First trimester serum angiogenic/anti-angiogenic status in twin pregnancies: relationship with assisted reproduction technology.
BACKGROUND The risk of pre-eclampsia (PE) increases in twin pregnancies, especially when assisted reproduction technologies (ART) are used. The aim of this study was to assess angiogenic/anti-angiogenic factors in maternal serum in the first trimester of twin pregnancies and establish if the mode of conception influences angiogenic status. METHODS This prospective study enrolled women with tw...
متن کاملFirst-trimester serum marker distribution in singleton pregnancies conceived with assisted reproduction.
OBJECTIVE To evaluate marker distribution of free beta-human chorionic gonadotrophin (fbeta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in singleton pregnancies conceived by assisted reproduction techniques (ART). METHODS In vitro fertilization (IVF) (n = 203) and intracytoplasmic sperm injection (ICSI) (n = 192) cases from a database of 14 645 first-trimester combined tests (over...
متن کاملValidation of correction factors for serum markers for first-trimester Down syndrome screening in singleton pregnancies conceived with assisted reproduction.
OBJECTIVE To validate previously computed correction factors for free β-human chorionic gonadotrophin (fβ-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies with hormone treatment and to determine the effect on false-positive rate (FPR). METHODS Retrospective study on 249 IVF and 250 ICSI cases and 20...
متن کاملFirst trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction.
BACKGROUND Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) ...
متن کاملFirst trimester risk assessment for trisomy 21 in twin pregnancies combining nuchal translucency and first trimester biochemical markers.
OBJECTIVE The aim is to describe the performance of first-trimester combined risk assessment in twin pregnancies. METHODS Maternal serum free beta-human chorionic gonadotrophin and pregnancy-associated plasma protein A (PAPP-A) were determined at 8 to 12 weeks and fetal nuchal translucency (NT) was measured at 11 to 13+6 weeks. The individual risk was estimated for each fetus using the combin...
