Predictors of higher bone mineral density loss and use of depot medroxyprogesterone acetate

Changes in calcium metabolism and bone mineral density in new users of medroxyprogesterone acetate during the first year of use

OBJECTIVE

To evaluate calcium metabolism and bone mineral density (BMD) in new users of depot medroxyprogesterone acetate (DMPA) in the first year of use.

METHODS

This prospective, non-randomized study, conducted at the University of Campinas, São Paulo, Brazil, was carried out between February 2011 and February 2013. Women aged from 18 to 40 with a body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) <30 and with no known history of disease or medication use who chose to use DMPA were paired by age (±1 year) and BMI (±1) with women commencing the use of a copper intrauterine device (IUD). The primary outcomes were BMD measured by dual-energy X-ray absorptiometry and calcium metabolism markers; other variables were body composition and lifestyle habits. Repeated measures analysis of variance (ANOVA) and multiple regression analyses were used to evaluate associations.

RESULTS

Twenty-seven women using DMPA and 24 using IUD were evaluated, with a mean age of 29.7 years and 28.6 years, respectively. The DMPA group presented with a 3.6% (P<0.001) loss of lumbar spine BMD, a 2.1% (P=0.100) loss of femoral neck BMD and higher phosphorus (P=0.014) concentrations at 12 months compared to the IUD group. The decreases in BMD were associated with the use of DMPA, while total mass and coffee intake were found to be protective factors.

CONCLUSION

Changes in calcium metabolism and a decrease in BMD were found in the DMPA group at 12 months.

Dienogest 2 mg Daily in the Treatment of Adolescents with Clinically Suspected Endometriosis: The VISanne Study to Assess Safety in ADOlescents

STUDY OBJECTIVE

To study the safety and efficacy of dienogest 2 mg in adolescents with suspected endometriosis.

DESIGN

A 52-week, open-label, single-arm study.

SETTING

In 21 study centers, in 6 European countries.

PARTICIPANTS

Adolescents aged 12 to younger than 18 years with clinically suspected or laparoscopically confirmed endometriosis.

INTERVENTIONS

Dienogest 2 mg once daily.

MAIN OUTCOME MEASURES

The primary end point was relative change in lumbar spine (L2-L4) bone mineral density (BMD) measured using dual-energy x-ray absorptiometry. A key secondary end point was change in endometriosis-associated pain assessed using a visual analogue scale.

RESULTS

Of 120 patients screened, 111 comprised the full-analysis set (ie, patients who took ≥1 dose of study drug and had ≥1 post-treatment observation) and 97 (87.4%) completed the study. Mean lumbar BMD at baseline was 1.1046 (SD, 0.1550) g/cm². At the end of dienogest treatment (EOT; defined as at 52 weeks or premature study discontinuation), mean relative change in BMD from baseline was -1.2% (SD, 2.3%; n = 103). Follow-up measurement 6 months after EOT in the subgroup with decreased BMD at EOT (n = 60) showed partial recovery in lumbar BMD (mean change from baseline: -2.3% at EOT, -0.6% 6 months after EOT). Mean endometriosis-associated pain score was 64.3 (SD, 19.1) mm at baseline and decreased to 9.0 (SD, 13.9) mm by week 48.

CONCLUSION

In adolescents with suspected endometriosis, dienogest 2 mg for 52 weeks was associated with a decrease in lumbar BMD, followed by partial recovery after treatment discontinuation. Endometriosis-associated pain was substantially reduced during treatment. Because bone accretion is critical during adolescence, results of the VISanne study to assess safety in ADOlescents (VISADO) study highlights the need for tailored treatment in this population, taking into account the expected efficacy on endometriosis-associated pain and an individual's risk factors for osteoporosis.

Sexuality and Disability in Adolescents

Healthy sexual development is important for adolescents with and without disabilities, yet the topic of sexuality is often ignored in the disabled population. Adolescents with mild or moderate degrees of disability have rates of sexual activity and reproductive health needs comparable to their typically developing peers. Their need for support, risk reduction, and education in sexual health may exceed that of their peers. The medical provider may support healthy sexual development through education, anticipatory guidance, menstrual and contraceptive management, and by expanding the notion of sexuality to include a broader conceptualization of sexual behavior and expression.

Canadian Contraception Consensus (Part 3 of 4): Chapter 8 - Progestin-Only Contraception

OBJECTIVE

To provide guidelines for health care providers on the use of contraceptive methods to prevent pregnancy and on the promotion of healthy sexuality.

OUTCOMES

Overall efficacy of cited contraceptive methods, assessing reduction in pregnancy rate, safety, ease of use, and side effects; the effect of cited contraceptive methods on sexual health and general well-being; and the relative cost and availability of cited contraceptive methods in Canada.

EVIDENCE

Published literature was retrieved through searches of Medline and The Cochrane Database from January 1994 to January 2015 using appropriate controlled vocabulary (e.g., contraception, sexuality, sexual health) and key words (e.g., contraception, family planning, hormonal contraception, emergency contraception). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English from January 1994 to January 2015. Searches were updated on a regular basis in incorporated in the guideline to June 2015. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALUES

The quality of the evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). CHAPTER 8: PROGESTIN-ONLY CONTRACEPTION: Summary Statements Recommendations.

Factors associated with bone mineral density in healthy African women

There is a paucity of normative bone mineral density (BMD) data in healthy African women. Baseline total hip and lumbar spine BMD was measured in premenopausal women. BMD distribution was comparable to that of a reference population and was impacted by several factors including contraception and duration of lactation.

INTRODUCTION

Normative data on bone mineral density (BMD) and the cumulative impact of lactation, contraceptive use, and other factors on BMD in healthy African women have not been well studied.

OBJECTIVES

The objective of this study was to determine the factors associated with BMD in healthy premenopausal women in Uganda and Zimbabwe.

METHODS

Baseline total hip (TH) and lumbar spine (LS) BMD was measured by dual x-ray absorptiometry in 518 healthy, premenopausal black women enrolling in VOICE, an HIV-1 chemoprevention trial, at sites in Uganda and Zimbabwe. Contraceptive and lactation histories, physical activity assessment, calcium intake, and serum vitamin D levels were assessed. Independent factors associated with BMD were identified using an analysis of covariance model.

RESULTS

The study enrolled 331 women from Zimbabwe and 187 women from Uganda. Median age was 29 years (IQR 25, 32) and median body mass index (BMI) was 24.8 kg/m(2) (IQR 22.2, 28.6). In univariate analyses, lower TH BMD values were associated with residence in Uganda (p < 0.001), lower BMI (p < 0.001), and any use of and duration of depot-medroxyprogresterone acetate. Use of oral contraceptives, progestin-only implants, and higher physical activity levels were protective against reduced BMD. Similarly, lower LS BMD values were associated with these same factors but also higher parity and history of breastfeeding. In a multivariable analysis, lower TH and LS BMD values were associated with enrollment in Uganda, lower BMI, and lower physical activity level; contraceptive use was associated with lower spine BMD, and breastfeeding contributed to lower total hip BMD.

CONCLUSIONS

Among healthy premenopausal women, TH and LS BMD was higher in Zimbabwe than Uganda. Additional factors independently associated with BMD included BMI, physical activity level, contraceptive use, and lactation.

A pilot study examining short-term changes in bone mineral density among class 3 obese users of depot-medroxyprogesterone acetate

OBJECTIVE

To examine changes in lumbar spine-bone mineral density (LS-BMD) among normal weight (body mass index [BMI] = 18.5-24.9 kg/m(2)), Class 1-2 obese (BMI = 30-39.9 kg/m(2)), and Class 3 obese (BMI ≥ 40 kg/m(2)) women utilising depot-medroxyprogesterone acetate (DMPA).

METHODS

Five normal-weight, five Class 1-2 obese, and five Class 3 obese women received subcutaneous injections of DMPA-SC at baseline and 12 weeks later. Dual Energy X-ray Absorptiometry (DEXA) scans were performed at baseline and 18 weeks after the first injection for determination of LS-BMD and analysis of fat content. Bimonthly oestradiol (E2) levels were measured by immunoassay methods for 26 weeks.

RESULTS

There were no significant demographic or LS-BMD differences among the three BMI groups. Significant differences at baseline were as expected among the three groups with respect to BMI and associated parameters (mean % total body fat, absolute fat, and weight). When used as their own controls, significant changes in LS-BMD, % body fat and absolute fat determined by DEXA occurred among all three BMI strata. Class 1-2 obese and Class 3 obese women were more likely to experience E2 fluctuations, but short-term changes in LS-BMD were similar.

CONCLUSIONS

DMPA-SC administration affects L-spine bone health similarly regardless of BMI status.

Gonadotrophin-releasing hormone analogues and endometriosis: current strategies and new insights

BACKGROUND

Endometriosis is an estrogen-dependent chronic inflammatory disease affecting 5% to 10% of women in reproductive age and has been reported also in adolescents. Its main clinical presentations are chronic pelvic pain and infertility.

OBJECTIVE

To provide a comprehensive review of the recently published data concerning the mechanism of action of gonadotrophin-releasing hormone analogues (GnRHas) as well as to analyze their role in the management of endometriosis-associated pain and infertility in addition to its value in adolescent cases. Furthermore, to provide practical recommendations and new insights based on the best available information.

METHODS

Systematic search was performed of the Cochrane Library and Medical Literature Analysis and Retrieval System Online database looking for the different trials, reviews and various guidelines relating to GnRHas usage in the management of endometriosis-associated pain, infertility and in adolescent cases.

RESULTS

From a pathophysiological perspective, there is a growing scientific evidence that GnRHas exert its therapeutic effects by their classical pituitary downregulation and via a direct effect on the endometrial cells themselves. Accordingly, they represent an important medical option for the management of different aspects of this enigmatic disease.

CONCLUSION

GnRHas have a valuable strategic role in treatment of endometriosis-associated pain and infertility as well as in adolescents above 16 years.

Osteoporosis update

INTRODUCTION

Osteoporosis is a chronic disease that is estimated to affect more than 75 million people worldwide. The US Department of Health and Human Services projects that the disease will impact more than 10 million women by 2020 if efforts to prevent it are ineffective. This article provides an overview of the pathophysiology of osteoporosis, prevention measures, and an update of the US Food and Drug Administration-approved medications that are used in the treatment of this widespread disease.

METHODS

The current literature on the pathology, risks, and treatment of osteoporosis was reviewed. Studies providing the evidence for best practices are included in the following sections: prevention, diagnosis, and treatment of osteoporosis. Current national standards for diagnosis and treatment are highlighted.

RESULTS

Bisphosphonates continue to be the most popular and widely used pharmacologic treatment for osteoporosis. However, when bisphosphonates are contraindicated or cause side effects so serious that it is not possible for some women to use them, alternative pharmacologic treatments and forms of dosing are available.

DISCUSSION

When lifestyle and dietary modifications are insufficient to offset a diagnosis of osteoporosis, there are a variety of pharmaceutical options available that will provide safe and effective protection against fracture due to osteoporosis.

Counselling patients with uterine fibroids: a review of the management and complications

Fibroids are very common in Afro-Caribbean women. They can cause severe complications. The treatment modalities are not without risk and should be weighed against the complications of the fibroids.

Prescribing contraceptives for women with schizophrenia

Although women with serious mental illness have high rates of lifetime sexual partners, they infrequently use contraception. Consequently, the prevalence of sexually transmitted infections is high in this population. In addition, while the overall rate of pregnancy in women with schizophrenia of child-bearing age is lower than in the general population, the percentage of pregnancies that are unwanted is higher than that in the general population. The objective of this paper is to help clinicians explore knowledge of appropriate methods of contraception for women who suffer from schizophrenia. The authors reviewed recent literature on the use of contraceptive methods by women with schizophrenia treated with antipsychotic and adjunctive medications. Contraceptive counseling to women and their partners is an important part of comprehensive care for women with serious and persistent mental illness. Women with schizophrenia who smoke, are overweight, or have diabetes, migraine, cardiovascular disease, or a family history of breast cancer should be offered non-hormonal contraception. Women with more than one sexual partner should be advised on barrier methods in addition to any other contraceptive measures they are using. Clinicians should be alert for potential interactions among oral hormonal contraceptives, smoking, and therapeutic drugs. Long-lasting contraceptive methods, such as intrauterine devices, progesterone depot injections, or tubal ligation are reasonable options for women having no wish to further expand their families.

Reduced pelvic pain in women with endometriosis: efficacy of long-term dienogest treatment

Purpose

To investigate the efficacy and safety of dienogest as a long-term treatment in endometriosis, with follow-up after treatment discontinuation. The study included women with endometriosis, who had previously completed a 12-week, placebo-controlled study of dienogest, who participated in an open-label extension study for up to 53 weeks. Thereafter, a patient subgroup was evaluated in a 24-week follow-up after treatment discontinuation.

Methods

A multicenter study performed in Germany, Italy and Ukraine. Women with endometriosis were enrolled at completion of the placebo-controlled study (n = 168). All women received dienogest (2 mg once daily, orally) and changes in pelvic pain (on a visual analog scale), bleeding pattern, adverse events and laboratory parameters were evaluated during and after treatment.

Results

The completion rate among women who entered the open-label extension study was 90.5% (n = 152). A significant decrease in pelvic pain was shown during continued dienogest treatment (P < 0.001). The mean frequency and intensity of bleeding progressively decreased. Adverse events, rated generally mild or moderate, led to withdrawal in four patients (2.4%). No clinically relevant changes in laboratory parameters were observed. During treatment-free follow-up (n = 34), the reduction in pelvic pain persisted, while bleeding frequency and intensity returned to normal patterns.

Conclusions

Long-term dienogest showed a favorable efficacy and safety profile, with progressive decreases in pain and bleeding irregularities during continued treatment; the decrease of pelvic pain persisted for at least 24 weeks after treatment cessation.
