Copper containing intra-uterine devices versus depot progestogens for contraception

An in-vivo study of the safety of copper-containing intrauterine devices in 3.0 Tesla magnetic resonance imaging

PURPOSE

The aim of this study is to prospectively evaluate whether women with copper-containing intrauterine devices (Cu-IUD), currently listed as MR conditional, can safely undergo 3.0 Tesla (3 T) magnetic resonance imaging (MRI).

METHODS

73 women, age 18-54 years old, with a Cu-IUD who were undergoing MRI for any reason were included consecutively. Pre- and post-MRI standard pelvic ultrasound examinations were completed to determine the appropriate pre- and post-MRI positioning of the Cu-IUD. Displaced IUDs were defined by IUD crossbars not in the fundal portion of the endometrial cavity, a visualized tip in the mid or lower uterus, any part of the device located in the cervical canal or outside of the endometrial canal, a fractured device, or a non-visualized IUD. Additionally, a questionnaire was completed by participants to determine the level of pre- and post-MRI pelvic pain.

RESULTS

There were zero observed displaced Cu-IUDs on post-MRI pelvic ultrasounds (p = 0/70, 95% CI 0, .043). Three participants were dropped from the study due to malpositioned IUDs on pre-MRI pelvic ultrasound. Six patients reported new or worsening pelvic pain/discomfort during or after their MRI examination.

CONCLUSION

Our results suggest that performing 3 T MRI using a low SAR setting does not cause displacement of Cu-IUDs, with zero out of 70 patients demonstrating IUD displacement.

Immediate and delayed placement of the intrauterine device after abortion: a systematic review and meta-analysis

This article aims to report the comprehensive and up-to-date analysis and evidence of the insertion rate, expulsion rate, removal rate, and utilization rate of immediate placement of intrauterine devices (IUDs) versus delayed placement after artificial abortion. PubMed, Embase, Cochrane, Web of Science, CNKI, and Wanfang databases were comprehensively searched up to January 12, 2024 for studies that compared immediate versus delayed insertion of IUDs after abortion. The evaluation metrics included the number of IUD insertion after surgical or medical abortions, the frequency of expulsion and removal at 6 months or 1 year, the number of continued usage, pain intensity scores, the number of infections, the duration of bleeding, and instances of uterine perforation during or after IUD insertion. Ten randomized controlled articles were eligible, comprising 11 research projects, of which 3 projects involved the placement of an IUD after surgical abortion, and 8 projects involved the placement of an IUD after medical abortion. This included 2025 patients (977 in the immediate insertion group and 1,048 in the delayed insertion group). We summarized all the extracted evidence. The meta-analysis results indicated that for post-surgical abortions, the immediate insertion group exhibited a higher IUD placement rate than the delayed insertion group. After medical abortions, the immediate insertion group showed higher rates of IUD placement, utilization, and expulsion at 6 months or 1 year. The two groups showed no statistically significant differences in the removal rate, post-insertion infection rate, pain scores during insertion, and days of bleeding during the follow-up period. Compared to delayed placement, immediate insertion of IUDs can not only increase the usage rate at 6 months or 1 year but also enhance the placement rate.

Psychological, behavioural and physiological effects of three long-acting reversible contraception (LARC) methods: protocol for an ancillary study of the ECHO randomised trial

INTRODUCTION

This is the protocol for an ancillary study to the multicentre Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial, a three-arm randomised trial comparing the effects of depot medroxyprogesterone acetate (DMPA), the levonorgestrel (LNG) implant and the copper intrauterine device (IUD) on HIV incidence (NCT02550067 pre-results). The ancillary study will compare other non-contraceptive effects of these three long-acting, reversible contraceptions about which there is little existing comparative evidence.

METHODS AND ANALYSIS

Women randomised to IUD, DMPA and LNG implant (1:1:1) at one of the ECHO trial sites will be asked to participate in the ancillary study at the 1-month follow-up visit. Research staff will interview women that consent to participate at the 3-month follow-up visit. Primary outcomes are depression, sexual dysfunction and menstrual disturbances. The Beck Depression Inventory will be used to assess depression and the Arizona Sexual Experiences Scale to assess sexual dysfunction. Participants will also be asked to prospectively complete a 28-day symptom diary. The required sample size is 522 participants. Depression scores will be analysed as continuous and categorical variables. Analysis will be by intention to treat.

ETHICS AND DISSEMINATION

The ancillary study protocol received ethical approval from the University of the Witwatersrand Committee for Research on Human Subjects on 17 February 2016 (reference no. 14112). The results will be disseminated in a peer-reviewed open-access journal.

Effects of the copper intrauterine device versus injectable progestin contraception on pregnancy rates and method discontinuation among women attending termination of pregnancy services in South Africa: a pragmatic randomized controlled trial

BACKGROUND

The copper intrauterine device (IUD) is under-utilised in South Africa, where injectable progestin contraception (IPC) dominates contraception usage. There is a lack of robust comparative data on these contraceptive options to inform policy, programs, clinical counseling, and women's choices.

METHODS

Within the context of a South African program to increase women's access to the IUD, we conducted a pragmatic, open-label, parallel-arm, randomised controlled trial of the IUD versus IPC at two South African hospitals. The target sample size was 7,000 women and the randomisation ratio was 1:1. The random sequence was computer-generated and group allocation was concealed in sealed, opaque, consecutively-numbered envelopes. Counselled, consenting women attending termination of pregnancy services were randomly assigned to IUD or IPC immediately post-termination. Condoms were promoted for the prevention of sexually-transmitted infections. The primary outcome was pregnancy; secondary outcomes were discontinuation, side-effects, and HIV acquisition and disease progression. Pregnancy and discontinuation outcomes are reported here.

RESULTS

The trial closed early with 2,493 participants randomised (IUD = 1,247, IPC = 1,246), due to international concerns regarding a possible association between IPC and HIV acquisition. Median follow-up was 20 months; 982 and 1000 participants were followed up in the IUD and IPC groups, respectively. Baseline group characteristics were comparable. Pregnancy occurred significantly less frequently among women allocated to the IUD than IPC: 56/971 (5.8%) versus 83/992 (8.4%), respectively; risk ratio (RR) 0.69, 95% confidence interval (CI) 0.50 to 0.96; P = 0.025. There were more protocol violations in the IUD group; however, discontinuation rates were similar between IUD and IPC groups (141/855 [16.5%] and 143/974 [14.7%], respectively). Women in the IUD group were more likely to discontinue contraceptive use due to abdominal pain or backache and non-specific symptoms, and those in the IPC group due to oligo- or amenorhoea and lack of sexual activity.

CONCLUSIONS

The IUD was significantly more effective in preventing pregnancy than IPC. Efforts to expand contraception options and improve access to the IUD in settings where it is under-utilised are worthwhile. This trial shows that randomising long-acting, reversible contraceptives is feasible.

Intrauterine devices and other forms of contraception: thinking outside the pack

A variety of contraception options are available in addition to traditional combined oral contraceptive pills. Newer long-acting reversible contraceptive (LARC) methods such as intrauterine devices and subcutaneous implants are preferred because they do not depend on patient compliance. They are highly effective and appropriate for most women. Female and male sterilization are other effective but they are irreversible and require counseling to minimize regret. The contraceptive injection, patch, and ring do not require daily administration, but their typical efficacy rates are lower than LARC methods and similar to those for combined oral contraceptive pills.

Positive Testing for Neisseria gonorrhoeae and Chlamydia trachomatis and the Risk of Pelvic Inflammatory Disease in IUD Users

BACKGROUND

Unintended pregnancies are a major public health problem in the United States, and intrauterine devices (IUDs) are among the most effective reversible birth control methods available. Historically, there have been concerns about IUD use and infection among young and/or high-risk women that may increase the risk of pelvic inflammatory disease (PID) and subsequent infertility.

METHODS

The Contraceptive CHOICE Project (CHOICE) was a prospective cohort study of over 9,000 women 14-45 years of age residing in the St. Louis area who were interested in initiating a new form of reversible contraception. At enrollment, participants were counseled regarding long-acting contraceptive methods with the goal of increasing awareness of all reversible methods available. Participants were also tested for Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) during enrollment and were provided with contraception at no cost for 2-3 years.

RESULTS

We estimate the frequency of self-reported PID in new IUD users compared with women using other contraceptive methods. Among both new IUD users who tested positive for GC and/or CT and those who tested negative, the PID rate was 1% or below.

CONCLUSIONS

Our results demonstrate that IUD use is safe for all women, including women at high risk for sexually transmitted infections.

Contraceptive options for HIV-positive women: making evidence-based, patient-centred decisions

OBJECTIVES

Women of reproductive age represent a large proportion of the global population living with HIV/AIDS. With improvements in morbidity and mortality since the advent of combination antiretroviral therapy, contraception and pregnancy planning are an increasingly important issue for women living with HIV. This review aims to outline the key considerations when choosing contraceptive methods in HIV-positive women and provides a review of the literature to inform decision-making.

METHODS

Pubmed was searched using the terms 'HIV', 'contraception', 'HIV progression', 'HIV acquisition', 'HIV transmission' and the combination of 'antiretroviral' and 'contraception'. Abstracts were reviewed and relevant articles were retrieved. Reference lists were also reviewed for pertinent citations.

RESULTS

HIV and contraceptive methods can interact in several clinically meaningful ways. Concomitant use may result in altered contraceptive efficacy, drug-drug interactions, or increased toxicity. Hormonal contraceptives have not been shown to affect HIV progression. Notably, the impact of hormonal contraceptives on HIV transmission and acquisition remains unclear, particularly for injectable forms. Data are lacking on several newer methods of contraception including contraceptive rings, patches and intrauterine systems.

CONCLUSIONS

Effective, reliable contraception is important for HIV-positive women. Efficacy, toxicity, drug interactions, and potential impacts on HIV disease progression, transmission, and acquisition must be assessed when making clinical decisions.
