NCT04189406

Brief Summary

Rationale: Due to accelerated germ cell loss, infertility is a major problem in girls with Turner syndrome (TS). Therefore, cryopreservation of ovarian tissue or oocytes before exhaustion of the ovarian reserve may preserve fertility in patients with TS. However, in the majority of females with TS , the ovarian reserve is exhausted before the age of menarche. Early markers indicating and predicting the ovarian reserve are necessary. During mid-childhood the hypothalamic-pituitary-gonadal (HPG) axis is quiescent and gonadotropins are usually unmeasurable. Nonetheless, this axis is active during infancy. Therefore, gonadotropins are measurable with peak values at 3 months of age and with lower (but still measurable) values at 9 months of age, in a period called the minipuberty. The aim of this study is to find markers of ovarian capacity, during the minipuberty, in order to predict ovarian reserve in the future. Objective: The hormonal range of LH, FSH, AMH, inhibin B, testosterone and estradiol in girls with TS during the minipuberty and the relation of the hormone serum levels with the karyotype. Study design: A prospective, cohort study with a duration of 3 years. Study population: Girls with a pre- or perinatal diagnosis TS who are born in a medical centre in the Netherlands during the duration of the study Main study parameters/endpoints: Serum levels of FSH, LH, AMH, inhibin B, testosterone and estradiol at the age of 3 and 9 months.

Study Arms (1)

Girls with Turner syndrome

Girls with a pre- or perinatal diagnosis TS who are born in a medical centre in the Netherlands during the duration of the study. The subjects will have an extra venapuncture of 3.5 mL blood at 3 and 9 months.

Other: Venapunction

Interventions

A blood sample of 3.5 mL (0.2 mL serum for FSH and LH, 0.15 mL serum for E2, 0.15 mL serum for T, 0.15 mL serum for AMH and 0.25 mL serum for Inhibin B) will be collected of all girls with TS at 3 months and 9 months of age. For the girls with TS, this will be collected with an extra venapuncture during a regular outpatient visit within the usual care.

Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

We include girls with the diagnosis TS before the age of 3 months based on full or partial absence of one X-chromosome or a mosaic pattern. We will recruit the girls with TS from all medical centres in the Netherlands. The control group consists of girls who have blood collected at 3 months and at 9 months of age for another indication. Participants in the control group will be recruited in the Radboudumc in Nijmegen.

You may qualify if:

  • In order to be eligible to participate in the TS group of this study, a subject must meet all of the following criteria:
  • A diagnosis of TS before the age of three months;
  • Girls with a diagnosis of classic TS or other variants (i.e. 45,X, 45,X/46XiXq, 45,X/46,XY, 45,X/46,XX, 45,X/47,XXX, 45,X/46,X,r(X), 46,XiXq, other);
  • Whose parents have agreed to participate in the study through a signed written informed consent form.
  • In order to be eligible to participate in the control group of this study, a subject must meet all of the following criteria:
  • No diagnosis of TS or any other diagnosis that might affect the HPG axis;
  • Girls that will have a blood collection within their usual care at 3 months and at 9 months of age.
  • Whose parents have agreed to participate in the study through a signed informed consent form.

You may not qualify if:

  • A potential subject who meets any of the following criteria will be excluded from participation in this study:
  • Any other diagnosis besides TS that might affect the HPG axis;
  • Ovarian surgery in the medical history;
  • Critical illness;
  • The use of medication affecting the HPG axis (e.g. estrogen suppletion therapy)
