RESUMEN

Levonorgestrel releasing intrauterine system have excellent contraceptive efficacy with simultaneous lowering of menstruation's blood loss. It could be used for therapy of endometrial hyperplasia in perimenopause. In position of gestagen part of the hormone replacement therapy it has high control of endometrial proliferation. It is conjoined with the zero increasing of risk of thromboembolic disease in combination with transdermal oestrogen's application.

RESUMEN

OBJECTIVES: Given the well-established link between hormonal contraceptives and hypertension risk, and the paucity of research on hormonal contraceptive use dynamics in this particular demographic, we hypothesize that there is a likelihood of low utilization of high-risk hormonal contraceptives among women living with hypertension in SSA. This study investigates the prevalence and factors associated with hormonal contraceptive use among women living with hypertension in the SSA. RESULTS: Only 18.5% of women living with hypertension used hormonal contraceptives. Hormonal contraceptive use was high among women with a higher level of education (aOR = 2.33; 95%CI: 1.73-3.14), those currently working (aOR = 1.38; 95%CI: 1.20-1.59), those who have heard about family planning on the radio (aOR = 1.27, 95%CI: 1.09-1.47), listened to the radio at least once a week (aOR = 1.29, 95%CI: 1.10-1.51), and those residing in rural areas (aOR = 1.32; 95%CI: 1.14-1.54). Conversely, women aged 45-49 exhibited a substantial decrease in the odds of hormonal contraceptive use (aOR = 0.23, 95%CI: 0.14-0.38) compared to younger women (15-19 years). Likewise, the odds of HCU were low among cohabiting (aOR = 0.66; 95%CI: 0.48-0.89) and previously married women (aOR = 0.67; 95%CI: 0.50-0.91) than never married women.

RESUMEN

PURPOSE: To summarize evidence on levonorgestrel releasing intrauterine system (LNG-IUS) in the treatment of adenomyosis (AM) and to identify potential research gaps. METHODS: Search was conducted in MEDLINE, The Cochrane Library, EMBASE, CBM, CNKI, and Wanfang. We included studies investigating patients with AM treated with LNG-IUS combined with conservative therapy. RESULTS: Thirty-nine studies compared LNG-IUS with other conservative therapeutic drugs. The most common comparison was GnRH-a + LNG-IUS vs. LNG-IUS alone, followed by LNG-IUS vs. mifepristone, expected treatment, and GnRH-a. GnRH-a + LNG-IUS was more beneficial in reducing the intensity of dysmenorrhea than LNG-IUS alone at the 6-month follow-up in patients with an enlarged uterus and moderate to severe dysmenorrhea. Large and well-designed studies are needed to confirm the efficacy of LNG-IUS and GnRH-a on reducing uterine volume at 6-month follow-up. Thirty-two studies investigated LNG-IUS as the postoperative management. The most common comparison was surgical excision + LNG-IUS vs. surgical excision. Results showed VAS scores were lower in the surgical excision + LNG-IUS group than in the surgical excision group at the 1-year follow-up. Evidence on endometrial thickness, quality of life, adverse events and beneficial effect at 3 and 5 years are needed. CONCLUSIONS: Combined GnRH-a and LNG-IUS treatment was more efficacious than LNG-IUS alone for patients with an enlarged uterus and moderate to severe dysmenorrhea. Moreover, LNG-IUS seemed to show potential long-term benefits in postoperative therapy, warranting further meta-analysis for confirmation.

RESUMEN

Hormonal contraceptive (HC) users have a different ovarian hormonal profile compared to eumenorrheic women. Due to the prevalence of HC use amongst sportswomen, there has been increased research efforts to understand their impact on exercise performance. The aim was to audit this research. Studies identified were assessed for HC type, athlete calibre, performance outcome, study design, and quality of methodological control regarding ovarian hormonal profiles. Sixty-eight different HCs were reported across 61 studies. Monophasic combined oral contraceptive (OCP) pills represented 60% of HCs, followed by other pills [34%, phasic-combined, progestogen-only, and un-specified], phasic and long acting reversible contraceptives [5%, vaginal ring, patch, implant, injection, intrauterine system] and unspecified HCs (1%). Eleven percent of participants using HCs were classified as highly trained or elite/international with no participants being classed as world class. Whilst the number of studies involving HCs has increased two-fold over the past decade, the number of studies ranked as gold standard has not increased (HC; 2003-57%, 2011-55%, 2022-43%. OCP; 2003-14%, 2011-17%, 2022-12%). Future research assessing HCs and exercise performance should adopt high-quality research designs and include a broader range of HCs in highly trained to world-class populations to increase the reach and impact of research in this area.

RESUMEN

•The risk of venous thromboembolism (VTE) is not increased in women using long-acting reversible contraceptive methods (LARCs) with progestogens. •Oral contraceptives with levonorgestrel or norgestimate confer half the risk of VTE compared to oral contraceptives containing desogestrel, gestodene or drospirenone. •Progestogen-only pills do not confer an increased risk of VTE. •Women using transdermal contraceptive patches and combined oral contraceptives (COCs) are at an approximately eight times greater risk of VTE than non-users of hormonal contraceptives (HCs), corresponding to 9.7 events per 10,000 women/years. •Vaginal rings increase the risk of VTE by 6.5 times compared to not using HC, corresponding to 7.8 events per 10,000 women/years. •Several studies have demonstrated an increased risk of VTE in transgender individuals receiving hormone therapy (HT). •Hormone therapy during menopause increases the risk of VTE by approximately two times, and this risk is increased by obesity, thrombophilia, age over 60 years, surgery and immobilization. •The route of estrogen administration, the dosage and type of progestogen associated with estrogen may affect the risk of VTE in the climacteric. •Combined estrogen-progesterone therapy increases the risk of VTE compared to estrogen monotherapy. •Postmenopausal HT increases the risk of thrombosis at atypical sites.

RESUMEN

INTRODUCTION: Migration is a rare but serious complication of the etonogestrel contraceptive implant, and little is known about its extent. PURPOSE: To document and characterise cases of etonogestrel contraceptive implant migration in the scientific literature. METHODS: A systematic review of Medline, Embase and Global Health databases was carried out between January 2000 and January 2023 to identify articles presenting implant migrations. Narrative reviews, conference abstracts and articles not written in English or French were excluded. RESULTS: Forty-five articles, mostly published since 2016, were identified (eight case series and 37 case reports), for a total of 148 independent cases of migration: in pulmonary blood vessels (n = 74), in non-pulmonary blood vessels (n = 16) and extravascular (n = 58). Many patients are asymptomatic and migration is often an incidental finding. A non-palpable implant and symptoms related to implant location (intra- or extra-vascular) may be indicative of migration. Inadequate insertion and normal or underweight appear to increase the risk of migration. Scientific societies and authors offer practical strategies to deal with implant migration. CONCLUSION: Professionals who insert and remove contraceptive implants must be adequately trained. They need to be on the lookout for implant migration, and promptly refer patients to appropriate care if migration is suspected.


This systematic review documents and characterises 148 cases of vascular and extravascular etonogestrel contraceptive implant migration. Healthcare professionals must be aware of this rare but serious complication and be adequately trained to insert and remove contraceptive implants.

RESUMEN

Most sexually active women of reproductive age have used contraception, with hormonal methods constituting approximately 40% of contraceptive choices. Among these hormonal options, combined oral contraceptives stand out as the most selected. Within this same demographic, sexual issues are prevalent. Although specific hormonal contraceptives have been implicated in sexual dysfunction among these women, the correlation lacks consistency across studies and varies between different types of hormonal contraception. This article assesses the available literature on the associations between various hormonal contraceptive methods and sexual function and provides practical management insights.

RESUMEN

Many women experience sexual side effects, such as decreased libido, when taking hormonal contraceptives (HCs). However, little is known about the extent to which libido recovers after discontinuing HCs, nor about the timeframe in which recovery is expected to occur. Given that HCs suppress the activities of multiple endogenous hormones that regulate both the ovulatory cycle and women's sexual function, resumption of cycles should predict libido recovery. Here, using a combination of repeated and retrospective measures, we examined changes in sexual desire and partner attraction (among partnered women) across a three-month period in a sample of Natural Cycles users (Survey 1: n = 1596; Survey 2: n = 550) who recently discontinued HCs. We also tested whether changes in these outcomes coincided with resumption of the ovulatory cycle and whether they were associated with additional factors related to HC use (e.g., duration of HC use) or relationship characteristics (e.g., relationship length). Results revealed that both sexual desire and partner attraction, on average, increased across three months after beginning to use Natural Cycles. While the prediction that changes in sexual desire would co-occur with cycle resumption was supported, there was also evidence that libido continued to increase even after cycles resumed. Together, these results offer new insights into relationships between HC discontinuation and women's sexual psychology and lay the groundwork for future research exploring the mechanisms underlying these effects.

RESUMEN

OBJECTIVES: Inherited bleeding disorders may cause heavy menstrual bleeding in women, impacting quality of life and impairing daily and social activities. The levonorgestrel-releasing intrauterine system is a potential treatment for these women, which might reduce menstrual blood loss. STUDY DESIGN: We performed a systematic review and single-arm meta-analysis to examine the levonorgestrel-releasing intrauterine system in women with inherited bleeding disorders and heavy menstrual bleeding. RESULTS: A systematic search on PubMed, Embase and Cochrane yielded 583 results, of which six observational studies (n = 156) met inclusion criteria. Levonorgestrel-releasing intrauterine system use in patients with inherited bleeding disorders and heavy menstrual bleeding was associated with amenorrhea in 60% of patients and a significant increase of 1.40 g/dL in hemoglobin and of 19.75 ng/mL in ferritin levels when comparing post- and pre-treatment levels. The post-treatment mean hemoglobin was 13.32 g/dL and the mean ferritin was 43.22 ng/dL. The rate of intrauterine device expulsion or removal due to mal position was low (13%), as was the need for intrauterine device removal due to lack of efficacy (14%). CONCLUSION: The levonorgestrel-releasing intrauterine system may improve bleeding patterns and quality of life in patients with inherited bleeding disorders and heavy menstrual bleeding. IMPLICATIONS: Women with inherited bleeding disorders could benefit from levonorgestrel-releasing intrauterine system, so its use should be an option for this women.

RESUMEN

The cyclical changes in sex hormones across the menstrual cycle (MC) are associated with various biological changes that may alter resting metabolic rate (RMR) and body composition estimates. Hormonal contraceptive (HC) use must also be considered given their impact on endogenous sex hormone concentrations and synchronous exogenous profiles. The purpose of this study was to determine if RMR and dual-energy X-ray absorptiometry body composition estimates change across the MC and differ compared with HC users. This was accomplished during a 5-week training camp involving naturally cycling athletes (n = 11) and HC users (n = 7 subdermal progestin implant, n = 4 combined monophasic oral contraceptive pill, n = 1 injection) from the National Rugby League Indigenous Women's Academy. MC phase was retrospectively confirmed via serum estradiol and progesterone concentrations and a positive ovulation test. HC users had serum estradiol and progesterone concentrations assessed at the time point of testing. Results were analyzed using general linear mixed model. There was no effect of MC phase on absolute RMR (p = .877), relative RMR (p = .957), or dual-energy X-ray absorptiometry body composition estimates (p > .05). There was no effect of HC use on absolute RMR (p = .069), relative RMR (p = .679), or fat mass estimates (p = .766), but HC users had a greater fat-free mass and lean body mass than naturally cycling athletes (p = .028). Our findings suggest that RMR and dual-energy X-ray absorptiometry body composition estimates do not significantly differ due to changes in sex hormones in a group of athletes, and measurements can be compared between MC phases or with HC usage without variations in sex hormones causing additional noise.

RESUMEN

OBJECTIVES: To measure plasma concentrations of medroxyprogesterone acetate (MPA) in users with epilepsy treated with antiseizure medications and compare these to MPA concentrations in those without epilepsy. STUDY DESIGN: For this multisite cross-sectional study, we obtained a single blood sample from those with epilepsy treated with various antiseizure medications (n = 18) within the week before their next depot medroxyprogesterone injection. Among the participants without epilepsy (n = 20), 10 similarly were scheduled within the week prior to the next injection, and 10 were scheduled at earlier intervals to attempt to balance the time intervals between groups. MPA concentrations were determined by a validated assay. RESULTS: MPA concentrations were similar among those with epilepsy and controls and between groups with and without the use of enzyme-inducing medications. The lowest MPA concentrations, under 0.07 ng/mL, were observed among two of eight using enzyme-inducing antiseizure medications, one of 10 using noninducing medications, and one of 19 controls had concentrations below 0.2 ng/mL. CONCLUSIONS: In this exploratory study, lower MPA concentrations in some participants using enzyme-inducing antiseizure medications suggest a potential interaction that could reduce depot medroxyprogesterone efficacy.

RESUMEN

BACKGROUND: Extensive evidence is available on hormonal contraceptive (HC) use and the risk of a first venous thromboembolism (VTE) event. Despite recommendations to discontinue combined HC (CHC) use, some women continue or start its use after a first VTE. OBJECTIVES: We aimed to evaluate the VTE recurrence risk associated with HC use in premenopausal women. METHODS: Premenopausal women with a first VTE included in the Multiple Environmental and Genetic Assessment of Venous Thrombosis study between 1999 and 2004 were followed for a recurrence until 2010. Data on HC use were available through linkage to the Dutch Foundation for Pharmaceutical Statistics. The risk of recurrence was assessed 1) during anticoagulant therapy and 2) after cessation of anticoagulant therapy. Time-dependent Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% CIs adjusted for age and body mass index at baseline and thromboprophylaxis use during follow-up. RESULTS: Six hundred fifty women were uniquely linked and followed for a total of 3538 person-years (median, 6.1 years), during which 57 VTE recurrences occurred. Five occurred (8.8%) during anticoagulation treatment, with no clear risk difference for CHC use vs nonuse (HR, 0.8; 95% CI, 0.1-8.2). After anticoagulation cessation, CHC use was associated with a 2.4-fold higher risk of recurrence (HR, 2.4; 95% CI, 1.2-5.0) compared with nonuse. Recurrence risk for levonorgestrel-releasing intrauterine device use was similar to that for nonuse (HR, 0.9; 95% CI, 0.3-3.1). CONCLUSION: CHC use after a first VTE is safe during anticoagulant use but substantially increases the risk of a recurrent VTE event in absence of anticoagulant use. This study adds to the evidence regarding the use of a levonorgestrel-releasing intrauterine device as a safe alternative.

RESUMEN

BACKGROUND: Concomitant use of efavirenz-based antiretroviral therapy and a standard-dose etonogestrel contraceptive implant led to 82% lower etonogestrel exposure when compared with women who do not receive antiretroviral therapy. The clinical impact of this reduced exposure is supported by retrospective cohort evaluations that demonstrated higher rates of unintended pregnancies when contraceptive implants were combined with efavirenz. We hypothesized that placement of 2 etonogestrel implants in those taking efavirenz-based antiretroviral therapy could increase etonogestrel exposure and improve measures of contraceptive efficacy. OBJECTIVE: This study compared the rate of ovulation and etonogestrel pharmacokinetics among women on efavirenz-based antiretroviral therapy who received 2 etonogestrel implants (136 mg; double implant group) in comparison with those who received 1 etonogestrel implant (68 mg; control group). STUDY DESIGN: This randomized, open-label study enrolled Ugandan women with regular menstrual periods who were receiving efavirenz-based antiretroviral therapy for the treatment of HIV. Participants were randomized 1:1 to the double implant or control group, and the etonogestrel implant(s) were placed in the same arm at enrollment. All participants used a copper intrauterine device to prevent pregnancy. Ovulation was evaluated by weekly serum progesterone concentrations measured over 4 consecutive weeks at months 3 (weeks 9-12), 6 (weeks 21-24), and 12 (weeks 45-48). Progesterone concentrations >3 ng/mL were interpreted as ovulation. The ovulation rate in each group was compared using Fisher's exact tests for each month and generalized estimating equations over 48 weeks. Plasma was collected at day 3 and weeks 1, 4, 12, 24, 36, and 48 after implant placement and analyzed using a validated liquid chromatography-triple quadrupole mass spectrometry method for etonogestrel. Etonogestrel concentrations were summarized as median (interquartile range) and compared between groups by geometric mean ratio with 90% confidence intervals. RESULTS: All participants (n=72) were cisgender Ugandan women with a median age of 31 years (interquartile range, 29-36), and 36 participants were enrolled in each study group. Two participants in the control group discontinued the trial; 1 at week 1 because of undetected pregnancy at entry and another at week 45 because of clinically significant depression. There were 47 ovulations over 104 person-months (45%) in 25 of 34 participants in the control group, and 2 ovulations over 108 person-months (2%) in 2 of 36 participants in the double implant group (month 3: 11 [31%] vs 0 [0%]; month 6: 17 [49%] vs 0 [0%]; month 12: 19 [56%] vs 2 [6%], respectively; all P<.001). The odds of ovulation were reduced by 97.7% (95% confidence interval, 90.1-99.5) in the double implant group over 48 weeks. At each time point, etonogestrel concentration was more than 2-fold higher in the double implant group than in the controls (geometric mean ratio, 2.30-2.83) with a geometric mean ratio of 2.83 (90% confidence interval, 1.89-3.35) at week 48. There were no differences in the adverse events between groups and no participant discontinued because of adverse events. CONCLUSION: Over 48 weeks of combined use, placing 2 etonogestrel implants suppressed ovulation and increased plasma etonogestrel exposure when compared with 1 etonogestrel implant among women on efavirenz-based antiretroviral therapy. Doubling the dose of etonogestrel during efavirenz-based antiretroviral therapy could improve contraceptive effectiveness.

RESUMEN

OBJECTIVES: To assess the pharmacokinetics and pharmacodynamics of the etonogestrel (ENG) contraceptive implant when inserted at an alternative scapular site. STUDY DESIGN: We conducted a pilot study of healthy, reproductive-age females who underwent subdermal insertion of an ENG implant over the inferior edge of the nondominant scapula (scapular insertion). We measured serum ENG levels over 1 year at nine time points. Participants completed questionnaires on insertion site and bleeding side effects. We collected photographs and video recordings of insertion and removal techniques. RESULTS: We enrolled five participants (as prespecified), their median age was 26.0 years (range: 19.6-30.3), and median body mass index was 25.0 kg/m2 (range: 22.0-28.0). All serum ENG concentrations remained >90 pg/mL and were within the range of published data for arm insertion of ENG implant at all time points. The mean serum ENG level was 511.7 pg/mL (±168.2) at 1 week and 136.6 pg/mL (±21.8) at 12 months. During the first week after insertion, four of five participants noted insertion site pain with a median pain score of 2 (range 1-3), but all noted resolution by week two. Participants reported variable bleeding patterns consistent with standard ENG implant placement. At the end of the study, all participants reported satisfaction with the implant and would recommend scapular insertion to a friend. CONCLUSIONS: Scapular insertion of the ENG contraceptive implant has similar pharmacokinetics to arm insertion over 1 year of use. This novel, alternative site was well tolerated and demonstrated similar bleeding side effects to standard arm insertion. IMPLICATIONS: Subdermal scapular insertion of the etonogestrel contraceptive implant demonstrated similar pharmacokinetics to arm insertion over 1 year of use. Our pilot data support scapular insertion as an alternative site for ENG contraceptive implants, which could be beneficial for certain patient populations.

Abstract Cervical cancer (CC) is caused by persistent infection of human papillomavirus of high oncogenic risk (hr-HPV); however, several cofactors are important in its carcinogenesis, such as smoking, multiparity, and prolonged use of oral hormonal contraceptives (COCs). Worldwide, 16% of women use COCs, whereas in Brazil this rate is of ~ 30%. The safety and adverse effects of COCs are widely discussed in the literature, including the increase in carcinogenic risk. Due to the existence of several drugs, combinations, and dosages of COCs, it is hard to have uniform information in epidemiological studies. Our objective was to perform a narrative review on the role of COCs use in the carcinogenesis of cervical cancer. Several populational studies have suggested an increase in the incidence of cervical cancer for those who have used COCs for > 5 years, but other available studies reach controversial and contradictory results regarding the action of COCs in the development of CC.


Resumo O câncer cervical (CC) é causado pela infecção persistente pelo papilomavírus humano de alto risco oncogênico (hr-HPV); entretanto, vários cofatores são importantes na sua carcinogênese, como tabagismo, multiparidade e uso prolongado de contraceptivos hormonais orais (COCs). No mundo, 16% das mulheres usam AOCs, enquanto no Brasil essa taxa é de ~ 30%. A segurança e os efeitos adversos dos COCs são amplamente discutidos na literatura, incluindo o aumento do risco carcinogênico. Devido à existência de várias drogas, combinações e dosagens de COCs, é difícil ter informações uniformes em estudos epidemiológicos. Nosso objetivo foi realizar uma revisão narrativa sobre o papel do uso de COCs na carcinogênese do câncer cervical. Vários estudos populacionais têm sugerido aumento da incidência de câncer de colo uterino para aquelas que usam COCs há mais de 5 anos, mas outros estudos disponíveis chegam a resultados controversos e contraditórios quanto à ação dos COCs no desenvolvimento do CCU.

RESUMEN

Objetivo: Analisar o uso dos contraceptivos hormonais em mulheres com asma e a escolha desses métodos contraceptivos para essa população, com avaliação de eventuais repercussões sobre novos episódios de asma e sibilos. Métodos: Foram selecionados estudos longitudinais, ensaios clínicos, revisões sistemáticas e metanálises. As plataformas consultadas foram PubMed, Embase, Cochrane e SciELO, com a utilização dos descritores: "contracepção", "contracepção hormonal", "sistema intrauterino liberador de levonorgestrel" e "asma". Resultados: Dois grandes estudos demonstraram que o uso de contraceptivos hormonais esteve associado à redução do risco de novos episódios de asma. Uma revisão sistemática concluiu que os resultados para o uso de contraceptivos hormonais para mulheres com asma foram mistos, com aumento ou redução dos seguintes riscos: novo episódio de asma e aumento da frequência das crises e dos sibilos. O uso da contracepção hormonal em pacientes obesas portadoras de asma é controverso. Conclusão: Os resultados para o uso de contraceptivos hormonais em mulheres com asma são inconsistentes, com relatos de aumento ou de redução do risco de novos episódios. O uso do método contraceptivo deve ser discutido individualmente, levando-se em consideração outros fatores de risco associados e o desejo da mulher. A paciente deverá ser orientada se houver piora dos sintomas clínicos de asma na vigência do uso de qualquer método contraceptivo hormonal.


Objective: To analyze the use of hormonal contraceptives in women with asthma and the choice of this contraceptive method for this population, evaluating possible repercussions on new episodes of asthma and wheezing. Methods: Longitudinal studies, clinical trials, systematic reviews and meta-analyses were selected. Platforms consulted: PubMed, Embase, Cochrane, SciELO, using the descriptors: "contraception", "hormonal contraception", "levonorgestrel-releasing intrauterine system" and "asthma". Results: Two large studies demonstrated that the use of hormonal contraceptives was associated with a reduced risk of new episodes of asthma. A systematic review concluded that the results for the use of hormonal contraceptives for women with asthma were mixed, with increased or decrease in the following risks: new asthma episodes, increased frequency and wheezing. The use of hormonal contraception in obese patients with asthma is controversial. Conclusion: The results for the use of hormonal contraceptives in women with asthma are inconsistent, with reports of increased or reduced risk of new episodes. The use of the contraceptive method should be discussed individually, taking into account other associated risk factors and the woman's desire. The patient will be advised if there is a worsening of the clinical symptoms of asthma while using any hormonal contraceptive method.
