About this study

Official title: Incidence, Outcome and Prevention of Congenital Human Cytomegalovirus (HCMV) Infection in HCMV-seropositive Pregnant Women

Human cytomegalovirus (HCMV) is the leading infectious agent causing congenital disabilities such as mental retardation, psychomotor delay, hearing loss, speech and language disabilities, behavioural disorders and visual impairment. About 0.6% newborns are HCMV-congenitally infected and, among these, about 20% are symptomatic at birth or will develop long-term sequelae. The public health impact of congenital HCMV is substantial although greatly unrecognized. In Italy, estimated direct costs per affected child exceed €100.000 for a total of €60-70M. HCMV is also a significant cause of infection/disease in the immunocompromised host.

Epidemiological studies and population-based models have preliminarily documented that most of the burden associated to congenital HCMV would be due to non-primary maternal infection. Presently, reinfections are believed to be responsible for the great majority of infected fetuses born to immune mothers.

This study addresses incidence, outcome and prevention of congenital HCMV infection in seropositive pregnant women.The study includes 2 parts: part 1 in which the incidence and outcome of congenital HCMV is investigated in a large population of HCMV seropositive pregnant women and HCMV shedding and immune response is closely monitored in a subset of participants (nested study); part 2 in which the efficacy of an hygiene intervention is assessed.

Read the detailed description

Part 1. Epidemiologic study. To investigate incidence and outcome of congenital infection in immune mothers, clinical records of pregnant women are reviewed for HCMV serostatus at ≤ 13 weeks' gestation. Women with HCMV serology compatible with a remote infection are asked to participate in the study. Consenting women are given a pre-stamped, pre-addressed envelope containing a swab to collect newborn's saliva. Envelopes are sent by courier to a centralized diagnostic facility for HCMV testing.

Women can also be enrolled at delivery, provided that the woman has records of presence of virus-specific IgG and absence of IgM early during gestation(or in a previous pregnancy) or, in case of unknown serostatus, a sample of serum/plasma stored at ≤ 13 weeks' gestation is available for retrospective antibody testing (retrospective part of the epidemiology study).

Part 1. Nested study. A subset of IgG pos IgM neg women selected among those enrolled at ≤13 weeks' gestation in the epidemiology study are included in a nested study. These women are monitored at enrolment, 20, 30 weeks of gestation and at delivery by prospective determination of HCMV DNA excretion in different bodily fluids. In DNA-positive specimens selected HCMV genes will be sequenced.

Part 2. Prevention study. To assess the effectiveness of hygiene measures for prevention of congenital infection HCMV seropositive pregnant women are enrolled at ≤ 13 weeks' gestation. Part 2 starts when enrolment of Part 1 is completed. In practice, part 2 is a continuation of part 1 with the only addition of delivering hygiene information at enrolment.

Part 2 will not be performed in case congenital infection rate in Part 1 is <0.4% and clear maternal risk factor for intrauterine transmission cannot be identified at interim analysis (i.e. after examination of 5000 newborns).

In case HCMV DNA is detected in newborn's saliva, a urine sample is obtained for confirmation of congenital infection. Infants with documented congenital infection are clinically assessed at the time of diagnosis (for Part 1 and 2) and at one year of age (Part 1 only).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part 1. Epidemiology study. Incidence and clinical outcome of congenital HCMV infection in pregnant women with preconception immunity.

    Number of infants with ascertained congenital infection.

    Measured: Within 21 days of life

  2. Part 2. Prevention study. Efficacy of hygiene counseling in reducing congenital HCMV infection in pregnant women with preconception immunity.

    Number of infants with ascertained congenital infection born to HCMV seropositive women informed about hygiene measures compared to the number of newborns with congenital infection diagnosed in Part 1.

    Measured: Within 21 days of life

    Age in mothers of newborns with or w/o congenital HCMV infection

    Measured: Delivery

  7. Risk factors for congenital HCMV infection in pregnant women with preconception immunity. Country of origin

    Country of origin of mothers of newborns with or w/o congenital HCMV infection

  9. Risk factors for congenital HCMV infection in pregnant women with preconception immunity. Contact with young children

    Contact with children <36 months in mothers of newborns with or w/o congenital HCMV infection

    Measured: Delivery

  10. Risk factors for congenital HCMV infection in pregnant women with preconception immunity. Twin pregnancy

    Twin vs singleton pregnancy in mothers of newborns with or w/o congenital HCMV infection

    Measured: Delivery
