简要总结
Congenital cytomegalovirus (CMV) infection is the most common congenital infection with a birth prevalence of 0.4% in Europe. It is the leading non-genetic cause of sensorineural hearing loss and a major cause of neurodevelopmental disabilities. The risk of intrauterine transmission is highest when primary infection occurs during pregnancy. Primary CMV infection is asymptomatic or causes non-specific symptoms and only serology can diagnose it with certainty.
The diagnosis of CMV infection is based on the combination of 2 or 3 serological markers and the interpretation of the results is more complex than for other infections and may require additional analyses and sometimes delay the diagnosis and the implementation of secondary prevention of CMV transmission to the fetus by the administration of valaciclovir. Indeed, the effectiveness of secondary prevention is conditioned by the early administration of treatment after the maternal primary infection.
The National Reference Center for Congenital CMV Infections at Necker Hospital, in collaboration with the virology laboratory at Paul Brousse Hospital, has developed the MyCMV "expert" tool, which is a decision-making algorithm that allows the interpretation of CMV serology and CMV PCR results.
The hypothesis of the study is that the use and provision of this MyCMV "expert" tool to health professionals (biologists, midwives and obstetricians) for the interpretation of virological results could avoid a delay in diagnosis and would allow patients to be referred more quickly to a prenatal diagnosis center for appropriate management of CMV infection.
The aim of the study is to evaluate the rate of detection of primary CMV infection in the first trimester of pregnancy using the MyCMV tool compared with the reference method (results interpreted by the centre's expert investigator).

We also aim to evaluate the dating of the maternal primary infection in weeks of amenorrhoea and additional tests given by the MyCMV tool compared with the reference method.

研究组 & 干预措施
Patients
Pregnant women with prescription of a CMV serology including the search for CMV IgG and IgM antibodies, care at the Necker-Enfants Malades, Paul Brousse hospitals, or the CHU Limoges, with positive CMV IgM antibodies or in the grey zone of the technique and for whom the date of start of pregnancy is known.
干预措施: Reinterpretation of CMV serology results using the MyCMV tool on the basis of the serology results performed (Other)
结局指标
主要结局
Evaluation of the detection rate of primary CMV infection in the first trimester of pregnancy using the MyCMV tool
时间窗: Time 0
Detection of primary CMV infection in the first trimester of pregnancy by the MyCMV tool or by the reference method. In the context of this study, the reference method is the interpretation of the results by the expert investigator of the center, without using the MyCMV tool.
次要结局
- Dating in weeks of amenorrhea of the date of primary infection by the MyCMV tool and by the reference method(Time 0)
- Recommendations for the conduct to be adopted for carrying out additional analysis by the MyCMV tool(Time 0)
