Prevalência das hemoglobinas S e C em heterozigose em duas comunidades de povos de Terreiros na cidade de Teresina, Piauí.

Hereditary disease most prevalent in Brazil and worldwide, sickle cell disease is considered a public health problem. Individuals who present in homozygous HbS (SS) show a severe condition of the disease, while individuals with heterozygous HbS AC and AS (sickle cell trait) show no clinical manifestations, giving a normal life to its bearer. The present study aimed to provide support for the consolidation of the state program of sickle cell disease in Piauí state, present the prevalence of sickle cell disease and its genetic inheritance in 62 individuals goers yards of Umbanda Temple. The determination of hemoglobin variants was performed by high performance liquid chromatography (HPLC) using the analyzer-II variant hemoglobins (Biorad). The study revealed the presence of hemoglobin Hb AS (N = 4) 6.5%; Hb AC (N = 3) 4.8%; Hb SC (N = 2) 3.2%. Of the 62 individuals surveyed with Hemoglobin variants, 19 were male while 43 were female. Showed hemoglobin variants 7 women and 2 men. The majority of the study population was constituted by black people (87%), followed by brown (8%) and whites (5%). The sum of the percentage of blacks and browns is 95%. This pilot study supports the hypothesis of a high prevalence of sickle cell disease and its genetic inheritance in the black population of the state of Piauí, requiring its continuity, covering much of the universe of Umbanda Temple, combined with actions of health care.
