Cytomegalovirus-associated neonatal hepatitis

Area of Science:

• Neonatology
• Pediatric Hepatology
• Infectious Diseases

Background:

• Neonatal hepatitis (NH) is a significant cause of liver disease in newborns.
• Cytomegalovirus (CMV) is a common congenital infection that can cause neonatal hepatitis.

Purpose of the Study:

• To evaluate the long-term outcomes of infants diagnosed with CMV-associated neonatal hepatitis.
• To identify clinical and pathological factors associated with unfavorable outcomes in these patients.

Main Methods:

• A longitudinal follow-up study of 55 infants with CMV-associated NH.
• Data collection included clinical presentation, laboratory values, liver pathology, and developmental assessments up to 90 months.
• Statistical analysis to correlate clinical parameters with patient outcomes.

Main Results:

• Six patients (10.9%) died due to fulminant or chronic liver disease.
• Among 49 survivors, 20.4% experienced long-term impacts, including developmental/growth retardation and hearing impairment.
• Unfavorable outcomes were linked to persistent clay-colored stools, splenomegaly, ascites, anemia, high bilirubin, low albumin, giant cell transformation, and cirrhosis.
• CMV seropositivity did not significantly correlate with outcomes.

Conclusions:

• CMV-associated neonatal hepatitis carries a substantial risk of mortality and long-term sequelae in survivors.
• Specific clinical and pathological findings are critical indicators of prognosis, independent of CMV infection status.
• Early identification of these risk factors is crucial for managing infants with CMV-associated NH.
