VIH-1 Colo-rectal Transmission by Infected Semen Cells and Effects of Seminal Plasma ex Vivo (CellspermVIH) (CellspermVIH)
VIH-1 Colo-rectal Transmission by Infected Semen Cells and Effects of Seminal Plasma ex Vivo
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
This project relies on:
- our expertise of HIV in semen and male genital tract and our experience in organotypic cultures;
- a network of infectious diseases and reproductive biology clinicians to collect, analyze and process seminal cells and seminal plasma from HIV+ donors;
- the expertise in confocal microscopy and ex vivo colo-rectal model. State of the art culture of colo-rectal tissues, primary cell culture and infection, confocal microscopy, flow cytometry, Polymerase Chain Reaction and Luminex assays for cytokine measurements will be the methodologies primarily used in this project.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
The duplicated part of the CRFs will then be sent to Mrs DEJUC at the IRST in Rennes, the remaining part will be kept in the investigating center.
All the data of the study transcribed by the investigator in the CRFs will be transmitted electronically to the person in charge of the data of the INSERM / IRSET 1085 unit. Upon receipt, the data will be entered simply by typing and re-reading on the Excel spreadsheet. The files will be locked by password and backed up daily with storage for 3 months on the server of the INSERM 1085 unit managed by the IT department of the University of Rennes 1. The set Data is saved every evening, with storage for 4 weeks, then archived monthly on tape.
