Cranial Ultrasound (cUS) Comparisons in Asymptomatic and Symptomatic Infants Identified in a Univers
Background: With implementation of universal cCMV screening planned for 2023 in Minnesota (MN), it is imperative to define the optimal diagnostic approach for disease classification of identified cases. Cranial ultrasound (cUS) is typically recommended for evaluation of cCMV symptomatology. Method: Newborns were screened for cCMV at six MN nurseries by PCR of dried blood spots (DBS) and saliva. Screen-positive infants had confirmatory urine PCR by day of life 21 and a diagnostic evaluation. Results: Of 19,917 screened newborns, 76 had confirmed cCMV. 60 were asymptomatic (2 with delayed SNHL), 3 were asymptomatic with isolated SNHL at birth, 8 had mild symptoms, and 5 moderate-to-severe symptomatic disease (2 with SNHL at birth and 2 with delayed SNHL). Cranial US exams were available for 68 infants. In infants with any clinical cCMV manifestation, 12 of 17 had at least one abnormal cUS finding, versus 6 of 51 asymptomatic infants (p<0.0001, Fischer’s exact). Four infants with cUS abnormalities defined cases as symptomatic cCMV (DOI: 10.1016/S1473-3099(17)30143-3). Conclusion: The spectrum of cUS findings that define cCMV as “symptomatic” requires clarification. Nonspecific abnormalities are common, even in asymptomatic babies.
- Determine clinical manifestations of cCMV in infants identified in the context of a universal screening study.
- Characterize cranial US findings observed during diagnostic evaluation of confirmed cCMV cases.
- Examine relationship between viral load in saliva samples with clinical findings.
