Management of dysfunctional uterine bleeding based on endometrial thickness.

OBJECTIVE: To manage patients with dysfunctional uterine bleeding (DUB) according to endometrial thickness. METHODS: A retrospective chart review of 49 patients who reported 8 or more days of bleeding was performed. They were then divided into three groups based on endometrial thickness (mm): less than 6, 6-11, and greater than 11. These three groups were treated with combined oral contraceptive pills (OCP), conjugated estrogen plus progesterone and megestrol respectively. Patients given megestrol also underwent endometrial biopsy before treatment. Patients recorded the degree of bleeding each day for one month after starting treatment. RESULTS: Mean endometrial thickness in the combined OCPs, conjugated estrogen plus progesterone and megestrol groups were 4, 8 and 14 mm, respectively. Combined OCPs decreased bleeding from 46 to 8 days (P < 0.05, n = 8). Conjugated estrogen plus progesterone decreased the number of days of bleeding from a mean of 41 to 9 (P < 0.01, n = 16). Megestrol decreased bleeding from 54 to 3 days (P < 0.001, n = 25). 52% of patients given megestrol had endometrial hyperplasia. CONCLUSION: These results support the effectiveness of treating patients with DUB according to endometrial thickness.

Type 2 11beta-hydroxysteroid dehydrogenase activity in human fallopian tube and correlation of enzyme levels with endometrial histopathology.

PROBLEM: The inter-conversion of hormonally active cortisol and inactive cortisone is catalyzed by 11beta-hydroxysteroid dehydrogenase (11beta-HSD). This conversion controls the level of active glucocorticoid concentration in tissues. As the fallopian tube plays a major role in the process of fertilization, we wanted to investigate whether 11beta-HSD is present in the human fallopian tube to control the glucocorticoid levels as in other tissues. METHOD OF STUDY: Isthmic, ampullary and fimbrial portions of the fallopian tube are obtained from patients undergoing hysterectomy and salpingo-oopherectomy for symptomatic leomyomata uteri. 11beta-HSD activities were measured in the homogenates of the tube, cortisol as the steroid substrate. The enzyme activity was expressed as nanomolar cortisone formed per minute per gram of tissue (mean +/- S.D.). RESULTS: A significant level of 11beta-HSD activity in oxidation direction was found in all three parts of the tube. There is no significant difference in the distribution of the enzyme activity throughout the tube. When tubal 11beta-HSD activity was compared with endometrial histology, the enzyme activity is significantly lower in proliferative endometrium when compared with secretory endometrium (P = 0.002). The enzyme activity in inactive endometrium is significantly higher than the active endometrium (P = 0.05). CONCLUSION: The presence of 11beta-HSD throughout the fallopian tube and its correlation to endometrial histology is indicative of its probable role in controlling the glucocorticoid levels in the tissue, which in turn may influence the fertilization process.
