Title in Portuguese
Efeito do uso de anticoagulante oral sobre o padrão de sangramento associado ao uso do sistema intrauterino liberador de levonorgestrel em mulheres portadoras de trombofilia e/ou com passado de trombose
Keywords in Portuguese
Anticoagulante oral
Mulheres trombofílicas
SIU-LNG
Tromboembolismo venoso
Abstract in Portuguese
Os progestagênios isolados são contraceptivos indicados que em trombofílicas e/ou com passado de tromboembolismo venoso (TEV). Algumas dessas mulheres, também utilizam anticoagulantes orais (ATCO) o que pode implicar em alterações no padrão de sangramento menstrual associado ao uso de progestagênios isolados. Objetivo: avaliar os efeitos do uso de ATCO no padrão de sangramento associado ao sistema intrauterino liberador de levonorgestrel (SIU-LNG) em mulheres trombofílicas e/ou com passado de TEV . Métodos: Trata-se de um estudo de coorte prospectiva que dividiu as mulheres trombofílicas e/ou com passado de TEV em dois grupos, usuárias de ATCO e não-usuárias de ATCO. Padrão de sangramento, peso, índice de massa corpórea (IMC) e circunferência abdominal foram comparados entre os grupos antes, 6 e 12 meses após a inserção do SIU-LNG. Resultados: Foram incluídas 33 mulheres, entre 18 e 45 anos, 16 usuárias de ATCO e 17 não-usuárias. Houve aumento de 3,9% do peso e 3,8% do IMC em das usuárias de ATCO após 12 meses da inserção do SIU-LNG (p<0,01). Houve aumento de hemoglobina e hematócrito em ambos os grupos. Não se observou diferença entre o padrão de sangramento de ambos os grupos, sendo a amenorréia o padrão mais frequente nos dois grupos (41,2% em ambos) 12 meses após a inserção do SIU-LNG. Utilizar ATCO não aumentou a freqüência e a duranção de sangramento genital. Conclusão: As usuárias e não-usuárias de ATCO tiveram padrão de sangramento semelhante após a inserção do SIU-LNG. Os níveis de hemoglobina e hematócrito aumentaram em ambos os grupos

Effect of oral anticoagulant therapy on the pattern of bleeding associated with use of the levonorgestrel-releasing intrauterine system in women with thrombophilia and / or with a history of thrombosis

Abstract in English
Background: Progestogen-only contraceptives (POCs) are suitable for women with thrombophilia and/or a history of venous thromboembolism (VTE). Several of these women, however, use oral anticoagulant therapy (OAT), which can impair the bleeding pattern associated with POC use. We evaluated the effects of OAT use on the bleeding pattern associated with the levonorgestrel-releasing intrauterine system (LNG-IUS) in women with thrombophilia and/or a history of VTE. Study Design: This prospective cohort study followed 2 groups of women, all of whom were thrombophilic and/or had a history of VTE: OAT users and non-users. Bleeding patterns, blood pressure, body mass index (BMI), weight, complete blood count and waist circumference were compared between the 2 groups before and 6 and 12 months after LNG-IUS insertion. Results: The patient cohort consisted of 33 women aged 18 to 45 years old, including 16 OAT users and 17 non-users. Body weight increased by 3.9% and BMI by 3.8% in OAT users 12 months after LNG-IUS insertion (p< 0,01). Hemoglobin and hematocrit levels increased by approximately 10% in both groups. There was no difference between the groups in bleeding patterns, with amenorrhea being the most frequent pattern in both groups (41.2% each) 12 months after LNG-IUS insertion. OAT did not increase the frequency of prolonged and/or frequent bleeding. Conclusion: OAT users and non-users had similar bleeding patterns after insertion of the LNG-IUS. Hemoglobin and hematocrit levels increased in both groups
