Newborn screening in Colombia: The experience of a private program in Bogotá
Abstract
Introduction. The first neonatal screening program in Colombia – PREGEN – was set up in the medical private sector of Bogotá in 1988. We report the results from recent years that, given the scarcity of similar information in our country, may help estimate the frequency of the evaluated neonatal disorders and which ones should be included in the neonatal screening programs in our country.
Objective. To describe the results of PREGEN´s newborn screening program between 2006 and 2019.
Materials and methods. We analyzed databases and other informative documents preserved in PREGEN from the 2006-2019 period.
Results. One in every 164 newborns screened in our program had an abnormal hemoglobin variant, and one in every 194 carried some hemoglobin S variant. Glucose-6-
phosphate dehydrogenase deficiency and congenital hypothyroidism are next as the more common disorders.
Conclusions. Abnormal hemoglobin causes the most frequent monogenic disorder in the world. Glucose-6-phosphate dehydrogenase deficiency is the most common enzymopathy affecting nearly 400 million individuals worldwide. Since both disorders are more common in people of African descent and confer some resistance to malaria, we believe that screening for both disorders may be more relevant in the areas with African ancestry in our country.
