Kh. Schmeelk et al., Maternal depression and risk for postpartum complications: Role of prenatal corticotropin-releasing hormone and interleukin-1 receptor antagonist, BEHAV MED, 25(2), 1999, pp. 88-94
The pregnancies of 58 healthy adolescents (ages 13 to 19 years) were follow
ed to examine links between symptoms of depression, corticotropin-releasing
hormone (CRH), interleukin-1 beta, (IL-1 beta), and IL-1 receptor antagoni
st (IL-Ira) as possible predictors of maternal and infant outcomes. Materna
l psychological adjustment and medical complications during gestation, labo
r delivery, and the postpartum period were monitored. Plasma samples collec
ted during gestation were assayed for CRH, IL-1 beta, and IL-1ra. During ge
station, symptoms of maternal depression were found to be associated with l
ower levels of CRH; lower levels of CRH were associated with lower levels o
f IL-1ra. In addition, lower revels of IL-1ra predicted higher rates of mat
ernal complications after childbirth. IL-IP, detected in only 4 mothers, wa
s not associated with any predictor or outcome measures. During gestation,
CRH may induce circulating cytokine inhibitors without significantly affect
ing cytokine production or synthesis. Maternal symptoms of depression durin
g gestation may attenuate the association between CRH and IL-1ra.
