Невынашивание беременности у больных хроническим эндометритом с недостаточностью лютеиновой фазы. Принципы терапии и профилактики

Abstract

Permanent inflammation of the endometrium against the background of altered vaginal microbiota is accompanied by a violation of cyclic tissue changes. The revealed deficiency of the secretory phase of the cycle was formed independently of the synthesis of progesterone by the corpus luteum and led to impaired embryo implantation and miscarriage. Objective. To evaluate the efficiency of dydrogesterone in miscarriage in patients with chronic endometritis (CE) with luteal phase deficiency. Patients and methods. The study involved 127 women aged 25 to 40 years non-pregnant and during pregnancy with biopsyverified deficiency of the luteal phase of the cycle and CE of varying degrees of activity according to immunohistochemistry data. Women from group 1 (n = 83) continuously received dydrogesterone in a cyclic regimen from the moment of diagnosis until the 21st week of pregnancy; women from group 2 (n = 44) received dydrogesterone for 4 months of CE treatment, then it was discontinued and resumed again from the onset of pregnancy until the 21st week. Conclusion. There was no normalization of the structure of the endometrium after CE treatment with dydrogesterone removal from therapy in women with miscarriage and deficiency of the luteal phase of the cycle. Administration of dydrogesterone in a cyclic regimen with pregravid preparation before pregnancy, regardless of the initial level of progesterone in the blood, by women with miscarriage, CE and luteal phase deficiency contributes to normalization of morphological state of the endometrium in most patients, to significant decrease in the frequency of early miscarriage and duration of in-patient treatment, in contrast to women who canceled dydrogesterone. Key words: dydrogesterone, luteal phase deficiency, recurrent miscarriage, chronic endometritis
