Sumario:BACKGROUND: Our objective was to evaluate the prevalence and different diagnostic methods of breastmilk (BM)‐acquired cytomegalovirus (CMV) infection in a pathologically jaundiced cohort. METHODS: A total of 400 infants confirmed with pathological jaundice at The People's Hospital of Qingyang City were screened for BM‐acquired CMV infection between February 2018 and February 2019. A total of 300 infants were finally enrolled in our study. CMV infection was confirmed by detecting both CMV‐DNA in various samples using FQ‐PCR and CMV‐IgM with chemiluminescence. Clinical and other laboratory data were collected from these infants during their hospitalization or regular visits. RESULTS: Ninety‐eight (32.67%) subjects were confirmed to be BM CMV‐DNA–positive, and 18 (18.37%) were diagnosed with a BM‐acquired CMV infection. All 18 (100%) infants with a BM‐acquired CMV infection were CMV‐DNA–positive in urine, while 5 (27.78%) cases and 11 (61.11%) cases were confirmed in plasma and peripheral blood mononuclear cells (PBMCs), respectively. Only 6 (33.33%) infants were CMV‐IgM–positive. Birthweight, direct bilirubin, aspartate aminotransferase, and the viral load in BM of the BM‐acquired CMV group were higher than those in the non‐infected group (P < .05). Low birthweight and viral load in BM were risk factors for BM‐acquired CMV infection. Detecting CMV‐DNA in urine samples exhibited better performance than the other methods for screening BM‐acquired CMV infections. CONCLUSIONS: Our study found a high prevalence of BM‐acquired CMV infection in jaundiced infants, and detecting CMV‐DNA in a urine sample was the most sensitive method for disease screening.
