VARGAS AGUILAR, Víctor Manuel; BELTRAN BELTRAN, Karen María y ARROYO ALVAREZ, Karina. Pathophysiology of fetal programming and its impact on the future health. Ginecol. obstet. Méx. [online]. 2023, vol.91, n.8, pp.588-599. Epub 17-Nov-2023. ISSN 0300-9041. https://doi.org/10.24245/gom.v91i8.8688.
BACKGROUND:
During intrauterine life, alterations in the fetal microenvironment caused by maternal nutritional and metabolic imbalances may leave epigenetic imprints and persistent effects on fetal adult life that will predispose the fetus to future chronic diseases.
OBJECTIVE:
To carry out a systematic review of the pathophysiology of fetal programming and its impact on the future health of the fetus.
METHODOLOGY:
Search in the PubMed database of articles published in the last 10 years, in English or Spanish, with the MeSH "fetal programming"; "pathophysiology", with their corresponding translation. Original and review articles with PRISMA criteria for systematic reviews were included.
RESULTS:
Thirty-eight articles were found, and seven were added for complementary information and support for discussion. In their analysis the relationship between the reported pathophysiological conditions of under-, under- and over-nutrition, gestational diabetes mellitus, obesity, insulin resistance, glucocorticoids and pre-eclampsia with diseases of childhood, adolescence and adulthood is clear. Evidence of endocrine disruptors, melatonin and dysbiosis was found with diseases of childhood and adulthood. Also, disruption of angiogenesis during lung development leads to pulmonary arterial hypertension and emphysema, all caused by epigenetic fetal programming. Differences were found in the methylation pattern of preterm placentas compared to term placentas.
CONCLUSIONS:
Abnormalities that occur during pregnancy modify fetal programming and give rise to the diseases that will appear during childhood, adolescence, and adulthood, because of changes in the methylation pattern of genes.
