Relationship between second-trimester amniotic fluid levels of Prokineticin-1 and Matrix Metalloproteinase-2 with adverse pregnancy outcome.

To investigate the levels of Prokineticin-1 (PROK1) and matrix metalloproteinase-2 (MMP-2) in second-trimester amniotic fluid (AF). AF samples were investigated in 81 patients. AF-PROK1 and AF-MMP-2 were not significantly associated with adverse pregnancy outcomes (preeclampsia, intrauterine growth retardation, spontaneous preterm birth, gestational diabetes, gestational hypertension). AF-PROK1 levels in patients with abnormal first-trimester screening were significantly higher than those who underwent amniocentesis due to abnormal second-trimester screening tests (p = .04). AF-PROK1 or AF-MMP-2 do not have a role in the prediction of adverse pregnancy outcomes.
