Investigating the Interaction Between Two Long-acting Reversible Methods of Contraception and Dolutegravir, a Treatment for HIV

It is important to make sure that women have access to effective methods of contraception to prevent pregnancy so that they can make choices about when and if they will have their first or next child. Some of the most effective methods of contraception are the long-acting, reversible methods of contraception (LARCS), including the contraceptive implant and the contraceptive injection. In areas of the world where there are high numbers of people living with HIV, providing contraception to women is sometimes complicated, as there are known to be interactions between some of the medications that treat HIV and some hormonal methods of contraception. One medication to treat HIV, dolutegravir, is now one of the first-line treatments for HIV in Botswana, and more and more women of childbearing age are taking dolutegravir to treat HIV. At the moment, there is limited information on whether or not there are interactions between dolutegravir (the HIV medication) and the contraceptive implant or the contraceptive injection, two commonly used methods of contraception in Botswana. The main purpose of this study is to find out if women using contraception and also taking dolutegravir have lower levels of contraceptive hormone in their blood compared to women taking no HIV treatment. The study hypothesis is that there is no interaction between dolutegravir and the contraceptive implant or injection. In this study, levels of hormone from the injection or the implant will be measured in women living with HIV who take dolutegravir and compared to hormone levels in women who do not have HIV and who have never taken any medications to treat HIV. Women will be counselled about all of the possible methods of contraception (including the pill, the injection, the implant and the copper intrauterine device (or coil/loop)) that are available and will be empowered to make their own decision about the method of contraception they feel will be best for them. Women who choose the implant or the injection will be invited to enrol in the study; and will be categorised into one of four groups, based on whether or not they are living with HIV and taking dolutegravir. At several time points, women will have blood tests to check the level of hormone from the implant or the injection, over a course of 12 weeks for women starting the injection and 24 weeks for women starting the implant. Women will also be asked to complete a short questionnaire about any side effects from the contraception including changes to bleeding patterns. At the end of the 12 weeks (for women starting the injection) or 24 weeks (for women starting the implant), the results from these blood samples will be analysed to see how the levels of the hormone in their blood changed over time. The study will also look at whether the levels of dolutegravir (the HIV medication) changed over time. These results will be compared between women living with HIV taking dolutegravir and women without HIV who have never taken dolutegravir to see whether there is any interaction between dolutegravir and the hormonal contraceptive implant or contraceptive injection.

The Aim of This Study is to Estimate the Discontinuation Rate of Low-dose Levonorgestrel-releasing Intrauterine System Due to Self-reported Unacceptable Menstrual Bleeding Pattern in Spanish Women Who Are Using it for the First Time How Intrauterine System for Long Acting Contraception

Researchers are looking for better ways to help women prevent pregnancy. Every month, a woman's body prepares for pregnancy in a process called the menstrual cycle. When pregnancy does not happen, menstruation occurs. During menstruation, women lose blood and tissue from inside the womb. This bleeding can last for about 2 to 7 days. Hormonal intrauterine contraception aims to help women prevent pregnancy by stopping the process of the menstrual cycle. Intrauterine means that the contraception is in the form of a device that is inserted into a woman's womb by her doctor. The device then releases the contraception into the womb. Researchers have found that when women use hormonal contraception, the disruption to the menstrual cycle can cause changes to how often and for how long women will bleed. So, the researchers in this study want to learn more about the menstrual bleeding patterns of women in Spain who are using hormonal intrauterine contraception for the first time. In other words, In particular for the LNG-IUSs, irregular bleeding due to the local effect of levonorgestrel on the endometrium is common, particularly during the first 3 months of use, and it is of interest to know if this is a major reason why Spanish women discontinue this very effective method and what other factors may be associated with discontinuation. The researchers will then use this information to estimate how many women choose to stop using the contraception. The participants will be able to enroll in this study after requesting hormonal intrauterine contraception from their doctor. They will be women between the ages of 18 and 35 who have never used hormonal intrauterine contraception before. The participants will visit the study site 3 times. On the first visit, they will receive the hormonal intrauterine contraception. The doctors will also check their health to make sure they can join the study. The participants will visit the study site again 4-12 weeks later, and one last time after 1 year of having the hormonal intrauterine contraception. During these visits, the doctors will ask the participants questions about any medical problems they have and if they want to continue using the contraception. Throughout the study, the participants will use a mobile app to track information about their menstrual bleeding and how they feel about it.
