LC-MS / MS Adrenal Steroids Assayed on Dried Blot Spot for the Congenital Adrenal Hyperplasia Neonatal Screening (SPECTROSPOT)

This research uses the Liquid Chromatography coupled to tandem Mass Spectrometry (LC-MS / MS) technique on dried blot spot samples for the neonatal screening of congenital adrenal hyperplasia.

The main objective of this study is to demonstrate that this technique allow dosage of adrenal steroids on dried blot spot samples as efficiently and with the same sensitivity than the current technic on a cohort of 132 newborns aged 2 to 5 days, with a gestational age greater than or equal to 30 weeks of amenorrhea.

Treatment and study plan

Primary outcomes

  1. Intra-class correlation coefficient between the values of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term in neonates aged from 48 to 120 hours of life

    Time frame: 15 months

    Intra-class correlation coefficient between the values of 21 Deoxycortisol (21DF), 17hydroxyprogesterone (17OHP), pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term in neonates aged from 48 to 120 hours of life

Secondary outcomes

  1. Study the difference between the levels of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates according to the term of birth (weeks)

    Time frame: 15 months

    Study the difference between the levels 21DF, 17OHP, pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the term of birth (weeks)

  2. Study the difference between the levels of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates of life according to the mode of delivery (low or Caesarean section before work)

    Time frame: 15 months

    Study the difference between the levels 21DF, 17OHP, pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the mode of delivery (low or Caesarean section before work)

  3. Study the difference between the levels of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates according to the presence or not of a corticotherapy antenatal.

    Time frame: 15 months

    Study the difference between the levels 21DF, 17OHP, pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the presence or not of a corticotherapy antenatal.

  4. Study the difference between the levels of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the presence or not of non-maternal-fetal infection

    Time frame: 15 months

    Study the difference between the levels 21DF, 17OHP, pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the presence or not of non-maternal-fetal infection (chorioamnionitis, neonatal infection at the time of screening)

  5. Study the difference between the levels of steroids assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the presence or not of newborn stress.

    Time frame: 15 months

    Study the difference between the levels 21DF, 17OHP, pregnenolone, 17hydroxypregnenolone and cortisol assayed by LC-MS / MS on dried blood spot and serum of preterm infants and full-term neonates aged from 48 to 120 hours of life according to the presence or not of newborn stress (septic shock and/or hypovolemic shock).
