Key result
Plasma protein levels increased during pregnancy or oral contraceptive use normalized within 6 weeks of delivery and 4 weeks of withdrawal.
Why the study?
Does parturition or withdrawal of oral contraceptives lead to normalization of plasma protein levels?
Observational
Does parturition or withdrawal of oral contraceptives lead to normalization of plasma protein levels?
Plasma protein levels elevated during pregnancy or oral contraceptive use normalize within 4 to 6 weeks after delivery or discontinuation.
The increased levels of α1-antitrypsin, TBG, cerculoplasmin, plasminogen, transferrin, hemopexin, β1C-globulin and β-lipoprotein found on use of contra ceptive estrogens or in pregnancy are normalized within 6 weeks of delivery and 4 weeks of withdrawal of the oral contraceptives. The changes of the ceruloplasmin and α1-antitrypsin do not run parallel to those other acute phase reactants in the early puerperal period.

Laurell et al. (1970) conducted an observational in Postpartum or withdrawal of oral contraceptives. Parturition and withdrawal of oral contraceptives was evaluated on Normalization of plasma protein levels. Plasma protein levels increased during pregnancy or oral contraceptive use normalized within 6 weeks of delivery and 4 weeks of withdrawal.
