RESUMO

BACKGROUND: The commonly used combined hormonal contraceptives with progestins and ethinylestradiol are associated with an increased risk of ischemic stroke (IS). Progestin-only preparations, including levonorgestrel-releasing intrauterine devices (LG-IUDs), are not associated with an increased risk, and in smaller studies, the risk is even reduced. The risk of intracerebral hemorrhage (ICH) has never been investigated. We studied the risk of IS and ICH in women using LG-IUDs compared with women not using hormonal contraceptives. METHODS: In this Danish historical cohort study (2004-2021), we followed nonpregnant women (18-49 years) registering incident IS and ICH in relation to use of LG-IUDs/nonuse of hormonal contraceptives utilizing Danish high-quality registries with nationwide coverage. Poisson regression models adjusting for age, ethnicity, education, calendar year, and medication use for risk factors were applied. RESULTS: A total of 1 681 611 nonpregnant women contributed 11 971 745 person-years (py) of observation. Mean age at inclusion was 30.0 years; mean length of follow-up was 7.1 years; 2916 women (24.4 per 100 000 py) had IS; 367 (3.1 per 100 000 py) had ICH. Of these, 364 784 were users of LG-IUD contributing 1 720 311 py to the investigation; mean age at start of usage was 34.6 years. Nonusers of hormonal contraceptives contributed 10 251 434 py; mean age at inclusion was 30.0 years. The incidence rate of IS/ICH among LG-IUD users was 19.2/3.0 and among nonusers, it was 25.2/3.1 per 100 000 py. After adjustment, incidence rate ratio for IS was 0.78 (CI, 0.70-0.88), and for ICH it was 0.94 (CI, 0.69-1.28). CONCLUSIONS: The use of LG-IUD was associated with a 22% lower incidence rate of IS without raising the incidence rate of ICH. The finding raises the question of whether levonorgestrel, in addition to its contraceptive properties, could have the potential to prevent IS.

RESUMO

Contraception is a practice with extensive and complicated social and scientific histories. From cycle tracking, to the very first prescription contraceptive pill, to now having over-the-counter contraceptives on demand, family planning is an aspect of healthcare that has undergone and will continue to undergo several transformations through time. This review provides a comprehensive overview of current reversible hormonal and non-hormonal birth control methods as well as their mechanism of action, safety, and effectiveness specifically for individuals who can become pregnant. Additionally, we discuss the latest Food and Drug Administration (FDA)-approved hormonal method containing estetrol and drospirenone that has not yet been used worldwide as well as the first FDA-approved hormonal over-the-counter progestin-only pills. We also review available data on novel hormonal delivery through microchip, microneedle, and the latest FDA-approved non-hormonal methods such as vaginal pH regulators. Finally, this review will assist in advancing female contraceptive method development by underlining constructive directions for future pursuits. Information was gathered from the NCBI and Google Scholars databases using English and included publications from 1900 to present. Search terms included contraceptive names as well as efficacy, safety, and mechanism of action. In summary, we suggest that investigators consider the side effects and acceptability together with the efficacy of contraceptive candidate towards their development.

RESUMO

Depot medroxyprogesterone acetate (DMPA) is an injectable hormonal contraceptive used by millions of women worldwide. However, experimental studies have associated DMPA use with genital epithelial barrier disruption and mucosal influx of human immunodeficiency virus (HIV) target cells. We explored the underlying molecular mechanisms of these findings. Ectocervical biopsies and cervicovaginal lavage (CVL) specimens were collected from HIV-seronegative Kenyan sex workers using DMPA (n = 32) or regularly cycling controls (n = 64). Tissue samples were assessed by RNA-sequencing and quantitative imaging analysis, whereas protein levels were measured in CVL samples. The results suggested a DMPA-associated upregulation of genes involved in immune regulation, including genes associated with cytokine-mediated signaling and neutrophil-mediated immunity. A transcription factor analysis further revealed DMPA-associated upregulation of RELA and NFKB1 which are involved in several immune activation pathways. Several genes significantly downregulated in the DMPA versus the control group were involved in epithelial structure and function, including genes encoding keratins, small proline-rich proteins, and cell-cell adhesion proteins. Pathway analyses indicated DMPA use was associated with immune activation and suppression of epithelium development, including keratinization and cornification processes. The cervicovaginal microbiome composition (Lactobacillus dominant and non-Lactobacillus dominant) had no overall interactional impact on the DMPA associated tissue gene expression. Imaging analysis verified that DMPA use was associated with an impaired epithelial layer as illustrated by staining for the selected epithelial junction proteins E-cadherin, desmoglein-1 and claudin-1. Additional staining for CD4+ cells revealed a more superficial location of these cells in the ectocervical epithelium of DMPA users versus controls. Altered protein levels of SERPINB1 and ITIH2 were further observed in the DMPA group. Identification of specific impaired epithelial barrier structures at the gene expression level, which were verified at the functional level by tissue imaging analysis, illustrates mechanisms by which DMPA adversely may affect the integrity of the genital mucosa.

RESUMO

RESEARCH QUESTION: Do the various forms of hormonal and non-hormonal contraceptives have any association with ovarian stimulation outcomes, such as oocyte yield and maturation, in patients undergoing planned oocyte cryopreservation (POC)? DESIGN: This retrospective cohort study included all patients who underwent POC cycles between 2011 and 2023. The use of types of contraception before a POC cycle was recorded. The study evaluated the median number of cumulus-oocyte complexes obtained after vaginal oocyte retrieval and the proportion of metaphase II oocytes that underwent vitrification among all the cohorts. RESULTS: A total of 4059 oocyte freezing cycles were included in the analysis. Eight types of contraceptive method were recognized in patients undergoing ovarian stimulation: intrauterine device (IUD), copper (n = 84); IUD, levonorgestrel low dose (<52 mg) (n = 37); IUD, levonorgestrel (n = 192); subdermal etonogestrel implant (n = 14); injectable medroxyprogesterone acetate (n = 11); etonogestrel vaginal ring (n = 142); combined oral contraceptive pills (n = 2349); and norelgestromin transdermal patch (n = 10). The control group included patients not using contraceptives or using barrier or calendar methods (n = 1220). Among all the cohorts the median number of cumulus-oocyte complexes retrieved during oocyte retrieval was comparable (P = 0.054), and a significant difference in oocyte maturity rate with median number of vitrified oocytes was found (P = 0.03, P < 0.001, respectively). After adjusting for confounders a multivariate analysis found no association between the type of contraceptive and proportion of metaphase II oocytes available for cryopreservation. CONCLUSIONS: Among the various forms of contraception, none was shown to have an adverse association with oocyte yield or maturation rate in patients undergoing POC.

RESUMO

BACKGROUND: The US Food and Drug Administration-approved segesterone acetate and ethinyl estradiol ring-shaped contraceptive vaginal system, known as Annovera (Sever Pharma Solutions/QPharma, Malmö, Sweden), was inserted and removed under a woman's control for a 21 day in and 7 day out regimen for up to 13 cycles of use. OBJECTIVE: We aimed to describe the patterns of ring expulsion over time, to identify potential predictors of expulsion, and to evaluate the impact of expulsions on method discontinuation and pregnancy risk. STUDY DESIGN: Using data from 2064 participants who were enrolled in 2 multinational phase 3 clinical trials on the use of this contraceptive vaginal system, we examined data from participants' daily diaries for documentation of complete ring expulsion. We modeled the odds of reported expulsions over time with adjustment for background and demographic characteristics using mixed-effects logistic regression models with random intercepts. We compared the probability of continuation between those who did and those who did not report expulsions in the first cycle of use using survival analysis and hazards modeling. To determine if expulsions during the first cycle of use affected the risk for pregnancy, we calculated Pearl Indices. RESULTS: Most participants (75%) never experienced any expulsions during any cycle of use, and 91% to 97% did not experience an expulsion during any 1 cycle. The incidence of expulsion was highest in cycle 1 (9%). The odds of experiencing expulsions decreased by half in cycles 2 to 8 when compared with cycle 1 (0.48; 95% confidence interval, 0.40-0.58), and in cycles 9 to 13, expulsions were about a third of that in cycle 1 (0.32; 95% confidence interval, 0.26-0.41). Of those who did experience expulsions, most (62%-84%) experienced ≤2 expulsions per cycle. Participants from study sites in Latin America vs those in the United States had higher odds of not experiencing an expulsion (odds ratio, 1.95; 95% confidence interval, 1.45-2.63). Women with a higher education level had higher odds of experiencing an expulsion. Notably, parity, age, and body mass index were not associated with expulsion. Participants who experienced any expulsions in cycle 1 were more likely to discontinue use early (hazard ratio, 1.28; 95% confidence interval, 1.14-1.43) than participants who did not have an expulsion. The Pearl Index for participants who had expulsions during cycle 1 was 3.99 (95% confidence interval, 1.29-9.31), which was higher than that among participants who reported no expulsions (Pearl Index, 2.39; 95% confidence interval, 1.61-3.41), but the overlapping confidence intervals indicate that there is not sufficient evidence to demonstrate an association between expulsions and pregnancy risk. CONCLUSION: Expulsions were infrequent overall, decreased with subsequent cycles of use, and were not associated with body mass index or parity. Early discontinuation of product use was higher among participants who experienced an expulsion during cycle 1. Although it is unclear whether pregnancy risk was associated with expulsions, early recognition of expulsions among users may identify those at higher risk for discontinuation and may highlight when enhanced anticipatory counselling and guidance may be advantageous.

RESUMO

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.

RESUMO

BACKGROUND: The levonorgestrel-releasing intrauterine device (LNG-IUD) is widely used for the treatment of menorrhagia, dysmenorrhea, and for contraception. However, the association between the use of LNG-IUD and the risk of site-specific gynecologic and breast cancers remains inconclusive. OBJECTIVE: We aim to address this knowledge gap by investigating whether the use of LNG-IUD is associated with a significant risk of site-specific gynecologic and breast cancers. This will be achieved by accessing the nationwide Swedish Registers, with consideration given to the influence and potential interaction of family history of cancer. STUDY DESIGN: A total of 514,719 women aged 18 to 50 years who have used LNG-IUD between July 2005 and December 2018 were identified from the Swedish Prescribed Drug Register and randomly matched with 1,544,157 comparisons who did not use LNG-IUD at a ratio of 1:3. The propensity score was calculated and matched among women who used LNG-IUD and the matched comparisons. The follow-up period started from the date of the first prescription of LNG-IUD for users as well as for their matched comparisons and ended at the date of diagnosis of gynecologic and breast cancers, date of death from any cause, and the end of the study period, whichever came first. The Cox proportional hazard model with a competing risk analysis was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Additive interaction was calculated as the relative excess risk for interaction, while multiplicative interaction was calculated by including a product term in the regression model. RESULTS: The use of LNG-IUD was associated with a 13% higher risk of breast cancer (adjusted HR, 1.13; 95% CI, 1.10-1.17), a 33% lower risk of endometrial cancer (adjusted HR, 0.67; 95% CI, 0.56-0.80), a 14% lower risk of ovarian cancer (adjusted HR, 0.86; 95% CI, 0.75-0.99), and a 9% reduced risk of cervical cancer (adjusted HR, 0.91; 95% CI, 0.84-0.99) compared to women who did not use LNG-IUD. A significant additive interaction between LNG-IUD use and family history of cancer was observed in breast cancer, indicating a relative 19% excess risk for interaction (P<.002), and 1.63 additional cases per 10,000 person-years. CONCLUSION: The risk of gynecologic and breast cancers exhibits a site-specific effect among LNG-IUD users. It is important to note that the observed effect is small for breast cancer and the results are limited by the observational study design. Clinical recommendations regarding the use of LNG-IUD should carefully weigh its potential benefits and risks. Close monitoring is advisable for the potential development of breast cancer, particularly among women with a family history of breast cancer.

RESUMO

A 17-year-old previously healthy female developed posterior reversible encephalopathy syndrome 1 week after etonogestrel implantation. She had a previous etonogestrel implant removed 4 months prior after unrelenting abdominal pain and hyponatremia with a negative workup for other etiologies, including hypercoagulable disorders and malignancy. This second insertion and resulting hospitalization allowed for the diagnosis of acute intermittent porphyria (AIP) to be confirmed. Progesterone can induce enzymatic activity upstream of porphobilinogen deaminase, the enzyme implicated in AIP, resulting in build-up of toxic metabolites. AIP requires high clinical suspicion for diagnosis but should be considered when hormonal triggers lead to unexplained neurovisceral symptoms.

RESUMO

Injectables are one of the most popular methods of contraception worldwide, particularly in sub-Saharan Africa. An advantage of injectables over shorter-acting methods is that they provide additional flexibility by not requiring re-supply as frequently. However, there is a risk that injectable users may delay their next injection and may therefore have reduced or no protection from pregnancy. In surveys, women may report that they are using contraception in the form of injectables when the time since they had their last injection (more than four months) would imply that they have reduced protection against the risk of pregnancy. We carried out two field studies in urban Malawi, and we record reported injectable contraceptive use while also asking the number of months since women received their last injection. We observe that 13.8 percent of women who report using injectables also report that they received their last injection more than four months ago, and 11 percent report that they received their last injection more than six months ago. Our analysis highlights the need for additional follow-up with women who report using injectables in surveys to confirm whether they are, in fact, using the method effectively.

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: 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

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

AIM: To compare and evaluate the efficacy of the levonorgestrel-releasing intrauterine system (LNG-IUD) and resectoscopy remodeling procedure for intermenstrual bleeding associated with previous cesarean delivery scar defect (PCDS). METHODS: A retrospective comparative study was conducted on patients with PCDS receiving LNG-IUD (levonorgestrel 20 µg/24 h, N = 33) or resectoscopy remodeling (N = 27). Treatment outcomes were compared over 1, 6, and 12 months. Outcomes in patients with a retroverted or large uterus size, defect size, and local vascularization also were evaluated. RESULTS: At 12 months post-treatment, there were no significant differences between groups in efficacy rate; however, the reduction of intermenstrual bleeding days was higher in the LNG-IUD group than in the resectoscopy group (13.6 vs. 8.5 days, p = 0.015). Within the first year, both groups experienced a reduction in bleeding days, but the decrease was greater in the LNG-IUD group. Individuals exhibiting increased local vascularization at the defect site experienced more favorable outcomes in the LNG-IUD group than the resectoscopy group (p = 0.016), and who responded poorly tended to have a significantly larger uterus in the LNG-IUD group (p = 0.019). No significant differences were observed in treatment outcomes for patients with a retroverted uterus or large defect in either group. CONCLUSIONS: Our findings support that the LNG-IUD is as effective as resectoscopy in reducing intermenstrual bleeding days associated with PCDS and can be safely applied to patients without recent fertility aspirations. Patients with increased local vascularization observed during hysteroscopy may benefit more from LNG-IUD intervention than resectoscopy.

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: The purpose of this study is to compare the effects of cyclic oral dydrogesterone treatment and levonorgestrel-releasing intrauterine device (LNG_IUD) on quality of life (QoL) and sexual function in patients diagnosed with abnormal uterine bleeding (AUB). STUDY DESIGN: The study was conducted at the University of Health Sciences Turkey Health Istanbul Kanuni Sultan Süleyman Training and Research Hospital, on 171 sexually active patients, aged 18-45, who were under a minimum of 6 months of treatment for AUB. 85 patients were treated with oral cyclic dydrogesterone, and 86 patients received LNG-IUD. Following a minimum of 6 months of treatment, these patients were recruited to the study and were asked to complete a 36-Item Short Form Survey (SF-36) and the Female Sexual Function Index (FSFI). RESULTS: When the FSFI scores of the patients were compared, it was observed that the total FSFI score was significantly higher in the cyclic dydrogesterone group (p < 0.05). Likewise, it was observed that sexual desire, arousal, and lubrication domains were significantly higher in the cyclic dydrogesterone group (p < 0.05). No significant differences were found between the treatment groups in 7 out of the 8 dimensions of SF-36. The energy/vitality dimension was found to be significantly higher in the cyclic dydrogesterone group. CONCLUSION: Total FSFI score, as well as sexual desire, arousal, and lubrication scores, were significantly higher in the cyclic dydrogesterone group compared to the LNG-IUD group indicating that cyclic dydrogesterone has a more positive impact on sexual function when compared to LNG-IUD.

RESUMO

PURPOSE: Short-acting progestin-only injectables containing depot medroxyprogesterone acetate (DMPA) are a safe method of contraception. Although DMPA has been available for several decades, there is little data on its influence on the risk of breast cancer. Hence, the aim of this paper was to provide an overview of the existing studies and create clarity regarding a possible association with breast cancer. METHODS: Literature searches were executed in MEDLINE, Embase, the Cochrane Library, ClinicalTrials.gov and ICTRP. Search terms were related to DMPA and breast cancer. After elimination of duplicates, 3'850 studies were identified and assessed according to inclusion and exclusion criteria. Finally, ten studies were selected and included in this review. RESULTS: All the selected papers were case-control-studies, except for one pooled analysis and one study comparing observed and expected number of cancer cases. Most of the included studies found no overall elevated breast cancer incidence in DMPA users, only one study found a slightly increased risk and two studies concluded with a significant increase for the overall breast cancer risk. CONCLUSION: There is little evidence that DMPA may increase the overall risk for breast cancer. However, the incidence of breast cancer is possibly increased in current and more recent users, especially in women younger than 35 years. Long-term use did not result in any risk increase. Nevertheless, further studies will be necessary to confirm these findings and weigh up the individual risks and benefits of this contraceptive method.

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

Depot medroxyprogesterone acetate causes a hypo-estrogenic state in over half of users although clinical vaginal atrophy causing superficial dyspareunia is thought rarely to occur. This is a case series of ten women using depot medroxyprogesterone acetate who presented with superficial dyspareunia and clinical vaginal atrophy. The women were treated with vaginal estriol cream and their contraception was discontinued or changed. All patients had either a complete resolution of symptoms or a substantial improvement at follow-up, and the clinical and laboratory findings of vaginal atrophy had resolved. This case series demonstrates that vaginal atrophy may occur more frequently than previously thought.

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

PURPOSE: To evaluate the impact of levonorgestrel-releasing intrauterine device (LNG-IUD) use on the incidence of acne in adolescents and young women. METHODS: A narrative review was conducted in PubMed, Embase, Cochrane, and SciELO assessing the incidence of acne in adolescents and young women using LNG-IUD (13.5, or 19.5 mg, or 52 mg). Cohort, cross-sectional studies, clinical trials, and meta-analyses were included, without a date limit. Studies that didn't evaluate women in the age of interest were excluded. Only articles in English were selected. RESULTS: Nine articles were included in this narrative review. Only clinical trials, cohort studies, and cross-sectional studies were evaluated. Two cross-sectional studies evaluated the incidence of acne in women using any contraceptive methods, with the incidence of acne being 36% in women aged 17 to 47 using LNG-IUD in one study. In another study, acne incidence ranged from 2 to 8% in women using any contraceptive methods, with higher rates in younger women and LNG-IUD users. The incidence of acne varies and participants between 16 to 35 years were more likely to report new acne or worsening of pre-existing acne. In a prospective cohort study of women between 16 and 24 years, acne was a common adverse effect, with 44% in the first year. CONCLUSION: The data indicate variability in the incidence of acne among LNG-IUD users, with a higher prevalence observed in younger women. Further research should focus on the effects of LNG-IUD on acne in young populations, with rigorous study designs and consideration of previous contraceptive use.


The levonorgestrel-releasing intrauterine device (LNG-IUD) is an important tool in the prevention of unplanned pregnancies in adolescents and young women. Acne is a possible adverse effect that could lead to discontinuation of the method.
