Features of hormonal homeostasis in women with functional hypothalamic amenorrhea and premature ovarian insufficiengy caused by posttraumatic stress disorder.

Posttraumatic stress disorder can cause severe and prolonged amenorrhea in women. Since the beginning of the war in Ukraine, there has been an increased number of visits for the medical care of female military servicewomen and displaced women with this problem.The objective: to perform a comprehensive study of the characteristics of the hormonal levels of the hypothalamic-pituitary-ovarian axis and the stress hormone cortisol, as well as to analyze the presence of autoantibodies to ovarian tissue in women with secondary amenorrhea caused by posttraumatic stress disorder.Materials and methods. The levels of hypothalamic-pituitary-ovarian hormones (follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, estradiol, progesterone, free testosterone and anti-Mullerian hormone (AMH), as well as cortisol (urine), autoantibodies to ovarian tissue from 54 military servicewomen and displaced women with amenorrhea caused by posttraumatic stress disorder (main group). 35 (64.8%) women (the 1st subgroup) were diagnosed with functional hypothalamic amenorrhea (FHA), 19 (35.2%) patients (the 2nd subgroup) were diagnosed with premature ovarian failure (POF).The control group included 23 women of reproductive age (18–37 years), who were in a state of psychological comfort and had no menstrual cycle disorders.Results. As a result of the study, a significant (p<0.05) decrease of all pituitary-ovarian hormones was found in women with FHA, except for free testosterone and AMH. In patients with POF, there was an increased concentration of pituitary hormones and a decreased amount of estradiol by 2.2 times, progesterone by 3.9 times, and AMH by 21.0 times compared to the control group.A 1.5-fold increase in prolactin level in patients with POF compared to the indicator of the control group is noteworthy. The presence of autoantibodies in the group with POF was detected in 26.3% of cases (in the group of women with FHA – only in 2.9% of cases; p<0.05), which may be a manifestation of polyglandular autoimmune syndrome.In both examined subgroups of the main group, a probable increased cortisol concentration in daily urine was determined (by 2.0 times in the 1st subgroup and by 2.1 times in the 2nd subgroup compared to the control), which indicates a stressogenic dysfunction of the adrenal glands.Conclusions. Posttraumatic stress disorder can have an irreversible pathological effect on the reproductive system of women. In women with stressogenic functional hypothalamic amenorrhea there is a deep depression of the hypothalamic-pituitary-ovarian axis with preserving the follicular ovarian apparatus.In women with premature ovarian failure (POF) with long-term stress, there is a sharp depletion of the ovarian reserve. The presence of autoantibodies to ovarian tissue indicates the involvement of the immune system in the pathogenetic chain of development of amenorrhea, the severity of the lesion and the higher speed of the follicle atresia process by POF.
