Item Hemoglobinopathies in South Gujarat population and incidence of anemia in them.(2012-09) Patel, Ankur G; Shah, Avani P; Sorathiya, Smita M; Gupte, Snehalata CObjective: To Screen of South Gujarat population for determination of prevalence of different hemoglobinopathies particularly beta thalassemia trait (BTT) and sickle cell trait (SCT) and find out the incidence of anemia in them. Material and Methods: The present study screened 32,857 samples of students from different school and colleges in South Gujarat. Blood samples were initially tested for solubility test and complete hemogram on hematology analyzer. Samples having MCV (≤78), MCH (≤28) and/or positive solubility test were investigated for Hb electrophoresis on cellulose acetate membrane (pH 8.6). Hb A 2 level ≥3.5% was considered as diagnostic for BTT. High performance liquid chromatography on Biorad Hb variant system was done on samples having doubtful results. Result: Overall prevalence of BTT and SCT in South Gujarat was 4.4% and 1.3% respectively. Gamit, Vasava, Chaudhary, and Mahyavanshi castes had high prevalence of BTT (15.9%, 13.6%, 12.6%, and 6.9%) as well as SCT (22.2%, 15.2, 22.3, and 4.2%) respectively. Other communities like Lohana (10.8%), Sindhi (10.2%), Prajapati (6.3%), and Ghanchi (6.2%) also showed higher prevalence of BTT. Incidence of mild to moderate anemia was higher in BTT and SCT compared to non-BTT or non-SCT subjects. Conclusion : Study suggests that BTT is the most prevalent hemoglobinopathy in South Gujarat. β-thalassemia and Sickle cell anemia are highly prevalent in Mahyavanshi, Chaudhary, Gamit, Vasava and Rohit. Prajapati, Lohana, Leva Patel, and Ghanchi have β- thalassemia risk. SCT is more frequently detected in Dhodia Patel and Kukanas.Item Prevalence and hematological profile of β-thalassemia and sickle cell anemia in four communities of Surat city.(2012-05) Bhukhanvala, Dipal S; Sorathiya, Smita M; Shah, Avani P; Patel, Ankur G; Gupte, Snehalata CBackground: From the data of transfusion-dependent thalassemia major cases, the 4 communities (Muslim, Dhodia Patel, Kachhiya Patel, and Modh Bania) with high prevalence but not studied methodically were selected. Aim: The aim of this study is to find prevalence of β-thalassemia and sickle cell anemia in 4 selected communities and also to evaluate hematological profile in them. Materials and Methods: For screening of β-thalassemia trait (BTT) and sickle cell trait (SCT), all samples were tested for red cell indices, solubility, HbA 2 level and doubtful cases confirmed on HPLC. Statistical Analysis: Mean ± SD, χ2 and 't' tests were used to evaluate the significance. Results and Conclusion: Among 4 selected communities, the highest prevalence of BTT was observed in Modh Bania (6.2%) and Kachhiya Patel (6.05%) and that of SCT in Dhodia Patel (14.0%). Significantly higher prevalence of BTT was observed in Memon ( P < 0.0001) and of SCT in Khalifa 6.6% ( P < 0.0001) compared to other Muslim sub castes. Anemia was more prevalent in BTT compared to non-BTT and non-SCT subjects. 80% of Dhodia Patel non-BTT and non-SCT subjects showed microcytic red cell morphology. Their Mean ± SD Hb concentration was 12.1 ± 1.73, hence iron deficiency cannot be a sole reason. This community needs α-thalassemia and iron studies.
