RESUMO
OBJECTIVE: To assess risk factors, geographic distribution, length of stay, and total charges per case of symptomatic congenital cytomegalovirus infection (cCMV). STUDY DESIGN: We performed retrospective analyses of serial cross-sectional data using the Kids' Inpatient Database, a nationally representative sample of US pediatric hospital discharges, from 2000, 2003, 2006, 2009, and 2012. Symptomatic cCMV was identified via use of the International Classification of Diseases, Ninth Revision, Clinical Modification code 771.1 among records with in-hospital birth that were accompanied by 1 or more characteristic symptoms. Demographic characteristics were compared with multivariable logistic regression. Temporal trend was assessed using linear regression. Charges were adjusted for inflation to 2012 US dollars. RESULTS: We identified 1349 cases of symptomatic cCMV (SE 56). Symptomatic cCMV was associated with non-Hispanic black race (OR 1.70; 95% CI 1.37-2.10), government-sponsored insurance (OR 1.95; 95% CI 1.34-2.83), and birth in the American South and West (OR 1.68, 95% CI 1.35-2.09 and OR 1.61, 95% CI 1.23-2.09, respectively). In-hospital mortality and preterm birth rate ranged from 3.2%-6.8% and 50.4%-59.2%, respectively, without temporal changes. The geometric mean of total charges per case doubled from $45 771 (SE $8509) in 2000 to $89 846 (SE $10 358) in 2006 (P = .002) but did not change from 2006 to 2012. Length of stay in days was 15 (IQR 8-22) in 2000, 27 (IQR, 9-51) in 2009, and 18 (IQR, 8-47) in 2012. CONCLUSIONS: Symptomatic cCMV was associated with non-Hispanic black race, low socioeconomic status, and birth in the American South and West and resulted in substantial healthcare burden.

BACKGROUND: CMV is the most common cause of congenital infection in the whole world (0.2 to 2.2 %). That infection may be symptomatic or asymptomatic at birth and, although asymptomatic cases at birth are more common, some children may develop late sequelae, and require medical intervention. This study aimed to determine the prevalence of CMV congenital infections in children who were born in a public hospital in Ilhéus, Brazil, and to evaluate the clinical progression in infected newborns. METHODS: CMV congenital infection was determined by detecting viral DNA through nested PCR. RESULTS: The viral DNA was detected in 25 newborns, showing a prevalence of 1.19 % (25/2100) of CMV congenital infection. In regards to the risk factors from mothers, only the variables: age of mothers (p = 0.003), number of children (p = 0.011), and use of medications (p < 0.001) were associated with the congenital infection. Approximately 12 % of children presented symptoms. One death and two auditory alterations were detected during the monitored period. Only 50 % of children diagnosed attended their medical follow. CONCLUSIONS: The prevalence found confirms the findings from other studies which involved other poor populations. Two children presented impaired hearing during the monitored period; that was one of the main sequelae from the infection. It is noteworthy that there was low adherence to medical follow-up which may underestimate data on complications of the infection CMV. Late symptoms can be mistaken for other diseases or even go unnoticed.
