Estudo dos polimorfismos do gene da adiponectina em mulheres com hipertensão gestacional e pré-eclâmpsia

Abstract in Portuguese
Introdução: a adiponectina está envolvida na homeostase energética, através da regulação do metabolismo glicídico e lipídico. Adicionalmente, apresenta propriedades anti-inflamatórias e antiateroscleróticas. Polimorfismos no gene da adiponectina (ADIPOQ) podem modular as concentrações de adiponectina. A influência desses polimorfismos no desenvolvimento da hipertensão gestacional (HAG) e da pré-eclâmpsia (PE) é desconhecida. Objetivo: o objetivo deste trabalho foi analisar a influência dos polimorfismos no gene ADIPOQ sobre o desenvolvimento da hipertensão gestacional e da pré-eclâmpsia. Pacientes e métodos: Foram estudadas 401 gestantes sendo 161 grávidas saudáveis (GS), 113 com HAG e 127 com PE. Os polimorfismos do gene ADIPOQ -11391G>A (rs17300539), -11377C>G (rs266729), 45T>G (rs2241766) e 276G>T (rs1501299) foram genotipados através de discriminação alélica por reação de PCR em tempo real. Os haplótipos foram inferidos através do programa PHASE 2.1. Resultados: não foram observadas diferenças estatisticamente significativas nas freqüências genotípicas e alélicas dos polimorfismos estudados. Na analise dos haplótipos, observamos pequenas diferenças nas freqüências haplotípicas entre os grupos estudados, no entanto, nenhuma destas diferenças foi estatisticamente significativa (P>0,05). Conclusão: Não encontramos nenhuma associação entre as variantes genotípicas e alélicas dos polimorfismos no gene ADIPOQ com o desenvolvimento de hipertensão arterial gestacional e pré-eclâmpsia.

Abstract in English
Introduction: adiponectin is involved in energy homeostasis by regulating glucose and lipid metabolism. Additionally, it presents anti-inflammatory and anti-atherosclerotic functions. Polymorphisms in adiponectin gene (ADIPOQ) can modulate the concentrations of adiponectin. The influence of these polymorphisms on the development of gestational hypertension (GH) and preeclampsia (PE) is unknown. Aim: The aim of this work was to examine the influence of polymorphisms in the gene ADIPOQ on the development of gestational hypertension and preeclampsia. Patients and Methods: we studied 401 pregnant women: 161 healthy pregnant (HP), 113 pregnants with gestational hypertension (GH) and 127 pregnants with preeclampsia (PE). Polymorphisms ADIPOQ -11391G>A (rs17300539), - 11377C>G (rs266729), 45T>G (rs2241766) and 276G>T (rs1501299) were genotyped by allelic discrimination by PCR in real time. Haplotypes were inferred using the PHASE 2.1 program. Results: there were no statistically significant differences in allele and genotype frequencies of the polymorphisms studied. In the analysis of haplotypes, we observed small differences in haplotype frequencies between groups, however, none of these differences was statistically significant (P> 0.05). Conclusion: we found no association between the genotypic and allelic variants of the ADIPOQ gene polymorphisms with the development of gestational hypertension and preeclampsia.
