Abstract Objectives: The study was carried out to optimize the phenotypic method to characterize the sickle cell trait (SCT), sickle cell anaemia (SCA) and β-thalassemia (β-TT) suspected sample from tharu community of South Western province-5, Nepal. SCT and SCA were further evaluated by genotypic method employing amplification refractory mutation system (ARMS PCR). Moreover, Glucose 6 Phosphate Dehydrogenase (G6PD) was estimated in those hemoglobinopathy to observe its prevalence. The accurate and reliable method can play an important role in reduction of morbidity and mortality rate. Results: The 100 suspected cases were subjected to phenotypic method adopting cellulose acetate electrophoresis and genotypic metod using ARMS PCR which portraits (5%) SCA positive test showing HBS/HBS, (38%) SCT positive trait HBA/HBS and (36%) cases normal HBA/HBA. β-TT (21%) cases were confirmed by electropherogram. G6PD deficiency was observed in (40%) of SCA, (18.4%) of SCT, (4.8%) of β-TT and (2.8%) in normal cases. Increased G6PD were developed only in SCT (5.3 %) and β-TT (4.8%). The study highlighted sickle cell disorder (SCD) and β-TT as the most common hemoglobinopathy coexisting with G6PD deficiency. Though hemoglobinopathy sometime could be protective in malaria but G6PD deficiency can cause massive hemolysis which may exacerbate the condition.

<b><i>Background:</i></b> Glucose-6-phosphate dehydrogenase (G6PD) deficiency is caused by one or more mutations in the G6PD gene on chromosome X. This study aimed to characterize the G6PD gene variant distribution in Shenzhen of Guangdong province. <b><i>Methods:</i></b> A total of 33,562 individuals were selected at the hospital for retrospective analysis, of which 1,213 cases with enzymatic activity-confirmed G6PD deficiency were screened for G6PD gene variants. Amplification refractory mutation system PCR was first used to screen the 6 dominant mutants in the Chinese population (c.1376G&#x3e;T, c.1388G&#x3e;A, c.95A&#x3e;G, c.1024C&#x3e;T, c.392G&#x3e;T, and c.871G&#x3e;A). If the 6 hotspot variants were not found, next-generation sequencing was then performed. Finally, Sanger sequencing was used to verify all the mutations. <b><i>Results:</i></b> The incidence of G6PD deficiency in this study was 3.54%. A total of 26 kinds of mutants were found in the coding region, except for c.-8-624T&#x3e;C, which was in the noncoding region. c.1376G&#x3e;T and c.1388G&#x3e;A, both located in exon 12, were the top 2 mutants, accounting for 68.43% of all individuals. The 6 hotspot mutations had a cumulative proportion of 94.02%. <b><i>Conclusions:</i></b> This study provided detailed characteristics of G6PD gene variants in Shenzhen, and the results would be valuable to enrich the knowledge of G6PD deficiency.

INTRODUCTION: Homozygous inheritance of the hemoglobin results in sickle cell anemia (SCA), heterozygous inheritance results in sickle cell trait (SCT). Sickle cell anemia and β-thalasemia (β-TT) have been a major health threat for the tharu living in the South-Western Terai of  Nepal. This study is carried out to apply and optimise the phenotypic method and haematological profile to characterise the SCT, SCA and β-TT from suspected tharu community dwellers. MATERIAL AND METHODS: We enrolled 100 suspected cases of hemoglobinopathies of 12-14 years children and ≥15 years adults tharu community dwellers from Dang, Kapilvastu, Nepalgunj, Rupandehi and Nawalparasi of South-Western Nepal from May 2018 to November 2018. Five mililitre of blood was collected in EDTA vial and transported to the laboratory maintaining cold chain. The hematological profile was recorded after investigations. The hemolysate from blood samples were subjected to phenotypic testing by adopting cellulose acetate electrophoresis at pH 8.6. RESULTS: Our result showed the commonest hemoglobinopathy was SCT (38%) followed by β-TT (21%) and SCA (5%). Males were more affected with SCA (60%) while that of females were most affected with β-TT (57.1%). Only 44.7% females were affected with SCT while 42.9% males were affected with β-TT. The significant difference in mean was observed in Hb level (p=0.0001), RBC (p=0.004), MCHC (p=0.015) and RDW (p=0.028) whereas the non-significant difference in mean was observed for glucose 6 phosphate dehydrogenase (G6PD) level (p=0.063) in hemoglobinopathy patients. CONCLUSION: Most cases develop severe type of anemia as shown by change in hematological parameters. This information could advocate for timely counselling before constellation of associated condition appeared in hemoglobinopathy patients.

Basra, southern Iraq, was mapped for haemoglobinopathies and glucose-6-phosphate dehydrogenase [G6PD] deficiency. Of 1064 couples aged 14-60 years recruited from the Public Health Laboratory, 49 had beta-thalassaemia trait, 69 had sickle-cell trait, 2 had haemoglobin D trait, 2 had haemoglobin C trait and 1 had high persistent fetal haemoglobin. Carriers of major beta-globin disorders comprised 11.48%. G6PD deficiency was detected in 133 individuals [12.5%]. Only 10 couples [0.94%] were at risk of having children affected with either sickle-cell disease or beta-thalassaemia major. These defects constitute a real health problem and necessitate a management plan and public health education for early diagnosis and therapy

Introduction Hemoglobin A1c (HbA1c) is recommended for diagnosing and monitoring diabetes. However, in people with sickle cell disease (SCD), sickle cell trait (SCT), α-thalassemia or glucose-6-phosphate dehydrogenase (G6PD) deficiency, HbA1c may underestimate the prevalence of diabetes. There are no data on the extent of this problem in sub-Saharan Africa despite having high prevalence of these red blood cell disorders. Methods Blood samples from 431 adults in northwestern Tanzania, randomly selected from the prospective cohort study, Chronic Infections, Comorbidities and Diabetes in Africa (CICADA), were analysed for SCT/SCD, α-thalassemia and G6PD deficiency and tested for associations with the combined prevalence of prediabetes and diabetes (PD/DM) by HbA1c, using the HemoCue 501 HbA1c instrument, and by 2-hour oral glucose tolerance test (OGTT). Results The mean age of the participants was 40.5 (SD11.6) years; 61% were females and 71% were HIV-infected. Among 431 participants, 110 (25.5%) had SCT and none had SCD. Heterozygous α-thalassemia (heterozygous α+ AT) was present in 186 (43%) of the participants, while 52 participants (12%) had homozygous α-thalassemia (homozygous α+ AT). Furthermore, 40 (9.3%) participants, all females, had heterozygous G6PD deficiency while 24 (5.6%) males and 4 (0.9%) females had hemizygous and homozygous G6PD deficiency, respectively. In adjusted analysis, participants with SCT were 85% less likely to be diagnosed with PD/DM by HbA1c compared to those without SCT (OR = 0.15, 95% CI: 0.08, 0.26, P < 0.001). When using OGTT, in adjusted analysis, SCT was not associated with diagnosis of PD/DM while participants with homozygous α+ AT and hemizygous G6PD deficiency were more likely to be diagnosed with PD/DM. Conclusions HbA1c underestimates the prevalence of PD/DM among Tanzanian adults with SCT. Further research using other HbA1c instruments is needed to optimize HbA1c use among populations with high prevalence of hemoglobinopathies or G6PD deficiency.
