Uitspraak van een “ex-prematuur”

  • “Het is geen ziekte om te vroeg geboren te zijn, maar het is niet zomaar iets.”


Incidence of very preterm birth

CBS-gegevens


Very preterm birth and in-hospital mortality

CBS-gegevens


Changed characteristics over time of very preterm populations


POPS

  • Project On Preterm and Small-for-gestational-age infants cohort:

    • 94% of all liveborns in the Netherlands in 1983 with:

      • gestational age <32 weeks and/or

      • birth weight <1,500 g

GR R23K polymorphism, very preterm birth and metabolic profile at 19 y

Finken, et al. (JCEM 2007)


Long-term effects in animals of antenatal glucocorticoid treatment

  • Raised blood pressure

  • Hyperglycemia

  • Renal morphology and function:

    • Smaller kidneys with less glomeruli

    • Lower GFR


Short-term benefits of antenatal glucocorticoid treatment

Roberts & Dalziel (Cochrane Datab Syst Rev 2006)


Short-term benefits of antenatal glucocorticoid treatment

  • Higher glucose and insulin levels in cord blood

  • Less often inotropic support

Verhaeghe, et al. (JCEM 2005); Moise, et al. (Pediatrics 1995)


Long-term effects of antenatal glucocorticoid treatment


GR N363S polymorphism, very preterm birth and waist circumference at 19 y

Finken, et al. (in preparation)


Conclusions (1)

  • Preterm infants have a metabolic profile similar to that of children born SGA

  • Preterm infants with neonatal growth retardation display a growth pattern similar to that of children born SGA

  • At present, there is no trial data available suggesting a beneficial effect of rhGH therapy in short children born very preterm who had experienced neonatal growth retardation


Conclusions (2)

  • Activation of the HPA axis may contribute to adverse metabolic health after preterm birth

  • The GR R23K variant, associated with decreased sensitivity to glucocorticoids, protects against postnatal growth failure and insulin resistance after very preterm birth

  • The GR N363S variant, associated with increased sensitivity to glucocorticoids, predisposes to adverse body composition after perinatal glucocorticoid treatment in indivduals born very preterm


Recommendations

  • Children born very preterm and SGA or experiencing neonatal growth retardation should be flagged

  • Body composition should be monitored throughout childhood

  • Waist circumference is a more valuable tool than BMI for determination of body fatness
