Progestogens or progestogen-releasing intrauterine systems for uterine fibroids (other than preoperative medical therapy).

BACKGROUND: Uterine fibroids can cause heavy menstrual bleeding. Medical treatments are considered to preserve fertility. It is unclear whether progestogens or progestogen-releasing intrauterine systems can reduce fibroid-related symptoms. This is the first update of a Cochrane Review published in 2013. OBJECTIVES: To determine the effectiveness of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, and PsycINFO databases to July 2020. We also searched trials registers for ongoing and registered trials, and checked references of relevant trials. SELECTION CRITERIA: All identified published or unpublished randomised controlled trials (RCTs) assessing the effect of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data, assessed risk of bias, and assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: This updated review included four studies with 221 women with uterine fibroids. The evidence was very low quality, downgraded for serious risk of bias, due to poor reporting of study methods, and serious imprecision. Levonorgestrel-releasing intrauterine device (LNG-IUS) versus hysterectomy There was no information on the outcomes of interest, including adverse events. LNG-IUS versus low dose combined oral contraceptive (COC) At 12 months, we are uncertain whether LNG-IUS reduced the percentage of abnormal uterine bleeding, measured with the alkaline hematin test (mean difference (MD) 77.50%, 95% confidence interval (CI) 70.44 to 84.56; 1 RCT, 44 women; very low-quality evidence), or the pictorial blood assessment chart (PBAC; MD 34.50%, 95% CI 11.59 to 57.41; 1 RCT, 44 women; very low-quality evidence); increased haemoglobin levels (MD 1.50 g/dL, 95% CI 0.85 to 2.15; 1 RCT, 44 women; very low-quality evidence), or reduced fibroid size more than COC (MD 1.90%, 95% CI -12.24 to 16.04; 1 RCT, 44 women; very low-quality evidence). The study did not measure adverse events. LNG-IUS versus oral progestogen (norethisterone acetate (NETA)) Compared to NETA, we are uncertain whether LNG-IUS reduced abnormal uterine bleeding more from baseline to six months (visual bleeding score; MD 23.75 points, 95% CI 1.26 to 46.24; 1 RCT, 45 women; very low-quality evidence); increased the percentage of change in haemoglobin from baseline to three months (MD 4.53%, 95% CI 1.46 to 7.60; 1 RCT, 48 women; very low-quality evidence), or from baseline to six months (MD 10.14%, 95% CI 5.57 to 14.71; 1 RCT, 45 women; very low-quality evidence). The study did not measure fibroid size. Spotting (adverse event) was more likely to be reported by women with the LNG-IUS (64.3%) than by those taking NETA (30%; 1 RCT, 45 women; very low-quality evidence). Oral progestogen (dienogest, desogestrel) versus goserelin acetate Compared to goserelin acetate, we are uncertain whether abnormal uterine bleeding was reduced at 12 weeks with dienogest (PBAC; MD 216.00 points, 95% CI 149.35 to 282.65; 1 RCT, 14 women; very low-quality evidence) or desogestrel (PBAC; MD 78.00 points, 95% CI 28.94 to 127.06; 1 RCT, 16 women; very low-quality evidence). Vasomotor symptoms (adverse events, e.g. hot flashes) are only associated with goserelin acetate (55%), not with dienogest (1 RCT, 14 women; very low-quality evidence) or with desogestrel (1 RCT, 16 women; very low-quality evidence). The study did not report fibroid size. AUTHORS' CONCLUSIONS: Because of very low-quality evidence, we are uncertain whether the LNG-IUS reduces abnormal uterine bleeding or increases haemoglobin levels in premenopausal women with uterine fibroids, compared to COC or norethisterone acetate. There was insufficient evidence to determine whether the LNG-IUS reduces the size of uterine fibroids compared to COC. We are uncertain whether oral progestogens reduce abnormal uterine bleeding as effectively as goserelin acetate, but women reported fewer adverse events, such as hot flashes.

Antiretroviral therapy and vaginally administered contraceptive hormones: a three-arm, pharmacokinetic study.

BACKGROUND: Drug-drug interactions between orally administered antiretroviral therapy (ART) and hormones released from an intravaginal ring are not known. We hypothesised that ART containing either efavirenz or ritonavir-boosted atazanavir would alter plasma concentrations of vaginally administered etonogestrel and ethinylestradiol but that ART concentrations would be unchanged during use of an intravaginal ring. METHODS: We did a parallel, three-group, pharmacokinetic evaluation at HIV clinics in Asia (two sites), South America (five), sub-Saharan Africa (three), and the USA (11) between Dec 30, 2014, and Sept 12, 2016. We enrolled women with HIV who were either ART-naive (control group; n=25), receiving efavirenz-based ART (n=25), or receiving atazanavir-ritonavir-based ART (n=24). Women receiving ART were required to be on the same regimen for at least 30 days, with 400 copies or less per mL of plasma HIV-1 RNA; women not receiving ART had CD4 counts of 350 cells per µL or less. We excluded participants who had a bilateral oophorectomy or conditions that were contraindicated in the intravaginal ring product labelling. An intravaginal ring releasing etonogestrel and ethinylestradiol was inserted at entry (day 0). Single plasma samples for hormone concentrations were collected on days 7, 14, and 21 after intravaginal ring insertion. The primary outcome was the plasma concentration of etonogestrel and ethinylestradiol on day 21. Etonogestrel and ethinylestradiol concentrations were compared between each ART group and the control group by geometric mean ratio (GMR) with 90% CIs and Wilcoxon rank-sum test. As secondary outcomes, efavirenz or ritonavir-boosted atazanavir concentrations were assessed by 8-h intensive pharmacokinetic sampling at entry before intravaginal ring insertion and before intravaginal ring removal on day 21. Antiretroviral areas under the concentration-time curve (AUC0-8 h) were compared before and after intravaginal ring insertion by GMR (90% CI) and Wilcoxon signed-rank test. This study is registered with ClinicalTrials.gov, number NCT01903031. FINDINGS: Between Dec 30, 2014, and Sept 12, 2016, we enrolled 84 participants in the study; ten participants were excluded from the primary hormone analysis. 74 participants met the primary endpoint: 25 in the control group, 25 in the efavirenz group, and 24 in the atazanavir group. On day 21 of intravaginal ring use, participants receiving efavirenz had 79% lower etonogestrel (GMR 0·21, 90% CI 0·16-0·28; p<0·0001) and 59% lower ethinylestradiol (0·41, 0·32-0·52; p<0·0001) concentrations compared with the control group. By contrast, participants receiving ritonavir-boosted atazanavir had 71% higher etonogestrel (1·71, 1·37-2·14; p<0·0001), yet 38% lower ethinylestradiol (0·62, 0·49-0·79; p=0·0037) compared with the control group. The AUC0-8 h of efavirenz or atazanavir did not differ between the groups. INTERPRETATION: Hormone exposure was significantly lower when an intravaginal ring contraceptive was combined with efavirenz-based ART. Further studies designed to examine pharmacodynamic endpoints, such as ovulation, when intravaginal ring hormones are combined with efavirenz are warranted.

Proandrogenic and Antiandrogenic Progestins in Transgender Youth: Differential Effects on Body Composition and Bone Metabolism.

Context: Progestins can be used to attenuate endogenous hormonal effects in late-pubertal transgender (trans) adolescents (Tanner stage B4/5 and G4/5). Currently, no data are available on the effects of progestins on the development of bone mass or body composition in trans youth. Objective: To study prospectively the evolution of body composition and bone mass in late-pubertal trans adolescents using the proandrogenic or antiandrogenic progestins lynestrenol (L) and cyproterone acetate (CA), respectively. Design and Outcome Measurements: Forty-four trans boys (Tanner B4/5) and 21 trans girls (Tanner G4/5) were treated with L or CA for 11.6 (4 to 40) and 10.6 (5 to 31) months, respectively. Anthropometry, grip strength, body composition, and bone mass, size, and density were determined by dual-energy X-ray absorptiometry and peripheral quantitative computed tomography before the start of progestin and before addition of cross-sex hormones. Results: Using L, lean mass [+3.2 kg (8.6%)] and grip strength [+3 kg (10.6%)] significantly increased, which coincided with a more masculine body shape in trans boys. Trans girls showed loss of lean mass [-2.2 kg (4.7%)], gain of fat mass [+1.5 kg (9.4%)], and decreased grip strength Z scores. CA limited normal bone expansion and impeded pubertal bone mass accrual, mostly at the lumbar spine [Z score: -0.765 to -1.145 (P = 0.002)]. L did not affect physiological bone development. Conclusion: Proandrogenic and antiandrogenic progestins induce body composition changes in line with the desired appearance within 1 year of treatment. Bone health, especially at the lumbar spine, is of concern in trans girls, as bone mass accrual is severely affected by androgen suppressive therapy.

Comparison of the efficacy of micronized progesterone and lynestrenol in treatment of simple endometrial hyperplasia without atypia.

PURPOSE: To evaluate the treatment of simple endometrial hyperplasia without atypia with different gestagens. METHODS: Sixty premenopausal women with histologically documented endometrial hyperplasia without atypia were included in this prospective controlled study. Patients were randomized into two groups: Group I included 30 patients who received lynestrenol (LYN) in a dose of 15 mg/d, while Group II included 30 patients who received micronized progesterone (MP) 200 mg/d for 12 days per cycle for 3 months. Patients were reevaluated with endometrial curettage after treatment. MP and LYN regimens were compared to regression, resolution or persistence rates and metabolic parameters. RESULTS: After 3 months of treatment in both groups, none of the cases progressed. In LYN group, the rate of resolution was observed to be higher compared to MP group (p = 0.045). LYN was found more effective inducing resolution in patients more than 45 years compared to MP (p = 0.036). When we compare both groups after 3 months of treatment, there was no statistically significant difference in BMI, total cholesterol, HDL, LDL and fibrinogen level between two groups. The rate of patients without any side effects was found to be similar in both groups (p = 0.5). CONCLUSION: LYN which is a synthetic progestin ensures better endometrial control compared to MP in simple hyperplasia without atypia in the patients of premenopausal age especially in ages more than 45 years.

Effect of eslicarbazepine acetate on the pharmacokinetics of a combined ethinylestradiol/levonorgestrel oral contraceptive in healthy women.

OBJECTIVE: To investigate the effect of once-daily (QD) eslicarbazepine acetate (ESL) 800 mg and 1,200 mg administration on pharmacokinetics of a combined ethinylestradiol/levonorgestrel oral contraceptive (OC) in women of childbearing potential. METHODS: Two two-way, crossover, two-period, randomized, open-label studies were performed in 20 healthy female subjects, each. In one period (ESL+OC period), subjects received ESL 800 mg QD in one study and ESL 1200 mg QD in the other study, for 15 days; concomitantly with the Day 14 ESL dose, an oral single dose of 30 µg ethinylestradiol and 150 µg levonorgestrel was administered. In the other period (OC alone), a single dose of 30 µg ethinylestradiol and 150 µg levonorgestrel was administered. Three weeks or more separated the periods. An analysis of variance (ANOVA) was used to test for differences between pharmacokinetic parameters of 30 µg ethinylestradiol and 150 µg levonorgestrel following ESL+OC and OC alone, and 90% confidence intervals (90%CI) for the ESL+OC/OC alone geometric mean ratio (GMR) were calculated. RESULTS: ESL significantly decreased the systemic exposure to both ethinylestradiol and levonorgestrel. GMR (90%CI) for AUC0-24 of ethinylestradiol were 68% (64%; 71%) following 1,200 mg ESL and 75% (71%; 79%) following 800 mg ESL. GMR (90%CI) for AUC0-24 of levonorgestrel were 76% (68%; 86%) following 1,200 mg ESL and 89% (82%; 97%) following 800 mg ESL. CONCLUSIONS: A clinically relevant dose-dependent effect of ESL administration on the pharmacokinetics of ethinylestradiol and levonorgestrel was observed. Therefore, to avoid inadvertent pregnancy, women of childbearing potential should use other adequate methods of contraception during treatment with ESL, and, in case ESL treatment is discontinued, until CYP3A4 activity returns to normal.

Progestogens or progestogen-releasing intrauterine systems for uterine fibroids.

BACKGROUND: Uterine fibroids are the most common premenopausal benign uterine tumours. Fibroids can cause symptoms including heavy menstrual bleeding, pelvic pressure and pain. Progestogens can be administered by various routes. Intramuscular injection of depot medroxyprogesterone acetate (DMPA) has dual actions (stimulatory or inhibitory) on fibroid cell growth. Progestogen-releasing intrauterine systems (IUS) decrease menstrual blood loss associated with fibroids by inducing endometrial atrophy and reduction of uterine fibroid size. Currently, their effectiveness for the treatment of uterine fibroids has not been evaluated. OBJECTIVES: To determine the effectiveness of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. SEARCH METHODS: We searched the Menstrual Disorders and Subfertility Group Specialised Register (inception to 17 August 2012), CENTRAL (inception to 17 August 2012) and Database of Abstracts of Reviews of Effects (DARE) in The Cochrane Library, MEDLINE (inception to 17 August 2012), Ovid EMBASE (1 January 2010 to 17 August 2012), Ovid PsycINFO (inception to 17 August 2012), CINAHL database, and trials registers for ongoing and registered trials. SELECTION CRITERIA: All identified published or unpublished randomised controlled trials (RCTs) assessing the effect of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. DATA COLLECTION AND ANALYSIS: We assessed all potentially eligible studies identified as a result of the search strategy. Two review authors extracted data from each included study using an agreed form and assessed the risk of bias. We resolved discrepancies through discussion. MAIN RESULTS: This review included three studies. However, data for progestogen-releasing intrauterine systems were available from only one study that compared 29 women with a levonorgestrel (LNG)-IUS versus 29 women with a combined oral contraceptive (COC) for treating uterine fibroids. There was a significant reduction of menstrual blood loss (MBL) in women receiving the LNG-IUS compared to the COC using the alkaline hematin test (mean difference (MD) 77.5%, 95% CI 71.3% to 83.67%, 58 women) and a pictorial assessment chart (PBAC) (MD 34.5%, 95% CI 14.9% to 54.1%, 58 women). The reduction in uterine fibroid size was significantly greater in the leuprorelin group at 16 weeks compared to the progestogen lynestrenol group (MD -15.93 mm, 95% CI -18.02 to -13.84 mm, 46 women). There was no RCT evaluating the effect of DMPA on uterine fibroids. AUTHORS' CONCLUSIONS: Progestogen-releasing intrauterine systems appear to reduce menstrual blood loss in premenopausal women with uterine fibroids. Oral progestogens did not reduce fibroid size or fibroid- related symptoms. However, there was a methodological limitation and the one included study with data had a small sample size. This evidence is insufficient to support the use of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids.

Lipid peroxidation in judoists using oral contraceptives.

12 female judoists using oral contraceptives (OCU) containing 0.03 mg ethinylestradiol and 3 mg drospirenone for 20 ± 12 months (mean ± SD) were compared with a control group of 14 judoist noncontraceptive users (NCU) in order to evaluate resting (T1) and postexercise (T2) lipid peroxidation (LPO) and antioxidant parameters. Data were collected 20 min before and 10 min after a morning session of judo training and included determination of lag phase (Lp) before free radical-induced oxidation, glutathione peroxidase (GPx), α-tocopherol, retinol, and oxidative stress markers related to LPO. Significantly higher resting oxidative stress (+125.8 and +165.2% for malondialdehyde and lipid peroxides, respectively) and lower values of Lp and GPx (-23.4 and -12.1%, respectively) were observed in the OCU compared with NCU. The judo training session induced an increase in plasma LPO whatever the treatment. We noted significant increases in Lp (+14.7%; p<0.05 vs. preexercise) and GPx (22.1%; p<0.05 vs. preexercise) only in the NCU group. We suggest that a judo training session favourably altered some antioxidants in NCU but not in OCU. As excessive oxidative stress is linked to the development of several chronic diseases, the use of agents to reduce antioxidants may be reasonable in OCU.

Differences in prescription rates and odds ratios of antidepressant drugs in relation to individual hormonal contraceptives: a nationwide population-based study with age-specific analyses.

OBJECTIVES: To examine, among young women, the association of individual hormonal contraceptives, within two broad groupings, with antidepressant therapy. METHODS: In a nationwide register-based study, we examined the prescription rates of antidepressant drugs in relation to individual combined hormonal and progestin-only contraceptives among Swedish women aged 16-31 years (N = 917,993). Drug data were obtained from the Swedish Prescribed Drug Register for the period 1 July 2005-30 June 2008. Data on the total population of women aged 16-31 in 2008 were obtained from the Total Population Register of Statistics Sweden. The proportion of women using both hormonal contraception and antidepressants, and odds ratios (ORs) for antidepressant use for hormonal contraceptive users versus non-users, were calculated, the latter by logistic regression, for each formulation. RESULTS: The highest antidepressant OR in all age groups, particularly in the 16-19 years age group, related to medroxyprogesterone-only, followed by etonogestrel-only, levonorgestrel-only and ethinylestradiol/norelgestromin formulations. Oral contraceptives containing ethinylestradiol combined with lynestrenol or drospirenone had considerably higher ORs than other pills. ORs significantly lower than 1 were observed when ethinylestradiol was combined with norethisterone, levonorgestrel or desogestrel. CONCLUSION: The association between use of hormonal contraceptives and antidepressant drugs varies considerably within both the combined hormonal contraceptive and the progestin-only groups.

Comparison of the efficacy of three progestins in the treatment of simple endometrial hyperplasia without atypia.

AIM: To evaluate the treatment of endometrial hyperplasia (EH) with different progestins. METHODS: Eighty-two women with simple EH without atypia were included. Patients were offered oral progestagens and were randomized to one of three options for 3 months: medroxyprogesterone acetate (MPA, 10 mg/day), lynestrenol (LYN, 15 mg/day) and norethisterone (NET, 15 mg/day) for 10 days per cycle. Patients were reevaluated after treatment. Women diagnosed with proliferative and nonatypical EH at the second curettage were offered the same progestins for another 3 months. The primary outcome of the study was the proportion of women requiring further treatment. RESULTS: Of the 82 women, 46 (56.1%) received MPA (23.2%), LYN (13.4%) and NET (19.5%) therapy for another 3 months at the end of the first 3 months of treatment. The patients receiving MPA showed resolution in 36.7% of the cases versus 37% in the NET group. The highest resolution rate (56%) was observed in the LYN group, although there was no statistically significant difference between progestins regarding the proportion of women requiring further treatment (χ(2) = 2.608; p = 0.271). CONCLUSION: It seems that the efficacies of oral progestins are similar at these dosages in simple EH without atypia.

Gene expression signatures of breast tissue before and after cross-sex hormone therapy in female-to-male transsexuals.

OBJECTIVE: To evaluate gene expression signatures of breast tissue in female-to-male (FtM) transsexuals under cross-sex hormone therapy (HT). DESIGN: Prospective cohort study. SETTING: Academic research institution. PATIENT(S): Five hormone-naïve FtM transsexuals before and after HT. INTERVENTION(S): Breast tissue biopsy before and after 2 years of intramuscular testosterone undecanoate (1,000 mg every 12 wk) and oral lynestrenole (5 mg daily), and gene signature analysis by global gene expression array covering 28,869 genes. MAIN OUTCOME MEASURE(S): Differential regulation of specific genes and gene expression signatures. RESULT(S): We identified 2,250 differentially expressed probe sets. One hundred twenty probe sets showed >2-fold change, of which 77 (64.2%) were up-regulated and 43 (35.8%) down-regulated. Genes involved in transcription were most overrepresented, with 43 out of 97 (44.3%) annotated probes, e.g., the transcription factor complex activator protein 1, including all three Jun genes (c-Jun, JunB, and JunD), two Fos genes (c-Fos and FosB), and activating transcription factor 3. In a Database for Annotation, Visualization, and Integrated Discovery analysis of the 2,007 down-regulated probe sets, proteins of the ribosome pathway and of two pathways involved in protein degradation, i.e., proteasome- and ubiquitin-mediated proteolysis, were significantly down-regulated. We identified eight breast cancer-associated gene expression signatures significantly overlapping with differentially regulated probe sets after cross-sex HT. CONCLUSION(S): Cross-sex HT in FtM transsexuals leads to the up-regulation and down-regulation of 243 and 2,007 distinct genes, respectively, and is associated with breast cancer-related gene expression signatures.

[State of the hypothalamo-hypophyseal-ovarian system in young nullipara women with ectopia of the cervix of uterus during taking the hormonal contraceptives].

Background diseases of the cervix of the uterus play one of the leading roles in the structure of gynecological pathology and present the risk of the development precancerous changes. Ectopia is observed in the structure of precancerous processes of the cervix of the uterus in 38, 8% of women and in 42, 2% cases of gynecological diseases. Our aim is to investigate the content of gonadotropic and steroid hormones in the blood plasma of young nullipara women with different types of ectopia during taking hormonal contraceptives. Cohort study has been carried out by using simple blind method. The quantitative data analyses were performed using the Statistical Package for the Social Sciences (SPSS) in order to reveal the correlation between taking of oral hormonal contraceptives and the hormone content in the blood plasma among young nullipara women with different types of ectopia. Descriptive statistics were calculated for all the study variables. The results displayed correlation between taking the oral hormonal contraceptives and changes of hormonal background in young women with ectopia of the cervix of the uterus during taking hormonal contraceptives. The study show that the secretions of gonadotropic hormone and ovary hormone peculiarities depend on the type of ectopia of the cervix of the uterus. The effect of hormonal contraception on cervix of the uterus of young nullipara women with ectopia was investigated. The oral contraceptive, Exluton is recommended in young nullipara women with ectopia.

Birth control pills and nonprofessional voice: acoustic analyses.

PURPOSE: Two studies are presented here. Study 1 was aimed at evaluating whether the voice characteristics of women who use birth control pills that contain different progestins differ from the voice characteristics of a control group. Study 2 presents a meta-analysis that combined the results of Study 1 with those from 3 recent studies that compared voices of women who use and do not use birth control pills. METHOD: In Study 1, voice samples from 30 women with no history of voice training, who use pills with different progestins (drospirenone, desogestrel, gestodene), and 10 women who do not use the pill were recorded at specific time points across the menstrual cycle and were analyzed acoustically. In Study 2, results from Study 1 were analyzed jointly with results from three recent studies, which used similar methodologies. RESULTS: Results of Study 1 did not reveal acoustic differences in sustained phonation of vowels across the pill groups and controls. Results of the meta-analysis performed in Study 2 indicated that pill users exhibited lower jitter and shimmer values on sustained vowels, whereas no difference of fundamental frequency was observed among women who use the pill. CONCLUSIONS: These results support findings from previous studies, which suggested that no adverse effect on voice was detected among nonprofessional speakers who use new-generation monophasic birth control pills, for the measures studied. Furthermore, results of the meta-analysis suggested that some acoustic properties of the voice, which are reflected in perturbation measures in sustained vowels, may be improved among women who use the pill.

Effects of intranasal 17beta-estradiol administration on serum bioactive interleukin-6 and C-reactive protein levels in healthy postmenopausal women.

OBJECTIVE: Oral estrogen increases the levels of C-reactive protein (CRP), which is an independent risk factor for coronary heart disease in healthy individuals. The aim of our study was to investigate the effects of intranasal 17beta-estradiol (E2) on serum CRP and its most potent stimulant, interleukin-6 in healthy postmenopausal women. DESIGN: Thirty-six healthy postmenopausal women (45-54 y) were enrolled. According to their individual preferences, they were assigned to intranasal (n = 10), transdermal (n = 14), or oral (n = 12) continuous E2 treatment with a sequential progestin (10-14 d in a 28-d cycle). Blood samples were drawn at baseline and after 3, 6, and 12 months during the estrogen-only phase to adjust for the progestin effect. RESULTS: In women taking intranasal or transdermal E2, there were no significant changes in median serum CRP levels during the 12-month treatment period. In women taking oral E2 preparations, serum median CRP levels were significantly higher compared to baseline after 6 and 12 months of the therapy (P < 0.05). Conversely, serum median bioactive interleukin-6 levels were significantly lower after 6 and 12 months in women taking E2 intranasally or orally and after 12 months in women taking E2 transdermally (P < 0.05). CONCLUSIONS: The results of our study show that intranasal, similarly to transdermal, E2 administration does not increase serum CRP levels in postmenopausal women. They also support the hypothesis that CRP increase during oral estrogen treatment is not mediated by the enhancement of interleukin-6 production by the immune cells but is rather caused by the hepatic first-pass metabolism effect.

Two routes of hormonal replacement therapy in symptomatic menopausal women after kidney transplantation.

OBJECTIVES: The assessment of efficacy and safety of two regimens of hormonal replacement therapy (HRT) in women after kidney transplantation with climacteric symptoms. MATERIAL AND METHODS: Combined transdermal or transdermal-oral hormonal replacement therapy was administered to 86 kidney-transplanted women, aged 31-52 years, with moderate to severe climacteric symptoms in years 1995-2005. The patients underwent follow-up examinations one, three and six months after onset of the therapy and every four months subsequently. Blood pressure, body weight, sex hormone profile, serum parameters of both kidney and liver function, endometrial image in transvaginal sonography and reduction of climacteric symptoms were assessed. RESULTS: The mean time of the therapy was 5.6 years for transdermal-oral regimen (54 patients) and 4.7 years for transdermal regimen (32 patients). Most patients reported reduction of climacteric symptoms and improved life quality after 6 months of HRT. 28% of women discontinued therapy for medical indications, most often due to significant deterioration of liver function. One case of profound vein thrombosis was noted. 21% of women decided to discontinue therapy after the results of the WHI trial had been published. CONCLUSIONS: Hormonal replacement therapy is effective in climacteric symptoms relief and improvement of life quality in kidney transplanted women. Higher rate of side effects observed in that group of patients contributes to the need for frequent, attentive surveillance. Further studies should be conducted to establish the optimal doses and routes of administration of HRT as well as to assess the range of necessary follow-up examinations.

A 3-year double-blind, randomized, controlled study on the influence of two oral contraceptives containing either 20 microg or 30 microg ethinylestradiol in combination with levonorgestrel on bone mineral density.

In this first prospective, double-blind, randomized, parallel-group study we evaluated the influence of two combined oral contraceptives on bone mineral density (BMD) and metabolic bone parameters. One dose-reduced preparation contained 20 microg ethinylestradiol (EE) in combination with 100 microg levonorgestrel (LNG) (20/100) was compared with the reference preparation which contained 30 microg EE in combination with 150 microg LNG (30/150). Data from 48 volunteers aged 20-35 years were obtained over an observation period of 36 treatment cycles. The direction of the change (increase or decrease) in all investigated bone-related variables was similar in both treatment groups. As compared to baseline, bone mineral density decreased by 0.4% in the 20/100 group and by 0.8% in the 30/150 group after 36 treatment cycles. These changes were not significantly different between the two treatment groups (p = 0.902). For bone-specific alkaline phosphatase, we measured a mean increase of 55.4% (20/100 group) and of 113.2% (30/150 group) after 36 treatment cycles. The two treatments did not differ statistically significantly (p = 0.522). With respect to cross-linked N-telopeptides (NTx), we detected a decrease of the mean NTx urine concentrations of 21.1% (20/100) and of 13.4% (30/150). These changes also did not significantly differ between the two treatments (p = 0.613). Both study treatments were safe and well-tolerated by all volunteers participating in the study. In conclusion, BMD did not change during the 3-year observation period. Thus, both trial preparations containing either 20 or 30 microg EE in combination with LNG were capable of maintaining BMD in young fertile women. There is no reason to assume that the EE dose reduction had any negative impact on BMD. Because there were no differences in BMD between the treatment groups, it can be assumed that even lower dosages than 20 microg EE might be sufficient for bone protection. Biochemical markers provided evidence for a reduced bone resorption.

Use of progestogen-only contraceptives/medications and lipid parameters in women age 40 to 42 years: results of a population-based cross-sectional Norwegian Survey.

This population-based cross-sectional study assessed lipid and lipoprotein parameters in women using progestogen-only contraceptives or medications and in those using no hormones. Unselected women about age 40 to 42 years were invited, and the participation rate was 65.6%. A total of 30,636 women were premenopausal, not pregnant, and used either a progestogen [n = 3000, including 2463 users of a intrauterine device (IUD) with levonorgestrel 20 microg/24 h] or no sex hormones. Those using the hormone-releasing IUD reported better health and a healthier lifestyle than nonusers of hormones, while women using depot medroxyprogesterone acetate had a less healthy lifestyle. Compared with nonusers of hormones, users of a levonorgestrel IUD were more likely to have high density lipoprotein (HDL)-cholesterol concentrations < or =1.1 mmol/L (odds ratio 1.4; 95% CI 1.2-1.5), while users of oral norethisterone or lynestrenol, or depot medroxyprogesterone acetate had a doubled to tripled risk of low HDL-cholesterol concentrations. Use of the IUD with levonorgestrel was also linked with a decreased risk of high serum triglycerides and of high non-HDL-cholesterol concentrations and a total/HDL-cholesterol ratio similar to that of nonusers of hormones.

Prospective randomized study comparing the GnRH-agonist leuprorelin acetate and the gestagen lynestrenol in the treatment of severe endometriosis.

Endometriosis is thought to be an ovarian-dependent benign disease that affects up to 12% of women during their reproductive life. For the past ten years the gonadotropin-releasing hormone (GnRH)-agonists have been proved effective and safe drugs in the treatment of endometriosis. Nevertheless, gestagens such as lynestrenol still remain the most often used hormonal drugs for the treatment of this disease. The primary objective of this study was to compare the efficacy of the GnRH-agonist leuprorelin acetate depot (LAD) (Enantone-Gyn) 3.75 mg subcutaneously per month with that of the gestagen lynestrenol (LYN) (Orgametril) 5 mg orally twice per day in women with severe endometriosis, in terms of postoperative revised American Fertility Society (r-AFS) scores I-IV at first-look laparoscopy (score after removal of endometriotic lesions or adhesions) to the r-AFS score after six months' treatment. Secondary objectives were the improvement of clinical symptoms and the side-effect profile. Forty-eight women with postoperative r-AFS scores I-IV were evaluated in an open prospective randomized study between 1996 and 1998. All the participants underwent a first-look laparoscopy with resection of endometriotic lesions and six months' therapy with one of the above mentioned drugs, and a further second-look laparoscopy. The six months' treatment with LAD or LYN led to a significant reduction of the r-AFS score points in both groups. The mean r-AFS score in points for the LAD group after the first-look laparoscopy was 21.8 and was 27.2 for the LYN group. After the medical treatment a mean value of 11.5 points was observed in the LAD group compared with a mean value of 25.5 in the LYN group. This difference was statistically significant (p = 0.000014, Wilcoxon test). The improvement in the symptoms of dysmenorrhea, chronic pelvic pain and dyspareunia was also more pronounced in the LAD-treated group. LAD was more effective than LYN in the suppression of circulating serum 17 beta-estradiol levels after 6 months of treatment (mean 27.7 +/- 9.3 pg/ml versus 42.6 +/- 59.3 pg/ml). All the observed side-effects were deemed tolerable by the women who participated in this study. As the reduction of the r-AFS score in points was much more pronounced in the LAD group than in the LYN group, GnRH-agonists should therefore be used as first-choice drugs in the treatment of endometriosis. Due to the limited treatment of 6 months' duration of GnRH-agonists, gestagens might be used as second-line drugs for long-term and continuous treatment in the management of endometriosis to maintain the primary beneficial effect of GnRH-agonist treatment in patients who have completed their families.

Leuprorelin depot 3.75 mg versus lynestrenol in the preoperative treatment of symptomatic uterine myomas: a multicentre randomised trial.

OBJECTIVES: To compare the effect of the gonadotrophin-releasing hormone agonist leuprorelin and progestin lynestrenol, given prior to surgical treatment of symptomatic uterine myomas, on the pre-operative symptoms, tolerance, and operative blood loss. STUDY DESIGN: Fifty-six women were randomly selected to receive, during 16 weeks, either monthly subcutaneous injections of leuprorelin 3.75 mg sustained release (n=33) or lynestrenol 5 mg two tabs per day (5th to the 25th menstrual cycle) (n=23). RESULTS: Intent-to-treat analysis of the main efficacy criterion, namely ultrasonographic reduction of myoma(s) diameter, showed a significant difference in favour of leuprorelin (P=0.02) with a mean decrease of 26.5+/-4.5% (n=29) as opposed to 7.3+/-5% in the lynestrenol group (n=17). Clinical improvement was satisfactory in both groups. Hematocrit decrease between the preoperative value and the value measured 48 h postoperatively was significantly lower in the leuprorelin group than in the lynestrenol one (P=0.02) (for hemoglobin: P=0.07). CONCLUSION: Leuprorelin was more effective than lynestrenol because of its more intense antigonadotropic activity. The tolerance was good, reflecting each drug mechanism of action.

Fertility regulation in nursing women. IX. Contraceptive performance, duration of lactation, infant growth, and bleeding patterns during use of progesterone vaginal rings, progestin-only pills, Norplant implants, and Copper T 380-A intrauterine devices.

This study evaluated the performance of progesterone vaginal rings (n = 187), progestin-only pills (n = 117), Norplant implants (n = 120), and Copper T 380-A intrauterine devices (n = 122) in lactating women. Contraceptive efficacy, bleeding pattern, and influence of the method upon breastfeeding duration and infant growth were compared with those of untreated women (n = 236) who relied on lactational infertility. Participants were healthy, 18 to 38 years, had had a normal delivery, and were intending to breastfeed for as long as possible. Contraceptives were initiated at day 57 +/- 3 postpartum. Results are reported for the first year of use. All methods were highly effective, with pregnancy rates below 1%. None affected breastfeeding performance or the rate of infant growth. Users of the progestin-only methods experienced a period of lactational amenorrhea 4 to 5 months longer than did users of Copper T or untreated women. More than half of the women in each contraceptive group reported a bleeding in the first month after treatment initiation, which was not considered in the calculation of the duration of amenorrhea. Prolonged or frequent bleedings were infrequent. The proportion of bleedings lasting more than 10 days ranged from 0 in the progestin-only pills group to 7% in the Norplant implants group. The four methods, initiated around the eighth postpartum week, provided effective contraception with no negative effects upon lactation or infant growth and without the bleeding problems associated with their use in nonlactating women.

Hormonal inhibition of endometrium for transcervical endometrial ablation--a prospective study with a 2-year follow-up.

OBJECTIVE: To determine the best pretreatment of the endometrium prior to roller ball endometrial ablation. STUDY DESIGN: Forty patients with recurrent hypermenorrhea underwent diagnostic hysteroscopy and dilation and curettage. They were then assigned to receive either no pretreatment or pretreatment with danazol, a GnRH-analogue, or a gestagen prior to roller ball endometrial ablation. Endometrial suppression was estimated by the surgeon at the time of the procedure, and endometrial biopsies were obtained. Patients were followed for 24 months. RESULTS: The subjective estimation of the surgeon showed a sufficient pretreatment after danazol or a GnRH-analogue in 90% of the cases. Histological findings correlated with these findings. The highest level of amenorrhoea at 2 years of follow-up was also reached after danazol or GnRH-analogue pretreatment. CONCLUSIONS: Danazol- or GnRH-analogue should be used for pretreatment prior to endometrial ablation using the roller ball technique.
