Abstract

Background:Some reports have suggested that decreased nitric oxide metabolites(NOx) and activity of nitric oxide synthase could be related to the pathophysiology of depression. We evaluated plasma levels of NOx in pregnant women with and without postpartum depression at prenatal and postnatal period.
methods:The plasma concentrations of NOx were measured in 104 pregnant women in the third trimester and at 6 weeks postpartum and in 64 normal controls. The severity of depression and anxiety was measured with the Edinburgh Postnatal Depression Scale(EPDS), Beck Depression Inventory(BDI), and Beck Anxiety Scale(BAI).
Results:Plasma NOx levels at 6 weeks postpartum were significantly lower in cases of postpartum major depression(EDPS scores > or = 13 points) than in cases without depression(EDPS scores < or = 9 points). Plasma NOx levels had significantly negative correlation with EPDS scores at 6 weeks postpartum.
Conclusions:We demonstrate that decreased plasma NOx is associated with postpartum depression. Further studies are required to determine whether individual serum concentration of plasma NOx alone could predict maternal depression.
