Comparative study of the levonorgestrel intrauterine system and laparoscopic hysterectomy for the treatment of heavy menstrual bleeding in enlarged uteri.

OBJECTIVE: The levonorgestrel intrauterine system treatment prevents 67.7% of surgeries in patients with heavy menstrual bleeding and enlarged uteri. To evaluate the effectiveness of the levonorgestrel intrauterine system in the treatment of patients with heavy menstrual bleeding and an enlarged uterus and to compare satisfaction and its complications with hysterectomy. METHODS: This was a comparative cross-sectional observational study of women with heavy menstrual bleeding and an enlarged uterus. Sixty-two women were treated and followed up for four years. Insertion of the levonorgestrel intrauterine system was performed in Group 1, and laparoscopic hysterectomy was performed in Group 2. RESULTS: In Group 1 (n=31), 21 patients (67.7%) showed improvement in the bleeding pattern, and 11 patients (35.5%) had amenorrhea. Five patients (16.1%) remained with heavy bleeding and were considered to have experienced treatment failure. There were seven expulsions (22.6%); in five patients, bleeding remained heavy, but in two patients the bleeding returned to that of normal menstruation. No relationship was found between treatment failure and greater hysterometries (p=0.40) or greater uterine volumes (p=0.50), whereas expulsion was greater in uteri with smaller hysterometries (p=0.04). There were 13 (21%) complications, seven (53.8%) in the group that underwent insertion of the levonorgestrel intrauterine system (all were device expulsions), and six (46.2%) in the surgical group, which were the most severe ones (p=0.76). Regarding satisfaction, 12 patients (38.7%) were dissatisfied with the levonorgestrel intrauterine system and one (3.23%) was dissatisfied with the surgical treatment (p=0.00). CONCLUSION: Treatment with the levonorgestrel intrauterine system in patients with heavy menstrual bleeding and an enlarged uterus was effective, and when compared with laparoscopic hysterectomy, it had a lower rate of satisfaction and the same rate of complications, although less severe.

Uterine volume, menstrual patterns, and contraceptive outcomes in users of the levonorgestrel-releasing intrauterine system: A cohort study with a five-year follow-up.

OBJECTIVE: The aim of our study was to evaluate the effects of the LNG-IUS on uterine volume, bleeding patterns, and LNG-IUS-related outcomes among women using the device to treat abnormal uterine bleeding caused by fibroids, adenomyosis, HMB (without structural cause), or contraception. STUDY DESIGN: This was a 5-year cohort study with LNG-IUS users. We selected 147 women, who were allocated to four groups: a) control (contraception indication); b) fibroids; c) adenomyosis; d) HMB. The visits for clinical and ultrasound evaluations were made at baseline and at 3, 6, 12, 24, 36, 48, and 60 months postinsertion. All data are expressed as mean and standard deviation (SD) or absolute and relative (%) frequency. Differences among groups were established by using the χ2 (chi-square) test and Fisher's exact tests for categorical outcomes, as well as the Mann-Whitney and the Kruskal-Wallis tests and Friedman's ANOVA for continuous variables. We used the 5% significance level as an indication of statistical significance. Logistic regression analyses were performed to study the association between predictors and outcomes. Results are expressed as odds ratios (ORs) with a 95% confidence interval (CI 95%). RESULTS: Although all groups had real rates of bleeding patterns, troublesome bleeding appeared to be more frequent in the fibroid group (∼15%). Also, along the 60 months of follow-up, uterine volume slightly decreased in the groups of HMB, adenomyosis, and fibroids, but not in the contraception group. However, the isolated volume of fibroids remained unchanged. In this cohort, we observed high continuation rates among LNG-IUS users. The uterine volume ≥200 cm3 was the main predictor of hysterectomy or IUS expulsion in the adenomyosis and fibroid groups. CONCLUSION: The LNG-IUS may control uterine menstrual bleeding as well as uterine volume in adenomyosis, fibroids, and HMB. An initial uterine volume smaller than 200 cm3 is an important predictor of adherence to treatment and better outcomes.

Depression in Female Adolescents with Heavy Menstrual Bleeding.

OBJECTIVE: To assess the degree to which heavy menstrual bleeding is associated with depression, independent of hormonal contraception. STUDY DESIGN: We performed a retrospective cohort study of 1168 female adolescents 9-18 years old presenting to general pediatricians for heavy menstrual bleeding or well visits. Depression was the primary outcome and defined as a diagnosis in the health record. Univariable and multivariable regression models were fit to the data to identify factors associated with depression diagnosis. RESULTS: In total, 581 adolescents with heavy menstrual bleeding and 587 without heavy menstrual bleeding were included. Depression diagnoses occurred with greater frequency in youth with heavy menstrual bleeding compared with those without heavy menstrual bleeding (50.9% vs 24.2% P < .001; risk ratio 1.67, 95% CI 1.39-2.01) but did not significantly differ between those taking vs not taking hormonal contraception (risk ratio 0.99; 95% CI 0.84-1.17). Most patients with depression and heavy menstrual bleeding developed depression following or concurrent with heavy menstrual bleeding (261/296, 88%). Of these, 199 of 261 (76%) were treated with hormonal contraception, but the majority (168/199; 84%) were diagnosed with depression before initiation. CONCLUSIONS: Heavy menstrual bleeding is associated with depression diagnosis in female adolescents. The use of hormonal contraception was not associated with depression diagnosis in multivariable analysis, covarying heavy menstrual bleeding, age, body mass index, anxiety, sexual activity, and substance use. As hormonal contraception is often used to treat heavy menstrual bleeding, heavy menstrual bleeding may be partially driving previous reports of increased depression risk in those taking hormonal contraception.

The difficult journey to treatment for women suffering from heavy menstrual bleeding: a multi-national survey.

PURPOSE: Up to 30% of women of reproductive age experience HMB, which has a substantial impact on their quality of life. A clinical care pathway for women with HMB is an unmet need, but its development requires better understanding of the factors that characterise current diagnosis and management of the condition. MATERIALS AND METHODS: This observational, survey-based study assessed the burden, personal experiences, and path through clinical management of women with HMB in Canada, the USA, Brazil, France and Russia using a detailed, semi-structured online questionnaire. After excluding those reporting relevant organic pathology, responses to the questionnaire from 200 women per country were analysed. RESULTS: Around 75% of women with HMB had actively sought information about heavy periods, mostly through internet research. The mean time from first symptoms until seeking help was 2.9 (Standard deviation, 3.1) years. However, 40% of women had not seen a health care professional about the condition. Furthermore, 54% had never been diagnosed or treated. Only 20% had been diagnosed and received appropriate treatment. Treatment was successful in 69% of those patients currently receiving treatment. Oral contraceptives were the treatment most commonly prescribed for HMB, although the highly effective levonorgestrel-intrauterine system was used by only a small proportion of women. CONCLUSIONS: This study provides insight into the typical journey of a woman with HMB which may help patients and health care professionals improve the path to diagnosis and treatment, although further research with long-term outcomes is needed.

Use of a levonorgestrel 52-mg intrauterine system in the control of abnormal uterine bleeding in women with inherited bleeding disorders.

OBJECTIVE: To evaluate the efficacy of a levonorgestrel 52-mg intrauterine system (LNG 52-mg IUS) in controlling abnormal uterine bleeding and improving quality of life in women with inherited bleeding disorders. STUDY DESIGN: We assessed 20 participants laboratory diagnosed with inherited bleeding disorders, who presented with abnormal uterine bleeding and were registered in a Central Blood Center. The primary outcomes were menstrual bleeding volume and quality of life before and after LNG 52-mg IUS placement. We used the Pictorial Blood Loss Assessment Chart (PBAC) score for measuring menstrual bleeding and the Short Form-36 Health Survey to assess quality of life before and after LNG 52-mg IUS placement. We also conducted blood tests to evaluate the hematimetric level. Follow-up visits were conducted at 1, 3, 6, and 12 months after LNG 52-mg IUS placement. Statistical analyses were performed using the Friedman non-parametric test. RESULTS: The use of LNG 52-mg IUS reduced uterine bleeding in women with inherited bleeding disorders. The median PBAC score was higher before LNG 52-mg IUS placement than at 3, 6, and 12 months after placement (p < 0.001). The amenorrhea rate was 70% after 12 months. There was an improvement in all eight parameters of quality of life (p < 0.001). The mean hemoglobin, ferritin, and serum iron levels were also higher at 12 months than before LNG 52-mg IUS placement. CONCLUSION: LNG 52-mg IUS placement can effectively control abnormal uterine bleeding in women with inherited bleeding disorders and consequently improve their quality of life. IMPLICATIONS: The results from our study suggest that women with inherited bleeding disorders who present with heavy menstrual bleeding can benefit from the use of a levonorgestrel-releasing intrauterine system similar to women without bleeding disorders.

Combined oral contraceptive for treatment of women with uterine fibroids and abnormal uterine bleeding: a systematic review.

BACKGROUND/AIMS: We aimed at assessing the efficacy of combined oral contraceptives (COC) in treating women with uterine leiomyomata and heavy menstrual bleeding (HMB), as well as their effect over quality of life (QoL), tumor size, and hemoglobin concentration. METHODS: We searched various electronic databases and reference lists from all included studies. Randomized and nonrandomized controlled clinical trials were selected, and two trials were considered eligible - one randomized and one 'pseudo'-randomized. RESULTS: COCs performed less well than levonorgestrel-releasing intrauterine systems (LNG-IUSs) in controlling HMB, improving QoL, and improving the hemoglobin concentration, whereas the estimate was not sufficiently precise to define whether COCs were better than, equal to, or worse than LNG-IUSs in reducing tumor size. It must be stressed that these results are based on low-quality evidence, stemming from a single trial. Additionally, COCs were more effective than placebo in tumor size reduction, another conclusion based on another single study, considered as being at a high risk of bias and judged as very low-quality evidence. CONCLUSION: Evidence regarding the use of COCs as treatment for women with symptomatic fibroids is very scarce and of low quality, and we are very uncertain about the real efficacy of such treatment.

Sistema intrauterino liberador de levonorgestrel para o tratamento da menorragia idiopática / Levonorgestrel-releasing intrauterine system for the treatment of idiopathic menorrhagia

A DOENÇA: Aspectos clínicos e epidemiológicos da doença: A menorragia é clinicamente definida como a perda sanguínea, durante o período menstrual, excessiva em quantidade ou número de dias (definidos como habituais naquela mulher). O sangramento excessivo é considerado na maioria dos casos, aquele que envolvem uma perda de sangue menstrual maior que 80 ml. Em um sentido mais amplo, a menorragia também é definida como a perda excessiva de sangue menstrual que interfere com a qualidade física, social, emocional e /ou material de uma mulher. Isso pode ocorrer por si só ou em combinação com outros sintomas. Esta condição não está associada com uma mortalidade significativa, no entanto, trata-se de causa comum de procura ao ginecologista. Deve-se distinguir a menorragia de outros diagnósticos ginecológicos comuns. Isso inclui a metrorragia (perda sanguínea, de origem corporal, fora do período menstrual), menometrorragia (perda sanguínea irregular e prolongada) e polimenorréia (sangramento com intervalos menores do que 21 dias). Muitas vezes estes termos recebem descrições e definições conflitantes. Em boa parte das mulheres que sofrem de menorragia, as patologias ou causas que levam à perda excessiva de sangue não podem ser identificadas, justificando dessa forma a denominação menorragia idiopática. . Esse diagnóstico é firmado após a realização de exames diagnósticos, como a ultrassonografia, e o descarte de outras condições que poderiam levar à desregulação ou sangramento em excesso, como endometriose, terapia de reposição hormonal, dentre outros. Outras causas como complicações da gestação (ectópica, aborto), doenças pélvicas (mioma, pólipo endometrial ou cervical, adenomiose, cervicite, grave infecção vaginal, carcinoma do trato reprodutivo, hiperplasia endometrial), doenças sistêmicas (distúrbios hemostáticos, distúrbios da tireóide, lúpus eritematoso sistêmico, insuficiência renal crônica, insuficiência hepática) e causas iatrogênicas (hormonioterapia, contraceptivos injetáveis, medicamentos como tranquilizantes, antidepressivos, anticoagulantes e corticoides) também devem ser afastadas. Os dados epidemiológicos da menorragia idiopática são bastante imprecisos, pela própria subjetividade ou dificuldade em se determinar um sangramento menstrual excessivo. Assim, os estudos trazem acometimentos entre 8,0-51,6% de mulheres com uma maior prevalência em mulheres com idade mais avançada. No Brasil, não há uma estatística nacional sobre a doença, mas um estudo realizado em 2011 na cidade de Pelotas-RS mostrou que a prevalêcia de mulheres com menorragia atendidas pelo SUS de 2006 a 2011 foi de 35,3%, com maior prevalência entre as mulheres mais velhas e com elevado número de gravidezes. TRATAMENTO RECOMENDADO: O tratamento médico da menorragia pode envolver tratamentos farmacológicos ou cirúrgicos, e a escolha do tratamento adequado deve levar em conta algumas condições individuais das mulheres, como idade, doença concomitantes, tratamentos anteriores, opção pela fertilidade e o próprio custo do tratamento, que estará relacionado à sua adesão ao tratamento. Como alternativas de tratamento para a menorragia temos: Antiinflamatórios não esteróides, Contraceptivos orais, Terapia com prostagênio, Agonistas do hormônio liberador de gonadotrofina, Danazol, Estrogênios conjugados, Ácido tranexâmico, Sistema intra-uterino liberador de levonorgestrel (SIU-LNG), Curetagem, Ablação endometrial, Histerectomia. A TECNOLOGIA: Levonorgestrel - O levonorgestrel é um progestógeno com atividade anti-estrogênica utilizado em ginecologia de diversas formas: como componente progestogênico em contraceptivos orais e na terapia de reposição hormonal ou isoladamente para contracepção em pílulas contendo somente progestógeno e implantes subdérmicos. O lenorgestrel também pode ser administrado na cavidade uterina por meio de um endoceptivo (SIU) possibilitando o uso de doses menores, com liberação diretamente no órgão-alvo. EVIDÊNCIAS CIENTÍFICAS: Além da análise dos estudos apresentados pelo demandante, a Secretaria-Executiva da CONITEC realizou busca na literatura por artigos científicos, com o objetivo de localizar a melhor evidência científica disponível sobre o tema. Para isso, foi considerada a estratégia de busca descrita no Quadro 3, tendo como principal critério de inclusão o tipo de estudo considerado a melhor evidência para avaliar a eficácia de uma tecnologia para tratamento, isto é, revisões sistemáticas e ensaios clínicos randomizados (ECR). Outro critério de inclusão foi estudos que avaliassem a eficácia e/ou segurança do dispositivo intrauterino liberador de levonorgestrel no tratamento de Menorragia Idiopática. Alguns critérios de exclusão foram estabelecidos: registros de ensaios controlados em andamento, revisões narrativas, estudos sobre outros medicamentos que não o de interesse, estudos que incluam outras indicações do medicamento, estudos de biologia molecular ou ensaios pré-clínicos (com modelos animais), estudos fase I/II, estudos sem grupo comparador, relatos ou séries de casos, e estudos escritos em outro idioma que não inglês, português ou espanhol. Não houve restrições com relação à data de publicação, sendo resgatados artigos até a data de 29/01/2013. CONSIDERAÇÕES FINAIS: As evidências atualmente disponíveis sobre eficácia e segurança do sistema intrauterino liberador de levonorgestrel 52mg mostram que o produto apresentou-se como alternativa possível a mulheres com menorragia idiopática, com resultados de redução do sangramento menstrual superior ao das terapias farmacológicas existentes e, em termos de melhora na qualidade de vida, similares ao da histerectomia, alternativa cirúrgica padrão-ouro com 100% de eficácia. No entanto, a evidência comparando diretamente os desfechos entre o uso do SIU-LNG e a histerectomia ainda é escassa, e não demonstrou superioridade em relação à histerectomia sob qualquer aspecto, sugerindo-se que estudos de longo prazo sejam realizados para avaliar as taxas de permanência e satisfação com o dispositivo, e se o tratamento cirúrgico está sendo de fato evitado ou apenas postergado. Mesmo considerando o fato de que a opção pelo SIU-LNG é menos invasiva e com menor potencial para complicações do que o procedimento cirúrgico da histerectomia, observou-se nos estudos uma alta taxa de descontinuação do uso do SIU-LNG pelas mulheres e posterior opção pela cirurgia. Considerando todas as limitações metodológicas e de impacto orçamentário, os resultados sugerem que a tecnologia demandada, no contexto do Sistema Único de Saúde, não apresentou superioridade clínica e pode não ser mais custo-efetiva que a histerectomia, procedimento padrão já incorporado ao SUS, com similaridade em relação aos aspectos de qualidade de vida, além de maior eficácia. Assim, o conjunto de argumentos à disposição configura-se como insuficiente para assegurar que a incorporação do produto, dentro da indicação e escopo oferecidos, apresenta reais e inequívocas vantagens para o sistema de saúde público brasileiro. DELIBERAÇÃO FINAL: Na 15º reunião ordinária, os membros do plenário da CONITEC discutiram todas as contribuições da consulta pública, no entanto nenhuma delas trouxe informações ou dados relevantes para a mudança da decisão. Houve consenso que o SIU-LNG não se aplica a toda a população-alvo apresentada pelo demandante, e que o SUS dispõe de outras opções terapêuticas farmacológicas para o tratamento desta condição, nos casos em que não é necessária a histerectomia. Assim, os membros da CONITEC presentes na 15º reunião ordinária, ratificaram, por unanimidade, a deliberação de não recomendar a incorporação do sistema intrauterino liberador de levonorgestrel 52mg para o tratamento da menorragia idiopática. DECISÃO: PORTARIA Nº 31, de 3 de julho de 2013 - Torna pública a decisão de não incorporar o sistema intrauterino liberador de levonorgestrel para o tratamento da menorragia idiopática no Sistema Único de Saúde (SUS).

Mifepristone for uterine fibroids.

BACKGROUND: Uterine fibroids are the most common benign uterine tumours present in women of reproductive age. Mifepristone (RU-486) competitively binds and inhibits progesterone receptors. Studies have suggested that fibroid growth depends on the sexual steroids. Mifepristone has been shown to decrease fibroid size. This review summarises the effects of mifepristone treatment on fibroids and the associated adverse effects as described in randomised controlled trials. OBJECTIVES: To determine the efficacy and safety of mifepristone for the management of uterine fibroids in pre-menopausal women. SEARCH METHODS: We searched the specialised register of the Cochrane Menstrual Disorders and Subfertility (Cochrane Menstrual Disorders and subfertility Review Group), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4), MEDLINE, EMBASE, PsycINFO, and CINAHL (to November 2011). We handsearched a number of journals, and searched reference lists, databases of ongoing trials and the Internet. There were no language restrictions. SELECTION CRITERIA: Only truly randomised controlled trials of mifepristone versus other forms of medical therapy or placebo in pre-menopausal women with confirmed uterine fibroids were included. DATA COLLECTION AND ANALYSIS: Four authors independently extracted data and assessed trial quality. Data were analysed using the Peto odds ratios (OR) for dichotomous data and the weighted mean differences for continuous data, with 95% confidence intervals (CI). Meta-analyses were performed using the fixed-effect model. MAIN RESULTS: Three studies involving 112 participants were included. Comparison interventions included different dosages of mifepristone, placebo and vitamin B tablets. There is evidence that treatment with mifepristone relieves heavy menstrual bleeding compared with placebo (Peto OR 17.84; 95% CI 6.72 to 47.38; 2 RCTs, 77 women, I(2) = 0%). Three studies (Bagaria 2009; Engman 2009; Fiscella 2006) were included in the meta-analysis of this comparison. There was no evidence of an effect of mifepristone on the fibroid volume (standardised mean difference (SMD) -0.02; 95% CI -0.38 to 0.41; 99 women). Two studies (Bagaria 2009; Fiscella 2006) were included in the meta-analysis of this comparison. There was no evidence of an effect of mifepristone on uterine volume (mean difference (MD) -77.24; 95% CI -240.62 to 86.14; 72 women). The pooled data suggest an increased adverse event (abnormal endometrial histology) in the mifepristone group compared to placebo (OR 31.65; 95% CI 4.83 to 207.35; 2 RCTs; 54 women; I(2) = 0%). Only one study (Bagaria 2009) reported endometrial hyperplasia at the end of the therapy (12/19 women in the mifepristone group versus 0/16 in the placebo group; OR 55.0; 95% CI 2.86 to 105.67). Engman 2009 found a significantly higher rate of cystic glandular dilatation in women in the mifepristone group (5/8 women biopsied) compared with the placebo group (1/11 women biopsied) (OR 16.67; 95% CI 1.36 to 204.03). One study (Fiscella 2006) suggested significant improvements (P < 0.001) for specific quality of life outcomes. AUTHORS' CONCLUSIONS: Mifepristone reduced heavy menstrual bleeding and improved fibroid-specific quality of life. However, it was not found to reduce fibroid volume. Further well-designed, adequately powered RCTs are needed before a recommendation can be made on the use of mifepristone for the treatment of uterine fibroids.

Efetividade do dispositivo intrauterino liberador de levonorgestrel (Mirena®) para a terapia de reposição hormonal na perimenopausa e pós-menopausa. / The effectiveness of the levonorgestrel-releasing intrauterine system (Mirena®) for hormone replacement therapy in the peri- and postmenopausal women

A utilização do dispositivo intrauterino (DIU) hormonal para a contracepção é uma constante no consultório de ginecologia da atualidade. Entretanto, outras indicações como o tratamento de algumas patologias ginecológicas benignas, e mais recentemente, o uso para terapia de reposição hormonal (TRH) no climatério têm chamado a atenção. Esta revisão tem como objetivo demonstrar os achados dos artigos publicados, desde 2001, sobre a avaliação do DIU de levonorgestrel (LNG) durante esta fase de turbulência hormonal feminina. No período do climatério, a mulher com útero intacto ganha vários benefícios com essa nova modalidade terapêutica associada ao estrogênio nas suas diversas formas de apresentação. Pode-se concluir que o DIU com LNG na mulher da perimenopausa e pós-menopausa pode ser utilizado para contracepção, alívio de sintomas vasomotores quando associado à terapia com estrogênio e alta resolutividade nos quadros de menorragia que frequentemente acometem a mulher durante esta fase da vida

There is a wide use of the levonorgestrel-releasing intrauterine system (LNG IUS) in recent years for hormonal contraception. However, other indications, as the treatment of some benign gynecological diseases and, more recently, for hormone replacement therapy in peri and postmenopausal women have happened. This review aimed to demonstrate the findings of articles published since 2001 on the use of the LNG IUS in the women's climacteric period. During this phase of life, women with intact uterus benefit of using this new modality of therapy associated with estrogen in their several forms of presentation. It can be concluded that LNG IUS in the peri and postmenopausal women can be used as a contraceptive method, to abbreviate hot flashes symptoms when associated with estrogen therapy and to solve menorrhagia that is a very common finding in this period

Activation of NF-kappaB and COX-2 expression is associated with breakthrough bleeding in patients using oral contraceptives in extended regimens.

The objective of the present study was to determine whether there is an increase in endometrial inflammation associated with the occurrence of breakthrough bleeding in patients using an oral contraceptive in extended regimens. The presence of nuclear factor NF-kappaB and Cox-2 expression was determined by immunohistochemistry in endometrial samples removed by hysteroscopy from patients with breakthrough bleeding during continuous use of an oral contraceptive containing gestodene. All patients had a history of menorrhagia associated or not with the presence of uterine pathology. The percentage of endometria showing a positive staining reaction for NF-kappaB in cell nuclei was significantly higher in patients with breakthrough bleeding than in those with amenorrhea. Cox-2 expression in the endometrium was also significantly more frequent in patients with breakthrough bleeding. The occurrence of breakthrough bleeding in patients with uterine pathology using combined oral contraceptives is associated with the activation of endometrial inflammation through the NF-kappaB pathway.

Menstrual blood loss in women using the frameless FibroPlant LNG-IUS.

BACKGROUND: This study was conducted to report on a menstrual blood loss (MBL) study and iron stores in women with and without heavy menstrual bleeding using the frameless FibroPlant levonorgestrel-releasing intrauterine system (LNG-IUS) for contraception. STUDY DESIGN: An open, prospective, noncomparative MBL study, using FibroPlant releasing 14 mcg of LNG/day for contraception. MBL was assessed by the quantitative alkaline hematin (QAH) technique. RESULTS: The MBL study was conducted in 40 heavy and normally menstruating Brazilian women seeking contraception. MBL was reduced from a mean baseline menstrual volume of 29.7 mL to a mean volume of 1.5 mL after 24 months, while ferritin values increased from a mean value of 31.1 ng/mL (at baseline) to a mean level of 72.5 ng/mL (after 24 months of use). Differences were highly significant (p<.0005). There were no significant differences between those who had normal menstrual bleeding and the heavy bleeders. The heavy bleeders had comparable MBL to the normal bleeders 3 months after insertion, and by 24 months post-insertion, their ferritin levels were comparable to those of the normal bleeders. Amenorrhea occurred in 80% of women out of 40 after 24 months of use. No pregnancies were recorded. CONCLUSION: The LNG-IUS is effective in reducing MBL in normally menstruating women as well as in women with heavy menstrual bleeding. The authors agree with the recommendations by the UK National Institute for Clinical Effectiveness and the new Finnish guidelines for heavy menstrual bleeding that the LNG-IUS should be positioned as first-line treatment prior to endometrial ablation or hysterectomy.

Levonorgestrel-releasing intrauterine system: uses and controversies.

This article provides a perspective on the use of the levonorgestrel-releasing intrauterine system as a contraceptive method and as therapy in different situations, as well as presenting the corresponding controversies and unresolved issues. All studies have reported high contraceptive efficacy, an improvement in menstrual blood loss in women with idiopathic menorrhagia, menorrhagia due to thrombophilic diseases and fibroids, and excellent endometrial protection during postmenopausal estrogen therapy. Moreover, the device is able to reduce pelvic pain and dysmenorrhea as well as improve the staging of endometriosis and adenomyosis, and to control, albeit partially, endometrial hyperplasia. The expectation is that in years to come the number of hysterectomies and female sterilizations will fall due to increased use of the device, including use by patients with endometriosis and HIV-positive women. It would also be desirable to develop a smaller device for postmenopausal women and nulligravidas.

Non-contraceptive health benefits of oral contraceptives.

The use of combined oral contraceptives (COCs) is associated with a reduced risk of developing endometriosis, myomas, and endometrial and ovarian carcinoma. The mechanisms involved are multiple; next to ovulation suppression, a reduction in inflammation in the genital tract is involved. This is accomplished through inhibition of the endometrial expression of enzymes related to the biosynthesis of prostaglandin and oestrogen, particularly cyclooxygenase type II (Cox-2) and aromatase. The blockade of these enzymatic systems by COCs explains the beneficial effects of these compounds in treating the symptoms, and halting the progression of myomas, endometriosis and adenomyosis, all of which are characterized by increased inflammation. Inhibition of aromatase and Cox-2 expression in the endometrium by COCs may explain their efficacy in controlling the pain and excessive uterine bleeding caused by these pathologies. The reduction of inflammation in the endometrium may also be the mechanism behind the lower incidence of endometrial carcinoma in COC users. The blockade of ovulation and ovarian steroidogenesis, on the other hand, may explain the lesser incidence of ovarian cancer and the improvement of acne in users. In conclusion, inflammation appears to play a pivotal role in the development of various benign and malignant gynecological diseases. COCs reduce inflammation in the female genital tract by blocking enzymes such as Cox-2 and aromatase.

Uterine volume and menstrual patterns in users of the levonorgestrel-releasing intrauterine system with idiopathic menorrhagia or menorrhagia due to leiomyomas.

BACKGROUND: A prospective cohort study was carried out to evaluate uterine volume and the volume of uterine leiomyomas in women using the levonorgestrel intrauterine system (LNG-IUS) to treat idiopathic menorrhagia (n=32) and menorrhagia due to leiomyomas (n=27). A control group used the device as a contraceptive method (n=28). METHODS: Clinical and ultrasonographic evaluations were carried out at insertion and at 3, 6, 12, 24 and 36 months later. Total uterine volume and the volume of the leiomyomas were calculated using the ellipsoid formula (anteroposterior diameter)x(transverse diameter)x(longitudinal diameter)x(4/3)x(pi). In the case of multiple leiomyomas, the volume of each myoma was added to calculate the total volume of leiomyomas in each patient. Menstrual bleeding episodes were recorded. RESULTS: Uterine volume decreased significantly in both groups of menorrhagic patients but not in the control group. In the group of women with idiopathic menorrhagia, a mean reduction of 36.4+/-15.3 (S.D.) cm3 (from 127.1 cm3 to 90.7 cm3) was observed (p=.041), and a greater and more significant mean reduction of 63.6+/-19.0 (S.D.) cm3 (from 156.6 cm3 to 93 cm3) occurred in the group of women with leiomyomas (p=.014). In the contraception group, the reduction was of only 2.9+/-5.4 (S.D.) cm3 in mean uterine volume (from 70.3 cm3 to 67.4 cm3), which was not statistically significant (p=.085). The mean volume of leiomyomas decreased by 5.2+/-3.1 (S.D.) cm3 (from 12.8 cm3 to 7.6 cm3 after 3 years of use, but this difference was not significant (p=.4099). After 36 months of use, amenorrhea and oligomenorrhea were the most frequent bleeding patterns, occurring in 45-57% and 33-39% of users in the three groups, respectively. Amenorrhea was higher in the contraception group (57.1%) and in women with idiopathic menorrhagia (53.4%) than women in the group with menorrhagia due to leiomyomas (44.5%) (p=.027). Moreover, the prevalence of spotting was almost three times higher (11%) in women with menorrhagia caused by leiomyomas and nearly double (7.7%) in the idiopathic menorrhagia group when compared with 4% in the control contraception group (p=.024). CONCLUSION: The LNG-IUS significantly reduces uterine volume in women with menorrhagia with and without leiomyoma; however, it does not significantly reduce the volume of leiomyomas.

Uso del DIU con levenorgestrel como alternativa a la histerectomía en pacientes con alto riesgo quirúrgico / Levonorgestrel-releasing intrauterine device (LNG-IUD) as an alternative to hysterectomy in high-risk-surgical patients

Presentamos nuestra experiencia de 6 pacientes con metrorragia a repetición, portadoras de patologías médicas que representaban un riesgo desde el punto de vista anestésico y quirúrgico, en las cuales se insertó DIU-LNG como alternativa a la histerectomía. Todas evolucionan satisfactoriamente y sin complicaciones, con disminución significativa de las pérdidas hemáticas desde el tercer mes de uso, objetivadas por pictogramas. Se concluye que el DIU-LNG es un excelente método para el control de metrorragias en pacientes con patologías médicas relevantes.

We present our experience with 6 patients with menorrhagia and medical conditions considered high risk patients for anaesthesia and surgical procedures. We inserted LNG-IUD as alternative to hysterectomy. Three months later, all of them reduced menstrual blood loss as it was shown by pictorial charts, without complications. LNG-IUD is an excellent alternative to hysterectomy in this group of patients.

Use of a levonorgestrel-releasing intrauterine device for the symptomatic treatment of uterine myomas.

OBJECTIVE: To assess the effect of a levonorgestrel-releasing intrauterine device (LNG-IUD) for the treatment of women with uterine myomas with increased bleeding by measuring total uterine volume and by determining patient clinical improvement, uterine artery flow velocity and hemoglobin levels. STUDY DESIGN: Ten patients with a complaint of increased uterine bleeding associated with the presence of uterine myomas were assessed in a descriptive case series and studied before and 6 months after placement of an LNG-IUD. The patients were assessed for intensity of bleeding, uterine volume, Doppler velocimetry of the uterine arteries, hematocrit and hemoglobin. RESULTS: One patient asked to be released from the study 15 days after LNG-IUD insertion, claiming the occurrence of increased bleeding, and 2 patients underwent spontaneous expulsion of the device after 2 and 4 months of follow-up. Of the 7 patients who continued the study, 3 started to present a bleeding pattern of the oligomenorrhea type, and the other 4 experienced amenorrhea. All patients (n = 6) with anemia at the beginning of the study presented normalization of hematocrit and hemoglobin levels after 6 months of treatment (p=0.0003 and p <0.0001, respectively). However, we observed no reduction in uterine volume (p = 0.11) or flow velocity assessed by the uterine artery pulsatility index (right, p=0.17; left, p=0.19) and of the series resistance index (right, p = 0.54; left, p =0.31) using Doppler velocimetry. CONCLUSION: Use of an LNG-IUD may be effective in controlling uterine bleeding secondary to myomatosis even in the absence of reduction of uterine volume.
