RESUMEN
OBJECTIVES: To characterise contemporary trends in the hormonal management of endometriosis in adolescent and young adult patients with biopsy-proven endometriosis. METHODS: Retrospective chart review of women aged 14-25 years who underwent laparoscopy for pelvic pain with biopsy-proven endometriosis between January 2011 and September 2020 at an academic tertiary hospital system. The final sample included 91 patients with biopsy-confirmed endometriosis. RESULTS: Combined oral contraceptives (COCs) were the most common initial treatment (64% of patients). Progestin-only formulations (low- and high-dose norethindrone acetate) were offered to younger patients (age 15.9 ± 2.7 years) than those offered COCs (19.9 ± 3.3 years) and levonorgestrel intrauterine devices (LNG-IUDs) (21.9 ± 1.7 years). Current treatments varied widely and included COCs (32%), LNG-IUDs (18%), oral progestins (low- and high-dose norethindrone, medroxyprogesterone) (14%), elagolix (9%), and leuprolide (8%). Oral adjuncts to LNG-IUD were common: usually low- or high-dose norethindrone (37% of patients with an LNG-IUD), but also included progesterone, COCs, and elagolix. CONCLUSIONS: Oral progestins, LNG-IUDs, and COCs were the mainstay of initial treatment. Subsequent treatments varied widely and included COCs, LNG-IUDs, oral progestins, elagolix, leuprolide, and combinations of these agents. We observed that most young women switched between therapies, suggesting that a personalised approach is often used to determine treatment plans among the wide range of options currently available. This study helps define the spectrum of treatment regimens for endometriosis in adolescent females.

STUDY QUESTION: Does linzagolix administered orally once daily for up to 3 months at a dose of 75 mg alone or 200 mg in combination with add-back therapy (ABT) (1.0 mg estradiol; 0.5 mg norethindrone acetate, also known as norethisterone acetate [NETA]) demonstrate better efficacy than placebo in the management of endometriosis-related dysmenorrhea and non-menstrual pelvic pain? SUMMARY ANSWER: Combining 200 mg linzagolix with ABT was found to significantly reduce dysmenorrhea and non-menstrual pelvic pain at 3 months of therapy, while a daily dose of 75 mg linzagolix yielded a significant decrease only in dysmenorrhea at 3 months. WHAT IS KNOWN ALREADY?: A previously published Phase 2, dose-finding study reported that at a dose of 200 mg daily, linzagolix promotes full suppression of estradiol secretion to serum levels below 20 pg/ml and noted that the addition of ABT may be needed to manage hypoestrogenic side effects. At lower doses (75 mg and 100 mg/day), linzagolix maintains estradiol values within the target range of 20-60 pg/ml, which could be ideal to alleviate symptoms linked to endometriosis. STUDY DESIGN, SIZE, DURATION: EDELWEISS 3 was a multicenter, prospective, randomized, placebo-controlled, double-blind, double-dummy Phase 3 study to evaluate the safety and efficacy of linzagolix for the treatment of moderate-to-severe endometriosis-associated pain. Treatment was administered orally once daily for up to 6 months. PARTICIPANTS/MATERIALS, SETTING, METHODS: In the EDELWEISS 3 trial, 486 subjects with moderate-to-severe endometriosis-associated pain were randomized at a 1:1:1 ratio to one of the three study groups: placebo, 75 mg linzagolix alone or 200 mg linzagolix in association with ABT. Pain was measured daily on a verbal rating scale and recorded in an electronic diary. MAIN RESULTS AND THE ROLE OF CHANCE: At 3 months, the daily 200 mg linzagolix dose with ABT met the primary efficacy objective, showing clinically meaningful and statistically significant reductions in dysmenorrhea and non-menstrual pelvic pain, with stable or decreased use of analgesics. The proportion of responders for dysmenorrhea in the 200 mg linzagolix with ABT group was 72.9% compared with 23.5% in the placebo group (P < 0.001), while the rates of responders for non-menstrual pelvic pain were 47.3% and 30.9% (P = 0.007), respectively. The 75 mg linzagolix daily dose demonstrated a clinically meaningful and statistically significant reduction in dysmenorrhea versus placebo at 3 months. The proportion of responders for dysmenorrhea in the 75 mg linzagolix group was 44.0% compared with 23.5% in the placebo group (P < 0.001). Although the 75 mg dose showed a trend toward reduction in non-menstrual pelvic pain at 3 months relative to the placebo, it was not statistically significant (P = 0.279). Significant improvements in dyschezia and overall pelvic pain were observed in both linzagolix groups when compared to placebo. Small improvements in dyspareunia scores were observed in both linzagolix groups but they were not significant. In both groups, hypoestrogenic effects were mild, with low rates of hot flushes and bone density loss of <1%. A daily dose of 200 mg linzagolix with ABT or 75 mg linzagolix alone was found to significantly reduce dysmenorrhea and non-menstrual pelvic pain also at 6 months of therapy. LIMITATIONS, REASONS FOR CAUTION: Efficacy was compared between linzagolix groups and placebo; however, it would be useful to have results from comparative studies with estro-progestogens or progestogens. It will be important to ascertain whether gonadotropin-releasing hormone antagonists have significant benefits over traditional first-line medications. WIDER IMPLICATIONS OF THE FINDINGS: Linzagolix administered orally once daily at a dose of 200 mg in combination with add-back therapy (ABT) demonstrated better efficacy and safety than placebo in the management of moderate-to-severe endometriosis-associated pain. The quality of life was improved and the risks of bone loss and vasomotor symptoms were minimized due to the ABT. The 75 mg dose alone could be suitable for chronic treatment of endometriosis-associated pain without the need for concomitant hormonal ABT, but further research is needed to confirm this. If confirmed, it would offer a viable option for women who do not want to wish to have ABT or for whom it is contraindicated.

An oral fixed-dose combination of relugolix/estradiol/norethisterone (also known as norethindrone) acetate [Myfembree® (USA); Ryeqo® (EU)] (hereafter referred to as relugolix combination therapy) has been approved in the USA for the management of moderate to severe pain associated with endometriosis in premenopausal women and in the EU for the symptomatic treatment of endometriosis in adult women of reproductive age with a history of previous medical or surgical treatment for their endometriosis. The gonadotropin-releasing hormone (GnRH) receptor antagonist relugolix decreases estradiol and progesterone levels, while the addition of estradiol/norethisterone acetate mitigates hypoestrogenic effects including bone mineral density (BMD) loss and vasomotor symptoms. In two pivotal phase III trials, relugolix combination therapy significantly improved dysmenorrhoea and non-menstrual pelvic pain in premenopausal women with moderate to severe endometriosis. The combination also reduced overall pelvic pain and dyspareunia, reduced analgesic and opioid use, and improved health-related quality of life. The efficacy of relugolix combination therapy was sustained over the longer term (up to 2 years). Relugolix combination therapy was generally well tolerated and BMD loss over time was minimal. With the convenience of a once daily oral dosing regimen, relugolix combination therapy is a valuable addition to the options currently available for the management of endometriosis-associated pain.
Endometriosis is a disease where tissue similar to the lining of the uterus grows outside the uterus and may reach other organs. This causes chronic pain as a result of increased inflammation and scar tissue. Women with endometriosis may experience painful menstrual periods, pelvic pain between periods, pain during sex, painful bowel movements and painful urination. Recently, a fixed-dose tablet comprising relugolix, estradiol and norethisterone (also known as norethindrone) acetate [Myfembree® (USA); Ryeqo® (EU)] (hereafter referred to as relugolix combination therapy) has been approved to treat endometriosis-associated pain. The treatment works by decreasing levels of ovarian hormones (estrogen and progesterone). In clinical trials, relugolix combination therapy improved period pain and pain between periods in women with moderate to severe pain associated with endometriosis. The treatment also improved other symptoms (overall pelvic pain and pain during sex), reduced the need for pain medications and improved health-related quality of life. Relugolix combination therapy was generally well tolerated and caused minimal bone loss, which is known to occur with some hormone therapies. With the convenience of a once daily oral pill, relugolix combination therapy is a valuable addition to the options currently available for women with endometriosis-associated pain.

OBJECTIVES: To compare the effectiveness of dienogest (DIE) and norethisterone acetate (NETA) regimens in the treatment of endometrial hyperplasia (EH) without atypia. METHODS: Participants were premenopausal women with irregular uterine bleeding, and endometrial hyperplasia without atypia on endometrial biopsy. Enrolled patients were randomly allocated into two groups: group I got DIE 2 mg/day (orally Visanne) for 14 days (10th to the 25th day of cycle) while group II received between the 16th and 25th day of the cycle, norethisterone acetate (NETA) 15 mg/d (orally Primolut Nor) was administered for 10 days. Both groups continued the therapy for six months. RESULTS: The DIE group showed a higher resolution (32.7%) and regression (57.7%) than NETA group (31% & 37.9%, respectively) with significant regression (p = 0.039). No progression in DIE group while four (6.9%) women in NETA group were recorded a progression to complex type without a significance. Also, NETA group showed a significant persistence rate (22.5%) than DIE group (3.8%) (p = 0.005). Also number in NETA group managed by hysterectomy with significant difference (p = 0.042). CONCLUSION: If used as first-line treatment, Dienogest produces a better rate of regression and a lower incidence of hysterectomy than Norethisterone Acetate does when used in EH without atypia.

OBJECTIVES: Fostemsavir, a prodrug of temsavir, is indicated for heavily treatment-experienced adults with multidrug-resistant HIV-1 infection, antiretroviral (ARV) intolerance, or safety considerations. Understanding drug-drug interactions (DDIs) is important in individuals taking fostemsavir with hormonal contraceptives or menopausal or gender-affirming hormonal therapies. METHODS: Effect of temsavir (active moiety) on the pharmacokinetics of ethinyl estradiol (EE) and norethindrone (NET) was evaluated in an open-label, single-sequence, four-cycle, four-treatment study in 26 healthy female participants (study 206279, NCT02480881). Relevant ARV-contraceptive interaction studies and guideline recommendations were reviewed; that information was then applied to other contraceptive methods and hormone-based therapies to predict the impact of fostemsavir co-administration. RESULTS: Temsavir increased EE concentrations by 40% and had no effect on NET concentrations. Fostemsavir co-administration with hormone therapy is not expected to impact hormone treatment efficacy. Fostemsavir did not impact progestin; therefore, progestin-only and non-hormonal contraceptives will not be impacted by fostemsavir. Recommendations for co-administration of fostemsavir and hormonal contraceptives or menopausal or gender-affirming hormone therapies are based upon known and predicted DDIs, ensuring adequate hormonal concentrations to maintain the target effect. CONCLUSIONS: Applying the results of Study 206279 and other relevant ARV-contraceptive studies, we recommend that when co-administering fostemsavir with combined oral contraceptives (COCs) and other oestrogen-based therapies, EE dose should not exceed 30 µg or equivalent, and caution is advised in the case of individuals with risk factors for thromboembolic events. Other oestrogen-based therapies may be co-administered with fostemsavir, with monitoring of oestrogen concentrations and appropriate dose adjustments. No impact of fostemsavir on COC efficacy is expected.

INTRODUCTION: Although several studies suggest beneficial effects of low-dose estrogen-progestins (LEPs) and progestins on dysmenorrhea in Japanese women, the difference in efficacy between drugs remains unknown. METHODS: We identified studies by searching the MEDLINE, Cochrane Library, and ICHUSHI databases and included randomized controlled trials (RCTs) that used total dysmenorrhea score and visual analogue scale (VAS) as outcome measures to evaluate LEPs and progestins for primary and secondary dysmenorrhea. We analyzed results by meta-analysis and network meta-analysis (NMA). RESULTS: We identified 10 articles on eight RCTs and included seven drugs (six LEPs and one progestin, i.e., dienogest) and placebo in the analysis. Meta-analysis showed improvements in total dysmenorrhea score and VAS for almost all drugs compared with placebo. In NMA, VAS in secondary dysmenorrhea improved more with dienogest than with norethisterone/ethinylestradiol (mean difference - 25.84 [95% CrI - 44.46 to - 7.15]). In the comparison of administration regimens, VAS improved more with progestin-continuous than LEP-cyclic and the surface under the cumulative ranking (SUCRA) of LEP-extended and progestin-continuous appeared to be higher than that of LEP-cyclic. CONCLUSIONS: We confirmed that LEPs and dienogest are effective for primary and secondary dysmenorrhea and suggest that continuous regimens may be more effective than cyclic regimens in improving outcomes.

BACKGROUND: Heavy menstrual bleeding (HMB) impacts the quality of life of otherwise healthy women. The perception of HMB is subjective and management depends upon, among other factors, the severity of the symptoms, a woman's age, her wish to get pregnant, and the presence of other pathologies. Heavy menstrual bleeding was classically defined as greater than or equal to 80 mL of blood loss per menstrual cycle. Currently the definition is based on the woman's perception of excessive bleeding which is affecting her quality of life. The intrauterine device was originally developed as a contraceptive but the addition of progestogens to these devices resulted in a large reduction in menstrual blood loss: users of the levonorgestrel-releasing intrauterine system (LNG-IUS) reported reductions of up to 90%. Insertion may, however, be regarded as invasive by some women, which affects its acceptability. OBJECTIVES: To determine the effectiveness, acceptability and safety of progestogen-releasing intrauterine devices in reducing heavy menstrual bleeding. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL (from inception to June 2019); and we searched grey literature and for unpublished trials in trial registers. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in women of reproductive age treated with LNG-IUS devices versus no treatment, placebo, or other medical or surgical therapy for heavy menstrual bleeding. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data, assessed risk of bias and conducted GRADE assessments of the certainty of evidence. MAIN RESULTS: We included 25 RCTs (2511 women). Limitations in the evidence included risk of attrition bias and low numbers of participants. The studies compared the following interventions. LNG-IUS versus other medical therapy The other medical therapies were norethisterone acetate, medroxyprogesterone acetate, oral contraceptive pill, mefenamic acid, tranexamic acid or usual medical treatment (where participants could choose the oral treatment that was most suitable). The LNG-IUS may improve HMB, lowering menstrual blood loss according to the alkaline haematin method (mean difference (MD) 66.91 mL, 95% confidence interval (CI) 42.61 to 91.20; 2 studies, 170 women; low-certainty evidence); and the Pictorial Bleeding Assessment Chart (MD 55.05, 95% CI 27.83 to 82.28; 3 studies, 335 women; low-certainty evidence). We are uncertain whether the LNG-IUS may have any effect on women's satisfaction up to one year (RR 1.28, 95% CI 1.01 to 1.63; 3 studies, 141 women; I² = 0%, very low-certainty evidence). The LNG-IUS probably leads to slightly higher quality of life measured with the SF-36 compared with other medical therapy if (MD 2.90, 95% CI 0.06 to 5.74; 1 study: 571 women; moderate-certainty evidence) or with the Menorrhagia Multi-Attribute Scale (MD 13.40, 95% CI 9.89 to 16.91; 1 trial, 571 women; moderate-certainty evidence). The LNG-IUS and other medical therapies probably give rise to similar numbers of women with serious adverse events (RR 0.91, 95% CI 0.63 to 1.30; 1 study, 571 women; moderate-certainty evidence). Women using other medical therapy are probably more likely to withdraw from treatment for any reason (RR 0.49, 95% CI 0.39 to 0.60; 1 study, 571 women, moderate-certainty evidence) and to experience treatment failure than women with LNG-IUS (RR 0.34, 95% CI 0.26 to 0.44; 6 studies, 535 women; moderate-certainty evidence). LNG-IUS versus endometrial resection or ablation (EA) Bleeding outcome results are inconsistent. We are uncertain of the effect of the LNG-IUS compared to EA on rates of amenorrhoea (RR 1.21, 95% CI 0.85 to 1.72; 8 studies, 431 women; I² = 21%; low-certainty evidence) and hypomenorrhoea (RR 0.98, 95% CI 0.73 to 1.33; 4 studies, 200 women; low-certainty evidence) and eumenorrhoea (RR 0.55, 95% CI 0.30 to 1.00; 3 studies, 160 women; very low-certainty evidence). We are uncertain whether both treatments may have similar rates of satisfaction with treatment at 12 months (RR 0.95, 95% CI 0.85 to 1.07; 5 studies, 317 women; low-certainty evidence). We are uncertain if the LNG-IUS compared to EA has any effect on quality of life, measured with SF-36 (MD -14.40, 95% CI -22.63 to -6.17; 1 study, 33 women; very low-certainty evidence). Women with the LNG-IUS compared with EA are probably more likely to have any adverse event (RR 2.06, 95% CI 1.44 to 2.94; 3 studies, 201 women; moderate-certainty evidence). Women with the LNG-IUS may experience more treatment failure compared to EA at one year follow up (persistent HMB or requirement of additional treatment) (RR 1.78, 95% CI 1.09 to 2.90; 5 studies, 320 women; low-certainty evidence); or requirement of hysterectomy may be higher at one year follow up (RR 2.56, 95% CI 1.48 to 4.42; 3 studies, 400 women; low-certainty evidence). LNG-IUS versus hysterectomy We are uncertain whether the LNG-IUS has any effect on HMB compared with hysterectomy (RR for amenorrhoea 0.52, 95% CI 0.39 to 0.70; 1 study, 75 women; very low-certainty evidence). We are uncertain whether there is difference between LNG-IUS and hysterectomy in satisfaction at five years (RR 1.01, 95% CI 0.94 to 1.08; 1 study, 232 women; low-certainty evidence) and quality of life (SF-36 MD 2.20, 95% CI -2.93 to 7.33; 1 study, 221 women; low-certainty evidence). Women in the LNG-IUS group may be more likely to have treatment failure requiring hysterectomy for HMB at 1-year follow-up compared to the hysterectomy group (RR 48.18, 95% CI 2.96 to 783.22; 1 study, 236 women; low-certainty evidence). None of the studies reported cost data suitable for meta-analysis. AUTHORS' CONCLUSIONS: The LNG-IUS may improve HMB and quality of life compared to other medical therapy; the LNG-IUS is probably similar for HMB compared to endometrial destruction techniques; and we are uncertain if it is better or worse than hysterectomy. The LNG-IUS probably has similar serious adverse events to other medical therapy and it is more likely to have any adverse events than EA.

OBJECTIVE: To compare the effects of Dienogest (D) and Norethindrone acetate (N) in symptomatic women with ovarian endometriomas, analyzing the efficacy in reducing endometrioma size and symptom relief and drug tolerability. STUDY DESIGN: Retrospective study including 135 symptomatic women with ultrasonographic diagnosis of ovarian endometrioma. Women were divided into two groups: 1) women who received D 2 mg/day (group D); 2) women who received N 2.5 mg/day (group N). Women were evaluated at therapy prescription and after 6 and 12 months of treatment: transvaginal ultrasound was performed to assess the mean diameter of endometriomas, a Visual Analogue Scale was used to rank endometriosis related symptoms (dysmenorrhea, dyspareunia, chronic pelvic pain). The main outcome measure was the comparison between the 2 groups in terms of variations in endometrioma size and endometriosis related symptoms during the follow-up. Drug tolerability was also analyzed in terms of side effects. RESULTS: A reduction in ovarian endometrioma size was observed during treatment in both groups, with no significant differences between groups D and N. Endometriosis related symptoms decreased in both groups, but the decrease was significantly higher in group D than in group N for all symptoms, both at 6 and 12 months of treatment. Regarding drug tolerability, uterine bleeding/spotting and weight gain were reported more frequently by women in the group N than women in the group D, both at 6 and 12 months of treatment. CONCLUSION: Progestin therapy with D or N appears to be effective in reducing the size of endometriomas and related symptoms, with a greater effect on symptoms relief and higher tolerability in women treated with D.

OBJECTIVE: A systematic review was carried out of studies of women with endometriosis, to examine the evidence for efficacy of the use of hormonal contraception to improve disease-related pain and decrease postoperative risk of disease recurrence. METHODS: A search of the Medline/PubMed and Embase databases was performed to identify all published English language studies on hormonal contraceptive therapies (combined hormonal contraceptives [CHCs], combined oral contraceptives [COCs], progestin-only pills [POPs] and progestin-only contraceptives [POCs]) in women with a validated endometriosis diagnosis, in comparison with placebo, comparator therapies or other hormonal therapies. Main outcome measures were endometriosis-related pain (dysmenorrhoea, pelvic pain and dyspareunia), quality of life (QoL) and postoperative rate of disease recurrence during treatment. RESULTS: CHC and POC treatments were associated with clinically significant reductions in dysmenorrhoea, often accompanied by reductions in non-cyclical pelvic pain and dyspareunia and an improvement in QoL. Only two COC preparations (ethinylestradiol [EE]/norethisterone acetate [NETA] and a flexible EE/drospirenone regimen) demonstrated significantly increased efficacy compared with placebo. Only three studies found that the postoperative use of COCs (EE/NETA, EE/desogestrel and EE/gestodene) reduced the risk of disease recurrence. There was no evidence that POCs reduced the risk of disease recurrence. CONCLUSIONS: CHCs and POCs are effective for the relief of endometriosis-related dysmenorrhoea, pelvic pain and dyspareunia, and improve QoL. Some COCs decreased the risk of disease recurrence after conservative surgery, but POCs did not. There is insufficient evidence, however, to reach definitive conclusions about the overall superiority of any particular hormonal contraceptive.

INTRODUCTION: Hormone therapy is widely used in the treatment of patients with ovarian endometriosis after surgery, and progestin and gonadotropin-releasing hormone (GnRH) are two of the most widely used hormones. This study aimed to compare the outcomes of progestin and GnRH in the treatment of ovarian endometriosis after surgery. METHODS: A total of 399 patients with ovarian endometriosis were included and divided into four groups to receive different treatments. Group A received no postoperative hormone therapy; patients in group B1 and B2 were treated with different doses of norethindrone (progestin, 1.2 and 5 mg/day, respectively); patients in group C were treated with GnRH (2.0 mg every 2 weeks). Treatment outcomes including menstrual bleeding profiles, cumulative recurrence rate, incidence of complications, and endometrioma diameter in the case of recurrence were recorded and compared between groups. RESULTS: Compared with group A, group B1, B2 and C showed significantly improved menstrual bleeding profiles and reduced cumulative recurrence rate and endometrioma diameter after recurrence. In addition, compared with group C, menstrual bleeding profiles were significantly improved and cumulative recurrence rate and endometrioma diameter were significantly reduced in group B1 and B2. No significant differences in incidence of complications during treatment were found among groups. After treatment, recurrence rate and endometrioma diameter were significantly increased in group B1, B2, and C. CONCLUSION: Both progestin and GnRH can significantly improve the conditions of patients with ovarian endometriosis after surgery, but progestin may be a better choice. Both therapies are challenged by the increased recurrence rate and endometrioma diameter after treatment.

BACKGROUND: Heavy menstrual bleeding (HMB) is an important physical and social problem for women. Oral treatment for HMB includes antifibrinolytic drugs, which are designed to reduce bleeding by inhibiting clot-dissolving enzymes in the endometrium.Historically, there has been some concern that using the antifibrinolytic tranexamic acid (TXA) for HMB may increase the risk of venous thromboembolic disease. This is an umbrella term for deep venous thrombosis (blood clots in the blood vessels in the legs) and pulmonary emboli (blood clots in the blood vessels in the lungs). OBJECTIVES: To determine the effectiveness and safety of antifibrinolytic medications as a treatment for heavy menstrual bleeding. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO and two trials registers in November 2017, together with reference checking and contact with study authors and experts in the field. SELECTION CRITERIA: We included randomized controlled trials (RCTs) comparing antifibrinolytic agents versus placebo, no treatment or other medical treatment in women of reproductive age with HMB. Twelve studies utilised TXA and one utilised a prodrug of TXA (Kabi). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. The primary review outcomes were menstrual blood loss (MBL), improvement in HMB, and thromboembolic events. MAIN RESULTS: We included 13 RCTs (1312 participants analysed). The evidence was very low to moderate quality: the main limitations were risk of bias (associated with lack of blinding, and poor reporting of study methods), imprecision and inconsistency.Antifibrinolytics (TXA or Kabi) versus no treatment or placeboWhen compared with a placebo, antifibrinolytics were associated with reduced mean blood loss (MD -53.20 mL per cycle, 95% CI -62.70 to -43.70; I² = 8%; 4 RCTs, participants = 565; moderate-quality evidence) and higher rates of improvement (RR 3.34, 95% CI 1.84 to 6.09; 3 RCTS, participants = 271; moderate-quality evidence). This suggests that if 11% of women improve without treatment, 43% to 63% of women taking antifibrinolytics will do so. There was no clear evidence of a difference between the groups in adverse events (RR 1.05, 95% CI 0.93 to 1.18; 1 RCT, participants = 297; low-quality evidence). Only one thromboembolic event occurred in the two studies that reported this outcome.TXA versus progestogensThere was no clear evidence of a difference between the groups in mean blood loss measured using the Pictorial Blood Assessment Chart (PBAC) (MD -12.22 points per cycle, 95% CI -30.8 to 6.36; I² = 0%; 3 RCTs, participants = 312; very low quality evidence), but TXA was associated with a higher likelihood of improvement (RR 1.54, 95% CI 1.31 to 1.80; I² = 32%; 5 RCTs, participants = 422; low-quality evidence). This suggests that if 46% of women improve with progestogens, 61% to 83% of women will do so with TXA.Adverse events were less common in the TXA group (RR 0.66, 95% CI 0.46 to 0.94; I² = 28%; 4 RCTs, participants = 349; low-quality evidence). No thromboembolic events were reported in any group.TXA versus non-steroidal anti-inflammatory drugs (NSAIDs)TXA was associated with reduced mean blood loss (MD -73.00 mL per cycle, 95% CI -123.35 to -22.65; 1 RCT, participants = 49; low-quality evidence) and higher likelihood of improvement (RR 1.43, 95% CI 1.18 to 1.74; 12 = 0%; 2 RCTs, participants = 161; low-quality evidence). This suggests that if 61% of women improve with NSAIDs, 71% to 100% of women will do so with TXA. Adverse events were uncommon and no comparative data were available. No thromboembolic events were reported.TXA versus ethamsylateTXA was associated with reduced mean blood loss (MD 100 mL per cycle, 95% CI -141.82 to -58.18; 1 RCT, participants = 53; low-quality evidence), but there was insufficient evidence to determine whether the groups differed in rates of improvement (RR 1.56, 95% CI 0.95 to 2.55; 1 RCT, participants = 53; very low quality evidence) or withdrawal due to adverse events (RR 0.78, 95% CI 0.19 to 3.15; 1 RCT, participants = 53; very low quality evidence).TXA versus herbal medicines (Safoof Habis and Punica granatum)TXA was associated with a reduced mean PBAC score after three months' treatment (MD -23.90 pts per cycle, 95% CI -31.92 to -15.88; I² = 0%; 2 RCTs, participants = 121; low-quality evidence). No data were available for rates of improvement. TXA was associated with a reduced mean PBAC score three months after the end of the treatment phase (MD -10.40 points per cycle, 95% CI -19.20 to -1.60; I² not applicable; 1 RCT, participants = 84; very low quality evidence). There was insufficient evidence to determine whether the groups differed in rates of adverse events (RR 2.25, 95% CI 0.74 to 6.80; 1 RCT, participants = 94; very low quality evidence). No thromboembolic events were reported.TXA versus levonorgestrel intrauterine system (LIUS)TXA was associated with a higher median PBAC score than TXA (median difference 125.5 points; 1 RCT, participants = 42; very low quality evidence) and a lower likelihood of improvement (RR 0.43, 95% CI 0.24 to 0.77; 1 RCT, participants = 42; very low quality evidence). This suggests that if 85% of women improve with LIUS, 20% to 65% of women will do so with TXA. There was insufficient evidence to determine whether the groups differed in rates of adverse events (RR 0.83, 95% CI 0.25 to 2.80; 1 RCT, participants = 42; very low quality evidence). No thromboembolic events were reported. AUTHORS' CONCLUSIONS: Antifibrinolytic treatment (such as TXA) appears effective for treating HMB compared to placebo, NSAIDs, oral luteal progestogens, ethamsylate, or herbal remedies, but may be less effective than LIUS. There were too few data for most comparisons to determine whether antifibrinolytics were associated with increased risk of adverse events, and most studies did not specifically include thromboembolism as an outcome.

INTRODUCTION: Endometriosis is a chronic estrogen and progestogen responsive inflammatory disease associated with pain symptoms and infertility. The medical therapy of endometriosis aims to induce decidualization within the hormonally dependent ectopic endometrium, and it is often administered to ameliorate women' pain symptoms or to prevent post-surgical disease recurrence. A variety of progestins have been used in monotherapy for the medical management of women with endometriosis. Areas covered: This review aims to offer the reader a complete overview of pharmacokinetic (PK) and clinical efficacy of progestins for the treatment of endometriosis. Expert opinion: Each progestin has a distinct PK parameters and pharmacodynamics affinity not only for progesterone receptor, but also for other steroid receptors, such as estrogen, androgen, and glucocorticoid. Moreover, progestins can also be delivered in different formulations. All these characteristics influence their final biological effect. Randomized, controlled, non-blinded studies support the use of oral progestin-only treatment for pelvic pain associated with endometriosis. Currently, the only two progestins approved by Food and Drug Administration (FDA) for the treatment of endometriosis are norethindrone acetate (NETA) and depot medroxyprogesterone acetate (DMPA).

BACKGROUND: Data evaluating the impact of contraceptives on the vaginal microbiome are limited and inconsistent. OBJECTIVE: We hypothesized that women initiating copper intrauterine device use would have increased bacterial vaginosis and bacterial vaginosis-associated microbes with use compared to women initiating and using hormonal contraceptive methods. STUDY DESIGN: Vaginal swabs (N = 1047 from 266 participants seeking contraception) for Nugent score determination of bacterial vaginosis and quantitative polymerase chain reaction analyses for assessment of specific microbiota were collected from asymptomatic, healthy women aged 18-35 years in Harare, Zimbabwe, who were confirmed to be free of nonstudy hormones by mass spectrometry at each visit. Contraception was initiated with an injectable (depot medroxyprogesterone acetate [n = 41], norethisterone enanthate [n = 44], or medroxyprogesterone acetate and ethinyl estradiol [n = 40]), implant (levonorgestrel [n = 45] or etonogestrel [n = 48]), or copper intrauterine device (n = 48) and repeat vaginal swabs were collected after 30, 90, and 180 days of continuous use. Self-reported condom use was similar across all arms at baseline. Quantitative polymerase chain reaction was used to detect Lactobacillus crispatus, L jensenii, L gasseri/johnsonii group, L vaginalis, L iners, Gardnerella vaginalis, Atopobium vaginae, and Megasphaera-like bacterium phylotype I from swabs. Modified Poisson regression and mixed effects linear models were used to compare marginal prevalence and mean difference in quantity (expressed as gene copies/swab) prior to and during contraceptive use. RESULTS: Bacterial vaginosis prevalence increased in women initiating copper intrauterine devices from 27% at baseline, 35% at 30 days, 40% at 90 days, and 49% at 180 days (P = .005 compared to marginal prevalence at enrollment). Women initiating hormonal methods had no change in bacterial vaginosis prevalence over 180 days. The mean increase in Nugent score was 1.2 (95% confidence interval, 0.5-2.0; P = .001) in women using copper intrauterine devices. Although the frequency and density of beneficial lactobacilli did not change among intrauterine device users over 6 months, there was an increase in the log concentration of G vaginalis (4.7, 5.2, 5.8, 5.9; P = .046) and A vaginae (3.0, 3.8, 4.6, 5.1; P = .002) between baseline and 30, 90, and 180 days after initiation. Among other contraceptive groups, women using depot medroxyprogesterone acetate had decreased L iners (mean decrease log concentration = 0.8; 95% confidence interval, 0.3-1.5; P = .004) and there were no significant changes in beneficial Lactobacillus species over 180 days regardless of contraceptive method used. CONCLUSION: Copper intrauterine device use may increase colonization by bacterial vaginosis-associated microbiota, resulting in increased prevalence of bacterial vaginosis. Use of most hormonal contraception does not alter vaginal microbiota.

STUDY OBJECTIVE: To explore the potential occurrence of long-term side effects and tolerability of gonadotropin-releasing hormone agonist (GnRHa) plus 2 different add-back regimens in adolescent patients with endometriosis. DESIGN: Follow-up questionnaire sent in 2016 to patients who participated in a drug trial between 2008 and 2012. SETTING: Tertiary care center in Boston, Massachusetts. PARTICIPANTS: Female adolescents with surgically confirmed endometriosis (n = 51) who enrolled in a GnRHa plus add-back trial as adolescents. INTERVENTIONS: Leuprolide depot 11.25 mg intramuscular injection every 3 months, plus oral norethindrone acetate 5 mg daily or oral norethindrone acetate 5 mg daily and oral conjugated equine estrogens 0.625 mg daily. MAIN OUTCOME MEASURES: Side effects during and after treatment, irreversible side effects, changes in pain, overall satisfaction. RESULTS: The response rate was 61% (25 of 41; 10 subjects could not be located). Almost all (24 of 25) reported side effects during treatment; 80% (16 of 21) reported side effects lasting longer than 6 months after stopping treatment. Almost half (9 of 20) reported side effects they considered irreversible, including memory loss, insomnia, and hot flashes. Despite side effects, participants rated GnRHa plus add-back as the most effective hormonal medication for treating endometriosis pain; two-thirds (16 of 25) would recommend it to others. More participants who received a modified 2-drug add-back regimen vs standard 1-drug add-back would recommend GnRHa and believed it was the most effective hormonal medication. CONCLUSION: Subjects believed that GnRHa used with add-back was effective and would recommend it to others, despite significant side effects. Those who received 2-drug add-back reported more success than those who received standard add-back. A subset of patients reported side effects they consider to be irreversible.

INTRODUCTION: This patient preference prospective study was designed to compare patients' satisfaction in women with endometriosis treated either by an extended-cycle oral contraception (OC) or by norethindrone acetate (NETA). METHODS: This patient preference prospective study included women of reproductive age with endometriosis. Patients were submitted to one of the following 12 months' treatments: Group A, continuous oral treatment with NETA (2.5â¯mg/day) and Group B, a 91-day extended-cycle OC (LNG/EE 150/30â¯mcg for 84â¯days and EE 10â¯mcg for 7â¯days). Patient satisfaction was the primary endpoint. RESULTS: There was no statistically significant difference in the rate of satisfied patients at 12-month follow up between the two study groups, 82.2% and 68.4% in Group A and Group B respectively (pâ¯=â¯0.143). At 6 and 12-months, there was a significant amelioration in the intensity of all pain in both groups. The median number of days of unscheduled bleeding during the first cycle was significantly higher in Group B compared to Group A. CONCLUSION: Both NETA and extended-cycle OC are effective in treating pain symptoms related to endometriosis. Extended-cycle OC may cause more unscheduled bleeding, but the rate of satisfaction for those who completed the treatment was similar in the two groups.

The purpose of this study was to assess the proportion of patients satisfied with their treatment after a change from a low-dose oral contraceptive (OC) to norethisterone acetate (NETA) because of inefficacy of OC on pain symptoms. To this end, prospective, self-controlled study was conducted on 153 women using OC as a treatment for endometriosis and with persistence of one or more moderate or severe pain symptoms. At baseline and during 12 months after a shift from OC to oral NETA, 2.5 mg/d, pelvic pain was measured by means of a 0- to 10-point numerical rating scale and a multidimensional categorical rating scale. Variations in health-related quality of life, psychological status, and sexual function were also evaluated with validated scales. At the end of the study period, participants indicated the degree of satisfaction with their treatment according to a 5-degree scale from very satisfied to very dissatisfied. A total of 28 women dropped out of the study, the main reason was intolerable side effects (n = 15). At 12-month assessment, 70% of participants were very satisfied or satisfied with NETA treatment (intention-to-treat analysis). Statistically significant improvements were observed in health-related quality of life, psychological status, and sexual function. At per-protocol analysis, almost half of the patients (58/125) reported suboptimal drug tolerability. However, complaints were not severe enough to cause dissatisfaction, drug discontinuation, or request for surgery. These encouraging results could be used to counsel women with symptomatic endometriosis not responding to OC and to inform their decisions on modifications of disease management.
