalassemia intermedia individuals; the β0/β0 genotype was limited to β-thalassemia major patients; the β+/β0 and βE/β0 genotypes were seen in both types. Four α-globin gene mutations were observed. All α-thalassemia patients were intermedia, the most common genotype was --SEA/-α3.7. Conclusion: There were differences in anemia degree between β-globin genotypes Key words: hemoglobinopathies, α-globin, β-globin.

    PERIPHERAL BLOOD CELL CHARACTERISTICS OF LAOTIAN STUDENTS IN HUE
    Hue University of Medicine and Pharmacy ; 2020
    In:  Journal of Medicine and Pharmacy
    Details
    In: Journal of Medicine and Pharmacy, Hue University of Medicine and Pharmacy
    Abstract: Background: To evaluate the complete blood count of Laotian students in Hue city. Materials and method: A cross-sectional study on 400 Lao students who were examinated the complete blood count at Department of Hematology, Hue University of Medicine and Pharmacy from September 2019 to May 2020. Results: 400 Lao students (male/female = 1/1.2), the students who came from Salavan province accounted for the highest percentage (22.25%). The mean of age was 24.78 ± 6.44 (17 - 44). The mean of red blood cells (RBC) was 5.13 ± 0.73 T/L and of hemoglobin in the study group was 129.27 ± 18.58 g/L. The percentage of students with anemia was 13.5% and there were 3 students with severe anemia. The mean of mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were respectively 81.27 ± 9.32 fL (49.2 - 103.9) and 25.50 ± 3.56 pg (11.8 - 33.2). The mean of white blood cells (WBC) and platelets (PLT) were respectively 7.42 ± 2.29 G/L and 272.33 ± 83.62 G/L. There was a correlation between anemia and age (p 〈 0.05), mainly in 26 - 40. There was significant difference about RBC and Hb between anemic group and non-anemic group (p 〈 0.05). Conclusion: It is essential to check the complete blood count of Laotian students to evaluate anemia and screen hemoglobinopathies. Keywords: Laotian students, red blood cell (RBC), white blood cell (WBC), platelet (PLT), hemoglobin (Hb)

    THE DNA METHYLATION STATUS IN PRESENT DAY POPULATIONS LIVING IN AREAS OF VIETNAM SUBJECTED TO AGENT ORANGE SPRAYING DURING THE WAR IN NAM DONG AND A LUOI, THUA THIEN HUE PROVINCE

    Abstract: Introduction: Agent Orange was the most extensively used among herbicides sprayed on Vietnam territory during the Vietnam War. Its by-product, 2,3,7,8-tetrachlorodibenzo-paradioxin (Dioxin), is an extremely toxic and persistent chemical. The effects of this spraying on both Vietnamese and United States Veterans health has been reported in many publications. However, there wasn’t any study of the effects at the molecular level of the residual Dioxin in the environment on present Vietnamese civilians living in contaminated areas. Objective: To investigate the association between residual Agent Orange/Dioxin in the environment and the alterations of DNA methylation in the peripheral blood of the present day Vietnamese population living in spraying areas. Methods: Cross-sectional study. The subjects were 188 individuals who came to Hue University Hospital for health care: 94 individuals for case group from sprayed areas (A Luoi and Nam Dong, Thua Thien Hue Province), and 94 individuals for the control group from non-sprayed areas (Quang Binh to North Vietnam). MALDI-TOF MS technique was used to detect the alterations of DNA methylation of CYP1A1 gene. Results: Among 22 CpG position of CYP1A1 gene were investigated, there were the DNA hypomethylation at CpG_2.3.4, CpG_5, CpG_12.13 in case group compared to the control (p 〈 0.05). After dividing case group into 2 subgroups, we found the significant DNA hypomethylation at CpG_2.3.4, CpG_5, CpG_9, CpG_10, CpG_11, CpG_12.13, CpG_17, CpG_18.19 in subgroup CASES_F_P compared to CASES_NON_F_P also control group (p 〈 0.05). Conclusions: Individuals living in A Luoi and Nam Dong– the Dioxin contaminated areas– had DNA hypomethylation in CYP1A1 gene. The DNA hypomethylation seem not due to the effects of residual Dioxin in the environment in present day, it was likely to be inherited by epigenetic way from the DNA methylation alterations on their parents who had directly exposure to that spraying. This theory should be verified through extensive studies with CASES_F_P family and more genes will be investigated. Key words: Agent Orange, Dioxin, DNA methylation, CYP1A1
