Contraception for Women with Chronic Medical Conditions

Depo-Provera (depot medroxyprogesterone acetate) use after bariatric surgery

In the US, obesity rates are increasing greatly. The Centers for Disease Control and Prevention estimates that 68.5% of Americans, including 63.9% of adult women older than 20 years, are overweight (body mass index between 25 kg/m² and 29.9 kg/m²) or obese (body mass index >30 kg/m²). In light of this, it is not surprising that the rates of bariatric surgery have also been increasing. When considering the metabolic changes associated with both bariatric surgery and contraceptive use, in combination with the unique medical considerations of obese women, it is indisputable that clear guidelines are needed when counseling obese patients of reproductive age after bariatric surgery. In this literature review, we focus on depot medroxyprogesterone acetate (DMPA) and the implications of its use in obese women, preweight and postweight loss following bariatric surgery. Both DMPA use and bariatric surgery are known to cause bone loss, but it is still unclear whether there is an additive effect of the two factors on bone loss and whether either of these factors directly leads to an increased risk of bone fracture. The current consensus guidelines do not impose a restriction on the use of DMPA after bariatric surgery. DMPA use is associated with weight gain, and it is unclear whether weight loss blunting occurs with the use of DMPA after bariatric surgery. Prior studies had demonstrated an association with weight gain in adolescents, and therefore, those prescribing DMPA use after bariatric surgery in adolescents should proceed with caution. Adult women do not have a similar response to the use of DMPA. DMPA use has rarely been associated with increased risk of venous thromboembolism (VTE). The obesity-associated increase in VTE should be mitigated by surgically induced weight loss. The concurrent use of DMPA in the post bariatric surgical period should not further increase the risk of VTE.

Side effects unrelated to disease activity and acceptability of highly effective contraceptive methods in women with systemic lupus erythematosus: a randomized, clinical trial

OBJECTIVES

To assess the side effects unrelated to disease activity and the acceptability of combined oral contraceptives (COCs), progestin-only pills (POPs) and copper-releasing intrauterine devices (IUDs) in women with systemic lupus erythematosus (SLE).

STUDY DESIGN

A randomized clinical trial including 162 women with SLE, assigned to COC (n=54), POP (n=54) or IUD (n=54). Follow-up visits were conducted after 1, 2, 3, 6, 9 and 12 months of treatment to monitor the presence of symptoms, changes in body weight and blood pressure as well as the development of health problems other than those relating to lupus. Reasons for discontinuation and satisfaction with the use of the assigned method were recorded at the end of treatment. Statistical analysis included descriptive statistics, repeated measure analyses and Kaplan-Meier curves.

RESULTS

Significantly different discontinuation rates due to any reason [35%, 55%, 29% (p<0.01)] or nonmedical reasons [(11%, 31%, 4% (p<0.05)] were observed among the COC, POP and IUD groups. Nausea was most frequent among COC users, dysmenorrhea among IUD users and acne and hirsutism among POP users. Mean blood pressures remained unchanged. Mild increases in body weight were observed over time in all treatment groups. Most women were satisfied with the use of the assigned contraceptive method.

CONCLUSIONS

Oral contraceptives and IUD are acceptable birth control methods for patients with lupus, when counseling and specialized health attention are provided; however, the acceptability of POP appears to be inferior. Side effects unrelated to lupus disease activity are not frequent reasons to discontinue the contraceptive methods.

IMPLICATIONS

This study delves into an area that has not been explored among patients with lupus. Our findings on the associated side effects and reasons for discontinuing COCs, POPs or copper-bearing IUDs may be useful in improving contraceptive counseling for women with lupus. Furthermore, they also heighten our knowledge on the reasons that may preclude the widespread use of effective contraceptives among lupus patients.

Reproductive and contraceptive issues in chronically ill adolescents

OBJECTIVES

To address reproductive and contraceptive issues in adolescent girls with chronic medical conditions in order to assist health-care providers when they counsel teenagers about contraceptive methods.

METHODS

The review is based on a literature search in Medline (1973-2010) about specific contraceptive use by adolescents with obesity, endocrine, cardiovascular, haematologic, oncologic, neurological, psychiatric, gastrointestinal, hepatobiliary, autoimmune, renal, pulmonary conditions and disabilities. The latest recommendations from the World Health Organisation for adolescents are also added. Contraceptive methods studied were combined hormonal contraceptives, progestogen-only contraceptives, and intrauterine contraceptives.

RESULTS

Adolescents are eligible to use any method of contraception. Contraceptive choices of chronically ill adolescents have changed over time. Given new developments in the field of adolescent sexual and reproductive health care, safe and effective forms of contraception are available for almost every adolescent with a chronic condition. When selecting a method, the nature of the medical illness and the expressed desires of the teenager must be taken into account.

CONCLUSIONS

Adolescents, including those with chronic conditions, are sexual beings; they are entitled to sexual and reproductive health care. Decisions on appropriate contraception must be based upon informed choice, after adequate sexual health education.

Fertility choices and management for HIV-positive women

PURPOSE OF REVIEW

It is becoming increasingly important to address the issue of reproductive counselling and management of HIV-infected individuals during their reproductive years. Sexual and reproductive health-related needs and aspirations are similar to those of uninfected individuals but some differences require specific attention, which are discussed in this review.

RECENT FINDINGS

Hormonal contraception should be used with caution in women on antiretroviral treatment. Its impact on both HIV infectivity and disease progression is still controversial. An intrauterine device can be considered for pregnancy prevention and pregnancy termination should be offered in safe conditions. HIV-infected women have a lower spontaneous fertility rate, which may persist after assisted reproduction. Data on safety of antiretroviral treatment during conception are reassuring. No clear association can be found between exposure to antiretrovirals and fetal abnormalities. Secondary prevention remains crucial and condom use remains a key method.

SUMMARY

Different topics related to fertility choices among HIV-infected patients should be addressed. Family planning methods and termination of pregnancy have specific aspects among infected individuals. When needed, medically assisted reproduction may be required and antiretroviral treatment should be adapted before conception. Secondary prevention has a key role in reducing newly acquired infections.

Concepts of contraception for adolescent and young adult women with chronic illness and disability

Sexual behavior is common in adolescents and young adults with or without chronic illness or disability, resulting in high levels of unplanned pregnancy and STDs. Individuals with chronic illness or disability should not receive suboptimal preventive health care. These individuals have a need for counseling regarding issues of sexuality and contraception. Sexually active adolescent and young adult women can be offered safe and effective contraception if they wish to avoid pregnancy. Women with chronic illnesses and disabilities who are sexually active should also be offered contraception based on their specific medical issues. Condoms are also recommended to reduce STD risks. Table 36 summarizes basic principles of contraception application for specific illnesses, which have been identified since the release of the combined OC in 1960. Clinicians should also consider the noncontraceptive benefits of this remarkable and life-changing technology that allows all reproductive age women to improve their lives, including those with chronic illnesses and disabilities.

HIV infection and contraception

HIV infection primarily affects women of childbearing age worldwide, in both developed and developing countries. With the advent of effective antiretroviral treatment, women are living longer and healthier lives, and the opportunity to have a child with minimal fear of vertical transmission is now a reality. For HIV-infected women, contraception and reproductive planning have become essential. Limited information is available on the variety of contraceptive options for HIV-infected women. It is important for all health care practitioners to educate themselves on contraceptive options so that they can provide optimal reproductive care to their HIV-infected female patients.

Gestational diabetes: risks, management, and treatment options

Gestational diabetes mellitus (GDM) is commonly defined as glucose intolerance first recognized during pregnancy. Diagnostic criteria for GDM have changed over the decades, and several definitions are currently used; recent recommendations may increase the prevalence of GDM to as high as one of five pregnancies. Perinatal complications associated with GDM include hypertensive disorders, preterm delivery, shoulder dystocia, stillbirths, clinical neonatal hypoglycemia, hyperbilirubinemia, and cesarean deliveries. Postpartum complications include obesity and impaired glucose tolerance in the offspring and diabetes and cardiovascular disease in the mothers. Management strategies increasingly emphasize optimal management of fetal growth and weight. Monitoring of glucose, fetal stress, and fetal weight through ultrasound combined with maternal weight management, medical nutritional therapy, physical activity, and pharmacotherapy can decrease comorbidities associated with GDM. Consensus is lacking on ideal glucose targets, degree of caloric restriction and content, algorithms for pharmacotherapy, and in particular, the use of oral medications and insulin analogs in lieu of human insulin. Postpartum glucose screening and initiation of healthy lifestyle behaviors, including exercise, adequate fruit and vegetable intake, breastfeeding, and contraception, are encouraged to decrease rates of future glucose intolerance in mothers and offspring.

The International Society for Bipolar Disorders (ISBD) consensus guidelines for the safety monitoring of bipolar disorder treatments

OBJECTIVES

Safety monitoring is an important aspect of bipolar disorder treatment, as mood-stabilising medications have potentially serious side effects, some of which may also aggravate existing medical comorbidities. This paper sets out the International Society for Bipolar Disorders (ISBD) guidelines for the safety monitoring of widely used agents in the treatment of bipolar disorder. These guidelines aim to provide recommendations that take into consideration the balance between safety and cost-effectiveness, to highlight iatrogenic and preventive clinical issues, and to facilitate the broad implementation of therapeutic safety monitoring as a standard component of treatment for bipolar disorder.

METHODS

These guidelines were developed by an ISBD workgroup, headed by the senior author (MB), through an iterative process of serial consensus-based revisions. After this, feedback from a multidisciplinary group of health professionals on the applicability of these guidelines was sought to develop the final recommendations.

RESULTS

General safety monitoring recommendations for all bipolar disorder patients receiving treatment and specific monitoring recommendations for individual agents are outlined.

CONCLUSIONS

These guidelines are derived from evolving and often indirect data, with minimal empirical cost-effectiveness data available to provide guidance. These guidelines will therefore need to be modified to adapt to different clinical settings and health resources. Clinical acumen and vigilance remain critical ingredients for safe treatment practice.

Effects of switching from oral to transdermal or transvaginal contraception on markers of thrombosis

BACKGROUND

The study was conducted to determine the impact of switching from oral to transdermal patch or vaginal ring contraception on biomarkers of thrombosis.

STUDY DESIGN

Current healthy oral contraceptive (OC) users were randomized to switch to either a contraceptive ring (CR) or patch (CP) and underwent phlebotomy to measure surrogate biomarkers of thrombosis [sex hormone-binding globulin (SHBG), free protein S and activated protein C resistance (APC-r)] before switching, and during the fourth cycle of use of the new method.

RESULTS

Of 142 reproductive age women enrolled, 120 sample pairs were available for analysis. SHBG increased significantly from baseline in CP users [mean change (95% CI), +29.9 nM (9.6-50)] but not in CR users [-1.6 (-16.6 to 13.5)]. Protein S decreased significantly from baseline in CP users [mean change -7.1% (-12.1 to -2.1)], but increased significantly in CR users [+5.3% (1.1-9.6)]. The APC-r ratio did not undergo a significant change from baseline in either group [CP +0.06 (-0.06 to 0.18), CR +0.02 (-0.10 to 0.14)]. Compared to CR users, subjects using the CP had significantly higher SHBG [187.5 (167.0-208), 146 (132.6-159.4), p=.012], significantly lower protein S [81.8 (76.8-86.8), 93.6 (89.1-98.1), p=.001] and similar APC-r ratios [2.99 (2.85-3.14), 3.09 (2.96, 3.22), p=.3] at the Cycle 4 visit.

CONCLUSION

OC users who switch to the ring exhibit beneficial changes in biomarkers of thrombosis, while those switching to the patch display a shift favoring clot formation.

Increased expression of the adult stem cell marker Musashi-1 in endometriosis and endometrial carcinoma

Adult stem cells are thought to be responsible for the high regenerative capacity of the human endometrium, and have been implicated in the pathology of endometriosis and endometrial carcinoma. The RNA-binding protein Musashi-1 is associated with maintenance and asymmetric cell division of neural and epithelial progenitor cells. We investigated expression and localization of Musashi-1 in endometrial, endometriotic and endometrial carcinoma tissue specimens of 46 patients. qPCR revealed significantly increased Musashi-1 mRNA expression in the endometrium compared to the myometrium. Musashi-1 protein expression presented as nuclear or cytoplasmic immunohistochemical staining of single cells in endometrial glands, and of single cells and cell groups in the endometrial stroma. Immunofluorescence microscopy revealed colocalization of Musashi-1 with its molecular target Notch-1 and telomerase. In proliferative endometrium, the proportion of Musashi-1-positive cells in the basalis layer was significantly increased 1.5-fold in the stroma, and three-fold in endometrial glands compared to the functionalis. The number of Musashi-1 expressing cell groups was significantly increased (four-fold) in proliferative compared to secretory endometrium. Musashi-1 expressing stromal cell and cell group numbers were significantly increased (five-fold) in both endometriotic and endometrial carcinoma tissue compared to secretory endometrium. A weak to moderate, diffuse cytoplasmic glandular staining was observed in 50% of the endometriosis cases and in 75% of the endometrioid carcinomas compared to complete absence in normal endometrial samples. Our results emphasize the role of Musashi-1-expressing endometrial progenitor cells in proliferating endometrium, endometriosis and endometrioid uterine carcinoma, and support the concept of a stem cell origin of endometriosis and endometrial carcinoma.
