[Urinary kallikrein levels during pregnancy]

Area of Science:

• Obstetrics and Gynecology
• Biochemistry
• Maternal-Fetal Medicine

Context:

• Gestosis, a pregnancy complication, poses risks including hypertension.
• Early prediction of gestosis is crucial for maternal and fetal well-being.
• Urinary kallikrein (UKK) is a biomarker under investigation for its role in pregnancy complications.

Purpose:

• To evaluate the diagnostic value of urinary kallikrein (UKK) levels in the second trimester for predicting gestosis, especially hypertensive gestosis.
• To compare UKK levels between normal pregnancies, pregnancies with gestosis, and those with other complications.

Summary:

• UKK levels naturally rise during early pregnancy, peaking in the first to second trimester.
• Significantly lower UKK levels were observed in women with gestosis, particularly the hypertensive type (p < 0.001).
• A subset of women (9.8%) with normal blood pressure but extremely low UKK levels were identified as potentially high-risk for gestosis.

Impact:

• UKK measurement shows promise as a predictive factor for hypertensive gestosis.
• This research supports the potential use of UKK in risk stratification for pregnancy-induced hypertension.
• Further detailed studies are ongoing to refine the predictive capabilities of UKK.
