Multiparametric Assessment of Maternal Vascular Function in the Prediction of Hypertensive Disorders of Pregnancy

The present study is a single-centre prospective study that will enrol pregnant women during their first trimester of pregnancy (11+0 - 13+6 weeks of gestation).

During pregnancy, women will undergo standard clinical evaluation and management. During the two study visits (enrollment and 24+0 - 27+6 weeks of gestation) the investigators will perform arterial tonometry (Pulsepen) and in vivo darkfield microscopy (Glycocheck) to evaluate endothelial and vascular function. A urine sample and a blood sample for specific study analyses on metabolic profile, endothelial and angiogenic markers will be collected. Pregnancy outcomes will be collected at delivery and five years after delivery all the participants will be interview to collect long-term cardiovascular outcomes. Serum endothelial and angiogenic markers will be evaluated only in participants who will develop hypertensive disorders of pregnancy and in an equal number of controls matched for age and body mass index at the time of conception.

About this study

Primary aim:

To determine the role of the combination of arterial tonometry and endothelial glycocalyx measurement in predicting the risk of developing hypertensive disorders in pregnancy.

Secondary aims:

  • To determine the association between circulating markers of angiogenesis and endothelial dysfunction (ANG-1, ANG-2, ET-1, ICAM-1 and VCAM-1) and the development of hypertensive disorders of pregnancy.
  • To define the trends of serum uric acid, lipids and xanthine oxidase activity in normotensive and hypertensive pregnancies.
  • To determine the ability of the combination of arterial tonometry and endothelial glycocalyx measurement, performed in the two study visits during pregnancy, in predicting the risk of long-term maternal cardiovascular disease.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age greater than or equal to 18 years
  • Single pregnancy
  • No previous pregnancies lasting more than 12 weeks
  • Participant willing and able to give informed consent for participation in the study

Exclusion criteria

  • Intermediate-high risk of genetic abnormalities and/or need to perform invasive tests (amniocentesis, villocentesis)
  • History of solid organ or hematopoietic stem cell transplantation
  • Chronic renal failure (eGFR≤45ml/min/1.73m2)
  • Chronic treatment with antihypertensive drugs and/or xanthine oxidase (XO) inhibitors

Treatment and study plan

Arterial applanation tonometry

Device

Arterial applanation tonometry will be performed at the carotid and femoral level by the PulsePen device (Software WPulsePen version 2.3.1, DiaTecne, Milan, Italy), while the subject is lying in the horizontal position and after 5 minutes of rest.

Other names: PulsePen, Arterial stiffness measurement, Pulse wave velocity assessment

In vivo endothelial glycocalyx measurement

Device

The in vivo microscopy (GlycoCheck system) is performed in the sublingual capillaries during the morning, with the participant sitting on a chair. The sublingual capillaries are visualized using an SDF video microscope (Capiscope handheld, KK Research technology Ltd).

Other names: Glycocheck, Sidestream dark field microscopy

Serum markers of angiogenesis and endothelial dysfunction

Diagnostic Test

ELISA assays to measure serum circulating markers of angiogenesis and endothelial dysfunction (ANG-1, ANG-2, ET-1, ICAM-1 and VCAM-1).

Other names: ANG-1, ET-1, ICAM-1, VCAM-1, ANG-2

Blood chemistry test

Diagnostic Test

Immunochemistry analysis of serum levels of uric acid, total cholesterol, LDL-cholesterol, HDL-cholesterol, Triglycerides, Lipoprotein (a)

Serum xanthine oxidase activity

Diagnostic Test

Serum xanthine oxidase (XO) activity will be assessed in blood samples measuring the ability of XO to produce uric acid
