promestriene and Vaginal-Diseases

Vaginal promestriene was tested in gynecological cancer patients who suffered from severe vaginal dryness and dyspareunia. This form of estrogen has a low level of vaginal absorption and proved to be effective for vaginal atrophy.. 17 patients were treated with a 10mg soft vaginal suppository daily for one month. Plasma levels of estrone sulfate (E1S), used as the marker of overall estrogenicity, were measured by liquid chromatography in combination with mass spectrometry.. Mean E1S levels changed from 533 (22-2920) to 374 (81-856) pg/ml (p=0.39).. In highly symptomatic gynecological cancer patients the level of circulating estrone sulfate was not significantly affected by vaginal promestriene treatment overall, but a wide range of levels was noted pre and post treatment in individual patients.

To determine whether the use of local Estrogen Replacement Therapy (ERT) affects the adequacy of colposcopic examination; to distinguish abnormal cervical smears secondary to hypoestrogenism from abnormal cervical smears due to true preneoplastic changes; and to suggest an effective management of atypical squamous cells of undeterminated significance (ASCUS) and low grade squamous intraepithelial lesion (L-SIL) in menopausal women.. Two-hundred fifty-four postmenopausal women with abnormal pap smears (L-SIL or ASCUS) underwent colposcopy and HPV DNA testing. All patients with positive colposcopy underwent punch biopsy, and all patients with positive histological findings underwent surgical treatment. Patients with negative colposcopy, both satisfactory [visible Squamo-Columnar Junction (SCJ)] and unsatisfactory, were treated with local estrogenic replacement therapy (ERT) for 3 months, and repeated colposcopy and pap smears. Patients with negative colposcopy and negative pap smears after ERT were included in a 6 months cytological and colposcopic follow-up. Patients with positive colposcopy underwent punch biopsy, if colposcopy was negative and cytology was positive, patients underwent endocervical curettage.. One-hundred ninety-five had a diagnosis of ASCUS and 59 a diagnosis of L-SIL. At the first colposcopy, 39 patients showed a lesion and had an appropriate treatment. One-hundred eighty-eight in the ASCUS group and 27 in the L-SIL group had a negative colposcopy and were treated with local ERT. At first colposcopic examination, 37 of the 215 negative colposcopies resulted satisfactory and 178 of the 215 resulted unsatisfactory. After local ERT, 130 of the 178 patients had a satisfactory follow-up colposcopy. After ERT, 25 patients of 215 with initial abnormal CVS and negative colposcopy, required appropriate treatment. After ERT, 190 patients of 215 showed negative colposcopy and at cytologic follow-up showed 23 ASCUS and 167 normal CVS.. A correct diagnosis and an efficient treatment seem to be obtained with a short-time ERT followed by a short-time cytological and colposcopic follow-up. With a single course of local ERT it may be possible to distinguish between benign CVS mimicking atrophy and true preneoplastic changes. Estrogen therapy will often cause enough ectropion of the endocervical cells so that the entire SCJ can be visualized. Moreover, it may reduce the number of endocervical curettage or loop excision or cone procedure for women with inadequate colposcopic examination.

Topical estrogen therapy is recommended for the treatment of vaginal atrophy. This study was designed to compare the uterotrophic effects of a new estrogen vaginal formulation (0.005% estriol vaginal gel) and other existing topical treatments (Ovestinon(®) and Colpotrofin(®)).. Each one of the studied formulations was administered intravaginally to groups of ovariectomized rats with cytologically confirmed vaginal atrophy. The doses were adjusted by animal weight according to human dosage. After daily treatment for 14days, the animals were sacrificed and their vaginas and uteri removed. All uteri were weighted. Uteri and vaginas were fixed for histological evaluation.. All three active formulations proved to be very effective in the cytological reversal of vaginal atrophy. However, they differ in their effects in the uteri. Ovestinon(®) and Colpotrofin(®) produced a significant increase in uterine weight, myometrial and endometrial thickness as well as histological modifications in the endometrium suggestive of estrogenic activity. Conversely, animals treated with 0.005% estriol vaginal gel, did not show significant weight increase or any other macroscopical or microcospical modifications of the uteri, an effect comparable to placebo.. There are significant differences in the uterotrophic effect of three different topical estrogen formulations as tested in a rat model of vaginal postmenopausal atrophy. While the three formulations were equally effective in reversing vaginal atrophy, only the newly developed ultra-low dose 0.005% estriol vaginal gel has proved to lack any significant estrogenic effect on the uterus.
