Histological and immunohistological (monoclonal antibodies against desmin, vimentin, glycodelin, IGFBP-1, estrogen receptors and progesterone receptors) studies were carried out to examine uterine scrapes from 47 healthy women - medical abortions from 6 to 10 weeks of conception and from 44 patients after non-developing pregnancy in the first trimester (recurrent miscarriage), which had been induced by verified endocrine disorders. Among them, three isolated pathogenetic types were identified: 1) uterine gland retardation as preserved islets of cylindrical glands with a narrow lumen or, on the contrary, areas with enlarged glands and atrophic epitheliocytes; immunohistochemically, they exhibited a drastic reduction in the expression of glycodelin, the major local immunosuppressor; 2) incomplete decidualization when it in the presence of progesterone deficiency was delayed at the state of predecidual and decidual cells retaining the smooth muscle cell marker - desmin; 3) verified progesterone receptor insufficiency. Each of the given clinical and morphological types of endocrine causes of non-developing pregnancy requires that an individual approach be applied to examining and treating these patients. |
