This study quantitatively measured glycogen levels in venous blood and various uterine tissues, including the endometrium, myometrium, cervix, and tumor tissue, from 135 women undergoing gynecologic surgery. The cohort included patients with uterine myoma, endometriosis, a combination of both conditions, and a healthy control group, with comparisons adjusted for parity, glucose tolerance, and menopausal status. Key findings indicated that women with endometriosis exhibited significantly higher blood glycogen levels but decreased glycogen in the myometrium, while cervical tissue showed elevated glycogen regardless of ovarian function or menopause. Endometrial glycogen content was also significantly higher in pathological cases compared to healthy tissue, although it did not vary cyclically within the same groups. Relevance to endometriosis: listed as one indication for GnRH antagonists, though the paper's main focus is uterine fibroids.

Abstract

The amount of glycogen in venous blood and uterine tissue from 135 women undergoing gynecologic surgery was quantitatively determined. One group had myoma (n = 48), another endometriosis (n = 30). 18 women had myoma combined with endometriosis of the myometrium. 39 women served as control group. The following samples of the uterus were obtained immediately after removal: endometrium, myometrium, cervix and "tumour". The glycogen content in pathological cases was compared to normal tissue of comparative endocrine state, parity status and glucose tolerance. The significance levels were determined by standard analysis of variance and "t" tests. In the group with endometriosis, a significant difference occurred in the amount of blood glycogen, while a significant decrease was observed in the myometrial tissue. The cervical tissue glycogen levels of patients with myoma or endometriosis were significantly higher and did not exhibit cyclic or menopausal changes. There were no significant cyclic differences in the amount of endometrial tissue glycogen in women with myoma or endometriosis. In these cases the glycogen content was significantly higher than in healthy endometrial tissue. Blood glucose and plasma insulin levels were found to be in a normal spectrum. Pathological glucose tolerance and parity status showed no correlation to the variation of uterine tissue glycogen.

Zusammenfassung Bei 135 Frauen wurde nach Hysterektomie Glykogen quantitativ im Myometrium, Endometrium, der Cervix uteri sowie im Tumorgewebe bestimmt. Die Befunde bei Uterus myomatosus (n=48), Uterus myomatosus und Endometriose (n=18) sowie ausschließlich Endometriosis interna (n=30) wurden mit denen bei histologisch unauffälligem Uterus (n=39) verglichen. Ergänzend wurde Glucose und Seruminsulin im Nüchternblut bestimmt. Menopause, Zyklusphase, Paritätstatus, pathologische Glucosetoleranz wurden als klinische Parameter bei der statistischen Auswertung der gewonnenen Daten berücksichtigt. Signifikant höhere Blutglykogenspiegel finden sich bei Endometriose unter Ovarialfunktion. Im Myometrium sind dagegen die Glykogenspiegel signifikant niedriger. Bei Myom oder Endometriose finden sich zudem höhere Glykogenkonzentrationen in der Cervix uteri sowohl unter Ovarialfunktion als auch in der Menopause. Gleich hohe Glykogenspiegel ließen sich im Endometrium der ersten und zweiten Zyklusphase bei Uterus myomatosus und bei Endometriose nachweisen. Der Glykogengehalt ist dabei signifikant größer als der im Endometrium des morphologisch unauffälligen Uterus. Die Blutglucose- und Seruminsulinwerte liegen im Normbereich. Pathologische Glucosetoleranz und häufige Schwangerschaften hatten keinen Einfluß auf die Glykogenspiegel im Gewebe.
