sFlt-1/PlGF ratio as a predictor of pregnancy outcomes in twin pregnancies: a systematic review

Resumo original em inglês

O que aconteceu

To review the usefulness of the sFlt-1/PlGF ratio to detect adverse pregnancy outcomes related to placental dysfunction in twin pregnancies.

A systematic review in Pubmed-Medline, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, and National Guideline was performed. Studies were selected if they were published in the last 10 years, included a sample size equal to or greater than 10 twin gestations, determined the sFlt-1/PIGF ratio, and revealed the pregnancy outcome of the included patients.

O que encontraram

A total of 11 studies were selected. Outcomes related to the association between sFlt-1/PlGF ratio throughout pregnancy and perinatal outcome, particularly related to placental dysfunction (early and late-onset preeclampsia and FGR), were collected. The vast majority of studies showed an increased sFlt-1/PlGF ratio in twin pregnancies complicated with preeclampsia or other adverse perinatal outcomes compared with uneventful pregnancies. The included articles revealed promising results when evaluating the usefulness of the sFlt-1/PlGF ratio to rule out preeclampsia. The scarce available data regarding FGR suggests that the sFlt-1/PlGF ratio is a promising tool for detecting this pregnancy complication. Data concerning other aspects of the sFlt-1/PlGF ratio, such as its evolution during healthy twin pregnancies or variations according to chorionicity, is limited.

Por que isso importa

The sFlt-1/PlGF ratio in twin pregnancies is useful to detect, and particularly to rule out adverse pregnancy outcomes related to placental dysfunction, such as preeclampsia or FGR.
