The suture fixation of the levonorgestrel-releasing intrauterine device with hysteroscope for the treatment of adenomyosis in patients at high risk of device expulsion-a prospective observational study

BackgroundThis study aimed to investigate the safety and efficacy of suture fixation of the levonorgestrel-releasing intrauterine device (LNG-IUD) by hysteroscope for the treatment of adenomyosis in patients at high risk of device expulsion, to provide a viable treatment option for these patients.MethodsTwenty-one patients with large symptomatic adenomyosis were sewed and fixed with the LNG-IUD in the uterus by hysteroscopy to prevent the device expulsion.ResultsIn this prospective case series, all 21 patients were successfully sewed and fixed with the LNG-IUD in the uterus by hysteroscopy. The amount of menstruation was significantly decreased and dysmenorrhea was significantly relieved in 3, 6, and 12 months after surgery compared with before surgery. Only one patient underwent a laparoscopic hysterectomy due to dysmenorrhea which was not alleviated one month later. Serious IUD complications including expulsion and perforation were not observed. There was no development of new side effects than LNG-IUD insertion.ConclusionOur findings indicate that suture fixation of the LNG-IUD by hysteroscope is a safe, effective, and minimally invasive surgical procedure to prevent the device expulsion. It is a good solution for the treatment of large symptomatic adenomyosis and has shown to be effective in managing symptoms related to adenomyosis.

Frequent Use of Premenopausal Progestin in Prior Pre-Eclamptic Women.

Women with a history of pre-eclamptic pregnancy are predisposed to later occlusive vascular diseases. We compared the use of cyclic progestins or levonorgestrel-releasing intrauterine device (LNG-IUD) for treatment of menstrual cycle abnormalities between premenopausal women with and without a prior pre-eclamptic pregnancy. Register-based cohort study during 1994-2019 of oral progestin or levonorgestrel-releasing intrauterine device (LNG-IUD) in Finnish women with (n=31 688) and without (n=91 726) prior pre-eclampsia in 1969-1993. Cyclic progestin or LNG-IUD use and its association with future use of menopausal hormone therapy (MHT). Prior pre-eclamptic women had used cyclic progestins more often (23.5% vs. 9.1%; p<0.001) and initiated the use at younger ages (41.8 years [SD=6.3] vs. 45.9 years [3.1]; p<0.001) than control women. Also, LNG-IUD was inserted more frequently (p<0.001) in prior pre-eclamptic women (9.3%) than in controls (4.7%). Cyclic progestin or LNG-IUD use was accompanied by significant 37-90% elevations in future MHT use. Increased use of cyclic progestins and LNG-IUD in premenopausal women with a history of pre-eclamptic pregnancy can be seen as indirect evidence of earlier onset of ovulatory dysfunction. This may contribute to the elevated risk of endometrial cancer in these women. Our findings may indicate one additional late sequela of pre-eclamptic pregnancy.

Continuation of the levonorgestrel-releasing intrauterine device among adolescents with endometriosis

Study ObjectiveTo estimate the 1-year continuation rate of the levonorgestrel-releasing intrauterine device (LNG-IUD) in adolescents with endometriosis, and the frequency at which additional systemic hormonal treatment (HT) is utilized. MethodsA retrospective cohort study was performed of patients aged 12 – 21 years who underwent laparoscopy for endometriosis and LNG-IUD insertion at a single tertiary care institution between 2018 and 2021. ResultsWe evaluated 224 adolescents (mean age=17.0, SD=1.8 years) who underwent LNG-IUD placement during laparoscopic evaluation for endometriosis. Stage I endometriosis was most common (84.4%), followed by stage II (13.0%). Of 221 with follow-up, 208 (94.1%) had HT added or continued post-surgery. The most common additional HT was norethindrone acetate (42.5%), followed by combined hormonal contraceptives (34.8%). The 1-year LNG-IUD continuation rate was 92.0%. There were 18 IUD removals (8%) by 1 year, and the median time to removal was 118 days (IQR=159; range 8-293). Use of additional HT was associated with a lower hazard of IUD removal within the first year of use (HR = 0.19, 95% CI: 0.06-0.56, p<0.001). ConclusionThe majority of adolescents used the LNG-IUD with additional systemic HT for endometriosis management. While overall continuation was high, adolescents who were using LNG-IUD and HT were more likely to continue LNG-IUD than those who were not utilizing additional HT.

Risk of Stroke in Women Using Levonorgestrel-Releasing Intrauterine Device for Contraception.

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. 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. 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). 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.

Leiomyomatosis: A Rare Case of Mistaken Identity

Abstract: Diffuse uterine leiomyomatosis (DUL) is a rare benign uterine pathology that is often misdiagnosed as uterine leiomyomas. We present a case of a woman with abnormal uterine bleeding treated with multiple medical therapies without symptomatic relief. She underwent two surgeries, almost a year apart, with the histopathologic diagnosis of leiomyomas. After numerous failed attempts at medical and surgical treatments, the patient requested definitive surgery and underwent a robotic-assisted laparoscopic hysterectomy. Histopathologic analysis of the entire uterine specimen confirmed diffuse uterine leiomyomatosis. Case Report: A 31-year-old female was referred to our office with a history of abnormal uterine bleeding and heavy menstrual bleeding who failed hormonal therapies. Levonorgestrel-releasing intrauterine devices were inserted at two different times and were expelled due to heavy menses. Pelvic magnetic resonance imaging reported leiomyomas. The patient underwent hysteroscopy and a robotic-assisted myomectomy. Pathology revealed leiomyomas. Seven months after her first surgery, her bleeding recurred, and the patient became severely anemic, requiring hospitalization and transfusion of 2 units of packed RBCs. Over a year later, the patient underwent a second hysteroscopic and robotic myomectomy after failed medical therapies of tranexamic acid, progesterone medication, and gonadotropin-releasing hormone antagonist with minimal symptom relief. Her quality of life suffered tremendously due to ongoing AUB-HMB. After seven months, the patient requested definitive surgical therapy and underwent a robotic-assisted laparoscopic hysterectomy. Pathology reported diffuse uterine leiomyomatosis. Diffuse uterine leiomyomatosis is a rare benign uterine pathology that is often misdiagnosed as uterine leiomyomas. Early diagnosis of DUL is challenging and often inconclusive. Less than 50 diffuse uterine leiomyomatosis cases have been reported in the literature. The myometrium in DUL is almost entirely replaced by numerous ill-defined benign smooth muscle tumors. MRI offers mapping of the size, site, and distribution of leiomyomas, but findings are difficult to differentiate from DUL. The pathophysiology of DUL development remains poorly understood, with patients frequently complaining of abnormal uterine bleeding, heavy menstrual bleeding, fertility issues, and dysmenorrhea. DUL is often misdiagnosed as leiomyomas or adenomyosis clinically, given the similarity in manifestations. Leiomyomatosis is histologically characterized by the proliferation of smooth muscle cells forming fascicles and nodules, which blend with normal myometrium tissue. Hysterectomy is the definitive treatment of DUL, with this case report demonstrating the close similarity between the two.

Menstrual blood loss is an independent determinant of hemoglobin and ferritin levels in premenopausal blood donors.

To prevent blood donors from developing iron deficiency (ferritin <15 μg/L) and subsequent anemia (hemoglobin <120 g/L), blood services rely on information about known risk factors, including the donor's sex and age. For example, while Finnish women are able to donate whole blood with a minimum donation interval of 91 days, women in the 18 to 25-year-old age group are recommended to donate no more than once per year. Menstrual blood loss is not accounted for in blood donation interval recommendations, despite being a known risk factor of iron deficiency. We aim to investigate to what extent menstrual bleeding is associated with ferritin and hemoglobin levels in female blood donors, and quantify the association of other menstruation-related variables not currently accounted for by blood services (i.e., use of hormonal contraception, heavy menstrual bleeding) with iron deficiency or anemia. The study population consisted of 473 premenopausal and 491 postmenopausal Dutch whole blood donors. Exclusion criteria were current pregnancy, BMI ≥50, ferritin ≥200, pictorial blood assessment chart (PBAC) ≥400, and age <18 or ≥70 years. Menstrual blood loss was quantified using a PBAC, a semiquantitative method to evaluate the number of used menstrual products and the degree of staining. We identified predictors of log(ferritin)/hemoglobin and iron deficiency/anemia using Bayesian linear and logistic regression models and quantified the average percentage of variance in log(ferritin) and hemoglobin explained by the covariates. Menstrual blood loss accounted for most of the explained variance in hemoglobin (8%) and second only to the number of days since last donation for ferritin (8%). Heavy menstrual bleeding (PBAC ≥150, OR = 3.56 [1.45-8.85], prevalence 13%) was associated with anemia, and use of levonorgestrel-releasing intrauterine device was negatively associated with iron deficiency (OR = 0.06 [0.01-0.44]). After statistical control for menstrual blood loss, age was not associated with iron status. Menstrual blood loss and blood donation were the most important determinants of iron status in premenopausal women. Thus, results suggest that accounting for menstrual blood loss in donation interval guidelines may benefit blood donors.

Efficacy of hysteroscopic levonorgestrel‑releasing intrauterine device fixation in the treatment of adenomyosis: A cohort study.

The present study aimed to investigate the efficacy of hysteroscopic levonorgestrel-releasing intrauterine device (LNG-IUD) fixation surgery in the treatment of adenomyosis through a cohort study. The cohort study was performed at the Affiliated Jinhua Hospital of Wenzhou Medical University (Jinhua, China). A total of 31 women with adenomyosis were initially recruited from June 2020 to June 2022 and divided into an experimental group and a control group. The experimental group underwent hysteroscopic LNG-IUD fixation surgery and the control group underwent conventional implantation of the levonorgestrel-releasing intrauterine system. The assessed efficacy outcomes included the time of LNG-IUD expulsion, postoperative vaginal bleeding time, dysmenorrhea, and the menstrual blood loss score (MBLS). A total of 31 participants completed the research. The LNG-IUD expulsion rate was 6.25 and 60% (P<0.05) in the experimental and control group, respectively. The LNG-IUD in place time was 20.50 months (Q1, 15.75; Q3, 24.00) in the experimental group and 10.00 months (Q1, 6.50; Q3, 15.00) in the control group (P<0.05); the time of vaginal bleeding after surgery in the experimental and control groups were 12.50 days (9.25, 16.25) and 120.00 days (75.00, 120.00), respectively (P<0.05). Multiple-factor Cox regression analysis revealed that the LNG-IUD expulsion in patients with adenomyosis is associated with the hysteroscopic LNG-IUD fixation surgery [hazard ratio (HR), 1954.09], uterine cavity depth (HR, 16.63), MBLS (HR, 1.14), history of gonadotropin-releasing hormone agonist treatment in the previous 6 months (HR, 2.10), history of vaginal delivery (HR, 1.79) and history of cervical laceration (HR, 3.69). In conclusion, hysteroscopic LNG-IUD fixation reduces the rate of LNG-IUD expulsion, prolongs the time of LNG-IUD in the uterine cavity, reduces the time of postoperative vaginal bleeding, relieves the symptoms of dysmenorrhea and reduces the menstrual volume in the patients with adenomyosis. The present trial was retrospectively registered in the Chinese Clinical Trial Registry on 28th December 2023 (registration no. ChiCTR2300079233).

Comparative analysis of endometrium after using levonorgestrel-releasing intrauterine system and copper intrauterine device

BACKGROUND: To date, the risks of pelvic inflammatory diseases, including chronic endometritis, associated with the use of various intrauterine contraceptives, have remained debatable. AIM: The aim of this study was to conduct a comparative analysis of the endometrial status in women of reproductive age after the use of copper- or levonorgestrel-releasing intrauterine device. MATERIALS AND METHODS: Morphological and immunohistochemical studies of endometrial biopsies obtained by aspiration Pipelle biopsy were performed after intrauterine device extraction in 18 patients who used a copper-containing intrauterine device and in 12 women who used the levonorgestrel-releasing intrauterine device Mirena. Monoclonal mouse antibodies to CD20, CD138, and α-smooth muscle actin (DAKO, Denmark) were used. Criteria for inclusion of patients in the study are reproductive age, use of an intrauterine device for five years, absence of complications associated with the intrauterine device during its use. Exclusion criteria are a history of pelvic inflammatory diseases, sexually transmitted infections, habitual miscarriage, two or more intrauterine interventions. RESULTS: After using a copper-containing intrauterine device, signs of chronic inflammation were found in the endometrium such as cytogenic stroma fibrosis with pronounced infiltration by inflammatory cells, positive expression of CD138 (33.3% of observations), CD20 (88.9% of observations with an average number of 27.4 ± 5.7), α-smooth muscle actin (up to 70% of the cytogenic stroma area), and the presence of lymphatic follicles consisting of B lymphocytes (33.3% of observations). During the use of the levonorgestrel-releasing intrauterine device, decidual transformation of cytogenic stroma cells, as well as secretion and atrophy of the glandular epithelium, were found in the endometrium. CD20-positive cells were detected in five out of 12 cases (41.6% of observations with an average number of 12.8 ± 4.6). Expression of CD138 and α-smooth muscle actin was not detected in any of the cases. CONCLUSIONS: The use of a copper-containing intrauterine device is associated with a high risk of developing chronic endometritis. The absence of signs of chronic inflammation in the endometrium after the use of a levonorgestrel-releasing intrauterine device is probably due to the protective effect of levonorgestrel on the uterine mucosa. Thus, levonorgestrel-releasing intrauterine devices, in comparison with copper-containing intrauterine devices, have a favorable safety profile relative to the endometrium and can be recommended for women of reproductive age, including those who have not given birth.

Association of levonorgestrel-releasing intrauterine device with gynecologic and breast cancers: a national cohort study in Sweden

BackgroundThe 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. ObjectiveWe 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 DesignA total of 514719 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 1544157 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 and 95% confidence intervals. 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. ResultsThe 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 < 0.002), and 1.63 additional cases per 10,000 person-years. ConclusionsThe risk of gynecologic and breast cancers exhibits a site-specific effect among LNG-IUD users. It's 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.

Moderate associations between the use of levonorgestrel-releasing intrauterine device and metabolomics profile.

Use of levonorgestrel-releasing intrauterine device (LNG-IUD) has become common irrespective of age and parity. To date, only a few studies have examined its possible metabolic changes and large-scale biomarker profiles in detail and in a longitudinal design. To apply the metabolomics technique to examine the metabolic profile associated with the use of LNG-IUD both in a cross-sectional and in a longitudinal design. The study consists of cross-sectional and longitudinal analyses of a population-based survey (Health 2000) and its 11-year follow-up (Health 2011). All participants aged 18-49 years with available information on hormonal contraceptive use and metabolomics data (n=1767) were included. Altogether 212 metabolic measures in LNG-IUD users (n=341) were compared to those in non-users of hormonal contraception (n=1426) via multivariable linear regression models. Participants with complete longitudinal information (n=240) were divided into continuers, stoppers, starters, and never-user groups, and 11-year changes in levels of each metabolite were compared. After adjustment for covariates, levels of 102 metabolites differed in LNG-IUD current users compared to non-users of hormonal contraception (median difference in biomarker concentration: -0.12 SD): lower levels of fatty acids concentrations and ratios, cholesterol, triglycerides and other lipids, as well as particle concentration, cholesterol, total lipids and phospholipids in lipoproteins. The 11-year metabolic changes did not differ in relation to changes in LNG-IUD use. The use of LNG-IUD was associated with several moderate metabolic changes, mostly suggestive of a reduced arterial cardiometabolic risk. Changes in LNG-IUD use were not related to long-term metabolic changes.

Hormonal contraceptive use after a first venous thrombotic event and the risk of recurrence in premenopausal women

BackgroundExtensive 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. ObjectivesWe aimed to evaluate the VTE recurrence risk associated with HC use in premenopausal women. MethodsPremenopausal 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. ResultsSix 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). ConclusionCHC 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.

Treatment outcomes according to various progestin treatment strategies in patients with atypical hyperplasia/endometrial intraepithelial neoplasia – Multicenter retrospective study (KGOG2033)

ObjectiveTo investigate pathologic complete response (pCR) and recurrence outcomes using various progestin treatment strategies in patients with atypical hyperplasia/endometrial intraepithelial neoplasia (AH/EIN). MethodsMedical records of patients diagnosed with AH/EIN and undergoing follow-up endometrial biopsy after progestin treatment between 2011 and 2020 were retrospectively reviewed. Clinical factors and treatment outcomes were analyzed according to initial progestin treatment (oral progestin [OP], levonorgestrel-releasing intrauterine device [LNG-IUD], and combination), OP dose, and maintenance treatment using Pearson's χ2, Fisher's exact test, and Kaplan-Meier analysis. ResultsOf 124 patients included, 74, 37, and 13 were in the OP, LNG-IUD, and combination groups, respectively. The pCR rate was 79.8% and recurrence rate was 21.2%. The pCR rates within 3 and 6 months were significantly higher in the OP group than in the LNG-IUD group, but were not significantly different within 12 and 24 months. Recurrence rate was significantly higher in the OP group than in the LNG-IUD group. The pCR rate and recurrence rate had no significant differences between the combination group and the other groups. Excluding the LNG-IUD group, 53 and 34 patients received low- and high-dose OP, respectively. The pCR and recurrence rates were comparable between the low- and high-dose OP groups. Maintenance therapy was significantly associated with lower recurrence rate. ConclusionsAlthough OP alone achieved more short-term pCR than the other groups, more recurrences occurred after pCR than LNG-IUD alone. High-dose OP as well as combination of OP and LNG-IUD did not increase pCR or reduce recurrence. Maintenance therapy may reduce the recurrence rate after pCR.

A 52-mg levonorgestrel-releasing intrauterine system vs bipolar radiofrequency nonresectoscopic endometrial ablation in women with heavy menstrual bleeding: long-term follow-up of a multicenter randomized controlled trial

BACKGROUNDThe symptom of heavy menstrual bleeding has a significant impact on professional, physical and social functioning. In 2021, results from a randomized controlled trial comparing a 52 mg levonorgestrel-releasing intrauterine system and radiofrequency non-resectoscopic endometrial ablation as treatments for women with heavy menstrual bleeding were published. Both treatment strategies were equally effective in treating heavy menstrual bleeding during a two-year follow-up. However, long-term results are also relevant for both patients and health care providers. OBJECTIVEThe aim of this study was to assess long-term differences in reintervention risk and menstrual blood loss in women with the symptom of heavy menstrual bleeding treated according to a strategy starting with a 52 mg levonorgestrel-releasing intrauterine system or radiofrequency non-resectoscopic endometrial ablation. STUDY DESIGNThis study was a long-term follow-up study of a multi-center randomized controlled trial (MIRA trial) in which women were allocated to either a 52 mg levonorgestrel-releasing intrauterine device (n=132) or radiofrequency non-resectoscopic endometrial ablation (n=138). Women from the original trial were contacted to fill out six questionnaires. The primary outcome was reintervention rate after allocated treatment. Secondary outcomes included surgical reintervention rate, menstrual bleeding measured by the Pictorial Blood Loss Assessment Chart, (disease-specific) quality of life, sexual function and patient satisfaction. RESULTSFrom the 270 women that were randomized in the original trial, 196 women (52 mg levonorgestrel-releasing intrauterine system group: n=94; radiofrequency non-resectoscopic endometrial ablation group: n=102) participated in this long-term follow-up study. Mean follow-up duration was 7.4 years (range 6-9 years). The cumulative reintervention rate (including both medical and surgical reinterventions) was 40.0% (34/85) in the 52 mg levonorgestrel-releasing intrauterine system group and 28.7% (27/94) in the radiofrequency non-resectoscopic endometrial ablation group (relative risk: 1.39; 95% confidence interval: 0.92-2.10). The cumulative rate of surgical reinterventions only was significantly higher for patients with a treatment strategy starting with a 52 mg levonorgestrel-releasing intrauterine system compared to radiofrequency non-resectoscopic endometrial ablation (35.3% [30/85] vs. 19.1% [18/94]; relative risk: 1.84; 95% confidence interval: 1.11-3.10). However, hysterectomy rate was similar: 11.8% [10/94] in the 52 mg levonorgestrel-releasing intrauterine system group and 18.1% [17/102] in the radiofrequency non-resectoscopic endometrial ablation group (relative risk: 0.65; 95% confidence interval: 0.32-1.34). Most reinterventions took place during the first 24 months of follow-up. A total of 171 Pictorial Blood Loss Assessment Chart scores showed a median bleeding score of 0.0. No clinically relevant differences were found regarding quality of life, sexual function and patient satisfaction. CONCLUSIONThe overall risk of reintervention after long-term follow-up was not different for women treated according to a treatment strategy starting with a 52 mg levonorgestrel-releasing intrauterine system as compared to a strategy starting with radiofrequency non-resectoscopic endometrial ablation. Yet, women allocated to a treatment strategy starting with a 52 mg levonorgestrel-releasing intrauterine system had a significantly higher risk for surgical reintervention, which was driven by an increase in subsequent endometrial ablation. Both treatment strategies remain effective in lowering menstrual blood loss over the long-term. The results of this long-term follow-up study help physicians to optimize counseling of women suffering from the symptom of heavy menstrual bleeding. Optimized counseling will enable women to make a well-informed choice regarding treatment.

The levonorgestrel-releasing intrauterine device is related to early emotional reactivity: An ERP study

Despite the evidence of altered emotion processing in oral contraceptive (OC) users, the impact of hormonal intrauterine devices (IUD) on emotional processing remains unexplored. Our study aimed to investigate how behavioural performance and event-related potentials (ERPs) linked with emotion reactivity and its regulation are associated with hormonal profiles of women using different types of hormonal contraception and naturally cycling women. Women using OCs (n = 25), hormonal IUDs (n = 33), and naturally cycling women in their early follicular (NCF, n = 33) or mid-luteal (NCL, n = 28) phase of the menstrual cycle were instructed to view emotional pictures (neutral, low and high negativity) and use cognitive reappraisal to up- or down-regulate negative emotions, while their electroencephalogram was recorded. Participants rated perceived negativity after each picture and their emotional arousal throughout the task. Saliva samples were collected to assess levels of 17β-estradiol, progesterone, and testosterone. As expected, emotional arousal increased throughout the task and correlated positively with perceived negativity. Perceived negativity and the amplitudes of the middle (N2/P3) and later (LPP) latency ERP components increased with increasing stimuli negativity. Emotion regulation modulated perceived negativity and the amplitudes of very late ERP components (parietal and frontal LPP). Moreover, IUD-users showed a higher negative amplitude of the frontal N2 in comparison to all three other groups, with the most consistent differences during up-regulation. Finally, testosterone correlated positively with the N2 peak in IUD-users and NCL women. Overall, our findings suggest that IUD-use and testosterone might be related to altered preconscious processing during the emotion regulation task requiring attention to the stimulus. The study underscores the need for additional research into how different hormonal contraceptives are linked to socio-emotional functioning.

Laparoscopic adenomyomectomy combined with levonorgestrel-releasing intrauterine system is effective for long-term management of adenomyosis

BackgroudLaparoscopic adenomyomectomy combined with intraoperative placement of levonorgestrel-releasing intrauterine device (LNG-IUS) is a novel conservative surgical procedure for adenomyosis. Our study aimed to compare the efficacy of surgery with or without intraoperative placement of LNG-IUS treatment in adenomyosis.MethodsWe retrospectively reviewed the medical records of adenomyosis patients who received laparoscopic adenomyomectomy from January 2014 to April 2020, finally including 70 patients undergoing surgery-LNG-IUS as group A and 69 patients undegoing surgery only as group B. Risk factors for three-year relapse were analyzed using Cox’s multivariate proportional hazard analysis.ResultsVisual analog scale and Mansfield-Voda-Jorgensen Menstrual Bleeding Scale scores of group A at 3, 6, 12, 24, and 36 months were significantly lower than those of group B at the corresponding points (P < .001 for both scales). Individuals in both groups showed statistically significant symptom relief. The recurrence rate in group A was significantly lower than that in group B at 36 months after the surgery (2.94% vs. 32.84%, P < .001). A cox proportional hazard model showed that relapse was significantly associated with coexisting ovarian endometriosis (adjusted hazard ratio [aHR], 2.94; 95% confidence interval [CI], 1.33–7.02, P = .015). Patients who received surgery-LNG-IUS had a lower risk of recurrence than those with surgery-alone (aHR, 0.07; 95% CI, 0.016–0.31, P < .001).ConclusionsConservative surgery with intraoperative placement of LNG-IUS is effective and well-accepted for long-term therapy with a lower recurrence rate for adenomyosis. Coexistent ovarian endometriosis is a major factor for adenomyosis relapse.

Efficacy of misoprostol in reducing the time and easiness the insertion of Levonorgestrel-releasing intrauterine device; Randomized controlled trial

Background: intrauterine devices (IUDs) have gained significant popularity as a prevalent form of reversible contraception. Levonorgestrel-releasing intrauterine devices (LNG-IUDs) have been found to be safe and cost-effective over an extended period. Furthermore, their efficacy is comparable to that of tubal sterilization. Aim: The aim of our study to reveled the effect of vaginal misoprostol on timing and the easiness of insertion of (LNG-IUDs) in previous cesarean sections women. Materials and method: One-hundred and eighty patients with a previous cesarean section attending for Mirena LNG-IUD insertion. This Randomized controlled trial set in Outpatient clinic in Department of Obstetrics and Gynecology, Faculty of Medicine, Helwan University Hospital at BADR city from March 2021 to March 2022. The current research assessed the effectiveness of 400mcg vaginal misoprostol 6 hours before LNG-IUD insertion in women who had only had a cesarean section before. Results: one hundred- eighty patients included in our Randomized control trial. Our results; There was statistically insignificant terms of anticipated pain, Pain after 20 min and satisfaction p-value&gt;0.05.While, we found a statistically significant difference in Ease of insertion, Pain at insertion and Insertion time &lt;0.001. Moreover, there was no statistically significant nausea, vomiting, shivering, fever, and need additional analgesia p-value&gt;0.05. Conclusion: misoprostol is safe and effective in insertion the LNG-IUD because of the significant result in reduction of pain, timing and easiness of insertion.

A comparison of the effects of oral dydrogesterone and levonorgestrel-releasing intrauterine device on quality of life and sexual function in patients with abnormal uterine bleeding.

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). 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 6months 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). 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. 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.

Levonorgestrel-releasing intrauterine device to treat abnormal uterine bleeding; not one treatment option fits all.

Initially, medical treatment options are preferred in patients with abnormal uterine bleeding (AUB) who are hemodynamically stable. The aim of the present study was to investigate the effectiveness of a levonorgestrel-releasing intrauterine device (LNG-IUD) in reducing bleeding symptoms in patients with AUB stratified by underlying pathology. In line with the polyp, adenomyosis, leiomyoma, malignancy (and hyperplasia), coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified classification system, patients who were administered LNG-IUD due to adenomyosis, endometrial hyperplasia, leiomyoma and AUB due to not otherwise classified causes were included in the study. A total of 172 otherwise patients with a mean age of 42.58±5.00 years were included. The distributions in the adenomyosis, endometrial hyperplasia, leiomyoma and otherwise unclassified groups were 30.8%, 12.8%, 26.2%, and 30.2%, respectively. Overall effectiveness of LNG-IUD in reducing menstrual bleeding was 82%. The proportion whose bleeding decreased was 95.50% in the endometrial hyperplasia group, 88.70% in the adenomyosis group, 55.60% in the leiomyoma group and 92.30% in the not otherwise classified group. The power of the current study was 99%. The efficacy of LNG-IUD was significantly less in the leiomyoma group (p<0.05) and thus this group were more likely to require surgical intervention. The overall incidence of spotting was 50%. Amenorrhea developed in 14% of patients. While LNG-IUD was more effective in reducing symptoms of AUB in patients with adenomyosis, endometrial hyperplasia and not otherwise classified causes, LNG-IUD was less effective in cases of leiomyoma.

Proposal for targeted, neo-evolutionary-oriented secondary prevention of early-onset endometriosis and adenomyosis. Part II: medical interventions.

According to consistent epidemiological data, the slope of the incidence curve of endometriosis rises rapidly and sharply around the age of 25 years. The delay in diagnosis is generally reported to be between 5 and 8 years in adult women, but it appears to be over 10 years in adolescents. If this is true, the actual onset of endometriosis in many young women would be chronologically placed in the early postmenarchal years. Ovulation and menstruation are inflammatory events that, when occurring repeatedly for years, may theoretically favour the early development of endometriosis and adenomyosis. Moreover, repeated acute dysmenorrhoea episodes after menarche may not only be an indicator of ensuing endometriosis or adenomyosis, but may also promote the transition from acute to chronic pelvic pain through central sensitization mechanisms, as well as the onset of chronic overlapping pain conditions. Therefore, secondary prevention aimed at reducing suffering, limiting lesion progression, and preserving future reproductive potential should be focused on the age group that could benefit most from the intervention, i.e. severely symptomatic adolescents. Early-onset endometriosis and adenomyosis should be promptly suspected even when physical and ultrasound findings are negative, and long-term ovulatory suppression may be established until conception seeking. As nowadays this could mean using hormonal therapies for several years, drug safety evaluation is crucial. In adolescents without recognized major contraindications to oestrogens, the use of very low-dose combined oral contraceptives is associated with a marginal increase in the individual absolute risk of thromboembolic events. Oral contraceptives containing oestradiol instead of ethinyl oestradiol may further limit such risk. Oral, subcutaneous, and intramuscular progestogens do not increase the thromboembolic risk, but may interfere with attainment of peak bone mass in young women. Levonorgestrel-releasing intra-uterine devices may be a safe alternative for adolescents, as amenorrhoea is frequently induced without suppression of the ovarian activity. With regard to oncological risk, the net effect of long-term oestrogen-progestogen combinations use is a small reduction in overall cancer risk. Whether surgery should be considered the first-line approach in young women with chronic pelvic pain symptoms seems questionable. Especially when large endometriomas or infiltrating lesions are not detected at pelvic imaging, laparoscopy should be reserved to adolescents who refuse hormonal treatments or in whom first-line medications are not effective, not tolerated, or contraindicated. Diagnostic and therapeutic algorithms, including self-reported outcome measures, for young individuals with a clinical suspicion of early-onset endometriosis or adenomyosis are proposed.
