RESUMO

INTRODUCTION: Breast cancer is the most common cancer in women worldwide and is a significant threat to public health. This study aims to conduct a systematic review of the relationship between hormonal contraceptive use and breast cancer incidence. METHODS: The search was conducted using Google Scholar, Proquest, Pubmed and one Indonesian database, Garuda, using English and Indonesian keywords. The inclusion criteria in this study were the publication year of the last five years, namely 2019-2023, English and Indonesian language, case-control observational research, using the Indonesian population, and full-text access. RESULTS: A total of 165 studies were obtained from the Google Scholar database, including 104 studies. The overall multivariate analysis revealed that there was a statistically significant association of hormonal contraception with the incidence of breast cancer with OR values in the range of 2-6. CONCLUSIONS: The findings of this systematic study suggest that the use of hormones can contribute to hormonal imbalances that further increase breast cell proliferation and disrupt gene expression, resulting in uncontrolled cell development/cancer. In addition, the findings recommend increasing the number of studies on this topic to obtain more adequate and possibly more diverse information.

RESUMO

Most sexually active women of reproductive age have used contraception, with hormonal methods constituting approximately 40% of contraceptive choices. Among these hormonal options, combined oral contraceptives stand out as the most selected. Within this same demographic, sexual issues are prevalent. Although specific hormonal contraceptives have been implicated in sexual dysfunction among these women, the correlation lacks consistency across studies and varies between different types of hormonal contraception. This article assesses the available literature on the associations between various hormonal contraceptive methods and sexual function and provides practical management insights.

RESUMO

This study aimed to explore how natural menstrual cycle phases and dosage of oral hormonal contraceptives (OC) influence the diurnal rhythm of distal skin temperature (DST) under real-life conditions. Participants were 41 healthy females (23.9 ± 2.48 y), comprising 27 females taking monophasic hormonal oral contraceptives (OC users) and 14 females with menstrual cycles (non-OC users). Wrist DST was continuously recorded and averaged over two consecutive 24-hour days during (pseudo)follicular and (pseudo)luteal menstrual phases. Diurnal rhythm characteristics, i.e. acrophase and amplitude, describing timing and strength of the DST rhythm, respectively, were calculated using cosinor analysis. Results show that non-OC users experienced earlier diurnal DST maximum (acrophase, p = 0.019) and larger amplitude (p = 0.016) during the luteal phase than during the follicular phase. This was observed in most (71.4%) but not all individuals. The OC users showed no differences in acrophase or amplitude between pseudoluteal and pseudofollicular phases. OC users taking a higher dosage of progestin displayed a larger amplitude for DST rhythm during the pseudoluteal phase (p = 0.009), while estrogen dosage had no effect. In conclusion, monophasic OC cause changes in diurnal DST rhythm, similar to those observed in the luteal phase of females with menstrual cycles, suggesting that synthetic progestins act in a similar manner on skin thermoregulation as progesterone does.

RESUMO

PURPOSE: To correlate the sexual desire levels with sexual hormone binding globulin and free androgen index in women taking different types of hormonal contraceptives (HCs) containing ethinylestradiol (EE), oestradiol valerate (E2V), 17ß-oestradiol (E2), or estetrol (E4), combined or in phasic formulation with different progestogens having antiandrogenic properties. METHODS: Three hundred and sixty-seven women (age range 18-46) participated in the study. SHBG and total testosterone (TT) were measured, and the Free Androgen Index (FAI) was calculated. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively. RESULTS: The highest SHBG values and the lowest FAIs were obtained of women on HCs containing EE than those of women on HCs containing E2V/17ß E2 or E4 (p < 0.001). Desire scores and FSFI total scores were lower in women on HCs with EE than in those using HCs containing E2V, 17ß E2, or E4 (p ≤ 0.001). The women who were on HCs containing EE reported FSDS levels higher than those containing all the other types of oestrogen. Finally, sexual desire and FSFI total scores had a negative correlation with the SHBG values and a positive correlation with FAI percentage (p ≤ 0.0001). CONCLUSIONS: A minority of women using HCs with EE might experience a decreased sexual desire. This was not observed in women on HCs containing E2V, 17 E2, or E4. To avoid HC discontinuation, due to sexual desire reduction, HCs having minor antiandrogenic effects could be taken into consideration.

RESUMO

Previous research on the endogenous effects of ovarian hormones on motivational states in women has focused on sexual motivation. The Motivational Priority Shifts Hypothesis has a broader scope. It predicts a shift from somatic to reproductive motivation when fertile. In a highly powered preregistered online diary study across 40 days, we tested whether 390 women report such an ovulatory shift in sexual and eating motivation and behaviour. We compared 209 naturally cycling women to 181 women taking hormonal contraceptives (HC) to rule out non-ovulatory changes across the cycle as confounders. We found robust ovulatory decreases in food intake and increases in general sexual desire, in-pair sexual desire and initiation of dyadic sexual behaviour. Extra-pair sexual desire increased mid-cycle, but the effect did not differ significantly in HC women, questioning an ovulatory effect. Descriptively, solitary sexual desire and behaviour, dyadic sexual behaviour, appetite, and satiety showed expected mid-cycle changes that were diminished in HC women, but these failed to reach our strict preregistered significance level. Our results provide insight into current theoretical debates about ovulatory cycle shifts while calling for future research to determine motivational mechanisms behind ovulatory changes in food intake and considering romantic partners' motivational states to explain the occurrence of dyadic sexual behaviour.

RESUMO

Hormonal contraceptives are widely prescribed due to their effectiveness and convenience and have become an integral part of family planning strategies worldwide. In the United States, approximately 65% of reproductive-aged women are estimated to be using contraceptive options, with approximately 33% using one or a combination of hormonal contraceptives. While these methods have undeniably contributed to improved reproductive health, recent studies have raised concerns regarding their potential effect on metabolic health. Despite widespread anecdotal reports, epidemiological research has been mixed as to whether hormonal contraceptives contribute to metabolic health effects. As such, the goals of this study were to assess the adipogenic activity of common hormonal contraceptive chemicals and their mixtures. Five different models of adipogenesis were used to provide a rigorous assessment of metabolism-disrupting effects. Interestingly, every individual contraceptive (both estrogens and progestins) and each mixture promoted significant adipogenesis (eg, triglyceride accumulation and/or preadipocyte proliferation). These effects appeared to be mediated in part through estrogen receptor signaling, particularly for the contraceptive mixtures, as cotreatment with fulvestrant acted to inhibit contraceptive-mediated proadipogenic effects on triglyceride accumulation. In conclusion, this research provides valuable insights into the complex interactions between hormonal contraceptives and adipocyte development. The results suggest that both progestins and estrogens within these contraceptives can influence adipogenesis, and the specific effects may vary based on the receptor disruption profiles. Further research is warranted to establish translation of these findings to in vivo models and to further assess causal mechanisms underlying these effects.

RESUMO

BACKGROUND AND OBJECTIVE: Abrocitinib is an oral small-molecule Janus kinase (JAK)-1 inhibitor approved for the treatment of moderate-to-severe atopic dermatitis. In vitro studies indicated that abrocitinib is a weak time-dependent inhibitor of cytochrome P450 (CYP) 2C19/3A and a weak inducer of CYP1A2/2B6/2C19/3A. To assess the potential effect of abrocitinib on concomitant medications, drug-drug interaction (DDI) studies were conducted for abrocitinib with sensitive probe substrates of these CYP enzymes. The impact of abrocitinib on hormonal oral contraceptives (ethinyl estradiol and levonorgestrel), as substrates of CYP3A and important concomitant medications for female patients, was also evaluated. METHODS: Three Phase 1 DDI studies were performed to assess the impact of abrocitinib 200 mg once daily (QD) on the probe substrates of: (1) 1A2 (caffeine), 2B6 (efavirenz) and 2C19 (omeprazole) in a cocktail study; (2) 3A (midazolam); and (3) 3A (oral contraceptives). RESULTS: After multiple doses of abrocitinib 200 mg QD, there is a lack of effect on the pharmacokinetics of midazolam, efavirenz and contraceptives. Abrocitinib increased the area under the concentration time curve from 0 to infinity (AUCinf) and the maximum concentration (Cmax) of omeprazole by approximately 189 and 134%, respectively. Abrocitinib increased the AUCinf of caffeine by 40% with lack of effect on Cmax. CONCLUSIONS: Based on the study results, abrocitinib is a moderate inhibitor of CYP2C19. Caution should be exercised when using abrocitinib concomitantly with narrow therapeutic index medicines that are primarily metabolized by CYP2C19 enzyme. Abrocitinib is a mild inhibitor of CYP1A2; however, the impact is not clinically relevant, and no general dose adjustment is recommended for CYP1A2 substrates. Abrocitinib does not inhibit CYP3A or induce CYP1A2/2B6/2C19/3A and does not affect the pharmacokinetics of contraceptives.

RESUMO

Short-acting reversible contraceptives (SARCs) are prescribed routinely by primary care clinicians. SARCs are among the most commonly prescribed contraceptive methods and include combined hormonal oral contraceptive pills, the combined hormonal transdermal patch, the combined hormonal vaginal ring, progestin-only pills, and the 3-month depot medroxyprogesterone acetate injection. To ensure safe prescribing and reduce barriers to receiving SARC methods, family physicians should be familiar with two evidence-based national contraceptive guidelines, the U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) and the U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR). SARCs have benefits in addition to pregnancy prevention; as such, these methods may be chosen for reasons other than contraception.

RESUMO

OBJECTIVES: To investigate the oral manifestations in women of reproductive age using hormonal contraceptive methods. MATERIALS AND METHODS: This review is based on the PRISMA statement. A literature search incorporated observational studies from the last 21 years. An investigative question was formulated using the PICO model, studies were selected, and a quality analysis was performed using the modified STROBE guidelines. A bibliometric analysis was performed, and the data were examined. RESULTS: Thirteen articles were included, with the majority evaluating periodontal status. Others analyzed factors such as the presence of alveolar osteitis, oral candidiasis, and salivary microbiome dysbiosis. Ten articles were deemed to have a low risk of bias. CONCLUSIONS: Hormonal contraceptives may increase the risk of alveolar osteitis following tooth extraction and increase the presence of the Candida species in the oral cavity. They also affect the periodontium, such as the frequent development of gingivitis, but do not lead to changes in the salivary microbiome. CLINICAL RELEVANCE: The increasing number of women using hormonal contraceptives and the knowledge that these contraceptives can produce oral cavity alterations underscore the need to evaluate the oral manifestations found in these women.

RESUMO

BACKGROUND: Despite conflicting findings in the current literature regarding the correlation between contraceptives and maternal health consequences, statistical analyses indicate that family planning may decrease the occurrence of such outcomes. Consequently, it is crucial to assess the capability of family planning to mitigate adverse maternal health outcomes. OBJECTIVES: This review investigates the effects of modern contraceptive use on maternal health. SEARCH METHODS: This systematic review is registered on Prospero (CRD42022332783). We searched numerous databases with an upper date limit of February 2022 and no geographical boundaries. SELECTION CRITERIA: We included observational studies, including cross-sectional, cohort, case-control studies, and non-RCT with a comparison group. We excluded systematic reviews, scoping reviews, narrative reviews, and meta-analyses from the body of this review. MAIN RESULTS: The review included nineteen studies, with five studies reporting a reduction in maternal mortality linked to increased access to family planning resources and contraceptive use. Another three studies examined the impact of contraception on the risk of preeclampsia and our analysis found that preeclampsia risk was lower by approximately 6% among contraceptive users (95% CI 0.82-1.13) compared to non-users. Two studies assessed the effect of hormonal contraceptives on postpartum glucose tolerance and found that low-androgen contraception was associated with a reduced risk of gestational diabetes (OR 0.84, 95% CI 0.58-1.22), while DMPA injection was possibly linked to a higher risk of falling glucose status postpartum (OR 1.42, 95% CI 0.85-2.36). Two studies evaluated high-risk pregnancies and births in contraceptive users versus non-users, with the risk ratio being 30% lower among contraceptive users of any form (95% CI 0.61, 0.80). None of these results were statistically significant except the latter. In terms of adverse maternal health outcomes, certain contraceptives were found to be associated with ectopic pregnancy and pregnancy-related venous thromboembolism through additional analysis.

RESUMO

Abnormal uterine bleeding is a common and bothersome symptom in people using hormonal contraception, and it can lead to discontinuation of reliable methods of contraception and unintended pregnancies. Clinicians should counsel individuals about the potential for abnormal bleeding at initiation of the contraceptive method. After considering and excluding other potential causes of abnormal uterine bleeding, clinicians can offer treatment options specific to each hormonal contraceptive method. This article includes algorithms to help clinicians treat abnormal uterine bleeding in people using levonorgestrel intrauterine devices, depo-medroxyprogesterone acetate, progestin implant, progestin-only pills, and combined hormonal contraception. For patients with levonorgestrel intrauterine devices, physicians should first ensure that the device is correctly placed within the uterus, then consider nonsteroidal anti-inflammatory drugs as a first-line treatment for abnormal uterine bleeding; estradiol can be used if nonsteroidal anti-inflammatory drugs are ineffective. For depo-medroxyprogesterone acetate or progestin implant users, combined oral contraceptives or nonsteroidal anti-inflammatory drugs may be considered. For patients using norethindrone progestin-only pills, changing to drospirenone progesterone-only pills may help reduce the bleeding. In people using combined hormonal contraception, it may be helpful to increase estrogen content from 20 mcg to 35 mcg per day, decrease the hormone-free interval (from seven to four or five days) in people using cyclic contraception, or start a trial of low-dose doxycycline. For continuous combined contraception users, adding a hormone-free interval of four or five days can help regulate bleeding patterns.

RESUMO

PURPOSE OF REVIEW: This review presents the epidemiology of mental health conditions among reproductive aged people, common adverse reproductive outcomes, the hormonal profile of contraception and its relationship with psychiatric outcomes, and updated information for clinicians providing contraceptive counselling for this population. RECENT FINDINGS: There is variability among contraceptive behaviours and patterns across those who have mental health conditions, impacting reproductive, psychiatric, and perinatal outcomes. The endocrinology of hormonal contraceptives is well understood, however, the impacts of steroidal hormones on mental health outcomes continue to be less understood. Overall, hormonal contraceptives are safe to use among those with mental health conditions, and among those using selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors. Additional considerations are needed when prescribing contraception among people who may be at risk of poor adherence, who use certain classes of antidepressants, antipsychotics, antiepileptics, and who are <6 weeks postpartum. SUMMARY: Barriers to effective contraceptive use should be addressed and myths on negative psychiatric impacts of hormonal contraceptives should be dispelled. Healthcare clinicians should seek out opportunities to become proficient in contraception counselling to improve health outcomes among people with mental health conditions.

RESUMO

BACKGROUND: The main drawback of oral contraceptives (OC) and hormone replacement therapy (HRT) is an increased risk of venous and, to a lesser extent, arterial thrombosis. MATERIALS AND METHODS: This narrative, case-based review describes the effect of available estrogens and progestogens on the hemostatic system and their potential impact on the risk of thrombosis. Clinical cases are used to illustrate different options for prescribing OC and HRT in the real-word. The aim is to offer discussion topics that could be helpful to guide the choice of different hormonal treatments over a woman's lifetime and in the presence of risk factors. RESULTS: We describe physio-pathological changes occurring during the administration of hormonal therapies. Furthermore, we analyze the risk of venous and arterial thrombosis associated with different products, routes of administration and additional risk factors. New hormonal preparations, such as estradiol combined with dienogest, as well as non-oral hormonal therapies, are suggested to decrease thrombotic risk significantly. DISCUSSION: The availability of many products and different routes of administration allow most women to safely use contraception, as well as HRT. We encourage careful counselling instead of inflexible or fearful behavior, as expanding options and choices will allow women to make the best decisions for their health.

RESUMO

Changes in kynurenine metabolites are reported in users of estrogen containing contraception. We have assessed kynurenines, vitamin B6, vitamin B2 and the inflammation markers, C-reactive protein (CRP) and neopterin, in healthy, never-pregnant women between 18 and 40 years (n = 123) and related this to their use of hormonal contraception. The population included 58 women, who did not use hormonal contraceptives (non-users), 51 users of estrogen-containing contraceptives (EC-users), and 14 users of progestin only contraceptives (PC-users). EC-users had significantly lower plasma kynurenic acid (KA) and higher xanthurenic acid (XA) levels compared to non-users. Serum CRP was significantly higher and negatively associated with both vitamin B6 and B2 status in EC-user compared to non-users. No significant differences in any parameters were seen between PC-users and non-users (p > 0.1). The low KA and high XA concentration in users of estrogen containing contraception resemble the biochemical profile observed in vitamin B6 deficiency. The hormonal effect may result from interference with the coenzyme function of vitamin B6 and B2 for particular enzymes in the kynurenine metabolism. KA has been suggested to be neuroprotective and the significantly reduced concentration in EC-users may be of importance in the observed increased risk of mood disorders among users of oral contraceptives.

RESUMO

OBJECTIVES: This study aimed to compare contraceptive efficacy and safety of drospirenone 4 mg in a 24/4-day regimen in nonobese and obese users and describe pharmacokinetics according to bodyweight. STUDY DESIGN: We analyzed data from three drospirenone 4 mg trials (2 European and 1 United States) to report outcomes in nonobese (body mass index <30 kg/m2) and obese (body mass index ≥30 kg/m2) users. We used data from the US trial to calculate the Pearl Index (pregnancies per 100 woman-years) in nonbreastfeeding participants aged ≤35 years at enrollment for confirmed pregnancies. We assessed safety outcomes from all trials based on reported treatment-emergent adverse events. We evaluated pharmacokinetics by bodyweight in the US trial. RESULTS: The three trials combined comprised 2152 nonobese and 425 obese participants, including 590 nonobese and 325 obese participants in the US trial. Eight nonobese and four obese participants had confirmed pregnancies in the US trial, resulting in Pearl Indices of 3.0 (95% CI: 1.3-5.8) and 2.9 (95% CI: 0.8-7.3), respectively. Two-hundred forty-four (11.3%) nonobese and 39 (9.2%) obese participants discontinued due to a treatment-emergent adverse event. The pharmacokinetic analysis included 814 participants with a median weight of 73 (interquartile range 61-89) kg and median plasma drospirenone exposure (AUC0-24ss) of 661.3 (interquartile range 522-828) ng∙h/mL. Changing bodyweight from the median to the fifth percentile (51 kg) or 95th percentile (118 kg) changed drospirenone exposure (AUC0-24,ss) by 22.2% and -23.6%, respectively. CONCLUSIONS: Drospirenone 4 mg demonstrated similar contraceptive efficacy for both nonobese and obese users despite a difference in exposure based on bodyweight. IMPLICATIONS: Our limited comparison between obese and nonobese users of drospirenone-only oral contraception demonstrated no evidence that efficacy or discontinuation for adverse events differs between groups. Serum drospirenone levels vary by bodyweight and may correlate with bleeding outcomes.

RESUMO

Patients with sickle cell disease (SCD) are at a risk of thromboembolism (TE), and use of hormonal contraception can further increase that risk. This study aims to assess patterns of hormonal contraceptive use and compare risk of contraception-related TE between combined hormonal contraceptives (CHCs) and progestin-only contraceptives (POCs). Patients with SCD aged between 12 and 44 years with a new prescription of a hormonal contraceptive in the Centers for Medicare and Medicaid Services Medicaid Analytic eXtract database (2006-2018) were followed up to 1 year. We identified 7173 new users: 44.6% initiated CHC and 55.4% initiated POC. Combined oral contraceptive pills (OCPs; 36.5%) and progestin-only depot medroxyprogesterone acetate (33.9%) were the most frequently prescribed agents. A total of 1.8% of contraception users had a new diagnosis of TE within 1 year of the first identified contraception prescription. There were no significant differences in TE event rates between CHC and POC users (17.2 and 24.7 events per 1000 person-years, respectively). In patients prescribed OCP, there were no differences in TE event rates based on estrogen dose or progestin generation. Transdermal patch had a 2.4-fold increased risk of TE as compared with that of OCP. Although limited by the retrospective study design and use of administrative claims data, this study found no significant differences in TE rates between new users of CHC and POC in patients with SCD. Careful evaluation of underlying TE risk factors should be considered for each patient with SCD before initiation of hormonal contraception.
