BACKGROUND: Placental protein-13 (PP13) is involved in placental invasion and has been suggested as a maternal serum marker of preeclampsia (PE) development. However, the discriminatory ability of PP13 in first trimester has not been completely clarified. METHODS: PP13 was measured in first trimester (week 10+3-13+6) maternal serum from 120 PE pregnancies and 267 control pregnancies and was correlated with clinical parameters. The population screening performance of PP13 in combination with the PE markers pregnancy associated plasma protein A (PAPPA) and free leptin index (fLI) was assessed by Monte Carlo simulation...

PURPOSE: First trimester risk assessment for chromosomal abnormalities plays a major role in the contemporary pregnancy care. It has evolved significantly since its introduction in the 1990s, when it essentially consisted of just the nuchal translucency measurement. Today, it involves the measurement of several biophysical and biochemical markers and it is often combined with a cell-free DNA (cfDNA) analysis as a secondary test. METHODS: A search of the Medline and Embase databases was done looking for articles about first trimester aneuploidy screening...

We enrolled 151 healthy mother/newborn couples and 26 with gestational diabetes mellitus (GDM). HLA-G and PAPP-A plasma levels were measured by ELISA at first and second trimesters, at delivery, and in cord blood. HLA-G 14 bp ins/del and PAPP-A A/C polymorphisms were genotyped. HLA-G del/del and PAPP-A C/C genotypes were more frequent among GDM mothers than controls. We observed a genetic epistasis between the two polymorphisms: the HLA-G del/del and PAPP-A C/C combination was carried by 8% of GDM mothers and 1...

Introduction Studies conducted in the recent past have demonstrated the role of inflammation, obesity and dysfunctional insulin signaling as contributing factors in the pathogenesis of acute coronary syndrome (ACS). However, pharmacological interventions targeting a single pathway have not proven useful in the long run. This indicates that a synergism occurs between the various risk factors and hence calls for a combinatorial approach. This study was planned to study the interplay, if any, between pregnancy associated plasma protein-A (PAPP-A), inflammation and adiposity in patients with ACS...

Pregnancy-associated plasma protein-A (PAPP-A) knockout (KO) mice, generated through homologous recombination in embryonic stem cells, have a significantly increased lifespan compared to wild-type littermates. However, it is unknown whether this longevity advantage would pertain to PAPP-A gene deletion in adult animals. In the present study, we used tamoxifen (Tam)-inducible Cre recombinase-mediated excision of the floxed PAPP-A (fPAPP-A) gene in mice at 5 months of age. fPAPP-A mice, which were either positive (pos) or negative (neg) for Tam-Cre, received Tam treatment with quarterly boosters...

OBJECTIVE: The development of methods for pre-delivery prediction of low-birth-weight newborns would be clinically advantageous because low birth weight contributes to a high infant mortality rate. This study was performed to examine whether maternal blood biomarkers of placentation can be used to predict low-birth-weight newborns. METHODS: Ten databases, including PubMed/Medline, were searched. Any English language study that provided all of the true- and false-positive and true- and false-negative results of this prediction was included in the analysis...

Risk stratification and patient management in heart failure (HF) is difficult due to the unpredictable progression of the disease, necessitating the development of reliable diagnostic biomarkers to facilitate decision-making in clinical practice. Pregnancy-associated plasma protein-A (PAPP-A) is a marker of arteriosclerotic heart disease. PAPP-A is a serum protease, which is involved in the insulin-like growth factor 1 (IGF-1) axis where it is inhibited by the proform of the eosinophil major basic protein (proMBP)...
