An overview of contraception in women with obesity

The use of safe and effective contraception is essential for preventing unplanned pregnancy in women of all body sizes. When counseling women with obesity about contraception, it is important to consider the pharmacokinetic alterations of obesity on various modern contraceptive methods. However, evidence is reassuring that most contraceptive methods are safe and effective in women with obesity. Individual countries and the World Health Organization have published Medical Eligibility Criteria to guide contraceptive selection in women with medical issues including obesity. When choosing contraception, specific risks of the method relative to any underlying medical disorders must also be balanced against the risks of unintended pregnancy in this group.

Which Hormones and Contraception for Women with APS? Exogenous Hormone Use in Women with APS

PURPOSE OF REVIEW

Use of exogenous estrogen carries significant risk for patients with prothrombotic disorders including those with antiphospholipid antibody (aPL) and antiphospholipid syndrome (APS). This review summarizes current knowledge of contraceptive and other hormone therapies for aPL-positive and APS women and highlights knowledge gaps to guide future research.

RECENT FINDINGS

Studies support very low risk for most progestin-only contraceptives in patients with increased thrombotic risk, but suggest increased VTE risk with depot-medroxyprogesterone acetate. Highest efficacy contraceptives are intrauterine devices and subdermal implants, and these are recommended for women with aPL/APS. Progestin-only pills are effective and low risk. Perimenopausal symptoms may be treated with nonhormone therapies in aPL/APS patients: vasomotor symptoms can improve with nonhormonal medications and cognitive behavioral therapy, and genitourinary symptoms often improve with intravaginal estrogen that has limited systemic absorption.

Combined hormonal contraception and COVID-19

Aim: This article reviews the possibility of using combined hormonal contraception during the COVID-19 pandemic. Methods: narrative reviewResults: The factors that protect women from the severity of the disease are analysed, as well as the risk factors for the use of this type of contraception, especially related to the increased risk of a thrombotic event in patients affected by the disease. Finally, the information available on the guidelines for action in patients with COVID-19 using combined hormonal contraception is collected.Conclusions: We can continue to prescribe and use hormonal methods with EE.

Contraception in adolescents with anorexia nervosa. Is there evidence for a negative impact of combined hormonal contraceptives on bone mineral density and the course of the disease?

Objective: Adolescents with anorexia nervosa (AN) are at increased risk of unplanned pregnancies and bone loss, due to low oestrogen levels and low use of efficient contraception. The negative impact of combined hormonal contraceptives (CHC) on peak bone mass during adolescence might limit wider use in anorexic women. Another issue limiting CHC use is the concern, that CHC-induced cyclic bleeding reduces the motivation for further weight gain and thus exerts a negative impact on recovery. We wanted to find evidence based answers about the impact of CHC use on bone health and course of the disease in adolescents with AN.Methods: We performed a narrative review of the current literature investigating the effect of CHC or progestin-only contraceptives on bone density, body shape and course of disease in young women with anorexia.Results: There is no evidence that CHC use aggravates the bone loss associated with AN. In long-term users CHC exert a protective effect. Anorexic women using CHC showed at least the same or a greater weight gain in comparison with controls. Eating disorder attitudes did not worsen.Conclusion: We conclude, that at present there is no evidence, that use of CHC by AN patients has a negative impact on bone density or the course of disease.

[Hormonal contraception and vascular risk: CNGOF Contraception Guidelines]

Venous thromboembolism and arterial ischemic events are the main deleterious diseases associated with the use of combined hormonal contraceptives (CHC). Even though their composition has been substantially improved, the vascular risk persists with the most recent CHCs use. If the vascular risk associated with CHCs containing 50μg EE is significantly higher than with those containing less than 50μg, there is no evidence that the CHCs containing either 30 or 20μg of EE induce different venous risks. CHC containing gestodene, desogestrel, drospirenone or cyproterone acetate are associated with a higher risk of venous thrombosis compared with levonorgestrel-containing CHCs. CHC containing norgestimate are associated with similar venous thrombosis risk than CHC containing levonorgestrel. Venous thrombosis risk of non-oral routes of administration of CHC appears to be equivalent to the risk of CHC containing gestodene or desogestrel, but this result is based on a small number of epidemiological studies. Before prescribing a CHC, it is important to determine all vascular risk factors. Family history of ischemic arterial event or venous thromboembolism disease should be routinely sought before any CHC prescription. All CHCs are contraindicated in women with biological thrombophilia, in women with combined vascular risk factors, in women with first-degree family history of arterial or venous event (under age 50) as well as in women suffering of migraine with aura. Progestin-only contraceptives are not associated with vascular risk (arterial or venous) outside of medroxyprogesterone acetate. In women with higher vascular risk, progestin-only contraceptives (administered by oral, sous-cutaneous or intra-uterine routes) can be prescribed.

Pharmacologic Therapies in Women's Health: Contraception and Menopause Treatment

Female hormones play a significant role in the etiology and treatment of many women's health conditions. This article focuses on the common uses of hormonal therapy. When prescribing estrogen-containing regimens throughout the span of a woman's life, the risks are similar (ie, cardiovascular risk and venous thromboembolism), but the degree of risk varies significantly depending on a woman's particular set of risk factors and the details of the hormone regimen. In addition to estrogens and progestogens, this article also touches on the use of selective steroid receptor modulators in emergency contraception and in treatment of menopause symptoms.

Extended regimen combined oral contraception: A review of evolving concepts and acceptance by women and clinicians

Objectives: The clinical utility of extended regimen combined oral contraceptives (COCs) is increasingly being recognised. Our objective was to understand the attitudes of women and clinicians about the use of these regimens. We present the rationale for extended regimen COCs from a historical perspective, and trace their evolution and growing popularity in light of their clinical benefits. We conclude by offering potential strategies for counselling women about extended regimen COC options.

Methods: We conducted a MEDLINE search to identify and summarise studies of extended regimen COCs, focusing on attitudes of women and clinicians regarding efficacy, safety/tolerability and fewer scheduled bleeding episodes and other potential benefits.

Results: The body of contemporary literature on extended regimen COCs suggests that their contraceptive efficacy is comparable to that of conventional 28-day (i.e., 21/7) regimens. For women seeking contraception that allows infrequent scheduled bleeding episodes, particularly those who suffer from hormone withdrawal symptoms and cyclical symptoms (e.g., headache, mood changes, dysmenorrhoea, heavy menstrual bleeding), extended regimen COCs are an effective and safe option. Although satisfaction with extended regimen COCs in clinical trials is high, misperceptions about continuous hormone use may still limit the widespread acceptance of this approach.

Conclusions: Despite the widespread acceptance among clinicians of extended regimen COCs as an effective and safe contraceptive option, these regimens are underused, likely due to a lack of awareness about their availability and utility among women. Improved patient education and counselling regarding the safety and benefits of extended regimen COCs may help women make more informed contraceptive choices.

Combined hormonal contraceptive use among women with known dyslipidemias: a systematic review of critical safety outcomes

CONTEXT

Dyslipidemias represent a spectrum of lipid disorders that are important risk factors for cardiovascular disease. In addition, elevated triglycerides are known to be associated with pancreatitis. Though less clear, it is possible that dyslipidemias may also contribute to risk for venous thromboembolism (VTE). Ethinyl estradiol and progestogen, contained within combined hormonal contraception, are known to impact lipid metabolism.

OBJECTIVES

To evaluate from the literature whether use of combined hormonal contraception (CHC), including combined oral contraception (COC) pills, transdermal patch, vaginal ring or injectables, modifies the relative risk of acute myocardial infarction (MI), stroke, VTE or pancreatitis among women with known dyslipidemias and to determine if existing lipid abnormalities worsen with CHC use.

METHODS

PubMed and the Cochrane Library databases were searched for all articles in all languages published between inception and September 2014 relevant to dyslipidemia, CHC use and serious adverse events (MI, stroke, VTE or pancreatitis). The quality of each individual study was assessed using the system for grading evidence developed by the United States Preventive Services Task Force.

RESULTS

From 306 articles identified by our search strategy, 3 articles met inclusion criteria. In a poor-quality case-control study, women with hypercholesterolemia but no COC use had an increased risk of MI (adjusted odds ratio [adj OR] 3.3, 95% confidence interval [CI] 1.6-6.8), as did women who used COCs but did not have hypercholesterolemia (adj OR 2.0, 95% CI 1.4-2.8), compared with non-COC users without hypercholesterolemia; women with both COC use and hypercholesterolemia had an adjusted OR of 24.7 (95% CI 5.6-108.5) compared with women with neither risk factor. A poor-quality cohort study examined COC users and reported that women with dyslipidemia had increased risk for VTE [crude risk ratio (RR) 1.39, 95% CI 1.04-1.85] and transient ischemic attacks or cerebrovascular accidents (CVAs) (RR 1.76, 95% CI 1.51-2.06) compared to those without dyslipidemia. Another poor-quality cohort study provided direct evidence on changes in lipid levels among COC users with dyslipidemia. A minority of women with elevated total cholesterol or triglyceride levels at baseline showed normal results (25% and 28%, respectively) after 6 cycles of COC use. No evidence regarding risks associated with use of other CHC methods was identified. No evidence was identified for the outcome of pancreatitis.

CONCLUSION

Limited data from poor-quality observational studies suggest that women with known dyslipidemias using CHC may be at increased risk for MI and may experience a minimal increase in risk for CVA or VTE. No evidence was identified on risk for pancreatitis in this context. The impact of CHC exposure on the status of lipid abnormalities over time, an intermediate marker for disease, is also unclear. Given the significant limitations of this body of evidence, the importance of access to effective contraception and theoretical concerns raised about the use of CHCs by women with known dyslipidemias, additional rigorous studies are needed to best estimate true associations. Contraceptive decision making should include consideration of both the known and theoretical risks of a given CHC method, safety and acceptability of alternative contraceptive methods, and risks associated with unintended pregnancy.

Broad counseling for adolescents about combined hormonal contraceptive methods: the choice study

PURPOSE

The Contraceptive Health Research of Informed Choice Experience study involved 11 European countries with the goal of evaluating the influence of counseling on the user's choice among three different types of combined hormonal contraceptive (CHC) administration: pill, transdermal patch, and vaginal ring. Here, we report the results of the youngest age group (age 15-20 years) for Switzerland.

METHODS

A total of 1,032 adolescent women who contemplated a CHC form of contraception were counseled about the three CHCs. Questionnaires were filled out to determine the women's preferred choice before and after counseling, and the reason for their final decision.

RESULTS

After counseling, more than one third of the women decided to use a different contraceptive method than initially intended. The fraction of vaginal ring users increased from 7.5% to 21.8%, and that of patch users from 3.3% to 5.8%. At pre-counseling, 225 women had no preconceived idea about which method to choose. Only 29 women were still undecided post-counseling. The main reasons adolescent women chose the vaginal ring or the patch were the monthly or weekly use and the ease of use.

CONCLUSIONS

Adolescent women's decision about which CHC to use is greatly influenced by counseling that provides balanced information on all CHCs.

Classical and newly recognised non-contraceptive benefits of combined hormonal contraceptive use in women over 40

Although age is the most crucial predictor of a woman's reproductive capacity, it is assumed that there is still a risk of pregnancy in menopause transition, as occasional spontaneous ovulation is possible. Moreover, age alone is not sufficient to contraindicate the use of any contraceptive method, whether hormonal or not. The use of new CHC in women over 40 has not only been associated with an improved safety profile but has also been associated with other non-contraceptive benefits or the consolidation of already-known benefits. The studies with new CHC have demonstrated that efficacy and safety do not differ from the corresponding parameters observed in younger women. Additionally, the new CHC offers specific and especially useful benefits for women over 40 in the treatment of menstrual disorders. Finally, interest is currently focused on the potential of early diagnosis and the prevention of cardiovascular disease and depression, both of which may be alleviated by the CHC.
