Autoimmune diseases show gender preferences in their pathogenesis and predominantly affect females of childbearing age. This clearly demonstrates the importance of hormones in controlling the immune response and their vital role in autoimmunity. Periods of hormonal fluctuation(like pregnancy and the menstrual cycle) in levels of reproductive hormones may have a profound effect on immune processes and health.
In this review paper, I will analyze the effect of hormonal dynamics during the menstrual cycle and pregnancy on the process of regulating the immune system and the progress of autoimmune disorders such as systemic lupus erythematosus, multiple sclerosis, and rheumatoid arthritis. The relevant publications were collected with the help of PubMed and were chosen according to their relevance and timeliness.
Several studies indicate that the hormones estrogen and progesterone are necessary in regulating the immune system through dose-dependent mechanisms. In the menstrual cycle, fluctuating hormone levels can lead to inflammatory response variations, as well as increased severity of autoimmunity conditions during different cycles such as the menstruation and the late luteal phases. The pregnancy phase is immunologically distinctive due to high immune tolerance; therefore, there is low disease activity in multiple sclerosis and rheumatoid arthritis, although it is not consistent for systemic lupus erythematosus. Postpartum states often imply high disease activity due to sudden hormone reduction and immune stimulation.
To conclude, this research supports the importance of hormonal regulation on immune response and autoimmunity onset. This knowledge may facilitate better treatment and further research on hormone treatments.
