RESUMO

BACKGROUND: The etonogestrel contraceptive implant is currently approved by the United States Food and Drug Administration (FDA) for the prevention of pregnancy up to 3 years. However, studies that suggest efficacy up to 5 years. There is little information on the prevalence of extended use and the factors that influence clinicians in offering extended use. We investigated clinician perspectives on the barriers and facilitators to offering extended use of the contraceptive implant. METHODS: Using the Consolidated Framework for Implementation Research (CFIR), we conducted semi-structured qualitative interviews. Participants were recruited from a nationwide survey study of reproductive health clinicians on their knowledge and perspective of extended use of the contraceptive implant. To optimize the diversity of perspectives, we purposefully sampled participants from this study. We used content analysis and consensual qualitative research methods to inform our coding and data analysis. Themes arose deductively and inductively. RESULTS: We interviewed 20 clinicians including advance practice clinicians, family medicine physicians, obstetrician/gynecologist and complex family planning sub-specialists. Themes regarding barriers and facilitators to extended use of the contraceptive implant emerged. Barriers included the FDA approval for 3 years and clinician concern about liability in the context of off-label use of the contraceptive implant. Educational materials and a champion of extended use were facilitators. CONCLUSIONS: There is opportunity to expand access to extended use of the contraceptive implant by developing educational materials for clinicians and patients, identifying a champion of extended use, and providing information on extended use prior to replacement appointments at 3 years.

RESUMO

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.

RESUMO

BACKGROUND: Successful efforts to encourage uptake of subdermal contraceptive implants, with a lifespan of three to five years, necessitate planning to ensure that quality removal services are available when desired. In Burkina Faso, implant use has tripled over the past 8 years and now comprises almost half of the contraceptive method mix. Population Monitoring for Action (PMA) surveys identified barriers to obtaining quality removal when desired, particularly when the implant is not palpable, or providers lack needed skills or supplies. The Expanding Family Planning Choices (EFPC) project supported ministries of health in four countries with evaluation and strengthening of implant removal services. METHODS: An implant removal landscape assessment was conducted at 24 health facilities in three regions of Burkina Faso with high implant use that included provider observations of implant removal, interviews with providers and health facility managers, and facility readiness surveys. The project used landscape data to mobilize stakeholders through a series of participatory workshops to develop a collaborative roadmap and commit to actions supporting quality implant removals. RESULTS: Landscape findings revealed key gaps in provision of quality removal services, including high levels of provider confidence for implant insertion and removal (82% and 71%, respectively), low competence performing simple and difficult removals (19.2% and 11.1%, respectively), inadequate supplies and equipment (no facilities had all necessary materials for removal), lack of difficult removal management systems, and a lack of standard data collection tools for removal. Exposure to the data convinced stakeholders to focus on removals rather than expanding insertion services. While not all roadmap commitments were achieved, the process led to critical investments in quality implant removals. CONCLUSION: Landscape data revealed that facilities lack needed supplies and equipment, and providers lack skills needed to perform quality implant removals, limiting client reproductive choice. Disseminating this data enabled stakeholders to identify and commit to evidence-based priority actions. Stakeholders have since capitalized on program learnings and the roadmap, including following MOH guidance for implant removal supplies and health provider training. Our experience in Burkina Faso offers a replicable model of how data can direct collective action to improve quality of contraceptive implant removals.

RESUMO

BACKGROUND: Nexplanon implants are a common hormonal contraceptive modality. Though rare, these devices can embolize into the injured wall of the basilic vein, through the right heart, and finally wedge itself into a pulmonary artery. With adherence to the arterial wall over time, it becomes less amenable to endovascular retrieval. Patients may present with symptoms mimicking a pulmonary embolism, or without any symptoms at all. In asymptomatic cases, endovascular retrieval and/or surgery is required when patients wish to begin having children prior to biological inactivity. The current literature showed as little as nine case reports detailing lung tissue removal in the aim of reversing a patient's implanted contraceptive device. CASE PRESENTATION: A 22-year-old asymptomatic active-duty Caucasian female presented for elective outpatient Nexplanon removal. The suspicion of possible implant migration arose when it was discovered to be non-palpable in her left arm. After plain film x-rays failed to localize the implant, a chest x-ray and follow-up Computed Tomography (CT) scan revealed that the Nexplanon had migrated to a distal branch of the left pulmonary artery. Due to the patient's strong desires to begin having children, the decision was made for removal. Initial endovascular retrieval failed due to Nexplanon encapsulation within the arterial wall. Ultimately, the patient underwent a left video-assisted thoracoscopic surgery (VATS) for exploration and left lower lobe basilar S7-9 segmentectomy, which successfully removed the Nexplanon. CONCLUSIONS: Implanted contraceptive devices can rarely result in migration to the pulmonary vasculature. These radiopaque devices are detectable on imaging studies if patients and clinicians are unable to palpate them. An endovascular approach should be considered first to spare lung tissue and avoid chest-wall incisions, but can be complicated by encapsulation and adherence to adjacent tissue. A VATS procedure with single-lung ventilation via a double-lumen endotracheal tube allows surgeons to safely operate on an immobilized lung while anesthesiologists facilitate single-lung ventilation. This patient's case details the uncommon phenomenon of Nexplanon migration, and the exceedingly rare treatment resolution of lung resection to remove an embolized device.

RESUMO

BACKGROUND: Contraceptive use has complex effects on sexual behaviour and mood, including those related to reduced concerns about unintended pregnancy, direct hormonal effects and effects on endogenous sex hormones. We set out to obtain robust evidence on the relative effects of three contraceptive methods on sex behaviours, which is important for guiding contraceptive choice and future contraceptive developments. METHODS: This is a secondary analysis of data from the Evidence for Contraceptive Options and HIV Outcomes (ECHO) randomized trial in which 7,829 HIV-uninfected women from 12 sites in Eswatini, Kenya, South Africa and Zambia seeking contraception were randomly assigned to intramuscular depot-medroxyprogesterone acetate (DMPA-IM), the copper intrauterine device (Cu-IUD) or the levonorgestrel (LNG) implant. Data collected for 12 to 18 months using 3-monthly behavioural questionnaires that relied on recall from the preceding 3 months, were used to estimate relative risk of post-baseline sex behaviours, as well as sexual desire and menstrual bleeding between randomized groups using modified Poisson regression. RESULTS: We observed small but generally consistent effects wherein DMPA-IM users reported lower prevalence of specified high risk sexual behaviours than implant users than Cu-IUD users (the '>' and '<' symbols indicate statistically significant differences): multiple sex partners 3.6% < 4.8% < 6.2% respectively; new sex partner 3.0% < 4.0% <5.3%; coital acts 16.45, 16.65, 17.12 (DMPA-IM < Cu-IUD); unprotected sex 65% < 68%, 70%; unprotected sex past 7 days 33% <36%, 37%; sex during vaginal bleeding 7.1%, 7.1% < 8.9%; no sex acts 4.1%, 3.8%, 3.4% (DMPA-IM > Cu-IUD); partner has sex with others 10% < 11%, 11%. The one exception was having any sex partner 96.5%, 96.9% < 97.4% (DMPA-IM < Cu-IUD). Decrease in sexual desire was reported by 1.6% > 1.1% >0.5%; amenorrhoea by 49% > 41% >12% and regular menstrual pattern by 26% <35% < 87% respectively. CONCLUSIONS: These findings suggest that women assigned to DMPA-IM may have a modest decrease in libido and sexual activity relative to the implant, and the implant relative to the Cu-IUD. We found more menstrual disturbance with DMPA-IM than with the implant (and as expected, both more than the Cu-IUD). These findings are important for informing the contraceptive choices of women and policymakers and highlight the need for robust comparison of the effects of other contraceptive methods as well.

RESUMO

To evaluate gene expression associated with unfavorable vaginal bleeding in users of the Etonogestrel (ENG) contraceptive implant. Prospective study involving 100 women who intended to use the ENG implant. Exclusion criteria included abnormal uterine bleeding, inability to attend a 1-year follow-up, and implant removal for reasons unrelated to vaginal bleeding or loss of follow-up. We obtained endometrial biopsies before implant placement and assessed the expression of 20 selected genes. Users maintained a uterine bleeding diary for 12 months post-implant placement. For statistical analysis, we categorized women into those with or without favorable vaginal bleeding at 3 and 12 months. Women with lower CXCL1 expression had a 6.8-fold increased risk of unfavorable vaginal bleeding at 3 months (OR 6.8, 95% CI 2.21-20.79, p < 0.001), while those with higher BCL6 and BMP6 expression had 6- and 5.1-fold increased risks, respectively. By the 12-month follow-up, women with lower CXCL1 expression had a 5.37-fold increased risk of unfavorable vaginal bleeding (OR 5.37, 95% CI 1.63-17.73, p = 0.006). Women with CXCL1 expression < 0.0675, BCL6 > 0.65, and BMP6 > 3.4 had a higher likelihood of experiencing unfavorable vaginal bleeding at 3 months, and CXCL1 < 0.158 at 12 months. Users of ENG contraceptive implants with elevated BCL6 and BMP6 expression exhibited a higher risk of breakthrough bleeding at the 3-month follow-up. Conversely, reduced CXCL1 expression was associated with an elevated risk of bleeding at both the 3 and 12-month follow-ups.

RESUMO

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.

RESUMO

The wide array of polydimethylsiloxane (PDMS) variants available on the market, coupled with the intricate combination of additives in silicone polymers, and the incomplete understanding of drug release behavior make formulation development of levonorgestrel intrauterine systems (LNG-IUSs) formidable. Accordingly, the objectives of this work were to investigate the impact of excipients on formulation attributes and in vitro performance of LNG-IUSs, elucidate drug release mechanisms, and thereby improve product understanding. LNG-IUSs with a wide range of additives and fillers were prepared, and in vitro drug release testing was conducted for up to 12 months. Incorporating various additives and/or fillers (silica, silicone resins, silicone oil, PEG, etc.) altered the crystallization kinetics of the crosslinked polymer, the viscosity, and the microstructure. In addition, drug-excipient interactions can occur. Interestingly, additives which increased matrix hydrophobicity and hindered PDMS crystallization facilitated dissolution and permeation of the lipophilic LNG. The influence of additives and lubricants on the mechanical properties of LNG-IUSs were also evaluated. PDMS chemical substitution and molecular weight were deemed to be most critical polymer attributes to the in vitro performance of LNG-IUSs. Drugs with varying physicochemical characteristics were used to prepare IUSs, modeling of the release kinetics was performed, and correlations between release properties and the various physicochemical attributes of the model drugs were established. Strong correlations between first order release rate constants and both drug solubility and Log P underpin the partition and diffusion-based release mechanisms in LNG-IUSs. This is the first comprehensive report to provide a mechanistic understanding of material-property-performance relationships for IUSs. This work offers an evidence-based approach to rational excipient selection and tailoring of drug release to achieve target daily release rates in vivo. The novel insights gained through this research could be helpful for supporting development of brand and generic IUS products as well as their regulatory assessment.

RESUMO

BACKGROUND: Robust information on relative effects of hormonal contraceptives on endogenous androgens is important for understanding beneficial and adverse effects, method choice and development of new methods. METHODS: In this ancillary study at the East London, South Africa site of the ECHO multicentre randomized trial, we compared effects of three contraceptive methods on serum androgen levels among contraceptive users aged 18 to 35 years. Participants were allocated by centrally-managed randomization to open label depot medroxyprogesterone acetate (DMPA-IM), copper intrauterine device (IUD) or levonorgestrel implant. The primary outcome was free testosterone at 6 months. RESULTS: We analysed stored baseline and 6-month serum samples in 398/615 participants (DMPA-IM 131/205, IUD 135/205 and implant 132/205). Median testosterone levels at baseline were DMPA-IM 0.82, IUD 0.9 and implant 0.87 nmol/L; at 6 months, DMPA 0.68 (lower than IUD, mean percentage difference 28.35, (p <  0.001), IUD 0.86 (unchanged) and implant 0.66, lower than IUD, mean percentage difference - 22.98, p <  0.001). Median SHBG levels at baseline were DMPA 52.4, IUD 50.5 and implant 55.75 nmol/L; at 6 months, DMPA 40.65, lower than IUD (mean percentage difference 21.19, p = 0.005), IUD 49.1 (unchanged), and implant 23.35 nmol/L, lower than IUD (mean percentage difference - 50.04, p <  0.001 and than DMPA (mean percentage difference - 39.45, p <  0.001). Free testosterone levels at baseline were DMPA 10, IUD 12 and implant 11 pmol/L; at 6 months, DMPA 11, less than IUD (mean percentage difference 13.53, p = 0.047), IUD 12 and implant 14, higher than IUD (mean percentage difference 14.15, p = 0.038) and than DMPA, (mean percentage difference 29.60, p < 0.001). CONCLUSIONS: This is the first randomized trial to show lower SHBG and higher free testosterone with the levonorgestrel implant than with DMPA, and contrasts with reports of increased SHBG with combined oral ethinyl estradiol/levonorgestrel use, and reduced androgens (and impaired sexual function) reported with the etonorgestrel implant. The higher free testosterone with the LNG implant might improve sexual function, mood and bone health as well as increasing side-effects such as acne and hirsutism, and is consistent with the greater sexual activity (with respect to multiple sex partners, new sex partner and unprotected sex) with the implant compared with DMPA documented in the ECHO study. ECHO TRIAL REGISTRATION: ClinicalTrials.gov , number NCT02550067 15/09/2015. Contraception, or family planning, is central to the role of women in societies. It is most important to have accurate information on the relative side-effects of various contraceptive options in order to empower women to make informed choices regarding their preferred method. Hormonal contraceptives contain various forms of the female sex hormones, estrogens and/or progestogens. These hormones have direct effects on the users, as well as modifying the levels of the users' own circulating sex hormones, both the 'female' and the 'male' sex hormones (androgens). In this study, consenting participants requesting contraception, were allocated randomly to receive either depot medroxyprogesterone acetate (DMPA-IM) a 3-monthly progestogen injection, the copper intrauterine device (IUD), a non-hormonal contraceptive inserted within the womb, or the levonorgestrel implant, a device placed under the skin which releases a progestogen for 5 years. We measured the participants' androgen levels after 6 months, and found for the first time that the active form of testosterone (free testosterone) was 29% higher with the implant than with DMPA-IM. The level with the IUD was intermediate, and significantly different from the other two methods. This finding is relevant to the effects experienced by users of these methods, because free testosterone has effects on sexual function, bone health and mood, as well as on conditions such as acne and hair distribution patterns.

RESUMO

OBJECTIVES: Evaluate the safety of Ovaprene, an investigational nonhormonal vaginal contraceptive designed for monthly use. STUDY DESIGN: Open-label, multicenter study enrolling heterosexually-active women with previous permanent contraception who underwent assessments during five menstrual cycles: baseline postcoital test cycle, diaphragm postcoital test cycle, Ovaprene safety cycle, and two Ovaprene postcoital test cycles. Safety outcomes included treatment-emergent adverse events, systemic laboratory findings, pelvic examinations, colposcopies, Nugent scores, determination of community state types of vaginal microbiota, and anti-Escherichia coli activity and inflammatory markers in cervicovaginal fluids. RESULTS: We enrolled 38 participants. Of these, 33 used Ovaprene and completed 77 Ovaprene cycles. The most common product-related urogenital treatment-emergent adverse events were bacterial vaginosis and vaginal odor. The frequency of transitioning from Lactobacillus-dominated community state type to community state type IV (not Lactobacillus-dominated) was similar before Ovaprene use and afterwards. Mean Nugent scores were <4 at each visit without a discernible upward trend. Inflammatory markers showed wide variation but no upward trend, and E. coli inhibitory activity of cervical secretions did not change. We found no Staphylococcus aureus, the causative agent in toxic shock syndrome, on used Ovaprenes or in vaginal samples. No clinically important changes in systemic laboratory findings, pelvic examinations, or colposcopies occurred during Ovaprene use. CONCLUSIONS: Ovaprene use did not result in cervicovaginal irritation or adverse effects on resident vaginal microbiota and did not impact transitions from a Lactobacillus-dominated community state type to community state type IV. IMPLICATIONS: The finding that the use of Ovaprene, an investigational monthly user-controlled nonhormonal vaginal contraceptive, does not appear to result in adverse changes in vaginal health during short-term use supports further evaluation of the contraceptive potential of the device.

RESUMO

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.

RESUMO

PURPOSE: The purpose of this study was to analyse the impact of embedment of side arms of the levonorgestrel 52 mg intrauterine device (LNG-IUD) in the myometrium (assessed by three-dimensional transvaginal ultrasound (3D-TVUS)) on uterine bleeding and pain. MATERIALS AND METHODS: We performed a prospective cohort study in a large Dutch teaching hospital between February 2015 and December 2016. Participants over 18 years of age who selected a LNG-IUD for contraception or because of heavy menstrual bleeding were eligible for inclusion. Six weeks after insertion, a 3D-TVUS was performed to diagnose embedment of the side arms. At that moment participants filled in questionnaires about their bleeding pattern and pelvic pain. Menstruation patterns 'no bleeding', 'regular menstruation', 'sometimes a day of spotting (maximum once a week)' were classified as favourable bleeding pattern. Menstruation patterns 'heavy menstrual bleeding', 'several days a week bleeding days', 'several days a week spotting days', 'continuously spotting', and 'completely irregular cycle' were classified as unfavourable bleeding pattern. Univariate and multivariate logistic regression analysis was used to calculate odds ratios (OR) and 95 %-confidence intervals (CI). The multivariate analysis included endometrial thickness, reason for insertion and parity. The analysis of pelvic pain additionally included previous insertion. RESULTS: A total of 220 participants were evaluated for the study of whom 176 returned the questionnaires. Embedment of the side arms was observed in 43 of the 176 responding participants (24.4 %). Favourable bleeding pattern was reported by 25/43 (58.1 %) participants with embedment and 53/133 (39.8 %) participants without embedment (ORadj 1.8, 95 % CI 0.9-3.9). Pelvic pain was reported by 4/43 (9.3 %) participants with embedment and 24/133 (18.1 %) participants without embedment (ORadj 0.3; CI 0.1-1.2). CONCLUSIONS: The present study suggests that embedment of the side arms of the LNG-IUD in the myometrium assessed by 3D-TVUS is not associated with a unfavourable bleeding pattern nor pelvic pain six weeks after insertion.

RESUMO

BACKGROUND: Observational data suggest lower HIV risk with norethisterone enanthate (NET-EN) than with depo-medroxyprogesterone acetate intramuscular (DMPA-IM) injectable contraceptives. If confirmed, a switch between these similar injectable methods would be programmatically feasible and could impact the trajectory of the HIV epidemic. We aimed in this paper to investigate the effects of DMPA-IM and NET-EN on estradiol levels, measures of depression and sexual activity and menstrual effects, relevant to HIV risk; and to ascertain whether these measures are associated with estradiol levels. METHODS: This open-label trial conducted at two sites in South Africa from 5 November 2018 to 30 November 2019, randomized HIV-negative women aged 18-40 to DMPA-IM 150 mg intramuscular 12-weekly (n = 262) or NET-EN 200 mg intramuscular 8-weekly (n = 259). Data were collected on hormonal, behavioral and menstrual effects at baseline and at 25 weeks (25W). RESULTS: At 25W, median 17ß estradiol levels were substantially lower than at baseline (p<0.001) for both methods: 76.5 pmol/L (interquartile range (IQR) 54.1 to 104.2) in the DMPA-IM group (n = 222), and 69.8 pmol/L (IQR: 55.1 to 89.3) in the NET-EN group (n = 225), with no statistical difference between the two methods (p = 0.450). Compared with DMPA-IM, NET-EN users reported significantly less amenorrhoea, fewer sexual acts, fewer users reporting at least one act of unprotected sex, more condom use with steady partner, more days with urge for sexual intercourse, more days feeling partner does not love her, and more days feeling sad for no reason. We did not find a clear association between estradiol levels and sexual behavior, depression and menstrual effects. Behavioral outcomes suggest less sexual exposure with NET-EN than DMPA-IM. The strength of this evidence is high due to the randomized study design and the consistency of results across the outcomes measured. CONCLUSIONS: Estradiol levels were reduced to postmenopausal levels by both methods. Secondary outcomes suggesting less sexual exposure with NET-EN are consistent with reported observational evidence of less HIV risk with NET-EN. A randomized trial powered for HIV acquisition is feasible and needed to answer this important question. TRIAL REGISTRATION: PACTR 202009758229976.

RESUMO

High rates of unplanned pregnancies persist despite pharmacological developments and advancements in contraceptive methods. Here, we demonstrate that the etonogestrel-releasing subdermal contraceptive implant (IMP-ETN) may be an appropriate and cost-effective alternative to levonorgestrel-releasing intrauterine systems (LNG-IUSs) for women in Brazil. For our pharmacoeconomic analysis, we reviewed the literature on IMP-ETN regarding its acceptance, eligibility criteria, choice, relations with age, adverse events and, finally, the unmet need in the fee-for-service private healthcare sector. We considered qualitative observations in combination with quantitative analysis and performed a deterministic sensitivity analysis to investigate whether this technology can be self-sustainable over a period of five years. The target population for this analysis comprised 158,696 women. Compared with the continued use of LNG-IUSs, adopting the IMP-ETN can result in a cost avoidance of $ 7.640.804,02 in the first year and $ 82,455,254.43 in five years. Disseminating information among physicians will promote this change and strengthen the potential cost avoided by private health system payers. These savings can be used to improve other healthcare programs and strategies. Moreover, the principles of care can be promoted by improving and adapting healthcare systems and expanding treatment and follow-up strategies. This would also provide support to women's reproductive rights and improve their quality of life. Our results suggest that the IMP-ETN has a favorable cost-effectiveness profile. Given all its advantages and negative incremental cost impact over a period of five years, the IMP-ETN may be a more favorable alternative to LNG-IUSs. Therefore, it should be offered to beneficiaries with a private healthcare plan. This analysis overcomes previous barriers to the use of cost-benefit models, and our results may help balance decision-making by policymakers, technical consultants, and researchers.

RESUMO

AIM: Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disease in the world. There are known triggers to initiate an FMF attack, yet potential effects of intrauterine devices (IUD) in women of reproductive age have not been evaluated before. METHOD: Consecutive female patients with FMF who ever used IUD over the age of 18 were enrolled. Female patients with FMF were sub grouped according to the type of IUD they use. FMF attack frequency, severity, duration, presence of dysmenorrhea, severity of dysmenorrhea, having attacks during menstruation before and after IUD use were questioned. Demographic and clinical data were collected from hospital database. RESULTS: When all patients with IUD use were evaluated, it was found that the frequency of attacks increased after IUD insertion at 3rd and 12th months (median [min-max] attack frequency at 3rd month, 1 (0-3) vs 1 (0-6), p = 0.002, median [min-max] attack frequency at 12th month, 2 (0-12) vs 3.5 (0-18), p = 0.028). Attack severity measured by VAS pain was also significantly increased. Attack duration and menstrual pain was similar before and after IUD use. Attack frequency at 3rd and 12th months, attack severity and menstrual pain was all increased significantly in Cu-IUD users, whereas none of these parameters deteriorated in LNG-IUD group. CONCLUSION: IUD use, especially Cu-IUD, may increase the frequency and severity of attacks in female patients with FMF. Clinicians may benefit from considering LGN-IUD if IUDs are preferred as contraception in women of childbearing age with FMF.

RESUMO

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.

RESUMO

BACKGROUND: Induced abortion can seriously harm the physical and mental health of adolescent women. Long-acting reversible contraception (LARC) can effectively reduce unplanned pregnancies and prevent repeated abortions among adolescents. This study aimed to analyse the factors affecting the choice of LARC among adolescents in Chongqing of China. METHODS: A total of 555 adolescents who underwent induced abortions for unplanned pregnancies between January 2019 and October 2021 were selected as study subjects. Logistic regression analysis was used to determine the factors affecting adolescent LARC choices following induced abortions. RESULTS: The factors that affected adolescent LARC choices included an average monthly income ≥ ¥3000 (OR = 3.432, 95% CI: 1.429∼8.244), history of previous abortions (OR = 3.141, 95% CI: 1.632∼6.045), worrying about unplanned pregnancy (OR = 0.365, 95% CI: 0.180∼0.740), parental support for using LARC (OR = 3.549, 95% CI: 1.607∼7.839), sexual partners' support for using LARC (OR = 2.349, 95% CI: 1.068∼5.167), concerns about using LARC (OR = 0.362, 95% CI: 0.176∼0.745), and willingness to use free IUDs (OR = 13.582, 95% CI: 7.173∼25.717). CONCLUSION: Cost is one of the factors affecting LARC choices. Parents and sexual partners may play important role in the choice of LARC.


The study analysed the choice of contraceptive methods and the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents in Chongqing, China. The results showed that the income level, history of previous abortions, extent of worrying about unplanned pregnancy, parents' and sexual partners' attitude towards to use long-acting reversible contraception methods, concerns about using long-acting reversible contraception methods, and willingness to use free intrauterine devices were the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents.

RESUMO

PURPOSE: The Kyleena™ Satisfaction Study (KYSS) provided the first data on 19.5 mg levonorgestrel-releasing intrauterine system (LNG-IUS-19.5 mg) use in routine clinical practice. Here we report results from the German participants in KYSS. METHODS: This prospective, observational, single-arm cohort study recruited women who independently chose to use LNG-IUS-19.5 mg during routine counseling in Germany. Overall satisfaction and bleeding profile satisfaction, continuation rates, and safety profile were evaluated at 12 months or premature end of observation (EoO). RESULTS: In the German study population, LNG-IUS-19.5 mg placement was attempted in 508 women and successful in 506 women. Mean age was 32.3 years, and 60.0% (n = 305/508) were parous. Placement was considered easy and associated with no more than mild pain, even in younger and nulliparous participants. Of those with satisfaction data available, 87.6% (n = 388/443) were satisfied with LNG-IUS-19.5 mg at 12 months/EoO. Satisfaction was similar for parous (86.9%, n = 238/274) and nulliparous (88.8%, n = 150/169) women, and was independent of age, prior contraceptive method, or reason for choosing LNG-IUS-19.5 mg. Most participants (73.6%, n = 299/406) were also satisfied with their bleeding profile at 12 months/EoO, independent of parity, age, prior contraceptive method, presence of amenorrhea or dysmenorrhea severity. The 12-month continuation rate was 84.1% (n = 427/508). Most discontinuations were due to loss to follow-up (8.5%, n = 43/508) or treatment-emergent adverse events (TEAEs) (4.7%, n = 24/508). TEAEs were reported in 12.6% (n = 64) of participants, with 9.3% (n = 47) considered to have an LNG-IUS-19.5 mg-related TEAE. CONCLUSION: Our real-world findings on LNG-IUS-19.5 mg use in German KYSS participants reflected its suitability for a broad population, including young and nulliparous women. CLINICAL TRIAL REGISTRATION: NCT03182140 (date of registration: June 2017).

RESUMO

OBJECTIVE: Clinical factors related to development of amenorrhea in adolescents with the etonogestrel contraceptive implant are not well-understood. The purpose of this study is to describe what baseline clinical characteristics are associated with amenorrhea in adolescents with a contraceptive implant 12 months after placement. STUDY DESIGN: This retrospective cohort study included 252 post-menarchal individuals aged 12-22 years with a contraceptive implant placed between 2016-2020. Data abstracted at insertion, three months post-insertion, and 12 months post-insertion included demographics, baseline bleeding pattern, prior contraception use, post-insertion bleeding pattern, and method discontinuation. We assessed possible predictive characteristics of our outcomes using bivariate and multivariable logistic regression analyses. RESULTS: Twenty nine percent of patients were amenorrheic 12 months after placement. Patients who were amenorrheic at 12 months were more likely to be obese (41.1% vs 24.6%, p = 0.01), to have been amenorrheic prior to implant insertion (16.9% vs 5.4%, p < 0.01, to have used hormonal contraception immediately prior to insertion (42.5% vs 26.3%, p = 0.01), to have had the most recent contraceptive method being another implant (12.3% vs 3.6%, p = 0.02), and to have developed amenorrhea within three months after placement (22.2% vs 12.6%, p < 0.01). After multivariable regression analysis, only obesity (adjusted odds ratio [aOR] 2.2 95% CI 1.1-4.2) and amenorrhea at three months (aOR 3.6, CI 1.1-11.5) were associated with amenorrhea at 12 months. CONCLUSION: Obesity and early amenorrhea were associated with 12-month amenorrhea in adolescents using the etonogestrel subdermal implant. Understanding this can help with contraceptive method selection and counseling for patients and providers. IMPLICATIONS: Obesity and early amenorrhea with the etonogestrel contraceptive implant are associated with longer-term amenorrhea in adolescents using this method. These findings can aid providers with method selection and pre-insertion decision-making for adolescents considering contraceptive implant use, as well as continued counseling after placement.

RESUMO

OBJECTIVE: To evaluate gene expression associated with vaginal bleeding in the 52-mg hormonal intrauterine device (IUD) users. MATERIALS AND METHODS: We conducted a prospective study involving 100 women seeking to use the 52-mg hormonal IUD for contraception. We excluded women with a history or current condition of abnormal uterine bleeding and who were unable to attend a 1-year follow up. Women who expelled the device, removed it for reasons unrelated to vaginal bleeding, or were lost to follow up were discontinued. We collected endometrial biopsies immediately before IUD placement and assessed 20 selected genes using reverse transcription quantitative polymerase chain reaction. Users maintained a uterine bleeding diary for 12 months following IUD insertion. For statistical analysis, participants were categorized into groups with or without vaginal bleeding at 3 and 12 months. RESULTS: Women with elevated CXCL9 expression had an 8.15-fold higher likelihood of experiencing vaginal bleeding at 3 months (odds ratio [OR] 8.15, 95% confidence interval [CI] 2.24-29.61, P = 0.001). At 12 months of follow up, women with increased TIMP1 expression had a 2.74-fold higher chance of experiencing vaginal bleeding (OR 2.74, 95% CI 1.08-6.95, P = 0.033). CXCL9 ≥ 1.5 and IL17A ≥ 0.68 were associated with a higher probability of vaginal bleeding at 3 months, while TIMP1 levels ≥0.943 were linked to an increased risk of bleeding at 12 months. CONCLUSION: Users of the 52-mg hormonal IUD with elevated relative CXCL9 expression face an increased risk of vaginal bleeding at 3-month follow up, whereas those with heightened TIMP1 expression are more likely to experience vaginal bleeding at 12 months.
