Fighting Back the 'Silent' Global Burden of Congenital Cytomegalovirus Infection and Hearing Loss Related to Cytomegalovirus
Introduction: Congenital infection with the human cytomegalovirus (CMV) is the leading cause of congenital infections worldwide. In developed countries it is the most common non-genetic cause of a sensorineural hearing loss and an important cause of microcephaly, neurodevelopmental delay, seizure disorders, and cerebral palsy, with profound with impact on cognitive and social development of the affected children and their families (Manicklal et al. 2013).
Only 10% of congenital CMV infections lead to symptoms after birth; however, 50% of congenital CMV-related hearing loss emerges later in life. Prevalence numbers of congenital CMV infections given for middle Europe are up to 0.7% per 1,000 newborns, and for developing countries up to 1-5% (Manicklal et al. 2013).
Newborn screening programs for congenital CMV infections are under discussion. Antiviral therapy of symptomatic children has been shown to effectively reduce the risk of long-term impairments. Because an effective pre-conceptual vaccine against CMV could potentially prevent congenital CMV infection, a couple of active and passive immunization strategies are under clinical trials.
Method: In an international project* in Germany and Qatar, 12,000 neonates undergo a CMV screening by real-time PCR-based testing of liquid-saliva specimens. If a congenital CMV infection is confirmed, babies are enrolled in a 6-year follow-up program.
Results: By the end of April, 2016, cytomegalovirus-screenings of about 1200 German neonates and 270 Qatari neonates indicated congenital CMV infections in 3 German and 2 Qatari babies, who were enrolled in treatment and follow-up programs.
Conclusion: The high prevalence of congenital CMV infections and their lifelong sequelae call for action, with respect to the implementation of universal neonatal CMV screening, follow-up, prevention, and intervention programs that seem to be feasible and effective.

Norbert Teig (Author,Co-Author), University of Bochum, norbert.teig@rub.de;
Dr. Norbert Teig chairs the Dept. of Neonatology of the Ruhr-University Bochum. He has been involved in many clinical studies in neonatology since years (Simbruner et al. and neo.nEURO.network. Pediatrics 2010;126:e771-8; ETTNO Investigators. Neonatology 2012;101:301-305; Göpel et al. and German Neonatal Network. Lancet 2011;378:1627-34) and is member of the German Neonatal Network (GNN) which organizes a large prospective multicenter descritpive study, encompassing about 40 neonatal intensive care units and about 35% of all very preterm newborns in Germany. Important parts of these studies deal with getting informed consent of parents of newborns, performing oral swabs (for genetic studies in this case) and organizing the transfer of these specimens and data on a large scale basis (Spiegler et al. 2012; Härtel C et al. and German Neonatal Network [GNN](www.vlbwi.de). PLOS one 2012; Härtel et al. and German Neonatal Network. Crit Care Med 2011). He performs similar tasks in the study on congenital CMV infection described here.
