Abstract:

Introduction: The variant hemoglobins (Hb) mostly result from mutations in globin gene, with amino acid substitution in the polypeptide chain. Among the most common structural variants are the HbS, HbC, HbD and HbE. The hemoglobin S gene is a high frequency gene across America and Brazil is more frequent in the Southeast and Northeast. Objectives: To investigate the presence of hemoglobin variants in 15 quilombo communities of Piaui state. Method: The sample was of 1,239 people and hemoglobin were screened by high-performance liquid chromatography (HPLC). Questionnaire was applied related to gender, ethnicity and inbreeding populations. Results: Of the 1,239 samples analyzed 5.4% had sickle cell trait AS, while sickle cell anemia SS and SC showed a rate of 0.8%, were also identified AC hemoglobin (0.2%), AD (0.6%) and DD (0.1%). Of the 1,069 black people declared 84 showed abnormalities of hemoglobin, these 34 people were male while 53 were female. There was the presence of 13 consanguineous marriages among the 84 changes in hemoglobin. Conclusion: The study of hemoglobin variants in 15 former quilombo communities in the state of Piaui contributes to their education in health in the aspects of genetic inheritance of hemoglobin, relevant public health issue, providing subsidies for the implementation of the State Program of Sickle Cell Disease in State of Piaui.
