NCT06325618

Brief Summary

100 women with karyotype verified TS, previously examined at 4 study visits during a 19-year period will be asked to participate in a 5th study visit. Healthy age-matched females will be included as controls in a ratio 2:1. The aim is to examine and quantify the cardiovascular and lymphatic system in women with TS. The investigators will study a possible causal mechanism between the known pathologic phenotype and alterations in these systems to understand, prevent or treat the life-threatening complications in TS.

Outcome Measures

Primary Outcomes (3)

  • Grade dysfunction of clinical and subclinical lymphedema using Indocyanine Green Lymphography and Magnetic Resonance Lymphangiography.

    Lymphedema will be graded in a total score according to the International Society of Lymphology. The stages are: Stage 0: Subclinical lymphedema. • Stage 1: Early, reversible pitting edema. Stage 2: Irreversible lymphedema. Stage 3: End-stage lymphedema.

    3 year

  • Detecting low-grade inflammation in Turner Syndrome preforming FDG-PET/CT-scans to locate low grade inflammation.

    3 years

  • Heat maps of the distribution of wall shear stress in the aorta

    Using 4D-flow analyses heat maps of the aorta will be made to illustrate the distribution of wall shear stress.

    3 years

Secondary Outcomes (5)

  • MRI evaluation and description of vascular abnormalities in Turner Syndrome

    3 years

  • Cardiac MRI to evaluate function

    3 years

  • Cardiac MRI to evaluate fibrosis of the myocardium

    3 years

  • Mapping DNA-methylations patterns in multiple tissues

    3 years

  • Immunologic changes in Turner Syndrome

    3 years
