The relationship between maternal postpartum psychological state and breast milk secretory immunoglobulin A level.

Background: Maternal psychological state may influence the passive transfer of immune factors (e.g., immunoglobulin) via the mother's breast milk.

Changes in maternal secretory immunoglobulin a levels in human milk during 12 weeks after parturition.

Background: Immune factors in human milk change in concentration after delivery. However, this concentration change during the early postpartum period has not yet been investigated in detail.

Methods: We measured Secretory IgA (SIgA) levels in the human milk of 91 postpartum mothers (after vaginal delivery) by using an enzyme immunoassay, in postpartum day 3, and weeks 1, 2, 3, 4, 8, and 12.

Association between stress-related substances in saliva and immune substances in breast milk in puerperae.

Objective: We examined the association between biochemical parameters of stress in puerperae and immune substances in breast milk.

Methods: The participants were 22 mothers 2 weeks after delivery, with normal pregnancy/delivery and a normal puerperal course. We measured the levels of secretory immunoglobulin A (SIgA) and cortisol in saliva and the level of SIgA and the leukocyte count in breast milk and investigated their association.
