Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

Abstract Objective To evaluate whether continuation rates with the 52-mg levonorgestrelreleasing intrauterine system (LNG-IUS) up to 5 years after placement differed between women using the method exclusively for contraception and those using the device for medical reasons alone. Methods A retrospective cohort study was conducted in a family planning clinic with 5,034 LNG-IUS users: 4,287 using the method exclusively for contraception and 747 for medical reasons alone. The continuation rate at 1 to 5 years of use was calculated by life table analysis. Results Initially, the continuation rate was significantly higher in the contraception group: 85.8 versus 83.4 and 77.4 versus 76.0 per 100 women-years in the 1st and 2nd years of use, respectively. There were more discontinuations due to bleeding/spotting in the medical reasons group in the first two years. The discontinuation rate according to reason for use was not significantly different from the third to the fifth year of use. No women discontinued due to amenorrhea in either group. Conclusion The continuation rate was significantly higher in the contraception group in the first two years of use. Amenorrhea was not a reason for discontinuation in either group, suggesting that counselling in this respect was adequate. Nevertheless, counselling could perhaps have been better with regards to the expected long period of bleeding and spotting in the first two years after placement.
Resumo Objetivo Avaliar a taxa de continuação até 5 anos de uso do sistema intrauterino liberador de 52-mg levonorgestrel por dia (SIU LNG) -IUS) é diferente entre mulheres que o usam exclusivamente como anticoncepcional que entre as que usam exclusivamente por razões médicas. Métodos Estudo retrospectivo realizado em uma clínica de Planejamento Familiar 5.034 usuárias de SIU LNG, 4.287 que optaram pelo método apenas como anticoncepcional e 747 que o usavamsomente por razoesmédicas. A taxa de continuação de um até cinco ano foi calculada por meio de análise de tabela de vida Resultados No início a taxa de continuação foi significativamente maior no grupo da anticoncepção: 85,8 versus 83,4 e 77,4 versus 76,0 por 100 anos-mulher no 1° e 2° ano de uso, respectivamente. Houve mais descontinuações por sangrado-manchado no grupo de razões médicas nos dos primeiros anos. A taxa de continuação não foi significativamente diferente desde o terceiro até o quinto ano de uso. Nenhuma mulher de ambos os grupos descontinuou por amenorreia. Conclusão A taxa de continuação foi significativamente maior no grupo de anticoncepção durante os dos primeiros anos de uso. Amenorreia não foi motivo de descontinuação em ambos os grupos, sugerindo que a orientação a esse respeito foi adequada. Entretanto, a orientação referente ao longo período de sangramentos irregulares nos dois primeiros anos após a inserção, precisaria ser melhorado.

Abstract Objectives: to identify the main indications and reasons for discontinuing the use of the Levonorgestrel-Releasing Intrauterine System (LNG-IUS). Methods: a cross-sectional study was carried out from medical records of 327 women who used the LNG-IUS 52mg between January 2011 and December 2016 at a public hospital in the Northeast of Brazil. Results: the main indications for the use of the LNG-IUS were: contraception (32.7%), myoma/metrorrhagia (28.7%) and endometriosis/pelvic pain (22.3%). Of the 327 women, 68 (20.8%) had discontinued using the device. The most frequent reasons for discontinuation were: expulsion (9.2%), LNG-IUS expiration (3.7%), bleeding (2.4%) and pain (1.5%). Most patients had no difficulty in the insertion and did not require anesthesia/sedation. Among the 30 women who expelled the device, 17 (56.7%) had used it for metrorrhagia and myoma, 8 (26.7%) for contraception, and 5 (16.6%) for endometriosis/pelvic pain. Conclusions: the LNG-IUS is a well-accepted contraceptive method, with therapeutic applications for some gynecological conditions and a low expulsion rate.
Resumo Objetivos: identificar as principais indicações e razões para a descontinuação do uso do sistema intra-uterino liberador de levanogestrel (SIU-LNG). Métodos: foi realizado um estudo transversal a partir de prontuários de 327 mulheres que usaram o SIU-LNG 52mg entre janeiro de 2011 e dezembro de 2016 em um hospital público do Nordeste do Brasil. Resultados: as principais indicações para o uso do SIU-LNG foram: contracepção (32,7%), mioma / metrorragia (28,7%) e endometriose / dor pélvica (22,3%). Das 327 mulheres, 68 (20,8%) haviam descontinuado o uso do dispositivo. Os motivos mais frequentes de descontinuação foram: expulsão (9,2%), expiração de SIU-LNG (3,7%), sangramento (2,4%) e dor (1,5%). Conclusão: a maioria dos pacientes não teve dificuldade na inserção e não necessitou de anestesia / sedação. Entre as 30 mulheres que expulsaram o dispositivo, 17 (56,7%) o utilizaram para metrorragia e mioma, 8 (26,7%) para contracepção e 5 (16,6%) para endometriose / dor pélvica. O SIU-LNG é um método contraceptivo bem aceito, com aplicações terapêuticas para algumas condições ginecológicas e baixa taxa de expulsão.

Abstract Objective Changes in bleeding patterns could influence the decisions of healthcare professionals to change the levonorgestrel-releasing intrauterine system (LNG-IUS) before 7 years of use, the recommended period of extended use. We evaluated changes in the bleeding patterns of users of the 52 mg LNG-IUS at the end of use of the first (IUS-1) and during the second device (IUS-2) use. Methods We performed an audit of the medical records of all women who used two consecutive LNG-IUSs at the Family Planning clinic. We evaluated the sociodemographic/gynecological variables, the length of use, and the bleeding patterns reported in the reference periods of 90 days before removal of the IUS-1 and at the last return in use of IUS-2. We used the McNemar test to compare bleeding patterns. Statistical significance was established at p < 0.05. Results We evaluated 301 women aged (mean ± SD) 32 (±6.1) years, with lengths of use of 68.9 (±16.8) and 20.3 (±16.7) months for the IUS-1 and IUS-2, respectively. No pregnancies were reported. Bleeding patterns varied significantly among women who used the IUS-2 for ≥ 7 months to 6 years when compared the bleeding patterns reported in IUS-1 use. Eighty-nine out of 221 (40%) women maintained amenorrhea and infrequent bleeding; 66 (30%) evolved to bleeding patterns with light flow, and 66 (30%) maintained or evolved to heavy flow patterns (p = 0.012). No differences were observed among the 80 women with ≤ 6 months of use. Conclusion Changes in bleeding patterns occur during the use of LNG-IUS and should not be decisive for the early replacement of the device.
Resumo Objetivo Variações no padrão de sangramento podem afetar a decisão de troca do sistema intrauterino de levonorgestrel (SIU-LNG) antes do período de uso estendido recomendado de 7 anos. Nós avaliamos mudanças no padrão de sangramento de usuárias ao final do uso do primeiro SIU-LNG 52 mg (SIU-1) e durante o uso do segundo dispositivo (SIU-2). Métodos Revisamos os prontuários de todas as mulheres que inseriram consecutivamente o SIU-LNG no ambulatório de Planejamento Familiar. Foram avaliadas as variáveis sociodemográficas/ginecológicas, o tempo de uso, e os padrões de sangramento relatados nos períodos de referência de 90 dias antes da remoção do SIU-1 e no último retorno em uso do SIU-2. Usamos o teste de McNemar para comparar os padrões de sangramento. A significância estatística foi estabelecida em p < 0,05. Resultados Analisamos os dados de 301 mulheres com idade (média ± desvio padrão [DP]) de 32 (±6,1) anos e tempo de uso de 68,9 (±16,8) e 20,3 (±16,7) meses para o SIU-1 e SIU-2, respectivamente. Nenhuma gravidez foi relatada. Os padrões de sangramento variaram significativamente durante o uso do SIU-2 (≥ 7 meses a 6 anos) em relação ao padrão relatado no SIU-1. Oitenta e nove das 221 (40%) mulheres mantiveram amenorreia e sangramento infrequente; 66 (30%) evoluíram para padrões de sangramento com fluxo leve e 66 (30%) mantiveram ou evoluíram para padrões de fluxo intenso (p = 0,012). Não foram observadas diferenças entre as 80 mulheres que utilizavam o SIU-2 há ≤ 6 meses. Conclusão Mudanças nos padrões de sangramento ocorrem durante o uso do LNG-IUS e não devem ser decisivas para a troca precoce do dispositivo.

SUMMARY OBJECTIVE: To evaluate endocervical and vaginal environment changes in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: A quasi-experimental study included sixty women who had an LNG-IUS inserted in the Family Planning Clinic of UNICAMP between April and November of 2016. Women in reproductive age, non-pregnant, without the use of antibiotics and contraceptives seeking for LNG-IUS insertion were selected for this study. All women were evaluated with regard to vaginal and endocervical pH, vaginal and endocervical Gram-stained bacterioscopy, and Pap-smear before and two months after LNG-IUS insertion. Clinical aspects such as cervical mucus, vaginal discharge, and cervical ectopy were also observed. RESULTS: After LNG-IUS insertion, there was an increase in the following parameters: endocervical pH>4.5 (p=0.02), endocervical neutrophil amount (p<0.0001), vaginal cytolysis (p=0.04). There was a decrease in vaginal discharge (p=0.01). No statistically significant changes were found in vaginal pH, neutrophils amount in the vaginal mucosa, vaginal discharge appearance, vaginal candidiasis, bacterial vaginosis, vaginal coccobacillary microbiota, cervical mucus appearance, or cervical ectopy size. CONCLUSIONS: Short-term LNG-IUS use did not increase vulvovaginal candidiasis or bacterial vaginosis, and led to diminished vaginal discharge. Notwithstanding, this device promoted reactional changes in the vaginal and endocervical environment, without modification on cervical ectopy size.
RESUMO OBJETIVO: Avaliar as alterações do ambiente endocervical e vaginal em mulheres usuárias de sistema intrauterino liberador de levonorgestrel (SIU-LNG). MÉTODOS: Um estudo quase-experimental incluiu 60 mulheres que inseriram o SIU-LNG na Clínica de Planejamento Familiar da UNICAMP entre abril e novembro de 2016. Mulheres em idade reprodutiva, não gestantes, sem uso de antibióticos e contraceptivos, em busca pela inserção do SIU-LNG, foram selecionadas para este estudo. Todas as mulheres foram avaliadas quanto ao pH vaginal e endocervical, bacterioscopia vaginal e endocervical por coloração de Gram, exame de Papanicolau antes e dois meses após a inserção de SIU-LNG. Aspectos clínicos como muco cervical, corrimento vaginal e ectopia cervical também foram observados. RESULTADOS: Após a inserção do SIU-LNG houve aumento nos seguintes parâmetros: pH endocervical >4,5 (p=0,02), quantidade de neutrófilos endocervicais (p<0,0001), citolise vaginal (p=0,04). Houve diminuição do conteúdo vaginal (p=0,01). Não foram encontradas alterações estatisticamente significativas no pH vaginal, na quantidade de neutrófilos na mucosa vaginal, apecto do corrimento vaginal, candidíase vaginal, vaginose bacteriana, microbiota cocobacilar vaginal, aparência de muco cervical ou tamanho da ectopia cervical. CONCLUSÃO: O uso do SIU-LNG em curto prazo não aumentou a candidíase vulvovaginal ou a vaginose bacteriana, levou à diminuição do conteúdo vaginal. No entanto, este dispositivo promoveu mudanças reacionais no ambiente vaginal e endocervical, sem modificação no tamanho da ectopia cervical.

The activity of matrix metalloproteinases (MMPs) in the uterine flushing and endometrial tissue of normal adult women wearing FCu-IUD (fixed Cu-IUD) or FICu-IUD (indomethacin-releasing FCu-IUD) was observed by using zymography on SDS-PAGE containing gelatin. The results showed that the activity and kinds of MMPs in FCu-IUD group were increased significantly as compared with themselves before being inserted FCu-IUD. However, compared with the FCu-IUD group, the activity of some kinds of MMPs in the FICu-IUD group was decreased significantly. These data suggest that IUD can enhance the activity of MMPs in human endometrium, intermediated by prostaglandins, and MMPs may have relation to IUD-induced menorrhagia and indomethacin reduces IUD-induced menorrhagia by partly inhibiting MMPs synthesis.

The DATTA panelists emphasized the critical importance of patient selection when considering IUDs for contraception The IUD is an acceptable method of contraceptives, in a stable monogamous relationship, and not at risk for sexually transmittel diseases. Within these constraints, the panelists gave overwhelming support to the IUD as a safe and effective method of contraception. The minority opinion (two panelists) that these devices were not established for safety or effectiveness was based on concerns over possible infectious complications.

Estudou-se o efeito da administraçäo de levonorgestrel(L-Ng)por via intra-uterina sobre o sistema reprodutor feminino e seu efeito clínico como anticoncepcional. Para a administraçäo utilizou-se DIUs que liberaram 20 ou 30mcg de L-Ng por dia num período de até 7 anos. Na avaliaçäo clínica o grupo de controle recebeu um T-Cu380Ag, reconhecidamente eficaz. Os resultados mostraram que a via intra-uterina é eficiente para conseguir níveis sanguíneos estaáveis de L-Ng,e que a concentraçäo do hormônio näo é maior no ovário que na circulaçäogeral. O efeito sobre o ovário é a anovulaçäo em alta porcentagem, nos primeirosmeses, depois persiste uma interferência na fase lútea. Concluiu-se que esta via de administraçäo de L-Ng poderá ter uma posiçäo de destaque na anticoncepçäo hormonal e que seus efeitos também poderiam ter aplicaçöes terapêuticas para tratamento local de patologias endometriais
