Poor post natal mental health impacts mother, child immunity

A new research by Cedars-Sinai investigators published in the American Journal of Reproductive Immunology suggests mothers with prolonged mental health problems up to three years after childbirth could be suffering from irregularities in their immune system responses.

What are the symptoms of post natal mental disorders?

“We found that women who had clinically elevated symptoms of depression, anxiety, and/or post-traumatic stress disorder (PTSD) two to three years after delivery had genetic evidence of a higher prevalence of immune system defense mechanism activation,”said Eynav Accortt, PhD, principal investigator of the study and director of the Reproductive Psychology Program at Cedars-Sinai.

Accortt, who is also a clinical psychologist said “These women also appeared to have a reduction in the activity of genes related to antiviral immune responses that can offer the body protection from pathogens,”

How does poor mental health after childbirth affect immunity in mothers?

According to the Centers for Disease Control and Prevention, nearly 1 in every 8 women experience significant symptoms of perinatal mood and anxiety disorders that can adversely affect their overall health, daily activities and family life. Much of the research into maternal mental health to date has focused on the perinatal period and the first year after childbirth.

The investigators at Cedars-Sinai surveyed 33 women about their mental health over a period of two to three years after giving birth. The Study included the bioinformatic analyses of the participants’s blood samples for differential gene expression.

“Delayed or persistent postpartum anxiety, depression and PTSD is an area that is woefully understudied,” said Sarah Kilpatrick, MD, PhD, chair of the Department of Obstetrics and Gynecology at Cedars-Sinai and one of the study’s co-authors.

“In this preliminary research, we have identified genetic differences related to inflammation when comparing women experiencing prolonged symptoms of mood and anxiety disorders to those who did not report poor mental health. Additional studies will be needed for a deeper dive into the role inflammation may play in postpartum mental illness,” said Kilpatrick.

A primary goal of this work is to design a blood test that would detect which women are at the highest risk for serious and prolonged postpartum mood disorders, according to Accortt.

“A blood test could help us develop early interventions that provide medical and mental health treatments and support. We want to figure out why some women are at greater risk for depression, anxiety and PTSD. No one should have to suffer for years after childbirth,” said Accortt.

Jennifer Nicoloro-SantaBarbara, PhD, currently an investigator and instructor in the Department of Psychiatry at Harvard Medical School, is first author on the publication.
