Overview
This is an observational, prospective/retrospective multicentre, cohort study of children diagnosed with cCMV. This study will contribute to a wider study also recruiting participants in Europe and other countries worldwide. No investigations or treatment will be carried out that are not part of routine clinical practice. Infants with cCMV are routinely followed up from an infectious diseases, audiology, ophthalmology and neurodevelopmental perspective until approximately 6 years of age, or longer if there are ongoing issues. Some children will be retrospectively diagnosed with cCMV in later childhood. Recruitment can be from any centre that manages these patients and has agreed to participate in the study.
Detailed description
Cytomegalovirus (CMV) is the most frequent cause of congenital infection worldwide, occurring in 0.2-2% of live births. It is also the most frequent cause of non-genetic hearing loss, and an important cause of neurodevelopmental delay. Clinical diagnosis of maternal infection during pregnancy is unreliable in most patients and laboratory diagnosis can be challenging, especially in non-primary infections. Screening of congenital CMV infection (cCMV) in newborns is not recommended in most countries and only targeted screening is performed in some cases (children who fail hearing screening or with abnormalities compatible with cCMV in physical exams).
The main focus of the study is to identify patient and treatment characteristics that are associated with outcome. This will allow improved patient care in the future.
Primary outcome measures
- Measuring cases of cCMV in the UK [Time frame: 15 years]
- Clinical characteristics [Time frame: 15 years]
- To evaluate risk factors in children with cCMV for long term sequelae [Time frame: 15 years]
- Adverse events [Time frame: 15 years]
- To evaluate the prognostic value of microbiological variables [Time frame: 15 years]
- To evaluate the prognostic value of image findings [Time frame: 15 years]
- To evaluate associated outcomes with different treatment strategies [Time frame: 15 years]
Eligibility criteria
Inclusion Criteria: Patients of either sex that have been diagnosed with cCMV infection:
- Through confirmed detection of CMV in urine or saliva, by CMV-DNA PCR (or viral culture / Shell-vial) and/or CMV detection in blood or CSF by PCR within the first 21 days of life.
- Children with cCMV retrospectively diagnosis by positive CMV-DNA PCR in dried blood spots (DBS), collected within 21 days of life.
- Diagnosed by positive CMV-DNA PCR in dried umbilical cord blood or donated/stored umbilical cord blood sample
- Children whose parents give their informed consent to participate in the study
- Age less than 11 years old
