O uso de métodos contraceptivos hormonais em pacientes com asma: repercussões clínicas / The use of hormonal contraceptives methods in patients with asthma: clinical repercussions

Objetivo: Analisar o uso dos contraceptivos hormonais em mulheres com asma e a escolha desses métodos contraceptivos para essa população, com avaliação de eventuais repercussões sobre novos episódios de asma e sibilos. Métodos: Foram selecionados estudos longitudinais, ensaios clínicos, revisões sistemáticas e metanálises. As plataformas consultadas foram PubMed, Embase, Cochrane e SciELO, com a utilização dos descritores: "contracepção", "contracepção hormonal", "sistema intrauterino liberador de levonorgestrel" e "asma". Resultados: Dois grandes estudos demonstraram que o uso de contraceptivos hormonais esteve associado à redução do risco de novos episódios de asma. Uma revisão sistemática concluiu que os resultados para o uso de contraceptivos hormonais para mulheres com asma foram mistos, com aumento ou redução dos seguintes riscos: novo episódio de asma e aumento da frequência das crises e dos sibilos. O uso da contracepção hormonal em pacientes obesas portadoras de asma é controverso. Conclusão: Os resultados para o uso de contraceptivos hormonais em mulheres com asma são inconsistentes, com relatos de aumento ou de redução do risco de novos episódios. O uso do método contraceptivo deve ser discutido individualmente, levando-se em consideração outros fatores de risco associados e o desejo da mulher. A paciente deverá ser orientada se houver piora dos sintomas clínicos de asma na vigência do uso de qualquer método contraceptivo hormonal.

Objective: To analyze the use of hormonal contraceptives in women with asthma and the choice of this contraceptive method for this population, evaluating possible repercussions on new episodes of asthma and wheezing. Methods: Longitudinal studies, clinical trials, systematic reviews and meta-analyses were selected. Platforms consulted: PubMed, Embase, Cochrane, SciELO, using the descriptors: "contraception", "hormonal contraception", "levonorgestrel-releasing intrauterine system" and "asthma". Results: Two large studies demonstrated that the use of hormonal contraceptives was associated with a reduced risk of new episodes of asthma. A systematic review concluded that the results for the use of hormonal contraceptives for women with asthma were mixed, with increased or decrease in the following risks: new asthma episodes, increased frequency and wheezing. The use of hormonal contraception in obese patients with asthma is controversial. Conclusion: The results for the use of hormonal contraceptives in women with asthma are inconsistent, with reports of increased or reduced risk of new episodes. The use of the contraceptive method should be discussed individually, taking into account other associated risk factors and the woman's desire. The patient will be advised if there is a worsening of the clinical symptoms of asthma while using any hormonal contraceptive method.

Use of 52-mg Levonorgestrel-Releasing Intrauterine System in Adolescents and Young Adult Women: 3-Year Follow-Up.

STUDY OBJECTIVE: To evaluate continuance rates, bleeding patterns, and patient satisfaction with 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) use in adolescents and young adult women during the first 3 years of use DESIGN: We conducted an observational prospective study. SETTING: Family Planning Service of a tertiary hospital in Brazil PARTICIPANTS: One hundred adolescents and young women aged 16-24 years. INTERVENTION: Insertion of 52-mg LNG-IUS for the main purpose of contraception. Follow-up visits were conducted at 12, 24, and 36 months after insertion. MAIN OUTCOME MEASURES: Continuance rates, reasons for discontinuation of the method, and women's satisfaction and bleeding patterns RESULTS: Among those who were not lost to follow-up, LNG-IUS continuance rates were 89.1% (82/92), 82.9% (72/87), and 75.3% (64/85) in the first, second, and third years of use, respectively. The main reason for discontinuation was acne, followed by expulsion of/malpositioned LNG-IUS. Other reasons for discontinuation were irregular uterine bleeding, dysmenorrhea, and abdominal pain. The amenorrhea rates were 50%, 54.1%, and 39% at 12, 24, and 36 months, respectively. Spotting rates increased during the first 3 years of use (20.8%, 16.7%, and 26.6%, respectively). Adolescents and young women using the LNG-IUS showed high rates of satisfaction, with 93.9%, 100%, and 96.8% of women being very satisfied/satisfied in the first 3 years of use. Only 2 participants who continued using the LNG-IUS reported being very dissatisfied/dissatisfied in the third year of follow-up. CONCLUSION: The LNG-IUS showed high rates of continuation and satisfaction in the first 3 years of use in Brazilian adolescents and young adults. Most women reported a favorable bleeding pattern.
