Intrauterine devices and adolescents

Utility of the Levonorgestrel-Releasing Intrauterine System in the Treatment of Abnormal Uterine Bleeding and Dysmenorrhea: A Narrative Review

INTRODUCTION

We undertook a literature review of the use of levonorgestrel-releasing intrauterine devices when utilized for heavy menstrual bleeding and/or dysmenorrhea.

METHODS

A narrative review of articles in the Scopus and Medline databases was conducted.

RESULTS

A number of options exist for the management of both abnormal uterine bleeding (AUB) and dysmenorrhea, and evidence is accumulating that the insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) represents a useful option for their long-term treatment. The idea of using a progestogen released in utero was initially conceived to achieve long-term contraception, but it was quickly found that these systems could be utilized for a number of therapeutic applications. The first device to be made commercially available, Progestasert, was withdrawn from the market because, in the event of contraceptive failure, it caused a disproportionate percentage of extrauterine pregnancies. On the other hand, the LNG-IUS continues to be successfully utilized in its various variants, releasing 20, 13, or 8 μg/day. These devices have a respective duration of action of 7 (possibly 8), 5, and 3 years, and there exist versions of frameless systems affixed to the myometrium of the uterine fundus. In the present review, following a brief description of the major causes of AUB and dysmenorrhea, the molecular bases for the use of the LNG-IUS are summarized. This is followed by a compendium of its use in AUB and dysmenorrhea, concluding that the insertion of the system improves the quality of life, reduces menstrual blood loss better than other medical therapies, and decreases the extent of dysmenorrhea and pelvic pain. In addition, there is no evidence of a significant difference in these outcomes when the use of the LNG-IUS was compared with improvements offered by endometrial ablation or hysterectomy. Possibly, the most important mechanism of action of the system consists of its ability to induce amenorrhea, which effectively eliminates heavy bleeding and dysmenorrhea. However, no method is ideal for every woman, and, in the case of the LNG-IUS, younger age and severe dysmenorrhea seem to be associated with a higher risk of discontinuation.

CONCLUSION

The higher-dose LNG-IUS is a useful tool for HMB and dysmenorrhea in women of all ages. The low cost and ease of use make the LNG-IUS an attractive option, especially when contraception is also desired.

The acceptability of using IUDs among Egyptian nulliparous women: a cross-sectional study

Background

Although intrauterine contraceptive device is highly effective, safe, long term and reversible method of contraception, the general population and physicians refuse. IUDs for nulliparous women due to persistent rumors about its side effects and complications. The aim of this study was to assess the acceptability of IUD use in nulliparous women by both women and health care providers in Egypt.

Methods

Five hundred thirty nulliparous women and 200 physicians were interviewed in 10 family planning clinics in Suez and Minia cities – Egypt. The knowledge and attitudes of women and health care providers towards IUD use in nulliparous women were assessed through a well designed questionnaire over 2 years. Those women who accepted using IUD were then followed up for 6 months.

Results

Most of nulliparous women sought for contraception reported a negative impression of IUD method (96.2%). 82.5% of physicians had the same attitude. The reasons for refusing IUD among nulliparous women are fear of side effects including infection (52.8%), and bleeding (37.7%).Also, fear of subsequent infertility 51.9% of women. Regarding the providers, increased pelvic inflammatory disease (PID) represented the highest percentage (70%) for non acceptability, followed by difficult insertion (52.5%). Ninety women who accepted use IUD were followed up 6 months later, 94.4% were still using the method and77.8% were happy with the results.

Conclusion

The main barriers that hinder the use of IUD in nulliparous women are the women insufficient knowledge and attitude of their physicians. Good client counseling. Good training for physician to improve their experience would help increase the use of such effective and safe method.

A systematic review of the views of healthcare professionals on the provision of long-acting reversible contraception

RESEARCH QUESTION

What are the views of healthcare professionals outside of the general practice setting on long-acting reversible contraception?

BACKGROUND

Despite global sexual health organisations advocating for widespread prescription of long-acting reversible contraception, uptake in developed countries remains relatively low. The role of healthcare professionals outside of the general practice setting in long-acting reversible contraception provision requires further attention.

DESIGN

Systematic review.

METHODS

Five electronic databases were searched for existing qualitative findings using terms related to long-acting reversible contraception and healthcare professional views for the period 2013-2018. A rigorous protocol was applied following the Preferred Reporting Items for Systematic Meta-Analyses checklist and flow diagram. The Critical Appraisal Skills Programme tool was used to assess the quality of studies. A total of six studies were included for thematic analysis.

RESULTS

Three key themes emerged through analysis that had significant impact on healthcare professional views of long-acting reversible contraception: (a) contraceptive counselling practices and constraints; (b) knowledge and training about long-acting reversible contraception; and (c) concerns and personal beliefs about long-acting reversible contraception.

CONCLUSIONS

Healthcare professional views on long-acting reversible contraception are shaped by practical time constraints, levels of knowledge and training, and personal beliefs and concerns. Further research is required to address these issues in order to improve clinical training and guidelines for all settings, not just general practice.

RELEVANCE TO CLINICAL PRACTICE

Settings outside of general practice need to be included within the scope of initiatives that aim to improve clinical practice around access to new and emerging contraceptive methods. Further research could inform models of clinical practice that enable healthcare professionals to take enough time to talk through all contraceptive options with patients in a way that both focuses on their individual needs and is fully informed by up-to-date evidence and training.

Association of HIV status with infection by multiple HPV types

OBJECTIVES

To identify the clinical and demographic characteristics of HIV-positive and HIV-negative women infected by multiple HPV types.

METHODS

1399 women participated in the study (240 HIV-positive and 1159 HIV-negative women). Samples were provided for Pap tests and for HPV detection and typing by PCR. Data were collected on HPV infection, frequency of multiple infection, and HPV type distribution. Odds ratios were reported from logistic regression models.

RESULTS

Compared with HIV-negative women, HIV-positive women had higher frequencies of cervical abnormality (30% vs. 20.8%), higher HPV prevalence (68.3% vs. 51.3%) and were more commonly infected with multiple HPV types (78.7% vs. 44.3%). HPV-16 was the most common type detected in the study population, with other types showing variable associations with HIV status. Positive associations were observed between infection by multiple HPV types and HIV status, cervical abnormality and having had more than three pregnancies. The odds of multiple infection by HPV types were higher in HIV-positive women who used an intrauterine device, who had a history of abortions and who had HIV viral loads >100 000 copies/ml, whilst the odds were lower in women with >500 CD4 cells/mm³ .

CONCLUSIONS

HIV immunosuppression favours infection by multiple high-risk HPV types, mainly in women affected by low-grade squamous intraepithelial lesions. Antiretroviral therapy had no effect on infection by multiple HPV types. Risk factors related to progressive damage to the cervix were positively associated with infection by multiple HPV types in women living with HIV.

Predictors of Early Discontinuation of Effective Contraception by Teens at High Risk of Pregnancy

STUDY OBJECTIVE

In the United States, teen pregnancy rates are declining. However, the United States still has the highest teen pregnancy rate among high-income countries. Understanding factors that predict discontinuation of effective contraception might help to further decrease teen pregnancy. We aimed to assess predictors of early discontinuation of effective contraception during typical use by high-risk teens. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We recruited 145 women aged 13-20 years (mean, 17.7 ± 1.8 years); 68% (99/145) Hispanic; 26% (38/145) black; 14% (20/145) ever pregnant; and 4% (6/145) high school dropouts who chose an effective contraceptive method during a health care visit and we prospectively assessed use of the method after 6 months. Contraceptive choices of the 130 participants who were reassessed at 6 months (90% retention) were: intrauterine device (IUD), 26% (34/130); depot medroxyprogesterone acetate (DMPA), 8% (10/130); combined oral contraceptives (COCs), 48% (62/130); transdermal patch (Patch), 13% (17/130); and intravaginal ring (Ring), 5% (7/130).

RESULTS

After 6 months, only 49 of 130 (38%) continued their chosen method; 28 of 130 (22%) never initiated the method; and 53 of 130 (40%) discontinued. Users and nonusers at 6 months did not differ according to cultural and/or social characteristics (age, ethnicity, acculturation, education, health literacy) but differed according to contraceptive method type. For the 102 of 130 who initiated a method, 88% continued use of the IUD, 20% DMPA, 43% COC, 17% Patch and Ring (P < .001). Using Cox proportional hazards multivariable analysis, compared with IUDs, all other methods predicted discontinuation: DMPA (hazard ratio [HR], 5.6; 95% confidence interval [CI], 1.2-26.7; P < .05); COCs (HR, 6.6; 95% CI, 1.8-25; P < .01); Patch and Ring (HR, 12; 95% CI, 3.0-48; P < .001). Discontinuation was also predicted by past use of hormonal contraceptives (HR, 1.9; 95% CI, 1.0-3.6; P < .05) and high school dropout (HR, 8.2; 95% CI, 1.6-41; P < .01).

CONCLUSION

Contraceptive method type is the strongest predictor of early discontinuation; compared with IUDs, all other methods are 6-12 times more likely to be discontinued. Cultural and/or social characteristics, with the exception of school dropout, are of little predictive value. Increasing the use of IUDs by high-risk teens could decrease discontinuation rates and possibly teen pregnancy rates.

Let's talk about sex (again): advancing the conversation around long-acting reversible contraception for teenagers

Long-acting reversible contraception (LARC) has incredible potential for decreasing teenage pregnancy rates in the USA, but use among adolescents remains low. LARC methods, including intrauterine devices and implants, are recommended as first-line choices for teenagers by multiple medical professional associations. Barriers at the system, provider and patient level persist, but new demonstration projects, in addition to provisions of the Affordable Care Act, show great promise in facilitating LARC use. A renewed national discourse should acknowledge the reality that many US teenagers have sex, that LARC is safe and effective and that LARC offers an opportunity to prevent teenage pregnancy. By encouraging widespread access and use, a large, positive impact across multiple health and economic sectors can be achieved.

Complication rates associated with levonorgestrel intrauterine system use in adolescents with developmental disabilities

STUDY OBJECTIVE

To assess the complication rates with the use of the levonorgestrel intrauterine system (LNG IUS) in adolescents with developmental disabilities.

DESIGN

Retrospective chart review of all adolescents with developmental disabilities taken to the operating room for LNG IUS insertion between January 2000 and July 2009 at the Royal Children's Hospital, Melbourne, Australia. Cases identified from the surgical database, and medical records reviewed.

MAIN OUTCOME MEASURES

Complication rates with LNG IUS use in adolescents with development disabilities: non-insertion, uterine perforation, infection, and expulsion.

RESULTS

Fifty-six adolescents with developmental disabilities had an attempted LNG IUS insertion. The average age at insertion was 15.6 years (range 10.5-21.5 y). The LNG IUS was used as first line therapy in 14 cases (25%). Pre-insertion ultrasonography was ordered in 48% of cases, out of which 5 cases had uterine lengths <6 cm. Despite this, 4 of these cases had successful insertions. Two insertion attempts were abandoned intra-operatively (3.6%); one due to inadequate uterine length of 4 cm, and the other due to anatomic distortion. One spontaneous expulsion occurred at approximately 5 months (1.9%). Four IUDs were removed prematurely (7.4% withdrawal rate); 1 for persistent abdominal pain, 1 for irregular bleeding, and 2 for suspected malpositions. There were no documented cases of infection, perforation, or pregnancy.

CONCLUSION

Our experience in this population has been very positive and confirms that complication rates are comparable to that in adults.

Pediatricians' beliefs and prescribing patterns of adolescent contraception: a provider survey

STUDY OBJECTIVE

Teen pregnancy and sexually transmitted infection (STI) rates continue to be significant public health problems in the United States. While general pediatricians are in a unique position to improve these issues by addressing contraception with their adolescent patients, there are no data describing their current prescribing patterns. This study sought to elucidate the beliefs and prescribing patterns of general pediatricians and pediatrics residents and to distinguish whether these were affected by practice setting, level of training, or gender.

DESIGN, SETTING, PARTICIPANTS

General pediatricians and pediatrics residents affiliated with Lurie Children's Hospital in Chicago, IL, were asked to complete a survey regarding adolescent contraception.

MAIN OUTCOME MEASURES

Questions were related to obtaining information about contraception, contraceptive counseling, knowledge of contraceptive methods, prescribing patterns of contraceptives, and concerns about individual contraceptive methods.

RESULTS

120 physicians of an eligible 411 physicians participated in this study (29%). 79% of participants had prescribed at least 1 contraceptive method. The most commonly prescribed method was oral contraceptive pills at 72%. We noted few differences in prescribing patterns based on above criteria. Numerous misconceptions existed among participants, including a high rate of concern about infertility with IUD use (29% among physicians who prescribed at least 1 method of contraception).

CONCLUSIONS

General pediatricians can improve their rates of prescribing contraception to adolescents, and could utilize more of the approved methods. One way to do so may be to implement educational interventions among general pediatricians.

Levonorgestrel intrauterine system as a treatment option for severe menorrhagia in adolescent with type III von Willebrand disease

The authors describe a case of an adolescent with type III von Willebrand disease and severe menorrhagia since menarche. Antifibrinolytic, hormonal (estroprogestative pill in high doses, etonogestrel implant and gonadotropin-releasing hormone agonist goserelin) and Von Willebrand Factor/Factor VIII replacement therapies were prescribed to the patient, but symptomatic control was only obtained with high doses of VWF/FVIII twice a week. In March 2012, a levonorgestrel intrauterine system was inserted in a 14-year-old. At present, the patient is asymptomatic without regular prophylaxis (VWF/FVIII replacement therapy) and has had a remarkable improvement in her quality of life.

Identifying counseling needs of nulliparous adolescent intrauterine contraceptive users: a qualitative approach

PURPOSE

To describe the intrauterine contraception (IUC) adoption process among nulliparous adolescents and to identify the role of the medical provider in this trajectory.

METHODS

We conducted semistructured interviews with a clinic-based sample of 20 nulliparous adolescents (aged 15-24 years) with a history of IUC use. Interviews were analyzed using modified grounded theory and cross-case analysis to reveal a process model for IUC adoption, with a focus on the role of the medical provider.

RESULTS

The model includes the following stages: first awareness, initial reaction, information gathering, adoption, and adjustment and reassessment. It is influenced by personal preferences and experiences, friends, family, sexual partner(s), and medical providers. Interactions with medical providers that study participants found helpful in navigating the adoption process included the use of visuals; tailored counseling to address specific contraceptive needs; assurance that IUC discontinuation was an option; information on a wide range of side effects; medical provider self-disclosure regarding use of IUC; and addressing and validating concerns, both before and after IUC insertion.

CONCLUSIONS

Nulliparous adolescents in this study described a complex IUC adoption process in which the medical provider plays a substantial supportive role. Findings from this study may be used to counsel and support future nulliparous adolescents regarding IUC use.

Continuation of reversible contraception in teenagers and young women

OBJECTIVE

To examine the effect of age on continuation rates of reversible contraceptive methods among females aged 14-19 years and women aged 20-25 years compared with women older than 25 years of age.

METHODS

We analyzed data from 7,472 participants enrolled in the Contraceptive CHOICE Project, a prospective cohort study of women offered no-cost contraception. Our primary objective was to compare 12-month continuation rates between females aged 14-19, 20-25, and 26 years and older. We collected data about method continuation from telephone surveys and chart review. We used Kaplan-Meier survival curves to estimate continuation and Cox proportional hazard models to examine the risk of contraceptive method discontinuation.

RESULTS

Twelve-month continuation of long-acting reversible contraceptive (LARC) methods was more than 75% for all age groups. Females aged 14-19 years using LARC methods had slightly lower continuation rates (81%) than older women (85-86%), but this did not reach statistical or clinical significance. Compared with women older than 25 years of age, females aged 14-19 years had higher discontinuation rates for non-LARC methods (53% compared with 44%; adjusted hazard ratio 1.32, 95% confidence interval [CI] 1.02-1.73). The females aged 14-19 years were less likely to be satisfied with non-LARC methods (42% compared with 51%; adjusted relative risk 0.80, 95% CI 0.65-0.98), but not with LARC methods (75% compared with 83%; relative risk 0.94, 95% CI 0.88-1.01) when compared with women older than 25 years of age; however, the differences were small.

CONCLUSION

Teenagers and young women have high rates of LARC method continuation.

Knowledge and likelihood to recommend intrauterine devices for adolescents among school-based health center providers

PURPOSE

The American College of Obstetricians and Gynecologists and the Centers for Disease Control and Prevention recommend intrauterine devices (IUDs) as safe and highly effective contraceptives for adolescents. Nevertheless, many U.S. providers do not recommend or provide IUDs to adolescents-a population at high risk for unintended pregnancy. The purpose of this study was to identify barriers to IUD provision for adolescents.

METHODS

A 36-item self-administered survey of knowledge and attitudes regarding IUDs was completed by 162 staff of New York City school-based health centers, including 69 clinicians (e.g., pediatricians and nurse practitioners) and 93 nonclinicians (e.g., social workers and health educators).

RESULTS

Half (55%) of all respondents would be likely to recommend an IUD to a patient under age 20 years. Respondents were less likely to recommend an IUD for patients with history of recent STD (31%), remote pelvic inflammatory disease (37%), and patients not in a monogamous relationship (38%). Whereas 77% of respondents indicated that IUDs are safe for adolescents, 18% of those respondents would be unlikely to recommend an IUD to a patient under age 20 years. While 86% of respondents knew that IUDs can be used in nulliparous women, 25% of those respondents would be unlikely to recommend an IUD to a patient who has never been pregnant. Additionally, 61% believed that counseling patients about IUDs would take more time than other methods.

CONCLUSIONS

Misinformation about risks associated with IUDs and beliefs about patient eligibility may present barriers to provision. Apparent contradictions between knowledge and likelihood to recommend IUDs warrant further study.

Contraception in HIV-positive female adolescents

Sexual behavior of HIV-positive youths, whether infected perinatally, through risky behavior or other ways, is not substantially different from that of HIV-uninfected peers. Because of highly active antiretroviral therapy, increasing number of children, infected perinatally, are surviving into adolescence and are becoming sexually active and need reproductive health services. The objective of this article is to review the methods of contraception appropriate for HIV-positive adolescents with a special focus on hormonal contraceptives. Delaying the start of sexual life and the use of two methods thereafter, one of which is the male condom and the other a highly effective contraceptive method such as hormonal contraception or an intrauterine device, is currently the most effective option for those who desire simultaneous protection from both pregnancy and sexually transmitted diseases. Health care providers should be aware of the possible pharmacokinetic interactions between hormonal contraception and antiretrovirals. There is an urgent need for more information regarding metabolic outcomes of hormonal contraceptives, especially the effect of injectable progestins on bone metabolism, in HIV-positive adolescent girls.

The wandering Mirena: laparoscopic retrieval

Levonorgestrel-containing intrauterine contraceptive devices, marketed as Mirena (Bayer HealthCare Pharmaceuticals, Inc. Australia) are widely used in contemporary gynecology, primarily as an effective method for contraception and for control of menstrual disorders like menorrhagia and dysmenorrhea. In this article, the authors report 2 cases of Mirena migration following intrauterine insertion by general practitioners (family physicians). In the first case, the contraceptive device had moved to the patient's right iliac fossa just anterior to the cecum and, in the second, within the peritoneal cavity close to the left leaf of the diaphragm. Both patients underwent uneventful laparoscopic retrieval of the devices.

Design and application of a flexible and implantable sensor for detecting uterine musculature contraction

It is very important to obtain the parameters of deformation size and contraction frequency of women's uterine musculature in medical research. This paper proposes a type of sensor for measuring these parameters and analyzes its force situation. The flexibility of the sensor makes it easy for doctors to let the sensor pass through woman's narrow cervix and get to her uterine cavity. The experiment shows that the sensitivity of three coils in the sample sensor achieves 22.38 nH/mm(2) both for left and right coils, 22.84 nH/mm(2) for top coil, which can meet the requirements of sensitivity for testing the contraction situation of uterine musculature. Furthermore, an interface designed in the back end system can display the parameters of deformation size and vivid contraction situation of women's uterine musculature in real-time. The sensor has been applied in some medical fields.

Cornual pregnancy as a complicaton of the use of a levonorgestrel intrauterine device: a case report

INTRODUCTION

Complications of copper load intrauterine devices, including ectopic pregnancies are well reported. Rates of ectopic pregnancy are 0.6 to 1.1% per year. However, the levonorgestrel intrauterine device has been described as more protective against ectopic pregnancies due to the addition of the hormone levonorgestrel. The hormone released from the intrauterine device causes some systemic effects, but local effects such as glandular atrophy and stromal decidualization, in addition to foreign body reaction, are dominant. Few case reports have described ampullary ectopic pregnancies. However, we report, for the first time, a major complication of levonorgestrel intrauterine device: a cornual pregnancy.

CASE PRESENTATION

A 36-year-old Caucasian nulliparous woman presented with complaints of progressive nausea, abdominal pain and irregular vaginal bleeding for 2 months. For 3 years, she had been using a levonorgestrel intrauterine device. A two-dimensional transvaginal sonogram noted a sac situated external to the endometrial cavity in the right cornua of the uterus with an empty uterus. She was successfully treated with chemotherapy.

CONCLUSION

Many complications have been described, including ectopic pregnancies, using copper intrauterine devices. The levonorgestrel-releasing intrauterine system is a particularly good choice for adolescents because of associated non-contraceptive benefits such as decreased menstrual bleeding, dysmenorrhea and pain associated with endometriosis [1]. Yet a cornual pregnancy following the use of a levonorgestrel intrauterine device is a complication which, to our knowledge, has not been described before. Physicians prescribing this type of intrauterine device should be aware of this rare event.
