Abstract

Down syndrome (DS) is one of the main genetic abnormalities of newborns.
Therefore, prenatal diagnosis of this syndrome is of paramount importance to the family and the community.
The microbiota system is important in early brain development. We tried to study and compare
gut microbiota (GM) composition in pregnancies that resulted in DS neonates with pregnancies
that resulted in healthy children. The study population consisted of 21 pregnant women having delivered
DS newborns (group 1) and 22 pregnant women who had given birth to healthy newborns
(group 2). The GM composition was determined and compared between the two groups. There were
no significant age and gestational age differences between the two groups (p>0.005 both). Regarding
GM analysis, microorganisms of the families Clostridiaceae and Pasteurellaceae were more abundant in
the group of women having delivered DS neonates than the group of women having delivered healthy
newborns (p<0.05). The results of our pilot study showed that the GM system might have a role in the
pathophysiology of DS. The GM changes may be used in the prenatal diagnosis and prevention of this
syndrome. Further studies are needed in this field.
