Could first-trimester assessment of placental functions predict preeclampsia and intrauterine growth restriction? A prospective cohort study.

Objective: To examine the role of first-trimester uterine artery Doppler, serum β-hCG and pregnancy-associated placental protein-A (PAPP-A) in prediction of preeclampsia and IUGR.

Methods: A total of 100 pregnant women in the 11-14 weeks' gestation were examined using uterine artery Doppler, serum β-hCG and PAPP-A. All women were followed-up for development of preeclampsia or IUGR.

Interleukin-18 -607C/A gene polymorphism in Egyptian asthmatic children.

Background: Asthma is a multifactorial respiratory disease determined by interactions of multiple disease susceptibility genes and environmental factors. Interleukin (IL)-18 is an important cytokine for initiating and perpetuating the catabolic and inflammatory response in allergic asthma. A number of single nucleotide polymorphisms that influence IL-18 production are found in the gene promoter region.
