Effects of Copper Versus Levonorgestrel Intrauterine Devices on Mucosal Microbiota and Barrier Function Among Young African Women
Effects of Copper Versus Levonorgestrel Intrauterine Devices on Mucosal Microbiota and Barrier Function: a Randomized Trial Among Young African Women
The goal of this clinical trial is to definitively determine whether copper intrauterine device (IUD) or hormonal intrauterine system (IUS) results in greater vaginal microbial diversity after 1 year in women (n= approximately 120) aged 18-40 years, who desire to use a copper IUD or hormonal IUS as contraception, are HIV-negative and could benefit from STI prevention.
The main questions it aims to answer are:
- Whether women assigned to copper IUD vs hormonal IUS have differences in vaginal microbial diversity after 1 year of use
- Whether women randomized to Copper IUD have reduced genital mucosal barrier integrity as indicated by proteomic signatures
- Whether women randomized to Copper IUD have greater incidence of high-risk HPV or curable STIs (Ct, Ng, Tv)
Participants will be assigned to have either the copper IUD or the hormonal IUS inserted as contraception. After that, they will have blood and vaginal fluids collected every 3 months for one year to look at the bacteria in their vagina, test for sexually transmitted infections, and examine markers of vaginal health.
After enrolment, each participant will be followed for 12 months, and at the end of the trial, the participant can continue to use the IUD/IUS or the study clinician can remove it.

Aktivní komparátor: Copper T-380 intrauterine device (Cu-IUD)
The Cu-IUD will be Model TCu 380A used in public sector services in Kiambu County. Each T-shaped plastic frame has 176 mg of copper wire coiled around its vertical arm and a copper collar of 68 mg of copper on each of its transverse arms for a total copper surface area on the device of 380 mm2. The product will be sterile and will be inserted as described in the package insert. |
Product will be used as labeled for approximately 12 months.

Aktivní komparátor: Levonorgestrel intrauterine system (LNG IUS)
The LNG-IUD consists of a T-shaped polyethylene frame with a steroid reservoir containing 52 mg levonorgestrel packaged with a sterile inserter. The product will be sterile and will be inserted as described in the package insert |
Product will be used as labeled for approximately 12 months.

Comparisons of host epithelial integrity factors via metaproteomics
Časové okno: From enrollment to the end of participation at 12 months

Differential abundance of host proteins will be evaluated using the limma package in R, for each arm, adjusting for potential confounders, and functional enrichment analysis conducted using DAVID.
Evaluation of proteomic changes using the MEFISTO R package will be used.
The mixOmics R package will be used to identify the minimum protein signature most associated with different contraceptives will be evaluated using sparse PLSDA and Data Integration Analysis and Biomarker discovery using Latent cOmponents (DIABLO).
Microbial functional changes will be investigated by aggregation of proteins with the same Gene Ontology.
