Data on record regarding weight variation in depot-medroxyprogesterone acetate (DMPA) and levonorgestrel-releasing intrauterine system (LNG-IUS) users are controversial. To date, no studies have yet evaluated weight variation in DMPA and LNG-IUS users in up to ten years of use compared to non-hormonal contraceptive users. A retrospective study analysed weight variations in 2138 women using uninterruptedly DMPA (150 mg intramuscularly, three-monthly; n = 714), the LNG-IUS (n = 701) or a copper-intrauterine device (Cu-IUD; n = 723). At the end of the first year of use, there was a mean weight increase of 1.3 kg, 0.7 kg and 0.2 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively, compared to weight at baseline (p < 0.0001). After ten years of use, the mean weight had risen by 6.6 kg, 4.0 and 4.9 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively. DMPA-users had gained more weight than LNG-IUS- (p = 0.0197) and than Cu-IUD users (p = 0.0294), with the latter two groups not differing significantly from each other in this respect (p = 0.5532). Users of hormonal and non-hormonal contraceptive methods gained a significant amount of weight over the years. DMPA users gained more weight over the treatment period of up to ten years than women fitted with either a LNG-IUS or a Cu-IUD.

Background: The study was conducted to evaluate the cardiovascular risk markers associated with endometriosis and the influence of the levonorgestrel intrauterine system (LNG-TUS) compared with the GnRH analogue (GnRHa) leuprolide acetate on these risk markers after 6 months of treatment. Study Design: This was a randomized, prospective, open clinical Study, with 44 patients with laparoscopically and histologically confirmed endometriosis. Patients were randomized into two groups: the LNG-IUS group, composed of 22 patients who underwent LNG-IUS insertion., and the GnRHa group, composed of 22 patients who received a monthly GnRHa injection for 6 months. Body mass index systolic and diastolic arterial blood pressure; heart rate; and laboratory cardiovascular risk markers such as interlelikin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP), homocysteine (HMC), lipid profile, total leukocytes and vascular cell adhesion molecule (VCAM) were measured before and 6 months after treatment. Results: After 6 months of treatment, a significant reduction in pain score occurred in both groups with no significant difference in improvement between the two medications evaluated. In the LNG-IUS group, from pretreatment to posttreatment period, there was a significant reduction in the levels (mean +/- SD) of VCAM (92.8 +/- 4.2 to 91.2 +/- 2.7 ng/mL, p=.04), CRP (0.38 +/- 0.30 to 0.28 +/- 0.21 mg/dL, p=.03), total cholesterol (247.0 +/- 85.0 to 180.0 +/- 31.0 mg/dL, p=.0002), triglycerides (118.0 +/- 76.0 to 86.5 +/- 41.5 mg/dL, p=.003), low-density lipoprotein cholesterol (160.5 +/- 66.0 to 114.5 +/- 25.5 mg/dL, p=.0005) and high-density lipoprotein cholesterol (63.0 +/- 20.5 to 48.5 +/- 10.5 mg/dL, p=.002). The GnRHa group showed an increase in HMC levels (11.5 +/- 2.9 to 13.0 +/- 2.7 mu mol/L, p=.04) and a reduction in IL-6 levels (4.3 +/- 3.9 to 2.3 +/- 0.8 pg/mL, p=.005), VCAM (94.0 +/- 3.8 to 92.0 +/- 1.6 ng/mL, p=.03) and total leukocytes (7330 +/- 2554 to 6350 +/- 1778, p=.01). In the GnRH group, the remaining variables, including lipid profile, did not show any statistical difference. Conclusions: This study shows that some cardiovascular risk markers are influenced by both GnRHa and the LNG-TUS, but the latter had a greater positive impact on the lipid profile, which could lead to a favorable effect during long-term treatment.

We compared the effects of levonorgestrel-releasing intrauterine devices (LNG-IUD) and a gonadotropin-releasing hormone agonist (GnRHa) on uterine volume, uterine arteries pulsatility index (PI) and endometrial thickness before and after six months of endometriosis treatment. Sixty women aged 18-40 y were allocated randomly to one of two groups: LNG-IUDs were inserted in 30 women, and GnRHa monthly injections were performed on the other 30. All 60 women were submitted to transvaginal 2-D ultrasound scans on the day that the treatment started and then six months later. Measurements of uterine arteries PI, uterine volume and endometrial thickness were performed at both evaluations. The use of LNG-IUDs significantly decreased endometrial thickness (pre = 6.08 +/- 3.00 mm, post = 2.7 +/- 0.98 mm; mean +/- SD), as did the use of GnRHa (pre = 6.96 +/- 3.82 mm, post = 3.23 +/- 2.32 mm). The uterine volume decreased in the GnRHa group (pre = 86.67 +/- 28.38 cm(3), Post = 55.27 +/- 25.52 cm(3)), but not in the LNG-IUD group (pre = 75.77 +/- 20.88 cm(3), post = 75.97 +/- 26.62 cm(3)). Uterine arteries PI increased for both groups; however, the increase was higher in the GnRHa group (0.99 +/- 0.84 vs. 0.38 +/- 0.84, p = 0.007; PI increase in GnRHa and in LNG-IUD groups, respectively). In conclusion, levonorgestrel released directly onto the endometrium by the LNG-IUD induced smaller uterine changes than did the hypoestrogenism induced by GnRHa. Nevertheless, both promoted similar effects on endometrial thickness. (E-mail: wpmartins@gmail.com) (C) 2008 World Federation for Ultrasound in Medicine & Biology.

A menorragia é uma causa importante de ansiedade e desconforto na mulher. Esta patologia diminui a qualidade de vida e aumenta o número de consultas na área da Ginecologia, com consequente aumento de custos. Material e métodos: Foi efectuado um questionário por telefone e na consulta de Ginecologia da MAC, a 54 das 69 mulheres que colocaram sistema intra-uterino com levonorgestrel no período de Setembro de 2002 a Setembro 2004. Foram avaliados os seguintes parâmteros: medicação anterior, padrão hemorrágico, efeitos secundários e grau de satisfação. Resultados: Ocorreu expulsão em 11,6% dos casos. Não houve remoções motivadas por efeitos secundários. O grau de satisfação foi de 90,7%. Em 87% dos casos voltariam a colocar e 83,3% das utentes aconselhariam este método a outra mulher. Conclusão: O sistema intra-uterino com levonorgestrel é bem aceite e tem uma elevada eficácia no controle da menorragia. O spotting pós inserção é mais frequente nos primeiros 6 a 12 meses, levando a uma diminuição da compliance caso não haja uma explicação prévia dos possíveis efeitos secundários.

A menorragia disfuncional constitui uma queixa frequente em mulheres na peri-menopausa, contribuindo para uma morbilidade significativa nesta faixa etária. As alternativas terapêuticas médicas são limitadas, com resultados variáveis. A aprovação do dispositivo com levonorgestrel veio alargar as opções de tratamento não cirúrgico desta situação, assumindo-se actualmente como uma alternativa válida à histerectomia. Os autores fazem uma revisão sobre as principais características do dispositivo intra-uterino com levonorgestrel e apresentam estudos que mostram a eficácia desta forma terapêutica na menorragia disfuncional.

Na Consulta de Ginecologia a menorragia é uma patologia frequente. A terapêutica médica é muitas vezes ineficaz, com recurso a intervenção cirúrgica. Material e Métodos: Foram seguidas prospectivamente 69 mulheres com menorragias, em que foi inserido o dispositivo intra-uterino com levonorgestrel, entre Setembro de 2002 e Setembro de 2004. Foram analisados parâmetros clínicos e laboratoriais que permitiram inferir da evolução do quadro de menorragia, bem como da existência de eventuais efeitos secundários. Resultados: Houve uma redução do fluxo menstrual em 60,6% das mulheres aos 3 meses. Após 12 meses, 37,9% das mulheres estavam em amenorreia. Verificou-se aumento dos níveis de hemoglobina (Hb) e volume globular médio (VGM) durante o primeiro ano. Os efeitos secundários mais comuns foram: mastalgia, cefaleias e dor abdominal, em 16%, 11,6% e 10% das mulheres, respectivamente, com tendência para regredir durante os seis primeiros meses. A taxa de expulsão foi de 13%. Conclusões: O dispositivo intra-uterino com levonorgestrel é uma terapêutica não cirúrgica utilizada no tratamento da menorragia, com eficácia superior à terapêutica oral, constituindo uma alternativa válida à histerectomia. Após a análise dos resultados, verificou-se que houve um aumento dos níveis de Hb e VGM, associado a uma diminuição do fluxo. A libertação directa de levonorgestrel no endométrio tem como vantagem a redução da incidência de efeitos secundários sistémicos. São no entanto necessários mais estudos com maior casuística para confirmar estes resultados.

Objective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.

To compare the cost and effectiveness of the levonorgestrel-releasing intrauterine system (LNG-IUS) versus combined oral contraception (COC) and progestogens (PROG) in first-line treatment of dysfunctional uterine bleeding (DUB) in Spain. STUDY DESIGN: A cost-effectiveness and cost-utility analysis of LNG-IUS, COC and PROG was carried out using a Markov model based on clinical data from the literature and expert opinion. The population studied were women with a previous diagnosis of idiopathic heavy menstrual bleeding. The analysis was performed from the National Health System perspective, discounting both costs and future effects at 3%. In addition, a sensitivity analysis (univariate and probabilistic) was conducted. RESULTS: The results show that the greater efficacy of LNG-IUS translates into a gain of 1.92 and 3.89 symptom-free months (SFM) after six months of treatment versus COC and PROG, respectively (which represents an increase of 33% and 60% of symptom-free time). Regarding costs, LNG-IUS produces savings of 174.2-309.95 and 230.54-577.61 versus COC and PROG, respectively, after 6 months-5 years. Apart from cost savings and gains in SFM, quality-adjusted life months (QALM) are also favourable to LNG-IUS in all scenarios, with a range of gains between 1 and 2 QALM compared to COC and PROG. CONCLUSIONS: The results indicate that first-line use of the LNG-IUS is the dominant therapeutic option (less costly and more effective) in comparison with first-line use of COC or PROG for the treatment of DUB in Spain. LNG-IUS as first line is also the option that provides greatest health-related quality of life to patients.

OBJETIVO: verificar os efeitos do dispositivo intra-uterino (DIU) de levonorgestrel em portadoras de adenomiose, com falhas de implantação em ciclos de fertilização in vitro (FIV). MÉTODOS: foram selecionadas 80 mulheres inférteis, com até 38 anos, com diagnóstico de adenomiose pela ultra-sonografia e ressonância magnética pélvica. Todas apresentavam tentativas anteriores de FIV sem sucesso. No grupo Diu, de 40 mulheres, foi colocado DIU liberador de 20 µg de levonorgestrel/dia por seis meses, previamente a um novo ciclo de FIV. No grupo Fiv, de 40 mulheres, estas foram submetidas diretamente a novo ciclo, sem o prévio tratamento. No Grupo Diu, avaliaram-se o volume uterino, a espessura e os focos de hipersinal da zona juncional, pré e pós-tratamento, assim como as taxas de gravidez em novo ciclo de FIV comparadas com as obtidas no grupo Fiv. As análises estatísticas foram realizadas adotando-se o nível de significância de 5% (p<0,05), sendo aplicados os testes t de Student e Mann-Whitney. RESULTADOS: após o tratamento, verificou-se redução em 77,7% dos casos de adenomiose focal, além de redução considerada significativa do volume uterino e da espessura média da zona juncional de 128,8 para 93,6 mL e de 12,3 para 11,3 mm, respectivamente. No grupo Diu, a taxa de gravidez atingiu 30%, valor superior, embora não de forma significativa, ao encontrado no grupo Fiv, de 17,5%. CONCLUSÃO: o uso do DIU com levonorgestrel pode ser indicado previamente a ciclos de FIV em pacientes portadoras de adenomiose, com falhas de implantação anteriores.

Background: The objective of this study was to evaluate the effect of three contraceptive pills containing ethinylestradiol (EE) (20 or 30 mcg) in combination with drospirenone (DRSP) and levonorgestrel (LNG) on plasma concentration of adhesion molecules vascular cell adhesion molecule -1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and E-selectin. Study Design: A cross-sectional study was conducted with 72 participants (18-30 years old) distributed into three groups that used oral contraceptives containing EE 20 or 30 mcg combined with DRSP 3 mg or EE 30 mcg/LNG 150 mcg for at least 6 months. The control group was comprised of nonusers of contraceptives. Soluble VCAM-1, soluble ICAM-1 and soluble E-selectin were evaluated by enzyme-linked immunosorbent assay. Results: Compared to the control group, a significant decrease was found in VCAM-1 and ICAM-1 concentrations with use of DRSP/20 EE and LNG/30 EE. Conclusions: DRSP/20 EE and LNG/30 EE induce favorable changes in endothelial function. (C) 2012 Elsevier Inc. All rights reserved.

Objective: The primary objective of this project was to describe the efficacy of the Levonorgestrel Intrauterine Device (LIUD) for treatment of Complex Endometrial Cancer (CAH) and Grade 1 Endometrial Cancer (G1EEC) in terms of rate of Complete Response (CR) and Partial Response (PR) after 6 months of therapy. Finally, we assessed if any clinical or pathologic features were associated with response to the LIUD. ^ Methods: This study was a retrospective case series designed to report the response rate of patients with CAH or G1EEC treated with LIUD therapy. In addition, this study has a laboratory component to assess molecular predictors of response to LIUD therapy. Retrospective data already collected from patients diagnosed with CAH or EEC grade 1 and treated with LIUD therapy at MD Anderson Cancer Center (MDACC) were used for this study. Patients from all ethnic and race groups were included. A Complete Response (CR) was defined in patients diagnosed with CAH if pathologic report at 6 months demonstrated either no evidence of hyperplasia or no atypia in the setting of simple or complex hyperplasia. Partial Response (PR) was recorded if disease downgraded to only CAH from G1EEC. No Response (NR) was recorded if pathologic report demonstrates no change (Stable Disease, SD) or progression to cancer (Progressive Disease, PD). We calculated the proportion of patients with complete response to LIUD therapy with 95% confidence interval. We compared the response rates (CR/PR vs NR) by obesity status (Obese if BMI > 40 kg/m2 vs non-obese if BMI <= 40 kg/m2) as well as other clinical and pathologic factors, such as age, uterine size (median size), and presence of exogenous progesterone effect. ^ Results: There were 39 patients diagnosed with either CAH or G1EEC treated with the LIUD. Of 39 patients, 12 did not have pathological results of biopsy at 6months time period. Of 27 evaluable patients, 17 were diagnosed with CAH and 10 with G1EEC. Overall response rate (RR) was 78% (95% CI = 62-94%) at 6 months, 18 patients had CR (4 in G1EEC; 14 in CAH), 3 patients had PR (3 in G1EEC), 3 had SD (1 in CAH; 2 in G1EEC), 3 had PD (2 in CAH; 1 in G1EEC). After histology stratification, RR at 6 months was 82.35% (14/17; 95%CI = 67.4-97.3%) in CAH and 70% (7/10; 95% CI = 41-98.4%) in G1EEC. ^ There was no difference in response (R) and no response (NR) based on BMI (p=0.56). He observed a trend showing association between age with response (p=0.1). There was no association between uterine size and response to therapy (p=0.17). We recorded strong association between exogenous progesterone effect and response. ^ Conclusion: LIUD therapy for the treatment of CAH and G1EEC may be effective and safe. Presence of exogenous progesterone effect may predict the response to LIUD therapy at earlier time points. There is need of further studies with larger sample size to explore the relationship of response with other clinical and pathologic factors^
