Background:
- Sickle cell disorders pose a significant health challenge.
- Effective prevention programs are crucial for reducing disease burden.
Purpose of the Study:
- To evaluate the implementation and impact of Cuba's national sickle cell disorder prevention program.
- To assess the effectiveness of a centralized prenatal diagnosis service.
Main Methods:
- Nationwide screening of pregnant women and partners for abnormal hemoglobin.
- Genetic counseling and prenatal diagnosis for at-risk couples.
- Centralized laboratory testing for sickle cell (SS and SC) disorders.
Main Results:
- Over 1000 prenatal tests for sickle cell disorders conducted by 1992.
- Centralized service enabled efficient problem identification and resolution.
Conclusions:
- Cuba's national program demonstrated a systematic approach to sickle cell disorder prevention.
- Centralization of prenatal diagnosis services is effective for managing hemoglobinopathies.
Abstract:
A nationwide programme for the prevention of sickle cell (SS and SC) disorders was initiated in Cuba in 1983. Couples at risk were identified by screening pregnant women and the partners of those who carry an abnormal haemoglobin, followed by genetic counselling and the offer of prenatal diagnosis. Prenatal diagnosis was performed in one laboratory, which had carried out 1068 prenatal tests for Hb SS and SC disorders by the end of 1992. The centralization of the service has permitted rapid identification and resolution of problems.
