DELTA DESCRIBE: the French Collaborative Project

Recruiting
Conditions
Hepatitis D
Registration Number
NCT05936073
Lead Sponsor
University Hospital, Limoges
Brief Summary

Our global objective is to draw up a photograph of HDV patients over one year in metropolitan France and identify the barriers of screening and care. The investigator suspects a mismatch between HBV and HDV screening, the first step for specialized care pathway in metropolitan France.

Detailed Description

Hepatitis Delta virus (HDV) infection is a significant public health disease causing up to 18% of cirrhosis and 20% of hepatocellular carcinoma (HCC) and new therapeutic options are now available. In France, very few epidemiological studies, mainly focused on specific pre-selected hospital populations, are available. There is a crucial need for data in terms of Delta knowledge, suitability of screening, type of prescribers and treatment access. The investigator proposes a retrospective study in order to describe the number of HDV tests (anti-HDV and HDV RNA) performed in metropolitan France and compare it to the potentially expected one, estimated from the number of HBV screening tests performed in one year, from 2016 to 2020. The investigator will also evaluate the number of HCV and HIV screening tests prescribed over the same period and the HDV PCR techniques used. This study will be based on one hand on data from the French Health insurance (first step) and on the other hand on data from private and hospital laboratories (second step). The second step will allow to identify the prescriber of the Delta tests and the HDV positive patients and precise their profile and their medical care. After an initial analysis of the results, The investigator will propose solutions to the barriers encountered and adapted to the identified targets.
