Resumo
Background: The high frequency of hemoglobinopathies in Brazil constitutes a public health problem and thus
educational and preventive measures are necessary to reduce the incidence. Genetic guidance, a modality of
genetic counseling, and family screening are measures that can assist in reproductive decisions and mitigate
clinical, psychological and social problems of families with these disorders.
Objetive: The objective of the current study was to evaluate the effectiveness of educational and preventive
measures for hemoglobinopathies using genetic guidance and laboratory screening of families.
Methods: The diagnoses of patients with hemoglobinopathies were confirmed and then the level of knowledge
about their disease was evaluated and genetic guidance was provided. Three months later, the level of
assimilated information of these patients was evaluated. In addition, laboratory diagnosis of family members
was carried out.
Results: Diagnosis of sickle cell anemia was confirmed for most patients. Moreover, the majority of the patients who had
a low level of knowledge before genetic guidance (68.8%) demonstrated a higher level of assimilated information after
the process (81.8%). Almost 70% of the family members had hemoglobin changes and some had hemoglobinopathies
(2.6%). They were duly informed about the results of the examinations, which made it possible to investigate further.
Conclusion: Genetic guidance and family screening were effective preventive and educational measures that
improved the quality of life of patients, preventing complications and sequels and allowed the referral of those
who may transmit altered genes for clinical diagnosis and to genetic counseling services.
