Overview
Peripartum mood disturbances are mainly the mood alterations or changes seen in the women during and after the delivery. It involes the complex pathophysiology which is regulated by expression of different genes and neuroendocrine hormones. The gens playing important role are mainly Estrogen receptor alpha gene Polymorphisms in the serotonin transporter gene, 5-HTTgene encoding for MAOA and the gene encoding for Catechol-O-methyltransferase (COMT), Genetic variants for the TPH2 gene, SNP in OXT; SNP in the OXTR gene and methylation state was detected in association with postpartum depression. Hemicentin 1 gene (HMNC1) along with the neuroendocrine hormones maily GABA, Glutamate, serotonin and , or dopamine.
Pathophysiology
Pathophysiology Of Peripartum mood disturbances- Pathophysiology of Peripartum mood disturbances includes the role of various genes and hormones as described below
- Genetic Mechanism of postpartum depression: [1]Numerous gene playing significant role in deciding the pathophysiology are:
- Estrogen receptor alpha gene[2]
- Polymorphisms in the serotonin transporter gene,[3]
- 5-HTT
- gene encoding for MAOA[4]
- gene encoding for Catechol-O-methyltransferase (COMT)[5],
- Genetic variants for the TPH2 gene,
- SNP in OXT; SNP in the OXTR gene and methylation state was detected in association with postpartum depression.
- Hemicentin 1 gene (HMNC1) and its association with postpartum depression.
- Epigenetic mechanisms of postpartum depression
- In women with postpartum depression, there was a substantial interaction between OXTR DNA methylation, estradiol, and the ratio of allopregnanolone to progesterone.Alterations in DNA methylation of the OXTR gene are adversely linked with blood estradiol levels in women with postpartum depression.
- As a result, epigenetic alterations can affect metabolic processes linked to postpartum depression.
- Neuroendocrine mechanisms of postpartum depression:
- In postpartum depression, there is an interaction between the Hypothalamus-pituitary-gonadal (HPG) and Hypothalamus-Pituitary-Adrenal(HPA) axis.
- HPA axis function has been found to be influenced by reproductive hormones and vice versa.[6]
- As a result, any change in reproductive hormones may cause stress hormone levels to fluctuate, resulting in postpartum depression.
- Alterations of the HPA axis' function may also affect reproductive hormone levels, contributing to postpartum depression.
| GABA | Glutamate | Serotonin | Dopamine |
|---|---|---|---|
| GABA which is an inhibitory neurotransmitter in the brain | Glutamate is the excitatory neurotransmitter in the brain | Serotonin to 5HT1A receptors is decreased in the following brain regions | Mutations in DR1 |
| Level is inversely related with the depression symptoms in the postpartum period | postpartum depression its level are increased in the medial prefrontal cortex | mesiotemporal and anterior cingulate cortices. | Relates to the attention and affection of mother for the baby |
| In postpartum depression decreased in the dorsolateral prefrontal cortex. |
- Neuroinflammatory mechanisms in postpartum depression:
There is a negative relationship between T-cell number and postpartum depression symptoms, whereas IL-6 and IL-1β have a significant positive relationship with it.
- It is thought that in postpartum psychosis, immunoneuroendocrine set point is dysregulated with overactivation of the immune system's macrophage and monocyte arm. [7]
